[0002] In the textile industry, as a key device for fabric processing, the performance of the beam forming machine directly affects the quality and production efficiency of fabrics. During the fabric winding process, maintaining appropriate tension is crucial, because excessive tension may cause the fabric to break, while too little tension may cause the fabric to slack, affecting subsequent processing and use. Traditional tension adjustment methods often rely on manual adjustment, which is not only inefficient but also difficult to ensure the stability and uniformity of tension.

[0003] To solve the above problems, the industry has begun to explore automated and intelligent tension adjusting devices. A common solution is to achieve automatic adjustment of fabric tension through a mechanical structure. However, most of the existing tension adjusting devices have complex structures, high installation and maintenance costs, and in some cases, due to wear or failure of mechanical components, the tension adjustment may be inaccurate or ineffective.

[0004] Therefore, developing a tension adjusting device for a beam forming machine with a simple structure, easy installation, accurate adjustment, and low cost has become an urgent problem to be solved in the current textile industry. Content of the Utility Model

The piston rod of the electric telescopic rod penetrates through the top plate of the mounting frame, and the bottom end of the piston rod of the electric telescopic rod is fixed with a lifting frame. A tension roller is rotatably connected inside the lifting frame. Connecting blocks are fixed at both ends of the lifting frame. One end of each connecting block is fixed with a traction plate. The traction plate penetrates through the top plate of the mounting frame, and the top end of the traction plate is rotatably connected with a pulley.

[0007] Preferably, the mounting frame is in a "π"-shaped plate structure. Rubber pads are fixed at both ends of the mounting frame. The rubber pads are in an "L"-shaped plate structure. Bolt holes are provided on the top plates of the mounting frame and the rubber pads.

[0023] In order to clearly and completely describe the purpose and technical solutions of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments. They are only used to explain the embodiments of the present utility model and are not used to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figures 1 to 9 , the present utility model provides a technical solution: a tension adjusting device for a beam winder, including a mounting frame 1 for mounting on the frame of the beam winder. The mounting frame 1 is in a "π"-shaped plate structure, and rubber pads 2 are fixed at both ends of the mounting frame 1. The rubber pads 2 are in an "L"-shaped plate structure, and bolt holes 3 are provided on the top plates of the mounting frame 1 and the rubber pads 2; the mounting frame 1 is lapped on the frame of the beam winder. When the fabric is being wound by the winding roller, the fabric passes under the mounting frame 1. In order to reinforce the installation of the mounting frame 1, bolts are passed through the bolt holes 3 and the holes on the surface of the beam winder, and then the bolts are tightened, thus completing the fixation of the mounting frame 1 on the beam winder.

[0025] An electric telescopic rod 4 is fixed on the top surface of the mounting frame 1. The piston rod of the electric telescopic rod 4 penetrates through the top plate of the mounting frame 1, and a lifting frame 5 is fixed at the bottom end of the piston rod of the electric telescopic rod 4. A tension roller 7 is rotatably connected inside the lifting frame 5. The lifting frame 5 is in a "匚"-shaped plate structure. The lifting frame 5 is located between the two parallel side plates of the mounting frame 1. A limiting shaft 1 6 is fixed between the two parallel side plates of the lifting frame 5. The tension roller 7 is sleeved on the rod body of the limiting shaft 1 6; during the winding process of the fabric, the fabric is pressed down by the tension roller 7, and the tension roller 7 plays the role of a guiding roller. When it is necessary to tension the fabric, the switch of the electric telescopic rod 4 is triggered. After the piston rod of the electric telescopic rod 4 extends a short distance, the lifting frame 5 is pushed down by the electric telescopic rod 4, and the tension roller 7 squeezes the fabric downward to achieve the tensioning of the fabric during transportation.

[0026] Both ends of the lifting frame 5 are fixed with connecting blocks 8, and one end of the connecting block 8 is fixed with a traction plate 9. The traction plate 9 passes through the top plate of the mounting frame 1. There are two connecting blocks 8, which are symmetrically distributed about the lifting frame 5. The traction plate 9 has a "T"-shaped plate structure and passes through a through-hole 10. The through-hole 10 is opened on the surface of the mounting frame 1, and the top of the traction plate 9 is rotatably connected to a pulley 13. The top surface of the traction plate 9 has two notches 11. A limit shaft 2 12 is fixed between the two parallel side walls of the notches 11. The pulley 13 is sleeved on the shaft of the limit shaft 2 12. When the lifting frame 5 is pulled to lift, the lifting frame 5 pulls the traction plate 9 to move synchronously through the connecting blocks 8 to prevent the lifting frame 5 from swinging in the mounting frame 1. When the mounting frame 1 is removed from the shaft-connecting machine, the mounting frame 1 is inverted and the pulley 13 contacts the ground, which facilitates the sliding transfer of the mounting frame 1.

[0027] The detailed procedure for using the tension adjustment device of the parallel shaft machine is as follows:

[0028] Place mounting bracket 1 (a "π"-shaped plate structure) on the frame of the coaxial machine, ensuring that both ends of mounting bracket 1 are aligned with the frame. Check that the rubber pads 2 ("L"-shaped plate structures) at both ends of mounting bracket 1 are intact, ensuring they can increase friction and protect the frame surface. Through the bolt holes 3 on the top plates of mounting bracket 1 and rubber pads 2, pass bolts through these holes and the corresponding holes on the surface of the coaxial machine, then use a screwdriver or wrench to tighten the bolts, ensuring that mounting bracket 1 is securely fixed to the frame.

[0029] Place the lifting frame 5 (in the shape of a "U" - shaped plate structure) between the two parallel - distributed side plates of the mounting frame 1, and ensure that it can firmly support the tensioning roller 7. Fix the first limiting shaft 6 between the two parallel - distributed side plates of the lifting frame 5, and then sleeve the tensioning roller 7 on the rod body of the first limiting shaft 6. According to needs, by triggering the switch of the electric telescopic rod 4, adjust the height of the lifting frame 5, thereby changing the downward pressure of the tensioning roller 7 on the fabric, and realizing the adjustment of the fabric tension. Fix the connecting block 8 at both ends of the lifting frame 5, and then connect the traction plate 9 (in the shape of a "T" - shaped plate structure) to the lifting frame 5 through the connecting block 8. Ensure that the traction plate 9 can smoothly penetrate through the through - hole 10 on the surface of the mounting frame 1. Rotate and connect a pulley 13 at the top of the traction plate 9, and sleeve the pulley 13 on the shaft body of the second limiting shaft 12. During the process of winding the fabric, the tensioning roller 7 plays the role of a guiding roller. According to the tension requirements of the fabric, timely trigger the switch of the electric telescopic rod 4 to adjust the height of the lifting frame 5 and the downward pressure of the tensioning roller 7. Observation and adjustment: Continuously observe the tension condition of the fabric and make fine - tuning according to needs. When it is necessary to remove the tension - adjusting device, first cut off the power supply of the electric telescopic rod 4. Use a screwdriver or wrench to remove the bolts fixing the mounting frame 1. Take the mounting frame 1 off the machine frame and invert it so that the pulley 13 touches the ground. Through the sliding function of the pulley 13, conveniently push the mounting frame 1 for transfer or storage.
