Alternatively, as shown in fig. 3, it may be a vertical four-roll calender, which has a structure that two feeding rolls 37, a mirror roll 38 and an embossing roll 34 are respectively disposed on the frame from bottom to top. In the three calender 30 structures, the embossing 341 having the same pattern as the surface pattern of the printing layer 12 is formed on the surface of the embossing roll 34, so that when the substrate 11, the printing layer 12 and the wear layer 13 are rolled together, a three-dimensional pattern corresponding to the pattern of the printing layer 12 is formed on the outer surface.
The registration system 40 comprises at least a first sensor 41, a second sensor 42 and a tension adjuster 43, wherein:
the first sensor 41 can be an electric eye or a video camera, and is disposed at the starting position of the conveying path of the printing layer 12, and the printing layer 12 is disposed corresponding to an outer side of the first sensor 41, and a plurality of positioning origins 121 are disposed at equal intervals according to a predetermined length distance, and 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 information of each positioning origin 121 of the printing layer 12 to the electronic control unit 50.
The second sensor 42 is used for sensing the angle and position of the embossing roller 34 during rotation, at least a starting origin 342 is disposed at a suitable position of the embossing roller 34, and the second sensor 42 is used to transmit information of each detection of the starting origin 342 to the electronic control unit 50.

The tension adjuster 43 is provided at an appropriate position outside of the transport start end of the printed layer 12, and adjusts the tension when the printed layer 12 is transported.
The electronic control unit 50 is electrically connected to the rolling device 20, the calender 30 and the registration system 40, 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, 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.
Meanwhile, when the electronic control unit 50 receives the signal of the initial origin 342 of the embossing roller 34, the operation module 51 is used to simulate the circumferential length of the embossing roller 34 and divide the embossing roller 34 into a plurality of equal parts, and the number of the equal parts is the same as the number of the simulated division of the printing unit 122, so as to compare the simulated data of the printing layer 12 with the simulated data of the embossing roller 34, and 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-resistant layer 13, and if 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, so as to adjust the error between the embossing 341 of the embossing roller 34 and the pattern of the printing layer 12. In principle, the larger the number of divisions of the printing unit 122 and the embossing roller 34, the finer the error determination value, and the more accurate the adjustment.
In addition, when adjusting the error between the emboss 341 of the embossing roller 34 and the pattern of the printed layer 12, besides the adjustment by the tension adjuster 43, the adjustment can also be performed by matching the rotation speed of the embossing roller 34 and increasing the fine adjustment, the fine adjustment of the embossing roller 34 is performed by matching a third or fourth sensor 44, 45 with the positioning detection roller 39 to determine in advance whether there is an error between the emboss 341 of the embossing roller 34 and the pattern of the printed layer 12, if so, the tension of the printed layer 12 is adjusted by the tension adjuster 43, and then the fine adjustment is performed by the rotation speed of the embossing roller 34. The arrangement of the third or fourth sensor 44, 45 and the positioning detection roller 39 varies from one calender 30 to another, wherein:

Or as shown in fig. 2, if the rolling device 20 has a pre-pasting roller 35 for pre-pasting the substrate 11, the printing layer 12 and the wear layer 13, a fourth sensor 45 may be disposed at a suitable position adjacent to the pre-pasting roller 35, after the printing layer 12 is pre-pasted with the substrate 11 and the wear layer 13, the fourth sensor 45 is used to transmit information of each positioning origin 121 of the printing layer 12 to the electronic control unit 50, and after the electronic control unit 50 receives the signal of the positioning origin 121 transmitted by the fourth sensor 45, the actual stroke of the printing layer 12 transmitted from the first sensor 41 to the second sensor 42 is compared with whether the actual stroke is the same as the simulated transmission stroke by the computing module 51, so as to be used as a basis for determining in advance whether the pattern of the printing layer 12 is accurately aligned with the emboss 341 of the embossing roller 34. If the compared data shows that the conveying speed of the printing layer 12 is too fast or slow, the tension of the printing layer 12 can be adjusted by the tension adjuster 43, and the error between the emboss 341 of the embossing roller 34 and the pattern of the printing layer 12 can be adjusted by adjusting the rotation speed of the embossing roller 34.
Therefore, the operation module 51 is used for receiving the numerical values of the first and second sensors 41 and 42 as the basis for the simulation division of the printing unit 122 and the embossing roller, comparing the simulation-divided numerical values through simulation conveying to accurately judge the error between the embossing 341 of the embossing roller 34 and the pattern of the printing layer 12, and adjusting the error through the tension adjuster 43 and the embossing roller 34, so that the components of the sensing and positioning equipment can be reduced, the roll-formed three-dimensional pattern can be accurately positioned, the cost is reduced, and the production quality and efficiency are improved.
