DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To describe the technical content, structural features, achieved objectives and effects of the application in detail, the following will describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments can also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shapes, structures and characteristics of the exemplary embodiments can be used or implemented in another exemplary embodiment.

[0021] An embodiment of the present application provides a calendering device. As Figure 1 shown, the calendering device 100 is installed on the front side of the traction device 200. The traction device 200 tightens the product on the rear side of the calendering device 100 to ensure the flatness of the product, and the calendering device 100 is located downstream of the extrusion die 300 to receive the product extruded by the extrusion die 300.

[0022] As Figure 1 , 2 shown, the calendering device 100 includes a frame 1, a plurality of rollers 2 rotatably installed on the frame 1, a guide rail 3 arranged on the ground, a moving mechanism 4 installed at the bottom of the frame 1, and a backstop mechanism 5 located on the front side of the frame 1.

[0023] The frame 1 includes a pair of side walls 11 arranged opposite to each other left and right. A plurality of rollers 2 are rotatably installed between the pair of side walls 11. Each roller 2 extends along the left-right direction, and a plurality of rollers 2 are arranged in sequence from front to back on the frame 1. In the embodiment of the present application, the calendering device 100 includes three rollers.

[0024] The guide rail 3 on the ground extends in the front-rear direction. The frame 1 moves back and forth along the guide rail 3 through the moving mechanism 4. The moving mechanism 4 includes a plurality of moving wheels 41 and a moving motor 42 for driving the plurality of moving wheels 41 to rotate. The plurality of moving wheels 41 are rotatably installed at the bottom of the frame 1. Each moving wheel 41 cooperates with the guide rail 3 to be able to roll back and forth along the guide rail 3. The moving motor 42 drives the moving wheels 41 to rotate to drive the frame 1 and the rollers 2 on the frame 1 to move along the guide rail.

[0025] As Figure 3 , 4As shown in the figure, the anti-reverse mechanism 5 includes an anti-reverse lock plate 51, a locking screw rod 52, a mounting seat 53, a pin shaft 54, and a pair of locking nuts 55. The anti-reverse lock plate 51 is mounted on the guide rail 3. The mounting seat 53 is fixedly installed on the wheel frame 411 of the foremost moving wheel 41. One end of the locking screw rod 52 is rotatably connected to the mounting seat 53 through the pin shaft 54. The locking screw rod 52 has a locking position on the mounting seat 53 that cooperates with the anti-reverse lock plate 51 and an unlocking position where it withdraws from the anti-reverse lock plate 51. When the locking screw rod 52 is in the locking position, the machine frame 1 is fixedly connected to the guide rail 3 through the anti-reverse mechanism 5, and the machine frame 1 cannot move back and forth along the guide rail 3 through the moving mechanism 4. When the locking screw rod 52 is in the unlocking position, the machine frame 1 can move back and forth along the guide rail 3 through the moving mechanism 4. In the embodiment of the present application, the anti-reverse lock plate 51 is welded to the guide rail 3, and the pin shaft 54 extends in the up and down direction.

[0026] An anti-reverse groove 511 that penetrates the anti-reverse lock plate 51 from front to back is formed on the anti-reverse lock plate 51. The anti-reverse groove 511 can accommodate at least part of the locking screw rod 52. The anti-reverse groove 511 has an opening 5110 on the surface of the anti-reverse lock plate 51 for the locking screw rod 52 to move into and out of the anti-reverse groove 511. Since the locking screw rod 52 rotates around the pin shaft 54 extending in the up and down direction, the opening 5110 is formed on the side surface of the anti-reverse lock plate 51.

[0027] In the radial direction of the locking screw rod 52, the anti-reverse groove 511 has a groove width w that is larger than the diameter of the locking screw rod 52, so that the anti-reverse groove 511 can accommodate part of the locking screw rod 52; the width of the opening 5110 is equal to the groove width w.

[0028] A pair of locking nuts 55 are coaxially sleeved on the locking screw rod 52 and are threadedly connected to the locking screw rod 52. When the locking nuts 55 are rotated, the locking nuts 55 can move back and forth along the locking screw rod 52. The across flats dimension s of each locking nut 55 is larger than the groove width w of the anti-reverse groove 511. When the locking screw rod 52 is in the locking position, the pair of locking nuts 55 are respectively located on the front side and the rear side of the anti-reverse lock plate 51. The pair of locking nuts 55 are tightened so that the locking screw rod 52 is fixed on the anti-reverse lock plate 51. The pair of locking nuts 55 abut against the front side and the rear side of the anti-reverse lock plate 51 to prevent the machine frame 1 from moving back and forth.

[0029] When it is necessary to disconnect the machine frame 1 from the guide rail 3, the pair of locking nuts 55 are loosened, and then the locking screw rod 52 is rotated from the locking position to the unlocking position so that the locking screw rod 52 withdraws from the anti-reverse groove 511 of the anti-reverse lock plate 51. The machine frame 1 is unlocked from the guide rail 3 and can move back and forth along the guide rail 3 through the moving mechanism 4.

[0030] The foregoing has shown and described the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements. The scope of protection claimed by the present application is defined by the appended claims, the specification and their equivalents.
