Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to an anti-tangling guide fabric mechanism for denim dyeing. Background Technology

[0002] The anti-tangling guide fabric mechanism for denim dyeing is a functional auxiliary equipment mechanism in the field of textile printing and dyeing technology (or denim fabric processing technology) that is specifically adapted to the denim dyeing production scenario. During the dyeing process of denim fabric using dyeing equipment (such as dyeing vats and pad dyeing machines), specific structural designs (such as guide roller sets, tension adjustment components, anti-deviation positioning components, and combing components) guide the denim fabric to maintain a stable conveying path. This prevents problems such as entanglement, knotting, wrinkling, or deviation caused by the fabric's own weight, tension changes, friction with equipment components, or overlapping of adjacent fabrics during high-speed transport, soaking and dyeing, or squeezing and dehydration. This ensures a continuous and smooth denim dyeing process, reduces production interruptions, fabric loss, and uneven dyeing (such as localized missed dyeing or color variations) caused by entanglement, ultimately guaranteeing the efficiency and quality of denim dyeing and providing consistently high-quality dyed fabric for subsequent denim garment processing. Operators have to go through tedious steps such as removing multiple fixing bolts and disassembling surrounding related components (such as bearing seats and protective covers) to remove the old rollers. The entire replacement process takes a long time (usually tens of minutes or even longer), which not only forces the dyeing production line to shut down for a long time and reduces the overall production efficiency, but also proposes an anti-tangling guide cloth mechanism for denim dyeing to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an anti-tangling guide fabric mechanism for denim dyeing, which aims to improve the problem that operators in the prior art need to go through cumbersome steps such as disassembling multiple fixing bolts and dismantling surrounding related components (such as bearing seats and protective covers) to remove the old rollers, and the whole replacement process is time-consuming.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A denim dyeing anti-tangle guiding mechanism includes a fixed wall, a replacement mechanism fixedly connected to the outside of the fixed wall, an alignment mechanism fixedly connected to the outside of the fixed wall, a buffer mechanism fixedly connected to the outside of the fixed wall, and a base plate fixedly connected to the bottom of the fixed wall. The replacement mechanism includes a motor 1, which is externally and fixedly connected to the inside of the fixed wall. A turntable is fixedly connected to the drive end of the motor 1. Two motors 2 are fixedly connected inside the turntable. A rotating rod is fixedly connected to the drive end of the motor 2. A pneumatic cylinder is fixedly connected inside the rotating rod. A connecting block is fixedly connected to the drive end of the pneumatic cylinder. A slip ring is fixedly connected to the outside of the connecting block. Multiple fixed blocks are fixedly connected to the outside of the slip ring. Two follower plates are rotatably connected to the outside of the fixed blocks. A limiting component is rotatably connected to the other end of the follower plate. As a further description of the above technical solution: The calibration mechanism includes a mounting plate, which is fixedly connected to the outside of the fixed wall. Multiple protective covers are fixedly connected to the bottom of the mounting plate, and multiple buffer columns are fixedly connected to the bottom of the mounting plate. A spring is sleeved on the outside of each buffer column. As a further description of the above technical solution: A limiting block is fixedly connected to the bottom of the buffer column, one end of the buffer column is fixedly connected to the bottom of the mounting plate, and the bottom end is fixedly connected to the top of the limiting block. As a further description of the above technical solution: The bottom of the protective cover is fixedly connected to the top of the limiting block, and two sensors are fixedly connected to the bottom of the mounting plate; As a further description of the above technical solution: The limiting component includes a limiting plate, the bottom of which is rotatably connected to the outside of the follower plate, and a protective shell is movably connected to the outside of the limiting plate; As a further description of the above technical solution: The buffer mechanism includes a fixed plate, which is fixedly connected to the outside of the fixed wall. A slide rail is fixedly connected to the outside of the fixed plate, a slider is slidably connected to the outside of the slide rail, and a buffer roller is fixedly connected to the outside of the slider. As a further description of the above technical solution: The fixed plate is externally fixedly connected to two connecting posts, and the connecting posts are externally fixedly connected to a second spring. The other end of the second spring is fixedly connected to the top of the slider. As a further description of the above technical solution: The turntable is rotatably connected to the outside of the fixed wall, and the fixed wall is rotatably connected to a connecting roller.

[0005] This utility model has the following beneficial effects: 1. In this utility model, the pneumatic cylinder pushes the connecting block to move, which in turn moves the slip ring and the fixing block. The fixing block pulls the follower plate to adjust the angle, so that the limiting component locks and fixes the protective shell to adapt to different specifications. The second motor drives the protective shell to rotate and rewind through the rotating rod. In the buffer mechanism, the buffer roller slides along the slide rail according to the tension of the fabric, and works with the second spring to buffer the tension, ensuring smooth rewinding and preventing tangling.

