Description

Technical Field

[0001] The utility model relates to the technical field of PVC film processing, in particular to a leveling structure used for processing ultraviolet-resistant PVC films. Background Art

[0002] UV-resistant PVC film is a special PVC (polyvinyl chloride) material. UV-resistant PVC film is a polymer material with excellent UV resistance. It achieves UV resistance through specific preparation processes and additives, providing additional UV protection for the product and extending its service life.

[0003] The patent document with application number 202322764151.1 discloses a leveling structure of a PE shrink film production line. The utility model includes a leveling frame, a lower leveling roller is rotatably connected between the side walls of the leveling frame, an upper leveling roller is arranged above the lower leveling roller, two limit frames are arranged on the circumferential side sliding of the lower leveling roller, and self-adjusting mechanisms are arranged on both sides of the upper leveling roller. Each set of self-adjusting mechanisms includes an adjusting groove, a spring and a slider. The adjusting groove is opened on one side wall of the leveling frame, the spring is fixedly connected to the inner bottom wall of the adjusting groove, the slider is fixedly connected to the upper end of the spring, the upper leveling roller is rotatably connected to one side of the slider, and a lifting mechanism is arranged above the two sliders.

[0004] However, when the traditional leveling structure used for processing UV-resistant PVC film is used, a film cutter is used to cut the film after the winding length is reached, which easily causes wrinkles in the cutting position, resulting in uneven winding and poor use effect. For example, there are two types of UV-resistant PVC film: single-layer film and composite film. During the winding process of the composite film, bubbles are likely to appear between the composite films, and the PVC film needs to be leveled. In addition, during the cutting process, the film is likely to cause wrinkles at the cutting position, resulting in uneven film winding. Utility Model Content

[0005] The utility model discloses a leveling structure for processing UV-resistant PVC film, aiming to solve the technical problem that when a conventional leveling structure for processing UV-resistant PVC film is used, a film cutter is used to cut the film after the winding length is reached, which easily causes wrinkles in the film at the cutting position, resulting in uneven winding and poor use effect.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A leveling structure for processing UV-resistant PVC film, comprising a workbench and a UV-resistant PVC film body, and further comprising:

[0008] Flattening mechanism: the flattening mechanism is located on the workbench;

[0009] A gantry is provided on the outer walls on both sides of the workbench, first electric telescopic rods are provided on both sides of the inner wall at the top of the gantry, one end of the piston rods of the two first electric telescopic rods is connected to the same pressure plate, a mounting hole is opened on the top outer wall of the pressure plate, electric guide rails are provided on the inner walls on both sides of the mounting hole, a connecting block is provided on the inner walls of the two electric guide rails, a film cutter is provided on the inner wall of the connecting block, a limit block and a limit spring are respectively provided on the circumferential outer wall of the film cutter, the limit spring is located between the limit block and the connecting block, and a gasket is provided on the bottom outer wall of the pressure plate.

[0010] In this solution, a pressure plate is added at the cutting position to press down the UV-resistant PVC film body, so that the film cutter will not produce wrinkles when cutting the film. The first electric telescopic rod is driven to move the pressure plate downward to press down the UV-resistant PVC film body. When the film cutter contacts the film, the limit spring is compressed, so that the film cutter and the pressure plate are flush and aligned with the cutting position of the film. The connecting block is driven to move by the electric slide rail, so that the film cutter moves and cuts the film in the middle position of the pressure plate. The pressure plate cooperates with the gasket to press the film. The cutting process of the film cutter is smooth without causing wrinkles in the film. The subsequent winding is flat and the use effect is better.

