Device for determining water tightness

Abstract

The invention discloses a device for determining water tightness, which is characterized by comprising a location plate, a detection station backing plate, a stand column, a cylinder, a worktable, a sealing gasket hole, two startup control buttons, a scram button, a baffle, a water circulation conduit and a power supply system. The device has the advantages that as for the device, only 5 minutes are spent in generating primary experimental phenomenon, thus improving the frequency for detecting the tightness at the incision of an outer cover pull ring in the production process of the polypropylene combined cover for a plastic transfusion container, having wide quality monitor coverage area and ensuring finished product quality preferably; the device is controlled by a power supply and is driven by compressed air, and water is used for forming a sealing system which can be recycled, thus saving energy, and having no pollution and low detection cost; the device can be started as long as the two startup control buttons are pressed down at the same time; and the scram button is arranged in the device to ensure the safety of an operator.

Description

technical field [0001] The invention relates to the detection of the tightness of a combined cover. Background technique [0002] In the polypropylene combination cap for plastic infusion containers (YBB00242004), there is a test for checking the sealability of the cut marks on the pull ring of the outer cover: the purpose is to investigate whether the seal performance of the cut marks on the pull ring of the outer cover is sufficient to ensure that the medicine security. The detection method is as follows: take 10 pieces of this product, sterilize them with damp heat at 121°C for 30 minutes, let them cool to room temperature, and fill them with penetrant (65% ethanol: 10g / L methylene blue solution: 100:5) to 2 / 3 height, put it on the filter paper for 60 minutes, and the cut mark must not leak. However, it takes at least 1.5 hours to complete an experiment according to the above method. Contents of the invention [0003] The invention provides a water tightness measurin...

AI Technical Summary

Problems solved by technology

It is to solve the slow speed of testing the sealing performance of the outer cover with penetrant in the production process of the polypropylene composite cover for plastic infusion containers, the detection result is late, the efficiency is low, and it cannot meet the quality monitoring of the sealing quality of the outer cover ring cut in the production process And other issues
