Summary of the invention

The technical problem to be solved in the present invention is to provide the undaform sieve plate that a kind of screening effect is good, simple in structure.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of undaform sieve plate, its key technology is: its by nano material through injection mo(u)lding, it comprises holder muscle and is disposed on side by side the grating on holder muscle, gap between adjacent grating forms the gap of screening materials carrying, and described grating shape is undaform.

Described undaform is continuous S type wave.

Grating concrete shape divides following three kinds of situations:

1, the be projected as S type wave of described grating in parallel compass screen surface direction, with the S type that is projected as wave (being that compass screen surface is S type wave) on grating parallel longitudinal and vertical compass screen surface place in-plane.

2, the S-shaped wave of the projection of described grating in the direction of parallel compass screen surface.

3, described grating with the S type that is projected as wave on grating parallel longitudinal and vertical compass screen surface place in-plane.

The above grating root is provided with knuckle with holder muscle junction, and this radius R2 is 0.5～0.8 ㎜.

In the time that grating is shaped as in the 1st situation, the wavelength L of its S type wave of projection in parallel compass screen surface direction is 100-120 ㎜, is being 100-120 ㎜ with the wavelength of the S type wave of projection on grating parallel longitudinal and vertical compass screen surface place in-plane.

Two drift angle places at the above grating top are circular arc chamfering, and the radius R 1 of this circular arc chamfering is 0.2-0.5 ㎜.

The transverse shape of the above grating is inverted trapezoidal, and its top chi width dimensions is 1-3.5 ㎜, and its oblique angle, side α is 5-15 °, and described adjacent two grating top clearance B are 0.1-3.5 ㎜, and the height T of described grating is 8-10 ㎜.

The above holder muscle transverse shape is arch, and its base width is that L1 is 10-12 ㎜, and the height of described holder muscle is that H1 is 10-20 ㎜.

The beneficial effect that adopts technique scheme to produce is:

1, this sieve plate grating be shaped as undaform, when screening each material jump up after drop point on the slope, repeated screening, can extend the time of staying of material on compass screen surface, improves screening effect;

2, this sieve plate is not hung fiber, is difficult for stopping up, and screening efficiency is high;

3, grating and holder muscle place are that knuckle and grating drift angle are that circular arc chamfering is optimized screening effect, and have improved the bonding strength of grating with holder muscle;

4, sieve plate is the injection mo(u)lding of nanometer synthetic material, and nonmagnetic, bar stitches evenly, and production technology is simple, production cost is low, price advantage is obvious;

5, conduct oneself with dignity little, wearability is high, long service life, when work noiselessness pollute.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be described in detail.

Referring to accompanying drawing 1-accompanying drawing 4, the present embodiment adopts nano material injection mo(u)lding, and its material can adopt the material such as polyformaldehyde, nylon, and its structure comprises holder muscle 3 and is set up in parallel the grating 2 on holder muscle 3, each grating 2 keeps at a certain distance away and is arranged side by side, and this is spaced apart the gap for screening materials carrying.Described grating 2 shapes are undaform, and described undaform is continuous S type wave.The be projected as S type wave of described grating 2 in parallel compass screen surface direction, and be also S type wave (being that compass screen surface is undaform) with the projection in the plane of grating 2 parallel longitudinals and vertical compass screen surface place in-plane.Described grating 2 roots are provided with knuckle with holder muscle 3 junctions, and this radius R2 is 0.5～0.8 ㎜, and it can solve grating 2 roots and hang the problem of fiber, and can strengthen grating 2 and the bonding strength that holds in the palm muscle.The wavelength L of the S type wave of projection in parallel compass screen surface direction is 100-120 ㎜, be 100-120 ㎜ with the wavelength of the S type wave of projection on grating 2 parallel longitudinals and vertical compass screen surface place in-plane, the party upwards size of wavelength specifically determines according to material.Two drift angle places at described grating 2 tops are circular arc chamfering, and the radius R 1 of this circular arc chamfering is 0.2-0.5 ㎜, are conducive to like this material in screening process and, by the gap between grating, improve screening efficiency.This sieve plate grating be shaped as undaform, when screening each material jump up after drop point on the slope of undaform, material, through repeated screening, can extend the time of staying of material on compass screen surface like this, improves screening effect.
