Description

Technical Field

[0001] This application relates to the technical field of vending machines, and in particular to an automatic beverage vending machine. Background Technology

[0002] With the development of modern business models, vending machines have become a convenient tool for selling goods in various places. Especially in public places such as subway stations, shopping malls, and schools, vending machines are favored by consumers because they do not require human intervention and provide 24-hour service.

[0003] Beverage sales are a key application in these vending machines, especially the automatic sale of bottled water, carbonated drinks, and juices. Users select their desired beverage and complete payment on the touchscreen or button panel of the vending machine. The beverage then falls into a collection box by gravity, which users can then use to retrieve their drink from the collection slot.

[0004] However, carbonated beverages contain dissolved carbon dioxide gas. When a bottle or can of carbonated beverage falls into the pickup box, it will be impacted, and the carbon dioxide gas in the liquid may be released rapidly from the liquid, producing a large number of bubbles in the beverage. When the user opens the bottle, the bubbles will rush out instantly, which may cause the beverage to spray or splash out. Summary of the Invention

[0005] To address the issue of beverage spillage after opening when carbonated drinks are dropped and impacted, this application provides an automated beverage vending machine.

[0006] The automatic beverage vending machine provided in this application adopts the following technical solution:

[0007] An automatic beverage vending machine includes a cabinet body and a cabinet door. The cabinet body is provided with a plurality of placement frames for placing beverages. The bottom of the cabinet body is provided with a retrieval port. A movable plate is vertically slidable inside the cabinet body. The movable plate is located between the placement frames and the cabinet door. The cabinet body is provided with a drive component for pushing the movable plate to move vertically. The placement frames are provided with a push component for pushing beverages to move onto the movable plate.

[0008] By adopting the above technical solution, when the user selects the desired beverage, the moving plate moves vertically to the height of the selected beverage under the action of the driving component. The pushing component pushes the beverage on the placement box onto the moving plate, and the moving plate moves the beverage downward to the retrieval port for easy retrieval. The beverage moves smoothly under the action of the moving plate and will not collide violently, thereby reducing the possibility of the beverage spraying after opening.

[0009] Preferably, the drive assembly includes a vertically arranged screw and a guide rod, with movable blocks fixed on both sides of the movable plate, and sliding grooves respectively opened on the opposite inner sides of the cabinet. The movable blocks slide vertically with the cabinet through the sliding grooves. One of the movable blocks is sleeved on the outer periphery of the screw and the movable block is threadedly driven with the screw. The other movable block is sleeved on the outer periphery of the movable plate. A motor is installed inside the cabinet, and the output end of the motor is fixedly connected to the end of the screw.

[0010] By adopting the above technical solution, the motor is started, the motor drives the screw to rotate, and the moving block drives the moving plate to move vertically, so that the moving plate can move to the height corresponding to the beverage to be selected.

[0011] Preferably, the pushing component includes a plurality of cylinders, each corresponding to a placement frame. A push plate is fixed to the end of the piston rod of each cylinder, and the push plate can abut against the beverage in the placement frame. The push plate moves along the length of the placement frame.

[0012] By adopting the above technical solution, cylinder one is activated, which drives the pusher to move the beverage in the placement box toward the moving plate, thereby moving the beverage to the top surface of the moving plate.

[0013] Preferably, vertically arranged rotating rods are rotatably mounted on the opposite inner sides of the placement frame. A baffle is fixedly fitted around the outer periphery of the rotating rod. The side of the baffle near the first cylinder can abut against the beverage. A torsion spring is fitted around the outer periphery of the rotating rod. The top end of the torsion spring is fixedly connected to the baffle, and the bottom end of the torsion spring is fixedly connected to the inner bottom surface of the placement frame. A stop block is fixed to the bottom surface of the baffle. A stop groove is formed on the inner bottom surface of the placement frame. The side of the stop block near the first cylinder can abut against the inner side of the stop groove.

[0014] By adopting the above technical solution, when the push plate stops moving, the baffle abuts against the beverage in the placement box under the elastic force of the torsion spring, and the abutting block is located in the abutting groove, making it difficult for the beverage in the placement box to fall off.

