AI Technical Summary
Existing boxed meal vending machines suffer from problems such as uneven heating of boxed meals, short shelf life, and inaccurate dispensing. In particular, the conveyor belt conveyor cannot accurately control the thrust, resulting in uneven storage and dispensing of boxed meals. Furthermore, they are complex in structure and expensive.
The system employs a tracked cargo channel combined with a support mechanism. The lifting and lowering of the support components are controlled by positioning components and electromagnets. Photoelectric sensors are used to precisely control the feeding position of the boxed meals, ensuring that the boxed meals are placed at an angle and discharged individually in a directional manner. The precise feeding of the boxed meals is achieved by using electromagnets to attract and move the support components downward.
It enabled smooth delivery of boxed meals, ensured uniform heating and shelf life, improved the accuracy and convenience of ingredient feeding, and reduced the complexity and cost of the equipment.

TECHNICAL FIELD
[0001] The utility model relates to lunch box machine technical field, concretely point to a kind of conveying device for heating type lunch box machine. BACKGROUND
[0002] The vending machine is a kind of sales mode that is not limited by time and place, saves manpower and is convenient for transaction. Common vending machines are divided into four types: beverage vending machine, food vending machine, comprehensive vending machine and cosmetic vending machine. With the acceleration of life rhythm, the vending machine for selling lunch boxes, also known as lunch box machine, is gradually widely used, which can enable general staff, especially white-collar class, to quickly complete dining in a short lunch time.
[0003] The lunch box machine is different from the vending machine for selling beverages and general packaged food, and has problems of heating and keeping warm, shelf life and damage of lunch boxes. Existing vending machines mainly include intelligent vending machine, snake-shaped or curved channel vending machine, spring drawer type vending machine and straight-line stacking type vending machine. The intelligent vending machine can open the cabinet door to randomly select by scanning code, but for lunch boxes which need to be kept at constant temperature and have a short shelf life, repeated opening and closing of the cabinet door will cause the temperature in the cabinet to decrease and not meet the requirements, so that the product storage and sales requirements cannot be guaranteed, and the product is also easily reduced in shelf life due to the repeated opening and closing of the door. The channel of the snake-shaped or curved channel vending machine is a curved metal cavity, which is not suitable for lunch boxes with large size, and the product is discharged one by one like a clip, relying on the gravity of the product to slide down from top to bottom, which is not conducive to the dispersion of hot air, cannot guarantee the constant temperature control of all lunch boxes, and has a complex structure, small application range and high equipment price. The spring drawer type vending machine uses a spring spiral channel to push beverages or food forward, but this spiral channel cannot push lunch boxes with rectangular structure, and the direct dropping of materials from top to bottom is easy to cause the lunch boxes with film-shaped packaging to be damaged and leaked due to impact. The products of the straight-line stacking type vending machine are stacked together, which is easy to cause the lunch boxes around to be quickly heated, while the lunch boxes in the middle area are slowly heated and unevenly heated, so that it cannot be ensured that all lunch boxes are in the same constant temperature state, which is easy to cause the heating quality of lunch boxes to be different. Therefore, the existing vending machine is only suitable for beverages, snacks and other packaged food, and even if a heating system is added, it cannot completely meet the requirements of automatic selling of lunch boxes, which is very tricky. Therefore, the current belt channel combined with a push plate to push the material is more suitable for storing and discharging lunch boxes with square or cylindrical structure, but the required pushing force is different due to the different number of stacked lunch boxes, so the size of the pushing force cannot be accurately set, and the discharging cannot be accurately controlled, and the problem of uneven heating of the stack also exists, and the corresponding partition plate arranged between each lunch box will inhibit the pushing action, so that it cannot be practically solved.
[0004] Therefore, the research purpose of the utility model is to provide a conveying device for a heated lunch box machine, which can ensure smooth delivery of lunch boxes, store and drive the lunch boxes through a track, isolate and store the lunch boxes through a supporting mechanism, control the stable support and single directional delivery of the lunch boxes through the lifting characteristics of the supporting mechanism, and isolate adjacent lunch boxes to avoid stacking and sticking of the lunch boxes and affect the uniformity of heating, so as to ensure the shelf life.
