Description

Technical Field

[0001] This utility model belongs to the field of tube cleaning technology, specifically relating to an electric tube cleaning device. Background Technology

[0002] As an important component of the launching device, the inner wall of the barrel often has projectile residue adhering to it. Due to the high temperature and pressure during launch, the residue adheres very firmly. The traditional method for removing the residue is to add gasoline, soapy water, ammonia, abrasive, and cleaning agent to the brush head, and then manually clean the inner wall of the barrel by pushing and pulling the cleaning strip and cooperating with the brush head and motor.

[0003] To address the time-consuming and labor-intensive nature of gun barrel cleaning, electric and pneumatic gun barrel cleaning systems are becoming increasingly popular, replacing manual gun barrel cleaning. However, when using electric or pneumatic gun barrel cleaning systems, it is impossible to achieve full automation of the cleaning system's movement and cleaning process. Therefore, it is necessary to design an electric gun barrel cleaning device. Utility Model Content
