Description

Technical Field

[0001] This utility model relates to the field of winding devices, and in particular to a winding machine with a flexible belt support mechanism having follow-up compensation. Background Technology

[0002] In the textile industry, as processes are constantly being innovated and customer demands are continuously increasing, the most common being the increase in fabric width, which leads to an increase in the length of the fabric winding roller. However, during the entire winding process, the fabric winding roller is only supported at both ends, and the middle part is prone to downward bending deformation under the influence of gravity and the weight of the fabric roll itself, which seriously affects the winding quality and the appearance of the finished fabric.

[0003] Several solutions to this problem already exist in the existing technology: A common practice is to add a rigid support plate or fixed support roller under the fabric roll roller to provide support through hard contact.

[0004] However, this type of rigid support structure has the following drawbacks: 1. Direct contact between the pallet or roller and the fabric surface can easily cause wear or indentation, affecting product quality; Second, as the diameter of the fabric roll continues to increase, the fixed-height support cannot move synchronously with the surface of the fabric roll, resulting in inconsistent support force and unstable performance. Third, rigid contact can also cause uneven compression of the paper tube inside the roll, leading to deformation of the paper tube.

[0005] Another existing solution uses an arc-shaped shaft structure, which makes the fabric roll itself slightly arc-shaped to counteract gravitational deflection through pre-deformation.

[0006] However, this method will cause the fabric roll to be uneven in tension in the width direction, resulting in a tight middle and loose sides, and uneven tension distribution inside the finished fabric roll, which will affect the smoothness of the subsequent unwinding process. Utility Model Content

[0007] To address the above problems, this utility model provides a winding machine with a flexible belt support mechanism that features follow-up compensation.

[0008] The utility model objective is achieved through the following solution: a winding machine with a flexible belt support mechanism for follow-up compensation, comprising a winding machine body, a friction roller, and a fabric roll. The friction roller is mounted on the winding machine body and rotates. The fabric roll is driven to rotate by the friction roller. A belt support mechanism is provided outside the winding machine body, which is attached to the fabric surface arc of the fabric roll by an annular belt to apply an upward flexible lifting force to the fabric roll, thereby counteracting the gravitational deflection of the middle of the fabric roll and preventing the fabric roll from bending. The fabric roll is pressed against the friction roller by rocker arms and forks located at the left and right ends of the fabric roll, and moves horizontally away from the friction roller as the diameter of the fabric roll increases. The two rocker arms and forks are hinged to the frame of the winding machine body by a pivot and swing synchronously around the pivot.

[0009] Furthermore, the upper end of the rocker arm swing fork is a U-shaped groove, and the left and right ends of the fabric rolling roller are placed in the corresponding U-shaped grooves.

[0010] Furthermore, the rocker arm fork is equipped with a reset rocker arm fork and a limit cylinder for limiting the rocker arm fork movement angle when it is too large near the friction roller.

[0011] Furthermore, the belt support mechanism includes a fixed rotating roller group, a movable rotating roller, a swing roller flipping mechanism, and an annular belt. The fixed rotating roller group is mounted below the friction roller via a mounting base. The movable rotating roller is positioned to the upper right of the fabric roll roller. The swing roller flipping mechanism is mounted on the side of the fabric roll roller away from the direction of movement of the friction roller via a ground mounting base. The annular belt is looped around the rotating roller, the movable rotating roller, and the rotating roller on the side of the support crossbar away from the fabric roll roller on the fixed rotating roller group. The outer side of the belt between the rotating roller and the movable rotating roller is attached to the outer surface of the fabric roll roller.

[0012] Furthermore, the two ends of the movable rotating roller are correspondingly set on the linear guide rails on both sides of the upper end of the winding machine body through the linear guide rail sliders. The movable rotating roller runs through the width of the fabric roll. The linear guide rail sliders are connected to the oil cylinders located behind the guide rails. The oil cylinders drive the movable rotating rollers to move back and forth in the horizontal direction.

[0013] Furthermore, at least one end of the pivot shaft of the rocker arm is provided with an angle sensor for detecting the real-time swing angle of the rocker arm; the controller is electrically connected to the angle sensor and receives the angle signal from the angle sensor; the proportional directional valve is provided in the oil supply line of the hydraulic cylinder that drives the movable rotating roller, and is electrically connected to the controller to control the action of the hydraulic cylinder according to the instructions of the controller.

[0014] Furthermore, each set of swing roller flipping mechanisms includes a support crossbar that swings up and down around a central axis on a ground-mounted base. Each end of the support crossbar is equipped with a rotating roller, which is driven to swing by a drive cylinder.

[0015] Advantages include: adaptive movement and continuous stable support: the rocker arm swing angle is detected in real time by the angle sensor, and the controller drives the hydraulic cylinder to automatically adjust the position of the movable rotating roller according to the angle signal, so that the movable rotating roller always maintains a constant distance from the fabric roll surface, providing effective lifting force throughout the process.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments: Unless otherwise specified, the experimental methods used in the following implementation examples are all conventional methods; the materials and reagents used are all commercially available unless otherwise specified.

