Technical Field

[0001] The utility model specifically relates to a device for automatically trimming the edge of a glass protective film. Background Technique

[0002] A glass protective film is a film attached to the surface of glass. The main types include PE protective film, AS protective film, and tempered glass protective film. The glass protective film can not only prevent injuries caused by the breakage of glass due to external impact, but also prevent the residue of fingerprints, oil stains, and other stains on the glass. Its main functions include heat insulation, heat preservation, ultraviolet ray blocking, anti-glare, decoration, privacy protection, safety explosion-proof, etc. With the progress of technology and the increasing demand in people's daily life, as an important protective material, the glass protective film is widely used in homes, offices, restaurants, shopping mall fronts, and personal private spaces, etc.

[0003] To complete the film pasting process for a piece of glass, first, it is necessary to clean and prepare the glass surface to remove dust and oil on the glass surface to ensure that the protective film can be firmly adhered. Then, operations such as cutting the protective film, pasting the protective film, exhausting air bubbles, and cutting off the excess edges are continued.

[0004] However, during the process of pasting the glass protective film, the edge treatment of the glass protective film is an important process. The traditional edge treatment method of the glass protective film generally adopts manual cutting or manual edge trimming. The main method is to manually remove its excess edges with a utility knife. This not only has low efficiency, is prone to unevenness or defects, seriously affecting the overall appearance and use effect of the protective film, but also has certain potential safety hazards. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a design device that can automatically remove the edges of the glass protective film to solve the technical problems of low efficiency in edge treatment of the glass protective film and being prone to unevenness or defects.

[0031] A device for automatically trimming the edges of a glass protective film, as Figure 1 - Figure 5 shown, includes a table 1 and a main body board 10. Fixed plates 2 are arranged on both sides of the top of the table 1. A motor 13 is arranged on one side of the fixed plate 2. A support table 4 is fixed on the top of the fixed plate 2. A positive and negative threaded rod 23 is movably installed on one side of the support table 4. A support cross beam 11 is fixed between the two support tables 4. The outer wall of the positive and negative threaded rod 23 is sleeved with the main body board 10. A connecting column 24 is fixed at the bottom of the main body board 10. A blade 20 is fixed at the bottom of the connecting column 24. A conveying component is installed on the top of the table 1. A pressing component is installed at the bottom of the connecting column 24, which is convenient for adjusting the distance between the blades 20. By setting the positive and negative threaded rod 23, the distance between the two main body boards 10 can be adjusted during rotation, so as to trim the edges of glass protective films of different sizes and models, improving the work efficiency.

[0032] Please refer to Figure 1 - Figure 3 , the conveying component includes two conveyor wheels 16 installed inside the fixed plate 2. A fixed rod 12 is fixed at the end of the conveyor wheel 16, and the end of the fixed rod 12 is connected to the output end of the motor 13. A fixed frame 14 is fixed at the bottom of the motor 13. The outer walls of the two conveyor wheels 16 are sleeved with a conveyor belt 8. A motor 13 is arranged at the end of one of the conveyor wheels 16. By setting the conveying component, it is convenient to feed materials, replacing the traditional manual feeding method and improving the work efficiency.

[0033] Please refer to Figure 1 , Figure 2 , Figure 3, a connecting plate 21 is fixed to one side of the main body plate 10, and a partition plate 9 is fixed to the end of the connecting plate 21. One side of the partition plate 9 is provided with an inclined surface. By arranging the connecting plate 21, the partition plate 9 can be driven to move when the main body plate 10 moves. The arrangement of the partition plate 9 can separate the waste generated when the blade 20 trims the edge of the protective film, so that the waste will not contact the glass.

[0034] Please refer to Figure 1 - Figure 3 , a plurality of groups of rollers 5 are arranged inside the fixing plate 2, and the diameter of the rollers 5 is smaller than that of the conveyor wheels 16. The top of the rollers 5 is in contact with the top end of the inner wall of the conveyor belt 8. The diameter of the rollers 5 is smaller than that of the conveyor wheels 16. By arranging the rollers 5, the conveyor belt 8 can be supported, preventing the conveyor belt 8 from sagging when the glass is placed above it, and at the same time reducing the friction with the conveyor belt 8.

