[0042] The working principle of the utility model is as follows: Reset: the station switching stepper motor drives the outer edge rotor 2 to rotate so that the front end fork-shaped material reel shaft 27 rotates to the first station (material taking position), and the double servo motor drives the ball spline screw 24 to return to the original position, and the front end fork-shaped reel shaft 27 is automatically parallel to the plane of the incoming shoe cover;

[0043] Feeding: The point-break plastic shoe covers produced by the shoe cover machine are pulled in synchronously with the linear speed of the shoe cover machine through the feeding traction roller 5 in front of the machine installation panel and pressed and sent to the winding rod. A material shortage detection sensor 16 is installed between the feeding traction roller 5 and the fork-shaped winding shaft 27 of the first station. When the material is broken or insufficient, the machine program automatically controls to stop winding and suspend the operation of the shoe cover machine;

[0044] Retrieving: At the first station, a set of double servo core combination controls the ball spline screw 24 to drive the forked material reel 27 at the front end to complete the retrieving action. The position-controlled servo motor moves the ball spline screw 24 from the origin position to the retrieving position, and the forked notch at the front end of the forked material reel 27 inserts the shoe cover;

[0045] Coiling: One of the two servo motors in a dual-servo core combination controls the spline of the ball spline screw 24 in a torque control mode to drive the fork-shaped coiling shaft 27 at the front end to make circular motion, and the other servo motor controls the ball spline screw 24 in a position control mode to drive the fork-shaped coiling shaft 27 at the front end to make translational motion. When the coiling shaft rotates, the fork-shaped notch winds the shoe cover around the fork-shaped coiling shaft 27 in a progressive spiral curve motion;

[0046] Station switching: After the coiling starts, while one group of coiling continues, the station switching stepper motor drives the outer rotor 2 to rotate, and moves the first group of coiling shafts in the process of coiling to the second station. At this time, the planetary traction driven roller 13 flattens the shoe covers that have been pulled but not yet wound into the first group of coiling shafts, and cooperates with the feed traction roller 5 to clamp the shoe covers that have not been wound into the coiling shafts to feed them into the first group of coiling shafts synchronously with the linear speed of the shoe cover machine, and continue to coil until the material is full; at the same time, the second group of spare fork-shaped coiling shafts 27 move to the first station; when the station switching is completed, the second group of coiling shafts extend to the material taking position, so that the front end fork notch is aligned with the shoe cover, and the notch of the fork-shaped coiling shaft 27 is parallel to the running plane of the shoe cover, which does not affect the shoe cover being coiled by the first group of coiling shafts through the fork-shaped notch at the front end of the second group of coiling shafts.

[0047] Coiling is completed: When the single-chip main control board detects that the number of shoe covers that have been rolled is complete, the shoe cover break position is located between the second set of coiling shafts and the feed traction roller 5. The second set of coiling shafts are started to roll the material in a progressive spiral motion. The second set of coiling shafts and the feed traction roller 5 and the planetary traction driven roller 13 clamp the second set of coiling shafts to tear the shoe covers from the break position, and the second set of coiling shafts enter the coiling step. Then the first set of coiling shafts roll up the remaining shoe covers and stop.

[0048] Material unwinding: After a set of coiling is completed, the position control servo motor controls the ball spline screw 24 to move the fork-shaped coiling shaft 27 backward to the origin position, and the rolled conical shoe sleeve is ejected from the fork-shaped notch of the current fork-shaped coiling shaft 27 and falls on the rear conveyor belt. The material unwinding is completed. After the unwinding process is completed, the station switching moves the second set of coiling shafts to the second station to continue coiling, and the first set of coiling shafts returns to the first station to prepare for material unwinding.

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

[0050] In summary, the utility model has high efficiency and good stability in shoe cover rolling and high automation, less manual participation in the shoe cover processing process, reduced labor intensity, and further improved shoe cover packaging efficiency.

[0051] The above specific implementations do not constitute a limitation on the protection scope of the present disclosure. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
