Description

Technical Field

[0001] The utility model relates to the technical field of plywood processing, in particular to a trimming device for plywood production. Background Art

[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them together with adhesive. It is usually made with an odd number of veneers, and the fibers of adjacent layers of veneers are glued perpendicular to each other. Plywood needs to be trimmed to ensure consistent size.

[0003] In the prior art, Chinese patent publication number CN108687889A discloses a horizontal edge trimming and stacking device for a plywood trimming machine, comprising a horizontal edge trimming device and a stacking device. When the plywood enters between the pressing strip and the table, the lifting platform descends, allowing the plywood to smoothly enter between the pressing strip and the lifting platform. After most of the plywood enters between the pressing strip and the lifting platform, the lifting platform rises so that the pressing strip and the lifting platform press the plywood tightly, thereby avoiding scratching the sharp corners of the vertical edges of the plywood that has just been trimmed, thereby ensuring the quality of the plywood. After the plywood is trimmed, it is first pushed onto a movable support plate, and then the movable support plate moves to the right. The template is blocked by a blanking baffle from falling on the stacking lifting platform. There is no relative movement between the pushed plywood and the plywood below it, thereby ensuring the surface quality of the plywood and the neat stacking of the boards.

[0004] However, when the utility model is actually used, when the plywood is trimmed, a certain amount of wood chips and broken edges will be generated, which makes it inconvenient to collect and recycle the generated waste. As a result, the cut wood chips are prone to accumulation, affecting the working environment. At the same time, the wood chips are prone to dust and can be easily inhaled into the mouth and nose, so improvement is needed. Utility Model Content
