The utility model comprises an inking roller 3, blades 4, a press plate 6, a cutter frame 7, a bracket 10, a rotating shaft 11, an air cylinder 12, a sealing piece 2 and screws. The device is characterized in that: blade mounting planes of the cutter frame 7 are two planes 13 which are at a certain included angle of alpha to each other and are perpendicular to a section; the bottom of the cutter frame is provided with a positioning surface 14 perpendicular to the section; two ink scraping blades 4 are respectively placed on two blade mounting planes 13, and the bottoms of the ink scraping blades cling to the positioning surface 14; the bracket 10 is fixed on the rotating shaft 11; a screw hole and a long hole are arranged in two mutually perpendicular directions so as to regulate the mutually parallel positions of the cutter frame 7 and the inking roller 3; the rotating shaft 11 and the air cylinder 12 can lead the cutter frame 7 and the blades 4 to be in the working states of changing blades and scraping ink. The device has precise positioning function, can realize precise blade mounting and fast blade changing, improves the ink transfer precision of the inking roller, reduces the wear degree of the blades, and prolongs the life span of the blades.

Description

Sealed type is scraped device for ink

Technical field

The utility model relates to a kind of sealed type that is used for flexographic printing equipment control reticulate pattern inking roller ink transfer amount and scrapes device for ink.

Background technology

Traditional sealed type is scraped device for ink by the position of mobile doctor blade on knife rest, realizes adjusting position, pressure and the control ink transfer amount of blade and reticulate pattern inking roller, and the human factor of this operation is many, adjusts the dress cutter and often can not reach optimum efficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of accurate positioning function that has, and both can realize accurately adorning cutter, can realize rapid changing knife again, can improve reticulate pattern inking roller ink transfer precision, and the sealed type that reduced blade abrasion again, prolongs blade life is scraped device for ink.

The technical solution of the utility model comprises the reticulate pattern inking roller, blade, knife rest, pressing plate, support, rotating shaft, cylinder, seal and screw, the dress knife face that it is characterized in that knife rest is two and is mutually the α of certain angle and the plane of cross section perpendicular, locating surface with cross section perpendicular is arranged at its bottom, two blades are not placed on two dress cutter planes, locating surface is close in its bottom, the knife edge of two blades is in the position that is parallel to each other, knife rest is fixed on the support, seal is equipped with at the two ends of knife rest, and the screw for rack-mount usefulness is arranged at back and bottom, and angle α is 100 °～180 °; Support is fixed in the rotating shaft, support has the screw and the elongated hole of the position that is parallel to each other that supplies adjusting knife rest and reticulate pattern ink roller in two orthogonal directions, described cylinder is connected with rotating shaft, and described rotating shaft and cylinder rotate and make knife rest and blade be in tool changing or wiping operating position.That is to say, support rotates by rotating shaft, cylinder, forward the horizontal level changeable blade to, forward upright position (operating position) to and can form sealed type wiping chamber, China ink is by pump and pass in and out black pipe and enter in the sealed type wiping chamber and be embodied as reticulate pattern inking roller cyclic ink supply, accurately controls the target of its ink transfer amount.This shows that this device has accurate positioning function, both can realize accurately adorning cutter, can realize rapid changing knife again, it can not only improve the accurate ink transfer of reticulate pattern inking roller, and has reduced the degree of wear, the realization good printing of blade.

Description of drawings

The cross-sectional view that Fig. 1 scrapes device for ink for sealed type, wherein, the 1-ink, the 2-seal, 3-reticulate pattern inking roller, the 4-doctor blade, the 5-screw, the 6-pressing plate, the 7-knife rest, 8-presses closer screw, 9-stretching screw, 10-support, 11-rotating shaft, 12-cylinder.

Fig. 2 is knife rest of the present utility model, supporting structure enlarged diagram, wherein, and 13-dress cutter plane, 14-locating surface, 15-elongated hole.

The specific embodiment

Referring to Fig. 1, this device mainly is made up of blade 4, knife rest 7, support 10, rotating shaft 11, cylinder 12, seal 2 and screw 5,8,9 and pressing plate 6 etc.

Blade 4 is fixed on the knife rest 7 by pressing plate 6, screw 5 among Fig. 1, seal 2 is fixed on the two ends of knife rest 7, knife rest 7 by press closer screw 8, stretching screw 9 is fixed on the support 10, support 10 rotates by rotating shaft 11, cylinder 12, forward horizontal level changeable blade 4 to, forward upright position (operating position) to and can form sealed type wiping chamber, ink 1 is by pump and pass in and out black pipeline and enter in the sealed type wiping chamber and be embodied as reticulate pattern inking roller 3 cyclic ink supplies, accurately control the target of its ink transfer amount.

Referring to Fig. 2, the dress knife face of knife rest 7 is two planes 13 that are mutually certain angle α and cross section perpendicular, locating surface 14 with cross section perpendicular is arranged at its bottom, when two doctors 4 are placed on respectively on two dress knife faces 13, when locating surface 14 was close in its bottom, then the knife edge of two doctors 4 was in the position that is parallel to each other.Seal 2 is equipped with at the two ends of knife rest 7, and all there is screw its back and bottom for the usefulness that is installed on the support 10.

Described support 10 is fixed in the rotating shaft 11, in two orthogonal directions screw and elongated hole 15 are arranged, for regulating knife rest 4 and reticulate pattern inking roller 3 relative positions, finish in case adjust, then the parallel relation of the cutting edge of a knife or a sword mouth of blade 4 and reticulate pattern inking roller 3 is promptly definite, so each from now on tool changing only needs locating surface 14 is close in the bottom of blade 4, presses pressing plate 6, tightens screw 5 and gets final product.

The technical characterictic one of this device is: the dress knife face of knife rest 7 is two planes 13 that are mutually certain angle α and cross section perpendicular, locating surface 14 with cross section perpendicular is arranged at its bottom, when two doctors 4 are placed on respectively on two dress knife faces 13, locating surface 14 is close in its bottom, then the knife edge of two doctors 4 then is in the location status that is parallel to each other automatically, and its angle α is 130 °.

The technical characterictic two of this device is: support 10 is fixed in the rotating shaft 11, screw and elongated hole 15 are arranged for regulating the be parallel to each other position of knife rest 7 with reticulate pattern inking roller 3 in two orthogonal directions, rotating shaft 11 and cylinder 12 can make knife rest 7 and blade 4 be in tool changing or wiping duty.This device has accurate positioning function, both can realize accurately adorning cutter, can realize rapid changing knife again, and it can not only improve reticulate pattern inking roller ink transfer precision, and has reduced the degree of wear of blade.
