Description

Technical Field

[0001] This utility model relates to the technical field of anti-yarn twisting and dust prevention equipment, specifically an anti-yarn twisting and dust prevention device. Background Technology

[0002] When traditional yarn feeders introduce yarn into the yarn feeder, there are always corners and overlaps, causing the yarn to tangle and leading to machine downtime. Even when the machine is not running, prolonged downtime results in exposed yarn lint, requiring lengthy cleaning before restarting. Installing yarn sleeves not only improves aesthetics and uniformity but also avoids yarn tangling and long-term downtime hygiene issues. To ensure safe yarn transport, anti-twisting and dustproof equipment is often needed. Utility model patent application CN202222539892.5 discloses a yarn transport device for sock production. Through a separation component and sorting box, yarn boxes can be divided into undamaged and damaged categories, effectively separating damaged yarn boxes. The damaged yarn boxes are selected and moved to the left sorting box. The cleaning mechanism ensures the conveyor body is cleaned before use. During operation, the motor drives the telescopic rod to extend and retract, the cleaning cloth cleans the conveyor platform, and the movable rod moves the fixed rod up and down. The cleaning cloth sends dust to the dust collection box, which contains a dust storage container. According to the publicly available technical solution, existing anti-yarn twisting and dust prevention equipment has several drawbacks. First, when conveying yarn on the yarn rack, the pipe height and yarn conveying angle cannot be adjusted according to the yarn rack height, hindering the adaptability of the conveyor. Second, when the yarn breaks, it is difficult to quickly convey the yarn from one end of the pipe to the other, reducing work efficiency.

[0003] Therefore, designing a device to prevent yarn twisting and dust is the problem we need to solve. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a device for preventing yarn twisting and dust, comprising a horizontal tube 1 and a vertical tube 2. An inlet / outlet assembly is installed on the vertical tube 2, comprising an inlet tube 3 and an outlet tube 4. Connecting assemblies are installed at both ends of the horizontal tube 1, comprising elbows 5 and bends 6. A rotating assembly is installed inside the bend 6, comprising a retaining ring 7 and a ring groove 8. Locking assemblies are installed on both the inlet tube 3 and the outlet tube 4, comprising a retaining pin 10 and a spring 11. A yarn suction assembly is installed on the outlet tube 4, comprising a side opening 12 and a filter screen 14. The side opening 12 is welded to one side of the bottom end of the outlet tube 4, and the filter screen 14 is welded to the inner wall of the side opening 12. The diameter of the side opening 12 is the same as the diameter of the bottom end of the outlet tube 4. A sleeve is fitted on the outer side of the side opening 12. The device includes a retainer 13 with an internal thread on its inner wall. External threads 15 are present on the bottom end of the outlet tube 4 and the outer side of the side opening 12. The internal thread and external thread 15 engage. When the yarn breaks, the retainer 13 on the side opening 12 is unscrewed from the outer side of the side opening 12, and then the retainer 13 is installed on the outer side of the external thread 15 at the bottom end of the outlet tube 4. Air is then drawn into the outlet tube 4 through the side opening 12 using a suction device, causing the yarn to be drawn in through the inlet tube 3, then through the vertical tube 2 and horizontal tube 1, and finally into the inner side of the outlet tube 4. The yarn is drawn into the side opening 12 and filtered by the filter screen 14. The retainer 13 is then unscrewed from the bottom end of the outlet tube 4, and the yarn is pulled out from the bottom end of the outlet tube 4 to be fed into the inner side of the yarn nozzle. This allows the broken yarn to be quickly passed through the inner side of the pipe, improving the working efficiency of the equipment.

