Specifically, when working, the wire loading disc 113 can rotate synchronously with the wire loading shaft 112 .

The wire feeding assembly 120 is mounted on the frame. The wire feeding assembly 120 includes a wire feeding driving member 121 , a driving wheel 122 and a driven wheel 123 . The driving wheel 122 has a guiding surface 1221 , and the driven wheel 123 has a mating surface 1231 , and the guiding surface 1221 is opposite to the mating surface 1231 to form a wire feeding channel 124 aligned with the wire loading shaft 112 . The wire-feeding driving member 121 is in drive connection with the driving wheel 122 and the driven wheel 123 respectively.

The driving wheel 122 is opposite to the driven wheel 123 , and a wire feeding channel 124 is formed between the guiding surface 1221 and the mating surface 1231 . The wire feeding driving member 121 drives the driving wheel 122 and the driven wheel 123 to rotate, and the wire 200 located in the wire feeding channel 124 can slide in the wire feeding channel 124 driven by the driving wheel 122 and the driven wheel 123 to realize wire feeding.

Specifically, when feeding the wire, the wire 200 installed on the wire loading shaft 112 is pulled, so that the wire 200 passes through the wire feeding channel 124, and then the driving wheel 122 and the driven wheel 123 rotate, which can drive the wire 200 to move along the back direction. The direction of the wire loading assembly 110 slides.

In this embodiment, the wire feeding assembly 120 further includes a pulley 125 , a first endless belt 126 , a second endless belt 127 , a first rotating shaft 128 and a second rotating shaft 129 . The first rotating shaft 128 and the second rotating shaft 129 are rotatably installed on the machine frame. The first rotating shaft 128 and the second rotating shaft 129 are arranged in parallel and spaced apart, and extend along the length direction perpendicular to the wire feeding channel. The belt pulley 125 is in transmission connection with the wire feeding driving member 121 , the first endless belt 126 is sleeved on the belt pulley 125 and the first rotating shaft 128 , and the second endless belt 127 is sleeved on the belt pulley 125 and the second rotating shaft 129 . The driving wheel 122 is sleeved on and fixed on the first rotating shaft 128 , and the driven wheel 123 is sleeved on and fixed on the second rotating shaft 129 .

The wire feeding driving member 121 is a driving motor, and the pulley 125 is sheathed and fixed on the rotating shaft of the driving motor. The side surface of the pulley 125 is provided with a plurality of annular grooves, and the plurality of annular grooves are arranged at intervals along the extending direction of the rotating shaft of the driving motor. The first rotating shaft 128 and the second rotating shaft 129 are arranged parallel to and spaced apart from the wire loading shaft 112 . The length direction of the wire feeding channel 124 is perpendicular to the extension direction of the wire loading shaft 112 .

One end of the first endless belt 126 is sleeved on an annular groove of the pulley 125 , and the other end is sleeved on the first rotating shaft 128 . One end of the second endless belt 127 is sleeved on another annular groove of the pulley 125 , and the other end is sleeved on the second rotating shaft 129 . Therefore, the rotating shaft of the driving motor can drive the first rotating shaft 128 and the second rotating shaft 129 to rotate through the first endless belt 126 and the second endless belt 127, and then drive the driving wheel 122 and the driven wheel 123 to rotate to realize wire feeding.

By setting the pulley 125, the first endless belt 126, the second endless belt 127, the first rotating shaft 128 and the second rotating shaft 129, the whole transmission process runs smoothly and has low vibration, thereby facilitating the stable rotation of the driving wheel 122 and the driven wheel 123 .

Moreover, by arranging the pulley 125, the first endless belt 126, the second endless belt 127, the first rotating shaft 128 and the second rotating shaft 129, it is also possible to achieve multiple rotating shafts under the setting of a single wire feeding drive member 121. transmission, so that the arrangement of components can be effectively reduced, so that the wire feeding device 100 has a compact structure.

Specifically, during installation, the wire feeding channel 124 has a feeding side and a feeding side, and the wire feeding assembly 120 is located at the feeding side of the wire feeding channel 124 . In the electric explosion device, the electric explosion housing is arranged on the side of the wire feeding assembly 120 away from the wire guide assembly 130 , and the electric explosion chamber communicates with the wire feeding channel 124 . That is, the electric explosion shell is located at the discharge side of the wire feeding channel 124 , and the electric explosion chamber communicates with the wire feeding channel 124 at the discharge side. Therefore, the metal wire 200 can enter into the electric explosion chamber under the transmission action of the driving wheel 122 and the driven wheel 123 to perform the electric explosion operation.

