Description

Technical Field

[0001] This utility model relates to the field of fiber fabric technology, and in particular to a fabric winding and unwinding device. Background Technology

[0002] The process of applying a setting agent to fiber fabrics involves unwinding and rewinding the fabric. A setting agent application device is set between unwinding and rewinding to spread and lay the setting agent on the fabric.

[0003] In practical operation, taking unwinding as an example, the operator usually fixes the material roll on the feeding shaft, manually aligns it, adjusts the resistance of the damping device, and then passes the material through the guide shaft into the subsequent main equipment. Existing unwinding devices are prone to tension fluctuations in the fabric due to mechanical assembly errors and positional deviations between guide rollers, and may even cause the material to deviate from its intended path. On the other hand, the fabric has a long backward conveying path, and even a slight tilt in the conveying direction will directly lead to an increase in the scrap rate. For the winding device, the tilt of the fabric will directly lead to irregular winding and reduced quality. Utility Model Content

[0004] To address the aforementioned issues, this application provides a fabric winding and unwinding device with a reasonable structure, thereby enabling timely and proactive correction and effectively ensuring the straight winding and unwinding motion of the fabric.

[0005] The technical solution adopted in this utility model is as follows: A fabric take-up and unwinding device includes a base, on which a movable bracket and a fixed bracket are respectively installed in the front-to-back direction. The movable bracket is driven by a translation mechanism to move in the left-to-right direction relative to the base. A parallel air shaft and a guide roller are rotatably installed on the movable bracket in the front-to-back direction. A transition roller one, a tension roller, and a transition roller two are rotatably installed on the fixed bracket in the front-to-back direction. A correction sensor is also installed on the fixed bracket. The correction sensor is located at the left or right edge of the fabric and detects the edge line of the fabric.

[0006] As a further improvement to the above technical solution: The translation mechanism has the following structure: it includes a driving power installed on the base, the output end of which is connected to the bottom surface of the movable support, and multiple sets of guide rail slider assemblies are installed between the movable support and the base; the driving power outputs linear driving power in the left and right directions.

[0007] The drive power is rotatably mounted with support one and support two at both ends. Support one is mounted on the bottom surface of the movable bracket, and support two is mounted on the base. The guide rail slider assembly is provided in four sets, which are arranged at the four corners of the movable bracket.

[0008] The fixed bracket is equipped with an extension frame facing the movable bracket. A circular tube arranged axially in the left-right direction is installed on the side of the extension frame. A support frame is circumferentially fitted on the circular tube, and a correction sensor is installed on the support frame. The support frame is locked with fasteners after moving along the axial direction of the circular tube.

[0009] The correction sensor has a U-shaped structure facing the edge of the fabric, and the fabric edge thread passes through the inside of the U-shaped structure.

[0010] Safety chucks are installed at both ends of the air expansion shaft located inside the movable support. The safety chucks, in conjunction with the air expansion shaft, fix the material roll.

[0011] A magnetic powder brake is installed at the end of the air shaft. The magnetic powder brake adjusts the output torque so that the tension value of the fabric winding and unwinding is consistent with the set value.

[0012] The tension roller is mounted on a fixed bracket with its two ends supported by support seats, and a tension sensor is installed at the end of the tension roller located outside the support seat.

[0013] The tension roller and the axes of the two transition rollers (first and second) are located at the same height.

[0014] A photoelectric sensor is installed on the inner bottom surface of the movable support, with the photoelectric sensor facing the fabric.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model has a compact and reasonable structure and is easy to operate. Through the real-time detection and feedback of the fabric edge by the correction sensor, the movable bracket is driven by the translation mechanism to move in the left and right directions relative to the base to make corresponding adjustments, thereby realizing timely and active correction and effectively ensuring the straight winding and unwinding movement of the fabric. This utility model also has the following advantages: A correction sensor is used to detect the position of the fabric edge, and a translation mechanism adjusts the position of the movable support in the left and right directions to correct the serpentine deviation of the fabric in a timely manner and ensure linear movement. The fabric roll is fixed on the air expansion shaft, and the fabric is passively unwound. The magnetic powder brake adjusts the output torque in real time according to the data fed back by the tension sensor to ensure that the tension of the fabric is consistent with the set value when it is unwound. The correction sensor is mounted on the extension frame of the fixed bracket via a support frame and a round tube. The width can be matched according to the actual width of the fabric by adjusting the support frame along the length of the round tube. Attached Figure Description

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, a fabric take-up and unwinding device according to this embodiment includes a base 1. A movable bracket 11 and a fixed bracket 12 are respectively installed on the base 1 in the front-back direction. The movable bracket 11 is driven by a translation mechanism to move in the left-right direction relative to the base 1. A parallel air shaft and a guide roller 4 are rotatably installed on the movable bracket 11 in the front-back direction. A transition roller 5, a tension roller 6, and a transition roller 7 are rotatably installed on the fixed bracket 12 in the front-back direction. A correction sensor 8 is also installed on the fixed bracket 12. The correction sensor 8 is located at the left or right edge of the fabric 20 and detects the edge line of the fabric 20.

[0023] In this embodiment, the real-time detection and feedback of the edge of the fabric 20 by the correction sensor 8 is used to drive the movable bracket 11 to move in the left and right directions relative to the base 1 for corresponding adjustment, thereby realizing timely and active correction.

