Description

Technical Field

[0001] This utility model belongs to the technical field of plastic film processing equipment, and in particular to a dust collection and purification device for plastic film production. Background Technology

[0002] During the film production process, dust easily adheres to the surface of the film, which can seriously affect other production stages. Therefore, it is necessary to clean the dust on the film surface. However, most existing cleaning methods involve brushing the film surface with a brush cleaning roller. This method causes dust on the film to adhere to the surface of the cleaning roller, and long-term use of the cleaning roller will result in excessive dust accumulation, which directly affects the cleaning effect of the film.

[0003] A search revealed a Chinese patent document (authorization announcement number CN222491110U) regarding a dust removal device for plastic film. The processing table has a dust removal component in the middle, comprising two second supports, two cleaning components, and multiple suction pipes. The two second supports are symmetrically fixed to the upper end of the processing table. The cleaning components include a motor and a cleaning shaft. The motor is fixed above the processing table; when the motor starts, it causes the cleaning shaft to rotate, thus brushing away dust and impurities on the plastic film. This method of dust removal for plastic film involves a cleaning roller with brushes rotating on the film and brushing up the dust, which is then sucked away by the suction pipes. While this method effectively removes dust from the film, long-term use leads to excessive dust accumulation on the cleaning roller, directly reducing the dust removal effect on the film surface. Therefore, a dust removal and purification device for plastic film production is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a dust collection and purification device for plastic film production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collection and purification device for plastic film production, comprising a base plate for installing a dust removal structure for plastic film and a cleaning roller for dust removal in plastic film production, wherein two drive rollers are fixedly installed on the top surface of the base plate, and vertical plates are symmetrically fixedly installed on the top surface of the base plate, and the cleaning roller is symmetrically rotated and installed between the two vertical plates.

[0006] A dust collection frame is fixedly installed between the two vertical plates, and the openings of the two dust collection frames extend to the outside of the two cleaning rollers respectively. A suction pipe is installed on the side wall of the dust collection frame.

[0007] Support rods are symmetrically fixedly installed on the top surface of the base plate, and hollow triangular plates are symmetrically fixedly installed between the two support rods. Air outlet pipes are connected to both sides of the equilateral sides of the two hollow triangular plates, and air supply pipes are connected to both side walls of the hollow triangular plates.

[0008] The top surface of the base plate is symmetrically fixed with a fixing plate, and the suction frame is fixedly installed on the opposite side of each of the two fixing plates.

[0009] Preferably, two strip grooves are symmetrically formed on the side of the base plate away from the drive roller, and sliders are slidably installed in the two strip grooves.

[0010] Preferably, mounting plates are fixedly installed on the top surfaces of both sliders, and extrusion rollers are symmetrically mounted between the two mounting plates.

[0011] Preferably, a crossbar is fixedly installed horizontally inside the strip groove, and the crossbar slides through the slider.

[0012] Preferably, a tension spring is fixedly installed between the inner wall of the strip groove and the side wall of the slider, and the tension spring is slidably sleeved to the outside of the crossbar.

[0013] Preferably, limit blocks are symmetrically fixedly installed on the sidewalls of the slider, and limit grooves are symmetrically formed on the inner wall of the strip groove.

[0014] Preferably, the two limiting blocks fixedly installed on the side wall of the slider are slidably connected to the inside of the two limiting grooves opened on the inner wall of the strip groove.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This dust collection and purification device for plastic film production benefits from the design of vertical plates, cleaning rollers, and dust collection frames. The two cleaning rollers can brush up the dust on the top and bottom sides of the plastic film. As the cleaning rollers clean the dust, the dust adhering to the outside of the cleaning rollers is then sucked away by the dust collection frames on the side walls of the cleaning rollers. This allows for timely cleaning of the cleaning rollers, preventing dust from accumulating on them and further improving the cleaning effect of the cleaning rollers.

[0017] This plastic film dust collection and purification device benefits from the design of a support rod, a hollow triangular plate, and an air outlet pipe. Air is introduced into the hollow triangular plate through an air duct, and then multiple air outlet pipes connected to the side wall of the hollow triangular plate spray the air out to the upper and lower sides of the plastic film, thereby blowing up the dust remaining on its side wall and further improving the dust cleaning effect of the plastic film.

[0018] This plastic film production dust collection and purification device, thanks to the setting of the fixed plate and two suction frames, can effectively prevent dust from falling back onto the surface of the film by sucking away the dust blown up by the air outlet pipe through the two suction frames.

