Description

Pressing wheel

Technical Field

The invention relates to the field of packaging equipment, in particular to a pressing wheel applied to a carton sealing machine.

Background

The carton is a disposable box body used for packaging various goods, generally has a cubic structure, the front, back, left and right vertical surfaces of the carton are formed by complete paperboards, the upper and lower surfaces of the carton are sealed by two oppositely-opened swing wings, the aligned parts of the two swing wings form a linear seal of the whole carton, and the seal is generally adhered and sealed by wide adhesive tapes in a seam riding mode. A carton sealing machine is an apparatus that replaces manual closing of carton seals.

Chinese patent No. 93223625.1, "carton tape capper", discloses a carton capper that is currently most widely used in the market. As shown in fig. 1, the carton sealing machine is composed of a frame, a front pinch roller assembly 8, a rear pinch roller assembly 9, a connecting rod tension spring assembly 10, a tape cutting assembly 11, a tape adjusting assembly 12 and the like. When the front pinch roller assembly 8 is lifted, the adhesive tape on the front end face of the carton is sealed, and when the rear pinch roller assembly 9 is lowered, the adhesive tape on the tail end face of the carton is sealed. The connecting rod tension spring assembly 10 is connected with the front and rear pinch roller assemblies 9, synchronous lifting of the front and rear pinch roller assemblies 9 is achieved, and sealing of the adhesive tape on the plane of the carton is achieved when the bottom edges of the front and rear pinch rollers rise to equal-height positions. The adhesive tape cutting assembly 11 is a rotatable cutter, and when the current pinch roller assembly 8 recovers to a vertical state, the adhesive tape cutting assembly 11 rotates afterwards, and the blade falls to the adhesive tape and cuts off the adhesive tape by utilizing the self gravity (the torsional spring can also be arranged on the adhesive tape cutting assembly 11). The blade of the tape severing assembly 11 is very sharp and workers, both during operation of the carton sealing machine and while maintaining the carton sealing machine, must be very careful to avoid the blade or be vulnerable to injury.

Disclosure of Invention

The invention aims to solve the technical problems that the carton sealing machine in the prior art is required to be provided with a separate adhesive tape cutting assembly, the structure is increased, and the cutting edge of the adhesive tape cutting assembly is directly exposed outside, so that the carton sealing machine has potential safety hazards.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows: a pinch roller comprises a pinch roller body, a blade, a connecting rod, a rotating shaft, a pressing block, a return spring and an electromagnet;

the pinch roller body is cylindrical, a gap along the axial direction of the pinch roller body is arranged on the side surface of the pinch roller body, the blade is hidden in the gap and is connected with one end of a connecting rod, the connecting rod is arranged in an inner cavity of the pinch roller body through a rotating shaft, and the connecting rod can rotate around the rotating shaft;

the pressing block, the reset spring and the electromagnet are all arranged in an inner cavity of the pressing wheel body, part of the connecting rod is located between the pressing block and the electromagnet, the electrified electromagnet attracts the pressing block to be close to and stirs the connecting rod to rotate, and the stirred connecting rod drives the blade to rotate so that the cutting edge of the blade protrudes out of the side face of the pressing wheel body; the reset spring drives the pressing block and the connecting rod to reset under the condition that the electromagnet is powered off.

The pinch roller of the invention is used for replacing the pinch roller of the front pinch roller component of the carton sealing machine in the prior art. The conventional press roller is generally a cylindrical roller made of plastic and plays a role of flattening the adhesive tape. The press wheel of the invention is provided with a blade in the press wheel body, and the press wheel of the invention only has more thin gaps on the side surface from the appearance, and the gaps hardly affect the operation of the press wheel for flattening the adhesive tape. When the whole front pinch roller assembly finishes the work of flattening the adhesive tape, the electromagnet is electrified, and the blade hidden in the gap protrudes to rapidly cut off the adhesive tape; the electromagnet is then de-energized and the return spring causes the blade to retract back into the gap. Whole pinch roller has had the sticky tape of traditional cardboard box capper to cut off the function of subassembly concurrently.

Furthermore, the number of the gaps is multiple, a blade, a connecting rod and a rotating shaft are arranged in each gap, and all the gaps are uniformly arranged around the central axis of the pressing wheel body; when the electromagnet is electrified, all the blades synchronously protrude; the side surface of the whole pinch roller is only partially tightly attached to the adhesive tape, and the number of blades is increased, so that the adhesive tape can be accurately and rapidly cut off by packaging the electromagnets once and electrifying the electromagnets.

Further, the blade edge of the blade is serrated.

Has the advantages that: (1) the pressing wheel is internally provided with the blade, and the front pressing wheel assembly adopting the pressing wheel has the function of an adhesive tape cutting assembly of the traditional carton sealing machine, so that the structure of the carton sealing machine is simplified. (2) The blade of the pinch roller is exposed only in a very short time when the adhesive tape is cut off, and the rest of the blade is hidden in the pinch roller, so that the pinch roller has stronger safety. (3) The side surface of the pressing wheel is uniformly provided with a plurality of blades, so that the adhesive tape can be cut off quickly by one-time knife drawing. (4) The blade of the blade hidden in the pinch roller is serrated, so that the adhesive tape is easier to cut.
