Leak detection equipment

Abstract

The invention discloses leak detection equipment for a flexible packaging product. The leak detection equipment comprises a rack and pressurization equipment. The pressurization equipment is an air cylinder piston assembly capable of applying pressure on the flexible packaging product continuously, and the fixed end of the air cylinder piston assembly is fixedly connected with the rack. A detection platform where the flexible packaging product to be detected is placed is further fixedly arranged on the rack. The air cylinder piston assembly is connected with a pressure gage used for detecting pressure of an air cylinder. The air cylinder piston assembly adopted for pressurization can output pressure continuously with the pressure maintenance characteristic, and whether the packaging product leaks air can be detected more thoroughly through pressure detection, with a certain time length, on the packaging bag; besides, pressure changes of the air cylinder are detected through the connected pressure gage, pressure changes in the packaging product pressurized by the air cylinder are displayed accordingly, and therefore the sealing air leak condition of the flexible packaging product can be correctly reflected; manual direct leak observation is replaced with reading of the pressure gage, and therefore the leak detection equipment is more reliable and saves labor.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, more specifically, to a leak detection device used for leak detection of soft packaging products. Background technique [0002] At present, most of the existing leak detection equipment for large infusions in soft bags or PP soft bottles are simple online roller pressure detection equipment. The tightness of the packaging bag, that is, to detect whether it leaks. [0003] The specific operating principle of the online roller pressure detection equipment is: use a rubber wheel with a suitable appearance and shape to roll from the surface of the packaging bag or soft bottle under the drive of the motor. During the rolling process, the packaging is identified by the naked eye Check whether the bag or soft bottle is leaking to judge its tightness. [0004] However, the inventors have found that: the main and most fatal defect of the current simple online roller pressure detection is tha...

Problems solved by technology

[0007] In view of this, the object of the present invention is to provide a leak detection device for leak detection of flexible packaging products. The structural design of the leak detection device can effectively solve the technical problems that the leak detection operation of flexible packaging products is too dependent on manpower and the detection effect is not guaranteed.