Further, in this embodiment, the wire feeding device 100 further includes a casing 140 disposed on the frame. The casing 140 is a hollow structure. The wire feeding assembly 120 is accommodated in the casing 140, and the side wall of the casing 140 is provided with a wire inlet hole 141 and a wire outlet hole 142, the wire inlet hole 141 and the wire outlet hole 142 are respectively located at two ends of the wire feeding channel 124, and respectively It communicates with the wire feeding channel 124.

During specific arrangement, the wire feeding driving member 121 , the driving wheel 122 , the driven wheel 123 , the pulley 125 , the first endless belt 126 , and the second endless belt 127 are all accommodated in the casing 140 . The first rotating shaft 128 and the second rotating shaft 129 pass through the casing 140 .

By providing the housing 140 , the wire feeding assembly 120 is accommodated in the housing 140 , which can prevent the external environment from affecting the operation of the wire feeding assembly 120 , so that the wire feeding assembly 120 can work stably.

In this embodiment, the wire inlet hole 141 and the wire outlet hole 142 are both arranged on the side wall of the housing 140, the wire inlet hole 141 is located at the feed side of the wire feeding channel 124, and the wire outlet hole 142 is located at the outlet of the wire feeding channel 124. On the material side, the wire inlet hole 141 and the wire outlet hole 142 are aligned with the wire feeding channel 124, and both the wire inlet hole 141 and the wire outlet hole 142 extend along the length direction of the wire feeding channel. The thread outlet hole 142 communicates with the electric explosion chamber.

Specifically, the diameters of the wire inlet hole 141 and the wire outlet hole 142 are slightly larger than the diameter of the metal wire 200 . Therefore, during the transmission process of the wire 200 , the inner walls of the wire inlet hole 141 and the wire outlet hole 142 also have guiding and limiting functions for the wire 200 . On the one hand, during the transmission process, the inner walls of the wire inlet hole 141 and the wire outlet hole 142 can limit the metal wire 200 from the two ends of the metal wire 200 being conveyed, which can prevent the metal wire 200 from shaking, and then make the metal wire 200 The wire 200 can precisely pass through the wire feeding channel 124 to realize wire feeding.

On the other hand, during the transmission process of the metal wire 200, when the metal wire 200 is greatly deformed and becomes warped, the inner walls of the wire inlet hole 141 and the wire outlet hole 142 are squeezed against the warped part of the metal wire 200, To prevent the metal wire 200 from being deformed too much, so that the metal wire 200 can always maintain a relatively straight state, so that the metal wire 200 can be aligned with the electrodes in the electric explosion chamber to realize the electric explosion.

Therefore, by setting the casing 140, not only the transmission process of the metal wire 200 is stabilized, but also the metal wire 200 can be kept relatively straight during the transmission process, thereby having a better electric explosion effect.

Specifically, the casing 140 can be made of metal, plastic or other materials.

In this embodiment, the wire feeding device 100 further includes a brake (not shown) installed on the frame. The brake is used to clamp or loosen the driving wheel 122 and the driven wheel 123 .

Specifically, the brake is accommodated and fixed in the casing 140 . When the electric explosion equipment breaks down and needs to stop working in time, the brake clamps the driving wheel 122 and the driven wheel 123 to stop the wire feeding. Therefore, by setting the brake, it is possible to prevent the driving wheel 122 and the driven wheel 123 from continuing to rotate in the presence of inertia, causing the wire 200 entering the electric explosion chamber to be too long and causing the next electric explosion to fail.

Specifically, the brake can be a clamping member that clamps the driving wheel 122 and the driven wheel 123, for example, a hoop that has the same size as the driving wheel 122 and the driven wheel 123, or it can be two clamps that clamp the driving wheel 122 and the driven wheel 123. a clamp etc. The brake also includes a brake driver, which is connected to the hoop, the clamp block, etc., and is used to drive the hoop to hold the driving wheel 122 and the driven wheel 123 tightly, or drive the clamp block to clamp the driving wheel 122 and the driven wheel 123 .

The wire guide assembly 130 is mounted on the frame. The wire guide assembly 130 is located between the wire loading assembly 110 and the wire feeding assembly 120 . The guide wire assembly 130 includes a guide wire driver 131 , a guide wire tube 132 and a clamping member (not shown). The wire guide tube 132 extends along the length of the wire feeding channel 124 and is aligned with the wire loading shaft 112 and the wire feeding channel 124 . The guide wire driving member 131 is in transmission connection with the clamping member, and the clamping member is located at the end of the guide wire tube 132 away from the wire loading assembly 110 . The clamping part is used to clamp the metal wire 200 , and the guide wire driving part 131 is used to drive the clamping part to slide along the length direction of the wire feeding channel 124 .