[0011] In a preferred scheme, the flattening mechanism includes mounting blocks arranged on the outer walls on both sides of the workbench, mounting grooves are opened on the outer walls on opposite sides of the two mounting blocks, and sliders are slidably connected on the inner walls of the mounting grooves, and the same pressure roller is provided on the outer walls on opposite sides of the two sliders, and a return spring and a limit rod are respectively provided on the top outer walls of the sliders, and the limit rod is located inside the return spring, and the limit rod passes through one end of the mounting block and is connected to a limit ring, and the same connecting rod is connected between the two limit rings, and the same connecting frame is connected to the top outer walls of the two mounting blocks, and a second electric telescopic rod is provided on the top outer wall of the connecting frame, and one end of the piston rod of the second electric telescopic rod is connected to the bottom outer wall of the connecting rod.

[0012] By adopting the above technical scheme, the UV-resistant PVC film body of the composite film is prone to generate bubbles. The film is flattened by the position of the pressure roller so that the film is compacted without generating bubbles. According to the different thicknesses of the UV-resistant PVC film body, the second electric telescopic rod can be used to drive the connecting rod to pull the limit rings on both sides up and down, so that the slider moves up and down to squeeze the reset spring, driving the pressure roller to move to an appropriate position, thereby performing flattening work to make the UV-resistant PVC film body smoother.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the 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. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0022] The utility model discloses a leveling structure for processing UV-resistant PVC film, which is mainly applied to the conventional leveling structure for processing UV-resistant PVC film. When the leveling structure is used, after the winding length is reached, a film cutter is used to cut the film, which easily causes wrinkles in the film at the cutting position, resulting in uneven winding and poor use effect.

[0023] Reference Figure 1 , Figure 3 and Figure 4 A leveling structure for processing UV-resistant PVC film, comprising a workbench 1 and a UV-resistant PVC film body 2, and further comprising:

[0024] Flattening mechanism: The flattening mechanism is located on the workbench 1;

[0025] The same gantry 6 is fixedly connected to the outer walls on both sides of the workbench 1, and the first electric telescopic rods 9 are provided on both sides of the top inner wall of the gantry 6. One end of the piston rod of the two first electric telescopic rods 9 is fixedly connected to the same pressing plate 16, and a mounting hole 17 is opened on the top outer wall of the pressing plate 16. Electric guide rails are provided on the inner walls on both sides of the mounting hole 17. The same connecting block 19 is slidably connected to the inner walls of the two electric guide rails. A film cutter 18 is provided on the inner wall of the connecting block 19. Limit blocks and limit springs 20 are respectively provided on the circumferential outer walls of the film cutter 18. The limit spring 20 is located between the limit block and the connecting block 19, and a gasket 21 is provided on the bottom outer wall of the pressing plate 16.

[0026] During the specific working process, when the UV-resistant PVC film body 2 is cut, the first electric telescopic rod 9 works to drive the pressure plate 16 to move downward to press the UV-resistant PVC film body 2. The pressure plate 16 cooperates with the gasket 21 to press the film. When the film cutter 18 contacts the film, the limit spring 20 is compressed to make the blade position of the film cutter 18 flush with the pressure plate 16 and then align with the cutting position of the film. The connecting block 19 is driven to move by the electric slide rail, so that the film cutter 18 moves and cuts the film in the middle position of the pressure plate 16.

[0027] Among them, the pressing plate 16 and the film cutter 18 are both used in conjunction with the UV-resistant PVC film body 2. In this way, the pressing plate 16 presses the UV-resistant PVC film body 2, which is more conducive to the film cutter 18 to cut it. The two sides are pressed tightly, and the film cutter 18 cuts in the middle position, which will not cause wrinkles on the UV-resistant PVC film body 2 and makes the whole body smoother.

[0028] Among them, the gasket 21 is made of rubber material and is located at the bottom of the mounting hole 17. In this way, the rubber gasket 21 can be deformed and contact with the UV-resistant PVC film body 2 more closely. At the same time, it is located at the bottom of the mounting hole 17, so that the contact between the pressure plate 16 and the UV-resistant PVC film is more stable.

