Guitar case polishing equipment with high safety

Abstract

The invention discloses guitar case polishing equipment with high safety. The guitar case polishing equipment comprises a polishing belt support. A driving roller, a first driven roller and a second driven roller are arranged on one side of the polishing belt support. The driving roller is located at the vertex of an equilateral triangle, and the axis position of the driving roller is connected with a transmission shaft. The transmission shaft is connected with a driving mechanism. An equilateral triangle polishing belt is wound outside the driving roller, the first driven roller and the second driven roller. The axis position of the second driven roller is connected with a connecting rod. A bulb is arranged at one end of the connecting rod, and the connecting rod is further connected to aball socket through the bulb. The ball socket is fixed to the polishing belt support. A screw rod perpendicular to the connecting rod is arranged on one side of the connecting rod. An adjusting holeis formed in the side, opposite to the screw rod, of the polishing belt support. The screw rod penetrates through the adjusting hole and then is connected with an adjusting nut. The guitar case polishing equipment with high safety has the characteristics that the polishing belt cannot be abraded easily, replacement is facilitated and using is made safe.

Description

technical field [0001] The invention relates to a polishing device, in particular to a high-safety guitar box polishing equipment. Background technique [0002] Guitar case is a box structure composed of guitar top, back and side panels, which is a very important part of acoustic guitar pronunciation. [0003] In the guitar production process, the guitar top, back panel and side panels need to be made separately and then spliced ​​to form a complete piano box. After the piano box blank is made, follow-up grinding, polishing, painting, etc. are required. craft. Polishing is to use a polishing abrasive belt to continuously rub the surface of the piano box until the surface is fine and smooth. [0004] The current guitar case polishing methods are mainly manual polishing and mechanical polishing. Manual polishing is to use the worker to hold the polishing abrasive belt to continuously wipe the surface of the piano case to complete the polishing. This method requires workers t...

AI Technical Summary

Problems solved by technology

[0004] The current guitar case polishing methods are mainly manual polishing and mechanical polishing. Manual polishing is to use the worker to hold the polishing abrasive belt to continuously wipe the surface of the piano case to complete the polishing. This method requires workers to constantly rub back and forth. The labor intensity is particularly high, very laborious, and the manual polishing is inefficient and time-consuming. For this reason, the mechanical polishing method has gradually replaced the manual polishing device. Mechanical polishing mainly drives the polishing belt to rotate through two rotating rollers. However, since the diameter of the roller is usually set to be small, the distance between the circular polishing belts is narrow, and if the force is too large during polishing, the polishing belts will easily contact each other and cause friction , damage the polishing abrasive belt, and if the polishing abrasive belt is stretched too tightly, the polishing abrasive belt is difficult to disassemble and replace, and, in order to facilitate the replacement of the polishing abrasive belt, the roller usually adopts a roller with a smooth surface. There is a danger of the belt falling off, and there is a certain safety hazard
