[0028] 2. According to the present invention, when a row of rubber anti-slip sleeves on the front side is full of yarns, the staff presses the button on the control panel. At this time, the output shaft of the servo motor rotates half a circle, realizing the automatic rotation of the yarn placing rack, and the row of yarns after rotation is directly behind, which is convenient for the staff to place the yarns to be placed on the side corresponding to the row of yarns, so that the force on the yarn placing rack is more uniform, avoiding serious uneven force on the yarn placing rack; when the detection button is pressed, when the staff presses the button on the control panel again, the output shaft of the servo motor can rotate half a circle; when the detection button is not pressed, when the staff presses the button on the control panel again, the output shaft of the servo motor remains stationary, avoiding the row of yarns after placement from moving to the front side again, which is beneficial to improving the adjustment effect of the yarn placing rack;

[0029] In addition, when the front and rear rows of rubber anti-slip sleeves are full of yarn, the staff rotates the yarn placement rack forty-five degrees clockwise or counterclockwise by adjusting the handle, and the output shaft of the servo motor is in a powered and non-rotating state under the control of the control panel. When the yarn placement rack rotates forty-five degrees clockwise or counterclockwise, the yarn placement rack pushes the four movable positioning rods to automatically move upward. When the yarn placement rack rotates to an appropriate angle, the four movable positioning rods are automatically reset under the action of four reset springs B; when the staff rotates the adjustment handle forty-five degrees clockwise or counterclockwise, one of the pressing plates can automatically press the detection button. At this time, when the staff presses the button on the control panel again, the output shaft of the servo motor can rotate half a circle. Under the premise of achieving symmetrical placement of the yarn, there will be no misadjustment, thereby ensuring the adjustment accuracy of the yarn placement rack.
