Technical field
The utility model relates to a kind of extruder or extruding machine, particularly a kind of double-deck extruder head.The utility model is applicable to extruding of various common plasticses such as PVC, PE, HFFR, and the double-decker that is specially adapted to products such as oil platform cable and used in nuclear power station K3 nucleoid level cable is extruded.Belong to the electric wire production technical field.
Background technology
In the electric wire production technical field, often run into the insulation of special construction and requirement, bilayer as insulation is extruded, and how to guarantee that in bilayer is extruded the stable of each layer structure is very crucial, and the cable that use in some fields and place must adopt double-deck expressing technique.At present, the head of the extrusion equipment that adopts when double hyer insulation is extruded has generally comprised internal layer tripper, outer tripper, crosshead body, outer device for adjusting deviation, outer school mould screw, internal layer school mould screw, die sleeve seat, core rod and die sleeve, adopts the major defect of head to be when existing bilayer is extruded: (1) complex structure.Existing double hyer insulation extruder head will be finished bilayer and extrude, and generally to finish bilayer and extrude with two core rods and a die sleeve, so complex structure; (2) degree of eccentricity is regulated trouble, tuningout weak effect.In process of production, because the diversity of production specification and kind, therefore often need the more specification of mold exchange, existing double hyer insulation extruder head need readjust the degree of eccentricity behind each replacing mould specification, therefore very bothers, the tuningout weak effect, this has not only caused influence to production, and has wasted lot of manpower and material resources in tuningout work, inefficiency; (3) extrude the quality instability.Because influenced by human factor bigger for tuningout, can't guarantee to change the uniformity and the stability of tuningout behind the mould specification, the structural instability of each layer when therefore causing bilayer to be extruded is extruded inhomogeneously, extrudes of poor quality.
The utility model content
The purpose of utility model is the deficiency that exists in the above-mentioned technology, provide simple in structure, tuningout easily fast, tuningout is effective, extrude good, the applied widely a kind of double-deck extruder head of quality.
Realize that the above-mentioned purpose technical scheme is: a kind of double-deck extruder head, include the internal layer tripper, outer tripper, crosshead body, outer device for adjusting deviation, outer school mould screw, internal layer school mould screw, the die sleeve seat, core rod, die sleeve and die sleeve and cap, crosshead body is provided with internal layer glue-feeder and outer glue-feeder, also include middle mould, outer tripper inner surface matches by the conical surface with internal layer tripper outer surface and is connected, outer tripper outer surface matches by the conical surface with the crosshead body inner surface and is connected, core rod is connected the front end of internal layer tripper, die sleeve is arranged on outside the core rod, has extruding cavity between die sleeve and the core rod, the die sleeve seat is arranged on outside the die sleeve, internal layer school mould screw withstands on the external diameter of die sleeve seat, the die sleeve front end is provided with die sleeve and the cap that is connected with the die sleeve seat, middle mould is connected the front end of outer tripper, outer device for adjusting deviation is arranged on outside the middle mould, and outer device for adjusting deviation is connected with crosshead body, outer school mould screw withstands on the external diameter of outer device for adjusting deviation, has the internal layer gum intaking passage between outer tripper and the internal layer tripper, has outer gum intaking passage between outer tripper and the crosshead body, internal layer gum intaking passage and outer gum intaking passage are connected with extruding cavity at middle mould front end, the internal layer glue-feeder is connected with the internal layer gum intaking passage, and outer glue-feeder is connected with outer gum intaking passage.
Further, also include outer device for adjusting deviation pressure ring and head forward flange, by the device for adjusting deviation attachment screw at outer device for adjusting deviation pressure ring place outer device for adjusting deviation is fixedlyed connected with crosshead body, the head forward flange is fixedlyed connected with crosshead body by the forward flange attachment screw.
Further, described core rod is fixedly connected on the front end of internal layer tripper by screw thread, and middle mould is fixedly connected on the front end of outer tripper by screw thread.
Further, described internal layer tripper and outer tripper are fixed together by attachment screw and crosshead body.
Further, described outer school mould screw is connected with crosshead body by outer school mould screw adapter sleeve.
Further, described internal layer school mould screw is connected with crosshead body by internal layer school mould screw adapter sleeve.
Further, the radial centre lines of described internal layer glue-feeder and outer glue-feeder overlaps, and the position of internal layer glue-feeder and outer glue-feeder is at week of the excircle of crosshead body degree of differing upwards.
After adopting technique scheme, have a lot of benefits: (1) is simple in structure.The utility model is finished bilayer with a core rod and a die sleeve and extruded, and has lacked a core rod than existing technology, and is therefore simple in structure.(2) tuningout is easy, and tuningout is effective.The utility model carries out the adjusting of the internal layer and the outer degree of eccentricity by outer school mould screw and internal layer school mould screw, when the utility model bilayer is extruded, after the degree of eccentricity is adjusted, the degree of eccentricity can remain unchanged when replacing core rod and die sleeve changed specification, no longer need to regulate the degree of eccentricity, it is little influenced by human factor, so the utility model tuningout easily, fast, high efficiency; And can realize bilayer extrude in the independent tuningout of ectonexine, can also realize bilayer extrude in the independent adjusting of each layer physical dimension, the degree of eccentricity is below 5%, tuningout is effective.(3) it is good to extrude quality.Because influenced by human factor little for the utility model, guaranteed to change the uniformity and the stability of tuningout behind the mould specification, the Stability Analysis of Structures of each layer is extruded evenly during therefore double-deck extruding, and it is good to extrude quality; (4) has multi-functional.The utility model also can be realized individual layer and double-colored extruding at different middle mould, core rod and the die sleeves of replacing, have the multiple function of extruding, but a tractor serves several purposes is applied widely.
