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] A textile machine is the full name for a 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 textile machinery, the coil and the meshing tooth device are out of sync, which can easily cause the wire to break during the stretching process. In addition, the direction of the equipment is not uniform during operation, which can easily cause the wire to tangle, thus affecting production efficiency and product quality. After the side plate of the traditional device is worn, the replacement process is 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. When the side plate is damaged, the traditional device has 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. For this reason, we propose a textile machinery device with anti-yarn breakage and retraction to solve the above problems. Summary of the Invention

[0018] Thirdly, in the present invention, when the side panel is damaged, it will continue to move inward along the top of the side panel due to insufficient length. At this time, the plastic tube on the surface of the side panel drives the T-shaped plastic bracket and the first conductive copper sheet to move downward for a distance, so that the first conductive copper sheet contacts the adjacent first copper sheet and the second copper sheet, so that it can power the LED lamp, making it easier for staff to identify damaged parts and replace them.

[0019] Fourthly, the present invention energizes the electromagnet by contacting the first conductive copper sheet with the adjacent first and second copper sheets through the action of the first neutral wire, so that the electromagnet attracts the circular iron sheet to release the second conductive copper sheet and the third copper sheet, thereby cutting off the power supply to the equipment, thus avoiding the equipment from continuing to work when damaged, causing errors in knitting work, reducing rework, and improving product quality.

[0043] Furthermore, the limiting device includes a limiting base 21, which is located between the two shells 4. A square through groove 24 matching the first square hole 22 is provided on the surface of the limiting base 21. The square through groove 24 and the inner wall of the first square hole 22 are slidably connected with the same square tube 25. The inner wall of the square tube 25 is slidably connected with two symmetrically arranged limiting plates 26. One end of the two limiting plates 26 passes through the inner wall of the square tube 25 and extends to the outside. The inner wall of the square tube 25 is fixedly connected with two symmetrically arranged square fixing blocks 27. Both side walls of the two square fixing blocks 27 are fixedly connected with a first spring 28.

The inner wall of the square tube 25 rotates It is dynamically connected with an elliptical rotating block 29, and the other end of the elliptical rotating block 29 is fixedly connected with a polygonal rod 30. The surface of the polygonal rod 30 is slidably connected with a square plate 31. The surface of the polygonal rod 30 is sleeved with a second spring 32. One end of the second spring 32 is fixedly connected to the inner wall of the square tube 25, and the other end of the second spring 32 is rotatably connected to the side wall of the square plate 31.

[0044] Furthermore, the trigger device includes a square box 36, which is fixedly connected to the upper surface of the workbench 1, and the inner wall of the square box 36 is fixedly connected with two groups of symmetrically arranged third copper sheets 37, and the interior of the square box 36 is provided with two symmetrically arranged strip rubber plates 38, and the upper surfaces of the two strip rubber plates 38 are fixedly connected with rubber tubes 39, and the surface of the rubber tubes 39 is fixedly connected with a second conductive copper sheet 40, and the upper surface of the square box 36 is fixedly connected with two symmetrically arranged circular tubes 41, and the lower ends of the circular tubes 41 pass through the upper surface of the square box 36 and extend to the interior, and the upper ends of the rubber tubes 39 are fixedly connected with circular iron sheets 42, and the inner walls of the two circular tubes 41 are fixedly connected with electromagnets 46, and the surfaces of the circular iron sheets 42 are slidably connected to the inner walls of the circular tubes 41, through the two groups of symmetrically arranged third copper sheets 37, the strip rubber plates 38, the rubber tubes 39 and the second conductive copper sheet 40. The electric copper sheet 40 ensures the uniform response and stability of the device when triggered. The strip rubber plate 38 can absorb and isolate external impacts, reduce damage to internal sensitive components, and improve the durability and reliability of the device. The second conductive copper sheet 40 is fixedly connected to the surface of the rubber tube 39 to ensure a good conductive path when triggered, which is convenient for signal transmission and detection. The electromagnet 46 on the inner wall of the circular tube 41 can control the movement of the circular iron sheet 42 to achieve a precise triggering mechanism. At the same time, the use of the electromagnet 46 also facilitates automatic control. The sliding connection design between the circular iron sheet 42 and the inner wall of the circular tube 41 can reduce friction, extend the service life of the device, and respond quickly when triggered. By integrating multiple components in the square box 36, a compact layout of the device is achieved, saving space, facilitating installation and maintenance, and improving the convenience of maintenance.

