Description

Technical Field

[0001] This invention relates to a small card cleaning machine. Background Technology

[0002] In daily life and economic activities, various cards such as highway toll cards and bank cards are used very frequently. As the usage time increases, dirt will inevitably accumulate on the surface of these cards. When there are a large number of cards, manual cleaning is not only a huge workload, but also inefficient and consumes a lot of manpower and time. Therefore, the market urgently needs card cleaning equipment that can replace manual cleaning. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a small card cleaning machine that offers precise and efficient card pushing, comprehensive and efficient cleaning, suitable for use in small outlets and applicable to scenarios involving carrying and transporting cards.

[0004] To achieve the above objectives, the present invention first proposes a small card cleaning machine, including a card dispensing mechanism and a washing and drying unit. The card dispensing mechanism includes a support platform, a card pushing mechanism installed below the support platform, and a card dispensing box installed above the support platform and arranged perpendicularly to the support platform. The card dispensing box has openings at the top and bottom. The support platform has an elongated guide groove in the area covered by the lower opening of the card dispensing box. The guide groove connects the top and bottom sides of the support platform. The length of the guide groove is greater than the length of the card pushing area, so that the guide groove extends from the front and rear sides of the card dispensing box along the length direction. The bottom of the front and rear sides of the card dispensing box has a first inlet and a second inlet communicating with the guide groove, respectively. The first inlet and the second inlet are smaller than the size of the card to be cleaned, and the second inlet and the second inlet are not smaller than the size of the card to be cleaned. The washing and drying unit is installed on one side of the second inlet and the second inlet of the card dispensing mechanism. The washing and drying unit has a card inlet and a card outlet. The card inlet of the washing and drying unit is connected to the second inlet and the second inlet of the card dispensing box. The pusher of the card pushing mechanism is set in the guide groove and pushes the card to be cleaned in the card dispensing box from the second inlet and the second inlet into the card inlet of the washing and drying unit by reciprocating movement.

[0005] In this embodiment, the inner cavity of the card issuing box is matched in size with the card storage box, and the card storage box is detachably inserted into the card issuing box.

[0006] In this embodiment, the bottom of the card storage box is provided with a slot that matches the position and size of the guide groove, and the card storage box is provided with an opening that matches the position and size of the first inlet and outlet and the second inlet and outlet of the card issuing box; the inner cavity of the card storage box matches the size of the cards to be cleaned, and multiple cards to be cleaned are stacked vertically in the card storage box. After the card storage box is inserted into the card issuing box, the bottom of the card storage box is supported on the support platform, the slot of the card storage box coincides with the guide groove, and the inlet and outlet of the guide groove coincide with the first inlet and outlet and the second inlet and outlet, respectively.

[0007] In this embodiment, the card-pushing mechanism includes a card-pushing motor, a first transmission mechanism, and a push block. A guide shaft parallel to the guide groove is provided below the support platform. A slider is slidably connected to the guide shaft. The card-pushing motor drives the slider to move along the guide shaft via the first transmission mechanism. A rotating shaft perpendicular to the guide shaft and parallel to the support platform is provided on the slider. The push block is rotatably mounted on the rotating shaft. The top end of the push block is located in the guide groove, and the bottom end is located on the slider. The slider is provided with a limiting device to maintain the position of the push block when the card is being pushed. A torsion spring is also installed on the rotating shaft, causing the push block to return to its initial position after rotation. In the initial state, the top of the push block extends from the top surface of the support platform to form a pushing end, and the maximum length of the push block extending from the top surface of the support platform is not greater than the thickness of the card to be cleaned. In the pushing state, the push block enters from the first inlet and exits from the second inlet and exits. At this time, the push block remains stationary under the action of the limiting device. In the retracting state, the push block enters from the second inlet and exits from the first inlet and exits. At this time, the pushing end of the push block is driven to rotate and press down after being resisted by the card to be cleaned, so that the pushing end is housed in the guide groove. When the resistance of the pushing end of the push block is released, the push block returns to the initial state under the action of the torsion spring.

[0008] In this embodiment, the washing and drying unit includes a sealed cavity. At opposite ends of the sealed cavity are respectively an inlet and an outlet, both on the same horizontal plane and positioned opposite each other. Multiple partitions are provided within the sealed cavity, dividing it sequentially into a washing area, a cleaning area, and a drying area from the inlet to the outlet. Each partition has a connecting opening for the card to be cleaned to pass through. This connecting opening is opposite to the inlet and outlet and is on the same horizontal plane. A conveying mechanism is provided within the washing area, cleaning area, and drying area. This conveying mechanism is used to sequentially pass the card entering through the inlet through the washing area, cleaning area, and drying area, and then exit through the outlet.