[0023] Example 1, Appendix Figure 1-5A winding machine with a flexible belt support mechanism for follow-up compensation includes a winding machine body 1, a friction roller 4, and a fabric roll 2. The friction roller 4 is mounted on the winding machine body 1 and rotates. The fabric roll 2 is driven to rotate by the friction roller. A belt support mechanism 3 is provided outside the winding machine body 1 and is attached to the fabric surface arc of the fabric roll 2 by an annular belt 36. It applies an upward flexible lifting force to the fabric roll to counteract the gravitational deflection of the middle of the fabric roll and prevent the fabric roll from bending. The fabric roll 2 is pressed against the friction roller 4 by rocker arms and swing forks 5 set at the left and right ends of the fabric roll 2 and moves horizontally away from the friction roller 4 as the diameter of the fabric roll increases. The two rocker arms and swing forks 5 are hinged to the frame of the winding machine body 1 by a rotating shaft 51 and can swing synchronously around the rotating shaft 51.

[0024] Flexible support, no damage to the fabric surface: The use of ring belts to contact the fabric surface instead of rigid support plates or rollers, the belts are in flexible contact with the fabric surface, and the pressure is evenly distributed along the arc of the fabric surface, which will not cause scratches or indentations to the fabric surface, nor will it cause rigid compression damage to the paper tube inside the fabric roll; Support function: The three ring belts are inclined from the upper right to the lower left, and fit against the arc of the fabric surface of the fabric roll, applying a flexible lifting force to the fabric roll at an upward angle. The vertical upward component of this lifting force is used to counteract the gravitational deflection of the middle of the fabric roll and prevent the fabric roll from bending.

[0025] A winding machine with a flexible belt support mechanism for follow-up compensation, wherein the upper end of the rocker arm swing fork is a U-shaped groove, and the left and right ends of the winding roller 2 are placed in the corresponding U-shaped grooves.

[0026] Follow-up compensation function: As the winding process proceeds, the diameter of the fabric roll gradually increases, and the winding roller pushes the rocker arms at both ends to swing outward synchronously around their axis.

[0027] Angle sensor 6, located at the end of the pivot shaft of the rocker arm fork, detects the swing angle of the rocker arm fork in real time and transmits the angle signal to controller 7. Controller 7 has a preset correspondence between the swing angle of the rocker arm fork and the target position of the movable rotating roller 32. Controller 7 outputs a control signal to the proportional directional valve 8 based on this correspondence, driving the hydraulic cylinder 33 to push the movable rotating roller 32 to the corresponding target position, ensuring that the movable rotating roller 32 is always located above and to the right of the fabric roll 2 and maintains a constant distance from the fabric roll surface.

[0028] As the diameter of the fabric roll increases, the swing angle of the rocker arm 5 changes continuously. The angle sensor 6 detects this in real time, and the controller 7 updates the target position of the movable rotating roller 32 in real time, so that the movable rotating roller can follow the fabric roll surface in real time throughout the entire process.

[0029] The swing angle of the rocker arm fork 5 is obtained by the angle sensor 6, and the position of the rocker arm fork 5 that restricts the fabric roll is further known. The distance between the fabric roll and the friction roller is calculated, and then the diameter of the current fabric roll is inferred. Then, the rotating roller is driven to be located vertically directly above the fabric roll surface.

[0030] A winding machine with a flexible belt support mechanism for follow-up compensation, wherein the rocker arm fork is provided with a reset rocker arm fork and a limit cylinder for limiting the rocker arm fork movement angle when it is too large near the friction roller.

[0031] When the limit cylinder 52 is filled with air, the piston rod extends and the rocker arm swings clockwise around the rotating shaft 51; when the limit cylinder reverses direction, the piston rod retracts and the rocker arm swings counterclockwise around the rotating shaft 51. After the fabric roll has completed winding the entire fabric roll diameter, the fabric roll is removed from the winding machine. The rocker arm swing fork quickly returns to the starting position via the limit cylinder to ensure the positioning of the next fabric roll. When the fabric roll moves in the opposite direction to the friction roller through winding, the cylinder slowly intakes air so that the travel displacement generated by the rotation of the rocker arm swing fork is slightly less than the travel displacement generated by the fabric roll when winding the fabric, so as to ensure that the fabric roll can always be against the friction roller and have a certain pressure.

[0032] A winding machine with a flexible belt support mechanism for follow-up compensation, the belt support mechanism 3 includes a fixed rotating roller group 31, a movable rotating roller 32, a swing roller flipping mechanism 35 and an annular belt 36.

The tension is adjustable: the belt can be concentratedly tensioned and relaxed through a swing roller flipping mechanism, making operation simple and reliable.

[0036] Tensioning and slack functions: When the support bar 351 of the oscillating roller tilting mechanism 35 swings around the central axis, the rotating rollers at both ends of the support bar move up and down accordingly, changing the total length of the belt's winding path. When the support bar swings counterclockwise, the belt's winding path lengthens, and the belt is tensioned; when the support bar swings clockwise, the belt's winding path shortens, and the belt is relaxed.
