Wood grinding device

Abstract

The invention belongs to the technical field of wood processing and particularly discloses a wood grinding device. The wood grinding device comprises a power unit, a grinding unit and a storing unit.The grinding unit comprises an upper grinding roll and a lower grinding roll. The storing unit comprises a storing box and a storing pipe, and the storing pipe is located above the storing box. A falling opening is formed in the upper surface of the storing box, and the upper surface of the other side of the storing box is slidably connected with a sliding plate which is located below the storingpipe. A first spring is connected between the sliding plate and the storing box, and a pushing plate is hinged to the end, close to the grinding unit, of the sliding plate. A second spring is connected between the pushing plate and the sliding plate, and the elastic coefficient of the second spring is larger than that of the first spring. The power unit comprises a communicating pipe and a hydraulic cylinder, and the communicating pipe is loaded with a transmission medium. A first plunger is slidably connected into one side of the communicating pipe, and a second plunger is slidably connectedinto the other side of the communicating pipe. A piston is slidably connected into the communicating pipe, and a piston rod of the hydraulic cylinder is fixedly connected with the piston. The wood grinding efficiency can be improved by using the wood grinding device.

Description

technical field [0001] The invention belongs to the technical field of wood processing, in particular to a wood grinding device. Background technique [0002] With the advancement of science and technology, the development of new materials, and the deepening of wood processing technology, woodworking machinery has made rapid progress in terms of product specifications, quantities, dynamic and static performance, precision, mechanization, automation, safety, and new technology applications. With the development of modernization, woodworking machinery has entered a new stage in terms of modernization, automation, mechatronics and instrument integration and continuous production. [0003] At present, sanding machines are an indispensable tool in woodworking work. Sanding machines are mainly divided into two types: hand-held and desktop. Using hand-held sanding machines requires a relatively high labor intensity for workers. Large-scale wood processing plants generally use deskt...

AI Technical Summary

Problems solved by technology

Using the existing desktop grinder, if the two symmetrical planes of wood are to be polished, generally the way of clamping or adsorption is adopted, one plane is polished first, and then the other plane is polished, or a single part is corrected and clamped , and then use the push mechanism to send the wood into the gap between the two ends of the double grinding wheel for grinding. The push mechanism can only grind one part in one reciprocating motion, and the return stroke of the push mechanism cannot be effectively used, and the efficiency is low
