Description

Technical Field

[0001] This utility model relates to the field of independent card issuing technology, and in particular to a card issuing machine. Background Technology

[0002] In self-dispensing card machines such as game card dispensers, stacked thin paper cards are dispensed by rotating a card-dispensing wheel. Due to the high friction between adjacent cards and between the cards and the card-dispensing wheel, the transmission wheel in the card conveying channel may slip before the previous card has completely detached from the card-dispensing wheel, preventing the card from being delivered smoothly. If the previous card has detached from the card-dispensing wheel, the card-dispensing wheel may accidentally push the card above it, sending both cards into the conveying channel at the same time, causing jamming or even scratching the cards. Utility Model Content

[0003] The main purpose of this utility model is to provide a card issuing machine that aims to solve the aforementioned technical problems.

[0004] To achieve the above objectives, the card issuing machine proposed in this utility model includes: A frame for stacking multiple cards; A drive assembly includes a timing pulley, which is rotatably mounted on the frame; A card-dispensing assembly, rotatably mounted on the frame, is used to drive the bottommost card among a plurality of cards to move. The clutch structure connects the card-dispensing assembly and the synchronous pulley and has a linked state and a non-linked state; in the linked state, the synchronous pulley can drive the card-dispensing assembly to rotate synchronously; in the non-linked state, the synchronous pulley stops driving the card-dispensing assembly to rotate, and the card-dispensing assembly can idle relative to the synchronous pulley.

[0005] In one embodiment, the card-dispensing assembly includes: The rotating shaft has two ends that pass through the frame and are rotatably connected to the frame, and the rotating shaft is connected to the synchronous pulley through the clutch structure; A card-dispensing wheel is sleeved on the outer circumference of the rotating shaft and rotates synchronously with the rotating shaft. The outer circumferential surface of the card-dispensing wheel is used to contact the card.

[0006] In one embodiment, the clutch structure includes a limiting groove and a pin. The limiting groove is disposed on the synchronous pulley and is arranged in a fan shape with the axis of the synchronous pulley as the center. One side wall of the limiting groove is configured as a pushing part. The pin is located at the end of the rotating shaft and protrudes from the side wall of the rotating shaft. The rotating shaft is coaxially arranged with the synchronous pulley, and the pin is located in the limiting groove. In the linkage state, the synchronous pulley rotates, causing the pushing part to drive the pin to rotate. In the non-linkage state, the pin rotates freely in the limiting groove.

[0007] In one embodiment, the drive assembly further includes a first drive motor disposed on the frame, the first drive motor being connected to the synchronous pulley via a synchronous belt.

[0008] In one embodiment, the card issuing machine further includes a first card transmission assembly, which includes a first pressure roller and a first card transmission roller arranged sequentially from top to bottom. The first card transmission roller is rotatably mounted on the frame, and a first transmission channel is provided between the first pressure roller and the first card transmission roller. In the linked state, the synchronous wheel rotates and drives the card-dispensing wheel to rotate, so that the card is conveyed toward the first transmission channel. When the card enters the first transmission channel, the card dispenser switches to the non-linked state, the synchronous wheel stops rotating, the first card transmission component drives the card to move away from the card-dispensing wheel, and the card drives the card-dispensing wheel and the rotating shaft to rotate relative to the synchronous wheel.

[0009] In one embodiment, the card issuing machine further includes a second card transmission assembly, which includes a second pressure roller and a second card transmission roller arranged sequentially from top to bottom. The second card transmission roller is rotatably mounted on the frame, and a second transmission channel is provided between the second pressure roller and the second card transmission roller.

[0010] In one embodiment, the card issuer further includes a drive module, the drive module comprising: A drive wheel, rotatably mounted on the frame; A second drive motor is disposed on the frame, and the second drive motor is drivenly connected to the drive wheel to drive the drive wheel to rotate. The first driven wheel is rotatably disposed on the outside of the frame, and the first driven wheel is coaxially connected to the first transmission wheel; The second driven wheel is rotatably located on the outside of the frame, and the second driven wheel is coaxially connected to the second transmission wheel; The driving wheel, the first driven wheel, and the second driven wheel are connected by a belt drive.

[0011] In one embodiment, the card issuing machine further includes: A card box is provided on the frame. A card outlet is provided on one side of the card box, which faces the first transmission channel. A connecting opening is provided on the bottom wall of the card box. The cards are placed inside the card box, so that the bottommost card is exposed at the connecting opening. A pressure block is provided inside the card box, and the pressure block is pressed against the upper end of the card.

