Description

Technical Field

[0001] This utility model relates to the field of knitted fabric production, specifically a knitted fabric tensioning mechanism. Background Technology

[0002] Knitted fabrics are fabrics formed by bending yarns into loops and interlocking them using knitting needles. The difference between knitted and woven fabrics lies in the form of the yarns within the fabric. Knitting is divided into weft knitting and warp knitting. Knitted fabrics are widely used in clothing fabrics and linings, home textiles, and other products, and are loved by consumers. The production process of knitted fabrics requires the use of a tensioning mechanism.

[0003] According to Chinese Patent No. CN220149784U, a pulling device for knitted fabrics is disclosed. This utility model uses a base as the support of the device. The fabric is unwound by an unwinding roller, then passes through the outside of a pulling roller on one side, then upwards and through the space between the compression rollers, then through another pulling roller and finally wound up by a take-up roller. The two pulling rollers pull the fabric in sections on both sides. An adjustment mechanism is activated to adjust the position of the two pulling rollers to change the pulling force on the fabric. The device has a simple structure, is easy to maintain, and has the advantages of flexible adjustment of pulling force, high efficiency, and good practicality.

[0004] Regarding the aforementioned disclosed patent content, two pressure rollers are provided to convey the fabric. However, the space between the two pressure rollers is narrow, making it difficult for workers to quickly pass the knitted fabric between the two pressure rollers. This may delay the progress of the knitted fabric traction work. At the same time, the distance between the two pressure rollers remains unchanged. When it is necessary to convey thicker knitted fabric, the fabric cannot pass through the gap between the two pressure rollers, thereby affecting the conveying effect of the fabric and reducing the adaptability of the pressure rollers. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a knitted fabric pulling mechanism to solve the technical problem of difficulty in adjusting the distance between two pressure rollers to adapt to knitted fabrics of different thicknesses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a knitted fabric pulling mechanism, comprising a base plate, a base fixed to the top of the base plate, and two mounting brackets mounted on the top of the base plate. A top plate is fixed to the top of each mounting bracket, and an adjustment assembly is provided between the top plate and the mounting brackets. The adjustment assembly includes two sliding grooves opened on the two mounting brackets, a sliding rod installed on one side of the mounting brackets, and a groove opened on the top of the top plate. A first lead screw is connected to the inside of the groove through a bearing, and a first threaded seat is sleeved on the outer wall of the first lead screw. A connecting plate is installed at the bottom of the first threaded seat. A sliding block is sleeved on the outer wall of the sliding rod. A slider is provided inside the sliding groove, and a push plate is rotatably connected between the slider and the sliding block. A pressure roller is rotatably connected between every two sliders.

[0007] By adopting the above technical solution, when the slider slides inside the groove, the slider will drive the pressure roller to move, so as to adjust the position of the pressure roller.

[0008] Furthermore, the bottom of the connecting plate is fixedly connected to the top of the slide, and one end of each pair of first lead screws extends to the outside of the top plate and is equipped with a rotating handle.

[0009] By adopting the above technical solution, it is convenient for workers to rotate the first lead screw through the handle, and the rotation of the first lead screw will drive the first threaded seat to rotate.

[0010] Furthermore, two second side plates are fixed on one side of the base, and each of the two second side plates is provided with a placement groove, and a feeding roller is placed between the two placement grooves.

[0011] By adopting the above technical solution, the placement groove is set up to place the feeding roller.

[0012] Furthermore, a first side plate is installed on the other side of the base, and a first motor is installed on the outer surface of the first side plate, with the output end of the first motor connected to a drive shaft.

[0013] By adopting the above technical solution, when the fabric needs to be rolled up, the staff can start the first motor, and the operation of the first motor can drive the drive shaft to rotate.

[0014] Furthermore, slots are provided at the top and bottom of the drive shaft, a take-up roller is sleeved on the outer wall of the drive shaft, and an insert that matches the slot is installed inside the take-up roller.

[0015] By adopting the above technical solution, when the drive shaft rotates, it will drive the take-up roller to rotate, and the take-up roller can take up the fabric after rotating.

[0016] Furthermore, damping pads are provided on both sides of the insert, and the damping pads are in close contact with the inner wall of the slot. The damping pads are made of rubber material.

[0017] By adopting the above technical solution, the damping pad improves the stability of the insert when it is inserted into the slot.

[0018] Furthermore, the base has an opening inside, and a second motor is installed below the opening. The output end of the second motor is connected to a second lead screw.

[0019] By adopting the above technical solution, when it is necessary to adjust the position of the traction roller, the operator can start the second motor, and the operation of the second motor can drive the second lead screw to rotate.

