Description

Technical Field

[0001] This invention relates to the field of fabric impregnation technology, and more specifically to an impregnation device for fabric dyeing and finishing. Background Technology

[0002] Pulping equipment is a key machine in textile dyeing and finishing. It is mainly used to immerse fabrics (such as knitted fabrics, cotton fabrics, cotton fabrics and blended fabrics, etc.) in various treatment solutions (such as dyes, finishing agents, etc.), and then roll them evenly with rollers to allow the treatment solution to fully penetrate the fabric and remove excess liquid.

[0003] Fabric padding rollers are generally divided into upper and lower rollers. In traditional technology, the bearing seats at both ends of the lower roller are driven by a pneumatic or hydraulic system (cylinder or hydraulic cylinder, etc.) to make vertical linear motion, so as to adjust the padding gap. However, since the gap variation range required by the padding process is extremely small (often millimeters or even sub-millimeter level), this mode of extremely short linear movement stroke places extremely high demands on the control precision of the drive system. To achieve micron-level linear displacement control, it is necessary to use a high-precision servo system, a high-grade lead screw or a precision hydraulic servo valve. All of these lead to high system complexity, high manufacturing cost, and high sensitivity to external interference (such as oil temperature changes, air pressure fluctuations, mechanical vibration), which also increases maintenance cost and difficulty. In order to reasonably improve this problem, this invention proposes a padding device for fabric dyeing and finishing. Summary of the Invention

[0004] To achieve the above objectives, the present invention specifically adopts the following technical solution: A fabric dyeing and finishing padding apparatus, comprising: U-shaped frame; The upper roll is rotatably mounted on the inner wall of the U-shaped frame. Two guide rolls are rotatably mounted on the U-shaped frame and are respectively located on both sides of the top of the upper roll. The lower roll has movable parts at both ends, and the two movable parts are respectively movable to the inner wall of the U-shaped frame. The movable parts include an annular plate rotatably mounted on the U-shaped frame through bearings. The end of the lower roll is rotatably engaged with the annular plate, and the upper roll is eccentrically located inside the annular plate. A pressure regulating mechanism, mounted on a U-shaped frame, is used to drive two movable parts to move along a preset arc-shaped trajectory. The upper roller is eccentrically positioned inside the arc of the trajectory. As the movable parts move along the arc-shaped trajectory, the distance between the lower roller and the upper roller gradually decreases until they contact each other or reach a preset relative position. The pressure regulating mechanism includes a guide post constructed on the outer side of an annular plate. An arc-shaped groove for the guide post to pass through is provided on the outer wall of the U-shaped frame. The arc-shaped groove is concentric with the annular plate. A movable plate is slidably fitted at the bottom of the U-shaped frame. Vertical plates are vertically connected to both ends of the movable plate. A strip groove is provided on the vertical plate. A roller is rotatably mounted on the guide post. The roller is tangentially rolled with the inner wall of the strip groove. The drive unit, located on the U-shaped frame, is used to drive the lower roll to rotate along its own axis; The self-compensating component, located on the vertical plate, adaptively compensates for wear generated during the operation of the roller.

[0005] Furthermore, the central angle corresponding to the arc-shaped groove is greater than 90 degrees and less than 180 degrees, and a scale is engraved on the side of the arc-shaped groove to indicate the distance between the lower roll and the upper roll.

[0006] Furthermore, the self-compensating component includes an adjusting plate slidably mounted on the inner wall of the strip groove, a roller movably overlapping the two adjusting plates on opposite sides, an elastic component on the vertical plate, which can continuously apply a pushing force to the two adjusting plates to move closer to each other, and a self-locking component on the vertical plate, which is used to constrain the sliding direction of the adjusting plate so that it can only slide in a single direction, thereby realizing the self-locking function.

[0007] Furthermore, the elastic component includes two sets of guide rods constructed on opposite sides of the two adjusting plates, and the two sets of guide rods slide through the opposite inner walls of the strip groove. Each end of the guide rod is provided with a connecting block, and the connecting block is connected to the vertical plate by a tension spring. The vertical plate is provided with a linkage component, and the two adjusting plates are linked together by the linkage component so that during the adaptive compensation of the adjusting plate according to the wear of the roller, its axis is always located on the central axis of the strip groove.

