[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, refer to Figure 1 and Figure 3A calender for PVC film production includes a base 1. Side seats 2 and 3 are welded to both ends of the top outer wall of the base 1. A handwheel 4 is rotatably connected to one side outer wall of side seat 2, and a bevel gear 5 is fixedly connected to one end outer wall of the handwheel 4. A bevel gear 6 meshes with the outer wall of bevel gear 5, and a lead screw 7 is fixedly connected to the inner wall of bevel gear 6. An end plate 8 is screwed to the outer wall of the lead screw 7, and a servo motor 9 is fixedly connected to the top outer wall of the end plate 8. The output shaft of the servo motor 9 is fixedly connected to a calendering roller 10 through a coupling.

[0022] In this embodiment, with the meshing of the two bevel gears, the handwheel 4 can be rotated to drive the calendering roller 10 to rise and fall, thus achieving precise adjustment of the height of the calendering roller 10. As the servo motor 9 drives the calendering roller 10 to rotate, the corresponding calendering operation can be completed. It is economical, durable, low in cost, and easy to maintain.

[0023] Example 2, refer to Figure 2 A calender for producing PVC film, wherein a curved plate 11 is welded to the top outer wall of side seat 2 3, and a fixed column 12 is fixedly connected to the inner wall of the curved plate 11, and an unwinding roller 13 is rotatably connected to the outer wall of the fixed column 12; a clamping seat 14 is welded to the top outer wall of side seat 2, and a fastening knob 15 is screwed to the top inner wall of the clamping seat 14.

[0024] In this embodiment, the unwinding roller 13 can rotate around the center of the fixed column 12. The wound PVC film only needs to be put onto the unwinding roller 13 and then slid into the unwinding roller 13 by rotating the fastening knob 15 to achieve the positioning of the PVC film. The operation is simple, quick and convenient.

[0025] Reference Figure 3 One end of the calender roll 10 is rotatably connected to an end plate 16, and a laser rangefinder 17 is fixedly connected to the inner wall of the end plate 16.

[0027] Reference Figure 1 and Figure 3 A controller 19 is installed on the top of the outer wall of one side of the side seat 2 3, and the controller 19 is connected to the laser rangefinder 17 by an electrical signal.

[0028] Refer to Figure 1-2 A guide roller 20 is rotatably connected between side seat 1 2 and side seat 2 3.

[0029] Reference Figure 2 The outer wall of one end of the fastening knob 15 is slidably connected to the inner wall of one end of the unwinding roller 13.

[0030] Working principle: First, the PVC film to be calendered is placed onto the unwinding roller 13. Then, the unwinding roller 13 is rotated into the holder 14 and fixed by rotating the fastening knob 15. After that, the PVC film will pass through the calendering roller 10 along the guide tube. When adjusting the height of the calendering roller 10, the meshing of bevel gear 5 and bevel gear 6 is used to drive the calendering roller 10 to rise and fall by rotating the handwheel 4, thereby matching the thickness of the PVC film. As the servo motor 9 drives the calendering roller 10 to rotate, the corresponding calendering operation can be completed.
