Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fabric processing, in particular to a dyeing auxiliary traction conveying equipment based on flat-cut fabric. BACKGROUND

[0002] Flat-cut fabric, as a kind of textile fabric with unique texture and cutting characteristics, is widely used in clothing, home decoration and other fields. The dyeing process of flat-cut fabric has high requirements for fabric surface cleanliness and conveying stability, which directly affects the appearance quality and market competitiveness of the final product. In the dyeing production process of flat-cut fabric, the dyeing auxiliary traction conveying equipment is the core supporting equipment, mainly responsible for the traction, conveying and roller cleaning of the dyed fabric, and its performance directly determines the efficiency and product qualification rate of dyeing.

[0003] The core components of the existing flat-cut fabric dyeing traction conveying equipment are mainly conveying rollers, drive motors and simple guide structures. The primary problem is the lack of or inefficiency of dye residue cleaning mechanism for the conveying rollers. During the traction and conveying process of the dyed fabric, the excess dye attached to the surface of the fabric is easily transferred to the outer arc surface of the conveying roller. However, the existing equipment generally does not have a targeted cleaning device, and only a few devices are equipped with a fixed rigid scraper. This type of rigid scraper has two fatal defects: first, the fit between the scraper and the outer arc surface of the roller is poor, and due to manufacturing errors and installation deviations, a cleaning blind area is easily formed, and the residual dye is repeatedly transferred to the surface of the subsequent fabric with the roller, resulting in quality problems such as color stains and color differences in the fabric; second, rigid contact can cause surface wear of the roller, reducing the service life of the roller, and the scraper itself is prone to deformation, further reducing the cleaning effect. Although some improved solutions use elastic scrapers, they can only achieve linear cleaning in one direction, and the cleaning ability for stubborn dye residues attached to the surface of the roller is limited, which cannot adapt to the characteristics of various forms of dye residues after dyeing of flat-cut fabric.

[0004] Secondly, the cleaning component of the existing equipment lacks flexible posture adjustment and motion coordination mechanism. On the one hand, the position of the cleaning component is fixed, and it cannot be adjusted adaptively according to the length, diameter and other parameters of the conveying roller. When the production line changes different specifications of flat-cut fabric or rollers, the cleaning structure needs to be disassembled and reassembled, which is tedious and has low adjustment precision, seriously affecting the production efficiency. On the other hand, the existing equipment does not consider the cleaning problem of the cleaning component itself. The dye accumulated during the cleaning process will adhere to the surface of the scraper, causing secondary pollution of the roller and fabric during the subsequent cleaning process, forming a vicious cycle of "pollution-cleaning-re-pollution".

[0005] Therefore, a dyeing auxiliary traction conveying equipment based on flat-cut fabric is proposed to solve the above problems. SUMMARY

[0006] In view of the deficiencies of the prior art, the present application provides a dyeing auxiliary traction conveying device based on flat cutting fabric to solve the problems raised in the background art.

[0012] As a preferred, the driving device is electrically controlled by the auxiliary system, an output shaft of the driving device is fixedly connected with the gear through the sliding block, the guide column is slidingly connected in the annular groove, and the gear is meshingly connected with the tooth blocks on the outer ring of the annular rack.

[0013] As a preferred, the second assembly comprises: a U-shaped connecting frame fixedly connected above the driving device, an arc-shaped conductor being fixedly connected to one end of the U-shaped connecting frame away from the driving device, a sleeving ring body being slidingly sleeved on the arc-shaped conductor, and a scraper being fixedly connected to the surface of the sleeving ring body away from the arc-shaped conductor.

[0014] The third assembly is used for removing the dye impurities accumulated on the scraper.

[0015] Preferably, the U-shaped connecting frame is equal in length to the diameter of the conveying roller shaft, the conveying roller shaft and the fixed frame are arranged perpendicularly in the same horizontal plane, the arc-shaped conductor is in a concave arc shape, the scraper is made of silica gel, the arc surface of the side of the scraper away from the sleeved ring body is adapted to the outer arc of the conveying roller shaft, and the scraper is in an inclined state.

[0016] Preferably, the second assembly further comprises a guide frame fixedly connected to the U-shaped connecting frame, the guide frame is arranged below the arc-shaped conductor, a drive screw is rotatably connected in the guide frame, the drive screw is connected to an external power supply and is electrically connected to the auxiliary system for control, a moving block is slidably connected to the outer circle of the drive screw, the moving block is slidably connected in the guide frame, the moving block extends upward, a connecting body is slidably sleeved on the outer circle of the extending end of the moving block, and one end of the connecting body away from the moving block is rotatably connected to the side surface of the sleeved ring body.

