Description

Technical Field

[0001] This utility model belongs to the field of pay-off machines, specifically relating to pay-off machines for knitted fabrics. Background Technology

[0002] In the knitting process of fabric weaving, a yarn feeding machine is often needed to feed the yarn for weaving onto the weaving table.

[0003] Currently, existing yarn feeding machines for knitted fabrics can only feed single yarns and cannot handle the knitting patterns of multi-colored knitted fabrics, resulting in poor versatility.

[0004] Therefore, to address the problem that existing yarn feeding machines for knitted fabrics are not suitable for knitting multi-colored knitted fabrics and thus have low versatility, a yarn feeding machine for knitted fabrics can be designed. An extension column is added to the positioning column, and positioning holes are opened on the yarn spools. A second support plate with a matching limit rod that matches the positioning hole is placed at the top of the bottommost yarn spool. Yarn spools of different colors are stacked together to achieve synchronous yarn feeding. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment: a yarn feeding machine for knitted fabric includes a support base 1; it also includes a first support plate 2, a positioning post 3, and an extension post 4. The positioning post 3 is fixedly connected to the top of the first support plate 2. The extension post 4 is connected to the internal threaded rod of the positioning post 3. The extension post 4 is composed of a stud and a positioning rod fixedly connected to the top of the stud. The positioning rod has a screw hole that matches the screw 17. A yarn spool 5 is placed on the first support plate 2 and sleeved on the outside of the positioning post 3. A limit groove 6 is provided on the yarn spool 5. A bottom end is provided on the top of the first support plate 2 that is close to the top of the yarn spool 5. The second support plate 7 is sleeved on the outside of the positioning post 3. A limiting rod 8 matching the limiting groove 6 is fixedly connected to the second support plate 7. An extension post 4 is installed in the positioning post 3 and fixed by a threaded connection. The limiting rod 8 matching the upper limit groove 6 of the bobbin 5 is fixedly connected to the second support plate 7 close to the top of the lower bobbin 5. This allows the bobbin 5 to be stacked from bottom to top, so that the first support plate 2 can drive the multiple bobbin 5 above to rotate. This enables the feeding of multiple types of yarn when only one feeding machine is used.

[0025] Please see Figure 1 and Figure 4In this embodiment, a lifting column 9 with a lifting groove on its surface is fixedly connected to the left side of the first support plate 2. A lifting platform 10 matching the lifting groove is slidably connected inside the lifting column 9. The lifting platform 10 is fixedly connected to the left end of the second support plate 7. The lifting platform 10 moves up and down inside the lifting column 9 to change the height of the second support plate 7 fixedly connected to the lifting platform 10 according to the height of the spool 5. This makes the second support plate 7 close to the top of the spool 5. Together with the first support plate 2, it applies force to the middle spool 5 from both above and below, so that the two spools 5 are clamped and fixed to the first support plate. Between support plate 2 and support plate 7, it can rotate together with support plate 2. U-shaped fixing grooves 11 are provided on the front and rear sides of the lifting column 9, passing through the front and rear plates of the lifting column 9. A circular fixing groove 12 matching the U-shaped fixing groove 11 is provided on the lifting platform 10. Fixing bolts 13 pass through the U-shaped fixing groove 11 and the circular fixing groove 12 in sequence. Nuts with their rear ends tightly attached to the front end of the lifting plate are screwed on the fixing bolts 13. The fixing bolts 13 passing through the U-shaped fixing groove 11 and the circular fixing groove 12 can fix the lifting platform 10 on the lifting column 9 to prevent it from moving.

[0026] Please see Figures 4-6 In this embodiment, the support base 1 has a storage groove 14, in which a motor 15 is installed. A support ring 16 is fixedly connected to the output end of the motor 15. The design of the storage groove 14 allows the support base 1 to protect the motor 15. The output end of the motor 15 can drive the support ring 16 to rotate. A first support plate 2 is disposed above the support ring 16. A screw 17 passing through the first support plate 2 is fixedly connected to the support ring 16. A threaded sleeve is threadedly connected to the outside of the screw 17. Tightening the threaded sleeve can... The first support plate 2 is fixed on the support ring 16. The motor 15 can provide power for the rotation of the first support plate 2. The support base 1 is fixedly connected with the front and rear opposite mounting plates 18. The mounting plate 18 is fixedly connected with the positioning wheel 19. The positioning wheel 19 is fixedly connected with the mounting seat 20 with the surface having anchor holes on both sides. The positioning wheel 19 can position and limit the direction and position of the appearance. The positioning wheel 19 is fixed to the mounting plate 18 by the screw passing through the anchor hole. Multiple positioning rings are installed according to the number of wire drums 5 to realize multi-line conveying.

[0027] During operation, the worker first aligns the No. 1 support plate 2 with the stud on the support ring 16 and inserts it so that the bottom end of the No. 1 support plate 2 is tightly against the top end of the support ring 16. Then, the threaded sleeve is turned to fix the No. 1 support plate 2 onto the support ring 16. Next, according to the weaving requirements, the corresponding number of bobbins 5 are taken out and fitted onto the outside of the positioning post 3. Then, the lifting platform 10 is aligned with the lifting groove on the lifting post 9 and moved down until the bottom end of the No. 2 support plate 7 is tightly against the top end of the bobbins 5. Then, the fixing bolt 13 is passed through the U-shaped fixing groove 11 and the circular fixing groove 12 and the nut is tightened to make it tightly against the lifting post 9, thus fixing the No. 2 support plate 7. Finally, the extension post 4 is taken out, the stud is inserted into the positioning post 3 and rotated. To achieve threaded fixation, a new bobbin 5 is fitted onto the outside of the extension column 4. The limiting rod 8 at the top of the second support plate 7 is aligned with the limiting groove 6 on the bobbin 5, and the bobbin 5 is installed on the second support plate 7. Then, a new second support plate 7 is taken out, placed above the bobbin 5, and fixed. This process is repeated to install all the bobbins 5. The screws that serve as anchoring columns are passed through the anchoring holes on the mounting base 20. The corresponding number of positioning wheels 19 are installed on the bobbin 5. The yarn on the bobbin 5 is then pulled out and passed around the positioning wheels 19 to be fixed to the knitting device. The motor 15 is started, and the motor 15 drives the first support plate 2 and the multiple bobbins 5 above it to rotate, so that multiple lines are fed at the same time. At the same time, the knitting device is started to process the knitted fabric.

[0028] Through the above steps, an extension column 4, which is fixed by a threaded connection, is installed inside the positioning column 3, and a limiting rod 8, which matches the upper limit groove 6 of the bobbin 5, is fixedly connected to the second support plate 7, which is close to the top of the lower bobbin 5. This allows the bobbins 5 to be stacked from bottom to top, so that the first support plate 2 can drive the multiple bobbins 5 above to rotate. This enables the uniform feeding of bobbins 5 for various types of yarns, allowing the loom to feed multiple types of yarns using only one feeding machine. This improves the versatility of the feeding machine and solves the problem that existing feeding machines for knitted fabrics are not suitable for knitting and processing of multi-colored knitted fabrics, resulting in low versatility.
