Description

Technical Field

[0001] This utility model specifically relates to the field of thin film processing technology, and more specifically to a folding mechanism for a cutting and folding film machine. Background Technology

[0002] A cutting and folding film machine is a device used to cut and fold various film materials. It is widely used in packaging, printing, electronics, daily chemicals and other industries. The cutting and folding film machine uses a motor to drive a cutter or blade to cut the film material according to the preset size and shape. It uses a robotic arm, cylinder, adsorption robotic arm or folding plate and other devices to fold the film cloth precisely according to the set folding method, such as bifold, Z-fold, trifold, etc.

[0003] However, in practice, it has been noted that most cutting machines currently cut the film first and then use mechanical grippers to fold it. Due to the elasticity of the film, the folded film is prone to rebound, which affects the folding position and thus the folding effect. Utility Model Content

[0004] The purpose of this invention is to provide a folding mechanism for a cutting and folding film machine. This mechanism uses a spiral guide to bend and fold the film edge, and then a compression spring applies downward pressure to a moving slider. This pressure is applied to the film edge by a pressing roller at the bottom of the slider, preventing springback and improving the folding effect. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A folding mechanism for a film cutting and folding machine includes a film cutting machine, an end of which is fixedly connected to a support platform, and rectangular slide grooves are formed in a rectangular array on the support platform;

[0007] A film edge guide frame is symmetrically and movably connected above the support platform, and an edge extrusion roller is movably connected to one end of each film edge guide frame near the film cutting machine.

[0008] The film edge guide frame includes side baffles, each of which has an integrally formed spiral guide surface on its side, and the end of the side baffle has a storage groove for placing the edge extrusion wheel.

[0009] As a further technical solution of this utility model, the bottom of the side baffle is respectively fixedly connected with symmetrically arranged light hole sliders and threaded hole sliders, and the light hole sliders and threaded hole sliders respectively extend through the rectangular slide groove to the bottom of the support platform.

[0010] As a further technical solution of this utility model, the bottom of the support platform is provided with a sliding column that is symmetrically and fixedly connected to the support platform and a compound threaded screw that is movably connected to the support platform, and the compound threaded screw and the sliding column respectively pass through the threaded hole slider and the smooth hole slider.

[0011] As a further technical solution of this utility model, the compound threaded screw is threadedly engaged with the threaded hole slider, while the smooth hole slider is slidably engaged with the sliding column. A gearbox is also fixedly connected to the side of the film cutting machine. One end of the gearbox is drivenly engaged with the end of the compound threaded screw, while the other end of the gearbox is drivenly connected to a drive motor.

[0012] As a further technical solution of this utility model, the edge extrusion wheel includes a positioning post fixedly connected to the upper part of the storage groove, and a movable slider is movably connected to the lower part of the positioning post, wherein the positioning post is arranged in a rectangular array.

[0013] The movable slider has a circular groove corresponding to the positioning post, and the positioning post slides in conjunction with the circular groove.

[0014] As a further technical solution of this utility model, each of the circular grooves has a limiting slide groove on both sides, and each of the positioning pins is fixedly connected to a positioning rod at its end, with both ends of the positioning rod slidingly engaged with the limiting slide groove.

[0015] As a further technical solution of this utility model, a compression spring is fixedly connected to the bottom of the positioning column, and the compression spring is located at the bottom of the inner side of the circular groove. A squeezing roller is movably fitted to the bottom of the movable slider.

[0016] As a further technical solution of this utility model, the top of the film cutting machine is equipped with a top guide frame and a straight module, and the straight module is located on the side of the top guide frame away from the support platform. The side of the straight module is fixedly connected to a cutter.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes the threaded engagement between a compound threaded screw and a threaded hole slider to bring symmetrically arranged side baffles closer together or further apart, thus adjusting for the width of the film. The two ends of the film are guided by a spiral guide surface and folded, resulting in a bidirectional fold at the film's edges. After being guided by a top guide frame, the film is then compressed to ensure a proper folding effect. Furthermore, the elasticity of a compression spring applies downward pressure to the moving slider, compressing the folded film edges. A compression roller at the bottom of the moving slider guides the film edges, preventing springback after folding. A positioning post on the moving slider slides into a circular groove, providing a limiting effect. Finally, a horizontally positioned positioning rod is fixedly connected to the bottom of the positioning post, and both ends of the positioning post slide into limiting grooves on both sides of the moving slider, preventing slippage at the connection between the positioning post and the moving slider.

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.

[0030] Please see Figure 1-8 This utility model provides a folding mechanism for a film cutting and folding machine, including a film cutting machine 1, a support platform 2 fixedly connected to the end of the film cutting machine 1, and rectangular slide grooves 8 arranged in a rectangular array on the support platform 2.