[0009] In this embodiment, the conveying mechanism includes a first conveying roller group, a second conveying roller group, and a third conveying roller group respectively disposed in the washing zone, the cleaning zone, and the drying zone. The first conveying roller group, the second conveying roller group, and the third conveying roller group achieve simultaneous rotation in the same direction through a second transmission mechanism, which is driven by a main motor.

[0010] In this embodiment, the washing zone and the cleaning zone are respectively provided with a first brush roller and a second brush roller on the upper and lower sides of the conveying mechanism. The first brush roller and the second brush roller are linked to rotate in the same direction through a third transmission mechanism driven by the main motor. The washing zone and the cleaning zone are respectively provided with a washing liquid spray pipe and a cleaning liquid spray pipe at positions corresponding to the first brush roller and the second brush roller. The washing liquid spray pipe and the cleaning liquid spray pipe face the first brush roller and the second brush roller respectively. The washing liquid spray pipe is connected to the washing liquid pool outside through a washing liquid pump, and the cleaning liquid spray pipe is connected to the cleaning liquid pool outside through a cleaning liquid pump. The drying zone is provided with a hot air inlet and is connected to an external hot air generating device through the hot air inlet. The bottom of the washing zone, the cleaning zone and the drying zone are respectively provided with a first drain outlet, a second drain outlet and a third drain outlet. The bottom of the sealed cavity is provided with a drain trough that communicates with the first drain outlet, the second drain outlet and the third drain outlet.

[0011] In this embodiment, the rotation direction of the first brush roller and the second brush roller is opposite to the rotation direction of the first, second and third conveyor roller groups.

[0012] In this embodiment, a housing is also included. The housing is installed outside the card dispensing mechanism and the washing and drying unit. The housing encloses the outside of the card dispensing mechanism and the washing and drying unit. The card dispensing box extends from the top of the housing.

[0013] With the above structure, the present invention has the following advantages:

[0014] 1. This device achieves complete cleaning of the cards to be cleaned through the cooperation of the card dispensing mechanism and the washing and drying unit. The card dispensing mechanism is responsible for pushing the vertically stacked cards to be cleaned one by one into the washing and drying unit. The vertical stacking of the cards reduces the horizontal space occupied by the device. The washing and drying unit is responsible for washing, cleaning and drying the cards. The washing area, cleaning area and drying area are arranged side by side and are located in the same sealed cavity, which saves space while ensuring the cleaning effect.

[0015] 2. The card dispensing mechanism of this device is equipped with a card pushing mechanism. The card pushing mechanism works in concert with the card pushing motor, the first transmission mechanism and the push block. It uses a synchronous pulley set and synchronous belt transmission to drive the slider to move on the guide shaft, which in turn drives the push block to reciprocate. The top of the push block is located in the guide groove, and the initial extension length is no more than the thickness of the card. Combined with the design of the second inlet and outlet height, it ensures that only a single card is pushed out each time, avoiding the pushing out of multiple cards. At the same time, when the push block is retracting, it can be rotated and stored in the guide groove due to the resistance of the card. After the resistance is released, it returns to its original position under the action of the torsion spring, realizing precise card pushing and return to avoid collision, effectively improving the card pushing efficiency.

[0016] 3. Depending on the usage scenario and installation space, this device can be equipped with multiple card dispensing mechanisms and washing and drying units, thereby pushing multiple cards at once to achieve the washing of multiple cards, further improving the overall work efficiency.

[0017] 4. The card dispensing mechanism of this device adopts a support platform with a card dispensing box with openings at the top and bottom. The card storage box can be detached and inserted into the card dispensing box. Its bottom slot coincides with the guide slot of the support platform. This structure makes it easy to remove the card storage box separately, which is convenient for putting in and sorting the cards to be cleaned.

[0018] 5. The sealed chamber of the washing and drying unit of this device is divided into a washing zone, a cleaning zone, and a drying zone by a partition. The zones are connected by a connecting port. In the washing zone, the washing liquid spray pipe works with the first brush roller to wash and disinfect the cards to be cleaned using the washing liquid. In the cleaning zone, the cleaning liquid spray pipe works with the second brush roller to further clean the cards. The first and second brush rollers rotate in opposite directions to the conveyor roller group to enhance the cleaning effect. The drying zone is connected to an external hot air device through a hot air inlet to dry the cleaned cards. This clearly defined and collaborative design ensures that the cards receive comprehensive and thorough cleaning and drying.

