Automatic electronic microporous leakage detecting machine for flexible bag

Abstract

The invention discloses an automatic electronic microporous leakage detecting machine for a flexible bag. The automatic electronic microporous leakage detecting machine comprises a stander (2), bag feeding tracks (1) which runs independently, reject picking mechanisms (10) and bag discharging tracks (4), wherein the front part and the rear part of the stander (2) are respectively provided with the bag feeding tracks (1) and the reject picking mechanisms (10), a detecting passage (3) is arranged above the stander (2), the detecting passage (3) is at least provided with two groups of high-frequency high-voltage leakage detecting devices, each high-frequency high-voltage leakage detecting device consists of a high-frequency high-voltage leakage detecting power supply control device (9), a receiving electrode (7) and a transmitting electrode (6), the receiving electrodes (7) are connected with receiving ends of the high-frequency high-voltage leakage detecting power supply control devices (9), the transmitting electrodes (6) are connected with transmitting ends of the high-frequency high-voltage leakage detecting power supply control devices (9), and each high-frequency high-voltage leakage detecting device is connected with the reject picking mechanisms (10) through a control system. The automatic electronic microporous leakage detecting machine for the flexible bag has the advantages of high detection accuracy, high detection efficiency, high detection safety and no secondary pollution.

Description

technical field [0001] The invention relates to a leak detection machine, in particular to an automatic electronic microporous leak detection machine for soft bags, which is mainly used for leak detection of large infusion soft bags in the pharmaceutical industry, including micropores (greater than 0.5 μm), bag body Detection of defects at press joints, pocket welds, bag nozzle welds, etc. Background technique [0002] At present, the leak detection of infusion soft bags in the pharmaceutical industry mainly adopts the following methods: [0003] 1. Leak detection in the high-pressure sterilizer. While the infusion soft bag is being sterilized in the sterilizer, a certain pressure is applied. After sterilization, manually check whether the capacity has changed. When the infusion soft bag has micropores and tiny cracks, and the volume change is small, which is not enough for manual and accurate judgment, it is very easy to cause secondary pollution of the drug solution in th...

Problems solved by technology

When the infusion soft bag has micropores and tiny cracks, and the volume change is small, which is not enough for manual and accurate judgment, it is very easy to cause secondary pollution of the drug solution in the soft bag;

[0004] 2. Vacuum leak detection (dye liquid leak detection), which is divided into positive pressure and negative pressure leak detection. This method is to use the dyeing solution to apply positive or negative pressure to the soft bag, and observe whether the color of the liquid changes. When it is difficult to judge the change manually, and when the liquid itself is colored, it is very easy to cause misjudgment, and it is also very easy to cause secondary pollution of the liquid in the soft bag;

Due to individual differences, the misjudgment rate is extremely high, and it is only suitable for the detection of single-chamber soft bags. When the soft bag is a multi-chamber bag, it is easy to cause rupture of the inner cavity diaphragm of the bag

It is also very easy to cause the liquid medicine in the soft bag to be polluted twice by the outside, causing a great risk
