Platen machine

Abstract

The invention discloses a platen machine which comprises a gantry frame and a compacting mould. The compacting mould is composed of multiply heating platens (2a), and an elastic connecting element (2b) is arranged between two adjacent heating platens. Each heating platen (2a) is hollow inside. A heat-exchanger tube (2a1) is arranged inside the platen machine, and the heat-exchanger tube (2a1) is connected with a heat transfer oil circulating system. Guide pillars (1a1, 1ab) used for guiding the multiply heating platens (2a) are arranged on the gantry frame. The platen machine also comprises a buffer device (3) which is fixedly connected on the bottom portion of the beam (1c) of the gantry frame, and is connected with the top layer heating platen of the multiply heating platens of the mould. The compacting mould is driven by a hydraulic cylinder (6) on the bottom portion of the compacting mould. A piston rod (6a) of the hydraulic cylinder is connected with the bottom layer heating platen. The platen machine can be used for compacting multiply wood plates each time, and compacting efficiency is high. Due to the fact heat transfer oil is adopted to transfer heat to the wood plates, the wood plates are heated up quickly, heat is distributed evenly, glue cement among the wood plates is enabled to solidify rapidly, compacting quality is high, and compacting speed is fast.

Description

technical field [0001] The invention belongs to the field of wood board production equipment, in particular to a board pressing machine for hot-pressing multi-layer corrugated boards. Background technique [0002] In the process of making wood boards, it is necessary to use a hot press machine to press and shape the multi-layer glued wood chips. The heat on the hot pressing board is transferred to the glue between the layers of wood chips, so that the glue is quickly solidified and a flat and solid wood board is obtained. . Usually the heat press adopts a steam heat source for heating. However, steam heating is slow and the heat distribution is uneven; it takes a long time to transfer the required heat to the glue between the wood layers to make it solidify. At the same time, due to the uneven heat distribution, the glue between the wood layers cannot be guaranteed. The liquid is completely solidified, and the efficiency and production efficiency are lower when pressing th...

Problems solved by technology

However, steam heating is slow and the heat distribution is uneven; it takes a long time to transfer the required heat to the glue between the wood layers to make it solidify, and because of the uneven heat distribution, the glue between the wood layers cannot be guaranteed. The liquid is completely solidified, and the efficiency and production efficiency are lower when pressing the wood board

At the same time, most of the existing hot pressing machines can only press a single piece or a few pieces of wood, and the pressing efficiency is low.
