Description

Technical Field

[0001] The utility model belongs to the technical field of shuffling machines and relates to a card-lifting structure of a shuffling machine. Background Art

[0002] Playing cards, as the most common entertainment items in people's lives, are deeply loved by the general public because of their diverse playing methods and suitability for all ages. However, after a game of cards, players need to sort, shuffle, and deal the cards by themselves. In order to save the time of dealing cards, various machines that replace manual card dealing have emerged, greatly improving the experience of poker games.

[0003] In the existing shuffling machines, at the last stage of shuffling, the cards need to be lifted from the card bin to the top through a card-lifting structure for easy picking and placing. The entire card-lifting process needs to ensure its stability and speed. However, the existing card-lifting mechanisms of shuffling machines generally work in a chain drive mode, with poor stability, affecting the user experience, and having great room for improvement. Summary of the Invention

[0004] The purpose of the utility model is to propose a card-lifting structure of a shuffling machine for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A card-lifting structure of a shuffling machine, comprising:

[0006] A base;

[0007] A card-lifting plate provided with at least two threaded holes;

[0008] At least two lead screws, the lead screws are rotatably connected to the base, each lead screw is threadedly connected to each threaded hole, and the lead screws are provided with driven wheels;

[0009] A synchronous drive assembly, which includes a driving element and a transmission member. The driving element is connected to the base, the output shaft of the driving element is provided with a driving wheel, and the driven wheels of each lead screw are all connected to the driving wheel through the transmission member. The driving element can drive the transmission member through the driving wheel to drive each driven wheel to rotate, and drive the card-lifting plate to lift and lower through the rotation of the lead screws.

[0010] In the above card-lifting structure of a shuffling machine, the transmission member is a synchronous belt, the driven wheel is in contact with the synchronous belt, and the driving wheel is in contact with the synchronous belt.

[0011] In the above card-lifting structure of a shuffling machine, the synchronous belt is a closed-loop structure, the synchronous belt is sleeved on the driving wheel and each driven wheel, and the driving wheel and each driven wheel are all located inside the synchronous belt.

[0012] In the above-mentioned card-lifting structure of a shuffling machine, an idler wheel is further included. The idler wheel contacts the outer side of the synchronous belt, and the idler wheel is located in the enclosed space formed between the driving wheel and each driven wheel, so that the synchronous belt bends towards its own interior.

[0013] In the above-mentioned card-lifting structure of a shuffling machine, the synchronous belt is a toothed belt, the driven wheel is a first gear, the driving wheel is a second gear, the driven wheel meshes with the synchronous belt, and the driving wheel meshes with the synchronous belt.

[0014] In the above-mentioned card-lifting structure of a shuffling machine, the transmission member is a transmission gear set, the driven wheel is a third gear, the driving wheel is a fourth gear, the driven wheel meshes with the transmission gear set, and the driving wheel meshes with the transmission gear set.

[0015] In the above-mentioned card-lifting structure of a shuffling machine, the angular velocities of all the driven wheels are the same.

[0016] In the above-mentioned card-lifting structure of a shuffling machine, the card-lifting plate is further provided with a nut, and the threaded hole is located in the nut.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. The driving element can drive the transmission member through the driving wheel to drive each driven wheel to rotate, and drive the card-lifting plate to lift and lower through the rotation of the lead screw. Due to the synchronization of the lead screw rotation, the forces on each position of the card-lifting plate are evenly and stably distributed, thus realizing the stable lifting and lowering of the card-lifting plate.

[0021] 2. Since the lead screw transmission itself has a relatively large transmission ratio, there is no need to design a complex deceleration structure to ensure that the card-lifting plate has sufficient load-bearing capacity when rising.

[0022] 3. The synchronous belt is sleeved on the driving wheel and each driven wheel, so as to increase the contact between the synchronous belt and the driving wheel and each driven wheel through tensioning, thereby ensuring the transmission efficiency among the driving wheel, the synchronous belt and the driven wheels.

[0023] 4. The idler wheel is located in the enclosed space formed between the driving wheel and each driven wheel, so that the synchronous belt bends towards its own interior, increasing the contact area between the synchronous belt and the driving wheel or the driven wheel, and ensuring the transmission efficiency between the driving wheel and the driven wheel.

[0024] 5. The synchronous belt is a toothed belt, the driven wheel is a first gear, the driving wheel is a second gear, the driven wheel meshes with the synchronous belt and the driving wheel meshes with the synchronous belt, and the transmission efficiency among the driving wheel, the synchronous belt and the driven wheel is ensured through toothed transmission.

[0036] Embodiment 1

[0037] As Figures 1 - 4 shown, a card-lifting structure of a shuffling machine includes: a base 100, a card-lifting plate 200, a lead screw 300, and a synchronous drive assembly 400.

[0038] Among them, the card-lifting plate 200 is provided with at least two threaded holes 111.

[0039] Specifically, the card-lifting plate 200 is further provided with nuts 110, the threaded holes 111 are located in the nuts 110, and the nuts 110 are fixed to the card-lifting plate 200 by welding or other means.

