Packaging leakproofness detecting device for liquid packaging bag

Abstract

The invention discloses a packaging leakproofness detecting device for a liquid packaging bag. The packaging leakproofness detecting device comprises a supporting plate, a pressuring plate, a downward-pressing driving mechanism, a cantilever, a color sensor, a pressure sensor and a controller; the color sensor is arranged at the bottom of the cantilever and is positioned above the supporting plate; the downward-pressing driving mechanism is positioned in front of the cantilever; the pressing p late is arranged at the bottom of the downward-pressing driving mechanism and is positioned above thesupporting plate; the pressure sensor is arranged on the supporting plate and is positioned below the pressing plate; the color sensor is connected with the controller in order to realize position signal transmission for the liquid packaging bag; the pressure sensor is connected with the controller in order to realize pressure signal transmission for the liquid packaging bag; and the controller is connected with the downward-pressing driving mechanism in order to realize stretch and contraction control. Through the way, the packaging leakproofness detecting device for the liquid packaging bagdisclosed by the invention is high in production efficiency and can find out liquid packaging bags which are not sealed completely in time so as to prevent deliver of defective products.

Description

technical field [0001] The invention relates to the technical field of detection of liquid packaging bags, in particular to a device for detecting sealing performance of liquid packaging bags. Background technique [0002] Liquid packaging bags are widely used, such as instant noodle seasoning packets, sauce packets, plastic bagged beverages, bagged food, and bagged washing liquid, all of which require liquid packaging bags. In order to ensure product quality and longevity, liquid packaging bags need to be sealed. [0003] Due to defects in sealing equipment and improper operation, the tightness of liquid packaging bags cannot be fully guaranteed. In particular, poor sealing of liquid packaging bags will affect food quality and lead to centralized recalls of the same batch of products, which still need to be tested. In the prior art, the seal detection of packaging bags is mostly carried out by inflating air in a closed detection cover, such as a seal detection device discl...

Problems solved by technology

[0003] Due to the defects of sealing equipment and improper operation, the tightness of the liquid packaging bags cannot be fully guaranteed. In particular, the poor sealing of liquid packaging bags will affect the quality of food and lead to the problem of centralized recall of the same batch of products, which still needs to be tested

In the prior art, the sealing detection of the packaging bag is mostly carried out by inflating the air in a closed detection cover, such as a sealing detection device disclosed in CN201120019619.9, which takes a long time to detect and has low work efficiency, which is not suitable for continuous production of batch products. Production and testing, needs improvement
