A kind of electrochemical aluminum stamping foil production coating machine

Abstract

This utility model discloses a coating machine for electroplated aluminum hot stamping foil production, relating to the field of electroplated aluminum hot stamping foil production technology. It includes a negative pressure workbench with a mounting frame on top. An electric telescopic rod is fixedly installed inside the top of the mounting frame. The advantages of this utility model are: the amount of adhesive used in a single coating can be quantitatively controlled through the feeding box, effectively avoiding waste caused by excessive adhesive application; and the adhesive can be evenly coated on one side of the feeding box through the discharge nozzle, ensuring uniform coating and improving coating uniformity. By reversing the servo motor, hydraulic oil in the piston cylinder is drawn into the hydraulic cylinder through the connecting pipe, thereby driving the second piston plate, connecting rod, and third piston plate to reset. When the third piston plate resets, a negative pressure is generated in the feeding box, allowing adhesive from the storage tank to be drawn into the feeding box for storage through the feeding pipe, thus achieving automatic feeding and facilitating production processing.

Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum hot stamping foil production technology, specifically to an electroplated aluminum hot stamping foil production coating machine. Background Technology

[0002] Electroplated aluminum hot stamping foil is a thin-film material used for heat transfer printing. It is made by coating several layers of different functional coatings on the surface of a plastic film and vacuum-depositing an aluminum layer. It is widely used in the post-printing processing of paper and plastics. In recent years, the combination of laser holographic anti-counterfeiting technology and printing processes has led to rapid development in the packaging and printing industry. Electroplated aluminum hot stamping foil is widely used in printing and packaging, and the coating machine is one of the important pieces of equipment in the hot stamping foil production line.

[0003] Currently, existing electroplated aluminum hot stamping foil coating machines cannot perform quantitative coating during the coating process, which easily leads to uneven coating with either too much or too little glue in some areas, thus having certain shortcomings. To address this, we have proposed an electroplated aluminum hot stamping foil coating machine. Utility Model Content

A discharge check valve 9 is installed. A mounting cover 10 is fixedly installed on the top of the mounting plate 4. A servo motor 11 is fixedly installed on one side of the mounting cover 10. A lead screw 12 is fixedly installed on the inner side of the mounting cover 10, extending from the output end of the servo motor 11. A sleeve block 13 is threaded on the outer side of the lead screw 12. The sleeve block 13 has a hole that mates with the lead screw 12. The sleeve block 13 is slidably connected to the inner wall of the mounting cover 10. A hydraulic cylinder 14 is fixedly installed on the top of the mounting plate 4 and on one side of the mounting cover 10. A hydraulic rod 15 is slidably installed inside one end of the hydraulic cylinder 14. One end of the pressure rod 15 is fixedly connected to the sleeve block 13, and the other end of the hydraulic rod 15 is fixedly installed with a first piston plate 16. A connecting pipe 17 is installed inside the other end of the hydraulic cylinder 14. A piston cylinder 18 is fixedly installed on the top of the feeding box 6. One end of the connecting pipe 17 is fixedly connected to the top of the piston cylinder 18. Hydraulic oil is provided inside the hydraulic cylinder 14. The connecting pipe 17 communicates with the interiors of the hydraulic cylinder 14 and the piston cylinder 18. A second piston plate 19 is movably installed inside the piston cylinder 18. A connecting rod 20 is fixedly installed at the bottom of the second piston plate 19. One end of the 0 extends into the interior of the feeding box 6 and is fixedly installed with a third piston plate 21. The third piston plate 21 is slidably connected to the inner wall of the feeding box 6. Two storage boxes 22 are fixedly installed on the top of the mounting frame 2. The top of the storage box 22 is provided with a feeding port. A sealing cap is threaded on the top of the feeding port. A feeding pipe 23 is provided at the bottom of one side of the storage box 22. One end of the feeding pipe 23 extends into the interior of the feeding box 6. A feed check valve 24 is provided inside the feeding pipe 23. The feeding pipe 23 is reserved with a certain length so that it can cooperate with the lifting of the feeding box 6.

[0017] Two guide rods 25 are fixedly installed on the top of the mounting plate 4. The guide rods 25 are slidably connected to the inside of the mounting bracket 2. The function of the guide rods 25 is to limit and guide the mounting plate 4.

[0018] Linear guide rails 26 are provided on both sides of the negative pressure worktable 1. An electric slider 27 is slidably installed on the outer side of the linear guide rails 26. The mounting frame 2 is fixedly connected to the electric slider 27. The negative pressure worktable 1 has a negative pressure function, which can make the substrate to be coated with adhesive be adsorbed on the negative pressure worktable 1, thereby improving the stability of the substrate during subsequent coating. The linear guide rails 26 and the electric slider 27 are existing technologies. They can drive the mounting frame 2 to move back and forth stably on the negative pressure worktable 1. A PLC controller is provided on one side of the mounting frame 2, and the electric telescopic rod 3, servo motor 11 and electric slider 27 are all electrically connected to it.

[0019] In summary, when using this electroplated aluminum hot stamping foil production coating machine, the substrate to be processed is first placed on the negative pressure worktable 1 and laid flat. The substrate is then adsorbed and fixed by the negative pressure. Subsequently, the electric telescopic rod 3 is activated by the PLC controller to push the mounting plate 4 down so that the coating roller 5 can cooperate with the substrate. Then, the servo motor 11 is activated by the PLC controller to drive the lead screw 12 to rotate. The thread on the outside of the lead screw 12 drives the sleeve block 13 to move, which in turn drives the hydraulic rod 15 and the first piston plate 16 to move. This squeezes the hydraulic oil in the hydraulic cylinder 14, which then enters the piston cylinder 18 through the connecting pipe 17. The hydraulic oil then squeezes the second piston plate 19, which pushes the second piston plate 19 and the connecting rod 20 down. After the connecting rod 20 moves down, it pushes the third piston plate 21 down, thus pressing down the coating roller 5. The glue in the feeding box 6 is squeezed out to the bottom of the partition plate 8 through the discharge check valve 9 and then discharged to the outside of the coating roller 5 through the discharge nozzle 7. Finally, the electric slider 27 moves on the outside of the linear guide rail 26, which drives the mounting frame 2 to move so that the coating roller 5 can evenly apply the glue to the substrate. After the coating is completed, the PLC controller controls the electric telescopic rod 3 to drive the mounting plate 4 to reset and then turns on the servo motor 11 to reverse, so that the hydraulic oil in the piston cylinder 18 is drawn into the hydraulic cylinder 14 through the connecting pipe 17, thereby driving the second piston plate 19, the connecting rod 20 and the third piston plate 21 to reset. When the third piston plate 21 resets, a negative pressure is generated in the feeding box 6, and then the glue in the storage box 22 can be drawn into the feeding box 6 through the feeding pipe 23 for storage, thereby realizing the automatic feeding function and facilitating its production and processing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
