Liner of ball sports product and manufacture method thereof as well as ball sports product

Abstract

The invention discloses a manufacture method for the liner of a ball sports product, which comprises the steps as follows: materials for injection moulding are prepared; corresponding dies are prepared according to the required ball sports varieties; the materials for injection moulding in step one are formed into hemispheroid shells through an injection moulding machine provided with the dies in step two; a bulb is fixed on one hemispheroid shell; and two hemispheroid shells are stuck on the edges by adopting a way of hot melting. The manufacture method for the liner of the ball sports product has the advantages of simplified manufacture procedure and high productivity effect. The invention also discloses a liner of the ball sports product and the ball sports product.

Description

technical field [0001] The invention relates to the technical field of ball game production, in particular to a ball game liner, a manufacturing method thereof and a ball game product provided with the liner. Background technique [0002] Generally, the inflatable sports ball liner is made of materials such as artificial or natural rubber as the main component. In order to prevent the ball from expanding or deforming due to the increase of inflation pressure, the commonly used methods are as follows: wrap yarn or stick cloth on the surface of the rubber liner , and another is to add a cloth bottom on the bottom surface of the outer cladding material. Although the above methods can achieve a certain effect, the process is complicated and requires a large number of equipment, processes and personnel to cooperate. Moreover, after the rubber products are vulcanized at high temperature, the molecular structure of the material has changed, resulting in a low recycling rate. In ad...

Problems solved by technology

Although the above methods can achieve a certain effect, the process is complicated and requires a large number of equipment, processes and personnel to cooperate. Moreover, after the rubber products are vulcanized at high temperature, the molecular structure of the material has changed, resulting in a low recycling rate.

In addition, rubber raw materials must be mixed with various additives (such as sulfur, etc.) before they can be used after high-temperature vulcanization. During the vulcanization process, pollution will be generated and stench will be emitted when burning, and it will also cause allergic damage to a small number of human beings.
