Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for enameled wire production, in particular to an auxiliary device for producing enameled wire pay-off. Background Art

[0002] Due to the small diameter and low strength of the enameled wire, it is impossible to use the traditional pay-off rack to rotate the wire. Therefore, the current enameled wire pay-off processes usually use a reel to lay the wire flat and lead the wire end upward. During the pay-off process, the wire will continuously sweep the edge of the reel side plate, causing scratches on the wire surface, and even the wire will be cut by the edge of the reel side plate, causing waste and affecting production efficiency.

[0003] At present, each process in the production process will stop for adjustment due to various reasons. During the shutdown adjustment period, the wire tension will often be lost. At this time, the wire will become loose and fall under the action of gravity, which will cause the wire to become entangled or even knotted, affecting the subsequent smooth wire payout. Utility Model Content

[0004] The purpose of the utility model is to provide a wire-laying auxiliary device for producing enameled wires, so as to solve the problems raised in the above-mentioned background technology.

The two clamping plates 13 are assembled into a full circle to cover the large end surface of the outlet sleeve 12, and the lower corners of the contact edges of the two clamping plates 13 are in a smooth arc structure.

[0008] The support rod 7 is made of plastic material, and is composed of a vertical installation section, a horizontal section, an inclined section and a vertical section from left to right.

[0009] The clamp includes a clamp a8 and a clamp b9. The clamp a8 is fixed on the end of the vertical section of the support rod 7. There are two clamps b9 fixed on the inclined section of the support rod 7. The clamp a8 is fixed on the inlet end of the spring 10 so that the inlet port of the spring 10 faces the wire reel 1. The clamp b9 is fixed on the outlet end of the spring 10 so that the outlet port of the spring 10 faces upward.

The seat plate 3 is pressed on the upper end surface of the wire drum 1, and the circular boss 4 is clamped in the disk hole 2, that is, the seat plate 3 is positioned and assembled with the wire drum 1 by the boss and the disk hole. The center of the seat plate 3 is provided with a stepped hole 5. One end of the support rod 7 is rotatably connected in the stepped hole 5 through a bearing 6. The bearing 6 is installed in the stepped hole 5 and axially positioned by a retaining spring. The support rod 7 rotates along the center of the disk hole 2 of the wire drum 1. A spring 10 is fixed on the support rod 7 through a clamp. The inlet port of the spring 10 is inserted with an inlet sleeve 11, and the outlet port of the spring 10 is inserted with an outlet sleeve 12. A wire clamping structure is provided on the outlet sleeve 12. When the wire is paid off, the conductor 14 passes through the inlet sleeve 11, the spring 10 and the outlet sleeve 12 in sequence.

[0024] The wire clamping structure includes two semicircular clamping plates 13, which are symmetrically hinged on the large end surface of the outlet sleeve 12. The two clamping plates 13 are assembled into a full circle to cover the large end surface of the outlet sleeve 12, and the lower corners of the contact edges of the two clamping plates 13 are in a smooth arc structure, so that the two clamping plates 13 are convenient to open upward.

[0025] The support rod 7 is made of plastic material with a small moment of inertia, and is composed of a vertical installation section, a horizontal section, an inclined section and a vertical section from left to right.

[0026] The clamp includes a clamp a8 and a clamp b9, the clamp a8 is fixed on the end of the vertical section of the support rod 7, and there are two clamps b9 fixed on the inclined section of the support rod 7. The clamp a8 is fixed on the inlet end of the spring 10 so that the inlet port of the spring 10 faces the wire drum 1, and the clamp b9 is fixed on the outlet end of the spring 10 so that the outlet port of the spring 10 faces upward.

[0030] Finally, the equipment is turned on for production. During the wire-laying process, the conductor 14 drives the support rod 7 to rotate along the disk hole 2, the wire-inlet end of the spring 10 makes a sinusoidal motion, and the clamping plate 13 is lifted upward by the friction force of the conductor 14, and the conductor 14 passes through the outlet sleeve 12 smoothly; after pausing the wire-laying, the clamping plate 13 falls back by gravity and clamps the conductor 14.
