Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile processing technology, and specifically relates to a yarn feeding device for a knitting machine for thick fabric processing. Background Technology
[0002] A knitting machine is a mechanical device used to produce knitted fabrics. It creates fabrics with good elasticity and breathability by weaving yarns into loops and interlocking them.
[0003] In the textile processing industry, the production of thick fabrics (such as denim, wool, and canvas) typically requires the use of coarser yarns. Because of their larger diameter and higher weight per unit length, coarser yarns result in shorter single spools. The yarn feeding device, including the yarn cassette, is a crucial component of knitting machines, primarily used to store yarn bobbins and guide the yarn into the feeding system in an orderly manner. In actual production, yarn consumption is rapid, requiring frequent machine stops for replacement, which not only impacts production efficiency but also increases labor costs and is cumbersome to operate. To address these issues, we provide a yarn feeding device for knitting machines processing thick fabrics. Utility Model Content
[0004] The purpose of this invention is to provide a yarn feeding device for a knitting machine for thick fabric processing, in order to solve the problem mentioned in the background art that the yarn consumption rate is relatively fast, and workers need to frequently stop the machine to replace the new yarn, which not only affects production efficiency but also increases labor costs.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn feeding device for a thick fabric knitting machine, comprising a frame, a rotating shaft rotatably connected inside the frame via a first bearing, a disc fixedly sleeved on the surface of the rotating shaft, four crossbars bolted to one side of the disc, a limiting mechanism provided on one side of the disc, a yarn guiding mechanism provided on the surface of the rotating shaft, and a plug mechanism provided on the surface of the crossbars.
[0006] The limiting mechanism includes a sliding sleeve, the surface of which is fixedly connected to the frame. A limiting pin is slidably sleeved inside the sliding sleeve. A push plate is fixedly sleeved on the surface of the limiting pin. A spring is sleeved on the surface of the limiting pin. Four insertion holes that are adapted to the limiting pin are opened on one side of the disc.
[0007] Preferably, the cable management mechanism includes a second bearing, the inner diameter of which is fixedly sleeved with the rotating shaft, and a circular sleeve fixedly sleeved on the outer diameter of the second bearing. A support rod is bolted to the surface of the circular sleeve, and a cable management ring is fixedly connected to the other end of the support rod. A counterweight is provided on the surface of the circular sleeve, and a mounting bolt is sleeved inside the counterweight. The other end of the mounting bolt is threadedly connected to the circular sleeve.
[0008] Preferably, the plug mechanism includes a conical sleeve, the inside of which is slidably fitted with a crossbar, a mounting sleeve is fixedly connected to one side of the conical sleeve, and a fixing bolt is threadedly connected to the surface of the conical sleeve, with one end of the fixing bolt penetrating into the inside of the conical sleeve.
[0009] Preferably, bottom rods are bolted to both sides of the bottom of the frame, and support bolts are threaded to both ends of the bottom rods. Reinforcing blocks are bolted to both sides of the front and back of the frame, and the bottom of the reinforcing blocks is bolted to the bottom rods.
[0010] Preferably, the surface of the disk is provided with a ring, and a connecting rod is fixedly connected to the inner side of the ring, with the other end of the connecting rod fixedly connected to the disk.
[0011] In summary, this utility model has the following beneficial effects:
[0012] This device, with its four-spool pre-connection design, reduces downtime for yarn changes, avoids production interruptions, and significantly improves the continuity and output of thick fabric processing. It is especially suitable for high-consumption scenarios involving coarse yarn. The automatic yarn switching function reduces the need for manual intervention. The yarn guide ring automatically turns to the next spool of yarn under the tension of the yarn, and works with the counterweight to maintain balance, reducing the intensity of worker operations and manpower waste. The device adopts a quick-installation structure with a conical sleeve and fixing bolts, combined with a limit pin spring mechanism, making disc adjustment and yarn splice replacement more convenient. Workers only need to pull the limit pin and rotate the disc to complete the position adjustment, ensuring smooth yarn switching and avoiding tangling problems.
[0013] The device has a reasonable structural design. It utilizes the synergistic effect of the rotating shaft, bearings and yarn guide rings to ensure stable yarn tension. At the same time, it achieves a seamless transition through pre-knotting splicing, reducing yarn waste and improving resource utilization. The overall solution improves textile production efficiency while taking into account ease of operation and equipment stability. It is suitable for the needs of large-scale production of thick fabrics and has high practical value and promotion prospects. Attached Figure Description

A disc 3 is fixedly sleeved on the surface of the rotating shaft 2. Four crossbars 4 are bolted to one side of the disc 3. A limit mechanism 5 is provided on one side of the disc 3. A yarn guiding mechanism 6 is provided on the surface of the rotating shaft 2. A plug mechanism 7 is provided on the surface of the crossbars 4.