[0020] Furthermore, a second threaded seat is fitted on the outer wall of the second lead screw, and the top end of the second lead screw is connected to the port through a bearing.

[0021] By adopting the above technical solution, when the second lead screw rotates, it will drive the second threaded seat to move, and the movement of the second threaded seat will drive the second rotating plate to rotate.

[0022] Furthermore, a guide rod is installed inside the opening, and the guide rod passes through the second threaded seat.

[0023] By adopting the above technical solution, the guide rod can guide the second threaded seat, thereby improving the stability of the second threaded seat when it moves.

[0024] Furthermore, two first rotating plates are rotatably connected to both sides of the base, and a traction roller is rotatably connected between every two first rotating plates. A second rotating plate is rotatably connected between the first rotating plate and the second threaded seat.

[0025] By adopting the above technical solution, the first rotating plate can drive the traction roller to rotate, thereby facilitating the adjustment of the traction roller's position.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, by incorporating an adjustment component, allows the operator to rotate the first lead screw when the fabric needs to be passed between two pressure rollers. The rotation of the first lead screw moves the first threaded seat, which in turn moves the connecting plate, then the slide block, and finally the push plate. This causes the slider to slide within the groove, further rotating the pressure rollers and adjusting the gap between them. This increases the gap, allowing the operator to pass the fabric through. After passing the fabric, the operator reverses the rotation of the first lead screw, causing the first threaded seat to reset and move, which in turn moves the connecting plate and slide block back to their original positions. The push plate is then pulled to rotate, causing the slider to reset and move back to its original position. This causes the two pressure rollers to move towards each other and contact the fabric. This method allows the fabric to pass smoothly through the gap between the two pressure rollers. Furthermore, because the distance between the two pressure rollers is adjustable, it can accommodate knitted fabrics of different thicknesses, improving its applicability.

[0028] 2. This utility model has a sliding rod to guide the slide block, thereby improving the stability of the slide block when it moves; and a sliding groove to guide the slider, thereby improving the stability of the slider when it moves.

[0029] 3. This utility model is equipped with a handle, which makes it convenient for the operator to rotate the first lead screw. Since the outer surface and back of the first threaded seat are in contact with the inner wall of the groove, the first threaded seat can be guided, making it easy for the first threaded seat to move, and thus smoothly drive the connecting plate and the slide to move.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of this utility model will be described below based on its overall structure.

[0040] Example 1:

[0041] A knitted fabric tensioning mechanism, such as Figures 1-7 As shown, the system includes a base plate 1, a base 14 fixed to the top of the base plate 1, and two mounting brackets 24 mounted on the top of the base 14. A top plate 23 is fixed to the top of the mounting brackets 24, and an adjustment assembly 9 is provided between the top plate 23 and the mounting brackets 24. Two second side plates 11 are fixed to one side of the base 14, and each of the two second side plates 11 has a placement groove 12. A feeding roller 13 is placed between the two placement grooves 12. The placement grooves 12 are designed to place the feeding roller 13. A first side plate 2 is mounted on the other side of the base 14, and a first motor 3 is mounted on the outer surface of the first side plate 2. The output end of the first motor 3 is connected to a drive shaft 5. When the fabric needs to be wound up, the operator can start the first motor 3. The operation of the first motor 3 can drive the drive shaft 5 to rotate. A winding roller 6 is sleeved on the outer wall of the drive shaft 5. When the drive shaft 5 rotates, it will drive the winding roller 6 to rotate. After the winding roller 6 rotates, it can wind up the fabric.

[0042] See Figures 1-6The adjusting component 9 includes two sliding grooves 908 formed on two mounting brackets 24, a sliding rod 907 mounted on one side of the mounting bracket 24, and a groove 901 formed on the top of the top plate 23. The inside of the groove 901 is connected to a first lead screw 902 through a bearing, and the outer wall of the first lead screw 902 is fitted with a first threaded seat 903. A connecting plate 905 is installed at the bottom of the first threaded seat 903. The outer wall of the sliding rod 907 is fitted with a sliding block 906. A slider 910 is provided inside the sliding groove 908, and a push plate 909 is rotatably connected between the slider 910 and the sliding block 906. The outer surface and back of the first threaded seat 903 are in contact with the inner wall of the groove 901 to guide the first threaded seat 903. The sliding block 906 is slidably connected to the sliding rod 907 and can slide on the sliding rod 907.

[0043] Specifically, a pressure roller 4 is rotatably connected between every two sliders 910. The pressure roller 4 is slidably connected to the slide groove 908 through the slider 910. When the slider 910 slides inside the slide groove 908, the slider 910 will drive the pressure roller 4 to move so as to adjust the position of the pressure roller 4. The bottom of the connecting plate 905 is fixedly connected to the top of the slide block 906. One end of every two first lead screws 902 extends to the outside of the top plate 23 and is equipped with a handle 904, which makes it convenient for the operator to rotate the first lead screw 902 through the handle 904. The rotation of the first lead screw 902 will drive the first threaded seat 903 to rotate.

