Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, specifically a winding device for denim fabric production. Background Technology

[0002] Due to its thickness and abrasion resistance, denim fabric requires high-precision winding devices in textile processing to achieve uniform winding, thus avoiding material waste in subsequent slitting processes caused by tapered winding (thicker in the middle and thinner at the edges) or fabric wrinkles. Traditional winding devices have the following drawbacks:

[0003] Low workstation switching efficiency: After a single-axis winding is completed, the machine needs to be stopped and the winding needs to be manually replaced, which is time-consuming and can easily introduce fluctuations in fabric tension.

[0004] Poor axial adjustment accuracy: Relying on mechanical cams or fixed tracks to achieve fabric distribution, it is impossible to dynamically compensate for fabric deviation, resulting in insufficient flatness of the roll end face.

[0005] To address the aforementioned issues, this invention proposes a denim fabric winding device that integrates rapid station switching and high-precision axial adjustment. Through modular design, it enables multi-station collaborative operation while optimizing the transmission structure to improve the uniformity of fabric distribution. Utility Model Content

[0007] To achieve the above objectives, the present invention provides the following technical solution: a winding device for denim fabric production, comprising a winding machine cabinet for providing driving power for a winding motor, a winding motor fixedly installed on the top of the winding machine cabinet, and an air-expanding winding shaft slidably installed at the output end of the winding motor. A support base plate is provided at the bottom of the winding machine cabinet near the air-expanding winding shaft, and support side plates and support columns for supporting the air-expanding winding shaft are fixedly installed on both sides of the top of the support base plate, respectively.

[0008] The bottom of the winding machine cabinet near the air-expansion winding shaft is fixedly installed with a winding station switching mechanism, which is used to change the front and rear positions of the support base plate.

[0009] A winding axial adjustment mechanism is fixedly installed on the top of one side of the support column, and is used to adjust the axial position of the air-expansion winding shaft.

[0010] As a preferred embodiment of this utility model, the winding station switching mechanism includes a limiting base frame, which is fixedly installed at the bottom of the front and rear sides of the winding machine cabinet. A sliding rod is fixedly installed inside the limiting base frame, and a transverse sliding component is provided at the bottom of the supporting base plate. A sliding sleeve is slidably installed on the surface of the sliding rod.

[0011] As a preferred embodiment of this utility model, the transverse sliding component includes a limiting slide bar, and four sets of limiting slide bars are fixedly installed, with each of the four sets of limiting slide bars being fixedly installed with a sliding sleeve. The bottom of the supporting base plate is provided with a sliding groove that slides with the limiting slide bar. The top of the supporting base plate, on the side away from the winding machine cabinet, is threaded with positioning bolts on both sides, and the bottom of the positioning bolts is detachably installed with the limiting slide bar.

[0012] As a preferred embodiment of this utility model, the winding axial adjustment mechanism includes an adjustment box, a drive motor is fixedly installed on the back of the adjustment box, the output end of the drive motor passes through the interior of the adjustment box and is fixedly installed with a drive swing arm, a limit pin is fixedly installed at the bottom center of the back of the inner wall of the adjustment box, a swing adjustment arm is sleeved on the surface of the limit pin, the inside of the swing adjustment arm is slidably engaged with the output end of the drive swing arm, and the top of the swing adjustment arm is drivenly engaged with the end of the air expansion winding shaft away from the winding machine cabinet.

[0013] As a preferred embodiment of this utility model, a wave frame is fixedly installed at the bottom of the end of the air-expanding winding shaft away from the winding machine cabinet, a torsion shaft is fixedly installed at the top of the swing adjustment arm, and a sliding block is rotatably installed on the surface of the torsion shaft, with both sides of the sliding block slidingly engaging with the bottom of the wave frame.

[0014] As a preferred embodiment of this invention, the swing adjustment arm has an internal movable groove, which slides in conjunction with the output end of the drive swing arm.

[0015] As a preferred embodiment of this utility model, a pressure cover is detachably installed on the top of the support side plate, a pressure cover is detachably installed on the top of the support column, and the end of the air-expansion winding shaft near the winding motor is axially slidably connected to the output end of the winding motor.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model achieves high efficiency and precision in winding operations by setting up a winding station switching mechanism and a winding axial adjustment mechanism in synergy. In the winding station switching mechanism, when the roll reaches the set diameter, the PLC-controlled cylinder drives the sliding sleeve, causing the support base plate to move quickly from station A to station B along the sliding rod. After the positioning bolts are fixed in position, the air shaft can be easily replaced, significantly shortening the shaft replacement time and providing efficient assurance for continuous production. Simultaneously, the winding axial adjustment mechanism allows the drive motor to drive the swing arm to swing around the limit pin in a fan shape when the deviation sensor detects a deviation at the fabric edge. This swing is then converted into axial translation of the air shaft through the sliding block and the wave frame, promptly correcting the deviation problem. The combination of these two mechanisms not only improves continuous production efficiency but also ensures uniform fabric winding, avoiding uneven edges, wrinkles, and other problems, reducing waste in subsequent processes, and comprehensively improving the quality and efficiency of the winding operation.

