Abstract
The invention discloses a scraping blade for a printing machine, relates to a printing machine and provides the scraping blade for the printing machine with simple structure, difficult deformation when working, low cost and long service life. The scraping blade for the printing machine is provided with a squeegee adhesive tape and a fixing piece, wherein the squeegee adhesive tape is an elastic plastic adhesive tape; the fixing piece is provided with a front plate and a rear plate; the front plate and the rear plate are clamped on front and rear surfaces of the squeegee adhesive tape in a thickness direction respectively; the front plate and the rear plate are adhered to the squeegee adhesive tape and connected with each other; and a top surface of the squeegee adhesive tape is provided with a guide inclined plane and a retained plane.
Description
Technical field
The present invention relates to printing machine, especially relate to a kind of scraping blade for printing machine.
Background technology
Printing machine (like offset press) doctor requires when work, to keep good consistency and elasticity, keep the slanted angle that contacts between doctor and the celluloid ink roller, could guarantee the accuracy of wiping, guarantees printing quality.But the adhesive tape that doctor is commonly used at present all is the sulfuration adhesive tape usually, and production technology is complicated, and cost is high; And receive mould restriction, the adhesive tape case hardness is acquired a certain degree (about 75 degree), during use because of the too soft easy deformation of generating heat; Even be involved in the rubber roll of printing machine; Cause the rubber roll scratch, can't guarantee the wiping quality at all, doctor is short service life.In addition, it generally all is bonding being used between fixture and the adhesive tape of clamping adhesive tape, during use; Can't guarantee the doctor integral intensity, cause the wiping inaccuracy unclean, influence printing quality; Also need clean ink roller, cause a large amount of wastes of resource and environmental pollution with a large amount of cleaning agents and water.
Publication number is that the application for a patent for invention of CN1561289 discloses a kind of scraping blade for printing machine.This doctor has an overall structure, and comprises a working end and an installation end.This working end is preferably much thick than installation end, thereby in the working end more material is provided.When doctor engaged with the scraping roller of printing machine, doctor received abrasive action, and the additional materials that provides has improved the service life of doctor.Keep enough pliabilities and deflection characteristic in order to ensure doctor, other part of doctor or the thickness of installation end reduce greatly.Doctor can be processed with further raising pliability by spring steel.
Notification number is the doctor fixation device that the utility model patent of CN201092134 discloses a kind of high speed intaglio press; Comprise train wheel bridge, lower plate and scraper base plate; Insert and put middle clamp plate in the wedge surface that the front end lower inclined plane of train wheel bridge and the plane of lower plate form; The rear end upper surface of middle clamp plate is the inclined-plane, between the front end lower surface of middle clamp plate and the lower plate doctor blade is installed, and middle clamp plate is connected with train wheel bridge through fishbolt.This utility model can directly be changed doctor blade on printing machine, it is convenient to change, and the used time shortens; Whole rigidity is strengthened, and has reduced the vibration of scraper, has improved the quality of printed matter, has reduced percent defective, has improved efficient.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, work is not yielding, cost is low, the scraping blade for printing machine of long service life.
The present invention is provided with wiping adhesive tape and fixture; The wiping adhesive tape is the Elastic plastic-rubber adhesive tape; Fixture is provided with header board and back plate, and header board is clamped in respectively on two surfaces, front and back of wiping adhesive tape thickness direction with the back plate, and header board all bonds with back plate and wiping adhesive tape; And header board is connected between the plate with the back, and the end face of wiping adhesive tape is provided with the water conservancy diversion inclined-plane and is detained the plane.
Said header board can be front spring, and back plate can be the back steel plate; Said header board is connected between the plate with the back, preferably header board with afterwards pass through rivet between the plate.
Preferred 5～the 11mm of the thickness of said wiping adhesive tape, the oblique angle on said water conservancy diversion inclined-plane is preferably 50 °～52 °, and the width on said delay plane is preferably 1.5～1.8mm.
Said wiping adhesive tape is preferably polymer elasticity plastic cement adhesive tape for the Elastic plastic-rubber adhesive tape, like polyurethane Elastic plastic-rubber adhesive tape.
Compare with prior art, the present invention has following outstanding advantage:
Because wiping adhesive tape of the present invention adopts the Elastic plastic-rubber adhesive tape; Therefore can be as required the elastic plastic material that satisfies performance requirement (like hardness, tensile strength, coefficient of elasticity, heat-resisting, wear-resisting etc.) being carried out moulding makes and gets final product; Production technology is very simple, and cost significantly reduces.Owing to through rivet, therefore can guarantee doctor glacing flatness and rigidity between front spring and the back steel plate, prevent work distortion (if distortion; Will produce oneself vibration, and the oneself vibrates to such an extent that frequency can increase with the rotating speed of inking roller and raises), good stability when making work; The wiping precision is high; Obviously improve printing quality, economize on resources, avoid waste.In addition, because the end face of wiping adhesive tape not only is provided with the water conservancy diversion inclined-plane, also is provided with and is detained the plane, when therefore working; Wiping adhesive tape contact-making surface contacts with ink roller, is detained between plane and the ink roller circumference cambered surface to form V font groove, cleans in the ink roller process; This V font groove can be detained some ink cleaning liquids all the time, like this, just ink cleaning liquid is all flowed away quickly from the water conservancy diversion inclined-plane; Thereby the wiping adhesive tape is played better cooling effect, make the wiping adhesive tape more not yielding, improve service life; Can significantly save ink cleaning liquid, (through contrast test, ink cleaning liquid can reduce by 60% above consumption) reduces cost.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Referring to Fig. 1, the present invention is provided with wiping adhesive tape 1 and fixture, and wiping adhesive tape 1 is Elastic plastic-rubber adhesive tape (a polyurethane Elastic plastic-rubber adhesive tape), and fixture is made up of front spring 21 and back steel plate 22.Front spring 21 is clamped in respectively on two surfaces, front and back of wiping adhesive tape 1 thickness direction with back steel plate 22; Front spring 21 all bonds with wiping adhesive tape 1 with back steel plate 22; And through rivet 3 riveted joints, the end face of wiping adhesive tape 1 is provided with water conservancy diversion inclined-plane 12 and is detained plane 11 between front spring 21 and the back steel plate 22.
The thickness of wiping adhesive tape is preferably 5～11mm, and the oblique angle on water conservancy diversion inclined-plane is preferably 50 °～52 °, and the width that is detained the plane is preferably 1.5～1.8mm.Length is joined work according to concrete type.