[0019] In summary, the card storage box of this invention is easy to load and unload, pushes cards accurately and efficiently, coordinates washing and drying zones, and provides comprehensive and efficient cleaning. It is suitable for use in small outlets and can be applied to scenarios involving carrying and transporting. Attached Figure Description

[0028] like Figures 1 to 5As shown, a small card washing machine includes a card dispensing mechanism 1 and a washing and drying unit 3. The card dispensing mechanism 1 includes a support platform 12, a card pushing mechanism 2 installed below the support platform 12, and a card dispensing box 11 installed above the support platform 12. At least one card dispensing box 11 is fixed on the upper side of the support platform 12. The card dispensing box 11 is arranged perpendicularly to the support platform 12. The upper and lower openings and the inner cavity of the card dispensing box 11 are matched with the size of the card storage box 4. The support platform 12 has an elongated guide groove 13 in the area covered by the lower opening of the card dispensing box 11. The guide groove 13 connects the upper and lower sides of the support platform 12. The length of the guide groove 13 is greater than the length of the card pushing area, so that the guide groove 13 extends along the length of the card dispensing area. The card dispenser extends from the front and rear sides of the card dispenser 11 in a 3-degree direction. The bottom of the front and rear sides of the card dispenser 11 are respectively provided with a first inlet 14 and a second inlet 15 that communicate with the guide groove 13. The first inlet 14 is smaller than the size of the card to be cleaned 5, and the second inlet 15 is not smaller than the size of the card to be cleaned 5. The card storage box 4 is detachably inserted into the card dispenser 11. The washing and drying unit 3 is provided with a card inlet 38 and a card outlet 37. The card inlet 38 of the washing and drying unit 3 is connected to the second inlet 15 of the card dispenser 11. The card pushing mechanism 2 is used to push the card to be cleaned 5 in the card dispenser 11 from the second inlet 15 into the card inlet 38 of the washing and drying unit 3.

[0029] like Figure 5 As shown, the bottom of the card storage box 4 is provided with a slot that matches the position and size of the guide groove 13, and the card storage box 4 is provided with an opening that matches the position and size of the first inlet / outlet 14 and the second inlet / outlet 15 of the card issuing box; the inner cavity of the card storage box 4 matches the size of the card 5 to be cleaned when laid flat, and multiple cards 5 to be cleaned are stacked vertically in the card storage box 4. After the card storage box 4 is inserted into the card issuing box 11, the bottom of the card storage box 4 is directly supported on the support platform 12, the slot of the card storage box 4 coincides with the guide groove 13, and the inlet and outlet of the guide groove 13 coincide with the first inlet / outlet 14 and the second inlet / outlet 15, respectively.

[0030] like Figure 4As shown, the card-pushing mechanism 2 includes a card-pushing motor, a first transmission mechanism, and a push block 27. A guide shaft 26 parallel to the guide groove 13 is provided below the support platform 12. A slider 29 is slidably connected to the guide shaft 26. The card-pushing motor drives the slider 29 to move along the guide shaft 26 via the first transmission mechanism. A rotating shaft perpendicular to the guide shaft 26 and parallel to the support platform 12 is provided on the slider 29. The push block 27 is rotatably mounted on the rotating shaft. The top end of the push block 27 is located in the guide groove 13, and the bottom end is located on the slider 29. A limiting device is provided on the slider 29 to limit the initial position of the push block 27. A torsion spring 28 is also installed on the rotating shaft. One end of the torsion spring 28 is fixed to the slider 29, and the other end is fixed to the push block 27. The torsion spring 28 causes the push block 27 to rotate and return to its initial state. In the initial state, the top of the push block 27 extends from the top surface of the support platform 12 to form a pushing end, and the maximum length of the push block 27 extending from the top surface of the support platform 12 is not greater than the thickness of the card 5 to be cleaned. In the pushing state, the push block 27 enters from the first inlet / outlet 14 and exits from the second inlet / outlet 15. At this time, the push block 27 remains stationary under the action of the limiting device. In the retraction state, the push block 27 enters from the second inlet / outlet 15 and exits from the first inlet / outlet 14. At this time, the pushing end of the push block 27 is resisted and drives the push block 27 to rotate, so that the pushing end is housed in the guide groove 13. When the resistance of the pushing end of the push block 27 is released, the push block 27 returns to its initial state under the action of the torsion spring 28.

