Description

Technical Field

[0001] This utility model relates to the field of knitted fabric processing technology, and in particular to a correction device for knitted fabric processing. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarns into loops and interlocking them using knitting needles. It is divided into warp-knitted fabric and weft-knitted fabric. Knitted fabrics are soft, moisture-wicking, breathable, and warm. Most of them have excellent elasticity and extensibility. During the production and winding process of knitted fabric, a winding device is required, and a straightening device is needed to straighten the fabric during the winding process.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: When existing knitted fabric correction devices are used to correct the deviation, it is necessary to forcefully pull the misaligned fabric back to the correct position. This stretching will break the original balance of the fabric, resulting in curling edges and affecting the quality of the product. Summary of the Invention

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Reference Figures 1-6As shown, this utility model provides a technical solution: a correction device for knitted fabric processing, including a base 1: two supports 2 are provided at one end of the top of the base 1, and the opposing surfaces of the two supports 2 are rotatably connected to a feeding roller 3 via a rotating shaft. A through groove 4 is provided at the bottom of the support 2, and a transmission block 5 is fixed at the bottom of the support 2 and slidably connected to the through groove 4. A first threaded rod 6 is threadedly connected inside the transmission block 5. One end of the first threaded rod 6 is rotatably connected to one end inside the through groove 4. The other end of the first threaded rod 6 passes through the base 1 and is mounted on a motor 8. A boss 7 is installed at the bottom of the motor 8. The other end of the boss 7 is fixed to the base 1. A winding mechanism 11 is installed at the other end of the base 1. An mounting frame 12 is installed on the top of the base 1 near the winding mechanism 11. Guide shells 9 are provided on both sides of the support 2. The bottom of the guide shells 9 is fixed to the top of the base 1. Slider blocks 10 that are slidably connected to the guide shells 9 are fixed on both sides of both ends of the support 2.

[0027] The bottom of the mounting bracket 12 is provided with a curling and unfolding mechanism. The curling and unfolding mechanism includes through holes 13 at both ends of the top of the mounting bracket 12. Connecting rods 14 are slidably connected inside the two through holes 13. Flattening blocks 15 are fixed at the bottom of the two connecting rods 14. The two flattening blocks 15 are used together and are arranged in a V-shape. Control blocks 16 are fixed at the top of the two connecting rods 14.

[0028] The top of the mounting bracket 12 is provided with a height adjustment mechanism that works in conjunction with the edge curling mechanism;

[0029] The top of the control block 16 is equipped with a limiting component that works in conjunction with the height adjustment mechanism. The motor 8 drives the first threaded rod 6 to rotate. The first threaded rod 6 is threadedly connected to the transmission block 5, causing the transmission block 5 to drive the bracket 2 to shift left and right, correcting the deviation of the fabric. When the bracket 2 moves, the sliding connection between the slider 10 and the guide shell 9 prevents the bracket 2 from shifting. During the correction process, the figure-eight structure formed by the two flattening blocks 15 continuously contacts the moving edge of the knitted fabric, decomposing the longitudinal moving force of the fabric into a lateral expansion force. At the same time, the elasticity of the knitted fabric is used to forcibly unfold the curled edge of the fabric. The height of the flattening block 15 can be adjusted by the height adjustment mechanism, thereby adjusting the pressing force. The limiting component limits the height adjustment mechanism to prevent it from moving on its own.

[0030] Reference Figure 2 and Figure 5As shown in this embodiment: the height adjustment mechanism includes a circular groove 17 formed on the top of the mounting bracket 12. A rotating block 18 is rotatably connected inside the circular groove 17. A second threaded rod 19 is fixed to the top of the rotating block 18. The top end of the second threaded rod 19 passes through the control block 16 and is fixed to a control disk 20. The second threaded rod 19 is threadedly connected to the control block 16. A hollow limiting ring 25 that cooperates with the rotating block 18 is fixed to the top end inside the circular groove 17. Through the threaded connection between the second threaded rod 19 and the control block 16, when the user controls the rotation of the second threaded rod 19 through the control disk 20, the control block 16 will move, thereby adjusting the height of the flattening block 15. The hollow limiting ring 25 limits the rotation block 18, preventing the rotation block 18 from moving up and down significantly inside the circular groove 17.

