A tension regulating device for warp-knitted fabrics to prevent slippage

Abstract

This utility model relates to the technical field of warp-knitted fabric production, and in particular to a tension adjustment device for warp-knitted fabric to prevent slippage. It includes a support frame with an adjustment plate mounted on top. When the movable block moves linearly under the drive of the threaded rod, the adjustment rod tilts at an angle as the movable block moves. This tilting of the adjustment rod pushes the adjustment plate to rotate around its connection point with the top of the support frame. The rotation of the adjustment plate causes the support rod and the fixed frame to move up and down, ultimately changing the height of the tension roller to adjust the tension of the warp-knitted fabric. A suitable positioning hole is selected according to the fabric width, and a fastening bolt is passed through the limiting ring and screwed into the positioning hole to firmly fix the limiting ring to the tension roller. The limiting rings on both sides can limit the lateral movement range of the fabric, preventing the fabric from slipping off both ends of the tension roller during tensioning. Furthermore, the fixing position of the limiting ring can be adjusted according to the needs of fabrics of different widths, improving practicality.

Description

Technical Field

[0001] This utility model relates to the technical field of warp-knitted fabric production, and in particular to a tension adjustment device for warp-knitted fabrics to prevent slippage. Background Technology

[0002] Warp knitting is an important branch of knitting technology. It involves feeding one or more sets of parallel yarns into working needles along the warp direction of the fabric, forming a continuous longitudinal loop structure through synchronous loop-forming technology. Its core principle lies in the warp beam feeding system driving multiple yarns to work together, so that each yarn moves laterally to the adjacent warp during the loop-forming process, forming an inclined loop backbone. This interlocking structure gives the fabric unique dimensional stability. Unlike the lateral loop-forming method of weft knitting, warp knitting can achieve a width of up to 210 inches through multi-comb synchronous loop-forming technology, significantly improving production efficiency. Warp-knitted fabrics form an independent longitudinal mesh base through chain weave, the warp plain weave gives lateral extensibility, the warp satin weave produces a twill effect, and the double-comb weave adjusts the thickness and mechanical properties through the superposition of front and rear comb movements. The patterned weave uses a jacquard device to achieve a three-dimensional relief effect. A fabric tension adjustment device is required during the production of warp-knitted fabrics.

[0003] Traditional fabric tension adjustment devices have a small tension control range, are cumbersome and inconvenient to operate, and cannot adjust the tension of warp-knitted fabrics according to the width of the fabric, which can cause the fabric to shift or fall off when tensioned. They are not very practical and therefore have certain drawbacks.

[0004] Therefore, in order to solve the above problems, this utility model provides a tension adjustment device for warp-knitted fabrics that prevents them from falling off. Utility Model Content

[0005] The purpose of this invention is to provide a tension adjustment device for warp-knitted fabrics that prevents them from falling off, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tension adjustment device for warp-knitted fabric to prevent slippage, comprising a support frame, an adjustment plate mounted on the top of the support frame, a fixed seat mounted on the wider outer side of the support frame, a threaded rod mounted between the inner sidewalls of the fixed seat, a movable block mounted on the outer ring surface of the threaded rod, an adjustment rod mounted on the top of the movable block, a support rod mounted on one outer end of the adjustment plate, a fixed frame mounted on one bottom end of the support rod, connecting seats symmetrically mounted at both ends of the bottom of the fixed frame, a tension roller mounted between the outer sides of the connecting seats, and limit rings provided at both ends of the outer ring surface of the tension roller.

[0007] Preferably, mounting brackets are symmetrically arranged at both ends of the support frame. An adjusting bolt is installed at one end of the mounting bracket. One end of the adjusting bolt passes through the inner side of the mounting bracket and is rotatably connected to a limiting plate. The outer ring surface of the adjusting bolt is threadedly connected to the inside of the mounting bracket.

[0008] Preferably, a servo motor is installed at one end of the fixed base. The output shaft of the servo motor passes through the interior of the fixed base and is connected to one end of the threaded rod. The outer ring surface of the threaded rod is threadedly connected to the interior of the movable block. Limiting grooves are symmetrically opened at both ends of the fixed base. Guide posts are installed at both ends of the movable block and inside the two limiting grooves.

[0009] Preferably, the top of the movable block is rotatably connected to the bottom end of the adjusting rod, the outer side of the adjusting plate away from the support rod is rotatably connected to the top end of the adjusting rod, and the bottom end of the adjusting plate is rotatably connected to the top of the support frame.

[0010] Preferably, a sleeve is slidably connected to the outside of the support rod, and a connecting rod is rotatably connected to one end of the sleeve. The end of the connecting rod away from the sleeve is rotatably connected to the outside of the support frame.

[0011] Preferably, a groove is provided on the top of the outer ring surface of the tension roller, and several positioning holes are symmetrically provided on both sides of the bottom end of the tension roller. A limiting block is installed on the inner side wall of the limiting ring and inside the groove. A fastening bolt is installed at the bottom end of the outer ring surface of the limiting ring, which passes through the limiting ring and is connected to the inside of the positioning hole.

