Plastic packaging bag sealing air tightness detection device

Abstract

The plastic packaging bag sealing airtightness detection device comprises a shell, a top shell, a moving assembly, a lifting plate, a pressure detector, a fixed shell, a packaging bag and a fixed assembly, the top shell is arranged on the top in the shell, the moving assembly is arranged on the top shell, the lifting plate is arranged in the shell in a sliding mode, the lifting plate is arranged in the shell in a sliding mode, and the pressure detector is arranged on the pressure detector. The pressure detector is arranged on the lifting plate, the fixing shell is arranged at the bottom in the shell, the packaging bag is arranged on the top of the fixing shell, and the fixing assembly is arranged in the fixing shell. The invention belongs to the technical field of air tightness detection, and particularly relates to an air tightness detection device which can drive a pressure detector to move through a moving assembly, so that detection is flexible, pressure in a packaging bag is detected through the pressure detector when the packaging bag is extruded, the packaging bag is prevented from leaking air and entering water drops, and the packaging bag can be fixed through a fixing assembly. The sealing airtightness detection device for the plastic packaging bag can prevent the packaging bag from sliding.

Description

technical field [0001] The invention belongs to the technical field of air tightness detection, in particular to an air tightness detection device of a plastic packaging bag seal. Background technique [0002] Plastic packaging bag is a kind of packaging bag that uses plastic as raw material and is used in the production of various supplies in life. It is widely used in daily life and industrial production. Plastic packaging bags are divided into two categories according to their uses, which can be divided into plastic packaging bags for daily use and industrial plastic packaging bags. When making plastic packaging bags, full attention should be paid to the sealing rate of the product to ensure product quality. [0003] The existing detection device is relatively complex in structure and cannot perform flexible detection, and water droplets are formed in the packaging bag after the packaging bag leaks, and it is inconvenient to fix the packaging bag, and it is easy to cause ...
