Embodiment approach 1

[0051] like figure 1 As shown, the doctor blade system of the printing machine includes a frame 1, a tension roller group and an anilox roller 12, and the tension roller group is composed of several tension rollers 11, and the tension roller group is used to tension the printing and dyeing products 17 on the On the mesh stick 12. A scraper mechanism is arranged on the frame 1, and the scraper mechanism is arranged on one side of the anilox roller.

[0052] like Figure 1 to Figure 9 As shown, the scraper mechanism includes a rack seat 2, a rack 21, a gear 22, a first rotating shaft 31, a first control box 3, a first worm wheel 33, a first worm 32, a sleeve member 23, a knife holder shaft 4, a first Two manipulation boxes 5, the second worm gear 51, the second worm screw 52, ​​the knife rest seat 6 and the blade 61.

[0053] like Figure 1 to Figure 9 As shown, the rack 21 is slidably connected to the rack seat 2 . The sliding direction of the rack 21 on the rack seat 2 is...

Embodiment approach 2

[0065] The difference between Embodiment 2 and Embodiment 1 lies in the structure of the upper splint.

[0066] Definition, when used, the direction parallel to the anilox roller is the left and right direction; the terms "high" and "low" refer to the relative positional relationship in the working state.

[0067] Definition When in use, the end close to the anilox rod is the outer end, and the end away from the anilox rod is the inner end. When using this embodiment, it is preferred to adjust the blade to a state where the outer end is high and the inner end is low.

[0068] like Figure 10 to Figure 13 As shown, the outer end of the upper splint 7 is provided with a sump 75, and the left and right ends of the sump 75 are closed. A drain groove 76 is provided on the lower side of the upper splint 7 . The drain groove 76 is arranged in a manner that one end is higher and the other end is lower in the length direction. A plurality of diversion grooves 77 are arranged on the ...

Embodiment approach 3

[0072] like Figure 14 As shown, the difference between this embodiment and the first embodiment is that the first crossbar 15 and the second crossbar 16 are slidably connected between the first support 13 and the second support 14 . The first cross bar 15 and the second cross bar 16 can reciprocally slide along the length direction. The frame 1 is provided with a driving mechanism for driving the first crossbar 15 and the second crossbar 16 to reciprocate. By connecting the motor 18 on the frame 1, connecting a swing arm 8 on the rotating shaft of the motor 18, rotating a roller 81 at the end of the swing arm 8, and connecting a roller 81 at the end of the second cross bar 16 Guide block 9, a chute 91 is set on the guide block 9, the chute 91 is arranged in the up and down direction, and the roller 81 is arranged in the chute to form a driving mechanism for driving the reciprocating motion of the first crossbar and the second crossbar . The reciprocating movement of the sc...

Abstract

The invention provides a scraping knife system of a printing machine, and relates to the technical field of printing. The scraping knife system is used for solving the problem of uneven ink on an anilox roller in the prior art. The scraping knife system of the printing press includes a machine frame, a tensioning rod group and the anilox roller. The machine frame is provided with a scraping knifemechanism, and the scraping knife mechanism is arranged on one side of the anilox roller; the scraping knife mechanism includes a rack seat, a rack, a gear, a first rotating shaft, a first control box, a first worm wheel, a first worm, a sleeve piece, a knife rest shaft, a second control box, a second worm wheel, a second worm, a knife rest seat and a blade; the knife rest seat is connected to theknife rest shaft, a sliding block is slidably connected to the knife rest seat, a lead screw nut mechanism is arranged between the sliding block and the knife rest seat, and a knife rest is connectedto the sliding block; and the blade is arranged on the knife rest, and the scraping knife mechanism is used for scraping the anilox roller. The scraping knife system has the beneficial effect of ensuring that the ink on the anilox roller is uniform.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a doctor blade system of a printing machine. Background technique [0002] A printing press for printing work on surfaces such as films. The working principle of the printing machine is to convey the printed material through the winding and / or unwinding mechanism, and tension the conveyed material to the surface of the anilox roller through a series of tension rollers. The anilox roller is used to pick up the ink, and the printing work is carried out through the relative movement of the material and the anilox roller. [0003] The above printing work in the prior art has the problem that after the anilox roller dips the ink, the ink is distributed unevenly on the surface of the anilox roller, which reduces the printing quality. [0004] That is to say, there is a problem of uneven ink on the anilox roller when the printing machine in the prior art is working. Contents of the...
