Description

Technical Field

[0001] This application relates to the field of equipment cleaning technology, specifically to an automatic cleaning device. Background Technology

[0002] Board games are traditional Chinese recreational tools, including mahjong, Chinese chess, Go, and military chess. After use, a set of mahjong tiles or chess pieces accumulates a lot of stains, sweat, dust, and bacteria, requiring cleaning after each game. Existing cleaning methods include: The first is manual cleaning, where the tiles are placed face up, sprayed with cleaning agent, and then wiped individually. After cleaning one side, the tiles are flipped over to clean the second side – a time-consuming and laborious process with low efficiency. The second method uses automated cleaning machines. These machines typically have vertically arranged or drum-like cleaning systems similar to washing machines, performing wet washing, but this doesn't achieve a very thorough clean and only cleans a limited variety of items. Therefore, to avoid the shortcomings of existing technologies, it is necessary to improve them. Summary of the Invention

Detailed Implementation

[0045] Example 1

[0046] like Figures 1-14 The shuffling machine in this embodiment consists of two parts: a main body and a door, with various configuration devices installed inside the door.

[0047] The main body includes a main shell and a main frame. The main shell is wrapped around the main frame and specifically includes: the main front frame, the main upper front frame, the main middle frame, the main rear plate, and the main bottom plate.

[0048] The main body has several ventilation holes on the back panel, four casters at the four corners of the main body base plate, and a main body handle on the upper part of each side of the main body frame for easy movement of the cleaning machine by gripping the main body handle with both hands; the main body has a door in the center of the front frame, and a flip-up door panel corresponding to the drawer is located at the bottom of the door panel. A door handle is located on the outside of the flip-up door panel for opening and closing the flip-up door panel.

[0049] The main body's front upper frame houses a PCB control board, with a centrally located control panel housing. The control panel housing is covered by a control panel lens, with the inner side of the lens corresponding to the control buttons on the PCB control board. Externally, touch buttons are labeled with different commands, allowing control of the shuffling machine. These touch buttons include: power on / off, run / pause, fast wash (white light), fine wash (white light), and self-cleaning. Control of the shuffling machine is achieved through programming corresponding commands on the PCB control board. The main frame is located near the rear panel, with a drawer at the bottom and a motor module on one side of the drawer. The main frame is used to secure the roller assembly, hence the presence of tripod structures on both sides to prevent forward tilting. The roller assembly is connected to the motor module via belt drive, providing rotational power.

[0050] The specific structure of the roller device includes: a roller bearing support plate fixed on the main frame; a roller bearing fixing component fixedly installed on the roller bearing support plate; two sets of first bearings are sleeved inside the roller bearing fixing component; the roller rotating shaft is inserted into the two sets of first bearings; and they are assembled together on the outside by bearing pressure components; a roller pulley is fixed at the rear end of the roller rotating shaft; a roller base and a nylon bristle brush roller are fixed at the front end of the roller rotating shaft; the roller includes an inner roller shell and an outer roller shell; the inner roller shell and the outer roller shell are fixed together on the roller base; during assembly, the inner roller shell and the outer roller shell are installed first, and then the nylon bristle brush roller is installed.

[0051] The outer shell of the roller in this application is made of PC material (polycarbonate) or similar material using a vacuum forming process, and the inner layer of the roller is made of OPE material (oxidized polyethylene wax) or similar material using a high-temperature molding process. This greatly reduces the noise during the roller shuffling process. In addition, we also fix a layer of cotton cloth inside the inner shell of the roller or cover the inner wall of the roller with nylon filaments, which not only reduces noise but also prevents the mahjong tiles from scratching the mahjong tiles by contacting the inner wall of the roller during the shuffling process. The material of the nylon filament brush roller is also more suitable for cleaning mahjong tiles than other brushes and will not scratch the mahjong tiles.

[0052] The inner and outer shells of the roller are fixed to the roller chassis by bolts through holes in corresponding positions on both the inner and outer rings for secure tightening. Two ventilation holes in the middle ring facilitate moisture removal. Both the inner and outer shells have three sets of evenly distributed first arc-shaped protrusions. Between every two sets of first arc-shaped protrusions, two sets of second arc-shaped protrusions are evenly distributed. These arc-shaped protrusions facilitate the rotation of the cards as the roller rotates, allowing the cards to more easily and irregularly rotate within the roller, thus contacting the nylon bristle brush rollers for thorough cleaning.

