The symmetrical distribution of the entire part can ensure the integrity and firmness of the shoe cover structure. The distribution points of the traceless glue are as follows: Figure 5 shown.

[0037] It is mainly distributed on the outside of the paper shoe cover, and surrounds the main part of the shoe cover, and is symmetrically distributed about the central axis of the paper shoe cover. There are six points on each side of the main side, which can ensure the firmness of the adhesion and ensure that the shoe cover will not fall or compile during use, affecting the experience. At the same time, there are three points on the upper and lower parts of the paper shoe cover to ensure the overall connection of the paper shoe cover. At the same time, the distribution of the traceless glue points can be used to enhance the bearing capacity of the shoe cover.

[0038] Embodiment 2

[0039] In this embodiment, a shoe cover machine is disclosed. The shoe cover machine includes a shell, a paper storage unit, a transmission unit, and a shoe cover unit.

[0040] Specifically, Figure 1As shown, the housing structure in this embodiment includes a housing 1, a top cover 2, a hinge 3, a front cover 11 and a connecting rod 12. The top cover 2 is connected to the housing 1 through the hinge 3, and can be easily opened and closed, so that the paper shoe cover can be easily replaced. The front cover 11 plays a role in protecting the internal mechanism and aesthetically pleasing.

[0041] Among them, the shell 1, as the basic supporting structure of the entire shoe cover machine, provides installation space and protection for internal components. Two chambers are arranged in the shell 1, namely a first chamber 101 and a second chamber 102, and the two chambers are interconnected. The paper storage unit is located in the first chamber 101, the shoe cover unit is located in the second chamber 102, and the conveying unit is used to convey the paper shoe cover roll in the first chamber 101 to the second chamber 102.

[0042] The top cover 2 is tightly matched with the shell body 1, and the paper storage unit can be conveniently accessed through the top cover 2 so as to add or replace the paper shoe cover.

[0043] The hinge 3 is a key component connecting the housing 1 and the top cover 2, allowing the top cover 2 to be opened and closed freely within a certain angle range, which is convenient for user operation.

[0044] The front cover 11 is connected to the housing 1 to form a complete appearance while protecting the internal mechanism from dust and debris.

[0045] like Figure 2 and Figure 4 As shown, the paper storage unit in this embodiment includes a rotating shaft 4, a bearing 5, a bearing seat 6 and a fixing member 16. The paper shoe cover roll is sleeved on the rotating shaft 4, and both ends of the rotating shaft 4 are mounted on the bearing seat 6 through the bearing 5, so that the paper shoe cover can rotate smoothly. The fixing member 16 is used to fix the paper shoe cover roll to prevent it from moving.

[0046] Specifically, the rotating shaft 4, as a storage core of the paper shoe covers, allows the paper shoe covers to be neatly rolled thereon, facilitating continuous paper supply.

[0047] The bearing 5 is closely matched with the rotating shaft to ensure that the paper shoe cover can be unfolded smoothly.

[0048] The bearing seat 6 provides stable support for the bearing, ensuring that the overall structure of the paper storage unit is stable and reliable.

[0049] like Figure 2 and Figure 4 As shown, the transmission unit in this embodiment includes a transmission shaft 7, a rubber sleeve 8, a smooth flat plate 9, and a driving device 10 (including power components such as a motor). When the paper shoe cover is sent out from the paper storage unit, the transmission shaft 7 smoothly transmits the paper shoe cover to the smooth flat plate 9 through the rubber sleeve 8, ready for the next step of shoe cover operation. The driving device 10 provides power for the transmission shaft 7.

[0050] Specifically, the transmission shaft 7, as a core component for transmitting power, is responsible for transmitting power to the sleeve.

[0051] The sleeve 8 is tightly sleeved on the transmission shaft, driving the paper shoe cover to move forward steadily on the smooth flat plate.

[0052] The smooth plate 9 provides a smooth surface for the paper shoe cover to be conveyed.

[0053] The driving device 10 provides power to the conveying shaft to ensure that the paper shoe cover can accurately reach the overshoe unit.

