Description

Technical Field

[0001] The utility model relates to the technical field of rice packaging equipment, and more specifically, to an automatic rice packaging machine which is convenient for disassembly and assembly and adjustment of the packaging amount. Background Art

[0002] With the accelerated pace of life, the existing catering industry, including schools, company canteens and catering companies, has paid more and more attention to fast food and favored it. So far, the processing and production of lunch boxes, the preparation, cleaning and cooking of dishes can all be completed by mechanical equipment. However, the subsequent rice packaging task still requires manual labor. Most domestic meal distribution companies rely on a large amount of labor and time costs to complete the rice distribution task. This will not only greatly increase production and management costs, but manual rice distribution will also cause problems such as inconsistent rice portions and food safety. With the continuous advancement of technological development and the increase in labor costs, equipment for rice packaging and transportation has emerged, but these equipment still have problems such as insufficient production speed and uneven product quality. Therefore, equipment with high production efficiency and strong adaptability can better meet the needs of meal distribution companies.

[0003] The patent documents of related devices retrieved are:

[0004] 1. CN219172814 U discloses a rice dispensing machine, comprising a frame, a box dropping mechanism, a lifting mechanism, a conveying mechanism and a rice dispensing mechanism. Rice is poured into a funnel above the rice dispensing mechanism through the lifting mechanism, and finally falls into a rice box through a rice loosener, a rice dispensing device and a rice outlet to complete the rice dispensing.

[0005] 2. CN114291311 A discloses a rice dispensing machine, comprising a lunch box, an automatic feeding mechanism, an automatic tableware dispensing mechanism, an automatic rice dispensing mechanism and a stepping conveying mechanism. The lunch boxes are dispensed into a stepping conveyor belt by the automatic tableware dispensing mechanism, the rice boxes are loaded into the automatic feeding mechanism, the rice is poured into a funnel above the automatic rice dispensing mechanism by the automatic feeding mechanism, and the rice is dispensed into the lunch boxes by the automatic rice dispensing mechanism.

[0006] 3. CN 210324367 U discloses an automatic rice-beating machine, which comprises a rice storage bin, a beating mechanism and a rice-dispensing mechanism. Rice is manually poured into an upper funnel, the rice is beating by the beating mechanism, and then the rice is dispensed into a meal box below by a rotating rice-dispensing mechanism. The rice-dispensing machine is suitable for dispensing meals in school or company canteens.

[0007] Most of the quantitative mechanisms in the rice dispensers in the prior art are driven by a single motor to drive two spur gears to move in opposite directions to achieve the purpose of driving two layers of plug plates at the same time. However, this ignores the fact that one layer of plug plates may not be completely closed while the other layer of plug plates has begun to open, causing rice to fall onto the conveyor belt and be difficult to clean, leading to food safety issues. Moreover, this mechanism requires the motor to rotate forward and reverse frequently, which seriously damages the motor.

[0008] Most of the rice dispensers in the prior art are of an integral vertical funnel type. Although the lateral space occupied is reduced, it is easy for the rice to continue to pile up after being scattered, resulting in the rice sticking to the rice dispenser mechanism for the second time, blocking the rice outlet and making it difficult to clean.

[0009] The rice dispenser in the prior art has high requirements on the conveyor belt of the rice distribution workshop. It is necessary to adjust the specifications of the existing conveyor belt in the workshop to cooperate with the conveyor belt of the rice dispenser, and the step-by-step conveyor belt is more expensive.

[0010] The rice dispenser in the prior art does not have a leftover rice export function and cannot detect the leftover rice, and requires manual assistance, which increases the labor cost.

[0011] Finally, most rice dispensers cannot adjust the amount of rice according to the different lunch boxes. Utility Model Content

[0077] In combination with the above structural description, the working principle of the automatic rice dispensing machine of the utility model, which is easy to disassemble and adjust the dispensing amount, is described below. Specifically:

[0078] S1. The user presses the machine start button, and the hollow motor 104 of the rice evenly distributing mechanism 100 starts to rotate, and four rice loosening columns facing each other break up the rice.

[0079] S2. After 10 seconds, the rice transport mechanism 200 starts to operate, and transports the evenly distributed rice to the quantitative adjustment packaging mechanism 400.

[0080] S3. At this time, the user can change the thickness of the rice output by the rice evenly distributing mechanism 100 by adjusting the output amount adjusting device 103, and change the width of the rice output by the rice evenly distributing mechanism 100 by adjusting the distance between the conveyor belt guards 202 on both sides.

[0081] S4. When the rice passes through the rice quantity detection device 300 at the front end of the rice transport mechanism 200, the timing starts. The rice quantity detection device 300 keeps detecting that rice passes through and the time is 3 seconds as one cycle.

[0082] S5. The initial state of the quantitative adjustment and packaging mechanism 400 is that the upper quantitative plug plate 402 is open and the lower quantitative plug plate 404 is closed. After the rice enters the quantitative adjustment and packaging mechanism 400, the upper quantitative plug plate 402 is closed and the lower quantitative plug plate 404 is opened after 3 seconds, and the rice leaks into the lunch box below the quantitative adjustment and packaging mechanism 400. Then the lower quantitative plug plate 404 is closed and the upper quantitative plug plate 402 is opened, completing a cycle.

[0083] S6. Repeat the above cycle until the rice amount detection device 300 at the front end of the rice transport mechanism 200 detects no rice within 10 seconds, then all devices are reset to remind the user to add rice, repeat the above cycle, or click "Complete Task" to end the work.

[0088] 3. The thickness of the rice output by the rice distribution mechanism can be changed by adjusting the output adjustment device, and the width of the rice output by the rice distribution mechanism can be changed by adjusting the distance between the protective covers of the conveyor belts on both sides. It can well meet different production needs.

[0090] 5. The upper quantitative plug plate and the lower quantitative plug plate in the quantitative adjustment filling mechanism are driven by a set of crank slider mechanisms respectively.
