Product.
Such as Chinese utility model patent（Application number：201520719354.1, the applying date：2015.09.16）Disclose one kind
It is suitable to quick-replaceable inner tube of a tyre, including：Two ends are provided with the inner tube of a tyre body in the wedge-shaped fracture of mutual wedging, including the fracture is suitable to
Tire body mutual wedging after circularizing, the surface of the inner tube of a tyre body is parallel along its length to be provided with many linear reinforcements
Muscle, the surface of the inner tube of a tyre body is provided with many ring stiffeners along caliber direction.The utility model is made using the structure of fracture
Electric bicycle change the inner tube of a tyre when need not dismantle wheel, only need to by the inner tube of a tyre it is deflated after fracture is separated, you can take out the inner tube of a tyre；
Meanwhile, the reinforcement of inner tyre surface also makes the inner tube of a tyre be difficult displacement when in use, it is ensured that its service life.
The quick-replaceable inner tube of a tyre developed in the prior art, it is shorter than traditional closed-loop shape inner tube of a tyre service life in use, mainly
It is at non-closed loop sealing two ends and more fragile nearby, can not meet the requirement that people use for a long time, and price and tradition
The loop-like inner tube of a tyre compares no advantage.
The content of the invention
In order to solve above-mentioned technical problem, it is an object of the present invention to provide a kind of quick assembling inner tube of a tyre, the present invention
Second purpose be to provide a kind of preparation method of the quick assembling inner tube of a tyre, the method is suitable to high-volume high efficiency production, quickly
The assembling inner tube of a tyre is used for the damping of the vehicles such as bicycle, electric motor car, and the vibrations for making people be subject under steam are greatly decreased, carry
Rise the convenience of comfortableness and replacing.
In order to realize first above-mentioned purpose, present invention employs following technical scheme：
A kind of quick assembling inner tube of a tyre, the inner tube of a tyre includes setting the inner tube of a tyre cylinder of valve cock, and the two ends of described inner tube of a tyre cylinder are distinguished
By docking, film closed inner tube cylinder is set.Certainly the material of described film is identical with inner tube of a tyre cylinder, it would however also be possible to employ with
The similar material of inner tube of a tyre cylinder.
As a further improvement, described film length is 10 ~ 20mm, width is the ± 1mm that inner tube of a tyre cylinder puts down folded width,
Thickness puts down the 95% ~ 105% of folded thickness for inner tube of a tyre cylinder.
In order to realize first above-mentioned purpose, present invention employs following technical scheme：
A kind of method for preparing the quick assembling inner tube of a tyre, the method comprises the following steps：
1）Extruder, joint die orifice extrudes cylindric inner tube of a tyre cylinder, with cutting open after collection, or cuts open online；
2）Flat shape of the mouth as one speaks extrusion mould-outlet is made, small-sized mill is extruded, and directly extrudes film, cuts shaping；
3）Dock splicer docks inner tube of a tyre cylinder and film；
4）Vulcanized using indirect type vat, sulfuration steam 0.7 ~ 0.9MPa of external pressure, air 0.3 ~ 0.5MPa of internal pressure, cure time:
45~60min。
A kind of method for preparing the quick assembling inner tube of a tyre, the method comprises the following steps：
1）Extruder, joint die orifice extrudes cylindric inner tube of a tyre cylinder, with cutting open after collection, or cuts open online；
2）Flat shape of the mouth as one speaks extrusion mould-outlet is made, small-sized mill is extruded, and directly extrudes film, cuts shaping；
3）Dock splicer docks inner tube of a tyre cylinder and film；
4）The unnecessary sealing in green tire two ends after joint is reduced, using direct-type mold cure, sulfuration steam external pressure 1.1 ~
1.5MPa, air 0.8 ~ 1MPa of internal pressure, 3 ~ 5min of cure time.
The present invention proposes a kind of more stable non-closed inner tube of a tyre production technology of service life, to inner tube of a tyre sealing two ends knot
Structure has carried out rational improvement, simplifies the difficulty that end socket is engaged with carcass, reduces its process complexity and difficulty of processing, carries
High speed of production and efficiency, reduce cost.By the physical and chemical performance to test specimen, air-tightness and endurance quality
Deng test, requirement of the national standard to such product is complied fully with.The product and its manufacturing process have low cost of manufacture, use
The advantages of long lifespan, the potentiality of the traditional closed-loop formula inner tube of a tyre are substituted with part.
