[0043] See also Figure 4-5 A pair of extension arms are fixedly connected to the auxiliary traction device 5, and a movable roller group 6 is rotatably connected between the pair of extension arms. The movable roller group 6 includes a pair of turntables 601, and a pair of guide rollers 602 are slidably connected between the pair of turntables 601. A bidirectional electric push rod matching the pair of guide rollers 602 is fixedly connected to the turntable 601. A stepper motor for driving the movable roller group 6 to rotate is installed on the auxiliary traction device 5. The stepper motor is installed in the power box 502. A transmission mechanism is set between the stepper motor and the movable roller group 6 to ensure the rotation of the movable roller group 6. A suitable stepper motor is selected by a technician in this field for installation.

[0044] The traction wheel 2 is detachably mounted on the mounting platform 1, a retractable extension shaft is fixedly connected to the power output end of the stepper motor, and a slot matching the extension shaft is provided at the side end of the central axis of the traction wheel 2, so as to facilitate the disassembly, replacement and maintenance of the traction wheel 2.

[0045] See also Fig.10 , and also includes a traction control system, the traction control system includes a controller, and the traction motor, the longitudinal guide rail 3, the transverse guide rail 4, the auxiliary traction device 5 and the movable roller group 6 are all connected to the controller signal;

[0046] A drum shell is rotatably connected to the outer wall of one of the guide rollers 602, and a hysteresis brake matching the drum shell is arranged on the turntable 601. The hysteresis brake is connected to the controller signal, and the resistance of the drum shell is increased by the hysteresis brake to adjust the resistance encountered by the spinning when being pulled. By accurately controlling the hysteresis brake, it is convenient to accurately adjust the traction force experienced by the spinning.

[0047] A thin film pressure sensor is laid on the surface of one of the guide rollers 602, and the thin film pressure sensor is connected to the controller signal. The interaction force between the spinning and the guide roller 602 is detected by the thin film pressure sensor to assist in monitoring the traction force of the spinning.

[0048] It is possible to achieve micro-adjustment and micro-calibration of the traction force of the spinning during the traction process, ensuring that the traction force of the spinning is maintained within the required range during the traction and winding process of the spinning, and to facilitate micro-pulling and clamping of the spinning during the traction process, thereby conveniently meeting different traction requirements of the spinning during the traction process.

[0049] See also Figure 7-9 , a traction device for spinning production, and its use method is:

[0050] S1, firstly, the textile passes through the movable roller group 6 and is connected to the traction wheel 2, and then the traction wheel 2 is started to carry out spinning traction and winding;

[0051] S2, adjusting the movable roller group 6, and fine-tuning the traction force on spinning by changing the position of a pair of guide rollers 602;

[0052] In this embodiment, the traction force of spinning is adjusted by rotating the movable roller group 6 as a whole. The relationship between the rotation angle of the movable roller group 6 and the change of the traction force of spinning can be obtained by those skilled in the art through experiments and calculations.

[0053] Specifically, the maximum rotation angle of the movable roller set 6 is: the rotation angle of the movable roller set 6 when any guide roller 602 rotates to contact the laser emitted by the laser sensor 503;

[0054] S3, during the adjustment process of the movable roller group 6, the transverse guide rail 4 is synchronously driven to move, so that the spinning input above the movable roller group 6 always remains vertical;

[0055] By ensuring that the spinning is always introduced into the movable roller group 6 in a vertical state, it is convenient to locate the direction of the traction force, so that when the movable roller group 6 is adjusted, it is not easy to cause the spinning to shake, and it is not easy to cause the traction force to fluctuate due to the change of the spinning line direction;

[0056] S4, after adjusting the movable roller group 6, the traction wheel 2 is restored to operate.

[0057] By adjusting the working state of the movable roller group 6, the spinning traction force can be adjusted and different traction effects can be achieved.

