The doctor blade mechanism further includes a doctor blade pressing plate 10 arranged up and down. A locking screw 9 is rotatably arranged on the doctor blade cavity 12, the locking screw 9 is screwed with the doctor blade pressing plate 10, a guide plate 15 closely attached to one side of the doctor blade pressing plate 10 is arranged on the doctor blade cavity 12, an inclined pressing plate portion 14 is arranged on the other side of the doctor blade pressing plate 10, and the inclined pressing plate portion 14 can press the top and bottom doctor blades tightly on the doctor blade cavity 12. The doctor blade cavity 12 is arranged on a swing arm 24, one end of the swing arm 24 is sleeved on a support shaft 17, and a locking assembly is arranged corresponding to the doctor blade cavity 12.

[0018] Further, the support shaft 17 is arranged on a moving seat 2, the moving seat 2 is slidably arranged on the frame, a first cylinder 3 is arranged on the frame, a piston rod of the first cylinder 3 is connected with the moving seat 2. By adopting the above structure, the first cylinder 3 can be used to push the moving seat 2 so that the ink retaining block 7 on the doctor blade cavity 12 of the doctor blade mechanism is elastically pressed on the anilox roll with a proper pressure, which will neither affect the rotation of the anilox roll nor affect the doctor blade structure to closely adhere to the anilox roll for ink transfer and doctoring operations.

[0019] Further, the locking assembly includes a positioning seat 23 arranged on the doctor blade cavity 12, a positioning pin 21 is slidably arranged on the positioning seat 23, a locking arm 22 is arranged at one end of the positioning pin 21 in an extended manner, two locking grooves 20 for the locking arm 22 to be inserted into are arranged on the positioning seat 23 at intervals, one end of the positioning pin 21 can be inserted into a strip-shaped groove 16 on a positioning block 4, the positioning block 4 is slidably arranged on the moving seat 2 and is locked by a fastener. By adopting the above structure, when the overall angle of the doctor blade cavity needs to be adjusted, only the fastener on the positioning block 4 needs to be removed, and then the swing arm 24 is controlled to drive the doctor blade cavity 12 to swing to a proper angle. During the swinging process, the positioning pin 21 will move in the strip-shaped groove 16 of the positioning block 4 and drive the positioning block 4 to move on the moving seat 2, and then the positioning block 4 is fixedly connected to the moving seat 2 through the fastener, and the position of the doctor blade cavity 12 is locked through the cooperation of the positioning block 4 and the positioning pin 21. When the disassembly of components such as the doctor blade cavity 12 and the moving seat 2 is required, only the locking arm 22 needs to be controlled to disengage from the locking groove 20, and then the positioning pin 21 is pulled out of the strip-shaped groove 16 of the positioning block 4, and the separation between the moving seat 2 and the doctor blade cavity 12 can be realized.

[0020] Further, a fixing block 8 is connected to the doctor blade cavity 12. One end of the ink blocking block 7 is tightly pressed against the fixing block 8. A pressing block 6 is further included. The pressing block 6 is tightly pressed against the other end of the ink blocking block 7 through a pressing plate 5. The pressing plate 5 is fixed to the side end of the doctor blade cavity 12 through a fastener. With the above structure, the locking setting of the position of the ink blocking block 7 can be conveniently realized.

[0021] Further, a positioning step 25 that abuts against the upper doctor blade 11 and the lower doctor blade 13 is provided on the doctor blade cavity 12, which can facilitate the positioning and installation of the doctor blade.

[0022] The working principle of the present utility model is as follows: The first cylinder 3 pushes the moving seat 2 so that the ink blocking block 7 on the doctor blade cavity 12 of the doctor blade mechanism is elastically pressed against the anilox roll with a suitable pressure. Then, the ink is poured into the ink chamber through the ink inlet hole 18. The excess ink flows out from the ink outlet hole 19, and the ink in the ink chamber is transferred to the anilox roll. As the anilox roll rotates, the doctor blade will scrape off the excess ink on the anilox roll to complete the ink transfer and scraping operations. When the installation of the doctor blade is required, the doctor blade is inserted into the gap between the inclined pressing plate portion 14 and the doctor blade cavity 12, and then the locking screw 9 is controlled to rotate, driving the doctor blade pressing plate 10 to press the doctor blade tightly between the inclined pressing plate portion 14 and the doctor blade cavity 12; when the removal of the doctor blade is required, only the locking screw 9 needs to be controlled to drive the doctor blade pressing plate 10 to move along the guide plate 15, so that its inclined pressing plate portion 14 is far away from the doctor blade cavity 12, and at this time, the doctor blade can be conveniently withdrawn. When the overall angle position of the doctor blade needs to be adjusted, only the locking component of the doctor blade cavity needs to be loosened, and then the swing arm 24 is controlled to drive the doctor blade cavity 12 to swing to achieve angle adjustment. Then, the locking component is used to lock the doctor blade cavity to realize the positioning after the angle adjustment of the doctor blade cavity is in place.

[0023] With this structure of the present utility model, by cooperating with the setting of the guide plate and the locking screw, the lifting adjustment of the doctor blade pressing plate can be realized, and an inclined pressing plate portion is provided on the doctor blade pressing plate. By controlling the movement of the doctor blade pressing plate, the locking and positioning or loosening and removal of the doctor blade can be realized, which is very convenient to use; in addition, by integrally sleeving the doctor blade cavity on the support shaft, the overall swing adjustment of the doctor blade cavity can be realized, thereby realizing the precise cooperation with the anilox roll, and there is no need to adjust the position of the anilox roll anymore, making the overall adjustment of the equipment simpler and effectively improving the user experience.
