A winding machine for base fabric

Abstract

This application discloses a winding machine for base fabric, belonging to the field of base fabric winding technology. It includes a workbench and a control panel. A winding mechanism for winding the base fabric is fixedly installed on the upper surface of the workbench. This application uses the winding mechanism to wind the base fabric. A guide roller guides the base fabric along a path of "pressure roller - tension roller - pressure roller." A tension sensor and tension roller detect the tension experienced by the base fabric during winding in real time and send the tension data to the control panel. Based on the received tension data, the control panel controls the tension adjustment unit to make corresponding adjustments. A drive unit drives a threaded rod to rotate, causing the adjustment plate to move up and down inside the adjustment groove, thereby adjusting the height of the pressure roller.

Description

Technical Field

[0001] This application relates to the field of base fabric winding technology, and more particularly to a winding machine for base fabrics. Background Technology

[0002] The base fabric typically refers to the basic material that makes up the fabric, which can be various fiber materials such as cotton, linen, polyester, and nylon. The specific composition varies depending on the type of fabric. A winding machine is the material receiving part of a processing production line, mechanically winding raw materials into rolls. It is widely used in paper roll, fabric roll, plastic roll, and metal roll processing production lines.

[0003] During the operation of the winding machine, the base fabric may experience excessive or insufficient tension. If it is not adjusted in time, the unstable winding tension will lead to uneven tension distribution inside the fabric roll, resulting in wrinkles. This abnormal tension will directly affect the finished product quality and performance of the fabric roll. Therefore, an improvement has been made to a winding machine for base fabric. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a winding machine for base fabric, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a winding machine for base fabric, comprising a worktable and a control panel. A winding mechanism for winding the base fabric is fixedly installed on the upper surface of the worktable. A positioning seat is fixedly installed on one side of the upper surface of the worktable near the winding mechanism. Two tension sensors are symmetrically installed on the upper surface of the positioning seat, and a tension roller is disposed between the two tension sensors. A tension adjustment unit and a guide frame are symmetrically installed on both sides of the upper surface of the worktable near the tension roller. The guide frame is located outside the tension adjustment unit and is rotatably connected to a guide roller inside it. The tension adjustment unit includes a positioning frame fixedly installed on the upper surface of the worktable. Two adjustment grooves are symmetrically opened on the outer walls of both sides of the positioning frame. A threaded rod is rotatably connected inside the two adjustment grooves via bearings. A drive unit for driving the threaded rod to rotate is disposed on the top of the positioning frame. An adjustment plate is threadedly sleeved on the outer surface of the threaded rod inside the adjustment groove, and a crossbar is fixedly connected between the two adjustment plates. A pressure roller is rotatably sleeved on the outer surface of the crossbar.

[0006] By adopting the above technical solution, the base fabric is wound up by a winding mechanism, and the conveying direction of the base fabric is guided by guide rollers, so that the base fabric moves along the path of "pressure roller-tension roller-pressure roller". During the winding process, the tension sensor and tension roller work together to detect the tension of the base fabric in real time and send the tension data to the control panel. The control panel controls the tension adjustment unit to make corresponding adjustments based on the received tension data. The drive unit drives the threaded rod to rotate, so that the adjustment plate moves up and down inside the adjustment groove, thereby adjusting the height of the pressure roller located on the crossbar. This changes the winding tension of the base fabric, effectively ensuring the uniformity of the winding tension, preventing wrinkles in the fabric roll, and ultimately ensuring the quality of the product.

[0007] As a preferred embodiment of this application, the top of the tension roller and the guide roller are kept horizontally aligned, and the bottom of the pressure roller is lower than the bottom of the tension roller.

[0008] By adopting the above technical solution, the top of the tension roller and the guide roller are horizontally aligned to form a reference plane, ensuring that the fabric is horizontal when it enters the tension detection area, thus avoiding tension fluctuations caused by height differences. The design that the bottom of the pressure roller is lower than the tension roller allows the fabric path length to be changed by raising and lowering the pressure roller, thereby directly adjusting the winding tension.

