Abstract

The invention discloses a mechanism for manufacturing a leakage-proof valve port. The mechanism comprises elements such as a paper frame and the like, wherein the paper frame is mounted between a base and a top base; a PE (polyethylene) membrane frame is mounted on the lateral side of the paper frame; a tension swing roller is mounted on the lateral side of the PE membrane frame; a cutter groove roller and a cutter roller are mounted on the lateral side of the tension swing roller; a layering roller is mounted on the lateral side of the cutter roller; a first PE membrane traction roller and a second PE membrane traction roller are mounted behind the layering roller; a travel adjusting roller is arranged between the first PE membrane traction roller and the second PE membrane traction roller; a first compression roller and a second compression roller are mounted on the lateral side of the second PE membrane traction roller; a pull-apart roller is arranged on the lateral side of the second compression roller; a clamp roller is mounted on the lateral side of the pull-apart roller; a paper sticking roller is mounted on the lateral side of the clamp roller and is matched with the clamp roller; and a paper ejecting cutter is mounted on the clamp roller. According to the invention, the mechanism can directly manufacture the leakage-proof valve port with interior closing performance in an online manner; and therefore, a valve port paper bag with a leakage-proof valve port is produced automatically.

Description

technical field [0001] The invention relates to the field of packaging bag manufacturing equipment, in particular to a manufacturing mechanism for an anti-leakage valve port. Background technique [0002] At present, valve mouth paper bags are widely used in the packaging of powder materials. After filling, valve mouth paper bags have a square appearance, which is extremely convenient and safe for stacking and transportation. The valve port of the traditional valve port paper bag is rolled into a tube with paper and bonded to the valve port part. The valve port made in this way has a serious problem, that is, the valve port made of pure paper will be damaged after bonding. Very flat, after the material is filled through the valve port, the channel of the valve port is still very straight, during transportation, when bumpy, the material is easy to flow back from the valve channel, wasting materials and polluting the environment . In order to solve this problem, the soft and...
