Main Application

All-round detection of leaks in the Lianpai plastic ampoules produced by the blow-fill-sealing three-in-one production, as well as Lianpai eye drops, Lianpai oral liquid and other similar packaging products.

Working principle

Put the row plastic ampoules into the interval of the conveying device manually (the automatic bottle loading part can be customized), and the conveying device will transport the row plastic ampoules to the detection channel, and then pass through the detection channels 1 and 2 in turn; respectively detect the row plastics The bottle body, head and tail of the ampoule; then through the turning wheel mechanism, they are transported to the inspection channels 3 and 4 in turn; the head, tail and bottle body on the other side of the row of plastic ampoules are detected; finally the qualified products and the body are separated by the waste rejection mechanism Unqualified products: Qualified products are transported to the subsequent stations through the genuine conveyor belt, and the unqualified products enter the waste collection basket through the reject mechanism (the collection basket is provided by the user, not listed in Figure 1).

Detection principle

The detection principle is shown in Figure 2-1. In the figure, V is a high-frequency and high-voltage power supply, and its two ends are connected to the emitter and the receiver respectively; C1 and C2 are the capacitance between the emitter, the receiver and the solution (because the solution and the There is a container wall between the electrodes, and there is no direct contact, so capacitance is generated); R is the resistance of the solution (the conductivity of the solution is ≥1.2µS, otherwise the detection effect may be poor or impossible).

When the row of plastic ampoules does not leak, the simplified circuit of the entire loop is shown in Figure 2-2. At this time, the circuit will generate a micro current I1;

When the plastic ampule leaks, the electrode and the solution will be directly connected, and the capacitance generated by the container wall disappears. The simplified circuit of the entire circuit is shown in Figure 2-3; at this time, the circuit will generate a current I2;

By comparing the size of I1 and I2, it can be judged whether there is leakage in the plastic ampoules.
