Description

Technical Field

[0001] The invention relates to the technical field of food vending machines, in particular to a food vending machine with a self-cleaning function. Background Art

[0002] The sesame seed cake vending machine is a food vending machine that integrates advanced existing technologies such as automation technology, Internet of Things technology and payment technology. The vending machine is mainly equipped with refrigerator cabinets, bag-tearing equipment, belt conveyors, microwave equipment, ovens, bagging equipment, delivery port elevators and other mechanical equipment to complete the processing and sales of sesame seed cakes. When processing sesame seed cakes, the bag-tearing equipment tears the bags of bagged sesame seed cakes in the refrigerator cabinet, and the unpacked sesame seed cakes slide along the slide board onto the conveyor belt of the belt conveyor. The conveyor belt transports the sesame seed cakes to the microwave equipment for heating and thawing, and then the sesame seed cakes are transported to the oven for baking, and finally transferred from the oven to the delivery port elevator station to present the processed sesame seed cakes to the user;

[0003] When the sesame seed cake is being transported by the slide plate and the conveyor belt, the food crumbs on the bottom surface of the sesame seed cake (the side in contact with the conveyor belt) will fall onto the conveyor belt. In order to prevent the accumulation of food crumbs on the conveyor belt and the slide plate and cause cross contamination, a brush roller is generally installed inside the vending machine to rotate and clean the conveyor belt and the slide plate. Although the brush roller can clean the food crumbs on the surface of the conveyor belt, it cannot clean the source of the food crumbs. For example, the food crumbs on the top surface of the sesame seed cake will not fall directly onto the conveyor belt. In the subsequent processing and transmission process, this part of the food crumbs will also be transferred to other workstation machinery and equipment. In addition, when the surface of the sesame seed cake is coated with edible oil, the conveyor belt adhered with grease cannot be cleaned by simply relying on the brush roller to clean the grease, thereby affecting the cleaning effect of the sesame seed cake vending machine. Summary of the invention

[0004] The object of the present invention is to provide a food vending machine with a self-cleaning function to solve the problems raised in the above background technology.

[0024] Furthermore, the conveyor also includes two driving rollers, two first limiting rollers and a second limiting roller. The two driving rollers, the two first limiting rollers and the second limiting roller are all drivingly connected to the conveyor belt. One driving roller rotates with a first baffle at both ends, and a third motor for driving the driving roller to rotate is fixed to the outside of one first baffle.

[0025] Furthermore, the intercepting mechanism also includes two connecting rods 2 both fixed to the slide plate, and the connecting rods 2 are slidably connected to the connecting rod 1 at the corresponding position.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The motor drives the skateboard to rotate 180 degrees so that the side of the skateboard that conveys the sesame cake can be rotated toward the cleaning mechanism. The motor 4 on one side of the moving seat of the cleaning mechanism drives the brush roller 1 to rotate the cleaning panel, so that the food debris adhering to the panel can be dropped into the receiving box for collection. The motor 2 drives the screw rod to rotate forward and reversely to drive the moving seat screwed with the screw rod to move linearly back and forth along the guide rail, so that the rotating brush roller 1 can move to different positions along the length direction of the skateboard to clean the skateboard, which is beneficial to the cleaning efficiency of the Gao skateboard.

[0031] 2. By extending one end of the conveyor belt to the inside of the receiving box, a plurality of connecting rods 1 are arranged on the bottom surface of one end of the slide plate, which are close to the surface of the conveyor belt. The motor 3 drives the transmission roller to rotate so that the conveyor belt is driven toward the receiving box (refer to the instruction manual). Figure 5 The conveyor belt is connected to the receiving box to receive the food residues on the conveyor belt, and the conveyor belt is connected to the receiving box to receive the food residues on the conveyor belt. The ...

[0032] 3. The output ends of the two electric push rods are contracted to press the shaft rod down and sink into the surface of the conveyor belt. One end of the pancake is transported to the top of the shaft rod along the conveyor belt. Then the output end of the electric push rod is extended to lift the pancake up (refer to the instruction manual). Fig.10), and the conveyor belt continues to transmit in the direction of the shaft rod, and the sesame seed cake lifted by the shaft rod can be turned over on the conveyor belt under the joint action of the static friction force given by the conveyor belt in the conveying direction, so that the previous top surface position of the sesame seed cake is converted to the bottom surface contacting the conveyor belt, and the sesame seed cake can be intercepted by the multiple connecting rods on the interception mechanism again, so that the conveyor belt passes on the bottom surface of the sesame seed cake, so as to clean the food debris on the surface of the conveyor belt and the top surface of the sesame seed cake at the source of the debris, thereby further improving the cleaning efficiency of the sesame seed cake vending machine, and to a certain extent, effectively preventing the food debris remaining on the sesame seed cake from being subsequently transferred to contaminate other processing stations.