[0053] A transmission assembly is provided between the motor module and the roller assembly in this application. Power is transmitted through a transmission wheel and belt drive. Since high speed is not required when cleaning a mahjong machine, the high speed output of the motor needs to be converted into a slow speed suitable for the mahjong cleaning machine. The transmission assembly of this application includes a double-layer pulley and a transmission bearing assembly. The transmission bearing assembly includes a transmission bearing support plate fixed to the main frame. A transmission bearing fixing component is fixed on the transmission bearing support plate. Two sets of second bearings are sleeved inside the transmission bearing fixing component. Adaptive rotating connecting pins are inserted into the two sets of second bearings. The rear end of the rotating connecting pin... A fixed double-layer pulley is connected to the roller pulley via a second belt drive. The front end of the transmission bearing fixing component has a transmission anti-rotation disc, and both have corresponding first bolt holes. A transmission bearing support plate is sandwiched between them and fixed to the transmission bearing support plate. The transmission bearing support plate has second bolt holes corresponding to the first bolt holes, and the diameter of the second bolt holes is larger than that of the first bolt holes. Anti-rotation pin locking components are located on adjacent sides of the transmission bearing support plate. By using anti-rotation screws to pull the bolts passing through the transmission bearing fixing component and the transmission anti-rotation disc, the position of the double-layer pulley can be finely adjusted, thereby adjusting the belt tension. This design facilitates, firstly, adjusting the pulley tension after installation and secondly, allowing for appropriate tightening in case of belt slippage, and making future maintenance and repairs more convenient.

[0054] The rear end of the motor module is equipped with a motor pulley. The motor pulley and the double-layer pulley are connected by a first belt drive. In this application, based on the motor output power and the drum size, the speed ratio between the motor pulley and the double-layer pulley is 6:1, and the speed ratio between the double-layer pulley and the drum pulley is also 6:1. Through speed conversion, the motor power does not need to be very high to drive the drum rotation, thus saving energy.

[0055] The door structure is a very important part of this application, including: a door upper shell, which is a frame structure, with a door viewing window lens at the front of the door upper shell, a cleaning fluid box, a water pump with a nozzle, a hot air module and a lighting panel in the middle, and a door back panel and an inner door viewing window lens at the back.

[0056] The inner viewing window is located on the upper part of the door back panel. The inner viewing window has a window of the same size as the inner viewing window and is used to observe the cleaning process inside the shuffling machine drum.

[0057] A cleaning fluid observation window is provided on the door viewing window lens, corresponding to the cleaning fluid tank, for observing the remaining cleaning fluid level. One end of the water pump, including the nozzle, is connected to the bottom of the cleaning fluid tank, while the other end has a nozzle at the top of the tank. A nozzle hole is located on the corresponding position on the door back panel. A light hole is provided on the door back panel corresponding to the lighting panel. The air outlet of the hot air module is located on the corresponding position on the door back panel. The hot air module provides hot air to dry the sign, while the water pump sprays cleaning fluid onto the sign for dry cleaning. Compared to wet cleaning, this method is more thorough and efficient.

[0058] One side of the upper shell of the door is movably connected to the front frame of the main body via a door hinge, and the other end is equipped with a door latch for opening and closing the door. The door of this application is circular, and its size is designed to be the same as or close to the diameter of the inner shell of the drum, making it convenient to open the door to retrieve or place the cleaned cards. The door can also be designed as a square or cuboid, but it must be larger than the end face of the inner shell of the drum for easy card retrieval and placement. A Hall effect sensor magnet is provided on the front frame of the main body, and a Hall effect board is provided at a corresponding position on the upper shell of the door. The Hall effect board is connected to the PCB control board. Through program settings, when the door is not sensed to be closed, the card shuffling machine does not work; when the door is suddenly closed, the card shuffling machine stops working, thereby improving the safety of equipment use.

[0059] The hot air module, water pump, lighting board, and motor module are connected to the PCB control board.