The wire guide assembly 130 is used to straighten the wire 200 . Because the metal wire 200 is wound on the wire loading shaft 112 when the wire is loaded, therefore, during the wire feeding process, the bent and lifted metal wire 200 will cause the metal wire 200 to be possibly separated from the wire when passing through the wire inlet hole 141. Friction is generated between the inner walls of the wire 200 . Moreover, the warped metal wire 200 may be resisted outside the casing 140 and cannot pass through the wire inlet hole 141 smoothly.

In this embodiment, by setting the guide wire assembly 130 between the wire loading assembly 110 and the wire feeding assembly 120, the metal wire 200 can be straightened before passing through the wire inlet hole 141 and the wire outlet hole 142, so that the metal The wire 200 can be transported stably and smoothly, thus having better reliability.

When the wire guide assembly 130 is working, the wire guide tube 132 extends along the length direction of the wire feeding channel 124 and is aligned with the wire feeding hole 141 and the wire feeding channel 124 . The bent wire 200 is conveyed within the wire guide tube 132 . Although the driving wheel 122 and the driven wheel 123 rotate, the metal wire 200 can also be driven to pass through the wire guide tube 132 . However, the metal wire 200 is driven by friction between the driving wheel 122 and the driven wheel 123 . If when the wire 200 is relatively curved, the friction force is smaller than the resisting force of the wire guide tube 132 on the warped part of the wire 200 , the friction force between the driving wheel 122 and the driven wheel 123 will not be able to pull the wire 200 forward. Therefore, when the driving wheel 122 and the driven wheel 123 rotate to drive the wire 200 to run, the wire 200 needs to be straightened in advance.

And by setting the clamping part, the clamping part can clamp the wire 200 and pull the wire 200 to slide along the axial direction of the wire guide tube 132 . The opening end face and edge of the opening of the wire guide tube 132 facing the wire loading assembly 110 has a pressing effect on the bent wire 200 , and then the wire 200 is forced to straighten through the clamping member sliding along the axial direction of the wire guide tube 132 .

Therefore, by setting the guide wire assembly 130 , the metal wire 200 entering the wire inlet hole 141 is relatively straight, so as to facilitate the transportation of the metal wire 200 and improve the stability and reliability of the transmission.

Specifically, the moving speed of the clamping part needs to be consistent with the speed at which the driving wheel 122 and the driven wheel 123 pull the wire 200, so that the running speed of the metal wire 200 in the clamping part is inconsistent with that of the driving wheel 122 and the driven wheel 123 can be avoided. Under the circumstances, the metal wire 200 is bent again.

In this embodiment, preferably there are two clamping parts, and the two clamping parts are respectively disposed on opposite sides of the wire guide tube 132 and located between the wire guide tube 132 and the housing 140 . Each clamp has a start position and an end position. The initial position is near the wire guide tube 132 . The end position is close to the housing 140 . When the clamping member pulls the wire 200 and moves toward the wire feeding assembly 120 to the housing 140 , the clamping member stops moving. At this time, the clamping part on the other side is in the starting position and is ready for use. When the clamping part on one side stops moving, the clamping part on the other side clamps the wire 200 and pulls the wire 200 to slide towards the wire feeding assembly 120 . And the clamping part positioned at one side of the guide wire tube 132 slides in the opposite direction and gets back to the starting position again to be on standby for the next operation.

By arranging at least two clamping parts, the wire guide assembly 130 can guide and straighten the metal wire 200 uninterruptedly, so that the wire feeding device 100 has better movement reliability.

It should be noted that when there are multiple clamping parts, the clamping parts can be distributed on both sides of the wire guide tube 132, and the number of clamping parts on both sides of the wire guide tube 132 can be equal or different.

In this embodiment, the wire guide assembly 130 further includes a guide wire sliding rail 134 extending along the length direction of the wire feeding channel 124 . The clamping part is disposed on the guide wire slide rail 134 , and the guide wire driving part 131 can drive the clamping part to slide along the extending direction of the guide wire slide rail 134 .

By setting the wire guide rail 134 , the clamping member can be prevented from swinging during the movement, so that the metal wire 200 can pass through the wire feeding channel 124 precisely, thus having better wire feeding stability.

