Description

Technical Field

[0001] This utility model relates to the field of composite fiber processing technology, specifically a composite fiber tensioning device. Background Technology

[0002] Composite synthetic fibers are fibers with textile properties produced by using two or more polymer compounds as raw materials, through processes such as preparing spinning solutions, spinning, and post-treatment. In the current field of synthetic fiber processing, the synthetic fibers are tensioned before winding to maintain a certain tension during the winding process. If the fiber bundle cannot be tensioned during synthetic fiber production and remains in a loose state, it will affect the continuous transport of the fiber bundle and may lead to substandard quality of the finished synthetic fiber product.

[0003] Different synthetic fibers have different tension requirements, and most existing tensioning devices meet these requirements by replacing springs of different models. However, the replacement of springs is inconvenient and therefore cannot meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a composite chemical fiber tensioning device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The composite chemical fiber tensioning device includes a base, on which a vertical plate is mounted. An inlet wheel and an outlet wheel are mounted at both ends of one side of the vertical plate. The device also includes a rotating plate rotatably connected to the vertical plate, located between the inlet and outlet wheels. Movable thread wheels are mounted at both ends of the rotating plate. A double-threaded screw is mounted on the other side of the vertical plate, with a rotating wheel at its upper end. The double-threaded screw has two sections of external threads with opposite directions of rotation. The two sections of external threads of the double-threaded screw are respectively threaded... The device includes a slider with a side rod on one side, a through groove for the side rod to move on the upright plate, extension plates at both ends of the rotating plate, a crossbar on one side of the extension plate, a slot on the crossbar, a stop bar with one end located inside the slot and rotatably connected to the crossbar, and a spring element with through holes at both ends. The spring element is installed on the side rod and the crossbar through the through holes at both ends. When the spring element is fitted onto the crossbar, the central axis of the stop bar coincides with the central axis of the crossbar.

[0006] Preferably, the outer surface of the stop bar is provided with two protrusions.

[0007] Preferably, a protective shell is provided on one side of the upright plate, the double-threaded screw and the slider are located between the protective shell and the upright plate, and the slider can move along the protective shell.

[0008] Preferably, the upright plate is provided with an anti-torsion plate, and the wire feed wheel is located below the anti-torsion plate.

[0009] Preferably, the base is provided with a waist hole, and a reinforcing plate is provided between the base and the upright plate.

[0010] The beneficial effects of this utility model are:

[0011] When in use, this device can adjust the tension of the two elastic components by controlling the distance between the two sliders. When the tension of the elastic components is higher, the tension of the chemical fiber is higher, and when the tension of the elastic components is lower, the tension of the chemical fiber is lower. It is easy to adjust and can limit the position of the stop bar by the elastic components to prevent the thread in the movable thread wheel from jumping off. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-4As shown, a composite chemical fiber tensioning device includes a base 1, on which a vertical plate 3 is mounted. An inlet wheel 4 and an outlet wheel 5 are mounted at both ends of one side of the vertical plate 3. The device also includes a rotating plate 6 rotatably connected to the vertical plate 3, located between the inlet wheel 4 and the outlet wheel 5. Movable thread wheels 7 are mounted at both ends of the rotating plate 6. A double-threaded screw 8 is mounted on the other side of the vertical plate 3. A rotating wheel 9 is mounted at the upper end of the double-threaded screw 8. The double-threaded screw 8 has two external threads with opposite directions. Slider blocks 10 are threadedly connected to the two external threads of the double-threaded screw 8. A side rod is mounted on one side of each slider 10. 11. A through groove 12 for moving the side rod 11 is provided on the upright plate 3. Extension plates 13 are respectively provided at both ends of the rotating plate 6. A crossbar 14 is provided on one side of the extension plate 13. A slot is provided on the crossbar 14. A stop bar 15 is also included. One end of the stop bar 15 is located inside the slot and is rotatably connected to the crossbar 14. An elastic member 16 is also included. Both ends of the elastic member 16 are respectively provided with through holes. The elastic member 16 is installed on the side rod 11 and the crossbar 14 through the through holes at both ends. When the elastic member 16 is sleeved on the crossbar 14, the central axis of the stop bar 15 coincides with the central axis of the crossbar 14.

