The positioning platform 220 is provided with a visual positioning device and a limiting structure matching the shape of the cardboard, so that the cardboard is accurately limited to facilitate subsequent operations; after completing the positioning, the synchronous material moving assembly 210 transfers the cardboard to the first pre-folding mechanism 230 and the second pre-folding mechanism 240 and even the first turntable 310 in sequence, performs the first and second pre-folding on the cardboard, and then transfers it to the glue dispensing device 300 to prepare for glue dispensing.

[0057] Preferably, the first horizontal driving mechanism 211 and the first lifting mechanism 213 both adopt a hydraulic cylinder or a pneumatic cylinder.

[0058] Specifically, Figure 6 As shown, the first pre-folding mechanism 230 includes a pre-folding platform 231, rollers 232 arranged on both sides of the pre-folding platform 231, a linear cylinder 233 arranged below the pre-folding platform 231, a roller bracket 234 and a curved track 235; wherein, the roller 232 is installed on the roller bracket 234, two small pulleys are arranged on both sides of the roller bracket 234, and the roller bracket 234 is installed in the curved track 235 through the small pulleys on both sides, wherein one end of the curved track 235 is a horizontal track and the other end forms a certain slope; the roller bracket 234 is hinged to the movable end of the linear cylinder 233.

In addition, the glue dispensing mechanism 320 is a prior art and will not be described here. The structure of turntable transmission allows the loading, glue dispensing and unloading stations to operate simultaneously, which greatly improves the machine operation efficiency.

Finally, during the lifting process of the ejector discharging mechanism 523, the ejector is ejected, so that the cigarette box is separated from the pressing plate. The molding module 520 of this embodiment uses only one power source to drive the linkage of multiple folding steps, which greatly improves the level of automated operation.
