Abstract
The invention discloses a closed scraper device used for a gravure printing machine. The closed scraper device used for the gravure printing machine comprises a stand and a closed scraper cavity arranged on the stand, an adjustable scraper is arranged at the concave surface of the upper part of the closed scraper cavity, a fixed scraper is arranged at the lower part of the closed scraper cavity, the adjustable scraper is capable of moving along the concave surface of the closed scraper cavity, and a head face sealing block is arranged at each of the joint between the adjustable scraper and a printing plate roller and the joint between the fixed scraper and the printing plate roller; the adjustable scraper, closed scraper cavity, fixed scraper, printing plate roller and head face sealing blocks jointly form a closed cavity in a surrounding mode. The closed scraper device used for the gravure printing machine solves the problems that an existing open type scraper device is low in printing quality and large in printing ink consumption due to solvent evaporation in printing ink storage.
Description
Technical field
The invention belongs to printing mechanism technical field, relate to a kind of closed doctor blade device for intaglio press.
Background technology
At present, the doctor blade device of intaglio press mostly is as Open architecture, and there is ink storage cannot seal, and solvent volatile quantity is large, to environment, operator's health is caused damage, simultaneously, because solvent volatilization causes ink viscosity to change, affect press quality, cause mass loss; Ink consumption is large, and to use, enterprise causes waste.
Summary of the invention
The object of this invention is to provide a kind of closed doctor blade device for intaglio press, solve the printing quality that existing open doctor blade device causes because solvent when ink stores volatilizees not high, the problem that ink consumption amount is large.
The technical solution adopted in the present invention is, a kind of closed doctor blade device for intaglio press, it is characterized in that, comprise frame and rack-mounted closed scraper cavity, the concave surface closing scraper cavity top is provided with adjusting scraper, close the bottom of scraper cavity and be provided with fixed doctor, adjusting scraper can move along the concave surface of closed scraper cavity, is provided with end face seal block in adjusting scraper and the junction of printing plate cylinder and the junction of fixed doctor and printing plate cylinder; Adjusting scraper, closed scraper cavity, fixed doctor, printing plate cylinder and end face seal block surround a closed cavity jointly.
Feature of the present invention is also,
In closed cavity, ink is housed.
Adjusting scraper all contacts with printing plate cylinder with the knife edge part of fixed doctor.
Frame is provided with scraper wobble drive machine and clutch air cylinder.
Adjusting scraper rear is connected with the regulating handle of the position for regulating adjusting scraper.
The rear closing scraper cavity is respectively arranged with ink entrance and ink outlet port, and ink entrance is all communicated with closed cavity with ink outlet port.
Frame lower is provided with trimming handle, and trimming handle is connected with frame.
The invention has the beneficial effects as follows, closed scraper ink storage space of the present invention is little, saves ink, and ink storage chamber is closed, and do not have solvent volatilization, contaminated environment, ink viscosity is stablized, and press quality can be guaranteed.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of closed doctor blade device for intaglio press of the present invention, as shown in Figure 1, the closed scraper cavity 4 comprising frame 13 and be arranged in frame 13, the concave surface closing scraper cavity 4 top is provided with adjusting scraper 3, the bottom closing scraper cavity 4 is provided with fixed doctor 12, adjusting scraper 3 can move along the concave surface of closed scraper cavity 4, is provided with end face seal block 2 in adjusting scraper 3 and the junction of printing plate cylinder 1 and the junction of fixed doctor and printing plate cylinder 1;
Adjusting scraper 3, closed scraper cavity 4, fixed doctor 12, printing plate cylinder 1 and end face seal block 2 surround a closed cavity 11 jointly, in closed cavity 6, ink are housed; Adjusting scraper 3 all contacts with printing plate cylinder with the knife edge part of fixed doctor 12;
Frame 13 is provided with scraper wobble drive machine 9 and clutch air cylinder 10.
As shown in Figure 2, adjusting scraper 3 rear is connected with regulating handle 5, for regulating the position of adjusting scraper, makes it contact with the surface of printing plate cylinder better;
The rear closing scraper cavity 4 is respectively arranged with ink entrance 7 and ink outlet port 6, ink entrance 7 is all communicated with closed cavity 11 with ink outlet port 6, the ink of printing enters closed cavity 11 from ink entrance 7, when the liquid level of ink arrives the height of ink outlet port 6, will overflow from ink outlet port 6, the quantity of ink this ensures that thered in closed cavity remains at a constant level, steady quality during such guarantee printing.
Frame lower is provided with trimming handle 8, and trimming handle 8 is connected with frame 13, for regulating the front and back position of frame 13, keeps rational distance between the whole closed doctor blade device made and printing plate cylinder, and printing is carried out smoothly.
Printing-ink, in closed cavity 11, can reduce the volatilization of solvent in ink; Adjusting scraper can according to printing plate cylinder diameter adjustment scraper squeegee angle; Clutch air cylinder 10 realization is left and combined pressure with printing plate cylinder; Trimming handle 8 can realize the minor adjustments of scraper pressure; Scraper swing mechanism drives scraper trace to swing, and reduces scraper the gathering of particle in the wear extent and ink of same position, extends scraper service life, ensures print quality.
Operationally, clutch air cylinder 10 combined pressure, drives scraper entirety to contact with printing plate cylinder 1 in the present invention, form the cavity closed, ink enters the areas of printing plate cylinder 1, rotates with roller, scrape off excess ink by adjusting scraper 3, realize the function that roller transferred to by gravure ink.If printing plate cylinder 1 diameter changes, adjustment adjusting scraper regulating handle 5 arrives suitable angle, to meet desirable wiping effect.If the change of printing plate cylinder 1 diameter is very little, trimming handle 8 can be regulated, adapt to roller change, ensure that scraper pressure meets the demands.Scraper wobble drive machine 9 drives scraper trace to swing, and reduces scraper the gathering of particle in the wear extent and ink of same position, extends scraper service life, ensures print quality.
The present invention has following beneficial effect:
1. adopt and close scraper, printing-ink is closed in scraper cavity, saves ink, reduces solvent volatilization, improves operating environment, reduces ink viscosity change, improves press quality;
2. adjusting scraper carries out squeegee angle adjustment, the wiping effect of realizing ideal according to the change of printing plate cylinder diameter;
3. clutch can realize the clutch action of scraper, and ensures that scraper pressure is suitable in roller diameter excursion;
4. scraper micro-adjusting mechanism can regulate scraper to move forward and backward by trace, the wiping effect of realizing ideal;
5. scraper swing mechanism drives scraper trace to swing, and reduces scraper the gathering of particle in the wear extent and ink of same position, extends scraper service life, ensures print quality.