[0054] like Figure 1 -As shown in the figure, the overshoe unit in this embodiment is the core part of the shoe cover machine, and its structure includes a vertically lifting pedal and a plurality of pressing plates distributed around the pedal, and the plurality of pressing plates are driven by an electric cylinder to flip toward the direction of the pedal;

[0055] Specifically, it is composed of a pedal 21, a spring 18, a limit block 19, a trigger button 20, a front block 13, a side block 23, a rear block 27 and a plurality of clamping devices (including a front clamping piece 22, a side front clamping piece 24, a side rear clamping piece 25, a rear clamping piece 26 and an electric cylinder 14, etc.). Each clamping piece is designed to conform to the shoe surface better, such as Figure 4 As shown in the figure, the opposite sides of the front and rear clamping plates are both arc-shaped, and the rear clamping plate 26 has a smaller arc that fits the heel of the shoe, while the front clamping plate 22 has a larger arc that fits the shoe upper. The clamping plates on the left and right sides adopt a slightly arc-shaped contour design to better fit the shoe upper.

[0056] When the user's foot steps on the pedal 21, the spring 18 is compressed, and the trigger button 20 starts the overshoe program. Subsequently, each pressing device, under the push of the electric cylinder 14, closely fits the paper shoe cover to the shoe surface.

[0057] Specifically, the pedal 21 is the part that the user steps on to start.

[0058] The blocks guide and position the paper shoe cover, and the side of each block facing the pedal 21 is arc-shaped, which is convenient for lifting the corresponding hinge.

[0059] The pressing device (front pressing piece 22, side front pressing piece 24, side rear pressing piece 25, rear pressing piece 26) ensures that the paper shoe cover fits the shoe tightly.

[0060] The electric cylinder 14 provides power for the pressing device.

[0061] The connecting shaft and the fixing member 15 ensure the effective transmission of power.

[0062] The guide rail platform 16 provides a stable running track for the electric cylinder.

[0063] At the same time, in this embodiment, the bottom of the pedal 21 is composed of six springs 18, five limit blocks 19 and a trigger button 20, and the trigger button 20 is slightly higher than the limit block 19. When the pedal 21 is subjected to pressure, the pedal 21 first contacts and hits the trigger button 20 to start the device, and then hits the limit block 19 to avoid excessive compression of the spring 18 and extend its service life. All extrusion devices are composed of a clamping plate, a connector, an electric cylinder, and a guide rail. The power element of all clamping devices is a LAF50-024D type micro-electric cylinder, which adopts an integrated drive and control design, small size, high precision, and high power density. In addition, the electric cylinder is equipped with a force sensor, which can realize automatic start and stop when the guide rod force is greater than the set value, and can realize the shoe cover to be pressed to the upper and then retreat, so that the paper shoe cover is more closely fitted to the upper. The rear side clamping device is the same as the rear clamping device connector, and is vertically connected to the clamping plate so that it can only move in a straight line. The front clamping device and the front side clamping device have the same connecting parts, which are horizontally connected to the clamping sheet and can make it rotate. The guide rail is connected to the electric cylinder for fixing. The clamping sheets of the front clamping device and the front side clamping device are rubber plates with a larger curvature. The clamping sheet of the rear side clamping device is a rectangular rubber flat plate. The clamping sheet of the rear clamping device is a U-shaped rubber block with a smaller curvature. The clamping sheet of rubber material is easy to deform and can better fit the shoe cover to the shoe surface. The six blocks are respectively connected to the connecting rod and are respectively located above the front clamping device, the two front side clamping devices, the two rear side clamping devices, and the rear clamping device.

[0064] The overshoe unit is provided with a sign to guide the user to step correctly.

[0065] 3. Workflow

[0066] When the preparation is complete, the user places his foot on the paper shoe cover and steps on the pedal 21. At this time, the spring 18 is compressed, and the pedal 21 moves down together with the paper shoe cover. Since the paper shoe cover is already in a tensioned state and there are perforated lines 31 between adjacent paper shoe covers, the paper shoe cover can be easily separated from the paper shoe cover roll. Then, each pressing device will be started in turn, and the pressing sheet will fit the shoe surface under the push of the electric cylinder 14 to ensure that the paper shoe cover tightly wraps the shoe surface. When all the pressing devices have completed their work, the shoe cover machine will automatically stop running, and the shoe cover has been perfectly fitted on the shoe surface.

