Description

TECHNICAL FIELD

[0001] The utility model relates to conveying device technical field, concretely is a kind of device for reducing single board breakage in conveying process. BACKGROUND

[0002] Ecological wood board is a kind of wood-based panel product, which is composed of solid wood veneer bonded together by resin. The production process mainly includes peeling and cutting raw wood into veneer, then spreading the veneer, making the grain direction of each veneer perpendicular to its adjacent veneer, pressing them together with glue, trimming and polishing into shape, and then laying melamine paper layer on the hot-pressed substrate board to form the ecological board we need.

[0003] At present, veneer is transported by conveying vehicle during conveying. The original design of conveying vehicle is to improve production efficiency, so that the veneer can be quickly and smoothly transferred from one process to another. However, in actual operation, when the conveying vehicle encounters steep slope or uneven road surface, problems often occur. When the operator pushes or pulls the conveying vehicle, if the operator accidentally drops the conveying vehicle or the ground is slippery due to other reasons, the conveying vehicle will continue to move forward due to inertia. In this case, the conveying vehicle is easy to bump, not only causing damage to the conveying vehicle itself, but more importantly, the veneer inside the conveying vehicle will also be damaged due to the violent vibration and impact. Once the veneer is damaged, it will directly affect the subsequent processing flow. UTILITY MODEL CONTENTS