[0031] Reference Figure 4 As shown in this embodiment: the limiting component includes an L-shaped movable block 26 slidably connected to the top of the control block 16. Guide grooves 27 are provided on both sides of the top of the L-shaped movable block 26. A limiting rod 28 is slidably connected inside the guide groove 27. A limiting block 29 is fixed to the top of the limiting rod 28. A slot 30 is provided at one end of the L-shaped movable block 26 near the second threaded rod 19. After the flattening block 15 is adjusted to the correct height by the height adjustment mechanism, the slot 30 is engaged with the second threaded rod 19 by controlling the L-shaped movable block 26, thereby locking the second threaded rod 19 and preventing it from rotating. The limiting rod 28 and the guide groove 27 can limit the L-shaped movable block 26 and prevent it from shifting or rotating during use.

[0032] Reference Figure 3 As shown in this embodiment: both ends of the flattening block 15 are provided with first rounded corners 21, and the bottom corners of the flattening block 15 are provided with second rounded corners 22. By setting the first rounded corners 21 and the second rounded corners 22, the flattening block 15 can guide the fabric more smoothly, while avoiding tearing the fabric.

[0033] Reference Figure 3 As shown in this embodiment: the bottom of the flattening block 15 is provided with a first mounting groove 23, and a number of first rollers 24 are rotatably connected inside the first mounting groove 23 via a rotating shaft. By setting the first rollers 24, the friction between the flattening block 15 and the fabric can be reduced, and the fabric temperature can be avoided due to strong friction.

[0034] Reference Figure 4As shown in this embodiment: a spring 32 is fixed to one end of the L-shaped movable block 26 away from the second threaded rod 19, and a protruding plate 31 is fixed to the other end of the spring 32. The bottom of the protruding plate 31 is fixed to the top of the L-shaped movable block 26, and the distance between the protruding plate 31 and the L-shaped movable block 26 is greater than or equal to the length of the guide groove 27. The spring 32 is used to limit the L-shaped movable block 26 and prevent the L-shaped movable block 26 from moving on its own when it is engaged with the second threaded rod 19 in the slot 30.

[0035] Reference Figure 6 As shown in this embodiment: a second mounting groove 33 is provided at the bottom of the slider 10, and a second roller 34 is rotatably connected inside the second mounting groove 33 via a rotating shaft. The setting of the second roller 34 reduces the friction between the slider 10 and the guide shell 9, thereby making the support 2 move more smoothly and avoiding jamming.

[0036] Working Principle: The motor 8 drives the first threaded rod 6 to rotate. The threaded connection between the first threaded rod 6 and the transmission block 5 causes the transmission block 5 to move the bracket 2 left and right. This corrects misaligned fabric. During the movement of the bracket 2, the sliding connection between the slider 10 and the guide shell 9 prevents misalignment. During the correction process, the figure-eight structure formed by two flattening blocks 15 continuously contacts the moving edge of the knitted fabric, decomposing the longitudinal force of the fabric into a lateral expansion force. Simultaneously, the elasticity of the knitted fabric is utilized to forcibly unfold the curled edge. The height of the flattening blocks 15 can be adjusted via a height adjustment mechanism, thereby adjusting the clamping force. A limit component limits the height adjustment mechanism to prevent it from moving on its own. The second threaded rod 19 is threadedly connected to the control block 16, allowing the user to control the device via a control panel. When the second threaded rod 19 is rotated, the control block 16 moves, thereby adjusting the height of the flattening block 15. The hollow limit ring 25 limits the rotation block 18, preventing the rotation block 18 from moving up and down significantly inside the circular groove 17. After the flattening block 15 is adjusted to the correct height by the height adjustment mechanism, the L-shaped movable block 26 is controlled to engage the slot 30 with the second threaded rod 19, thereby locking the second threaded rod 19 and preventing it from rotating. The limit rod 28 and the guide groove 27 limit the L-shaped movable block 26, preventing it from shifting or rotating during use.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
