Specific embodiments

[0026] In order to clearly and completely describe the objectives, technical solutions of the present invention and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0027] Please refer to Figure 1-Figure 8 , the present invention provides a technical solution: a tension adjusting device for yarn production, including a bracket 1. The bracket 1 has a "C"-shaped plate structure. Sliding seats 3 are slidably connected to both side plates of the bracket 1. A guide roller 10 is rotatably connected between the two sliding seats 3. An installation opening 8 is provided on the surface of the sliding seat 3, and a bearing 9 is fixed inside the installation opening 8. The inner ring of the bearing 9 is sleeved on the end of the guide roller 10. Chutes 2 are provided on both side plates of the bracket 1 distributed in parallel. The height of the chute 2 is less than the height of the side plate of the bracket 1. The sliding seat 3 is slidably connected in the chute 2, and the height of the sliding seat 3 is less than the height of the chute 2; a notch 6 is provided on the top surface of the chute 2, and an electric telescopic rod 7 is fixed on the bottom surface of the notch 6. The piston rod of the electric telescopic rod 7 is fixed on the bottom surface of the sliding seat 3. Limiting grooves 5 are provided on both side walls of the chute 2 distributed in parallel. Sliders 4 are slidably connected inside the limiting grooves 5, and the sliders 4 are fixed on the surface of the sliding seat 3.

[0028] During use, one end of the yarn is wound around the traction cylinder, the other end of the yarn is on the winding and storage cylinder, and the yarn bypasses below the guide roller 10. The guide roller 10 presses downward against the conveyed yarn. The yarn is pulled and moved by the traction device. When it is necessary to adjust the tension of the yarn during conveying, the switch of the electric telescopic rod 7 is triggered. When the piston rod of the electric telescopic rod 7 contracts, it pulls the sliding seat 3 to descend. At this time, the yarn is tightened. When the piston rod of the electric telescopic rod 7 extends, the sliding seat 3 is lifted and the yarn is relaxed.

[0029] The top surface of the side plate of the bracket 1 is plugged with a block 11, and the top surface of the block 11 is rotatably connected with a pulley 15. The block 11 is a "convex" plate-shaped structure, and a screw is screwed on the bottom plate of the block 11. The screw penetrates the bottom plate of the block 11 and is screwed on the top surface of the bracket 1. The bottom surface of the block 11 is fixed with an insert 12, and the insert 12 is inserted in the limit groove 5. The top surface of the block 11 is provided with two reserved grooves 13, and a limit shaft 14 is fixed between two parallel side walls of the reserved groove 13, and the pulley 15 is sleeved on the limit shaft 14. When the device is used, the device is inverted, and the pulley 15 contacts the ground at this time, which is convenient for pushing and transferring the device, and the block 11 is installed on the side plate of the bracket 1 to prevent the sliding seat 3 from falling off the side plate of the bracket 1.

[0030] Two pads 16 are fixed to the bottom surface of the bracket 1, and two receiving grooves 17 are provided on the bottom surface of the bracket 1. The two receiving grooves 17 are located between the two pads 16. A limiting axis 2 18 is fixed between two parallel side walls of the receiving groove 17. The limiting axis 2 18 passes through one end of a support plate 19. The support plate 19 is located inside the receiving groove 17. The support plate 19 is an "L"-shaped plate structure. A bolt hole is provided at one end of the support plate 19. A connecting screw 21 is screwed on the surface of the pad 16. A screw hole 22 is provided on the surface of the support plate 19. When the support plate 19 is vertical to the ground, one end of the pad 16 is screwed in the screw hole 22. A rubber clamp 20 is fixed at one end of the receiving groove 17. After the support plate 19 is retracted into the receiving groove 17, the rubber clamp 20 is clamped between the support plate 19 and the receiving groove 17 to generate elastic deformation.

[0031] When using the bracket 1, the support plate 19 is pulled out from the storage groove 17. When the support plate 19 is against one side of the cushion block 16, the connecting screw 21 is screwed and pushed to be screwed into the screw hole 22. At this time, the support plate 19 is limited, and the two support plates 19 support the bracket 1 together. The bottom plate of the support plate 19 can be fixed to the ground with bolts to improve the stability of the support of the support plate 19.

[0032] The use process of the yarn production tension adjustment device is as follows:

[0033] The stopper 11 is screwed to the top surface of the side plate of the bracket 1, and the insert 12 is inserted into the limit groove 5 to fix the sliding seat 3 and prevent it from falling off. The pulley 15 is installed on the top surface of the stopper 11 to ensure that the pulley 15 can rotate freely. The support plate 19 is pulled out from the storage groove 17 so that it leans against one side of the cushion block 16. The connecting screw 21 is screwed, pushed and screwed into the screw hole 22 of the support plate 19 to fix the support plate 19. If a more stable support is required, the bottom plate of the support plate 19 can be fixed to the ground with bolts. One end of the yarn is wound around the traction drum, and the other end is connected to the winding storage drum. The yarn is passed around the bottom of the guide roller 10 to ensure that the guide roller 10 can resist and convey the yarn. According to production requirements, the initial tension of the yarn is preset by the initial state of the electric telescopic rod 7 (piston rod extension or contraction). Start the traction equipment and start traction of the yarn for production. During the production process, if the tension of the yarn needs to be adjusted, the switch of the electric telescopic rod 7 is triggered. When the yarn needs to be tightened, the piston rod of the electric telescopic rod 7 is retracted; when the yarn needs to be loosened, the piston rod of the electric telescopic rod 7 is extended. Turn off the power of the traction device and the electric telescopic rod 7. Retract the support plate 19 into the receiving groove 17 and clamp it with the rubber clamp block 20. If the equipment needs to be moved, turn the equipment upside down so that the pulley 15 touches the ground. Push the equipment to the specified position through the pulley 15.
