Description

Technical Field

[0001] The invention relates to the technical field of plate dust removal, in particular to a surface and side dust removal device for a particle board and a finished plate thereof. Background Art

[0002] Veneer is a thin sheet material used to decorate and protect the surface of buildings. Its full name is decorative veneer plywood. It is made of natural wood, technical wood or other materials (such as stone, ceramic plate, metal, etc.) sliced ​​into thin sheets of a certain thickness, then adhered to the surface of base boards such as plywood, fiberboard, particleboard, etc., and then subjected to heat pressing to form a board;

[0003] Decorative panels are lightweight, high-strength, easy to process, and have good weather resistance, so they are widely used in architectural decoration and furniture manufacturing. They can not only improve the appearance and texture of buildings, but also protect walls from damage and pollution;

[0004] There are many different materials and processing techniques for veneers, so you can choose according to different decoration needs. For example, solid wood veneers have the texture and touch of natural wood, which is very suitable for decoration that pursues a natural style; while paper veneers such as melamine impregnated film paper veneers have fire and moisture-proof properties, which are particularly suitable for use in kitchens and bathrooms.

[0005] When processing decorative panels, dust removal equipment is needed to remove dust from particle boards and finished boards to ensure the quality of the decorative panels after processing. However, most of the existing dust removal equipment for particle boards and finished boards can only remove dust from two sides of particle boards and finished boards, but cannot remove dust from the sides of particle boards and finished boards, thereby affecting the dust removal effect of plain boards and finished boards. When the dust that is not cleaned up during veneer veneering of particle boards affects the quality of veneer veneering and when the dust on the sides of finished boards falls on the finished boards below during stacking, the mutual squeezing between the finished boards can easily cause damage. For this reason, we propose a surface and side dust removal device for particle boards and their finished boards. Summary of the invention

[0041] Working principle of the present invention:

[0042] First, the dust removal device is installed before the particleboard is cut onto the upper board and after the finished board is discharged. The conveying roller 102 is driven by a motor to rotate to convey the particleboard or the finished board between the upper shell 201 and the lower shell 202. When the particleboard or the finished board is between the upper shell 201 and the lower shell 202 of the particleboard or the finished board conveyor belt 404, one end of the particleboard or the finished board squeezes the first brush roller 505 on the left side to cooperate with the slider 502 to move in the slide groove 501, so that the first brush roller 505 on the left side is placed on the surface of the particleboard or the finished board, and then the particleboard or the finished board continues to move and contacts with the first brush roller 505 on the right side, thereby cooperating with the first spring 50 4, the elastic force of the first brush roller 505 pushes the first brush roller 505 to stably contact with the right end of the particle board or the finished board, and at the same time, the first brush roller 505 on the right side is driven by the motor to rotate at a high speed to remove dust from the right end of the particle board or the finished board. When the particle board or the finished board continues to move, the first brush roller 505 on the left side is separated from the surface of the particle board or the finished board, and the elastic force of the first spring 504 is used to push the first brush roller 505 on the left side to contact with the left end surface of the particle board or the finished board, and at the same time, the first brush roller 505 on the left side is driven by the motor to rotate at a high speed to remove dust from the left end of the particle board or the finished board, and at the same time, the driving roller 402 is driven by the motor to rotate, thereby driving The cleaning brush 403 on the conveyor belt 404 rotates to remove dust from both sides of the particleboard or finished board, and then the first cylinder 301 is started to push the second brush roller 304 and the wiping roller 302 to contact the two sides of the particleboard or finished board, and then the second brush roller 304 and the wiping roller 302 are driven to rotate by the driving motor 305, so that the second brush roller 304 can remove dust from both sides of the particleboard or finished board and wipe it at the same time, so that the surface and side of the conveyed particleboard or finished board can be cleaned and dusted at the same time, thereby improving the dust removal quality of the particleboard or finished board, thereby avoiding the particleboard being not cleaned when veneering. Dust affects the quality of veneer and when the dust on the sides of the finished boards falls onto the finished boards below during stacking, the finished boards are squeezed against each other and damaged. When the surface of the finished boards is dusted, the second brush roller 304 rotates to drive the ball 803 to rotate, so that the detergent adhered to the surface of the ball 803 is coated on the second brush roller 304, and the detergent is applied to the surface of the finished boards through the second brush roller 304, so that the stubborn stains on the surface of the finished boards can be softened and decomposed, and then the softened and decomposed stubborn stains are wiped by the wiping roller 302, so as to further improve the dust cleaning effect on the surface of the finished boards.
