A laminate heat pressing device with preheating function

Abstract

The invention discloses a laminate heat pressing device with a preheating function, comprising a workbench, a support column is fixedly installed at the bottom of the workbench, and a vertical plate is fixedly connected to the top of the workbench, the vertical plate A supporting plate is fixedly installed on the top. In the present invention, under the action of the transmission preheating mechanism, the rotating rod rotates inside the fixed bearing, so that the rotating rod drives the guide roller to rotate between the horizontal plates, so that the guide roller can transport the laminate on the surface , by setting multiple sets of heating rods inside the guide roller, under the elastic action of the first return spring, the heating rods are moved toward the outer wall of the guide roller, so that the heating rods are on the surface of the guide roller against the laminated plate The surface is heated and preheated, which is convenient to reduce the temperature difference of the laminate in the subsequent hot pressing, avoiding the distortion, depression, protrusion and other problems of the laminate due to excessive heating or concentrated heating, and improving the production quality of the laminate hot pressing device , reduce the scrap rate.

Description

technical field [0001] The invention relates to the technical field of sheet material processing, in particular to a laminate hot-pressing device with a preheating function. Background technique [0002] Laminate hot press machine is one of the main equipment in the laminate production process. It is used to heat-press and glue the slabs after gluing and combination. Different types of laminates have different requirements for the performance of the press: ordinary The pressure required for the manufacture of laminates, aviation laminates, plastic veneers, wood-laminated plastic panels, and ship laminates increases in turn. The laminate heat press is divided into two types according to the operation mode: periodic and continuous. The domestic commonly used is Periodic multi-layer heat press. [0003] Existing hot-pressing devices for laminates tend to cause changes in the water content of the glue and the board when hot-pressing the laminates, which affects the quality of t...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing hot-pressing device for laminates tends to cause changes in the water content of the glue and the board when hot-pressing the laminates, which affects the quality of the laminates and does not have the ability to transport the laminates. During the process, the guide roller is used to preheat the mechanism, which leads to a large temperature difference of the laminated board during hot pressing, which is easy to cause deformation or bending of the hot-pressed board in the later stage, and does not have the ability to limit and prevent the laminated board from being transported. The supporting mechanism cannot guarantee the safety and stability during the processing of laminates, and has the disadvantages of low work efficiency, so a laminate heat pressing device with preheating function is proposed