[0009] As a preferred technical solution of this application, the drive unit includes a protective cover fixedly installed on the top of the positioning frame. Two transmission wheels are arranged in parallel inside the protective cover. The two transmission wheels are respectively sleeved on the outer surfaces of two threaded rods, and a transmission belt is provided between the two transmission wheels. A drive motor is fixedly installed on the top of the protective cover, and the output end of the drive motor is fixedly connected to the upper end of one of the threaded rods.

[0010] By adopting the above technical solution, the threaded rod connected to it is driven by a drive motor for transmission, and another threaded rod is driven to rotate synchronously through the transmission wheel and transmission belt.

[0011] As a preferred embodiment of this application, the length of the adjusting plate is the same as the length of the adjusting groove, and the width of the adjusting plate is the same as the width of the adjusting groove.

[0012] By adopting the above technical solution, the movement path of the adjusting plate is limited by the adjusting groove, ensuring that the adjusting plate can only move vertically along the axis of the threaded rod, avoiding deflection of the adjusting plate during movement, thereby ensuring the accuracy of the adjusting plate's movement.

[0013] As a preferred technical solution of this application, the winding mechanism includes a mounting frame fixedly installed on the surface of the workbench. A rotating shaft is rotatably connected inside the mounting frame. A winding motor that drives the rotating shaft to rotate is fixedly installed on the rear wall of the mounting frame. A fixing ring is fixedly connected to the outer wall of the rotating shaft near the mounting frame. A winding roller and a moving ring are slidably sleeved on the outer wall of the rotating shaft outside the fixing ring. A locking ring is threadedly sleeved on the outer wall of the rotating shaft outside the moving ring.

[0014] By adopting the above technical solution, the take-up roller is slidably sleeved on the rotating shaft, and together with the movable moving ring and locking ring, an adjustable clamping mechanism is formed to realize the installation of the take-up roller. When disassembling, simply loosen the locking ring to pull out the take-up roller axially. The rotating shaft is driven by the take-up motor to rotate, thereby driving the take-up roller to rotate for take-up work.

[0015] As a preferred technical solution of this application, both the fixed ring and the movable ring are fixedly connected to the outer wall of the side near the take-up roller with protrusions, and the outer walls of both sides of the take-up roller are symmetrically provided with grooves that are adapted to the protrusions, and the protrusions are slidably inserted into the grooves.

[0016] By adopting the above technical solution, the take-up roller is locked on the rotating shaft by sliding the protrusion into the groove, ensuring that the torque is transmitted to the take-up roller without loss and avoiding slippage during take-up.

[0017] As a preferred technical solution of this application, the tension sensor is signal-connected to the control panel, and the control panel is electrically connected to the drive motor via wires.

[0018] By adopting the above technical solution, the tension of the base fabric during the winding process is detected in real time by a tension sensor, and the tension data is sent to the control panel. The control panel dynamically adjusts the output of the drive motor according to the tension deviation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, the base fabric is wound up by a winding mechanism, and the conveying direction of the base fabric is guided by a guide roller, so that the base fabric moves along the path of "pressure roller-tension roller-pressure roller". During the winding process, the tension sensor and the tension roller work together to detect the tension of the base fabric in real time and send the tension data to the control panel. The control panel controls the tension adjustment unit to make corresponding adjustments based on the received tension data. The drive unit drives the threaded rod to rotate, so that the adjustment plate moves up and down inside the adjustment groove, thereby adjusting the height of the pressure roller located on the crossbar, and thus changing the winding tension of the base fabric. This effectively ensures the uniformity of the winding tension, prevents wrinkles in the fabric roll, and ultimately guarantees the quality of the product.

[0021] 2. In this utility model, the threaded rod connected to it is driven by a drive motor for transmission, and the two transmission wheels are transmitted through a transmission belt, so that the two threaded rods can rotate synchronously.