[0008] Furthermore, the linkage component includes a spur gear rotatably mounted on the vertical plate, and the adjusting plate has plates staggered on opposite sides. Each of the two plates has a rack connected to its opposite side and meshes with the two sides of the spur gear respectively.

[0009] Furthermore, the self-locking assembly includes a horizontal plate constructed at the end of the adjusting plate, a strip ratchet connected to the horizontal plate, a fixing block constructed on the vertical plate, a slot for accommodating the strip ratchet on the fixing block, a plurality of abutments hinged in the slot, the abutment shaft being connected to the fixing block via a torsion spring, the movable end of the abutment abutting against the strip ratchet, and the plurality of abutments being respectively positioned on different parts of different ratchet teeth on the strip ratchet under the drive of the torsion spring.

[0010] Furthermore, the drive unit includes a mounting plate connected to the U-shaped frame, on which a rotating rod is rotatably mounted, coaxial with the annular plate. A first sprocket and a second sprocket are respectively connected to both ends of the rotating rod. The end of the lower roller coaxially passes through the guide post, and a third sprocket is connected thereto and is connected to the first sprocket via a first chain drive. One of the guide rollers is connected to a fourth sprocket at its end, which is connected to the second sprocket via a second chain drive.

[0011] The beneficial effects of this invention are as follows: This solution transforms the high-precision linear micro-displacement control problem between the lower and upper rolls into low-precision arc displacement control through an ingenious arc motion mechanism design. This allows for the adjustment of the gap between the lower and upper rolls in another way. This design cleverly utilizes the stroke amplification principle. When the pressure regulating mechanism drives the moving part to move a long arc distance along the arc trajectory, the resulting change in the gap between the lower and upper rolls is very small. This means that a complex control objective can be achieved through a simple mechanical structure, i.e., the gap between the lower and upper rolls can be controlled with relatively low driving precision.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0015] like Figures 1-8 As shown, an embodiment of the present invention provides an impregnation and padding apparatus for fabric dyeing and finishing, comprising: U-shaped frame 1, one side of which is connected to the dyeing box for dyeing fabric, and the bottom surface of the U-shaped frame 1 is constructed with an inclined surface 9. The dyeing box is located at the lower end of the inclined surface 9 so that the treatment liquid falling on the inside of the U-shaped frame 1 can slide along the inclined surface 9 and fall back into the dyeing box. The upper roller 2 is rotatably mounted on the inner wall of the U-shaped frame 1. Two guide rollers 3 are rotatably mounted on the U-shaped frame 1 and are respectively located on the top two sides of the upper roller 2. The two guide rollers 3 are connected by the existing belt pulley mechanism 10. The fabric is sequentially wrapped around the first guide roller 3, the upper roller 2 and the second guide roller 3. That is, this section of fabric wraps around the upper roller 2 in a V-shaped path. The lower roller 4 has movable parts 5 at both ends, and the two movable parts 5 are respectively movable to the inner wall of the U-shaped frame 1. The lower roller 4 is mounted on the U-shaped frame 1 through the two movable parts 5. The position of the lower roller 4 can be adjusted by driving the two movable parts 5 to move on the U-shaped frame 1. The movable parts 5 include a bearing 501 and an annular plate 502. The annular plate 502 is rotatably mounted on the U-shaped frame 1 through the bearing 501. The end of the lower roller 4 is rotatably engaged with the annular plate 502. The upper roller 2 is eccentrically located on the inner side of the annular plate 502. When the annular plate 502 rotates, the lower roller 4 revolves along the axis of the annular plate 502, thereby adjusting the distance between it and the upper roller 2. The lower roller 4 moves precisely and stably along a preset arc trajectory with the axis of the annular plate 502 as the center during the above process, and is not prone to mechanical interference. The lower roller 4 can rotate on the annular plate 502 under the action of the drive unit 7, and cooperate with the upper roller 2 to press the fabric. A pressure regulating mechanism 6, mounted on the U-shaped frame 1, drives two movable parts 5 to move along a preset arc-shaped trajectory. The upper roller 2 is eccentrically positioned inside the arc of the trajectory, meaning the axis of the upper roller 2 lies between the arc formed by the trajectory and its center. As the movable parts 5 move along the arc-shaped trajectory, the distance between the lower roller 4 and the upper roller 2 gradually decreases until they contact each other or reach a preset relative position. Compared with existing technologies using linear motion, the arc-shaped motion design can provide a longer working stroke than linear guidance. The pressure regulating mechanism 6 includes a guide post 601 constructed on the outer side of the annular plate 502. The outer wall of the U-shaped frame 1 has an arc-shaped groove 602 for the guide post 601 to pass through. The outer diameter of the guide post 601 is smaller than the inner diameter of the arc-shaped groove 602, meaning the guide post 601 and the arc-shaped groove 602 are connected. 