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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 7 The present invention provides a technical solution: a tension adjustment device for yarn production, comprising a base plate 1, a mounting groove 2 is provided on the top surface of the base plate 1, four mounting grooves 2 are provided, and the four mounting grooves 2 are respectively distributed at the four corners of the top surface of the base plate 1, the mounting groove 2 is a "U"-shaped groove, and a bolt hole is provided on the bottom surface of the mounting groove 2. Two vertical plates 3 are fixed on the top surface of the base plate 1, and the surfaces of the two vertical plates 3 are slidably connected with a lifting frame 5. A support block 6 is fixed on the top surface of the lifting frame 5, and a tension adjustment roller 10 is rotatably connected between the two support blocks 6. A slide groove 4 is provided on the top surface of the vertical plate 3, and a sliding groove 4 is provided on the top surface of the vertical plate 3. The height of the groove 4 is less than the height of the vertical plate 3, and the support block 6 is slidably connected in the slide groove 4. A mounting opening 7 is provided on the surface of the support block 6, and a bearing 9 is fixed inside the mounting opening 7. The inner ring of the bearing 9 is sleeved on the end of the tensioning and adjusting roller 10; the lifting frame 5 is an annular plate structure, and hand screws 13 are screwed on both sides of the lifting frame 5. The hand screws 13 pass through the side plates of the lifting frame 5, and side grooves 11 are provided on both sides of the vertical plate 3. The height of the side grooves 11 is equal to the height of the vertical plate 3, and a rubber pad 12 is fixed inside the side grooves 11. The height of the rubber pad 12 is equal to the height of the side grooves 11.

[0025] The height of the tensioning roller 10 is adjusted as needed. The tensioning roller 10 is used to hold the yarn being transported upward, that is, the tensioning roller 10 is lifted to tension the yarn, and the tensioning roller 10 is dropped to relax the yarn. When adjusting the height of the tensioning roller 10, first loosen the hand screw 13, then pull the lifting frame 5 to slide along the vertical plate 3, and after the tensioning roller 10 reaches the specified position, tighten the hand screw 13 to clamp the rubber pad 12 to brake the lifting frame 5 and prevent the lifting frame 5 and the support block 6 from falling.

[0026] Two notches 14 are provided on the top surface of the vertical plate 3, and a limit shaft 15 is fixed between two parallel side walls of the notch 14, and a pulley 16 is sleeved on the shaft body of the limit shaft 15; the pulley 16 is added to the top of the vertical plate 3 so that when the equipment needs to be transferred after use, the equipment is inverted, and the pulley 16 contacts the ground at this time, which is convenient for pushing the equipment to slide.

[0027] Connecting plates 17 are fixed on both sides of the vertical plate 3, and a guide roller 20 is rotatably connected between the connecting plates 17 on the surfaces of the two vertical plates 3. A mounting opening 18 is provided on the surface of the connecting plate 17, and a bearing 19 is fixed inside the mounting opening 18. The inner ring of the bearing 19 is sleeved on the end of the guide roller 20; after the yarn passes around the bottom of one guide roller 20, the yarn is passed around the top of the tensioning adjustment roller 10, and then the yarn is passed around the bottom of the other yarn. The two guide rollers 20 conduct the yarn, and the tensioning adjustment roller 10 is used to tension the yarn.

[0028] The use process of the tension adjustment device for yarn production is as follows:

[0029] First, pass the yarn around the bottom of one of the guide rollers 20. The guide roller 20 rotates stably through the connecting plate 17 and the bearing 2 19, providing a smooth conduction path for the yarn. Then, pass the yarn around the top of the tensioning roller 10. At this time, the position of the tensioning roller 10 should be preset according to the initial tension requirement of the yarn. Finally, pass the yarn around the bottom of the other guide roller 20 to complete the preliminary installation of the yarn. Observe the tension of the yarn during the production process. If the tension needs to be adjusted, first loosen the hand screw 13 to release the clamping of the lifting frame 5. As needed, manually pull up and down the lifting frame 5 along the slide 4 of the vertical plate 3. The movement of the lifting frame 5 will drive the support block 6 and the tensioning roller 10 to move synchronously. When the tensioning roller 10 reaches the required height, re-tighten the hand screw 13 so that it clamps the rubber pad 12 in the side groove 11. The rubber pad 12 provides friction to prevent the lifting frame 5 and the tensioning roller 10 from falling accidentally. Repeatedly check the tension of the yarn to ensure that it meets the production requirements. When the equipment needs to be moved, first ensure that the equipment is powered off and in a safe state. Turn the equipment upside down so that the pulley 16 touches the ground. The pulley 16 is fixed in the notch 14 of the vertical plate 3 through the limit shaft 15, which facilitates the sliding of the equipment. Slowly push the equipment to the designated position, pay attention to keep it stable, and avoid damage caused by collision.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
