Description
Technical Field
[0001] The utility model relates to the technical field of dust removal of PET protective films, in particular to a dust removal device for the surface of a PET protective film. Background Art
[0002] PET protective film is a high-performance protective film material based on polyethylene terephthalate. Currently, during the production process, a large amount of dust accumulates on the surface of the protective film, affecting the product's appearance and hindering its sales. Therefore, dust removal is necessary during the production process.
[0003] The existing PET protective film surface dust removal device uses a conveying mechanism to transport the PET protective film to between cleaning rollers, and then uses the cleaning rollers to clean the dust on the surface of the PET protective film. However, since the PET protective film may be wrinkled or wavy during the transportation process, when it moves to the cleaning rollers, it is easy to cause the dust at the wrinkled and deformed areas to not be cleaned properly, which is quite inconvenient.
[0004] Therefore, a PET protective film surface dust removal device has been developed that can press the PET protective film, eliminate wrinkles or wavy deformation of the PET protective film, ensure the smoothness of the film surface, and avoid affecting the dust removal effect of the PET protective film. Utility Model Content
[0005] In order to overcome the disadvantages of the existing PET protective film surface dust removal device, the PET protective film may produce wrinkles or wave-like deformations during the transportation process, which may easily lead to the dust in the wrinkles not being cleaned properly when moving to the cleaning roller, which is relatively inconvenient. The utility model provides a PET protective film surface dust removal device which can press the PET protective film, eliminate the wrinkles or wave-like deformation of the PET protective film, ensure the smoothness of the film surface, and avoid affecting the dust removal effect of the PET protective film.
[0006] The technical solution is: a PET protective film surface dust removal device, including a base frame, a flat frame, ball columns, a lifting roller, a dust removal component and a pressing mechanism. The upper side of the base frame is connected to the flat frame, and the upper sides of the front and rear parts of the flat frame are both slidably connected to the left and right ball columns. The two laterally adjacent ball columns are rotatably connected to the lifting roller. The flat frame is provided with a dust removal component and a pressing mechanism that can press the PET protective film.
[0007] As a further preferred solution, a compression spring is also included, and a compression spring is connected between the ball column and the flat frame.
[0008] As a further preferred solution, the dust removal assembly includes an upper frame, a cleaning roller and an electrostatic adsorption plate. The upper frame is connected to the upper rear side of the base frame, and the upper frame is located in front of the rear ball column. The upper part of the upper frame is rotatably connected to two upper and lower cleaning rollers, and the front and rear sides of the upper frame are connected to two upper and lower electrostatic adsorption plates.
[0009] As a further preferred solution, the pressing mechanism includes an end seat, a fixed roller, a rotating roller and a pressing roller. The upper sides of the left and right parts of the flat frame are connected to the front and rear end seats, the lower parts of the two laterally adjacent end seats are connected to the fixed roller, the upper part of the right end seat is rotatably connected to the rotating roller, and the fixed roller and the rotating roller are rotatably connected to the pressing roller.
[0010] As a further preferred solution, a lock is also included. The left part of the rotating roller is rotatably connected with a lock, and the lock is engaged with the adjacent fixed roller.
[0011] As a further preferred solution, it also includes a feeding mechanism, which includes an organic base, a motor and a feeding roller. The organic base is connected to the upper left side of the flat frame, and the base is located between the two end seats on the left. The upper part of the end seat is connected to the motor, and the feeding roller is connected to the motor output shaft. A connecting sleeve is provided between the end seats on the right, and the feeding roller is rotatably connected to the connecting sleeve.
[0012] The utility model has the following advantages: 1. The utility model places the protective film between the fixed roller and the rotating roller, then rotates the rotating roller to reset, and then re-engages the lock with the fixed roller, so that the protective film is pressed between the pressing rollers. While the protective film moves, the pressing roller is driven to rotate, thereby achieving the effect of pressing the PET protective film, eliminating wrinkles or wavy deformation of the PET protective film, ensuring the smoothness of the film surface, and avoiding affecting the dust removal effect of the PET protective film.
[0013] 2. The utility model starts the motor on the machine base to drive the feed roller to rotate, so that the feed roller contacts the protective film and pushes the protective film to move, thereby achieving the effect of feeding the protective film and allowing the protective film to pass smoothly.

[0020] A PET protective film surface dust removal device, such as Figure 1 and Figure 2 As shown, it includes a base frame 1, a flat frame 2, a compression spring 3, a ball column 4, a lifting roller 5, a dust removal component and a pressing mechanism 9. The upper side of the base frame 1 is connected to the flat frame 2, and the ball columns 4 are connected to the flat frame 2 with a compression spring 3. The upper sides of the front and rear parts of the flat frame 2 are both slidably connected to the left and right ball columns 4, and the two laterally adjacent ball columns 4 are rotatably connected to the lifting roller 5. The flat frame 2 is provided with a dust removal component and a pressing mechanism 9.
[0021] like Figure 1 and Figure 2 As shown, the dust removal assembly includes an upper frame 6, a cleaning roller 7 and an electrostatic adsorption plate 8. The upper frame 6 is connected to the upper rear side of the base frame 1, and the upper frame 6 is located in front of the rear ball column 4. The upper part of the upper frame 6 is rotatably connected to the upper and lower cleaning rollers 7, and the upper and lower electrostatic adsorption plates 8 are connected to the front and rear sides of the upper frame 6.
[0022] like Figure 1 and Figure 3 As shown, the pressing mechanism 9 includes an end seat 91, a fixed roller 92, a rotating roller 93, a pressing roller 94 and a lock 95. The upper sides of the left and right parts of the flat frame 2 are connected to the front and rear end seats 91, and the lower parts of the two laterally adjacent end seats 91 are connected. The upper part of the right end seat 91 is rotatably connected to the rotating roller 93, and the fixed roller 92 and the rotating roller 93 are rotatably connected to the pressing roller 94. The left part of the rotating roller 93 is rotatably connected to the lock 95, and the lock 95 is engaged with the adjacent fixed roller 92.
[0023] When using the utility model, first place the base frame 1 in the dust removal area of the PET protective film, then pass the PET protective film around the upper side of the front lifting roller 5, then pass it between the cleaning roller 7 and the electrostatic adsorption plate 8, and finally pass the PET protective film around the upper side of the rear lifting roller 5. Through the force of the compression spring 3, the lifting roller 5 is always in contact with the PET protective film, so that the PET protective film is kept taut, and then the PET protective film is moved so that the electrostatic adsorption plate 8 adsorbs the dust on the PET protective film, and the cleaning roller 7 cleans the dust on the PET protective film. The protective film passes through the cleaning roller 7 and When the protective film is between the electrostatic adsorption plates 8, the lock 95 is rotated to disengage the lock 95 from the fixed roller 92, and then the rotating roller 93 is rotated away from the fixed roller 92, so that the protective film is located between the fixed roller 92 and the rotating roller 93, and then the rotating roller 93 is rotated and reset, and the lock 95 is re-engaged with the fixed roller 92, so that the protective film is pressed between the pressing rollers 94. When the protective film moves, the pressing rollers 94 are driven to rotate, thereby pressing the PET protective film, eliminating wrinkles or wavy deformations of the PET protective film, ensuring a smooth surface of the film material, and avoiding affecting the dust removal effect of the PET protective film.
[0024] like Figure 1 and Figure 4 As shown, it also includes a feeding mechanism 10, which includes an organic base 101, a motor 102 and a feeding roller 103.
