Description

Technical Field

[0001] This utility model relates to the field of automotive protective film production technology, specifically to a dust removal and cleaning mechanism for automotive protective film production. Background Technology

[0002] In the production process of automotive protective films, from substrate forming and coating processing to finished product winding, each stage is susceptible to contamination from environmental impurities such as dust, fibers, and tiny particles. If these impurities remain on the surface or within the layers of the protective film, they can cause bubbles and wrinkles when applied to the car body, affecting its appearance. They can also reduce the adhesion between the protective film and the car's paint, shorten its lifespan, and may even scratch the paint during later use. Therefore, dust removal and cleaning have become an indispensable core process in automotive protective film production. Developing efficient, stable, and sustainable dust removal and cleaning systems is crucial for improving the production quality of automotive protective films and enhancing their market competitiveness.

[0003] Chinese utility model patent CN223011368U discloses a dust removal device for protective film production. It includes telescopic platforms located on both sides of the upper surface of a workbench, symmetrically arranged on the upper surface. A top working plate is fixedly connected to the upper surface of the telescopic platforms, and an adhesion roller is provided at the bottom of the top working plate. This utility model, by setting up telescopic platforms and driving a motor to move telescopic rods up and down within the telescopic platforms, can accommodate protective films of different thicknesses during dust removal. The adhesion rollers, with their adhesion shafts, can sequentially adhere dust remaining on the surface of the protective film during operation.

[0004] However, the adhesion roller of the dust removal device for the production of protective film of this utility model adheres to the dust on the surface of the protective film by rotating the adhesion shaft. However, this adhesion method mainly relies on the adhesive material on the surface of the adhesion roller. Over time and with repeated use, the adhesive material on the surface of the adhesion roller will gradually lose its adhesiveness, resulting in a decrease in adhesion effect and inability to effectively remove impurities from the surface of the protective film, thereby affecting the production quality of automotive protective film. Therefore, a dust removal and cleaning mechanism for the production of automotive protective film is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust removal and cleaning mechanism for automotive protective film production, which has advantages such as high-efficiency dust removal and solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dust removal and cleaning mechanism for automotive protective film production includes a machine body, a winding box fixedly connected to one side of the machine body, and a winding device disposed on one side of the winding box. A dust suction mechanism is disposed on the top of the machine body, a cleaning mechanism for adsorbing impurities on both sides of the protective film is disposed on the outside of the machine body, and a lifting mechanism for adjusting the lifting of the cleaning mechanism is disposed on the top of the machine body.

[0008] The cleaning mechanism includes a connecting plate and a collection box disposed on the outside of the machine body.

A conveying pipe is fixedly connected between the collection box and the suction pipe.

[0009] The lifting mechanism includes an electric telescopic cylinder fixedly installed on the top of the machine body and a movable plate fixedly connected to the output end of the electric telescopic cylinder.

The connecting plate is fixedly connected to the bottom of the mounting plate.

[0010] Furthermore, there are four sets of connecting plates and two sets of straws, with the two sets of straws arranged in a rectangular shape inside the four sets of connecting plates.

[0011] Furthermore, the two sets of connecting plates at the bottom are fixedly connected to the outside of the machine body, and the two sets of connecting plates at the top are fixedly connected to the bottom of the mounting plate.

[0012] Furthermore, a corrugated pipe is fixedly connected between the two sets of straws, a baffle is slidably connected inside the collection box, and a movable opening adapted to the baffle is opened inside the collection box.

[0013] Furthermore, the top straw is slidably connected to the outside of the machine body via a movable plate and is located on the upper surface of the bottom straw.

[0014] Furthermore, a limiting rod that penetrates the moving plate is fixedly connected to the top of the machine body, a stop block is fixedly connected to the top of the limiting rod, and the moving plate is slidably connected to the outside of the limiting rod.

[0017] Compared with the prior art, this utility model provides a dust removal and cleaning mechanism for the production of automotive protective films, which has the following beneficial effects:

[0018] 1. This dust removal and cleaning mechanism for automotive protective film production uses an electric telescopic cylinder to drive a moving plate to slide along a limit rod, which in turn drives the connecting rod, mounting plate, and two sets of top connecting plates to rise and fall synchronously. This adjusts the distance between the top and bottom suction pipes to meet the needs of different specifications of protective film. At the same time, the negative pressure fan in the cleaning mechanism generates negative pressure, which adsorbs impurities on both sides of the protective film through the conveying pipe and suction pipe. The baffle in the collection box can also easily clean the adsorbed impurities, effectively avoiding the problem of poor dust removal effect caused by the decrease in the viscosity of traditional adhesion rollers, and improving the stability and adaptability of dust removal.

[0019] 2. This dust removal and cleaning mechanism for automotive protective film production uses two electrostatic rollers inside the mounting housing to adsorb some impurities on the surface of the protective film. The dust extraction fan located at the top can further extract residual impurities. During the winding process, the dust extraction mechanism works continuously to ensure the high cleanliness of the protective film entering the winding box. At the same time, the cleaning mechanism cleans impurities in real time during the transmission of the protective film, comprehensively ensuring the dust removal and cleaning effect of the automotive protective film production process and improving product quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 3 This embodiment of a dust removal and cleaning mechanism for automotive protective film production includes a body 1, a winding box 2 fixedly connected to one side of the body 1, and a winding device 3 disposed on one side of the winding box 2. A dust suction mechanism 4 is disposed on the top of the body 1, a cleaning mechanism 5 for adsorbing impurities on both sides of the protective film is disposed on the outside of the body 1, and a lifting mechanism 6 for adjusting the lifting of the cleaning mechanism 5 is disposed on the top of the body 1.