[0012] In one embodiment, the card issuing machine further includes a limiting block and a protrusion. The limiting block is provided on the side of the card box with the card dispensing slot by fasteners and extends toward the bottom wall of the card box. The protrusion is provided on the bottom wall of the card dispensing slot, and the limiting block and the protrusion are spaced apart to form a card dispensing gap. The card dispensing gap is greater than the thickness of one card but less than the thickness of two cards.

[0013] In one embodiment, the limiting block is provided with an oblong hole, and the fastener passes through the oblong hole to connect with the card box.

[0014] In this invention, a synchronous wheel and a card-dispensing assembly are mounted on the frame. The card-dispensing assembly is coaxially connected to the synchronous wheel via a clutch mechanism, allowing the card-dispensing assembly and the synchronous wheel to have both linked and non-linked states. In the linked state, the synchronous wheel rotates, causing the card-dispensing assembly to rotate, which in turn moves the bottommost card. When the front end of a card enters another transmission channel and is moved by another power source, the card-dispensing assembly and the synchronous wheel switch to the non-linked state. The synchronous wheel stops rotating, and the card, during its movement, causes the card-dispensing assembly to idle relative to the synchronous wheel. This prevents friction between adjacent cards and between the card and the card-dispensing assembly. The friction between the cards is relatively high. Before the bottom card is completely detached from the card-dispensing assembly, the transmission wheel of the card-transfer channel slips, preventing the card from being sent out smoothly. After the bottom card is completely detached from the card-dispensing assembly, it no longer drives the card-dispensing assembly to rotate. Without the drive of the synchronous wheel, the card-dispensing assembly cannot rotate either. In other words, even if it comes into contact with the card on the second-to-last layer, it will not send out the card on the second-to-last layer without the card-dispensing assembly rotating. This prevents the card-dispensing assembly from dispensing the card on the bottom layer and sending both cards into the transmission channel at the same time, avoiding jamming or scratching of the cards. This improves the accuracy and stability of card issuance and enhances the user experience. Attached Figure Description

[0022] In self-dispensing card machines such as game card dispensers, stacked thin paper cards are dispensed by rotating a card-dispensing wheel. Due to the high friction between adjacent cards and between the cards and the card-dispensing wheel, the transmission wheel in the card conveying channel may slip before the previous card has completely detached from the card-dispensing wheel, preventing the card from being delivered smoothly. If the previous card has detached from the card-dispensing wheel, the card-dispensing wheel may accidentally push the card above it, sending both cards into the conveying channel at the same time, causing jamming or even scratching the cards.

[0023] This utility model proposes a card issuing machine.

[0024] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the card dispenser includes a frame 100, a drive assembly 200, a card dispensing assembly 300, and a clutch structure 400. The frame 100 is used to stack multiple cards 00. The drive assembly 200 includes a synchronous wheel 210, which is rotatably mounted on the frame 100. The card dispensing assembly 300 is rotatably mounted on the frame 100 and is used to drive the bottommost card 00 among the multiple cards 00 to move. The clutch structure 400 connects the card dispensing assembly 300 and the synchronous wheel 210 and has a linked state and a non-linked state. In the linked state, the synchronous wheel 210 can drive the card dispensing assembly 300 to rotate synchronously. In the non-linked state, the synchronous wheel 210 stops driving the card dispensing assembly 300 to rotate, and the card dispensing assembly 300 can rotate freely relative to the synchronous wheel 210.

