Double-chamber high-voltage soft bag detector

Abstract

The invention discloses a double-chamber high-voltage soft bag detector. A detection channel device is arranged on a frame; a feeding mesh belt is arranged at the feeding end of the detection channeldevice, and an output mesh belt is arranged at the discharge end; a waste removing device is arranged above the output mesh belt; the detection channel device comprises a wavy soft bag conveying beltformed by connecting a plurality of power rollers side by side through a connecting belt; a bag head detection device and a bag body detection device are arranged on a detection station of the soft bag conveying belt; the bag body detection device comprises a bag body front side detection device and a bag body back side detection device; the bag body detection device is arranged at the inclined plane position of the soft bag conveying belt, and the inclined plane is formed by connecting at least two power rollers through the connecting belt. and a bag tail clamping device is arranged above thesoft bag conveying belt. The detection stability can be improved, ridge type conveying is adopted, and the detection sensitivity is improved; detection electrodes are arranged in a crossed covering manner to reduce false detection; and the detection electrodes can be automatically adjusted according to the bag body contour, and the leakage point capture sensitivity is improved.

Description

technical field [0001] The invention belongs to the technical field of medical soft bag testing equipment, in particular to a double-chamber soft bag high-voltage testing equipment. Background technique [0002] The defect detection of the current medical infusion soft bag includes 1. Leak detection of colored water: the plastic soft bag is sterilized in the sterilizer at the same time, after being sterilized under a certain pressure, and then injected with a dye, whether there is any color change of the liquid medicine , to judge whether the soft bag leaks; 2. Vacuum leak detection: the plastic soft bag is placed in the detection chamber, and the leakage is determined by measuring the pressure change in the detection chamber; The principle of recombination crystallization, through certain physical conditions, observe whether there is crystallization on the outer surface of the plastic soft bag, so as to judge whether there is leakage of the liquid medicine; the above is the...

[0002] The defect detection of the current medical infusion soft bag includes 1. Leak detection of colored water: the plastic soft bag is sterilized in the sterilizer at the same time, after being sterilized under a certain pressure, and then injected with a dye, whether there is any color change of the liquid medicine , to judge whether the soft bag leaks; 2. Vacuum leak detection: the plastic soft bag is placed in the detection chamber, and the leakage is determined by measuring the pressure change in the detection chamber; The principle of recombination crystallization, through certain physical conditions, observe whether there is crystallization on the outer surface of the plastic soft bag, so as to judge whether there is leakage of the liquid medicine; the above is the traditional soft bag leak detection method, which has limitations to varying degrees, low efficiency, etc. ; and the current detection process is to use a flat mesh belt to transport the soft bag, and a single detection device is installed on the mesh belt to detect the head and body of the soft bag at the same time. Due to the different structures of the body and the head of the soft bag, the wall thickness Different, so a single detection device cannot accurately detect the defects of the head and the bag body, and because the liquid in the bag body cannot ensure that all positions of the bag body are filled when the soft bag is placed flat, resulting in inaccurate test results of the soft bag high pressure. Accurate, poor stability
