Description

Technical Field

[0001] This utility model relates to the field of calendering technology, specifically to a calendering device. Background Technology

[0002] Film calendering equipment is an industrial device used to produce plastic films and other plastic products. It uses a series of parallel rollers rotating in opposite directions to extrude and stretch materials close to their viscous flow temperature, forming thin sheet products with a certain thickness and width.

[0003] For example, a calendering apparatus according to Chinese patent application number CN201621356489.7 includes a calendering unit and a take-up unit. The calendering unit is used to stretch the film, and the take-up unit is arranged adjacent to the calendering unit for pulling the film. The take-up unit includes a take-up roller with a granular anti-stick layer on its surface. The take-up roller contacts the film through the granular anti-stick layer. In use, after the film is calendered in the calendering unit, it is pulled away from the calendering unit by the take-up unit. Because the take-up roller contacts the film through the granular anti-stick layer, there is a gap between the granular anti-stick layer and the film, thereby reducing the contact area between the roller surface and the film. Part of the air is sealed within the contact surface, ensuring smooth film release from the roller and enabling the take-up roller to smoothly pull the film.

[0004] However, in actual use, after the above-mentioned device presses the film, it is directly wound up through the discharge port. The film is wound up before it has cooled down, which can easily lead to deformation and thus affect the overall quality of the film. Utility Model Content

Both the slid grooves and the threaded grooves are located at the bottom of the U-shaped fixed frame. Sliding plates are slidably provided inside the two slid grooves to facilitate the sliding plates to move up and down inside the slid grooves.

[0012] Preferably, a second rotating rod is fixed between the front and rear walls and between the two sliding plates on the other side of the U-shaped fixing frame, and a pressure roller is fixed on each of the two second rotating rods to facilitate calendering of the film to different thicknesses.

[0013] Preferably, the two sliding plates are threaded with bolts through threaded grooves on the opposite sides of each other, for fixing the sliding plates and the calender body, so as to facilitate unscrewing the bolts and adjusting the position of the sliding plates.

[0029] like Figure 1-7 As shown, this utility model provides a calendering device, including a calendering machine body 1. Mounting plates 9 are connected to the inner walls of both the front and rear sides of the calendering machine body 1 via bearings. A common take-up shaft 10 is detachably connected between the two mounting plates 9. A motor 12 is fixedly mounted on the rear wall of the calendering machine body 1. The output shaft of the motor 12 passes through the calendering machine body 1 and is fixedly connected to the rear mounting plate 9, facilitating the motor 12 to drive the mounting plate 9 to rotate the take-up shaft 10. A transparent observation window 7 is embedded in the front of the calendering machine body 1. Support columns 8 are fixedly mounted at the four corners of the bottom of the calendering machine body 1, facilitating the movement of this utility model.

[0030] like Figure 1-3As shown in Figures 5, 6, and 7, a pressing assembly 2 is provided on one side of the calender body 1 for pressing films of different thicknesses. The pressing assembly 2 includes a U-shaped fixing frame 21, which is fixedly mounted on one side of the calender body 1. A first rotating rod 22 is fixedly mounted on one side of the bottom of the U-shaped fixing frame 21. A heating roller 23 is rotatably mounted on the first rotating rod 22. Two sliding grooves 5 are provided on one side of the calender body 1. Threaded grooves 6 are provided on both the front and rear side walls of the calender body 1, and both the sliding grooves 5 and the threaded grooves 6 are located at the bottom of the U-shaped fixing frame 21.

[0031] Sliding plates 24 are slidably installed inside both of the two chute 5, which facilitates the up-and-down movement of the sliding plates 24 inside the chute 5. Second rotating rods 25 are fixed between the front and rear walls on the other side of the U-shaped fixing frame 21 and between the two sliding plates 24. Pressing rollers 26 are fixed on both of the second rotating rods 25, which facilitates calendering the film to different thicknesses. Bolts 27 that penetrate the threaded groove 6 are threadedly connected to the side of the two sliding plates 24 that are far apart from each other, which are used to fix the sliding plates 24 and the calender body 1, and facilitate unscrewing the bolts 27 to adjust the position of the sliding plates 24.

[0032] like Figure 1-4 As shown, a cooling assembly 3 is fixedly provided on the top of the calender body 1 for rapid cooling of the heated and pressed film. The cooling assembly 3 includes a blower 31, which is fixedly provided on the top of the calender body 1. A rotating shaft 35 is connected between the inner walls of the front and rear sides of the top of the calender body 1 through a bearing. A control panel 4 for controlling the operation of the blower 31 and the motor 12 is fixedly provided at one end of the front side of the calender body 1.

[0033] By setting up the clamping assembly 2, firstly, according to the thickness requirement of the film to be clamped, unscrew the bolts 27 on the two sliding plates 24, manually push the two bolts 27 to slide up and down along the two sliding grooves 5 respectively, so as to adjust the distance between the two clamping rollers 26 to adapt to clamping films of different thicknesses.
