[0017] As Figures 1 - 3As shown, the surface treatment mechanism in this PVC film calender is arranged between the calendering mechanism 10 and the cooling mechanism 20. The calendering mechanism 10 has a frame 11 and an operating table 12. There is a guardrail 13 on the operating table 12. Both the calendering mechanism 10 and the cooling mechanism 20 adopt existing structures. The surface treatment mechanism includes a bracket 33, a embossing roller 39, a supporting roller 37 and a protective plate 42. The bracket 33 is connected to the frame 11. The embossing roller 39 and the supporting roller 37 are both horizontally rotatably arranged on the bracket 33, and the embossing roller 39 is arranged directly above the supporting roller 37. In this embodiment, the cooperation of the embossing roller 39 and the supporting roller 37 to realize the embossing treatment on the surface of the PVC film adopts existing technology. One end of the protective plate 42 is hinged to the operating table 12 through a hinge 44. There is a mounting seat 43 installed on the guardrail 13. A rotating shaft 49 is horizontally rotatably connected to the mounting seat 43. There is a winding and unwinding wheel 47 on the rotating shaft 49. One end of a steel wire rope 46 is connected to the winding and unwinding wheel 47, and the other end of the steel wire rope 46 is connected to the other end of the protective plate 42. A handle 51 is installed on the rotating shaft 49. A ratchet wheel 50 is also fixed on the rotating shaft 49. A pawl 48 is provided on the mounting seat 43, and the pawl 48 cooperates with the ratchet wheel 50. With this structure, by driving the rotating shaft 49 to rotate through the handle 51, the steel wire rope 46 can be wound in or unwound, so as to change the state of the protective plate 42. When it is necessary to lower the anti-slip plate downward, by releasing the pawl 48 and rotating the handle 51, finally the protective plate 42 can be lowered and presented at a certain slope. At this time, the elastic limiting pad 45 will abut against the operating table 12.

The upper slider 31 is connected to an upper connecting seat 40. The embossing roller 39 is horizontally rotatably connected to the upper connecting seat 40. A lower slider 34 is slidably connected to the lower guide rail 35. The lower slider 34 is connected to a lower connecting seat 38. The supporting roller 37 is horizontally rotatably connected to the lower connecting seat 38. A cylinder one 41 and a cylinder two 36 are also installed on the bracket 33. The piston rod end of the cylinder one 41 is connected to the upper connecting seat 40, and the piston rod end of the cylinder two 36 is connected to the lower connecting seat 38. With this structure, by the actions of the cylinder one 41 and the cylinder two 36, the upper connecting seat 40 and the lower connecting seat 38 can be made to move, so that the embossing roller 39 and the supporting roller 37 approach or move away from each other.

[0020] A cross bar 52 is also installed on the mounting seat 43, and the cross bar 52 is located above the winding and unwinding wheel 47. There is also a limiting ring 53 on the cross bar 52 that cooperates with the steel wire rope 46.
