When the shuffling machine 10 performs a shuffling action, that is, the playing cards 1 are transferred from the left pocket 12 and the right pocket 13 to the central pocket 11 through the card passing wheel set 16, and the pressure The card arm 22 uses the elastic force of the return spring 221 to press the card pressing wheel 222 against the playing card 1, so that the playing card 1 and the card passing wheel 16 increase the friction, so that the rotatable card passing wheel 16 does Playing card 1 is transferred into the central slot 11, but the playing cards 1 accommodated in the left pocket 12 and the right pocket 13 are gradually reduced due to being transferred out. The total thickness of the remaining few playing cards 1 will of course become thinner, which will cause the return spring 221 to fall down. The pressing card wheel 222 can no longer have the same pressure to press the playing card 1, that is, the elastic force of the return spring 221 is weakened, so that the friction between the playing card 1 and the card passing wheel 16 is reduced, and even reset The spring 221 has lost the elastic force of pressing the playing card 1, and the card passing wheel 16 is idling and the playing card 1 cannot be driven.

When the above situation occurs, it is necessary to manually remove the obstacles. Therefore, the failure rate of the shuffler 10 is high, which affects fairness and reduces the player's interest in the game. Therefore, there is a need for improvement.

The main purpose of the present invention is to solve the above-mentioned problems, and to provide an auxiliary card pressing structure of a shuffle machine. The main technology and purpose are: a card pressing arm with a return spring is pivoted on both sides of the shuffle machine, and each pressing The other end of the card arm is respectively provided with a card pressing wheel set with magnetic wheels, and the bottom of the left and right slots in the shuffle machine is equipped with magnetic parts that can attract the magnetic wheels; thereby, the magnetic parts The magnetic wheel can be attracted to increase the pressure against a small number of playing cards, so as to increase the friction to ensure smooth transmission without idling.

According to the above-mentioned object of the present invention, there is provided an auxiliary card pressing structure for a shuffle machine, the shuffle machine is provided with at least one card passing wheel set, the outside pivot of the card passing wheel set has a card pressing arm with a return spring, and The other end of the card pressing arm is respectively provided with a card pressing wheel set, the card pressing wheel set includes at least one magnetic attraction wheel, and the card passing wheel set is provided with at least one pair of magnetic attraction members corresponding to the magnetic attraction wheel.

In an embodiment of the present invention, the magnetic attraction wheel is a magnetic substance of iron, nickel, and cobalt, and the magnetic attraction member is a magnet.

With the above, when there are less playing cards in the left or right pocket, the magnetic attraction The piece can attract the magnetic wheel to increase the force of the pressing wheel set against the playing cards, and achieve the practical effect of increasing friction to ensure smooth transmission without idling.

In order for your reviewer to have a better understanding of this creation, here is a preferred embodiment combined with the diagrams. The details are as follows: Please refer to Figures 2 to 3, an auxiliary deck structure of a shuffle machine, the shuffle The machine 30 is equipped with a central container 31, a left container 32 and a right container 33. The bottom of the left container 32 and the right container 33 are respectively provided with a pass wheel 36, and the central container 31 is provided with a central lift Table 37, each of the left container 32 and the right container 33 is provided with a lifting platform 38; the outer side of the left container 32 and the right container 33 are respectively pivoted with a card pressing arm 60 with a return spring 61, each The other end of the card pressing arm 60 is respectively provided with a card pressing wheel group 62, each of the card pressing wheel groups 62 includes at least one magnetic attraction wheel 63, and each of the card passing wheel groups 36 is provided with at least one pair of magnetic attraction wheels 63 corresponding to the magnetic attraction wheels 63 64; thereby, when the left pocket 32 or the right pocket 33 has less playing cards 1, the magnetic member 64 can attract the magnetic wheel 63 to increase the pressing wheel 62 against the playing card 1 Strength, achieve the practical effect of increasing friction to ensure smooth transmission without idling.

The composition and function of the present invention are described in detail as follows: Please refer to the 2 to 3, the magnetic attraction wheel 63 of the card pressing wheel set 62 of the present invention is a magnetic substance, such as iron, nickel, cobalt and other metals, and the card pass wheel The magnetic attraction member 64 of the group 36 can be a magnet, and can attract the magnetic attraction within the magnetic field of the magnetic attraction member 64 Round 63. The magnetic member 64 of the card passing wheel 36 is set lower than the top edge of the card passing wheel 36, so that when the number of playing cards 1 is small, the magnetic member 64 can interact with the magnetic wheel 63. At this time, the return spring 61 is in a state of weak or even no elastic force. The magnetic force of the magnetic attraction member 64 provides the card pressing arm 60 to assist in pressing the playing card 1 to solve the problem. The problem that the return spring 61 cannot reliably press against the playing card 1 when the number of playing cards 1 is small. When the playing card 1 has been allocated and moved to the lifting platform 38 of the left container 32 and the right container 33 to be shuffled, each of the lifting platforms 38 is lowered to be located in the left container 32 and the right container 33 respectively. The bottom of the playing card 1 abuts the card passing wheel 36, and then each of the card pressing arms 60 can pivot from the outside to the inside due to the lowering of the lifting platforms 38, so that the card pressing wheel 62 presses against the playing cards 1 respectively , So that the playing card 1 has proper pressure against the card passing wheel 36, that is, the appropriate friction force is generated between the playing card 1 and the card passing wheel 36, so that each of the card passing wheel 36 Respectively rotate to the center of the shuffler 30, and use friction to transfer the bottommost playing cards 1 on both sides to the central lifting platform 37 of the central container 31 one by one to perform the shuffling operation of random number collection; When the left pocket 32 and the right pocket 33 have a small number of playing cards 1, the return spring 61 makes the card pressing arm 60 generate less elastic force than the initial number of playing cards 1, even the shuffler 30 After a long period of use, the return spring 61 is elastically fatigued, that is, although the left pocket 32 and the right pocket 33 still have playing cards 1, the return spring 61 has lost its elastic force against the playing card 1; As the card pressing wheel 62 of the card pressing arm 60 gradually approaches the magnetic member 64 as the number of playing cards 1 decreases, and the magnetic force of the magnetic member 64 is different, a different range of magnetic fields can be generated. Therefore, a suitable magnetic magnetic attraction can be selected. When the number of playing cards 14 decreases and the magnetic field of the magnetic attraction member 64 is used, the magnetic attraction member 64 attracts the magnetic wheel 63 to increase the pressing force of the card pressing wheel 62 The strength of playing cards 1. The smaller the number of playing cards 1, the weaker the elastic force of the return spring 61. Conversely, the stronger the attraction force of the magnetic attraction member 64 to the magnetic attraction wheel 63, thereby assisting the card pressing arm 60 Maintain a proper pressure channel for fewer playing cards 1 so that the playing cards 1 can be reliably transferred by the card passing wheel 36 to the central lifting platform 37 of the central container 31 to increase friction and ensure smooth transfer without idling. The practical effect.
