[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0022] The weft breakage monitoring and stopping device of the knitting machine according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] As Figures 1 - 4 shown, the weft breakage monitoring and stopping device of the knitting machine according to the embodiment of the present invention may include a support component 1, a mounting plate 2, a plurality of monitoring components 3, a warning component 4, and a controller 5.

[0024] Among them, the mounting plate 2 is arranged on the support component 1, and a mounting bracket 20 is arranged on the mounting plate 2.

[0025] It should be noted that this device is located at the yarn concentration area on one side of the knitting machine, and the support component 1 is fixed on the ground on one side, so as to facilitate the weft breakage monitoring of multiple yarns.

[0026] A plurality of monitoring components 3 are respectively arranged on the mounting bracket 20. The monitoring component 3 may include an adjusting member 30, two fixed frames 31, two elastic telescopic members 32, a rotating roller 33, a first metal sheet 34, and a second metal sheet 35.

[0027] It can be understood that a plurality of monitoring components 3 respectively correspond to multiple yarns, that is, one yarn corresponds to one monitoring component 3, so as to ensure the weft breakage monitoring of multiple yarns by this device and ensure the quality of textile products.

[0028] Among them, the adjusting member 30 is arranged on the mounting frame 20, two fixing frames 31 are respectively arranged at the bottom of the adjusting member 30, two elastic telescopic members 32 are respectively arranged in the corresponding fixing frames 31, the end parts of the rotating rollers 33 are respectively rotatably arranged on the extending ends of the two elastic telescopic members 32, the first metal sheet 34 is connected to the extending ends of the two elastic telescopic members 32 and is located below the rotating rollers 33, and the second metal sheet 35 is arranged on the fixing frame 31 and is in sliding contact with the first metal sheet 34.

[0029] In the embodiment of the present application, the elastic telescopic member 32 is used for tension buffering of the yarn during the textile process and controlling the contact between the first metal sheet 34 and the second metal sheet 35 when the yarn breaks.

[0030] It can be understood that the adjusting member 30 can adjust the height of the fixing frame 31 on the mounting frame 20, so as to facilitate the adjusting member 30 to quickly adjust the tension of the yarn.

[0031] It can be understood that the yarn is arranged between the first metal sheet 34 and the rotating roller 33, and the yarn is in tight contact with the rotating roller 33. By the rotational arrangement of the rotating roller 33 on the elastic telescopic member 32, the friction between the yarn and the rotating roller 33 is reduced.

[0032] It should be noted that in this embodiment, the two ends of the rotating roller 33 extend into the fixing frame 31 respectively, so as to prevent the yarn from rotating and deflecting on the rotating roller 33 and rotating to the rotational connection between the rotating roller 33 and the fixing frame 31, thereby accelerating the wear of the yarn and causing the yarn to break.

[0033] The warning component 4 is arranged on the mounting frame 20, the controller 5 is arranged on the mounting plate 2 and is respectively connected to the warning component 4, the first metal sheet 34 and the second metal sheet 35, and the controller 5 is connected to the knitting machine.

[0034] It should be noted that in this embodiment, the first metal sheet 34 and the second metal sheet 35 are respectively connected by electric wires (not shown in the figure). After the first metal sheet 34 and the second metal sheet 35 come into contact, the signal of the circuit being connected is transmitted to the controller 5. The controller 5 controls the warning component 4 to give a warning and an alarm, and at the same time transmits the signal to the knitting machine. After receiving the signal, the knitting machine stops the machine operation, so as to realize the monitoring and shutdown of the yarn breakage of the knitting machine.

[0035] Specifically, during actual operation, relevant staff members pass multiple yarns through between the first metal sheet 34 and the rotating roller 33 respectively. After the yarns are installed on the knitting machine, the relevant staff operate the adjusting member 30 to make the yarns rotate and abut against the rotating roller 33, and the yarns lift the elastic telescopic member 32 upward, so that the first metal sheet 34 and the second metal sheet 35 are separated. When the device is started and a certain yarn breaks, the elastic telescopic member 32 extends to restore its initial position, so that the first metal sheet 34 and the second metal sheet 35 abut against each other, and the circuit of the electric wire connected to the first metal sheet 34 and the second metal sheet 35 is conducted. The signal of the circuit connection is transmitted to the controller 5, and the controller 5 controls the warning component 4 to issue a warning and an alarm. At the same time, the controller 5 transmits the signal to the knitting machine, and the knitting machine stops running after receiving the signal, so as to realize the monitoring and shutdown of the broken yarn of the knitting machine.

