Continuous multi-layer dryer for plywood and method using same

Abstract

The invention discloses a continuous multi-layer dryer for plywood and a method using the same. The continuous multi-layer dryer for the plywood comprises a dryer body in which a plurality of layers of horizontal moving conveying belts are arranged; the two ends of the layers of horizontal moving conveying belts are each provided with a lifting conveying mechanism and a clamping conveying mechanism; and the clamping conveying mechanisms are correspondingly arranged on the upper layers of the lifting conveying mechanisms. The method for using the dryer includes the steps that boards are liftedto the upper layer through the lifting conveying mechanisms, the boards are clamped and conveyed into the dryer through the clamping conveying mechanisms to continue to be dried, the above action is repeated ceaselessly, and three-dimensional reciprocating and circulating drying of the boards in the dryer is achieved. By means of continuous multi-layer dryer for the plywood, the boards can reach the optimum drying effect, meanwhile, the space utilizing rate is increased to an extremely large limit, space is saved, the energy consumption is low, and the automatic production degree and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of plate drying equipment, in particular to a plywood continuous multi-layer dryer. Background technique [0002] The production of plywood or plywood is to cut the wood raw material into boards and then go through multiple processes, and the multi-layer boards are glued and laminated to form. Among them, after the board has undergone multiple processes such as scraping putty ash on the surface of the board to fill the gaps, the board will become very wet, and the wet board needs to be dried to release the internal moisture in time before subsequent processing can be carried out. However, the traditional board The drying method is to use spacers to separate the wet plates separately, and then stack them together and pull them into the drying room before drying. After drying, the plates and spacers need to be separated, which is not only cumbersome, time-consuming and laborious. Moreover, the drying efficien...

Among them, after the board has undergone multiple processes such as scraping putty ash on the surface of the board to fill the gaps, the board will become very wet, and the wet board needs to be dried to release the internal moisture in time before subsequent processing can be carried out. However, the traditional board The drying method is to use spacers to separate the wet plates separately, and then stack them together and pull them into the drying room before drying. After drying, the plates and spacers need to be separated, which is not only cumbersome, time-consuming and laborious. Moreover, the drying efficiency is low and the floor area is large

[0003] At present, there are still some plywood dryers on the market. These dryers are basically single-layer or double-layer roller dryers or mesh belt dryers. The hot air blower can only be used, the heat loss is fast, the energy consumption is high, the overall equipment is expensive and the number of drying plates is effective, which greatly reduces the production efficiency and cannot meet the current growing production demand
