Scraper plate 2 is right-angled trapezium harden structure, and bottom chamfer forms scraper plate base 19, and the middle part of scraper plate base 19 is equipped with opening
25.2 top of scraper plate is equipped with groove profile hole 24, and the angle between 24 axis of groove profile hole and scraper plate base 19 is α °, equal to upper clamp plate 3 with
For clamping plate 6 relative to the angle of inclination on scraper plate base 18,24 bottom of groove profile hole is equipped with the first scale 14.
First scale 14 is equipped with n small lattice, sin α=1/n, n >=2.Right end plate 7 is used for the screw thread of mounting and adjusting bolt 11
The second scale 15 is equipped with hole.7 second scale 15 of right end plate is equipped with m small lattice, is equal to 360 °/m, m >=2 per lattice angle.Scraper plate 2
2 bolts hole for installing upper clamp plate 3 are equipped with 10 top of back shroud, and lower part is equipped with for install lower clamp plate 62
Bolt hole, 2 bolt hole center's lines and 19 angle of scraper plate base are α °.
As shown in Figure 1, Figure 2, Figure 3 shows, assembling process of the invention specifically comprises the following steps：
(1) upper clamp plate 3 and lower clamp plate 6 are parallel to each other placement.First member plate 4 is installed on upper clamp plate 3 with right end plate 7 by screw
With 6 left and right ends of lower clamp plate, empty slot is formed.
(2) scraper 9 is fixed on before sliding block 8 by screw 13, and sliding block 8 is placed between upper clamp plate 3 and lower clamp plate 6, bullet
Spring 5 is installed between first member plate 4 and sliding block 8, and sliding block 8 can slide in groove, and elastic reset is realized by spring 5.Lower clamp plate 6
Groove 23 can avoid scraper 9 and walk row position.
(3) after above component assembly, upper clamp plate 3 and lower clamp plate 6 are installed between back shroud 10 and scraper plate 2 by bolt.
Upper clamp plate 3 is with lower clamp plate 6 relative to scraper plate base tilt alpha °.
(4) during initial position：The first pointer 16 on sliding block 8 just refers to 0 of first scale 14 on scraper plate 2, scraper
Base 19 (N faces) is just overlapped with scraper plate base 18 (M faces), and 8 direction of travel of sliding block is pressed from both sides with the N faces of scraper 9 and the M faces of scraper plate 2
Angle is a °, and sina=1/4.
(5) clamping screw 11 and adjustment bolt 12 are screwed into upper clamp plate 3 and the threaded hole of right end plate 7 and just contact respectively
Sliding block 8, at this time the second pointer 17 in adjustment bolt 12 just refer to 0 of the second scale 15 in right end plate, handle 1 is welded on
The top of upper clamp plate 3.
The course of work and operation principle of the present invention are：
(1) as shown in Fig. 4, Fig. 5, Fig. 6, adjustment bolt 12, pitch P=1mm of adjustment bolt 12, outer spiral shell are rotated clockwise
Line promotes sliding block 8 along the runner movement between upper clamp plate 3 and lower clamp plate 6 in the case where the internal thread of right end plate 7 is oriented to, while sliding block 8
Compress spring 5.Adjustment bolt 12 often rotates a circle, one pitch P of length direction traveling, i.e. 1mm.With the movement of sliding block 8, scrape
After window pulls open height H between the N faces of knife 9 and the M faces of scraper plate 2, clamping screw 11, the outer spiral shell of clamping screw 11 are rotated clockwise
For line in the case where the internal thread of upper clamp plate 3 is oriented to, pressed slider 8, prevents play.14 the+the second scale of reading of the numerical value of H=first scale
15 readings.14 big lattice width 4mm of the first scales of Fig. 5, corresponds to window height 1mm, has 4 small lattice between two big lattice, small lattice are wide
Spend and read small lattice for 1mm, corresponding window height 0.25mm, reading, reading is 2.25mm at present.The second scales of Fig. 6 are put down for 15 1 weeks
Divide 5 lattice, represent 0.05mm, one week 0.25mm per lattice, reading is 0.1mm at present；Window height H=2.25+0.1=2.35mm.
(2) as shown in fig. 7, spreading thickness is more than the metal dust 20 of 2.35mm on the base plate (21.The metal of original state
20 upper surface of powder is uneven, uneven thickness, is not suitable for rolling composite plate.The uniform distribution device of height will be adjusted from gold
Belong to powder 20 side scrape to opposite side, during uniform distribution device keep vertical with substrate 21, the M faces of scraper plate 2 and substrate
21 contacts, the N faces of scraper 9 strike off 20 upper surface of metal dust, and the metal dust 20 after striking off is uniformly and consistency of thickness.
(3) rotation clamping screw 11, another mistake hour hands rotation adjustment bolt 12, sliding block 8 are compressing the elastic force of spring 5 counterclockwise
Effect is lower to be resetted, and all scale zeros, the N faces of scraper 9 are just overlapped with the M faces of scraper plate 2, window height H zeros.
Present invention design is reasonable, compact-sized, simple and practical.The original slided using bolt rotation forces sliding block on inclined-plane
Reason raises scraper window height, and window is accurate, can repeatedly adjust arbitrary height use, not only make 20 thickness of metal dust uniform,
Rolling test effect is obviously improved, and can also arbitrarily adjust window height, extreme enrichment test data, and improve the reliable of data
Property.Manual safety simple and easy to use, is greatly saved experiment time, improves work efficiency, and equipment cost is extremely low,
Maintenance cost hardly occurs.Scale is determined according to the pitch of the angle and adjustment bolt of sliding block 8 and the formation of scraper plate base 18
Numerical value, makes accurate reading precision fully meet the required precision of experiment powdering thickness up to 0.05mm.And after repeatedly adjusting,
Numerical value is still precisely reliable, and convenient adjustment uses.On the basis of existing test model, it can be opened in powder rolling composite board production line
Hair can accurately adjust the uniform distribution equipment of powder thickness, improve the degree of automation of production line.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