[0019] One end of the chemical fiber filament 2 passes over the top of the infeed spool 4, then passes under the lower of the two movable spools 7, then passes diagonally upwards over the other movable spool 7, and then passes under the bottom of the outfeed spool 5, thus completing the placement of the chemical fiber filament 2, and then waits to be wound up.

[0020] When winding the synthetic fiber 2, the corresponding winding device applies a traction force to the synthetic fiber 2. After being subjected to the force, the synthetic fiber 2 can drive the rotating plate 6 to rotate through the movable thread wheel 7. When the rotating plate 6 rotates, the elastic element 16 is stretched, and the elastic element 16 gives the rotating plate 6 the potential energy to return to its original position. Therefore, the passing synthetic fiber 2 can be kept taut. When the traction force is greater, the rotation angle of the rotating plate 6 is also greater, and the tension of the synthetic fiber 2 is higher. When the traction force of the synthetic fiber 2 decreases, it means that the tension of the synthetic fiber 2 decreases. At this time, the elastic element 16 will drive the rotating plate 6 to return to its original position. Since the length of the synthetic fiber 2 located between the inlet wheel 4 and the outlet wheel 5 gradually increases during the process of the rotating plate 6 returning to its original position, the loosening of the synthetic fiber 2 can be weakened in time, so that the synthetic fiber 2 can be kept in a relatively taut state.

[0021] When it is necessary to adjust the tightness of the elastic element 16, the rotating wheel 9 can be rotated to drive the double threaded screw 8 to rotate. Through the threaded connection between the double threaded screw 8 and the two sliders 10, the two sliders 10 can be moved closer or further apart, thereby changing the distance between the two side rods 11 and thus controlling the stretching degree of the elastic element 16. When the distance between the two side rods 11 increases, the stretching degree of the elastic element 16 increases, and vice versa. By changing the stretching degree of the elastic element 16, it can be adapted to different strengths of yarn. For yarns with higher strength, the stretching degree of the elastic element 16 is greater, and for yarns with lower strength, the stretching degree of the elastic element 16 is smaller.

[0022] The stop lever 15 can restrict the threads inside the movable spool 7, thereby reducing the probability of the chemical fiber filament 2 jumping out of the movable spool 7. When replacing the elastic element 16, one end of the elastic element 16 can be moved to the outside of the rotational connection point between the stop lever 15 and the crossbar 14, and then the stop lever 15 can be rotated to increase the distance between the stop lever 15 and the movable spool 7, so that one end of the elastic element 16 can be easily removed from the stop lever 15. After the elastic element 16 is replaced, one end of the elastic element 16 is located inside the rotational connection point between the stop lever 15 and the crossbar 14, so that the stop lever 15 can play the role of restricting the threads inside the movable spool 7.

[0023] Furthermore, the outer surface of the stop bar 15 is provided with two protrusions 17, which further reduces the probability of the chemical fiber filament 2 jumping off the movable reel 7. At the same time, the through hole of the elastic element is also elastic, and the protrusions 17 will not affect the elastic element passing through the stop bar 15. Moreover, when the elastic element is in use, the protrusions 17 can also restrict the elastic element 16, preventing the elastic element 16 from falling off the stop bar 15 and the crossbar 14.

[0024] Furthermore, a protective shell 18 is provided on one side of the upright plate 3, and a double threaded screw 8 and a slider 10 are located between the protective shell 18 and the upright plate 3. The slider 10 can move along the protective shell 18.

[0025] Furthermore, the upright plate 3 is provided with an anti-torsion plate 19, and the thread feed wheel 4 is located below the anti-torsion plate 19, which can improve the stability of the upright plate 3. At the same time, part of the anti-torsion plate 19 can also prevent the chemical fiber filament 2 from jumping out of the thread feed wheel 4.

[0026] Furthermore, the base 1 is provided with a waist hole 20, and a reinforcing plate 21 is provided between the base 1 and the upright plate 3. The base 1 can be installed through the waist hole 20 and bolts, and the reinforcing plate 21 can further provide stability to the upright plate 3.

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.
