Medium-density fiberboard sawing method and sawing device

Abstract

The invention discloses a medium-density fiberboard sawing method and a sawing device. The sawing device comprises a driving pulley, an electromotor which is connected with the driving pulley and drives the driving pulley to rotate and a conveying belt for connecting the driving pulley to a driven pulley and driving the driven pulley to rotate through the driving pulley, wherein the driven pulley is connected with a transmission shaft through key connection; the transmission shaft is connected with a plurality of sawing mechanisms through key connection; the bottoms of the sawing mechanisms are connected with a scissor mechanism through threads; a first cylinder is connected with the transmission shaft through a guide rod and drives the transmission shaft through the guide rod so as to realize longitudinal movement; and a second cylinder is connected with the scissor mechanism through a guide rod and drives the scissor mechanism through the guide rod so as to realize transverse movement. The separation of the electromotor from the sawing mechanisms is realized, the energy consumption of the sawing device is reduced, and the sawing precision of the sawing mechanisms is also greatly improved; and at the same time, the problem that the sawing device stops for manually adjusting the clearances of sawing blades when different dimensions of plates are cut is thoroughly solved, and the production efficiency of the sawing device is greatly increased.

Description

technical field

[0001] The invention belongs to the technical field of medium fiber board cutting, and in particular relates to a medium fiber board sawing method and a sawing device. Background technique

[0002] MDF is a kind of density board, including long fiberboard and short fiberboard. It is a kind of man-made board made of wood fiber or other plant fiber as raw material, after crushing, fiber separation, drying, applying urea-formaldehyde resin or other suitable adhesives, and then hot pressing. Its density is generally 0.5-0.8 g / cm 3 Range, the thickness is generally 3-30 mm. Because the surface of medium density fiberboard is flat and smooth, it can not only glue planed veneer and tissue paper and other decorative materials, but also facilitate painting and save paint, and can be produced from 3mm-30mm, which can replace wood boards and square materials of any thickness. , and has good machining performance, sawing, drilling, grooving, tenoning, sanding and engr...
