[0023] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail in conjunction with the drawings.

[0024] The present utility model provides a scratch-proof printing blade. By opening a receiving groove inside the housing and an opening groove at the bottom of the housing, the slide plate is located inside the receiving groove, the blade of the printing blade is located at the bottom of the slide plate and extends out from the opening groove. A spring is provided at the top of the blade of the printing blade, and the other end of the spring is connected to the slide plate. When there are particles on the plate roller, the particles pass through the blade of the printing blade and push the blade of the printing blade to move upward to compress the spring, converting the hard contact between the particles and the blade of the printing blade into elastic contact, preventing the blade of the printing blade from being damaged. When the particles are separated from the blade of the printing blade, the spring rebounds to drive the blade of the printing blade to reset, which does not affect the normal operation of the blade of the printing blade, and there is no need to frequently replace the printing blade, effectively improving the printing efficiency.

[0025] Figures 1-4Shown is a schematic structural diagram of an embodiment of a printing blade for preventing scratching of the present utility model. Please refer to Figures 1-4 In this embodiment, a printing blade for preventing scratching includes a housing 100, a lifting plate 200, and a limiting component 300.

[0026] An accommodation groove 110 is formed inside the housing 100, a slot 120 is formed at the bottom of the housing 100, the accommodation groove 110 communicates with the slot 120, a guiding groove 130 is formed on the side wall of the housing 100, the guiding groove 130 communicates with the accommodation groove 110, two fixing plates 140 are symmetrically installed on the side wall of the housing 100, a threaded rod 150 is rotatably connected between the two fixing plates 140, the top end of the threaded rod 150 extends out of the top of the fixing plate 140 and is provided with a knob 160.

[0027] The lifting plate 200 is located inside the accommodation groove 110. A connecting plate 210 is arranged at the bottom of the lifting plate 200. The bottom of the connecting plate 210 extends out from the bottom of the slot 120 and is provided with a scraping blade 220. A spring 230 is installed at the top of the scraping blade 220. The top end of the spring 230 is connected to the bottom of the lifting plate 200. A second guiding rod 240 is installed at the top of the connecting plate 210. A second guiding hole 250 is formed at the corresponding position of the top of the lifting plate 200 and the second guiding rod 240. The other end of the second guiding rod 240 penetrates through the second guiding hole 250 and is provided with a limiting plate 241. A guiding plate 260 is installed on the side wall of the lifting plate 200. The guiding plate 260 extends out of the guiding groove 130. A threaded hole 270 is formed at the top of the guiding plate 260. The threaded rod 150 rotates through the threaded hole 270. A guiding hole 280 is formed at the top of the guiding plate 260. A guiding rod 170 is installed between the two fixing plates 140. The guiding rod 170 penetrates through the guiding hole 280. When the scraping blade 220 needs to be used, rotate the knob 160 to drive the threaded rod 150 to rotate. Use the screw structure to push the guiding plate 260 to drive the lifting plate 200 to move downward. The lifting plate 200 pushes the connecting plate 210 and the scraping blade 220 to move downward. The connecting plate 210 and the scraping blade 220 extend out from the slot 120. When the particulate matter on the plate roller passes through the scraping blade 220, the particulate matter pushes the scraping blade 220 and the connecting plate 210 to move upward and compress the spring 230. The spring 230 converts the hard contact between the particulate matter and the scraping blade 220 into elastic contact to protect the scraping blade 220. When the particulate matter is separated from the scraping blade 220, the spring 230 rebounds to push the connecting plate 210 and the scraping blade 220 to move downward to reset, and the scraping blade 220 continues to work. When the scraping blade 220 does not need to be used, rotate the knob 160 to drive the threaded rod 150 to reverse. Use the screw structure to push the guiding plate 260 to drive the lifting plate 200 to move upward. The lifting plate 200 drives the connecting plate 210 and the scraping blade 220 to be retracted into the accommodation groove 110 to prevent accidental contact with the scraping blade 220 when not working, causing damage to the scraping blade 220.

[0028] The limiting component 300 includes a fixed frame 310 installed on the top of the housing 100, a sliding plate 320 slidably connected inside the fixed frame 310, a second spring 330 installed on the side wall of the sliding plate 320, and a limiting groove 340 opened on the other side wall of the sliding plate 320. What is not shown in the figure is that a circle of dense teeth is provided on the outer wall of the knob 160, and a circle of dense tooth grooves is opened on the inner wall of the limiting groove 340. When it is necessary to adjust the positions of the lifting plate 200 and the scraping blade 220, the sliding plate 320 is pulled to slide inside the fixed frame 310 and the second spring 330 is compressed. The knob 160 is separated from the inside of the limiting groove 340. The knob 160 is rotated to drive the threaded rod 150 to rotate, and the positions of the lifting plate 200 and the scraping blade 220 are adjusted. After the adjustment is completed, the sliding plate 320 is released. The second spring 330 rebounds to push the sliding plate 320 to reset. The knob 160 is embedded inside the limiting groove 340, and the teeth on the outer wall of the knob 160 are engaged with the tooth grooves on the inner wall of the limiting groove 340 to limit the knob 160 and prevent the lifting plate 200 and the scraping blade 220 from moving.