[0022] 3. In this utility model, the take-up roller is slidably sleeved on the rotating shaft. With the cooperation of the movable moving ring and the locking ring, the protrusion is slidably inserted into the groove, which can lock the take-up roller on the rotating shaft, realize the installation of the take-up roller, ensure that the torque is transmitted to the take-up roller without loss, and avoid the take-up roller slippage. When disassembling, simply loosen the locking ring to pull out the take-up roller axially. The take-up motor drives the rotating shaft to rotate, thereby driving the take-up roller to rotate for the take-up operation.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figure 1 - Figure 5As shown, this embodiment provides a winding machine for base fabric, including a workbench 1 and a control panel 9. A winding mechanism 2 for winding the base fabric is fixedly installed on the upper surface of the workbench 1. A positioning seat 3 is fixedly installed on one side of the winding mechanism 2 on the upper surface of the workbench 1. Two tension sensors 4 are symmetrically installed on the upper surface of the positioning seat 3, and a tension roller 5 is disposed between the two tension sensors 4. A tension adjusting unit 6 and a guide frame 7 are symmetrically installed on both sides of the tension roller 5 on the upper surface of the workbench 1. The guide frame 7 is located outside the tension adjusting unit 6, and a guide roller 8 is rotatably connected inside it. The tension adjusting unit 6 includes a positioning frame 61 fixedly installed on the upper surface of the workbench 1. Two adjusting grooves 62 are symmetrically opened on the outer walls of both sides of the positioning frame 61. A threaded rod 64 is rotatably connected inside each of the two adjusting grooves 62 via a bearing 63. A drive unit 68 for driving the threaded rod 64 to rotate is disposed on the top of the positioning frame 61. The outer surface of the threaded rod 64 is threadedly sleeved inside the adjusting groove 62. An adjusting plate 65 is used, and a crossbar 66 is fixedly connected between two adjusting plates 65. A pressure roller 67 is rotatably sleeved on the outer surface of the crossbar 66. During use, the base fabric is wound up by the winding mechanism 2, and the conveying direction of the base fabric is guided by the guide roller 8, so that the base fabric moves along the path of "pressure roller 67-tension roller 5-pressure roller 67". During the winding process, the tension sensor 4 and the tension roller 5 work together to detect the tension of the base fabric in real time during the winding process and send the tension data to the control panel 9. The control panel 9 controls the tension adjusting unit 6 to make corresponding adjustments based on the received tension data. The drive unit 68 drives the threaded rod 64 to rotate, so that the adjusting plate 65 moves up and down inside the adjusting groove 62, thereby adjusting the height of the pressure roller 67 located on the crossbar 66, and thus changing the winding tension of the base fabric. This effectively ensures the uniformity of the winding tension, prevents wrinkles in the fabric roll, and ultimately guarantees the quality of the product.

[0033] In this embodiment, as Figure 1 and 3 As shown, the tops of tension roller 5 and guide roller 8 are kept horizontally aligned, and the bottom of pressure roller 67 must be lower than the bottom of tension roller 5. During use, the tops of tension roller 5 and guide roller 8 are horizontally aligned to form a reference plane, ensuring that the fabric is horizontal when it enters the tension detection area, thus avoiding tension fluctuations caused by height differences. The design that the bottom of pressure roller 67 is lower than tension roller 5 allows the fabric path length to be changed by raising and lowering pressure roller 67, thereby directly adjusting the winding tension.

[0034] In this embodiment, as Figure 3-5As shown, the drive unit 68 includes a protective cover 681 fixedly mounted on the top of the positioning frame 61. Two transmission wheels 683 are arranged in parallel inside the protective cover 681. The two transmission wheels 683 are respectively sleeved on the outer surfaces of two threaded rods 64, and a transmission belt 684 is provided between the two transmission wheels 683. A drive motor 682 is fixedly mounted on the top of the protective cover 681. The output end of the drive motor 682 is fixedly connected to the upper end of one of the threaded rods 64. In use, the drive motor 682 drives the threaded rod 64 connected to it to transmit power, and the transmission wheels 683 and the transmission belt 684 drive the other threaded rod 64 to rotate synchronously.

