Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal coin vending machine technology, and in particular to a fully automatic silver coin color printing and vending device. Background Technology
[0002] Customized silver coin designs are becoming increasingly popular. Users can input their preferred designs into the vending machine, which will then print or engrave the design onto the coin and deliver it to the user in its small packaging box. Currently, most silver coin vending machines on the market use laser engraving to imprint customized designs onto the coin surface. This method produces relatively rough designs, only lines without color, making them less aesthetically pleasing and failing to attract those who prioritize aesthetics. Some vending machines use colored ink, but existing machines generally use a single-channel coin supply, resulting in low storage capacity, limited coin types, and low automation. They require multiple manual coin insertions and retrievals, leading to inconvenience and frequent coin jams. Furthermore, the inability to promptly shut off power after a jam can cause further malfunctions and high maintenance costs. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fully automatic silver coin color printing and vending device.
[0004] To achieve the above objectives, a fully automatic silver coin color printing and vending device includes a chassis. The chassis houses a multi-channel conveying mechanism, a color printing mechanism, and a receiving mechanism. The output end of the multi-channel conveying mechanism corresponds to the input end of the color printing mechanism, and the output end of the color printing mechanism corresponds to the input end of the receiving mechanism. The multi-channel conveying mechanism includes a conveying support and multiple coin storage channels arranged side-by-side and vertically on the conveying support. A conveying channel is horizontally arranged on the conveying support, connecting to the output end of the coin storage channel. A conveying block is installed within each conveying channel.

The multi-channel conveying mechanism 3 stores silver coins and conveys them to the color printing mechanism 4 for color printing as needed. The output end of the color printing mechanism 4 corresponds to the input end of the receiving mechanism 5. After the color printing mechanism 4 finishes its work, it conveys the silver coins to the receiving mechanism 5 for receiving and retrieval.
[0040] The multi-channel conveying mechanism 3 includes a conveying support 6 and multiple coin storage channels 7 arranged side-by-side and vertically on the conveying support 6. Each coin storage channel 7 can hold one type of silver coin, and multiple channels can accommodate multiple types of silver coins. Users can select any channel's silver coins for color printing according to their needs. A coin outlet is provided at the lower end of each coin storage channel 7. The height of the coin outlet is limited to allow only one silver coin to pass through at a time. Specifically, the height of the coin outlet restricts the packaging box, with different types of silver coins placed individually in the packaging box. The coin outlet can push out one packaging box at a time. The coin outlet can be implemented using any existing technology, which will not be elaborated here.
[0041] The conveying support 6 is horizontally provided with a conveying channel 8 that connects to the output end of the coin storage channel 7. A conveying block 9 is provided inside the conveying channel 8. A coin pushing component 10 is provided at the lower end of the coin storage channel 7. One coin pushing component 10 corresponds to the lower end of each coin storage channel 7. The coin pushing component 10 includes a push block 11 that can pass through the coin outlet and a first linear module 12 that drives the push block 11 to move back and forth longitudinally. The first linear module 12 drives the push block 11 to push the bottom silver coin into the conveying channel 8. The first linear module 12 is provided with a first slider 13 that is fixedly connected to the push block 11. Rolling elements 14 that reduce the friction of the push block 11 are provided on both sides of the push block 11. The rolling elements 14 are rollers or bearings. A pushing slope 15 is provided on the top surface of the front end of the push block 11. The push block 11 pushes the silver coin through the front end. The pushing slope 15 makes it easy for the push block 11 to cut into the bottom second to last silver coin and push it upward. The coin pusher assembly 10 also includes a first sensor 16 disposed at the front end and rear end of the travel path of the first slider 13. Any existing sensing element corresponding to the first sensor 16 can be disposed on the first slider 13 for precise control of the stroke of the pusher block 11. The first sensor 16 is electrically connected to the control center 2 and is centrally controlled by the control center 2.
[0042] The conveying support 6 is also equipped with a transmission assembly 17 that drives the conveying block 6 to convey the coins. The transmission assembly 17 includes a second linear module 18 arranged laterally and a transmission frame 19. The second linear module 18 is provided with a second slider 20 and is fixedly connected to the transmission frame 19. The transmission frame 19 is fixedly connected to the conveying block 9. The second linear module 18 drives the conveying block 9 to convey the silver coins to the color printing mechanism 4 for color printing. A guide rod 21 is provided at the rear end of the conveying block 9 in the conveying direction. A slidable inertial block 22 is provided on the guide rod 21. A spring is also sleeved on the guide rod 21 between the inertial block 22 and the conveying block 9. A contact switch 23 is provided on the transmission frame 19 near the inertial block 22. The contact switch 23 is electrically connected to the control center 2. When a coin jam occurs, the conveying block 9 suddenly stops moving, and the inertial block 22 continues to move forward due to inertia. The spring acts as a buffer at this time. After being buffered by the spring, the inertial block 22 slightly impacts the contact switch 23. The contact switch 23 transmits a signal to the control center 2 for processing. The spring can be implemented using any existing technology, which is not shown in the figure and will not be described in detail here. The transmission component 17 also includes a second sensor 24 disposed at the front and rear ends of the travel path of the second slider 20. Any existing sensing element corresponding to the second sensor 24 can be disposed on the second slider 20 for precise control of the stroke of the conveying block 9. The second sensor 24 is electrically connected to the control center 2 and is centrally controlled by the control center 2.
[0043] The output end of the conveying channel 8 is provided with a guide component 25. The guide component 25 includes a guide block 26 disposed at the end of the conveying channel 8.