[0031] like Figure 2 , 4 As shown, the first transmission mechanism includes a first synchronous pulley group, a motor synchronous belt 22, a transmission shaft, a transmission synchronous belt 24, and a second synchronous pulley group. The first synchronous pulley group includes a first active synchronous pulley 21 and a first passive synchronous pulley 23. The second synchronous pulley group includes a second active synchronous pulley 251 and a second passive synchronous pulley 252. The first active synchronous pulley 21 is mounted on the output shaft of the push-card motor. The first passive synchronous pulley 23 and the second active synchronous pulley 251 are mounted at both ends of the same rotating shaft. The rotating shaft is rotatably mounted on the support platform 12. The motor synchronous belt 22 is installed between the first active synchronous pulley 21 and the first passive synchronous pulley 23. The second active synchronous pulley 251 and the second passive synchronous pulley 252 are rotatably mounted on the support platform 12 and below the guide shaft 26. The transmission synchronous belt 24 is installed between the second active synchronous pulley 251 and the second passive synchronous pulley 252. The transmission synchronous belt 24 is arranged parallel to the guide shaft 26. The slider 29 is fixed on the transmission synchronous belt 24.

[0032] like Figure 3As shown, the washing and drying unit 3 includes a sealed cavity 31. At opposite ends of the sealed cavity 31 are respectively provided an inlet 38 and an outlet 37 that are on the same horizontal plane and are opposite in position. The sealed cavity 31 is provided with multiple partitions 32. The partitions 32 divide the sealed cavity 31 into a washing area 33, a cleaning area 34 and a drying area 35 sequentially from the inlet 38 to the outlet 37. The partitions 32 are provided with a connecting opening for the card 5 to be cleaned to pass through. The connecting opening is opposite to the inlet and outlet and is on the same horizontal plane.

[0033] The washing zone 33, cleaning zone 34, and drying zone 35 are respectively equipped with a first conveyor roller group 332, a second conveyor roller group 342, and a third conveyor roller group 351. The first conveyor roller group 332, the second conveyor roller group 342, and the third conveyor roller group 351 achieve simultaneous rotation in the same direction through a second transmission mechanism. The second transmission mechanism is driven by a main motor. In this embodiment, the second transmission mechanism adopts a gear transmission mechanism. The first conveyor roller group 332, the second conveyor roller group 342, and the third conveyor roller group 351 are combined to form a conveying mechanism, which is used to transfer the incoming card... The card 5 to be cleaned enters the sealed cavity 31 through the outlet 38, passes through the washing area 33, the cleaning area 34, and the drying area 35 in sequence, and is sent out through the card outlet 37. The washing area 33 and the cleaning area 34 have a first brush roller 333 and a second brush roller 343 respectively installed on the upper and lower sides of the conveying mechanism. The first brush roller 333 and the second brush roller 343 rotate in the same direction through a third transmission mechanism, which is also driven by the main motor. In this embodiment, the third transmission mechanism also adopts a gear transmission mechanism. The rotation direction is opposite to that of the first, second, and third conveying roller groups, thereby improving the cleaning effect. Within the washing zone 33 and cleaning zone 34, washing liquid spray pipes 331 and cleaning liquid spray pipes 341 are respectively provided on the upper and lower sides corresponding to the positions of the first brush roller 333 and the second brush roller 343. The washing liquid spray pipes 331 and cleaning liquid spray pipes 341 face the first brush roller 333 and the second brush roller 343 respectively. Within the washing zone 33, through the cooperation of the washing liquid spray pipes 331 and the first brush roller 333, the washing liquid is used to achieve the washing and disinfection of the card 5 to be cleaned. Within the cleaning zone 34, the cleaning fluid spray pipe 341, in conjunction with the second brush roller 343, utilizes the cleaning fluid to clean the card 5 to be cleaned. The drying zone 35 is equipped with a hot air inlet, which is connected to an outer diameter hot air generating device. The bottoms of the washing zone 33, cleaning zone 34, and drying zone 35 are respectively provided with a first drain outlet 334, a second drain outlet 344, and a third drain outlet 352. The bottom of the sealing cavity 31 is provided with a drain trough 36 that communicates with the first drain outlet 334, the second drain outlet 344, and the third drain outlet 352.

[0034] like Figure 1As shown, it also includes a housing 6, which is installed on the outside of the card dispensing mechanism 1 and the washing and drying unit 3. The housing 6 encloses the outside of the card dispensing mechanism 1 and the washing and drying unit 3. The card dispensing box 11 extends from the top of the housing 6. The housing 6 has openings at the card dispensing port 37, the drain trough 36 and the corresponding positions of the water inlet pipe.

