[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model discloses a magnetic attraction structure of a yarn breaking plate of a yarn feeder, comprising a yarn feeder body 1, a bracket 2 installed on the yarn feeder body 1, and a swing rod 3 swingably connected to the bracket 2, wherein the part of the swing rod 3 located inside the bracket 2 is connected to a mounting block 8, one end of the mounting block 8 is connected to a connecting piece 10, and the interior of the bracket 2 is provided with a touch switch 11 which cooperates with the connecting piece 10 to serve as a yarn breaking alarm, a mounting rod 4 is installed on the bracket 2, and a magnetic attraction mechanism is provided between the mounting rod 4 and the mounting block 8 to cause the swing rod 3 to swing.

[0018] The touch switch 11 may be a slot-type photoelectric sensor. The swing rod 3 drives the connecting piece 10 to move, which can cut off or connect the signal of the touch switch 11 to control the start and stop of the yarn feeder body 1.

[0019] Of course, the touch switch 11 can also be a contact switch or other switch, and the connecting piece 10 contacts the touch switch 11 to control the start and stop of the yarn feeder body 1.

[0020] Specifically, the magnetic attraction mechanism includes a first magnet 7 and a second magnet 9. The end of the mounting rod 4 is connected to a mounting seat 6, the mounting seat 6 is mounted with the first magnet 7, and the mounting block 8 is mounted with a second magnet 9 that cooperates with the first magnet 7 for magnetic attraction.

[0021] In the present embodiment, since the mounting seat 6 and the first magnet 7 arranged thereon are in a stationary state, while the rocker arm 3 can move, the arrangement of the second magnet 9 which magnetically attracts the first magnet 7 can make the rocker arm 3 have a tendency to move. Since the magnetic force between the magnets is related to the distance, when the yarn feeder body 1 is in a normal working state, one end of the rocker arm 3 connected to the mounting block 8 is away from the mounting seat 6. At this time, the distance between the first magnet 7 and the second magnet 9 is far, and the magnetic force generated is also small, so that the rocker arm 3 can operate normally under a smaller force, and has the characteristic of high sensitivity.

[0022] Specifically, the mounting rod 4 is movably arranged on the bracket 2 .

[0023] The mounting rod 4 is threadedly connected to the bracket 2 , and the relative distance between the first magnet 7 and the second magnet 9 can be changed by adjusting the position of the mounting rod 4 .

[0024] In this embodiment, the position of the mounting rod 4 can be adjusted by rotating the mounting rod 4, so that the maximum relative distance between the first magnet 7 and the second magnet 9 can be changed, thereby changing the magnetic attraction between the first magnet 7 and the second magnet 9, which can be adjusted and changed according to different yarns.

[0025] Specifically, a dust cover 5 covering the inner cavity of the bracket 2 is connected to the bracket 2 by screws.

[0026] The dust cover 5 is provided with an escape hole for facilitating the operation of the mounting rod 4 .

[0027] To sum up, the magnetic attraction structure of the yarn breaking plate of the yarn feeder controls the swing of the rocker arm 3 through the magnetic attraction principle. When the yarn is broken, it can quickly and efficiently cooperate with the touch switch 11 to control the start and stop yarn storage action of the yarn feeder body 1. Compared with the traditional structure, it is more efficient and has a faster response speed.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
