[0018] like Figure 1 The scraper clamping device shown includes a main shaft 1 and a base plate 8. A plurality of cylinder connecting plates 2 are arranged on the main shaft 1. Each cylinder connecting plate 2 is connected to a cylinder 3 through a rotating shaft. The piston rod of each cylinder 3 is connected to a clamping seat 4 through a rotating shaft. The clamping seat 4 is connected to the base plate 8 through bolts. The base plate 8 is connected to the scraper 9 through bolts. The clamping seat 4 is connected to the main shaft 1 through a bearing seat 5. A bearing is arranged in the bearing seat 5. Since there are relatively few bolts for fixing on the base plate 8, while there are more bolts for fixing on the scraper 9, when disassembling and assembling the scraper 9, the base plate 8 is directly disassembled and assembled together, which can not only ensure the stability of the scraper 9, but also improve the convenience of disassembly and assembly.

[0019] A plurality of support blocks 10 are arranged on the bottom plate 8. The support block 10 is a Z-shaped metal block, one end of which is open to support the scraper 9, and the other end is connected to the bottom plate 8 by bolts. The open end of the support block 10 clamps the scraper 9, which facilitates the fixed connection and positioning of the scraper 9 and the bottom plate 8, and can prevent the scraper 9 from loosening and displacement during operation, providing multi-directional support for the scraper 9.

[0020] The bottom plate 8 is provided with a plurality of sliders 7 at its edge, the sliders 7 are against the bottom plate 8, the bottom of the sliders 7 are connected to the clamping seat 4 through a slide rail, the sliders 7 can move forward and backward along the slide rail, a groove is provided on the bottom plate 8 and the sliders 7, a bolt passes through the groove and is connected to the clamping seat 4, and one end of the slider 7 is connected to the clamping seat 4 through an adjusting screw 6. The adjusting screw 6 adjusts the front and rear positions of the sliders 7 and the bottom plate 8 on the clamping seat 4, the bolts are fixed after the bottom plate 8 is positioned, and the plurality of clamping seats 4 serve as supporting components between the scraper 9 and the main shaft 1, which can provide a guarantee for the uniform support of the entire scraper 9.

[0021] like Figure 2 As shown, the cylinder connecting plate 2 includes a main shaft section 21, a connecting section 22 and a cylinder section 23. The main shaft section 21 is provided with an axial hole 24, and the main shaft 1 passes through the axial hole 24. The bottom of the main shaft 21 is connected to the cylinder section 23 through the connecting section 22. The cylinder section 23 and the main shaft section 21 are perpendicular to each other. The connecting section 22 is tilted and is set at an obtuse angle to the angle between the main shaft section 21 and the cylinder section 23. A screw is provided on the main shaft section 21 to connect with the main shaft 1, so that the cylinder connecting plate 2 is fixed at a desired position. The structure of the cylinder connecting plate 2 can reduce the pressure on the main shaft 21 while providing support for the cylinder 3. At the same time, it occupies less space and avoids protruding parts from scratching the passing printing materials.

[0022] The scraper 9 is provided with a plurality of handles 11 for easy carrying when the scraper 9 and the bottom plate 8 are disassembled together.

[0023] The slider 7 is movably connected to the base plate 8, and the movable connecting parts are bolts, plug-in blocks, etc. When the slider 7 moves, it can drive the base plate 8 to move, and when the base plate 8 is disassembled, it can be quickly separated from the slider 7.
