Automatic tool sharpener for plank processing

Abstract

The invention belongs to the technical field of tool sharpening machines, and discloses an automatic tool sharpening machine for wood board processing tools, which comprises a workbench, an angle adjusting mechanism, a ball screw, a motor and a tool sharpening disc, a fixed table is rotatably mounted in the workbench, a grinding mechanism is arranged at the top of the workbench through a linear motor, a mounting groove is formed in the top of the fixed table, and the angle adjusting mechanism is arranged in the mounting groove. And liquid storage grooves are formed in the front side and the rear side of the inner wall of the mounting groove correspondingly, the middle of the inner wall of each liquid storage groove is sleeved with a force storage mechanism in a sealed mode, and the top of the inner wall of each liquid storage groove is sleeved with an upper sealing column and a first spring in a sealed mode. The fixing plate is driven to move towards the front side and the rear side of the tool and press the tool in a contact mode, then the first magnetic suction plate is magnetically sucked downwards by the second magnetic suction plate in the downward moving process, the pressure of the upper sealing column and the fixing plate on the tool is increased, and therefore the rapid installation function of the tool is completed, and automatic vertical positioning of the tool can be achieved.

Description

technical field [0001] The invention belongs to the technical field of knife sharpening machines, in particular to an automatic knife sharpening machine for wood board processing. Background technique [0002] Wooden board is a commonly used raw material in the home furnishing field. Well-made wood boards can be obtained by cutting specified wood and other finishing processes, so as to provide raw materials for household products. At present, there are many forms of knives for wood board processing, including A disc-shaped tool for direct cutting of wood boards, and a long strip-shaped tool is mainly used for rotary cutting of wood boards during processing. This type of tool has the advantages of fast rotation and sharp cutting, and this type of tool naturally needs automatic grinding. Knife machine for grinding and maintenance. [0003] Existing automatic sharpening machines usually fix the knives on an internal angle-adjustable fixed platform, and workers use bolts to fix...

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