[0006] 2. In this utility model, after the denim fabric is dyed, it will be wound around the outside of the protective shell and rolled up. As the winding thickness increases, the fabric squeezes the limiting block, causing it to move up along the buffer column. At the same time, the first spring is compressed, and the protective cover moves up to protect the internal components. When the limiting block squeezes the sensor, the sensor triggers a signal, starting the first motor to drive the turntable to rotate, turning out the fully rolled protective shell and turning the unloaded protective shell into the working position, completing the automatic replacement.

[0009] 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.

[0010] Reference Figures 1 to 3 This utility model provides an embodiment of an anti-winding fabric guiding mechanism for denim dyeing, comprising a fixed wall 1, with a replacement mechanism 2 fixedly connected to the outside of the fixed wall 1, significantly reducing downtime; a calibration mechanism 3 fixedly connected to the outside of the fixed wall 1, capable of sensing the fabric winding thickness in real time to ensure accurate replacement timing; a buffer mechanism 5 fixedly connected to the outside of the fixed wall 1 to buffer the fabric conveying tension, preventing the fabric from becoming loose or stretched due to tension fluctuations; and a base plate 6 fixedly connected to the bottom of the fixed wall 1 to support the overall structure, enhancing the overall stability of the mechanism and preventing the equipment from tipping over during dyeing production. The replacement mechanism 2 includes a motor 21 as the power source for the replacement action. The motor 21 is externally fixedly connected to the inside of the fixed wall 1. The enclosed structure of the fixed wall 1 protects the motor 21 from the corrosion of dye and moisture in the dyeing environment, extending its service life. The drive end of the motor 21 is fixedly connected to a turntable 22 for switching work positions. When a replacement signal is received, the motor 21 can drive the turntable 22 to rotate precisely, turning out the protective shell 292 wrapped with fabric and turning the unloaded protective shell 292 into the work position, without the need for manual disassembly and replacement. The turntable 22 has two internal fixed connections for protection. The protective shell 292 is powered by a second motor 210, which rotates synchronously with the turntable 22 to ensure that the protective shells 292 at different work positions can obtain stable power. The drive end of the second motor 210 is fixedly connected to a rotating rod 23 that transmits power, which can transmit the torque of the second motor 210 to the protective shell 292, driving the protective shell 292 to rotate at a uniform speed, ensuring that the denim fabric is neatly arranged when wrapped, and reducing the risk of tangling. The rotating rod 23 is fixedly connected to a pneumatic cylinder 24 for adjusting the position of the limiting component 29. The pneumatic drive method has the characteristics of fast response and stable thrust, which can ensure that the adjustment action is precise and controllable.

