When the staff notices the situation, an auxiliary component is set to reconnect the broken yarn, thereby improving work efficiency.

[0022] 2. The double-headed eddy current yarn-breaking detection device for the ring spinning machine pulls the connecting rod inside the sliding groove so that the connecting rod can slide on the top of the fixed disk. At the same time, the limit spring inside the sliding groove can cooperate and limit the connecting rod. When the broken yarn is placed on the outside of the spindle, the fixed disk is released, and the connecting rod pulls the fixed block under the action of the limit spring to cooperate with the spindle to press the broken yarn head to the outside of the spindle, thereby achieving the purpose of reconnecting the broken yarn. This solves the problem that the double-headed eddy current yarn-breaking detection device for the ring spinning machine can only detect but cannot cooperate to reconnect and fix the broken yarn, which may cause waste.

The detection component 2 includes a protection box 21 fixedly mounted on the side of the base plate 1, a plurality of eddy current sensors 22 fixedly mounted inside the protection box 21, an alarm 23 fixedly mounted on the side of the protection box 21, a circuit board 24 fixedly mounted on the inner wall of the protection box 21, a controller 25 fixedly mounted on the side of the circuit board 24, and an alarm indicator light 26 fixedly mounted on the top of the protection box 21.

[0030] By setting an eddy current sensor 22 inside the detection component 2 to monitor the rotation situation inside the fixed component 4 in real time, the yarn breakage situation can be detected. Once the yarn breakage is detected, the detection component 2 will emit an alarm sound through the alarm 23 and the alarm indicator light 26 will start flashing. When the staff notices the situation, the auxiliary component 5 is set to reconnect the broken yarn, thereby improving work efficiency.

[0031] In this embodiment, the fixing component 4 includes a wire ring 41 movably connected to the side of the steel collar 3 , a limit block 42 fixedly installed on the side of the wire ring 41 , and a bearing plate 43 movably connected above the limit block 42 .

[0032] By setting a wire ring 41 on the side of the steel collar 3 and cooperating with the eddy current sensor 22, during normal spinning operation, the wire ring 41 continuously cuts the magnetic lines of force and moves. When the yarn is broken, the wire ring 41 stops, and the eddy current sensor 22 receives different signals. The controller 25 performs differential processing and provides timely feedback.

[0033] In this embodiment, the auxiliary component 5 includes a sliding groove 51 opened inside the supporting plate 43, a limit spring 52 fixedly installed on the inner wall of the sliding groove 51, a connecting rod 53 fixedly installed on the side of the limit spring 52, a fixed plate 54 movably connected to the top of the connecting rod 53, and a fixed block 55 fixedly installed on the side of the fixed plate 54.

[0034] By setting a connecting rod 53 inside the sliding groove 51, when the yarn is broken, the broken yarn head is placed on the outside of the spindle 6, and the fixed disk 54 is rotated to use the fixed block 55 to re-fix the broken yarn on the outside of the spindle 6, thereby realizing the re-connection of the broken yarn.

[0035] In this embodiment, an opening groove 27 is opened on the side of the protective box 21 close to the base plate 1, and the height of the opening groove 27 is consistent with the height of the signal receiver position of the eddy current sensor 22. The controller 25 is connected to the circuit board 24 through the line, and the alarm 23 and the alarm indicator light 26 are respectively connected to the circuit board 24 through the line.

[0036] The protection box 21 is provided to protect the precision components inside the detection component 2, and an opening groove 27 is provided to cooperate with the eddy current sensor 22 to receive signals.

[0037] In this embodiment, the steel collar 3 is an I-shaped circular ring structure, and a limiting notch 411 for cooperating with the steel collar 3 is provided inside the wire ring 41. The wire ring 41 is fixedly installed through the limiting notch 411 and the steel collar 3 by buckles.

[0038] By setting a special steel collar 3 structure type, and the steel ring 41 is connected to the buckle of the steel collar 3, the steel ring 41 can shake on the outside of the steel collar 3 but not fall off. During normal operation, the steel ring 41 continuously vibrates on the outside of the steel collar 3. When the yarn is broken, the steel ring 41 is stably mounted on the outside of the steel collar 3.

[0039] In this embodiment, a locking groove is formed at the bottom of the carrying plate 43 , and the limiting block 42 is embedded in the locking groove and is slidably connected to the carrying plate 43 .

[0040] By setting a locking groove at the bottom of the supporting plate 43, when the supporting plate 43 is on the top of the steel collar 3, the limit block 42 can limit the movement path of the supporting plate 43. When the overall structure is connected to the spinning machine, the supporting plate 43 can be stably fixed on the top of the steel collar 3.

[0041] In this embodiment, the connecting rod 53 vertically passes through the notch opened at the top of the sliding groove 51 and is slidably connected to the sliding groove 51 . The top of the connecting rod 53 is embedded in the interior of the fixing plate 54 and is rotatably connected to the fixing plate 54 .

[0042] By setting a sliding groove 51 on the top of the fixed plate 54, the connecting rod 53 can slide on the top of the fixed plate 54, and the limit spring 52 inside the sliding groove 51 can cooperate and limit the connecting rod 53, and then cooperate with the spindle 6 to realize the reconnection of the broken yarn.

[0043] In this embodiment, a snap-fit ​​spindle 6 is provided on the top of the carrying plate 43 .

[0044] It should be noted that control devices such as circuit boards and controllers are existing technologies, and their specific structures and working principles are not described in detail in this article.

[0045] The working principle of the above embodiment is:

[0046] By setting an eddy current sensor 22 inside the detection component 2 to monitor the rotation situation inside the fixed component 4 in real time, during normal spinning operation, the wire ring 41 cooperates with the eddy current sensor 22, and the wire ring 41 continuously cuts the magnetic line movement. When the yarn is broken, the wire ring 41 stops, and the eddy current sensor 22 receives different signals. The controller 25 performs differential processing and then gives timely feedback, thereby realizing the detection of yarn breakage. Once the yarn breakage is found, the detection component 2 sends out an alarm sound through the alarm 23 and the alarm indicator light 26 starts flashing. When the staff notices the situation, the auxiliary component 5 is set to reconnect the broken yarn, thereby improving work efficiency.

[0047] In addition, by pulling the connecting rod 53 inside the sliding groove 51, the connecting rod 53 can slide on the top of the fixed plate 54, and the limit spring 52 inside the sliding groove 51 can cooperate and limit the connecting rod 53. When the broken yarn is placed on the outside of the spindle 6, the fixed plate 54 is released, and the connecting rod 53, under the action of the limit spring 52, pulls the fixed block 55 to cooperate with the spindle 6 to press the broken yarn head to the outside of the spindle 6, thereby achieving the purpose of reconnecting the broken yarn.

[0048] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
