Description

Technical Field

[0001] This utility model relates to the field of film cutting technology, and in particular to a film cutting mechanism. Background Technology

[0002] In the film processing industry, with the increasing market demand for film products and the ever-increasing requirements for product quality and production efficiency, film cutting, as a key process, makes the research and improvement of its related mechanisms crucial. Films are widely used in packaging, electronics, agriculture, and many other fields. Different fields have different requirements for the size, shape, and quality of films, necessitating efficient and precise film cutting mechanisms to meet diverse production needs. Traditional film cutting methods are relatively simple and crude, making them unsuitable for modern large-scale, high-precision production models. Therefore, developing new film cutting mechanisms has become an urgent need for the industry's development.

[0003] Currently, in existing film cutting technologies, the common mechanical structure uses a relatively fixed combination of a blade holder and cutting blades. A motor drives the blade holder in linear motion, and the sharp edge of the cutting blades cuts the film. The technical principle is mainly based on simple linear motion and cutting action; the motor's power is converted into the translation of the blade holder, thereby achieving film segmentation. Regarding the installation of the cutting blades, a fixed installation method is mostly used, that is, the cutting blades are firmly fixed to the blade holder using bolts or other connectors.

[0004] However, this traditional film cutting technology has a significant problem. Because the cutting blade is fixedly mounted, in actual production, when the blade wears out and needs replacement, operators need to spend a considerable amount of time disassembling and reassembling bolts and other connectors. Furthermore, during disassembly and reassembly, the blade's position must be carefully adjusted to ensure cutting accuracy. This series of cumbersome procedures leads to lengthy blade replacement times, severely impacting the overall efficiency of the film cutting process. Therefore, a film cutting mechanism is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a film cutting mechanism, which aims to improve the problem that in the prior art, the cutting blade is fixedly installed. In actual production, when the cutting blade is worn and needs to be replaced, the operator needs to spend a lot of time disassembling and installing bolts and other connecting parts, resulting in reduced work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A film cutting mechanism includes a winding device, a hydraulic cylinder fixedly connected to the side wall of the winding device, a second support plate fixedly connected to the output end of the hydraulic cylinder, a moving device fixedly connected to the top of the second support plate, a lifting device fixedly connected to the outer wall of the moving device, a knife holder fixedly connected to the bottom of the lifting device, and a quick-release assembly provided on the inner wall of the knife holder.

[0008] The quick-release assembly includes a hollow column, the outer wall of which is slidably connected to the inside of the tool holder. A threaded rod is threadedly connected to the inside of the hollow column. A turntable is fixedly connected to one end of the threaded rod. A spring is provided at one end of the threaded rod. One end of the spring is fixedly connected to one end of the threaded rod. A trapezoidal column is fixedly connected to the other end of the spring. The outer wall of the trapezoidal column is slidably connected to the inner wall of the hollow column. A retaining ball is provided on the outer wall of the trapezoidal column. The outer wall of the retaining ball is slidably connected to the inside of the hollow column. A blade assembly is provided on the inner wall of the tool holder.

[0009] As a further description of the above technical solution:

[0010] The blade assembly includes a cutting blade, the sidewall of which is disposed inside the blade holder, and the cutting blade is internally slidably connected to the outer wall of the hollow column;

[0011] As a further description of the above technical solution:

[0012] The second support plate is fixedly connected to the side wall of the first support plate, and the first support plate is fixedly connected to the side wall of the first support plate. Multiple rotating rollers are rotatably connected to the inner wall of the first support plate. The outer wall of the rotating rollers is provided with a second connecting plate. The side wall of the second connecting plate is rotatably connected to the first connecting plate. A screw is rotatably connected inside the first connecting plate. The outer wall of the screw is threadedly connected to the inside of the second connecting plate. A patterned roller is rotatably connected to the side wall of the first connecting plate.

[0013] As a further description of the above technical solution:

[0021] As a further description of the above technical solution:

[0022] One end of the fixed column is fixedly connected to a retaining ring, and the other end of the fixed column is fixedly connected to the side wall of the first support plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, rotating the turntable causes the threaded rod at one end to rotate under force. Subsequently, the rotation of the threaded rod causes the spring at one end to contract. The contraction of the spring causes the trapezoidal column on the side wall to slide on the inner wall of the hollow column. The movement of the trapezoidal column causes the ball on the outer wall to slide, achieving the effect of quickly disassembling the cutting blade. This solves the problem of long replacement time and low work efficiency when replacing fixed cutting blades, and improves the convenience of the film disassembly and cutting mechanism.

[0025] 2. In this utility model, the drive motor drives the rotating column to rotate, the rotation of the rotating column drives the first rotating plate to rotate, the rotation of the first rotating plate drives the second rotating plate on the side wall to rotate, and then the rotation of the second rotating plate drives the internal U-shaped plate to rotate, which achieves the effect of limiting the film. This solves the problem that the film cannot be limited and the position is offset during winding, thus causing the winding to be offset. This improves the practicality of the film cutting mechanism.

