[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] A twisting device for producing chemical fiber ropes, such as Figures 1 to 4 As shown, it includes a bottom shell 1, two sets of front wire holes 2 are fixedly connected to the side wall of the bottom shell 1, a first wire hole 3 is opened at one end of the bottom shell 1 close to the front wire hole 2, and a second wire hole 4 is opened at the other end of the bottom shell 1. Two sets of tensioning mechanisms 5 are fixedly connected to the inner wall of the bottom shell 1;

[0027] Each set of tensioning mechanisms 5 includes two sets of rotating arms 501, which are rotatably connected to the bottom end of the inner wall of the bottom shell 1. The rotating arms 501 are provided with torsion springs at the connection with the bottom shell 1. The two ends of each set of rotating arms 501 are respectively slidably connected to a set of sliders 502, and a rubber wheel 504 is rotatably connected between the two end sliders 502 at the same end. The top of each set of sliders 502 is fixedly connected to a set of pressure springs 503. Two sets of guide wheels 505 are rotatably connected between the two sets of rotating arms 501. The two sets of guide wheels 505 are respectively located next to the two sets of rubber wheels 504. The side wall of the bottom shell 1 is installed with a first motor 7.

[0028] Pass the two sets of chemical fiber ropes 6 through the two sets of front wire holes 2, then put the two sets of chemical fiber ropes 6 side by side through the first wire hole, and then tie the chemical fiber ropes 6 as Figure 1 In the state shown in the figure, the two sets of tensioning mechanisms 5 are rotated respectively, and then the chemical fiber rope 6 is passed through the second wire hole 4, and finally the end of the chemical fiber rope 6 is fixed on the outer wall of the reel 805. During the twisting process of the chemical fiber rope 6, if the chemical fiber rope 6 is in a relatively loose state, the torsion spring drives the rotating arm 501 to rotate, so that the rotating arm 501 drives the guide wheel, thereby folding the chemical fiber rope 6, so that the chemical fiber rope 6 is in a Figure 1 In the state, when the chemical fiber rope 6 is over-tightened, the guide wheel is pushed by the chemical fiber rope 6, thereby driving the rotating arm 501 to flip from the oblique state to the horizontal direction and twisting the torsion spring to prevent the chemical fiber rope 6 from being over-tightened, so that the chemical fiber rope 6 is always kept at a reasonable tension.

[0029] Please refer to Figure 1 、 Figure 3 and Figure 4 The output end of the first motor 7 is fixedly connected to the twisting mechanism 8, and the twisting mechanism 8 includes a bracket 801, which is fixedly connected to the output end of the first motor 7. The side wall of the bracket 801 is fixedly connected to the second motor 802. The output end of the second motor 802 is fixedly connected to the connecting column 803. The inner wall of the connecting column 803 is slidingly sleeved with a latch 804. One end of the latch 804 extends to the outside of the connecting column 803. The end of the latch 804 located outside the connecting column 803 is fixedly connected to a reel 805. The inner wall of the connecting column 803 slides Two groups of limiting balls 806 are connected, and a limiting groove is provided on the outer wall of the pin 804, and the limiting groove matches the size of the limiting ball 806. The outer wall sliding sleeve of the connecting column 803 is provided with a sliding sleeve 807, and the inner wall of the sliding sleeve 807 is provided with two groups of grooves 808, and the size of the groove 808 matches the size of the limiting ball 806. The side wall of the sliding sleeve 807 is fixedly connected with a return spring 809, and the return spring 809 is sleeved on the outside of the connecting column 803. The end of the return spring 809 is fixedly connected to the side wall of the bracket 801, and the cross-section of the pin 804 is rectangular.

[0030] The first motor 7 drives the bracket 801 to rotate, thereby causing the entire twisting mechanism 8 to rotate, causing the reel 805 to twist the chemical fiber rope 6. During this process, the second motor 802 drives the connecting column 803 to rotate, causing the connecting column 803 to drive the latch 804 to rotate, and the latch 804 drives the reel 805 to rotate, thereby winding the chemical fiber rope 6. When the latch 804 is inserted into the connecting column 803, the return spring 809 is compressed by pushing the sleeve 807, so that the groove 808 inside the sleeve 807 is aligned with the limiting ball 806, and then the latch 804 is inserted, so that the latch 804 pushes the limiting pin, so that the limiting ball 806 slides into the groove 808. When the latch 804 is fully inserted into the connecting column 803, the limiting groove is aligned with the limiting ball 806, and then the sleeve 807 is released. The return spring 809 rebounds and pushes the sleeve 807 to reset. At this time, the position of the groove 808 is reset, thereby pushing the limiting ball 806 to reset, so that the limiting ball 806 slides into the limiting groove, so that the pin 804 is blocked by the limiting ball 806, and the limiting ball 806 is blocked by the inner wall of the sleeve 807 and cannot be separated from the limiting groove, so that the pin 804 and the connecting column 803 cannot be separated. When the pin 804 needs to be pulled out, the sleeve 807 is pushed again so that the sleeve 807 drives the groove 808 to align with the limiting ball 806. At this time, the pin 804 is pulled out from the inside of the connecting column 803. In this process, the pin 804 drives the limiting groove to move, so that the limiting ball 806 is pushed and slides into the inside of the groove 808. Therefore, the limiting ball 806 cannot block the pin 804 at this time, thereby realizing the installation and disassembly of the reel 805.

[0031] During use, the chemical fiber rope 6 passes through the inside of the two sets of tensioning mechanisms 5, so that the tensioning mechanisms 5 tighten the chemical fiber rope 6, so that during the twisting process, the chemical fiber rope 6 always remains in a straight state, thereby avoiding the phenomenon of knotting and entanglement of the chemical fiber rope 6, improving the quality of the rope, and avoiding inconvenience in subsequent use. The parts not involved in the device are the same as the existing technology or can be implemented using the existing technology.
