[0024] The following will further describe the technical solutions of the present invention in conjunction with the drawings of the embodiments of the present invention. The present invention is not limited to the following specific implementation manners. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.
[0025] As Figures 1 to 6 shown, a marble screening and dropping device includes: a panel 100, a dropping bracket 200, a bead removing bracket 300, a height limiting mechanism, a first side plate 500, a second side plate 600, a screening mechanism, and a detection mechanism; a bead inlet 101 and a bead outlet 102 are formed on the panel 100, the dropping bracket 200 and the bead removing bracket 300 are both arranged on the panel 100, the dropping bracket 200 is located on one side of the bead inlet 101, the bead removing bracket 300 is located on one side of the bead outlet 102, the height limiting mechanism is arranged on the panel 100, and the height limiting mechanism is used to limit the bead inlet 101; the first side plate 500 and the second side plate 600 are both arranged on a surface of the panel 100 away from the dropping bracket 200 and the bead removing bracket 300, one side of the screening mechanism is connected to the first side plate 500, and the other side is connected to the second side plate 600; a part of the detection mechanism is arranged on the first side plate 500, and another part is arranged on the second side plate 600.
[0026] Specifically, the height-limiting mechanism is a height-limiting plate 400, and the height-limiting plate 400 is adhered to the panel 100. A height-limiting notch 401 is formed in the height-limiting plate 400, and the height-limiting notch 401 communicates with the bead inlet 101. That is to say, the height-limiting plate 400 is detachably adhered to the panel 100. Since the height-limiting notch 401 is formed in the height-limiting plate 400, only when the diameter is smaller than the opening formed by the overlap of the height-limiting notch 401 and the bead inlet 101 can the marbles pass through smoothly. That is to say, by adjusting the vertical position of the height-limiting plate 400 on the panel 100 according to specific requirements, the size of the overlapping opening can be adjusted, so that specific adjustment can be made according to the specific diameter of the marbles to be screened. This is not described in detail in this embodiment.
[0027] Further, two circular holes 501 are formed in the first side plate 500, and two first bolts are provided on the first side plate 500. Each first bolt passes through one of the circular holes 501 and is fixed to the panel 100. Two U-shaped holes 601 are formed in the second side plate 600, and two second bolts are provided on the second side plate 600. Each second bolt passes through one of the U-shaped holes 601 and is fixed to the panel 100. That is to say, since the two holes formed in the first side plate 500 are circular holes 501, only fixed installation can be carried out when installed on the panel 100. Since the two holes formed in the second side plate 600 are U-shaped holes 601 and the U-shaped holes 601 are horizontally formed, the position of the second side plate 600 can be adjusted according to requirements. That is to say, the distance between the first side plate 500 and the second side plate 600 can be adjusted in the horizontal direction. Therefore, when the second side plate 600 needs to be installed at the position closest to the first side plate 500, each second bolt needs to pass through the end of the U-shaped hole 601 close to the first side plate 500, and then the two second bolts are tightened. At this time, the second side plate 600 will be located at the position closest to the first side plate 500. On the contrary, when the second side plate 600 needs to be installed at the position farthest from the first side plate 500, each second bolt needs to pass through the end of the U-shaped hole 601 far from the first side plate 500, and then the two second bolts are tightened. At this time, the distance between the first side plate 500 and the second side plate 600 reaches the farthest position.
