The first step is the suction link, which is the first step of the unpacking machine. When the operator puts the flat carton into the hopper, the unpacking machine will use its own sucker to suck the carton in the hopper. At the same time of suction, it will have a force to pull back, which is used to suck the flat carton into the shape of a carton.
The second step is the bottom folding step. After the unpacking machine completes the first suction step, the carton is basically formed. At this time, it is necessary to fold the bottom, which is similar to the folding principle of the folding and sealing machine. The equipment folds the two short sides of the bottom of the carton, and then folds the longer sides, and then the whole folding work is completed.
Third, the back sealing link. Compared with the above two links, the back sealing work is very simple, basically the same as the standard box sealing machine. It is driven by the box sealing belt, which drives the carton to move forward. In the process of moving, the bottom of the carton is sealed with the box sealing tape, and then transported to the next working area.
