Description

Technical Field

[0001] This invention relates to the field of fabric conveying technology, specifically to a baby cotton fabric anti-deviation traction device. Background Technology

[0002] As essential clothing items for daily life, softness, delicacy, close fit, and warmth are often important factors for consumers when choosing clothing. However, with the continuous improvement of people's living standards, the requirements for the mildew-proof and antibacterial properties of clothing are also increasing. Children, as a more active group, often get their clothes stained due to playing and roughhousing. Parents often consider the stain resistance and antibacterial ability of children's clothing. Therefore, the demand for skin-friendly, moisture-wicking, warm, and highly antibacterial children's clothing fabrics is growing.

[0003] Children's clothing fabrics are prepared using a three-layer composite fabric consisting of an outer fabric, an inner lining, and a close-fitting inner layer. The outer layer of this fabric provides antibacterial and bacteriostatic properties, the inner lining provides warmth, and the close-fitting inner layer is skin-friendly and moisture-wicking. For example, Chinese Patent CN202110209155.6 discloses an antibacterial children's clothing fabric, its processing method, and its application. This solution cleverly uses a blend of antibacterial and moisture-wicking yarns to create the inner lining, while the close-fitting fabric layer is woven from cotton yarn. The outer fabric layer uses ultra-fine denier yarn to improve moisture-wicking and heat dissipation capabilities. The fabric is then used to make the garment. Finally, the inner fabric layer uses cotton yarn to increase its skin-friendliness and absorb sweat from the body. The lining layer, made with moisture-wicking yarn, further improves the evaporation of sweat absorbed in the inner fabric layer, accelerating the drying speed and allowing the wearer to maintain a better wearing experience. In addition, the outer fabric layer is treated with antistatic agents to prevent the adsorption of a large number of particles on the fabric surface, further preventing bacterial growth and resulting in better wearing experience and effect for children's clothing.

[0004] In the fabric manufacturing process of children's clothing, when bonding the inner lining layer to the inner fabric layer and the outer fabric layer to the inner lining layer, the layers need to be sewn together and fixed according to a preset trajectory. During the transport of the fabric layers, a corresponding fabric conveying roller assembly is required to pull and bond the multiple layers of fabric before sewing. However, existing children's clothing fabrics are prone to fabric misalignment during transport, and cannot be corrected in time, resulting in wrinkles in the fabric layers and preventing them from being aligned and smoothly bonded together, thus affecting the fabric processing progress and efficiency.

[0005] Therefore, we propose a baby cotton fabric anti-deviation and traction device to solve the above problems. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides a baby cotton fabric anti-deviation pulling device, which solves the problem that existing children's clothing fabric layers are prone to fabric deviation during the conveying process, and cannot be corrected and adjusted in time, resulting in wrinkles in the fabric layers and the inability to align and flatten the layers, thus affecting the fabric processing process and efficiency.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0010] A baby cotton fabric anti-deviation pulling device includes at least two sets of anti-deviation pulling roller groups. Each anti-deviation pulling roller group includes a measuring roller and a correction roller. The measuring roller is used to measure the fabric deviation while pulling the fabric. The measuring roller includes a first roller shaft and a first roller body disposed on the first roller shaft. The first roller body is provided with a first traction groove. On the left and right sides of the groove surface corresponding to the first traction groove, a first deviation measuring unit, a second deviation measuring unit, and a third deviation measuring unit are arranged sequentially from the inside to the outside. The correction roller is used to correct the fabric deviation in the opposite direction. The correction roller includes a second roller shaft, a second roller body, and a correction device. The correction device is disposed on the second roller shaft, and the second roller body is mounted on the correction device. The second roller body is provided with a second traction groove. The correction device is used to drive the second roller body to slide laterally along the surface of the second roller shaft, so that the pulled and deviated fabric moves laterally in the opposite direction of the fabric deviation, thereby correcting the deviated fabric.

[0011] Furthermore, the baby cotton fabric anti-deviation pulling device also includes a PLC controller, which is electrically connected to the first deviation measuring unit, the second deviation measuring unit, the third deviation measuring unit, and the actuator of the correction device.

[0012] Furthermore, several anti-deviation traction roller groups are arranged side by side, with the correction roller located to the upper right of the measuring roller.

[0013] Furthermore, the first offset measuring unit, the second offset measuring unit, and the third offset measuring unit all include a measuring ring plate sleeved on the first roller and a pressure-sensing element arranged circumferentially on the surface of the measuring ring plate, and the width of each measuring ring plate is the same.

[0014] Furthermore, the distance L1 between two adjacent first offset measuring units on the first roller is adapted to the width W1 of the fabric to be pulled, and the groove width W2 of the second traction groove is equal to L1.

[0015] Furthermore, the correction device includes a correction motor, a trapezoidal lead screw, and a lead screw and nut assembly. The correction motor is fixedly mounted on one end of the second roller shaft via a base. A lead screw connecting seat is provided on the other end of the second roller shaft. One end of the trapezoidal lead screw is rotatably connected to the lead screw connecting seat, and the other end of the trapezoidal lead screw is connected to the output shaft of the correction motor. The second roller body is connected to the trapezoidal lead screw via the lead screw and nut assembly. The second roller body is coaxially arranged with the second roller shaft. A slider is connected to the inner ring of the lead screw and nut assembly. A sliding groove is provided on the second roller shaft to slide with the slider. The sliding groove is parallel to the trapezoidal lead screw.

