Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, specifically to a dust removal device for polyimide film production. Background Technology
[0002] During the production process of polyimide film, dust will inevitably adhere to the surface of the film due to the working environment. If the dust on the surface of the polyimide film is not removed in time, it will affect the processing quality of the film and thus reduce the film's performance.
[0003] A search revealed existing technology (publication number: CN212633528U), which describes "a dust removal device for polyimide film production, comprising a housing, with support legs bolted to all four sides of the bottom of the housing, an observation window at the bottom of the front of the housing, a controller bolted to the center of the top of the front of the housing, and a fixing plate vertically bolted to the right side of the top of the inner cavity of the housing." This invention, through the combination of a dust pump, filter bag, connecting pipe, T-joint, hose, and suction head, can adsorb dust on the surface of polyimide film and airborne dust particles. Through the combination of an electric telescopic rod, moving plate, dust removal roller, and soft bristles, it can clean stubborn dust adhering to the surface of the polyimide film, preventing stubborn dust from remaining on the polyimide film surface and improving the dust removal efficiency of the polyimide film. With the assistance of an electrostatic precipitator, it can electrostatically remove dust from the surface of the polyimide film.
[0004] Although existing dust removal devices for polyimide film production have achieved dust removal, they still have some shortcomings: the existing dust removal devices can only remove dust from one side of the polyimide film, resulting in incomplete dust removal; secondly, the polyimide film after dust removal generates static electricity during the guide roller conveying process, which leads to the re-adsorption of dust from the air, resulting in poor dust removal effect. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, a dust removal device for polyimide film production is provided to solve the problems that existing dust removal devices for polyimide film production still have poor dust removal effect and incomplete dust removal.
[0006] To achieve the above objectives, a dust removal device for polyimide film production is provided, comprising: a dust removal box for polyimide film production, wherein a first guide roller and a second guide roller are provided inside the dust removal box, a vacuum cleaner is provided on the upper side of the dust removal box, and a double-sided dust removal assembly is connected to the outer side of the vacuum cleaner, and the double-sided dust removal assembly is located inside the dust removal box for polyimide film production. The double-sided dust removal assembly includes an upper hollow plate and a lower hollow plate, and two dust removal rollers are provided between the upper and lower hollow plates, and a dust suction head is provided on the outer side of the dust removal rollers. An air guide assembly is provided inside the dust removal box for polyimide film production, and an ion fan is connected to the outer side of the air guide assembly.
[0007] Furthermore, the vacuum cleaner has a dust filter bag connected to its suction side, and a suction pipe is connected to the outside of the dust filter bag. The suction pipe is inserted into the dust collection box used for polyimide film production and connected to the upper hollow plate.
[0008] Furthermore, the upper hollow plate and the lower hollow plate are arranged parallel to each other, and the upper hollow plate and the lower hollow plate are connected by a connecting pipe provided at the outer end.
[0009] Furthermore, the dust removal roller is rotatably connected to both ends with side plates, and the side plates are fixed between the upper hollow plate and the lower hollow plate, and the side plates are located inside the connecting pipe.
[0010] Furthermore, the suction head is located on both sides of the dust removal roller, and the outer wall of the suction head is connected to a first branch pipe, which is connected to the upper hollow plate and the lower hollow plate respectively.
[0011] Furthermore, the ion fan is installed on the upper part of the dust collection box for polyimide film production, and the air outlet of the ion fan is connected to an air outlet pipe, which is inserted into the interior of the dust collection box for polyimide film production. At the same time, a second branch pipe is connected to the lower end of the air outlet pipe through a T-joint.
[0012] Furthermore, the air guide assembly includes an air guide frame, and the inner wall of the air guide frame is provided with an upper flow hole and a lower flow hole. An upper air outlet is provided on the lower side of the upper flow hole, and a lower air outlet is provided on the upper side of the lower flow hole. At the same time, the upper air outlet and the lower air outlet are opposite each other.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By utilizing the first and second guide rollers inside the dust collection box for polyimide film production, the polyimide film is introduced from one side of the dust collection box and led out from the other side. At the same time, the film passes through the dust collection roller and the inside of the air guide frame. At this time, a vacuum cleaner is used to draw air from the upper and lower hollow plates. Then, through the first branch pipe and the dust suction head, the dust on the outside of the dust collection roller is sucked up. At the same time, the soft lint outside the dust collection roller and the dust on both sides of the film are cleaned, thereby achieving the effect of double-sided dust removal of the film and improving the comprehensiveness of dust removal.
[0015] 2. Using an ion fan, an air outlet pipe, a three-way fitting, and a second branch pipe, and then through an air guide frame, air is blown onto the top and bottom of the film passing through the inside of the air guide frame through the upper and lower air outlets. The charged ion air eliminates the static electricity generated by the friction between the film and the guide roller, thereby preventing the re-adsorption of dust from the air during subsequent conveying, achieving a good dust removal effect.

[0025] Specifically, the outer wall of the dust removal roller 37 is provided with soft bristles.
[0026] like Figures 1 to 3 In the process, a dust filter bag 21 is connected to the suction side of the vacuum cleaner 2, and a suction pipe 22 is connected to the outside of the dust filter bag 21. The suction pipe 22 is inserted into the dust removal box 1 for polyimide film production and connected to the upper hollow plate 31. The upper hollow plate 31 and the lower hollow plate 32 are arranged parallel to each other, and the upper hollow plate 31 and the lower hollow plate 32 are connected to each other through a connecting pipe 33 at the outer end. The two ends of the dust removal roller 37 are rotatably connected to side plates 34, and the side plates 34 are fixed between the upper hollow plate 31 and the lower hollow plate 32. The side plates 34 are located inside the connecting pipe 33.
