Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to a straightening device for knitted fabrics used in textile factories. Background Technology

[0002] In the field of knitted fabric production and processing, fabric straightening and setting is a crucial step in ensuring the quality of subsequent cutting, sewing, and other processes. Its core requirement lies in precisely controlling tension and pressure based on the thickness, elasticity, and other characteristics of different knitted fabrics, while minimizing damage to the fabric fibers to ensure fabric flatness and integrity, thereby reducing the defect rate. However, current mainstream knitted fabric straightening and setting equipment still faces some challenges in practical applications, making it difficult to meet diverse production needs and high-quality processing standards.

[0003] In terms of fabric adaptability, traditional straightening equipment mostly uses a fixed roller design, and the roller angle cannot be flexibly adjusted according to the fabric characteristics. For thin, low-elasticity knitted fabrics, the fixed-angle roller is prone to generating excessive tension, leading to problems such as stretching damage and edge wrinkling. On the other hand, for thick, high-elasticity knitted fabrics, insufficient tension makes it difficult to achieve complete straightening, which can easily cause dimensional deviations in subsequent processing and seriously affect product consistency.

[0004] In terms of fabric damage control, existing equipment generally lacks effective cushioning design in its compaction mechanisms. Most equipment relies on rigid components directly contacting the fabric for compaction and shaping. During the compaction process, rigid impacts can easily damage the fiber structure of knitted fabrics, leading to defects such as indentations and fiber breakage on the fabric surface. This not only affects the appearance quality of the fabric but also reduces its durability, significantly increasing the defect rate. Therefore, a device is needed that can precisely adjust the angle of the pull rollers, effectively cushion the compaction impact, and conveniently adjust the compaction force. Utility Model Content

[0029] The present invention will be further described in detail below with reference to embodiments:

[0030] Example 1

[0031] like Figure 1-7 As shown in the figure, an embodiment of the present invention provides a knitted fabric straightening device for textile factories, comprising: a base plate 1, on which symmetrically distributed first side plates 2, second side plates 3, and baffles 4 are fixedly connected; connecting rods 5 are rotatably connected to the exterior of each of the two first side plates 2, and pull rollers 6 are rotatably connected to the side surfaces of the connecting rods 5; a rotating seat 7 is fixedly connected to the side surface of the first side plates 2, and an electric push rod 8 is rotatably connected to the exterior of the rotating seat 7; a movable block 9 is fixedly connected to the output end of the electric push rod 8, and the exterior of the movable block 9 is connected to... The connecting rod 5 is rotatably connected; the upper surface of the base plate 1 is fixedly connected to the telescopic column 10, which includes an overlapping block 101 and a first spring 102. The lower surface of the overlapping block 101 is fixedly connected to the first spring 102, and the bottom end of the first spring 102 is fixedly connected to the base plate 1. The top end of the telescopic column 10 is rotatably connected to an L-shaped crossbar 11, and the outside of the L-shaped crossbar 11 is rotatably connected to a U-shaped plate 12. A sleeve block 13 is fixedly connected to the U-shaped plate 12, and pressure blocks 14 of different weights can be placed on the sleeve block 13.

[0032] The telescopic column 10 has a locking screw 15 internally threaded, and a protrusion 151 is fixedly connected to the outside of the locking screw 15. The outside of the protrusion 151 abuts against the L-shaped crossbar 11 during use. The baffle 4 has a limiting groove 401 internally, and a slider 16 is slidably connected inside the limiting groove 401. A second spring 17 is fixedly connected to the upper surface of the slider 16, and the top of the second spring 17 is fixedly connected to the U-shaped plate 12. A silicone pad 18 is fixedly connected to the lower surface of the U-shaped plate 12. An elastic pad 19 is fixedly connected to the upper surface of the base plate 1, and the elastic pad 19 is located below the U-shaped plate 12. Two... A take-up drum 20 is rotatably connected between the two side plates 3, and a slot 2001 is provided on the outside of the take-up drum 20; a motor 21 is fixedly connected to the outside of the second side plate 3, and the output end of the motor 21 is fixedly connected to the take-up drum 20; a guide roller 22 is rotatably connected between the two first side plates 2, and the guide roller 22 is located on the side of the elastic pad 19; a pressure sensor 23 is provided on the outside of the pull roller 6, and the pressure sensor 23 is electrically connected to the electric push rod 8; four symmetrically distributed support columns 24 are fixedly connected to the lower surface of the base plate 1; an upper pressure roller 201 and a lower pressure roller 202 are rotatably connected between the two first side plates 2.

[0033] In this embodiment, the fabric is first passed through the pull roller 6, so that the end of the fabric is inserted into the slot 2001 of the take-up drum 20. Then, the motor 21 is started to drive the take-up drum 20 to rotate, so that the fabric is wound around the outside of the take-up drum 20. During the winding process, the fabric is guided by the guide roller 22 and then initially flattened by the upper pressure roller 201 and the lower pressure roller 202, which can remove slight wrinkles. When it is necessary to straighten the fabric, the electric push rod 8 adjusts the angle of the pull roller 6 by pushing the connecting rod 5, thereby changing the fabric tension. At the same time, the pressure sensor 23 on the pull roller 6 detects the pressure in real time, forming a closed-loop control with the electric push rod 8 to avoid excessive or insufficient tension and ensure the straightening effect. During the conveying process, the U-shaped plate 12 uses the gravity of the pressure block 14 to compress the fabric through the silicone pad 18. The first spring 102 of the telescopic column 10 and the second spring 17 of the baffle 4 provide buffering to adapt to the fluctuation of the fabric thickness. In addition, the position of the U-shaped plate 12 can be adjusted by the locking screw 15, thereby further enhancing the shaping effect.

