Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of recreation equipment, in particular to an automatic card dispenser. BACKGROUND

[0002] The automatic card dispenser is a device capable of automatically and sequentially selling or distributing cards, which is applied to a card table, an arcade, a tabletop game auxiliary device and various entertainment terminals requiring automatic distribution of game cards, prop cards or prizes. The device can replace manual card dispensing to improve the level and efficiency of automatic service.

[0003] In the prior art, a common way is to set a friction card feeding mechanism below a stack of pre-stored cards. The mechanism usually adopts a single friction wheel or a card rubbing wheel, which is in contact with the bottom card through rotation, and separates and feeds the card from the card stack by using friction.

[0004] However, the traditional card dispenser using the single friction wheel card feeding mode has some defects in actual use: it is easy to cause card jamming or slipping, the contact area of the single friction wheel with the card is limited, the driving force provided by the single friction wheel acts on one side of the card, and if the friction force is insufficient or the surface of the card is smooth, the card may slip to cause card dispensing failure; at the same time, one-sided force may cause the card to deviate during feeding, thereby being stuck at the card outlet position and causing equipment failure. In addition, the friction wheel usually needs to be made of a material with high hardness or a rough surface, and a large pressure is applied to the card, which may scratch or wear the surface of the card in the long run, thereby affecting the normal use of the card.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0034] In addition, the terms "first", "second" and the like are mainly used to distinguish different devices, elements or components (the specific types and configurations may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "a plurality of" is two or more.

[0035] The technical scheme of the utility model will be further described below in combination with embodiments and drawings.

[0036] As shown in Figure 1 , 2 The utility model discloses an automatic card dispenser, which comprises:

[0037] Frame 1, frame 1 has the prestorage card stack groove 11 with the opening upwards on frame 1;

[0038] Card feeding assembly 2, card feeding assembly 2 is arranged below prestorage card stack groove 11, and is used for separating and feeding out the card closest to card feeding assembly 2 from the card stack;

[0039] Card sending assembly 3, card sending assembly 3 is arranged on frame 1, and card sending assembly 3 comprises first drive part 31, two first roller shafts 32 arranged in the vertical direction, the power output end of first drive part 31 is connected with two first roller shafts 32, card feeding assembly 2 sends the card to between two first roller shafts 32, the rotating direction of two first roller shafts 32 is opposite, and the card is sent out through the power of two first roller shafts 32, and the surface of first roller shaft 32 is provided with flexible friction layer 33.

[0040] Specifically, flexible friction layer 33 is made of rubber material.

[0041] Based on the above technical solution, two first rollers 32, spaced vertically and rotating in opposite directions, perform a double-sided clamping conveying of the cards fed by the card feeding assembly 2. This provides a balanced and stable driving force for the cards, effectively avoiding card skewing, slippage, and jamming caused by uneven force on one side, thereby improving the card issuance success rate and the operational reliability of the equipment. The surface of the first rollers 32 is provided with a flexible friction layer 33. This flexible layer material can increase the effective contact area between the first rollers 32 and the cards. With sufficient friction, the pressure on the cards is small, the force on the cards is more uniform, reducing scratches and wear on the card surface and extending the service life of the cards.

[0042] Preferably, the card feeding assembly 2 includes a second drive unit 21 and a second roller 22. The bottom of the pre-stored card stacking slot 11 is provided with a first passage 151. The second roller 22 is rotatably mounted on the frame 1. The power output end of the second drive unit 21 is connected to the second roller 22. The upper end of the second roller 22 protrudes from the first passage 151. The upper end of the second roller 22 can abut against the card closest to the second roller 22.

[0043] By opening a first through-hole 151 at the bottom of the pre-stored card stack slot 11 and making the upper end of the second roller shaft 22 protrude from the first through-hole 151, the driving force of the card feeding assembly 2 is ensured to act precisely on the card at the bottom of the card stack. Each time the second roller shaft 22 rotates, a single card can be separated from the card stack, thus improving the accuracy of card sorting.