[0060] Usage: Open the door of the mahjong tiles to be cleaned and place them inside the drum. The ratio of the outer diameter of the nylon bristle brush roller to the inner diameter of the drum can be designed, for example, 2:3. Combined with different rotation speeds, different ratios of the outer diameter of the nylon bristle brush roller to the inner diameter of the drum, along with appropriate rotation speeds, can drive the mahjong tiles to be evenly distributed inside the drum, allowing the mahjong tiles to make full contact with the nylon bristle brush roller and the inner wall of the drum. Test the cleaning effect of the mahjong tiles to achieve a good cleaning effect. During the cleaning process, cleaning solution can be sprayed in. After cleaning for a certain period of time, the tiles are dried with the cleaning solution. Finally, clean mahjong tiles are obtained. Then, open the drawer, push the mahjong tiles into the drawer, take it to the mahjong machine and pour it into the mahjong machine. Then, take a set of mahjong tiles to be washed, put it in the drawer, take it to the mahjong washing machine, and pour it into the mahjong washing machine for cleaning.

[0061] The card shuffling machine of this application can not only clean mahjong tiles, but also other similar card games, such as chess, Go, international chess, Mongolian chess, Gomoku, checkers, international checkers, and military chess. Compared with currently available wet card shuffling machines on the market, this application has the following advantages:

[0062] 1. When used with cleaning solution, dry cleaning is more thorough and faster; 2. The hot air module provides drying, and the airflow from the hot air module combined with the rotation of the drum creates airflow inside the drum for quick and easy drying. Ventilation holes on the back of the drum facilitate moisture removal and further enhance drying efficiency; 3. The hot air module, water pump, and lighting panel are housed inside the door for easy installation and maintenance; 4. The transmission components feature speed ratio conversion, allowing a smaller motor to drive the drum and reducing energy consumption; 5. The outer and inner shells of the drum, the nylon brush roller, and the additional layer securing the inner shell are all made of soft materials, significantly reducing noise and scratches on the cards; 6. A drawer at the bottom increases the equipment's storage capacity. 7. The brush roller can be made of nylon filaments or a softer material for better cleaning. A covering layer similar in material to the brush roller, such as a nylon filament covering, can be added to the inner wall of the roller shell and the inner wall of the door. The nylon filament brush roller and the nylon filament covering layer are designed to be detachably connected to the roller and door, making installation and replacement more convenient. The relative dimensions of the brush roller and the inner shell of the roller can be tested and adjusted. Combined with the adjusted motor speed, frequency and duration of cleaning fluid spraying, and drying by the hot air module, optimal parameters are obtained for cleaning the cards, resulting in excellent cleaning effects. This application provides hardware and software optimization and subsequent modification space for cleaning cards, effectively cleaning them and exhibiting strong compatibility. By adjusting the speed, brush roller, material of the inner layer of the roller shell, cost of the cleaning fluid, and the relative ratio of the brush roller and the inner shell of the roller, it can accommodate different types of cards and achieve excellent cleaning results.

[0063] Example 2

[0064] like Figures 15-24 The shuffling machine in this embodiment consists of two parts: a main body and a front operating door, which contains various configuration devices.

[0065] The main body includes the exterior sheet metal, the roller base plate pivot support component, the roller support seat component, the roller component, and the motor component. The exterior sheet metal, together with the front panel, left side panel, right side panel, top cover, and rear cover, forms the main outer shell. Together with the base plate of the roller base plate pivot support component, it forms the housing of the card shuffling machine.

[0066] The front panel has a through hole corresponding to the roller. This through hole is surrounded by a front panel sealing ring, which can be made of silicone and has a certain hardness, such as a Shore hardness of 70. This sealing ring forms a closed groove outside the roller opening (the front end of the roller is recessed to form the roller opening). The roller opening does not contact the roller opening within this groove, which improves the overall sealing of the card shuffling machine and prevents debris from entering the machine body through the gap between the front panel and the roller, thus improving the safety of the card shuffling machine. At the same time, by covering the through hole of the front panel and the edge of the roller with the front panel sealing ring, the cards will not touch the edge of the through hole of the front panel and the edge of the roller during shuffling, which plays a buffering role in contact with the cards and reduces the damage to the cards during the shuffling process.

