Description

Technical Field

[0001] This utility model relates to the field of card issuing devices, and in particular to a card storage slot for a card issuing device. Background Technology

[0002] Devices that process large numbers of cards (such as ATMs, ID card printers, ticket vending machines, etc.) often face severe stacking pressure problems. These devices have card issuing devices, which include card storage slots for storing cards, card outlets, card picking rollers for moving cards from the card storage slots to the card outlets, drive mechanisms for driving the card picking rollers, and drive motors.

[0003] In traditional card storage slots designed using the principle of a gravity feed system, the pressure between the bottom card and the card retrieval roller increases proportionally to the number of cards stacked. When the number of stacked cards reaches hundreds, it is very easy for insufficient friction between the card and the card retrieval roller to cause slippage, or for the friction torque between the cards to be greater than the motor torque, which is insufficient to carry the card out of the card outlet.

[0004] Known techniques for improving card insertion difficulties caused by large card stacks include:

[0005] 1. Card horizontal stacking method (refer to Chinese patent document CN102686404B), in which the card is placed horizontally above or below the machine body, and a support component is set in the card slot to push the support component to vertically dispensing the card. The structure is complex, and the card replacement requires opening and closing the cover. The difficulty of card replacement limits the flexibility of application fields.

[0006] Second, the card floats from bottom to top until it contacts the upper roller (refer to patent document CN103324960B). The cards are stacked under the machine body, which makes the machine too large. It also has the problems of complex structure and difficulty in replacing cards.

[0007] Third, the method of forcibly inserting the card by hooking the card (refer to patent document CN115626505B) has a complex structure and is limited by the thickness of the card, as well as the problem of scratching the card surface, which limits its application.

[0008] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0009] In view of the above, this utility model addresses the deficiencies of the existing technology and its main objective is to provide a card storage slot for a card issuing device. The slot body has a card storage cavity arranged sequentially from top to bottom and a docking cavity for connecting with the card issuing device. Within the card storage cavity, there is an inclined support portion for supporting the cards and reducing the accumulation of card weight. When cards are stacked within the slot body, the inclined support portion provides a normal reaction force to the cards. Simultaneously, friction is generated between the cards and the inclined support portion. The resultant force of the normal reaction force and the friction force can offset part of the card's weight upwards and also cancel the normal force between the cards, thereby reducing the friction between the cards. This structure reduces the accumulation of card weight, allowing the bottommost single card to be reliably removed by the card-retrieving roller with greater friction. The structure is simple and ingeniously designed.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A card storage slot for a card issuing device includes a card slot body. The card slot body has card storage cavities arranged sequentially from top to bottom and a docking cavity for engaging with the card issuing device. The card storage cavities have a card slot inlet, and the docking cavity has a card slot outlet on its side.

[0012] The card storage cavity has an inclined support for supporting the card and reducing the accumulation of card weight. The inclined support is located on one side of the card slot body together with the card slot outlet.

[0013] As a preferred embodiment, the inclined support includes a first inclined surface and a second inclined surface connected in sequence. The inclination angle of the second inclined surface is greater than that of the first inclined surface, so that the resultant force of the normal reaction force and the friction force of the second inclined surface is greater than the resultant force of the normal reaction force and the friction force of the first inclined surface.

[0014] As a preferred embodiment, the docking cavity has a third inclined surface for guidance. The third inclined surface is located on the opposite side of the card slot body and is partially located at the bottom of the card storage cavity. The inclination direction of the third inclined surface is opposite to the inclination direction of the inclined support. The third inclined surface also has the function of supporting the card and reducing the accumulation of card weight.

[0015] As a preferred embodiment, the card slot body has a replacement port on the opposite side that communicates with the card storage cavity for replacing cards.

[0016] As a preferred embodiment, the card slot body includes a left side plate, a front side plate, a right side plate, and a rear side plate. The left side plate, the front side plate, the right side plate, and the rear side plate together form a card storage cavity and a docking cavity. The card slot inlet is located at the top of the card slot body, the inclined support is disposed on the front side plate, and the replacement port is located on the rear side plate.

[0017] As a preferred embodiment, the left side panel, front side panel, right side panel, and rear side panel are integrally bent and connected. The rear side panel includes a first folded edge connected to the rear side of the left side panel and a second folded edge connected to the rear side of the right side panel. The replacement port is located between the first folded edge and the second folded edge.

[0018] As a preferred embodiment, the docking cavity is provided with a docking part for installation in conjunction with the card issuing device.

[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0020] The main feature is that the card slot body has a card storage cavity arranged from top to bottom and a docking cavity for connecting with the card issuing device. The card storage cavity has an inclined support part for supporting the card and reducing the accumulation of card weight. When the cards are stacked in the card slot body, the inclined support part can provide a normal reaction force to the card. At the same time, friction is generated between the card and the inclined support part. The resultant force of the normal reaction force and the friction force can offset part of the weight of the card upward and also offset the normal force between the cards, thereby reducing the friction between the cards. This structure reduces the accumulation of card weight, so that the bottom single card can be reliably taken out by the card picking roller with greater friction. The structure is simple and the design is ingenious.

[0021] Secondly, the docking cavity has a third inclined surface for guidance, which also has the function of generating an upward supporting force on the card, thereby reducing the accumulation of card weight, so that the bottom single card can be reliably removed.

[0044] First, it should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a card slot body 10.

