Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a textile mechanical device for preventing yarn from breaking and falling back. Background Art

[0002] Needle machine is the full name of the tool that processes raw materials such as thread, silk, and linen into silk thread and then weaves it into cloth.

[0003] During the knitting process of traditional knitting machines, the wire is easily broken during the stretching process due to the lack of synchronization between the wire and the meshing tooth device. In addition, the direction of the equipment is not uniform during operation, which easily causes the wire to become tangled, thus affecting production efficiency and product quality. Since the crochet hook may be worn or broken after long-term use, the replacement process of the crochet hook is relatively complicated and requires the disassembly of multiple parts, which is time-consuming and easy to damage other parts. This not only increases maintenance costs, but also affects production progress. Secondly, when the side plate on the crochet hook is damaged, there is no effective indication mechanism to help staff quickly identify the damaged parts, resulting in a slow replacement process and affecting production efficiency. When the equipment fails, the traditional device cannot be powered off in time, resulting in the continuation of the incorrect knitting work, increasing the rework rate and reducing product quality.

By integrating multiple components in the square box 36, a compact layout of the device is achieved, space is saved, installation and maintenance are facilitated, and maintenance convenience is improved.

[0026] Furthermore, two parallel first electric wires 33 are fixedly connected to the inner wall of the cylinder 3, the upper first electric wire 33 is electrically connected to the second electric wire 34, and the lower first electric wire 33 is electrically connected to the third electric wire 35. The lower surface of the workbench 1 is fixedly connected to a battery 45, the second electric wire 34 is electrically connected to the positive pole of the battery 45, and the third electric wire 35 is electrically connected to the negative pole of the battery 45. The two first electric wires 33 are arranged in a circular opening to avoid the need for too many wires for connection.

[0028] Furthermore, the inner wall of the cylinder 3 is fixedly connected with a plurality of annularly arranged LED lights 44, the number of which is the same as the number of hook needles 14, the positive poles of the plurality of LED lights 44 are electrically connected to the adjacent first copper sheet 12 on the left, and the negative poles of the plurality of LED lights 44 are electrically connected to the adjacent first copper sheet 12 on the right, so that each LED light 44 can be independently supplied with current through the copper sheet, thereby realizing individual control. Since the number of LED lights 44 is the same as the number of hook needles 14, this may mean that if any hook needle 14 is damaged, the adjacent LED lights 44 will give a prompt.

[0029] Furthermore, the second copper sheet 13 on the left is electrically connected to the first electric wire 33 above, the second copper sheet 13 on the left is electrically connected to the first electric wire 33 below, the second copper sheet 13 on the left is electrically connected to the first electric wire 33 above, and the second copper sheet 13 on the left is electrically connected to the first electric wire 33 below. The copper sheet can be used as a relay point to connect the upper and lower wires, so that the lower surface of the first conductive copper sheet 20 can contact the upper surfaces of the adjacent second copper sheet 13 and the first copper sheet 12 and power the LED light 44, at which time the staff is prompted that the equipment parts are damaged.

[0030] Furthermore, the two first conductive copper sheets 20 are located above the adjacent second copper sheet 13 and the first copper sheet 12, and at the same time, the distance between the two first copper sheets 20 and the second hook needle 14, the second copper sheet 13 and the two first copper sheets 12 is the same. When damage occurs, the lower surfaces of the two first conductive copper sheets 20 are in contact with the upper surfaces of the adjacent second copper sheet 13 and the first copper sheet 12 and the LED light 44 is powered, making it easier for staff to find damaged parts.

[0031] Furthermore, a rotating rod 47 is fixedly connected to the upper end of the right gear 9, a circular tray 48 is fixedly connected to the surface of the rotating rod 47, a coil 49 is placed on the upper end of the circular tray 48, and the inner wall of the coil 49 is rotatably connected to the surface of the rotating rod 47. The rotatable connection between the inner wall of the coil 49 and the surface of the rotating rod 47 can ensure that the coil 49 remains stable when the circular tray 48 rotates with the rotating rod 47, avoiding sliding or falling off due to rotational movement, and helping the coil 49 to maintain its position during rotation. The rotatable connection also allows the coil 49 to have a certain fine-tuning ability when subjected to external force, thereby reducing the risk of wire breakage due to pulling force.

[0032] Working principle: First, pass the hook 14 through the round hole 8, and then start the motor 10 to drive the two gears 9 to rotate and make the rotating rod 47 on the right gear 9 drive the coil 49 to rotate. Since the coil 49 and the meshing tooth 6 device rotate at the same time, the disconnection and retreat of the device are avoided. Then, when the hook 14 or the side plate 17 is damaged, when the side plate 17 is damaged, it will continue to move inward along the top of the hook 14 due to the insufficient length of the side plate 17. At this time, the plastic tube 18 on the surface of the side plate 17 drives the T-shaped plastic bracket 19 and the first conductive copper sheet 20 to move downward for a distance, so that the first conductive copper sheet 20 and the adjacent first copper sheet 12 and the second copper sheet are moved downward for a distance. The first conductive copper sheet 20 contacts the adjacent first copper sheet 12 and the second copper sheet 13, so that it supplies power to the LED lamp 44. When the upper part of the hook needle 14 is damaged, the side plate 17 will also move inward and make the first conductive copper sheet 20 contact with the adjacent first copper sheet 12 and the second copper sheet 13, so that the staff can identify the damaged parts easily. At the same time, the first conductive copper sheet 20 contacts the adjacent first copper sheet 12 and the second copper sheet 13, and the electromagnet 46 is energized through the action of the first neutral wire 43, so that the electromagnet 46 attracts the circular iron sheet 42 to release the second conductive copper sheet 40 and the third copper sheet 37, so that the equipment is powered off, so as to prevent the machine staff from not being able to see the damage of the equipment in time when the equipment is damaged, resulting in the equipment producing low-quality products.

[0033] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