[0018] 2. This utility model, by setting a winding station switching mechanism, includes a limiting base frame, a sliding rod, a sliding sleeve, a limiting slide bar, and positioning bolts. The limiting base frame securely limits the sliding rod, and the sliding sleeve can slide along the sliding rod and drive the support base plate to move through the transverse sliding component. When the roll reaches the set diameter, the PLC controls the cylinder to drive the sliding sleeve, so that the support base plate quickly moves from station A to station B. The positioning bolt is screwed into the positioning hole to fix the position. This structure realizes rapid station switching of the support base plate, avoiding the cumbersome operation of changing the air expansion shaft in traditional winding equipment, thereby greatly shortening the shaft changing time and improving the efficiency of continuous production.

[0019] 3. This utility model, by setting up a winding axial adjustment mechanism, consists of an adjustment box, a drive motor, a drive swing arm, a limit pin, and a swing adjustment arm. When the deviation sensor detects the fabric edge deviation, the PLC controls the drive motor to run, and the drive swing arm drives the swing adjustment arm to swing in a fan shape around the limit pin. Through the cooperation of the sliding block and the wave frame, this is converted into the axial translation of the air-expanding winding shaft. This mechanism can correct the fabric deviation problem in time, ensure that the fabric is evenly wound on the air-expanding winding shaft, and avoid uneven edges, wrinkles, etc., thereby ensuring the quality of winding and reducing waste for subsequent slitting and other processes.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0030] Reference Figure 1-5This is the first embodiment of the present invention, which provides a winding device for denim production, including a winding machine cabinet 1 for providing driving power for a winding motor 2, a winding motor 2 fixedly installed on the top of the winding machine cabinet 1, and an air-expanding winding shaft 21 slidably installed on the output end of the winding motor 2. A support base plate 3 is provided at the bottom of the winding machine cabinet 1 near the air-expanding winding shaft 21, and support side plates 31 and support columns 4 for supporting the air-expanding winding shaft 21 are fixedly installed on both sides of the top of the support base plate 3, respectively.

[0031] A winding station switching mechanism is fixedly installed at the bottom of the winding machine cabinet 1 near the air-expanding winding shaft 21, and is used to change the front and rear positions of the support base plate 3.

[0032] A winding axial adjustment mechanism is fixedly installed on the top of one side of the support column 4, and is used to adjust the axial position of the air expansion winding shaft 21.

[0033] The winding station switching mechanism includes a limiting base frame 6, which is fixedly installed at the bottom of the front and rear sides of the winding machine cabinet 1. A sliding rod 61 is fixedly installed inside the limiting base frame 6, and a transverse sliding component is provided at the bottom of the support base plate 3. A sliding sleeve 62 is slidably installed on the surface of the sliding rod 61. The limiting base frame 6 can limit the installation of the sliding rod 61. After the sliding rod 61 is installed, the sliding sleeve 62 can slide back and forth on the surface. Then, the transverse sliding component can drive the support base plate 3 to adjust the front and rear positions. After one roll of fabric is completed, a new roll can be quickly wound. The sliding sleeve 62 can be directly driven back and forth inside the sliding rod 61 by connecting to an external power source, such as a cylinder or electric push rod, thereby improving the switching speed of the air-expansion winding shaft 21.

[0034] The lateral sliding assembly includes four sets of limiting slide bars 63, each fixedly installed with a sliding sleeve 62. The bottom of the support base plate 3 has a groove for sliding engagement with the limiting slide bars 63. Positioning bolts 64 are threaded onto both sides of the top of the support base plate 3, away from the winding machine cabinet 1. The bottom of the positioning bolts 64 is detachably installed from the limiting slide bars 63. The limiting slide bars 63 allow the support base plate 3 to slide laterally on its surface. After winding, the positioning bolts 64 can be twisted to separate from the limiting slide bars 63, facilitating the sliding of the support base plate 3 on the limiting slide bars 63. This allows the support base plate 3 to drive the top support side plate 31 and support column 4 to move laterally, thereby driving the air-expanding winding shaft 21 away from the output end of the winding motor 2. This facilitates the front-to-back position switching of the support base plate 3, allowing for convenient switching between the wound air-expanding winding shaft 21 and the air-expanding winding shaft 21 awaiting winding.