[0035] Using the above structure, the specific working process of this device is as follows:

[0036] First, the cards 5 to be cleaned are placed into the card storage box 4. The card storage box 4 is detachably installed in the card dispensing box 11 of the card dispensing mechanism 1, and the card storage box 4 can be easily removed to facilitate the placement of the cards 5 to be cleaned. After the card storage box 4 is placed into the card dispensing box 11, the card pusher motor receives a working command and drives the motor synchronous belt 22 to rotate through the first active synchronous belt pulley 21. The motor synchronous belt 22 drives the first passive synchronous belt pulley 23 to rotate. The first passive synchronous belt pulley 23 drives the second active synchronous belt pulley 251 to rotate through the rotating shaft. 251 and the second passive synchronous pulley 252 drive the transmission synchronous belt 24 to rotate, which in turn drives the slider 29, which is slidably mounted on the guide shaft 26, to move. This, in turn, drives the push block 27 on the slider 29 to reciprocate through the forward and reverse rotation of the pusher motor. Initially, the top of the push block 27 extends from the top surface of the support platform 12 to form a pushing end, and the maximum length of the push block 27 extending from the top surface of the support platform 12 is not greater than the thickness of the card 5 to be cleaned. During the card pushing state, the push block 27 enters from the first inlet / outlet 14 of the card dispensing mechanism 1 and exits from the second inlet / outlet 14. 5. When the card is in the outward position, the pusher 27 remains stationary under the action of the limiting device, thereby pushing the bottom card 5 to be cleaned in the card storage box 4 out from the second inlet / outlet 15 and into the card inlet 38 of the washing and drying unit 3. When in the retracted position, the pusher 27 enters from the second inlet / outlet 15 and exits from the first inlet / outlet 14. At this time, the pushing end of the pusher 27 contacts the bottom card 5 to be cleaned in the card storage box 4. Since the card 5 to be cleaned is larger than the size of the first inlet / outlet 14, the pushing end of the pusher 27 cannot push the card 5 to be cleaned. That is, the pushing end of the pusher 27 will be pushed by the card 5 to be cleaned. 5. Pressing down causes the pushing end to be housed in the guide groove 13, thereby realizing the avoidance action of the push block 27 when returning to its original position. After the resistance on the pushing end of the push block 27 is released, the push block 27 returns to its initial state under the action of the torsion spring 28. The height of the second inlet and outlet 15 of this application is greater than the height of one card but less than the height of two cards, ensuring that a single card can be pushed out smoothly without pushing out extra cards. After the push block 27 returns to its original position, the position sensor detects and waits. This embodiment is provided with three card dispensing mechanisms 1 and washing and drying unit 3, which can push three cards at a time, improving the cleaning efficiency.

[0037] After the card to be cleaned 5 is pushed into the inlet 38 of the washing and drying unit 3 from the second inlet / outlet 15 of the card dispensing mechanism 1 by the card pushing mechanism 2; the motor of the washing and drying unit 3 drives the first conveying roller group 332, the second conveying roller group 342 and the third conveying roller group 351 through the gear transmission mechanism to push the card to be cleaned 5 through the washing zone 33, the washing zone 34 and the drying zone 35 in sequence. The washing zone 33 pumps the washing liquid from the outside into the washing liquid spray pipe 331 through the washing liquid pump. The washing liquid spray pipe 331 sprays the washing liquid onto the card to be cleaned 5 and the first brush roller 333; the first brush roller 333 Driven by a motor, the card to be cleaned 5 rotates to achieve cleaning; the cleaned card 5 enters the cleaning zone 34, where the cleaning liquid pump pumps external cleaning liquid into the cleaning liquid spray nozzle 341; the cleaning liquid spray nozzle 341 sprays cleaning liquid onto the card to be cleaned 5 and the second brush roller 343, which rotates under the drive of a motor to further clean the card 5; the cleaned card 5 enters the drying zone 35, which is connected to an external hot air generator through a hot air inlet, and after drying, it is sent out through the card outlet 37, completing the cleaning process.

In the card pushing state, the push block enters from the first inlet and exits from the second inlet and exits. At this time, the push block remains stationary under the action of the limiting device. In the retraction state, the push block enters from the second inlet and exits from the first inlet and exits. At this time, the pushing end of the push block is driven to rotate and press down after being resisted by the card to be cleaned, so that the pushing end is housed in the guide groove. When the resistance of the pushing end of the push block is released, the push block returns to the initial state under the action of the torsion spring.
