Description

TECHNICAL FIELD

[0001] The utility model relates to lunch box machine technical field, specifically point to a kind of lunch box machine shelf of constant temperature effect can be promoted. BACKGROUND

[0002] The vending machine is a kind of sales mode not being restricted by time, place, saving manpower and being convenient for transaction, and common vending machine is divided into four kinds: beverage vending machine, food vending machine, comprehensive vending machine, cosmetic vending machine. With the acceleration of life rhythm, vending lunch box vending machine, also known as lunch box machine, is slowly widely used, and can enable general staff, especially white-collar class, to quickly complete dining in short lunch time.

[0003] The lunch box machine is different from beverage and general packaged food vending machine, and there are problems of lunch box heating, shelf life and lunch box damage. Existing vending machine mainly includes intelligent vending machine, snake-shaped goods channel or curved goods channel vending machine, spring drawer type vending machine and straight-line stacking type vending machine. Among them, the intelligent vending machine can be randomly selected by opening the cabinet door through scanning code, but for lunch box, which needs to be stored at constant temperature and has a short storage period, repeatedly opening and closing the cabinet door will cause the temperature in the cabinet to decrease and not meet the requirements, so that the product storage and vending requirements cannot be guaranteed, and the product is also easily reduced in shelf life due to repeated opening and closing of the door. The goods channel of the snake-shaped goods channel or curved goods channel vending machine is a curved metal cavity, which is not suitable for larger lunch boxes, and its goods outlet mode is like a clip, one after another, relying on the gravity of the product to slide from top to bottom, and the product is stacked layer by layer, which is not conducive to the dispersion of hot air, and cannot guarantee the constant temperature control of all lunch boxes, and the structure is complex, the application range is small, and the equipment price is high. The spring drawer type vending machine uses spring spiral goods channel to push beverages or food forward, but this spiral goods channel cannot push the lunch box with rectangular structure, and the material directly falls from top to bottom, which is easy to cause the lunch box with film-shaped packaging to be damaged and leaked due to impact. The goods 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 the heating is uneven, 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 foods, and even if the heating system is increased, it cannot completely meet the requirements of automatic vending of lunch boxes, which is very tricky, so it is very important to change the storage and discharge structure of lunch boxes.

[0004] The current track goods channel combined with the pushing plate pushing material is more suitable for the box lunch with square or cylindrical structure to store and discharge, but the pushing force required is different due to the different number of stacked box lunches, so the size of the pushing force cannot be accurately set, thereby the discharging cannot be accurately controlled, and the problem of uneven heating of the stack also exists, and the corresponding partition plate arranged between the box lunches will inhibit the pushing material action, so that it cannot be practically solved.

[0005] Therefore, a box lunch machine shelf capable of improving the constant temperature effect is designed, which can effectively prevent the box lunches from being stacked and adhered by combining the track goods channel with the lifting support mechanism to isolate the adjacent box lunches, help the hot air to circulate in the entire shelf, thereby improve the uniformity of heating, ensure the constant temperature state of the box lunch storage, and ensure the shelf capable of improving the constant temperature effect.
