The embodiment also provides a production method of the flame-retardant double-sided aluminum-plastic panel, which comprises the following steps:
step S1: extruding; stirring and grinding the raw materials of the middle core layer of the aluminum-plastic plate into powder, putting the powder raw materials into an extruder 2, and performing extrusion molding through an extrusion die head to form the middle core layer;
step S2: compounding; sequentially attaching a polymer film and an aluminum film on two surfaces of the middle core layer, and uniformly performing thermal compounding treatment;
step S3: cutting; cooling and shaping the aluminum-plastic plate after thermal compounding, trimming the aluminum-plastic plate, and cutting the aluminum-plastic plate after trimming;
step S4: stacking; and stacking the cut aluminum-plastic panel, and packaging and transferring the stacked aluminum-plastic panel.
Specifically, the working principle of the invention is as follows: firstly, stirring, grinding and crushing raw materials of the middle core layer, pouring the powdery raw materials into the feeding box, the raw material in powder form is sucked into the upper hopper through the screw shaft, the extruder 2 extrudes the intermediate core layer through the extrusion die, respectively attaching a layer of polymer film on two sides of the middle core layer, passing through the space between the second compression roller and the third compression roller, passing through the space between the second compression roller and the first compression roller, and finally passing out of the three-roller calender 3 around the lower end of the first compression roller, wherein the middle core layer and the polymer film pass through the upper end of the aluminum film lower layer frame, and the upper surface and the lower surface of the polymer film are provided with aluminum films and enter the first thermal compounding device, and the polymer film is melted at high temperature to bond the aluminum films and the middle core layer together through the thermal compounding treatment of the first thermal compounding device and the second thermal compounding device 9. The aluminum-plastic panel after thermal compounding passes through the cooling roller set 410 and the cooling bellows 420 to lower the temperature of the aluminum-plastic panel, so that the aluminum-plastic panel is shaped. And then, by the traction of the tractor 14, the aluminum-plastic plate passes through the trimming roller set, and the two ends of the aluminum-plastic plate are trimmed by the trimming roller cutter. The trimmed aluminum-plastic plate passes through the tractor 14 and enters the plate shearing machine 15, the aluminum-plastic plate is cut to a proper size through the plate shearing machine 15, finally, the cut aluminum-plastic plate is stacked through the stacking machine 16, and then the aluminum-plastic plate is packaged and transferred.
Specifically, the raw material of the intermediate core layer is fed into the extruder 2, extruded through the extruder 2, passed through the second press roller 520 and the third press roller 530, passed around the second press roller 520 and through the second press roller 520 and the first press roller 510, passed around the first press roller 510 and passed through the stock guide roller, and advanced to the next process. Meanwhile, the polymer film is attached to both sides of the intermediate core layer by the first integrated guide roll 540 and the second integrated guide roll 550, and enters the three-roll calender 3 together with the intermediate core layer.
The rotation of the first rotating screw 514 is controlled by controlling the first driving motor 515, and the rotation of the first rotating screw 514 drives the first mounting member 511 to move up and down, so as to control the distance between the first pressing roller 510 and the second pressing roller 520, i.e. the thickness of the middle core layer can be controlled. In the process that the first pressing roller 510 moves upward, before the first pressing roller 510 collides with the second pressing roller 520, the first protection lever 523 abuts against the lower end of the second mounting member 521, so that the first pressing roller 510 does not collide with the second pressing roller 520.
By controlling the second driving motor 535, the rotation of the second rotating screw 534 is controlled, and the rotation of the second rotating screw 534 drives the third mounting member 531 to move up and down, so as to control the distance between the third pressing roller 530 and the second pressing roller 520, and thus the thickness of the intermediate core layer can be controlled. In the process that the third pressing roller 530 moves downward, before the third pressing roller 530 collides with the second pressing roller 520, the second protection rod 524 abuts against the upper end of the second mounting member 521, so that the third pressing roller 530 does not collide with the second pressing roller 520.
The first pressing roller 510 is controlled to rotate counterclockwise by a first shaping motor 513, the second pressing roller 520 is controlled to rotate clockwise by a second shaping motor 522, the third pressing roller 530 is controlled to rotate counterclockwise by a third shaping motor 533, and the rotation speeds of the first pressing roller 510, the second pressing roller 520 and the third pressing roller 530 are kept the same. In addition, when the adhesion between the middle core layer and the polymer film is not stable or when there is other risks, for example, a worker carelessly clamps hands between the first press roll 510, the second press roll 520 and the third press roll 530, the safety rope 572 transmits force to the pressure sensor 571 by pulling the safety rope 572, the pressure sensor 571 transmits a signal to the controller, and the three-roll calender 3 is powered off by the controller, so that unnecessary loss or personal injury is avoided.
Specifically, the raw material of the middle core layer produced by the aluminum-plastic plate is poured into the feeding hopper 310, the feeding motor is turned on, the feeding screw shaft 361 rotates to transfer the raw material into the stirring tank 300, the raw material is stirred by the stirrer 390, and the raw material is crushed by the crushing blade 391. Alternatively, the air pump 330 may be turned on, the air pressure in the blender jar 300 is reduced, and the raw material enters the feed box 320 through the feed pipe 322 and falls into the interior of the blender jar 300. Through visual window 380, can observe the crushing situation of raw and other materials, when raw and other materials crushing degree was enough, rotate unloading baffle 371, can pour the raw and other materials after smashing into in the feeder hopper 310, observe once more, when smashing incompletely, can send it into again smash in the agitator tank body 300. After the aluminum-plastic plate is completely crushed, the crushed aluminum-plastic plate can be poured into the feeding box 210, the feeding motor 230 is started, the screw shaft 221 rotates, the raw materials are fed into the feeding box, and the raw materials are extruded by the extruder 2, so that the aluminum-plastic plate can be prepared. In addition, the air exchange pump 350 is turned on to exchange air with the agitator tank 300, thereby preventing the heat in the agitator tank 300 from being too high.
