[0022] Reference Figures 1 to 4 As shown, an automatic shoe cover machine of the present invention comprises a conveying device 3 for conveying shoe covers 4, an opening device 5 for opening the shoe covers 4 and a releasing device 6 for releasing the shoe covers 4. The shoe covers 4 are arranged one by one on the conveying device 3. The shoe covers 4 are provided with a reserved opening for the opening device 5 to extend thereinto. The conveying device 3 conveys the shoe covers 4 one by one to a predetermined position. Two pairs of opening devices 5 are provided on both sides of the shoe cover machine for extending into the reserved opening of the shoe cover 4. The corresponding opening devices 5 arranged laterally are used to keep the shoe covers 4 laterally opened. The other pair of opening devices 5 can move along the front-rear direction of the shoe covers 4 for longitudinally opening the shoe covers 4. The releasing device 6 is used to release the shoe covers 4 from the opening devices 5 and put them on the outside of the shoes.

[0023] Reference Figure 1 , Figure 2 and Figure 3As shown, the shoe cover 4 is pre-connected with accessories, which are symmetrically arranged on the sides of the shoe cover 4, that is, one accessory is arranged on each side, and the accessories include a support block 402 arranged inside the shoe cover 4, and the support block 402 can adopt a square structure. The support block 402 is arranged adjacent to the elastic band on the opening of the shoe cover 4, and the support block 402 is used to produce a reserved opening at the opening position of the shoe cover 4, and the reserved opening can facilitate the subsequent opening device 5 to enter the shoe cover 4 and hook the elastic band (or rubber band) of the shoe cover 4. The support block 402 is fixed to the shaft, and the shaft is rotatably connected to the rotating part 401 so that the rotating part 401 can rotate relative to the shaft, and the rotating part 401 is arranged outside the shoe cover 4, and the rotating part 401 can be stuck in the conveying groove 301 of the conveying device 3.

[0024] Reference Figure 1 , Figure 2 As shown, the conveying device 3 includes a conveying groove 301, and the rotating parts 401 on both sides of the shoe cover 4 are restricted in the conveying grooves 301 arranged relatively parallel, and the shoe cover 4 moves along the conveying groove 301. A hole matching the shaft is provided in the middle of the conveying groove 301, and the two side walls of the hole can limit the rotating part 401 from leaving the conveying groove 301. The distance between the relatively arranged conveying grooves 301 is equivalent to the distance that the shoe cover 4 is stretched horizontally. The conveying groove 301 can be arranged horizontally or obliquely, and the shoe covers 4 are put into the conveying groove 301 one by one. The insertion port can be set at the upper part or the rear part of the shoe cover machine housing 1. When the shoe cover 4 is put into the conveying groove 301, it is not stretched longitudinally, the elastic band is not stretched or stretched a little, and the bottom of the shoe cover 4 sags due to gravity to keep the opening facing upward during the conveying process. The rotating part 401 is columnar and matches with the bottom of the conveying groove 301. The shoe cover 4 can be automatically moved down the slope by gravity, or an electric push rod can be set to push the shoe cover 4 to move. A conveyor belt can also be set in the area between the two conveying grooves 301, and the lower part of the shoe cover 4 is placed on the conveyor belt. When the shoe cover 4 moves, the conveyor belt moves synchronously.

[0025] The end of the conveying trough 301 cooperates with the rotating wheel mechanism, refer to Figure 1 , Figure 2 and Figure 3As shown, a groove 303 is provided on the rotating wheel, and one rotating part 401 is accommodated in the groove 303 each time. The conveying groove 301 cooperates with the groove 303 of the rotating wheel. When the groove 303 of the rotating wheel rotates to the outlet of the conveying groove 301, a shoe cover 4 enters the groove 303, and the rotating wheel continues to rotate. The groove 303 rotates with the shoe cover 4, and the wheel surface of the rotating wheel blocks the outlet of the conveying groove 301, and other shoe covers 4 remain in the conveying groove 301, so that one shoe cover 4 is taken out at a time. In this embodiment, the rotating wheel mechanism also includes a base 304 fixed on the bottom surface of the shoe cover machine housing 1, a disc 302 connected to both sides of the base 304 by an axis, the disc 302 is controlled to rotate by a motor, the disc 302 is provided with a cutout, the upper surface of the base 304 near the conveying groove 301 includes an arc segment 305, the upper surface of the base 304 and the cutout form a groove 303, the side of the base 304 away from the conveying groove 301 includes an elliptical arc segment 306, the rotating part 401 of the shoe cover is kept in the groove 303 when the circular arc segment runs, and when the disc 302 drives the shoe cover 4 to rotate to the elliptical arc segment 306, the elliptical arc segment 306 pushes the shoe cover 4 away from the groove 303 to a predetermined position, and the predetermined position is set on the connecting plate, and the connecting plate can extend to the rotating wheel mechanism area to support the bottom of the shoe cover 4. During this process, due to the gravity of the shoe cover 4 and the rotation of the rotating part 401 relative to the axis, the opening of the shoe cover 4 is always kept facing upward, and the square-structured support block 402 can also limit the opening of the shoe cover 4 from turning over.

