Description

Technical Field

[0001] This invention belongs to the technical field of privacy film production and processing equipment, and particularly relates to a privacy film forming and cutting equipment. Background Technology

[0002] Privacy films are functional screen protectors widely used in electronic devices such as mobile phones, computers, tablets, and automotive displays. Through a special optical microstructure design, they effectively limit the screen's viewing angle, preventing others from peeping at the screen content and protecting user privacy. Currently, market demand is extremely high. In the industrial production of privacy films, forming and cutting are the core processing steps. Continuous rolls of privacy film must be precisely cut to set dimensions to obtain finished film sheets that meet specifications.

[0003] Currently, traditional privacy film forming and cutting equipment has significant shortcomings in actual production operations. Privacy films are mostly made of flexible polymers with an optical coating. During the cutting process, the high-speed cutting blade generates a large amount of fine privacy film debris, coating powder, and scrap particles. Most existing cutting equipment lacks a dedicated blade cleaning structure, making it easy for the debris to adhere to the blade edge and surface.

[0004] The aforementioned defects can cause multiple production problems: First, the adhering debris will be transferred to the surface of the finished privacy film with the reciprocating cutting action of the cutter, causing defects such as scratches, stains, and particle protrusions on the film surface, which will seriously reduce the surface smoothness, optical transparency and appearance quality of the privacy film, resulting in a decrease in product yield. Second, the long-term adhesion and accumulation of debris will wear down and dull the cutter blade, destroying the sharpness of the cutter. This will not only cause problems such as burrs, dimensional deviations and incomplete cutting of the film in subsequent cutting, which will greatly reduce the cutting accuracy and processing quality, but also shorten the service life of the cutter and increase the cost of equipment parts replacement and production operation and maintenance. Summary of the Invention

[0034] In one embodiment of the present invention, such as Figures 1-4 As shown, a privacy film forming and cutting equipment is provided, including a frame 1, an electrical control box 2, a feeding mechanism 3, a feeding mechanism 4, a cutting mechanism 5, and a unloading mechanism 6. The electrical control box 2 is fixed to the side of the frame 1 and is electrically connected to the feeding mechanism 3, the feeding mechanism 4, and the cutting mechanism 5 respectively. The feeding mechanism 3, the feeding mechanism 4, and the cutting mechanism 5 are arranged sequentially on the frame 1, and the unloading mechanism 6 is arranged on one side of the frame 1. The privacy film passes through the feeding mechanism 3 and the feeding mechanism 4 in sequence, and is cut by the cutting mechanism 5. The unloading mechanism 6 unloads the cut privacy film.

[0035] The cutting mechanism 5 includes a lifting component 51, a cutting component 52, and a cleaning component 53. The lifting component 51 is fixed to the frame 1, the cutting component 52 is fixed to the lifting component 51, the cutting component 52 moves up and down through the lifting component 51 and cuts the privacy film, and the cleaning component 53 is fixed to the cutting component 52.

[0036] The privacy film forming and cutting equipment provided in this application, through the cooperation of the upper activated carbon scraper 532 and the lower activated carbon scraper 533, can automatically and comprehensively clean the privacy film debris, coating powder and other impurities adhering to the blade surface and blade edge of the upper cutter 523 during the lifting operation of the upper cutter 523. This effectively solves the pain point of debris accumulation on the blades of traditional equipment, avoids debris transfer to the surface of the privacy film and causing product defects, significantly improves the surface quality and yield of the privacy film after cutting, and ensures the optical performance and appearance quality of the product. By cleaning the blade in real time, this invention avoids long-term accumulation of debris that wears down the blade edge, effectively protects the sharpness of the upper cutter 523, prevents the cutter from becoming dull, significantly extends the service life of the cutter, reduces the frequency of cutter replacement, and significantly reduces equipment maintenance costs and production consumable costs. At the same time, it avoids problems such as burrs, dimensional deviations and incomplete cutting caused by blade dulling, effectively improving cutting accuracy and processing consistency.

