Technical Field
[0001] The utility model relates to the technical field of playing card machines, in particular to a playing card dealing machine. Background Art
[0002] Playing cards and other recreational activities have become a common pastime in people's leisure time. To simplify the tedious process of traditional manual card dealing and add a touch of entertainment, automatic card dealing machines have emerged. Their efficient automatic dealing function has greatly enhanced the experience and enjoyment of card games. However, existing card dealing machines often produce significant noise during the operation of the card pressing wheel and bracket. This not only affects the player's gaming environment but can also negatively impact the overall service life of the card dealing machine. Long-term use can further increase the wear of these components, shortening the equipment's service life. Utility Model Content
[0003] In order to overcome the deficiencies in the prior art, the utility model provides a poker card dealing machine, which has the advantage of being able to reduce shock when a card pressing shaft reciprocates relative to a card ejecting bracket.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A poker card dealing machine includes a shell, the shell is provided with a card ejecting bracket, a card pressing shaft and a supporting roller, the card pressing shaft is provided with a card pressing wheel, the supporting roller is provided with a supporting wheel, the card pressing shaft reciprocates relative to the card ejecting bracket to make the card pressing wheel approach or move away from the supporting wheel, a shock absorber and a pre-tightening member are provided between the card pressing shaft and the card ejecting bracket, the shock absorber provides buffering during the reciprocating motion of the card pressing shaft, and the pre-tightening member is pre-tightened between the card pressing shaft and the card ejecting bracket to keep the card pressing wheel pressing toward the support wheel.
[0006] The aforementioned technical solution is adopted, by pre-tightening a pre-tightening member between the card-pressing shaft and the card-ejecting bracket, so as to maintain the tendency of the card-pressing wheel to press against the support wheel. When playing cards pass through, the card-pressing wheel on the card-pressing shaft cooperates with the support wheel on the supporting roller, so that the card-pressing shaft can reciprocate and move closer to or away from the support wheel. The shock-absorbing member is arranged between the card-pressing shaft and the card-ejecting bracket, so as to provide a buffer during the reciprocating movement of the card-pressing shaft. When the card-pressing wheel approaches the support wheel under the elastic force of the pre-tightening member, the shock-absorbing member can absorb and disperse the impact force of the collision between the card-pressing shaft and the card-ejecting bracket, reducing the vibration between the mechanical components, thereby protecting the service life of the equipment and reducing the noise level.
[0007] Furthermore, the pre-tightening force provided by the pre-tightening member acts on the end of the card pressing shaft, and the shock-absorbing member is sleeved on the card pressing shaft.
[0008] By adopting the above-mentioned technical solution, the shock absorber is installed on the card pressing shaft, so that the shock absorber can directly absorb the vibration of the card pressing shaft during reciprocating motion, further reducing noise. The pre-tightening part is set at the end of the card pressing shaft to ensure balanced force.
[0009] Furthermore, the shock absorbing member is sleeved on the card pressing shaft, and the pre-tightening member is connected to the shock absorbing member.
[0010] By adopting the above-mentioned technical solution, the shock absorber is installed on the card pressing shaft, so that the shock absorber can directly absorb the vibration of the card pressing shaft during reciprocating motion, further reducing noise. The pre-tightening part is connected to the shock absorber, and pressure is indirectly applied to the card pressing shaft through the shock absorber, making the pre-tightening force more uniform and stable, and avoiding the cumbersome process caused by separate assembly of the two.
[0011] Furthermore, the pre-tightening member is provided with a first cavity for increasing the elastic coefficient.
[0012] Using the above-mentioned technical solution, the pre-tightening member is mainly used to provide continuous elastic force to ensure that the card pressing wheel can maintain a certain pressure on the support wheel. If the elastic force is too large, it will increase mechanical wear. The addition of the first cavity forms a "spring" effect inside the pre-tightening member, thereby enhancing its elastic coefficient.
[0013] Furthermore, the shock-absorbing component is provided with a second cavity for inserting the card pressing shaft.