The elastic balls 27 can be implemented using any existing technology, such as setting an elastic element and installing balls at the end of the elastic element. A guide ramp 28 that contracts inwards into the conveying channel 8 is disposed on one side of the guide block 26. The guide ramp 28 limits the width of the silver coin output at the end of the conveying channel 8 and guides the silver coin to a predetermined position. The elastic balls 27 can press the silver coin, automatically calibrating it and preventing misalignment that could cause jamming. The elastic balls 27 are partially distributed on the guide ramp 28.
[0044] The color printing mechanism 4 includes a color printing base 29 and a UV color printing component 30, a slide assembly 31, and a lifting ink stack 32 disposed on the color printing base 29. The slide assembly 31 includes a printing platform 33 and a horizontally arranged third linear module 34. The third linear module 34 is provided with a third slider 35 and is fixedly connected to the printing platform 33. The third linear module 34 can drive the printing platform 33 to extend towards the conveying channel 8, so that the conveying block 9 can push the silver coin onto the printing platform 33. The printing platform 33 is provided with multiple air holes 36. The air holes 36 can be connected to any existing suction device to adsorb the silver coin onto the printing platform 33 for fixation through negative pressure. The slide assembly 31 also includes a coin scraper 37 mounted above the printing platform 33. A feeding port 38 is provided on the color printing base 29 below the printing platform 33, connected to a coin drop channel 39. When the printing platform 33 moves towards the conveying channel 8, it can receive silver coins. After color printing, when the printing platform 33 moves away from the conveying channel 8, the silver coins are scraped by the coin scraper 37 and fall into the coin drop channel 39. The slide assembly 31 also includes a third sensor 40 located at the front and rear ends of the travel path of the third slider 35. Any existing sensor corresponding to the third sensor 40 can be installed on the third slider 35 for precise control of the travel of the printing platform 33. The third sensor 40 is electrically connected to the control center 2 and centrally controlled by the control center 2.
[0045] The UV color printing assembly 30 includes a fourth linear module 41 mounted above the printing platform 33. The fourth linear module 41 is arranged vertically and includes a fourth slider 42. The fourth slider 42 is fixedly connected to a color printing bracket 43, which is connected to a UV color printing head 44 and a UV curing lamp 45. The fourth linear module 41 can drive the UV color printing head 44 to move to a corresponding position above the printing platform 33 to print on the coin, and the fourth linear module 41 can also drive the UV curing lamp 45 to move to a corresponding position above the printing platform 33 to cure the UV ink on the coin. The UV color printing head 44 performs the color printing function and can be implemented using any existing technology. The UV color printing assembly 30 also includes a fourth sensor 46 disposed on the color printing bracket 43. Any existing sensing element corresponding to the fourth sensor 46 can be disposed at the front end of the travel path of the fourth slider 42, which is used to precisely control the UV color printing head 44 to move to the top of the printing platform 33 for precise positioning. The fourth sensor 46 is electrically connected to the control center 2 and is centrally controlled by the control center 2.
[0046] The lifting ink stack 32 is positioned on the travel path of the fourth slider 42. The lifting ink stack 32 includes a moisturizing tank 47 at the top and a scraper 48 on one side. The lifting ink stack 32 can be implemented using any existing technology, enabling precise lifting. The inkjet head of the UV color printer head 44 can be placed in the moisturizing tank 47 of the lifting ink stack 32, keeping the inkjet head moist and preventing clogging due to ink drying. This maintains the good condition of the inkjet head, ensuring the normal operation of subsequent printing. It also absorbs residual ink on the inkjet head, preventing ink accumulation or dripping into the printer's interior and surrounding environment, thus avoiding ink waste and environmental pollution. During inkjet head cleaning, it works in conjunction with the scraper 48, adjusting its position through lifting to ensure a more thorough cleaning of the inkjet head, guaranteeing ink output accuracy and quality.
[0047] The casing 1 is equipped with a door 49. The receiving mechanism 5 includes a coin receiving box 50 located inside the door 49 and open upwards, and a coin retrieval port 51 located outside the door 49 and communicating with the coin receiving box 50. The opening of the coin receiving box 50 corresponds to the output end of the coin dropping channel 39. After the silver coins are printed, they automatically fall into the coin receiving box 50 through the coin dropping channel 39. Users can retrieve the customized silver coins through the coin retrieval port 51. The door 49 is equipped with a touch screen 52 and a display area 53. Users can operate the device through the touch screen 52, which is electrically connected to the control center 2. The display area 53 includes a display box 54 located inside the door 49 and a display panel 55 located outside the door 49. The display panel 55 is made of transparent material and allows a view of the interior of the display box 54. Users can view the sample customization effect through the display area 53 to assist them in selecting suitable silver coins for customization.
[0048] Working principle:
[0049] Users operate on the touchscreen 52, such as scanning a code, selecting the coin storage channel 7 according to the type of coin, uploading a mobile phone image, and after payment, the coin pusher component 10 pushes the coin at the bottom of the corresponding coin storage channel 7 into the conveying channel 8. The slide component 31 drives the printing platform 33 to approach the conveying channel 8, and the transmission component 17 drives the conveying block 9 to transport the coin onto the printing platform 33. The printing platform 33 uses negative pressure to attract the coin and then resets. The UV color printing component 30 prints the coin. After the color printing is completed, the slide component 31 continues to move, and the coin scraper 37 scrapes the coin into the coin drop channel 39 and transports it into the coin receiving box 50. Users can then take the coin away through the coin retrieval port 51.
