The adjusting unit 60 is disposed at an outer side or a lower position corresponding to the movable end 37, and one end of the adjusting unit is linked with the movable end 37 for driving the movable end 37 to perform a fine adjustment displacement of the position. The structure at least comprises a power source 61 and an expansion link 62 arranged at one end of the power source 61, the expansion link 62 can be driven by the power source 61 to apply a displacement power to the movable end 37, and the power source 61 can be controlled manually or electrically. The detailed implementation structure is described later:

first, as shown in fig. 1 and 2, when the adjusting unit 60 is disposed below the movable end 37 of the embossing roll 34, two power sources 61 may be provided, and the telescopic rod 62 at one end of each power source 61 is inserted into the frame 31 and then interlocked with the straddle 38.

If the power sources 61 of this embodiment are manually controlled, each power source 61 is internally provided with a gear box of a gear transmission mechanism, and an external side of one power source 61 is provided with a linking handle 64, and an external side of the opposite end is in transmission connection with another power source 61' by using a linking rod 63, and the linking rod 63 is provided with a clutch element 65, so that two ends of the linking rod 63 can be connected or disconnected for use. When the clutch element 65 is connected, the two power sources 61, 61' can be driven to rotate simultaneously by the rotation of the linking handle 64, so as to drive the movable end 37 to move up and down horizontally; when the clutch element 65 is disengaged, the rotation of the linking handle 64 can only drive a power source 61 to operate alone, so as to drive the movable end 37 to perform the ascending and descending adjustment with an inclined angle on one side.

As shown in fig. 4, if the adjusting unit 60 is electrically controlled, each of the power sources 61 can be a servo motor and is electrically connected to a controller 66, and the controller 66 can control the operation of the power source 61 through an electronic signal to drive the movable end 37 to move.

Furthermore, as shown in fig. 3 and 5, when the adjusting unit 60 is disposed outside the movable end 37 of the pressing roller 35, a single power source 61 can be disposed, the telescopic rod 62 at one end of the power source 61 is connected to the outside of the independent frame plate 71, and when the power source 61 drives the telescopic rod 62 to operate, the movable end 37 can move and adjust along the slide rail 311.

the first sensor 41 can be an electric eye or a camera, and is disposed at the starting position of the transportation path of the printing layer 12, and as shown in fig. 7, the printing layer 12 is disposed at a plurality of positioning origins 121 at equal intervals according to a predetermined length distance corresponding to the outer side of the first sensor 41, the length between each positioning origin 121 and the other adjacent positioning origins 121' is based on the circumferential length of the embossing roller 34, so as to form a printing unit 122, and in practical applications, the circumferential length of the embossing roller 34 is preferably slightly greater than the length of the printing unit 122. The first sensor 41 is used to transmit the information of each positioning origin 121 of the printing layer 12 to the electronic control unit 50.

The second sensor 42 is used to sense the angle and position of the embossing roller 34 during rotation, and at least one starting point 342 is disposed at a suitable position of the embossing roller 34, and the second sensor 42 is used to transmit the information of each detection of the starting point 342 to the electronic control unit 50.

The initial origin 342 can be disposed at a suitable position on an outer side of the embossing roll 34, the initial origin 342 can be a signal receiving element, the second sensor 42 can emit a light signal, and when the embossing roll 34 rotates, the light signal emitted by the second sensor 42 contacts the initial origin 342 to transmit a sensed signal to the electronic control unit 50.

The tension adjuster 43 is provided at an appropriate position outside the transport start end of the printed layer 12, and adjusts the tension when the printed layer 12 is transported.

The third sensor 44 can be disposed outside the embossing roller 34 and the pressing roller 35 for roll-forming the printing layer 12, or on the conveying path of the finished product after roll-forming, for sensing whether the positioning origin 121 on both sides of the printing layer 12 is on a horizontal straight line or generates an angular deviation, and transmitting a signal to the electronic control unit 50.

The electronic control unit 50 is electrically connected to the rolling device 20, the calender 30, the registration system 40 and the adjustment unit 60, and has a computing module 51, when receiving the sensing signal of each positioning origin 121 of the printing layer 12, the computing module 51 performs a number of average divisions on each printing unit 122 as shown in fig. 8, and constructs a simulation state of continuous transportation according to the stroke distance and the transportation speed of the printing layer 12 from the transportation origin to the embossing roller 34.

As shown in fig. 9A and 9B, when the electronic control unit 50 receives the signal of the initial origin 342 of the embossing roller 34, the computing module 51 is used to simulate the circumferential length of the embossing roller 34 to divide a plurality of the embossing roller 34 into a number equal to the number of the simulated divisions of the printing unit 122, and then the simulated data of the printing layer 12 is compared with the simulated data of the embossing roller 34 to determine whether the embossing 34 is exactly opposite to the pattern of the printing layer 12 when the embossing roller 34 rolls and molds the substrate 11, the printing layer 12 and the wear layer 13, and if the speed of the printing layer 12 is too fast or too slow, the tension of the printing layer 12 can be adjusted by the tension adjuster 43 to adjust the tension of the printing layer 12, so as to adjust the error between the 341 of the embossing roller 34 and the pattern of the printing layer 12. Secondly, if the electronic control unit 50 receives the signal that the printed layer 12 side generates deviation, the deviation value can be calculated by the deviation angle, and then the adjustment unit 60 is controlled to drive the movable end 37 to correct the deviation value, so that the pattern lines and the concave-convex embossing 341 are accurately opposite.