[0067] The roller base plate pivot support component includes a base plate, and the following components are installed on the base plate: left roller pivot support plate, right roller pivot support plate, left roller pivot mounting plate, right roller pivot mounting plate, left front roller support plate, right front roller support plate, and four wheels installed at the four corners of the base plate.

[0068] The left and right front roller support plates are respectively located below the front end of the roller. These front rollers support the front of the roller, preventing damage to the rear shaft caused by excessive force on the front during shuffling, thus improving the safety and stability of the equipment. In this way, the roller is supported by three points of force—the two front rollers on both sides and the central rear shaft. Compared to having no front rollers and relying solely on the central rear shaft for support, the roller shaft experiences more even force distribution, preventing easy wear on the shaft and extending the lifespan of the shuffling machine. Conventional rotary bearings are sufficient for the front rollers.

[0069] The base plate and the outer sheet metal together form the outer shell of the shuffling machine, and they are installed and fixed together by screws, which can be hex socket screws.

[0070] The left and right roller shaft support plates are fixedly installed on the base plate, near the rear of the shuffling machine. A motor assembly is fixedly installed between the left and right roller shaft support plates. The outer sides of the left and right roller shaft support plates are fixedly connected to the left and right roller shaft mounting plates. The bottom outer sides of the left and right roller shaft mounting plates are bolted to the raised ridge of the base plate. A roller support base assembly is fixedly connected between the upper parts of the left and right roller shaft mounting plates.

[0071] The base plate has multiple raised ridges for mounting different support plates. The left and right front roller support plates include a front support plate and a side support plate, which are at 90 degrees. The bottom of the front support plate is bent at 90 degrees and locked to the base plate with bolts. The side support plate is locked to the raised ridges of the base plate with bolts to ensure the stability of the left and right front roller support plates and prevent them from swaying back and forth or left and right.

[0072] Similarly, the left and right sides of the roller shaft mounting plate are provided with a front support plate and two side support plates. The front support plate and the two side support plates are at 90 degrees. The outer side support plate is locked onto the raised edge of the bottom plate, and the inner side support plate is locked onto the left and right sides of the roller shaft support plate.

[0073] The bottom and rear of the left and right sides of the roller shaft support plate each have 90-degree outward folds. The bottom folds are locked together with the base plate, and the rear folds are locked together with the motor mounting plate.

[0074] The above design ensures the stability of the roller base plate shaft support components, preventing swaying from side to side and back to front, thus providing stable support for the rotation of the roller.

[0075] The motor assembly includes a motor mounting plate, a motor, and a lower pulley. The motor mounting plate is installed at the rear between the left and right sides of the roller shaft support plate, and the three components together fix the motor in the middle. At the same time, the upper edge of the motor mounting plate is bent forward to form a horizontal section, which is used to fix the motor with bolts. This fixes the upper and rear ends of the motor together to the motor mounting plate. The two sides of the motor are clamped between the left and right sides of the roller shaft support plate, thus forming the motor and the roller base plate shaft support assembly into a whole, improving the stability of the motor installation.

[0076] The motor shaft passes through the fixed plate at the rear of the motor and is equipped with a lower pulley.

[0077] In the above roller base plate pivot support components, different components are divided by side plates that are 90 degrees to each other and 90-degree folded edges at the bottom, which improves the convenience of interlocking and installation of components and saves materials and space. It also brings about the structural stability of the overall roller base plate pivot support components, convenient locking and installation, and savings in raw material costs.

[0078] The roller support assembly includes: a roller rotating fixed seat, a roller support fixing component, and an upper pulley.

[0079] The roller rotating base includes a third bearing and a fourth bearing, with a certain length space reserved between the two bearings. The reason for using two bearings is that the front end of the shaft is the roller component, and the shaft needs to bear the downward weight of the roller component. Extending the length of the roller rotating base with two bearings allows the shaft passing through the base to bear a greater weight of the connected roller component, improving the stability and safety of the equipment. This allows the roller component to bear greater weight, and its operation is more stable. Combined with the previously mentioned front roller, this works together to support the stability of the roller component's operation and extend the service life of the shuffling machine. The bearing at the rear of the dual bearings can share the upward force from the front bearing due to the weight of the horizontal roller, making the dual bearing rotate more smoothly and also allowing it to bear a greater weight of the horizontal roller.