[0034] Example 2

[0035] like Figure 1-7As shown in the figure, this utility model provides a knitted fabric straightening device for textile factories, which includes a base plate 1. A first side plate 2, a second side plate 3, and a baffle 4 are symmetrically connected to the upper surface of the base plate 1. First, the knitted fabric to be straightened is passed sequentially through a pull roller 6, an upper pressure roller 201, and a lower pressure roller 202, causing the fabric end to be engaged in the slot 2001 of a take-up drum 20. Then, a motor 21 is started to rotate the take-up drum 20, causing the fabric to be evenly wound around the outside of the take-up drum 20. The fabric passes through a guide roller 22 at the feed end of the device, which provides a stable conveying direction for the fabric, ensuring that the fabric enters the straightening structure along a preset path. After passing through the pull roller 6, the fabric enters between the upper pressure roller 201 and the lower pressure roller 202. The two rollers are pressed together by a preset pressure, and under the squeezing action of the two rollers, slight wrinkles on the surface of the fabric are removed, completing the initial flattening and laying the foundation for subsequent precise straightening.

[0036] When fabric tension adjustment is required, the electric push rod 8 is activated to move the connecting rod 5, thereby enabling the pull roller 6 to dynamically adjust the fabric tension and ensure uniform and controllable straightening. Specifically, the rotating seat 7 of the first side plate 2 provides a fixed rotation fulcrum for the electric push rod 8. The output end of the electric push rod 8 is rotatably connected to the movable block 9 on the connecting rod 5, allowing the electric push rod 8 to move the pull roller 6 through its telescopic movement, thus changing the angle of the pull roller 6. When the electric push rod 8 pushes the connecting rod 5, the tension increases; when the electric push rod 8 pulls the connecting rod 5 back, the tension decreases, thereby achieving adaptive adjustment for knitted fabrics of different thicknesses and elasticities.

[0037] It should be noted that the pressure sensor 23 mounted externally on the pull roller 6 is electrically connected to the electric push rod 8, forming a closed-loop control system. The pressure sensor 23 detects the contact pressure between the pull roller 6 and the fabric in real time and transmits the signal to the control unit of the electric push rod 8. If the tension is too high, the control unit will instruct the electric push rod 8 to shorten appropriately, reducing the pressure on the pull roller 6. If the tension is too low, the control unit will instruct the electric push rod 8 to extend, increasing the pressure on the pull roller 6, thus preventing the fabric from being incompletely straightened due to insufficient tension, or from being stretched, deformed, or damaged due to excessive tension.

[0038] After the fabric is straightened by the roller 6, it is further compacted and shaped by the cooperation of the U-shaped plate 12 and the elastic pad 19, and the elastic structure prevents damage to the fabric. At the same time, the socket block 13 on the U-shaped plate 12 can hold pressure blocks 14 of different weights. According to the thickness of the fabric and the shaping requirements, a pressure block 14 of appropriate weight is selected. The weight of the pressure block 14 is used to make the silicone pad 18 on the lower surface of the U-shaped plate 12 fit tightly against the fabric surface. The silicone pad 18 is soft, which can increase the contact area with the fabric, ensure uniform compaction, and avoid scratching the fabric surface by hard contact.

[0039] The elastic pad 19 on the upper surface of the base plate 1 is located directly below the U-shaped plate 12, forming an upper-pressing and lower-supporting fit with the silicone pad 18 of the U-shaped plate 12. The elastic pad 19 can deform slightly according to the thickness of the fabric, providing flexible support for the fabric and preventing the bottom of the fabric from directly contacting the hard base plate 1 and causing wear. At the same time, it enhances the compaction effect in the vertical direction, ensuring that the fabric is not prone to springback after being shaped. After being straightened, compacted and shaped, the fabric is finally automatically wound up by the winding drum 20, realizing continuous production.

[0040] Example 3

[0041] like Figure 1-7 As shown in the figure, this utility model discloses a knitted fabric straightening device for textile factories, which includes a base. A telescopic column 10 is fixedly connected to the upper surface of the base plate 1. The telescopic column 10 consists of an overlap block 101 and a first spring 102. The bottom end of the first spring 102 is fixed to the base plate 1, and its top end is connected to the overlap block 101. When the U-shaped plate 12 applies pressure to the fabric, the first spring 102 can absorb part of the pressure impact through elastic deformation, avoiding excessive pressure that could cause fabric deformation. At the same time, if there are slight thickness fluctuations on the fabric surface, the extension and contraction of the first spring 102 can drive the U-shaped plate 12 to adjust slightly up and down, ensuring that the silicone pad 18 is always in contact with the fabric, thus making the compaction effect stable.

[0042] In addition, the limiting groove 401 inside the baffle 4 restricts the sliding direction of the slider 16, and the top of the second spring 17 on the upper surface of the slider 16 is fixedly connected to the U-shaped plate 12. Firstly, it can provide vertical support for the U-shaped plate 12, preventing the U-shaped plate 12 from tilting due to uneven force. Secondly, the elasticity of the second spring 17 can work in conjunction with the first spring 102 of the telescopic column 10 to further enhance the buffering capacity of the U-shaped plate 12 and ensure a smooth compaction process.

[0043] Once the height and pressure of the U-shaped plate 12 are adjusted to the appropriate levels, rotate the locking screw 15 inside the telescopic column 10, causing the external protrusion 151 to abut against the L-shaped crossbar 11. At this point, the position of the L-shaped crossbar 11 is fixed, thereby locking the height and compaction pressure of the U-shaped plate 12 and preventing parameter deviations due to vibration during continuous operation.
