[0035] Working principle: When the liquid food to be sampled is transported to the worktable by the conveyor belt, the control system can control the servo motors of the XYZ axes to drive the lead screw to rotate according to the pre-set program. The rotating lead screw drives the slider to move linearly along the guide rail. Under the action of the three axes, the sampler can sample the sample at any position in the worktable. The collection bottle is pre-evacuated to a negative pressure state by the vacuum pump. After sampling, the sample enters the collection bottle through the hose under atmospheric pressure. The pressure sensor can detect the pressure in the bottle and transmit the signal to the control system. After receiving the signal, the control system compares it with the pre-set pressure value and controls the vacuum pump to keep the pressure in the bottle at a relatively constant state. Quantitative sampling can be achieved by controlling the energization time of the electromagnet.