[0024] In this embodiment, a correction sensor 8 is used to detect the position of the edge of the fabric 20, and a translation mechanism is used to adjust the position of the movable support 11 in the left and right directions to correct the serpentine deviation of the fabric 20 in a timely manner and ensure linear movement.

[0025] like Figure 3As shown, the translation mechanism has the following structure: it includes a driving power 81 mounted on the base 1, the output end of the driving power 81 is connected to the bottom surface of the movable bracket 11, and multiple sets of guide rail slider assemblies 84 are installed between the movable bracket 11 and the base 1; the driving power 81 outputs linear driving power in the left and right directions.

[0026] In this embodiment, when it is necessary to adjust the movable bracket 11 in the left and right directions, the driving power 81 works, driving the movable bracket 11 to move and adjust in the left and right directions relative to the base 1 with the guide rail slider assembly 84 as the guide.

[0027] In this embodiment, the driving power 81 can be a conventional standard component that outputs linear driving power, such as a cylinder, hydraulic cylinder, or electric cylinder.

[0028] The drive power 81 has two supports 82 and 83 mounted on its two ends respectively. Support 82 is mounted on the bottom surface of the movable bracket 11, and support 83 is mounted on the base 1. The guide rail slider assembly 84 is provided in four sets, which are arranged at the four corners of the movable bracket 11.

[0029] In this embodiment, by hinged installation of the two sections of the driving power 81, the smooth and unobstructed movement of the movable bracket 11 driven by the driving power 81 is effectively ensured.

[0030] like Figure 4 As shown, an extension frame 13 is installed on the fixed bracket 12 facing the movable bracket 11. A circular tube 85 is installed on the side of the extension frame 13 and is arranged axially in the left and right direction. A support frame 86 is circumferentially fitted on the circular tube 85. A correction sensor 8 is installed on the support frame 86. After the support frame 86 moves along the axial direction of the circular tube 85, it is locked with fasteners.

[0031] In this embodiment, the correction sensor 8 is mounted on the extension frame 13 of the fixed bracket 12 via the support frame 86 and the round tube 85. The width can be matched according to the actual width of the fabric 20 by adjusting the support frame 86 in the length direction of the round tube 85.

[0032] The correction sensor 8 has a U-shaped structure facing the edge of the fabric 20, and the edge of the fabric 20 is inserted inside the U-shaped structure, which effectively ensures the reliability and stability of the detection of the edge of the fabric 20.

[0033] Safety chucks are installed at both ends of the air expansion shaft located inside the movable bracket 11. The safety chucks, in conjunction with the air expansion shaft, fix the material roll 10, thereby achieving and ensuring the reliable installation of the material roll 10.

[0034] A magnetic powder brake 3 is installed at the end of the air shaft. The magnetic powder brake 3 adjusts the output torque so that the tension value of the fabric 20 during winding and unwinding is consistent with the set value.

[0035] In this embodiment, according to actual needs, scale lines can be set on the surface of the air expansion shaft along the length direction to meet the initial positioning of material rolls 10 with different widths.

[0036] When used as an unwinding device, this embodiment is passively unwinding, with torque adjustment combined with the magnetic powder brake 3; when used as a winding device, it can be actively winding, with a motor or other winding power installed at the end of the air shaft, and the tension is adapted by adjusting the torque and speed of the motor.

[0037] The tension roller 6 is mounted on the fixed bracket 12 with its two ends supported by support seats. The tension roller 6 ends located on the outside of the support seats are equipped with tension sensors 61.

[0038] In this embodiment, during actual use, the material roll 10 is fixed on the air expansion shaft, and the fabric 20 is passively unwound. The magnetic powder brake 3 adjusts the output torque in real time according to the data fed back by the tension sensor 61 to ensure that the tension of the fabric 20 is consistent with the set value when it is unwound.

[0039] The axis of tension roller 6 is located at the same height as the axis of transition roller 5 and transition roller 7 on both sides.

[0040] In this embodiment, tension roller 6 and transition roller 1 5 and transition roller 2 7 are all passive rotating rollers. Fabric 20 passes through transition roller 1 5, tension roller 6 and transition roller 2 7 in sequence to form a wrap angle. During the conveying of fabric 20, the tension of fabric 20 can be detected by tension sensor 61 at the end of tension roller 6.

[0041] In this embodiment, by setting the axes of tension roller 6, transition roller 1 5, and transition roller 2 7 at the same height, the tension detection point is located directly above the contact surface of tension sensor 61 at the end of tension roller 6, consistent with the fabric tension, ensuring that the detection matches the actual tension.

[0042] A photoelectric sensor 2 is installed on the inner bottom surface of the movable bracket 11, and the photoelectric sensor 2 is positioned facing the fabric 20.

[0043] In this embodiment, when the fabric 20 cannot be detected by the photoelectric sensor 2, it is determined that the fabric 20 is used up, and manual intervention or replacement can be provided through means such as flashing lights or beeping.

[0044] In this embodiment, the fabric winding and unwinding device uses a magnetic powder brake 3 at the end of the air shaft combined with a tension sensor 61 at the end of the tension roller 6 to achieve constant tension during the conveying of the fabric 20; the movable bracket 11 on the base 1 is set up with a translation mechanism combined with a correction sensor 8 to achieve active and timely correction during the conveying of the fabric 20.

[0045] This invention enables timely and proactive correction, effectively ensuring the straight-line winding and unwinding motion of the fabric.

[0046] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
