Description

Technical Field

[0001] The utility model belongs to the technical field of laminating machines, in particular to a cardboard laminating machine with a dust removal structure. Background Art

[0002] Cardboard lamination is widely used in the packaging industry. It covers the cardboard surface with a layer of plastic film to improve its waterproofness, wear resistance and aesthetic appearance.

[0003] Publication number CN220904121U discloses a cardboard laminating machine, comprising a laminating mechanism, a conveying platform provided on the side of the laminating mechanism, a cutting knife and a pressing mechanism provided in sequence on the upper portion of the conveying platform, the cutting knife being able to move up and down, and the pressing mechanism comprising a heating platform and a pressing roller, the pressing roller being located on the upper portion of the heating platform. The utility model presses the edges of the cardboard after lamination and cutting through the cooperation of the heating platform and the pressing roller, effectively improving the bonding strength between the edge of the cardboard and the film and preventing the edge of the cardboard from warping. However, during the processing, transportation, and storage of cardboard, dust, fine particles, and fiber residues are easily absorbed on the surface. In the absence of a dust removal device, these dust particles directly enter the laminating process, which not only causes defects such as unevenness, bubbles, or wrinkles on the surface of the cardboard after lamination, but also affects the bonding effect between the laminating material and the cardboard. For this reason, we propose a cardboard laminating machine with a dust removal structure. Utility Model Content

[0004] In order to solve the problems raised in the background technology, the utility model provides the following technical solutions: a cardboard laminating machine with a dust removal structure, comprising a laminating mechanism and a conveyor belt, the laminating mechanism being arranged on the conveyor belt, a dust removal bracket being arranged at one end of the conveyor belt away from the laminating mechanism, a fan being arranged on the dust removal bracket, the fan being connected to a wind nozzle, an extension being arranged on the dust removal bracket, a dust collector being arranged on the extension being connected to a dust collecting bin through a dust suction pipe, the dust collecting bin being arranged on the side of the conveyor belt, an electrostatic adsorption bracket being arranged between the laminating mechanism and the dust removal bracket, an electrostatic adsorption plate being arranged on the electrostatic adsorption bracket, and the electrostatic adsorption plate being connected to a high-voltage power supply through an electrode connecting line.

[0005] Preferably, a telescopic rod is provided under the electrostatic adsorption plate, the fixed end of the telescopic rod is connected to the electrostatic adsorption bracket, and a wiping head is provided on the telescopic rod. The wiping head is slidably connected to the surface of the electrostatic adsorption plate and is used to regularly clean the electrostatic adsorption plate to prevent the electrostatic adsorption plate from affecting the dust removal efficiency due to dust accumulation.

[0006] Preferably, the wind force of the fan is adjustable, and the air nozzle is a flat slit design. The airflow direction of the air nozzle is parallel to the surface of the cardboard, which can evenly cover the surface of the cardboard and make the airflow parallel to the surface of the cardboard to prevent dust from falling back.

[0007] Preferably, the electrostatic adsorption bracket is an insulating bracket to ensure that the electrostatic adsorption plate does not cause electric shock risks to other parts of the machine and operators when working, thereby ensuring equipment safety.

[0008] Preferably, the wiping head is detachable and made of antistatic material, such as polyurethane, silicone or antistatic cloth, to prevent new static electricity from being generated during the wiping process and to avoid dust from adhering again.

[0009] Preferably, the surface of the conveyor belt is coated with a dustproof coating, which is a Teflon coating. Its low friction and anti-adhesion properties can reduce the deposition of dust on the conveyor belt and avoid secondary contamination of the cardboard during the conveying process.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] During operation, the cardboard is transported to the dust removal area by the conveyor belt, and the fan covers the entire surface of the cardboard with air through the air nozzle, blowing up the dust attached to the cardboard. The dust blown by the fan is immediately sucked into the vacuum cleaner and transported to the dust collection bin through the dust suction pipe. After the blowing and vacuuming processes, there may still be some fine dust particles left on the surface of the cardboard. It continues to move forward. The electrostatic adsorption plate is powered by a high-voltage power supply to generate an electrostatic field. The electrostatic field generates electrostatic attraction for tiny charged dust particles, adsorbing these particles to make the cardboard thoroughly clean. After completing the dust removal step, the cardboard continues to move forward through the conveyor belt and enters the laminating mechanism. The cardboard is thoroughly cleaned before entering the laminating area, effectively removing large dust particles and fine particles on the surface, avoiding common problems such as bubbles, wrinkles and poor adhesion of the film layer, and improving the quality of the finished laminated product.
