TECHNICAL FIELD

[0001] The present application relates to the technical field of glue coating, in particular to a color-changing film surface glue coating device and a using method thereof. BACKGROUND

[0002] With the increasing demand for personalized modification of automobiles, the market demand for color-changing films, which can quickly change the appearance of automobiles and have the function of protecting the original paint, continues to rise. In the production process of color-changing films, surface gluing is one of the key processes, and the uniformity of the glue layer directly determines the sticking performance, service life and appearance texture of the color-changing film. In order to realize the automatic and continuous coating of glue, various color-changing film surface gluing devices have been developed in the related technical field.

[0003] In the actual operation process of the existing color-changing film surface gluing device, there are still many technical defects, which are specifically manifested in the following two core problems: first, the color-changing film is usually continuously conveyed in the form of a roll, and the conveying mechanism of the existing device adopts a simple roller traction method, which only relies on the friction force between the roller and the color-changing film to realize conveying. In the process of high-speed conveying, the color-changing film is easily affected by factors such as deviation of roller parallelism, fluctuation of traction tension, and uneven thickness of the film edge, resulting in transverse deviation. The deviation of the color-changing film will cause the relative position of the subsequent coating mechanism to deviate, thereby causing the edge part of the color-changing film product to not meet the sticking requirements, reducing the product qualification rate; second, the color-changing film substrate is prone to adhere to dust, fibers and other impurities in the environment during storage, transportation or early processing. When the color-changing film substrate with impurities enters the gluing process, the impurities will combine with the glue to form protrusions. The dust suction pipe of the existing dust suction mechanism is usually fixedly connected or connected in a complex bolted manner. When the inner wall of the dust suction pipe is blocked due to long-term adsorption of dust and fibers, it needs to be disassembled and cleaned or replaced.

The output end of the electric push rod 14 is fixedly connected to the moving plate 11. An adjusting slide rail 25 is fixedly connected to the end of the moving plate 11 away from the mounting plate 5. A sliding slide rail 25 is slidably connected in the adjusting slide rail 25.

A slider 23 is slidably connected inside the support slide rail 9. An arc-shaped plate 24 is fixedly connected to the end of the slider 23 away from the support slide rail 9. The outer walls of multiple arc-shaped plates 24 abut against the membrane roll 10. A bidirectional screw 26 is rotatably connected inside the adjusting slide rail 25. The two sliding blocks 27 are threadedly connected to the bidirectional screw 26, and the two sliding blocks 27 are symmetrically distributed. An ion air bar 28 is fixedly connected to the end of the sliding block 27 away from the moving plate 11. A lifting groove 48 is provided on the moving plate 11. A lifting block 49 is slidably connected inside the lifting groove 48. The lifting block 49 is located away from the mounting plate 5. The worktable 2 is rotatably connected to a guide roller 7. The upper surface of the worktable 2 is fixedly connected to an air flotation plate 12, a protective cover 3, and a fixing frame 4. The protective cover 3 is located above the air flotation plate 12. The fixing frame 4 is slidably connected to a first template 15. The end of the first template 15 away from the rotating disk 6 is connected to a second template 44, and the first template 15 and the second template 44 are threaded together. The first template 15 has a storage cavity 46. The end of the first template 15 near the rotating disk 6 has a glue inlet hole 16, and the glue inlet hole 16 is connected to the storage cavity 46. The second template 44 has an air extraction groove 45 and a glue discharge groove 47, and both the air extraction groove 45 and the glue discharge groove 47 are connected to the storage cavity 46.

[0021] Specifically, firstly, the film roll 10 is placed on the arc plate 24. The drive motor of the rotating plate 20 drives the rotating plate 20 to rotate. The rotation of the rotating plate 20 drives the arc groove 22 to rotate. Under the drive of the arc groove 22, the adjusting rod 21 moves along the telescopic groove 17, which in turn drives the telescopic block 18 to move along the telescopic groove 17 to adjust the position of the support slide rail 9. A locking block is preset in the arc groove 22. After the adjusting rod 21 is adjusted, the locking block limits the adjusting rod 21. The film roll 10 is supported by multiple arc plates 24 to prevent the film roll 10 from shaking during rotation. The guide roller 7 moves along the lifting groove 48 under the force of the color-changing film and is linked with the pressure sensor preset in the lifting groove 48 to monitor the force of the color-changing film in real time and automatically adjust the conveying speed of the color-changing film.