[0014] By adopting the above-mentioned technical solution, the second cavity allows the shock-absorbing component to be easily inserted into the card pressing shaft, which simplifies the assembly process and is also convenient for disassembly and maintenance when necessary.
[0015] Furthermore, at least one end of the first cavity is open, and the cross-sectional shape and size of the first cavity and the second cavity are consistent.
[0016] By adopting the above-mentioned technical solution, at least one end of the first cavity is open, which is used to insert the shock-absorbing part into the card pressing shaft. Since the cross-sectional shape and size of the first cavity and the second cavity are consistent, the same mold can be used to manufacture these two components during the production process, thereby simplifying the production process and improving production efficiency.
[0017] Furthermore, the first cavity is provided with a connecting rib connected to the inner wall of the first cavity, and the cross section of the connecting rib is "Y"-shaped, straight-shaped, or cross-shaped.
[0018] By adopting the above-mentioned technical solution, by adding connecting ribs connected to the inner wall of the first cavity in the first cavity, the elastic coefficient can be reduced, and the elastic force can be appropriately increased. The connecting ribs can also serve as a supporting structure inside the first cavity, which can effectively prolong the time for the first cavity to deform when it is in a working state for a long time, thereby ensuring the shape and dimensional accuracy of the preloaded component during long-term use, and improving the overall strength and durability. By selecting connecting ribs of different shapes, the elastic coefficient of the preloaded component can be flexibly adjusted according to needs.
[0019] Furthermore, the card ejecting bracket includes a slideway for allowing the shock absorbing member to reciprocate.
[0020] By adopting the above-mentioned technical solution, a slideway for the reciprocating movement of the shock absorber is set in the card ejection bracket, so that the shock absorber can reciprocate along a predetermined path, thereby improving the stability of the shock absorber movement and avoiding card dealing failures caused by deviation of the shock absorber movement trajectory.
[0021] Furthermore, guide surfaces for guiding the card pressing shaft to move back and forth are provided on both sides of the pre-tightening member and / or the shock absorbing member, and the guide surfaces move along the inner wall of the slideway.
[0022] By adopting the above-mentioned technical solution, guide surfaces are provided on both sides of the preload member and / or the shock-absorbing member to guide the reciprocating motion of the card pressing shaft. The guiding effect of the guide surface ensures the high precision of the card pressing shaft during the reciprocating motion, helps to reduce the inaccurate card dealing or malfunction problems caused by the deviation of the motion trajectory, and improves the overall performance and reliability of the equipment.
[0023] Furthermore, the shock absorbing component and the pre-tightening component are integrally formed.
[0024] By adopting the above-mentioned technical solution, the shock-absorbing component and the pre-tightening component are integrally formed so that the two components become a whole during the manufacturing process. Since there is no assembly interface between the two components, structural instability caused by loose interfaces is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0036] like Figure 1 and Figure 2 As shown, a poker card dealing machine includes a shell 1, which is provided with a card ejecting bracket 11, a card pressing shaft 12 and a supporting roller 13. The card pressing shaft 12 is provided with a card pressing wheel 121, and the supporting roller 13 is provided with a supporting wheel 131. The card pressing shaft 12 reciprocates relative to the card ejecting bracket 11 to make the card pressing wheel 121 approach or move away from the supporting wheel 131. A shock absorber 122 and a pre-tightening member 123 are provided between the card pressing shaft 12 and the card ejecting bracket 11. The shock absorber 122 provides buffering during the reciprocating motion of the card pressing shaft 12, and the pre-tightening member 123 is pre-tightened between the card pressing shaft 12 and the card ejecting bracket 11 to keep the card pressing wheel 121 pressing toward the supporting wheel 131.
