Description

TECHNICAL FIELD

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

[0002] The bun vending machine is a food vending machine integrating advanced existing technologies such as automation technology, Internet of Things technology and payment technology. The internal vending machine is mainly installed with refrigerator cabinet, bag tearing device, belt conveyor, microwave device, oven, bagging device, delivery port elevator and other mechanical devices to cooperatively complete the processing and vending of buns. During bun processing, the bag tearing device tears the bagged buns in the refrigerator cabinet, and the bagged buns fall along the slide plate to the conveyor belt of the belt conveyor. The conveyor belt conveys the buns into the microwave device for heating and thawing, and then the buns are conveyed into the oven for baking, and finally the processed buns are presented to the user from the oven to the delivery port elevator station.

[0003] During the conveying process of the buns through the slide plate and the conveyor belt, food debris on the bottom surface of the buns (the side surface in contact with the conveyor belt) will fall onto the conveyor belt. In order to prevent cross contamination caused by accumulation of food debris on the conveyor belt and the slide plate, 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 debris on the surface of the conveyor belt, it cannot clean from the source of the food debris. For example, the food debris on the top surface of the buns will not directly fall onto the conveyor belt, and during the subsequent processing and conveying process, this part of the food debris will be transferred and left on other mechanical devices. In addition, when the surface of the buns is coated with edible oil, the conveyor belt with oil adhered to it cannot be cleaned by the brush roller alone, thereby affecting the cleaning effect of the bun vending machine. SUMMARY

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

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0008] A cleaning mechanism is fixed below the slide plate for cleaning the food debris on the surface of the slide plate.

[0009] A receiving box is fixed inside the cabinet for receiving the impurities falling from the slide plate.

[0010] An ultrasonic cleaning machine is fixed in the cabinet;

[0011] A conveyor is arranged between the receiving box and the ultrasonic cleaning machine, and is used for conveying the sesame cakes falling from the slide plate, and the conveyor comprises a conveying belt;

[0012] An intercepting mechanism is fixed to the bottom surface of one end of the slide plate, and the intercepting mechanism comprises a cross beam, and a plurality of connecting rods are embedded and fixed to one side of the cross beam at equal intervals;

[0013] A microwave device is fixed above the conveying belt, and is used for thawing and preheating the sesame cakes;

[0014] A turnover mechanism is used for turning over the sesame cakes, and the turnover mechanism comprises two baffle plates two arranged on the two sides of the conveying belt respectively, and electric push rods are fixed to the outer sides of the baffle plates two, and a shaft rod is fixed between the output ends of the two electric push rods.

[0015] Further, the positioning mechanism comprises:

[0016] A U-shaped frame is rotationally connected with the slide plate, and one end of the U-shaped frame is fixed with a motor one used for driving the slide plate to rotate;

[0017] A guide rail one is slidingly connected with the U-shaped frame, and a circular block is fixed to the outer side of the guide rail one;

[0018] A transmission shaft is fixedly connected with the circular block.

[0019] Further, the cleaning mechanism comprises:

[0020] A guide rail two is fixed in the cabinet, and a lead screw is rotationally arranged in the guide rail two;

[0021] A moving seat is screw-coupled with the lead screw, and a brush roller one is rotationally arranged on one side of the moving seat.

[0022] Further, the receiving box is rotationally arranged with a brush roller two abutting against the conveying belt, and a drawer box is slidingly connected to the inner bottom of the receiving box.

[0023] Further, the ultrasonic cleaning machine is fixed with a drying machine on one side, and the ultrasonic cleaning machine is fixedly connected with two connecting pipes on the outer side.

[0024] Further, the conveyor further comprises two transmission rollers, two limiting rollers one and a limiting roller two, and the two transmission rollers, the two limiting rollers one and the limiting roller two are all drivingly connected with the conveying belt, and the two ends of one of the transmission rollers are rotationally arranged with baffle plates one, and the outer side of one of the baffle plates one is fixed with a motor three used for driving the transmission roller to rotate.

[0025] Furthermore, the interception mechanism also includes two connecting rods two of which are fixed to the sliding plate, and the connecting rods two of which are slidably connected to the corresponding connecting rod one.

[0026] Furthermore, an oil tank is fixed to the top of the microwave device, and an oil nozzle is fixed to the outside of the oil tank via a pipe.

