Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for protective film production. Background Art

[0002] During the production of protective film, the dust on the surface of the protective film needs to be cleaned by a dust removal device before packaging. According to the patent authorization announcement number: CN217251229U, a dust removal device for protective film production is proposed. The utility model utilizes two sets of relatively distributed pushing mechanisms to pre-scrape and remove impurities from the protective film passing through, and subsequently adheres the electrostatic tape to the surface of the protective film, so that the surface of the protective film can be more thoroughly dusted, and the use of a tightening mechanism can make the electrostatic tape and the protective film fit more compact, thereby improving the dust removal quality.

[0003] However, the dust removal method used in the prior art is static scraping, which easily causes dust to remain on the surface of the protective film, resulting in reduced cleaning quality. Moreover, after the dust is removed, the dust will fly into the environment and easily be secondary absorbed by the static electricity of the protective film, resulting in incomplete cleaning of the protective film. Therefore, there is a need to improve the prior art. Utility Model Content

[0006] Preferably, the dust collection mechanism includes a dust box, the upper end of the box body is fixedly connected to the dust box, the upper end of the dust box is fixedly connected to the dust cleaner, the right end of the dust box is fixedly connected to a connecting pipe, one end of the connecting pipe located inside the box body is fixedly connected to a dust hood, the left end of the dust box is hinged with a sealing door, the connecting pipe is fixedly connected to the box body, and the dust hood can absorb dust around the film strip.

[0007] Preferably, a handwheel is fixedly connected to the upper end of the threaded rod, and the guide rod is slidably connected to the threaded rack, and the guide rod can guide the movement of the threaded rack.

[0008] Preferably, the cleaning roller is in contact with the film tape, the output shaft of the motor passes through the frame and does not contact the frame, and the rotation direction of the cleaning roller is opposite to the moving direction of the film tape.

[0009] Preferably, a belt is sleeved on the outer side of the pulley 1, and the belt is in contact with the pulley 2, so that the belt can transmit power.

[0010] Preferably, one end of the spring is fixedly connected to the connecting strip, and the other end of the spring is fixedly connected to the threaded rack, and the spring can support the connecting strip through elastic force.

[0011] Preferably, two symmetrically distributed guide rollers are installed inside the box through bearings, and the guide rollers are in contact with the film tape and can guide the film tape.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model adds a frame, a cleaning roller and a spring structure inside the box. During use, the elastic force of the spring can drive the cleaning roller to squeeze the outside of the film belt, and then the motor drives the cleaning roller to rotate in the opposite direction of the moving direction of the film belt, so that the dust on the surface of the film belt can be dynamically cleaned, which can effectively improve the cleaning quality.

[0014] 2. The utility model adds a dust collecting box, a dust collector and a dust hood to the box body. During the process of cleaning the film strip with the cleaning roller, the dust around the cleaning roller can be sucked by the dust hood, thereby effectively preventing dust from flying and preventing the protective film from absorbing dust for the second time.
