Plywood hot press

Abstract

The invention discloses a plywood hot press. The plywood hot press comprises a base, two symmetrically arranged first brackets, a cross beam, a hot-press device, an oil way device and an air-drying device. The first brackets are welded at the top of the base. The cross beam is welded between the two first brackets. The hot-press device is connected with the cross beam. The oil way device is connected with the hot-press device and the air-drying device. The air-drying device is arranged at the top of the base. The air-drying device is positioned at the left front side of the hot-press device. The plywood hot press is capable of, through using conduction oil as a heating source, enabling the heating effect to be more excellent compared with the heating effect of steam heating, improving hot-press efficiency, saving energy sources, and through a design of the air-drying device, adequately using hot air generated by waste heat of the conduction oil to perform dehumidification operation ona plywood, improving the hot-press effect of the plywood, and further saving the energy sources.

Description

technical field [0001] The invention relates to the technical field of plywood processing, in particular to a plywood hot press. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. In the production of plywood, the hot press machine is one of the main equipment in the production process of plywood, and it is the equipment used for hot pressing and gluing the slabs after gluing and combination. Most of the current hot presses are heated by steam, but the effect of steam heating is not ideal enough, which affects the efficiency of hot press processing and consumes a lot of energy. [0003] After the hot press completes the hot pressing of the plywood, the plywood needs to be removed ...

Problems solved by technology

[0005] The Chinese patent application number is CN201510392985.1, which discloses an environmentally friendly and energy-saving heating system for a hot press, including a hot press and a heating device. The hot press includes an upper pallet, a lower pallet, a hot press frame and an upper The heating plate between the supporting plate and the lower supporting plate, the two ends of the heating plate are provided with the heat transfer oil inlet and outlet, the heat transfer oil inlet and outlet are connected with the heat transfer oil distribution pipes fixed on both sides of the heat press frame, and the heat transfer oil is supplied by the heating device. The outlet enters the heat transfer oil distribution pipe, passes through the multi-layer heating plate, and then enters the heat transfer oil distribution pipe at the other end. Driven by the circulating pump, it returns to the heating device from the heat transfer oil inlet; the heating device is composed of a heating box and a telescopic bag connected up and down. Although the invention improves the work efficiency, the heat returned from the oil is not fully utilized
