Tension control mechanism for DTY yarn processing

Abstract

This utility model relates to the field of tension control technology, and in particular to a tension control mechanism for DTY yarn processing. It mainly addresses the problem of loose DTY yarn at the initial position during raw material winding. This necessitates repeated adjustments of the tension rod at the initial position and observation of the DTY yarn's changes, leading to low installation efficiency. The proposed technical solution includes a control box with an externally fixed operating panel. A placement roller is rotatably connected to one side of the control box. This utility model uses a worm spring to drive a rotating tube and a rotating block, bringing the pushing roller as close as possible to the DTY yarn. The telescopic rod and pushing spring ensure sufficient pushing force from the pushing roller on the DTY yarn, ensuring the DTY yarn near the placement roller is stretched as much as possible. This minimizes the number of tension rod adjustments and improves the convenience of DTY yarn tension adjustment.

Description

Technical Field

[0001] This utility model relates to the field of tension control technology, and in particular to a tension control mechanism for DTY yarn processing. Background Technology

[0002] Tension control refers to the technology of automatically controlling the tension of strips, wires, profiles and their reprocessed products in various continuous production lines during processes such as rolling, drawing, embossing, coating, printing and dyeing, cleaning and winding. It is essential in the processing of DTY yarn.

[0003] When processing DTY yarn, the raw material needs to be placed outside the roller, one end of the raw material is pulled out from the placement position, and then the raw material is allowed to pass around the tension rod, so that the tension rod can spread and transmit the raw material, thereby achieving the effect of adjusting its tension.

[0004] However, during the winding of the raw material, the DTY yarn at the initial position becomes loose. This necessitates repeated adjustments to the tension rod at the initial position and observation of the DTY yarn's changes, resulting in low installation efficiency. Therefore, this invention proposes a tension control mechanism for DTY yarn processing. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background technology where the DTY filament at the initial position becomes loose when the raw material is wound. In this case, the tension rod at the initial position needs to be repeatedly adjusted and the changes in the DTY filament need to be observed, which leads to low installation efficiency. Therefore, a tension control mechanism for DTY filament processing is proposed.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example like Figures 1 to 4As shown, this utility model proposes a tension control mechanism for DTY yarn processing, including a control box 1. An operation panel 19 is fixedly connected to the outside of the control box 1. The operation panel 19 can control the control box 1 to manipulate parts on one side of the control box 1. A placement roller 2 is rotatably connected to one side of the control box 1, which can be used to store DTY yarn raw materials. A collection roller 3 is rotatably connected to one side of the control box 1 away from the placement roller 2, which can be used to collect DTY yarn with adjusted tension. An adjustment groove 18 is provided on the side of the control box 1 near the placement roller 2 and the collection roller 3. There are four adjustment grooves 18 arranged in a rectangular array. Tensioning rods 17 are slidably connected inside the adjustment grooves 18. There are two sets of tensioning rods 17 arranged symmetrically, allowing the DTY yarn to pass around the tensioning rods 17 and slide within the adjustment grooves 18, thereby adjusting the tension of the DTY yarn. The control box 1 has a rotating groove 4 near the roller 2. A rotating tube 6 is rotatably connected inside the rotating groove 4, and the rotating tube 6 can rotate inside the rotating groove 4. A rotating block 7 is fixedly connected to the side of the rotating tube 6 away from the rotating groove 4. A push frame 12 is set on one side of the rotating block 7. The push frame 12 is U-shaped and allows the DTY wire to pass over it. A support rod 13 is fixedly connected inside the push frame 12. A push roller 14 is slidably connected to the outside of the support rod 13. The DTY wire can be tightened by sliding outside the push roller 14. When the pulled-out DTY wire is in different positions, the push roller 14 slides outside the support rod 13 to adjust it. A positioning rod 8 is fixedly connected inside the rotating groove 4. An elastic component is set outside the positioning rod 8. The rotation of the rotating tube 6 inside the rotating groove 4 can be controlled by the elastic component outside the positioning rod 8.

