[0028] Embodiment 2

[0029] The main difference from the first embodiment is:

[0030] The polyester fully drawn yarn production equipment based on the reduced drawing process, the traction mechanism 2 includes an adjusting box 21 installed on the top of the workbench 1, the adjusting box 21 is slidably connected with an adjusting rod 22 inside, one end of the adjusting rod 22 is fixedly connected with an adjusting block 23, the bottom of the inner cavity of the adjusting box 21 is also installed with a slide rail, the adjusting block 23 slides on the surface of the slide rail, the top of the adjusting block 23 is fixedly connected with a clamping rod 24, the bottom of the inner cavity of the adjusting box 21 is provided with a linkage component 6, the adjusting box 21 is internally slidably connected with a mounting block 25, the mounting block 25 slides on the top of the adjusting box 25, the mounting block 25 is internally rotatably connected with a traction roller 26, the surface of the mounting block 25 is provided with a clamping groove 27, the inner surface of the clamping groove 27 is clamped with one end of the clamping rod 24, the front side of the inner wall of the adjusting box 21 is fixedly connected with an adjusting spring 28, the adjusting spring 28 is not affected by external force, so that one end of the clamping rod 24 is always clamped with the inside of the clamping groove 27, and one end of the adjusting spring 28 is clamped with the adjusting block 23 The adjusting block 23 is fixedly connected to one side of the adjusting box 21, and the linkage assembly 6 includes a linkage plate 61 rotatably installed at the bottom of the inner cavity of the adjusting box 21. The two ends of the linkage plate 61 are rotatably connected with linkage rods 62. One end of the linkage rod 62 is rotatably connected to the inside of the adjusting block 23. By pulling the adjusting rod 22, the adjusting block 23 is driven to slide, so that the adjusting spring 28 is compressed. The sliding of the adjusting block 23 makes one end of the front linkage rod 62 rotate inside the adjusting block 23, and the other end of the adjusting rod 22 rotates at one end of the linkage plate 61, so that the linkage plate 61 starts to rotate. The rotation of the linkage plate 61 makes the adjusting blocks 23 on both sides slide synchronously on the opposite sides, so that one end of the clamping rod 24 slides from the inner surface of the clamping groove 27. By directly pulling the adjusting rod 22, the mounting block 25 and the traction roller 26 can be quickly disassembled, which is convenient for quickly replacing the traction roller 26 according to different production environments. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] First, the polyester thread is passed from under the traction roller 26 on the left side of the top of the workbench 1, and then passes through the surface of the adjusting roller 315, and passes out from under the traction roller 26 on the right side of the top of the workbench 1. When the polyester thread is in the process of fully stretching the thread, the stretching force of the adjusting roller 315 on the polyester thread is monitored in real time by the pressure sensor 42. If the stretching force of the adjusting roller 315 on the thread exceeds the preset value, the controller monitors the stretching force of the adjusting roller 315 on the thread according to the pressure sensor 42, thereby controlling the operation of the drive motor 321, and the drive motor 321 drives the screw rod 322 to rotate. The rotation of the screw rod 322 causes the moving block 323 and the sliding block 324 to slide synchronously, so that the sliding block 324 slides on the inner surface of the sliding groove 5, and the sliding of the sliding block 324 causes the connecting plate 313 and the supporting plate 314 to slide. 2. The heights of the lifting rod 314, the concave block 41, the pressure sensor 42, the connecting block 43 and the adjusting roller 315 change until the tensile force of the adjusting roller 315 on the silk thread is restored to the preset value, so that the tensile tension of the silk thread can be timely and accurately regulated. The adjusting block 23 is driven to slide by pulling the adjusting rod 22, so that the adjusting spring 28 is compressed. The sliding of the adjusting block 23 causes one end of the front linkage rod 62 to rotate inside the adjusting block 23, and the other end of the adjusting rod 22 rotates at one end of the linkage plate 61, so that the linkage plate 61 starts to rotate. The rotation of the linkage plate 61 causes the adjusting blocks 23 on both sides to slide synchronously on opposite sides, so that one end of the clamping rod 24 slides from the inner surface of the clamping groove 27, thereby realizing the quick disassembly of the mounting block 25 and the traction roller 26.
