Description

Technical Field

[0001] This utility model relates to the field of asynchronous cutting mechanism technology, specifically to an asynchronous cutting mechanism for optical composite film processing. Background Technology

[0002] Optical composite films are multilayer film structures made of various thin film materials with different optical properties through processes such as lamination, coating, and compounding. They typically have multiple optical functions, such as reflection, transmission, polarization, brightness enhancement, and diffusion. They are widely used in display technology, optical imaging systems, lighting equipment, optical sensors, and other fields. They can effectively improve the performance of optical systems, enhance display effects, strengthen optical signals, or achieve specific optical functions. They are an indispensable key material in modern optics and display technology. The asynchronous cutting mechanism in optical composite film processing is a device used to cut optical composite films. Through a special mechanical structure and control method, the cutting tool and the optical composite film are fed at different speeds, thereby achieving a precise and efficient cutting effect. This mechanism can flexibly adjust the cutting parameters according to the characteristics, thickness, and size requirements of the optical composite film, which can effectively improve cutting accuracy and production efficiency, reduce material waste, and is widely used in the production process of optical composite films to meet the cutting needs of different products. In the processing of optical composite films, since their multi-layered structure is usually bonded together with adhesives, when the optical composite film is cut with a cutting tool, the adhesive at the edge can easily stick to the tool surface. This adhesion phenomenon may result in adhesive residue on the edge or hole edge of the cut optical composite film, affecting its appearance quality. At the same time, the accumulation of adhesive on the tool surface will reduce the cutting accuracy and efficiency, and may even lead to incomplete cutting or burrs. Therefore, to address the above problems, an asynchronous cutting mechanism for optical composite film processing is proposed. Utility Model Content

[0016] Please see Figure 1-8 This utility model provides a technical solution: An asynchronous cutting mechanism for processing optical composite films includes a worktable 1, a feeding roller 2, and a take-up roller 3. An arch frame 4 and a cutting assembly 5 are fixedly connected to the top of the worktable 1. A take-up assembly 6 is fixedly connected to one side of the arch frame 4, and a cleaning assembly 7 is fixedly connected to the outside of the take-up assembly 6. The take-up assembly 6 includes an electric telescopic rod 61, a take-up shell 62 is fixedly connected to one side of the electric telescopic rod 61, and a take-up groove 63 is formed inside the take-up shell 62. A disassembly mechanism is fixedly connected to the right side of the electric telescopic rod 61 by bolts. The unloading plate 64 and the cleaning component 7 include a folding plate 71. A shaft through hole 72 is opened on the inner side of the folding plate 71. A side block 73 is fixedly connected to one side of the folding plate 71. A cross frame 74 is fixedly connected to one side of the side block 73. A central column 75 is fixedly connected to one end of the cross frame 74 near the pawl 77. A spring 76 is fixedly connected to the outer side of the central column 75. A scraper 79 is opened on the inner side of the pawl 77. The scraper 79 is rotatably connected to the inner side of the shaft through hole 72. The left and right ends of the receiving shell 62 are fixedly connected to the folding plate 71.