[0080] The roller support fastener includes a rear-end rotating shaft that matches the roller rotating fixed seat and a three-jaw structure that is fixedly connected to the front end of the roller component. The three claws firmly fix the roller component between the three claws. By setting connecting parts on the outer side and rear of the roller component, they are firmly fixed to the three-jaw structure. This fixing connection method can be welding or bolt locking. The three-jaw structure is distributed at 120 degrees apart, and the force distribution is uniform, which improves the stability of the roller component rotation. Symmetrical two-jaw (180 degrees apart), four-jaw (90 degrees apart), five-jaw (72 degrees apart) or more claws can also be set to uniformly fix the roller component.

[0081] The claw structure includes a horizontal part that contacts the outer wall of the roller and a vertical part that connects to a pre-set connecting plate on the outer wall of the roller. This design facilitates the clamping and installation of the roller, and the force on the roller rotation is more evenly distributed, improving the ease of roller installation and the firmness of roller installation.

[0082] The rear of the rotating shaft passes through the roller rotating base and is fixedly connected to the upper pulley. The upper pulley and the lower pulley of the motor are connected by a belt to provide power for the rotation of the roller assembly.

[0083] The roller component of this application not only includes a horizontal roller, but also optimizes and improves its structure. Specifically, it includes: a roller, a side roller brush fixing plate, a side roller brush rotating shaft, a side roller brush, and a main brush component; a square hole is opened at every 120 degrees on the cylindrical surface of the roller, and a side roller brush is installed in the square hole. The side roller brush has a side roller brush rotating shaft in the center. The front end of the side roller brush rotating shaft is directly inserted into the matching shaft hole of the roller, and the rear end is fixed in the square hole by the side roller brush fixing plate fixed to the rear of the roller. The purpose of setting the side roller brush fixing plate is to facilitate the installation of the side roller brush rotating shaft and the side roller brush. In actual installation, the side roller brush rotating shaft is first inserted into the side roller brush, then one end is installed into the matching shaft hole at the front end of the roller, and the rear end is installed into the side roller brush fixing plate. Finally, the side roller brush fixing plate is fixedly locked to the rear of the roller.

[0084] The main brush assembly is installed in the center of the roller. Both the main brush assembly and the side rollers have brushes attached to the outside of the rubber roller. For example, the main brush assembly has a rubber roller diameter of 5 cm and a brush length of 3.5 cm, while the side rollers have a rubber roller diameter of 5 cm and a brush length of 2 cm. In practice, the brush length and rubber roller diameter can be optimized through testing to achieve the best cleaning effect. The brush roller can be made of nylon filaments or a softer material for better cleaning performance.

[0085] The side roller brush allows the tiles to rotate along with the drum, making it easier for the tiles to tumble randomly within the drum. Simultaneously, the side roller brush, which is also a nylon bristle brush roller, rotates passively, ensuring the tiles come into contact with the nylon bristle brush roller for a more thorough cleaning. The drum outer shell of this application is made of PC material (polycarbonate) or similar material using a vacuum forming process, while the inner layer of the drum is made of OPE material (oxidized polyethylene wax) or similar material using a high-temperature molding process. This significantly reduces noise during drum shuffling. Furthermore, we have fixed a layer of cotton cloth inside the drum shell or covered the inner wall of the drum with nylon bristles, as well as the inner walls of the front and rear covers. This not only reduces noise but also prevents the mahjong tiles from scratching the inner wall of the drum during shuffling. The nylon bristle brush roller material is also more suitable for cleaning mahjong tiles than other brushes, and will not scratch the tiles.

[0086] The front operating door includes a front door cover and a front door rear cover, which together form a closed cavity, with a hot air drying unit, a cleaning spray unit and a UV lamp panel located between them.

