Description

Technical Field

[0001] This invention relates to the field of enameled wire production technology, and more specifically, to a fully automatic intelligent reel-changing and take-up device for flat wire enameling machines. Background Technology

[0002] Traditional enameled wire production line take-up machines require manual operation. The wire end is threaded onto the take-up reel, and the reel is started after manual verification. Once the set length is reached, a dedicated operator manually wraps a protective film around the wire to protect it. The wire and film are then manually cut, and the reel rotation is stopped, completing the take-up and film application process. When changing reels, the wire is manually pulled and wound onto another empty reel, the thread end is manually verified again, and the take-up reel is started again, repeating the take-up and film application process. While existing enameled wire machines are simple in structure and low in manufacturing cost, they require manual operation, resulting in high labor intensity and low production efficiency, failing to meet the needs of fully automated and efficient enameled wire production.

The first end gear 8 is fixedly mounted on one end of the first rotating shaft 7. The hinge groove 9 is rectangular, with its bottom fixedly mounted on the other end of the first rotating shaft 7. The reel-changing mounting tube 10 is polygonal, with one end hinged to the hinge groove 9 via a connecting shaft, thus hinged to the hinge groove 9. This allows the reel-changing mounting tube 10 to rotate unidirectionally relative to the hinge groove 9, improving the stability of the reel-changing mounting tube 10 as it rotates with the hinge groove 9 while still satisfying the automatic release function of the take-up reel 13 on the reel-changing mounting tube 10.

[0037] The coil locking mechanism includes a locking block 14, a locking transmission block 15, and a second automatic telescopic rod 16. The locking block 14 is rectangular and is a permanent magnet. One end of the locking block 14 is embedded in a locking through-hole on the side wall of the other end of the coil changing mounting tube 10, and the locking block 14 can slide axially back and forth within the locking through-hole. One end of the locking block 14 has a first inclined surface, and the other end has a second inclined surface.

When the second automatic telescopic rod 16 moves the locking transmission block 15 to the left, it pushes the locking block 14 outward in the locking through hole through the second inclined surface, thereby axially locking the take-up reel 13 onto the reel-changing mounting tube 10 through the first inclined surface. When the second automatic telescopic rod 16 moves the locking transmission block 15 to the right, the two locking blocks 14 automatically retract into the reel-changing mounting tube 10 through their opposite magnetic poles, facilitating the release and insertion of the take-up reel 13. Multiple sets of the winding reel components are provided, and these multiple sets of winding reel components are horizontally distributed at equal intervals on the sliding reel-changing support 6.

The first magnetic coil is fixedly embedded in the selection transmission tube 21. When the first magnetic coil is supplied with direct current to generate a magnetic field, it will push the selection transmission tube 21 to slide back and forth axially on the second rotating shaft 17, thereby driving the second end gear 22 to mesh and disengage with the first end gear 8. The winding seat 1 below the reel mounting component is provided with a sliding groove 24. The sliding groove 24 can receive the take-up reel 13 released from the reel changing mounting tube 10, so that the take-up reel 13 with a predetermined length of flat wire 55 wound on it can be automatically slid onto the conveyor belt, and the take-up reel 13 with a predetermined length of flat wire 55 wound on it can be transferred to the next process by the conveyor belt.