[0031] A film edge guide frame 3 is symmetrically and movably connected above the support platform 2. Each of the film edge guide frames 3 is movably connected to an edge extrusion roller 9 at one end near the film cutting machine 1.

[0032] The film edge guide frame 3 includes a side baffle 31. Each side baffle 31 has an integrally formed spiral guide surface 33 on its side, and the end of the side baffle 31 has a storage groove 32 for placing the edge extrusion wheel 9.

[0033] Furthermore, the bottom of the side baffle 31 is respectively fixedly connected with symmetrically arranged light hole sliders 34 and threaded hole sliders 35, and the light hole sliders 34 and threaded hole sliders 35 extend through the rectangular slide grooves 8 to the bottom of the support platform 2.

[0034] By adopting the above technical solution, the threaded engagement between the compound threaded screw 10 and the threaded hole slider 35 causes the symmetrically arranged side baffles 31 to move closer or further apart, thereby adjusting according to the width of the film. The two ends of the film are folded after being guided by the spiral guide surface 33, and the edges of the film are folded in both directions. After being guided by the top guide frame 5, the film is squeezed to ensure the folding effect.

[0035] Furthermore, the bottom of the support platform 2 is provided with a sliding column 11 that is symmetrically and fixedly connected to the support platform 2 and a compound threaded screw 10 that is movably connected to the support platform 2, and the compound threaded screw 10 and the sliding column 11 respectively pass through the threaded hole slider 35 and the smooth hole slider 34.

[0036] More specifically, the compound threaded lead screw 10 is threadedly engaged with the threaded hole slider 35, while the smooth hole slider 34 is slidably engaged with the sliding column 11. The side of the film cutting machine 1 is also fixedly connected to a gearbox 4, wherein one end of the gearbox 4 is drivenly engaged with the end of the compound threaded lead screw 10, and the other end of the gearbox 4 is drivenly connected to a drive motor.

[0037] Furthermore, the edge extrusion wheel 9 includes a positioning post 94 fixedly connected to the upper part of the receiving groove 32, and a movable slider 91 is movably connected to the lower part of the positioning post 94. The positioning post 94 is arranged in a rectangular array.

[0038] The movable slider 91 has a circular groove 95 corresponding to the positioning post 94, and the positioning post 94 slides in conjunction with the circular groove 95.

[0039] Furthermore, each of the circular grooves 95 has a limiting groove 93 on both sides, and each of the positioning posts 94 has a positioning rod 96 fixedly connected to its end, with both ends of the positioning rod 96 slidingly engaging with the limiting groove 93.

[0040] More specifically, the bottom of the positioning post 94 is fixedly connected to a compression spring 97, and the compression spring 97 is located at the bottom of the inner side of the circular groove 95. The bottom of the movable slider 91 is movably fitted with a squeezing roller 92.

[0041] By adopting the above technical solution, the elasticity of the compression spring 97 applies downward pressure to the movable slider 91, thereby squeezing the edge of the folded film. The squeezing roller 92 at the bottom of the movable slider 91 guides the edge of the film to prevent the film edge from springing back after folding. Furthermore, the positioning post 94 on the movable slider 91 slides in conjunction with the circular groove 95, which can limit its movement.

[0042] Furthermore, the top of the film cutting machine 1 is equipped with a top guide frame 5 and a straight module 6, and the straight module 6 is located on the side of the top guide frame 5 away from the support platform 2, wherein a cutter 7 is fixedly connected to the side of the straight module 6.

[0043] By adopting the above technical solution, the bottom of the positioning post 94 is fixedly connected to a horizontally arranged positioning rod 96, and the two ends of the positioning post 94 are slidably engaged with the limiting grooves 93 on both sides of the movable slider 91, thereby preventing slippage at the connection between the positioning post 94 and the movable slider 91.

[0044] Furthermore, the bottom of the side baffle 31 and the bottom of the extrusion roller 92 are in contact with the support platform 2, and the linear module 6 can drive the cutter 7 to move. The end of the cutter 7 is provided with a cutting saw blade. The cutter 7 drives the cutting saw blade to rotate and cut the film.

[0045] The working principle of this utility model is as follows: When in use, the film is first placed from the right side of the support platform 2, and the edges of the film on both sides are folded inward after being guided by the spiral guide surface 33. The folded edges of the film pass the bottom of the edge extrusion roller 9, and the compression spring 97 applies a downward push to the moving slider 91 through its own elasticity. The extrusion roller 92 at the bottom of the moving slider 91 extrudes the folded edges of the film to prevent springback at the folded position, thereby improving the folding effect. The extrusion roller 92 also serves as a guide, allowing the film to pass through the bottom of the cutter 7 after passing around the top guide frame 5. The linear module 6 drives the cutter 7 to move back and forth to cut the film. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
