Description

Technical Field

[0001] This utility model relates to the field of blended yarn processing technology, specifically to an automated blended yarn bleaching device. Background Technology

[0002] Blended yarn is a composite yarn made by mixing two or more different fibers (such as cotton, polyester, wool, linen, etc.) through a spinning process. Its core advantage lies in the combination of the characteristics of different fibers, such as the moisture absorption of cotton, the strength of polyester, and the warmth of wool, to form a yarn product with excellent comprehensive performance. Blended yarn is widely used in clothing, home textiles, industrial textiles and other fields.

[0003] During production, bleaching removes natural pigments, impurities, and stains from fibers, resulting in pure white yarn that meets the requirements for subsequent dyeing or direct use. However, one factor contributing to the low yield rate of blended yarns during bleaching is tension control. Due to the significant differences in elastic modulus and elongation of different fibers, uneven tension can cause some areas of fibers to become excessively loose, leading to excessive bleach penetration, resulting in fiber damage and reduced strength. Alternatively, it can cause some areas of fibers to become too tight, resulting in insufficient bleach penetration, color differences, and uneven whiteness, thus affecting the quality of the finished product.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide an automated blended yarn bleaching device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides an automated blended yarn bleaching device, comprising a housing, a scissor frame, and a tension roller. The scissor frame is vertically slidably mounted on the side wall of the housing along its length. The housing has an adjustment mechanism and a drive mechanism inside the side wall corresponding to the scissor frame. The adjustment mechanism includes: Multiple fixed blocks are rotatably connected to the middle of one side wall of the scissor lift away from the center of the box and are located on the same horizontal line. The top of the side wall of the multiple fixed blocks that are close to each other is horizontally rotatably connected to the same lead screw. The driving mechanism includes a motor fixed to the side wall of the fixed block located in the middle away from the scissor lift. The drive wheel is rotatably mounted on the bottom of the side wall of the fixed block away from the scissor lift. Tensioning wheels are rotatably mounted at multiple rotating connection points on the bottom side of the scissor lift away from the inside of the housing. The same drive belt is fitted into the groove of the tensioning wheel and the two adjacent drive wheels.

[0007] Furthermore, the tension roller is rotatably connected to the side wall of the scissor lift away from the fixed block, corresponding to the positions of the drive wheel and the tension wheel respectively. A connecting shaft is coaxially fixed to the side wall of the tension roller near the scissor lift. The end of the connecting shaft away from the tension roller rotatably passes through the scissor lift and is fixed to the corresponding drive wheel or tension wheel. Multiple partition rings are fixed on the outer arc wall of the tension roller. The multiple partition rings are linearly and equally spaced along the axial direction of the tension roller. A spline sleeve is coaxially fixed on the outside of the motor output shaft. A sleeve shaft one is coaxially provided on the outside of the spline sleeve away from the motor. A sleeve shaft two is rotatably provided on the inner arc wall of sleeve shaft one. A drive gear is coaxially fixed on the outer arc wall of sleeve shaft one. A bevel gear is fixed on the end of sleeve shaft two away from the motor. A sleeve shaft three is coaxially slidably sleeved on the outside of the spline sleeve. The end of sleeve shaft three away from the motor is movably inserted into sleeve shaft one.

[0008] Furthermore, the inner arc wall of the first sleeve shaft has multiple grooves arranged in a circular array along its axial direction at the end near the motor. The inner arc wall of the second sleeve shaft has multiple grooves arranged in a circular array along its axial direction at the end near the motor. Grooves 1 and 2 are not located on the same vertical plane, and groove 1 is closer to the motor. Multiple limiting blocks arranged in a circular array along its axial direction are movably disposed on the outer arc wall of the third sleeve shaft. Grooves 3 are formed on the outer arc wall of the third sleeve shaft at the positions corresponding to the limiting blocks. A return spring is fixed to the end of the limiting block near the inner wall of groove 3. The end of the return spring away from the limiting block is fixed to the inner wall of groove 3. Both sides of the end of the limiting block away from the outer arc wall of the third sleeve shaft are rounded along the axial direction of the third sleeve shaft.

[0009] Furthermore, a fixed plate is coaxially fixed to one end of the sleeve shaft near the motor. A limiting clamp is sleeved on the outer edge of the fixed plate. An electric push rod is fixed to the horizontal side of the limiting clamp near the motor. The electric push rod is fixed to the top of the motor. The limiting clamp has a "door" shaped cross section along the radial direction of the fixed plate, with the notch facing the fixed plate. A transmission gear with the same structure meshes with the side of the transmission gear near the lead screw. The transmission gear located away from the motor is coaxially fixed to the outer arc wall of the lead screw. A vertical annular gear is meshed with the side of the bevel gear away from the lead screw. An internal gear ring is coaxially fixed to the inner arc wall of the annular gear ring. A horizontal linkage gear meshes with the bottom end of the inner arc wall of the internal gear ring. The end of the linkage gear near the scissor lift is coaxially fixed to the corresponding transmission wheel.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The drive mechanism drives the adjustment mechanism, and the screw rotation drives the fixed block to move synchronously, thereby adjusting the relative position of the tension rollers. At the same time, the characteristics of the scissor lift are used to maintain stable position changes and stable power transmission. Thus, by simply controlling the rotation of the screw, the positions of multiple tension rollers can be quickly and accurately adjusted, achieving continuous tension adjustment and ensuring the quality of the finished product after bleaching.

