Description

A kind of prosthetic device of printing machine sdueegee

Technical field

The invention belongs to intaglio printing supporting technology field, relate to a kind of prosthetic device of intaglio press sdueegee.

Background technology

Sdueegee is the precision component of indispensable a, rapid wear for intaglio press, its function is scraped totally by the excess ink on the print roller surface of full for leaching ink, only leaving ink in reservation dimpled grain ditch is guided on stock by pressure again, if the excess ink on print roller surface is scraped unclean, institute's impression literary composition is just unintelligible, so very high to the flatness requirement of sdueegee, the sharp cube sheet of corner angle made by the general lower macromolecular material (such as plastic plate or rubber slab) of hardness ratio print roller that adopts.But, not only the flatness of market purchase commodity sdueegee does not reach required precision and cannot directly use, and sdueegee and print roller exist Relative friction and move and make wearing and tearing frequency remain high in printing process, so take repairing method to be the common recognition of intaglio printing industry.

In the past, people taked two kinds of ways to repair sdueegees usually: a kind of way being hand knife and cutting, and not only poor flatness, inefficiency, damage rate are high, and the personnel being engaged in reparation operation are easily injured; Another kind is the way with planer, although the precision of repairing is feasible, starts shooting frequently, shuts down and cause inefficiency, just as beating mosquito with guided missile.

Therefore, invention makes a kind of compact structure, operates the enough high sdueegee prosthetic devices of easy, precision and just have very necessary.

Summary of the invention

The object of the present invention is to provide a kind of prosthetic device of printing machine sdueegee, under the prerequisite ensureing flatness, also will reach compact structure, operate requirement that is simple and easy, safe and reliable, that raise the efficiency and reduce costs.

For reaching above-mentioned purpose, the prosthetic device of printing machine sdueegee provided by the present invention, comprise slide mechanism, cutting mechanism, guiding mechanism and supporting mechanism, the guide rail coupling being positioned at groove bottom slide mechanism and guiding mechanism has sliding function, below the guide rail that cutting mechanism is bolted on guiding mechanism and the notch making blade pass track exposes the knife edge, guiding mechanism is arranged on the end face of supporting mechanism, between track and support, have flying height.

Preferentially, described slide mechanism comprises: described hinged lock mandrel, slide block, screwed hole on slide block, sdueegee slot, set lever and locking square, set lever by screw thread or welding respectively with slide block with lock square and be linked to be two independent integers, the screw thread that hinged lock mandrel goes directly on slide block through locking square becomes hinge arrangement, sdueegee to be repaired is inserted in the sdueegee slot of slide block, hold set lever exert pressure downwards drive locking square rotate the corner angle of locking square are locked sdueegee to be repaired, the groove of the mutual coupling with track is had in the bottom of slide block.

Preferably, described cutting mechanism comprises chock, blade and clamping screw below installation inclined male window place in orbit, do not become vertical with the angle of track in the wide mouth of blade plug inclined male window in orbit, the splitting in the slot of shape tongue piece plug inclined male window in orbit and rely on tapped blind hole on clamping screw and track and blade is fixed of chock, the end face of the wide mouth of inclined male window only exposes the knife edge part of blade in orbit.

Preferably, described guiding mechanism comprises track and countersunk head through hole and bolt, track is dull and stereotyped or prism, excavate an inclined male notch and one or two tapped blind hole at the middle part of track and be used for fixing chock in cutting mechanism and blade, track is by the countersunk head through hole on welding or four angles and be bolted to above supporting mechanism.

Preferably, described supporting mechanism comprises: be arranged on the support below the baffle plate at track two and track, the height of baffle plate is greater than the thickness of track, or the width of baffle plate is greater than the width of track, the scope of slidably reciprocating arranging baffle plate limit slippage mechanism is less than the length of track, and makes to keep flying height between track and support.

The Advantageous Effects of the prosthetic device of printing machine sdueegee of the present invention: operator only needs both hands to hold with a firm grip two set levers of slide mechanism, by both hands deadweight with the gravity pressure of slide mechanism in orbit, hand push slide mechanism slides and after accelerating a segment distance fast, sdueegee to be repaired in drive sdueegee slot is steadily quickly through the blade of blade, and the Edge divider that can arrive sdueegee repairs smooth, sharp effect.This woman bright prosthetic device compact structure, operate easy, precision enough high, security is high, efficiency is high, cost is low, operating cost is low, only need cut and once just can realize effective reparation.
