Description

Technical Field

[0001] The present invention belongs to the technical field of coating composite processing, and in particular relates to a multi-process different-path coating composite method and equipment. Background Art

[0002] Many existing factories need to purchase multiple equipment to meet the process requirements of various coating and compounding processes, which is not only expensive but also occupies a large area.

[0003] For example, the patent application number CN201811443432.4 is a coating and compounding equipment, which includes a main unloading device, a coating device, a baking device, a secondary unloading device, a compounding device and a winding device. After the substrate film is unloaded from the main unloading device, it passes through the corona device and the dust-binding device in sequence and enters the first coating mechanism or the second coating mechanism in the coating device for glue coating. The substrate film coated with glue enters the heating channel of the baking device. The substrate film output from the heating channel and the release film unloaded from the secondary unloading device enter the compounding device together for compounding. The composite film formed after compounding passes through the storage device and enters the winding device for winding. However, this device cannot meet the needs of various coating and compounding processes, and the oven does not have a dehumidification device and an automatic feeding device, so the drying effect and work efficiency are low.

[0013] Furthermore, in S2, when the first substrate passes through the anilox roller coating device, the plate coating chamber scraper provided in the anilox roller coating device scrapes off excess and irregular solvent on the first substrate, and is detected and adjusted by the registration device so that each part of the printed pattern is accurately printed on the specified area of the first substrate. After being dried in the oven, it is pulled out by the pulling device and cooled by the cooling device.

[0014] Furthermore, in S2, when the first substrate passes through the anilox roller coating device, the plate coating chamber scraper provided in the anilox roller coating device scrapes off excess and irregular solvent on the first substrate.

[0075] The working principle of the above technical solution is as follows: the substrate passes through multiple guide rollers 502 and is connected to the reel rod 522, the motor 3 513 is started to drive the inner rod 1 514 to rotate, drive the slide rod 1 515 to rotate, drive the turntable 1 516 to rotate through the gear meshing transmission, drive the turntable 2 518 to rotate through the belt 2 517, drive the inner rod 2 519 to rotate, drive the reel rod 522 to rotate, drive the substrate to be rolled into the substrate reel 523, the empty tube 524 contacts the substrate reel 523, drive the empty tube 524 to rotate, drive the empty tube 524 to squeeze out the bubbles in the substrate reel 523, and prevent the substrate reel 523 from loosening. As the diameter of the substrate reel 523 continues to increase, it drives the slide rod 2 525 to move toward the outer shaft 1 511, driving the spring 2 5 26 is compressed, driving the connecting rod 2 527 to rotate, driving the slider 1 528 to slide toward the center of the outer shaft 1 511, and the slider 1 528 contacts the disc 533, driving the spring 3 532 to be compressed. When the spring 3 532 is compressed to a certain extent, the small ball 536 will be squeezed into the chamber of the outer shaft 1 511, and the spring 4 537 is compressed, and the slide rod 1 515 slides to the other end, and the slide rod 1 515 is separated from the previous rotating wheel 1 516 and meshes with the gear of another rotating wheel 1 516, thereby stopping the rotation of the inner rod 2 519, causing the substrate reel 523 to stop rotating, and at the same time driving the reel rod 522 opposite to the substrate reel 523 to rotate, starting the motor 2 509 to drive the outer shaft 1 511 to rotate counterclockwise through the belt 1 510, driving The four-leaf bracket 512 rotates counterclockwise, the outer shaft 511 rotates 180 degrees, the support rod 540 lifts the substrate, the heat fuse 508 can heat the thermal fuse 507, the starting motor 503 drives the rotating shaft 504 to rotate, drives the connecting rod 1 505 to rotate with the rotating shaft 504 as the axis, drives the roller 1 506 to press the substrate onto the reel rod 522, and there is glue on the reel rod 522, so that the substrate quickly sticks to the reel rod 522. At the same time, the thermal fuse 507 quickly melts the substrate, and the substrate is quickly rolled on the reel rod 522, thereby completing the winding and rewinding work. The ratchet 541, the pawl 542 and the spring 5 543 form a reverse-stop device to prevent the substrate reel 523 from reversing when the four-leaf bracket 512 rotates. The motor 4 538 drives the connecting plate 539 to move outward, driving the inner rod 2 519 to slide outward on the rotating wheel 2 518, driving the spring 1 521 to be compressed, driving the two inner rods 2 519 to separate from the reel rod 522, and then the reel rod 522 and the substrate reel 523 can be removed, and the new reel rod 522 is placed between the two inner rods 2 519. The front ends of the two inner rods 2 519 slide into the reel rod 522. Since the elastic plate 520 is squeezed and deformed, the friction between the inner rod 2 519 and the reel rod 522 is increased, preventing the reel rod 522 from sliding. The screw 1 530 is rotated to drive the slider 3 531 to slide in the slider 2 529, driving the spring 3 532 and the disk 533 to move, thereby changing the distance between the slider 1 528 and the disk 533.The diameter of the substrate reel 523 is then changed, and the position of the pointer 535 on the slider 3 531 on the scale bar 534 corresponds to the diameter of the substrate reel 523.

[0076] The beneficial effects of the above technical solution are: no need to stop the machine to change rolls, high degree of automation, improved work efficiency, and reduced labor costs; the diameter of the roll can be changed according to actual needs.
