Description

Technical Field

[0001] This application relates to the technical field of fresh rice vending machines, especially self-service integrated fresh rice vending machines. Background Art

[0002] Milling rice refers to removing the husk layer of paddy through specific mechanical equipment to obtain the rice we eat daily. Currently, the rice on the market is usually processed and packaged in advance and directly sold in places such as supermarkets.

[0003] The processed rice is sold by loose weighing or packaged in bags. Since the rice will be stored for a period of time according to the sales situation during the sales process, the freshness will decrease, which will affect the taste of the rice. To improve the fresh taste of the rice, people will choose self-service rice processing and vending machines. The Chinese Patent Network discloses a multi-bin self-service fresh rice milling machine with the application number: CN202020652198.2, including a machine body. A rice milling machine is fixedly connected inside the machine body; a rice milling machine feed hopper is fixedly connected to the feed inlet of the rice milling machine. A rice milling machine discharge pipe is communicated with the front end of the rice milling machine, and a rice milling machine bran outlet is communicated with one side of the rice milling machine; the rice milling machine feed hopper is communicated with a grain bin through a blower; the discharge port of the rice milling machine discharge pipe extends out of the front end face of the machine body; the rice milling machine bran outlet is communicated with a bran collection box; a control knob for controlling the outlet opening degree adjusting device to adjust the outlet opening degree of the rice milling machine is arranged on the front end face of the machine body. The front end face of the machine body is successively provided with a rice taking groove and an operating table from bottom to top. It can complete self-service rice milling and vending, ensuring the quality and freshness of the rice.

[0004] However, there are still certain drawbacks in the above-mentioned self-service rice milling machine during use. People can directly contact the rice outlet during the process of taking or receiving rice, and the rice and bran cannot automatically switch the receiving bags (it is not convenient to organize the receiving bags, and the bottom end of the receiving bag is prone to wrinkles when receiving rice and bran, making the rice or rice bran easy to overflow from the receiving bag). During this process, if the operation is improper, the rice is easy to leak, and if people directly contact the rice receiving port, food hygiene cannot be guaranteed; and the existing rice vending machines have a single function. In view of this, this application proposes a self-service integrated fresh rice vending machine. Summary of the Invention

The side door 14 is detachable from the feeding port, and the side wall of the body 1 is also connected to a protective plate 15 located above the side door 14 to prevent water from seeping into the control chamber 5 on rainy days.

[0059] Among them, the material receiving auxiliary part 8 includes a material receiving tray 81, and two pairs of material receiving cavities 82 are opened at the upper end of the material receiving tray 81 for switching to complete the receiving of rice and bran; the upper end of the material receiving cavity 82 is fixedly connected to a support ring, and when the material receiving bag is put on, the upper end of the material receiving bag is rolled up on the outside of the support ring. The support ring is an existing technical structure and is not shown in the figure.

[0060] A rotary drive member 2 that cooperates with the horizontal drive member 9 to start is installed at the upper end of the pallet 7. The rotary drive member 2 is used to complete the steering of the receiving tray 81, assisting in the automatic rice receiving process.

[0061] The horizontal drive member 9 includes a strip-shaped conveying cylinder 92 slidably disposed in the conveying cavity 10. An air-operated bag arranging member 11 is installed on the strip-shaped conveying cylinder 92. The air-operated bag arranging member 11 is used to adsorb and arrange the receiving bags in the receiving cavity 82, so that the bottom end of the receiving bag adheres to the inner wall of the receiving cavity 82, thereby preventing the receiving bag from being crushed when receiving rice or rice bran.

[0062] Specifically, the horizontal drive member 9 includes a conveying rack 93 fixedly connected to the bottom end of the strip-shaped conveying cylinder 92. A second motor 95 is embedded in the pallet 7 on one side of the conveying cavity 10. A second gear 94 meshing with the conveying rack 93 is fixedly sleeved on the output shaft of the second motor 95. Bearings are embedded in the inner wall of the conveying cavity 10, and the end of the output shaft of the second motor 95 is fixedly connected to the inner ring of the bearing, which plays a role in supporting and balancing the output shaft of the second motor 95.

[0063] A support cylinder 91 is rotatably connected to the upper end of the strip-shaped conveying cylinder 92. A mechanical seal is embedded in the upper end of the strip-shaped conveying cylinder 92, and the bottom end of the support cylinder 91 is fixedly connected to the inner ring of the mechanical seal. The receiving tray 81 is fixedly connected to the upper end of the support cylinder 91.

[0064] Among them, the pallet 7 is driven by a pushing member 19. The pushing member 19 includes a connection cavity 191 opened inside the pallet 7. An electric telescopic rod 192 is installed on the inner wall of one side of the control cavity 5, and the telescopic end of the electric telescopic rod 192 is fixedly connected to the inner wall of the connection cavity 191, so that the receiving auxiliary member 8 at the upper end of the pallet 7 can extend out of the control cavity 5, facilitating the removal of the loaded rice and rice bran. Preferably, two sets of pushing members 19 are provided.