[0036] In an embodiment of the present invention, as Figure 1 、 Figure 2 and Figure 4 shown, the adjusting member 30 may include a threaded rod 300 and a slider 301.

[0037] Among them, the threaded rod 300 is threadedly connected to the mounting frame 20, the slider 301 is slidably connected to the mounting frame 20, and the slider 301 is rotatably connected to the threaded rod 300 and is located at the bottom of the threaded rod 300.

[0038] It can be understood that through the rotational connection between the threaded rod 300 and the slider 301, when the threaded rod 300 is screwed downward and rotated, the slider 301 does not rotate with the threaded rod 300, thus avoiding the situation that the slider 301 rotates and winds the yarn around the slider 301.

[0039] In an embodiment of the present invention, as Figure 1 、 Figure 3 and Figure 4 shown, the elastic telescopic member 32 may include a fixed cylinder 320, a spring 321 and a sliding block 322.

[0040] Among them, the fixed cylinder 320 is arranged in the fixed frame 31, one end of the sliding block 322 is slidably arranged in the fixed cylinder 320, the other end of the sliding block 322 is connected to the first metal sheet 34, the rotating roller 33 is rotatably connected to the sliding block 322, the spring 321 is arranged in the fixed cylinder 320, and one end of the spring 321 is connected to the sliding block 322, and the other end of the spring 321 is connected to the fixed cylinder 320.

[0041] It can be understood that through the setting of the spring 321, the sliding block 322 can be pushed to expand and contract, so that the sliding block 322 buffers the yarn during the textile process when the yarn is in a taut state. The sliding block 322 buffers the yarn through the deformation of the spring 321, thereby preventing the yarn from breaking. In addition, when the yarn breaks, through the elastic deformation recovery of the spring 321, the first metal sheet 34 and the second metal sheet 35 are abutted, so that the controller 5 transmits a stop signal to the knitting machine, realizing the monitoring of the yarn breakage of the knitting machine.

[0042] In an embodiment of the present invention, as Figure 1 、 Figure 3 and Figure 4 shown, the warning assembly 4 may include a plurality of indicator lights 40 and an alarm 41.

[0043] Among them, the plurality of indicator lights 40 are respectively arranged on the mounting frame 20, are respectively connected to the controller 5, and the plurality of indicator lights 40 are arranged corresponding to the plurality of monitoring assemblies 3.

[0044] It can be understood that after the yarn in a certain monitoring assembly 3 breaks, the corresponding indicator light 40 lights up, so as to facilitate the relevant staff to quickly check the broken yarn, thereby improving the work efficiency.

[0045] In an embodiment of the present invention, as Figure 1 、 Figure 3 and Figure 4 shown, the support assembly 1 may include a fixed block 10 and an electric telescopic rod 11.

[0046] Among them, one end of the electric telescopic rod 11 is arranged on the fixed block 10, and the mounting plate 2 is fixedly connected to the other end of the electric telescopic rod 11.

[0047] It can be understood that through the setting of the electric telescopic rod 11, the device is applicable to yarns of different heights, thereby improving the use effect of the device.

[0048] Specifically, during the actual operation process, relevant staff members pass multiple yarns through between the first metal sheet 34 and the rotating roller 33 respectively. After the yarns are installed on the knitting machine, the relevant staff members rotate the threaded rod 300 downward, driving the slider 301 and the fixed frame 31 to move downward, so that the yarns are rotationally abutted against the rotating roller 33 in the fixed frame 31, and the yarns lift the elastic telescopic member 32 upward, thus separating the first metal sheet 34 and the second metal sheet 35. When the device is started, when a certain yarn breaks, the elastic telescopic member 32 extends to restore its initial position, so that the first metal sheet 34 and the second metal sheet 35 are abutted. The circuit of the electric wire connected to the first metal sheet 34 and the second metal sheet 35 is turned on, and the signal of the circuit connection is transmitted to the controller 5. The controller 5 controls the indicator light 40 at the corresponding broken wire position to light up and controls the alarm 41 to give an alarm. At the same time, the controller 5 transmits the signal to the knitting machine, and after receiving the signal, the knitting machine stops the machine operation, thereby realizing the broken wire monitoring and shutdown of the knitting machine yarn.

[0049] In summary, the broken wire monitoring and shutdown device of the knitting machine in the embodiment of the present utility model can detect the broken wire of the yarn in the knitting machine, thereby ensuring the product quality and improving the production efficiency.
