[0020] like Figure 1The winding device for the PVC film calender shown includes: a controller 18, a frame 1, a first driving roller 11, a second driving roller 12, a PVC film roll 4, a gantry 10, a suspension rod 5, a floating plate 14 and a pressure roller 13. The first driving roller 11 and the second driving roller 12 are arranged in the frame 1 with a front-to-back lateral spacing. In this embodiment, the frame 1 is provided with a motor for driving the first driving roller 11 to rotate, and one end of the first driving roller 11 and the second driving roller 12 is provided with a synchronous wheel 17, and a synchronous belt 16 is provided between the two synchronous wheels 17 for synchronous rotation.

[0021] The PVC film reel 4 is disposed above the first driving roller 11 and the second driving roller 12 . The PVC film reel 4 is driven to rotate by the rotation of the first driving roller 11 and the second driving roller 12 , thereby winding the PVC film.

[0022] The gantry 10 is set on the frame 1 and is located above the first driving roller 11 and the second driving roller 12. The floating plate 14 is set in the gantry 10 in a liftable manner. In the present embodiment, a guide rod 7 is set on the top of the floating plate 14 and penetrates the gantry 10 upward. The guide rod 7 is used to guide the floating plate 14 to be lifted and lowered.

[0023] A mounting plate 9 is provided on the top of the guide rod 7, and a lifting drive device 8 connected to the gantry 10 is provided on the mounting plate 9 to realize the lifting and lowering drive of the mounting plate 9, and to drive the lifting and lowering of the floating plate 14 through the guide rod 7. In this embodiment, the lifting drive device 8 adopts an oil cylinder or an electric telescopic rod, and the controller 18 is connected to the lifting drive device 8 to perform lifting control. The controller 18 can adopt a PLC controller, which is easy to operate.

[0024] The suspension rod 5 is vertically arranged on both sides of the floating plate 14 so as to be longitudinally movable, and the bottom end of the suspension rod 5 extends downward to the outside of the corresponding end of the PVC film roll 4, and the pressure roller 13 is arranged at the bottom end of the suspension rod 5 and extends longitudinally to the inner cavity of the corresponding end of the PVC film roll 4. In this embodiment, a longitudinal driving device 6 connected to the top end of the suspension rod 5 is arranged on the floating plate 14, and the controller 18 is connected to the longitudinal driving device 6 to realize the longitudinal movement control of the suspension rod 5, and drive the pressure rollers 13 on both sides to facilitate the insertion of the two ends of the PVC film roll 4.

[0025] In this embodiment, the longitudinal drive device 6 adopts a cylinder or an electric telescopic rod, which is flexible. The floating plate 14 is provided with guide rods 19 on both sides thereof, which longitudinally penetrate the corresponding suspension rod 5, and the suspension rod 5 is provided with guide holes corresponding to the guide rods 19, which improves the longitudinal movement stability of the suspension rod 5.

[0026] When the PVC film roll 4 is driven to rotate by the first driving roller 11 and the second driving roller 12, the pressure roller 13 is inserted into both ends of the PVC film roll 4 to apply pressure during the PVC film winding process, ensuring that the PVC film on the PVC film roll 4 is in close contact with the first driving roller 11 and the second driving roller 12 to avoid slipping and ensure the tightness of the winding.

[0027] A spacing sensor 15 pointing downward to the PVC film roll 4 is provided at the bottom of the floating plate 14 to detect the thickness of the PVC film rolled on the PVC film roll 4, which is beneficial to adjusting the height of the pressure roller 13. The spacing sensor 15 is connected to the controller 18 for signal transmission, and the controller 18 controls the lifting drive device 8 to change the position height of the floating plate 14, thereby changing the height of the pressure roller 13 and the pressure of the pressure roller 13 on the PVC film roll 4.

[0028] After winding is completed, unloading is required. At this time, the floating plate 14 is first raised by the lifting drive device 8, and the rise of the pressure roller 13 drives the rise of the PVC film roll 4, so that the PVC film is separated from the first drive roller 11 and the second drive roller 12, thereby improving the convenience of unloading.

[0029] like Figure 2 As shown, slide rails 3 located below both sides of the gantry 10 are horizontally arranged on the frame 1, and sliders 2 located on the corresponding slide rails 3 are arranged at the bottom of both sides of the gantry 10. After the PVC film roll 4 rises, the gantry 10 can be manually pushed to move the PVC film roll 4 forward, so that the PVC film roll 4 can be placed on a forklift or a conveyor belt for subsequent transfer. Finally, the suspension rod 5 moves outward longitudinally, driving the pressure rollers 13 to detach from the two ends of the PVC film roll 4, and a new PVC film roll is replaced to rewind it.
