Description

Technical Field

[0001] This invention relates to the field of shoe washing equipment technology, and in particular to a shoe washing machine. Background Technology

[0002] As is well known, as shown in the attached document Figures 15-17 As shown, shoes generally include the upper, tongue, and sole. The upper is divided into the forefoot, heel, left side, right side, and crown according to its position.

[0003] Shoe washing machines are devices that replace manual shoe washing, greatly simplifying people's daily lives. Existing shoe washing machines mainly use clamps or other grippers to hold the shoes in place, then drive brushes to actively clean them, or drive the clamps to passively brush the shoes onto the brushes, thus completing the cleaning process. However, the clamps hold the shoes to the outer surface, preventing those areas from being cleaned properly, resulting in incomplete cleaning. Alternatively, the clamping points may need to be constantly changed for repeated brushing, leading to low cleaning efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a shoe washing machine that solves the problem that the outer surface of the shoe cannot be cleaned properly when the shoe is clamped during the washing process.

[0005] The technical solution adopted by this invention to solve its technical problem is: a shoe washing machine, comprising:

[0006] frame;

[0007] A scrubbing device is located below the frame;

[0008] Several shoe stretching devices are located above the washing device. The shoe stretching device includes a vertical pole, a rear support, and a front support, as well as a stretching drive mechanism that drives the front support and the rear support to move away from or towards each other. The front support and the rear support are disposed at one end of the vertical pole, and the front support is movably connected to the rear support through a first sliding mechanism. The vertical pole is movably disposed on the frame through a moving device.

[0009] As a further embodiment, the tensioning drive mechanism includes a push rod, a linear bearing movably mounted on the upright, and a tensioning drive member that drives the linear bearing to move along the upright. The rear support is fixed to one end of the upright, one end of the push rod is hinged to the front support, the other end of the push rod is hinged to the linear bearing, and the tensioning drive member is mounted on the upright.

[0010] As a further embodiment, the first sliding mechanism includes a slider and a slide rail. The slider is fixed on the rear support, one end of the slide rail is fixedly connected to the front support, and the other end of the slide rail is slidably engaged with the slider. An avoidance channel for cooperating with the slide rail is provided in the rear support.

[0011] As a further embodiment, pulleys are installed on the front support and / or rear support, with the pulleys located on the side of the front support and / or rear support away from the upright.

[0012] As a further embodiment, the shoe tensioning device also includes a shoe tongue pressing mechanism, which includes a connecting block, a pressing band, and a pressing drive that drives the connecting block to move along the axis of the upright. One end of the pressing band is fixed to the front support, and the other end of the pressing band is fixed to the connecting block. The pressing drive is mounted on the upright.

[0013] As a further embodiment, the upright has a liquid inlet channel extending through both ends, the rear support has a liquid storage chamber inside, and the surface of the rear support has multiple spray holes. The liquid inlet channel is connected to the liquid storage chamber, and the spray holes are connected to the liquid storage chamber.

[0014] As a further embodiment, the moving device includes a lifting mechanism, a tilting mechanism, and a horizontal moving mechanism. The upright is driven to the output end of the lifting mechanism, the lifting mechanism is driven to the output end of the tilting mechanism, the tilting mechanism is driven to the output end of the horizontal moving mechanism, and the horizontal moving mechanism is mounted on the frame.

[0015] As a further embodiment, the lifting mechanism includes a fixed plate, a lifting drive component, a lead screw, and a first mounting plate. The lead screw is mounted on the fixed plate, the lifting drive component is fixed on the fixed plate and located on one side of the lead screw, and the output end of the lifting drive component is connected to one end of the lead screw via a first synchronous pulley and a first synchronous belt. The end of the upright pole away from the rear support is fixed on the first mounting plate. The first mounting plate is movably connected to the fixed plate via a second sliding mechanism, and one side of the first mounting plate is provided with a pull block. The pull block passes through the fixed plate and is connected to the lead screw via a lead screw nut. The fixed plate is connected to the output end of the tilting mechanism.

[0016] As a further embodiment, the flipping mechanism includes a flipping drive and a reducer installed at the output end of the flipping drive. Both ends of the fixed plate are mounted on the frame via bearing seats, and one end of the fixed plate is drivenly connected to the output end of the reducer. The bearing seat is drivenly connected to the output end of the horizontal moving mechanism.

