This method is a more effective solution to solve the problem that the cover of the unpacking machine is not smooth before folding, and even the size of the carton can be used. But the cost of this method will be a relatively high price, if not necessary, users generally will not choose to install;
Second, the installation of auxiliary cover mechanism:

This method is different in the form of each manufacturer, some are equipped with a cylinder oblique push, some are equipped with two cylinders direct push, but no matter which can achieve the function of the auxiliary cover, and is a more economical solution, the use of more;

Third, cut corners to the carton:
Theoretically speaking, any size carton should be cut corners as long as it is used on the unpacking machine, but because of the high cost of cutting corners, users generally only cut corners when the manufacturer has requirements, most of the time, it is not cut corners, but for large cartons, the packaging recommendations we give are still to cut corners, although cutting corners is a way to solve the difficulty of folding cover. However, we hope that the user can install an auxiliary cover mechanism at the same time of cutting corners, so that the use of the unpacking machine will be smoother.
The above is the unpacking machine before folding cover is not smooth treatment method. In fact, the main reason why the cover is not smooth before the unpacking machine is folded is that after the carton is large, the top cover will be relatively long, the strength required when folding the cover will be greater, and the carton will be blocked or dropped using the same strength, so we can effectively solve these problems through the above processing methods, so as to ensure the normal operation of the unpacking machine.