[0011] 2. Through the modular design of the adjustment mechanism and the drive mechanism, it can be adapted to different specifications and types of blended yarns to meet diverse production needs. Compared with traditional manual adjustment, it is more efficient and more precise. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1 To be continued Figure 5 The automated blended yarn bleaching device provided by this utility model includes a housing 10, a scissor frame 11, and a tension roller 12. The scissor frame 11 is vertically slidably mounted on the side wall of the housing 10 along its length. The housing 10 has an adjustment mechanism and a drive mechanism inside the side wall corresponding to the scissor frame 11. The adjustment mechanism includes: Multiple fixed blocks 13 are rotatably connected to the middle of one side wall of the scissor lift 11 away from the center of the box 10 and are located on the same horizontal straight line. The top of the side wall of the multiple fixed blocks 13 that are close to each other is horizontally rotatably connected to the same lead screw 14. The driving mechanism includes a motor 20 fixed to the side wall of the fixed block 13 located in the middle away from the scissor lift 11. The drive wheel 15 is rotatably mounted on the bottom of the side wall of the fixed block 13 away from the scissor lift 11. Tensioning wheels 16 are rotatably mounted at multiple rotatable connection points on the bottom side of the scissor lift 11 away from the inside of the housing 10. The same drive belt 17 is fitted into the groove of the tensioning wheel 16 and the wheel groove of the two adjacent drive wheels 15. The tension roller 12 is rotatably connected to the side wall of the scissor lift 11 away from the fixed block 13, corresponding to the positions of the drive wheel 15 and the tension wheel 16 respectively. The side wall of the tension roller 12 near the scissor lift 11 is coaxially fixed with a connecting shaft. The end of the connecting shaft away from the tension roller 12 rotatably passes through the scissor lift 11 and is fixed to the corresponding drive wheel 15 or tension wheel 16. Multiple partition rings are fixed on the outer arc wall of the tension roller 12. The multiple partition rings are linearly and equally spaced along the axial direction of the tension roller 12.

[0016] It should be noted that: the scissor lift 11 includes several sets of scissor arms. Each set of scissor arms includes two scissor arms, namely scissor arm 1 and scissor arm 2, which are rotatably connected to each other. Scissor arms 1 and scissor arms 2 in the same set are stacked on top of each other and are rotatably connected to each other through the same damping shaft 1 in the middle. Scissor arms 1 and scissor arms 2 in adjacent sets of scissor arms are rotatably connected to each other through the same damping shaft 2. Thus, multiple sets of scissor arms are rotatably connected to each other to form a mesh structure. The transmission wheel 15 is coaxially disposed at one point on the damping shaft, and the tension wheel 16 is coaxially disposed at another point on the damping shaft. In one possible embodiment, the transmission wheel 15 is a double-groove pulley, and the tension wheel 16 is a single-groove pulley. The grooves of two adjacent tension wheels 16 are staggered, i.e., not located in the same vertical plane. The lead screw 14 is not located at the same horizontal height as the transmission wheel 15, i.e., the lead screw 14 and the connecting shaft do not interfere with each other. The screw 14 has threads only in the area near the center, meaning that only the two fixing blocks 13 near the center are threaded together. The rest of the screw 14 is smooth and the other fixing blocks 13 do not engage with the screw 14. The separator ring is used to separate multiple spinning fibers during bleaching. The tension roller 12, separator ring, scissor frame 11 and other components are coated with a corrosion-resistant coating to reduce the corrosion of the bleaching liquid. Furthermore, a sealing cover is detachably connected to the top of the housing 10. A gas collection device is provided on the top of the sealing cover to absorb harmful gases during bleaching for subsequent centralized treatment. This will not be elaborated here. A sliding channel for the connecting shaft to slide is provided on the inner wall of the housing 10. At the same time, a sealing plate slides in the sliding channel. That is, both the sliding channel and the sealing plate are adapted to the movement trajectory of the corresponding rotating connection of the scissor lift 11.

