Description

Technical Field

[0001] The present application belongs to the technical field of food processing, and in particular to a food vending machine. Background Art

[0002] The automatic food vending devices currently on the market generally include a heating mechanism and an output mechanism, and use the heating device in the heating mechanism to heat and cook the food, and then output it for sale through the output mechanism. The commonly used output mechanism generally uses a conveyor belt to transfer the position of the food workpiece in the horizontal direction, but the use of a conveyor belt will increase the occupied space and limit the volume of the entire device. The device needs to reserve space for installing the conveyor belt and its drive mechanism, which in turn limits the overall shape and size of the entire device. In the prior art, a manipulator is used to replace the conveyor belt, but the cost of setting up a manipulator is higher, which is not conducive to popularization and application in the market. Secondly, the power supply of the device mainly comes from the heating mechanism. If a conveyor belt is set up in the output mechanism, a certain amount of energy consumption will be generated, resulting in increased energy consumption.

[0003] In addition, since the workpiece transferred in the device is cooked food, and the heating mechanism and the output mechanism on the device are interconnected, after long-term use, pollutants such as cooking fumes will accumulate inside the device, and the conveyor belt is arranged inside the device for operation, and pollutants such as oil will accumulate on the conveyor belt, causing the conveyor belt to operate abnormally, easily get stuck or require greater power to operate, further increasing energy consumption and seriously affecting the normal operation of the device.

[0004] Therefore, the food vending devices in the prior art still have many defects, which is a technical problem that the current vending equipment research and development manufacturers urgently need to solve. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a food vending machine, which improves the transmission mechanism in the device and effectively solves the problem that the conveyor belt used in traditional food vending devices is easily affected by pollutants such as oil generated by cooking food.

[0006] To achieve the above-mentioned purpose, the technical solution adopted in the present application is: to provide a food vending machine, comprising a heating mechanism, a conveying mechanism and a storage mechanism connected in sequence, the heating mechanism comprising a heating device and a support table for carrying a workpiece, the heating device heats the workpiece on the support table; the conveying mechanism comprises a lifting platform arranged between the heating mechanism and the storage mechanism, the storage mechanism comprises at least two storage tables arranged up and down, the lifting platform can be displaced up and down to switch to the setting height of each storage table; the upper surfaces of the support table, the lifting platform and the storage table are respectively provided with balls, and the support table, the lifting platform and the storage table are arranged to be inclined in the same direction in sequence.

[0007] The beneficial effect of the food vending machine provided by the present application is that: compared with the prior art, the food vending machine has three major mechanisms of heating, conveying and storage, wherein the heating mechanism is provided with a heating device, which can heat and cook the food workpieces placed on the support table. The storage mechanism has more than two storage tables, and each storage table is arranged up and down, which can effectively save storage space and is conducive to the allocation and storage of food workpieces, thereby realizing automated storage management. The conveying mechanism has a lifting platform, and can move up and down to switch the height, so as to distribute the received food workpieces to each storage table, thereby forming a multifunctional integrated automated equipment for food heating and cooking, food sorting, and allocation and storage.

[0008] In order to transfer the position of food workpieces in the horizontal direction between various mechanisms, compared with the commonly used conveyor belts in the prior art, the vending machine of the present application is provided with balls that can allow the food workpieces to slide on the upper surfaces of the support platform, the lifting platform and the storage platform, and the support platform, the lifting platform and the storage platform are tilted in the same direction in sequence. After the food is cooked, the user can operate the machine to tilt the support platform toward the lifting platform, so that the food slides onto the lifting platform under the action of gravity, and is distributed to each storage platform through the lifting platform, thereby realizing the automatic transfer operation of the position of the food workpiece, without applying force or manual operation, effectively saving labor costs and equipment energy consumption, and improving the automation performance of the equipment. In this way, since there is no need to set up a conveyor belt, it can effectively avoid being easily affected by the oil stains generated by cooking in the machine when using the conveyor belt, which is convenient to clean, stable in operation and not easy to get stuck; and it can save the occupied space inside the machine and reduce the counterweight, so as to facilitate the transfer of the machine to the sales location, and effectively improve the user experience.