[0022] In this embodiment, there are two elbows 5, two bends 6, and two vertical pipes 2. The two elbows 5 are welded to both ends of the horizontal pipe 1. The two bends 6 are respectively fitted onto the outer sides of the two elbows 5. The retaining rings 7 are respectively installed at the top of the vertical pipes 2. The annular groove 8 is formed on the inner wall of the bottom of the bend 6. The top of the vertical pipe 2 is clamped onto the inner wall of the bottom of the bend 6. The annular groove 8 is fitted onto the outer side of the retaining ring 7. The inlet pipe 3 and the outlet pipe 4 are respectively fitted onto the outer sides of the two vertical pipes 2. One end of the retaining pin 10 is respectively installed on the outer side of the inlet pipe 3 or the outlet pipe 4. A retaining slot 9 is formed on the vertical pipe 2, and the retaining slots 9 are evenly distributed on the outer side of the vertical pipe 2. Both the inlet pipe 3 and the outlet pipe 4 have retaining grooves. The other end of the retaining pin 10 passes through the retaining groove and extends to the inner side of the retaining slot 9. One end of the retaining pin 10 is connected to the inlet pipe 3 or the outlet pipe via a spring 11. The outer side connection of 4 allows the vertical pipes 2 at both ends of the horizontal pipe 1 to be rotated on the outer side of the bend 5 via the elbow 6, according to the height and angle of the yarn frame, in order to adjust the angle between the horizontal pipe 1 and the vertical pipe 2. Then, according to the distance between the horizontal pipe 1 and the yarn feed outlet and the yarn nozzle, the locking pin 10 is pulled outward first, and then the inlet pipe 3 and the outlet pipe 4 are slid on the outer side of the vertical pipe 2 until the total length of the vertical pipe 2 and the inlet pipe 3 and the outlet pipe 4 are equal to the distance between the horizontal pipe 1 and the yarn feed outlet and the yarn nozzle. At this time, the spring 11 inserts the locking pin 10 into the bayonet 9, fixing the inlet pipe 3 and the outlet pipe 4 onto the two vertical pipes 2 respectively. The yarn is transported inside the pipe, avoiding twisting between different yarns and preventing dust from adhering to the yarn, ensuring the safe transport of the yarn. It can also be installed and used on different yarn frames, improving the adaptability of the equipment.

[0023] When in use, this anti-twisting and dustproof device allows the vertical pipes 2 at both ends of the horizontal pipe 1 to be rotated outside the bend 5 via the elbow 6, depending on the height and angle of the yarn frame. This adjusts the angle between the horizontal pipe 1 and the vertical pipe 2. Then, based on the distances of the horizontal pipe 1 to the yarn feed outlet and the yarn nozzle, the locking pin 10 is pulled outwards. Next, the inlet pipe 3 and outlet pipe 4 are slid outside the vertical pipe 2 until the total length of the vertical pipe 2, inlet pipe 3, and outlet pipe 4 is equal to the distances of the horizontal pipe 1 to the yarn feed outlet and the yarn nozzle. At this point, the spring 11 inserts the locking pin 10 into the locking slot 9, fixing the inlet pipe 3 and outlet pipe 4 to the two vertical pipes 2. The yarn is then transported inside the pipes, preventing twisting between different yarns and avoiding yarn adhesion. Dust is eliminated to ensure the safe transport of yarn and to allow for installation and use on different yarn racks, improving the equipment's adaptability. When the yarn breaks, the retainer 13 on the side opening 12 is unscrewed from the outside of the side opening 12, and then the retainer 13 is installed on the outside of the external thread 15 at the bottom of the outlet tube 4. Then, the suction device is used to suck air into the outlet tube 4 through the side opening 12, so that the yarn is sucked in through the inlet tube 3, then through the vertical tube 2 and the horizontal tube 1 and into the inside of the outlet tube 4, until the yarn is sucked into the side opening 12 and filtered and isolated by the filter screen 14. Then, the retainer 13 is unscrewed from the bottom of the outlet tube 4, and the yarn is pulled out from the bottom of the outlet tube 4 so that it can be fed into the inside of the yarn nozzle. This allows the broken yarn to be quickly passed through the inside of the pipe, improving the working efficiency of the equipment.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
