Abstract
Description
Technical Field
[0001] The present application relates to the technical field of textile machinery and equipment, and in particular to a flat yarn tension adjustment mechanism. Background Art
[0002] Flat wire usually refers to a flat filamentary material, which is commonly used in plastic woven bags, geotextiles, packaging materials, ropes, fishing nets and other industries. The production process of flat wire mainly includes melting, extrusion, cooling, stretching, flattening and winding. Flat wire has a wide range of applications in industrial and civil fields due to its high strength, wear resistance and corrosion resistance.
[0003] During the winding process of the tape, it is a challenge to maintain a constant tension. Too little tension may cause the tape to relax, affecting the winding quality; too much tension may cause the tape to overstretch or even break, affecting the physical properties of the tape.
[0004] In the prior art, before the flat wire is wound up, several tensioning wheels are usually arranged between the flat wire unwinding and winding devices as tension control devices to tension the flat wire during the conveying process and to synchronize the rotation speeds of the flat wire unwinding roller and the winding roller as much as possible during the flat wire conveying process.
[0005] However, when conveying flat wires of different materials and specifications, the tension control device may need to be frequently adjusted to adapt to different tension requirements, and the tension control device cannot be fully automated and requires manual assistance, thereby increasing the complexity and cost of the operation. Utility Model Content
[0006] In order to improve the degree of automation of tension adjustment during the conveying process of flat yarns, the present application provides a flat yarn tension adjustment mechanism.
[0007] The flat wire tension adjustment mechanism provided in this application adopts the following technical solution:
[0008] A flat wire tension adjustment mechanism comprises a support frame, on which a rubber roller is rotatably arranged, and a driving motor for driving the rubber roller to rotate is arranged on one side of the support frame, and two pressure rollers arranged parallel to the rubber roller are also arranged on the support frame, the two pressure rollers are located on the same side of the rubber roller, and equidistant gaps are left between the two pressure rollers for the flat wire to pass through, the flat wire is wound in between the two pressure rollers, passes through one of the equidistant gaps through the winding rubber roller for one circle, and then comes out from the other equidistant gap, and then winds away from the pressure roller between the two pressure rollers, and the rotation speed of the driving motor is regulated according to the tension requirement.
[0009] By adopting the above technical solution, the flat wire is firstly wound between the two pressure rollers, and passes through the winding rubber roller from one of the equidistant gaps for one circle, then passes through the other equidistant gap, and then winds off the pressure roller from between the two pressure rollers. During the flat wire conveying process, the driving motor drives the rubber roller to rotate, and when the flat wire passes between the two pressure rollers and the rubber roller, the tension of the flat wire is controlled by the rubber roller through the friction between the flat wire and the rubber roller, and the rotation speed is automatically adjusted by the driving motor, so that the wrap angle and friction of the flat wire on the rubber roller can be changed, thereby realizing automatic adjustment of the tension of the flat wire, and improving the degree of automation of tension adjustment during the flat wire conveying process.
[0010] Optionally, the support frame is rotatably provided with a guide roller on one side of the flat wire that winds out of the rubber roller, and the guide roller is arranged parallel to the pressure roller.
[0011] By adopting the above technical solution, the setting of the guide roller can better guide the output direction of the flat wire, avoid the flat wire from being offset or twisted during the output process, and further improve the stability of tension control.
[0012] Optionally, a reducer is further arranged between the driving motor and the rubber roller, and a synchronization component is arranged between the output shaft of the driving motor and the input shaft of the reducer. The synchronization component includes a driving pulley mounted on the output shaft of the driving motor, a driven pulley mounted on the input shaft of the reducer, and a synchronous belt mounted on the driving pulley and the driven pulley together.

[0015] By adopting the above technical solution, the setting of the support ring facilitates the improvement of the stability of the rubber roller's rotation when installing the rubber roller, and the clamping arc plate slides in the direction toward the rubber roller axis under the action of the driving member, thereby achieving the coaxial alignment of the rubber roller's rotating shaft and the output shaft of the reducer. This structure can ensure the stability of the rubber roller's rotation and further improve the accuracy of tension control.
[0016] Optionally, a driving rod is slidably arranged between each of the clamping arc plates and the support ring, and the length direction of each of the driving rods is perpendicular to the axial direction of the rubber roller. One end of a single driving rod is fixed on the side wall of the corresponding clamping arc plate away from the rubber roller, and the other end slides through the support ring and extends out of the outer ring side wall of the support ring.
[0017] By adopting the above technical solution, the driving rod is driven to slide along its own length direction, and the driving rod pushes the clamping arc plate to approach the outer ring side wall of the rubber roller shaft until the clamping arc plate and the outer ring side wall of the rubber roller shaft are in contact with each other, thereby achieving the effect of adjusting the coaxiality of the rubber roller shaft and the output shaft of the reducer.
[0018] Optionally, the driving rod is a screw, and the driving member includes a gear ring that is coaxial with the support ring and rotatably arranged on the inner ring side wall of the support ring, a driven gear threadedly sleeved on the screw, a driving gear meshing with the gear ring, and a brake motor that drives the driving gear to rotate, the driving gear and the driven gear are both meshed with the gear ring, and a guide member for realizing screw sliding is arranged between the screw and the support ring.
[0019] By adopting the above technical solution, when the coaxiality between the rubber roller shaft and the output shaft of the reducer needs to be adjusted, the brake motor is started to drive the driving gear to rotate, thereby driving the driven gear and the screw to rotate. Since the screw is fixedly connected to the clamping arc plate, the rotation of the screw will drive the clamping arc plate to slide in the direction toward the axis of the rubber roller, thereby achieving the coaxiality adjustment, wherein the setting of the guide can ensure the stability and accuracy of the screw during the sliding process.
[0020] Optionally, a limiting groove is provided on the shaft of the screw along its length direction, and the guide member is a limiting block arranged on the inner wall of the through hole in the support ring for the screw to pass through, and the limiting block is located in the limiting groove and slidably cooperates with the limiting groove.
[0021] By adopting the above technical solution, the sliding fit between the limit block and the limit groove can ensure that the screw rod will not rotate or deviate during the sliding process, thereby further improving the adjustment accuracy and stability.
[0022] Optionally, a universal joint is connected between the output shaft of the reducer and the rotating shaft of the rubber roller passing through the support seat.
[0023] By adopting the above technical solution, the setting of the universal joint can better adapt to the angle change between the output shaft of the reducer and the rotating shaft of the rubber roller, reduce the wear and vibration caused by the angle deviation, and thus improve the service life and stability of the mechanism.