[0028] In the above embodiments, the screening mechanism includes a first track 710, a second track 720, a balance plate 730, a first support column 740, a second support column 750, a first channel 760, and a second channel 770. The first track 710 is disposed on one surface of the first side plate 500, and the second track 720 is disposed on one surface of the second side. The first track 710 and the second track 720 are correspondingly arranged. The first channel 760 is disposed on one surface of the first side plate 500, and the second channel 770 is disposed on one surface of the second side plate 600. The first channel 760 and the second channel 770 are in movable abutment. That is to say, when the first channel 760 abuts against the second channel 770, the distance between the first side plate 500 and the second side plate 600 reaches the minimum at this time, that is, the distance between the first track 710 and the second track 720 is the minimum. Further, the width of the first channel 760 is greater than that of the first track 710, and the width of the second channel 770 is greater than that of the second track 720. That is to say, when the first channel 760 abuts against the second channel 770, the first track 710 will not abut against the second track 720. And when the distance between the first track 710 and the second track 720 reaches the maximum, the distance between the first channel 760 and the second channel 770 also reaches the maximum at this time. However, the distance between the first channel 760 and the second channel 770 is less than the distance between the first track 710 and the second track 720. That is to say, the marbles falling from between the first track 710 and the second track 720 will not fall out through the gap between the two when they fall onto the first channel 760 and the second channel 770. Further, one end of the first support column 740 is connected to the balance plate 730, and the other end is rotatably disposed on one surface of the first side plate 500. One end of the second support column 750 is connected to the balance plate 730, and the other end is rotatably disposed on one surface of the second side plate 600. Further, both the first support column 740 and the second support column 750 are telescopic columns. That is to say, when the staff adjusts the distance between the first side plate 500 and the second side plate 600, it is necessary to adjust the lengths of the first support column 740 and the second support column 750 respectively, so that the balance plate 730 can be well connected between the first side plate 500 and the second side plate 600. Further, the first side plate 500 is provided with a first circular hole, and the second side plate 600 is provided with a second circular hole. One end of the first support column 740 is rotatably disposed in the first circular hole, and one end of the second support column 750 is rotatably disposed in the second circular hole. That is to say, when the first support column 740 and the second support column 750 are telescopic columns, how to adjust the length can be realized by the prior art, that is, the length can be adjusted manually, and there is a fixator for fixing the specific length. Therefore, it will not be described in detail in this embodiment.It is worth mentioning that bearings are provided in both the first round hole and the second round hole. Therefore, one end of the first support column 740 is rotatably arranged in the first round hole through the bearing, and one end of the second support column 750 is rotatably arranged in the second round hole through the bearing.
[0029] In one embodiment, a weight mechanism is provided at one end of the balance plate 730, and the weight mechanism is located at one end of the balance plate 730 close to the first channel 760 and the second channel 770. The weight mechanism includes a fixing screw 910 and an adjusting nut 920. An installation nut 731 is provided on the balance plate 730. The fixing screw 910 is connected to the installation nut 731, and the adjusting nut 920 is rotatably arranged on the fixing screw 910. That is to say, since the balance plate 730 in the initial state inclines towards the side where the weight mechanism is provided, therefore, by adjusting the position of the adjusting nut 920 on the fixing screw 910, the magnitude of a downward pressure on the entire balance plate 730 can be adjusted. That is to say, the closer the adjusting nut 920 is to the balance plate 730, the smaller the inclination angle of the balance plate 730; conversely, the larger the inclination angle of the balance plate 730, that is, the greater the downward pressure exerted on the balance plate 730 by the entire weight mechanism. It is worth mentioning that when installing this marble screening and feeding device on an external marble game machine, the position of the adjusting nut 920 needs to be adjusted according to requirements first, and then installation can be carried out. That is to say, when this parameter needs to be changed, the entire marble screening and feeding device needs to be removed from the marble game machine and then adjusted.
[0030] In the above-mentioned embodiment, the detection mechanism includes a transmitter and a receiver. The transmitter is arranged on the first side plate 500, the receiver is arranged on the second side plate 600, and the transmitter faces the receiver. Specifically, the transmitter is a light emitting eye 810, and the receiver is a light receiving eye 820. That is to say, the balance plate 730 is divided into a first area 732 and a second area 733 on average. The first area 732 is located at one end of the balance plate 730 away from the weight mechanism, and the second area 733 is located at one end of the balance plate 730 close to the weight mechanism. Specifically, the marbles that successfully pass through the first track 710 and the second track 720 all fall onto the first area 732.
