Technical Field

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are coils and an iron core. Horizontal and vertical winding machines are primarily used for winding transformer coils. Horizontal winding machines require a winding machine and a pay-off stand to complete the winding process. However, using existing technology to produce low-voltage AC coils with 6-8 helices is very inconvenient. The winding machine and pay-off stand are mismatched, and the number of coil spools mounted on the pay-off stand is insufficient, restricting the production of this type of coil. The insufficient number of coil spools on the pay-off stand also limits the winding machine's capacity, affecting the winding capacity of the corresponding workstation. Summary of the Invention

[0003] The purpose of this invention is to provide a movable wire feeding frame and method for horizontal winding of transformers, which can be used together with the original wire feeding frame of the horizontal winding machine to increase the number of electromagnetic wires wound at the same time and complete the winding of 6-8 spiral coils; it can move laterally as a whole to increase the winding capacity of the corresponding workstation, improve the production capacity of the corresponding horizontal winding machine, improve the winding efficiency, and solve the above-mentioned technical problems existing in the prior art.

[0004] The technical solution of this invention is: A movable wire feeding frame for horizontal winding of a transformer includes a frame. A horizontally arranged upper support is provided on the frame, and two wire reels, namely wire reel one and wire reel two, are mounted on the upper support. A vertically arranged intermediate support is provided on the frame between wire reels one and two, and a wire reel three is mounted on the intermediate support.

A wire feeding mechanism is provided at the front of the frame and on the intermediate support. The wire feeding mechanism includes a wire feeding roller support, a wire feeding roller, and grooved wheels. The wire feeding roller has multiple grooved wheels, each with an annular wire groove. The two ends of the wire feeding roller are mounted on the front and intermediate supports of the frame via the wire feeding roller support. At the bottom of the frame are a drive wheel set, a speed transmission mechanism, a driven wheel set, and an asynchronous motor. The drive wheel set and the driven wheel set are arranged front and rear, and the asynchronous motor is connected to the drive wheel set via the speed transmission mechanism.

[0005] Furthermore, both the upper support and the intermediate support are provided with a roller shaft fixing plate, and the roller shaft fixing plate is provided with a roller shaft seat. The end of the roller shaft is set in the roller shaft seat through a roller shaft bushing.

[0012] This invention can meet the requirements of winding double-layer 6-8 spiral coils on horizontal winding machines with limited production capacity.

[0013] The beneficial effects of this invention are: when used with the original pay-off frame of the horizontal winding machine, it increases the number of electromagnetic wires wound simultaneously, completing the winding of 6-8 spiral coils; this invention can move laterally as a whole, increasing the winding capacity of the corresponding station, improving the production capacity of the corresponding horizontal winding machine, and improving winding efficiency.
