Automatic guitar polishing device

Abstract

The invention discloses an automatic guitar polishing device. It includes a box body, a first roller is arranged inside the upper end of the box body, horizontal connecting rods are connected to both sides of the first roller, a vertical sliding rod is connected to the middle of the horizontal connecting rod, and a fixed rod is connected to the other end of the vertical sliding rod. The vertical slide bar is connected with a slide block through a chute, the slide block is connected with the fixed bar through a spring, and a third roller is connected to the inner side of the slide block on the two vertical slide bars; a guitar mold is arranged below the horizontal connecting bar, Both sides of the bottom of the guitar mold are provided with a rack, the rack is connected with a gear, and the gear is connected with a second motor; the first, second and third drums are wound with abrasive belts. The invention has the advantages that the abrasive belt is not easy to slip, the installation of the abrasive belt is simple, the accuracy of the length of the abrasive belt is low, the service life of the abrasive belt is long, the degree of automation is high, the manual grinding environment is good, the grinding flatness is high, and the workload is small. Beneficial effect of high sanding work efficiency.

Description

technical field [0001] The invention relates to a polishing device, in particular to an automatic guitar polishing device. Background technique [0002] At present, the grinding device used in guitar production uses two rollers to drive the abrasive belt for grinding. However, after the abrasive belt is used for a period of time, the abrasive belt will become loose, and the pressure between the abrasive belt and the rollers will decrease. There will be slippage and cannot be used normally; due to the length error of the abrasive belt of the grinding device, the distance between the rollers needs to be continuously adjusted during installation. If the distance between the rollers is too short, the abrasive belt is easy to slip, and the distance between the rollers is too long. The abrasive belt is easily damaged, the installation of the abrasive belt is complicated, and the service life is short; in the grinding device of the guitar, the degree of automation is low, the manua...

[0002] At present, the grinding device used in guitar production uses two rollers to drive the abrasive belt for grinding. However, after the abrasive belt is used for a period of time, the abrasive belt will become loose, and the pressure between the abrasive belt and the rollers will decrease. There will be slippage and cannot be used normally; due to the length error of the abrasive belt of the grinding device, the distance between the rollers needs to be continuously adjusted during installation. If the distance between the rollers is too short, the abrasive belt is easy to slip, and the distance between the rollers is too long. The abrasive belt is easily damaged, the installation of the abrasive belt is complicated, and the service life is short; in the guitar grinding device, the degree of automation is low, the manual grinding environment is poor, the grinding flatness is low, the workload is large, and the grinding efficiency is low

[0003] To sum up, in the prior art, the abrasive belt is prone to slipping, the installation of the abrasive belt is difficult, the accuracy of the length of the abrasive belt is high, the service life of the abrasive belt is short, the degree of automation is low, the manual grinding environment is poor, and the grinding flatness is low , the workload is heavy, and the technical problems of grinding work efficiency are low