[0026] The cleaning mechanism 5 includes a connecting plate 51 and a collection box 54 located outside the body 1. A suction pipe 52 is fixedly connected inside the connecting plate 51, and a negative pressure fan 55 is rotatably connected inside the collection box 54. A delivery pipe 56 is fixedly connected between the collection box 54 and the suction pipe 52.

[0027] Specifically, there are four sets of connecting plates 51 and two sets of straws 52, with the two sets of straws 52 arranged in a rectangular shape inside the four sets of connecting plates 51.

[0028] It should be noted that a corrugated pipe 53 is fixedly connected between the two sets of suction tubes 52, and a baffle 57 is slidably connected inside the collection box 54. The collection box 54 has a movable opening that matches the baffle 57. Negative pressure is generated by the negative pressure fan 55, and the suction tubes 52 are used to adsorb impurities on both sides of the protective film. The rectangular distribution of the suction tubes 52 can more comprehensively cover the surface of the protective film, improving the adsorption effect. The corrugated pipe 53 can adapt to the lifting and moving of the suction tubes 52, ensuring the continuity of adsorption, and the baffle 57 can easily clean the impurities inside the collection box 54, facilitating maintenance.

[0029] In this embodiment, the lifting mechanism 6 includes an electric telescopic cylinder 61 fixedly installed on the top of the machine body 1 and a movable plate 62 fixedly connected to the output end of the electric telescopic cylinder 61. A connecting rod 63 is fixedly connected to the bottom of the movable plate 62, and a mounting plate 64 is fixedly connected to the bottom end of the connecting rod 63. The connecting plate 51 is fixedly connected to the bottom of the mounting plate 64.

[0030] The two bottom connecting plates 51 are fixedly connected to the outside of the body 1, and the two top connecting plates 51 are fixedly connected to the bottom of the mounting plate 64. The top straw 52 is slidably connected to the outside of the body 1 via the moving plate 62 and is located on the upper surface of the bottom straw 52.

[0031] Specifically, a limiting rod 65 is fixedly connected to the top of the body 1, penetrating the movable plate 62. A stop block 66 is fixedly connected to the top of the limiting rod 65, and the movable plate 62 is slidably connected to the outside of the limiting rod 65. The movable plate 62 is driven to move up and down by an electric telescopic cylinder 61, which in turn drives the top suction pipe 52 to rise and fall. The distance between the suction pipe 52 and the protective film can be flexibly adjusted to meet the dust removal needs of protective films of different thicknesses. The limiting rod 65 and the stop block 66 ensure the stability of the movement of the movable plate 62.

[0032] In this embodiment, the dust collection mechanism 4 includes a mounting shell 41 fixedly connected to the top of the body 1. Two electrostatic rollers 43 are detachably connected inside the mounting shell 41. A cover plate is detachably connected to the top of the mounting shell 41, and a dust collection fan 42 is rotatably connected to the top of the cover plate, located on top of the two electrostatic rollers 43. When the dust collection fan 42 is working, and through the two electrostatic rollers 43, tiny impurities in the air inside the body 1 can be adsorbed. This, combined with the dust collection fan 42, achieves dual dust removal, preventing secondary contamination of the protective film by impurities. The detachable cover plate and electrostatic rollers 43 facilitate future maintenance and replacement.

[0033] The winding box 2 is externally hinged with a sealing plate, and the winding device 3 includes a drive motor fixedly installed outside the winding box 2, with a winding roller fixedly connected to the output shaft of the drive motor. The sealing plate outside the winding box 2 can prevent external impurities from entering, and the drive motor drives the winding roller to promptly wind up the protective film after dust removal.

[0034] The working principle of the above embodiments is as follows:

[0035] When the car protective film enters the dust removal and cleaning process, the position of the cleaning mechanism 5 is first adjusted by the lifting mechanism 6. The electric telescopic cylinder 61 drives the moving plate 62 to slide along the limit rod 65, causing the connecting rod 63, the mounting plate 64, and the two sets of connecting plates 51 at the top to move down, so that the top suction pipe 52 and the bottom suction pipe 52 are adapted to the thickness of the protective film. Then the cleaning mechanism 5 is started, and the negative pressure fan 55 generates negative pressure, which is transmitted to the two sets of suction pipes 52 through the delivery pipe 56. The rectangularly distributed suction pipes 52 adsorb impurities on both sides of the protective film, and the corrugated pipe 53 adapts to the position change of the suction pipes 52. To ensure continuous adsorption, impurities eventually enter the collection box 54. The baffle 57 can be pulled out for cleaning later. After the protective film enters the machine body 1, the dust collection mechanism 4 starts working. Two electrostatic rollers 43 first adsorb tiny impurities in the air inside the machine body 1, and then the dust collection fan 42 extracts the impurities, achieving double dust removal to avoid secondary pollution. The dust-removed protective film finally enters the winding box 2. The drive motor of the winding device 3 drives the winding roller to rotate and wind up the protective film. The sealing plate on the outside of the winding box 2 isolates external impurities to ensure that the protective film remains clean during the winding process.
