Detailed Implementation

[0020] The following description uses the driving mechanism of the four-part yarn tray as an example to illustrate the translation driving mechanism of the yarn tray provided in this application.

[0021] Please see Figure 1 and Figure 2 The multi-sliding yarn tray translation drive mechanism provided in this application includes a drive shaft 1, a first sliding block 2, a second sliding block 3, a third sliding block 4, and a fourth sliding block 5; a first screw section 11, a second screw section 12, a third screw section 13, and a fourth screw section 14 are provided on the drive shaft 1; the first sliding block 2, the second sliding block 3, the third sliding block 4, and the fourth sliding block 5 are respectively threadedly connected to the first screw section 11, the second screw section 12, the third screw section 13, and the fourth screw section 14; the lead ratio of the fourth to the first screw section satisfies the following: 4:3:2:1.

[0022] The multi-section yarn tray translation drive mechanism also includes a bracket 7 and a guide rod 8; the drive shaft 1 is mounted on the bracket 7 via bearings, and the guide rod 8 is fixedly mounted on the bracket 7. The first sliding block 2, the second sliding block 3, the third sliding block 4, and the fourth sliding block 5 are slidably mounted on the guide rod 8 through their own apertures.

[0023] The multi-section yarn tray translation drive mechanism also includes a drive motor 6, a transmission belt, a drive wheel, and a driven wheel; the drive wheel is connected to the drive motor, and the driven wheel is connected to the drive shaft; the drive wheel and the driven wheel are connected by the transmission belt. When the drive motor 6 starts, it can drive the drive shaft 1 to rotate, thereby driving the first sliding block 2, the second sliding block 3, the third sliding block 4, and the fourth sliding block 5 to slide on the guide rod 8 according to their respective leads.

[0024] Guide P h = (linear velocity of the sliding block) v ) ÷ (Speed ​​of the drive motor) n ).

[0025] Assuming the drive motor 6 rotates at 600 rpm, and the leads of the fourth to first screw sections are 20, 15, 10, and 5 mm / rpm respectively; the linear velocity of the first sliding block 2 is: v=n×P h = 600 rev / min ×5 mm / rev =3000 mm / min =50 mm / s The linear velocities of the second sliding block 3, the third sliding block 4, and the fourth sliding block 5 are 100, 150, and 200 respectively. mm / s For every second that the drive motor 6 rotates, the first to fourth sliding blocks move by 5, 10, 15, and 20 units respectively. cm During implementation, the number and size of the screw section on the drive shaft, as well as the lead of each screw section, can be flexibly determined based on the number of pulls at the machine head, the size of the yarn support plate and the yarn ball.