[0009] The structure of the heating mechanism is improved. The heating mechanism includes a container for accommodating the support platform and the heating device, and the container is provided with an output port for discharging materials to the conveying mechanism; the heating mechanism also includes a driving cylinder located at the bottom of the container, and a pull rod is connected to the driving cylinder, and the pull rod is connected to the side of the support platform located at the output port; a first rotating shaft located at the bottom of the support platform is provided in the container, and a first connecting ear sleeved with the first rotating shaft is provided in the middle of the support platform; the driving cylinder drives the pull rod to move downward so that the support platform is tilted toward the lifting platform with the first rotating shaft as the axis. The middle part of the support platform is sleeved with the first rotating shaft through the first connecting ear so that the support platform can be turned horizontally. During the heating and cooking process, the pull rod can support one side of the support platform so that the support platform can maintain a horizontal state, so that the heating device in the container can heat and cook the food on the support platform. When the food is cooked, the driving cylinder is started to drive the pull rod downward so that the support platform is turned horizontally and tilted toward the lifting platform. Under the action of gravity and the balls on the support table, the food slides from the support table to the lifting table, effectively realizing the automatic discharging operation.

[0010] Furthermore, an inlet for workpieces is provided on one side of the container, and a guide platform is provided between the inlet and the support platform, and the guide platform is inclined toward the support platform. In practical applications, due to the small area of ​​the inlet, it is difficult to set a guide device that can drive the food workpiece, and it is generally necessary to put the food workpiece into the container manually or with tools. However, when the machine is in working state, the container maintains a high temperature, which can easily cause damage to the human body. The food vending machine of the present application is provided with a guide platform between the inlet and the support platform, and the guide platform is inclined toward the support platform. The user only needs to place the food on the guide platform, and the food can slide toward the support platform along with the guide platform under the action of gravity, thereby realizing automatic feeding operation, effectively eliminating safety hazards, and improving feeding efficiency.

[0011] Furthermore, the container is provided with a fan capable of generating airflow, the fan is arranged on a side symmetrical to the inlet, and the support platform is inclined toward one side of the fan; the heating device includes an upper heating ring and a lower heating ring, the support platform is arranged between the upper heating ring and the lower heating ring, and the upper heating ring and the lower heating ring are respectively connected to a temperature control device. First, the fan arranged in the container is used to increase the flow rate and coverage of the high-temperature airflow in the container, so that the food is heated more evenly, and the heating speed and cooking effect are effectively improved. Secondly, the support platform is inclined toward one side of the fan, so that after the food enters the container through the inlet, it is concentrated toward the inside of the container under the action of the balls on the support platform and gravity, so that the food can be evenly placed on the support platform, effectively increasing the capacity of the support platform, which is more conducive to the food being evenly heated, thereby improving the cooking effect. Thirdly, the heating device includes an upper heating ring located above the support platform and a lower heating ring located below the support platform, thereby forming an upper and lower heating structure, so that the food can be heated from the upper and lower sides of the support platform, so that the food is heated more evenly, the cooking effect is effectively improved, and the internal space of the container can be maximized to improve the heating and cooking efficiency. In addition, the upper heating ring and the lower heating ring are respectively connected to a temperature control device, so as to control the upper heating ring and the lower heating ring respectively, effectively improving the heating performance and safety guarantee.

[0012] The installation structure of the ball bearing is improved. The support platform is provided with a plurality of nuts, which are radially arranged on the support platform; a grid penetrating the upper and lower surfaces of the support platform is provided on the support platform, and the nut is provided in the grid; each nut is provided with a top cap, and the top cap is provided with a mounting groove for installing the ball bearing. The ball bearing is arranged by using the top cap on the nut, and a plurality of nuts are evenly distributed on the support platform, which is conducive to the sliding of the food workpiece. Among them, the support platform is provided with a grid capable of installing nuts. On the one hand, it is conducive to the heat generated by the lower heating ring at the bottom of the support platform passing through the grid and rising to the upper surface of the support platform, thereby improving the heat transfer effect; on the other hand, the grid also discharges the food oil stains during the cooking process to the bottom of the container, avoiding the food and oil stains from flowing to the lifting platform together when the support platform is tilted to discharge the material, effectively reducing the influence of oil stains during the cooking process on the product, and reducing the hygienic impact on the inner cavity of other mechanisms.

