Description

Technical Field

[0001] The utility model relates to the technical field of foil winding machines, and particularly relates to a foil coil winding device. Background Art

[0002] A foil coil is a layer coil formed by parallel winding of one or more wires, and its wire is usually a thin and wide copper foil or aluminum foil. Axially, the foil coil has only 1 turn, but has multiple turns radially. There will be an axial oil gap after winding several turns. This special structure makes the foil coil mainly applicable to transformers with low voltage and small capacity, especially small and medium-sized transformers with a capacity less than 2000 kVA.

[0003] The design of the foil coil helps to achieve more efficient electromagnetic energy conversion, and to a certain extent optimizes the performance and cost of the transformer. In addition, the foil coil also has excellent heat dissipation performance, which helps to maintain the stable operation of the transformer.

[0004] Generally, a foil coil winding device is used when winding a foil coil. However, in the prior art, when the raw material foil coil is wound to the tail, the foil raw material detaches from the unwinding device, and the unwinding device can no longer provide tension for the foil raw material. At this time, the foil raw material in the section from the winding device to the unwinding device loses tension control, resulting in phenomena such as loose winding and damaged bending of the foil raw material after this section is wound. In order to ensure the quality of the foil coil, generally, the foil raw material in this section is cut and discarded. However, the distance from the unwinding device to the winding device is generally several meters long, and all the foil raw material in this section is cut and discarded, resulting in waste of the foil raw material. Therefore, further improvement is needed to reduce the amount of discarded foil raw material. Summary of the Invention

[0069] In this implementation plan, the set foil shearing device 3 is used to cut off the foil raw material at the last end. When specifically cutting, the shearing reduction motor 3f drives the shearing transmission screw pair 3d to work, and then promotes the circular knife 3g to cooperate with the lower knife 3j to cut the foil raw material. In order to facilitate the fine adjustment of the shearing position, the lower tool holder 3e is movably arranged on the large frame 7, and then the connecting rod 8 is rotated by turning the handwheel, so as to achieve the purpose of finely adjusting the position of the foil shearing device 3 through the cooperation of the fine adjustment gear 9 and the rack teeth 3k.

[0070] For details, please refer to Figure 1 , Figure 8 and Figure 9 , the insulating paper cutting device 4 includes a cutting cross bar 4a, a cutting knife 4b, a cutting knife holder 4c and a cutting roller 4d. Both ends of the cutting cross bar 4a are arranged on both side edges of the large frame 7 through optical axis linear bearings, and the cutting knife 4b is movably arranged on the cutting knife holder 4c. The cutting knife holder 4c is movably arranged on the cutting cross bar 4a. The cutting roller 4d is arranged under the cutting cross bar 4a and its two ends are connected to the large frame 7 through bearings. And a cutting groove 4e cooperating with the cutting knife 4b is provided on the cutting roller 4d. A plurality of cutting grooves 4e are evenly arranged on the cutting roller 4d, and at least one set of cutting knife holders 4c is provided.

[0071] In this implementation scheme, the insulating paper cutting device 4 is used for trimming the insulating paper. During the specific operation, the worker sets the cutting tool holder 4c to a proper position and installs the cutting tool 4b. The cutting tool 4b cooperates with the cutting groove 4e arranged on the cutting roller 4d to achieve the trimming work of the insulating paper.

[0072] For details, please refer to Figure 1 and Figure 10 The winding device 5 includes a main winding box 5a, a winding shaft 5b, a winding support frame 5c, and a winding reduction motor 5d. The winding reduction motor 5d is arranged in the main winding box 5a. The winding support frame 5c is fixedly connected to the large frame 7. One end of the winding shaft 5b is connected to the output shaft of the winding reduction motor 5d, and the other end is movably connected to the winding support frame 5c.

[0073] In this implementation scheme, the winding reduction motor 5d drives the winding shaft 5b to rotate, so as to realize the rotation of the foil winding die arranged on the winding shaft 5b, and further realize the winding work of the foil type coil.

[0074] Working principle: First, before the formal operation, the staff installs the foil raw material roll, insulating paper raw material roll, etc. according to the requirements, and pulls out the single-layer foil raw material on the foil raw material roll and fixes it to the foil winding die installed on the winding device 5 through the unwinding device 2, the foil cutting device 3, and the constant tension device 6. The insulating paper raw material roll is installed on the layer insulating unwinding device, and then the end is pulled out and fixed to the foil winding die through the insulating paper cutting device 4, and the equipment is started. The winding device 5 provides the power for winding. At the same time, the unwinding device 1 synchronously unwinds the foil raw material roll, and the winding device 5 winds the foil raw material and the layer insulating paper onto the foil winding die.

[0075] When the raw material on the foil raw material roll breaks away from the foil raw material roll, the unwinding device 1 loses the acting force on the foil raw material. At this time, the constant tension device 6 is started. At this time, the telescopic rod of the upper top cylinder 6bg moves, which drives the operating rod 6bh to move, and then drives the crankshaft 6be to rotate, so that the eccentric wheel 6bf rotates, and then pushes the lower pressing roller 6ba in the direction of the main gear 6bd. Then, the sub-gear 6bb meshes with the main gear 6bd, and the rotation power is provided by the lower pressing reduction motor 6bc to drive the lower pressing roller 6ba to rotate. At this time, the lower pressing roller 6ba cooperates with the lower roller 6a to press the foil raw material, and a tension is given to the foil raw material between the winding device 5 and the constant tension device, ensuring that this section of the foil raw material will not be loose and reducing the loss and waste of the foil raw material.
