Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of glue spraying and dust cleaning before box pasting machine, and specifically relates to a glue spraying and dust cleaning device before box pasting machine. BACKGROUND

[0002] The box pasting machine is a device for folding and sticking the paperboard printed and die cut into a shape, and in the processing of the packaging box, the paperboard to be processed needs to be sprayed with glue, so a glue spraying device is needed.

[0003] A glue coating device for a box pasting machine is disclosed in a Chinese patent with the publication number CN221137088U, which is provided with a glue coating assembly on the conveying belt. The glue coating assembly includes a horizontal rod, two movable seats that can move on the horizontal rod, and two screws that limit the movement of the movable seats. The screws pass through the movable seats, and the glue liquid is coated on the paperboard body at the bottom end of the glue outlet pipe. Then, the pusher is started, and the glue outlet pipe moves, so that the glue liquid can be evenly coated on both sides of the paperboard body. By rotating the screw, the limiting block is separated from the horizontal rod, and the movable seat moves along the horizontal rod, so that the position of the two movable seats can be temporarily adjusted, and the position of the two glue outlet pipes can be temporarily adjusted. By starting the first lifter, the horizontal rod can be lifted, which facilitates the temporary adjustment of the height of the two glue outlet pipes and the coating of the paperboard body of different sizes.

[0004] The glue coating device for the box pasting machine lacks an effective dust removal mechanism before coating the paperboard with glue, and dust and impurities are easily attached to the surface of the paperboard. These dust and impurities form a barrier layer, which prevents the glue from fully wetting the surface of the paperboard, thereby affecting the glue spraying effect. Moreover, the dust and impurities on the surface of the paperboard interfere with the uniform spraying of the glue, which cannot be evenly sprayed on the surface of the paperboard, resulting in problems such as glue leakage, glue deficiency, or glue accumulation at the bonding site, thereby reducing the product quality. Therefore, a glue spraying and dust cleaning device before box pasting machine is proposed to solve the above problems. SUMMARY

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised in the background art, the utility model provides a glue spraying and dust cleaning device before box pasting machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A dust removal device before glue spraying for a box-gluing machine, comprising two support plates, with a fixed frame fixedly connected to the two support plates. Two first pneumatic cylinders are installed on the top side of the fixed frame. A first pneumatic rod is fitted to the working end of each first pneumatic cylinder. A dust suction hood is fixedly connected to the bottom end of each of the two first pneumatic rods. Fixed plates are fixedly connected to both sides of the port of the dust suction hood. A cleaning brush is installed between the two fixed plates via a rotating shaft. A first motor is installed on one of the fixed plates, with its output end connected to one end of the rotating shaft. A dust collection box is installed on the top side of the fixed frame. A suction pipe connects the dust collection box to the dust suction hood. A negative pressure pump is installed on the dust collection box. An air extraction pipe is connected to the input port of the negative pressure pump, and the other end of the air extraction pipe is connected to the dust collection box. An exhaust pipe is connected to the output port of the negative pressure pump. This is to ensure the glue coating effect. Before applying adhesive to the cardboard, the surface needs to be cleaned. The first pneumatic cylinder is activated, causing the first pneumatic rod to move the dust suction hood and cleaning brush downwards until the cleaning brush contacts the cardboard surface. At this point, the first pneumatic cylinder stops, and the first electric motor is activated, causing the cleaning brush to rotate. This cleans the dust and impurities adhering to the cardboard surface. Simultaneously, a negative pressure pump is activated, drawing gas from the dust collection box through the extraction pipe and expelling it through the exhaust pipe. This creates a negative pressure environment inside the dust collection box, allowing the cleaned dust and impurities to be quickly drawn in. The coordinated operation of the cleaning brush and dust suction hood significantly improves cleaning efficiency and ensures a clean cardboard surface. A clean cardboard surface facilitates full contact and adhesion between the adhesive and the cardboard, enhancing coating adhesion and ensuring even distribution of the adhesive on the cardboard surface, forming a uniform and continuous coating. This improves the coating effect and product quality.