[0087] The upper part of the front door cover has a front feeding port cover, which opens and closes by rotating up and down. This design allows the front feeding port cover to flip completely downwards when opened, saving space compared to a left-right flipping design. It also prevents the cover from automatically returning to its original position upon contact, making it easy to feed cards into the drum. The bottom of the front feeding port cover is hinged to the front door cover, and a magnet at the top engages with it. Opening it requires only a pull. This design allows the front feeding port cover to be opened even when the front operating door is closed, preventing cards from slipping out. This also contributes to the compact and elegant design of the washing machine, avoiding the problem of cards easily slipping out of the drum when the front operating door is opened, thus improving the washing machine's efficiency. After washing, simply open the front operating door to remove the cards.

[0088] A control panel is located in the upper left corner of the front operating door. Behind the control panel is a PCB control board used to control the shuffling machine. The control panel can be a touchscreen, allowing users to control the shuffling machine by touching various buttons. Touchscreen buttons include, for example: power on / off, run / pause, fast wash (white light), fine wash (white light), self-cleaning, etc. The corresponding commands are programmed onto the PCB control board to control the shuffling machine.

[0089] The hot air drying unit, cleaning spray unit, UV lamp panel 28, and motor module are connected to the PCB control board.

[0090] The front operating door opens to the left and right. The left side is connected to the front door panel via a hinge, and the right side is connected to the front door panel via a front door locking mechanism, thus enabling the front operating door to open and close. The front operating door is also equipped with an open-door power-off switch, which automatically cuts off the power supply when the front operating door is opened, improving the safety of the cleaning machine and preventing accidental opening of the front operating door or accidental operation of the cleaning machine while the front operating door is open, which could cause damage to the equipment.

[0091] The UV lamp panel can provide lighting inside the drum. Through program settings, the lamp can be automatically turned on when the front operating door or the front feeding port cover is opened, so as to make it easier to observe the situation inside the drum.

[0092] The front door and rear cover have lamp holes corresponding to the UV lamp panel. The air outlet of the hot air drying component is located at the corresponding position on the front door and rear cover. The hot air drying component provides hot air to dry the sign, and the cleaning spray component sprays cleaning fluid onto the sign for dry cleaning. Compared with wet cleaning, the cleaning is more thorough and efficient.

[0093] The cleaning spray components include: a cleaning sprayer, a spray extrusion mechanism rod, a spray cam, a spray pressurization support, a cleaning spray motor, a spray cover plate, and a spray control switch.

[0094] The spray cover is located on the rear cover of the front door. When the cleaning agent in the cleaning sprayer is used up, the spray cover is removed, the cleaning sprayer is taken out, refilled with cleaning agent, refilled, and then the spray cover is put back on.

[0095] The spray pressurization support is located at the bottom of the cleaning sprayer and is connected to one end of the spray extrusion mechanism rod. The other end of the spray extrusion mechanism rod is connected to the spray cam. The spray cam is powered by the cleaning spray motor to rotate and extrude the spray extrusion mechanism rod, which in turn drives the spray pressurization support to move up and down, thereby squeezing out the cleaning agent from the cleaning sprayer. The advantage of this structure is that it can be used with commonly used cleaning sprayers on the market without the need for mold opening of the cleaning sprayer structure, which improves the equipment compatibility of the cleaning machine. Moreover, the extrusion mechanism can achieve automatic spraying operation through program control.

[0096] A spray control switch is located at the lower end of one end of the spray extrusion mechanism rod. This switch counts the number of extrusions and can be programmed to start spraying at a specific time and stop spraying after a certain number of extrusions, thus achieving more precise and intelligent spray control. After the spray control switch counts, the remaining amount of cleaning agent can be displayed on the control panel based on the actual usage status of the cleaning agent according to the number of extrusions.

[0097] Usage: Place the mahjong tiles to be cleaned into the drum through the feed inlet. The ratio of the outer diameter of the nylon brush roller to the inner diameter of the drum can be designed, for example, 2:3. Different rotation speeds, varying the ratio of the outer diameter of the nylon brush roller to the inner diameter of the drum, combined with the appropriate rotation speed, will ensure the mahjong tiles are evenly distributed within the drum, allowing for thorough contact between the tiles and the nylon brush roller and the inner wall of the drum. This allows for testing the cleaning effect and effectively cleans the tiles. Cleaning solution can be sprayed during the cleaning process. After cleaning for a certain time until the tiles are clean, the cleaning solution is dried, resulting in clean mahjong tiles. The clean tiles are then removed, and another set of mahjong tiles is placed into the washing machine for further cleaning. This washing machine can clean not only mahjong tiles but also other similar board games, such as chess, Go, international chess, Mongolian chess, Gomoku, checkers, checkers, and military chess. Compared to currently available wet shuffling machines, this application has the following advantages:

[0098] 1. When used with cleaning solution, dry cleaning is more thorough and faster; 2. The hot air drying unit provides drying, and the airflow from the hot air drying unit, combined with the rotation of the drum, creates airflow inside the drum for convenient and rapid drying. Ventilation holes are located on the back of the drum to facilitate moisture removal and make drying more efficient.

