[0042] The working principle of the utility model is as follows: reset: the outer rim rotor 2 is rotated by a station switching stepping motor to make the front end of the fork-shaped material winding shaft 27 rotate to the first station (material taking position), the double servo motor is driven to retreat to the original position of the ball spline rod 24, and the front end of the fork-shaped material winding shaft 27 is automatically parallel to the plane of the incoming shoe sleeve;

[0043] Feeding: the point breaking type plastic shoe sleeve produced by a shoe sleeve machine is drawn into the material winding rod through the feeding traction roller 5 in front of the installation panel of the machine at the same speed as the linear speed of the shoe sleeve machine, and the shoe sleeve is pressed and sent in, a material shortage detection sensor 16 is arranged between the feeding traction roller 5 and the fork-shaped material winding shaft 27 in the first station, when the material is broken or the material is insufficient, the material winding is automatically controlled to stop by the program of the machine, and the operation of the shoe sleeve machine is also stopped.

[0044] Material taking: in the first station, a group of double servo core combination control ball spline screw 24 drives the front end of the fork-shaped material winding shaft 27 to complete the material taking action. The position control servo motor moves the ball spline screw 24 from the original position to the forward translation position. The front end of the fork-shaped material winding shaft 27 forks into the sleeve.

[0045] Material winding: a group of double servo core combination controls the ball spline screw 24 with torque control mode to drive the front end of the fork-shaped material winding shaft 27 to do circular motion. Another servo motor controls the ball spline screw 24 with position control mode to drive the front end of the fork-shaped material winding shaft 27 to do translation motion. When the material winding shaft rotates, the fork-shaped notch winds the sleeve on the fork-shaped material winding shaft 27 in a gradual spiral curve motion.

[0046] Station switching: after the material winding starts, a group of material winding actions continue while the station switching stepper motor drives the outer rotor 2 to rotate, moving the first group of material winding shafts in progress to the second station. At this time, the planetary traction driven roller 13 flattens the sleeve that has not been wound into the first group of material winding shafts and cooperates with the feeding traction roller 5 to clamp the sleeve that has not been wound into the material winding shaft to synchronize with the linear speed of the sleeve machine to feed into the first group of material winding shafts, continuously winding until full.

[0047] Material winding completion: when the single-chip microcomputer main control board detects that the winding of the sleeve is completed, it positions the sleeve point breaking position between the second group of material winding shafts and the feeding traction roller 5. It starts the second group of material winding shafts to make a gradual spiral motion. The second group of material winding shafts and the feeding traction roller 5 clamp the second group of material winding shafts to cooperate to tear the sleeve from the point breaking position. The second group of material winding shafts enters the material winding step. Then the first group of material winding shafts winds the residual sleeve and stops.

[0048] Material returning: after a group of material winding is completed, the position control servo motor controls the ball spline screw 24 to move the fork-shaped material winding shaft 27 backward to the original position. The wound conical sleeve cylinder is ejected from the fork-shaped notch of the current fork-shaped material winding shaft 27 and falls on the rear end of the conveying belt. The material returning is completed. After the material returning process is completed, the station switching moves the second group of material winding shafts to the second station for continuous winding, and the first group of material winding shafts returns to the first station for material taking.

[0049] The above steps are repeated to complete the continuous production process.

[0050] The utility model discloses, not only the efficiency of shoe cover winding is high, stability is good, and automation degree is high, and the artificial participation is less in the shoe cover processing process, reduces the labor intensity, and the packaging efficiency of shoe cover is further improved.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