[0023] For further details, please refer to Figures 4 to 6 The outer side of the push roller 14 has a concave structure, and the concave structure and its edge are rounded. The rounded concave structure of the push roller 14 ensures that the DTY thread will not detach. The elastic component includes a worm spring 5. The end of the worm spring 5 near the inside is fixedly connected to the outside of the positioning rod 8. The way the worm spring 5 is fixed to the outside of the positioning rod 8 restricts one end of it. The end of the worm spring 5 near the outside is fixedly connected to a connecting block 9. The connecting block 9 is fixedly connected to the inside of the rotating tube 6. When the rotating tube 6 rotates, the worm spring 5 will be stretched or rolled up outside the positioning rod 8 by the connecting block 9. When the rotating tube 6 is released, the elastic force of the worm spring 5 will drive the rotating tube 6 to return to its original position. The side of the rotating block 7 near the push frame 12 is fixedly connected to a push spring 11. The end of the push spring 11 away from the rotating block 7 is fixedly connected to the side of the push frame 12. The push spring 11 can push the push frame 12, allowing the push frame 12 to stretch the DTY thread to its initial position.

[0024] For further details, please refer to Figure 7A telescopic rod 10 is fixedly connected to the push frame 12 and the rotating block 7 on opposite sides. The telescopic rod 10 is located inside the push spring 11. The telescopic rod 10 can assist the push spring 11 in controlling the extension and retraction of the push frame 12, ensuring that the push frame 12 has sufficient opening force. A protective shell 16 is fixedly connected to the side of the rotating block 7 near the telescopic rod 10. A sliding shell 15 is slidably connected inside the protective shell 16. The end of the sliding shell 15 away from the protective shell 16 is fixedly connected to the side of the push frame 12 near the telescopic rod 10. The movement position of the push frame 12 can be limited by the sliding shell 15 inside the protective shell 16. The telescopic rod 10 and the push spring 11 are located inside the sliding shell 15 and the protective shell 16. The sliding shell 15 and the protective shell 16 can also protect the telescopic rod 10 and the push spring 11. The sliding shell 15 and the protective shell 16 are hollow rectangular structures. The rectangular structure of the protective shell 16 ensures better restriction of the sliding shell 15 inside it, and the contact area between the sliding shell 15 and the push frame 12 is larger.

[0025] In this embodiment, the DTY yarn raw material is placed outside the placement roller 2, and then one end of the DTY yarn is taken out and allowed to pass around the outside of the push roller 14. Then, the DTY yarn is passed around the tension rod 17 in sequence, and then this end is fixed to the outside of the collection roller 3. At this time, the control box 1 can be started through the operation panel 19, so that the placement roller 2 is released and the collection roller 3 is wound up. During the process of the placement roller 2 being released and the collection roller 3 being wound up, the tension rod 17 will slide inside the adjustment groove 18, thereby controlling the tension of the DTY yarn.

[0026] When the DTY wire initially passes around the push roller 14, the elastic force of the worm spring 5 will push the connecting block 9 at one end of the positioning rod 8 to drive the rotating tube 6 to rotate. This ensures that the rotating tube 6 will drive the rotating block 7 and the push frame 12 to push the DTY wire. The DTY wire placed outside the roller 2 will be supported at a position where it is very easy to loosen. This also ensures that the number of times the tension rod 17 needs to be adjusted is reduced.

[0027] When the push roller 14 contacts the DTY wire, the telescopic rod 10 and the push spring 11 will also push the push frame 12 to move towards the DTY wire position. In this way, the telescopic rod 10 and the push spring 11 can work with the worm spring 5 to open the DTY wire. The worm spring 5, the telescopic rod 10, and the push spring 11 can make the push roller 14 push the DTY wire closer to the position of the placement roller 2. When the telescopic rod 10 and the push spring 11 push the push frame 12, the sliding shell 15 slides inside the protective shell 16, which can protect the extension and retraction of the telescopic rod 10 and the push spring 11.

[0028] It should be noted that this device uses a worm spring 5 to drive the rotating tube 6 and the rotating block 7 to rotate, so that the pushing roller 14 is as close as possible to the DTY wire. The telescopic rod 10 and the pushing spring 11 ensure that the pushing roller 14 has sufficient pushing force on the DTY wire, ensuring that the DTY wire close to the placement roller 2 is stretched as much as possible, ensuring that the tension rod 17 does not need to be adjusted too many times, and improving the convenience of adjusting the tension of the DTY wire.

[0029] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
