Description

Technical Field

[0001] This utility model relates to equipment for plastic film production, specifically to a dust removal device for plastic film production. Background Technology

[0002] Plastic packaging and plastic packaging products are taking up an increasingly larger share of the market, especially composite plastic packaging, which is now widely used in the food, pharmaceutical, and chemical industries. Chinese patent application number CN202222799891.4 discloses a dust removal device for plastic film production, comprising: a dust removal box, a cleaning chamber connected to the dust removal box with two symmetrical sliding grooves on the dust removal box, a conveying component rotatably connected to one side of the upper end of the dust removal box, a receiving component rotatably connected to the other side of the upper end of the dust removal box, a film body connected between the conveying component and the receiving component, a water spraying mechanism connected to the dust removal box, a scraping mechanism slidably connected inside the cleaning chamber, a drain pipe connected to the end of the dust removal box away from the conveying component, and two symmetrical follower shafts rotatably connected to the inner wall of the cleaning chamber, with contact rollers connected to the outer periphery of the follower shafts, the contact rollers abutting against the film body; however, this device still has the following problems in use: 1) The device cleans the dust on the film by scraping, but during cleaning, friction is generated between the scraper and the film, causing the dust to still adhere to the film, resulting in poor cleaning effect; 2) During the cleaning process, the scraper will scrape off the dust on the film, but the dust will accumulate, making subsequent scraping increasingly difficult. Utility Model Content

[0003] To address the shortcomings of existing technologies, this application provides a dust removal device for plastic film production. This dust removal device for plastic film production employs a specific structure, using a conductive rubber roller as a dust collecting electrode to adsorb dust from the film, thereby cleaning the dust from the film surface. Simultaneously, a fan is used to remove dust from inside the dust collection chamber, improving the overall dust removal efficiency of the film.

[0004] The technical solution of this application is as follows:

[0005] A dust removal device for plastic film production includes a dust removal box. A drive box is fixedly connected to the rear side of the dust removal box, and support plates are fixedly connected to both the left and right sides. A winding motor is fixedly connected to the dust removal box, and a connecting rod is fixedly connected to the output end of the winding motor. The dust removal box has openings on both the front and rear sides, and a sliding rod is fixedly connected to each opening on both sides. A slider is slidably connected to the sliding rod, and a pressure roller is rotatably connected between the sliders on both sides. The dust removal box has inlet and outlet ports on both the left and right sides, and guide rollers are rotatably connected to each inlet and outlet port on both sides. A conductive rubber roller is rotatably connected to the middle position inside the dust removal box. There are several conductive rubber rollers located on both sides of the film. An exhaust fan is fixedly connected to the bottom of the dust removal box below the conductive rubber rollers.

[0006] Compared with the prior art, the dust removal device for plastic film production of this application, during use, first passes the film through the upper side of the guide roller at the left inlet / outlet, then through the lower side of the pressure roller, then through the conductive rubber roller, and finally out through the right pressure roller and outlet. Under the action of the pressure roller, it is easy to adjust the tension of the film. When the film passes through the conductive rubber roller, it is energized, so that the conductive rubber roller acts as a dust collecting electrode, adsorbing the dust on the film, thereby completing the cleaning of the film. During the cleaning process, the exhaust fan is started, and under the action of the exhaust fan, the dust inside the dust removal box is sucked out, which facilitates the removal of dust inside the dust removal box and prevents the film from adsorbing dust again in the dust removal box, thus improving the overall dust removal effect of the film.

[0007] As an optimization, in the aforementioned dust removal device for plastic film production, a baffle is installed in the opening at the front of the dust removal box, and a brush is fixedly connected in the opening at the rear of the dust removal box. The brush is located on the left and right sides of the opening, with a gap in the middle. The brush prevents dust from entering the dust removal box from the opening, and the gap in the middle allows the positioning block to move the slider up and down, facilitating the adjustment of the pressure roller.

[0008] As an optimization, in the aforementioned dust removal device for plastic film production, a positioning block is provided on the slider located at the rear of the dust removal box. A rubber pad is fixedly connected to the inner side of the positioning block, and the positioning block is fixedly connected to the slider by bolts. Under the action of the rubber pad, the friction between the positioning block and the dust removal box is increased, thereby enhancing the stability of the positioning block and the pressure roller.

[0009] As an optimization, in the aforementioned dust removal device for plastic film production, there are two rubber pads, which are in contact with the dust removal boxes on both sides of the opening.

[0010] As an optimization, in the aforementioned dust removal device for plastic film production, the drive box has a hinged door on its outside and a high-voltage device inside, which provides voltage to the conductive rubber roller. Under the action of the drive box, the conductive rubber roller is energized, forming a clamping electric field on both sides of the film, enhancing dust adsorption efficiency. The conductive rubber roller is made of flexible conductive material, adhering to the film surface to ensure a uniform electric field distribution. It is important to avoid excessive voltage that could cause film breakdown or aging, and to ensure that the equipment temperature remains below the film's melting point.

