Automatic knife sharpener for wood processing

Abstract

The invention belongs to the technical field of knife sharpeners, and discloses an automatic knife sharpener for wood board processing, comprising a worktable, an angle adjustment mechanism, a ball screw, a motor and a knife sharpening disc. The top of the worktable is provided with a grinding mechanism through a linear motor, the top of the fixed table is provided with an installation groove, and the front and rear sides of the inner wall of the installation groove are provided with liquid storage tanks. The middle sealing sleeve is connected with a force accumulating mechanism, and the top sealing sleeve of the inner wall of the liquid storage tank is connected with an upper sealing column and a No. 1 spring. The invention drives the fixed plate to move to the front and rear sides of the tool and presses it in contact, and then uses the No. 1 magnetic suction plate to be magnetically attracted downward by the No. 2 magnetic suction plate during the downward movement process, so that the upper sealing column and the fixed plate are placed on the tool. The pressure is increased, so that the quick installation function of the tool is completed, and the automatic vertical positioning of the tool can be realized.

Description

technical field [0001] The invention belongs to the technical field of sharpening machines, in particular to an automatic sharpening machine for cutting tools used for wood board processing. Background technique [0002] Wood board is a commonly used raw material in the field of home furnishing. By cutting specified wood and other finishing processes, well-made boards can be obtained, so as to provide raw materials for household products. At present, there are many forms of knives used for wood board processing, including There is a disc-shaped tool for direct cutting of wood boards, and a long-shaped tool is mainly used for the rotary cutting of wood boards in the process of processing. Knife machine for grinding and maintenance. [0003] The existing automatic sharpener usually fixes the tool on an internal fixed table with an adjustable angle, and the worker uses bolts to fix the surface of the tool. This installation and fixing method is extremely inefficient, and the w...

AI Technical Summary

Problems solved by technology

[0003]The existing automatic knife sharpening machine usually fixes the knife on an internal angle-adjustable fixed platform, and the workers use bolts to fix the surface of the knife. This installation And the fixing method is extremely inefficient, workers need to use a wrench to adjust the tightness one by one, which is easy to cause a slight deviation in the fixing angle of the tool after the installation is completed

[0004]At the same time, in the processing link after installation, the workers will drive the high-speed rotating grinding disc to move down through the lifting mechanism of the screw and make the grinding disc contact with the tool. Then pressure is applied and the grinding is completed by high-speed rotation, but there will be a problem in the process of moving down: as the grinding disc continues to move down, the pressure between it and the tool is increasing, and the tool is grinding during the grinding process. The thickness of the consumable layer of the surface rust is very small, and after the grinding is completed, it is easy to cause excessive pressure between the two, resulting in excessive grinding and even damage to the tool

[0005] In addition, tools with the same length and different thicknesses will produce grinding waste during the grinding process, and these wastes will cause damage to fixing mechanisms such as bolts as the coolant flows down. Corrosion, rust, and will block the rotation channel of the bolt, causing subsequent installation difficulties
