The amount of solder raw materials that can be processed at a time is greatly increased, the production efficiency of solder melting is significantly improved, the number of batch processing is reduced, the energy consumption and time cost of unit output are reduced, and the demand of large-scale industrial production for solder melting efficiency and capacity is effectively met.

This invention discloses a multi-station three-dimensional shaft pulling device and its usage method for a high-speed film production line. The shaft pulling device includes a shaft pulling mechanism, a transverse movement mechanism, and an upper shaft mechanism connected sequentially along the conveying direction of the air-expanding shaft. The shaft pulling mechanism has a shaft pulling station, and the upper shaft mechanism has an upper shaft station. The shaft pulling mechanism and the upper shaft mechanism are respectively located on opposite sides of the transverse movement mechanism. In the transverse movement mechanism, the first transverse movement movable frame moves horizontally relative to the transverse movement fixed frame, and its extreme positions are the shaft pulling station and the upper shaft station. The second transverse movement movable frame moves horizontally relative to the first transverse movement movable frame, and its extreme positions are the opposite sides of the first transverse movement movable frame. The usage method is to place the multi-station three-dimensional shaft pulling device near the winding mechanism of the high-speed film production line. The air-expanding shaft is pulled out by the shaft pulling mechanism. The first and second transverse movement movable frames in the transverse movement mechanism move horizontally. After receiving the air-expanding shaft at the shaft pulling station, it is sent to the upper shaft station.