[0011] As an optimization, in the aforementioned dust removal device for plastic film production, a cover plate is hinged to the upper side of the dust removal box, and a limiting block is fixedly connected to the side wall of the dust removal box located below the cover plate. The cover plate facilitates subsequent cleaning and maintenance of the interior of the dust removal box.

[0012] As an optimization, in the aforementioned dust removal device for plastic film production, the bottom of the dust collection box is fixedly connected to four support legs, which are evenly distributed. The support legs elevate the dust collection box, allowing a dust collection bag to be placed at its bottom for easy collection of dust from the box. Attached Figure Description

Detailed Implementation

[0019] The present application will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present application.

[0020] Example (see) Figures 1-5 ):

[0021] A dust removal device for plastic film production includes a dust removal box 1. A drive box 2 is fixedly connected to the rear side of the dust removal box 1, and support plates 3 are fixedly connected to both the left and right sides. A winding motor 4 is fixedly connected to the dust removal box 3, and a connecting rod 41 is fixedly connected to the output end of the winding motor 4. The dust removal box 1 has openings 5 ​​on both the front and rear sides, and a sliding rod 6 is fixedly connected to each of the openings 5 ​​on both sides. A slider 7 is slidably connected to the sliding rod 6, and a pressure roller 18 is rotatably connected between the sliders 7 on both sides. The dust removal box 1 has inlet and outlet ports 11 on both the left and right sides, and a guide roller 12 is rotatably connected to each of the inlet and outlet ports 11 on both sides. A conductive rubber roller 10 is rotatably connected to the middle position inside the dust removal box 1. There are two conductive rubber rollers 10, located on both sides of the film. An exhaust fan 14 is fixedly connected to the bottom of the dust removal box 1, located below the conductive rubber rollers 10. During use, the film is first passed through the guide roller 12 on the left side of the inlet / outlet 11, then through the pressure roller 18, then through the conductive rubber roller 10, and finally out through the right pressure roller 18 and outlet 11. Under the action of the pressure roller 18, the tension of the film can be easily adjusted. When the film passes through the conductive rubber roller 10, it is energized so that the conductive rubber roller 10 acts as a dust collecting electrode to adsorb the dust on the film, thereby completing the cleaning of the film. During the cleaning process, the exhaust fan 14 is started. Under the action of the exhaust fan 14, the dust inside the dust collection box 1 is sucked out, which facilitates the removal of dust inside the dust collection box 1 and prevents the film from adsorbing dust again in the dust collection box 1, thus improving the overall dust removal effect of the film.

[0022] In this embodiment, a baffle 9 is installed in the opening 5 on the front side of the dust collection box 1, and a brush 13 is fixedly connected in the opening 5 on the rear side of the dust collection box 1. The brush 13 is located on the left and right sides of the opening 5, with a gap in the middle. Under the action of the brush 13, dust is prevented from entering the dust collection box 1 from the opening 5. At the same time, the gap in the middle allows the positioning block 8 to drive the slider 7 to move up and down, which facilitates the adjustment of the pressure roller 18.

[0023] In this embodiment, a positioning block 8 is provided on the slider 7 located on the rear side of the dust collection box 1. A rubber pad 81 is fixedly connected to the inner side of the positioning block 8, and the positioning block 8 is fixedly connected to the slider 7 by bolts. Under the action of the rubber pad 81, the friction between the positioning block 8 and the dust collection box 1 is increased, thereby enhancing the stability of the positioning block 8 and the pressure roller 18.

[0024] In this embodiment, there are two rubber pads 81, which are in contact with the dust collection boxes 1 on both sides of the opening 5.

[0025] In this embodiment, the drive box 2 is hinged to a door 21 on its outer side and has a high-voltage device inside, which provides voltage to the conductive rubber roller 10. Under the action of the drive box 2, the conductive rubber roller 10 is energized, forming a clamping electric field on both sides of the film, enhancing the dust adsorption efficiency. The conductive rubber roller 10 is a flexible conductive material that adheres to the film surface, ensuring a uniform distribution of the electric field. It is important to avoid excessive voltage that could cause film breakdown or aging, and to ensure that the equipment temperature is below the film's melting point (e.g., approximately 250°C for PET).

[0026] In this embodiment, a cover plate 15 is hinged to the upper side of the dust collection box 1, and a limiting block 16 is fixedly connected to the side wall of the dust collection box 1 located below the cover plate 15. The cover plate 15 facilitates subsequent cleaning and maintenance of the interior of the dust collection box 1.

[0027] In this embodiment, four support legs 17 are fixedly connected to the bottom of the dust collection box 1, and they are evenly distributed. The support legs 17 support the dust collection box 1, allowing a dust collection bag to be placed at the bottom for easy collection of dust from the dust collection box 1.

[0028] In this embodiment of the dust removal device for plastic film production, when cleaning the entire equipment, the conductive rubber roller 10 is first de-energized and stopped working, and the exhaust fan 14 is started. Then, the cover plate 15 is opened to clean the dust on the conductive rubber roller 10 and let it fall to the bottom of the dust collection box 1. Since the bottom of the dust collection box 1 is set in an inverted cone shape, the dust can be better sucked into the dust collection bag from the exhaust fan 14, which is convenient for cleaning and maintenance.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
