GM-3500 Auto. Folder Gluer


Equipment Introduction:

GM-3500, a new generation of Auto. Folder Gluer, is specially designed for the materials of cardboard, E, B, A, AB, BC and AC flute corrugated board. In addition to making straight-line, double-side and crash-lock bottom carton, it is available to make 4-corner and 6-corner cartons. GM-3500 is built with high precision and high efficiency technology Auto. 4/6-corner folder gluer.

Main Features:

Feeder Section

Feeder Section

The side guides and supporting shafts at the feeder section are automatically and conveniently adjustable by motor; With Air Pressing Feeding knives to achieve a smooth feeding, even when blanks are curved and transformed on the shapes.

Crash-Lock bottom Section

Crash-Lock bottom Section

Air-type of Upper Pressing Bar to coordinate with longer shape of crash-lock bottom carton. With high-steel of spring hookers to make hooking procedure at higher speed.

The hooks can be positioned automatically. When hooks are not required, they can be simply lifted up by air cylinder and it is no need to disassemble them to fasten the set-up speed.

Two-Piece Jointer (Option)

Two-Piece Jointer (Option)

Unlike other manufacturers’ products, our priority is to pursuit the highest accuracy and lowest consumption by adopting the leading technology of fully automatic Two-Piece Jointer.

Final-Folder Section

Final-Folder Section

Multi-angle guide wheels and large-size folding belts are equipped with high-power motors to produce 3-layer and 5-layer corrugated boxes more stably.

It enforces the folding strength to form cartons precisely and offers a great help to avoid the possibility that the groove lines between flutes become the folding lines and to reduce the problem of fish tails.

Servo Regulator Section

Servo Regulator Section

By using the chains to guide and push the blanks to move correctly without slanting problem for the next procedures.

Trombone Section

Trombone Section

Upper & lower belt carriers are by independently multiple-phase electrical control. According to the blank designs for auto. setting. Available to add Alignment Device to avoid fish-tail problem.

Auto. Glue Injection System

Auto. Glue Injection System

Both Cold Glue and Hot Melt Injection System can be applied to joint medium and large size of cartons.  The jointed effect can be as strong as stitching cartons to reduce the use of metal nails. This is very helpful for recycling purpose.

Pressing Conveyor Section

Pressing Conveyor Section

Heavy duty Pressing Conveyor Section for fast operation to ensure bonding strength without re-opening issue. The electronic sensor can automatically adjust the conveyor speed working with the main machine.

Efficiency Improvement:

We take care of much more details on design and manufacturing of equipment for high efficiency and reduce losses. Improve production to save time and labor.