[0017] The horizontal moving mechanism includes a transmission rod and a horizontal moving drive component. The horizontal moving drive component is connected to the middle part of the transmission rod. Both ends of the transmission rod are mounted on the frame via a second synchronous pulley and a second synchronous belt. Both bearing seats are movably connected to the frame via a third sliding mechanism, and the two bearing seats are respectively fixed on the two second synchronous belts.

[0018] As a further embodiment, the scrubbing device includes an open water tank and a first brush. The water tank is provided with several cleaning tanks. The first brush is fixed to the tank wall and the bottom of the cleaning tank, and a cleaning channel is formed between the first brush on the tank wall and the bottom of the cleaning tank.

[0019] The scrubbing device further includes a plurality of second brushes and a second brush moving mechanism. The second brush moving mechanism includes a second mounting plate, a third mounting plate, a first driving member for driving the second mounting plate to move horizontally, and a second driving member for driving the third mounting plate to move up and down. The second brushes are fixed on the third mounting plate and are located above the cleaning channel. The second driving member is mounted on the second mounting plate, and the second mounting plate is movably connected to the frame through a fourth sliding mechanism. The first driving member is mounted on the frame.

[0020] The beneficial effects of this invention are as follows: The front support is movably connected to the rear support via a first sliding mechanism. This first sliding mechanism maintains a movable connection between the front and rear supports. A tensioning drive mechanism moves them apart or closer together, allowing the overall size of the two supports to vary, facilitating the slipping on of shoes. The front support is tensioned from the inside of the shoe at the forefoot, and the rear support is tensioned from the inside of the shoe at the heel. This, combined with the front and rear supports, secures the shoe from the inside, preventing it from easily falling off. The front and rear supports are located at one end of a vertical pole, which is movably mounted on a frame via a moving device. This moving device moves the vertical pole, thereby moving the tensioned shoe to a washing device. The washing device washes the outer surface of the shoe, and since the front and rear supports do not occupy the outer surface, the shoe's outer surface can be thoroughly cleaned.

[0044] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," "third," "fourth," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] As attached Figures 1-2 As shown in Figures 5 and 6, the shoe washing machine provided in this embodiment includes a frame 1, a brushing device 2, and several shoe stretching devices 3.

[0047] As attachedFigures 1-2 As shown, frame 1 serves as the framework of the shoe washing machine, providing stability and support.

[0048] As attached Figure 1 , 4 As shown, the brushing device 2 is located below the frame 1, and the brushing device 2 is used to brush the outer surface of the shoe 5.

[0049] As attached Figure 1 , 7 As shown, several shoe tensioning devices 3 are located above the washing device 2. Each shoe tensioning device 3 includes a vertical pole 31, a rear support 32, and a front support 33, as well as a tensioning drive mechanism 34 that drives the front support 33 and the rear support 32 to move away from or towards each other. Specifically, when the front support 33 and the rear support 32 are close to each other, the overall size formed between them is relatively short, making it easy to slip the shoe 5 onto the front support 33 and the rear support 32 through the shoe opening 58. At this time, the front support 33 and the rear support 32 enter the shoe. Then, the tensioning drive mechanism 34 drives the front support 33 and the rear support 32 to move away from each other, resulting in a longer overall size between them, which is longer than the size of the shoe opening 58. The front support 33 is tensioned from inside the shoe 5 to the forefoot 51, and the rear support 32 is tensioned from inside the shoe 5 to the heel 52. Thus, the shoe 5 is tensioned and fixed from inside the shoe 5 through the front support 33 and the rear support 32, and the shoe 5 is not easy to fall off. The front support 33 and the rear support 32 are located at one end of the upright 31. The front support 33 is movably connected to the rear support 32 via a first sliding mechanism 344. The first sliding mechanism 344 keeps the front support 33 and the rear support 32 movably connected. The tensioning drive mechanism 34 drives them to move away from each other or closer to each other, so that the overall size of the two can be changed, which is convenient for putting on the shoe 5 and tightening the shoe 5 from the inside. The upright 31 is movably mounted on the frame 1 via a moving device 4. The moving device 4 can drive the upright 31 to move, thereby driving the front support 33 and the rear support 32 to move the tightened shoe 5 to the washing device 2. The washing device 2 washes the outer surface of the shoe 5, and the front support 33 and the rear support 32 do not occupy the outer surface of the shoe 5, so that the outer surface of the shoe 5 can be cleaned.

