According tothe adopted technical scheme, the novel guitar bag production device and the preparation method thereof have the advantages that the structure is simple, the design is reasonable, the quality of a finished product is good, a guitar can be effectively protected from collision damage and fall damage, the novel appearance is kept for a long time, the guitar is not prone to cracking, and the servicelife of the guitar is greatly prolonged.

Description

technical field [0001] The invention relates to the field of mold machinery, in particular to a novel guitar cover production device and a preparation method thereof. Background technique [0002] The guitar is a musical instrument, which belongs to the plucked string instrument, usually has six strings, and is similar in shape to a violin. The guitar is often regarded as the main instrument in pop music, rock music, blues, folk songs, and flamenco. In the field of classical music, the guitar is often performed as a solo or duet; of course, in chamber music and orchestral music, the guitar also plays a considerable role as a foil. [0003] In order to protect the guitar or carry the guitar conveniently, a special guitar bag is usually used to pack the guitar, and most of the existing guitar bags are dedicated to protecting the integrity of the appearance of the guitar. However, the guitar has a certain weight and volume, and it may fall when playing or taking it, causing d...

AI Technical Summary

Problems solved by technology

However, the guitar has a certain weight and volume, and it may fall when playing or taking it, causing damage to the internal components of the guitar, which will affect the sound quality and appearance of the guitar, and greatly shorten the service life of the guitar

In the past, the price of a guitar was about three to five hundred. People used a guitar to replace it if it broke down. Now, with the continuous improvement of living standards and people's love for art, the price of a random guitar can reach thousands or even tens of thousands. Therefore, there is an urgent need for a product that can effectively protect the guitar, but there is no such product on the market
