Description

Technical Field

[0001] The utility model relates to the field of driving devices, and particularly relates to a magnetic attraction driving part of a poker card dispenser. Background Art

[0002] When the poker card machine performs the card dealing operation, the poker cards in the poker card stack are conveyed one by one in sequence, and during the conveyance of the poker cards, the hatch door of one of the several compartments located on the poker card conveyance track changes from the closed state to the open state, so that the conveyed poker cards directly fall into the compartment with the open hatch door.

[0003] The existing opening method of the hatch door on the poker card machine is mainly rotation, and generally it is driven by a push-pull electromagnet. The push-pull electromagnet mainly includes a coil and an iron core. For the sake of use safety and installation convenience, the coil is often installed in a metal shell, which not only increases the assembly difficulty of the push-pull electromagnet, but also raises the manufacturing cost. At the same time, the metal shell also increases the weight of the push-pull electromagnet, which will have a certain impact on the stability of the push-pull electromagnet installed and used in a suspended manner. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a magnetic attraction driving part of a poker card dispenser, which reduces the manufacturing difficulty while facilitating the control of the weight of the device, and ensures the stability of the driving effect of the device on the hatch door.

The two ends of the spring respectively abut against the iron core and the installation frame, and a connection hole is radially penetrated along the outer end of the iron core.

[0010] As a further improvement of the above technical solution, the installation frame includes a winding rod, and the two ends of the winding rod are integrally connected with a first retaining piece and a second retaining piece respectively. Both the first retaining piece and the second retaining piece are arranged at right angles to the winding rod. The sliding cavity is formed at one end of the winding rod, the second retaining piece is located at the other end of the winding rod, an installation piece is integrally connected to the second retaining piece and they are arranged at right angles, and a waist-shaped hole is formed on the installation piece.

[0011] As a further improvement of the above technical solution, two reinforcing sheets are provided between the second baffle and the mounting sheet. The two reinforcing sheets are symmetrically arranged left and right relative to the mounting sheet, and the kidney-shaped hole is located between the two reinforcing sheets.

[0012] As a further improvement of the above technical solution, a limiting sheet is integrally connected to the first baffle.

[0013] As a further improvement of the above technical solution, a groove for accommodating the wire to pass through is formed on the edge of the second baffle.

[0014] As a further improvement of the above technical solution, a convex block is provided on the edge of the second baffle, and two through holes for the wire to pass through are formed on the convex block.

Specific implementation mode

[0025] The present utility model will be further described in detail below in conjunction with the drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0026] See Figures 1 - 3 , the magnetic attraction driving member of the poker card dispenser in this embodiment includes a mounting bracket 1 and an iron core 2. The mounting bracket 1 is made of insulating material and a coil 3 is wound thereon. A sliding cavity 4 is axially formed on the mounting bracket 1. The inner end of the iron core 2 is slidably arranged in the sliding cavity 4 and can rotate. The central axes of the iron core 2 and the mounting bracket 1 are on the same straight line. A spring 21 for applying a force to the iron core 2 to extend out of the sliding cavity 4 is provided between the iron core 2 and the mounting bracket 1. The two ends of the spring 21 respectively abut against the iron core 2 and the mounting bracket 1. A connection hole 22 is radially penetrated along the outer end of the iron core 2. [[ID=1�]]

[0027] When power is supplied to the coil 3 on the mounting bracket 1, so that current passes through the coil 3, the magnetic field generated on the coil 3 will cause the iron core 2 to be affected by electromagnetic force and extend into the sliding cavity 4, so that the iron core 2 can pull the component connected to it through the connection hole 22, thereby realizing the effect of driving the component to perform linear movement or rotation. At this time, the spring 21 is in a compressed state, and when the power supply to the coil 3 is stopped, the iron core 2 can be reset under the restoring force of the spring 21.

[0028] In this embodiment, the diameter of the iron core 2 is smaller than the diameter of the sliding cavity 4, so that there is a gap between the iron core 2 and the sliding cavity 4, ensuring the driving effect of the magnetic field generated after the coil 3 is energized on the iron core 2.

[0029] See Figure 1 , the coil 3 is wrapped with insulating tape 31, ensuring the safety of use. When not wired, the two wiring terminals 32 of the coil 3 are both exposed on the insulating tape 31, improving the convenience of wiring. After wiring is completed, the insulating tape 31 can be used to wrap the wiring terminals 32 or the wiring terminals 32 can be pushed into the insulating tape 31 on the coil 3.

[0030] See Figure 1 、 Figure 2, the mounting bracket 1 includes a wire winding rod 11. First and second retaining pieces 12 and 13 are integrally connected to both ends of the wire winding rod 11 respectively. The first and second retaining pieces 12 and 13 are both arranged at right angles to the wire winding rod 11, ensuring the stability of the coil 3 arranged on the wire winding rod 11. A sliding cavity 4 is formed at one end of the wire winding rod 11, and the second retaining piece 13 is located at the other end of the wire winding rod 11. An installation piece 5 is integrally connected to the second retaining piece 13 and they are arranged at right angles. A waist-shaped hole 51 is formed on the installation piece 5, enabling the adjustment of the installation position of the device, thus improving the convenience of device installation while ensuring the driving effect of the device.

[0031] See Figure 1 , two reinforcing pieces 6 are provided between the second retaining piece 13 and the installation piece 5. The two reinforcing pieces 6 are symmetrically arranged left and right with respect to the installation piece 5, ensuring the structural strength between the second retaining piece 13 and the installation piece 5 and improving the stability of the structure. The waist-shaped hole 51 is located between the two reinforcing pieces 6.

[0032] See Figure 2 , a heat dissipation hole 8 is formed on the second retaining piece 13. The heat dissipation hole 8 is connected to the sliding cavity 4 and the diameter of the heat dissipation hole 8 is smaller than the diameter of the iron core 2, preventing the iron core 2 from detaching from the mounting bracket 1 under the drive of the energized coil 3 while ensuring the heat dissipation of the device.

[0033] To ensure the orderly arrangement of the wires connected to the coil 3 and reduce the risk of the wires affecting the operation of the poker card dispenser, the following two structural methods can be set on the second retaining piece 13:

[0034] (1) A groove 71 for accommodating the wire to pass through is formed on the edge of the second retaining piece 13, as shown in Figure 1 , Figure 2 ;

[0035] (2) A convex block 72 is provided on the edge of the second retaining piece 13, and two through holes 73 for the wire to pass through are formed on the convex block 72, as shown in Figure 4 .

[0036] See Figure 3 , a limiting piece 9 is integrally connected to the first retaining piece 12. When the device is installed, the device can be installed more stably by inserting the limiting piece 9 into the machine frame.

[0037] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claim book, they should fall within the protection scope of the present utility model.