[0037] In another embodiment of the present invention, two lifting components 51 are provided and are arranged in parallel and spaced apart; the lifting component 51 includes a lifting cylinder 511, a lifting plate 512, a lifting slider, and a lifting slide rail 513. The lifting cylinder 511 is fixed to the frame 1 and electrically connected to the electrical control box 2. The lifting plate 512 is fixed to the lifting cylinder 511 and the lifting slider respectively. The lifting slider is slidably connected to the lifting slide rail 513.

[0038] In another embodiment of the present invention, the cutting component 52 includes a blade holder 521, an upper blade plate 522, and an upper cutting blade 523. Two blade holders 521 are provided and fixed to the lifting plate 512. The upper blade plate 522 is fixed to the bottom end of the two blade holders 521 respectively, and the upper cutting blade 523 is fixed to the bottom end of the upper blade plate 522.

[0039] In another embodiment of the present invention, the cleaning component 53 includes an upper cylinder 531, an upper activated carbon scraper 532, and a lower activated carbon scraper 533. Two upper cylinders 531 are provided and fixed to the frame 1. Both upper cylinders 531 are electrically connected to the electrical control box 2. The upper activated carbon scrapers 532 are respectively fixed to the two upper cylinders 531 and are positioned against the side of the upper cutter 523 near the feeding mechanism 6. The lower activated carbon scraper 533 is fixed to the top side of the frame 1 and positioned below the upper cutter 523. When the upper cutter 523 descends via the lifting component 51, its side contacts the lower activated carbon scraper 533. The contact surfaces of the upper and lower activated carbon scrapers 532 and 533 are made of high-density activated carbon material, which has good adsorption and dust removal effects and is soft in texture, preventing scratches on the blade edge. The upper activated carbon scraper 532, driven by the upper cylinder 531, adheres to the upper blade surface of the upper cutter 523, actively wiping the upper area of ​​the blade to remove residual dust and impurities, thus compensating for the blind spots of the lower scraper. The lower activated carbon scraper 533 is positioned below the upper cutter 523. During the lifting, cutting, and resetting process of the upper cutter 523, it slides along the blade edge and lower part of the blade, scraping and adsorbing privacy film debris and optical coating powder adhering to the blade edge and lower part of the blade. It focuses on cleaning the core cutting edge area, preventing debris accumulation that could lead to dulling and burrs. The upper and lower activated carbon scrapers 532 work together to achieve automatic cleaning of the entire blade surface of the upper cutter 523 without dead angles, eliminating debris accumulation and preventing contamination of the finished privacy film product, ensuring product quality, while also continuously protecting the blade's sharpness, improving cutting accuracy, and extending blade life. After each cutting operation, the upper cutter 523 descends to its lowest cutting position and then returns to its original position. During the return process, the outer wall of the upper cutter 523 slides in close contact with the lower activated carbon scraper 533. The lower activated carbon scraper 533 thoroughly scrapes away and adsorbs the debris and powder adhering to the blade and the lower part of the blade. Simultaneously, the electrical control box 2 controls the two upper cylinders 531 to extend synchronously, causing the upper activated carbon scraper 532 to slide against the upper blade surface of the upper cutter 523, cleaning any remaining impurities on the upper part of the blade. The upper and lower activated carbon scrapers 532 work together to clean both sides of the upper cutter 523, effectively preventing the accumulation of debris. The activated carbon scraper can effectively adsorb fine dust and debris, providing long-lasting cleaning, and is wear-resistant, durable, and easy to replace.

