PU sandwich panel of Quanlong is continuously and automatically working. The requirement of the workshop is LXWXH about 120mx4mx8m

De-coiler frame level fix—loading car outside moving—steel coiler lifting—loading car inside moving to the out edge of frame—loading car lift making the center of steel coiler same as de-coiler frame center—loading car inside moving to the inner edge of the frame—the frame intension—arm press—loading car back position—de-coiler main shaft rotation, the coiler start de-coiling. lamination and cutting system. Lamination is to avoid the painting damage, cutter is to cut the panel in different condition of specification.

steel slitting

Cylinder lower down—driving roller press the steel sheet—feeding sheet—cutter motor starts—cutter—-cutter back position—cylinder back position

up lamination

Film installing— cylinder lower down— laminating shaft press the steel sheet—tension adjusting—driving roller starts—laminating—sheet enter the forming machine—roller driving stop—roller relax—passive laminating

Forming machine is consisted with up forming machine, down forming machine, forming machine table, connection roller. Profile shape based on customer’s requirement

pre-heating room

Pre-heater is air heating, heating source is supplied by customer, could be steam, gas, Fuel oiler…etc.

servo motor for gun frame

Gun frame is made to install the injection gun, frame use servo motor to make precision movement.

Back glue, white glue, foam additives, catalyst, fire retardant –– pray gun ready– black and white glue cycling-white glue and fire retardant pre-mixing , glue temperature adjust- spray glue with proper proportion. 2/4/6 components continuously high-pressure foaming machine technical specification

Gun frame is used to install gun with servo motor to assure the precision of the gun movement.

band saw cutter

Band saw cutter consists of middle roller, band saw and speed roller. working process: Panel Feeding— press— band saw starts—cylinder starts, cutter and panel moving—cutter—cylinder relax—panel stay moving—saw stops and rotation to position—cylinder back position

cooling bed

The finished sandwich panel goes to cooling bed by the roller conveyor, and goes to the stacker by the rollers from after cooling

To Send the cooled sheet that cut by saw machine to the specific spot; mechanical arm stacks the sheet automatically.

electrical control system

To control the whole line with PLC and inverter

packing

T Packing the finishes sheets with lamination that stacked by the auto-stacker, it can avoid external damage in the sheet, which is easy to stock and deliver.