[0065] In this embodiment, support seats 83 are fixedly connected to the lower inner walls of both pairs of receiving cavities 82. A weight sensor 84 is embedded in the support seat 83. The sensing weight of the weight sensor 84 is preset. When the material on its upper end reaches the set weight, the weight sensor 84 will send a signal.

[0066] Among them, the rotary drive member 2 includes a transmission gear disc 21 fixedly sleeved on the side wall of the bottom end of the receiving tray 81. A first motor 22 is embedded in the pallet 7 on one side of the end of the conveying cavity 10. The output shaft of the first motor 22 penetrates the upper surface of the pallet 7 and is fixedly connected to a rotating shaft 23. A first gear 24 is fixedly sleeved on the side wall of the rotating shaft 23. When the receiving auxiliary member 8 is in the receiving state, the transmission gear disc 21 moves to one end of the first gear 24 and meshes with the first gear 24.

[0067] Furthermore, the pneumatic bag arranging member 11 includes a pneumatic cover 1111 fixedly connected to the inner wall of the upper end of the strip-shaped conveying cylinder 92. A first air inlet hole 114 communicating with the support cylinder 91 is formed in the upper ends of the strip-shaped conveying cylinder 92 and the pneumatic cover 1111 together.

[0068] A second air inlet hole 115 is formed at the bottom end of the pneumatic cover 1111 close to one side of the rotary driving member 2. One end of the strip-shaped conveying cylinder 92 close to the rotary driving member 2 is open. A sealing plate 119 is fixedly connected to the open end of the strip-shaped conveying cylinder 92. A piston plate 117 located below the pneumatic cover 1111 is slidably connected in the strip-shaped conveying cylinder 92. One end of a push-pull rod 118 is fixedly connected to the inner side wall of the conveying cavity 10, and the other end of the push-pull rod 118 slidably penetrates through the sealing plate 119 and is fixedly connected to the piston plate 117. The air pressure in the pneumatic cover 1111 is controlled by the sliding of the piston plate 117, and further the air pressure in a plurality of air conveying covers 112 is controlled.

[0069] Wherein, a plurality of adsorption air holes 111 are formed at the bottom end of the material receiving tray 81. The adsorption air holes 111 penetrate through the support base 83. The plurality of adsorption air holes 111 are distributed in two pairs in a ring shape at the bottom end of the material receiving tray 81. Two pairs of air conveying covers 112 are connected to the bottom end of the material receiving tray 81. The two pairs of air conveying covers 112 are respectively located below the two pairs of adsorption air holes 111 distributed in a ring shape.

[0070] The two pairs of air conveying covers 112 are respectively communicated with the support cylinder 91 through connecting air pipes 113. A ventilation hole 1110 is formed at one end of the strip-shaped conveying cylinder 92 far from the second air inlet hole 115, so that the air pressure in the strip-shaped conveying cylinder 92 is balanced, and the piston plate 117 can slide smoothly in the strip-shaped conveying cylinder 92.

[0071] It should be noted that a through hole is formed in the sealing plate 119, and a rubber ring is embedded in the through hole. The push-pull rod 118 slides on the inner wall of the rubber ring, so that the gas in the strip-shaped conveying cylinder 92 will not be discharged outward through the through hole when the piston plate 117 slides, and further the air pressure in a plurality of air conveying covers 112 can be controlled smoothly.

[0072] In this application, a support ring 12 is connected to the bottom ends of a plurality of air conveying covers 112 together. A pair of arc-shaped grooves 17 are formed at the upper end of the strip-shaped conveying cylinder 92. The support ring 12 is slidably connected in the two arc-shaped grooves 17, which can play a role in balancing and supporting the material receiving auxiliary member 8.

[0073] Wherein, a vending box 13 is arranged on the side wall of the machine body 1 far from the side door 14. A plurality of storage cavities are arranged in the vending box 13. A two-dimensional code is arranged on the vending box 13. Customers can purchase the goods in the vending box 13 by scanning the two-dimensional code. After payment, the cabinet door of the cabinet body will automatically pop open. After the consumer takes out the goods in the cabinet door and closes the cabinet door, the transaction is completed.

[0074] In this embodiment, in combination with Figure 9 , it further includes a controller. Both pairs of weight sensors 84 are electrically connected to the controller, and the output end of the controller is electrically connected to the solenoid valve 16 and the first motor 22. Set the maximum limit weight for the weight sensors 84 for receiving rice and rice bran. When receiving rice and rice bran simultaneously, when one of the weight sensors 84 senses that the weight value reaches the standard, it will send an electrical signal to the controller.