[0026] Reference Figure 1 and Figure 4As shown, the stretching device 5 includes a first hook 501 arranged in pairs horizontally, and a second hook 502 arranged in pairs on one side of the first hook 501. The distance between the two second hooks 502 is equal to the distance that the shoe cover is stretched horizontally. The first hook 501 can adopt a cylinder structure or an electric lifting rod structure to achieve movement in the height direction. The first hook 501 is extended into the reserved opening. The positions of the two first hooks 501 correspond to the positions of the reserved opening. The two second hooks 502 are arranged on one side of the first hook 501 and connected to a cylinder that moves horizontally or in the front-to-back direction of the shoe cover 4 or are moved by gears, motors and other existing technologies. The second hook 502 enters the shoe cover 4 from the reserved opening and hooks the other side of the elastic band, and the shoe cover 4 is stretched open by movement. In order to smoothly hook the elastic band with the second hook 502, a slide plate 504 is provided below the second hook 502. A first protrusion 505 is provided at one end of the slide plate 504 near the predetermined position. A vertical surface 508 is provided on one side of the first protrusion 505 near the predetermined position, and a curved surface 507 is provided on the other side. The second hook 502 is connected to the moving bar 503. A second protrusion 506 cooperating with the first protrusion 505 is provided on the moving bar 503. The second protrusion 506 includes a curved surface 507 on one side near the predetermined position, and a vertical surface 508 cooperating with the first protrusion 505 on the other side. When the first protrusion 505 meets the second protrusion 506, one end of the second hook 502 arches upward to avoid hitting the side of the shoe cover 4. When the second protrusion 506 moves from one side of the first protrusion 505 to the other side, the second hook 502 changes from an arched state to a horizontal state. At this time, the second hook 502 is lowered into the reserved opening of the shoe cover 4. As the second hook 502 moves in the opposite direction, the second hook 502 hooks the elastic band and drives it to move. At this time, the vertical surfaces 508 of the first protrusion 505 and the second protrusion 506 cooperate, and the second hook 502 moves with the slide plate 504.

[0027] Reference Figure 1 and Figure 4As shown, the release mechanism includes a pedal 601, and an elastic member is arranged below the pedal 601. The elastic member can be a commonly used spring 7 or other structure. When in use, the foot enters from the reserved inlet 2 of the automatic shoe cover machine housing 1 and steps on the pedal 601. The pedal 601 can be restricted to vertical movement, such as through structures such as slide rails and sliding rods. The pedal 601 moves downward, so that the elastic band is subjected to a downward force, and the elastic band is released from the first hook 501 and the second hook 502, and shrinks to the foot to complete the release of the shoe cover 4. In order to facilitate the release of the shoe cover, the first hook 501 and the second hook 502 are designed with an arc, which is easy to release after being subjected to a downward force, and at the same time, the height direction stroke of the pedal 601 can be increased. Slide grooves are arranged on both sides of the pedal 601. The slide grooves can adopt I-shaped grooves or other restrictive grooves to restrict the slide plate 504 in the slide grooves and can move along the slide grooves. The other end of the pedal 601 is L-shaped. The spring is connected to one end of the slide plate 504 and the end of the L-shaped pedal 601. When the pedal 601 is stepped on, the pedal 601 moves down with the slide plate 504, and the vertical surfaces 508 of the first protrusion 505 and the second protrusion 506 are disengaged. The slide plate 504 rebounds under the action of the corresponding spring 7. After the pedal 601 is released, the slide plate 504 is reset, and the conveying device 3 conveys the next shoe cover 4 to the predetermined position, and the opening device 5 is actuated to open the next shoe cover 4 again.
