Problems solved by technology

The clamping structure of the existing scraper is relatively complicated, the disassembly of the knife holder is inconvenient, and it takes a long time to replace the blade
The scraper clamping mechanism of the existing printing machine is that the upper and lower clips are connected and pressed by a row of bolts. It is inconvenient to replace the blade and it is not easy to operate.

Embodiment Construction

[0025] The present invention is described in detail below in conjunction with accompanying drawing:

[0026] A scraper device for a printing machine, comprising a frame 1, on which a fixed plate 2 is fixed, and a linear track 21 is horizontally arranged below the fixed plate 2, and the number of the linear tracks 21 is 4. To the positions of the four corners below the fixed plate, a reciprocating plate 3 that can move left and right along the linear track 21 is provided, and a left and right movement mechanism 4 that makes the reciprocating plate 3 move left and right is provided on the frame 1. 3 is provided with a scraper assembly 5 and an up and down movement mechanism 6 for controlling the movement of the scraper assembly 5 up and down, and a front and rear movement mechanism 7 for controlling the movement of the scraper assembly 5 back and forth. The linear guide rail is used to realize the left and right movement and up and down movement, with small gap, high precision, ...

Abstract

The invention relates to a printer scraper device. The printer scraper device comprises a frame, the frame is fixedly provided with a fixing plate, a linear track is horizontally arranged below the fixing plate, the linear track is provided with a reciprocating plate capable of moving along the linear track in a left-right mode, the frame is provided with a left-right movement mechanism enabling the reciprocating plate to move in a left-right mode, the reciprocating plate is provided with a scraper assembly, a vertical movement mechanism controlling the scraper assembly to move vertically and a back-forth movement mechanism controlling the scraper assembly to move back and forth. The printer scraper device is stable, the overall movement of the scraper such as left-right movement and lifting are achieved through a linear guide rail, the left-right movement of a scraper is controlled through the motor, the vertical movement of the scraper is achieved through worms and gears, the back and forth adjustment of the scraper is achieved through a screw rod, thus adjustment of the scraper in three directions can be achieved, and influences of gap between gears and racks on scraper stability can be reduced; by means of the leverage principle, a clamping mechanism of the scraper blade can achieve clamping or unclamping of the scraper blade quickly through an eccentric shaft, and a scraper clamp needs not to be detached during scraper replacement.

Description

[0001] 【Technical field】 [0002] The invention relates to equipment for a printing machine, in particular to a scraper device for a printing machine. [0003] 【Background technique】 [0004] The scraper part is the main mechanism of the gravure printing machine. The function of the scraper is to scrape off unnecessary ink from the printing plate, so that the ink with graphics and text can be clearly transferred to the printed material. The quality of scraper parts often determines the quality of printed products, so scraper is very important to the whole printing machine. The clamping structure of the existing scraper is relatively complicated, the disassembly of the knife holder is inconvenient, and it takes a long time to replace the blade. The scraper clamping mechanism of the existing printing machine is that the upper and lower clips are connected and pressed by a row of bolts. It is inconvenient to replace the blade and it is not easy to operate. The structure of the i...