[0044] The second roller 22 of the card feeding assembly 2 feeds the card a distance from the stationary card stack, so that its front end enters between the two first rollers 32 of the card issuing assembly 3. The card is clamped by the first rollers 32, and the card issuing assembly 3 takes over the subsequent transmission and ejection tasks. This staged processing method ensures the smoothness of the process from card feeding to card issuing.

[0045] More preferably, the frame 1 includes two side plates 12, a back plate 13, a partition 14, and a card carrier plate 15. The two side plates 12 are spaced apart along a first direction X, and the back plate 13 and the partition 14 are spaced apart along a second direction Y. The two ends of the back plate 13 and the partition 14 in the first direction X are respectively connected to the two side plates 12. The two ends of the card carrier plate 15 in the first direction X are respectively connected to the two side plates 12, and one end of the card carrier plate 15 in the second direction Y is connected to the back plate 13. There is a card slot between the card carrier plate 15 and the partition 14. A gap 16, two side plates 12, a back plate 13, and a partition 14 together enclose and define a pre-stored card stacking slot 11. A first passage 151 is opened on the card carrier plate 15. The two side plates 12 and the card carrier plate 15 together enclose and define an accommodating space 17. The first driving unit 31 includes a first driving motor 311, a first driving gear 312, a first driven gear 313, and a second driven gear 314. The first driving motor 311 is housed within the accommodating space 17. The first driving gear 312, the first driven gear 313, the first driven gear 314, the first driving motor 311 is housed within the accommodating space 17, the first driving gear 312, the first driven gear 313, the first driven gear 314, the first driven gear 315 ... A driven gear 313 and a second driven gear 314 are rotatably mounted on the outside of a side plate 12. The first driving gear 312 meshes with the first driven gear 313, and the first driven gear 313 meshes with the second driven gear 314. The power output end of the first drive motor 311 passes through the side plate 12 and connects to the first driving gear 312. The first driven gear 313 is coaxially fixed to a first roller shaft 32, and the second driven gear 314 is coaxially fixed to another first roller shaft 32. The second drive unit 2... 1 includes a second drive motor 211, a second drive gear 212 and a third driven gear 213. The second drive motor 211 is housed in the accommodating space 17. The second drive gear 212 and the third driven gear 213 are rotatably disposed on the outside of a side plate 12. The second drive gear 212 and the third driven gear 213 mesh with each other. The power output end of the second drive motor 211 passes through the side plate 12 and connects with the second drive gear 212. The third driven gear 213 is coaxially fixed with the second roller shaft 22.

[0046] In this context, the first direction X and the second direction Y are perpendicular to each other.

[0047] The frame 1, composed of side plates 12, back plates 13, partitions 14, and card carrier plates 15, not only defines the pre-stored card slot 11 for storing cards but also encloses a receiving space 17 below the card slot. Both drive motors are housed within this space, resulting in a compact overall structure and reduced external dimensions of the automatic card dispenser. Furthermore, physically isolating the drive motors from the cards prevents heat generated by the motors or dust from affecting the cards, and the fact that the drive motors do not directly contact the external environment extends the device's lifespan.

[0048] The first drive unit 31 engages with the first driven gear 313 via the first driving gear 312, and the first driven gear 313 engages with the second driven gear 314. One drive motor can drive two first roller shafts 32, mechanically ensuring that the two first roller shafts 32 rotate at exactly the same speed but in opposite directions. The forced synchronous reversal achieves smooth and non-skewed double-sided card feeding, which is more reliable than belt drive or two independent motor control, ensuring the stability of card issuance.

[0049] More preferably, the first drive unit 31 further includes a fourth driven gear 315 and a first connecting rod 316. The fourth driven gear 315 meshes between the first drive gear 312 and the second driven gear 314. One end of the first connecting rod 316 passes through the side plate 12 and is coaxially fixed with the fourth driven gear 315. The other end of the first connecting rod 316 is rotatably mounted on the other side plate 12. The second drive unit 21 further includes a fifth driven gear 214 and a second connecting rod 215. The fifth driven gear 214 meshes between the second drive gear 212 and the third driven gear 213. One end of the second connecting rod 215 passes through the side plate 12 and is coaxially fixed with the fifth driven gear 214. The other end of the second connecting rod 215 is rotatably mounted on the other side plate 12.

