Abstract

The utility model relates to a novel composite rubber tube blank core, which comprises an inner core (1), an elastic body (2) and a surface layer (3) of the core blank, wherein the elastic body (2) wraps up the inner core (1) to form a middle layer of the blank core; the surface layer (3) wraps up the elastic body (2) to form an outer layer of the blank core. The inner core (1), the elastic body (2) and the surface layer (3) are wrapped from inside to outside to form a cylinder forming the rubber tube blank core. The utility model overcomes the problems in the prior art that the blank core can be hard used for producing large-caliber lengthened rubber tubes, and the blank core is frequently broken in the rubber tube in the core stripping process because of insufficient hardness, causing low use rate and other problems, prolongs service life, simultaneously has the characteristics of high hardness and high bending property, and can be used for producing the large-caliber rubber tubes of infinite length.

Description

NEW TYPE OF COMPOSITE sebific duct base core

Technical field

The utility model relates to a kind of sebific duct base core that uses in the sebific duct production process, a kind of NEW TYPE OF COMPOSITE sebific duct base core that particularly uses in the production that adds long length hose and large-bore hose.

Background technology

At present, employed base core is generally iron core, rubber core or nylon core in the sebific duct production process.Iron core consumes a large amount of labours aborning, and cannot produce and add long length hose, produces 20 meters long sebific ducts general at most.Because of its hardness deficiency, the phenomenon in sebific duct of often occurring rupturing in the depoling process be a key link that produces substandard products, and utilization rate is low, generally uses and scraps for 30 times, has increased production cost in the middle of producing for rubber core.Nylon core is then because of the too high and incompatible production that adds long length hose and large-bore hose of its hardness.

The utility model content

In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of novel sebific duct base core that meets.

The technical solution of the utility model: a kind of NEW TYPE OF COMPOSITE sebific duct base core, comprise base in-core core 1, base core elastomer 2, base core top layer 3, the described base in-core core 1 of described base core elastomer 2 parcels forms base core intermediate layer, 3 parcels described base core elastomer 2 in described base core top layer forms base core skin, wrap up from inside to outside mutually in conjunction with constituting cylinder on described base in-core core 1, base core elastomer 2, base core top layer 3, forms sebific duct base core; Described base in-core core 1 is by steel wire rope and/or have high-intensity chemical fiber rope and twine mutually and constitute; Adopt binding agent to be connected and fixed between the described base in-core heart 1, base core elastomer 2, the base core top layer 3; The two ends of the described base in-core heart 1 are the sling structure.

The beneficial effects of the utility model: because the utility model has adopted base in-core core, the resistant to bending base core elastomer that adopts high-temperature resistant rubber with stretch-proof and adopted the heatproof engineering plastics or the base core top layer of temperature-resistant hard rubber formation, make prolong its service life, be more than 5 quilts of rubber base core, and the plastics of base core are reusable, and can produce the endless large-bore hose, not only appearance is hard has more the high crooked advantage that rubber base core had.

Specific embodiment

Below in conjunction with accompanying drawing the utility model is done further auspicious stating

As shown in Figure 1, a kind of NEW TYPE OF COMPOSITE sebific duct base core, comprise base in-core core 1, base core elastomer 2, base core top layer 3, base core elastomer 2 parcel base in-core cores 1 form base core intermediate layer, base core top layer 3 parcel base core elastomers 2 form base core skin, and base in-core core 1, base core elastomer 2, base core top layer 3 are adopted multilayer to extrude packaging type and wrapped up mutually from inside to outside in conjunction with constituting a solid cylinder.Also can be adhesively fixed together between inner core 1, the elastomer 2, outer 3 by adhesive.But its base core top layer 3 of sebific duct base core of the present utility model is flake-ofves, and after treatment, its base core top layer 3, inner core 1, base core elastomer 2 are still reusable.Base in-core core 1 is by many steel wire ropes and/or has the base in-core heart that high-intensity chemical fiber rope is intertwined mutually and constitutes, and the many steel wire ropes that are intertwined mutually or chemical fiber rope broken into the structure of sling at its two ends, with fixing.It is more remarkable that such structure makes that base in-core core has the stretch-proof performance, and more firm 3.Simultaneously, base core elastomer 2 also can be made of treated high-temperature resistant rubber and/or any rubber; Base core skin 3 can be made of heatproof engineering plastics and/or high temperature resistant vulcanie, wear-resisting, smooth, hard base core skin 3.The visual concrete condition of employed material requires and uses different matched combined in above-mentioned each layer of base core.
