Wood board grinding device

Abstract

The invention discloses a wood board grinding device which comprises a grinding platform, a lower grinding mechanism and an upper grinding mechanism are arranged on the grinding platform, the lower grinding mechanism is arranged in the grinding platform, the upper grinding mechanism is arranged on the upper side of the lower grinding mechanism, and clamping conveying mechanisms are arranged on the two sides of the lower grinding mechanism and the two sides of the upper grinding mechanism correspondingly. The upper grinding mechanism and the lower grinding mechanism are each internally and rotationally connected with a grinding roller cutter structure. The wood board grinding device has the advantages that the inner driving shaft drives the outer cutter roller sleeve to rotate according to the structural design of the grinding roller cutter, when the cutter is clamped by a wood board, the outer clamping piece is separated from the clamping groove, so that the inner driving shaft and the outer cutter roller sleeve can generate relative rotation, and a motor is prevented from being burnt out under the cutter clamping condition; the insertion depth of an adjusting shaft core arranged in the inner driving shaft can be adjusted through a jackscrew, a circular-truncated-cone-shaped adjusting block arranged on the adjusting shaft core can abut against the inner clamping piece, and the elastic force, for extruding the outer clamping piece, of a first spring is effectively changed by changing the contact position of the adjusting block and the inner clamping piece.

Description

technical field [0001] The invention relates to the field of wood board processing equipment, in particular to a wood board grinding and polishing device. Background technique [0002] Wooden boards are wooden boards made of complete wood; these boards are durable, natural in texture, and widely used; wood boards are made of wood, through mechanical processing methods such as wood cutting, wood drying, wood gluing, and wood surface decoration. Processing and other methods, its products still maintain the basic characteristics of wood. In the process of processing wood boards, it is necessary to use a grinding device to smooth the surface of the wood boards to ensure the processing accuracy of the wood boards, and it is also conducive to the subsequent processing of the wood boards. [0003] However, the wood grinding device in the prior art is prone to jamming of the grinding knife during operation. When the jamming situation occurs, the load on the motor will increase insta...

AI Technical Summary

Problems solved by technology

[0003] However, the wood grinding device in the prior art is prone to jamming of the grinding knife during operation. When the jamming situation occurs, the load on the motor will increase instantaneously. If it is not found in time, it is very easy to burn the motor. Burning will bring greater losses. In the wood grinding device of the prior art, there is a lack of grinding knives that can effectively protect the motor when the knives are jammed.

[0004] Secondly, in the prior art, when the wood board is ground, it is usually single-sided grinding. After one side is ground, it is reversed, and then the other side is ground. In this way, the processing process is more complicated, and the wood grinding efficiency is low. ; Therefore, it is urgent to study a kind of plank grinding and grinding device to solve the above-mentioned problems
