Structural arrangement and use effect of zipper bag making machine
- Nov 15, 2018 -

In the past, the plastic bags were sealed with a heat sealing device, and the heat-sealing device was used to attach the concave-convex chain to the plastic bag body. The heat sealing device was used for bonding and sealing the machine, and the sealing and the machine were sealed. The bonded bag is not strong enough, and its sealing edge is often unsealed. Since the material was changed to non-woven fabrics, the original plastic zipper bag machine was no longer suitable, thus introducing a new zipper bag making machine.

 

The zipper bag making machine is a non-woven zipper bag making machine capable of bonding a bag body of a non-woven zipper bag and a chain. The utility model comprises a body and a cutting device. The front end of the machine body is provided with a concave and convex chain ultrasonic welding device, and a bottom sealing ultrasonic welding device with a zipper bag and an ultrasonic welding device for pressing the two ends of the zipper are arranged in the middle of the body, and a zipper is arranged at the rear end. An ultrasonic welding device for edge sealing on both sides of the bag.

 

In the structure of the zipper bag manufacturing machine, the concave and convex chain ultrasonic welding device can weld the concave and convex chain to the non-woven bag mouth, and the bottom sealing ultrasonic welding device can seal the bottom edge of the non-woven bag body, and the zipper is attached. The ultrasonic welding device with hot pressing at both ends can weld the two ends of the concave-convex chain welded on the bag mouth, and the two ends of the concave-convex chain are bonded together to prevent the zipper head from slipping out, which brings the non-woven zipper bag. Positive use effect.