[0058] When the present solution is used, the spinning passes through the movable roller group 6 and is connected to the traction wheel 2, and the spinning is pulled by the rotation of the traction wheel 2; during the pulling process, when the spinning needs to be slightly pulled or offset adjusted, the traction wheel 2 can be slowed down or stopped, and a larger traction force change adjustment can be made when the traction wheel 2 is slowed down or stopped;

[0059] Smaller traction force changes can be achieved when the traction wheel 2 is operating normally through the cooperation of the movable roller group 6 and the auxiliary traction device 5;

[0060] At this time, the stepper motor can be controlled to drive the movable roller group 6 to rotate. During the rotation of the movable roller group 6, the transverse guide rail 4 is displaced, so that the guide roller 602 applies pressure to the spinning to adjust the spinning traction force; during the adjustment process, the auxiliary tractor 5 can be driven to move to ensure that it always enters the movable roller group 6 in a vertical state during the adjustment process; when the movable roller group 6 is finely adjusted, the spinning is not easily offset due to shaking;

[0061] It is possible to achieve micro-adjustment and micro-calibration of the traction force of the spinning during the traction process, ensuring that the traction force of the spinning is maintained within the required range during the traction and winding process of the spinning, and to facilitate micro-pulling and clamping of the spinning during the traction process, thereby conveniently meeting different traction requirements of the spinning during the traction process. Embodiment 2:

[0062] The present invention provides a traction device for spinning production, please refer to Figure 5 , wherein the components identical or corresponding to those in Example 1 are marked with the same reference numerals as those in Example 1. For the sake of simplicity, only the differences from Example 1 are described below. The difference between Example 2 and Example 1 is that:

[0063] When the movable roller group 6 is adjusted in step S2, when the axis between the pair of guide rollers 602 rotates to horizontal, the pair of guide rollers 602 approach each other and clamp the spinning;

[0064] A pair of guide rollers 602 are used to approach and clamp the spinning to fix the spinning. At this time, the spinning can be cut off below the movable roller group 6, and the traction wheel 2 can be replaced. After replacing the traction wheel 2, the pair of guide rollers 602 are separated, and the spinning continues to be released or the technician manually pulls the spinning. At this time, the technician can easily and quickly connect the spinning to the replaced traction wheel 2, so that when the traction wheel 2 is saturated or damaged, the traction wheel 2 can be quickly replaced without affecting the input spinning.

[0065] Optionally, the present embodiment can also adjust the pressure of clamping the spinning after clamping the spinning so that the clamped spinning can slide when being pulled; at this time, when the present embodiment is used to wind up the tail end of the input spinning, the movable roller group 6 can be rotated as a whole to make the movable roller group 6 wind up the tail end of the input spinning segment first, to ensure that the tail end of the input spinning is not easy to shake during the transportation process, and then use the traction wheel 2 to pull and wind up the spinning wound on the movable roller group 6, to ensure the stability of the tail end of the short spinning segment when winding up. Embodiment 3:

[0066] The present invention provides a traction device for spinning production, please refer to Figure 7 , wherein the components identical or corresponding to those in Example 1 are marked with the same reference numerals as those in Example 1. For the sake of simplicity, only the differences from Example 1 are described below. The differences between Example 3 and Example 2 are as follows:

[0067] When the movable roller set 6 is adjusted in step S2, the turntable 601 rotates at a set speed and a set angle and then resets, and repeats the set number of times at a specified time interval.

[0068] In this embodiment, the active roller group 6 is used to continuously pull the spinning, thereby achieving intermittent stretching of the spinning thread during the spinning thread pulling process.

[0069] Embodiment 4:

[0070] The present invention provides a traction device for spinning production, please refer to Figure 8 , wherein the components identical or corresponding to those in Example 1 are marked with the same reference numerals as those in Example 1. For the sake of simplicity, only the differences from Example 1 are described below. The difference between Example 2 and Example 1 is that:

[0071] In step S2 , when the movable roller group 6 is adjusted, one guide roller 602 approaches another guide roller 602 to achieve spinning pressure; the position change of the guide roller 602 is achieved by the operation of a bidirectional electric push rod between a pair of guide rollers 602 .

[0072] In this embodiment, the traction force of spinning is adjusted by changing the position of the guide roller 602, and the traction force can be adjusted by coordinating with the rotation of the movable roller group 6;

[0073] Since the position change and the movable roller group 6 can increase or reduce the pressure on the spinning, the range of traction adjustment in this embodiment is larger than that in embodiment 1.

[0074] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
