[0002] Patent CN203991371U discloses a double-sided dust removal device for BOPP film, which includes a support frame disposed between a flattening roller and a take-up roller. The support frame is equipped with an upper dust removal roller and a lower dust removal roller. Both the upper and lower dust removal rollers have multiple layers of dust collection paper that can be peeled off layer by layer. An electrostatic eliminator is provided in front of the upper and lower dust removal rollers. A pair of gas springs are also fixedly connected to the support frame. One end of the gas spring has a bearing, and the pair of bearings are sleeved on both ends of the shaft of the upper dust removal roller. The gas springs provide elastic force to the upper dust removal roller to control the height of the upper dust removal roller. The lower dust removal roller is connected to a motor.

[0003] Although the upper and lower dust removal rollers achieve double-sided dust removal, dust adheres to the surface of the rollers after a period of use, which not only reduces the dust removal effect but may also cause the adhered dust to fall off and contaminate the film material. This results in the disadvantages of short service life and poor dust removal effect. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides a double-sided dust removal device for feeding, referring to... Figure 1-4The system includes a first frame 1 and a second frame 2, connected by a connector 3. The first frame 1 has a rotatably connected upper dust removal roller 11, and the second frame 2 has a rotatably connected lower dust removal roller 21. The upper dust removal roller 11 and the lower dust removal roller 21 are used to roll and clamp materials as they pass through. The first frame 1 also has a rotatably connected upper adhesive roller 12, which contacts the upper dust removal roller 11, and the adhesiveness of the upper adhesive roller 12 is greater than that of the upper dust removal roller 11. The second frame 2 has a rotatably connected lower adhesive roller 22, which contacts the lower dust removal roller 21, and the adhesiveness of the lower adhesive roller 22 is greater than that of the lower dust removal roller 21. By setting up upper dust removal roller 11 and lower dust removal roller 21, dust removal can be performed on both the upper and lower surfaces of the material simultaneously, improving dust removal efficiency. Simultaneously, the upper and lower adhesive rollers 12 and 22 have greater adhesion than their corresponding dust removal rollers, thus transferring dust adhering to the upper and lower dust removal rollers to the corresponding rollers, preventing dust from re-contaminating the material and effectively improving the dust removal effect. Specifically, upper dust removal roller 11 and lower dust removal roller 21 are dust removal rubber rollers, while upper adhesive roller 12 and lower adhesive roller 22 are tearable dust removal paper rolls. When a certain amount of dust accumulates on the dust removal paper, the surface dust removal paper can be torn off to expose the next layer of dust-free dust removal paper, allowing continued high dust removal efficiency.

[0026] As a preferred embodiment, the connector 3 includes: a hinge 31 hinged between the first frame 1 and the second frame 2, and a gas spring hydraulic rod 32 rotatably connected between the first frame 1 and the second frame 2. The first frame 1 is hinged to the second frame 2 via the hinge 31. When threading materials, the first frame 1 can be directly lifted, leaving more operating space between the upper dust removal roller 11 and the lower dust removal roller 21. The gas spring hydraulic rod 32 can provide a certain supporting force to support the first frame 1, facilitating material threading and improving work efficiency.

[0027] As a preferred embodiment, the first frame 1 is provided with a first pull-out slide rail 13, through which the upper dust-removing roller 12 is installed into the first frame 1; the second frame 2 is provided with a second pull-out slide rail 23, through which the lower dust-removing roller 22 is installed into the second frame 2. By setting the first pull-out slide rail 13 and the second pull-out slide rail 23, when it is necessary to replace or remove the dust-removing paper, the upper dust-removing roller 12 or the lower dust-removing roller 22 can be directly pulled out for easy replacement.