[0013] Furthermore, the guide platform, the lifting platform and the storage platform are respectively provided with a plurality of mounting holes for mounting the balls, and a mounting box for fixing the balls is provided at the bottom of the mounting holes. The upper surfaces of the guide platform, the lifting platform and the storage platform are respectively provided with a plurality of balls, and the plurality of balls are evenly distributed on each table surface. In order to allow each ball to operate independently, a mounting box located below the mounting hole is provided on each table surface, and the mounting box is used to accommodate and cover the balls for protection, effectively preventing foreign objects from penetrating and causing the balls to get stuck, so that the balls can maintain smooth operation and improve the sliding efficiency of the food workpiece.

[0014] Furthermore, the upper surfaces of the guide platform and the lifting platform are respectively provided with bosses arranged around the outer circumference of the mounting hole. The bosses are used to support the food workpieces sliding on each table surface, so that the bottom of the food workpiece is isolated from the table surface, effectively reducing the adhesion of the food workpiece to the table surface, avoiding the jamming of the food workpiece position transfer, and improving the smoothness of sliding.

[0015] The structure of the conveying mechanism is improved, and the conveying mechanism also includes a guide assembly connected to both sides of the lifting platform, and a driving motor is provided at the bottom of the lifting platform; the guide assembly includes a screw rod and a slider, and the slider is fixedly connected to the lifting platform, and slides on the screw rod as the driving motor drives the lifting platform to move up and down. The guide assembly is used to stably guide the up and down displacement of the lifting platform to prevent the lifting platform from tipping over easily during the displacement process, which causes the food workpiece on the lifting platform to slip and deviate. The lifting platform can accurately guide the food workpiece to the corresponding storage platform, effectively improving the up and down displacement stability of the lifting platform.

[0016] The structure of the storage mechanism is improved, and the storage mechanism also includes a door panel, and at least two access ports corresponding to the positions of the storage platform are provided on the door panel; a receiving pocket capable of supporting workpieces is provided outside the door panel, and the receiving pocket is connected to the access port; the storage mechanism also includes a trigger rod, a second rotating shaft and a third rotating shaft located at the bottom of each storage platform, a second connecting ear sleeved with the second rotating shaft is provided in the middle of the storage platform, and the storage platform can be horizontally flipped with the second rotating shaft as the axis; a guide hole extending toward the access port is provided on one end of the storage platform close to the receiving pocket; the trigger rod is fixed on the third rotating shaft, and one end of the trigger rod passes through the guide hole and extends to the upper surface of the lifting platform, and the other end of the trigger rod is provided with a hook; one end of the storage platform is provided with a closed door arc plate capable of covering the access port, and the lower edge of the closed door arc plate is buckled with the hook of the trigger rod. Wherein, the guide hole is preferably a long strip hole that can be passed through by the end of the trigger rod. When the storage table receives the food workpiece, the front end of the food workpiece pushes against the end of the trigger rod on the storage table, so that the trigger rod rotates along the guide hole with the third rotating shaft as the axis, so that the hook on the other end of the trigger rod is separated from the door-closing arc plate. At the same time, after the food workpiece hits the trigger rod, the food workpiece slides from the input end of the storage table to the output end of the storage table, and because the storage table itself is tilted, the gravity of the storage table is transferred to the output end, so that the storage table is turned horizontally, and the door-closing arc plate moves downward to open the access port. At this time, the food workpiece can smoothly pass through the access port from the storage table and slide to the receiving pocket outside the door panel, so that the user or customer can take the food. When the food workpiece slides to the receiving pocket, the counterweight on the storage table changes, so that the storage table and the trigger rod are reset, so that the door-closing arc plate moves up and blocks the access port, and the hook of the trigger rod is restored to the lower edge of the door-closing arc plate. In this way, an automatic opening and closing door structure is formed on the storage mechanism, and the unloading operation is automatically completed without human intervention, which effectively improves the automation performance of the machine.

