[0002] Nowadays, the automated facial mask packaging equipment usually includes a carton storage mechanism (cardboard bin), a box suction mechanism, a box opening mechanism, a packaging mechanism, etc. The cartons stored in the cardboard bin are flat and unopened. The box suction mechanism sucks the bottom carton in the cardboard bin, removes it from the cardboard bin, and then transports the carton to the subsequent packaging station.

[0003] Some facial masks will adopt a combination of inner tray (inner lining) and outer packaging box. When packaging loose facial masks of this type, the process sequence is to first load a stack of loose facial masks into the inner tray (inner lining), then transport the inner tray containing the facial masks to the subsequent packaging station, and then stuff the inner tray containing the facial masks into the outer packaging box, and finally complete the sealing process of the outer packaging box.

[0086] Take the conventional inner support flattened paperboard 8 as an example, Figure 7 As shown, some of them are named for the convenience of examples and descriptions, specifically including the bottom page 81, the back page 82, the top page 83, and the front page 84. The left and right pages are not described because when the flattened cardboard 8 of the inner tray is sucked by the suction cup assembly 33 and placed on the inner tray conveyor line 4, it has been collided by the baffles on both sides of the inner tray positioning groove 41 and bent upward (the inner tray positioning groove in the accompanying drawings is only for illustration); in the figure, 10 is a stacked facial mask (or similar bag-type goods), the number of sheets is the number of packages of a box of facial masks, and 101 is an inner tray that has been filled with facial masks and folded into a box.

[0091] The tail end of the downward pressing guide rod 93 is the material moving claw 63 of the inner support transfer robot 6. When the material moving claw 63 is pressed downward by the cylinder 62, the front page 84 of the inner support can be pressed vertically downward.

[0092] The suction cup positioning assembly 94 is arranged in the middle of the inner support conveying line 4 on one side of the upper push plate assembly 91. The vacuum suction nozzle 941 can suck the inner support bottom page 81, so that when the upper plate push assembly pushes up the rear page 82 and the top page 83, the inner support can be fixed and not drift. The suction cup positioning assembly 94 includes a vacuum suction nozzle 941 and a positioning cylinder. The vacuum suction nozzle 941 is fixed on the top of the output rod of the positioning cylinder, and the vacuum suction nozzle 941 is connected to the vacuum pump through an air pipe.

[0093] The inner support folding box can be formed into a square box body through the above components and the above steps.

[0094] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