[0050] In this embodiment, the front support 33 is movably connected to the rear support 32 via a first sliding mechanism 344. The first sliding mechanism 344 keeps the front support 33 and the rear support 32 movably connected. The tensioning drive mechanism 34 drives the two supports to move away from each other or closer together, thereby allowing the overall size of the two supports to change, making it easier to put on the shoe 5. The front support 33 is tensioned from inside the shoe 5 to the forefoot 51, and the rear support 32 is tensioned from inside the shoe 5 to the heel 52. Thus, the front support 33 and the rear support 32 tension and fix the shoe 5 from inside the shoe 5, making it less likely for the shoe 5 to fall off. The front support 33 and the rear support 32 are set at one end of the upright 31. The upright 31 is movably mounted on the frame 1 through the moving device 4. The moving device 4 can drive the upright 31 to move, thereby driving the front support 33 and the rear support 32 to move the stretched shoe 5 to the brushing device 2. The brushing device 2 brushes the outer surface of the shoe 5, while the front support 33 and the rear support 32 do not occupy the outer surface of the shoe 5, so that the outer surface of the shoe 5 can be cleaned.

[0051] The above-described solutions, as feasible embodiments, are shown in the appendix. Figure 7 As shown, the tensioning drive mechanism 34 includes a push rod 341, a linear bearing 342 movably mounted on the upright 31, and a tensioning drive member 343 that drives the linear bearing 342 to move along the upright 31. The rear support 32 is fixed to one end of the upright 31, maintaining a relatively fixed position relative to the upright 31. This ensures that the front support 33 remains relatively stable as it moves away from or closer to the rear support 32, thus better tensioning the shoe 5 from within. One end of the push rod 341 is hinged to the front support 33, and the other end is hinged to the linear bearing 342. The tensioning drive member 343 is mounted on the upright 31. Specifically, the tensioning drive 343 can be a cylinder. The output end of the tensioning drive 343 is connected to the linear bearing 342. The cylinder drives the linear bearing 342 to move along the upright 31 and closer to the rear support 32, thereby causing the push rod 341 to push the front support 33 away from the rear support 32. The overall size formed by the front support 33 and the rear support 32 increases, thus tightening the shoe 5. The cylinder resets, causing the linear bearing 342 to move along the upright 31 and away from the rear support 32, thereby causing the push rod 341 to pull the front support 33, bringing it closer to the rear support 32. The overall size formed by the front support 33 and the rear support 32 decreases, thus loosening the shoe 5. The overall size formed by the front support 33 and the rear support 32 is then detached from the shoe opening 58, making it easy to remove the shoe 5 and replace it with a shoe that needs to be washed. The tensioning drive 343 can also be other designs, as long as it allows the linear bearing 342 to move along the upright 31.

[0052] It is worth noting that the tensioning drive mechanism 34 can also be other options, as long as it can drive the front support 33 and the rear support 32 to move away from or towards each other.

[0053] Additionally, as attachedFigure 12 As shown, the first sliding mechanism 344 includes a slider 3441 and a slide rail 3442. The slider 3441 is fixed to the rear support 32. One end of the slide rail 3442 is fixedly connected to the front support 33, and the other end of the slide rail 3442 is slidably engaged with the slider 3441, thereby allowing the front support 33 and the rear support 32 to be movably connected, and the front support 33 and the rear support 32 to move closer to or further away from each other. It is worth noting that the rear support 32 has a clearance channel 3443 that cooperates with the slide rail 3442. Thus, during the process of the front support 33 and the rear support 32 moving closer to or further away from each other, the slide rail 3442 moves within the clearance channel 3443, and the slide rail 3442 will not interfere with the effect of tightening the shoe 5 due to being exposed on the surface of the rear support 32.

[0054] Alternatively, the first sliding mechanism 344 can also be selected from other options, as long as it allows the front support 33 and the rear support 32 to be movably connected, and the front support 33 and the rear support 32 to move closer to each other or further away from each other.

