Technical Field

[0001] This utility model relates to a dustproof conveying device, specifically a dustproof conveying device for the production of shielding film, belonging to the field of shielding film production and processing technology. Background Technology

[0002] Masking film, belonging to the masking product series, is mainly used for masking paint and coatings during the painting of automobiles, ships, trains, cabs, furniture and other products, as well as for interior decoration. The products are divided into two types: high temperature resistant and normal temperature resistant (depending on the different baking temperature environment after the paint is applied in the product manufacturing process).

[0003] Chinese Patent Publication No. CN208664198U discloses a dust removal device for film production, including a dust removal box. The dust removal box is equipped with several guide rollers. The dust removal box is provided with an inlet and an outlet on both sides. A dust removal roller is provided at the inlet. A dust suction device is provided under the dust removal roller. The dust suction device includes a first dust suction port and several second dust suction ports provided on one side of the first dust suction port. The first dust suction port and the second dust suction ports are connected to a dust collection tank through pipes.

[0004] However, the inventor of the above device believes that there are certain defects. The fixed dust removal roller of the above device cannot achieve dynamic cleaning, and the removal effect on firmly attached dust particles is not good. In addition, the single dust suction port design results in insufficient dust removal coverage area and easy to create cleaning dead corners. Therefore, this utility model provides a dustproof conveying device for the production of shielding film. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this utility model is to provide a dustproof conveying device for the production of masking film in order to solve the above-mentioned problems. This device addresses the issues that existing fixed dust removal rollers cannot achieve dynamic cleaning, have poor removal effect on firmly attached dust particles, and have insufficient dust removal coverage area due to the single dust suction port design, which easily leads to cleaning dead corners.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: a dustproof conveying device for the production of masking film, comprising a conveying box, wherein the conveying box is provided with a guiding mechanism, a cleaning mechanism and a conveying mechanism from left to right. The guiding mechanism includes two guide rollers rotating inside the conveying box. The cleaning mechanism includes a sliding frame slidably connected inside the conveying box. The sliding frame has two opposing sliding plates slidably connected inside. Brush rods are detachably connected to the sides of the two sliding plates that are close to each other. Dust collection hoods are fixedly connected to the top and bottom of the sliding frame. Dust collection hoses are fixedly connected to the dust collection hoods. The conveying box is provided with a connecting mechanism that drives the sliding frame to slide back and forth. The conveying mechanism includes two conveying rollers rotating inside the conveying box.

A sliding rod is fixedly connected to the bottom of the installation frame 31. The sliding rod is slidably connected to the bottom of the conveying box 1.

[0024] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5The conveyor box 1 is equipped with a connecting mechanism that drives the sliding frame 4 to slide back and forth. The connecting mechanism includes a rotating gear 9 rotatably connected to the inner wall of the conveyor box 1. A connecting rod 91 is rotatably connected to the rotating gear 9. The other end of the connecting rod 91 is hinged to the side slider 41 by a pin. A first gear 81 is fixedly connected to the rotating shaft of the conveyor roller 8. The first gear 81 meshes with the rotating gear 9. When the conveyor roller 8 rotates, the meshing action of the first gear 81 and the rotating gear 9 drives the rotating gear 9 to rotate. Under the connecting action of the connecting rod 91, the side slider 41 is pulled to slide back and forth. One end of the connecting rod 91 located on the side of the rotating gear 9 is a certain distance away from the center of the rotating gear 9.

[0025] Example 3: Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 One end of the sliding plate 6 is L-shaped, and one end of the sliding plate 6 is connected to the sliding frame 4 by a spring 61. The other end of the sliding plate 6 is fixedly connected to a pressing rod 62. The inner side wall of the conveying box 1 is fixedly connected to a pressing protrusion 63 that presses the pressing rod 62. When the sliding frame 4 slides back and forth, the pressing protrusion 63 indirectly presses the pressing rod 62 to push the sliding plate 6 to slide. Then, the springback of the pressing rod 62 drives the sliding plate 6 to slide back and forth, so that the sliding plate 6 slides back and forth during the left and right sliding process.

[0026] Working principle: The device is installed in a suitable position, with one end of the suction hose 51 connected to an external vacuum cleaner. The mounting frame 31 is raised and lowered by activating the electric push rod 32 to adjust the tension of the film between the two guide rollers 2. The motor on the conveyor box 1 drives one conveyor roller 8 to rotate. The meshing of the two second gears 82 drives both conveyor rollers 8 to rotate together, conveying the film. The meshing of the first gear 81 and the rotating gear 9 drives the rotating gear 9 to rotate. The connecting rod 91 connects the two rollers. The sliding frame 4 is pulled down and slides back and forth inside the conveyor box 1. During the back and forth sliding, the sliding frame 4 indirectly squeezes the squeezing rod 62 by squeezing the squeezing protrusion 63, which pushes the sliding plate 6 away from the squeezing protrusion 63. Then, the springback of the squeezing rod 62 drives the sliding plate 6 to slide back to its original position. During the back and forth sliding, the sliding plate 6 slides back and forth. The two brush rods 7 clean both sides of the membrane. By starting the vacuum equipment, the dust and impurities cleaned are absorbed by the cooperation of the vacuum hood 5 and the vacuum hose 51 to prevent dust from scattering.