[0017] Furthermore, a baffle extending downward is hingedly connected to one end of the storage platform close to the lifting platform, and the baffle has a weight; a baffle extending downward is provided at one end of the lifting platform close to the storage platform, and the lower edge of the baffle is provided with a flange that cooperates with the baffle for guidance. On the one hand, the baffle with a weight is used to balance the storage platform to maintain an inclined state. On the other hand, the baffle can block the food artifacts on the lifting platform to prevent the food artifacts from sliding out at will. Only after the lifting platform is moved up and down to a corresponding height, the food is allowed to slide out to the storage platform at the corresponding height. In addition, a baffle is provided on the end of the lifting platform, and the lower edge of the baffle is provided with a flange, so that the flange can cooperate with the baffle for guidance, so that the lifting platform can smoothly move up and down between storage platforms of various heights, effectively avoiding mutual interference and jamming.

[0044] The food vending machine provided in the embodiment of the present application is now described. Figure 1 The food vending machine includes a heating mechanism 100, a conveying mechanism 200 and a storage mechanism 300 connected in sequence. Figure 1 and Figure 2 The heating mechanism 100 includes a heating device 1 and a support table 2 for carrying a workpiece, and the heating device 1 can heat the workpiece on the support table 2. The conveying mechanism 200 includes a lifting platform 3 arranged between the heating mechanism 100 and the storage mechanism 300. The storage mechanism 300 includes at least two storage tables 5 arranged up and down, and the lifting platform 3 can move up and down to switch to the setting height of each storage table 5. The upper surfaces of the support table 2, the lifting platform 3 and the storage table 5 are respectively provided with balls 6 for allowing the workpiece to slide, and the support table 2, the lifting platform 3 and the storage table 5 are successively tilted in the same direction.

[0045] It should be noted that, in actual applications, food can preferably be loaded on a tray, by utilizing the bottom surface of the tray to cooperate with the support table 2, the lifting platform 3 and the ball bearings 6 on the storage table 5, and combining the sequential tilting settings of each table top, so that the tray can automatically perform unidirectional displacement between the various mechanisms.

[0046] Compared with the prior art, the food vending machine provided by the present application has three major mechanisms of heating, conveying and storage, wherein the heating mechanism 100 is provided with a heating device 1, which can heat and cook the food workpieces placed on the support table 2. The storage mechanism 300 has more than two storage tables 5, and each storage table 5 is arranged up and down, which can effectively save storage space and is conducive to the allocation and storage of food workpieces, thereby realizing automated storage management. The conveying mechanism 200 has a lifting platform 3, and can move up and down to switch the height, so as to distribute the received food workpieces to each storage table 5, thereby forming a multifunctional integrated automated equipment for food heating and cooking, food sorting, and allocation and storage.

[0047] In addition, for the horizontal position transfer operation of food workpieces between various mechanisms, compared with the commonly used conveyor belts in the prior art, the vending machine of the present application is respectively provided with balls 6 that can allow food workpieces to slide on the upper surfaces of the support platform 2, the lifting platform 3 and the storage platform 5, and the support platform 2, the lifting platform 3 and the storage platform 5 are tilted in the same direction in sequence. After the food is cooked, the user can operate the machine to tilt the support platform 2 toward the lifting platform 3, so that the food slides onto the lifting platform 3 under the action of gravity, and is distributed to each storage platform 5 through the lifting platform 3, thereby realizing the automatic position transfer operation of the food workpiece, without applying a driving force or manual operation, effectively saving labor costs and equipment energy consumption, and improving the automation performance of the equipment. In this way, since there is no need to set up a conveyor belt, it can effectively avoid being easily affected by the oil stains generated by cooking in the machine when using the conveyor belt, which is convenient to clean, stable in operation and not easy to get stuck; and it can save the occupied space inside the machine and reduce the counterweight, so as to facilitate the transfer of the machine to the selling location, and effectively improve the user experience.

