Sport ball and sport ball making method

Abstract

The invention discloses a sport ball and a sport ball manufacturing method. The sport ball comprises four layers of a rubber liner, a wrapping yarn layer, a gluing layer and a leather layer, wherein the wrapping yarn layer is arranged on the surface of the rubber liner, the exterior of the wrapping yarn layer is covered by the gluing layer, the raw material of the gluing layer is raw rubber sheets, and the gluing layer is vulcanized and glued to the outer leather layer for integration. According to the invention, the sport ball is divided into four layers, the wrapping yarn layer is arranged on the rubber liner, the exterior of the wrapping yarn layer is covered by the gluing layer, the gluing layer is vulcanized and glued to the outer leather layer, and the leather layer is composed of aplurality of leather sheets forming the surface of the sport ball. The gluing layer and the leather sheets are subjected to low-temperature rapid vulcanization treatment to be integrated into a whole,no glue adhesive is used, thus the environment friendliness and firmness of the product are improved to a greatest extent on the aspects of production and use; and no sewing line is used, and productmanufacturing is automatically finished through a mold, thus labor costs are saved and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of ball sporting goods, in particular to a sports ball and a method for making the sports ball. Background technique [0002] Rubber sports balls such as footballs and volleyballs are common sports balls and are widely used in ball sports. The surface of the football is usually spliced ​​by 32 pieces, including 12 pieces of regular pentagonal pieces and 20 pieces of regular hexagonal pieces. According to different manufacturing techniques, footballs can be divided into rubber footballs, sewn footballs and hand-adhesive footballs. The rubber football is made of rubber through rubber mixing into pieces, pasted in the mold by hand, and then directly vulcanized under high temperature and high pressure. The surface of the ball is a whole, and the lines on the surface are pressed. Because this technology is formed by direct thermal vulcanization of rubber, the texture is hard, the roundness is poor, and the rubber smell i...

AI Technical Summary

Problems solved by technology

[0003] The applicant aims at the disadvantages of the above-mentioned existing sports ball manufacturing process that the skins or the skin and the inner layer are independent of each other, the connection is not firm, easy to crack and damage, the manufacturing process is complicated, and the production efficiency is low. A sports ball with a reasonable structure and a production method for the sports ball can realize the integral molding of the inner layer of raw rubber and the leather layer through vulcanized bonding, improve the firmness and reliability of the leather on the surface of the ball, simplify the manufacturing process, and improve production efficiency
