Description

Technical Field

[0001] The invention relates to the technical field of automatic winding equipment, in particular to an unfolding winding machine. Background Art

[0002] The traditional unfolding winding machine sets the winding nozzle at the front end of the main shaft, and passes the enameled wire through the inside of the main shaft. Such a structure is only suitable for enameled wire with a thin wire diameter and has a narrow range of use. In order to expand the scope of application of the winding machine, the enameled wire is set outside the main shaft and passes through the fixed part and the sliding part of the winding part respectively. However, the winding part of the unfolding winding machine is currently driven by only one motor, and a spline connection is used between the fixed part and the sliding part. The spline matching makes it difficult to ensure the assembly accuracy of the winding machine, and it can only rotate at a low speed. In addition, the relative shaking amplitude of the mechanism is large during the rotation process, which causes damage to the machine and generates a lot of noise. At the same time, the two parts are driven to rotate by one motor, which makes the motor load large, and cannot drive the winding mechanism to operate at a high speed, and cannot improve production efficiency.