[0017] As a further implementation of this solution, the cutting component 5 includes a column 51, with a top plate 52 fixedly connected to the top of the column 51. An installation hole is provided on the inner side of the top plate 52, and an electro-hydraulic rod 53 is fixedly connected to the inner side of the installation hole. A blade-fixing plate 54 is fixedly connected to the bottom of the electro-hydraulic rod 53, and a sliding hole is provided on the inner side of the blade-fixing plate 54. The blade-fixing plate 54 is slidably connected to the outer side of the column 51 through the sliding hole. The bottom of the column 51 is fixedly connected to the top of the worktable 1, and a cutting blade 55 is fixedly connected to the bottom of the blade-fixing plate 54. The cutting blade 55 is positioned between the two cleaning components 7. Through the above arrangement, stable support and precise movement of the cutting device are achieved. The column 51, as the main support component, ensures the stable installation and sliding function of the blade-fixing plate 54 through the connection of the top plate 52 and the electro-hydraulic rod 53. This design not only improves the movement accuracy of the cutting blade 55 but also enhances the stability and reliability of the entire device, providing a foundation for the precise cutting of optical composite films. As a further implementation of this solution, the unloading roller 2 includes a support, a motor, and a rotating roller. The bottom end of the support of the unloading roller 2 is fixedly connected to the worktable 1. The unloading roller 2 and the take-up roller 3 have the same structure. The arch frame 4 is U-shaped. One side of the arch frame 4 is fixedly connected to the electric telescopic rod 61. The number of arch frames 4 is the same as the number of take-up components 6. Through the above settings, the unloading and take-up functions of the optical composite film are realized. The combination of the support, motor, and rotating roller ensures the smooth transport of the optical composite film. As a further implementation of this solution, the bottom end of the scraper 79 is flush with the end of the receiving shell 62 away from the electric telescopic rod 61. A gap is provided between the bottom end of the scraper 79 and the receiving shell 62. An arc-shaped groove is provided at the upper end of the receiving shell 62. The arc-shaped groove of the receiving shell 62 fits against the outer side of the scraper 79. Through the above settings, the design of the scraper 79 and the receiving shell 62 realizes the automatic cleaning function of the adhesive on the outside of the blade. Through the fit between the arc-shaped groove of the receiving shell 62 and the outer side of the scraper 79, it can rotate by friction, thereby scraping off the adhesive on the outside of the blade and collecting it inside the receiving groove 63. This design not only reduces the accumulation of adhesive on the blade surface, but also improves the continuity and quality of cutting. As a further implementation of this solution, both ends of the scraper 79 extend into the shaft through hole 72. A bearing is fixedly connected to the inner side of the shaft through hole 72, and the inner side of the bearing in the shaft through hole 72 is fixedly connected to the outer side of the scraper 79. The outer side of the scraper 79 is in contact with one side of the cutting tool 55. The inner side of the pawl 77 has three cylindrical through holes. The through hole at the middle end of the pawl 77 is in contact with the outer side of the center post 75, one side of the pawl 77 is in contact with the lower end of the side block 73, and the lower end of the pawl 77 meshes with the outer side of the ratchet 78. Through the above settings, the rotation efficiency and stability are improved, and the function of mechanical transmission is realized. This design not only ensures the stable rotation of the pawl 77, but also drives the ratchet 78 to rotate through the helical teeth, further driving the unidirectional rotation of the scraper 79, ensuring the effectiveness of the scraper 79 in cleaning the cutting tool 55.

[0018] Workflow: When cutting the optical composite film, the optical composite film is sleeved on the outside of the feeding roller 2, and the other end is wound on the outside of the take-up roller 3. The motor of the take-up roller 3 is started to drive the rotating roller of the take-up roller 3 to rotate. The take-up roller 3 winds up the optical composite film, and the feeding roller 2 feeds the optical composite film. The optical composite film passes through the lower end of the arch frame 4. The electric hydraulic rod 53 is started to drive the fixed blade plate 54 to move downward. The fixed blade plate 54 slides on the outside of the column 51. The column 51 drives the cutting blade 55 to move downward at the same time. The cutting blade 55 cuts the optical composite film. During the cutting process, the optical composite film is adhered to the cutting blade 55 by the adhesive of the cut edge. When removing the adhesive from the outside of the cutting blade 55, the cutting blade 55 moves downwards according to the same principle. When the lower edge of the cutting blade 55 is at the lower end of the scraper 79, the electric telescopic rod 61 is activated to push the receiving shell 62 and the cleaning assembly 7 together towards the cutting blade 55. This prevents the scraper 79 from contacting the adhesive on the cutting blade 55. At this time, the blade body of the cutting blade 55 is in close contact with the outside of the scraper 79. The clamping of the two scrapers 79 also increases the stability of the cutting blade 55 during cutting. Under the action of friction between the cutting blade 55 and the outside of the scraper 79, the scraper 79 is forced to rotate. Under the pushing force of the electric telescopic rod 61, the friction between the scraper 79 and the cutting blade 55 is increased, causing the scraper 79 to move. When the scraper 79 rotates, it fits into the arc-shaped groove of the receiving shell 62. The arc-shaped groove of the receiving shell 62 then acts on the scraper 79. The outer side of the adhesive is scraped off, and the scraped adhesive is collected inside the receiving trough 63. At the same time, the scraper 79 drives the ratchet 78 to rotate. When the ratchet 78 rotates, it pushes the pawl 77 to rotate through the helical teeth. The side block 73 limits the pawl 77. The elastic torque of the spring 76 resets the pawl 77. This setting allows the scraper 79 to rotate only in one direction. After the optical composite film is cut, the cutting blade 55 moves upward when driven by the electric hydraulic rod 53. At this time, the scraper 79 and the cutting blade 55 are controlled according to the principle. When the cutting blade of the cutting blade 55 is aligned with the scraper 79, the scraper 79 and the cutting blade 55 are brought into contact by the electric telescopic rod 61. The scraper 79 scrapes off the outer side of the cutting blade 55. The scraped adhesive adheres to the outer side of the scraper 79, which makes it easier for the cutting blade 55 to cut the optical composite film again. Based on the above principles, the device can remove the adhesive generated after cutting by the cutting blade 55, and at the same time clean the scraper column 79 that scrapes off the adhesive, control the amount of adhesive on the outside of the cutting blade 55, improve the continuity of cutting the optical composite film, and thus improve the quality of cutting the optical composite film.
