Description

Technical Field

[0001] The utility model relates to the technical field of automobile film pasting, in particular to a high-precision cutting tool for automobile film pasting. Background Technique

[0002] Different vehicle models and vehicle windows have different shapes and sizes. In order to ensure that the film can fit tightly on the vehicle window without gaps or bubbles, it is necessary to cut according to the actual shape and size of the vehicle window, which can ensure good sealing between the film and the vehicle window, and improve the stability and aesthetics of the film pasting.

[0003] After pasting the film on the surface of the automobile, it is necessary to cut and trim the gaps of the automobile. Due to the limited space at the gaps, the cutting scissors are very likely to touch the side edges inside the gaps during operation, resulting in scratches on the vehicle. After cutting, the two sides of the film that are cut open are prone to warping due to the loss of the original tension or adhesion, resulting in the film being unable to fit tightly inside the gaps. Warping not only affects the overall aesthetics, but also causes the film to gradually fall off or be damaged under the influence of wind, sun and rain;

[0004] Since the gaps are small and fingers cannot directly reach in for pressing, usually tools (such as small rollers, scrapers, etc.) need to be used to reach into the gaps to finely press the warped film. This process is not only time-consuming and laborious, but also may further damage the film or vehicle paint due to improper use of the tools. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 7 , the present invention provides a technical solution:

[0028] Refer to Figures 1 - 6 As shown in , a high-precision cutting tool for automotive film includes a blade body 1, and a blade 2 is fixedly installed on the outer wall of the blade body 1. It includes two airbags 3, which are arranged on both sides of the blade 2, and the outer wall of the airbag 3 is fixedly connected to the outer wall of the blade 2. A connecting pipe 4 has one end communicating with the two airbags 3 respectively and the other end extending to the outside for communicating with an external air supply unit.

[0029] When holding the blade body 1 and driving the blade 2 to slide towards the vehicle film at the vehicle gap, since the cut part is at the gap, the blade 2 will penetrate into the gap. At this time, the two airbags 3 will support on both sides of the gap, and air can be inflated into the connecting pipe 4. Then the air supply unit transports gas to the connecting pipe 4, and then through the connecting pipe 4 to the airbag 3 to make the airbag 3 expand. The intake air volume entering the airbag 3 can be controlled according to the width of the gap to make the airbag 3 reach an appropriate degree of expansion. The two airbags 3 support on both sides of the blade 2, which can play a limiting role on the blade 2, so that the blade 2 will not easily slide to the side of the gap and cause scratches to the vehicle. When the blade 2 cuts the vehicle film at the gap, the inflated airbag 3 will push the curled vehicle film to the side of the gap, so that the curled vehicle film fits the inner wall of the gap again.

[0030] Refer to Figures 1 - 7, one end of the connecting pipe 4 away from the airbag 3 extends into the interior of the blade body 1. The air supply unit includes a piston 10 slidably connected to the inner wall of the blade body 1. An outer wall of the piston 10 is fixedly installed with a slider 11. A top of the slider 11 is fixedly installed with a fixing rod 12. Both the fixing rod 12 and the slider 11 are located outside the blade body 1.

[0031] Sufficient gas is reserved in the blade body 1. Pull the fixing rod 12 to drive the slider 11 and the piston 10 to slide along the inside of the blade body 1. When the piston 10 slides to one end away from the blade 2, the gas in the airbag 3 will be pumped into the blade body 1 through the connecting pipe 4, and then the airbag 3 will contract. When the piston 10 is moved to slide in the direction of the blade 2, the gas will be pushed into the connecting pipe 4 and the airbag 3, causing the airbag 3 to expand.

[0032] Refer to Figure 3 , a square groove 13 is formed on one side of the blade body 1. The slider 11 is located inside the square groove 13 and is slidably connected to the square groove 13.

[0033] The square groove 13 provides a space for the slider 11 to move, facilitating the sliding of the slider 11.

[0034] Refer to Figure 1 and Figure 5 , a guide plate 5 is fixedly installed on an outer wall of the blade body 1. The guide plate 5 is provided with two sliding grooves 6. The guide plate 5 is provided with a chamber 19. An inner wall of the chamber 19 is slidably connected to a belt 14. The slider 11 is located inside the guide plate 5. The fixing rod 12 is inserted into the belt 14. The fixing rod 12 is located between the two sliding grooves 6.

