Fiberboard surface shaping and processing device

Abstract

The invention relates to a fiberboard surface shaping and processing device. The fiberboard surface shaping and processing device includes a conveying device, a hot pressing device, a base and a pairof brackets; the conveying device is arranged on the base; the hot pressing device is arranged above the conveying device; and the brackets stretch across the two sides of the conveying device. Through the fiberboard surface shaping and processing device, fiberboards are placed on a belt and conveyed forward at first, when an infrared sensor detects the fiberboard, the fiberboards are stopped at aspecified position, a lower mold rises to jack up the fiberboards at this time, when the lower mold rises to a certain height, an extension plate is driven by a second cylinder to turn over so as tobe on the same plane with the lower mold, thus the fiberboards are located between four limiting blocks, then an upper mold is driven by a first cylinder to move a screw nut on a threaded rod, a firstconnecting rod connected with the threaded rod enables the upper mold to move downwards, and hot pressing of the fiberboards can be completed after hot pressing for a period of time. Through the fiberboard surface shaping and processing device, the problem that hot pressing of fiberboards in the prior art is directly performed on a conveyor belt, resulting in damage to the conveyor belt is solved.

Description

technical field [0001] The invention relates to the field of plate processing equipment, in particular to a fiberboard surface shaping and processing device. Background technique [0002] Fiberboard is a wood-based panel made of wood fiber or other vegetable fiber, with urea-formaldehyde resin or other suitable adhesives; China's fiberboard started in the 1970s, and its advantages include uniform material, small vertical and horizontal strength differences, It is not easy to crack, etc.; fiberboard is classified into non-compressed and compressed according to density; the density of non-compressed products is less than 0.4g / cm 3 , Compressed products are divided into medium density fiberboard and hard fiberboard; usually, the molding process of fiberboard is divided into wet fiberboard, dry fiberboard, and oriented fiberboard; the production process of fiberboard mainly includes fiber separation, slurry treatment, slab forming, thermal Pressing and post-processing; among th...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a fiberboard surface shaping and processing device to solve the problem of the fiberboard hot pressing directly on the conveyor belt in the prior art proposed in the above background technology, resulting in damage to the conveyor belt: the device will The fiberboard is placed on the belt and transported forward. When the infrared sensor detects it, the fiberboard stops at the designated position. At this time, the lower mold rises to lift the fiberboard. When the lower mold rises to a certain height, the extension plate turns over under the drive of the second cylinder. As for the lower die on the same plane, the fiberboard is between the four limit blocks, and then the upper die is driven by the first cylinder to make the screw nut move on the threaded rod, and the first connecting rod connected by the threaded rod makes the upper die The mold moves down, then adjusts the corresponding pressure and the temperature of the upper mold, and heats for a period of time to complete the hot pressing of the fiberboard
