[0018] As shown in the figure, the semi-closed scraper mechanism of the adjustable flexographic printing press disclosed by the present invention includes an ink chamber body 8, an ink chamber 3 is provided on the ink chamber body 8, an ink inlet hole 22 connected to the ink chamber 3 is provided on the upper rear side of the ink chamber body 8, sealing blocks 7 are provided on both sides of the ink chamber 3, an upper scraper 10 and a lower scraper 6 are installed on the ink chamber body 8, a strip-shaped ink outlet groove 4 connected to the ink chamber 3 is provided on the ink chamber body 8, an ink outlet seat 18 is fixedly installed on the ink chamber body 8, and an ink outlet channel 20 connected to the ink outlet groove 4 is provided on the ink outlet seat 18, and an adjusting member 19 is movably provided in the ink outlet channel 20, and the adjusting member 19 can adjust the opening size of the ink discharge end at the bottom of the ink outlet channel 20.

[0019] Furthermore, the apparatus further includes a U-shaped scraper pressing plate 11. The inner side of one end of the scraper pressing plate 11 presses the upper and lower scrapers against the ink chamber body 8. A snap-fitting protrusion 12 is provided on the side of the scraper pressing plate 11 corresponding to the scrapers. The ink chamber body 8 is provided with a slot 13 for the snap-fitting protrusion 12 to engage. The inner side of the other end of the scraper pressing plate 11 has a first arcuate groove 16. The ink chamber body 8 is provided with a second arcuate groove 14 corresponding to the first arcuate groove 16. A locking tube 15 with an elliptical cross-section is rotatably provided between the first and second arcuate grooves. By adopting the above-mentioned structure, the locking protrusion 12 and the slot 13 cooperate to achieve the positioning and snap-fitting of one end of the scraper pressing plate. Then, by controlling the rotation of the locking tube 15, the locking tube 15 can be pressed against the first and second arcuate grooves 16, achieving the squeeze-locking positioning of the other end of the scraper pressing plate 11, thereby conveniently achieving the positioning and disassembly of the island pressing plate.

[0020] Furthermore, a threaded portion 17 is provided on the adjusting member 19, and the threaded portion 17 is screwed onto the ink outlet seat 18. The ink outlet seat 18 is provided with an ink outlet joint 21 at the bottom of the ink outlet channel 20. The adjusting member 19 can be inserted into the ink outlet joint 21 to partially block it. By adopting this structure, it is only necessary to control the rotation of the threaded portion 17 to drive the adjusting member 19 to move in the ink outlet channel 20, thereby adjusting the blocking amount of the ink outlet joint 21 and adjusting the pressure of the ink in the entire ink chamber.

[0021] Furthermore, a connecting block 29 is provided on the ink chamber main body 8, and a first adjusting pin 25 and a second adjusting pin 27 are passed through the upper and lower parts of the connecting block 29. One end of the first adjusting pin 25 is arranged in the upper slide groove 24 of the side mounting frame 9, and one end of the second adjusting pin 27 is arranged in the lower slide groove 26 of the side mounting frame 9. The side mounting frame 9 is threaded with a first clamping screw 23 that can press the top of the first adjusting pin 25, and a second clamping screw 28 that can press the bottom of the second adjusting pin 27. By adopting this structure, the second clamping screw 28 can be controlled to rotate to lift the second adjusting pin 27 to the required height, thereby realizing the height adjustment of the ink chamber main body 8, and then the first clamping screw 23 can be controlled to rotate to clamp the top of the first adjusting pin 25, so as to avoid the ink chamber main body 8 from moving up and down during operation, thereby ensuring its stability during operation.

[0022] Furthermore, an ink collecting fountain 1 is provided below the ink chamber body 8, and an outlet 2 is provided at the bottom of the ink collecting fountain 1, which can collect the ink flowing out of the ink chamber body 8 and the ink outlet seat 18 for subsequent recycling.

[0023] The working principle of the present invention is as follows: the two ends of the anilox roller are respectively attached to the sealing block 7, and the upper and lower scraper leaves are attached to the outer wall of the anilox roller. The ink enters the ink chamber 3 through the ink inlet hole 22 and inks the outer wall of the anilox roller. As the anilox roller rotates, the scraper will scrape off the excess ink on the anilox roller. At the same time, the ink will enter the ink outlet seat 18 through the ink outlet groove 4 and flow out through the ink outlet joint 21. In addition, when it is necessary to adjust the ink pressure in the ink chamber to ensure the inking quality of the anilox roller, the adjustment member 19 can be controlled to move, the amount of blocking at the ink outlet joint 21 can be changed, and the size of the ink outlet can be changed to achieve the adjustment of the ink pressure inside the ink chamber 3.

[0024] This structure of the present invention achieves oil pressure regulation of the entire ink chamber flow by adding an ink outlet seat connected to the ink chamber and arranging an adjustment part in the ink outlet seat to adjust the opening size of the ink outlet end, thereby meeting different inking requirements and effectively improving its flexibility of use and inking quality.