[0055] Based on the solution in this embodiment, as shown in the appendix Figure 12 As shown, pulleys 35 are installed on the front support 33 and / or the rear support 32. The pulleys 35 are located on the side of the front support 33 and / or the rear support 32 away from the upright 31. This allows the front support 33 and / or the rear support 32 to slide against the insole of the shoe 5 as they move closer or further apart, reducing friction and preventing the front support 33 and / or the rear support 32 from getting stuck on the insole of the shoe 5. Furthermore, during the process of putting on the shoe 5, the pulleys 35 slide against the shoe opening 58, which facilitates putting on the shoe 5 and prevents the front support 33 and / or the rear support 32 from getting stuck at the shoe opening 58.

[0056] Based on the solution in this embodiment, as shown in the appendix Figure 7As shown, the shoe tensioning device 3 also includes a tongue clamping mechanism 36. The tongue clamping mechanism 36 includes a connecting block 361, a clamping band 362, and a clamping drive member 363 that drives the connecting block 361 to move along the axis of the upright 31. One end of the clamping band 362 is fixed to the front support 33, and the other end of the clamping band 362 is fixed to the connecting block 361. The clamping drive member 363 is mounted on the upright 31. After the shoe 5 is fitted onto the front support 33 and the rear support 32, the tensioning drive mechanism 34 is activated, causing the front support 33 to clamp from inside the shoe 5 to the front vamp 51, and the rear support 32 to clamp from inside the shoe 5 to the rear vamp 52. The clamping drive 363 can be a cylinder. The clamping drive 363 drives the connecting block 361 away from the rear support 32, which in turn pulls the clamping band 362. The clamping band 362 can be an elastic band. The clamping band 362 deforms and presses against the shoe tongue 56, thus pressing the shoe tongue 56 against the shoe top 55 from the inside of the shoe. This provides three points of force for fixing the shoe 5, tightening it from the inside. The clamping drive 363 can also be other designs, as long as it allows the connecting block 361 to move along the axis of the upright 31.

[0057] Alternatively, the tongue pressing mechanism 36 can also be other options, as long as it can press the tongue 56 firmly against the top of the shoe 55.

[0058] In the above scheme, as shown in the appendix Figures 5-7 As shown, when the shoe opening 58 of the shoe 5 is placed upwards on the front support 33 and the rear support 32, the shoe tongue 56 will block the shoe opening 58 due to its own weight, making it difficult to put on the shoe 5. Therefore, in this embodiment, the shoe opening 58 of the shoe 5 is placed downwards. At this time, the shoe tongue 56 descends under its own weight and moves away from the shoe opening 58, making it easier to put the shoe 5 on the front support 33 and the rear support 32 through the shoe opening 58. It also helps the clamping strap 362 to press the shoe tongue 56 tightly against the top of the shoe 55 from the inside of the shoe.

[0059] In the feasible solutions of this embodiment, as shown in the appendix Figures 8-14 As shown, the upright 31 has a liquid inlet channel 311 extending through both ends, which is used to connect to a pumping device that provides cleaning fluid via a pipe. The rear support 32 has a liquid storage chamber 321 inside, and multiple spray holes 322 are formed on the surface of the rear support 32. The liquid inlet channel 311 communicates with the liquid storage chamber 321, and the spray holes 322 communicate with the liquid storage chamber 321.

[0060] The pumping device pumps the cleaning solution into the inlet channel 311 through a pipeline, which then flows into the storage chamber 321. The storage chamber 321 acts as a buffer for saturation before the solution is sprayed out through the spray nozzle 322, thus cleaning the inside of the shoe 5. It should be noted that by increasing the pumping pressure of the cleaning solution, the flow rate of the cleaning solution sprayed from the spray nozzle 322 is increased. The higher flow rate of the cleaning solution allows for more effective cleaning of dirt inside the shoe 5. It is worth mentioning that, in the aforementioned solution, a pulley 35 is installed on the front support 33 and / or the rear support 32. The pulley 35 is located on the side of the front support 33 and / or the rear support 32 away from the upright 31. By setting the pulley 35, there is a space between the side of the front support 33 and / or the rear support 32 away from the upright 31 and the insole of the shoe 5. This allows the cleaning fluid to be sprayed out from the spray hole 322 on the surface of the rear support 32, avoiding the situation where the insole of the shoe 5 blocks the spray hole 322, preventing the cleaning fluid from being unable to spray out and thus failing to clean the insole of the shoe 5, or the situation where the spraying range is too small and the cleaning is not thorough.