[0025] In the technical solution of this utility model, a synchronous wheel 210 and a card-dispensing assembly 300 are provided on the frame 100. The card-dispensing assembly 300 is coaxially connected to the synchronous wheel 210 through a clutch structure 400, so that the card-dispensing assembly 300 and the synchronous wheel 210 have a linked state and a non-linked state. When in the linked state, the synchronous wheel 210 rotates, driving the card-dispensing assembly 300 to rotate. The rotation of the card-dispensing assembly 300 drives the bottommost card 00 to move. When the front end of the card 00 enters another transmission channel and is driven by other power, the card-dispensing assembly 300 and the synchronous wheel 210 switch to the non-linked state. The synchronous wheel 210 stops rotating, and the card 00 drives the card-dispensing assembly 300 to spin relative to the synchronous wheel 210 during the movement. This can prevent adjacent cards 00 from spinning freely or between cards 00 and other cards. The friction between the card-dispensing components 300 is relatively large. When the bottom card 00 has not completely detached from the card-dispensing component 300, the transmission wheel of the card transmission channel slips and cannot smoothly send the card 00 out. After the bottom card 00 completely detaches from the card-dispensing component 300, it no longer drives the card-dispensing component 300 to rotate. Without the drive of the synchronous wheel 210, the card-dispensing component 300 cannot rotate. That is, even if it comes into contact with the second-to-last card, it will not send out the second-to-last card without the card-dispensing component 300 rotating. This prevents the card-dispensing component 300 from dispensing the card 00 after it detaches from the bottom card and then dispensing the card to the top card, sending both cards into the transmission channel at the same time. This avoids jamming or scratching the card 00, improves the accuracy and stability of card issuance, and enhances the user experience.

[0026] Specifically, the frame 100 includes a bottom support plate and upright plates on both sides of the top of the support plate, which provide the mounting base for the entire card dispenser. The card dispensing assembly 300 is rotatably mounted on the frame 100, and its outer circumference is textured to increase the friction between it and the card 00, ensuring that the card dispensing assembly 300 can drive the card 00 to move when it rotates. The synchronous wheel 210 is rotatably mounted on the outside of the upright plate through a bearing, so that the synchronous wheel 210 can be moved outside the frame 100, ensuring that the synchronous wheel 210 can rotate smoothly. The synchronous wheel 210 is coaxially arranged with the card dispensing assembly 300. In the linkage state, the rotation of the synchronous wheel 210 can drive the card dispensing assembly 300 to rotate, thereby conveying the card 00. Specifically, the synchronous wheel 210 can be driven by a handwheel or by a motor, which is not limited here.

[0027] In an embodiment of this utility model, the card-dispensing assembly 300 includes a rotating shaft 320 and a card-dispensing wheel 310. The two ends of the rotating shaft 320 pass through the frame 100 and are rotatably connected to the frame 100. The rotating shaft 320 is connected to the synchronous wheel 210 through a clutch structure 400. The card-dispensing wheel 310 is sleeved on the outer periphery of the rotating shaft 320 and rotates synchronously with the rotating shaft 320. The outer peripheral surface of the card-dispensing wheel 310 is used to contact the card 00.

[0028] Specifically, the card-dispensing wheel 310 is sleeved on the outer circumference of the rotating shaft 320 and rotates synchronously with the rotating shaft 320. Both ends of the rotating shaft 320 are rotatably connected to a vertical plate via bearings, and one end of the rotating shaft 320 is engaged with a clutch structure 400, allowing the card dispenser to be in both a linked and non-linked state. When the card dispenser is in the linked state, the synchronous wheel 210 rotates, driving the rotating shaft 320 to rotate, which in turn drives the card-dispensing wheel 310 to rotate. The outer circumference of the card-dispensing wheel 310 contacts the bottommost card 00, causing the card 00 to move towards the card dispensing slot. At this time, due to the connection effect of the clutch structure 400, the card-dispensing assembly 300 and the synchronous wheel 210 maintain synchronous rotation, ensuring that the card 00 can smoothly enter the card dispensing slot.

[0029] In an embodiment of this utility model, the clutch structure 400 includes a limiting groove 410 and a pin 420. The limiting groove 410 is disposed on the synchronous pulley 210 and is arranged in a fan shape with the axis of the synchronous pulley 210 as the center. One side wall of the limiting groove 410 is configured as a pushing part 411. The pin 420 is disposed at the end of the rotating shaft 320 and protrudes from the side wall of the rotating shaft 320. The rotating shaft 320 is coaxially disposed with the synchronous pulley 210, and the pin 420 is disposed in the limiting groove 410. In the linkage state, the synchronous pulley 210 rotates, causing the pushing part 411 to drive the pin 420 to rotate. In the non-linkage state, the pin 420 rotates freely in the limiting groove 410.

