Technical Field

[0002] Food additives are natural or synthetic chemical substances added to improve the sensory properties and quality of food. They are very commonly used in food processing. Currently, food additives are usually added manually during food processing. However, there are many types of food additives, and manual addition not only makes it difficult to accurately control the amount added, but also easily leads to confusion and errors.

A central fixed shaft is fixed at the center of the base plate, and a support frame is fixed on the base plate. The support frame fixes the top mounting ring. Four additive containers are evenly distributed on the top mounting ring. A rotating plate is rotatably mounted on the central fixed shaft. The rotating plate is driven to rotate, and the rotation of the rotating plate can transfer the food container to be added to different positions to add different food additives. Four additive containers are evenly distributed on the rotating plate. A placement frame with a clamping placement part is provided within the placement frame. The food box is stably placed through the clamping placement part. A rotating plate is fixed to the middle section of the central fixed shaft. Four transparent measuring containers with graduation lines are fixed on the rotating plate. A piston rod extends into the transparent measuring containers with graduation lines, and a rubber piston is fixed to the end of the rod. A top limiting plate is fixed to the top of the piston rod. A support spring connects the top limiting plate and the upper surface of the transparent measuring containers with graduation lines. Without applying external force, the support spring can push up the top limiting plate, so that the internal piston is located at the top of the transparent measuring container with graduation lines. The top limiting plate is limited by a limiting and metering structure set on the central fixed shaft. According to the needs, the rubber piston is positioned at the corresponding height through the cooperation of the limiting and metering structure and the support spring, so as to quantify the food additives that can enter the transparent measuring containers with graduation lines.

[0004] As a preferred technical solution of this utility model, the rotation drive includes a stepper motor and a gear. Gear grooves are distributed on the outer side wall of the rotating plate. The stepper motor is fixedly installed on the right front corner of the base plate. The gear is installed on the output shaft of the stepper motor and meshes with the gear grooves on the side wall of the rotating plate.

[0005] As a preferred technical solution of this utility model, the clamping and placing part includes a mounting groove, a spring, a movable sleeve block, and a trapezoidal clamping plate. The mounting groove is opened on the bottom surface of the placing frame, and a shaft is fixed in the mounting groove. The movable sleeve block is placed in the mounting groove and is movably sleeved with the shaft. The spring is fixed to the inner side wall of the mounting groove. The whole is sleeved off the shaft, and the other end is fixedly connected to the side wall of the movable sleeve block. The trapezoidal clamping plate is fixedly installed on the movable sleeve block. The inclined part of the trapezoidal clamping plate facilitates pressing the food box downwards into the placing frame, while the inner vertical part of the trapezoidal clamping plate can ultimately and stably clamp the food box.

[0006] As a preferred technical solution of this utility model, the limiting and metering structure includes an electric actuator, an electric actuator output shaft, a threaded hole, and a mounting shaft.

The side wall of the electric actuator output shaft has a threaded hole, and the mounting shaft is installed in the threaded hole with threaded fit. The mounting shaft is placed on the upper part of the top limiting plate to limit it.

[0007] As a preferred technical solution of this utility model, the electric actuator, solenoid valve, and stepper motor are powered by an external power supply and controlled by a PLC controller. The mounting shaft is made of rigid material. All of the above are conventional technologies. The control of the PLC controller is determined through a limited number of experiments based on the actual addition process. When the stepper motor stops, the electric actuator is started, the first solenoid valve is closed and the solenoid valve is opened to add food additives. When the stepper motor rotates, the electric actuator is reset, the first solenoid valve is opened and the solenoid valve is closed.

[0008] The beneficial effects of this utility model are as follows: the food box is stably placed in the placement frame by the clamping and placement part, and the rotation drive drives the rotating plate to rotate so that the food box to be added food additives is transferred to different positions to add different food additives. By inserting the fitting shaft into different threaded holes, the top limiting plate is at different heights, so that the rubber piston at the lower end of the piston rod is in different positions in the transparent quantitative container with scale lines to achieve quantitative addition of additives in the transparent quantitative container with scale lines. When the electric push rod is started and the output shaft of the electric push rod moves down, it drives the fitting shaft to press down the top limiting plate and open the solenoid valve to output the additives.

The top limiting plate 17 is limited by the limiting quantitative structure provided on the central fixed shaft 101.

[0015] As a preferred technical solution of this utility model, the rotation drive can drive the rotating plate to rotate, change the position of the food box, and add different additives.

[0016] As a preferred technical solution of this utility model, the clamping and placement part includes a mounting groove 10, a spring 11, a movable sleeve block 12 and a trapezoidal clamping plate 13.

When the stepper motor stops, it starts the electric push rod, closes the first solenoid valve, and opens the solenoid valve to add food additives. When the stepper motor rotates, the electric push rod resets, opens the first solenoid valve, and closes the solenoid valve. When the first solenoid valve is opened and the solenoid valve is closed, the additive enters the graduated transparent metering container. The metering method is to install different configuration shafts in different threaded holes so that the top limit plate is at a predetermined height, which ensures that the rubber piston is at the corresponding height inside the graduated transparent metering container. This fixes the maximum storage capacity of the graduated transparent metering container, making the addition more accurate, and the multi-position addition reduces the possibility of various additives getting mixed up.
