Description

Technical Field

[0001] The invention relates to the technical field of furniture processing, in particular to a furniture production plate polishing machine. Background Art

[0002] Refers to the manufacture of various furniture made of wood, metal, plastic, bamboo, rattan and other materials, which has the functions of sitting, lying, leaning, storage, partitioning, etc., and can be used in any place such as residence, hotel, office, school, restaurant, hospital, theater, park, ship, airplane, motor vehicle, etc. The board of assembled furniture must be polished to improve the quality of the furniture.

[0003] The plate polishing machine relies on a conveyor belt to move the plate, and the polishing roller or polishing wheel rotates. The polishing operation is completed as the plate moves, and the dust generated during polishing is removed by a filter bag dust collector. As the polishing roller is used for a long time, it gradually wears and the outer diameter becomes smaller, resulting in a decrease in the polishing effect on the plate. If it is directly replaced, the cost of using the polishing roller will increase. In addition, when the filter bag is used for dust removal, some dust gradually accumulates on the inner wall of the filter bag, resulting in a decrease in the air permeability of the filter bag. Manual cleaning of the filter bag is time-consuming and laborious. Therefore, it is necessary to propose a furniture production plate polishing machine. Summary of the invention

[0025] Working principle: Step 1: The plate is conveyed from left to right by the conveyor 2, the roller 34 rolls on the upper surface of the plate, the lifting plate rises to trigger the travel switch 33, prompting the second motor 358 to drive the polishing roller 359 to rotate, so that the polishing roller 359 polishes the plate. The distance between the polishing roller 359 and the plate remains unchanged, which is suitable for polishing plates of various shapes; Step 2: As the outer diameter of the polishing roller 359 is worn down, in order to ensure the polishing effect of the plate, the first motor 353 drives the lead screw 354 to rotate clockwise, and the tops of the two connecting rods 356 are simultaneously moved outward under the condition that the lead screw 354 and the lead screw nut 355 are threadedly engaged, so that the support seat 357 is lowered, and the distance between the polishing roller 359 and the plate is adjusted to ensure the polishing effect of the plate; Step 3: Under the suction force of the fan 64, negative pressure is formed in the dust box 621. The suction pipe 67 sucks the dust generated during polishing. The dust enters the dust box 621 along the dust collecting pipe 66. The filter bag 6211 filters the dust to prevent the dust from being inhaled into the lungs of the workers and affecting their respiratory health. Step four, when the dust on the inner wall of the filter bag 6211 accumulates excessively and the air permeability decreases, the third motor 625 drives the first rotating shaft 626 to drive the turntable 627 to rotate, and the hollow cylinder 628 is allowed to rotate under the transmission condition of the meshing of the gear 629 and the inner gear ring 624. The filter bag 6211 faces the chain 633 without dead angles, and the fourth motor 631 drives the chain 633 to swing. The chain 633 repeatedly beats the filter bag 6211 to remove the dust accumulated on the inner wall of the filter bag 6211, clean the filter bag 6211, and ensure the dust removal effect when the plate is polished.
