The Benefold Eagle 2800 dual-sheet intelligent high-speed folding gluing machine features a two-in-one gluing system that automatically coordinates the ejection of both sheets. It employs suction servo positioning for paper feeding and alignment, utilizing a hot melt adhesive system to apply instant-adhesive material that precisely bonds Sheet A and Sheet B during operation. The machine supports seamless switching between single and double sheet configurations, ensuring perfect formation of both sheets (compatible with three-roll-one products).
In the first stage, a piece and B piece are pasted into one piece;
In the second section, the sheet base that fits the whole sheet is folded and formed;
In the third section, the folded color box will be corrected and compacted
The first paragraph combines A and B pieces into one piece
The second paragraph will fold and hook the entire sheet base to form it
The third paragraph will correct and compact the folded color box

Paper Department
A. B-sheet paper feeding adopts servo positioning for paper feeding;
The use of electric eyes and encoders for speed monitoring can ensure that the speeds of A and B chips are completely consistent.
Pressure Joint
Adopting a hot melt adhesive spraying system, combined with a pneumatic push plate, to quickly connect and position the A and B pieces;
The A-sheet cardboard and B-sheet cardboard have been merged into one, and the middle belt presses the hot melt adhesive application area to ensure a smooth transition of the two cardboard sheets to the next step.
Compression Section
A piece of cardboard and B piece of cardboard are combined into one at this point;
The middle belt is pressed against the hot melt adhesive application area;
Ensure that the two pieces of cardboard smoothly transition into this fold.
Bottom Sticker Section
Adopting three sets of upper and lower belts, combined with various hook bottom devices and hook aids, to meet the needs of various self fastening bottom color boxes;
Suitable for bottom and side stickers (requires optional spray glue system for gluing).
This Section
Install one set of lower paste tubes (paste tray width 10mm) on each side in this folding section;
When the paper box is formed, the left and right folding bands can be adjusted separately to ensure a perfect paper box.
Pressing Down on The Part
Two sets of expandable upper and lower straps that can adapt to various lengths of box shapes;
Using a photoelectric counter to preset quantitative counting and control the kick plate to automatically mark the paper box.
Capture All Devices Together
Adopting independent motor control, synchronously accelerating with the machine (30% faster than the speed of this folding part), correcting the up and down lines of the paper box. Strong leveling correction can completely eliminate the high and low lines of the paper box, ensuring that the paper box has no horn mouth.
Transportation Department
The main function is to compact the adhesive part on the paper box, ensuring that the paper box is completely glued and formed;
The upper and lower conveyor belts are made of imported PVC belts with excellent wear resistance;
Using pneumatic method, adjust the pressure between the upper and lower conveyor belts to suit various thickness paper boxes.
