Pneumatic glue injecting pen for guitar machining

Abstract

The invention discloses a pneumatic glue injecting pen for guitar machining. The pneumatic glue injecting pen for guitar machining comprises a pen body and a glue injecting needle; the pen body comprises an air compression section, a glue storage section and a switch section connected in sequence; the glue injecting needle is connected with the switch section; the air compression section comprisesa compression bin; an inflation port is formed in the upper end of the compression bin; an air pressure piston is arranged in the compression bin; the air pressure piston consists of an upper end piston head, a connecting rod and a lower end piston head; a funnel pipe is arranged in the glue storage section; the funnel pipe corresponds to the lower end piston head of the air pressure piston in size; the lower end of the glue storage section is connected with the switch section through the connecting pipe; and a glue injecting switch is arranged on the switch section. The pneumatic glue injecting pen for guitar machining is simple in structure, convenient to hold by a hand, convenient to use, easy to control the gluing quantity, uniform in gluing and accurate in gluing position, and improves the guitar gluing quality.

Description

technical field [0001] The invention relates to a guitar production equipment, in particular to a pneumatic glue injection pen used for guitar processing. Background technique [0002] Guitar (Italian: Chitarra), also translated as guitar or violin. A plucked plucked instrument, usually with six strings, 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. Classical guitar, violin and piano are listed as the world's three most famous musical instruments.

Problems solved by technology

[0003] In the process of guitar making, the step of gluing is indispensable, such as: gluing the side and back of the guitar, gluing the guitar sound beam, gluing the guitar panel guard, etc., all need to be glued. At present, brushing is usually used when gluing guitars. Glue or direct glue extrusion, but the inventor found in the manufacturing process that the way of brushing the glue is more uniform, but the way of brushing the glue is less glue, which will easily lead to unstable bonding, degumming, and glue opening; Squeeze glue, although the amount of glue is large, the amount of glue squeezed is not easy to control, and the glue is unevenly applied; in order to solve the above inventors in the guitar manufacturing process, the inventor selected a syringe for glue application, but due to the high viscosity of the glue, the hand-held syringe It is difficult to push the piston when gluing, and it is easy to shake when applying force, resulting in inaccurate gluing position

Therefore, in the guitar gluing step, there are problems such as difficult to control the amount of glue applied, uneven glue application, and inaccurate glue application positions, and the quality of the guitar is easily affected by the effect of glue application.
