Abstract
Description
Technical Field

[0002] In textile production, yarn feeding is a crucial step in the orderly transport of yarn-wound bobbins to the next process (such as weaving, dyeing, and winding). Its level of automation and operational continuity directly impact overall production efficiency. Existing yarn feeding equipment often leaves residual yarn ends tangled on the surface of the yarn bobbin after yarn cutting, and manual cleaning is inefficient, increasing labor intensity and affecting subsequent processes. Furthermore, process connections are disjointed: yarn fixing, cutting, end cleaning, and conveying are mostly independent operations with low automation integration, resulting in a slow overall production pace and difficulty in meeting the demands of efficient continuous production.

When the yarn bar 3 moves with the conveying component to below the rotating clamp 6, the first pneumatic telescopic rod 4 pushes the rotating clamp 6 down and fixes the top of the yarn bar 3. The motor 5 drives the rotating clamp 6 to rotate the yarn bar 3. At this time, the second pneumatic telescopic rod 7 drives the take-up needle 9 to rise. The tip of the take-up needle 9 scrapes off the yarn on the surface of the rotating yarn bar 3 to achieve yarn separation and prepare for the subsequent thread end processing process.
[0015] This utility model provides a technical solution: the conveying assembly includes a first limiting plate 101, a second limiting plate 102 and a conveying plate 20; A first limiting plate 101 is fixedly installed above the workbench 1. The first limiting plate 101 has a hollow center. A second limiting plate 102 is provided at the hollow center of the first limiting plate 101 above the workbench 1.

A conveyor plate 20 is provided on the side of the second limiting plate 102 near the hook assembly below it, and a limiting post 19 is provided on the top side of the second limiting plate 102 away from the conveyor plate 20.
[0016] The above technical solution involves: a first limiting plate 101 with a central cutout is fixedly installed above the workbench 1, and a second limiting plate 102 is installed at the cutout, forming a gap structure between the first limiting plate 101 and the second limiting plate 102. The yarn holder 2 is placed in this gap to achieve lateral limiting. A conveyor plate 20 is installed below the second limiting plate 102 on the side near the hook assembly. The rotation of the conveyor plate 20 drives the yarn holder 2 and the yarn bar 3 to move along the gap. A limiting post 19 is installed on the top of the second limiting plate 102 on the side away from the conveyor plate 20 to block and limit the yarn holder 2 and the yarn bar 3 as they move to the end position, ensuring accurate positioning and providing a stable foundation for subsequent operations.
[0017] This utility model provides a technical solution: the wire assembly includes a third pneumatic telescopic rod 11, a movable cover 13, a wire suction tube 14, a fourth pneumatic telescopic rod 15, a first suction tube 18, and a second suction tube 21; A third pneumatic telescopic rod 11 is provided on the inner side wall of the mounting bracket 103. The bottom of the third pneumatic telescopic rod 11, away from the mounting bracket 103, is fixedly connected to one end of the connecting plate 12. The other end of the connecting plate 12 is fixedly connected to a movable cover 13. The middle of the movable cover 13 is sleeved with the lower end of the suction tube 14. The middle of the suction tube 14 is fixedly connected to the mounting plate 10. A fourth pneumatic telescopic rod 15 is provided between the suction tube 14 and the third pneumatic telescopic rod 11 on the mounting plate 10. A movable blade 16 is connected to the end of the fourth pneumatic telescopic rod 15 near the suction tube 14. The movable blade 16 is located in the opening on one side of the upper end of the suction tube 14. A probe head 1401 is provided above the movable blade 16 on the inner wall of the suction tube 14. A fixed blade 17 is provided on the inner wall of the suction tube 14 opposite to the movable blade 16. A first suction tube 18 is provided at the top of the suction tube 14. A second suction pipe 21 is provided directly below the movable cover 13 on the workbench 1 and below the conveyor plate 20; The yarn holder 2 is a yarn holder with a round base at the bottom and a protrusion at the top, and a first through hole 201 is provided inside the yarn holder 2; The yarn bar 3 is a yarn bar with a small opening at the top and a large opening at the bottom, and a second through hole 301 is provided inside the yarn bar 3.
[0018] Through the above technical solution: when the yarn bar 3 moves with the conveyor plate 20 to directly below the movable cover 13, the third pneumatic telescopic rod 11 drives the movable cover 13 to descend via the connecting plate 12, so that it covers the top of the yarn bar 3; at this time, the first suction pipe 18 starts suction, sucking the thread end on the surface of the yarn bar 3 into the suction pipe 14 through the movable cover 13; when the probe 1401 detects the thread end, the fourth pneumatic telescopic rod 15 pushes the movable blade 16 to move towards the fixed blade 17, cutting off the thread end; then the first suction pipe 18 stops suction, and the second suction pipe... 21. Initiate suction and use airflow to guide the cut thread ends through the second through hole 301 of the yarn bar 3 and the first through hole 201 of the yarn holder 2 in sequence, thereby achieving directional guidance and fixation of the thread ends. The structure design of the bottom round seat and the top protrusion of the yarn holder 2, combined with the gap between the first limiting plate 101 and the second limiting plate 102, ensures the stability of the yarn holder 2 during the conveying process. The structure of the yarn bar 3 with a small opening at the top and a large opening at the bottom, as well as the through setting of the second through hole 301, facilitates the smooth passage of the thread ends and the connection of subsequent processing steps.
[0019] The working principle of this utility model is as follows: The base of the yarn holder 2 is placed on the surface of the workbench 1. The protrusion on its top is embedded in the gap formed by the first limiting plate 101 and the second limiting plate 102. Initially, the yarn bar 3 is placed on the yarn holder 2. The conveying plate 20 of the conveying assembly rotates, driving the single yarn holder 2 and the yarn bar 3 to move below the rotating chuck 6. The first pneumatic telescopic rod 4 of the hook assembly pushes the motor 5 and the rotating chuck 6 to descend and clamp the yarn bar 3. The motor 5 drives the rotating chuck 6 to rotate the yarn bar 3. At the same time, the second pneumatic telescopic rod 7 retracts, and the thread take-up needle 9 is lifted through the connecting block 8 to cut the yarn and throw it away. Then the conveyor plate 20 rotates again, sending the yarn bar 3 and the yarn holder 2 to the bottom of the movable cover 13; the third pneumatic telescopic rod 11 of the wire assembly pushes the movable cover 13 down through the connecting plate 12 to cover the top of the yarn bar 3, the first suction pipe 18 (connected to the negative pressure generator built into the workbench 1) starts suction, sucking the thread end into the suction pipe 14; after the sensor 1401 in the suction pipe 14 detects the thread end, the fourth pneumatic telescopic rod 15 pushes the movable blade 16 and the fixed blade 17 to cooperate to cut the thread end, at the same time the first suction pipe 18 stops suction, the second suction pipe 21 (connected to the negative pressure generator built into the workbench 1) starts instantly, sucking the thread end into the first through hole 201 of the yarn holder 2 through the second through hole 301 of the yarn bar 3 to complete the threading; The processed yarn holder 2 and yarn bar 3 are continuously rotated by the conveyor plate 20 and pushed by the subsequent yarn holder 2, and move step by step along the gap between 101 and 102 until they are blocked and positioned by the limiting post 19; finally, they are picked up and placed into the next process by the gripping and delivery component 22, realizing the fully automated and continuous operation of the entire process.