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 , a sliding groove 22 is formed inside the support cross beam 11, and an inclined surface groove 15 is formed on one side of the inner wall of the sliding groove 22. The connecting plate 21 connects the main body plate 10 and the partition plate 9 through the inclined surface groove 15. By arranging the groove 22, the moving direction of the main body plate 10 can be limited, so that the main body plate 10 can only slide directionally inside it, realizing the simultaneous movement of the main body plate 10 and the partition plate 9.

[0036] Please refer to Figure 4 - Figure 5 , the pressing assembly includes an inner rod 25 fixed to the bottom of the connecting column 24, an outer rod 26 is sleeved on the outer wall of the inner rod 25, a spring 28 is fixed inside the outer rod 26, and a pressing wheel 27 is movably installed at the bottom of the inner rod 25, and the pressing wheel 27 is located on one side of the blade 20.

By the spring 28 giving a pressure to the pressing wheel 27, the pressing wheel 27 can press the protective film tightly, avoiding the situation of warping during edge trimming. The pressing wheel 27 can reduce the friction with the protective film and avoid damaging the protective film.

[0037] Please refer to Figure 1 、 Figure 3 、 Figure 4 , an isolation plate 7 is installed on one side of the top of the table 1, and the isolation plate 7 is attached to the outer wall of the conveyor belt 8. A collection box 6 is installed on one side of the table 1 to collect the cut surplus edges. At the same time, the surplus edges may adhere to the conveyor belt 8 during the conveying process of the conveyor belt 8. The isolation plate 7 removes the surplus edges adhering to the conveyor belt 8 and then slides into the collection box 6 for easy collection and cleaning.

[0038] The working principle of the present utility model is as follows: Before the process of removing the edges of the glass protective film, the equipment is first debugged. According to the remaining distance of the glass protective film, the distance between the two groups of blades 20 is adjusted. Manually shake the rocker 17, so that the positive and negative threaded rod 23 rotates. According to the screw principle, when the positive and negative threaded rod 23 rotates, the two groups of main body plates 10 will slide on the outer wall of the positive and negative threaded rod 23 and perform relative movement, and the two groups of blades 20 approach or move away from each other.

[0039] Turn on the motor 13. The motor 13 rotates the conveyor pulley 16 through the fixed rod 12, drives the conveyor pulley 16 at the tail end through the conveyor belt 8, and places the glass to be edge-removed above the conveyor belt 8. The glass slowly displaces to directly below the main body plate 10 during the operation of the conveyor belt 8. Before the edge-removing operation of the glass protective film, the glass will first contact the roller 18. The roller 18 is provided to prevent the corners of the glass from directly colliding with the cutting edges of the blades 20, and at the same time, it also has the function of finely adjusting the position of the glass. The glass will not contact the support column 19. When the glass contacts the roller 18, the roller 18 will rotate to reduce the friction of the glass. After the glass passes through the roller 18, the glass will contact the extrusion assembly, and the pressing wheel 27 rolls and presses the protective film on the glass to avoid the situation of the glass protective film warping when cutting the protective film. Then, the blades 20 will cut the remaining edges of the glass protective film. Through the transmission of the conveyor belt 8, the excess protective film contacts the partition plate 9. Since the partition plate 9 has a certain angular surface that becomes wider from narrow, the excess protective film will separate from the glass. The glass is transmitted to the tail end of the machine through the conveyor belt 8, while the excess protective film is concentrated on both sides of the edge of the conveyor belt 8 by the connecting plate 21 and is transmitted to the tail end through the conveyor belt 8. An isolation plate 7 is installed at the tail end of the conveyor belt 8, and the isolation plate 7 separates the protective film on the belt from the conveyor belt 8. The collection box 6 at the tail end of the mechanical device collects the cut waste materials.
