Description
Technical field
The invention belongs to a kind of ad hoc approach printed by ink, specifically disclose a kind of printing of removal solidification ink
Method.
Background technology
Printing technology is closely bound up with daily life, various books used in everyday, newspapers and periodicals and various
There is the word or pattern printed by printing technology on textile.
Existing printing technology is typically that the ink in ink tank is coated on printing roller by fountain roller, is then passed through
Ink is imprinted on the printed object such as paper by printing roller, to printing roller by ink after printing roller has been coated ink
It is imprinted on paper and goes forward, need to carry out the process that the ink by printing roller surface smoothes out together, to avoid printing roller table
The ink of face attachment is unevenly distributed and causes printing effect bad.
By the way that the ink on printing roller is smoothed out this process, although so that the ink distribution on printing roller surface is equal
It is even, but when printing roller is contacted with paper, by ink impression on paper, paper can not fully absorb all printing roller
Ink, therefore remain a small amount of ink on printing cylinder, since a large amount of solvents have been absorbed by paper in these inks, residual
Coloured particle be quickly set in printing roller surface, form the solid for being attached to printing roller surface, these solids cause to print
Brush roller surface cannot keep smooth, and existing floating technique can not eliminate solidification ink so that printing quality reduces.
Invention content
The invention discloses a kind of printing processes of removal solidification ink, it is therefore intended that print can not be removed by solving the prior art
The problem of solidification ink adhered on brush roller.
The present invention base case be：A kind of printing process of removal solidification ink, includes the following steps：
Step 1：Prepare a scraper plate and a nozzle, prepares following ink cleaning agent dispensing, ethylene glycol ethyl ether 40~50
Part, 10~15 parts of dipropylene glycol methyl ether, 5~10 parts of diethylene glycol ether, 30~40 parts of water；
Step 2：The ink cleaning agent dispensing prepared in step 1 is mixed to get ink cleaning agent；
Step 3：Before scraper plate is fixed on fountain roller so that printing roller first contacts with scraper plate and carries out inking again；
Step 4：Start printing roller, then starts nozzle and spray ink cleaning agent to printing roller surface so that printing
Roller first sprays upper ink cleaning agent before being contacted with scraper plate by nozzle.
The technical principle and advantageous effect of the present invention is：
1. being used as solvent, dipropylene glycol methyl ether by adding ethylene glycol ethyl ether in ink cleaning agent in step 1 of the present invention
With diethylene glycol ether as secondary solvent so that ink under the infiltration of ink cleaning agent be dissolved with ink cleaning agent in,
To avoid the ink of solidification from being difficult to root out with printing roller surface adhesion-tight.
Before 2. scraper plate is fixed on fountain roller in step 3 of the present invention so that printing roller is by the upper ink once coated
After being printed onto on paper, first contacted with scraper plate so that scraper plate scrapes the residual ink on printing roller surface, then applies again again
New ink is covered, when to ensure to coat new ink, printing roller surface noresidue ink, and then ensure new ink coating
When keep even uniform.
3. by spraying ink cleaning to printing roller surface before printing roller is contacted with scraper plate in step 4 of the present invention
Agent so that the ink of the solidification of printing roller surface residual is first dissolved as liquid by ink cleaning agent, to avoid the ink of solidification
The problem of adhesion-tight between water and printing roller, scraper plate is difficult to scrape.
Further, pressure is 0.3~0.4Mpa when the nozzle sprays ink cleaning agent.Pass through above-mentioned design so that spray
When head sprays ink cleaning agent, ink cleaning agent has certain initial velocity, so as to smoothly be sprayed onto on printing roller surface.
Further, pretightning force is 0.1~0.3 times of scraper plate its own gravity between the scraper plate and printing roller.By upper
Design is stated so that being pushed against between scraper plate and printing roller, so that scraper plate scraping off residual ink is better.
Further, the flow of the nozzle is 0.4~0.6m^3/h.Pass through above-mentioned design so that the ink that nozzle sprays
The amount of cleaning agent excessively will not cause to waste.
Further, the ink cleaning agent dispensing is stirred at 50 DEG C.Pass through above-mentioned design so that ink cleaning agent
When being stirred, mixing velocity is faster.

It is flowed into woven hose 18, when piston plate is towards close to the movement of the direction of woven hose 18, in the effect of check valve and pressure difference
The lower liquid by woven hose 18 is towards pushing in spray chamber so that ink cleaning agent enters in spray chamber, finally from spray hole 20
It sprays to printing roller 1, ink cleaning agent infiltrates ink remaining on printing cylinder after being sprayed on printing roller 1 so that
Remaining ink is dissolved.
With being rotated further for printing roller 1, ink cleaning agent and dissolved ink are scraped and rested on by wedge surfaces
In the space that baffle 3, wedge surface and printing roller 1 are surrounded, with the continuous rotation of printing roller 1, baffle 3, wedge surface and printing
The liquid retained in the space that roller 1 is surrounded is continuously increased, when in the space that baffle 3, wedge surface and printing roller 1 are surrounded
When the liquid levels retained are higher than the liquid level in liquid reserve tank 14, the pressure suffered by one side of the cover board 21 close to return port 15 is more than
One side of the cover board 21 far from return port 15 opens return port 15 to drive cover board 21 to overcome the pulling force of tension spring so that gear
Ink cleaning agent in the space that plate 3, wedge surface and printing roller 1 are surrounded flows into liquid reserve tank 14, avoid baffle 3, wedge surface and
The liquid stored in the space that printing roller 1 is surrounded is excessive, while also achieving recycling for ink cleaning agent.
With the rotation of printing roller 1, when printing roller 1 is after wedge surface, contacted with cleaning roller 5, on 5 surface of cleaning roller
Spongy layer 6 under the action of, a small amount of ink cleaning agent of 1 surface residual of printing roller is absorbed cleanly.
When the ink dissolved in the ink cleaning agent in liquid reserve tank 14 reaches saturation state, the switch of inlet 19 is opened
Valve releases the ink cleaning agent in liquid reserve tank 14, is then passed through the replacement that new ink cleaning agent completes ink cleaning agent.
Above-described is only the embodiment of the present invention, and the common sense such as well known concrete structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these should also be considered as protection scope of the present invention, these all do not interfere with what the present invention was implemented
Effect and patent practicability.