[0037] It is understandable that the pre-tightening member 123 is pre-tightened between the card pressing shaft 12 and the card ejecting bracket 11 to maintain the tendency of the card pressing wheel 121 to press against the support wheel 131. When playing cards pass by, the card pressing wheel 121 on the card pressing shaft 12 cooperates with the support wheel 131 on the support roller 13, so that the card pressing shaft 12 can reciprocate and move closer to or away from the support wheel 131. The shock absorber 122 is arranged between the card pressing shaft 12 and the card ejecting bracket 11, so as to provide a buffer during the reciprocating movement of the card pressing shaft 12. When the card pressing wheel 121 is moved closer to the support wheel 131 by the elastic force of the pre-tightening member 123, the shock absorber 122 can absorb and disperse the impact force of the collision between the card pressing shaft 12 and the card ejecting bracket 11, thereby reducing the vibration between the mechanical components, thereby protecting the service life of the equipment and reducing the noise level.
[0038] In one embodiment, Figure 10 As shown, the card ejecting bracket 11 includes a slide 111 for the shock absorber 122 to reciprocate. By arranging a slide 111 for the shock absorber 122 to reciprocate in the card ejecting bracket 11, the shock absorber 122 can reciprocate along a predetermined path, thereby improving the stability of the movement of the shock absorber 122 and avoiding the card dealing failure caused by the deviation of the movement trajectory of the shock absorber 122. The pre-tightening force provided by the pre-tightening member 123 acts on the end of the card pressing shaft 12, and the shock absorber 122 is sleeved on the card pressing shaft 12. The pre-tightening member 123 and the shock absorber 122 are separately arranged and are respectively placed at both ends of the card pressing shaft 12 in sequence. The shock absorber 122 is sleeved on the card pressing shaft 12 so that the shock absorber 122 can directly absorb the vibration of the card pressing shaft 12 in the reciprocating motion, thereby further reducing noise. The pre-tightening member 123 is arranged at the end of the card pressing shaft 12 to ensure balanced force.
[0039] In another embodiment, Figure 8 As shown, the card ejecting bracket 11 includes a cavity 112 for the reciprocating motion of the shock absorber 122, the shock absorber 122 is sleeved on the card pressing shaft 12, and the pre-tightening member 123 is connected to the shock absorber 122. The shock absorber 122 is sleeved on the card pressing shaft 12 so that the shock absorber 122 can directly absorb the vibration of the card pressing shaft 12 during the reciprocating motion, thereby further reducing the noise. The pre-tightening member 123 is connected to the shock absorber 122, and indirectly applies pressure to the card pressing shaft 12 through the shock absorber 122, so that the pre-tightening force is more uniform and stable, and avoids the cumbersome process caused by the separate assembly of the two.
[0040] It can be understood that by providing a cavity 112 in the card ejection bracket 11 for the reciprocating motion of the shock absorber 122, the shock absorber 122 can reciprocate along a predetermined path, thereby improving the stability of the movement of the shock absorber 122 and avoiding card dealing failures caused by deviation of the movement trajectory of the shock absorber 122.
[0041] In this embodiment, since the pre-tightening member 123 is connected to the shock absorber 122, the pre-tightening member 123 and the shock absorber 122 can be placed in the cavity 112 at the same time. The cavity 112 can serve as a slide for the reciprocating motion of the shock absorber 122, and at the same time, the axial movement of the shock absorber 122 and the pre-tightening member 123 can be avoided. The side wall of the cavity 112 is provided with an avoidance hole 113 for the card pressing shaft 12 to pass through. The aperture of the avoidance hole 113 is larger than the outer diameter of the card pressing shaft 12, so as not to interfere with the reciprocating motion of the card pressing shaft 12.
