Description

Technical Field

[0001] This application relates to the field of roll forming machines, and more particularly to a fabric pressing device for a roll forming machine. Background Technology

[0002] A fabric winding machine is a textile finishing device used to wind finished fabric into neat, tight cylindrical rolls.

[0003] The general working process of a roll-up machine is as follows: first, one end of the inspected fabric is passed through the guide roller, the roll-up roller starts to rotate, and the fabric is wound around the paper tube or plastic tube. The tension control system ensures that the winding is not too tight. When the preset length is reached, the fabric is cut and the completed roll is taken off.

[0004] In existing technologies, when rolling up fabric, a pressure bar is usually set on one side to apply a certain pressure to the fabric, expel air, and roll the fabric tightly. Existing pressure bars are usually pressed by springs, but the pressure of the pressure bar cannot be adjusted, resulting in poor pressing effect on fabrics with different winding degrees. Utility Model Content

[0005] To address the problem that the pressure of the pressure bar cannot be adjusted, resulting in poor pressing effect on fabrics with different winding degrees, this application provides a pressing device for a winding machine.

[0006] The fabric pressing device for a rolling machine provided in this application adopts the following technical solution: A fabric pressing device for a roll winding machine includes a frame disposed on one side of the roll winding machine body. A fabric pressing assembly is disposed on the frame. The fabric pressing assembly includes a fabric pressing rod and a push frame. The push frame is slidably mounted on the frame. The fabric pressing rod is disposed on the push frame and distributed parallel to the roll winding. A drive member is disposed on the frame for driving the push frame to slide. An elastic member is disposed on the push frame for driving the fabric pressing rod to move toward or away from the roll winding.

[0007] By adopting the above technical solution, the driving component drives the pusher frame to slide along the frame, thereby adjusting the position of the pressure bar relative to the fabric roll to adapt to the gradually increasing diameter change during the fabric roll winding process. The elastic component drives the pressure bar to move towards or away from the fabric roll, providing elastic clamping force to the pressure bar, reducing the probability of damage caused by clamping the fabric, and ensuring that the pressure bar can maintain a suitable clamping force under different winding degrees of the fabric, thus improving the pressing effect.

[0008] Optionally, the driving component includes a drive motor and a lead screw. The lead screw is rotatably mounted on the frame and is perpendicular to the pressing rod. The drive motor is mounted on the frame, and the lead screw is connected to the output shaft of the drive motor. The push frame is threadedly connected to the lead screw.

[0009] By adopting the above technical solution, the drive motor drives the lead screw to rotate, which in turn drives the push frame to slide along the lead screw axis. During the sliding process of the push frame, the pressing rod always remains parallel to the fabric roll, ensuring the stability and consistency of the pressing rod pressing the fabric.

[0010] Optionally, the frame is provided with a vertical groove, and a drive block is provided on one side of the push frame. The drive block is slidably connected to the frame through the vertical groove, and the drive block is threadedly connected to the lead screw.

[0011] By adopting the above technical solution, the vertical groove provides precise guidance for the sliding direction of the drive block, limiting the sliding of the push frame in the vertical direction and reducing lateral deviation or swaying of the push frame during the sliding process.

[0012] Optionally, the push frame is provided with a sliding groove, and a moving block is slidably installed on the push frame at the sliding groove. The pressing rod is rotatably connected to the moving block, and the elastic element is provided at the sliding groove of the push frame and connected to the moving block.

[0013] By adopting the above technical solution, the moving block slides in the sliding groove, and the elastic element pushes the moving block to drive the pressing rod to press it, ensuring that the pressing rod is in contact with the surface of the fabric roll. The pressing rod is rotatably connected to the moving block. When the fabric roll rotates and rewinds, the pressing rod passively rotates synchronously with the rotation of the fabric roll, converting the sliding friction between the pressing rod and the fabric into rolling friction, thereby reducing friction damage.

[0014] Optionally, the elastic element includes a spring, one end of which is connected to the movable block, and the push frame is provided with an adjusting element for adjusting the position of the spring.

[0015] By adopting the above technical solution, when the adjusting component pushes the spring to move towards the moving block, the spring compression increases, the elastic force on the moving block is enhanced, and thus the pressing force of the pressing rod on the fabric increases; when the adjusting component pulls the spring away from the moving block, the spring compression decreases, the pressing force decreases, and the pressing force can be flexibly adjusted according to the fabric material and winding requirements, thereby improving the versatility and pressing effect of the pressing device.

[0016] Optionally, the adjusting component includes an adjusting screw and an adjusting block. The adjusting screw is rotatably mounted in the sliding groove of the push frame, and the adjusting block is slidably connected to the push frame through the sliding groove. The end of the spring facing away from the moving block is connected to one side of the adjusting block.

[0017] By adopting the above technical solution, when the adjusting screw is rotated, the adjusting block moves along the sliding groove, thereby pushing or pulling the spring to change its pre-compression. The screw adjustment realizes micro-control, and the operator can accurately control the moving distance of the adjusting block through the screw, thereby precisely adjusting the compression and clamping force of the spring.

[0018] Optionally, a rotating handwheel is provided at the end of the adjusting screw opposite to the adjusting block.

[0019] By adopting the above technical solution, operators can drive the adjusting screw to rotate by turning the handwheel, which reduces the difficulty of operation and improves the convenience of adjusting the clamping force.

[0020] Optionally, a rubber layer is provided on the outer peripheral wall of the pressure rod.

