[0007] Preferably, two through holes are provided on the upper portion of the sliding block, and two screw rods are connected to one end of the cleaning block. The two screw rods pass through the through holes and are fastened by nuts.

[0008] In the above technical solution, the cleaning block is connected to the slider via a screw, so that the cleaning block can be easily replaced.

[0009] Preferably, the knife seat is provided with an L-shaped notch, the outer edge of the notch is hinged with a pressure plate, the pressure plate, the scraper and the notch are all provided with screw holes, and the scraper is connected to the gap formed by the pressure plate and the notch by bolts.

[0010] In the above technical solution, the scraper is connected to the knife holder by bolts, which is convenient for disassembly and replacement. Since the pressure plate is hinged on the knife holder, there is no need to remove the pressure plate when replacing the scraper. You only need to unscrew the bolts first, and then flip the pressure plate outward to remove the scraper. Since the pressure plate is long and heavy, it is easy to cause danger. Therefore, the scraper can be replaced without removing the pressure plate, which improves efficiency and reduces the occurrence of danger.

[0011] Preferably, one end of the knife holder away from the scraper is connected to a plurality of cylinders, the ends of the cylinders are connected to mounting plates, and screw holes are provided on the mounting plates.

[0012] The above technical solution can install the utility model on a printing machine through a mounting plate, so that the scraper is located on the upper part or the side of the printing roller. The cylinder is extended to drive the scraper to move closer to the printing roller, so that the ink on the printing roller can be cleaned by the scraper.

[0013] Preferably, one side of the cleaning groove is a straight edge matching one side of the scraper, and the other side of the cleaning groove is a bevel edge matching the other side of the scraper.

[0014] In the above technical solution, since the scraper has a cutting edge, the cleaning groove is set to a straight edge and a bevel edge matching the cutting edge, so that the cutting edge of the scraper can be fully cleaned.

[0015] Preferably, a foam brush is fixed to the inner wall of the cleaning tank.

[0016] In the above technical solution, the foam brush can achieve a better cleaning effect on the scraper without causing damage to the scraper.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] When there is too much ink on the scraper or the ink is dry, start the motor to drive the screw to rotate, which can drive the slider to slide on the guide rod, thereby driving the cleaning block to move toward the scraper. During the movement of the cleaning block, the end face of the scraper enters the cleaning groove, and the scraper is cleaned through the contact between the cleaning groove and the scraper. No manual cleaning is required, which reduces the occurrence of danger and improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The scraper 2 is connected to the blade holder 1 by bolts, which is convenient for disassembly and replacement; since the pressing plate 15 is hingedly connected to the blade holder 1, when replacing the scraper 2, it is not necessary to remove the pressing plate 15, and the scraper 2 can be removed by first unscrewing the bolts and then flipping the pressing plate 15 outwards. Since the pressing plate 15 is long and heavy, it is easy to cause danger, so the scraper 2 is replaced without removing the pressing plate 15, which improves efficiency and reduces the occurrence of danger.

[0026] One end of the knife seat 1 is connected to a fixed block 3, and the back of the fixed block 3 and the back of the other end of the knife seat 1 are connected to a bearing seat 4, and the two bearing seats 4 are rotatably connected with a screw rod 5, and the two bearing seats 4 are fixedly connected with a guide rod 6, and the screw rod 5 is threadedly connected with a slider 7, and the slider 7 is slidably connected to the guide rod 6. The side of the slider 7 facing the scraper is detachably connected with a cleaning block 8, and the side of the cleaning block 8 facing the scraper is provided with a cleaning groove 9 for accommodating the scraper to pass through, one side of the inner wall of the cleaning groove 9 is a straight edge matching one side of the scraper 2, and the other side of the inner wall of the cleaning groove 9 is a bevel edge matching the other side of the scraper 2, so that the cleaning groove 9 and the scraper 2 can be fully contacted, and a motor 10 is provided on one side of the fixed block 3, and the motor 10 is transmission-connected to the screw rod 5 through a coupling, and the cleaning block 8 can be moved from one end of the scraper 2 to the other end by driving the slider 7 to move on the screw rod 5.

[0027] like Figure 3As shown, two through holes 11 are provided on the upper part of the slider 7, and two screws 12 are connected to one end of the cleaning block 8. The two screws 12 pass through the through holes 11 and are fastened by nuts 13. The cleaning block 8 is connected to the slider by the screws 12, so that the cleaning block 8 can be replaced easily.

[0028] The end of the blade holder 1 away from the scraper is connected to a plurality of cylinders 16, and the end of the cylinder 16 is connected to a mounting plate 17, and the mounting plate is provided with screw holes. The utility model can be installed on a printing machine through the mounting plate 17, so that the scraper 2 is located on the upper part or the side of the printing roller, and the extension of the cylinder 16 can drive the scraper 2 to move closer to the printing roller, so that the ink on the printing roller can be cleaned by the scraper.

[0029] The working principle of this embodiment is: when there is too much ink on the scraper 2, or the ink is dry, the motor 10 is started to drive the screw 5 to rotate, which can drive the slider 7 to slide on the guide rod 6, thereby driving the cleaning block 8 to move toward the scraper 2. During the movement of the cleaning block 8, the end face of the scraper 2 enters the cleaning groove 9, and the scraper 2 is cleaned through the contact between the cleaning groove 9 and the scraper 2. No manual cleaning is required, which reduces the occurrence of danger and improves efficiency.