[0015] Preferably, the inner bottom surface of the picking port is provided with a clearance groove, the movable plate can be inserted into the clearance groove, a second cylinder is installed in the picking port, a push plate is fixed to the piston rod end of the second cylinder, and the push plate moves along the width direction of the movable plate.

[0016] By adopting the above technical solution, the moving plate moves the beverage downwards. When the moving plate moves into the clearance slot, cylinder two is activated. Cylinder two drives the push plate to move towards the moving plate. The push plate pushes the beverage on the top surface of the moving plate to the bottom surface of the retrieval port, so that the user can pick up the beverage. At the same time, it facilitates the moving plate to move upwards.

[0017] Preferably, the top surface of the movable plate is provided with a dovetail groove, and a dovetail block is slidably mounted on the movable plate along its own length direction through the dovetail groove. A limit plate is fixed on the top surface of the dovetail block. A magnetic block one for attracting the dovetail block is fixed on the side of the dovetail groove away from the screw. A pull rope is fixed on the side of the dovetail block away from the magnetic block one. A through hole one for passing through the pull rope is provided on the inner wall of the dovetail groove away from the magnetic block one. A through hole two communicating with the through hole one is provided on the top surface of the movable block. One end of the pull rope away from the dovetail block passes through the through hole one and the through hole two in sequence and is fixedly connected to the inner top surface of the sliding groove.

[0018] By adopting the above technical solution, during the downward movement of the moving plate, the pull rope drives the dovetail block to move away from the magnetic block, so that the limiting plate can push the beverage on the top surface of the moving plate to the side close to the screw, so that the pushing plate can push the beverage on the top surface of the moving plate.

[0019] Preferably, a sliding groove is provided on the inner side wall of the loading port near the screw. A sliding plate is installed on the cabinet body along the length of the moving plate through the sliding groove. A sliding rod is fixed to the side of the sliding plate.

An electromagnet is fixed to the inner side of the sliding groove. When the electromagnet is energized, it can attract the pressure plate.

[0020] By adopting the above technical solution, when the moving plate moves downward into the relief groove, the electromagnet is energized and works. The electromagnet attracts the pressure plate, and the pressure plate drives the sliding plate to move into the sliding groove through the sliding rod. When the moving plate moves upward and disengages from the relief groove, the electromagnet is de-energized. Under the elastic force of the spring, the sliding plate moves towards the beverage and pushes the beverage away from the sliding plate, so that the subsequent pushing plate can push the next bottle of beverage to the bottom of the dispensing port.

[0022] By adopting the above technical solution, when the moving plate moves downward into the clearance groove, the bottom surface of the moving plate abuts against the control block and pushes the control block downward, so that the moving plate and the fixed plate make electrical contact, and the electromagnet is energized and works.

[0023] Preferably, a reset block is fixed to the side of the control block, a reset groove is provided on the inner wall of the control slot, the reset block slides vertically with the cabinet through the reset groove, and a second spring is fixed to the bottom surface of the reset block, the bottom end of the second spring being fixedly connected to the inner bottom surface of the reset groove.

[0024] By adopting the above technical solution, when the moving plate disengages from the clearance groove, the control block moves upward under the elastic force of the second spring, causing the moving plate to separate from the fixed plate and the electromagnet to be de-energized.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. After the user selects the desired beverage, the moving plate moves vertically to the height of the selected beverage under the action of the drive component. The pushing component pushes the beverage on the placement box onto the moving plate. The moving plate moves the beverage downward to the retrieval port for easy retrieval. The beverage moves smoothly under the action of the moving plate and will not collide violently, thereby reducing the possibility of the beverage spraying after opening.

[0027] 2. The moving plate moves the beverage downwards. When the moving plate moves into the clearance slot, cylinder two is activated. Cylinder two drives the push plate to move towards the moving plate. The push plate pushes the beverage on the top surface of the moving plate to the bottom surface of the retrieval port, so that the user can pick up the beverage. At the same time, it facilitates the moving plate to move upwards.
