Description

Technical Field

[0001] The utility model relates to a tension constant device, in particular to a tension constant device of a wire dividing machine, and belongs to the technical field of textile machinery. Background Art

[0002] Among chemical fiber filaments, except for spandex filaments, polyester and nylon twisted edge yarns and nylon fishing lines, which are generally monofilaments, other filaments are almost all multifilaments. Therefore, they often need to be separated before they can be used in the next process. The existing separation machine is generally complex in structure and has the following technical defects:

[0003] The existing wire splitting machine cannot ensure that the wire is conveyed and decomposed at the same speed, and the tension varies greatly. If the tension between each single wire is inconsistent, it will lead to differences in weaving and dyeing, greatly reducing the product quality.

[0004] Therefore, it is a prerequisite for successful weaving to maintain constant tension throughout the entire warp length and to keep all the yarns in the warp layer consistent in tension. However, the constant tension runs through the entire wire separation process, including unwinding, wire separation and winding. Therefore, the development of a constant tension device for the wire separation machine can bring the constant tension to a new level.

[0005] Based on this, the present utility model is proposed. Utility Model Content

[0006] In view of the above technical problems of the prior art, the purpose of the utility model is to provide a constant tension device for a wire splitting machine, which is used between the unwinding device and the wire splitting roller to ensure constant tension of the mother wire before wire splitting, laying a foundation for constant tension after wire splitting.

The multifilament thread passes through wire passer 1, wire passer 3 and wire passer 2 in sequence from an unwinding device and then enters a wire dividing roller.

[0009] The front baffle is provided with a transverse groove 1 and a transverse groove 2 on both sides respectively. A sliding rod 1 is provided in the transverse groove 1, and the wire passer 1 is installed at the end of the sliding rod 1. A sliding rod 2 is provided in the transverse groove 2, and the wire passer 2 is installed at the end of the sliding rod 2.

[0010] The constant tension device is installed on a wire dividing machine when in use. The wire dividing machine comprises a frame on which an unwinding device, a wire dividing device and a winding device are installed.

[0011] The wire dividing device includes a wire dividing roller, a wire dividing plate 1 and a wire dividing plate 2 from top to bottom, and an overfeed roller assembly is arranged between the wire dividing plate 1 and the wire dividing plate 2. After the multifilament yarn passes through the tension constant device from the unwinding device, it enters the wire dividing roller, the wire dividing plate 1, the overfeed roller assembly and the wire dividing plate 2 in sequence, and is finally wound and formed by the winding device.

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto.

[0021] like Figure 1-5 As shown, during the wire splitting process, the distance from the mother wire frame 1 to the wire splitting roller 4 is relatively long. To further maintain the constant wire tension, the constant tension device 3 of the wire splitting machine of the utility model is installed between the unwinding device and the wire splitting device. The constant tension device 3 includes a mounting seat 31, which is directly mounted on the frame 20, and the mounting seat 31 is provided with a front baffle 32, and the two sides of the front baffle 32 are respectively provided with a wire passer 1 33 and a wire passer 2 34, and a wire passer 3 35 is provided in the middle of the front baffle 32. The multifilament wire passes through the wire passer 1 33, the wire passer 3 35 and the wire passer 2 34 from the unwinding device in sequence and then enters the wire splitting roller 4.

[0022] In actual use, the tension of the wire will be selected according to the requirements of the subsequent process. The utility model is provided with a transverse groove 1 36 and a transverse groove 2 38 on both sides of the front baffle 32, and a sliding rod 1 37 is provided in the transverse groove 1 36. The sliding rod 1 37 passes through the transverse groove 1 36. After selecting a suitable position in the transverse groove 1 36 according to actual needs, the wire passer 1 33 is installed at the end of the sliding rod 1 37, and both ends of the sliding rod 1 37 are tightened by nuts 310. Similarly, a sliding rod 2 39 is provided in the transverse groove 2 38. The sliding rod 2 39 passes through the transverse groove 2 38. After selecting a suitable position in the transverse groove 2 38 according to actual needs, the wire passer 2 34 is installed at the end of the sliding rod 2 39, and both ends of the sliding rod 2 39 are tightened by nuts 310. In this way, different positions can be selected according to the requirements of the wire tension.