[0050] The two side plates 12 are connected together at the corresponding positions of the transmission structure by the first link 316 and the second link 215, forming a more stable structure that resists the deformation caused by the torque and vibration generated by the transmission structure, ensuring that the two side plates 12 can maintain strict parallelism and fixed spacing under any working state.

[0051] More preferably, the automatic card dispenser also includes a first photoelectric sensor 4. A second passage 131 is provided on the back plate 13 near the card carrier plate 15. The first photoelectric sensor 4 is disposed on the back plate 13 on the side opposite to the pre-stored card stacking slot 11 in the second direction Y. The detection end of the first photoelectric sensor 4 is directly opposite the second passage 131.

[0052] More preferably, the automatic card dispenser also includes a second photoelectric sensor 5, which is disposed on a side plate 12, and the detection end of the second photoelectric sensor 5 is located at the card dispensing end of the card dispensing assembly 3.

[0053] Based on the above technical solution, the automatic card dispenser is configured as follows:

[0054] The cards are stacked in the pre-stored card slot 11, and the height of the card stack is sufficient to block the second passage 131. Therefore, the light path of the first photoelectric sensor 4 is blocked, and the controller determines that the cards are sufficient. When the controller receives the card issuing command, it starts the second drive motor 211. The power is transmitted to the second roller 22 through the second drive gear 212, the fifth driven gear 214, and the third driven gear 213, causing it to rotate. The upper end of the second roller 22 rubs against and pushes the bottom card forward, passing through the card passage gap 16 between the card carrier plate 15 and the partition plate 14. When the front end of the card is fed between the two first rollers 32, the controller starts the second drive motor 211. A drive motor 311 and two first rollers 32 rotate synchronously in opposite directions, smoothly and quickly conveying the cards to the card dispensing end in a double-sided clamping manner. At this time, the second drive motor 211 can stop working. When the card is completely dispensed, it will pass through and briefly block the detection end of the second photoelectric sensor 5. The controller receives this signal change and can confirm that it is a successful card dispensing and complete the card dispensing task. As cards are continuously dispensed, when the card stack height decreases to the point where it can no longer block the second passage 131, the optical path of the first photoelectric sensor 4 is turned on. The controller receives this signal, determines that there are few cards or the cards are exhausted, and sends a request for card replenishment signal.

[0055] More preferably, the partition 14 includes a main board body 141 and a guide plate body 142 connected to the side, and the lower edge of the guide plate body 142 and the card carrier plate 15 together define a card passage gap 16.

[0056] In one specific embodiment, the guide plate 142 is an inclined surface that slopes towards the card issuing assembly 3. When the front end of the card is sent out, the guide plate 142 can actively and gently press the front end of the card downward so as to accurately align and smoothly enter the clamping area between the two first rollers 32, thereby improving the success rate of card delivery to card issuing and effectively avoiding card front end jamming.

[0057] More preferably, both the upper and lower ends of the side plate 12 are provided with mounting edges 121, and the mounting edges 121 are provided with mounting grooves 1211 and mounting holes 1212.

[0058] Users can install the automatic card dispenser on devices such as entertainment terminals and game desktops by using a bolt and screw structure and mounting grooves 1211 and mounting holes 1212 on the mounting outer edge 121.

[0059] In summary, this utility model embodiment provides an automatic card dispensing machine. Two first rollers 32, spaced vertically and rotating in opposite directions, perform a double-sided clamping conveying of cards from the card feeding assembly 2. This provides a balanced and stable driving force for the cards, effectively preventing card skewing, slippage, and jamming caused by uneven force on one side, thereby improving the card dispensing success rate and the operational reliability of the equipment. The surface of the first rollers 32 is provided with a flexible friction layer 33. This flexible layer material increases the effective contact area between the first rollers 32 and the cards. With sufficient friction, the pressure on the cards is relatively low, resulting in more uniform force distribution, reducing scratches and wear on the card surface, and extending the card's service life.

[0060] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
