Wood grinding device

Abstract

The invention discloses a wood grinding and polishing 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 inside the grinding platform. The lower grinding mechanism The upper side is provided with an upper grinding mechanism, both sides of the lower grinding mechanism and the upper grinding mechanism are equipped with a clamping transmission mechanism, and the upper grinding mechanism and the lower grinding mechanism are both rotatably connected with a grinding roller knife structure. The advantage lies in: the structure design of the grinding roller knife structure is driven by the inner drive shaft to rotate the outer knife roller cover. Relative rotation, that is, to prevent the motor from burning out in the case of a knife jam; the adjustment shaft core set inside the inner drive shaft can adjust the insertion depth by the jackscrew, and the circular platform-shaped adjustment block set on the adjustment shaft core can tighten the inner clamping piece , the change of the contact position between the adjustment block and the inner clip effectively changes the elastic force of the first spring to press the outer clip.

Description

Technical field [0001] The present invention relates to the field of wood board processing, and specifically, a wooden grinding grinding device is referred to. Background technique [0002] The wooden board is a wood plate made of a complete wood; these plates are rugged, the texture is natural, very widely used; the wooden board is a wood as a raw material, through wood cutting, wood drying, wood glue, wood surface decoration and other mechanical processing methods or chemical Processing, etc. [0003] However, the wood board grinding device in the prior art is prone to the grinding knife at runtime. When the case occurs, it will cause the motor load moment, and if not, it is not discovered, it is very easy to burn the motor, motor Burning will result in large losses. In the prior art wooden grinding device, a grinding knife that can effectively protect the motor can be effectively protected when a knife occurs. [0004] Secondly, in the prior art wooden board grinding, it is us...

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
