If the breakage of the spindle position can be detected in time and effectively, the breakage of the machine can be handled in the shortest time. It can not only reduce the workload of the spindle operator, but also effectively improve the production efficiency of the enterprise, reduce costs and increase benefits. At present, an automatic yarn breakage detection and feeding stop device is used in the spinning section of the textile factory. After the yarn breaks, the feeding stop device will be activated immediately to stop feeding the coarse yarn and reduce material loss. For example, a single spindle feeding stop device of a spinning machine disclosed in Chinese utility model patent 2023216755203, Figure 1 As shown, however, the feeding stop device is not stable in actual application, is inconvenient to install and debug, and cannot be manually controlled in case of power failure or special circumstances. Therefore, a feeding stop device for a spinning frame with high stability is proposed to solve the above problems. Utility Model Content

A secondary spring is provided on the left side of the trigger so that the top of the trigger abuts against the movable piece, and the right side of the trigger is clamped with the electromagnet. When the electromagnet is actuated, it drives the trigger to actuate, thereby releasing the movable piece. The electromagnet is mounted on a PCB board, and a single chip microcomputer is provided on the PCB board to connect with an external circuit to receive an external signal to control the electromagnet. The electromagnet of this technical solution adopts a pull-type design, and the overall design is symmetrical, which has stronger stability.

The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 2-6 As shown, in order to solve the problems of low stability and inability to manually control the existing spinning frame feeding stop device, a spinning frame feeding stop device with high stability is provided, including a movable sheet 3 running through a housing 1 and an upper cover 2, and an adjusting groove 31 for installing a C-mouth piece 7 is provided at the front end of the movable sheet 3, as shown in FIG. Figure 3 As shown, the C-mouth piece 7 is driven by the movable piece 3 to brake the rubber roller of the spinning frame. A main spring 33 is installed in the middle of the movable piece 3, which is in contact with the housing 1. The main spring 33 is used to store force on the movable piece 3. A trigger 4 is provided below the movable piece 3, and the trigger 4 is in contact with the bottom of the movable piece 3. The trigger 4 clamps the stored force movable piece 3. The bottom convex block 42 of the trigger 4 extends to the outside of the housing 1, which is convenient for the user to handle manually. A secondary spring 41 is provided on the left side of the trigger 4 so that the top of the trigger 4 is in contact with the movable piece 3, and the right side of the trigger 4 is clamped with the electromagnet 5. When the electromagnet 5 is actuated, it will drive the trigger 4 to actuate, thereby releasing the movable piece 3. The electromagnet 5 is installed on the PCB board 6, and the PCB board 6 is provided with a single-chip microcomputer connected to the external circuit to receive external signals to control the electromagnet 5. The electromagnet 5 of this technical solution adopts a pull-type design, and the overall symmetrical design is adopted, which has stronger stability. At the same time, the convex block 42 can be manually dialed to realize manual control of the trigger 4 under special circumstances. The main spring 33, the auxiliary spring 41, the trigger 4 and the electromagnet 5 are all installed on the central plane of the shell 1, and the trigger 4 is installed on the left end of the shell 1, located in the center of the movable piece 3, further improving the stability of the movable piece 3 when working.

[0020] like Figure 3 As shown, a handle 32 is provided at the right end of the movable piece 3 to facilitate pushing and pulling the movable piece 3. The PCB board 6 is electrically connected to the external sensor and the central processing unit through a double 6-pin connector 61.

[0021] like Figure 4 , 5As shown, the electromagnet 5 includes an iron core 51, a coil 52, a sleeve 53 and a bracket 54. The iron core 51 is cylindrical and installed in the sleeve 53. One end of the iron core 51 is clamped with the trigger 4. The coil 52 wraps the sleeve 53. The sleeve 53 and the coil 52 are fixed in the bracket 54.

[0022] In order to have a more thorough and comprehensive understanding of the disclosed content of the utility model, the principle thereof is further explained below in combination with the usage method.

[0023] In actual use, the C-mouthpiece 7 is installed on a suitable adjustment groove 31, such as Figure 1 After installation, it needs to be debugged before power is turned on to ensure that it works properly. Figure 6 As shown, during power-off debugging, the movable sheet 3 is pushed to the left, the main spring 33 is compressed, and the blocking bar at the bottom of the movable sheet 3 is clamped by the top of the trigger 4. At this time, the protrusion 42 of the trigger 4 is toggled, and the movable sheet 3 moves to the right under the elastic force of the main spring 33, thereby driving the C-mouth piece 7 to rotate and then clamp the rubber roller, so that the coarse yarn feeding is stopped. After the debugging is completed, it is electrically connected to the external sensor and the central processor through the dual 6PIN connector 61, and the power is turned on for debugging again. When the power is turned on, the trigger 4 is driven to run through the electromagnet 5, and it can be put into operation after it is correct. In summary, the utility model adopts a central axis symmetrical structure, which effectively increases the stability of the product and reduces the deformation; when the feeding is stopped, the electromagnet 5 adopts a pull-type design, and the trigger 4 is changed from the original middle part to the front part, which increases the stability and reduces the defective rate; the trigger 4 adopts an electric and manual redundant design, which is convenient for working under special circumstances and effectively improves the overall reliability.