[0042] On the basis of the above embodiment, a card ejection mechanism is composed of an upper metal roller and a lower silicone roller card pressing shaft and a supporting roller, wherein the card pressing wheel placed on the card pressing shaft is a metal roller, and the supporting wheel placed on the supporting roller is a silicone roller. The card pressing wheel is fixed to the card pressing shaft, and the two ends of the supporting roller are pre-tightened with pre-tightening parts. A silicone soft sleeve is placed on the supporting roller, and the silicone soft sleeve contacts the card ejection bracket to avoid collision between the metal card pressing wheel and the card ejection bracket when it moves up and down, thereby reducing noise. The supporting roller is connected to the motor to provide power for continuous rotation. An interference pre-pressure of 0.5-1.5m is preset between the card pressing wheel and the support wheel, thereby compacting and driving the playing cards to move. The pre-pressure interference amount will also provide a certain ejection force to the playing cards when they leave, thereby increasing the initial velocity and ensuring that the ejection distance of the playing cards is within a limited range.
[0043] In one embodiment, guide surfaces 127 for guiding the reciprocating motion of the card pressing shaft 12 are provided on both sides of the pre-tightening member 123 and the shock absorbing member 122 , and the guide surfaces 127 move along the inner wall of the cavity 112 .
[0044] In another embodiment, guide surfaces 127 for guiding the card pressing shaft 12 to reciprocate are provided on both sides of the pre-tightening member 123 , and the guide surfaces 127 move along the inner wall of the cavity 112 .
[0045] In another embodiment, guide surfaces 127 for guiding the card pressing shaft 12 to reciprocate are provided on both sides of the shock absorber 122 , and the guide surfaces 127 move along the inner wall of the cavity 112 .
[0046] In the above embodiment, the guiding effect of the guide surface 127 ensures the high precision of the card pressing shaft 12 during the reciprocating motion, helps to reduce the inaccurate card dealing or malfunction problems caused by the deviation of the motion trajectory, and improves the overall performance and reliability of the equipment.
[0047] In another embodiment, the shock absorbing member 122 may also be disposed on the card ejecting bracket 11 .
[0048] The pre-tightening member 123 is provided with a first cavity 124 for increasing the elastic coefficient, which is mainly used to provide continuous elastic force to ensure that the card pressing wheel 121 can maintain a certain pressure on the support wheel 131. If the elastic force is too large, it will increase mechanical wear. The addition of the first cavity 124 forms a "spring" effect inside the pre-tightening member 123, thereby enhancing its elastic coefficient.
[0049] Optional, such as Figure 2 、 Figure 3 and Figure 4 The shape of the first cavity 124 can be set to be oval, circular or triangular according to different usage requirements.
[0050] The shock absorbing member 122 is provided with a second cavity 125 for inserting the card pressing shaft 12, so that the shock absorbing member 122 can be easily inserted into the card pressing shaft 12, simplifying the assembly process. At the same time, it is also convenient for disassembly and maintenance when necessary.
[0051] In one embodiment, one end of the first cavity 124 is open, and the cross-sectional shape and size of the first cavity 124 and the second cavity 125 are consistent.
[0052] In another embodiment, Figure 1 and Figure 3 As shown, both ends of the first cavity 124 and the second cavity 125 are connected to the outside to form through holes, and the cross-sectional shapes and sizes of the first cavity 124 and the second cavity 125 are consistent.
[0053] It can be understood that, whether one end is open or a through hole is formed, it is mainly used to insert the shock absorber 122 into the card pressing shaft 12. Since the cross-sectional shape and size of the first cavity 124 and the second cavity 125 are consistent, the same mold can be used to manufacture these two components during the production process, thereby simplifying the production process and improving production efficiency.
[0054] In another embodiment, Figure 5 As shown, the first cavity 124 is provided with a connecting rib 126 connected to the inner wall of the first cavity 124 , and the cross section of the connecting rib 126 is Y-shaped, straight-shaped, or cross-shaped.
[0055] It is understood that by adding a connecting rib 126 connected to the inner wall of the first cavity 124 within the first cavity 124 to reduce its elastic coefficient, the elastic force can be appropriately increased. The connecting rib 126 can also serve as a supporting structure within the first cavity 124, effectively extending the time it takes for the first cavity 124 to deform when in operation for a long time, ensuring the shape and dimensional accuracy of the preload member 123 during long-term use, and improving the overall strength and durability. By selecting different shapes of the connecting rib 126, the elastic coefficient of the preload member 123 can be flexibly adjusted according to needs.