[0017] Please see the appendix Figure 1 To be continued Figure 5 The present invention provides a technical solution: a spline sleeve 35 is coaxially fixedly sleeved on the outer side of the output shaft of the motor 20; a sleeve shaft 21 is coaxially sleeved at the outer end of the spline sleeve 35 away from the motor 20; a sleeve shaft 22 is rotatably sleeved on the inner arc wall of the sleeve shaft 21; a transmission gear 23 is coaxially fixed on the outer arc wall of the sleeve shaft 21; a bevel gear 24 is fixed at the outer end of the sleeve shaft 22 away from the motor 20; a sleeve shaft 33 is coaxially slidably sleeved on the outer side of the spline sleeve 35; and the outer end of the sleeve shaft 33 away from the motor 20 is movably inserted into the sleeve shaft 21. On the inner arc wall of sleeve 1 21, near the end of motor 20, there are multiple grooves 1 arranged in a ring array about its axial direction. On the inner arc wall of sleeve 22, near the end of motor 20, there are multiple grooves 2 arranged in a ring array about its axial direction. Grooves 1 and 2 are not located on the same vertical plane, and groove 1 is closer to motor 20. On the outer arc wall of sleeve 33, there are multiple limiting blocks 34 arranged in a ring array about its axial direction. A groove is provided on the outer arc wall of the sleeve shaft 33 at the position corresponding to the position of the limiting block 34. A return spring is fixed at one end of the limiting block 34 near the inner wall of the groove. The end of the return spring away from the limiting block 34 is fixed on the inner wall of the groove. Both sides of the end of the limiting block 34 away from the outer arc wall of the sleeve shaft 33 are rounded along the axial direction of the sleeve shaft 33. The end of the sleeve shaft 33 near the motor 20 is coaxially fixed with a fixed plate 32. A limiting clamp 31 is sleeved on the outer edge of the fixed plate 32. An electric push rod 30 is fixed on the horizontal side of the limiting clamp 31 near the motor 20. The electric push rod 30 is fixed to the top of the motor 20. The limiting clamp 31 has a "door" shaped cross section along the radial section of the fixed plate 32 and the notch faces the fixed plate 32. The transmission gear 23 has a similar structure to the lead screw 14 on the side of the transmission gear 23. The transmission gear 23 located away from the motor 20 is coaxially fixed to the outer arc wall of the lead screw 14. The bevel gear 24 has a vertical annular gear disk 25 on the side away from the lead screw 14. An internal gear ring 27 is coaxially fixed to the inner arc wall of the annular gear disk 25. A horizontal linkage gear 26 is meshed at the bottom end of the inner arc wall of the internal gear ring 27. The end of the linkage gear 26 near the scissor lift 11 is coaxially fixed to the corresponding transmission wheel 15.

[0018] It should be noted that: when the motor 20 starts, it drives the output shaft and the spline sleeve 35 on it to rotate. Since the sleeve shaft 33 is coaxially slidably sleeved on the outside of the spline sleeve 35, the rotation of the output shaft will drive the sleeve shaft 33 to rotate. When the electric push rod 30 extends, it pushes the limit clamp 31 to move, driving the sleeve shaft 33 to move along the axial direction of the spline sleeve 35, thereby connecting it with the sleeve shaft 21 or the sleeve shaft 22. This further enables different fixed shafts 1 and different fixed shafts 2 to form a fixed connection, so as to drive different components to rotate. The sleeve 33 includes two sleeves 4 and 5 with different cross-sectional radii, which are coaxially fixed. The outer arc wall cross-sectional radius of the sleeve 4 is the same as the inner arc wall cross-sectional radius of the sleeve 22. The outer arc wall cross-sectional radius of the sleeve 5 is equal to the inner arc wall cross-sectional radius of the sleeve 11. Both the outer arc walls of the sleeve 4 and the sleeve 5 are provided with limiting blocks 34. That is, the limiting block 34 on the sleeve 4 is inserted into the groove 2 and the limiting block 34 on the sleeve 5 is inserted into the groove 1. When the limiting block 34 on sleeve shaft four is inserted into groove two, the motor 20 will drive the bevel gear 24 to rotate, which in turn drives the corresponding transmission wheel 15 to rotate through the ring gear disk 25, the internal gear ring 27, and the linkage gear 26, thereby driving all the tension rollers 12 to rotate. At this time, the limiting block 34 on sleeve shaft five is not inserted into groove one. When the limiting block 34 on the sleeve shaft 5 is inserted into the groove 1, the motor 20 will drive the transmission gear 23 to rotate, which in turn drives the lead screw 14 to rotate, which in turn drives the multiple fixed blocks 13 to move, which in turn drives the scissor frame 11 to extend and retract to change the relative position of the multiple tension rollers 12.

[0019] Working principle: The housing 10 is equipped with a scissor lift 11, on which tension rollers 12 are mounted. In the adjustment mechanism, multiple fixed blocks 13 are connected by a screw 14. Rotating the screw 14 can adjust the spacing between the fixed blocks 13, thereby changing the relative position of the tension rollers 12 on the scissor lift 11 to control the yarn tension. The drive mechanism is based on motor 20. Its output shaft is connected to sleeve shaft 33 via spline sleeve 35. Electric push rod 30 pushes limit clamp 31 to make sleeve shaft 33 slide switch connection: when it meshes with sleeve shaft 21, transmission gear 23 drives lead screw 14 to rotate. When meshing with the sleeve shaft 22, the bevel gear 24 drives the transmission wheel 15 to rotate via the ring gear disk 25, the internal gear ring 27, and the linkage gear 26. The transmission belt 17 links the tension wheel 16, causing the tension roller 12 to rotate and convey the yarn. The separating ring separates the yarn, the corrosion-resistant coating reduces the corrosion of the bleaching liquid, and the gas collection equipment treats harmful gases, ensuring that the bleaching process is efficient and safe.
