When it comes to the packaging industry, it is crucial to ensure that the bottom of the box is strong and secure. The bottom-lock folder-gluer is a key technology, how does it realize the strong bottom sealing of the packaging box?

The working principle of the bottom lock folder gluer:

A bottom lock folder gluer is a highly automated piece of equipment designed to create a strong seal on the bottom of a box. Its working principle includes the following key steps:

1. Cardboard supply

Initially, cardboard or carton panels are fed into the infeed system of the bottom lock folder-gluer. These sheets usually come from rolls or pre-cut sheets.

2. Cardboard forming

Next, the folder-gluer flattens the cardboard material and feeds it into the forming area. Here, the cardboard is folded, bent and compressed according to the desired box shape and dimensions to form the bottom and side walls of the box.

3. Bonding

Once the shape of the box is complete, the folder gluer automatically applies the adhesive or glue to the bottom of the box. This ensures a strong bond on the bottom so it won't come loose during shipping or storage.

4. Pressing and locking

After the gluing is complete, the boxes are sent into the pressing area. Here, the machine compacts the adhesive thoroughly by applying pressure, ensuring a secure bottom seal. At the same time, some bottom-lock folder-gluers also have a locking mechanism to further strengthen the stability of the bottom.

5. Testing and Quality Control

Folder-gluers are often equipped with sensors and vision systems to detect any possible defects or inconsistencies. If a problem is found, the machine can take immediate corrective action to ensure that the bottom of each box is solid.