[0061] The above-described solutions, as feasible embodiments, are shown in the appendix. Figures 1-2 As shown in Figures 5-6, the moving device 4 includes a lifting mechanism 41, a flipping mechanism 42, and a horizontal moving mechanism 43. The upright 31 is driven to the output end of the lifting mechanism 41. The lifting mechanism 41 drives the shoe 5 to be raised and lowered, allowing the shoe 5 to descend into the washing device 2 for washing. The lifting mechanism 41 is driven to the output end of the flipping mechanism 42. The flipping mechanism 42 drives the front support 33 and the rear support 32 to be flipped above the frame 1, facilitating the placement of the shoe 5 with its opening 58 facing down onto the front support 33 and the rear support 32. The flipping mechanism 42 is driven to the output end of the horizontal moving mechanism 43. The horizontal moving mechanism 43 is mounted on the frame 1. The horizontal moving mechanism 43 drives the shoe 5 to move horizontally within the washing device 2 for washing.

[0062] Among them, as attached Figures 5-6As shown, the lifting mechanism 41 includes a fixed plate 412, a lifting drive component 413, a lead screw 414, and a first mounting plate 415. The lead screw 414 is mounted on the fixed plate 412. The lifting drive component 413 is fixed on the fixed plate 412 and located on one side of the lead screw 414. The output end of the lifting drive component 413 is connected to one end of the lead screw 414 via a first synchronous pulley 416 and a first synchronous belt 417. The end of the upright 31 away from the rear support 32 is fixed on the first mounting plate 415. The first mounting plate 415 is movably connected to the fixed plate 412 via a second sliding mechanism. A pull block 418 is provided on one side of the first mounting plate 415. The pull block 418 passes through the fixed plate 412 and is connected to the lead screw 414 via a lead screw nut 419. The fixed plate 412 is connected to the output end of the flipping mechanism 42. The lifting drive component 413 is a servo motor. It drives the first synchronous pulley 416 and the first synchronous belt 417, thereby rotating the lead screw 414. This, in turn, causes the first mounting plate 415 and the upright post 31 to rise and fall relative to the fixed plate 412, thus raising and lowering the shoe 5. The second sliding mechanism includes a slide rail and a slider. The slide rail and slider slide in a sliding engagement, which is a conventional technique and will not be described in detail.

[0063] The lifting mechanism 41 can also be other options, as long as it can make the pole 31 rise and fall.

[0064] The above-described solutions, as feasible embodiments, are shown in the appendix. Figure 2 As shown, the flipping mechanism 42 includes a flipping drive 421 and a reducer 422 mounted on the output end of the flipping drive 421. Both ends of the fixed plate 412 are mounted on the frame 1 via bearing seats 423, allowing the fixed plate 412 to rotate relative to the frame 1. One end of the fixed plate 412 is connected to the output end of the reducer 422, and the bearing seat 423 is connected to the output end of the horizontal moving mechanism 43. The flipping drive 421 is a servo motor, which drives the fixed plate 412 to flip, thereby causing the shoe 5 to flip.

[0065] The flipping mechanism 42 can also be other options, as long as it can make the fixed plate 412 flip.

[0066] The above-described solutions, as feasible embodiments, are shown in the appendix. Figure 1As shown, the horizontal movement mechanism 43 includes a transmission rod 431 and a horizontal movement drive component 432. The horizontal movement drive component 432 is connected to the middle of the transmission rod 431. Both ends of the transmission rod 431 are mounted on the frame 1 via second synchronous pulleys 433 and second synchronous belts 434. Both bearing seats 423 are movably connected to the frame 1 via a third sliding mechanism, and the two bearing seats 423 are respectively fixed on the two second synchronous belts 434. The horizontal movement drive component 432 uses a servo motor paired with a coupling to drive the transmission rod 431 to rotate, which in turn drives the second synchronous pulleys 433 and the second synchronous belts 434 to rotate, causing the two bearing seats 423 to move horizontally on the frame 1, thereby driving the shoe 5 to move horizontally. The third sliding mechanism includes a slide rail and a slider, which slide in a conventional manner, so it will not be described in detail.