[0046] The card slot body 10 is provided with a card storage cavity 101 and a docking cavity 102 arranged sequentially from top to bottom for docking with the card issuing device 20. The card storage cavity 101 is provided with a card slot inlet 103, and the docking cavity 102 is provided with a card slot outlet 104 on its side. The card storage cavity 101 has an inclined support part 30 for supporting the card and reducing the accumulation of card weight. The inclined support part 30 and the card slot outlet 104 are located on one side of the card slot body 10. In this embodiment, the card issuing device 20 is a card printer, but its specific application is not limited to this.

[0047] See Figure 1 and Figure 2 As shown, the card slot body 10 includes a left side plate 11, a front side plate 12, a right side plate 13, and a rear side plate 14. The left side plate 11, the front side plate 12, the right side plate 13, and the rear side plate 14 together form a card storage cavity 101 and a docking cavity 102. The card slot inlet 103 is located at the top of the card slot body 10, and the inclined support part 30 is disposed on the front side plate 12. Preferably, the left side plate 11, the front side plate 12, the right side plate 13, and the rear side plate 14 are integrally bent and connected, which makes the card slot body 10 easy to manufacture. The rear side plate 14 includes a first folded edge 141 connected to the rear side of the left side plate 11 and a second folded edge 142 connected to the rear side of the right side plate 13. The bottom of the first folded edge 141 and the second folded edge 142 are fixedly connected to a connecting block 143. The setting of the connecting block 143 can prevent the card slot body 10 from deforming under force.

[0048] See Figure 3 and Figure 4 As shown, the inclined support 30 includes a first inclined surface 301 and a second inclined surface 302 connected in sequence. The inclination angle of the second inclined surface 302 is greater than that of the first inclined surface 301. Regarding the specific effect of the upward supporting force generated by the inclined surfaces on the card, taking the first inclined surface 301 and the second inclined surface 302 as examples, the normal reaction forces generated by the first inclined surface 301 and the second inclined surface 302 on the card 40 are Na and Nb, respectively. The normal force Na generates a frictional force fa with the first inclined surface 301, and the normal force Nb generates a frictional force fb with the second inclined surface 302. The vector resultant forces of forces Na and Nb and frictional forces fa and fb are Fa and Fb, respectively. Since the inclination angle of the second inclined plane 302 is greater than that of the first inclined plane 301, the resultant force Fb is greater than the resultant force Fa. The upward components of the resultant forces Fa and Fb respectively offset part of the accumulated gravity of the card 40 and also offset part of the normal force between the cards, thereby reducing the frictional force between the cards. This minimizes the frictional force between adjacent cards at the card-taking point, so that the bottom single card can be reliably taken out by the card-taking roller with greater friction.

[0049] See Figure 2 and Figure 3 As shown, the front side plate 12 is arranged to be inclined backward. The inclined support part 30 includes a front support plate 31 and mounting plates 32 connected to both sides of the front support plate 31. The front support plate 31 is fixed to the front side plate 12 so that the front support plate 31 is inclined, thereby forming a first inclined surface 301 on the surface of the front support plate 31. The lower end of the front support plate 31 is formed by stamping and bending to form an inclined plate 33. The second inclined surface 302 is located on the surface of the inclined plate 33. The two mounting plates 32 are respectively fixed to the left side plate 11 and the right side plate 13. The bottom of the mounting plate 32 is provided with a docking part 321 for cooperating with the card issuing device 20. The docking part 321 is located in the docking cavity 102.

[0050] Specifically, the docking cavity 102 has a third inclined surface 105 for guiding and also for generating an upward supporting force on the card to reduce the accumulation of card weight. The third inclined surface 105 is located on the opposite side of the card slot body 10 and is partially located at the bottom of the card storage cavity 101. The inclination direction of the third inclined surface 105 is opposite to the inclination direction of the inclined support portion 30. The first folded edge 141 and the second folded edge 142 each have a first segment 106 and a second segment 107 arranged at a vertical distance. The first segment 106 is parallel to the front side plate 12 and is located at the card storage cavity 101. The second segment 107 is inclined forward. The third inclined surface 105 is located on the surface of the second segment 107. The second segment 107 is located at the docking cavity 102 and is partially located at the card storage cavity 101.

[0051] See Figure 2 As shown, on the opposite side of the card slot body 10, there is a replacement port 108 for replacing cards, which communicates with the card storage cavity 101, and a clearance port 109 for the card slot body 10 to avoid being installed in the docking cavity 102. The top of the clearance port 109 is connected to the bottom of the replacement port 108. When a card needs to be replaced, the operator can grab the card through the replacement port 108 and then take it out from the card slot inlet 103. The card replacement is convenient and the design is ingenious. Specifically, the replacement port 108 and the clearance port 109 are formed between the first folded edge 141 and the second folded edge 142. The width of the replacement port 108, the width of the clearance port 109, and the width of the card storage cavity 101 are gradually increased.

[0052] The key design feature of this utility model is:

[0053] The main feature is that the card slot body has a card storage cavity arranged from top to bottom and a docking cavity for connecting with the card issuing device. The card storage cavity has an inclined support part for supporting the card and reducing the accumulation of card weight. When the cards are stacked in the card slot body, the inclined support part can provide a normal reaction force to the card. At the same time, friction is generated between the card and the inclined support part. The resultant force of the normal reaction force and the friction force can offset part of the weight of the card upward and also offset the normal force between the cards, thereby reducing the friction between the cards. This structure reduces the accumulation of card weight, so that the bottom single card can be reliably taken out by the card picking roller with greater friction. The structure is simple and the design is ingenious.

[0054] Secondly, the docking cavity has a third inclined surface for guidance, which also has the function of generating an upward supporting force on the card, thereby reducing the accumulation of card weight, so that the bottom single card can be reliably removed.

[0055] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