2. Non-contact, the arc groove 602 is concentric with the annular plate 502, the bottom of the U-shaped frame 1 is slidably fitted with a movable plate 603, the two ends of the movable plate 603 are vertically connected with vertical plates 604, the two vertical plates 604 are respectively slidably fitted with the opposite sides of the U-shaped frame 1, the vertical plates 604 are provided with strip grooves 605, the guide post 601 is rotatably mounted with a roller 606, the roller 606 is tangentially rolled with the inner wall of the strip groove 605, the roller 606 is located at the overlap of the strip groove 605 and the arc groove 602. This design can link the two annular plates 502 together, that is, when the movable plate 603 drives the two vertical plates 604 to slide, under the abutment of the inner wall of the strip groove 605, the two guide posts 601 can drive the two annular plates 502 to rotate along their own axis, thereby synchronously adjusting the distance between the lower roller 4 and the upper roller 2; It should be specifically noted here that the movable plate 603 can be driven to slide on the U-shaped frame 1 by a drive component such as a cylinder, hydraulic cylinder or lead screw motor; For example, assuming a large arc radius and a stroke magnification ratio of 100:1, if the lower roller 4 moves 1 cm on the arc trajectory, the distance between it and the upper roller 2 only changes by 0.1 mm. This means that to achieve a distance control accuracy of 0.01 mm, only a control accuracy of 1 mm is needed. This means that the drive control accuracy of the pressure regulating mechanism 6 can be much smaller than the distance control accuracy between the lower roller 4 and the upper roller 2. In other words, by adopting the above structural design, the accuracy requirements for adjusting the distance between the lower roller 4 and the upper roller 2 can be greatly reduced. This makes it possible to use a lower-cost, simpler, and more reliable ordinary screw motor or standard cylinder as the drive source. To a certain extent, it can replace expensive and complex high-precision hydraulic or servo linear drive systems. At the same time, since the pressure regulating mechanism 6 no longer needs to maintain extremely high linear positioning accuracy, its sensitivity to external force factors such as force changes, temperature drift, and medium pressure fluctuations is greatly reduced, which can reduce the impact of external force factors on it. The drive unit 7 is mounted on the U-shaped frame 1 and is used to drive the lower roller 4 to rotate along its own axis. The upper roller 2 rotates by friction with the lower roller 4 and by the movement of the fabric. The self-compensating component 8 is installed on the vertical plate 604. The self-compensating component 8 can adaptively compensate for the wear generated during the operation of the roller 606. During the long-term operation of the equipment, the self-compensating component 8 can automatically eliminate the transmission gap caused by the wear of the roller 606, ensuring that the core parameters of the pressure regulating mechanism 6, such as the roller spacing, remain accurate and consistent. This ensures the uniformity of the liquid-squeezing effect of the fabric, makes the process parameters less prone to drift, and improves the stability of product quality. This solution transforms the high-precision linear micro-displacement control problem between the lower roll 4 and the upper roll 2 into low-precision arc displacement control through an ingenious arc motion mechanism design. This allows for adjustment of the distance between the lower roll 4 and the upper roll 2 in a different way. This design cleverly utilizes the stroke amplification principle; when the pressure regulating mechanism 6 drives the moving part 5 to move a long arc distance along the arc trajectory, the resulting change in the distance between the lower roll 4 and the upper roll 2 is very small. This means that a complex control objective can be achieved through a simple mechanical structure—that is, the distance between the lower roll 4 and the upper roll 2 can be controlled with relatively low driving precision. Compared with existing technologies, this invention overcomes the pain points of high cost, high complexity, high maintenance requirements, and sensitivity to external interference in traditional technologies, providing a new technical path for achieving high-performance, low-cost fabric impregnation equipment.

