Four operations happen between the blank going in and the finished box coming out, and each one has a mechanism behind it that you can ask about during a factory visit.
The cover shell is fed into position. On the GR-1200ZA this is the first station of a seven-link board system, and Guorun holds granted patents on the paper feeding and conveying mechanisms behind it.
A computer-controlled nozzle sprays stripe, dot or mist patterns, and can spray fonts and logos. Because glue lands only where the pattern places it, consumption falls and there is no squeeze-out at the seam.
The shell and inner box are brought together. Semi-automatic machines hold 0.3 to 0.4 mm. The GR-580/720ZA is stated at +0.2 mm. The GR-1200ZA adds a CCD vision system and a YAMAHA four-axis robot at 2 mm placement accuracy for irregular blanks.
The assembled box is pressed to remove trapped air. Guorun's one-time automatic bubble pressing system does this without a module change between formats, which is the step that manual pressing gets wrong when a book box side comes out loose.
Fully automatic cosmetic box assembly machine with suspended shell positioning, servo linkage and one-time bubble pressing at 0-28 pcs/min and +0.2 mm forming error.
High-precision 7-link board collapsible box line with CCD vision glue dispensing and a four-axis robot, running shells to 1000 x 450 mm at 2 mm robot positioning.
Manual pressing leaves book box sides loose, which shows up later as cracking or an open seam. One-time automatic pressing removes that variable.
The four-corner holding, clamping and suction device adapts to bottomless, enclosed and bottomed inner boxes by switching mode rather than by fitting tooling.