[0023] The limiting mechanism 5 includes a sliding sleeve 501, the surface of which is fixedly connected to the frame 1. A limiting pin 502 is slidably sleeved inside the sliding sleeve 501. A push plate 503 is fixedly sleeved on the surface of the limiting pin 502. A spring 504 is sleeved on the surface of the limiting pin 502. Four insertion holes 11 that are adapted to the limiting pin 502 are opened on one side of the disc 3.
[0024] refer to Figure 4 The yarn guiding mechanism 6 includes a second bearing 601, the inner diameter of which is fixedly sleeved with the rotating shaft 2, and a round sleeve 602 fixedly sleeved on the outer diameter of the second bearing 601. A support rod 603 is bolted to the surface of the round sleeve 602, and a yarn guiding ring 604 is fixedly connected to the other end of the support rod 603. A counterweight 605 is provided on the surface of the round sleeve 602, and a mounting bolt 606 is sleeved inside the counterweight 605. The other end of the mounting bolt 606 is threadedly connected to the round sleeve 602. By setting the yarn guiding mechanism 6, the yarn guiding ring 604 automatically turns to the next roll of yarn under the action of yarn tension.
[0025] refer to Figure 5 The plugging mechanism 7 includes a conical sleeve 701, which is slidably fitted inside the crossbar 4. An installation sleeve 702 is fixedly connected to one side of the conical sleeve 701, and a fixing bolt 703 is threadedly connected to the surface of the conical sleeve 701. One end of the fixing bolt 703 penetrates into the interior of the conical sleeve 701. By setting the plugging mechanism 7, it is possible to effectively limit the yarn roll.
[0026] refer to Figure 1 Both sides of the bottom of the frame 1 are bolted with bottom rods 8, and both ends of the bottom rods 8 are threaded with support bolts 9. Both sides of the front and back of the frame 1 are bolted with reinforcing blocks 10, and the bottom of the reinforcing blocks 10 is bolted to the bottom rods 8. By setting the reinforcing blocks 10, the frame 1 can be effectively reinforced.
[0027] refer to Figure 2 The surface of the disc 3 is provided with a ring 12, and a connecting rod 13 is fixedly connected to the inner side of the ring 12. The other end of the connecting rod 13 is fixedly connected to the disc 3. By providing the ring 12, the disc 3 can be rotated easily.
[0028] Brief description of usage: The user can place four spools of yarn on the surface of the crossbar 4, then connect the conical sleeve 701 and the mounting sleeve 702 to the crossbar 4, and tighten the fixing bolt 703 to limit and fix the conical sleeve 701. Then, tie the end of the first spool of yarn to the beginning of the second spool of yarn, then tie the end of the second spool of yarn to the beginning of the third spool of yarn, and then tie the end of the third spool of yarn to the beginning of the fourth spool of yarn. Then, pass the beginning of the first spool of yarn through the inside of the yarn guide ring 604 and connect it to the knitting machine. When the knitting machine is working, it pulls the yarn to knit. When the first spool of yarn is used up, the knitting machine pulls the yarn, causing the yarn to drive the yarn guide ring 604 to rotate to the position of the second spool of yarn. The yarn guide ring 604, through the cooperation of the support rod 603 and the second bearing 601, drives the circular sleeve. The 602 rotates on the surface of the rotating shaft 2. By setting a counterweight 605, the rotation balance of the sleeve 602 on the surface of the rotating shaft 2 is achieved. In order to adjust the position with the yarn even when the yarn tension is small, it provides sufficient adjustment time for the worker to rotate the disc 3 and prevent the yarn from getting tangled. The user can pull the limiting pin 502 to slide inside the sliding sleeve 501, so that the limiting pin 502 drives the push plate 503 to compress the spring 504. At the same time, the limiting pin 502 disengages from the inside of the insertion hole 11. Then, the ring 12 is rotated to drive the disc 3 to rotate on the surface of the rotating shaft 2. This also facilitates the yarn loading and knotting of the device. After adjustment, the spring 504 returns to its original position and drives the limiting pin 502 to insert into the inside of the insertion hole 11, thereby effectively facilitating the adjustment and limiting of the disc 3.