[0040] In another embodiment of the present invention, the feeding mechanism 3 includes an air-expansion shaft 31, a feeding roller 32, a feeding pressing roller 33, a feeding support roller 34, and a feeding plate 35. The air-expansion shaft 31 is rotatably connected to the bottom of the frame 1. The feeding roller 32 and the feeding pressing roller 33 are rotatably connected to the frame 1 in sequence, and are arranged in parallel and at intervals. The feeding support roller 34 is rotatably connected to the frame 1 and is disposed on one side of the feeding plate 35. The feeding plate 35 is fixed to the frame 1 and is provided with multiple feeding through holes. The air-expansion shaft 31 is rotatably mounted on the bottom of the frame 1 for mounting and fixing the privacy film roll. The roll is stably fixed by inflation, preventing the roll from shifting or loosening during the feeding process, and is compatible with roll sleeves of different inner diameters. Feeding roller 32 and feeding pressing roller 33 are connected in parallel rotation at the feed end of frame 1 from bottom to top, with intervals between them, forming a privacy film pressing and conveying channel. After the privacy film is discharged from the roll, it passes between feeding roller 32 and feeding pressing roller 33, and is tensioned and prevented from loosening by double roller pressing. Feeding support roller 34 is rotatably connected to the middle of frame 1 and is set on the side of feeding plate 35 to support and guide the privacy film and prevent it from sagging and wrinkling. Feeding plate 35 is horizontally fixed on frame 1, and multiple feeding through holes are evenly opened on the plate to allow for air ventilation and pressure relief, preventing the privacy film from being negatively attracted to the plate and ensuring stable conveying of the privacy film.

[0041] In another embodiment of the present invention, the feeding mechanism 4 includes a feeding motor, a driving pulley 42, a primary driven pulley 43, a primary feeding roller 44, a secondary driven pulley 45, a secondary feeding roller 46, a feeding belt 47, and a feeding pressing roller 48. The feeding motor is fixed to the frame 1 and fixedly connected to the driving pulley 42. The feeding motor is electrically connected to the electrical control box 2. The primary feeding roller 44 is fixedly connected to the primary driven pulley 43 and rotatably connected to the frame 1. The secondary feeding roller 46 is fixedly connected to the secondary driven pulley 45 and rotatably connected to the frame 1. The feeding belt 47 is sequentially wound around the driving pulley 42, the primary driven pulley 43, and the secondary driven pulley 45. The feeding pressing roller 48 is rotatably connected to the frame 1 and is disposed above the secondary feeding roller 46.

[0042] When the feeding mechanism 4 is working, the feeding motor drives the active pulley 42 to rotate, which in turn drives the two sets of driven pulleys and corresponding feeding rollers to rotate synchronously through the feeding belt 47, so as to achieve uniform speed conveying of the anti-peeping film. The dual-stage feeding structure can greatly improve the feeding stability and effectively avoid problems such as slippage, deviation and uneven length during conveying.

[0043] In another embodiment of the present invention, the feeding mechanism 6 includes a feeding frame 61 and a feeding plate 62. The feeding frame 61 is disposed on one side of the frame 1, and the feeding plate 62 is fixed to the feeding frame 61 at an incline and disposed on one side of the cutting assembly 52. ​​The feeding plate 62 is provided with multiple feeding through holes. The feeding mechanism 6 is used for automatically collecting and feeding the finished privacy film after cutting. The feeding plate 62 is fixed at an incline at the top of the feeding frame 61, with the incline angle set to 15°-30°. The high position is connected to the cutting station, and the low position faces the collection area, so that the finished film can slide smoothly by its own weight and avoid jamming. The feeding plate 62 has multiple feeding through holes evenly distributed on its body, which can effectively break the negative pressure adsorption and prevent the thin privacy film from sticking to the surface of the feeding plate 62, ensuring continuous and smooth feeding.

[0044] The privacy film forming and cutting equipment provided in this application operates as follows: After the equipment is started, the electrical control box 2 coordinates the operation of each mechanism. The air shaft 31 drives the privacy film roll to be automatically fed. The privacy film is pressed and tightened by the feeding roller 32 and the feeding pressing roller 33, and then guided by the feeding plate 35 and the feeding support roller 34 into the feeding mechanism 4. The feeding motor drives the double-stage feeding roller to uniformly convey the privacy film and accurately push the privacy film to the cutting station. Then, the lifting component 51 drives the cutting component 52 to descend, and the upper cutter 523 completes the fixed-length cutting of the privacy film. After the cutting is completed, the cutting component 52 rises and resets. During the reset process, the upper activated carbon scraper 532 and the lower activated carbon scraper 533 of the cleaning component 53 simultaneously complete the chip removal and cleaning of the entire surface of the blade. The cut finished film falls into the inclined unloading plate 62 and automatically slides down to complete the unloading. This cycle is repeated to realize continuous automated forming and cutting operations.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
