Description

Self-service rice maker

technical field

The utility model relates to a self-service rice maker.

Background technique

In recent years, with the acceleration of the pace of life, people's concept of time has become more and more obvious. The public canteens of various colleges, enterprises and institutions have basically realized standardization and networking, but the work of selling meals in the canteens still adopts traditional management. The method of manual cooking by personnel greatly limits work efficiency and has many disadvantages. For example: (1) can not be accurately quantified: the amount of food for manual cooking is mainly based on experience, and it is impossible to weigh again and again. (2) A lot of human and financial resources are wasted: During the peak period of cooking, an employee has to cook hundreds or even thousands of bowls of rice in about an hour, which is a heavy workload. (3) Low efficiency of cooking: some employees are inexperienced, or the speed of cooking is not fast, which can easily cause dissatisfaction among consumers, long queues, and overcrowded cafeterias. Need to research and develop self-service cooking equipment for this reason.

At present, although there are some theoretical researches in China, they have not yet developed this kind of machine, most of which are only limited to the theoretical part, and there are still many disadvantages: ① Rice has a high viscosity and is easy to adhere to the inner wall of the lunch box It cannot slide down, and the requirements for the rice delivery mechanism are also very high. The traditional screw rod or rotating blade can not meet the requirements well; ②Because the rice is not uniform, so the ration of rice is also required. , The traditional weight-recording method increases the cost of equipment and is less efficient.

According to the current development concept, a high degree of automation of mechanical equipment will replace traditional human labor. Now the government is also advocating "machine substitution", so the research and development of automated mechanical equipment will also become a popular direction of scientific research. Therefore, under the condition of not changing the existing canteen card swiping system, it is of great significance to research and develop a set of fully automatic rice cooking system that can realize real "intelligence".

Contents of the invention

In order to overcome the problems of inaccuracy and low efficiency in the traditional manual cooking method, as well as the complex structure of the existing rice cooking machine, the inability to realize the self-service cooking function, and low work efficiency, the utility model provides a fully "intelligent" It is a self-service rice cooker with high work efficiency and can fulfill the requirements of cooking rice well.

The technical scheme that the utility model adopts is:

The self-service rice making machine includes a frame, and it is characterized in that: a rice conveying mechanism, a drum driving mechanism, a rice pushing mechanism and a control system are sequentially arranged in the frame from top to bottom, and the control system controls the The rice push mechanism;

The rice dredging mechanism includes a rice storage box, a drum and a feeding pipe, the rice storage box is arranged on the frame, the inlet end of the drum is connected with the outlet end of the rice storage box, the The outlet end of the drum is connected with the inlet end of the feeding pipe;

The drum drive mechanism includes an AC motor for driving the drum, a belt, a gear and a spur gear. The two ends of the belt are respectively sleeved on the rotating shaft and the gear of the AC motor. The spur gears are meshed, and the spur gears are arranged on the rollers;

The rice pushing mechanism includes a push rod, a cylinder for driving the push rod and an air pump to provide power, the push rod is arranged below the outlet end of the feeding pipe, the cylinder and the control system connection.

Further, the rice storage box and the feeding pipe are vertically arranged on the frame, and the rollers are arranged horizontally on the frame.

Further, the control system includes a controller and an operation panel for controlling the movement of the cylinder, and the controller is connected to the operation panel for signals; the operation panel is provided with a card slot, a display and operation buttons, and the The card swiping slot, the display and the operation buttons are connected with the controller.

Further, several spiral pieces are welded on the inner wall of the drum, and the gaps between the spiral pieces form spiral grooves.

Further, the drum is conical and placed horizontally, the inlet end is a large conical port, and the outlet end is a small conical port.

Further, the inner wall of the drum and the feeding tube and the outer surface of the push rod are coated with an anti-sticking coating.

Further, the frame is also provided with supporting rollers for supporting the rolling of the drum.

In the utility model, the AC motor is the power source for the roller to turn up and down. The gears and belts that transmit the power have two stages of transmission. The first stage is a belt drive. The AC motor is connected with the gear through the belt. Because the belt will slip when the working load exceeds the standard , can play the role of overload protection and prevent the AC motor from being burned due to excessive current. This is also the reason why many motors use a belt for the first-stage transmission, and the second-stage transmission is gear transmission, which is welded on the outer ring of the drum. There is a pair of spur gears. The spur gears are located in the middle of the drum to prevent additional loads due to the unbalanced force during the rotation process. The spur gears are easier to process than the helical gears and can meet the work requirements, so although the drum is conical , the gear still chooses the spur gear.

In the utility model, since the rice has been dispersed evenly, the amount of rice can be calculated according to the stroke of the push rod, which replaces the traditional weight-recording method, and has higher efficiency and lower cost.

In the utility model, the controller can be selected from PLC, which can well meet the requirements, and the programming is simple, the operation is convenient, and the cost is low; the operation panel (card reader), the customer can choose the amount of rice according to his own needs, After pressing the operation button, the card is swiped in the card slot. After the card is swiped, the display shows the deduction amount, and the CPU transmits the information to the controller, which drives the cylinder, which acts to push out the rice.

When the utility model is used, the customer first selects the amount of rice he wants to eat on the operation panel, presses the operation button, and then puts the meal card in the card slot, the card reader automatically deducts the amount used, and displays it on the display, and then sends the signal The signal is transmitted to the PLC controller, and the signal is processed by the PLC and transmitted to the cylinder. The cylinder moves forward and drives the push rod to push the rice out. The operation is convenient and simple.

The beneficial effects of the utility model are:

1. The equipment is fully automatic. Customers only need to select the amount of rice they need on the control panel and swipe the card. The operation is convenient and simple. After the card is swiped, the push rod immediately pushes out the rice, which is efficient and fast;

2. Solved the problem of rice sticking. A large part of the reason why the self-service rice maker has not been well promoted and applied is due to the stickiness of rice, which cannot be sold automatically like drinks or paper towels. On the inner wall that the whole rice contacts, Including the rice storage box, roller, feeding pipe, and push rod, all are coated with "Teflon" (anti-stick coating) to prevent the rice from sticking, and a roller is added in the middle of the rice channeling mechanism to make the rice fully roll up and down. Maximum loose and uniform rice;

3. The rice pushing mechanism adopts a push rod, and the quantity of rice depends on the push of the push rod, which is simple and convenient, and has changed the traditional weight-recording method;

4. Under the condition of not changing the existing card swiping system in the canteen, the automatic operation of cooking is well realized, the equipment is simplified as much as possible, and the cost is saved.
