The principle of this programme is:During practical application, slipping ring has certain wall thickness, and the inner of lever is located at the outside of slipping ring
Between wall and ink tube, so that during lever rotation, the inner can be touched with slipping ring.Print cartridge is under the promotion of cylinder in black cylinder
Glide, the engaging tooth on print cartridge follows print cartridge to move and slided in the chute on black cylinder, so as to promote the tooth engaged with print cartridge
Wheel is rotated, and the rotation of gear will drive the first steel cable to be wound in the winding slot of gear, so that the first steel cable is received short, thus,
The outer end for the lever being connected with the first steel cable is pulled to rise.Under leverage, the inner sinking of lever, the inner is slided along camber line
It is dynamic, during slipping ring in touching ink tube, and promote slipping ring to glide, so as to the spray orifice of slipping ring situ be opened, print cartridge
In ink be ejected to by through hole in black cylinder.While the outer end of lever rises, pull on connected second steel cable and move up, by
In the other end of the second steel cable be to be connected through sponge strip with ball, therefore the second steel cable pull on ball by jet pipe enter branch
In pipe, thus, jet pipe is opened, the ink in black cylinder is ejected to by injector in jet pipe, and by being ejected in jet pipe under jet pipe
On side's plastic products to be processed, so as to realize brush mark.Jet pipe defines scope out of ink, so as to avoid ink being sprayed onto plastics system
Other positions of product, cause the pollution of surface of plastic products.
When ball is moved in branch pipe, branch pipe is blocked all the time, so as to which sponge strip and jet pipe are isolated, therefore sponge
Bar will not directly be drawn into jet pipe ink and be wetted, because the inside of sponge-like material has loose structure, easily hair
Raw capillarity, in this role, the spongy layer that only a small amount of ink is wrapped up on the outside of ball are drawn and are transferred in sponge strip,
It thus can preferably realize that sponge strip is isolated with black.And when ink-jet, the second steel cable pulls ball movement, ball will extrude sea
Continuous bar, reduces sponge strip, and under such a state, sponge strip is difficult to blotting, so that the ink amount needed for ensureing brush mark.
After the brush mark of plastic products is completed, cylinder pulls print cartridge to move up return, and engaging tooth follows print cartridge to move up and promote
Gear is rotated backward so that the first steel cable is lengthened, and the outer end of lever loses the pulling force of the first steel cable, under leverage, outside

The ink stayed, sponge strip also draws the ink remained in branch pipe, is achieved in, to residual black timely cleaning in jet pipe and branch pipe, effectively keeping away
Exempt from the phenomenon that residual ink spills pollution plastic products, lift the brush mark quality of plastic products.Also, under capillary action, sponge
Ink in layer and sponge strip will be moved from other drying section displacements of trend sponge strip or spongy layer, so as to ensure spongy layer or sponge
The local ink absorption of bar, it is ensured that residual ink can thoroughly be absorbed.
When entering next brush beacon course sequence, steel ball will again be pulled by the second steel cable and squeezed in branch in-pipe, and again
Sponge strip is pressed, so that the residual ink saved in sponge strip is extruded, and is expelled to by venting pipe outside device, and carries out secondary returning
Receive.After the residual ink in sponge strip is extruded, compared to the spongy layer not being extruded, the aridity of sponge strip is higher, therefore sponge
Residual ink in layer will be shifted automatically again under capillary action, and be handled in sponge strip, thus, constantly be realized residual
The cleaning of ink is reclaimed with discharge.
, therefore, can be as needed in black cylinder during practical application because Qing Mo mechanisms are detachably connected on black cylinder bottom portion