[0029] Reference Figure 1 and Figure 2 In a preferred embodiment, the flattening mechanism includes a mounting block 4 fixedly connected to the outer walls on both sides of the workbench 1, mounting grooves are opened on the outer walls on the opposite sides of the two mounting blocks 4, and a slider 10 is slidably connected to the inner wall of the mounting groove. The outer walls on the opposite sides of the two sliders 10 are provided with the same pressing roller 5, and the top outer walls of the sliders 10 are respectively provided with a reset spring 11 and a limit rod, the limit rod is located inside the reset spring 11, and the limit rod passes through one end of the mounting block 4 and is fixedly connected to a limit ring 12, and the same connecting rod 13 is fixedly connected between the two limit rings 12, and the top outer walls of the two mounting blocks 4 are fixedly connected to the same connecting frame 14, and the top outer wall of the connecting frame 14 is provided with a second electric telescopic rod 15, and one end of the piston rod of the second electric telescopic rod 15 is connected to the bottom outer wall of the connecting rod 13.

[0030] Specifically, when the UV-resistant PVC film body 2 is a composite film, bubbles will be generated between the films. The film is flattened by the position of the pressure roller 5 so that the film is compacted without generating bubbles. According to the different thicknesses of the UV-resistant PVC film body 2, the second electric telescopic rod 15 on the connecting frame 14 can be used to drive the connecting rod 13 to pull the limiting rings 12 on both sides to move up and down, so that the slider 10 moves up and down to squeeze the reset spring 11, and drives the pressure roller 5 to move to an adaptive position, thereby performing the flattening work.

[0031] The pressing roller 5 is used in conjunction with the UV-resistant PVC film body 2. Thus, the pressing roller 5 can rotate to continuously flatten the transported UV-resistant PVC film body 2, so that no bubbles are generated in the film and the film is flatter and tighter as a whole.

[0032] Reference Figure 1In a preferred embodiment, two fixing rods are fixedly connected to one side of the top outer wall of the workbench 1, and the same unwinding roller 3 is provided on the outer walls on the opposite sides of the two fixing rods. Two mounting rods are fixedly connected to the other side of the top outer wall of the workbench 1, and the same winding roller 8 is provided on the outer walls on the opposite sides of the two mounting rods. Vertical rods are fixedly connected to the outer walls on both sides of the workbench 1 close to the gantry 6, and the same transfer roller 7 is provided on the outer walls on the opposite sides of the two vertical rods. The UV-resistant PVC film body 2 is used in conjunction with the unwinding roller 3, the transfer roller 7 and the winding roller 8 respectively.

[0033] Specifically, the unwinding roller 3 unwinds the UV-resistant PVC film body 2, and after flattening and cutting, it is transferred by the transfer roller 7 to the winding roller 8 for winding. The overall coordination effect is good, which is convenient for subsequent transmission and use.

[0034] Working principle: When in use, after the unwinding roller 3 unwinds the UV-resistant PVC film body 2, it passes through the position of the pressing roller 5. The UV-resistant PVC film body 2 of different thicknesses can work through the second electric telescopic rod 15, driving the connecting rod 13 to pull the limit rings 12 on both sides to move up and down, so that the slider 10 moves up and down to squeeze the reset spring 11, driving the pressing roller 5 to move to the matching position, so that the pressing roller 5 flattens the UV-resistant PVC film body 2, and then passes through the gantry 6 position for cutting. At this time, the first The electric telescopic rod 9 works, driving the pressure plate 16 to move downward to press the UV-resistant PVC film body 2, and the gasket 21 cooperates to press tightly. When the film cutter 18 contacts the film, the limit spring 20 is compressed, so that the film cutter 18 is flush with the pressure plate 16 and aligned with the cutting position of the film. The connecting block 19 moves on the electric slide rail, thereby driving the film cutter 18 to move and cut the film in the middle position of the pressure plate 16 without wrinkles. The cut UV-resistant PVC film body 2 is transferred to the winding roller 8 through the transfer roller 7 for winding.

[0035] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