[0012] In summary, this utility model has the following beneficial technical effects:

[0013] This anti-drop warp-knitted fabric tension adjustment device works as follows: When the movable block moves linearly under the drive of the threaded rod, the adjusting rod tilts at an angle as the movable block moves. Because the top of the adjusting rod is rotatably connected to the side of the adjusting plate away from the support rod, the change in the adjusting rod pushes the adjusting plate to rotate around its connection point with the top of the support frame. The rotation of the adjusting plate causes the support rod and the fixed frame to move up and down, ultimately changing the height of the tension roller, thereby adjusting the tension of the warp-knitted fabric. A suitable positioning hole is selected according to the fabric width, and the fastening bolt is passed through the limiting ring and screwed into the positioning hole. The limiting ring is firmly fixed to the tension roller through the threaded connection between the fastening bolt and the positioning hole. The limiting rings on both sides can limit the lateral movement range of the fabric, preventing the fabric from slipping off both ends of the tension roller during tensioning. Furthermore, the fixing position of the limiting ring can be adjusted according to the needs of different fabric widths, making it convenient to operate and highly practical.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 4 The present invention will be described in further detail below.

[0020] A tension adjustment device for warp-knitted fabric to prevent slippage, as described in reference Figure 1 - Figure 4 The system includes a support frame 1, an adjusting plate 2 mounted on the top of the support frame 1, a fixed seat 3 mounted on the wider outer side of the support frame 1, a threaded rod 4 mounted between the inner sidewalls of the fixed seat 3, a movable block 5 mounted on the outer ring surface of the threaded rod 4, an adjusting rod 6 mounted on the top of the movable block 5, a support rod 7 mounted on one outer end of the adjusting plate 2, a fixed frame 8 mounted on one bottom end of the support rod 7, connecting seats 9 symmetrically mounted at both ends of the bottom of the fixed frame 8, a tension roller 10 mounted between the outer sides of the connecting seats 9, and limit rings 11 provided at both ends of the outer ring surface of the tension roller 10.

[0021] Reference Figure 1 - Figure 2The support frame 1 has mounting brackets 12 symmetrically arranged at both ends of its outer side. An adjusting bolt 13 is installed at one end of the outer side of the mounting bracket 12. One end of the adjusting bolt 13 passes through the inner side of the mounting bracket 12 and is rotatably connected to the limiting plate 14. The outer ring surface of the adjusting bolt 13 is threadedly connected to the inside of the mounting bracket 12. When installing the support frame 1 onto the machine, the support frame 1 is first placed in a suitable position, and then the adjusting bolt 13 is rotated. Since the adjusting bolt 13 is threadedly connected to the inside of the mounting bracket 12, rotating the adjusting bolt 13 will cause it to move horizontally on the mounting bracket 12, thereby pushing the limiting plate 14 closer to the machine. When the limiting plate 14 is tightly fitted to the machine, the support frame 1 can be securely installed on the machine.

[0022] Reference Figure 1 - Figure 2 A servo motor 15 is mounted on one end of the fixed base 3. The output shaft of the servo motor 15 passes through the interior of the fixed base 3 and connects to one end of the threaded rod 4. The outer ring surface of the threaded rod 4 is threadedly connected to the interior of the movable block 5. Limiting grooves 301 are symmetrically formed at both ends of the fixed base 3. Guide posts 16 are installed at both ends of the movable block 5, located inside the two limiting grooves 301. After the servo motor 15 is started, its output shaft drives the threaded rod 4 to rotate. Because the threaded rod 4 is threadedly connected to the interior of the movable block 5, the rotation of the threaded rod 4 will cause the movable block 5 to tend to move horizontally. The guide posts 16 at both ends of the movable block 5 are embedded in the limiting grooves 301 at both ends of the fixed base 3. The guide posts 16 can only slide within the limiting grooves 301, thus restricting the rotational freedom of the movable block 5, so that the movable block 5 can only move horizontally. The movable block 5 can move linearly along the axis of the threaded rod 4. The top of the movable block 5 is rotatably connected to the bottom of the adjusting rod 6. The outer side of the adjusting plate 2 away from the support rod 7 is rotatably connected to the top of the adjusting rod 6. The bottom of the adjusting plate 2 is rotatably connected to the top of the support frame 1. When the movable block 5 moves linearly under the drive of the threaded rod 4, the adjusting rod 6 will tilt at an angle as the movable block 5 moves because the movable block 5 is rotatably connected to the bottom of the adjusting rod 6. Also, because the top of the adjusting rod 6 is rotatably connected to the side of the adjusting plate 2 away from the support rod 7, the change of the adjusting rod 6 will push the adjusting plate 2 to rotate around its connection point with the top of the support frame 1. The rotation of the adjusting plate 2 drives the support rod 7 and the fixed frame 8 to move up and down, ultimately changing the height of the tension roller 10, thereby adjusting the tension of the warp-knitted fabric.