[0048] In another embodiment of the present application, the heating mechanism 100 is optimized. Figure 1 , Figure 3 and Figure 4 The heating mechanism 100 includes a container 101 for accommodating the support platform 2 and the heating device 1, and the container 101 is provided with an output port 102 for discharging materials to the conveying mechanism 200; the heating mechanism 100 also includes a driving cylinder 7 located at the bottom of the container 101, and the driving cylinder 7 is connected to a pull rod 71, and the pull rod 71 is connected to one side of the support platform 2 located at the output port 102. Please refer to Figure 6 and Figure 7 The container 101 is provided with a first rotating shaft 20 at the bottom of the support platform 2, and the middle of the support platform 2 is provided with a first connecting ear 21 that is sleeved with the first rotating shaft 20. The two ends of the first rotating shaft 20 are fixed to the inner wall hangers of the container 101. The driving cylinder 7 can drive the pull rod 71 to move downward, so that the support platform 2 is tilted on the lifting platform 3 with the first rotating shaft 20 as the axis. The middle of the support platform 2 is sleeved with the first rotating shaft 20 through the first connecting ear 21, so that the support platform 2 can be flipped horizontally.

[0049] During the heating and cooking process, the pull rod 71 can support one side of the support platform 2 so that the support platform 2 can maintain a horizontal state, so that the heating device 1 in the container 101 can heat and cook the food on the support platform 2. When the food is cooked, the driving cylinder 7 is activated to drive the pull rod 71 downward, so that the support platform 2 is horizontally turned and tilted toward the lifting platform 3. Under the action of gravity and the ball 6 on the support platform 2, the food slides from the support platform 2 to the lifting platform 3, effectively realizing the automatic discharging operation.

[0050] The outlet 102 of the container 101 may preferably be provided with an outlet door, which is used to be closed during the heating process of the heating mechanism 100 and opened after cooking to realize the outlet operation. Alternatively, a hanging plate is provided at one end of the lifting platform 3 close to the outlet 102 to cover the outlet 102, which is not specifically limited here.

[0051] See also Figure 3 , a workpiece input port 103 is provided on one side of the container 101. In actual applications, due to the small area of ​​the input port 103, it is difficult to set a guide device that can drive the food workpiece. Generally, the food workpiece needs to be put into the container 101 manually or by using tools. However, when the machine is in working state, the container 101 maintains a high temperature state, which can easily cause damage to the human body. Therefore, a guide platform 104 is provided between the input port 103 and the support platform 2, and the guide platform 104 is inclined toward the support platform 2. The user only needs to place the food on the guide platform 104, and under the action of gravity, the food can slide to the support platform 2 along the guide platform 104, thereby realizing automatic feeding operation, effectively eliminating safety hazards, and improving feeding efficiency.

[0052] See also Figure 3 , a fan 105 capable of generating airflow is provided in the container 101, and the fan 105 is arranged on a side symmetrical to the inlet 103, and the support platform 2 is inclined to one side of the fan 105. The fan 105 arranged in the container 101 is used to increase the flow rate and coverage of the high-temperature airflow in the container 101, so that the food is heated more evenly, and the heating speed and cooking effect are effectively improved. In addition, the support platform 2 is inclined to one side of the fan 105, so that after the food enters the container 101 through the inlet 103, it is concentrated inside the container 101 under the action of the balls 6 on the support platform 2 and gravity, so that the food can be evenly placed on the support platform 2, effectively increasing the capacity of the support platform 2, which is more conducive to evenly heating the food, thereby improving the cooking effect.

[0053] The heating device 1 includes an upper heating ring 11 and a lower heating ring 12, and the support platform 2 is located between the upper heating ring 11 and the lower heating ring 12. The upper heating ring 11 is provided above the support platform 2, and the lower heating ring 12 is provided below the support platform 2, thereby forming an upper and lower heating structure, so that food can be heated from the upper and lower sides of the support platform 2, so that the food is heated more evenly, the cooking effect is effectively improved, and the internal space of the container 101 can be maximized to improve the heating and cooking efficiency. In addition, the upper heating ring 11 and the lower heating ring 12 are respectively connected to a temperature control device (not shown in the figure) to control the upper heating ring 11 and the lower heating ring 12 respectively, effectively improving the heating performance and safety.