[0030] Specifically, such as Figure 2 As shown, the limiting groove 410 is fan-shaped, and the specific fan angle depends on the distance between the card-dispensing wheel 310 and the front-end card-transfer assembly. One side wall of the limiting groove 410 is configured as a pushing part 411, and the other side wall is configured as a stopping part 412. The pin 420 passes radially through the outer periphery of the rotating shaft 320 and protrudes from the outer wall of the rotating shaft 320. When in the linkage state, as... Figure 2 As shown, pin 420 is close to push part 411, synchronous wheel 210 rotates counterclockwise, push part 411 pushes pin 420 and rotating shaft 320 to rotate counterclockwise, thereby driving card-dispensing wheel 310 to rotate counterclockwise. Card-dispensing wheel 310 drives card 00 to be conveyed to the left. When card-dispensing wheel 310 only contacts the tail end of card 00, if card-dispensing wheel 310 continues to rotate and drive card 00 to move, it is easy to push the second-to-last layer of cards 00 together. At this time, synchronous wheel 210 stops rotating, and card 00 continues to move forward at the front end due to other forces, which can pull card-dispensing wheel 310 to rotate, and drive rotating shaft 320 and pin 420 to rotate synchronously. Pin 420 moves in the direction of stop part 412 in the limiting groove 410, as... Figure 3 and Figure 5As shown, the process continues until the bottom card 00 is completely disengaged from the card-dispensing wheel 310. When the card-dispensing wheel 310 contacts the second-to-last card 00, the synchronous wheel 210 is activated, causing it to rotate counterclockwise. This causes the pushing part 411 of the limiting groove 410 to approach the pin 420, pushing the pin 420, the rotating shaft 320, and the card-dispensing wheel 310 to rotate. This, in turn, drives the bottom card 00 to be conveyed to the left again. This cycle allows for the sequential dispensing of single cards 00, preventing the simultaneous dispensing of two cards. This effectively solves the problems of jamming and card scratches in traditional card dispensers, reduces unnecessary friction and wear, and improves the service life and stability of the card dispenser.

[0031] In addition, such as Figure 2 and Figure 3 As shown, two limiting grooves 410 can be provided and are arranged symmetrically around the axis of the synchronous pulley 210. The two limiting grooves 410 are connected at the axis of the synchronous pulley 210. The two ends of the pin 420 pass through the outer circumference of the rotating shaft 320 respectively, and the two ends of the pin 420 are located in one limiting groove 410 respectively, so as to realize relative rotation within the limiting groove 410 or rotation with the synchronous pulley 210.

[0032] Please refer to Figure 1 and Figure 6 In an embodiment of this utility model, the drive assembly 200 further includes a first drive motor 220 disposed on the frame 100. The first drive motor 220 is connected to the synchronous pulley 210 via a synchronous belt 230. The first drive motor 220 is mounted on one of the upright plates and located between the two upright plates. The synchronous pulley 210 is located on the outside of the upright plate. The output shaft of the first drive motor 220 passes through the upright plate and is coaxially connected to an output wheel. The output wheel and the synchronous pulley 210 are connected via a synchronous belt 230 so that the first drive motor 220 drives the synchronous pulley 210 to rotate, thereby driving the card-dispensing wheel 310 to rotate, thereby realizing the dispensing of the card 00.

[0033] Please refer to Figure 6 In an embodiment of this utility model, the card issuing machine further includes a first card transmission component 500. The first card transmission component 500 includes a first pressure roller 510 and a first card transmission roller 520 arranged sequentially from top to bottom. The first card transmission roller 520 is rotatably mounted on the frame 100. A first transmission channel is provided between the first pressure roller 510 and the first card transmission roller 520. In the linkage state, the synchronous wheel 210 rotates and drives the card-dispensing wheel 310 to rotate, so that the card 00 is conveyed toward the first transmission channel. When the card 00 enters the first transmission channel, the card issuing machine switches to a non-linkage state, the synchronous wheel 210 stops rotating, and the first card transmission component 500 drives the card 00 to move away from the card-dispensing wheel 310. The card 00 drives the card-dispensing wheel 310 and the rotating shaft 320 to rotate relative to the synchronous wheel 210.