[0033] 4. Extend the conveyor belt to the inside of the ultrasonic cleaning machine through two limit rollers 1 and 2. Inject a proper amount of cleaning liquid into the ultrasonic cleaning machine through the connecting pipe in advance. When the conveyor belt is transmitted to the cleaning liquid position inside the ultrasonic cleaning machine, the conveyor belt can be immersed in the cleaning liquid for ultrasonic cleaning, thereby fully cleaning the fine food debris on the conveyor belt while also cleaning the grease on the conveyor belt, which is beneficial to improving the cleaning effect of the conveyor belt.

[0034] 5. The shaft rod on the turning mechanism is used to lift the pancake and the conveyor belt is used to convey the pancake, giving it static friction so that the pancake can be turned over multiple times on the conveyor belt as needed. After each turning of the pancake, the oil tank can pump edible oil to the nozzle, so that the pancake transported to the bottom of the nozzle can be replenished with edible oil, which is convenient for baking the pancake later. Even if there is edible oil on the conveyor belt, the conveyor belt can be automatically cleaned when it is transported to the cleaning liquid position inside the ultrasonic cleaning machine. When the wet conveyor belt after cleaning is transported to the dryer position, the dryer can dry the conveyor belt for standby use. BRIEF DESCRIPTION OF THE DRAWINGS

An intercepting mechanism 700 is fixed to the bottom surface, and the intercepting mechanism 700 includes a crossbeam 710. A plurality of connecting rods 720 are embedded and fixed at equal intervals on one side of the crossbeam 710. A microwave device 800 fixedly connected to the cabinet 100 is arranged above the conveyor belt 640. The conveyor belt 640 passes through the microwave device 800. A turning mechanism 900 is arranged on the outer side of the middle part of the conveyor belt 640. The turning mechanism 900 includes two baffles 910 respectively arranged on both sides of the conveyor belt 640. The baffles 910 are fixed to the inner side of the cabinet 100. An electric push rod 920 is fixed to the outer side of the baffle 910. A shaft rod 921 is fixed between the output ends of the two electric push rods 920. The shaft rod 921 is used to lift one end of the pancake to turn it over.

[0048] Specifically, by arranging one end of the slide plate 200 and the conveyor belt 640 at the top of the receiving box 400, the cleaning mechanism 300 can clean the food debris on the surface of the slide plate 200 and collect it in the receiving box 400, and the conveyor belt 640 will also transport the food debris on its surface to the receiving box 400 during the transmission process, thereby automatically cleaning the food debris on the surface of the slide plate 200 and the conveyor belt 640. By arranging an interception mechanism 700 on the bottom surface of the slide plate 200, a plurality of connecting rods 720 on the interception mechanism 700 can intercept the sesame cake on the conveyor belt 640 so that it will not As the conveyor belt 640 moves, the conveyor belt 640 can clean up the debris on the contact surface side of the sesame cake and the conveyor belt 640 when passing through the sesame cake and put it into the receiving box 400. At the same time, the shaft 921 on the flipping mechanism 900 can lift up one end of the sesame cake with the help of the electric push rod 920, and the conveyor belt 640 can be driven under the sesame cake to make the sesame cake flip over on the conveyor belt 640, so that the intercepting mechanism 700 and the flipping mechanism 900 can cooperate to fully clean the food debris on the top and bottom surfaces of the sesame cake, which is convenient for automatic cleaning from the source of food debris, which is beneficial to improving the cleaning efficiency of the sesame cake vending machine.

[0049] like Figure 1 and Figure 3As shown in the figure, in this embodiment, the bag tearing device 120 tears the bag of baked sesame seed cakes conveyed from the top of the refrigerator 110. The baked sesame seed cakes after bag tearing are transferred to the conveyor belt 640 along with the sliding plate 200. The conveyor belt 640 drives to transfer the baked sesame seed cakes to the first inclined plate 130, and then slides down along the first inclined plate 130 into the oven 140. The baked sesame seed cakes after baking fall to the position of the second inclined plate 150 from the oven 140, and then are guided and conveyed to the position of the outfeed port elevator 160. The outfeed port elevator 160 transfers the baked sesame seed cakes to the position of the outfeed door panel 180. The user can open the outfeed door panel 180 to take out the baked sesame seed cakes. This part of the content is the basic working principle of the existing vending machine, and the related equipment involved in the above content is also the equipment and machinery that has been put into use in this field. The detailed working principle of the equipment will not be elaborated here.