[0028] As a preferred embodiment, the first pull-out slide rail 13 is provided with a first sliding bracket 14, and the end of the upper dust-adhesive roller 12 is provided with a first slider 15 that is slidably connected to the first sliding bracket 14. The upper dust-adhesive roller 12 and the first slider 15 are connected by a bearing, thereby realizing the rotational connection of the upper dust-adhesive roller 12 in the first frame 1. The first frame 1 is provided with a first pressing drive 16 for pushing the first slider 15 to move in the first sliding bracket 14. The first pressing drive 16 pushes the upper dust-adhesive roller 12 to contact the surface of the upper dust-removing roller 11. The second pull-out slide rail 23 is provided with a second sliding bracket 24, and the end of the lower dust-adhesive roller 22 is provided with a second slider 25 that is slidably connected to the second sliding bracket 24. The lower dust-adhesive roller 22 and the second slider 25 are connected by a bearing, thereby realizing the rotational connection of the lower dust-adhesive roller 22 in the second frame 2. The second frame 2 is provided with a second pressing drive 26 for pushing the second slider 25 to move in the second sliding bracket 24. The second pressing drive 26 pushes the lower dust-adhesive roller 22 to contact the surface of the lower dust-removing roller 21. By setting up a first sliding bracket 14, a first slider 15, a first pressing drive 16, a second sliding bracket 24, a second slider 25, and a second pressing drive 26, the automatic pressing of the upper dust-adhesive roller 12 and the lower dust-adhesive roller 22 with the corresponding dust-removing roller can be realized, ensuring good contact between the dust-adhesive roller and the dust-removing roller, improving the stability of the dust removal effect, and reducing manual operation, thereby improving work efficiency.

[0029] As a preferred embodiment, the first pressing drive component 16 and the second pressing drive component 26 are cylinders. One end of the cylinder of the first frame 1 is fixed to the top of the first frame 1, and its telescopic end abuts downward against the top of the first slider 15; one end of the cylinder of the second frame 2 is fixed to the bottom of the second frame 2, and its telescopic end abuts upward against the bottom of the second slider 25. Using cylinders as pressing drive components can provide stable pressing force, ensuring close contact between the upper dust-adhesive roller 12 and the lower dust-adhesive roller 22 and the corresponding dust-removing rollers, further improving the dust removal effect. At the same time, cylinders have a simple structure, low cost, and are easy to control, making them convenient for application in actual production.

[0030] As a preferred embodiment, the first sliding bracket 14 is provided with a first pull handle 17, and the second sliding bracket 24 is provided with a second pull handle 27. By providing the first pull handle 17 and the second pull handle 27, it is convenient for operators to pull out the upper dust roller 12 and the lower dust roller 22, thereby realizing the extraction and insertion of the dust rollers, further improving the convenience of operation, and facilitating the replacement and maintenance of the dust rollers.

[0031] As a preferred embodiment, two upper dust removal rollers 11 are spaced apart, with the upper dust-adhesive roller 12 corresponding to the space between the two upper dust removal rollers 11; two lower dust removal rollers 21 are spaced apart, with the lower dust-adhesive roller 22 corresponding to the space between the two lower dust removal rollers 21. By setting two upper dust removal rollers 11 and two lower dust removal rollers 21, and upper dust-adhesive rollers 12 and lower dust-adhesive rollers 22 with corresponding gaps, the dust removal effect can be further improved. When the material passes through the two dust removal rollers, it can receive more thorough dust removal treatment, and at the same time, the dust-adhesive rollers can better adsorb the dust on the dust removal rollers, effectively preventing dust from re-contaminating the material.

[0032] As a preferred embodiment, the first frame 1 has first outer plates 18 on both sides, and the second frame 2 has second outer plates 28 on both sides, with a gap between the first outer plates 18 and the second outer plates 28 for materials to pass through. The first outer plates 18 and the second outer plates 28 serve to accommodate the installation of the first pull-out slide rail 13 and the second pull-out slide rail 23, and also prevent foreign objects from accidentally entering the frame and affecting the dust removal effect of the dust removal roller, thus providing dust protection.
