Abstract
The utility model provides an installing structure for a jewel spray nozzle of an inkjet printing machine. The installing structure comprises a jewel spray nozzle body and a metal embedding sleeve, wherein the metal embedding sleeve is provided with a flat bottom groove, the bottom of the flat bottom groove is provided with a through hole for spraying ink to pass through, a metal lining sleeve is embedded and fixed in the flat bottom groove of the metal embedding sleeve, the metal lining sleeve is provided with inner holes and passing holes, the inner holes are positioned on the same axial line and are mutually communicated, the passing holes are used for allowing sprayed ink to pass through, a position limiting step is formed between the hole bottom of the inner holes and the passing holes, the jewel spray nozzle body is in gap assembling in the inner holes of the metal lining sleeve, and two end surfaces of the jewel spray nozzle body are respectively in contact with the groove bottom of the flat bottom groove and the position limiting step at the hole bottom part of the inner holes. The installing structure has the advantages that the jewel spray nozzle body is in gap assembling in the metal lining sleeve, and the jewel spray nozzle body can be effectively prevented from fracturing in the assembly process; and in addition, the jewel spray nozzle body can also be ensured to have the enough embedding and matching force during the positive ink spraying and the reverse cleaning, and the jewel spray nozzle cannot fall off.
Description
Technical field
The utility model relates to a kind of mounting structure of ink jet numbering machine jewel nozzles.
Background technology
Referring to Fig. 4; The mounting structure of existing ink jet numbering machine jewel nozzles; Comprise that jewel nozzles body 1 is nested with metal 2, the material of metal nested 2 is a stainless steel, has a flat bottomed recess on the metal nested 2; The bottom of this flat bottomed recess has one and is used for the through hole that ink-jet water passes through; Said jewel nozzles body 1 is inlayed in the flat bottomed recess that is fixed on metal nested 2, and the through hole of the spray orifice of jewel nozzles body and flat bottomed recess has same hole heart line, and ink-jet water is successively from the through hole forward ejection from top to bottom of jewel nozzles body, flat bottomed recess.
Come off in order to prevent that the jewel nozzles body from putting from metal displacer; A kind of mode of taking is to make interference fit between the jewel nozzles body flat bottomed recess nested with metal; But because the thickness of jewel nozzles body has only 0.20 ~ 0.60mm; The jewel nozzles body is again a hard brittle material, and the jewel nozzles body is when assembling with metal is nested mutually, and this cognition of jewel nozzles more than 50% is broken; And because the scarf area is little, scarf power is not enough, and when the reverse cleaning of the jewel nozzles body being carried out from the bottom to top, the jewel nozzles body comes off from the nested flat bottomed recess of metal easily.
In order to solve the problem that the jewel nozzles body breaks, the technical staff has proposed another kind of technical scheme: the jewel nozzles body is cooperated with metal displacer cover gap, and be adhesively fixed with viscose glue.Though this structure can avoid the jewel nozzles body to break,, the perishable viscose glue of the ink-jet water capacity in use; Viscose glue was lost efficacy, and in addition, bond area is less; Bonding force is little; In the use, when the reverse cleaning of the jewel nozzles body being carried out from the bottom to top, the jewel nozzles body is same to come off from the nested flat bottomed recess of metal easily.
The utility model content
The technical problem that the utility model solves is: a kind of mounting structure of ink jet numbering machine jewel nozzles is provided, can prevents that the jewel nozzles body from breaking and coming off.
The technical scheme of the utility model is: a kind of mounting structure of ink jet numbering machine jewel nozzles; Comprise that the jewel nozzles body is nested with metal; Said metal displacer cover has a flat bottomed recess; The bottom of this flat bottomed recess has one and is used for the through hole that ink-jet water passes through, and it is characterized in that, inlays in the nested flat bottomed recess of said metal to be fixed with a metal lining; This metal lining have be positioned on the same axis and the endoporus that is interconnected be used for the via hole that ink-jet water passes through; Form limited step at the bottom of the hole of said endoporus and between the said via hole, said this body space of jewel nozzles is assemblied in the endoporus of metal lining, and the both ends of the surface of jewel nozzles body contact with the bottom land of said flat bottomed recess, the limited step of bottom, said endoporus hole respectively.
Said metal lining and interference fit between said metal is nested.
The via hole of said metal lining is turbination.
Clearance distance between the endoporus of said jewel nozzles body and said metal lining is 0.01mm～0.02mm.
Said metal material nested and said metal lining is stainless steel.
The beneficial effect of the utility model is: with respect to jewel nozzles body in the prior art directly inlay fixing or be adhesively fixed on metal nested in for; This body space of jewel nozzles of the utility model is assemblied in the metal lining, can prevent effectively that the jewel nozzles body from breaking in assembling process; And because metal lining is fixed in the nested endoporus of metal; Metal lining and reverse scarf between metal is nested; The both ends of the surface of jewel nozzles body contact respectively at the bottom land of flat bottomed recess, the limited step of bottom, endoporus hole; Thereby realize the fixing of jewel nozzles body, can guarantee that the jewel nozzles body all has enough scarf power in the forward ink-jet, when oppositely cleaning, can not come off.

Fig. 4 is the prior art constructions sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1～Fig. 3, a kind of mounting structure of ink jet numbering machine jewel nozzles comprises jewel nozzles body 1, metal nested 2 and metal lining 3.Metal nested 2 has a flat bottomed recess 2a, and the bottom of this flat bottomed recess 2a has one and is used for the through hole 2b that ink-jet water passes through, and metal lining 3 is inlayed and is fixed among the nested flat bottomed recess 2a of metal interference fit between the metal lining 3 nested with metal 2.Metal lining 3 has the endoporus 3a that is positioned on the same axis and is interconnected and is used for the via hole 3b that ink-jet water passes through; Form limited step 3c at the bottom of the hole of endoporus 3a and between the via hole 3b; Jewel nozzles body 1 gap is assemblied among the endoporus 3a of metal lining; The both ends of the surface of jewel nozzles body 1 contact with the bottom land of flat bottomed recess 2a, the limited step 3c of bottom, endoporus hole respectively, thereby make jewel nozzles body 1 all realize spacing fixing in the direction of its two end faces.The via hole 3b of metal lining is turbination.Clearance distance between the endoporus 3a of jewel nozzles body 1 and metal lining is 0.01mm, and according to the change in size of jewel nozzles body 1, the clearance distance between the endoporus 3a of jewel nozzles body 1 and metal lining also can be 0.02mm.The material of metal nested 2 and metal lining 3 is stainless steel, and stainless steel material can prevent the ink-jet aqueous corrosion.