[0017] Preferably, the third assembly comprises a positioning frame fixedly connected to the traction frame, a telescopic rod is arranged in the positioning frame, one end of the telescopic rod is fixedly connected to the inner wall of the positioning frame, the other end of the telescopic rod is fixedly connected to an auxiliary block, a return spring is sleeved on the outer circle of the telescopic rod, and the two ends of the return spring are fixedly connected to the inner wall of the positioning frame and the auxiliary block, respectively, a moving wheel is rotatably connected below the auxiliary block, a vertical rod is fixedly connected above the auxiliary block, and a silica gel arc plate is fixedly connected to one end of the vertical rod away from the auxiliary block.

[0018] Preferably, the positioning frame is arranged below the side of the conveying roller shaft, the silica gel arc plate is arranged in an inclined manner, and the silica gel arc plate and the scraper are oppositely inclined and intersected.

[0019] Compared with the prior art, the present application provides a dyeing auxiliary traction conveying device based on flat shearing fabric, which has the following advantages: through the arrangement of the first assembly, in terms of lifting adjustment, the driving device drives the gear to mesh and transmit along the annular rack, the guide column synchronously slides in the annular groove to ensure transmission stability, the rotary motion of the gear is converted into the up-down sliding of the sliding block along the vertical guide groove, and the second assembly as a whole realizes lifting; when the gear meshes with the upper half of the tooth block of the annular rack, the scraper is lifted to the state of being attached to the conveying roller shaft to perform scraping; when the gear meshes with the lower half of the tooth block, the scraper is lowered and separated, facilitating the cleaning of the scraper; in terms of transverse movement, the C-shaped clamping body can slide transversely along the fixed frame, driving the second assembly as a whole to adjust the position, and ensuring that the scraper is adapted to conveying roller shafts of different lengths. Especially in the cleaning process of the scraper, the design of downward separation makes the scraper completely separate from the conveying roller shaft, avoids the incomplete cleaning of the position where the scraper is attached to the outer arc of the conveying roller shaft, and avoids the secondary attachment of the scraper to the conveying roller shaft, and provides sufficient operation space for the silica gel arc plate to clean the scraper.

[0020] Through the adaptive design of the second assembly and the conveying roller shaft, efficient cleaning of the dye on the surface of the roller shaft is realized. On the one hand, the scraper is made of silica gel material, the arc surface close to the conveying roller shaft is precisely adapted to the outer arc of the conveying roller shaft, and is arranged in an inclined state, which greatly improves the adhesion to the surface of the roller shaft, ensures that the cleaning surface covers the entire outer arc surface of the roller shaft, and avoids the generation of cleaning blind area due to poor adhesion. On the other hand, the cleaning action is linked with the rotation of the conveying roller shaft, and on the basis of the adhesion of the scraper to the roller shaft, the continuous rotation of the conveying roller shaft enables the scraper to clean the circumferential surface of the roller shaft in all directions. Through this design, the residual dye on the surface of the conveying roller shaft is effectively removed, avoiding the problem of residual dye pollution of subsequent processing fabrics from the source, preventing the change of the friction coefficient of the roller shaft caused by the adhesion of the dye, and ensuring the stability of the fabric conveying, thereby improving the product qualification rate of the flat-cut fabric dyeing process.

[0021] Through the cooperation of the first assembly and the second assembly, the meshing movement of the gear of the first assembly around the ring gear controls the radial reciprocating movement of the second assembly on the outer ring of the conveying roller shaft. The scraper in the second assembly further realizes the arc trajectory swing of the scraper around the conveying roller shaft under the setting of the arc-shaped conductor. Under the self-rotation of the conveying roller shaft and the opposite rotation of the scraper, the reverse force and the composite motion trajectory are superimposed, the scraper can form multi-directional peeling force on the stubborn dye residue on the surface of the roller shaft, significantly improve the thoroughness of cleaning, and avoid the difficulty of removing stubborn residues in a single cleaning direction.

[0022] Through the linkage work of multiple assemblies, when the scraper moves to the side of the third assembly with the second assembly, the inner arc surface thereof is attached to the outer arc surface of the silica gel arc plate of the third assembly. Under the control of the auxiliary system, the second assembly drives the scraper to move downward, and since the height of the silica gel arc plate is fixed, the silica gel arc plate can form a reverse scraping force on the dye impurities accumulated on the cleaning surface of the scraper during the downward movement of the scraper. At the same time, when the scraper moves along the concave parabolic trajectory of the arc-shaped conductor, it will push the silica gel arc plate to slide along the positioning frame with the auxiliary block, and the return spring outside the telescopic rod will be compressed synchronously, so as to ensure that the silica gel arc plate is always attached to the scraper. After cleaning, the release of the elastic force of the return spring makes the silica gel arc plate reset standby. The synchronous operation of the scraping function and the self-cleaning function of the scraper is realized, which avoids the re-attachment of the dye impurities remaining on the scraper to the surface of the conveying roller shaft or the processed fabric in the subsequent cleaning process, forming a closed-loop cleaning mechanism of “cleaning-self-cleaning-re-cleaning”.