[0023] The wire dividing machine also includes a frame 20, on which an unwinding device, a wire dividing device and a winding device are installed. The unwinding device includes a mother wire rack 1 and a wire withdrawing wheel 2. The mother wire rack 1 is controlled by a damping motor with a brake. The specific structure of this type of motor is a conventional structure in the motor field. When applied to the utility model, the motor speed can be adjusted according to the thickness of the mother wire in the mother wire rack 1. During the mother wire dividing process, the mother wire on the mother wire rack 1 becomes less and less, and the mother wire rack 1 becomes lighter and lighter. At this time, the speed of rotation of the mother wire rack 1 is made consistent with the previous one by adjusting the speed of the damping motor, thereby further controlling the tension of the mother wire.

[0024] Further, the wire separation device in the utility model includes a wire separation roller 4, a wire separation plate 1 5 and a wire separation plate 2 6 from top to bottom. In order to meet the constant tension of the wire after the wire separation, the utility model is provided with an overfeed roller assembly 7 between the wire separation plate 1 5 and the wire separation plate 2 6. The overfeed roller assembly 7 includes a left roller 71 and a right roller 72. An upper wire separation roller 73 and a lower wire separation roller 74 are provided between the left roller 71 and the right roller 72. The wire enters the upper wire separation roller 73, the left roller 71, the right roller 72 and the lower wire separation roller 74 from the wire separation plate 1 5 in turn, and then enters the wire separation plate 2 6. In this way, the constant tension of the wire between the wire separation plate 1 5 and the wire separation plate 2 6 is achieved.

[0025] In order to achieve constant tension during the winding process, the winding device in the utility model changes the vertically placed winding tube into a horizontally placed reel, and adds a second constant tensioner, so that the silk thread is evenly wound in the reel through the yarn guide 19, ensuring constant tension of the silk thread during the winding process. The specific structure of the winding device is as follows:

[0026] The machine comprises a winding drive motor 8 and a turning frame 9 mounted on a frame 20. A driving roller 10 is provided at the output end of the winding drive motor 8. A plurality of rubber rollers 11 are arranged in parallel on the driving roller 10. A reel is installed on the turning frame 9. A compression spring 12 and a tension spring 13 are arranged on the turning frame 9. The reel is pressed down to the top of the rubber roller 11 by the compression spring 12 and the tension spring 13, and the reel is driven to rotate by the rotation of the rubber roller 11. When in use, three rows of winding devices are arranged in parallel horizontally below the frame 20. Each row of winding devices can work independently. The other specific structures of the winding devices are the same as those of the winding devices in the texturizing machine, such as those described in patents CN2741997Y, CN201125107Y and CN202265255U, which will not be described in detail here.

[0027] In order to make the winding balanced and ensure the tension of the silk thread during winding, the utility model sets a constant tensioner 2 on one side of the rubber roller 11, and the constant tensioner 2 includes a pulley 14, a pulley 2 15 and a driving wheel 16, and a belt 17 is provided on the pulley 14, the pulley 2 15 and the driving wheel 16, and the installation position of the pulley 14, the pulley 2 15 and the driving wheel 16 makes the belt 17 triangular, and a guide rail 18 is provided between the pulley 14 and the pulley 2 15, and a yarn guide 19 is provided on the guide rail 18. A driving motor is connected below the driving wheel 16, and the driving motor is controlled by a control panel. The speed of the driving motor can be adjusted according to the actual situation of winding, thereby adjusting the speed of the driving wheel 16, further adjusting the speed of the belt 17, and finally adjusting the speed of the yarn guide 19, thereby affecting the position of the silk thread winding in the reel, and ensuring constant tension during winding. The specific adjustment method of the control panel for the driving motor is common knowledge in the art, and will not be repeated here.

[0028] In summary, the tension constant device of the wire dividing machine of the utility model, when in use, the multifilament thread passes through the tension transverse device 3 from the unwinding device and then enters the wire dividing roller 4, the wire dividing plate 1 5, the overfeed roller assembly 7 and the wire dividing plate 2 6 in sequence, and finally is wound up by the winding device. A tension constant device is provided in each process to ensure that the tension of the thread is constant throughout the whole process from unwinding to winding, laying a foundation for improving the quality of weaving and dyeing.

[0029] The above embodiments are only used to explain the inventive concept of the utility model, rather than to limit the protection of the rights of the utility model. Any non-substantial changes to the utility model using this concept should fall within the protection scope of the utility model.