[0040] Among them, the number of lead screws 300 is at least two, the lead screws 300 are rotatably connected to the base 100, each lead screw 300 is threadedly connected to each threaded hole 111, and the lead screw 300 is provided with driven wheels 310.

[0041] Among them, the synchronous drive component 400 includes a drive element and a transmission member. The drive element is connected to the base 100. A driving wheel 411 is provided on the output shaft of the drive element. Each driven wheel 310 of the lead screws 300 is connected to the driving wheel 411 through the transmission member. The drive element can drive the transmission member through the driving wheel 411 to drive each driven wheel 310 to rotate, and drive the card-lifting plate 200 to lift and lower through the rotation of the lead screw 300.

[0042] Specifically, the drive element is a motor 410.

[0043] More specifically, a circuit board 600 is further included. The drive element is electrically connected to the circuit board 600, and the circuit board 600 can control whether the drive element works or not.

[0044] As another alternative implementation, the drive element can also be a manual drive element such as a rocker.

[0045] In this implementation, the drive element can drive the transmission member through the driving wheel 411 to drive each driven wheel 310 to rotate, and drive the card-lifting plate 200 to lift and lower through the rotation of the lead screw 300. Due to the synchronization of the rotation of the lead screw 300, the forces on each position of the card-lifting plate 200 are evenly and stably distributed, thereby realizing the stable lifting and lowering of the card-lifting plate 200.

[0046] It is also worth noting here that since the lead screw transmission itself has a large transmission ratio, there is no need to design a complex reduction structure to ensure that the card-lifting plate 200 has sufficient load-bearing capacity when rising.

[0047] As Figures 1 - 4 shown, on the basis of the above implementation, the transmission member is a synchronous belt 420. The driven wheel 310 is in contact with the synchronous belt 420, and the driving wheel 411 is in contact with the synchronous belt 420.

[0048] In this implementation, the transmission member is a synchronous belt 420. The driving wheel 411 drives multiple driven wheels 310 to rotate simultaneously through the synchronous belt 420, ensuring the synchronization of the rotation of each lead screw 300.

[0049] Specifically, the synchronous belt 420 is a closed-loop structure. The synchronous belt 420 is sleeved on the driving wheel 411 and each driven wheel 310, and the driving wheel 411 and each driven wheel 310 are both located inside the synchronous belt 420.

[0050] In this embodiment, the timing belt 420 is sleeved on the driving wheel 411 and each driven wheel 310, so as to increase the contact between the timing belt 420 and the driving wheel 411 and each driven wheel 310 by tensioning, thereby ensuring the transmission efficiency among the driving wheel 411, the timing belt 420 and the driven wheel 310.

[0051] As another alternative embodiment, the timing belt 420 can also be an open-loop structure.

[0052] As Figures 1 - 4 shown, on the basis of the above embodiment, it further includes an idler pulley 500, the idler pulley 500 contacts the outer side of the timing belt 420, and the idler pulley 500 is located in the enclosed space formed between the driving wheel 411 and each driven wheel 310, so that the timing belt 420 bends towards its own interior.

[0053] In this embodiment, the idler pulley 500 is located in the enclosed space formed between the driving wheel 411 and each driven wheel 310, so that the timing belt 420 bends towards its own interior, increasing the contact area between the timing belt 420 and the driving wheel 411 or the driven wheel 310, and ensuring the transmission efficiency between the driving wheel 411 and the driven wheel 310.

[0054] It is also worth noting here that due to the function of the idler pulley 500, the timing belt 420 can avoid the position where other components are installed on the base 100.

[0055] As Figures 1 - 4 shown, on the basis of the above embodiment, the timing belt 420 is a toothed belt, the driven wheel 310 is a first gear, the driving wheel 411 is a second gear, the driven wheel 310 meshes with the timing belt 420, and the driving wheel 411 meshes with the timing belt 420.

[0056] In this embodiment, the timing belt 420 is a toothed belt, the driven wheel 310 is a first gear, the driving wheel 411 is a second gear, the driven wheel 310 meshes with the timing belt 420 and the driving wheel 411 meshes with the timing belt 420, and the transmission efficiency among the driving wheel 411, the timing belt 420 and the driven wheel 310 is ensured through toothed transmission.

[0057] Embodiment 2

[0058] The other basic structures of this embodiment (not shown in the figure) are the same as those of Embodiment 1. The difference is that the transmission member is a transmission gear set, the driven wheel 310 is a third gear, the driving wheel 411 is a fourth gear, the driven wheel 310 meshes with the transmission gear set, and the driving wheel 411 meshes with the transmission gear set.

[0059] In this embodiment, the transmission between the driven wheel 310 and the driving wheel 411 is achieved through a transmission gear set. The driving wheel 411 drives multiple driven wheels 310 to rotate simultaneously through the transmission gear set, ensuring the synchronization of the rotation of each lead screw 300.

[0060] Based on the above embodiment, the angular velocities of the respective driven wheels 310 are the same.

[0061] In this embodiment, in order to ensure the synchronization of the rotation of the lead screw 300 and the uniform and stable force at each position of the card lifting plate 200, specifically, the number of teeth of each driven wheel 310 can be set to be the same, and the diameters of each driven wheel 310 can be the same.
