Description

Technical Field

[0001] The utility model relates to the field of feeding, and more specifically, to a feeding mechanism of a drawing device for producing core-spun yarn. Background Art

[0002] Core-spun yarn is a special yarn structure. A drawing frame is used in the reproduction process of core-spun yarn to improve the uniformity and strength of the yarn. The drawing frame is a mechanical device used in the textile industry to combine multiple coarse yarns into a uniform yarn. Its main function is to combine multiple coarse yarns and form a uniform spun yarn through drafting, mixing and homogenization to improve the quality and uniformity of the yarn.

[0003] When currently processing core-spun yarns in parallel, multiple yarns need to be fed into the feeding system of the paralleling device. The yarns are then guided by the guiding structure in the feeding system and guided into the bundler, which bundles the multiple strands of yarn together to achieve the function of paralleling. When the guiding structure is used in the existing technology to guide the yarns, it can be guided normally when there are fewer yarns, but when there are more yarns, they are prone to tangling together. Although a device for separating the bundles is also provided on the guiding structure, the yarns themselves are relatively thin and fragile. Once tangled together, the yarns may break when passing through the device for separating the bundles. The subsequent process requires re-loading of the yarns, which in turn affects production efficiency.

[0004] Based on the above, the purpose of the present invention is to provide a feeding mechanism of a drawing device for producing core-spun yarn, so as to solve the above problems. Utility Model Content

[0023] Furthermore, the driving mechanism includes a motor 7 fixedly connected to the base 1, and the output shaft of the motor 7 is provided with a rotating shaft 8 with one end fixedly connected thereto, and the other end of the rotating shaft 8 is rotatably connected to the base 1, and multiple guide rods are fixedly connected to worm gears 9, and the rotating shaft 8 is fixedly connected to worm gears 10 whose number and position correspond to those of the worm gears 9.

[0024] Furthermore, the driven mechanism includes a missing gear 11 fixedly connected to the guide rod 2, wherein only half of the missing gear 11 has gear teeth, and the combing frame 4 is located on both upper and lower sides of the missing gear 11 and is fixedly connected to a rack 12.

[0025] Furthermore, several spray pipes 13 and atomizers 14 are fixedly connected to the base 1, the guide rod 2 is hollow, one end of the guide rod 2 is connected to the external water supply equipment, the other end of the guide rod 2 is connected to the water inlet of the atomizer 14, and the mist outlet of the spray pipe 13 is connected to the spray pipe.

[0026] Furthermore, a plurality of guide wheels 15 are rotatably connected to the base 1 , and a second limiting portion for limiting the position of the yarn is provided on the guide wheel 15 .

[0027] Working principle: When the core-spun yarn is being drawn, multiple yarn raw materials are respectively conveyed to the bundler through multiple guide rods 2 and limit parts 3. In this process, all guide rods 2 are driven to rotate by the motor 7, the rotating shaft 8, multiple worms 10 and multiple worm gears 9. The rotation direction of the guide rod 2 is the same as the movement direction of the yarn. The synchronous rotation can reduce the friction between the yarn and the guide rod 2, thereby reducing the generation of static electricity and the probability of yarn breakage during transportation. At the same time, the rotation of the guide rod 2 will drive the rotation of the missing gear 11. During the rotation of the missing gear 11, it will alternately engage with the racks 12 on the upper and lower sides and push the combing frame 4 to move back and forth. The mounting frame 6 then combs the yarn through the combing frame 4 and the combing rod 5 to prevent the yarn from being entangled with each other during movement, further reducing the probability of yarn breakage.

[0028] During this process, the external water supply equipment will input cold water into the guide rod 2, and the cold water will then pass through the guide rod 2 into the atomizer 14. The flowing cold water will take away the heat on the guide rod 2. The water mist generated by the atomizer 14 will then be sprayed onto the moving yarn through the spray pipe 13, so that the yarn remains moist to a certain extent, further reducing the generation and accumulation of static electricity.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