In this embodiment, the wire guide assembly 130 further includes a clamping driver 135 and a clamping slide rail 136 . The clamping slide 136 extends in a direction perpendicular to the length of the guide wire slide 134 . The clamping slide rail 136 is disposed on the guide wire slide rail 134 and is in transmission connection with the guide wire driving member 131 . The clamping member includes a first clamping plate 1331 and a second clamping plate 1332 . The first clamping plate 1331 is fixed on the clamping slide rail 136 , and the second clamping plate 1332 is disposed on the clamping slide rail 136 and is in transmission connection with the clamping driving member 135 . The clamping driver 135 is used to drive the second clamping plate 1332 to slide along the clamping slide rail 136 to clamp or separate the second clamping plate 1332 from the first clamping plate 1331 .

Specifically, the first clamping plate 1331 and the clamping driving member 135 are both fixed on the clamping slide rail 136 through a fixing block, and the second clamping plate 1332 is arranged on the clamping slide rail 136 through a slider, and is in transmission connection with the clamping driving member 135 . The clamping driver 135 is used to drive the second clamping plate 1332 to slide along the clamping slide rail 136 to clamp or separate the second clamping plate 1332 from the first clamping plate 1331 .

The clamping driver 135 drives the second clamping plate 1332 to slide along the clamping slide rail 136, so that the second clamping plate 1332 can gradually approach the first clamping plate 1331, so that the wire 200 can be clamped between the first clamping plate 1331 and the second clamping plate 1332 between. Furthermore, the guide wire transmission part drives the clamping slide rail 136 to slide along the guide wire slide rail 134 , and can drive the metal wire 200 to slide along the length direction of the wire feeding channel 124 . When the clamping member moves to the housing 140 , the clamping driver 135 drives the second clamping plate 1332 to slide in a direction away from the first clamping plate 1331 , and the first clamping plate 1331 is separated from the second clamping plate 1332 . Furthermore, the guide wire driving part 131 drives the clamping part and the clamping slide rail 136 to slide in reverse, so that the clamping part returns to the initial position. When the clamping part returns to the initial position, the other clamping part on the side opposite to the clamping part clamps the wire 200 and moves towards the wire feeding assembly 120 .

Therefore, by setting the clamping driver 135 and the clamping slide rail 136, the clamping piece slides along the clamping slide rail 136 under the drive of the clamping driver 135, so that the movement of the clamping piece is stable, thereby increasing the size of the wire 200. The stability of the transmission prevents the metal wire 200 from shaking during the movement.

Moreover, the second clamping plate 1332 slides along the clamping slide rail 136, so that the clamping part can be clamped or released from the wire 200, so as to realize the function of the clamping part.

The way in which the second clamping plate 1332 slides along the clamping slide rail 136 makes the clamping or separating operation of the clamping parts simple and facilitates the improvement of work efficiency.

In this embodiment, the wire feeding device 100 further includes an adjustment member 150 . The adjusting member 150 is used for adjusting the distance between the first rotating shaft 128 and the second rotating shaft 129 .

Since the driving wheel 122 is sleeved and fixed on the first rotating shaft 128, and the driven wheel 123 is sleeved and fixed on the second rotating shaft 129, therefore, the distance between the first rotating shaft 128 and the second rotating shaft 129 changes, which will cause the driving The distance between the wheel 122 and the driven wheel 123 varies, thereby making the size of the wire feeding channel 124 adjustable. By adjusting the distance between the first rotating shaft 128 and the second rotating shaft 129, the size of the wire feeding channel 124 can be adjusted according to the diameter of the metal wire 200, so that when the metal wire 200 passes through the wire feeding channel 124, it can Driven by the driving wheel 122 and the driven wheel 123, it smoothly passes through the wire feeding channel 124 and enters into the electric explosion chamber.

Specifically, the adjusting member 150 may be a pin shaft, an adjusting bolt or other components. Specifically, in this embodiment, the adjusting member 150 is an adjusting bolt. The frame is provided with two first installation parts and two second installation parts. The two first installation parts are fixed on the frame and located at opposite ends of the first rotating shaft 128 . The first rotating shaft 128 is rotatably mounted on the two first mounting portions. The two second mounting portions are located at opposite ends of the second rotating shaft 129 and correspond to the positions of the two first mounting portions one by one. The second mounting portion is connected to the corresponding first mounting portion through an adjusting bolt, and the second rotating shaft 129 is rotatably mounted on the second mounting portion.

The adjusting bolts are in one-to-one correspondence with the positions of the first mounting portion or the second mounting portion.
