Description

The automatic powder spraying device

The utility model relates to and the supporting dusting device of middle and high fast sheet-fed offset press.

Along with the raising of homemade sheet-fed offset press printed sheet speed, the automatic powder spraying device has more and more caused the concern and the attention of respectively printing machine manufactory and printing house as the performance quality and the automaticity that guarantee a kind of auxiliary body that print quality is intact.General when the printed sheet speed of offset press reaches more than 5000/hour, after piling up, printing tends to produce anti-seal of picture and text and the difficult branch phenomenon of paper adhesion because of printing ink has little time drying.Therefore, be to prevent the paper adhesion and keep good picture and text effect, just must be in time to surface sprinkling one deck of each Zhang Yinpin as thin as a wafer and uniform special-purpose dust.Simultaneously for satisfying the broad applicability of offset press to different paper quality, printing breadth, print speed printing speed, the automatic powder spraying device just must have reliable powder outlet quantity adjustability, to adapt to the needs of various printings, because for each Zhang Yinpin, the dust of surface sprinkling has lacked and has not then played separating effect, but many color and lusters that both influence picture and text also can influence the last light effect of printing simultaneously.One of defective of homemade existing dusting device is: dusting does not have the apparatus for automatically replenishing structure, after the powder in the storage powder jar has sprayed, will stop offset press and add powder, and automaticity is low, has a strong impact on print production efficient and uses class; Two of defective is that the amount of dusting adjustability is relatively poor, often is difficult to satisfy the requirement of all kinds of offset presses.

The purpose of this utility model provides in the defective that overcomes prior art all that a kind of to have the automatic powder spraying device that adds the powder jar that automatically replenishes that dusts be first purpose; Provide simultaneously a kind of amount of dusting adjustability preferably the automatic powder spraying device of dust nozzle be second purpose.

The purpose of this utility model realizes by following technical proposal: this automatic powder spraying device comprises control damper, the generator that dusts, the dust nozzle that is equally spaced, be fastenedly connected into the series connection pattern with the sealing of siphunculus plug-in type between adjacent, it is characterized in that described dusting device also the eccentric position of the generator that dusts be provided with dust replenish automatically add the powder jar, this adds the powder jar and comprises cover and tank body, the below that ball valve is located at tank body is connected with siphunculus, and the extruding head with multiple flour opening specification is connected with siphunculus is detachable.

Described dust nozzle comprises the dust nozzle body with internal channel, dust nozzle body vertical axis direction is provided with convex platform and lower convex platform, be provided with the powder outlet quantity control valve that the bottom that is tightly connected is semi-circular structure in the convex platform, lower convex platform is provided with the extruding head that is spirally connected with it, piece together tight by piecing together cap, the extruding head circular surfaces is provided with a plurality of flour openings in 120 ° of scopes, have window, rotating shield ring sleeve is contained in outside the extruding head.

What this automatics owing to be provided with of dusting can realize automatic supply adds powder jar and the adjustable dust nozzle of the amount of dusting; make in adding the powder process offset press need not to shut down; can improve print production efficient and use class; the performance that the amount of dusting the is adjustable requirement of all kinds of offset presses that be content with very little to different paper quality, printing breadth, print speed printing speed; can guarantee that printing picture and text color and luster is good, can guarantee that again the printing glazing is effective.
