[0048] Specifically, it slides into the required position along the outer wall of the second rotating column 26. During the sliding process, the inner wall of the paper rope winding drum 27 contacts the outer wall of the block 36. At this time, the block 36 is forced to move downward, thereby prompting the sliding column 33 to slide inside the second fixed block 32, while causing the spring 35 to contract. The sliding column 33 here has a fixing effect on the block 36, and the sliding column 33 has a sliding effect on the spring 35. While the sliding column 33 slides inside the second fixed block 32, it also prompts the limit block 34 to slide inside the second fixed block 32. The limit block 34 here has a limiting effect on the sliding column 33. When the paper rope winding drum 27 is installed to the required position, the block 36 is no longer subjected to external pressure, so that the spring 35 rebounds and drives the block 36 and then drives the sliding column 33 and the limit block 34 to move upward, thereby ensuring that the position and angle of the paper rope winding are always kept stable.

[0049] The implementation principle of the embodiment of the present application is as follows: when the paper rope machine is needed, first, before the paper rope passes through the limit strip 37, a single strand of paper rope is passed through the inside of the elastic cylinder 14 respectively. After the multi-strand paper rope starts to be wound, if the tightness of the paper rope needs to be adjusted, it is only necessary to turn the knob 3. The rotation of the knob 3 inside the cylinder 1 drives the rotating rod 2 to rotate. The rotation of the rotating rod 2 drives the horizontal bevel gear 4 to rotate, thereby prompting the vertical bevel gear 7 to drive the round rod 6 to rotate on the lower surface of the internal top block 5 of the cylinder 1, and at the same time drives the turntable 8 to rotate on the inner wall of the fixed disk 10. When the turntable 8 rotates on the inner wall of the fixed disk 10, it prompts the first fixed column 12 to slide on the inner wall of the slide groove 9, so that the first fixed column 12 pushes the sliding column 13 to slide on the inner wall of the circular groove 11, and the sliding column 13 slides At the same time, the inner wall of the circular groove 11 drives the elastic tube 14 to move. Here, the moving distance of the elastic tube 14 can be adjusted according to the required tightness, so as to achieve the effect of conveniently and quickly adjusting and maintaining the tightness of the paper rope in the twisting process, and then the strength and firmness of the paper rope can be flexibly controlled according to specific needs. The paper rope first passes through the elastic tube 14 and then through the limit bar 37. After passing through the limit bar 37, it passes through the rotating tube 39 connected to the inner wall of the rotating frame 38, and finally is wound around the outer wall of the paper rope winding tube 27, and the motor 40 inside the outer box 28 is started. The rotation of the motor 40 drives the third rotating column 29 to rotate, and then drives the first gear 30 to rotate. The rotation of the first gear 30 drives the second gear 31 to rotate, and then drives the second rotating column 26 When rotating inside the support frame 21, it also rotates on the inner wall of the rotating groove 23. When the winding is completed, it is only necessary to lift the fixed plate 16 to slide out of the inner wall of the rotating groove 23, so that the rotating block 25 can rotate on the outer wall of the second fixed column 24. At this time, the paper rope winding drum 27 that has been wound can be replaced, so as to achieve the effect of quickly replacing the paper rope winding drum 27, reducing production downtime and improving production efficiency. When the new paper rope winding drum 27 is reinstalled, it slides into the required position along the outer wall of the second rotating column 26. During the sliding process, the inner wall of the paper rope winding drum 27 contacts the outer wall of the block 36. At this time, the block 36 is forced to move downward, thereby causing the sliding column 33 to slide inside the second fixed block 32, while the spring When the paper rope reel 27 is installed to the required position, the clamping block 36 is no longer subjected to external pressure, so that the spring 35 rebounds and drives the clamping block 36, and then drives the sliding column 33 and the limiting block 34 to move upward, so as to ensure that the position and angle of the paper rope reel are always kept stable, thereby helping to make the paper rope winding neat and uniform, preventing uneven tightness of the paper rope, and maintaining the quality and consistency of the paper rope winding. The paper rope machine can not only achieve the effect of conveniently and quickly adjusting and maintaining the tightness of the paper rope during the twisting process, but also flexibly control the strength and firmness of the paper rope according to specific needs.In addition, it can also achieve the effect of quickly replacing the winding drum, reducing production downtime and improving production efficiency. It can also ensure that the position and angle of the paper rope winding are always stable, which helps to make the paper rope winding neat and uniform, prevent uneven tightness of the paper rope, and maintain the quality and consistency of the paper rope winding.
