Description

Technical Field

[0001] This utility model relates to the field of cardboard printing technology, specifically to a dust collection device for printing. Background Technology

[0002] Packaging printing is printing on various packaging materials to add decorative patterns, designs, or text, making products more attractive or informative, thereby conveying information and increasing sales. It includes printing on cartons, bottles, cans, etc. Packaging printing accounts for a large proportion of both the printing and packaging industries and is an indispensable part of packaging engineering. Printing methods include letterpress printing, offset printing, gravure printing, screen printing, and stencil printing. The main elements of printing include paper, ink, and color. Packaging printing must consider economic efficiency and environmental protection, while simultaneously conveying the information to be printed completely and effectively.

[0003] During the production or stacking process, cardboard accumulates a lot of static charge due to friction. When the cardboard is placed on the printing press, although this static charge is not fatal to humans, it will attract dust, packaging materials, fibers from clothing, hair, microorganisms, residual ink particles, etc. from the surrounding environment to the surface of the printing plate, causing difficulties in the production processes such as printing, lamination, and varnishing. Therefore, dust removal devices for the printing plate are needed.

[0004] Existing printing dust removal devices have a frame with multiple conveyor rollers forming a conveyor platform through which cardboard is transported. The device also includes a dust collector with a suction pipe that opens onto the conveyor platform. However, there are no other features at the suction pipe opening, and dust adheres to the paper via electrostatic attraction. Relying solely on the airflow from the suction pipe is insufficient to completely remove the dust from the paper, resulting in poor dust removal efficiency. Therefore, we propose a printing dust removal device to address these issues. Utility Model Content

[0026] In this embodiment, specifically: the limiting plate 17 cooperates with the dust collection box 13 to achieve movable installation, and a handle 19 is fixedly connected to the limiting plate 17.

[0027] In operation, the following steps are taken: The printed cardboard is placed on the conveyor roller 2 within the conveyor frame 1. Adjusting the knob 12 causes the round tube 8 to rotate, which in turn causes the screw 9 to rotate outwards. The screw 9 then causes the adjusting plate 7 to slide downwards within the mounting sleeve 4. This allows adjustment of the height of the brush bristles 5 and their contact area with the cardboard based on its thickness. The vacuum cleaner 14 and the vibration motor 6 operate, and the vibration generated by the motor 6 increases the cleaning power of the brush bristles 5, effectively removing printing dust.