[0099] 3. The hot air drying unit, cleaning spray unit, and UV lamp panel are installed inside the door for easy installation and subsequent maintenance; 4. The outer and inner shells of the roller, the nylon brush roller, and the inner shell of the roller are all made of soft materials, which greatly reduces noise and scratches to the cards; 5. The brush roller can be made of nylon or a softer material for better cleaning. The inner wall of the roller shell and the inner wall of the door can be covered with a layer of similar material to the brush roller, such as a nylon cover. The nylon brush roller and the nylon cover are designed to be detachably connected to the roller and the door, making installation and replacement more convenient. The relative dimensions of the brush roller and the inner shell of the roller can be tested and adjusted. Combined with the motor speed, the frequency and time of spraying cleaning fluid obtained through debugging, and the drying by the hot air drying unit, the optimal parameters are obtained for cleaning the cards, thus achieving a good cleaning effect. This application provides hardware and software optimization and subsequent modification space for cleaning cards, which can effectively clean the cards and has strong compatibility. By adjusting the rotation speed, brush roller, inner layer material of the roller shell, cleaning fluid cost, and the relative ratio of brush roller and roller shell, it can be compatible with cleaning different types of cards and achieve excellent cleaning results.

[0100] Example 3

[0101] like Figure 25 As shown, in Embodiment 2, a silicone layer can be fixedly adhered to the inner wall of the horizontal roller to cushion the tiles, such as mahjong tiles, during shuffling, preventing them from impacting the inner wall of the horizontal roller and causing damage. Furthermore, a velvet layer can be movably attached to the outside of the silicone layer, working in conjunction with the brush roller of the horizontal roller to rotate and wipe the tiles, further improving the cleanliness and efficiency of the tiles, while also providing secondary cushioning against the impact of the tiles on the inner wall of the horizontal roller. The silicone layer and the velvet layer can be movably connected by double-sided adhesive hook and loop fasteners. The adhesive side of the hook and loop fasteners is attached to the inner wall of the silicone layer and the bottom surface of the velvet layer, respectively. When the velvet layer needs to be replaced, it can be completely peeled off from the silicone layer and replaced with a brand new velvet layer with hook and loop fasteners.

[0102] Alternatively, the double-sided adhesive hook and loop fasteners can be replaced with a multi-set snap fastener structure, with multiple female snaps on the silicone layer and male snaps at the bottom of the corresponding position of the fleece layer to secure it.

[0103] To prevent the cards from contacting the inner wall of the roller during rotation, a silicone layer needs to be applied to every side wall of the horizontal roller that comes into contact with the cards, including the three side walls divided by the side roller brush and the bottom wall where the main brush is installed. In addition, a silicone layer and a velvet layer need to be adhered to the side of the front door and rear cover facing the horizontal roller in Embodiment 2. Thus, the entire space of the horizontal roller is filled with a silicone layer and a velvet layer, which not only improves the cleanliness and cleaning efficiency of the cards, but also prevents the cards from being scratched or bumped by the inner wall during the cleaning process.

[0104] Example 4

[0105] Many of the inventive structures in the previous embodiments of this application are also applicable to vertical rollers. For example, the silicone layer, the velvet layer, and the detachable connection method of the inner wall of the roller in Embodiment 3; the roller brush provided inside the roller in Embodiment 2, which includes a main brush and a secondary brush roller and corresponding specific structures; the front door panel sealing ring structure layout in Embodiment 2; the related structural design layout inside the door, especially the cleaning spray component structure layout; and the roller support fixing claw structure in Embodiment 2; all can produce similar effects, and will not be elaborated here.
