Technical Field

[0001] The utility model relates to the technical field of popcorn, in particular to a quantitative corn dispensing mechanism for a popcorn vending machine. Background Art

[0002] Popcorn is a kind of puffed food made by putting corn, oil and sugar into a popcorn machine. The sweetness and crispness of popcorn have won everyone's praise, especially in cinemas, supermarkets and food courts, and they are very popular with customers. The introduction of self-service popcorn machines allows consumers to quickly taste popcorn in different environments. In the information age, improving the automation level of machines and reducing manpower expenditures have also become new demands. In existing popcorn vending machines, the way to take corn is mostly to set a rotating feeding wheel under the corn barrel discharge port. The feeding wheel interface rotates to the corn barrel discharge port. After the feeding wheel is full of corn, it will turn to another discharge port. Since the feeding wheel, corn and corn barrel discharge port are all rigid materials, it is easy to get stuck, causing machine failure. Utility Model Content

[0022] The metering wheel 6 is a cylindrical structure, and has three evenly distributed corn metering grooves 61 in the cylindrical structure. The corn metering groove 61 is a fan-shaped cavity with an upper opening, and the bottom surface 63 of the fan-shaped cavity is an inclined surface. A feed port three 62 is provided on the bottom surface 63 of the corn metering groove 61, and the feed port three 62 is located at the bottom of the inclined surface.

[0023] A rotating shaft hole 64 is provided in the middle of the quantitative wheel 6, and a rotating shaft 10 is installed on the rotating shaft hole 64. Pulleys 14 are installed on the lower part of the rotating shaft 10 and the motor 13. The motor 13 drives the rotating shaft 10 to rotate through the pulley, and the rotating shaft 10 drives the quantitative wheel 6 to rotate together. A plurality of elastic sheets 52 are evenly distributed in the cylindrical cavity of the quantitative wheel cover plate 5. A bearing mounting hole is provided at the center of the quantitative wheel cover plate 5. A bearing 11 is installed in the bearing mounting hole, and the upper end of the rotating shaft is mounted on this bearing 11.

[0024] The number of the elastic sheets 52 is at least four.

[0025] The elastic sheet 52 divides the cylindrical cavity of the metering wheel cover plate 5 into a plurality of sector-shaped buffer grooves 53 , and the second feed port 51 is located in one of the buffer grooves 53 .

[0026] The depth of the buffer groove 53 is not less than 10 mm.

[0027] The distances between the feed port 3 62 and the feed guide port 9 and the rotating shaft 10 are the same.

[0028] In practical application, the working principle and process are as follows: a quantitative feeding device for popcorn equipment, a corn bin 1 is filled with corn kernels, when making popcorn, the corn kernels in the corn bin 1 fall through the discharge port 4 into the corn quantitative slot 61 provided on the quantitative turntable, and a sensor 12 is provided at the lower part of the quantitative wheel housing 8 for sensing the position of the corn quantitative slot 61.

[0029] After the corn quantitative trough 61 is filled with corn, the motor 13 drives the pulley 14 to make the rotating shaft 10 drive the corn quantitative trough 61 to rotate until the sensor 2 12 stops, completing one feeding. During the rotation process, the opening of the corn quantitative trough 61 is supported by the bottom surface of the quantitative wheel 6 shell, and the corn will not leave the corn quantitative trough 61. At the same time, the quantitative wheel cover 5 is provided with an elastic sheet 52, which will level the corn in the corn quantitative trough 61 so that the quantitative wheel 6 can rotate smoothly, which can not only avoid the corn and the discharge port of the corn bin 1 from getting stuck, but also ensure that the amount of corn falling each time is the amount of corn in the corn quantitative trough 61, thereby achieving quantitative feeding. The corn bin 1 is provided with a first sensor 2 for detecting the amount of material in the corn bin 1, and reminding to add material in time, so that the quantitative wheel 6 will not idle. Through volume measurement, the measurement is accurate, will not affect the customer's visual experience, and the amount of popcorn in each bucket is consistent, while also ensuring the structural stability of the machine each time taking corn.

[0030] A rotating shaft hole 64 is provided in the middle of the quantitative wheel 6, and a rotating shaft 10 is installed on the rotating shaft hole 64. Pulleys 14 are installed on the lower part of the rotating shaft 10 and the motor 13. The motor 13 drives the rotating shaft 10 to rotate through the pulley, and the rotating shaft 10 drives the quantitative wheel 6 to rotate together. A plurality of elastic sheets 52 are evenly distributed in the cylindrical cavity of the quantitative wheel cover plate 5. A bearing mounting hole is provided at the center of the quantitative wheel cover plate 5. A bearing 11 is installed in the bearing mounting hole, and the upper end of the rotating shaft is mounted on this bearing 11.

[0031] The elastic sheet 52 divides the cylindrical cavity of the metering wheel cover plate 5 into a plurality of fan-shaped buffer grooves 53, and the second feed port 51 is located in one of the buffer grooves 53, and the depth of the buffer groove 53 is not less than 10 mm. Therefore, the elastic sheet 52 can scrape off the excess corn in the corn metering groove 61 and store it in the buffer groove 53. Because of the action of the elastic sheet 52 and the buffer groove 53, the corn kernels will not be stuck between the metering wheel cover plate 5 and the metering wheel disc 6.

[0032] The above-mentioned specific implementation modes are preferred embodiments of the present invention and cannot be used to limit the present invention.