[0035] The winding axial adjustment mechanism includes an adjustment box 42. A drive motor 43 is fixedly installed on the back of the adjustment box 42. The output end of the drive motor 43 passes through the interior of the adjustment box 42 and is fixedly installed with a drive swing arm 431. A limit pin 432 is fixedly installed at the bottom center of the back of the inner wall of the adjustment box 42. A swing adjustment arm 433 is sleeved on the surface of the limit pin 432. The swing adjustment arm 433 slides with the output end of the drive swing arm 431. The top of the swing adjustment arm 433 is driven with the end of the air expansion winding shaft 21 away from the winding machine cabinet 1. The adjustment box 42 provides dust protection for the internal transmission structure, preventing personnel from interfering with the drive and ensuring the operational safety of surrounding personnel. After the drive motor 43 starts, it drives the drive swing arm 431 to rotate via its output end. The drive swing arm 431 then drives the swing adjustment arm 433 to twist around the axis of the limit pin 432, causing the swing adjustment arm 433 to be moved in a fan-shaped motion by the output end of the drive swing arm 431. Subsequently, through the transmission connection at the top with the air-expansion take-up shaft 21, the air-expansion take-up shaft 21 moves laterally following the top of the swing adjustment arm 433. This driving process is achieved using the drive motor 43 in conjunction with a deviation sensor installed on the take-up machine cabinet 1, ensuring the quality of the wound fabric and preventing excessive fabric protrusion at both ends of the air-expansion take-up shaft 21 after winding, which would affect the subsequent slitting quality and reduce waste after slitting.

[0036] A wave frame 437 is fixedly installed at the bottom of the end of the air-expanding take-up shaft 21 away from the take-up machine cabinet 1. A torsion shaft 435 is fixedly installed at the top of the swing adjustment arm 433. A sliding block 436 is rotatably mounted on the surface of the torsion shaft 435. The two sides of the sliding block 436 are slidably engaged with the bottom of the wave frame 437. Since the wave frame 437 is fixed to the air-expanding take-up shaft 21 and its bottom is slidably engaged with the sliding block 436, the swing adjustment arm 433 can move synchronously by moving the sliding block 436 through the torsion shaft 435 during the top fan-shaped movement. Furthermore, since the wave frame 437 is slidably engaged with the sliding block 436, it can be moved laterally by the sliding block 436 to achieve lateral adjustment of the air-expanding take-up shaft 21.

[0037] The swing adjustment arm 433 has an internal movable groove 434, which slides with the output end of the drive swing arm 431. The movable groove 434 allows the output end of the drive swing arm 431 to slide stably, reducing transmission backlash and ensuring the accuracy of lateral movement. At the same time, a bearing can be installed at the output end of the drive swing arm 431 to fit against the inner wall of the movable groove 434, ensuring reduced wear and improving the service life of the transmission structure.

[0038] A pressure cap 311 is detachably installed on the top of the support side plate 31, and a pressure cap 41 is detachably installed on the top of the support column 4. The installation of pressure cap 311 and pressure cap 41 facilitates the removal of the air expansion reel 21 by the operator after it is moved to the processing position, so as to remove the material and ensure the efficiency of unloading.

[0071] The air shaft 21 can be installed and removed by one hand by connecting it to the support side plate 31 / support column 4 with quick clamps (model CH-201).

[0072] Example 1: Textile Fabric Winding

[0073] On the production line of a textile factory, this winding equipment is used to wind up textile fabric. Initially, the support base plate 3 is in station A, close to the winding machine cabinet 1. The air shaft 21 is firmly connected to the output end of the winding motor 2 through a coupling. The operator tightly locks the first pressure cover 311 and the second pressure cover 41, and firmly fixes the end of the fabric to the surface of the air shaft 21.

[0074] During the winding process, the deviation sensor constantly monitors the edge position of the fabric. When the deviation of the fabric edge exceeds ±2mm, the PLC quickly outputs a pulse signal to the drive motor 43. After the drive motor 43 starts, it drives the drive swing arm 431 to move. The drive swing arm 431 then drives the swing adjustment arm 433 to swing around the limit pin 432 in a fan shape. The sliding block 436 at the top of the swing adjustment arm 433 slides and engages with the wave frame 437, cleverly converting the rotational motion into the axial translation of the air shaft 21. Its maximum stroke can reach ±150mm, thereby accurately controlling the distribution of the fabric and ensuring that the fabric is wound evenly.

[0075] In terms of tension control, the winding motor 2 is equipped with a frequency converter (model VFD007EL21A) for speed regulation. For fabric with a thickness of 0.5mm, the system automatically sets the linear speed to 50m / min. At the same time, the air pressure inside the air shaft 21 is precisely adjusted by a solenoid valve (model 4V210-08) to keep the friction between the fabric and the shaft surface constant. This ensures that the fabric will not be torn due to excessive tension or become loose due to insufficient tension during the winding process.

