Embodiment Construction
[0017] The packaging bag leakage detection mechanism includes the detection mechanism body and at least one detection cavity 1 arranged inside the body, at least one stopper part and the conveyor belt 3 arranged at the lower part of the detection cavity 1, the detection cavity 1 and the stopper The material part moves synchronously with the conveyor belt 3, the upper part of the detection chamber 1 is connected with a vacuum pump, and the stopper part is arranged on the side of the cavity 1, and the stopper part is a combination of the ratchet 4, the cam 5 and the stopper rod 7. Each cam 5 wears on the same shaft 6, and the ratchet 4 drives the cam 5 to rotate through the shaft 6. The ratchet 4 is controlled by the cylinder, and each action of the cylinder is sequential, and the ratchet 4 rotates 90 degrees.
[0018] The lower end of the detection cavity 1 of the present invention is pressed against the conveyor belt 3, the sealing element is sealed with the conveyor belt 3 by ...

The invention discloses a packaging bag leakage detection mechanism. The packaging bag leakage detection mechanism comprises a detection mechanism body and at least one detection cavity arranged inside the detection mechanism body, and at least one material blocking part and a conveyer belt arranged at the lower portion of the detection cavity, wherein the detection cavity and the material blocking part moves synchronously with the conveyer belt, the upper portion of the detection cavity is connected with a vacuum pump, the material blocking part is arranged at the side portion of the cavity, each material blocking part works in such a way that a ratchet, a cam and a material blocking rod are linked in a combined manner, each cam is arranged on the same shaft in a penetrated manner, each ratchet is controlled by a cylinder, and every time when the cylinder acts once, the corresponding ratchet rotates 90 degrees. According to the invention, the leakage condition of a packaging bag can be rapidly and accurately detected, and unqualified packaging bags are rejected timely; and the packaging bag leakage detection mechanism has the advantages of small equipment occupation space, high detection precision and high detection efficiency.
Description
1. Technical field [0001] The invention relates to a packaging bag leakage detection mechanism. 2. Background technology [0002] At present, flexible packaging is often used in the packaging of liquid, gaseous, and solid items, involving several major fields such as food, medicine, biochemistry, washing, etc. The sealing strength is the protection strength of the flexible packaging for the contents, which is an important property of the flexible packaging. It directly affects the shelf life of the contents, so it is very important to test the seal strength of the package. [0003] At present, there is no special packaging bag leakage detection equipment, all of which are through manual observation and manual recording. The detection accuracy is low, the efficiency is poor, and it is inconvenient to feed back the detection data in a timely manner. 3. Contents of the invention [0004] In order to overcome the above drawbacks, the present invention provides a packaging bag...
