Technical Field
[0001] This utility model relates to the field of flattening devices, and in particular to a plastic film flattening device. Background Technology
[0002] In modern industrial production, plastic film, as an important packaging material and industrial raw material, is widely used in many fields such as food, electronics, and chemicals. In the production process of plastic film, the flattening process is a crucial step in ensuring its quality and performance. A flat plastic film not only guarantees the aesthetics and airtightness of the packaging but also meets the stringent requirements of the electronics and chemical industries for material flatness and cleanliness.
[0003] Currently, in the production process of plastic film, the equipment used to transport the plastic film typically employs a relatively simple mechanical structure, such as a roller conveyor. Its technical principle mainly involves a motor driving the rollers to rotate, utilizing the friction between the rollers and the plastic film to transport the film along the production line.
[0004] However, these traditional cleaning methods have certain problems. Due to the complex operating environment during transportation, dust and other impurities easily adhere to the surface of plastic films. Existing simple cleaning methods cannot effectively remove these adhering impurities. This results in dust and impurities becoming trapped between the plastic films during the subsequent flattening process, severely affecting the flattening effect. Consequently, the flattened plastic film surface exhibits unevenness and defects, reducing product quality, increasing the defect rate, and ultimately impacting production efficiency and the company's economic benefits. Therefore, a plastic film flattening device is proposed to solve these problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 3 An embodiment of this utility model is provided: a plastic film flattening device, including a machine tool 1, a fixed frame 3 fixedly connected to the top of the machine tool 1, a flattening roller 4 rotatably connected inside the fixed frame 3, and a limit component and a cleaning component provided on the top of the machine tool 1;
[0033] The cleaning assembly includes a cleaning plate 24, which is located on the top of the machine tool 1. A fixing frame 3 is fixedly connected to the outer wall of the fixing frame 3. Multiple round bars 18 are fixedly connected to one side of the fixing frame 3. A slide block 19 is slidably connected to the outer wall of the fixing frame 3. A slider 22 is slidably connected inside the slide block 19. The slider 22 is slidably connected to the inner wall of the slide block 19. A motor 21 is fixedly connected inside the slider 22. A gear 20 is fixedly connected to the output end of the motor 21. The gear 20 meshes with the round bars 18. A connecting plate 23 is fixedly connected to the bottom of the slide block 19. The bottom of the connecting plate 23 is fixedly connected to the top of the cleaning plate 24.
[0034] Specifically, during the cleaning process of the plastic film surface, motor 21 is first started to drive gear 20 at its output end to rotate on the outer wall of the circular bar 18. As gear 20 rotates, slide 19 is pushed to slide on the outer wall of the fixed frame 17. When gear 20 moves to both sides of the circular bar 18, it smoothly transfers from one side to the other, while simultaneously pushing slider 22 to slide inside slide 19. Thus, slide 19 can achieve reciprocating linear motion. During the movement of slide 19, connecting plate 23 transmits this motion to cleaning plate 24, enabling it to effectively clean the top of the plastic film. The purpose of this operation is to prevent particles on the surface of the plastic film from affecting the subsequent flattening effect. This cleaning mechanism ensures that the surface of the plastic film remains clean, enhancing the flattening effect of the equipment on the plastic film.
[0035] Reference Figure 1 and Figure 2The limiting assembly includes multiple rubber rollers 14, which are located on the top of the machine tool 1. A conveyor belt 2 is rotatably connected inside the machine tool 1. Fixed frames 2 5 are fixedly connected to both sides of the top of the machine tool 1. Telescopic cylinders 6 are fixedly connected to both sides of the top of each fixed frame 2 5. A connecting frame 1 7 is fixedly connected to the output end of the telescopic cylinder 6. The connecting frame 1 7 is slidably connected to the inner wall of the fixed frame 2 5. Electric telescopic rods 8 are fixedly connected to both sides inside each connecting frame 1 7. A connecting block 1 9 is fixedly connected to the output end of each electric telescopic rod 8. Each connecting block 1 9 has a connecting block 1 9 on each side. Each outer wall is fixedly connected to a sliding plate 10. Each sliding plate 10 is slidably connected to the inside of the connecting frame 1 7. Each sliding plate 10 has multiple sliding grooves 15 inside. Each inner wall of the connecting frame 1 7 is fixedly connected to a limiting post 11. Each limiting post 11 is slidably connected to a connecting block 2 12 on its outer wall. Each connecting block 2 12 is fixedly connected to a connecting frame 2 13 at its bottom. Each connecting frame 2 13 is rotatably connected to the outer wall of the rubber roller 14. Each connecting block 2 12 is fixedly connected to a sliding strip 16 on one side. The sliding strip 16 is slidably connected to the inner wall of the sliding groove 15.
[0036] Specifically, during the movement of the plastic film, the electric telescopic rod 8 is first activated to drive the slide plate 10 on one side of the connecting block 9 to slide on the inner wall of the connecting frame 7. This process utilizes the design of the groove 15 to allow the connecting blocks 12 at one end of multiple slide bars 16 to move synchronously on the outer wall of the limiting post 11. The purpose of this mechanism is to evenly distribute the rubber rollers 14 on the top of the plastic film according to the different lengths of the plastic film, thus laying the foundation for the subsequent extrusion process. The even distribution of the rubber rollers 14 ensures that the downward extrusion force applied to them can act evenly on the surface of the plastic film. Subsequently, the telescopic cylinder 6 is activated, using its output end to drive the connecting frame 7 to slide on the inner wall of the fixed frame 5 until the rubber rollers 14 are moved to the top position of the plastic film. In this stage, the rubber rollers 14, through their downward extrusion force and their inherent high friction characteristics, effectively limit the direction of movement of the plastic film, effectively preventing the plastic film from shifting during movement and greatly enhancing the stability of the plastic film during movement. This stability not only improves the reliability of operation, but also ensures the smooth progress of subsequent processes.
[0037] Working principle: During the movement of the plastic film, the electric telescopic rod 8 is activated. The output end of the electric telescopic rod 8 drives the slide plate 10 on one side of the connecting block 9 to slide on the inner wall of the connecting frame 7. The sliding groove 15 drives the connecting block 12 at one end of multiple sliding strips 16 to move synchronously on the outer wall of the limiting post 11. Thus, according to the different lengths of the plastic film, the rubber rollers 14 are evenly distributed on the top of the plastic film, which facilitates the even distribution of the downward pressing force of the rubber rollers 14 on the surface of the plastic film. Next, the telescopic cylinder 6 is activated. The output end of the telescopic cylinder 6 drives the connecting frame 7 to slide on the inner wall of the fixed frame 5 until the rubber rollers 14 are moved to the top of the plastic film. The downward pressing force of the rubber rollers 14 and their high friction characteristics limit the movement direction of the plastic film, preventing the plastic film from deviating during the movement and enhancing the stability of the plastic film during the movement.
[0038] During the cleaning process of the plastic film surface, the motor 21 is started, and the output end of the motor 21 drives the gear 20 to rotate on the outer wall of the circular bar 18, thereby pushing the slide 19 to slide on the outer wall of the fixed frame 17. When the gear 20 moves to both sides of the circular bar 18, the gear 20 will move from one side of the circular bar 18 to the other side, and push the slider 22 to slide inside the slide 19. In this way, the slide 19 can achieve the left and right reciprocating linear motion. While the slide 19 is moving, it will drive the cleaning plate 24 to clean the top of the plastic film through the connecting plate 23, so as to prevent the presence of particles on the top of the plastic film, which may affect the subsequent flattening effect and enhance the flattening effect of the equipment on the plastic film.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