[0016] Furthermore, the front and rear ends of the second roller body are connected to the second roller shaft through a support structure. The support structure includes a support block, which is mounted on the second roller shaft through a sliding bearing. The front and rear ends of the second roller body are stably supported by the support block, and the support block is provided with a through hole adapted to the trapezoidal lead screw.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a baby cotton fabric anti-deviation and traction device, which has the following beneficial effects:

[0019] 1. This invention, by pre-setting at least two sets of anti-deviation traction rollers, uses the first set of anti-deviation traction rollers to detect and correct fabric deviation, and the second set of anti-deviation traction rollers to perform secondary detection and correction. This allows for timely detection and adjustment of fabric deviation, ensuring that the pulled fabric travels entirely along the predetermined traction path, preventing wrinkles from forming during the conveying process, and avoiding impact on the processing progress and efficiency of children's clothing fabrics.

[0020] 2. This invention designs a measuring roller with three lateral offset pressure sensing areas and a correction roller with a correction device to form an anti-offset traction roller group. It can monitor the fabric offset in real time and make targeted reverse offset correction adjustments based on the offset direction of the pulled fabric, so that the pulled fabric returns to the predetermined traction path. The highly reasonable offset measurement and correction method achieves high-precision and high-reliability fabric correction. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example

[0029] like Figures 1-5 As shown, an embodiment of the present invention provides a baby cotton fabric anti-deviation pulling device, comprising at least two sets of anti-deviation pulling roller groups. Each anti-deviation pulling roller group includes a measuring roller 1 and a correction roller 2. The measuring roller 1 is used to measure the fabric deviation while pulling the fabric, and the correction roller 2 is used to correct the fabric deviation in the opposite direction. The present invention adds multiple sets of anti-deviation pulling roller groups. Taking two sets as an example, the first set of anti-deviation pulling roller groups can perform a first correction on the deviated fabric. When the measuring roller 1 in the first set of anti-deviation pulling roller groups detects that the pulled fabric has deviated, the correction roller 2 corrects the pulled fabric. The measuring roller 1 in the second set of anti-deviation pulling roller groups can play a secondary detection role. The secondary detection determines whether the pulled fabric has been sufficiently corrected. If the pulled fabric is not fully and completely centered after the secondary detection, the correction roller 2 in the second set of anti-deviation pulling roller groups performs a second correction, adjusting in time to avoid the fabric deviation during the pulling process, ensuring that the pulled fabric travels completely along the predetermined pulling path, and preventing wrinkles from forming in the fabric during the conveying process.

[0030] Measuring roller 1 includes a first roller shaft 101 and a first roller body 102 disposed on the first roller shaft 101. The first roller body 102 is provided with a first traction groove 1021. On the left and right sides of the groove surface corresponding to the first traction groove 1021, a first offset measuring unit 103, a second offset measuring unit 104, and a third offset measuring unit 105 are arranged sequentially from the inside to the outside, forming three offset degrees. Correcting roller 2 is used to correct the fabric in the opposite direction of the fabric offset. Correcting roller 2 includes a second roller shaft 201, a second roller body 202, and a correction device 203. 03 is mounted on the second roller shaft 201, and the second roller body 202 is mounted on the correction device 203. The second roller body 202 is provided with a second traction groove 2021. During operation, the correction device 203 drives the second roller body 202 to slide laterally along the surface of the second roller shaft 201, so that the pulled fabric that has deviated moves laterally in the opposite direction of the fabric deviation, thereby correcting the deviation of the fabric. When the pulled fabric deviates by one degree, the correction device 203 drives the pulled fabric that has deviated to move laterally by one degree in the opposite direction of the fabric deviation; when the pulled fabric deviates by two degrees, the correction device 203 drives the pulled fabric that has deviated to move laterally by two degrees in the opposite direction of the fabric deviation, and so on.

[0031] The present invention also includes a PLC controller electrically connected to the drive motors of the first roller shaft 101, the second roller shaft 201, the first offset measuring unit 103, the second offset measuring unit 104, the third offset measuring unit 105, and the actuator of the correction device 203. The PLC controller receives measurement signals from the first offset measuring unit 103, the second offset measuring unit 104, and the third offset measuring unit 105 in real time. When the first offset measuring unit 103 detects that the traction fabric is covered on its surface, it indicates that the traction fabric has shifted by a length less than or equal to the width of the first offset measuring unit 103. When both the first offset measuring unit 103 and the second offset measuring unit 104 detect the traction fabric, it indicates that the traction fabric has shifted by a length less than or equal to the width of the first offset measuring unit 105. 3. The length of the sum of the widths of the first offset measuring unit 103 and the second offset measuring unit 104 is greater than the width of the first offset measuring unit 103; when the first offset measuring unit 103, the second offset measuring unit 104 and the third offset measuring unit 105 all detect the traction fabric, it indicates that the traction fabric has shifted by a length less than or equal to the sum of the widths of the first offset measuring unit 103, the second offset measuring unit 104 and the third offset measuring unit 105 and greater than the sum of the widths of the first offset measuring unit 103 and the second offset measuring unit 104; based on the detected traction fabric shift, the PLC controller controls the actuator of the correction device 203 to drive the second roller body 202 to move laterally along the second roller shaft 201 in the opposite direction of the fabric shift by the corresponding shift, so that the traction fabric returns to the predetermined traction path, thus completing the correction operation for the shifted fabric.

