Description

Technical Field

[0001] The invention relates to the technical field of flexographic printing equipment, and in particular to a tool-free quick-separation flexographic printing mechanism. Background Art

[0002] Flexographic printing is a direct printing method. It is called flexographic printing because it uses a flexible, raised image plate. The flexographic plate is fixed on the plate cylinder, and the plate is supplied with ink by a carved metal anilox roller. Since the flexographic plate has great elasticity, it can transfer liquid or grease ink to almost all types of materials. Flexographic printing is a light pressure printing method with unique flexibility and economy, and is beneficial to environmental protection. It meets the hygiene standards for food packaging printed products. Offset printing is relatively popular in my country, and gravure printing has also occupied a large market in the packaging industry. Flexographic printing technology started relatively late, but has developed rapidly.

[0003] The current flexographic printing mechanism has a strong structural integrity during operation and use, which makes it difficult to disassemble and repair it. In addition, the integral structure makes it difficult to produce the equipment, and the production cost and use cost increase accordingly. Therefore, we propose a tool-free quick-detachable flexographic printing mechanism. Summary of the invention

The side surface of the movable roller 20 is connected to a second gear 11. One end of the driving shaft 8 is connected to a first gear 9. The first gear 9 is meshed and connected with the second gear 11 to form a drive control. A screen roller 4 is arranged on the side of the printing plate 6. The screen roller 4 is adapted to the rubber roller 3 to form ink transfer. The bottom end of the printing plate 6 is connected to a first cylinder 13 to control the lifting and lowering operation of the printing plate 6 during installation.

[0029] Embodiment 2:

[0030] A scraper 5 is connected to one side of the ink fountain 2 of the tool-free quick-detachable flexographic printing mechanism, and the position of the scraper 5 is adapted to the anilox roller 4. The scraper 5 is used to evenly scrape the ink attached to the anilox roller 4. Support blocks 10 are installed on the two opposite inner surfaces of the body 1. The bottom end of the support block 10 is connected to the first cylinder 13. The support block 10 is adapted to the printing plate 6. The support block 10 is independently adjusted by the cylinder to control whether the printing plate 6 is in contact with the moving roller 20. When the support block 10 is lowered, the printing plate 6 does not contact the moving roller 20. This is the case when the flexographic printing mechanism is not in operation. When the support block 10 is raised, the printing plate 6 is attached to the moving roller 20. When the flexographic printing mechanism is in operation, bearings 12 are connected to the two opposite inner surfaces of the body 1. The position of the printing plate 6 is adapted to the bearing 12, and both ends of the printing plate 6 are in contact with the bearing 12. The third cylinder 15 is connected to the bottom end of the scraper 5, and the third cylinder 15 lifts and lowers the scraper 5 to control whether it contacts the anilox roller 4. Hooks 16 are arranged on the two opposite inner surfaces of the machine body 1, and latches 17 are connected at both ends of the anilox roller 4. The latches 17 are connected to the hooks 16 to install and fix the anilox roller 4. A controller 19 is installed on one surface of the machine body 1, and the controller 19 is electrically connected to the stepper motor 7. The stepper motor 7 is electrically controlled by the controller 19, and the operation is more automated. Pin grooves are arranged on the two opposite inner surfaces of the machine body 1, and the two ends of the printing plate 6 are adapted to the position of the pin grooves, and the printing plate 6 and the pin grooves are slidably matched, so that the printing plate 6 cooperates with the first cylinder 13 to lift and lower.

[0031] It should be noted that the present invention is a tool-free quick-separation flexographic printing mechanism. During operation, the ink fountain 2 is first used to store ink, and the ink is attached to the anilox roller 4 by the rubber roller 3. A scraper 5 is installed at the adaptable position of the rubber roller 3 on one side of the ink fountain 2 to scrape the ink attached to the anilox roller 4 evenly and scrape off excess ink. Then, the ink on the anilox roller 4 contacts the printing plate 6, and a pattern is engraved on the printing plate 6. The ink is attached to the pattern. The plate drum receiving the printing plate 6 rotates during operation to print the pattern on paper. The present invention is a quick separation mechanism. When separating, no related tools are needed, and the corresponding cylinders of the mechanism can be disassembled. The bottom sides of both ends of the printing plate 6 are connected to the first cylinder 13, and the first cylinder 13 buckles and locks the printing plate 6. The ink fountain 2 uses the second cylinder 14 to form a lifting effect. When the machine is not in use, it does not contact the anilox roller 4, etc., and no inking will be formed. The bottom end of the scraper 5 is connected to the third cylinder 15 to control whether it contacts the anilox roller 4. The three groups of cylinders respectively control different operating function mechanisms, so that the flexographic printing mechanism can be quickly separated in a tool-free state, and the operation is more convenient.
