Description

Technical Field

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

[0002] Silicone protective film is a product that is mostly used in electronic devices to protect their screens. The current mainstream silicone protective film is made of PET material and is suitable for protecting the surfaces of mobile phones, computers, and various display screens. The protective film uses advanced technology to allow the protective film to be directly adsorbed on the screen surface using static electricity and will not fall off at will, achieving the effect of all-round protection of the screen. During the processing of the silicone protective film, the silicone protective film needs to be dusted, so a dust removal device is required.

[0003] In order to improve the dust removal effect when the silicone protective film is generated, the prior art has made many improvements to the silicone protective film dust removal device, such as the patent with patent announcement number CN208466598U, which discloses a dust removal device for silicone protective film processing, including a dust removal chamber, a transmission roller, a motor, a lower dust sticking roller, a cylinder, an adjustment plate, an upper dust sticking roller and a silicone protective film, wherein the dust removal chamber is arranged on a bracket, a positioning groove is arranged on the positioning plate, the transmission roller is arranged in the dust removal chamber, the motor is arranged on the outer wall of the dust removal chamber, the lower dust sticking roller is arranged with a connecting shaft at both ends, the cylinder is arranged at the top of the dust removal chamber, the adjustment plate is arranged on the piston rod, and the silicone protective film enters the dust removal chamber from the feed port. The utility model is provided with a spring between the bottom of the positioning groove and the fixing ring, and the elasticity of the fixing ring in the positioning groove is improved by the spring, thereby improving the elasticity of the lower dust sticking roller, avoiding the situation where the silicone protective film has poor dust removal quality due to too fast or too slow transmission speed, and improving the dust removal quality of the back of the silicone protective film.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, a plurality of dust-sticking rollers are provided to remove dust from the silicone protective film. However, in the existing situation, the dust adhesion amount of the dust-sticking roller has a certain range. When the silicone protective film is dusted for a long time, more and more dust will be on the surface of the dust-sticking roller, which will reduce the dust removal effect of the silicone protective film, and the dust-sticking roller needs to be replaced regularly. The replacement of the dust-sticking roller in the above-mentioned comparative document is more troublesome and requires shutdown for replacement, which reduces the efficiency of dust removal of the silicone protective film. Therefore, there is an urgent need in the art to improve the silicone protective film dust removal device to solve the defects of the prior art. Utility Model Content

The sides of the two racks 6 are fixedly installed with mounting rods 16, and the side of each mounting rod 16 is sleeved with a dust-sticking roller 10. The two dust-sticking rollers 10 are respectively located on the upper and lower surfaces of the protective film body 3. One end of the first gear 7 is fixedly connected with an adjusting bolt 8 extending to the outside, and the side of the adjusting bolt 8 is threadedly connected with a limiting nut 9. A driving unit 11 for driving the protective film body 3 to move is provided on the side of the dust removal box 1. A maintenance port 12 is provided on one side of the dust removal box 1, and a maintenance door panel 13 that can be opened and closed is provided in the maintenance port 12. After the maintenance door panel 13 is closed, one side abuts against the end of the mounting rod 16.

[0032] Specific implementation method in this embodiment: when it is necessary to remove dust from the silicone protective film body 3, the protective film body 3 is input into the dust removal box 1 through the driving unit 11, and the adjusting bolt 8 is rotated. The adjusting bolt 8 drives the first gear 7 to rotate. When the first gear 7 rotates, it drives the first rack 5 and the second rack 6 to move toward each other. The first rack 5 and the second rack 6 drive the two dust-sticking rollers 10 to move toward each other and press against the protective film body 3, and several dust-sticking rollers 10 tighten the protective film body 3 in the up and down directions, and tighten the limit nut 9 to limit and fix the adjusting bolt 8. The dust removal unit 4 is a plurality of groups. In this embodiment, three groups of dust removal units 4 are taken as an example. Two groups of dust removal units 4 can be adjusted first, and one dust removal unit 4 can be left for standby.
