At this time, the first calendering roller 301 is raised and the fourth calendering roller 304 is lowered. The controller controls the horizontal hydraulic cylinder 342 to drive the composite film horizontal roller 344 away from the calendering machine 30. The machine is used for production operation, and the finished PVC composite film sheet is obtained.

f. When the first composite film is exhausted, the induction component A of the upper module 326 feeds back to the control machine, and the control machine controls the connecting rod driving device B of the lower module 327 to start to make the composite film clamping device C of the lower module 327 turn to the connecting component. D. After being in place, the controller controls the composite film clamping device C to open so that the second composite film is connected to the first composite film to complete the connection of the two composite films, and the controller controls the composite film clamping device C to reset.

g. While the composite film continuation device 32 is working, the controller controls the calender to control the first calender roll 301 to be away from the second calender roll 302 by about 1-2 mm, and the fourth calender roll 304 to be far away from the third calender roll 303 for about 1-2 mm mm, to avoid the thickness of the composite film becoming larger after bonding, which would cause the transverse force between the calendering rollers to rapidly increase and cause the calendering roller to be damaged. Under the guidance of the composite film horizontal roll 344 and the third calender roll 303, the calender 30 is pulled out after the PVC bottom plate is simply attached, and then the controller controls the two composite film horizontal rolls 344 away from the third calender roll 303, and the controller controls the calender to control The first calendering roll 301 and the fourth calendering roll 304 return to continue the production of the PVC composite film sheet.

h. Paste double-sided adhesive or heat-sealing adhesive film on the lower surface of the new first composite film as shown in Figure 12 (choose cold-sealing adhesive method or heat-sealing adhesive method according to the properties of different composite films).

i. Two workers open the upper module 326 and clamp the new first composite membrane to the composite membrane clamping device C of the upper module 326 .
