Edge in the upper mounting plate bottom near lower installation board is provided with angle adjusting mechanism, this mechanism comprises groove, angle-regulating block and lock screw, angle-regulating block can be that central shaft is rotated and it deviates from the axis of two hinges with the lock screw, and promptly angle-regulating block and two hinges are not on the same straight line.
Tin-blocking plate comprises sliding shoe, is provided with the projection that is slidingly connected with lower installation board on sliding shoe.
Between upper mounting plate and lower installation board, also be provided with elastic force apparatus, so that the corresponding sides of angle-regulating block and lower installation board top remain the state of pushing against, this elastic force apparatus can comprise torsion spring or the spring between upper mounting plate and lower installation board that is installed on the hinge, simultaneously, from the utility model side, this spring or torsion spring and groove occupy the both sides of hinge respectively, and promptly groove is positioned at the front of doctor blade holder, and spring or torsion spring then are positioned at the back side of doctor blade holder.
Further set forth the technical solution of the utility model and architectural feature below particularly.
Hinge is fixed on the connecting block, and two contiguous blocks are protruding is born in the lower installation board top, and is left-right symmetry distributes on lower installation board.
Lower installation board is the strip that keeps flat, and its top is plane, and wideer than the bottom, is provided with a press strip in a side of its length direction, is folded with a wing between press strip and lower installation board, and wing is detachable fixedlying connected with lower installation board; Also be shaped on T-slot or the dovetail groove of always wearing the whole length of installing plate in that side relative with press strip.
Groove is located at the front of upper mounting plate, and the distance of upper mounting plate bottom is arrived less than its radius in its center; Lock screw passes the center that is tightened in groove behind the angle-regulating block.
Angle-regulating block is the thin piece of triangle or polygon, and aperture in set hole and lock screw are suitable on it, and the hole heart is all inequality to the distance at each edge, limit of angle-regulating block, and every limit all can contact with the top of lower installation board.
Projection on the sliding shoe is suitable for being inserted in the above the T-slot or dovetail groove of lower installation board, and tin-blocking plate can be free to slide along described groove by the guiding of projection; Also be provided with a set screw on tin-blocking plate, this set screw one end is embedded in the described groove, and can at an arbitrary position tin-blocking plate be locked on the lower installation board.
In summary it can be seen, the utility model compared to existing technology, its advantage is: 1, upper mounting plate is connected by hinge with lower installation board, and on upper mounting plate, the position that deviates from the hinge axis is provided with an angle adjusting mechanism, and the distance that lock screw is grabbed to rotating shaft in each edge, limit of the angle-regulating block of this mechanism has nothing in common with each other, keep in touch at each edge, limit and lower installation board top simultaneously, this just makes when the rotational angle regulating block, the distance at lock screw and lower installation board top can change, can know by the mathematics geometric knowledge, angle between upper mounting plate and the lower installation board also changes thereupon, and then causes the angle between wing and the upper mounting plate to change.Since upper mounting plate be fixed in printing machine on, so the angle between wing and the steel mesh promptly changes.
2, the utility model lower installation board is provided with T-slot or dovetail groove, and tin-blocking plate can be conditioned the optional position that screw is fixed on described groove.Simultaneously, be detachable fixedlying connected between wing and the lower installation board, thereby can change the wing of required length, and tin-blocking plate can be positioned at the both sides of wing all the time, be used to stop that tin cream is from the side leakage of wing both sides according to the condition of production.
Therefore, the utility model is because of having easily advantage such as replacings of adjustable angle and blade simultaneously, has beneficial effect significantly to enhancing productivity, reduce production cost and reducing aspect such as labour intensity.