[0035] In this embodiment, as Figure 3 As shown, the length of the adjusting plate 65 is the same as the length of the adjusting groove 62, and the width of the adjusting plate 65 is the same as the width of the adjusting groove 62. In use, the adjusting groove 62 limits the movement path of the adjusting plate 65, ensuring that the adjusting plate 65 can only move vertically along the axis of the threaded rod 64, avoiding deflection of the adjusting plate 65 during movement, thereby ensuring the accuracy of the movement of the adjusting plate 65.

[0036] In this embodiment, as Figure 1 and 2 As shown, the winding mechanism 2 includes a mounting frame 21 fixedly mounted on the upper surface of the workbench 1. A rotating shaft 22 is rotatably connected inside the mounting frame 21. A winding motor 23 that drives the rotating shaft 22 to rotate is fixedly mounted on the rear wall of the mounting frame 21. A fixing ring 24 is fixedly connected to the outer wall of the rotating shaft 22 near the mounting frame 21. A winding roller 25 and a moving ring 26 are slidably sleeved on the outer wall of the rotating shaft 22 outside the fixing ring 24. A locking ring 27 is threadedly sleeved on the outer wall of the rotating shaft 22 outside the moving ring 26. In use, the winding roller 25 is slidably sleeved on the rotating shaft 22, and together with the movable moving ring 26 and the locking ring 27, an adjustable clamping mechanism is formed to realize the installation of the winding roller 25. When disassembling, the winding roller 25 can be axially pulled out by simply loosening the locking ring 27. The winding motor 23 drives the rotating shaft 22 to rotate, thereby driving the winding roller 25 to rotate for winding.

[0037] In this embodiment, as Figure 2 As shown, both the fixed ring 24 and the movable ring 26 have protrusions 28 fixedly connected to the outer wall of the side near the take-up roller 25. The outer walls of both sides of the take-up roller 25 are symmetrically provided with grooves 29 that are adapted to the protrusions 28. The protrusions 28 are slidably inserted into the grooves 29. In use, by sliding the protrusions 28 into the grooves 29, the take-up roller 25 is locked on the rotating shaft 22 to ensure that the torque is transmitted to the take-up roller 25 without loss and to prevent the take-up roller from slipping.

[0038] In this embodiment, as Figure 1 and 5As shown, the tension sensor 4 is connected to the control panel 9 via a signal. The control panel 9 is electrically connected to the drive motor 682 via a wire. During use, the tension sensor 4 detects the tension of the base fabric during the winding process in real time and sends the tension data to the control panel 9. The control panel 9 dynamically adjusts the output of the drive motor 682 according to the tension deviation.

[0039] The working principle of this utility model is as follows: When using the winding machine for base fabric according to this application, the operator sequentially attaches the winding roller 25 and the moving ring 26 to the rotating shaft 22, and then tightens the locking ring 27 to fix the winding roller 25 on the rotating shaft 22. Then, the winding motor 23 is started to drive the winding roller 25 to rotate and wind the base fabric. The guide roller 8 guides the base fabric along the path of "pressure roller 67 - tension roller 5 - pressure roller 67". During the winding process, the tension sensor 4 and the tension roller 5 work together to detect the base fabric in real time during winding. The tension experienced during the winding process is measured and the tension data is sent to the control panel 9. The control panel 9 dynamically adjusts the output of the drive motor 682 according to the tension deviation. The drive motor 682 drives the threaded rod 64 connected to it for transmission. Through the transmission wheel 683 and the transmission belt 684, another threaded rod 64 is driven to rotate synchronously, so that the adjusting plate 65 moves up and down inside the adjusting groove 62 to adjust the height of the pressure roller 67, thereby changing the length of the base fabric's movement path and thus changing the winding tension experienced by the base fabric, ensuring the uniformity of the winding tension.