[0034] Specifically, the first pressure roller 510 and the first card transfer roller 520 form a first transmission channel. After the card 00 moves away from the card transfer roller 310, it enters the first transmission channel. The first pressure roller 510 presses down on the first card transfer roller 520, causing the first card transfer roller 520 to generate friction with the card 00 while rotating, thus realizing the transmission of the card 00. Figure 4 As shown, when the first end of the bottom card 00 enters the first transmission channel and contacts the first card-transfer wheel 520, the tail end has not yet disengaged from the card-dispensing wheel 310. At this time, the synchronous wheel 210 stops rotating. As the first card-transfer wheel 520 rotates, driving the card 00 to continue moving away from the card-dispensing wheel 310, the movement of the card 00 drives the card-dispensing wheel 310 to rotate. At this time, the card-dispensing wheel 310 rotates freely relative to the synchronous wheel 210. The pin 420 on the end of the rotating shaft 320 rotates in the limiting groove 410 and moves away from the pushing part 411, rotating towards the other side wall of the limiting groove 410, that is, the stop part 412. Figure 5 As shown, when the pin 420 rotates to near the stop 412, the card 00 disengages from the card-dispensing wheel 310. The movement of the card 00 no longer applies power to the card-dispensing wheel 310, and the card-dispensing wheel 310 no longer idles relative to the synchronous wheel 210. At this time, the card-dispensing wheel 310 contacts the second-to-last layer of cards 00. When the bottom layer of cards 00 completely disengages from the first transmission channel, the first drive motor 220 drives the synchronous wheel 210 to rotate, causing the pushing part 411 to approach the pin 420, and then pushes the pin 420, the rotating shaft 320, and the card-dispensing wheel 310 to rotate until the card 00 re-enters the first transmission channel. This effectively avoids the problem of the card-dispensing wheel 310 slipping or two cards being sent into the first transmission channel at the same time due to excessive friction during the card 00 dispensing process, realizing the continuous dispensing of a single card 00 and improving the stability and reliability of the card dispenser.

[0035] In an embodiment of this utility model, the card issuing machine further includes a second card transmission assembly 600. The second card transmission assembly 600 includes a second pressure roller 610 and a second card transmission roller 620 arranged sequentially from top to bottom. The second card transmission roller 620 is rotatably mounted on the frame 100, and a second transmission channel is provided between the second pressure roller 610 and the second card transmission roller 620.

[0036] like Figure 6 As shown, specifically, the second card transfer component 600 is located on the side of the first card transfer component 500 away from the card dispensing wheel 310. The structure of the second card transfer component 600 is similar to that of the first card transfer component 500. When the card 00 passes through the first transmission channel, it will be transferred towards the second transmission channel. Since the second pressure wheel 610 presses the card 00 against the second card transfer wheel 620, as the second card transfer wheel 620 rotates, it will transport the card 00 away from the first transmission channel. Together with the first card transfer component 500, it improves the continuity and stability of card dispensing of the card issuing machine.

[0037] In addition, by adjusting the rotation direction of the second card-transfer wheel 620 and the first card-transfer wheel 520, such as rotating counterclockwise, the card-receiving action of the card dispenser can be achieved.

[0038] Please refer to Figure 1 and Figure 6 In an embodiment of this utility model, the card issuing machine further includes a drive module 700, which includes a drive wheel 710, a second drive motor 720, a first driven wheel 730, and a second driven wheel 740. The drive wheel 710 is rotatably mounted on the frame 100; the second drive motor 720 is mounted on the frame 100 and is drivenly connected to the drive wheel 710 to drive the drive wheel 710 to rotate; the first driven wheel 730 is rotatably mounted on the outside of the frame 100 and is coaxially connected to the first card-transfer wheel 520; the second driven wheel 740 is rotatably mounted on the outside of the frame 100 and is coaxially connected to the second card-transfer wheel 620; wherein the drive wheel 710, the first driven wheel 730, and the second driven wheel 740 are connected by a belt 750.

[0039] Specifically, the driving wheel 710, the first driven wheel 730, and the second driven wheel 740 are all rotatably mounted on one of the vertical plates. A second drive motor 720 is also mounted on this vertical plate. The second drive motor 720 is coaxially connected to the driving wheel 710 and drives the driving wheel 710 to rotate. Since the driving wheel 710, the first driven wheel 730, and the second driven wheel 740 are connected by a belt 750, the rotation of the driving wheel 710 will drive the first driven wheel 730 and the second driven wheel 740 to rotate synchronously in the same direction. Figure 1 As shown, the first driven wheel 730 is coaxially connected to the first card-transfer wheel 520 via a first card-transfer shaft, and the second driven wheel 740 is coaxially connected to the second card-transfer wheel 620 via a second card-transfer shaft. The first driven wheel 730 and the second driven wheel 740 rotate clockwise, driving the first card-transfer wheel 520 and the second card-transfer wheel 620 to rotate clockwise. The first card-transfer assembly 500 and the second card-transfer assembly 600 work together to achieve stable transmission of card 00. During the transmission of card 00, the first pressure wheel 510 cooperates with the first card-transfer wheel 520 and the second pressure wheel 610 cooperates with the second card-transfer wheel 620 to press the card 00, ensuring that the card 00 will not deviate or jam during transmission, thereby improving the stability and continuity of the card dispenser. Furthermore, by setting a drive motor and belt 750 for transmission, the power structure is reduced, and the rotation of the two card-transfer assemblies can be driven by a single power source, which facilitates the lightweighting of the structure.

