Description

TECHNICAL FIELD

[0001] The utility model relates to food filling technology field, more specifically, the utility model relates to accurate control of food automatic filling machine. BACKGROUND

[0002] Food filling refers to the operation process that liquid or semi-liquid food is filled into a packaging container according to a predetermined amount. Through filling, food can be effectively sterilized and sealed to prevent microbial contamination and spoilage, thereby prolonging the shelf life of food. Before filling operation, the volume of the bottle is calculated, and then the control system is used for calculation and adjustment to finally determine the amount of liquid injection. If the injection bottle is misplaced or the system fails, the washing liquid will directly spill onto the machine.

[0003] Through retrieval, the China patent with the publication number CN214495694U discloses an automatic filling machine with accurate and quantitative filling. The embedded micro pressure-sensitive touch sensor can directly sense the distance of liquid injection. The pressure-sensitive touch sensor layer is directly attached to the detergent bottle opening. When the detergent reaches the position closest to the pressure-sensitive touch sensor, the pressure-sensitive touch sensor cooperates with the control system to stop liquid injection. This can effectively control the amount of liquid injection, and there is no need to further calculate the amount of detergent to be injected. This improves the accuracy of quantitative control, simplifies the filling work, and reduces the working intensity of the control system.

[0004] The above-mentioned filling machine, when used for liquid food filling, the liquid food falls into the container through the liquid injection port. When the liquid food is about to fill the container, the liquid food will be directly detected by the embedded micro pressure-sensitive touch sensor. However, when the liquid food is being filled, the surface tension or foam of the liquid food may form a misleading signal, causing the sensor to mistakenly believe that the container is close to overflowing. This makes it inconvenient to accurately control the amount, and the use effect is poor. UTILITY MODEL CONTENTS