[0035] The guide plate 5 is fixed on one side of the blade body 1 and blocks the square groove 13, forming a sealed environment inside the blade body 1 to prevent gas leakage. The sliding groove 6 provides a space for the fixing rod 12 to slide. The belt 14 blocks the sliding groove 6 to prevent gas from leaking through the sliding groove 6. Then when the fixing rod 12 moves, it will drive the belt 14 to slide along the chamber 19, not only playing a sealing role but also not affecting the movement of the fixing rod 12.

[0036] Refer to Figure 7 , the blade body 1 is provided with two through holes 16. Inner walls of the through holes 16 are fixedly installed with sealing rings 17. The connecting pipe 4 is inserted into the sealing rings 17 and an outer wall of the connecting pipe 4 is fixedly connected to an inner wall of the sealing rings 17.

[0037] The through holes 16 provide a space for the connecting pipe 4 to be inserted into the blade body 1. The sealing rings 17 seal the gap between the through holes 16 and the connecting pipe 4 to prevent gas leakage.

[0038] Refer to Figure 7 , a gas collecting hood 18 is fixedly installed on an inner wall of the blade body 1. Ends of the connecting pipe 4 located inside the blade body 1 are all located inside the gas collecting hood 18.

[0039] The gas collecting hood 18 enlarges the gas inlet area of ​​one end of the connecting tube 4 , so that the gas in the blade body 1 can more easily directly pass through the gas collecting hood 18 and enter the connecting tube 4 .

[0040] See also Figures 1 - 5 A gripping rod 7 is fixedly mounted on the top of the fixing rod 12 , and the gripping rod 7 extends to the outside of the guide plate 5 , and a plug hole 15 is provided on the belt 14 .

[0041] The grip rod 7 increases the length and contact area of ​​the fixing rod 12, making it convenient for the user to move the grip rod 7 with his fingers to drive the piston 10 to move. The socket 15 provides space for the fixing rod 12 to extend to the outside of the guide plate 5, and the inner wall of the socket 15 is in close contact with the outer wall of the fixing rod 12, so there is no need to worry about air leakage.

[0042] See also Figures 1 - 2 A handle 8 is fixedly mounted on the outer wall of the blade body 1 , and an anti-slip sleeve 9 is fixedly mounted on the outer wall of the handle 8 .

[0043] The user holds the handle 8 and then presses the top of the blade 1 with the index finger, which makes it easy to apply pressure to the blade 2, making the blade 2 more stable when moving. The anti-slip sleeve 9 increases friction to prevent the user's hand from slipping and causing the blade 1 to fall off the hand.

[0044] Working principle:

[0045] When the blade 1 is held and the blade 2 is driven to slide toward the film at the gap of the car, since the cut part is at the gap, the blade 2 will go deeper into the gap. At this time, the two airbags 3 will be supported on both sides of the gap, and air can be inflated into the connecting pipe 4, and then the air supply unit transports the gas to the connecting pipe 4, and then transports the gas to the airbag 3 through the connecting pipe 4 to expand the airbag 3. The amount of air entering the airbag 3 can be controlled according to the width of the gap, so that the airbag 3 can reach a suitable expansion degree. The two airbags 3 are supported on both sides of the blade 2, which can limit the blade 2, so that the blade 2 will not easily slide to the side of the gap and cause scratches to the car. When the blade 2 cuts the film at the gap, the inflated airbag 3 will push the warped film to the side of the gap, so that the warped film fits the inner wall of the gap again.

[0046] The guide plate 5 is fixed to one side of the blade body 1 and blocks the square groove 13, so that a sealed environment is formed in the blade body 1 to prevent gas leakage. The slide groove 6 provides a sliding space for the fixed rod 12, and the belt 14 blocks the slide groove 6 to prevent gas leakage from the slide groove 6. Then, when the fixed rod 12 moves, it will drive the belt 14 to slide along the chamber 19, which not only plays a sealing role, but also will not affect the movement of the fixed rod 12.