[0054] In another embodiment of the present application, the installation structure of the ball 6 is optimized. For setting the ball 6 on the support platform 2, please refer to Figure 4 The support platform 2 is provided with a plurality of nuts 22, which are radially arranged on the support platform 2; a grid 23 is provided on the support platform 2 that passes through the upper and lower surfaces of the support platform 2, and a nut 22 is provided in the grid 23; each nut 22 is provided with a top cap 221, and a mounting groove (not shown) for mounting a ball 6 is provided on the top cap 221 of the nut 22. The ball 6 is arranged using the top cap 221 on the nut 22, and the plurality of nuts 22 are evenly distributed on the support platform 2, which is conducive to the sliding of the food workpiece.

[0055] Among them, a grid 23 capable of installing a nut 22 is provided on the support platform 2. On the one hand, it is beneficial for the heat generated by the lower heating ring 12 at the bottom of the support platform 2 to pass through the grid 23 and rise to the upper surface of the support platform 2, thereby improving the heat transfer effect; on the other hand, the grid 23 simultaneously discharges food oil stains during the cooking process to the bottom of the container 101, and prevents the food and oil stains from flowing to the lifting platform 3 together when the support platform 2 is tilted to discharge the material, thereby effectively reducing the influence of oil stains during the cooking process on the product, and reducing the sanitary impact on the inner cavity of other mechanisms.

[0056] The guide platform 104 , the lifting platform 3 and the storage platform 5 are provided with a plurality of mounting holes 61 for mounting the ball 6 , and a mounting box 62 for fixing the ball 6 is provided at the bottom of the mounting hole 61 .

[0057] Take storage table 5 as an example, please refer to Figure 5 The upper surface of the storage platform 5 is provided with a plurality of mounting holes 61, and each mounting hole 61 is provided with a ball 6; see Figure 6 The lower surface of the storage table 5 is provided with mounting boxes 62 corresponding to each mounting hole 61.

[0058] Thus, the upper surfaces of the guide platform 104, the lifting platform 3 and the storage platform 5 are respectively provided with a plurality of balls 6, and the balls 6 are evenly distributed on each surface. In addition, in order to allow each ball 6 to operate independently, a mounting box 62 is provided below the mounting hole 61 on each surface, and the mounting box 62 is used to accommodate and cover the balls 6, effectively preventing foreign objects from penetrating and causing the balls 6 to get stuck, so that the balls 6 can maintain smooth operation and improve the sliding efficiency of the food workpiece.

[0059] The upper surfaces of the guide platform 104 and the lifting platform 3 are respectively provided with bosses 63 arranged around the periphery of the mounting hole 61. Figure 7 The upper surface of the lifting platform 3 is provided with a boss 63 located at the periphery of each mounting hole 61 (which cannot be shown because it is blocked by the boss 63).

[0060] The boss 63 is used to support the food workpieces sliding on each table surface, so that the bottom of the food workpiece is isolated from the table surface, effectively reducing the adhesion of the food workpiece to the table surface, avoiding the jamming of the food workpiece position transfer, and improving the smoothness of sliding.

[0061] In another embodiment of the present application, the structure of the transmission mechanism 200 is optimized. Figure 2 and Figure 7 The conveying mechanism 200 also includes a guide assembly 30 connected to both sides of the lifting platform 3. The bottom of the lifting platform 3 is provided with a driving motor 4. The guide assembly 30 includes a screw rod 31 and a slider 32. The slider 32 is fixedly connected to the lifting platform 3 and slides on the screw rod 31 as the driving motor 4 drives the lifting platform 3 to move up and down. The guide assembly 30 is used to stably guide the up and down displacement of the lifting platform 3 to prevent the lifting platform 3 from easily tipping over during the displacement process, which causes the food workpiece on the lifting platform 3 to slide and deviate. The lifting platform 3 can accurately guide the food workpiece to the corresponding storage platform 5, effectively improving the up and down displacement stability of the lifting platform 3.