[0040] Please refer to Figure 1 and Figure 6In an embodiment of this utility model, the card issuing machine further includes a card box 800 and a pressing block 810. The card box 800 is disposed on the frame 100. A card outlet is provided on one side of the card box 800, facing the first transmission channel. A connecting port is provided on the bottom wall of the card box 800. The card 00 is disposed inside the card box 800, so that the bottommost card 00 is exposed at the connecting port. The pressing block 810 is disposed inside the card box 800 and presses down on the upper end of the card 00.

[0041] Specifically, the card box 800 is mounted on the frame 100. The card box 800 may include a base plate, a front plate and a rear plate mounted on top of the base plate, and two side plates. The two side plates are spaced apart, and the side plates, base plate, front plate, and rear plate form a receiving cavity. Multiple stacked cards 00 are placed in the receiving cavity, such as... Figure 6 As shown, a connecting port is provided on the base plate, so that the bottom card 00 is exposed at the connecting port. The card-dispensing wheel 310 is located below the base plate and passes through the connecting port to contact the bottom card 00. When the card-dispensing wheel 310 rotates, it can dispense the card 00 through the friction between itself and the card 00. The front plate is located near the first card-transfer assembly 500, and there is a gap between the bottom of the front plate and the base plate. This gap is configured as a card dispensing port. The card 00 is conveyed toward the card dispensing port by the rotation of the card-dispensing wheel 310. In addition, a pressure block 810 is provided in the card box 800 to press on the cards 00, applying gravity to the stacked cards 00 to ensure that the card-dispensing assembly 300 can accurately contact the bottom card 00. This ensures that the card-dispensing wheel 310 can send out the bottom card 00 through rotational friction, preventing the cards 00 from being scattered due to external forces or their own gravity, which would cause the card-dispensing wheel 310 to slip. This improves the stability and continuity of the card dispensing machine.

[0042] Please refer to Figure 5 and Figure 6 In an embodiment of this utility model, the card issuing machine further includes a limiting block 820 and a protrusion 801. The limiting block 820 is fastened to the side of the card box 800 where the card outlet is located and extends toward the bottom wall of the card box 800. The protrusion 801 is located on the bottom wall of the card outlet. The limiting block 820 and the protrusion 801 are spaced apart to form a card dispensing gap. The card dispensing gap is greater than the thickness of one card 00 and less than the thickness of two cards 00.

[0043] Specifically, the card dispensing slot is located on the front side of the card box 800, i.e., the first card transmission component 500 is located there. The limiting block 820 is correspondingly located on the front side of the card box 800 and extends towards the bottom wall, forming a card dispensing gap with the protrusion 801 on the bottom wall of the card dispensing slot. The card dispensing gap is set to be greater than the thickness of one card 00 but less than the thickness of two cards 00, effectively preventing the simultaneous dispensing of two cards or card 00 jamming during the card dispensing process. When the bottom card 00 moves towards the card dispensing slot under the rotation of the card dispensing wheel 310, only one card 00 can pass through the card dispensing gap smoothly due to the limitation of the card dispensing gap, while the cards 00 stacked above are blocked by the limiting block 820 and cannot enter the card dispensing gap at the same time. This ensures that only one card 00 can be accurately dispensed each time, improving the accuracy and stability of card dispensing.

[0044] Please refer to Figure 1 In this embodiment of the utility model, the limiting block 820 is provided with an oblong hole 821. The fastener passes through the oblong hole 821 and is connected to the card box 800. The oblong hole 821 extends in the vertical direction. By adjusting the contact position between the fastener and the oblong hole 821, the relative position of the limiting block 820 in the vertical direction on the card box 800 can be adjusted, thereby adjusting the size of the card dispensing gap. This is suitable for the card dispensing needs of cards 00 of different thicknesses, improving the applicability of this solution. Moreover, the adjustment method is simple and does not require the entire card dispensing machine to be disassembled and reassembled.

[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
