Problems solved by technology
In order to improve the strength and roundness of the bladder, and the firmness of the combination between the bladder and the outer skin, in the prior art, a yarn layer or a fabric layer is added outside the bladder during the production process of the bladder, so there is a winding Defects such as unevenness, inconsistent thickness, winding can not be tightly attached to the bladder and easy to loosen
Although some of the existing bladders have at least a reinforced surface, and some bladders are divided into several chambers to maintain the firmness and pi of the bladder, the preparation method of this bladder is more complicated and the cost is higher
In addition, the bladder will inevitably have defects such as bladder deformation, bladder leakage, etc. during the production process. How to quickly detect and automatically remove the leaking and deformed unqualified bladders is an urgent problem to be solved in the current technology.
[0003] Although some of the existing bladders have at least a reinforced surface, and some bladders are divided into several chambers to maintain the firmness and pi of the bladder, the preparation method of this bladder is more complicated and the cost is higher

Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing of description and embodiment:
[0026] Such as figure 1 As shown, the preparation method of the bladder with a sandwich structure comprises the following steps:
[0027] The steps of mixing rubber:
[0028] Put the raw materials into the warehouse for proportioning, plasticize, knead, and knead the proportioned materials, and filter them through the extruder.
[0029] After mixing in the open mill, the material is cooled to form black glue;
[0030] Bladder forming steps:
[0031] The beaten black rubber is mixed through an open mill, and after mixing, it is pressed into a tablet and cut, and then the pressed piece is punched by a machine, and the ball seat is pasted, and it is formed by a bow-shaped pressing machine, and then in the The patch on the sphere is inflated and filled with mouth;
[0032] Sulfur detection steps:
[0033] Put the formed bladder into the vulcani...

The invention discloses a preparation method of a ball bladder with a sandwich structure. The preparation method comprises a rubber mixing step, a ball bladder forming step, a vulcanization detection step and a ball bladder winding step. The invention further discloses an inflation detection device and method for the ball bladder with the sandwich structure, and a ball bladder winding method. The ball bladder with the sandwich structure prepared by the preparation method disclosed by the invention is firm, good in circular degree, uniform in yarn winding, and uniform in thickness; the yarn tightly clings to the ball bladder without easily becoming loose; in addition, with the adoption of the preparation method, whether the ball bladder has air leakage or not, and whether the ball bladder deforms or not, can be effectively detected, the unqualified ball bladders can be rapidly and automatically eliminated, so that the manufacturing efficiency of the ball bladder, and the yield of the yarn-winded ball bladders are improved.
Description
technical field [0001] The invention relates to a ball product, in particular to a method for preparing a ball bladder with a sandwich structure. The invention also relates to a method for preparing the bladder with a sandwich structure, an inflation detection device, an inflation detection method, and a bladder winding method. The made bladder described in the present invention is suitable for various sports balls, especially for football and basketball. Background technique [0002] Sports balls, or balls, include footballs, basketballs, volleyballs, and other balls with similar structures. Its structure is that the outer layer is leather-sewn ball skin (or called outer ball skin, spherical shell or spherical surface, etc.), and the inside of the ball skin is equipped with an inflated bladder (or called: inner bladder or inner bladder). ), the bladder is generally made of rubber and has an inflation tube. The skins of modern sports balls are generally sewn from multiple...