[0049] A further embodiment: Please refer to Figures 9 to 10The third assembly comprises a positioning frame 41 fixedly connected to the traction frame 11, a telescopic rod 42 arranged in the positioning frame 41, one end of the telescopic rod 42 being fixedly connected to the inner wall of the positioning frame 41, the other end of the telescopic rod 42 being fixedly connected to an auxiliary block 44, a return spring 43 being sleeved on the outer ring of the telescopic rod 42, the two ends of the return spring 43 being fixedly connected to the inner wall of the positioning frame 41 and the auxiliary block 44 respectively, a moving wheel 45 being rotatably connected to the lower portion of the auxiliary block 44, a vertical rod 46 being fixedly connected to the upper portion of the auxiliary block 44, a silica gel arc plate 47 being fixedly connected to the end of the vertical rod 46 away from the auxiliary block 44, and the scraper 38 moving to one end of the third assembly, under the assistance of the arc surface tooth block at one end of the annular rack 24, the gear 29 moving to the lower half of the C-shaped clamping body 25, the scraper 38 being separated from the adhering state with the conveying roller shaft 21, and at the same time, the driving screw 34 rotating to control the sleeved ring body 37 to move from the left side of the arc-shaped conductor 32 to the other side, in the initial state, the auxiliary block 44 and the silica gel arc plate 47 are synchronously arranged on the left side of the positioning frame 41, and the scraper 38 is arranged on the synchronous horizontal line, so that the scraper 38 moves on the arc-shaped conductor 32 from left to right, and the scraper 38 has a downward moving trend due to the concave arrangement of the arc-shaped conductor 32, and the scraper 38 moves upward again when it reaches the bottom end of the arc-shaped conductor 32, and the scraper 38 moves from left to right and crosses the silica gel arc plate 47, thereby pushing the silica gel arc plate 47 and the vertical rod 46 and the auxiliary block 44 to move synchronously from left to right in the positioning frame 41, and the return spring 43 and the telescopic rod 42 are compressed, the scraper 38 moves from left to right and downward, and the dye adhered to the arc surface of the scraper 38 is scraped off by the silica gel arc plate 47, and the moving wheel 45 assists the auxiliary block 44 to improve the smoothness of movement.

[0050] The positioning frame 41 is arranged below the conveying roller shaft 21, the silica gel arc plate 47 is arranged in an inclined manner, and the silica gel arc plate 47 and the scraper 38 are oppositely inclined and cross each other.

[0051] The C-shaped clamping body 25 is slidably clamped on the fixed frame 22, and the operator can adjust the lengths of the annular rack 24 and the fixed frame 22 according to the length of the conveying roller shaft 21, so as to adapt to the length of the conveying roller shaft 21, thereby driving the second assembly to move as a whole, ensuring that the scraper 38 covers the entire axial length of the conveying roller shaft 21 and ensuring the cleaning frequency to avoid the cleaning blind area.

[0052] The working principle of all the contents in the above embodiment is as follows: in the initial state, the auxiliary system 14 is synchronously electrically connected to the traction frame 11, the conveying frame 12 and each drive, and the parameter setting is completed. At this time, the fabric 13 is laid on the conveying roller shaft 21 of the traction frame 11 and the conveying frame 12, and the dyeing tank is located on the side of the traction frame 11 away from the conveying frame 12, and the fabric enters the dyeing process.

