The positioning plate 422 is slidably connected to the roller 320.

[0044] The distance adjustment component 520 includes a screw rod 521, a fixed rod 522, a slider 523 and a handle 524; the screw rod 521 is rotatably installed on the upper side of the mobile platform of the servo mobile platform 510, the fixed rod 522 is fixedly installed on the upper side of the mobile platform of the servo mobile platform 510, the slider 523 is slidably connected to the fixed rod 522 and is threadedly connected to the screw rod 521 through a threaded sleeve, and a handle 524 is fixedly installed at the front end of the screw rod 521.

[0045] The clamping assembly 530 includes a connecting plate 531, a second cylinder 533 and a parallel cylinder 532; the second cylinder 533 is fixedly installed on the second slider 523, the second cylinder 533 is fixedly installed on the moving platform of the servo moving platform 510, and the output end of the second cylinder 533 is fixedly connected to the connecting plate 531; the parallel cylinders 532 are fixedly installed near the ends of the two connecting plates 531.

[0046] In the present invention, the sheet is placed on the roller 320, and the bidirectional threaded rod 414 is driven to rotate by turning the handle 411. The rotation of the bidirectional threaded rod 414 drives the two sliders 412 to move synchronously under the limit of the fixed rod 413, thereby increasing or decreasing the distance between the two positioning plates 422; turning the handle 2 524 drives the screw rod 521 to rotate, and the rotation of the screw rod 521 drives the slider 2 523 to move under the limit of the fixed rod 2 522, thereby increasing or decreasing the distance between the two groups of parallel cylinders 532; starting the cylinder 1 421 and using the connecting rod 423 to make the two positioning plates 422 approach the sheet synchronously from the left and right ends at the same time; at the same time, starting the cylinder 2 533 makes the two groups of parallel cylinders 532 approach the sheet synchronously from the front and rear ends, and move the sheet to the center of the two side plates 310, so as to realize the centering alignment of sheets of different specifications;

[0047] Start the parallel cylinder 532 at the front end of the coating machine 200 to clamp the sheet, and the cylinder 2 533 at the rear end of the coating machine 200 drives the parallel cylinder 532 at the rear end to reset; start the stepper motor of the servo mobile platform 510 to drive the mobile platform to move horizontally backward as a whole to approach the coating machine 200; the parallel cylinder 532 pushes the sheet to roll on the surface of multiple rollers 320 to the coating machine 200, and the coating machine 200 applies film to the sheet in one direction from the rear end of the sheet; when the film is applied to the middle of the sheet, start the cylinder 2 533 at the rear end of the sheet to make the parallel cylinder 532 clamp the sheet from the rear end of the sheet, and at the same time, the parallel cylinder 532 at the front end releases the sheet and resets it through the slider 2 523 to prevent the parallel cylinder 532 at the front end from reaching The rear parallel cylinder 532 releases the sheet material to reset and stops moving; after the sheet material is rotated ninety degrees by the rotating mechanism 600, the sheet material can be coated on the other direction by the coating machine 200, and the rear parallel cylinder 532 re-clamps the sheet material, and the mobile platform drives the sheet material back to the coating machine 200 for secondary coating. When the coating reaches the middle of the sheet material again, the front parallel cylinder 532 re-clamps the sheet material, and the rear parallel cylinder 532 releases the sheet material to reset, preventing the rear parallel cylinder 532 from reaching the coating machine 200 to hinder the coating of the sheet material. After the secondary coating is completed, the sheet material can be coated in all directions.

[0048] In the utility model, by adjusting the handle 411 under the action of the positioning plate 422 and adjusting the handle 2 524 under the action of the parallel cylinder 532, the device can be centrally positioned for sheets of various specifications. After the sheets are coated once, the sheets are rotated under the action of the rotating mechanism 600, so that the film coating machine 200 can coat the sheets for a second time in another direction; all-round automatic coating of sheets of various specifications is achieved, which speeds up the coating efficiency and facilitates operation.

[0049] The rotating mechanism 600 includes a cylinder 3 620, a rotating cylinder 630 and an electromagnet 610.

[0050] In the present invention, after the sheet material is coated once, the parallel cylinder 532 at the rear end releases the sheet material to reset. When the mobile platform stops moving, cylinder three 620 is started to push the rotating cylinder 630 and the electromagnet 610 close to the upper end of the sheet material. The electromagnet 610 is energized to make the sheet material leave the surface of the roller 320 and adsorb on the surface of the electromagnet 610. The rotating cylinder 630 is started to drive the sheet material to rotate ninety degrees through the electromagnet 610. The electromagnet 610 is powered off to make the sheet material leave the surface of the electromagnet 610 and fall back on the surface of the roller 320. Cylinder three 620 drives the rotating cylinder 630 and the electromagnet 610 to reset as a whole, completing the rotation of the sheet material, so that the coating machine 200 can coat the sheet material for a second time in another direction, thereby realizing all-round coating.
