Description

Technical Field

[0001] The utility model belongs to the field of fishing gear processing equipment, in particular to an inner wall cleaning machine. Background Art

[0002] During the processing of fishing rods, the carbon fiber rod body needs to be cut, polished, and chamfered. During this process, debris will be generated. The debris will stick to the inner wall of the rod body and affect subsequent painting and other processes. The inner wall of the rod body is manually cleaned. The operator uses a wire to push a dust-free cloth dipped in alcohol or other cleaning agents to move in the lumen of the rod body to wipe the inner wall. This method cannot ensure reliable contact between the dust-free cloth and the lumen during the wiping process, and it is easy to miss, and the cleaning effect of the inner wall cannot be guaranteed. At the same time, manual cleaning has low work efficiency and high labor costs. The automatic inner wall cleaning equipment (CN116511188A) developed by the applicant inserts the cleaning bullet into one end of the inner cavity of the rod body to be cleaned, and uses the blowing bullet mechanism to blow the cleaning bullet out of the inner cavity of the rod body. The cleaning bullet completes the cleaning of the inner wall during the movement of the inner cavity of the rod body. The equipment improves the cleaning efficiency and cleaning effect of the inner wall. However, during use, the cleaning bullets need to be inserted into the inner cavity of the rod to be cleaned one by one, which restricts the cleaning efficiency. The blowing mechanism uses a blowing head connected to a high-pressure air supply device. The size of the cleaning bullet is relatively limited due to the force of the gas blown out by the blowing head, which affects the cleaning effect on the inner wall and is difficult to meet application scenarios with high requirements for the cleanliness of the inner wall.
