Description

Technical Field

[0001] The present invention relates to the technical field of power equipment manufacturing, and particularly relates to a wire winding and unwinding device for a transformer coil. Background Art

[0002] Most of the tooling equipment used by manufacturers in the industry to produce transformers is still in the initial stage. The tooling equipment has a simple structure, mainly relying on manual operation, and lacks automation capabilities. However, with the continuous development of the social economy, the labor cost of enterprises has increased, and the competition in the industry has gradually intensified. Therefore, improving the automation capabilities of the tooling equipment for transformer production has become an inevitable trend in the industry development.

[0003] Currently, the wire unwinding device mainly consists of main components such as a wire reel shaft, a spring, a brake pad, and a wheel. When in use, the wire is installed on the wire reel shaft, one end of the wire reel shaft is connected to the brake pad, and the tension of the wire is controlled by adjusting the tightness of the brake pad. Wheels are installed on the base of the wire unwinding device. When the wire moves horizontally left and right, the wire unwinding device is pushed to move along the ground by relying on the wheels. The above solution has the following disadvantages: First, the wire tension adjustment device of the existing wire unwinding device is simple, and only relies on the friction of the brake pad to control the tension. The tension force cannot be quantified and can only be adjusted based on experience, and the tension output cannot be kept constant. Second, the left and right horizontal movement of the wire of the existing wire unwinding device needs to be manually pushed and moves by relying on the wheels installed on the base of the device. The wire unwinding device is not fixed to the ground, and there is a safety hazard of tipping over when the wire tension is too large. Third, the existing wire unwinding device only has the function of unwinding wire. When winding the wire, two people need to cooperate in the operation. One person operates the winding equipment, and the other person cooperates to manually rotate the wire shaft to complete the winding. Summary of the Invention
