Description
Technical field:
The utility model relates to a kind of kneading device of nano-zirconia powder, specifically relates to optical fiber ceramic and connects in the making of plug-in unit nano zircite contact pin, the mixing technology field of nano-zirconia powder.
Background technology:
At present, Fiber connection commonly uses nanometer zirconium oxide ceramic contact pin, in nanometer zirconium oxide ceramic contact pin production process, a technical process must be had, by nano zirconium oxide powder and suitable organic carrier evenly mixing, become applicable injection molding existing certain fluidity, have again the contact pin stock of some strength, so that lower road carries out injection moulding.
In the injection molding powder of composition nanometer zirconium, existing nano zircite zirconium powder, has again several organic binder bond, surface modifier, mixing derivant, lubricant, plasticiser etc.Because nanometer zirconium powder and above-mentioned macromolecule organic aggregate into one, stickiness is very strong afterwards, add that nanometer zirconium powder particle diameter is thin, be easy to reunite, so in mixing process, larger shearing force device must being used, making the mixing nano-zirconia powder of gained by mixing powder when overcoming high viscosity, produce distortion and fully stir, agglomerated particle in zirconium powder is pulverized, makes mixingly fully to carry out, material good fluidity.
Double roll mill is nano-zirconia powder mixing roll conventional at present, existing nano-zirconia powder mixing roll, the main mixing roller adopting ellipse, its ubiquitous defect is: when mixing materials is mixing in double roll mill, when stickiness improves, a part of batch mixing can be bonded on roll, and rotates with roll, does not participate in mixing.So just have impact on mixing effect, reduce mixing.
Utility model content:
The purpose of this utility model is to provide one and can effectively solves in nano-zirconia powder mixing process, and mixing materials is bonded in the problem on roll, and structure is simple, uses easy to operate, the kneading device of a kind of nano-zirconia powder that melting effect is good.
The technical scheme that the utility model is taked is as follows:
A kind of kneading device of nano-zirconia powder, comprise mixing case, it is characterized in that: two rollers are installed in mixing case, two rollers match, and roller is cylindrical, comprises turning cylinder and roll body, the outer circumference surface of roll body is provided with some grooves, above roller, be provided with comb tablet, comb tablet one end is provided with some scoops, scoop and groove suitable.
Further setting is:
Be built-in with nano-zirconia powder at mixing case, in the outside of mixing case, heater be installed.
Opposite direction rotating made by two rollers in mixing case.
Described comb tablet is installed on mixes on box body, and preferably, comb tablet is installed on the box body inwall that mixes.
Groove is offered along the longitudinal even level of roll body, and described scoop is evenly arranged at comb tablet one end, and scoop and groove one_to_one corresponding, scoop stretches in groove.
The groove width of groove is 25-30mm, and the groove depth of groove is 15-20mm, and the spacing of groove is 5-8mm.
The width of described scoop progressively reduces along head to bottom, and the curved design in two ends, left and right, forms lageniform discharge orifice between adjacent scoop.
The widest part of scoop is 23-28mm, and the narrowest place is 18-23mm.
The widest part of discharge orifice is 28-33mm, and interlude is 23-28mm, and eck place is 6-10 mm.
The beneficial effects of the utility model are as follows:
1, adopt cylindrical roller, be provided with groove at the excircle of roller, coordinate scoop and the discharge orifice of comb tablet simultaneously, effectively can solve the problem of powder bonding.
2, by the setting of the groove depth to groove, width, spacing, coordinate the effect of comb tablet, effectively improve melting efficiency.
Below by way of the drawings and specific embodiments, the utility model is described further:
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the mated condition figure of the utility model roller and comb tablet.
Detailed description of the invention:
As shown in Figure 1 and Figure 2, the kneading device of a kind of nano-zirconia powder of the present utility model, comprise mixing case 1, in the outside of mixing case 1 mixing case 1, heater 6 is installed, mixing case 1 is built-in with nano-zirconia powder 4, is provided with two rollers, 2, two rollers 2 and matches in mixing case 1, and make opposite direction rotating, thus drive powder 4 to rotate, shear, mixing.
Shown in composition graphs 2, roller 2 of the present utility model is cylindrical, comprises turning cylinder 21 and roll body 22, and the outer circumference surface of roll body 22 is evenly provided with some grooves 23, in the present embodiment, groove 23 is offered along the longitudinal even level of roll body 22, and groove 23 is set to 9, considers the melting efficiency of powder 4 and is not easy bonding, through experiment, the groove width of groove 23 is preferably 25-30mm, and the groove depth of groove 23 is preferably 15-20mm, and the spacing of groove 23 is 5-8mm.
Comb tablet 3 is provided with above roller 2, comb tablet 3 is installed on mixes on case 1 casing, preferably, comb tablet 3 one end is installed on case 1 cabinet wall that mixes, and comb tablet 3 other end is provided with in evenly distributed some scoops 31, scoop 31 is suitable with groove 23, scoop 31 can extend in the groove 23 of roller 2, and preferably, the width of scoop 31 is slightly less than the groove width of groove 23, thus scoop 31 can be inserted in groove 23, and the powder in groove 23 is cleaned out.
In the embodiment of fig. 2, scoop 31 is designed to width and progressively reduces to bottom along head, and namely the head of scoop 31 is large, bottom is little, the curved design in two ends, left and right, form lageniform discharge orifice 32 between adjacent scoop 31, the head of discharge orifice 32 is little, bottom is large.The advantage of such design is: on the one hand, scoop 31 can complete, neatly the powder in groove 23 is rooted out, by the powder rooted out via the top of discharge orifice 32 and through arc inner wall, again enter into and mix in case 1 casing, because discharge orifice 32 is in lageniform design, therefore, the powder after striking off also can not be caused to result in blockage in hole.
As preferred scheme, the widest part of scoop 31 is 23-28mm, and the narrowest place is 18-23mm, and the widest part of discharge orifice 32 is 28-33mm, and interlude is 23-28mm, and eck place is 6-10 mm.
In the embodiment of Fig. 1, Fig. 2, the groove 23 that two rollers 2 mixed in case 1 casing are offered is mutually corresponding, embodiment as replacing: the groove 23 that two rollers 2 mixed in case 1 casing are offered, can be mutually not corresponding yet, namely slot direction, width etc. is not identical, but the groove 23 on each roller 2, must and corresponding comb tablet 3 on scoop 31 and discharge orifice 32 corresponding, the i.e. quantity of groove 23 and width, with the scoop 31 in comb tablet 3 and discharge orifice 32 quantity and width suitable.
The course of work of the present utility model and principle as follows:
When the nano-zirconia powder 4 mixed with organic carrier is poured in mixing case 1, opposite direction rotating made by roller 2 with groove 23, thus drive powder 4 to be embedded in the groove 23 of roller 2 in A district, along with the rotation of roller 2, after powder is brought to B district, scraped by the scoop 31 in comb tablet 3, powder 4 is by the discharge orifice 32 in comb tablet 3, get back to again A district from B district, thus complete the mixing process be once sheared.So repeatedly, powder 4 is under the condition heated by mixing case 1 shell heater 6 simultaneously, is repeatedly repeated shear extrusion, accepts mixing, until reach mixing materials requirement, complete the calendering process process of nano-zirconia powder.