[0045] Furthermore, two parallel first wires 33 are fixedly connected to the inner wall of the cylinder 3. The upper first wire 33 is electrically connected to the second wire 34, and the lower first wire 33 is electrically connected to the third wire 35. The lower surface of the workbench 1 is fixedly connected to a battery 45. The second wire 34 is electrically connected to the positive pole of the battery 45, and the third wire 35 is electrically connected to the negative pole of the battery 45. The two first wires 33 are arranged in a circular opening to avoid the need for too many wires for connection. The two first wires 33 arranged in a circular opening can reduce the complexity of connecting the wires, thereby simplifying the overall wiring process. Since the number of wires is reduced, the material cost can be reduced, and the space occupied by the wires can be reduced, making the equipment more compact. Reducing the connection points can reduce the failure points and improve the reliability of the system. Fewer wire connections make maintenance and inspection more convenient and quick.

[0046] Furthermore, the two electromagnets 46 are electrically connected to the same first live wire 43, the other end of the first live wire 43 is electrically connected to the second live wire 50, the inner wall of the cylinder 3 is fixedly connected to the second live wire 50, the live wire end of the second live wire 50 is electrically connected to the first copper sheet 12 on the left, and the neutral wire end of the second live wire 50 is electrically connected to the first copper sheet 12 on the right, which can ensure that the two electromagnets 46 are powered by the power supply at the same time, and the balanced distribution of current is achieved through the second live wire 50 on the inner wall of the cylinder 3. The first copper sheets 12 on the left and right are respectively connected to the live wire end and the neutral wire end of the second live wire 50, which can provide a stable voltage difference, ensuring that the electromagnet 46 can work normally and can disconnect the power supply and stop the machine in time when parts are damaged.

[0047] Furthermore, the inner wall of the cylinder 3 is fixedly connected to a plurality of annular LED lights 44. The number of LED lights 44 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 first copper sheet 12 adjacent to the left, and the negative poles of the plurality of LED lights 44 are electrically connected to the first copper sheet 12 adjacent to the right. This ensures that each LED light 44 receives an independent current supply through the copper sheet, thereby enabling individual control. Since the number of LED lights 44 is the same as the number of hook needles 14, it is possible that if any hook needle 14 is damaged, the adjacent LED light 44 will provide a warning.

[0048] Furthermore, the second copper sheet 13 on the left is electrically connected to the first wire 33 above, the second copper sheet 13 on the left is electrically connected to the first wire 33 below, the second copper sheet 13 on the left is electrically connected to the first wire 33 above, and the second copper sheet 13 on the left is electrically connected to the first 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 surface 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 reminded that the equipment parts are damaged.

[0049] Furthermore, the two first conductive copper sheets 20 are located above the adjacent second copper sheet 13 and the first copper sheet 12, and the distance between the two first conductive copper sheets 20 and the second copper sheet 13 and the first copper sheet 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 power is supplied to the LED light 44, making it easier for staff to find the damaged parts.

[0050] Furthermore, a rotating rod 47 is fixedly connected to the upper end of the right gear 9, and 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 rotational 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 tension.

[0051] Working principle: First, pass the hook through the circular hole 8 and connect it to the hook 14, then start the motor 10, 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 device is prevented from breaking and retreating. Then, when the hook 14 or the side plate 17 is damaged, when the side plate 17 is damaged, due to the insufficient length of the side plate 17, it will continue to move inward along the top of the hook 14. 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 side plate 17 will also move inwards and make the first conductive copper sheet 20 contact with the adjacent first copper sheet 12 and the second copper sheet 13, so that it can supply power to the LED lamp 44. When the upper part of the hook needle 14 is damaged, the side plate 17 will also move inwards 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. At the same time, the first conductive copper sheet 20 is in contact with 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, thereby preventing 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.

[0052] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one 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 is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