[0067] The specific working principle is as follows:

[0068] S1 Preparation: Open the top cover 2, rotate it 90 degrees clockwise around the hinge 3, separate it from the shell 1, and expose the paper storage unit. Disassemble the rotating shaft 4 and the bearing 5 of the paper storage unit, and wrap the paper shoe roll on the rotating shaft 4 to complete paper storage. The rotating shaft 4 is connected to the bearing 5 and can rotate freely, so that paper can be discharged freely. When the paper storage unit is finished storing paper, remove the front end of the paper shoe roll and place it at the junction of the two sleeves 8.

[0069] S2 The shoe cover machine is turned on, the drive motor 10 is started, the transmission shaft 7 rotates to drive the sleeve 8 to engage and rotate, thereby driving the paper shoe cover to move forward on the smooth flat plate 9. The paper shoe cover can move toward the shoe cover unit in multiple directions. In this embodiment, the paper shoe cover moves toward the shoe cover unit along its wider side. When the fold of one side of the paper shoe cover passes through the side block 23, it will flip due to the effect of the fold, and the flip angle is less than the height of the side block 23, so that when the fold moves to the other side block 23, it can move upward under the guidance of the side block 23. At the same time, when the side fold reaches the other side block 23, the paper shoe cover is just above the pedal 21. At this time, the drive motor 10 stops driving, the rotating shaft 7 and the sleeve 8 stop rotating, and the paper shoe cover is tightly squeezed to stop moving, and the paper shoe cover is tensioned. At the same time, since there is no support in the middle part of the paper shoe cover, it will sink under the action of gravity and the fold, which is convenient for users to step on.

[0070] S3 Overshoe operation: The user steps on the paper shoe cover of the overshoe structure in a certain direction according to the guidance, and then steps on the pedal 21. The spring 18 is compressed by pressure, and the pedal 21 moves down together with the paper shoe cover. Since the paper shoe cover is originally in a tensioned state and there are perforated lines between adjacent paper shoe covers, the paper shoe covers are separated from the paper shoe cover roll.

[0071] S31 At the same time, the pedal 21 moves downward to press the trigger button 20, starting the clamping device, and the pedal 21 stops moving under the limit of the limit block 19;

[0072] After the trigger button 20 is activated at step S32, the front pressing device is activated first, the push rod of the electric cylinder 14 moves forward linearly, and the front pressing sheet 22 is attached to the front shoe surface under the action of the electric cylinder 14;

[0073] S33 Then the two side front pressing plates 24 on the left and right sides drive the paper shoe covers at the corresponding positions to fit onto the inclined surface in turn under the driving of the pressing device;

[0074] S34 again, the two side rear pressing plates 25 on the left and right sides are driven by the pressing device to drive the paper shoe covers at the corresponding positions to fit onto the inclined surface in turn;

[0075] S35 Finally, the rear pressing sheet 26 drives the paper shoe cover at the corresponding position to fit onto the inclined surface under the driving of the pressing device;

[0076] S36 completes the overshoeing process, and after the paper shoe covers at all parts are completely fitted to the shoe upper, the force sensor on the electric cylinder 14 detects that the pressure on the push rod is too large, and the push rod stops moving forward and retreats, so that the front clamping device returns to its original position.

[0077] Compared with the prior art, the utility model has the following advantages: most traditional shoe cover machines use plastic as raw material to make shoe covers, while the utility model innovatively uses paper materials as raw materials to make shoe covers, the material cost is low, and it has a positive effect on environmental protection; the paper shoe covers used in the utility model are specially customized, so that the material specifications are unified; the utility model also innovates in the way of covering shoes, the paper shoe covers can completely wrap the upper, but will not directly adhere to the upper, which is convenient for the separation of the shoe covers from the upper; in addition, the utility model is innovative in structure, the shoe cover machine as a whole includes a shoe covering unit and a paper transfer unit, and the corresponding pressing device is designed according to the characteristics of different surfaces of the upper to ensure the good fitting effect of the shoe cover, so that the structure is more perfect and the reliability is higher. In addition, the pressing device has most of the same parts and can be used interchangeably, which is convenient for maintenance and large-scale production.
