Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a printing scraper return device with an ink-drip-proof function. Background Art

[0002] The scraper on the printing press is an indispensable component for ink printing. It is controlled by the drive unit on the printing press to press down and move, scraping the ink horizontally onto the printed material to complete the covering printing. During the printing process, the scraper will inevitably adhere to the ink material because of its direct contact with the ink.

[0003] Nowadays, printing scrapers are generally of vertical structure. The ink adhered to the scraper is easy to drip and contaminate the printed object. If it is designed with a fixed inclined structure to avoid the trouble of ink dripping, it cannot be restored to the original vertical structure after printing is completed. Firstly, it is inflexible to use, and secondly, it is easy to cause structural damage.

[0004] Therefore, in view of the fact that the above-mentioned existing scraper designed with an inclined structure can avoid ink dripping, but cannot be reset to a vertical state and is inflexible to use, a printing scraper with a return mechanism can be designed. By flexibly adjusting the scraper angle, it can not only avoid ink dripping, but also return to the original vertical state in time after printing is completed. Utility Model Content

[0027] See also Figure 5In this embodiment, the return mechanism includes a movable support 701, a driving machine 702, a fixed support 703, and a push frame 704; the movable support 701 is fixedly installed on one side of the upper end of the panel 2 by bolt anchoring, the driving machine 702 is movably installed on the movable support 701 through a pin structure, the piston rod of the driving machine 702 is fixedly connected to the push frame 704 with an axis hole at the end, the fixed support 703 is fixedly connected to the back plate 3 and the upper end of the fixed support 703 is provided with a shaft head, and the push frame 704 is fixedly connected to the back plate 3. 04 is movably connected to the fixed support 703 through the shaft hole and the shaft head. The driving machine 702 can use devices such as cylinders, oil cylinders, screw motors, etc. to control the movement of the pushing frame 704 to generate a pushing force on the fixed support 703. The reaction force generated by this pushing force is due to the movable connection between the driving machine 702 and the movable support 701, and the movable connection between the fixed support 703 and the pushing frame 704, so that the No. 1 beam 1 and the panel 2 above it, and the scraper assembly below are flipped together to adjust the angle.

[0028] See also Figure 6 In the present embodiment, the ink return knife assembly comprises a No. 2 rail 901, an ink return knife body 902, and a baffle 903; the No. 2 rail 901 is buckled and installed at the lower end of the No. 2 beam 8, and the ink return knife body 902 is fixedly installed at the lower end of the No. 2 rail 901, and baffles 903 are arranged on the left and right sides of the ink return knife body 902, and the two baffles 903 are in an eight-shaped opening shape, and the upper end of the No. 2 rail 901 is a U-shaped structure, which is snapped on the bottom wall of the No. 2 beam 8, and the ink return knife assembly moves with the No. 1 beam 1, and the ink return knife body 902 pushes the excess ink back to the starting point of printing. When pushing the ink, the baffle 903 is used to block the ink overflowing to the two sides of the ink return knife body 902 to prevent it from flowing around.

[0029] When the printer is working, the driving unit on the printing press controls the first beam 1 to move downward, and at the same time, the driving machine 702 is started to control the push frame 704 to move, generating a push force on the fixed support 703. The reaction force generated by the push force is due to the movable connection between the driving machine 702 and the movable support 701, and the movable connection between the fixed support 703 and the push frame 704, so that the first beam 1 and the panel 2 above it, and the scraper body 602 below are turned over together, and the angle is adjusted to be inclined, so that the scraper body 602 is against the printed material and contacts with the ink;

[0030] The printing press drives the first beam 1 and the second beam 8 to move horizontally synchronously, and the scraper body 602 scrapes the ink flat and covers it on the printed material. Then the first beam 1 is driven up by the printing press, and at the same time, the second beam 8 moves down, so that the ink return blade body 902 is against the printed material.

[0031] The first beam 1 and the second beam 8 move in the opposite direction, and the ink return knife body 902 scrapes the excess ink on the printed material back to the original ink supply position, and reciprocating printing is performed according to this process.

[0032] Through the above steps, the scraper assembly is controlled to be in an inclined state during printing by setting a return mechanism on the original printing machine scraper beam. Compared with the traditional vertical structure, it can effectively prevent ink dripping. After printing, the scraper assembly can also be controlled to return to the center. Compared with the existing printing scraper with a fixed inclination angle that cannot be returned to the center, it is more flexible to use and can avoid the scraper assembly being easily damaged due to the tilted structure in the idle state. This solves the problem that the existing scraper designed with an inclined structure can avoid ink dripping but cannot be reset to a vertical state and is inflexible to use.