[0011] The drive end of the pneumatic cylinder 24 is fixedly connected to a power transmission block 25, which can transmit the linear power of the pneumatic cylinder 24 to the subsequent components, realizing the effective transmission of force. The external of the connection block 25 is fixedly connected to a synchronously moving slip ring 26, which can move synchronously and linearly with the connection block 25, providing a unified moving base for multiple fixed blocks 27. The external of the slip ring 26 is fixedly connected to multiple evenly distributed fixed blocks 27, which can ensure that the force at each point is consistent when the follower plate 28 is pulled, and avoid the deformation of the follower plate 28 due to uneven force. The external of the fixed block 27 is rotatably connected to two follower plates 28 with flexible adjustable angles. By rotating, the angle can be changed to adapt to the support requirements of protective shells 292 of different diameters. The other end of the follower plate 28 is rotatably connected to a limiting component 29 for limiting and fixing the protective shell 292. The position can be adjusted by pulling the follower plate 28, ensuring that the protective shell 292 does not shift or shake when rotating and winding. The limiting component 29 includes a limiting plate 291 that provides support and limit. The bottom of the limiting plate 291 is rotatably connected to the outside of the follower plate 28. It can adjust its position according to the angle of the follower plate 28 to adapt to different specifications of protective shells 292. The outside of the limiting plate 291 is movably connected to a protective shell 292 that serves as a fabric wrapping carrier. The shell 292 has a smooth surface and a stable structure, which can ensure that the denim fabric is neatly arranged when wrapped, effectively preventing the fabric from getting tangled and wrinkled. At the same time, the movable connection method facilitates quick replacement. The buffer mechanism 5 includes a fixed plate 51 that serves as the mounting base for the buffer components. The fixed plate 51 is externally fixedly connected to the outside of the fixed wall 1, ensuring that components such as the slide rail 54 are securely installed. The fixed plate 51 is externally fixedly connected to a slide rail 54 that provides guidance for the slider 55, which restricts the slider 55 to slide only in the vertical direction and prevents the position of the buffer roller 56 from shifting. The slide rail 54 is externally slidably connected to a slider 55 that drives the buffer roller 56 to move, which can adjust the height of the buffer roller 56 according to the changes in fabric tension. The slider 55 is externally fixedly connected to a buffer roller 56 that directly contacts the fabric, which can guide the fabric direction by rotating itself, and at the same time, cooperate with the movement of the slider 55 to buffer tension fluctuations, preventing the fabric from becoming loose, tangled, or stretched and deformed due to unstable tension. Reference Figure 1 , Figure 2 and Figure 4 The calibration mechanism 3 includes a mounting plate 31 that serves as a carrier for mounting calibration components. The mounting plate 31 is fixedly connected to the outside of the fixed wall 1, providing a stable mounting position for components such as protective covers 32 and buffer columns 33. Multiple protective covers 32 that protect internal components are fixedly connected to the bottom of the mounting plate 31, preventing dye residue and fabric fibers from adhering to the buffer columns 33 and springs 34 during the dyeing process, thus avoiding component jamming and affecting the buffering effect. Multiple buffer columns 33 that provide guidance for the limiting block 35 are fixedly connected to the bottom of the mounting plate 31, ensuring that the limiting block 35 moves only in the vertical direction, avoiding deviation that could lead to monitoring errors. Springs 34 with elastic buffering function are sleeved on the outside of the buffer columns 33, which can absorb the impact force of the limiting block 35 through extension and retraction, preventing it from directly hitting the mounting plate 31 or the sensor 36. The bottom of the buffer column 33 is fixedly connected to a limiting block 35 that directly senses the thickness of the fabric wrapping. As the thickness of the denim fabric wrapping outside the protective shell 292 increases, the limiting block 35 will be squeezed by the fabric and move upward along the buffer column 33, providing real-time feedback on the wrapping status. One end of the spring 34 is fixedly connected to the bottom of the mounting plate 31, and the bottom of the spring 34 is fixedly connected to the top of the limiting block 35. When the limiting block 35 moves upward, the spring 34 is compressed and generates a reverse elastic force, which both buffers the moving speed of the limiting block 35 and keeps it in contact with the fabric surface, ensuring the accuracy of thickness monitoring. The bottom of the protective cover 32 is fixedly connected to the top of the limiting block 35 and can move up and down synchronously with the limiting block 35, always enclosing the buffer column 33 and spring 34, continuously isolating external impurities. The bottom of the mounting plate 31 is fixedly connected to two sensors 36 that trigger replacement signals. When the limiting block 35 moves up to the squeezing sensor 36 due to excessive fabric wrapping, the sensor 36 will immediately send a signal to start the motor 21, realizing automatic triggering of the replacement action without manual monitoring. Reference Figure 1 and Figure 4 The fixed plate 51 has two connecting posts 52 that provide fixed ends for the second spring 53. The symmetrically distributed connecting posts 52 ensure that the second spring 53 is subjected to balanced forces. The connecting posts 52 are externally fixed with the second spring 53, which provides elastic buffering force. The second spring 53 can generate a reverse force through extension and contraction to counteract the fluctuation of fabric tension. The other end of the second spring 53 is fixedly connected to the top of the slider 55. When the fabric tension increases and drives the buffer roller 56 and the slider 55 to move upward, the second spring 53 stretches to generate tension to buffer the tension. When the tension decreases, the second spring 53 contracts and drives the buffer roller 56 to move downward, maintaining the stability of the fabric tension. The turntable 22 is externally rotatably connected to the outside of the fixed wall 1. The fixed wall 1 provides radial support for the turntable 22, preventing it from jamming due to uneven force during rotation and ensuring smooth switching of work positions. The fixed wall 1 is externally rotatably connected to a connecting roller 4 that guides the fabric conveying. This roller can smoothly guide the dyed denim to the protective shell 292, preventing the fabric conveying path from deviating and causing friction with other components, reducing fabric wear, and ensuring flatness during winding, thus helping to improve the anti-winding effect.

[0012] Working principle: During the winding process after denim dyeing, the fabric is wrapped around the outside of the protective shell 292. As the winding thickness increases, the fabric will press upward against the limiting block 35. When the limiting block 35 moves upward along the buffer column 33, it compresses the spring 34 sleeved on the outside of the buffer column 33. The protective cover 32 moves synchronously with the limiting block 35 to isolate dye impurities and protect the buffer column 33 and the spring 34. When the limiting block 35 moves upward to the compression sensor 36, the sensor 36 triggers a signal, starting the motor 21 to drive the turntable 22 to rotate, rotating the fully wound protective shell 292 out of the working position and simultaneously rotating the empty protective shell 292 in, realizing automatic replacement.

[0013] After replacement, the pneumatic cylinder 24 is activated to push the connecting block 25 to move, which in turn drives the slip ring 26 and the fixing block 27 to move synchronously. The fixing block 27 pulls the follower plate 28 to adjust the angle, so that the limiting component 29 precisely engages with the protective shell 292 to meet the fixing requirements of different specifications of protective shell 292. The motor 210 drives the protective shell 292 to rotate and rewind through the rotating rod 23. The buffer roller 56 in the buffer mechanism 5 slides along the slide rail 54 through the slider 55 as the fabric tension changes, and works with the spring 53 to buffer tension fluctuations, ensuring smooth rewinding and avoiding tangling.