[0035] 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.

[0036] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides a film cutting mechanism, including a winding device 1, a hydraulic cylinder 3 fixedly connected to the side wall of the winding device 1, a second support plate 4 fixedly connected to the output end of the hydraulic cylinder 3, the second support plate 4 being made of stainless steel, which has good corrosion resistance and wear resistance, can adapt to different working environments, and ensures the accuracy and reliability of the device during long-term use. A moving device 5 is fixedly connected to the top of the second support plate 4, a lifting device 6 is fixedly connected to the outer wall of the moving device 5, a knife holder 27 is fixedly connected to the bottom of the lifting device 6, and a quick-release assembly is provided on the inner wall of the knife holder 27.

[0037] The quick-release assembly includes a hollow column 13, typically made of copper alloy, which offers excellent wear resistance and corrosion resistance. Its outer wall is slidably connected to the inside of the tool holder 27, allowing for smooth sliding within the tool holder 27 and preventing rust. A threaded rod 14 is threadedly connected inside the hollow column 13. The threaded rod 14 is made of medium carbon steel, which, after tempering, possesses high comprehensive mechanical properties and can withstand significant torque, ensuring stability during rotational adjustment. A turntable 12 is fixedly connected to one end of the threaded rod 14. The turntable 12 is made of rubber, providing excellent anti-slip properties for easy rotation and adjustment of the threaded rod 14. A spring 15 is installed at one end of the threaded rod 14, with one end fixedly connected to the other end. There is a trapezoidal column 17, which is made of wear-resistant alloy steel. It has high hardness and wear resistance, ensuring that it is not easily worn during relative sliding with the hollow column 13. The outer wall of the trapezoidal column 17 is slidably connected to the inner wall of the hollow column 13. A retaining ball 16 is provided on the outer wall of the trapezoidal column 17. The retaining ball 16 is usually made of bearing steel. Bearing steel has high hardness, wear resistance and contact fatigue strength, which can ensure that the retaining ball 16 maintains good performance in frequent locking and locking actions. The outer wall of the retaining ball 16 is slidably connected to the inside of the hollow column 13. The inner wall of the tool holder 27 is provided with a blade assembly, which includes a cutting blade 18. The cutting blade 18 is generally made of cemented carbide. Cemented carbide has the characteristics of high hardness, good wear resistance and strong heat resistance, which can efficiently cut films and ensure cutting quality and efficiency. The side wall of the cutting blade 18 is located inside the tool holder 27, and the inside of the cutting blade 18 is slidably connected to the outer wall of the hollow column 13.

[0038] Specifically, when disassembling the cutting blade 18, the disassembly process is first initiated by rotating the turntable 12. When the turntable 12 is subjected to applied force, it causes the threaded rod 14 on its side wall to rotate. The rotation of the threaded rod 14 pulls on a spring 15 at one end, causing it to contract. As the spring 15 contracts, it generates a reaction force, pushing a trapezoidal column 17 at one end to move along the inner wall of the hollow column 13. The movement of the trapezoidal column 17 further drives the retaining ball 16 on the outer wall to move accordingly. During this movement, the retaining ball 16 engages its outer wall inside the blade holder 27, thereby releasing the fixing of the cutting blade 18. Finally, by moving the hollow column 13, its outer wall is removed from the interior of the cutting blade 18, completing the rapid disassembly of the cutting blade 18. This not only simplifies the disassembly process but also improves the convenience and efficiency of operation, ensuring that the cutting blade 18 can be quickly and safely removed from the device.

[0039] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7A drive motor 19 is fixedly connected inside the first support plate 2. A rotating column 20 is fixedly connected to the output end of the drive motor 19. The rotating column 20 is generally made of steel. After appropriate heat treatment, the steel has good comprehensive mechanical properties, with moderate strength and toughness, which can meet the torque transmission requirements of the rotating column 20. A first rotating plate 21 is rotatably connected to the side wall of the rotating column 20. A second rotating plate 22 is rotatably connected to the side wall of the first rotating plate 21. The first rotating plate 21 and the second rotating plate 22 are usually made of aluminum alloy. Aluminum alloy is lightweight and has a certain strength, which can reduce the weight of the rotating parts while ensuring structural stability, making the rotation more flexible and reducing energy consumption. The inner U-shaped plate 23 is rotatably connected to the side wall. The inner U-shaped plate 23 is generally made of low carbon alloy steel. Low carbon alloy steel has good welding performance and certain strength, is easy to process and form, and can withstand certain external forces. The bottom of the inner U-shaped plate 23 is fixedly connected to a fixing rod 26. The side wall of the fixing rod 26 is fixedly connected to a sliding sleeve 29. The sliding sleeve 29 is usually made of copper alloy. Copper alloy has good wear resistance and self-lubricating properties, which makes the sliding sleeve 29 slide more smoothly on the fixing column 24 and reduces friction loss. The inner wall of the sliding sleeve 29 is slidably connected to the fixing column 24. One end of the fixing column 24 is fixedly connected to a retaining ring 25. One end of the fixing column 24 is fixedly connected to the side wall of the first support plate 2.

