Tube Fitting Machine Product Description:
This machine is specifically designed for joining motorcycle, bicycle, and inner tube billets. It is ideal for use with natural rubber and is suitable for production in Ding Ji. The equipment is considered one of the most efficient solutions for such applications.
The machine features a pneumatic control system, with PLC-controlled valves for precise operation. It uses a linear guide rod mechanism for smooth mechanical transmission, ensuring stability, high precision, and consistent performance. The mold structure is made of rubber, providing strong joint strength and reliable docking pressure. An adjustable electric knife allows for optimal cutting quality, and the machine can handle 1 to 3 tubes simultaneously, significantly boosting productivity.
The design includes a main body, left and right clamping arms, a cutting mechanism, and a docking system. The movement is controlled by a cylinder, and motor speed can be adjusted as needed. The machine requires two hands to press and hold two buttons to start, ensuring safety. If either button is pressed during operation, it triggers an emergency stop, and pressing the reset button returns the machine to its original position, ready for continued use.