[0050] As Figure 5 and Figure 7 As shown in the figure, in this embodiment, the position adjusting mechanism 210 includes a U-shaped frame 211 rotatably connected to the sliding plate 200. One end of the U-shaped frame 211 is fixed with a motor one 2111 for driving the sliding plate 200 to rotate. A first guide rail 212 is arranged on the outer side of the U-shaped frame 211. The U-shaped frame 211 is slidably connected to the first guide rail 212. A circular block is fixed on the outer side of the first guide rail 212, and a transmission shaft 213 is fixed on the outer side of the circular block. A circular seat 2131 is rotatably arranged on the outer side of the transmission shaft 213. The circular seat 2131 is fixed inside the cabinet 100. The circular seat 2131 improves the rotation stability of the transmission shaft 213. A first gear is sleeved and fixed on the outer side of the transmission shaft 213. A motor five is fixed inside the cabinet 100, and a second gear meshing with the first gear is fixed at the output end of the motor five.

[0051] In this embodiment, in the initial state, as Figure 8 shown, the U-shaped frame 211 inclines the sliding plate 200 towards the bag tearing device 120, which is convenient for receiving the baked sesame seed cakes falling from the bag tearing device 120. Then, the motor five drives the transmission shaft 213 to rotate through the meshing of the first gear and the second gear, and the first guide rail 212 drives the U-shaped frame 211 to rotate the sliding plate 200 to incline towards the conveyor belt 640, so that the baked sesame seed cakes on the surface of the sliding plate 200 can fall onto the conveyor belt 640 through the gap between the sliding plate 200 and the cross beam 710. Then, the motor one 2111 drives the sliding plate 200 inside the U-shaped frame 211 to rotate by 180 degrees, so that the food debris on the surface of the sliding plate 200 can rotate towards the receiving box 400, and the food debris can automatically fall into the receiving box 400.

[0052] In this embodiment, a slider 2112 slidably connected to the first guide rail 212 is fixed to one side of the U-shaped frame 211. The first guide rail 212 can not only drive the U-shaped frame 211 with the slide plate 200 to rotate to different positions to receive and release the sesame seed cakes through the slider 2112, but also enable the slider 2112 on the U-shaped frame 211 to slide along the first guide rail 212 to the end where the first guide rail 212 is inclined downward under the gravity of the slide plate 200 and the U-shaped frame 211 after the first guide rail 212 rotates and tilts. Thus, the slide plate 200 after the rotation changes direction can linearly move a certain distance on the first guide rail 212, realizing the movement of the slide plate 200 to different positions to receive and release the sesame seed cakes within a relatively small space of the cabinet 100.

[0053] As Figure 2 and Figure 6 shown, in this embodiment, a drawer box 410 is slidably connected to the inner bottom of the receiving box 400, and the drawer box 410 can be slid out from the rear of the cabinet 100, facilitating the cleaning of the food debris collected inside the receiving box 400.

[0054] As Figure 2 and Figure 4 shown, in this embodiment, a dryer 510 is fixed to one side of the ultrasonic cleaning machine 500. The dryer 510 is an existing technical device that can dry the conveyor belt 640 passing through its interior, enabling the conveyor belt 640 after water washing to be dried and ready for use. The specific working principle of the dryer 510 will not be elaborated here. Two connecting pipes 520 are fixedly connected and communicated to the outside of the ultrasonic cleaning machine 500. One of the two connecting pipes 520 conveys the cleaning liquid to the ultrasonic cleaning machine 500, and the other connecting pipe 520 sucks out the cleaning liquid, facilitating the replacement of the cleaning liquid for the ultrasonic cleaning machine 500.

[0055] As Fig. 9 shown, in this embodiment, another dryer 510 can be installed at the position of the dotted line B on the side of the ultrasonic cleaning machine 500 facing away from the dryer 510, so that the conveyor belt 640 can be dried regardless of the conveying direction.

[0056] As Figure 6 and Fig. 9 shown, in this embodiment, the conveyor 600 further includes two driving rollers 610, two first limiting rollers 620 and a second limiting roller 630. The two driving rollers 610, the two first limiting rollers 620 and the second limiting roller 630 are all drivingly connected to the conveyor belt 640. Baffles 650 are rotatably arranged at both ends of one driving roller 610. A motor 651 for driving the rotation of the driving roller 610 is fixed to the outside of one baffle 650. The baffle 650 is fixedly installed with the cabinet 100 and the microwave device 800.