During the flat wire conveying process, the driving motor drives the rubber roller to rotate. When the flat wire passes between the two rollers and the rubber roller, the friction between the flat wire and the rubber roller is used to control the tension of the flat wire by the rubber roller. The rotation speed is automatically adjusted by the driving motor, which can change the wrap angle and friction of the flat wire on the rubber roller, thereby realizing automatic adjustment of the tension of the flat wire and improving the degree of automation of tension adjustment during the flat wire conveying process.

Then the flat wire 01 is wound between the two pressure rollers 3, passes through an equidistant gap on the rubber roller 2, and after winding around the rubber roller 2 for one week, it passes through another equidistant gap and is wound away from the two pressure rollers 3. The speed of the drive motor 5 is adjusted according to the tension demand to achieve automatic adjustment of the tension of the flat wire 01.
[0037] Reference Figure 1 The synchronous assembly 7 includes a driving pulley 71, a driven pulley 72 and a synchronous belt 73. The driving pulley 71 is fixedly sleeved on the output shaft of the driving motor 5, the driven pulley 72 is fixedly sleeved on the input shaft of the reducer 6, and the synchronous belt 73 is sleeved on the driving pulley 71 and the driven pulley 72.
[0038] Reference Figure 3 The clamping assembly 8 includes a plurality of clamping arc plates 81 and a driving member 82. The plurality of clamping arc plates 81 are distributed along the circumference of the inner ring of the support ring 11. A driving rod 811 is slidably arranged between each clamping arc plate 81 and the support ring 11. The driving rod 811 in this embodiment is a screw, and the length direction of each screw is perpendicular to the axial direction of the rubber roller 2. One end of a single driving rod 811 is fixedly arranged on the side wall of the corresponding clamping arc plate 81 away from the rubber roller 2, and the other end slides through the support ring 11 and extends out of the outer ring side wall of the support ring 11.
[0039] Reference Figure 3 A guide member 9 is provided between the screw and the support ring 11, and a limiting groove 8111 is provided on the rod body of the screw along its own length direction. The guide member 9 in this embodiment is a limiting block fixedly arranged on the inner wall of the through hole in the support ring 11 for the screw to pass through, and the limiting block and the limiting groove 8111 are slidably matched.
[0040] Reference Figure 3 The driving member 82 includes a ring gear 821, a driven gear 822, a driving gear 823 and a brake motor 824. The ring gear 821 is coaxially arranged with the support ring 11 and is rotatably arranged on the inner ring side wall of the support ring 11.

[0041] The implementation principle of a flat wire tension adjustment mechanism in the embodiment of the present application is as follows: the adjustment mechanism is installed before conveying the flat wire 01, and firstly, the reducer 6 and the drive motor 5 are connected and installed through the synchronous belt 73:
[0042] Insert both ends of the rubber roller 2 into the support ring 11, and drive the brake motor 824 to work. The output shaft of the brake motor 824 rotates to drive the driving gear 823 to rotate. The driving gear 823 rotates to drive the gear ring 821 meshing with it to rotate. The gear ring 821 rotates to drive several driven gears 822 meshing with it to rotate synchronously, and each driven gear 822 rotates to drive the corresponding screw to rotate. One brake motor 824 can drive several screws to rotate synchronously. When the screw rotates, due to the restriction of the limit block on the screw limit groove 8111, the screw can only slide in the direction toward the axis of the rubber roller 2, thereby driving the clamping arc plate 81 to slide synchronously in the direction toward the axis of the rubber roller 2, until the clamping arc plate 81 fits with the outer ring of the rubber roller 2, so that the rotating shaft of the rubber roller 2 is coaxially aligned with the output shaft of the reducer 6, and finally the universal joint is connected to the opposite ends of the rubber roller 2 and the output shaft of the reducer 6 to complete the installation.
[0043] During the conveying process of the flat wire 01, the flat wire 01 is wound in between the two pressure rollers 3, passes through an equidistant gap on the rubber roller 2, and after winding around the rubber roller 2 for one circle, it passes through another equidistant gap and is wound away from between the two pressure rollers 3. The speed of the driving motor 5 is regulated according to the tension requirement to realize automatic adjustment of the tension of the flat wire 01.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