[0067] The horizontal moving mechanism 43 can also be other options, as long as it enables the bearing housing 423 to move horizontally.

[0068] The above-described solutions, as feasible embodiments, are shown in the appendix. Figure 4 As shown, the washing device 2 includes an open water tank 21 and a first brush 22. The water tank 21 is provided with several cleaning tanks 211. The first brush 22 is fixed to the tank wall and bottom of the cleaning tank 211, and a cleaning channel 212 is formed between the first brush 22 on the tank wall and bottom of the cleaning tank 211. The cleaning tank 211 is filled with cleaning fluid. Initially, the front support 33 and the rear support 32 of the shoe tensioning device 3 face upward and are located above the frame 1. Then, the shoe opening 58 of the shoe 5 is placed downward and the shoe 5 is put on the front support 33 and the rear support 32 through the shoe opening 58. After the front support 33 and the rear support 32 are tensioned by the tensioning drive mechanism 34, the flipping mechanism 42 drives the shoe 5 to flip so that the shoe opening 58 of the shoe 5 faces upward. The lifting mechanism 41 drives the upright 31 to lower the shoe 5 into the cleaning channel 212 of the cleaning tank 211. The horizontal moving mechanism 43 drives and moves the shoe 5 back and forth horizontally in the cleaning channel 212, so that the first brush 22 in the cleaning tank 211 brushes the sole 57, forefoot 51, heel 52, left side 53, and right side 54 of the shoe 5, thereby cleaning the outer surface of the shoe 5.

[0069] It is worth mentioning that the water tank 21 has an even number of cleaning tanks 211. When there are two cleaning tanks 211, the two cleaning tanks 211 are connected and clean the same pair of shoes 5 respectively. When there are four or more cleaning tanks 211, they are used to clean different pairs of shoes 5. Therefore, the cleaning tanks 211 for different pairs of shoes 5 are separated by partitions to avoid contamination of the cleaning solution and resulting in unsanitary conditions.

[0070] Due to the irregular curved surface design of the forefoot 51 and the top 55, the first brush 22 is difficult to clean. Therefore, in some embodiments, as shown in the attached... Figures 2-4As shown, the scrubbing device 2 also includes several second brushes 23 and a second brush moving mechanism 24. The second brush moving mechanism 24 includes a second mounting plate 241, a third mounting plate 242, a first driving member 243 for horizontal movement of the second mounting plate 241, and a second driving member 244 for lifting and lowering the third mounting plate 242. The second brushes 23 are fixed to the third mounting plate 242 and are located above the cleaning channel 212. The second driving member 244 is mounted on the second mounting plate 241, and the second mounting plate 241 is movably connected to the frame 1 via a fourth sliding mechanism. The first driving member 243 is mounted on the frame 1. The first driving member 243 can be a cylinder, which drives the second mounting plate 241 to move horizontally. The second driving member 244 can be a cylinder, which drives the third mounting plate 242 to lift and lower. Before the flipping mechanism 42 flips the shoe 5, the first drive member 243 drives the second mounting plate 241 to move horizontally, thereby moving the third mounting plate 242 and the second brush 23 to one side of the water tank 21, thus not interfering with the flipping mechanism 42 flipping the shoe 5. After the shoe 5 is flipped and adjusted to a suitable tilt angle by the flipping mechanism 42, the first drive member 243 drives the third mounting plate 242 and the second brush 23 to move above the cleaning channel 212 of the water tank 21. The second drive member 244 drives the second brush 23 to descend to the top 55 or the forefoot 51 of the shoe 5. Then, the horizontal movement mechanism 43 drives and moves the shoe 5 back and forth horizontally, so that the second brush 23 brushes the top 55 or the forefoot 51 of the shoe 5, ensuring that the shoe 5 is clean. The fourth sliding mechanism includes a slide rail and a slider, which slide together. This is a conventional technology and will not be described in detail.

[0071] It is worth mentioning that, as described above, fitting the shoe 5 onto the front support 33 and the rear support 32 can be done by a robotic arm or manually.

[0072] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
