Description

Closing machine for FIBC

This creation is related to the container bag, more specifically, it is a mechanism that shrinks the long cylindrical mouth of the container bag into a bundle-shaped section, and the bundle-shaped section helps to bind the workpiece (C-shaped buckle and I-bar) for strapping.

After the container bags are assembled and packaged, the mouth of the bag is tied up with ropes by manpower, which is laborious and time-consuming, and there are often problems with the mouth not being tight, especially for container bags made of thick fabrics, where the mouth of the bag is particularly difficult to tighten. Before releasing the contents in the bag, it is also necessary to loosen the rope manually, which is also laborious and time-consuming.

In order to solve the above problems, the author of this case developed a workpiece specially used for bag binding of container bags and obtained patent rights of TWM603434, TWI745004, and TWM612595.

A mechanical workpiece (such as a mechanical arm) that moves linearly back and forth clamps the C-shaped buckle 10 and the I-shaped bar 11 and operates the two to move relative to each other. After the bag opening 13 of the container bag 12 is roughly closed, the C-shaped button 10 and the I-shaped bar 11 move toward the closing part of the bag opening 13, and the two buckle feet 101 of the C-shaped button 10 penetrate into the two sides of the I-shaped bar 11. Through the opening 111, the mechanical workpiece continues to operate the C-shaped buckle 10 and the I-shaped bar 11 to move relative to the pocket opening 13, and the C-shaped buckle 10 and the I-shaped bar 11 lock each other to keep the pocket mouth 13 tight.

When taking out the article in the container bag 12, you can use the scissors to cut off the C-shaped buckle and the I-shaped bar, and the sack 13 of the container bag 12 can be opened.

In order to make the bag mouth of the container bag can be successfully bound by the C-shaped buckle and the I-shaped bar of the prior art, this creation proposes a bag mouth closing machine for the container bag. Through this converging machine, the bag opening of the container bag is partially shrunk into a bundle section before the C-shaped buckle and the I-shaped rod are bundled, so that the C-shaped button and the I-shaped rod can close the bag mouth in the bundle section. Bundle bundled.