[0062] In another embodiment of the present application, the structure of the storage mechanism 300 is optimized. Figure 8 , Fig. 9 and Fig.10 The storage mechanism 300 further includes a door panel 301, on which at least two access ports 302 corresponding to the positions of the storage platform 5 are provided; a receiving pocket 303 capable of supporting workpieces is provided on the outside of the door panel 301, and the receiving pocket 303 is connected to the access port 302; the storage mechanism 300 further includes a trigger rod 51, a second rotating shaft 52 and a third rotating shaft 53 located at the bottom of each storage platform 5, and the ends of the shaft bodies of the second rotating shaft 52 and the third rotating shaft 53 can be fixed to the inner cavity hanging part of the storage mechanism 300 respectively. A second connecting ear 54 is provided in the middle of the storage platform 5 to be sleeved with the second rotating shaft 52, and the storage platform 5 can be horizontally turned around the second rotating shaft 52; a guide hole 55 extending toward the access port 302 is provided on one end of the storage platform 5 close to the receiving pocket 303, and the guide hole 55 can preferably be a long hole that can be connected to the end of the trigger rod 51. The trigger rod 51 is fixed on the third rotating shaft 53, and one end of the trigger rod 51 passes through the guide hole 55 and extends to the upper surface of the lifting platform 3, and the other end of the trigger rod 51 is provided with a hook 511; one end of the storage platform 5 is provided with a closing arc plate 56 that can cover the taking-out port 302, and the lower edge of the closing arc plate 56 is buckled with the hook 511 of the trigger rod 51.

[0063] The working principle of the storage mechanism 300 is as follows: when the storage platform 5 receives a food workpiece, the front end of the food workpiece hits the end of the trigger rod 51 exposed on the storage platform 5, so that the trigger rod 51 rotates along the guide hole 55 with the third rotating shaft 53 as the axis, so that the hook 511 on the other end of the trigger rod 51 is separated from the door-closing arc plate 56. At the same time, after the food workpiece hits the trigger rod 51, the food workpiece slides from the input end of the storage platform 5 to the output end of the storage platform 5, and because the storage platform 5 itself is inclined, the gravity of the storage platform 5 is transferred to the output end, so that the storage platform 5 is horizontally flipped, and the door-closing arc plate 56 moves downward to open the access port 302. At this time, the food workpiece can smoothly pass through the access port 302 from the storage platform 5 and slide to the receiving pocket 303 outside the door panel 301, so that the user or customer can take it. When the food piece slides to the receiving pocket 303, the weight on the storage platform 5 changes, so the storage platform 5 and the trigger rod 51 are reset, so that the door-closing arc plate 56 moves up and blocks the taking-out port 302, and the hook 511 of the trigger rod 51 is locked and fixed with the lower edge of the door-closing arc plate 56. In this way, an automatic door opening structure is formed on the storage mechanism 300, and the material discharging operation is automatically completed without manual intervention, effectively improving the automation performance of the machine.

[0064] Please also read Figure 8 , Fig. 9 and Fig.10 The storage platform 5 is hinged with a baffle 57 extending downward at one end close to the lifting platform 3, and the baffle 57 has a weight. On the one hand, the baffle 57 with a weight is used to balance the storage platform 5 in an inclined state. On the other hand, the baffle 57 can block the food workpieces on the lifting platform 3 to prevent the food workpieces from sliding out at will. After the lifting platform 3 moves up and down to a corresponding height, the food is allowed to slide out to the storage platform 5 at the corresponding height.

[0065] Please also refer to Figure 7 , Fig. 9 and Fig.10 The lifting platform 3 is provided with a downwardly extending baffle 33 at one end close to the storage platform 5, and a flange 331 is provided at the lower edge of the baffle 33. The baffle 33 is guided and matched with the baffle plate 57 of the storage platform 5, so that the lifting platform 3 can smoothly move up and down between the storage platforms 5 at various heights, effectively avoiding mutual interference and jamming.

[0066] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