[0032] like Figure 1 and Figure 5 As shown, in some embodiments, several anti-deviation traction roller groups are arranged side by side. In each anti-deviation traction roller group, the correction roller 2 is located at the upper right position of the measuring roller 1. The fabric being pulled is pulled from the upper left of the measuring roller 1 to the top position of the measuring roller 1, and then pulled by the previous anti-deviation traction roller group to the bottom position of the next measuring roller 1. During the fabric conveying process, the measuring roller 1 detects whether the pulled fabric has deviated, and the correction roller 2 corrects the fabric deviation after the pulled fabric deviates.

[0033] like Figure 2As shown, in some embodiments, the first offset measuring unit 103, the second offset measuring unit 104, and the third offset measuring unit 105 all include a measuring ring plate sleeved on the first roller body 102 and pressure-sensing elements arranged circumferentially on the surface of the measuring ring plate. The pressure-sensing elements are one of the HBM series load cells. Each HBM load cell is circumferentially distributed on the surface of the measuring ring plate. When the first roller shaft 101 drives the first roller body 102 to rotate, and the HBM load cell detects the traction fabric load, it transmits the detected electrical signal to the PLC controller. The PLC controller controls the correction device 203 to drive the traction fabric that has shifted laterally in the opposite direction of the fabric shift by a corresponding offset degree. It should be noted that the width of each measuring ring plate is the same, thus forming three offset degrees.

[0034] In some embodiments, the distance L1 between two adjacent first offset measuring units 103 on the first roller body 102 is adapted to the width W1 of the fabric to be pulled. The distance L1 between two adjacent first offset measuring units 103 is preferably slightly larger than the width W1 of the pulled fabric, and the extra space in L1 is an acceptable offset of the pulled fabric. In order to ensure that the correction roller 2 is adapted to the measuring roller 1, the groove width W2 of the second traction groove 2021 is equal to L1.

[0035] like Figure 3 and Figure 4As shown, in some embodiments, the correction device 203 includes a correction motor 2031, a trapezoidal lead screw 2032, and a lead screw nut pair 2033. The correction motor 2031 is fixedly mounted on one end of the second roller shaft 201 via a base 2034. A lead screw connecting seat 2035 is provided on the other end of the second roller shaft 201. One end of the trapezoidal lead screw 2032 is rotatably connected to the lead screw connecting seat 2035, and the other end of the trapezoidal lead screw 2032 is connected to the output shaft of the correction motor 2031. The second roller body 202 is connected to the trapezoidal lead screw 2032 via the lead screw nut pair 2033. The second roller body 202 is coaxially arranged with the second roller shaft 201. A slider 2036 is connected to the inner ring of the lead screw nut pair 2033. A groove 2011 is provided on the second roller shaft 201 that slides with the slider 2036. The groove 2011 is parallel to the trapezoidal lead screw 2032. (Measuring roller...) 1. Upon detecting a deviation in the pulled fabric, the information is promptly sent to the PLC controller. Based on the detected deviation, the PLC controller controls the correction motor 2031 to operate. The output shaft of the correction motor 2031 drives the trapezoidal lead screw 2032 to rotate. Since the lead screw nut pair 2033 slides in conjunction with the slide groove 2011 on the second roller shaft 201 through the slider 2036, the lead screw nut pair 2033 converts the rotational motion into linear motion on the second roller shaft 201 during the rotation of the trapezoidal lead screw 2032. Through the lead screw nut pair 2033, the second roller body 202 is moved laterally by the corresponding deviation distance in the opposite direction of the fabric deviation, gradually pulling the pulled fabric back to the correct track. After the first set of anti-deviation pulling rollers completes the correction, the second set of anti-deviation pulling rollers performs correction detection and performs secondary correction before the pulled fabric is completely corrected.

[0036] like Figure 4 As shown, in some embodiments, the front and rear ends of the second roller body 202 are connected to the second roller shaft 201 through a support structure 204. The support structure 204 can provide balanced support for the front and rear ends of the second roller body 202, avoid stress concentration on the roller shaft, and increase the stability of the second roller body 202. The support structure 204 includes a support block 2041, which is mounted on the second roller shaft 201 through a sliding bearing 2042. The sliding bearing 2042 can reduce the friction between the support structure 204 and the roller shaft during the lateral movement of the second roller body 202. In order to prevent the support block 2041 from contacting the trapezoidal lead screw 2032, a through hole adapted to the trapezoidal lead screw 2032 is provided on the support block 2041.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
