The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0027] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0028] Reference Figures 1 to 4 As shown, a bead dispenser for a gaming machine includes a panel 1 and a screening box 2. The panel 1 is provided with a bead insertion port 11 and a bead withdrawal port 12. The screening box 2 is fixed to the panel 1 for connecting the bead insertion port 11 and the bead withdrawal port 12. The screening box 2 is provided with a first screening channel 21, a second screening channel 22, a partition plate 3, a bead withdrawal ramp 4, and a bead inlet channel 5. The first screening channel 21 is connected to the bead insertion port 11 and is inclined downward in a direction away from the bead insertion port 11. The bead withdrawal ramp 4 is located below the first screening channel 21. The upper end of the bead withdrawal ramp 4 is connected to the lower end of the first screening channel 21, and the lower end of the bead withdrawal ramp 4 is connected to the bead withdrawal port 12.

[0029] The second screening channel 22 is lower than the first screening channel 21. The second screening channel 22 is inclined downward in a direction away from the first screening channel 21. The lower end of the second screening channel 22 is connected to the bead inlet channel 5. The partition plate 3 is located above the second screening channel 22. There is a gap between the partition plate 3 and the first screening channel 21. The partition plate 3 blocks the materials that have not passed through the first screening channel 21 and drops them onto the second screening channel 22.

[0030] During use, materials are put into the bead-feeding port 11 and will be screened for the first time on the first screening channel 21. If they are screws or small-sized marbles, they will pass through the first screening channel 21 and fall onto the bead-returning ramp 4 and be discharged from the bead-returning port 12. If the material speed is too fast and is not screened on the first screening channel 21, it will be blocked by the partition plate 3 and screened again on the second screening channel 22. Below the second screening channel 22 is generally a waste bin set inside the game machine, which has double screening guarantees to ensure that screws and marbles that do not meet the size can be screened out, and only compliant marbles can enter the bead-feeding channel 5.

[0031] In this embodiment, the bead-retracting ramp 4 can be a straight ramp or a continuously curved ramp, and can be arranged according to actual needs.

[0032] In this embodiment, the screening box body 2 includes two side panels 23 arranged on the left and right. Generally speaking, the two side panels 23 are arranged symmetrically. A bead throwing bracket 13 and a bead returning bracket 14 are provided on one side of the panel 1. The side panel 23 is provided on the side of the panel 1 facing away from the bead throwing bracket 13.

[0033] The two side panels 23 are first fixed together by screws and then fixed to the panel 1;

[0034] The panel 1 is provided with a first positioning groove 15 and a second positioning groove 16. The end of the bead-injecting bracket 13 close to the panel 1 is embedded in the first positioning groove 15, and the end of the bead-returning bracket 14 close to the panel 1 is embedded in the second positioning groove 16. The positions of the bead-injecting bracket 13 and the bead-returning bracket 14 can be accurately controlled.

[0035] The bead throwing bracket 13 and the bead returning bracket 14 can be fixed to the panel 1 by means of snap fastening or by means of screw fastening.

[0036] In this embodiment, a first ridge 6 is provided on the side panel 23. A first screening channel 21 is formed between the first ridges 6 on the two side panels 23. The first ridge 6 and the side panel 23 are an integral injection-molded structure. This structure ensures better precision and makes it easier to control the spacing between the two first ridges 6, thereby ensuring a screening effect.

[0037] At the same time, a first groove 24 is provided on the side of the side panel 23 facing away from the first ridge 6. The first groove 24 corresponds to the first ridge 6. The depth of the first groove 24 is greater than the thickness of the side panel 23. The first groove 24 can be recessed into the first ridge 6. The first groove 24 is also integrally formed during injection molding. The presence of the first groove 24 can improve the strength of the first ridge 6.

[0038] Similarly, a second ridge 7 is provided on the side panel 23, and a second screening channel 22 is constructed between the second ridges 7 on the two side panels 23. The second ridge 7 and the side panel 23 are an integral injection-molded structure. A second groove 25 is provided on the side of the side panel 23 facing away from the second ridge 7. The second groove 25 corresponds to the second ridge 7. The depth of the second groove 25 is greater than the thickness of the side panel 23. The spacing between the two second ridges 7 is better guaranteed, and the strength of the second ridge 7 is better.

[0039] In this embodiment, a first baffle 8 is provided above the first screening channel 21, and the first baffle 8 is rotatably connected to the screening box body 2. The first baffle 8 is used to delay the time for the material to pass over the first screening channel 21; after the material is put into the bead-dropping port 11, if it does not pass through the first screening channel 21 in the first time, it will move along the first ridge 6 and gradually slide down, and the first baffle 8 can hinder the movement of the material to prevent the material from moving too fast. The material may adjust its direction when moving slowly, thereby passing through the first screening channel 21. Moreover, the setting of the first baffle 8 requires that the material must have a certain weight before the material can push the first baffle 8 open. Therefore, if the marbles meet the specifications, the marbles will move along the first ridge 6 and push the first baffle 8 to rotate.

[0040] In this embodiment, a limiting plate 9 is provided on the side of the partition plate 3 close to the first screening channel 21. The upper end of the limiting plate 9 is rotatably connected to the screening box body 2. The lower end of the limiting plate 9 facing away from the first screening channel 21 is provided with a limiting protrusion 91. The limiting protrusion 91 is used to press against the partition plate 3.

[0041] If the material is not screened out on the first screening channel 21, it will move to between the first ridge 6 and the limit plate 9. The distance between the first ridge 6 and the limit plate 9 is designed so that only marbles and materials that meet the specifications or are smaller can pass through. Slightly larger marbles will get stuck and rely on manual troubleshooting. After the material passes between the first ridge 6 and the limit plate 9, it falls onto the second screening channel 22 for secondary screening.

[0042] The rotatable design of the limit plate 9 makes it easier for staff to troubleshoot.

[0043] In this embodiment, a second baffle 10 is provided above the second screening channel 22. The second baffle 10 is rotatably connected to the screening box 2. The second baffle 10 is used to delay the time for the material to pass over the second screening channel 22.

[0044] If the material is not screened out by the second screening channel 22, the material will move along the second ridge 7. The second baffle 10 can hinder the movement of the material to prevent the material from moving too fast. The material may adjust its position when moving slowly for screening. If the marbles meet the specifications, the marbles will move along the second ridge 7 and push open the second baffle 10. Then the marbles can enter the bead input channel 5, that is, enter the inside of the game machine.

[0045] In this embodiment, a photoelectric sensor is provided on the screening box 2 to detect whether a marble has passed through the bead inlet passage 5. Specifically, a transmitter is provided on one side panel 23, and a receiver is provided on the other side panel 23. A hole 26 is provided in each side panel 23. The transmitter transmits light through hole 26, and the receiver receives light through hole 26. If the receiver does not receive light, it is determined that a marble has passed through the bead inlet passage 5.

[0046] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
