DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-5 As shown, an online self-inspection device for a yarn pulling mechanism includes a base 1, characterized in that: three U-shaped threading grooves 2 are installed on the upper side of the base 1 and are spaced apart from each other, and a movable baffle 3 is hinged on the side of the U-shaped threading groove 2, a defect recognition device is installed between the two U-shaped threading grooves 2 on the left, and a broken thread recognition device is installed between the two U-shaped threading grooves 2 on the right;

[0023] The defect identification device includes a rear support frame 4, which is located at the rear side of the upper part of the base 1, and a plurality of rear line wheels 5 are rotatably installed on the front side of the rear support frame 4 and are spaced apart from each other. A front support frame 6 is installed on the upper front side of the base 1, and a slide bar 7 is installed between the front support frame 6 and the rear support frame 4. A slider 8 is slidably installed on the upper side of the slider 7, and a plurality of front line wheels 9 are rotatably installed on the rear side of the slider 8. The front line wheels 9 match the rear line wheels 5 and are staggered. An industrial camera 10 is installed on the upper sides of the front line wheels 9 and the rear line wheels 5, and a transmission component is connected between the slider 8 and the movable baffle 3;

[0024] The broken thread identification device comprises a broken yarn sensor 11 . A controller 12 is installed on the upper side of the base 1 . The controller 12 is electrically connected to the broken yarn sensor 11 and the industrial camera 10 .

[0025] Annular grooves are provided on the surfaces of the front thread wheel 9 and the rear thread wheel 5. When the utility model is in use, the transmission assembly makes the slider 8 be in front of the slide bar 7, and the movable baffle 3 blocks the opening of the U-shaped threading groove 2. The yarn enters the U-shaped threading groove 2 on the left side, and is alternately wound between the front thread wheel 9 and the rear thread wheel 5, and passes out from the inside of the two U-shaped threading grooves on the right side. The yarn is located between the yarn break sensors 11. The industrial camera 10 can quickly visually identify the color and short lint of the yarn, and transmit the signal to the controller 12. The yarn break sensor is a device that can identify yarn breakage. If the yarn has defects such as yarn breakage, color deviation and short lint, the controller 12 can control the equipment to stop running.

[0026] like Figure 3 As shown, when the yarn needs to be replaced, the transmission assembly makes the slider 8 be in front of the slide bar 7. At this time, the front thread wheel 9 is located behind the rear thread wheel 5, and the transmission assembly makes the movable baffle 3 in an open state, and the U-shaped threading groove 2 is in an open and exposed state. The staff only needs to pass the yarn from the left U-shaped threading groove 2, and pass between the front side of the front thread wheel 9 and the rear side of the rear thread wheel 5, and finally pass it out from the middle U-shaped threading groove 2 and the right U-shaped threading groove 2 respectively. At this time, the transmission assembly can be controlled to move the slider 8 forward, so that the yarn can resume the state of being alternately wound between the front thread wheel 9 and the rear thread wheel 5, and the movable baffle 3 blocks the opening of the U-shaped threading groove 2 again.

[0027] The industrial camera 10 and the broken wire sensor can identify defects such as yarn breakage, color deviation and short fibers on the upper side of the traction mechanism, realize automated detection and production, and reduce the density of workers. The front and rear distributed front and rear wire wheels 9 and rear wire wheels 5 can increase the detection area of ​​the yarn under the industrial camera 10 and improve the recognition accuracy. The slider 8 sliding forward and backward and the movable baffle 3 can simplify the threading steps when changing the yarn, which helps to improve production efficiency.

[0028] The transmission assembly includes a screw rod 13, which is installed between the front support frame 6 and the rear support frame 4 for rotating forward and backward. A motor 14 is installed on the rear side of the rear support frame 4. The output end of the motor 14 is transmission-connected to the screw rod 13, and the screw rod 13 is threadedly connected to the slider 8. A push rod 15 is fixed to the side of the slider 8. A telescopic rod 16 is transmission-connected to the lower side of the movable baffle 3, and the lower side of the telescopic rod 16 is hinged to the lower side of the push rod 15.

[0029] When the yarn needs to be replaced, the slider 8 is at the rear side of the screw rod 13. At this time, the movable baffle 3 is in an open state on the side of the U-shaped threading groove 2. When the yarn is replaced, the output end of the motor 14 drives the screw rod 13 to rotate and drives the slider 8 to slide forward. The push rod 15 can change the angle of the movable baffle 3. When the slider 8 is at the frontmost side of the slide bar 7, the movable baffle 3 just covers the opening of the U-shaped threading groove 2. The telescopic rod 16 is used to cope with the distance expansion and contraction between the upper side of the telescopic rod and the lower side of the push rod 15 when the movable baffle 3 rotates.

[0030] The transmission assembly can ensure that the movable baffle 3 and the slider 8 can achieve accurate and synchronous operation, thereby improving the convenience of use of the utility model.

[0031] A diffuser plate 17 is installed on the lower side of the front spool 9 and the rear spool 5 , and an LED lamp 18 is installed on the lower side of the diffuser plate 17 .

[0032] The cooperation of the LED lamp 18 and the diffuser plate 17 makes the background of the yarn brighter and more uniform, prevents interference from external light, improves the recognition accuracy of the industrial camera 10, and thus improves the textile quality of the textile machine.

[0033] A wire clamping assembly is also installed on the right side of the yarn break sensor 11, and the wire clamping assembly includes a lower support plate 19, which is fixedly connected to the base 1, and a cylinder 21 fixedly connected to the base 1 is installed on the upper side of the lower support plate 19, and the lower side of the output end of the cylinder 21 is transmission-connected to an upper pressure plate 20.

[0034] A rubber pad 22 is installed on the lower side of the upper pressing plate 20 and the upper side of the lower supporting plate 19 , and a plurality of anti-skid protrusions are arranged on the upper side of the rubber pad 22 at intervals on the left and right.

[0035] When the utility model works normally, the cylinder 21 is in a shortened state, the upper pressure plate 20 and the lower support plate 19 are in a separated state, and the cylinder 21 is connected to an external compressor. When the yarn break sensor 11 detects a signal of yarn breakage, the signal is transmitted to the controller 12. The controller 12 can control the equipment to stop running. At the same time, the controller 12 controls the output end of the cylinder 21 to extend quickly, so that the upper pressure plate 20 presses the yarn downward.

[0036] The cooperation between the cylinder 21, the upper pressure plate 20 and the lower support plate 19 enables the upper pressure plate 20 and the lower support plate 19 to clamp the yarn when the yarn breaks, making it convenient for the staff to find the thread ends and avoid the yarn from being entangled with other yarns. The rubber pad 22 and the anti-slip bumps can increase the friction on the yarn and reduce the impact of the upper pressure plate 20 on the lower support plate 19 when working, thereby reducing vibration and noise.

[0037] An audible and visual alarm 23 electrically connected to the controller 12 is installed on the upper side of the base 1 .

[0038] When the industrial camera 10 identifies a yarn defect or the yarn break sensor 11 identifies a yarn break, a signal is transmitted to the controller 12. The controller 12 can trigger the sound and light alarm 23 and continuously emit an alarm tone. The sound and light alarm 23 can promptly transmit alarm information to surrounding staff so that they can take corresponding safety measures.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