[0056] like Figure 6 and Figure 7 As shown, the playing card dealing machine also includes a base 2 and a motor 3. The motor 3 is installed on the card ejecting bracket 11, and the card ejecting bracket 11 is fixedly installed on the base 2. The card pressing shaft 12 is placed above the supporting roller 13, and the motor 3 is placed above the card pressing shaft 12. The motor 3 drives the supporting roller 13 to rotate through the first transmission assembly 4. The supporting roller 13 is provided with a supporting wheel 131, and the supporting wheel 131 rotates together with the supporting roller 13. The card pressing wheel 121 on the card pressing shaft 12 is driven to rotate by the supporting wheel 131, and the card pressing shaft 12 reciprocates relative to the card ejecting bracket 11. When a playing card passes between the support wheel 131 and the card pressing wheel 121, the card pressing wheel 121 moves away from the support wheel 131. When no playing card passes between the support wheel 131 and the card pressing wheel 121, the card pressing wheel 121 approaches the support wheel 131, and the playing card is ejected through the rotation connection between the support wheel 131 and the card pressing wheel 121. The shell 1 is provided with a playing card ejection outlet 14 at a position opposite to it.
[0057] Optionally, the card ejection bracket 11 can be fixed on the base 2 by bolts or by gluing; the shell 1 can also be connected by the cooperation between bolts and screw holes or by positioning structures and positioning holes or snap connections.
[0058] Preferably, the shock absorbing member 122 and the pre-tightening member 123 are both made of silicone or latex, and the shock absorbing member 122 and the pre-tightening member 123 are integrally formed.
[0059] It can be understood that the shock-absorbing member 122 and the pre-tightening member 123 are made of the same material and the one-piece molded structure is more stable. Silicone and latex are both materials with good elasticity and shock-absorbing properties. They can deform when subjected to external forces and effectively absorb and disperse impact forces, thereby reducing vibration and impact between mechanical parts. At the same time, they are not easy to wear, age or deform, thereby extending the service life of the equipment and reducing maintenance costs.
[0060] In another embodiment, the shock absorbing member 122 is made of silicone material, and the pre-tightening member 123 is a metal elastic member.
[0061] It can be understood that the silicone shock absorber 122 can effectively absorb vibrations and impacts between mechanical parts, protect the equipment from damage, and reduce noise. The metal elastic preload member 123 has high strength, can maintain a stable shape when under pressure, and can quickly return to its original shape when subjected to external force, providing continuous elastic force to ensure that the card pressing wheel 121 maintains appropriate pressure during operation.
[0062] Optionally, the metal elastic member may be a spring or an elastic sheet.
[0063] In this embodiment, if Figure 6 and 9 As shown, a card transmission component 5 and an output shaft 6 for transmitting the card transmission component 5 are also provided in the shell 1. The card transmission component 5 and the support roller 13 are both driven by the motor 3. The motor 3 drives the support roller 13 to rotate through the first transmission component 4. The first transmission component includes: a first synchronous wheel 41 arranged on one side of the motor 3, and a second synchronous wheel 132 arranged at one end of the support roller 13. The first synchronous wheel 41 and the second synchronous wheel 132 are connected by a synchronous belt 42. The other end of the support roller is provided with a third synchronous wheel. One end of the output shaft 6 is provided with a transmission wheel 61 connected to the support roller. A first output wheel 62 coaxially arranged with the transmission wheel 61 is also provided on the outside of the transmission wheel 61. The other end of the output shaft 6 is provided with a second output wheel 63 having the same transmission ratio as the first output wheel 62. The first output wheel 62 and the second output wheel 63 are synchronously transmitted with the card transmission component 5 on both sides.
[0064] In another embodiment, a first motor 3 is provided to directly drive the card transfer assembly 5 , and a second motor 3 is provided to directly drive the support roller 13 .
