Description

Technical Field

[0001] The utility model belongs to the technical field of textile machinery, and in particular relates to a textile machinery rabbit head connecting device capable of detecting broken wires. Background Art

[0002] In the modern chemical fiber spinning production process, a spinning machine is needed to wind the spinning. The rabbit head is a key component of the spinning machine. The rabbit head can slide horizontally relative to the spinning machine so that the silk thread is evenly wound on the bobbin.

[0003] When the existing rabbit head is in use, the spinning is prone to fall off from the rabbit head, so that the spinning cannot be evenly wound on the bobbin, and then the winding needs to be restarted. And when the spinning breaks, it cannot be detected and a signal is sent in time. In general, the existing spinning machine rabbit head is prone to spinning falling off and cannot detect broken wires, resulting in a long winding time and low efficiency.

[0004] For example, the patent document with the authorization announcement number CN212531775U discloses an anti-slipping rabbit head for a texturizing machine. The rabbit head is fixedly connected to the steel sheet. The rabbit head is a rotating body with a disconnected part on the circumference. A wire-passing channel is formed on the inner circumference of the rabbit head. The disconnected part constitutes the entrance for the wire to enter the wire-passing channel and is connected to the wire-passing channel. The main body has an insertion part inserted below the upper surface of the steel sheet and a lap located above the upper surface of the steel sheet. The insertion part and the lap are distributed in sequence in the extension direction of the wire-passing channel, and the outer diameter of the lap is larger than the outer diameter of the insertion part. The technical solution disclosed in the patent document cannot solve the technical problems described above. Utility Model Content

[0018] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0019] It should be noted that, in the following embodiments, the “first” and “second” mentioned do not represent an absolute distinction in structure and / or function, nor do they represent a sequential order of execution, but are merely for the convenience of description.

[0020] like Figures 1 to 3 As shown, the utility model provides a spinning machine rabbit head connection device capable of detecting broken wires, comprising a wire guide 3 for guiding a wire bundle and a pressure switch 1 located below the wire guide 3, wherein the pressure switch 1 is configured to contact the descending wire guide 3 and be triggered when a wire bundle breaks.

[0021] Specifically, if Figure 1 and Figure 2As shown, a mounting hole is provided on the yarn guide 3, a guide member 9 is provided in the mounting hole, and a guide hole for the yarn bundle to pass through is provided on the guide member 9. The pressure switch 1 is electrically connected to the signal generator 2. During the production process, when the yarn is broken during spinning, the end of the yarn guide 3 is pressed down and contacts the pressure switch 1. The pressure switch 1 is triggered after receiving pressure, and the signal generator 2 sends a signal to remind the production personnel to deal with the broken yarn, which can reduce the time required for spinning and winding, and improve production efficiency.

[0022] like Figures 1 to 3 As shown, the guide member 9 includes an inner frame 7 and a protective layer 8 that wraps the inner frame 7 and is used to contact the wire bundle, and the material of the protective layer 8 is ceramic. The material of the inner frame 7 is metal, and the protective layer 8 of the ceramic material is wear-resistant, so that the guide member 9 can be used for a long time before replacement.

[0023] like Figures 1 to 3 As shown, the opening on the guide member 9 for the wire bundle to pass through is controlled by the baffle rod 10, and the baffle rod 10 is rotatably connected to the guide member 9. One end of the baffle rod 10 is connected to the lower end of the guide member 9 through a rotating shaft, and the rotation center line of the baffle rod 10 is parallel to the moving direction of the wire bundle when passing through the guide member 9. A torsion spring is arranged on the rotating shaft, and the elastic force of the torsion spring on the baffle rod 10 to make it rotate downward enables the baffle rod 10 to always keep the opening of the guide member 9 closed in the absence of external force. After the baffle rod 10 rotates upward, the opening of the guide member 9 can be opened; after the baffle rod 10 rotates downward, the other end of the baffle rod 10 contacts the guide member 9, and the baffle rod 10 rotates into place to close the opening of the guide member 9. A protective layer 8 is also arranged on the outer surface of the baffle rod 10, and the material of the protective layer 8 is ceramic.

[0024] like Figure 1 and Figure 2 As shown, the wire guide 3 has certain elastic properties, and the wire guide 3 is made of an elastic, non-deformable metal wire. The wire guide 3 includes a first connecting section 5 and a second connecting section 6 connected to each other, the pressure switch 1 is located below the second connecting section 6, the lower end of the first connecting section 5 is fixedly connected to the slide bar 4, one end of the second connecting section 6 is fixedly connected to the upper end of the first connecting section 5, and the other end of the second connecting section 6 is used to contact the pressure switch 1, and the second connecting section 6 has a tendency to rotate downward relative to the first connecting section 5. The mounting hole is set at a position between the two ends of the second connecting section 6, and the guide member 9 is inserted into the mounting hole to be tightly matched with the second connecting section 6, and the guide member 9 can be replaced.

[0025] During the production process, the production personnel pass the spinning yarn under the yarn guide 3, and then move the yarn bundle so that the yarn bundle enters the guide hole through the opening of the guide member 9; in the initial state, the end of the second connecting section 6 is in contact with the pressure switch 1;

[0026] The spinning machine is started, the spinning begins to wind, and the filament bundle begins to tighten. When the filament bundle shows a certain tension, it contacts the guide 9, and then the second connecting section 6 of the filament guide 3 is lifted up to a certain height, so that the second connecting section 6 is rotated upward by a certain angle; then the slide bar 4 starts to move back and forth left and right in the horizontal direction, and the slide bar 4 drives the filament guide 3 to move synchronously, and the filament guide 3 pulls the spinning to move left and right, so that the spinning is evenly wound on the bobbin.

[0027] During the operation of the spinning machine, when the yarn bundle is normal, the yarn guide 3 is pulled upward by the yarn bundle, causing the yarn guide 3 to be separated from the pressure switch 1, and the pressure switch 1 is in a closed state. When the yarn bundle breaks, the second connecting section 6 recovers to its original state at a faster speed due to the elastic force generated by the deformation, and the second connecting section 6 rotates downward to press the pressure switch 1, and the pressure switch 1 is activated, which can power the signal generator 2 to send a signal.

[0028] When the guide member 9 reaches the replacement time, it is only necessary to pull the old guide member 9 off the wire guide 3, align the new guide member 9 with the mounting hole of the wire guide 3, and then press it in, so that the wire guide 3 will clamp the new guide member 9.

[0029] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