[0022] Secondly, the motor-driven slide block 27, matched with the bidirectional screw 26, moves along the adjusting slide rail 25 to adjust the distance between the ion fan bar 28 and the dust collection box 29 and the color-changing film. The ion fan bar 28 eliminates static electricity on the color-changing film, and the dust collection box 29 cleans the dust on the adhesive surface of the color-changing film. According to the width of the color-changing film, the drive motor 40 drives the pull plate 39 to rotate and adjust the position of the slide 43. The end of the slide 43 away from the fixed plate 8 is preset with a correction sensor. The sensor detects the conveying position of the color-changing film in real time. When the color-changing film deviates, the telescopic rod matched with the slider 23 in the support slide rail 9 pushes the arc plate 24 to adjust the position of the film roll 10. The electric push rod 14 pushes the moving plate 11 to synchronously adjust the position of its components. The telescopic rod matched with the first template 15 adjusts the distance between the glue discharge groove 47 and the color-changing film to avoid direct contact between them. The glue bucket matched with the first template 15 is equipped with a stirring rack to dissolve the glue. During stirring, the vacuum pump in the glue tank draws a vacuum into the glue, expelling air bubbles. The glue, after the air bubbles are expelled, is fed into the storage chamber 46 through the glue inlet 16 via a pre-set glue tube. The first template 15 and the second template 44 are connected as a whole by bolts. The second template 44 has a vacuum groove 45, which is connected to the storage chamber 46, to perform a second vacuum on the glue fed into it. The air inlet of the vacuum groove 45 is equipped with a miniature check valve to prevent glue backflow. For high-viscosity glue, the vacuum level can be appropriately increased to -0.04MPa to -0.05MPa, while for low-viscosity glue, it should be reduced to -0.02MPa to -0.03MPa. It is forbidden to exceed -0.05MPa. Under the action of the storage chamber 46, the glue flows more evenly. The glue flow components are all equipped with heating components to maintain the fluidity of the glue. The glue flows evenly to the surface of the color-changing film below through the glue outlet 47, completing the coating of the color-changing film surface with glue.

[0023] refer to Figures 1-7The auxiliary components include a movable plate 11 and a dust collection box 29. A dust collection pipe 30 is fixedly connected to one end of the dust collection box 29 near the rotating disk 6. A sleeve 31 is inserted into the outer wall of the dust collection pipe 30. A slot 36 is provided on the dust collection pipe 30. A limiting groove 34 is provided on the sleeve 31. A push ring 33 is slidably connected in the limiting groove 34 and is slidably connected to the sleeve 31. A plurality of rolling grooves 38 are evenly provided on the sleeve 31. A ball bearing 37 is slidably connected in the rolling groove 38 and is engaged with the slot 36. One of the slides 27 is fixedly connected to the dust collection box 29. A dust outlet hose 13 is fixedly connected to one end of the sleeve 31 away from the dust collection box 29. An ionizer 28 is fixedly connected to one end of the slide 27 away from the movable plate 11. A compression spring 35 is sleeved on the outer wall of the sleeve 31. A fixing ring 32 is fixedly connected to the outer wall of the sleeve 31. The compression spring 35 is located between the push ring 33 and the fixing ring 32.

[0024] Specifically, pull the push ring 33 away from the dust collection box 29 along the limiting groove 34. As the push ring 33 moves away from the rolling groove 38, the pressure of the push ring 33 on the ball 37 is released. At this time, the compression spring 35 is in a compressed state. Remove the sleeve 31 from the suction pipe 30 to complete the disassembly of the sleeve 31 and the dust outlet hose 13. Pull the push ring 33 away from the dust collection box 29 along the limiting groove 34 again to insert the suction pipe 30 into the sleeve 31. When the suction pipe 30 abuts against the step pre-cut in the sleeve 31, the locking groove 36 moves below the rolling groove 38. Release the push ring 33. Under the rebound force of the compression spring 35, push the push ring 33 to slide along the limiting groove 34, press the ball 37 into the rolling groove 38, and limit the ball 37 so that the ball 37 is engaged with the locking groove 36, completing the installation of the sleeve 31.

[0025] The method of using the color-changing film surface adhesive coating device includes the following steps: S1. Place the membrane roll 10 on the arc plate 24. The drive motor of the rotating plate 20 rotates and drives the rotating plate 20 to rotate. The arc groove 22 opened on the rotating plate 20 pushes the adjusting rod 21 and the telescopic block 18 to move along the telescopic groove 17, so that the arc plate 24 abuts against the inner wall of the membrane roll 10 to prevent it from shifting during rotation. S2. During the conveying of the color-changing film, the guide roller 7 and the lifting block 49 move along the lifting groove 48 under the action of the color-changing film. They are linked with the pressure sensor preset in the lifting groove 48 to monitor the force on the color-changing film in real time and automatically adjust the conveying speed of the color-changing film. The correction sensor pre-installed on the carriage 43 monitors whether the conveying of the color-changing film is deviated in real time. Two ion air bars 28 symmetrically arranged on both sides of the color-changing film eliminate static electricity on the color-changing film. The dust collection box 29 adsorbs the dust on the surface of the color-changing film that needs to be coated. When it is necessary to clean the dust outlet hose 13, the push ring 33 is pulled away from the dust collection box 29 along the limiting groove 34 to release the limit of the push ring 33 on the ball 37 and complete the disassembly of the dust outlet hose 13. S3. The first template 15 and the second template 44 are connected by bolts. The mixing rack in the glue bucket of the first template 15 agitates the glue. The vacuum pump in the glue bucket evacuates the glue to eliminate air bubbles. The glue after eliminating air bubbles is fed into the storage cavity 46 through the glue inlet hole 16. The air extraction groove 45 on the second template 44 evacuates the glue in the storage cavity 46 again to prevent air bubbles from forming during the process of the glue entering the storage cavity 46 and to improve the uniformity of glue flow. The glue is coated on the color-changing film below through the glue discharge groove 47.