[0019] This plastic film is used to produce a dust collection and purification device. Compared with existing technologies, this device can effectively and thoroughly clean the dust on the surface of the plastic film. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 4 The main structure of the dust collection and purification device for plastic film production shown is a base plate 1 for installing the dust removal structure of plastic film and a cleaning roller 5 for dust removal in plastic film production. Two drive rollers 3 are fixedly installed on the top surface of the base plate 1, and vertical plates 4 are symmetrically fixedly installed on the top surface of the base plate 1. The cleaning roller 5 is symmetrically rotated and installed between the two vertical plates 4. The outer wall of the cleaning roller 5 is provided with cleaning bristles.

[0031] A dust collection frame 6 is fixedly installed between the two vertical plates 4, and the openings of the two dust collection frames 6 extend to the outside of the two cleaning rollers 5 respectively. A suction pipe 7 is installed on the side wall of the dust collection frame 6. Thanks to the structure of the vertical plates 4, cleaning rollers 5 and dust collection frames 6, the dust on the upper and lower sides of the plastic film can be brushed up by the two cleaning rollers 5. As the cleaning rollers 5 clean the dust, the dust on the outside of the cleaning rollers 5 is then sucked away by the dust collection frame 6 on the side wall of the cleaning rollers 5. This enables timely cleaning of the cleaning rollers 5 to prevent dust from accumulating on the cleaning rollers 5, thereby further improving the cleaning effect of the cleaning rollers 5.

[0032] Support rods 8 are symmetrically fixedly installed on the top surface of the base plate 1. Hollow triangular plates 9 are symmetrically fixedly installed between the two support rods 8. Air outlet pipes 10 are connected to both sides of the equilateral sides of the two hollow triangular plates 9. Air supply pipes 11 are connected to the side walls of the hollow triangular plates 9. Thanks to the structure of the support rods 8, hollow triangular plates 9 and air outlet pipes 10, air is introduced into the interior of the hollow triangular plates 9 through the air supply pipes 11. Then, the air is sprayed out to the upper and lower sides of the plastic film through the multiple air outlet pipes 10 connected to the side walls of the hollow triangular plates 9, thereby blowing up the dust remaining on the side walls. This can further improve the dust cleaning effect of the plastic film. Moreover, since the air outlet pipes 10 on the hollow triangular plates 9 are all inclined towards the plastic film, the effect of blowing up the dust on the surface of the film by the air outlet pipes 10 can be effectively improved.

[0033] A fixing plate 2 is symmetrically fixedly installed on the top surface of the base plate 1, and a suction frame 12 is fixedly installed on each of the two fixing plates 2 on opposite sides. Thanks to the setting of the fixing plate 2 and the two suction frames 12, the dust blown up by the air outlet pipe 10 is sucked away by the two suction frames 12, thereby effectively preventing the dust from falling back onto the surface of the film.

[0034] Two strip grooves 15 are symmetrically formed on the side of the base plate 1 away from the drive roller 3. Slider 16 is slidably installed in the two strip grooves 15. Mounting plates 13 are fixedly installed on the top surface of the two sliders 16. Squeeze rollers 14 are symmetrically mounted between the two mounting plates 13. A crossbar 18 is fixedly installed horizontally in the strip grooves 15 and slides through the sliders 16. A tension spring 19 is fixedly installed between the inner wall of the strip grooves 15 and the side wall of the sliders 16 and slides onto the outside of the crossbar 18. When the plastic film is clamped between the two drive rollers 3 and the two squeeze rollers 14, the two tension springs 19 pull the two sliders 16, causing the two mounting plates 13 and the squeeze rollers 14 to move away from the drive roller 3. This can straighten the plastic film and improve the cleaning effect of the plastic film.

[0035] Limiting blocks 17 are symmetrically fixedly installed on the side wall of slider 16, and limiting grooves are symmetrically opened on the inner wall of strip groove 15. The two limiting blocks 17 fixedly installed on the side wall of slider 16 are slidably connected to the inside of the two limiting grooves opened on the inner wall of strip groove 15. Thanks to the setting of limiting blocks 17, the sliding direction of slider 16 can be effectively limited, and the stability of slider 16 and two extrusion rollers 14 during sliding can be further improved.

[0036] Working principle

[0037] This dust collection and purification device for plastic film production operates by first passing the plastic film to be dusted through two extrusion rollers 14, a cleaning roller 5, a hollow triangular plate 9, and a drive roller 3. Then, two tension springs 19 pull the slider 16 and the mounting plate 13 to move, causing the two extrusion rollers 14 to squeeze and pull the film, taut and facilitating dust removal. Next, the cleaning roller 5 rotates to brush up and clean the dust from the plastic film. The dust collection frame 6 on the cleaning roller 5 then sucks up the dust, improving its cleaning effect. Air is then introduced into the air duct 11 and the hollow triangular plate 9, and through multiple air outlet pipes 10 connected to its side wall, air is sprayed onto the surface of the plastic film, blowing up the dust. Simultaneously, the two suction frames 12 suck up the blown-up dust, preventing it from falling back onto the film surface.
