Dual anti-overflow goes out system of beating cream

Technical Field

The utility model relates to the field of oral product processing equipment, in particular to a dual anti-overflow paste-beating system.

Background

The fluoride-containing toothpaste is toothpaste containing fluoride, researches show that the fluoride can form a fluoride-containing mineralization system with mineral salts such as calcium, phosphorus and the like in a tooth body, on one hand, fluorine ions can replace hydroxyl in the mineral salts of tooth tissues to form fluoride-containing mineral salts, and the dental caries resistance of teeth is enhanced; on the other hand, fluoride can promote the deposition of mineral substances on the surface of teeth, remineralize early decayed teeth and repair enamel. In the production process of the fluorine-containing toothpaste, paste filling is an essential link, and the premixed paste needs to be quantitatively filled into containers such as toothpaste hoses. After being homogenized and stirred, the toothpaste can be temporarily stored in the storage tank uniformly, then the toothpaste is pumped into a funnel of a filling machine from the storage tank under the control of a toothpaste pumping system, and then the toothpaste is quantitatively filled by the filling machine.

At present, a paste pumping pump in a paste pumping system of my department is controlled by the liquid level of a funnel, the liquid level in the funnel is detected through an electrode, and when the liquid level of the funnel is lower, the controller is used for controlling the paste pumping pump to start to pump paste into the funnel; when the liquid level of the funnel is detected to be higher, the liquid level of the paste body is conducted with the electrodes, the circuit board transmits the signal to the controller, the paste pumping pump is controlled to be closed by the controller, the paste stops being discharged, and therefore the paste body in the funnel can be prevented from overflowing. However, in the long-term use process, after the filling machine breaks down, the paste pumping pump sometimes does not stop working, the paste can be continuously discharged, the paste in the hopper overflows, the filling trolley platform is seriously polluted, and a production team must stop production and clean the site. Therefore, it is highly desirable to upgrade and modify the existing paste system.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a double anti-overflow paste pouring system to solve the problem that paste easily overflows after a filling machine of the existing paste pouring system breaks down.

When the liquid level reaches the ultrasonic detection blind area, or after the ultrasonic sensor breaks down, the electrode detection assembly plays a protective role, when the liquid level of the paste body rises to contact with the bottom of the detection electrode, the liquid level of the paste body is conducted with the electrode, the electrode circuit board transmits the signal to the controller, the controller controls the paste pumping pump to be closed, the paste pumping into the filling funnel is stopped, and the paste body is prevented from overflowing.