[0021] By adopting the above technical solution, the rubber layer buffers the rigid pressure of the pressure rod on the fabric, reducing damage such as indentations and wear caused by the pressure rod directly contacting the fabric. In addition, the surface friction of the rubber layer is large, reducing the probability of relative sliding between the pressure rod and the fabric.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive unit drives the push frame to slide along the machine frame, which in turn adjusts the position of the pressure bar relative to the fabric roll to adapt to the diameter change during the fabric roll winding process. The elastic element provides elastic clamping force to the pressure bar to reduce fabric damage and keep the pressure bar with appropriate clamping force under different winding degrees, thereby improving the pressing effect. 2. The drive motor drives the lead screw to rotate, causing the push frame to slide along the lead screw axis. The pressing rod is always parallel to the fabric roll, ensuring the stability and consistency of the pressing. 3. The adjusting component can push or pull the spring to change its pre-compression amount, precisely adjusting the spring compression amount and the pressing force of the pressing rod, thus improving the versatility and pressing effect of the pressing device.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a fabric pressing device for a rolling machine, referring to... Figure 1 The machine includes a frame 2, a pressing assembly, a drive unit 5, and an elastic element. The frame 2 is located on one side of the winding machine body 1. The pressing assembly is mounted on the frame 2 and includes a pressing rod 3 and a pusher frame 4. The pressing rod 3 is mounted on the pusher frame 4 and is distributed parallel to the fabric roll. A rubber layer is provided on the outer peripheral wall of the pressing rod 3. The drive unit 5 is used to drive the pusher frame 4 in the pressing assembly to slide on the frame 2. The elastic element is mounted on the pusher frame 4 and is used to drive the pressing rod 3 to move towards or away from the fabric roll. The pressing rod 3 adapts to the diameter change during the fabric roll winding process, providing elastic clamping force to reduce the probability of damage caused by pressing the fabric. This ensures that the pressing rod 3 can maintain appropriate clamping force under different winding degrees of the fabric, improving the pressing effect.

[0029] Reference Figure 1 and Figure 2 The driving component 5 includes a drive motor 51 and a lead screw 52. A vertical slot 21 is provided on the frame 2. The lead screw 52 is vertically rotatably mounted in the vertical slot 21 of the frame 2. The drive motor 51 is mounted on the frame 2, and the lead screw 52 is connected to the output shaft of the drive motor 51. A drive block 41 is provided on one side of the push frame 4. The drive block 41 is slidably connected to the frame 2 through the vertical slot 21 and threadedly connected to the lead screw 52. When the drive motor 51 drives the lead screw 52 to rotate, the drive block 41 slides along the axial direction of the lead screw 52, ​​causing the pressure rod 3 to adjust its position relative to the fabric roll.

[0030] Reference Figure 1 and Figure 2 A horizontal sliding groove 42 is provided on the side of the push frame 4 away from the drive block 41. A moving block 43 is slidably installed on the push frame 4 at the sliding groove 42. The pressing rod 3 is rotatably connected to the moving block 43 through a bearing. When the fabric roll rotates and rewinds, the pressing rod 3 rotates passively and synchronously with the rotation of the fabric roll, converting the sliding friction between the pressing rod 3 and the fabric into rolling friction, thereby reducing friction damage.

[0031] Reference Figure 1 and Figure 2The elastic element includes a spring 6, one end of which is connected to a movable block 43. An adjusting element 7 for adjusting the position of the spring 6 is provided on the push frame 4. The adjusting element 7 includes an adjusting screw 71 and an adjusting block 72. The adjusting screw 71 is rotatably mounted in the sliding groove 42 of the push frame 4 and is distributed along the length of the sliding groove 42. The two ends of the adjusting screw 71 are located inside and outside the sliding groove 42, respectively. The adjusting block 72 is slidably connected to the push frame 4 through the sliding groove 42. The end of the spring 6 facing away from the movable block 43 is connected to one side of the adjusting block 72. When the adjusting screw 71 is rotated, the adjusting block 72 moves along the sliding groove 42, thereby pushing or pulling the spring 6 to change its pre-compression. A rotating handwheel 73 is provided at the end of the adjusting screw 71 facing away from the adjusting block 72. The operator drives the adjusting screw 71 to rotate by rotating the handwheel 73, reducing the difficulty of operation and improving the convenience of adjusting the clamping force.

[0032] The implementation principle of the fabric pressing device of the rolling machine in this embodiment is as follows: During rolling, the drive motor 51 drives the lead screw 52 to rotate, which in turn drives the push frame 4 to move vertically. The push frame 4 drives the pressing rod 3 to move, thereby adjusting the position of the pressing rod 3 relative to the fabric roll to adapt to the gradual increase in diameter during the rolling process. The elastic force of the spring 6 acts on the moving block 43, causing the pressing rod 3 to move towards the fabric roll direction, providing elastic pressing force to the pressing rod 3. When the rolling diameter of the fabric roll changes, the spring 6 will extend and retract accordingly to adjust the position and pressing force of the pressing rod 3.

[0033] The operator rotates the adjusting screw 71, which in turn moves the adjusting block 72 along the sliding groove 42, pushing or pulling the spring 6, thereby changing the pre-compression of the spring 6. As the winding radius gradually increases, the position of the adjusting block 72 is adjusted, which in turn adjusts the position of the pressure rod 3, while maintaining the clamping force of the spring 6.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