[0016] like Figure 2As shown, in some embodiments, the central angle corresponding to the arc groove 602 is greater than 90 degrees and less than 180 degrees. By adopting the above design, not only can the lower roller 4 have a sufficiently long arc adjustment stroke to meet the adjustment range requirements from the maximum pitch to the working pitch, but also, within this angle range, when the vertical plate 604 slides horizontally and drives the roller 606 to move, the roller 606 will not abut against the inner wall of the arc groove 602 along the sliding direction of the vertical plate 604, thus making it less prone to jamming. The side of the arc groove 602 is engraved with markings for indicating the lower roller 4. As mentioned above, the scale indicating the distance between the upper and lower rollers 2 is related to the arc-shaped movement distance of the lower roller 4 when the annular plate 502 is rotated and the distance between the upper and lower rollers 2. The arc length "movement distance of the lower roller 4" = arc radius "length from the center of the annular plate 502 to the axis of the lower roller 4" × central angle "rotation angle of the annular plate 502". The essence of the scale is to directly map and display the rotation angle of the annular plate 502 as a high-precision distance value between the upper and lower rollers 2 and 4. That is, to convert low-precision angular displacement into high-precision distance reading. This invention solves the problem of the difficulty in intuitively judging the spacing under arc-shaped motion by directly setting a scale corresponding to the arc-shaped trajectory on the side of the arc-shaped groove 602. Operators or automated systems can directly read the scale value to accurately and in real time know the actual spacing between the two rolls without relying on complex indirect measurements or calculations. This facilitates the precise pre-setting of different process parameters, such as different fabrics and different liquid yield requirements, and effectively improves production efficiency.

[0017] like Figure 3 , Figure 6 and Figure 7As shown, in some embodiments, the self-compensating component 8 includes adjusting plates 801 slidably mounted on the inner walls of the strip groove 605. The two adjusting plates 801 are slidably arranged relative to each other. The roller 606 is movably overlapped with the opposite sides of the two adjusting plates 801. An elastic component 802 is provided on the vertical plate 604. The elastic component 802 can continuously apply a pushing force to the two adjusting plates 801, causing them to move closer together. The elastic component 802 provides a continuous and stable pushing force to the adjusting plates 801, forcing the roller 606 to always be in close contact with the adjusting plates 801, thereby automatically and instantly compensating for wear and ensuring gapless power transmission. The 04 is equipped with a self-locking component 803, which is used to constrain the sliding direction of the adjusting plate 801, so that it can only slide in a single direction, thereby realizing the self-locking function. The key function of the self-locking component 803 is to constrain the adjusting plate 801 to move only in the "compensation direction" towards the roller 606, effectively preventing it from being pushed back under the action of rolling vibration or reverse force. This "only forward and no backward" mechanism ensures the irreversibility and accumulation of the compensation amount, making the compensation action accurate and reliable, and it is not easy for the accuracy to fail due to the recurrence of gaps. It can ensure the transmission accuracy of the adjusting mechanism during long-term operation of the equipment.

[0018] like Figure 3 and Figure 6 As shown, in some embodiments, the elastic component 802 includes two sets of guide rods 8021 constructed on opposite sides of the two adjusting plates 801. In this invention, the number of a single set of guide rods 8021 is at least three, and the two sets of guide rods 8021 slide through the opposite inner walls of the strip groove 605 respectively. The guide rods 8021 penetrate the vertical plate 604, and each end of the guide rod 8021 is constructed with a connecting block 8022. The connecting block 8022 is away from the adjusting plate 801, and its outer diameter is larger than the outer diameter of the guide rod 8021. The connecting block 8022 is connected to the vertical plate 604 by a tension spring 8023. The tension spring 8023 is used to provide a tension force to force the connecting block 8022 to move toward the vertical plate 604, so that the adjusting plate 801 can be placed on the outer side of the roller 606 under the action of tension. The vertical plate 604 is equipped with a linkage component 8024. The two adjusting plates 801 are linked together through the linkage component 8024 so that during the adaptive compensation of the adjusting plate 801 according to the wear of the roller 606, its axis is always located on the central axis of the strip groove 605. The linkage component 8024 ensures that the two adjusting plates 801 move strictly synchronously and symmetrically at any compensation position, ensuring that the axis of the adjusting plate 801 always coincides with the central axis of the strip groove 605, so that the axis of the roller 606 is always aligned. This allows the entire working surface of the roller 606 to achieve uniform and comprehensive contact with the adjusting plate 801, avoiding local stress concentration and abnormal damage caused by unilateral wear or uneven wear, and greatly extending the service life of all related components.