[0076] When the roll diameter reaches the set Φ800mm, the PLC issues a command to control the cylinder to push out. Under the push of the cylinder, the sliding sleeve 62 drives the support base plate 3 to move smoothly along the sliding rod 61 to station B. The operator then screws in the positioning bolt 64 to make it enter the positioning hole of the limit slide 63, firmly fixing the position of the support base plate 3. Then, the pressure cover 311 and pressure cover 41 are opened, the fully rolled air expansion shaft 21 is carefully removed and replaced with an empty shaft, and finally the pressure cover is reset. After these operations are completed, the cylinder is reset, and the support base plate 3 quickly returns to station A. The above steps of winding and switching stations are repeated again, realizing continuous and efficient winding production of textile fabrics.

[0077] Example 2: Nonwoven fabric winding

[0078] A nonwoven fabric manufacturer introduced this winding equipment for nonwoven fabric winding. Before the equipment was started, all components were in the initial state: the support base plate 3 was in place at station A, the air shaft 21 was correctly connected to the winding motor 2, the pressure cap 311 and pressure cap 41 were locked, and the end of the nonwoven fabric was fixed on the air shaft 21.

[0079] As winding begins, the deviation sensor attentively monitors the edge position of the nonwoven fabric. Once the edge position deviation exceeds ±2mm, the PLC responds immediately by sending a pulse signal to the drive motor 43. The drive motor 43 drives the drive arm 431, which in turn drives the swing adjustment arm 433 to swing around the limit pin 432. Through the cooperation of the sliding block 436 and the wave frame 437, the air shaft 21 achieves a maximum stroke of ±150mm axial translation, effectively correcting the deviation problem of the nonwoven fabric and ensuring its uniform winding.

[0080] For tension control of nonwoven fabric winding, the winding motor 2 uses a frequency converter (VFD007EL21A) to adjust the speed. Since the nonwoven fabric is relatively thin, when the thickness is 0.3mm, the system sets the linear speed to 40m / min. The internal air pressure of the air shaft 21 is precisely controlled by a solenoid valve (4V210-08) to maintain stable friction between the fabric and the shaft surface, so that the thin nonwoven fabric can be tightly and neatly wound on the air shaft.

[0081] When the roll reaches the set diameter Φ800mm, the PLC controls the cylinder to move, the support base plate 3 moves to station B, the positioning bolt 64 is fixed in position, the operator opens the pressure cover, replaces the air expansion shaft and resets the pressure cover, the cylinder resets, the support base plate 3 returns to station A, and continues a new round of winding operation, which meets the needs of non-woven fabric manufacturers for efficient and stable winding, and improves production efficiency and product quality.

[0082] 1. Initial state

[0083] The support base plate 3 is located at station A near the winding machine cabinet 1, and the air shaft 21 is connected to the output end of the winding motor 2 via a coupling.

[0084] The first pressure cap 311 and the second pressure cap 41 are locked together, and the end of the fabric is fixed to the surface of the air expansion shaft 21.

[0085] 2. Rewinding process

[0086] Fabric distribution control:

[0087] The fabric edge sensor detects the fabric edge position in real time. When the deviation exceeds ±2mm, the PLC outputs a pulse signal to drive motor 43.

[0088] Drive motor 43 drives swing adjustment arm 433 to swing around limit pin 432 in a fan shape via drive swing arm 431;

[0089] The top of the swing adjustment arm 433 slides with the wave frame 437 via the sliding block 436, converting the rotational motion into the axial translation of the air shaft 21 (maximum stroke ±150mm).

[0090] Tension control:

[0091] The winding motor 2 uses a frequency converter (model VFD007EL21A) for speed regulation, and the linear speed is linked to the fabric thickness (e.g., 50m / min for 0.5mm thick fabric).

[0092] The internal air pressure of the air shaft 21 is regulated by a solenoid valve (model 4V210-08) to maintain a constant friction between the fabric and the shaft surface.

[0093] 3. Workstation switching

[0094] When the roll diameter reaches the set value (e.g., Φ800mm):

[0095] The PLC controls the cylinder to extend, and the sliding sleeve 62 drives the support base plate 3 to move along the sliding rod 61 to station B;

[0096] The positioning bolt 64 is screwed into the positioning hole of the limiting slide bar 63 to fix the position of the support base plate 3;

[0097] The operator opens the pressure cover 311 and the pressure cover 41, removes the fully wound air expansion shaft 21, replaces the empty shaft, and then resets the pressure cover.

[0098] 4. Cyclic operation

[0099] The cylinder resets, and the support base plate 3 returns to station A. Steps 2-3 are repeated to achieve continuous production.