[0075] The output end of the controller is also electrically connected to the electric telescopic rod 192 and the second motor 95, and the working states of the electric telescopic rod 192 and the second motor 95 are controlled by the controller.

[0076] The working principle of this embodiment is as follows: When working, after the customer selects the type and weight of paddy on the touch screen, the system issues an instruction to control the corresponding module to work for production and processing. The paddy in the storage bin 3 is pushed into the feeding air duct, and the feeding fan blows the paddy in the pipeline to the temporary storage bin for processing at the top, and then it falls into the rice milling machine for peeling processing. Before selecting the paddy, the controller is started through the touch screen to make the telescopic ends of the two electric telescopic rods 192 extend, so that the support plate 7 and the side door 14 slide to one side, and further make the material receiving auxiliary part 8 move out of the outer side of the control cavity 5. Then, a material receiving bag is sleeved into the two pairs of material receiving cavities 82. The material receiving bag is a transparent plastic bag (a support sleeve rod 18 is arranged on the upper end of the support plate 7 near the side door 14, and a roll of plastic bag is sleeved on the support sleeve rod 18, and the plastic bag can be used in matching with the material receiving cavity 82). After the material receiving bags are sleeved in all four material receiving cavities 82, the controller controls the telescopic ends of the electric telescopic rods 192 to retract, driving the support plate 7 to move into the control cavity 5, so that one pair of the material receiving cavities 82 are respectively located directly below the rice outlet pipe 61 and the bran outlet pipe 62. The processed rice and bran will respectively fall into the material receiving bags in two of the material receiving cavities 82 through the rice outlet pipe 61 and the bran outlet pipe 62. At this time, when one of the weight sensors 84 at the bottom of the two material receiving cavities 82 senses that the weight reaches the set weight value, the corresponding weight sensor 84 will send an electrical signal to the controller, and the two solenoid valves 16 are controlled to be temporarily closed through the controller. Subsequently, the first motor 22 is started through the controller. The output shaft of the first motor 22 rotates to drive the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, the first gear 24 meshes with the transmission gear disc 21 for transmission, thereby driving the material receiving cavity 82 to rotate by 90 degrees, so that the other pair of material receiving cavities 82 are respectively located below the rice outlet pipe 61 and the bran outlet pipe 62. The controller then controls the two solenoid valves 16 to open. After the rice and bran are discharged, the controller starts the second motor 95 again, so that the output shaft of the second motor 95 rotates in the reverse direction, and then the second gear 94 meshes with the transmission rack 93 in the reverse direction for transmission, driving the material receiving auxiliary part 8 to move away from the rotary drive part 2. Next, the controller starts the electric telescopic rod 192 to make the telescopic end of the electric telescopic rod 192 extend, so that the support plate 7 and the material receiving auxiliary part 8 extend out of the control cavity 5, and then the rice and bran in the four material receiving cavities 82 are taken out. The whole process automatically completes rice receiving without the need for manual valve closing and material receiving bag replacement; people will not come into contact with the rice outlet pipe 61 and the rice outlet pipe 61, ensuring the hygienic state of self-service vending. After the rice is taken out, the support plate 7 is retracted into the control cavity 5.

[0077] In this application, by arranging a pneumatic bag arranging component 11 on the strip-shaped conveying cylinder 92, when the strip-shaped conveying cylinder 92 moves towards the inner side of the control cavity 5, the push rod 118 will push the piston plate 117 towards the inside of the strip-shaped conveying cylinder 92. When the piston plate 117 moves away from the rotary driving component 2, the gas in the air pressure cover 1111 will be discharged through the second air outlet hole 115, so that the gas in several air conveying covers 112 is sucked into the air pressure cover 1111 through the first air inlet hole 114. Furthermore, a plurality of groups of air adsorption holes 111 will supply air into several air conveying covers 112, thereby enabling the bottoms of the receiving bags in several receiving cavities 82 to be adsorbed in the receiving cavities 82. When receiving rice or rice bran, the rice and rice bran can smoothly fall into the receiving bags. After the receiving is completed, the strip-shaped conveying cylinder 92 moves away from the rotary driving component 2, and the piston plate 117 will slide reversely in the strip-shaped conveying cylinder 92, squeezing the gas inside the strip-shaped conveying cylinder 92 into the air pressure cover 1111 through the second air outlet hole 115, and then inputting it into several air conveying covers 112 through the first air inlet hole 114, so that a certain amount of gas is output upwards by several groups of air adsorption holes 111, and further enabling the bottoms of the receiving bags in several receiving cavities 82 to return to the loose state, which is convenient for taking out the receiving bags filled with rice or rice bran later (preventing the bottom of the receiving bag from being broken due to adsorption during material taking).

[0078] The above specific embodiments are only the preferred embodiments of this application. Based on the technical solution of this application and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of this application and do not limit this application.