[0053] In use, the auxiliary system 14 controls the synchronous movement of the traction frame 11 and the conveying frame 12, the conveying roller shaft 21 is driven to rotate by the external motor, and the rotating drives the movement of the dyed processing fabric 13, at this time, the gear 29 is driven by the driving device 28 to mesh with the upper half of the ring-shaped rack 24, the guide column 210 slides in the ring-shaped groove 23 to follow the movement of the gear 29, the stability of the auxiliary gear 29 limits the movement deviation, when the gear 29 rotates to the both sides of the gear 29, it moves up and down along the ring-shaped rack 24, and further drives the slider 27 fixedly connected with the driving device 28 to slide up and down along the vertical guide groove 26 on the C-shaped clamping body 25, so as to realize the lifting adjustment of the driving device 28 and the second assembly; when the gear 29 meshes with the upper half of the ring-shaped rack 24, the driving device 28 is located in the upper half of the C-shaped clamping body 25, the second assembly is synchronously lifted, the scraper 38 is closely attached to the outer arc surface of the conveying roller shaft 21, because the arc surface of the side of the scraper 38 close to the conveying roller shaft 21 is adapted to the outer arc of the conveying roller shaft 21, the attachment degree is higher in the inclined state, and the cleaning surface is wider, and when the gear 29 rotates and the driving device 28 and the second assembly reciprocate along the upper tooth surface of the ring-shaped rack 24, the scraper 38 is attached to the outer arc surface of the conveying roller shaft 21, and moves from one side to the other side of the conveying roller shaft 21, under the cooperation of the self-rotation of the conveying roller shaft 21, the cleaning work of the outer arc surface of the conveying roller shaft 21 is completed, so as to avoid the dye adhering to the conveying roller shaft 21 to affect the conveying of the processing fabric 13 and the dye adhering to the processing fabric 13 to affect the product quality.

[0054] After the scraper 38 is attached to the conveying roller shaft 21, the auxiliary system 14 controls the driving screw 34 to start rotating. When the driving screw 34 rotates, the moving block 35 connected to the outer ring of the driving screw 34 moves linearly along the inside of the guide frame 33. Since the outer ring of the end part extending upward of the moving block 35 is sleeved with the connecting body 36, and the end of the connecting body 36 away from the moving block 35 is rotationally connected to the side of the sleeved ring body 37, the reciprocating movement of the moving block 35 is converted into the reciprocating sliding of the sleeved ring body 37 along the arc-shaped conductor 32 through the connecting body 36. Under the action of the lower concave arc of the arc-shaped conductor 32, the connecting body 36 is limited by the sleeved ring body 37 and the moving block 35, and the connecting body 36 moves reciprocally with the moving block 35. According to the arc surface of the arc-shaped conductor 32, the connecting body 36 slides up and down on the outer ring of the moving block 35 to adapt to the arc of the arc-shaped conductor 32. The connecting body 36 is rotationally connected to the sleeved ring body 37, which drives the sleeved ring body 37 to move synchronously on the arc-shaped conductor 32 while the connecting body 36 moves, thereby driving the scraper 38 to adjust the position of the scraper 38 attached to the conveying roller shaft 21 for cleaning. Under the cooperation of the reciprocating movement of the scraper 38 and the arc-shaped movement of the arc-shaped conductor 32, the scraper 38 presents a complex movement track and cooperates with the rotation of the conveying roller shaft 21. The rotation of the scraper 38 and the conveying roller shaft 21 is opposite to each other, so as to more completely clean the dye on the conveying roller shaft 21 under the interaction force and the complex movement track. The inclined state of the scraper 38 makes the cleaned dye slide down under the action of gravity, avoiding the cleaned dye from affecting the processed fabric 13.

[0055] When the scraper 38 moves to the side of the third assembly, the inner arc surface of the scraper 38 is attached to the outer arc surface of the silica gel arc plate 47, and during the transmission of the gear 29 and the ring gear 24, the gear 29 cooperates with the driving device 28 and the sliding block 27 to slide in the vertical guide groove 26 to the lower side of the C-shaped clamping body 25. When the gear 29 cooperates with the second assembly to move downward, the scraper 38 is attached to the outer arc surface of the silica gel arc plate 47 to move downward, and during the downward movement of the scraper 38, the height of the silica gel arc plate 47 is stable, so that the downward movement of the scraper 38 removes the dye accumulated on the scraper 38 by the silica gel arc plate 47. Further, under the drive of the second assembly, the scraper 38 moves downward along the arc-shaped conductor 32 to make a downward concave parabolic trajectory, and during the movement of the scraper 38 from the left side to the right side of the arc-shaped conductor 32, the scraper 38 is attached to the silica gel arc plate 47 to move the silica gel arc plate 47. At this time, the extension rod 42 and the return spring 43 are compressed, and under the assistance of the moving wheel 45, the auxiliary block 44 moves from left to right in the positioning frame 41, which is matched with the movement trajectory of the scraper 38. After the subsequent cleaning is completed, the scraper 38 moves away from the third assembly, the silica gel arc plate 47 is separated from the scraper 38, the silica gel arc plate 47 is restored to the original position under the restoring force of the return spring 43, and the silica gel arc plate 47 returns to the standby state. This operation ensures the cleanliness of the scraper 38, avoids the residual dye on the scraper 38 from being attached to the conveying roller shaft 21 again to cause pollution during the cleaning of the conveying roller shaft 21.