[0040] Specifically, when limiting the film, the output of the drive motor 19 first drives the rotating column 20 to rotate. The rotation of the rotating column 20 will cause the first rotating plate 21 on its side wall to rotate accordingly. During the rotation of the first rotating plate 21, it will drive the second rotating plate 22 on its side wall to rotate as well. The rotation of the second rotating plate 22 will further drive the internal U-shaped plate 23 on its side wall to rotate. During the movement of the internal U-shaped plate 23, it will drive the fixing rod 26 on its outer wall to move. The movement of the fixing rod 26 will drive the sliding sleeve 29 on one side to slide on the outer wall of the fixing column 24, thereby achieving effective limiting of the film, ensuring that the film maintains a stable position during processing, and improving production efficiency and product quality.

[0041] Reference Figure 3 and Figure 4The first support plate 2 is fixedly connected to the side wall of the second support plate 4. The distribution box 11 is fixedly connected to the side wall of the first support plate 2. Multiple rotating rollers 8 are rotatably connected to the inner wall of the first support plate 2. The rotating rollers 8 are usually made of seamless steel pipe. Seamless steel pipe has high strength and smooth surface, which can ensure stability and low friction during rotation, reducing damage to the film. The outer wall of the rotating rollers 8 is provided with a second connecting plate 28. The side wall of the second connecting plate 28 is rotatably connected to a first connecting plate 9. The first connecting plate 9 is similar to the second connecting plate 28 and is usually made of aluminum alloy to ensure the connection is lightweight and has a certain strength. The first connecting plate 9 is rotatably connected to a screw 10 inside. The outer wall of the screw 10 is threaded to the inside of the second connecting plate 28. The side wall of the first connecting plate 9 is rotatably connected to a patterned roller 7. The roller body of the patterned roller 7 is usually made of steel and the surface is treated with special patterns, such as chrome plating or engraving. The steel material ensures the strength of the roller body, and the chrome plating treatment can improve its wear resistance and corrosion resistance.

[0042] Specifically, the equipment is adjusted by turning the screw 10. Once the screw 10 is loosened, the first connecting plate 9 can be turned. The rotation of the first connecting plate 9 drives the patterned roller 7 on its side wall to rotate as well. During rotation, the outer wall of the patterned roller 7 tightly adheres to the outer wall of the rotating roller 8. This design allows the pattern on the patterned roller 7 to be accurately printed onto the film, achieving a printing effect that not only improves printing accuracy and efficiency but also ensures the clarity and consistency of the pattern, making it suitable for various film printing needs.

[0043] Working principle: When disassembling the cutting blade 18, first rotate the turntable 12. The turntable 12 is driven by force to rotate the threaded rod 14 on the side wall. Then, during the rotation of the threaded rod 14, it will cause the spring 15 at one end to retract. The retraction of the spring 15 will then cause the trapezoidal column 17 at one end to move to the inner wall of the hollow column 13. Subsequently, during the movement of the trapezoidal column 17, it will cause the retaining ball 16 on the outer wall to move. Then, during the movement of the retaining ball 16, it will lock the outer wall inside the blade holder 27. Then, it can drive the hollow column 13 to move its outer wall out of the interior of the cutting blade 18, thus achieving the effect of quickly disassembling the cutting blade 18.

[0044] Subsequently, when limiting the film, the rotating column 20 is first driven to rotate by the output end of the drive motor 19. Then, the rotation of the rotating column 20 causes the first rotating plate 21 of the side wall to rotate. Then, during the rotation of the first rotating plate 21, the second rotating plate 22 of the side wall is also driven to rotate. Then, the rotation of the second rotating plate 22 causes the inner U-shaped plate 23 of the side wall to rotate. Then, during the movement of the inner U-shaped plate 23, the fixing rod 26 of the outer wall is moved. Then, the movement of the fixing rod 26 causes the sliding sleeve 29 on one side to slide on the outer wall of the fixing column 24, thus achieving the effect of limiting the film.

[0045] Then, by turning the screw 10, the screw 10 will loosen, and the first connecting plate 9 can be turned to rotate. During the rotation of the first connecting plate 9, the patterned roller 7 on the side wall will be driven to rotate as well, and the outer wall of the patterned roller 7 will be attached to the outer wall of the rotating roller 8, thus achieving the effect of film printing.

[0046] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
