Plate hot-pressing device capable of uniformly heating and easily controlling temperature of plate

Abstract

The invention relates to the technical field of plate hot pressing, and discloses a plate hot pressing device capable of uniformly heating and easily controlling temperature of a plate. The plate hotpressing device comprises hot pressing blocks, wherein the tops of the hot pressing blocks are fixedly connected with a pressing rod, the top of each hot pressing block is fixedly connected with an air pressure box, and the bottom of each sliding rod is fixedly connected with a tension spring; and a scraping block is fixedly connected to the bottom of each tension spring, a baffle is movably connected to the interior of each scraping block, a drainage pipe is inserted into the outer side of each hot pressing block, a swing door is movably connected to the inner wall of each drainage pipe, anda reset spring is fixedly connected to the side, away from each scraping block, of each swing door. According to the plate hot-pressing device capable of uniformly heating and easily controlling the temperature of the plate, air is introduced into the air pressure boxes, the air pushes piston rods to move, the piston rods drive pull rods to move, the pull rods drives driving wheels to rotate, thedriving wheels drive transmission wheels to rotate, and the transmission wheels drives gears to rotate, and through the cooperative use of the gears and gear grooves, so that the effect of uniformly heating the interior of the hot pressing plate is achieved.

Description

technical field [0001] The invention relates to the technical field of sheet material hot pressing, in particular to a sheet material hot pressing device with uniform heating and easy temperature control. Background technique [0002] Hot pressing is the process of heating and pressing the paved slab to make a fiber board with certain mechanical strength and water resistance, whether it is wet production of hard board or semi-rigid board, or dry production of hard board. Board or medium density board must be hot pressed to become a board. [0003] When the existing board hot-pressing device is heated by steam, the heating speed of each part inside the hot-pressing plate will be different, causing hot-pressing deformation. At the same time, steam heating will generate condensed water, and the condensed water will not be discharged in time, which will affect the temperature control. , more likely to cause hot pressing deformation.

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a board heat-pressing device that is heated evenly and can control the temperature easily. It has the advantages of uniform temperature rise inside the heat-pressed plate, timely discharge of condensed water, energy saving, and good heat-pressing effect. It solves the problem that the heating speed of each part inside the hot pressing plate is different, causing hot pressing deformation, steam heating will produce condensed water, and the condensed water will not be discharged in time, which will affect the temperature control.
