A kind of anti-package covering plate structure
Technical field
This utility model relates to the technical field of rubber manufacturing machinery, is specially a kind of anti-package covering plate structure.
Background technology
Structure now with anti-package cover plate is shown in Fig. 1, and it includes body construction 1 ', copper mesh structure 2 ', and it inhales vacuum by copper mesh structure 2 ' so that is attached to the tire sidewall material of body construction 1 ' and is sucked and be attached on body construction 1 ', the shortcoming of this structure:
1) uneven distribution in irregular shape is expected on sidewall, often produces gas leakage by this kind of structure suction vacuum and causes that absorption sidewall is bad.
2) the densely covered aperture in copper mesh structure uses time length to have and blocks phenomenon, thus affecting adsorption effect, and then makes material easy landing during laminating on drum.
Summary of the invention
For the problems referred to above, this utility model provides a kind of anti-package covering plate structure, and it guarantees the adsorption effect that sidewall is expected by tire, and can steady in a long-term use, it is therefore prevented that material is landing during laminating on drum.
A kind of anti-package covering plate structure, its technical scheme is such that it and includes body construction, it is characterized in that: the center indent of the end to be fit of described body construction forms groove, it is placed with rubber blanket in described groove, the surrounding of described rubber blanket is close to four sidewalls of described groove, the bottom face of firm described groove is pasted by intrinsic viscosity in the bottom of described rubber blanket, and the upper surface of described rubber blanket flushes in the upper surface of described body construction.
It is further characterized by bonding reinforcing further by vulcanizing treatment after described rubber blanket is placed in described groove and fits, it is ensured that the bonding firmness of rubber blanket and body construction, promotes the viscosity of rubber blanket upper surface simultaneously;
The upper surface of described rubber blanket is smooth without decorative pattern, it is ensured that the rubber blanket degree of adhesion to material;
The hollow depth of described groove is not less than 2mm, and the thickness of described rubber blanket is the hollow depth of described groove;
Described groove is specially rectangular recess, and described rubber blanket is the rubber blanket of rectangular shape.
After adopting technique scheme, in actual production, the natural characterization of adsorption of rubber product is considerably increased the absorption roused sidewall by this anti-package cover plate by rubber blanket, guarantee the adsorption effect that sidewall is expected by tire, and can steady in a long-term use, it is effectively prevented material landing during laminating on drum, decreases suction vacuum equipment compared with existing structure, simplify structure, enhance adsorption effect.

In Fig. 2, Fig. 3, the title corresponding to sequence number is as follows:
Body construction 1, groove 2, rubber blanket 3.
Detailed description of the invention
A kind of anti-package covering plate structure, see Fig. 2: it includes body construction 1, the center indent of the end to be fit of body construction 1 forms groove 2, rubber blanket 3 it is placed with in groove 2, the surrounding of rubber blanket 3 is close to four sidewalls of groove 2, the bottom of rubber blanket 3 is by the bottom face of intrinsic viscosity patch jail groove 2, and the upper surface of rubber blanket 3 flushes in the upper surface of body construction 1.
Rubber blanket 3 bonds reinforcing further by vulcanizing treatment after being placed in groove 2 and fitting, it is ensured that the bonding firmness of rubber blanket 3 and body construction 1, promotes the viscosity of rubber blanket 2 upper surface simultaneously;
The upper surface of rubber blanket 3 is smooth without decorative pattern, it is ensured that the rubber blanket 3 degree of adhesion to material;
The hollow depth H of groove 2 is not less than 2mm, and the thickness of rubber blanket 3 is the hollow depth H of groove 2;
Groove 2 is specially rectangular recess, and rubber blanket 3 is the rubber blanket of rectangular shape.
Above specific embodiment of the utility model is described in detail, but content has been only the preferred embodiment that this utility model is created, it is impossible to be considered for limiting the practical range that this utility model is created. All equalizations made according to this utility model creation application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