[0056] Through the setting of the first assembly, in terms of lifting adjustment, the driving device 28 drives the gear 29 to mesh and transmit along the ring gear 24, the guide column 210 synchronously slides in the ring-shaped groove 23 to ensure transmission stability, the rotary motion of the gear 29 is converted into the up-down sliding of the sliding block 27 along the vertical guide groove 26, so that the second assembly as a whole realizes lifting. When the gear 29 meshes with the upper half tooth block of the ring gear 24, the scraper 38 rises to the attached state with the conveying roller shaft 21 to perform cleaning; when the gear 29 meshes with the lower half tooth block, the scraper 38 descends and separates, which facilitates the cleaning of the scraper 38. In terms of horizontal movement, the C-shaped clamping body 25 can slide horizontally along the fixed frame 22 to drive the second assembly as a whole to adjust the position, so as to ensure that the scraper 38 is adapted to the conveying roller shaft 21 of different lengths. Especially in the cleaning link of the scraper 38, the downward separation design makes the scraper 38 completely separate from the conveying roller shaft 21, avoids the incomplete cleaning of the scraper 38 at the position of the outer arc surface of the conveying roller shaft 21, and provides sufficient operation space for the silica gel arc plate 47 to clean the scraper 38.

[0057] Through the adaptive design of the second assembly and the conveying roller shaft 21, efficient cleaning of the dye on the surface of the roller shaft is achieved. On the one hand, the scraper 38 is made of silica gel material, the side arc surface close to the conveying roller shaft 21 is precisely adapted to the outer arc of the conveying roller shaft 21, and is arranged in an inclined state, which greatly improves the adhesion to the surface of the roller shaft, ensures that the cleaning surface covers the entire outer arc surface of the roller shaft, and avoids the generation of cleaning blind area due to poor adhesion. On the other hand, the cleaning action is linked with the rotation of the conveying roller shaft 21, and on the basis of the adhesion of the scraper 38 to the roller shaft, the continuous rotation of the conveying roller shaft 21 enables the scraper 38 to clean the circumferential surface of the roller shaft in all directions. Through this design, the residual dye on the surface of the conveying roller shaft 21 is effectively removed, avoiding the problem of residual dye contaminating the subsequent processing fabric 13 from the source, and preventing the change of the friction coefficient of the roller shaft caused by the adhesion of the dye, thereby ensuring the stability of the fabric conveying and improving the product qualification rate of the flat-cut fabric dyeing process.

[0058] Through the cooperation of the first assembly and the second assembly, the meshing movement of the first assembly gear 29 around the ring gear 24 controls the radial reciprocating movement of the second assembly on the outer ring of the conveying roller shaft 21. The scraper 38 in the second assembly further realizes the arc trajectory swing of the scraper 38 around the conveying roller shaft 21 under the setting of the arc-shaped conductor 32. Under the rotation of the conveying roller shaft 21 and the opposite rotation of the scraper 38, the reverse force and the composite motion trajectory are superimposed, the scraper 38 can form multi-directional peeling force on the stubborn dye residue on the surface of the roller shaft, significantly improve the thoroughness of cleaning, and avoid the difficulty of removing stubborn residues in a single cleaning direction.

[0059] Through the linkage work of multiple assemblies, when the scraper 38 moves to the side of the third assembly with the second assembly, the inner arc surface thereof is attached to the outer arc surface of the silica gel arc plate 47 of the third assembly. Under the control of the auxiliary system 14, the second assembly drives the scraper 38 to move downward, and since the silica gel arc plate 47 is fixed in height, the scraper 38 can form a reverse scraping force on the dye impurities accumulated on its cleaning surface during the downward movement. At the same time, when the scraper 38 moves along the concave parabolic trajectory of the arc-shaped conductor 32, it will push the silica gel arc plate 47 to slide along the positioning frame 41 with the auxiliary block 44, and the return spring 43 outside the telescopic rod 42 will be compressed synchronously, ensuring that the silica gel arc plate 47 is always attached to the scraper 38. After cleaning, the elastic force of the return spring 43 is released to reset the silica gel arc plate 47. The synchronous operation of the cleaning function and the self-cleaning function of the scraper 38 is realized, avoiding the re-attachment of the dye impurities remaining on the scraper 38 to the surface of the conveying roller shaft 21 or the processing fabric 13 in the subsequent cleaning process, forming a closed-loop cleaning mechanism of “cleaning-self-cleaning-re-cleaning”.