[0031] That is to say, when using this marble screening and dropping device, after the staff adjusts this marble screening and dropping device, it is installed on the external marble game machine. That is, through adjustment, the specific diameter and weight of the marbles are set. It is worth mentioning that only one marble can be dropped each time. That is to say, dropping one marble can start the marble game machine. Specifically, the height-limiting plate 400 is pasted according to requirements. The height-limiting plate 400 is used to limit marbles with too large diameters from entering the inside of the dropping device, and allows marbles with diameters smaller than the limited diameter to enter the inside of the marble screening and dropping device. Since the first track 710 and the second track 720 form a passage for marbles after they enter the bead inlet 101, and there is a gap in the middle. It is worth mentioning that the size of the gap is achieved by adjusting the position of the second side plate 600. That is to say, using the distance of the gap between the first track 710 and the second track 720, if the diameter of the marble entering from the bead inlet 101 is smaller than the width of the gap, it will directly fall down and finally fall onto the bead-return passage formed by the first passage 760 and the second passage 770, and then exit from the bead-return port 102 to the bead-return bracket 300. That is to say, through this method, marbles with diameters smaller than the set diameter size can be made to fall, and marbles that meet the set diameter size slide along the first track 710 and the second track 720 to the first area 732 of the balance plate 730. It is worth mentioning that in order to detect the weight of the marbles, a weighting mechanism is set, and the weighting mechanism is located at one end of the balance plate 730, that is, on one side of the second area 733. Therefore, a downward pressure is applied to the entire balance plate 730 on one side of the second area 733. When the marble falls on the first area 732, if the weight of the marble is less than the weight of the weighting mechanism, that is, the downward pressure exerted by the marble on the balance plate 730 in the first area 732 is less than the downward pressure exerted by the weighting mechanism on the balance plate 730. At this time, the marble cannot press the balance plate 730 downward in the direction of the first area 732, and the balance plate 730 still tilts in the direction of the second area 733, causing the marble to slide along this direction and finally fall from the balance plate 730, directly falling onto the bead-return passage formed by the first passage 760 and the second passage 770, and then exiting from the bead-return port 102 to the bead-return bracket 300. If the weight of the marble is greater than the weight of the weighting mechanism, that is, the downward pressure exerted by the marble on the balance plate 730 in the first area 732 is greater than the downward pressure exerted by the weighting mechanism on the balance plate 730. At this time, the marble presses the balance plate 730 downward in the direction of the first area 732, causing the balance plate 730 to tilt towards one end of the first area 732. At this time, the marble will slide, then pass through and block the emission light eye 810 and the receiving light eye 820, and finally fall out of the marble screening and dropping device and fall into the external marble game machine. At this time, the marble game can start. That is to say, by setting the emission light eye 810 and the receiving light eye 820, it is used to detect whether the marble successfully drops out from this position, thereby ensuring that the marble does not stay in the marble screening and dropping device.
[0032] In the above embodiments, the detection mechanism further includes a light eye circuit board 830, which is disposed on one surface of the first side plate 500, and the light eye circuit board 830 is electrically connected to the transmitting light eye 810 and the receiving light eye 820. Further, the light eye circuit board 830, the transmitting light eye 810, and the receiving light eye 820 are all powered by an external power source after the entire marble screening and ball-throwing device is installed on an external marble game machine. That is to say, by providing the light eye circuit board 830, when a marble passes between the transmitting light eye 810 and the receiving light eye 820, a signal will be sent to the light eye circuit board 830, and then the light eye circuit board 830 processes this signal and conveys it to the control system of the external marble game machine, which means that it can be confirmed that the marble has fallen out of the marble screening and ball-throwing device and has officially entered the marble game machine at this time.
[0033] In summary, the above embodiments are not restrictive embodiments of the present invention. Any modification or equivalent deformation made by those skilled in the art based on the substantial content of the present invention falls within the technical scope of the present invention.