[0044] See Figures 1-5 The base 14 has an opening 15 inside, and a second motor 22 is installed below the opening 15. The output end of the second motor 22 is connected to a second lead screw 19. When the position of the pull roller 17 needs to be adjusted, the operator can start the second motor 22. The operation of the second motor 22 can drive the second lead screw 19 to rotate. The outer wall of the second lead screw 19 is fitted with a second threaded seat 21. The top end of the second lead screw 19 is connected to the opening 15 through a bearing. When the second lead screw 19 rotates, it will drive the second threaded seat 21 to move. The movement of the second threaded seat 21 will drive the second rotating plate 18 to rotate. Two first rotating plates 16 are rotatably connected to both sides of the base 14. A pull roller 17 is rotatably connected between every two first rotating plates 16. A second rotating plate 18 is rotatably connected between the first rotating plate 16 and the second threaded seat 21, so that when the first rotating plate 16 rotates, it can drive the pull roller 17 to rotate, thereby facilitating the adjustment of the position of the pull roller 17.

[0045] Example 2:

[0046] Based on the above embodiment 1, the following structure is provided to enable the disassembly of the take-up roller 6.

[0047] Specifically, slots 7 are provided at the top and bottom of the drive shaft 5, and inserts 8 that are compatible with the slots 7 are installed inside the take-up roller 6. Damping pads 10 are provided on both sides of the inserts 8. The damping pads 10 are tightly fitted to the inner wall of the slots 7. The damping pads 10 are made of rubber material. The setting of the damping pads 10 improves the stability of the inserts 8 when inserted into the slots 7, and at the same time allows the operator to remove the take-up roller 6 from the drive shaft 5 for disassembly.

[0048] Example 3:

[0049] Based on the above embodiment 1, in order to improve the stability of the second threaded seat 21 when it moves, it needs to be guided, so the following structure will be set.

[0050] See Figures 2-4 Inside the through-hole 15, a guide rod 20 is also installed. The guide rod 20 passes through the second threaded seat 21 and can guide the second threaded seat 21, thereby improving the stability of the second threaded seat 21 when it moves.

[0051] The working principle of this utility model is as follows: First, when using it, the operator can turn on the power supply, then place the feeding roller 13 between the two second side plates 11, then insert the insert 8 on the winding roller 6 into the slot 7, and push the winding roller 6 to move it so that the winding roller 6 can be fitted onto the drive shaft 5. The damping pad 10 improves the stability of the insert 8 inserted into the slot 7. Then, the operator can rotate the first lead screw 902 through the handle 904. The rotation of the first lead screw 902 will drive the first threaded seat 903 to move, which in turn drives the connecting plate 905 to move, which in turn drives the slide 906 to move, and drives the push plate 909 to rotate, which in turn drives the slider 910 to slide inside the slide groove 908, and then drives the pressure roller 4 to rotate, thereby Adjust the gap between the two pressure rollers 4 to increase the gap between them. Then, the operator pulls the fabric on the feed roller 13 so that the fabric passes through the right pull roller 17, then through the two pressure rollers 4, and then through the left pull roller 17 and is wound onto the take-up roller 6. Next, the operator rotates the first lead screw 902 in the opposite direction so that the first threaded seat 903 resets and moves, and then drives the connecting plate 905 and the slide 906 to reset and move. Then, the push plate 909 is pulled to rotate, and then the slider 910 resets and moves. Then, the two pressure rollers 4 move towards each other and come into contact with the fabric. Then, the first lead screw 902 is no longer rotated. Since the gap between the two pressure rollers 4 can be adjusted, it can adapt to knitted fabrics of different thicknesses, thus improving applicability.

[0052] When the fabric needs to be wound up, the first motor 3 can be started. The first motor 3 drives the drive shaft 5 to rotate, which in turn drives the take-up roller 6 to rotate. The take-up roller 6 then winds up the fabric, while the pull roller 17 pulls the fabric. When the position of the pull roller 17 needs to be adjusted to change the pulling force of the pull roller 17 on the fabric, the operator can start the second motor 22. The second motor 22 drives the second lead screw 19 to rotate, which in turn drives the second threaded seat 21 to move. The movement of the second threaded seat 21 pushes the second rotating plate 18 to rotate, which in turn pushes the pull roller 17 to rotate, so as to adjust the position of the pull roller 17. After the adjustment is completed, the second motor 22 can be turned off.
