The nylon fiber is squeezed and moved dynamically. The outer wall of the rear side of the driving roller 3 is fixedly connected with an adjusting component. The adjusting component includes a driving wheel 71, which drives the driven wheel 5 through the belt 6, thereby driving the driving roller 3 and the driven roller 4 to rotate. The front end of the driving wheel 71 is fixedly connected to the rear side of the driving roller 3, and the inner wall of the driving wheel 71 is slidably connected with a slider 72. The slider 72 can slide out from the inner wall of the driving wheel 71, thereby adjusting the rotation radius of the belt 6 on the driving wheel 71 and changing the rotation speed of the driving wheel 71, thereby quickly controlling the stretching rate of the fiber. The rear side of the bottom end of the slider 72 is set as an inclined arc surface, and the inclined arc surface can be completely fitted with the outer wall of the limiting block 74.

The rotating rod 76 is rotated to facilitate the adjustment of multiple groups of sliders 72. The sliders 72, limit blocks 73 and slide grooves 75 are arranged in multiple groups and are evenly distributed with the center point of the limit block 74 as the axis. The stability of the device can be improved by setting multiple groups. The inner wall of the top of the slider 72 is provided with an anti-slip strip, which increases the friction between the slider 72 and the inner wall of the belt 6 to prevent the belt 6 from sliding during the adjustment process. The outer wall of the transmission wheel 71 is connected to the belt 6 for transmission, and the left side of the belt 6 is connected to the driven wheel 5 for transmission. A driving motor is fixedly installed on the rear side of the driven wheel 5. The bottom end of the driving motor is fixed to the top of the base 1, and the front end of the driven wheel 5 is fixedly connected to the rear side of the driven roller 4. When the transmission wheel 71 rotates, the driven wheel 5 and the driven roller 4 are driven to rotate together through the belt 6, thereby realizing the extrusion and stretching movement of the nylon fiber.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The inner wall of the support plate 2 is provided with a temperature regulating component, which includes a moving box 81. The moving box 81 is provided with a heat-insulating material and a heating tube is provided inside for stretching the nylon fiber. It is an existing structure and can be implemented by technicians in this field. Since it is an existing technology, it will not be described in detail in this case. The front and rear ends of the moving box 81 are slidably connected to the inner wall of the support plate 2. A heat outlet hole 82 is provided at the top of the moving box 81 for releasing heat to the fiber. A heat insulating plate 83 is slidably connected to the inner wall of the moving box 81 near the bottom of the heat outlet hole 82. The heat insulating plate 83 is also provided with a heat insulating material. The top of the heat insulating plate 83 is provided with a hole that is the same as the heat outlet hole 82. The heat insulating plate 83 is moved through the heat insulating plate 83. , so that the heat insulation board 83 covers the heat outlet hole 82, so as to control the heat dissipation rate, thereby improving the stretching effect and performance of the nylon fiber. The front end of the heat insulation board 83 is rotatably connected with a threaded rod 84, and the position of the heat insulation board 83 is controlled by rotating the threaded rod 84. The rear outer wall of the threaded rod 84 is threadedly connected to the inner wall of the moving box 81. The moving box 81 is symmetrically arranged with two groups. The upper and lower ends of the nylon fiber can be heated simultaneously through the two groups of moving boxes 81. The rear sides of the two groups of moving boxes 81 are threadedly connected with double-twisted screws 85. The bottom ends of the double-twisted screws 85 are rotatably connected to the inner wall of the top end of the base 1. The distance between the two groups of moving boxes 81 and the nylon fiber is accurately adjusted by the double-twisted screws 85.

[0034] Working principle: During use, when it is necessary to adjust the stretching rate of the nylon fiber, the crank handle 77 is turned to drive the rotating rod 76 to rotate on the inner wall of the transmission wheel 71 through the threaded groove, driving the limiting block 74 to move forward, and at the same time, the inclined arc surface on the multiple groups of sliders 72 is squeezed through the inclined surface of the limiting block 74. At the same time, the multiple groups of limit blocks 73 slide on the inner walls of the multiple groups of slide grooves 75 to limit the sliders 72 in time. After being squeezed, the multiple groups of sliders 72 will move along the outer side of the inner wall of the transmission wheel 71, so that the multiple groups of sliders 72 support the belt 6, thereby changing the rotation radius of the belt 6, so that the rotation rate between the transmission roller 3 and the driven roller 4 is changed, thereby adjusting the stretching rate of the nylon fiber.

[0035] When the temperature of the nylon fiber needs to be adjusted during stretching, the double-twisted screw 85 is first rotated to adjust the distance between the two groups of moving boxes 81. At this time, the threaded rod 84 is rotated to make the insulation board 83 slide on the inner wall of the moving box 81, thereby blocking the heat outlet hole 82, achieving control of the heat dissipation rate, thereby improving the stretching effect and performance of the nylon fiber.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