[0019] like Figure 6As shown, in some embodiments, the linkage component 8024 includes two spur gears 80241 rotatably mounted on the vertical plate 604, respectively located at both ends of the strip groove 605. The adjusting plates 801 are staggered with plate bodies 80242 on opposite sides, and each adjusting plate 801 is equipped with two plate bodies 80242. The two plate bodies 80242 are connected to racks 80243 on opposite sides and mesh with the two sides of the spur gears 80241 respectively. When one adjusting plate 801 needs to move, the rack 80243 on it will drive the spur gears 80241, and the spur gears 80241 will drive the rack 80243 on the other adjusting plate 801 to perform a completely reverse and equal amount of compensating movement.

[0020] like Figure 6 and Figure 7 As shown, in some embodiments, the self-locking assembly 803 includes a horizontal plate 8031 ​​constructed at the end of the adjusting plate 801. Both ends of the adjusting plate 801 have horizontal plates 8031. A strip-shaped ratchet 8032 is connected to the horizontal plate 8031. A fixing block 8033 is constructed on the vertical plate 604. Fixing blocks 8033 are provided at each of the four corners of the vertical plate 604. The fixing blocks 8033 have slots 8034 for accommodating the strip-shaped ratchet 8032. The slots 8034 are formed in the fixing blocks 8033 facing the horizontal plate. On one side of plate 8031, and through the opposite side of fixed block 8033, multiple abutments 8035 are hinged within the through groove 8034. The rotating shaft of abutment 8035 is connected to fixed block 8033 via torsion spring 8036. The fixed end of torsion spring 8036 is connected to fixed block 8033, and the movable end is connected to the rotating shaft of abutment 8035. The movable end of abutment 8035 moves against the strip ratchet 8032. This design adopts a purely mechanical ratchet and pawl structure principle. Under the action of torsion spring 8036, abutment 8035... The pads are tightly locked into the grooves of the ratchet 8032, effectively resisting vibrations, impacts, or reverse forces from the roller 606 during equipment operation. This ensures the irreversibility and absolute reliability of wear compensation. Multiple abutments 8035, driven by the torsion spring 8036, are respectively positioned on different parts of different ratchet teeth on the ratchet 8032. In this invention, the number of abutments 8035 is at least three. When the end of the first abutment 8035 is engaged with one of the ratchet teeth on the ratchet 8032... When the bottom ends of the tooth surfaces contact each other, the first stop block 8035 locks onto the strip ratchet 8032. At the same time, the end of the second stop block 8035 is movably attached to the middle of another ratchet tooth surface, and the end of the third stop block 8035 is movably attached to the tip of yet another ratchet tooth. In this invention, by adopting a design of multiple stop blocks 8035 in a staggered layout, a seamless "relay" locking can be formed, that is, continuous and uninterrupted anti-backward protection can be provided in any position, with a high level of safety.

[0021] like Figure 1 and Figure 2As shown, in some embodiments, the drive unit 7 includes a mounting plate 701 connected to the U-shaped frame 1. A rotating rod 702 is rotatably mounted on the mounting plate 701, which is coaxial with the annular plate 502. The two ends of the rotating rod 702 are respectively connected to a first sprocket 703 and a second sprocket 704. The end of the lower roller 4 coaxially passes through the guide post 601, and a third sprocket 705 is connected to it. It should be specifically noted that no matter where the lower roller 4 moves, the distance between the third sprocket 705 and the first sprocket 703 is always consistent, and it is connected to the first sprocket 703 through a first chain 706. When the first sprocket 703 rotates, it can drive the third sprocket 705 to drive the lower roller 4 to rotate through the first chain 706. One of the guide rollers 3 is connected to a fourth sprocket 707 at its end, which is connected to the second sprocket 704 through a second chain 708. By adopting the above design, the lower roller 4 and the guide roller 3 can be linked together so that they rotate synchronously.

[0022] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