[0023] Reference Figure 1 - Figure 2A sleeve 17 is slidably connected to the outside of the support rod 7. A connecting rod 18 is rotatably connected to one end of the sleeve 17. The end of the connecting rod 18 away from the sleeve 17 is rotatably connected to the outside of the support frame 1. When the support rod 7 moves up and down under the drive of the adjusting plate 2, the sleeve 17 will slide along the support rod 7. At the same time, since one end of the connecting rod 18 is rotatably connected to the sleeve 17 and the other end is rotatably connected to the support frame 1, the sliding of the sleeve 17 will cause the connecting rod 18 to rotate and change angle. The connecting rod 18 plays a guiding and stabilizing role in the movement of the support rod 7, preventing the support rod 7 from shaking or deviating during the movement, ensuring the stability and accuracy of the tension roller 10 in the process of adjusting the tension, and making the fabric tension adjustment more stable and reliable.

[0024] Reference Figure 3 - Figure 4 The tension roller 10 has a groove 1001 on the top of its outer ring surface. Several positioning holes 1002 are symmetrically arranged on both sides of the bottom end of the tension roller 10. A limiting block 19 is installed on the inner wall of the limiting ring 11, inside the groove 1001. A fastening bolt 20 is installed at the bottom end of the outer ring surface of the limiting ring 11, penetrating the limiting ring 11 and connecting to the positioning hole 1002. The limiting block 19 on the inner wall of the limiting ring 11 is slidably connected to the groove 1001 on the top of the outer ring surface of the tension roller 10, preventing the limiting ring 11 from sliding. The fabric rotates on the tension roller 10. Select the appropriate positioning hole 1002 according to the width of the fabric, pass the fastening bolt 20 through the limiting ring 11 and screw it into the positioning hole 1002. The limiting ring 11 is firmly fixed on the tension roller 10 by the threaded connection between the fastening bolt 20 and the positioning hole 1002. The limiting rings 11 on both sides can limit the lateral movement range of the fabric and prevent the fabric from slipping off both ends of the tension roller 10 during the tensioning process. The fixed position of the limiting ring 11 can be adjusted according to the needs of different width fabrics.

[0025] The implementation principle of the anti-drop warp-knitted fabric tension adjustment device of this utility model embodiment is as follows: When using this device, when installing the support frame 1 onto the machine, first place the support frame 1 in a suitable position, and then rotate the adjusting bolt 13. Since the adjusting bolt 13 is internally threadedly connected to the mounting frame 12, rotating the adjusting bolt 13 will cause it to move horizontally on the mounting frame 12, thereby pushing the limiting plate 14 closer to the machine. When the limiting plate 14 is tightly fitted to the machine, the support frame 1 can be securely installed on the machine. After the servo motor 15 is started, its output shaft drives the threaded rod 4 to rotate. Because the threaded rod 4 is internally threadedly connected to the movable block 5, the rotation of the threaded rod 4 will cause the movable block 5 to rotate. Block 5 tends to move horizontally, and the guide posts 16 at both ends of the movable block 5 are embedded in the limiting grooves 301 at both ends of the fixed seat 3. The guide posts 16 can only slide within the limiting grooves 301, thus restricting the rotational freedom of the movable block 5. This means that the movable block 5 can only move linearly along the axis of the threaded rod 4. When the movable block 5 moves linearly under the drive of the threaded rod 4, since the movable block 5 is rotatably connected to the bottom of the adjusting rod 6, the adjusting rod 6 will tilt at an angle as the movable block 5 moves. Also, since the top of the adjusting rod 6 is rotatably connected to the side of the adjusting plate 2 away from the support rod 7, the change in the adjusting rod 6 will push the adjusting plate 2 to rotate around its connection point with the top of the support frame 1. The rotation drives the support rod 7 and the fixed frame 8 to move up and down, ultimately changing the height of the tension roller 10, thereby adjusting the tension of the warp-knitted fabric. When the support rod 7 moves up and down under the action of the adjusting plate 2, the sleeve 17 slides along the support rod 7. At the same time, since one end of the connecting rod 18 is rotatably connected to the sleeve 17 and the other end is rotatably connected to the support frame 1, the sliding of the sleeve 17 will cause the connecting rod 18 to rotate and change angle. The connecting rod 18 guides and stabilizes the movement of the support rod 7, preventing the support rod 7 from shaking or deviating during the movement, ensuring the stability and accuracy of the tension roller 10 in the tension adjustment process, making the fabric tension adjustment more stable and reliable. (Limiting ring 1...) The limiting block 19 on the inner side wall is slidably connected to the slot 1001 at the top of the outer ring surface of the tension roller 10 to prevent the limiting ring 11 from rotating on the tension roller 10. Select a suitable positioning hole 1002 according to the width of the fabric, pass the fastening bolt 20 through the limiting ring 11 and screw it into the positioning hole 1002. The limiting ring 11 is firmly fixed on the tension roller 10 by the threaded connection between the fastening bolt 20 and the positioning hole 1002. The limiting rings 11 on both sides can limit the lateral movement range of the fabric and prevent the fabric from slipping off both ends of the tension roller 10 during the tensioning process. The fixed position of the limiting ring 11 can be adjusted according to the needs of different width fabrics, making it convenient to operate and more practical.