[0026] The working principle of this invention is as follows: The film roll 10 is placed on the arc plate 24. The drive motor of the rotating plate 20 rotates, causing the rotating plate 20 to rotate. The arc groove 22 on the rotating plate 20 pushes the adjusting rod 21 and the telescopic block 18 to move along the telescopic groove 17, so that the arc plate 24 abuts against the inner wall of the film roll 10, preventing it from shifting during rotation. During the color-changing film conveying process, the guide roller 7 and the lifting block 49 move along the lifting groove 48 under the action of the color-changing film. They are linked with the pressure sensor preset in the lifting groove 48 to monitor the force on the color-changing film in real time and automatically adjust the conveying speed of the color-changing film. The correction sensor pre-installed on the carriage 43 monitors in real time whether the color-changing film is shifted during conveying. Two ion air bars 28 symmetrically arranged on both sides of the color-changing film eliminate static electricity on the color-changing film. The dust collection box 2... 9. Dust on the surface to be coated with the color-changing film is adsorbed. When the dust outlet hose 13 needs to be cleaned, the push ring 33 is pulled away from the dust collection box 29 along the limiting groove 34 to release the limiting of the push ring 33 on the ball 37, thus completing the disassembly of the dust outlet hose 13. The first template 15 and the second template 44 are connected by bolts. The stirring rack in the glue bucket of the first template 15 stirs the glue. The vacuum pump of the glue bucket evacuates the glue to eliminate air bubbles. The glue after eliminating air bubbles is fed into the storage cavity 46 through the glue inlet hole 16. The air extraction groove 45 on the second template 44 evacuates the glue in the storage cavity 46 again to prevent air bubbles from appearing during the process of the glue entering the storage cavity 46 and to improve the uniformity of glue flow. The glue is coated on the color-changing film below through the glue discharge groove 47.

9. The color-changing film surface adhesive coating device according to claim 8, characterized in that: The first template (15) is slidably connected inside the fixed frame (4). The end of the first template (15) away from the rotating disk (6) is connected to the second template (44), and the first template (15) and the second template (44) are threadedly connected. The first template (15) has a storage cavity (46) inside. The end of the first template (15) near the rotating disk (6) has a glue inlet hole (16), and the glue inlet hole (16) is connected to the storage cavity (46). The second template (44) has a suction groove (45) and a glue discharge groove (47), and the suction groove (45) and the glue discharge groove (47) are both connected to the storage cavity (46).

10. A method for using a color-changing film surface adhesive coating device, characterized in that, Includes the following steps: S1. Place the membrane roll (10) on the arc plate (24). The drive motor of the rotating plate (20) rotates and drives the rotating plate (20) to rotate. The arc groove (22) opened on the rotating plate (20) pushes the adjusting rod (21) and the telescopic block (18) to move along the telescopic groove (17), so that the arc plate (24) abuts against the inner wall of the membrane roll (10) to prevent it from shifting during rotation. S2. During the conveying process of the color-changing film, the guide roller (7) and the lifting block (49) move along the lifting groove (48) under the action of the color-changing film. They are linked with the pressure sensor preset in the lifting groove (48) to monitor the force of the color-changing film in real time and automatically adjust the conveying speed of the color-changing film. The correction sensor pre-installed on the slide (43) monitors whether the conveying of the color-changing film is deviated in real time. Two ion wind bars (28) symmetrically arranged on both sides of the color-changing film eliminate static electricity on the color-changing film. The dust collection box (29) adsorbs the dust on the surface of the color-changing film that needs to be coated. When it is necessary to clean the dust outlet hose (13), the push ring (33) is pulled away from the dust collection box (29) along the limiting groove (34) to release the limit of the push ring (33) on the ball (37) and complete the disassembly of the dust outlet hose (13). S3. The first template (15) and the second template (44) are connected by bolts. The stirring rack in the glue bucket of the first template (15) stirs the glue. The vacuum pump of the glue bucket evacuates the glue to eliminate air bubbles. The glue after eliminating air bubbles is fed into the storage cavity (46) through the glue inlet hole (16). The air extraction groove (45) on the second template (44) evacuates the glue in the storage cavity (46) again to prevent air bubbles from appearing in the process of the glue entering the storage cavity (46) and to improve the uniformity of glue flow. The glue is coated on the color-changing film below through the glue discharge groove (47).