[0057] In this embodiment, motor three 651 drives a drive roller 610 to rotate, so that the conveyor belt 640 is transmitted between two drive rollers 610, two limit rollers 1 620 and limit roller 2 630. After the sesame seed cake is placed on the conveyor belt 640, the conveyor belt 640 can be firstly transmitted in the direction of the receiving box 400, so as to facilitate the conveyor belt 640 and the residual food crumbs on the sesame seed cake to be transported to the inside of the receiving box 400. After the food crumbs are cleaned, the conveyor belt 640 can be transported in the direction of the microwave equipment 800, so as to facilitate the transfer of the sesame seed cake to the next processing station.

[0058] like Figure 8 As shown, in the present embodiment, the interception mechanism 700 further includes two connecting rods 730 both fixed to the slide plate 200, and the connecting rods 730 are slidably connected to the corresponding connecting rods 720. After the slide plate 200 rotates 180 degrees, a plurality of connecting rods 720 can contact the conveyor belt 640, so that the plurality of connecting rods 720 can intercept the pancakes. As the conveyor belt 640 is transmitted, the connecting rods 730 can slide with the corresponding connecting rods 720, so that the plurality of connecting rods 720 can be telescopically adjusted in length on the connecting rods 730, so that when the slide plate 200 rotates onto the conveyor belt 640 with the plurality of connecting rods 720, the connecting rods 720 can automatically adjust the length to prevent the conveyor belt 640 from interfering with the rotation of the slide plate 200 with the connecting rods 720. When the plurality of connecting rods 720 rotate to above the conveyor belt 640, the connecting rods 720 can fall down and stick to the conveyor belt 640 under the action of their own gravity, so as to facilitate the subsequent interception of pancakes.

[0059] like Figure 6 As shown, in this embodiment, an oil tank 810 is fixed on the top of the microwave device 800, and an oil spray nozzle 811 is fixed on the outside of the oil tank 810 through a pipeline. The oil tank 810 transports edible oil to the pipeline through an oil pump, and the edible oil is sprayed onto the sesame seed cake through the oil spray nozzle 811, so that edible oil can be added to the sesame seed cake as needed.

[0060] like Figure 4 and Fig.10 As shown, in the present embodiment, one end of the baffle plate 910 is fixedly connected to the microwave device 800, and a support block fixedly connected to the electric push rod 920 is fixed to the bottom of the baffle plate 910, so that the electric push rod 920 is fixed to the outside of the baffle plate 910, and the two electric push rods 920 cooperate to drive the shaft 921 to move up and down, so as to facilitate the flipping of the pancake, wherein a notch is provided at one end of the baffle plate 910, and the notch meets the space requirement for the slide plate 200 to rotate with the interception mechanism 700.

[0061] like Figure 1As shown, in this embodiment, a shipping door panel 180 is hinged on the outer side of the cabinet 100, and a touch screen 190 is installed on the outer side of the cabinet 100. Opening the shipping door panel 180 is convenient for taking out the sesame cakes, and the touch screen 190 is convenient for users to purchase sesame cakes by touch operation. This part is the existing technology and the specific content is not repeated here.

[0062] Embodiment 2 is based on Embodiment 1 and is designed to improve the effect of cleaning food debris on the surfaces of the slide plate 200 and the conveyor belt 640 .

[0063] like Figure 6 and Figure 7 As shown, in this embodiment, the cleaning mechanism 300 includes a guide rail 310 fixed to the cabinet 100, a screw rod 311 rotates inside the guide rail 310, and a movable seat 320 slidably connected to the guide rail 310 is screwed on the outer side of the screw rod 311, a brush roller 321 rotates on one side of the movable seat 320, and a brush roller 420 rotatably attached to the conveyor belt 640 is inside the receiving box 400.

[0064] Specifically, the motor 4 on the outside of the movable seat 320 drives the brush roller 1 321 to rotate and clean the surface of the slide plate 200, and the motor 2 312 drives the screw rod 311 to rotate so that the movable seat 320 moves linearly inside the guide rail 2 310, so that the rotating brush roller 1 321 can clean different positions on the surface of the slide plate 200, so that the food debris on the surface of the slide plate 200 can fall off quickly. Figure 4 As shown, one end of the shaft in the middle of the brush roller 2 420 and the driving roller 610 is sleeved with a gear 3 that meshes with each other, so that the rotation of the driving roller 610 will drive the brush roller 2 420 to rotate and clean the conveyor belt 640, so that food debris on the surface of the conveyor belt 640 can fall off quickly.

[0065] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