[0027] Furthermore, one end of the second baffle is fixedly connected to the microwave equipment, and a support block fixedly connected to the electric push rod is fixed at the bottom of the second baffle.

[0028] Furthermore, the cabinet has a hinged loading door panel on its outer side and a touch screen installed on its outer side.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. The motor drives the slide plate to rotate 180 degrees, allowing the side of the slide plate that transports the sesame cakes to rotate towards the cleaning mechanism. The four-wheel drive motor on one side of the cleaning mechanism's moving seat causes the first brush roller to rotate and clean the panel, making it easy for food crumbs adhering to the panel to fall into the collection box for collection. The second motor drives the lead screw to rotate forward and backward, which drives the moving seat that is screwed to the lead screw to move back and forth linearly along the guide rail. This allows the rotating first brush roller to move to different positions along the length of the slide plate to clean the slide plate, which is beneficial to the cleaning efficiency of the Tigao slide plate.

[0031] 2. By extending one end of the conveyor belt into the receiving box, multiple connecting rods are installed on the bottom surface of one end of the slide plate, which are in contact with the surface of the conveyor belt. The three-wheel drive motor rotates the drive roller, causing the conveyor belt to move towards the receiving box (refer to the instruction manual). Figure 5 (Indicated by the direction of the middle arrow), so that food residues remaining on the surface of the conveyor belt can fall into the receiving box and be collected as the conveyor belt travels to the top of the receiving box. Multiple connecting rods that contact the conveyor belt can intercept the sesame cakes to prevent them from being transported into the receiving box. At the same time, the conveyor belt slides over the bottom of the sesame cakes, which can also clean up the food scraps on the bottom of the sesame cakes. By cleaning the food scraps on the surface of the conveyor belt, the machine can also clean up the scraps on the bottom of the sesame cakes, which is the source of the scraps, thus improving the cleaning efficiency of the sesame cake vending machine.

[0032] 3. The retraction of the output ends of the two electric actuators causes the shaft to press down and sink into the surface of the conveyor belt. One end of the sesame cake is conveyed to the top of the shaft by the conveyor belt. Then, the output ends of the electric actuators extend, causing the shaft to lift the sesame cake upwards (refer to the instruction manual). Figure 10), and the conveying belt continues to drive in the direction of the shaft rod. The baked cake lifted by the shaft rod can be turned over on the conveying belt under the joint action of the static friction force imparted by the conveying belt to the baked cake conveying direction, so that the top surface of the baked cake before being turned over is converted into the bottom surface in contact with the conveying belt. The baked cake can be intercepted again by the multiple connecting rods on the interception mechanism, so that the conveying belt passes through the bottom surface of the baked cake. The food debris on the surface of the conveying belt is cleaned at the same time, and the food debris on the top surface of the baked cake is also cleaned, thereby further improving the cleaning efficiency of the baked cake vending machine. To some extent, the subsequent transfer of the food debris remaining on the baked cake to other processing stations is effectively prevented.

[0033] 4. The conveying belt is extended and conveyed into the ultrasonic cleaning machine by two limiting rollers, i.e. limiting roller one and limiting roller two. A suitable amount of cleaning liquid is injected into the ultrasonic cleaning machine in advance through the connecting pipe. When the conveying belt is driven to the position of the cleaning liquid in the ultrasonic cleaning machine, the conveying belt can be soaked in the cleaning liquid for ultrasonic cleaning, so as to clean the fine food debris on the conveying belt and clean the oil on the conveying belt, thereby improving the cleaning effect of the conveying belt.

[0034] 5. The baked cake is lifted by the shaft rod on the turnover mechanism to impart static friction to the baked cake conveyed by the conveying belt, so that the baked cake can be turned over on the conveying belt as needed. After the baked cake is turned over once, the oil tank can pump edible oil to the oil injection nozzle, so that the baked cake conveyed below the oil injection nozzle can be supplemented with edible oil. The residual edible oil on the conveying belt can be automatically cleaned by the cleaning machine when the conveying belt is conveyed to the position of the cleaning liquid in the ultrasonic cleaning machine. After cleaning, the wet conveying belt can be dried by the drying machine for standby use. BRIEF DESCRIPTION OF DRAWINGS
