The thrust spring 13 is fixedly connected to the end of the adjusting screw pin 12. The movable side of the thrust spring 13 is in contact with the rear side of the material leveling scraper 2. The thrust spring 13 provides an elastic pre-tightening force to the material leveling scraper 2, ensuring that the material leveling scraper 2 can be close to the anilox roller when working, thereby improving the scraping uniformity of the material leveling scraper 2.

[0029] In order to provide a flipping and clamping force for the material-leveling scraper 2, a driving torsion spring 8 is arranged at the end of the spring clamp 3. The spring clamp 3 is flipped and installed on the side of the material box body 1 under the drive of the driving torsion spring 8.

In order to facilitate the rebound and reset of the clamping plate clamping block 9, a return spring is installed at the end of the clamping plate clamping block 9. In order to facilitate the flipping and clamping of the spring clamping plate 3 and the clamping plate clamping block 9, a pushing inclined surface is provided on the upper part of the side of the clamping plate clamping block 9.

After the material-distributing scraper 2 is installed, the edge of the material-distributing scraper 2 will extend beyond the edge of the spring clamp 3, but will not extend beyond the edge of the arc-shaped slot of the blocking foam 15. In this way, when the material box body 1 is against the anilox roller, the material-distributing scraper 2 in the middle part will fit with the anilox roller to scrape the material, and the blocking foam 15 and the material-distributing scraper 2 at the edge will fit tightly with the anilox roller to ensure that the edge of the material box body 1 does not leak material.

When the spring clamp plate 3 is flipped and closed, the side of the spring clamp plate 3 contacts the inclined surface on the upper side of the clamp plate clamping block 9, and the clamp plate clamping block 9 is retracted into the groove on the side of the feed box body 1 by pushing. Then, the clamp plate clamping block 9 rebounds and resets to clamp and limit the upper side of the spring clamp plate 3, completing the installation operation of the material-leveling scraper 2. Similarly, when disassembling, it is only necessary to move the clamping block 10 on the side of the clamp plate clamping block 9 to retract the clamp plate clamping block 9, and then pull up and flip the spring clamp plate 3 to complete the disassembly operation of the material-leveling scraper 2;

[0033] When the scraper is in use, the thrust spring 13 pushes the material-leveling scraper 2 close to the anilox roller to complete the scraping operation. At the same time, the working state of the material-leveling scraper 2 can be monitored in real time through the pressure signal fed back by the strain sensor 4, and the pressure signal fed back by the strain sensor 4 can be used as a reference for adjusting the material-leveling scraper 2. Then, the clamping force of the thrust spring 13 is controlled and adjusted by turning the adjusting screw 12 according to the signal reference to ensure that the material-leveling scraper 2 is in the best working state.

[0034] In summary, the material box adopts a clamping plate installation method for the material leveling scraper 2, and uses a spring clamping plate 3 to cooperate with the scraper limit block 6 to clamp and install the material leveling scraper 2.
