Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roller dust removal devices, in particular to a dust removal device for a pre-coating film production roller. Background Art
[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film before laminating it with paper printed products. The pre-coating factory first applies glue on the film according to the specifications and format, then rewinds it for the user to choose, and then laminates it with the printed product. Laminating, also known as film pasting, is the processing technology of coating plastic film with adhesive, and bonding it with paper printed products after heating and pressurizing to form a paper-plastic integrated product.
[0003] During the production process of pre-coated film, such as during transportation, there may be dust on the film surface and the roller. In addition, during the contact between the film and the drum, a certain amount of static electricity will be generated due to friction, and dust will be more likely to accumulate and adhere to the production roller, which may cause extrusion scratches on the surface of the pre-coated film or affect its quality. Utility Model Content
[0004] The utility model aims to provide a dust removal device for a pre-coating film production roller to remove dust on the production roller, remove static electricity and avoid excessive particle accumulation.

[0006] Furthermore, it also includes an immersion-type adhesion roller, which is arranged on the upper side of the roller and is in contact with the surface of the roller; the outside of the immersion-type adhesion roller is wrapped with a liquid-absorbing sponge.
[0007] Furthermore, two ends of the roller are rotatably connected with support plates, and the support plates are connected with grounding wires.
[0008] Furthermore, a wind wheel cylinder is coaxially provided at one end of the roller, the ventilation duct is connected to a side wind duct, and the air outlet of the side wind duct is aligned with the wind wheel cylinder; the air outlet direction of the side wind duct is kept coincident with the tangent direction of the wind wheel cylinder.
[0009] Furthermore, it also includes a traction assembly arranged at the rear end of the roller, and the traction assembly includes traction rollers arranged in pairs, and a film-passing gap is left between the two traction rollers.
[0010] The technical solution of the embodiments of the utility model has at least the following advantages and beneficial effects: the utility model separates most of the dust from the film surface by neutralizing the charge carried by the dust through the charged wind blown out by the ion blower cover, and further brushes the dust on the roller surface through the cleaning brush plate, thereby removing static electricity, making the particle dust easier to clean, ensuring the cleanliness of the pre-coated film surface, and avoiding defects that may be caused by contact and extrusion between the film surface and the roller surface due to the presence of dust particles.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example
[0020] The following is further described in conjunction with specific embodiments. Figure 1-Figure 3 As shown, this embodiment is a dust removal device for a pre-coated film production roller, including a roller 2 and a mounting bracket 1, the front end of the mounting bracket 1 is hoisted with an ion fan cover 3 arranged on the upper side of the pre-coated film, and the top of the ion fan cover 3 is connected to a ventilation pipe 4; the roller 2 is arranged at the rear end of the ion fan cover 3, and a cleaning brush plate 6 parallel to it is provided on the side of the roller 2, and a dust collecting box 7 is provided under the cleaning brush plate 6; specifically, the wind with positive and negative ions is first blown out through the ion fan cover 3 to neutralize the dust on the surface of the film and the charge carried by the film surface, release the adsorption force, and blow away most of the dust particles on the pre-coated film. When the pre-coated film moves to the roller 2, a part of the particles will further adhere to the surface of the roller 2, and the cleaning brush plate 6 can brush them off and drop them into the dust collecting box 7 for collection, thereby achieving the effect of removing the dust particles on the pre-coated film and the roller 2, thereby ensuring the production quality of the pre-coated film.
[0021] The present embodiment further comprises an immersion-type adhesion roller 9, which is arranged on the upper side of the roller 2 and is in contact with the surface of the roller 2; the outside of the immersion-type adhesion roller 9 is wrapped with a liquid-absorbing sponge 91; specifically, after the roller 2 is processed again by the cleaning brush plate 6, there may still be some particles of dust that are too tightly adsorbed on the roller 2, and the liquid-absorbing sponge 91 can be wetted with alcohol or water to improve the adhesion and dust removal ability, so that the roller 2 is cleaned more cleanly. At the same time, the surface of the roller 2 has a certain humidity, which reduces the ability to generate static electricity.
[0022] like Figure 1 As shown, support plates 21 are rotatably connected at both ends of the roller 2, and the support plates 21 are connected to grounding wires 22, which eliminate the accumulation of static charges by connecting the device to the ground and sending electrons to the ground, which has a promoting effect on reducing the adhesion of particulate dust.
[0023] like Figure 1 , Figure 2 and Figure 3As shown, a wind wheel cylinder 23 is coaxially provided at one end of the roller 2 in this embodiment, and the ventilation pipe 4 is connected to the side wind duct 5, and the air outlet of the side wind duct 5 is aligned with the wind wheel cylinder 23; the air outlet direction of the side wind duct 5 coincides with the tangent direction of the wind wheel cylinder 23; specifically, during the continuous movement of the pre-coated film, there will be a certain friction between the pre-coated film and the roller 2, so that the roller 2 has a certain rotation speed, and on this basis, in order to provide auxiliary rotation power to the roller 2 to overcome the resistance of the cleaning brush plate 6, the wind blown out by the side wind tube drives the wind wheel cylinder 23 to rotate, thereby synchronously driving the roller 2 to rotate.
[0024] The present embodiment further includes a traction assembly 8 disposed at the rear end of the roller 2. The traction assembly 8 includes traction rollers 81 disposed in pairs, and a film-passing gap is left between the two traction rollers 81. Specifically, the pre-coated film is driven to move continuously by the traction rollers 81 to ensure contact between the pre-coated film and the roller 2, thereby effectively removing particulate dust.
[0025] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
