Problems solved by technology

The gauze also has a certain degree of ductility, so the edge of the gauze is easy to wrinkle and loosen after lamination.
[0004] In addition, since the inner tank is made of black rubber, there is an environmental pollution problem during production, which cannot be completely avoided even if butyl rubber is used
And the surface of the inner tank must be wrapped with yarn, otherwise the inner tank cannot withstand the air pressure deformation after inflation, causing the ball to bulge out of round and cannot be used

Embodiment 1

[0042] refer to Figure 1-5 A hollow sphere 100 described in this embodiment includes two hemispherical shells 10; each hemispherical shell 10 includes an embryo body 11, a gauze and an outer shell 13; the embryo body 11 is molded by chemical fiber gauze through heating The method is formed into a hemispherical embryo body, the embryo body 11 has a hemispherical cavity 111, and the hemispherical cavity 111 has an opening 112 that runs through the end face where the center of the embryo body is located; the gauze is wound on the embryo body 11 A plurality of weft yarns 121 on the outer surface and a plurality of warp yarns 122 wound on the outer surface of the embryo body 11 constitute; the shell 13 is a hemispherical shell injection-molded on the outer surface of the gauze of the embryo body 11 by a thermoplastic elastic material; The two hemispherical shells 10 are thermally welded to form a closed hollow sphere 100 .

Embodiment 2

[0051] The characteristics of this embodiment are: in the manufacturing method of the hollow sphere, in step 2), when winding the weft yarn and the warp yarn, the second fixing method of the yarn is: the yarn is drawn out from the hot-melt glue nozzle, and the hot-melt glue automatically Viscose yarn is formed after injection in the nozzle, and the viscose yarn is compounded with yarn and attached to the embryo body; others are the same as in Example 1.

Embodiment 3

[0053] The characteristics of this embodiment are: in step 2), the winding method of winding the warp yarn: by moving the hot melt glue nozzle along the longitude direction of the embryo body, the yarn compounded with viscose yarn is wound on the outer surface of the embryo body , forming a number of warp yarns; the winding method of winding weft yarns: the embryo body rotates and gradually rises and falls, so that the yarn is automatically and continuously wound on the outer surface of the embryo body to form several weft yarns. Others are identical with embodiment 2.

Abstract

The invention relates to a hollow ball body and a manufacturing method as well as a movable ball adopting the hollow ball body. The hollow ball body comprises two semispherical shell bodies, wherein each semispherical shell body comprises a blank body, a gauze mesh and a shell; the blank body is molded into a semispherical blank body by a heating and die pressing method through chemical yarn and fabric; the blank body is provided with a semispherical cavity; the semispherical cavity is provided with an opening penetrating through the end face of the spherical center of the blank body; the gauze mesh is formed by a plurality of weft yarns wound on the outer surface of the blank body and a plurality of warp yarns wound on the outer surface of the blank body; the shell is a semispherical shell formed by carrying out injection molding on the outer surface of the gauze mesh of the blank body through a thermoplastic elastic material; and the two semispherical shell bodies are connected through a holt melting manner to form the sealed hollow ball body. The hollow ball body has the characteristics of environment-friendly materials, simple structure, rapidness in molding, good roundness and high strength.

Description

technical field [0001] The invention relates to a hollow sphere, in particular to a hollow sphere, a manufacturing method and a sports ball using the hollow sphere. Background technique [0002] The molding method of hollow sports balls such as basketballs is to first make an inner container, then wrap yarn on the inner container, and then place it in a spherical shell (also called a middle tire) that is sewn or otherwise formed. Its structure usually includes: inner tank, that is, the bladder, in the innermost part of the ball, usually made of black rubber or butyl rubber; yarn winding, the surface of the inner tank is evenly wound with yarn and dipped with glue to coat the yarn, and the inner tank Form a protective layer like a silkworm cocoon, or fit gauze on the surface of the inner tank instead of winding yarn to ensure the roundness after inflation; the spherical shell, the supporting structure between the inner tank and the skin, is made of rubber material; The ball ...
