[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 the separated silk threads are easy to slip during transportation, and the tension varies greatly. If the tension between each monofilament is inconsistent, it will lead to differences in weaving and dyeing, which greatly reduces the product quality.

DETAILED DESCRIPTION

[0016] 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.

[0017] like Figure 1-5 As shown, the overfeed roller assembly 7 of the wire-separating machine of the utility model comprises a left roller 71 and a right roller 72, an upper wire-separating roller 73 and a lower wire-separating roller 74 are arranged between the left roller 71 and the right roller 72, and the monofilament yarn enters the upper wire-separating roller 73, the left roller 71, the right roller 72 and the lower wire-separating roller 74 successively.

[0018] The utility model is installed on a wire-splitting machine when in use. The wire-splitting machine includes a frame 20, on which are installed an unwinding device, a wire-splitting device and a winding device. The wire-splitting device includes a wire-splitting roller 4, a wire-splitting plate 1 5 and a wire-splitting plate 2 6 from top to bottom. To meet the requirement of constant wire tension after wire-splitting, an overfeed roller assembly 7 is installed between the wire-splitting plate 1 5 and the wire-splitting plate 2 6. After the multifilament wire is separated by the wire-splitting roller 4, the monofilament wire enters the upper wire-splitting roller 73, the left roller 71, the right roller 72 and the lower wire-splitting roller 74 from the wire-splitting plate 1 5 in turn, and then enters the wire-splitting plate 2 6, and finally is wound and formed by the winding device. In this way, the constant tension of the wire between the wire-splitting plate 1 5 and the wire-splitting plate 2 6 is achieved, and the wire can be effectively prevented from slipping, laying a foundation for improving the quality of weaving and dyeing.

[0019] It is further provided that the unwinding device in the utility model comprises a mother wire rack 1 and a wire unwinding 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 in 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 separation 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.

[0020] In the process of silk separation, the distance from the mother wire frame 1 to the silk separation roller 4 is relatively long. In order to further maintain the constant silk tension, the utility model is provided with a constant tension device 3 between the unwinding device and the silk separation 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 silk thread 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 silk separation roller 4.

[0021] 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 side plate 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.

[0022] 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:

[0023] 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.

[0024] 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.

[0025] In summary, the utility model has a constant tension wire splitting machine. When in use, the multifilament wire passes through the constant tension device 13 from the unwinding device and then enters the wire splitting roller 4 in sequence. After being split by the wire splitting roller 4, the wire enters the wire splitting plate 15, the upper wire splitting roller 73, the left roller 71, the right roller 72 and the lower wire splitting roller 74 in sequence, and then enters the wire splitting plate 26, and finally is wound up by the winding device. A constant tension device is provided in each process to ensure that the tension of the wire is constant throughout the process from unwinding to winding, which lays a foundation for improving the quality of weaving and dyeing.

[0026] 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.
