A device for polishing tree ring samples by scraping with a knife and a convex grinding wheel in stages

Abstract

The invention discloses a tree ring sample polishing device which uses a knife and a convex grinding wheel to scrape and grind in stages. Its structure includes: a bidirectional motor, an intelligent grinding device, a fixed seat, a base, and a motor unit. The motor unit is located on the upper end surface of the base. At the same time, it is movably connected with the base, so that the rotation of the gear drives the gear rack below, so that the slider on the tooth groove is forced to mesh with a stable displacement on the slider rack, instead of manual pressure displacement running-in, which can reduce the slipping displacement of the equipment At the same time, through the flatness of the scraping frame at the front end and the arc-shaped structure of the grinding wheel frame, the raised structure can be scraped off in advance during displacement, and the polished wood can be layered in an arc-shaped structure, so that it can be better The work of polishing the wood is faster, and finally, the negative pressure generated by the displacement and compression of the air bag inside the telescopic frame is pulled to attract the wood chips generated by the polishing, so as not to affect the working environment.

Description

technical field [0001] The invention relates to the field of wood polishing treatment, in particular to a tree ring sample polishing device which scrapes and grinds in stages with a cutter and a convex grinding wheel. Background technique [0002] In the current wood polishing device, the staff usually manually presses the air pressure grinding wheel, drives the grinding wheel to rotate with air pressure, and polishes the wood through high-speed rotation, but in this way, it is easy to cause: [0003] When performing polishing work, it is difficult to make the surface of the wood smooth by manual pressing on the raised and rough position of the wood surface by manual pressing, and it cannot be done in a layered manner when it is raised Running-in leads to the need to increase the pressure of the staff to quickly run-in, thereby increasing the working intensity of the staff. At the same time, the manual pressing and air pressure driving methods are easy to cause the abrasive ...

[0002] In the current wood polishing device, the staff usually manually presses the air pressure grinding wheel, drives the grinding wheel to rotate with air pressure, and polishes the wood through high-speed rotation, but in this way, it is easy to cause:

[0003] When performing polishing work, it is difficult to make the surface of the wood smooth by manual pressing on the raised and rough position of the wood surface by manual pressing, and it cannot be done in a layered manner when it is raised Running-in leads to the need to increase the pressure of the staff to quickly run-in, thereby increasing the working intensity of the staff. At the same time, the manual pressing and air pressure driving methods are easy to cause the abrasive tool to slip due to the downward pressure when working, making the work The personal safety of personnel is threatened, and it is difficult to concentrate the output of wood chips that are finally ground by a single grinding wheel, thus affecting the working environment
