Problems solved by technology

[0002] Traditional basketball is divided into rubber balls and adhesive balls. Adhesive balls are commonly used. Generally, adhesive balls are made by manually bonding the ball skin to the inner tank. However, it is not easy to develop skilled workers, and the labor cost is rising year by year.
Therefore, some manufacturers have invented machine-sticking basketballs. For example, patent CN100491101C discloses a kind of machine-sticking basketball manufacturing process. The use of chloroprene graft glue in this process is not conducive to environmental protection, and has the risk of degumming and hidden dangers of skin warping; the process of attaching basketball to the machine is complicated; the use of glue to bond the bladder and the leather sheet requires inflatable packaging during transportation. If the suction becomes a vacuum, it is easy to open the glue, so the transportation volume is too large
[0003] In addition, the patent CN103935058A discloses a process for machine-attached basketballs. This process consists of splicing two hemispherical skins into a ball skin, and wraps the outer surface of the entire basketball liner with the ball skins. The seams will affect the appearance, and in the production process, the seams will not be completely sealed, and the rubber of the bladder will overflow from the seams, which will affect the authenticity rate; the basketball surface has no rubber thread stems and is completely sealed. Wrapped in leather, when the ball is bouncing, it is cushioned by the leather ball sheet, and its first bounce height and second rebound height are affected; moreover, this process also requires a layer of glue on the leather sheet, which is not conducive to Environmental friendly

Embodiment 1

[0029] The invention provides a manufacturing process of a basketball, comprising the steps of:

[0030] (1) Wrap the basketball liner with a layer of yarn with a yarn winding machine, and then wrap it with rubber with a laminating machine to form a bladder blank;

[0031] (2) Cut the high-temperature-resistant TPU into 8 pieces according to the shape of the sphere, and each piece of basketball skin has the same shape and equal area to form a basketball skin;

[0032] (3) Put the basketball skins obtained in step (2) into two hemispherical molds of the forming machine respectively, the molds are provided with prominent wire stems, and the basketball skins are evenly placed on both sides of the wire stems; Arrange the basketball skins close to the two hemispherical molds, put the bladder blank obtained in step (1) into any hemispherical mold of the arranged basketball skins, close the hemispherical molds, and heat Pressurization makes the rubber of the bladder blank semi-melt,...

Embodiment 2

[0036] The invention provides a manufacturing process of a basketball, comprising the steps of:

[0037] (1) Wrap the basketball liner with a layer of yarn, and then wrap it with rubber. The rubber compound contains 2.6 kg of sulfur per 100 kg of rubber compound, and the amount of accelerator (including TT, DM, M and other chemical auxiliary materials) is 2.6 kg . Forming a bladder blank;

[0038] (2) Cut the high-temperature-resistant PU leather into 14 pieces according to the shape of the sphere to form a basketball skin; paste a pattern on the outer surface of the basketball skin with thermal transfer paper;

[0039] (3) put the basketball skin sheet that step (2) obtains into two hemispherical moulds, be provided with protruding wire stem in the mold, the width 6mm of wire stem, the height 2mm of the wire stem in the hemispherical mould, basketball The skins are evenly placed on both sides of the line stem; the basketball skins are placed close to the two hemispherical m...

Embodiment 3

[0042] The invention provides a manufacturing process of a basketball, comprising the steps of:

[0043] (1) Wrap the basketball liner with a layer of yarn, and then wrap it with rubber. The rubber compound contains 1.5 kg of sulfur per 100 kg of rubber compound, and the amount of rubber compound contains 1.5 kg of accelerator (including TT, DM, M and other chemical auxiliary materials). . Forming a bladder blank;

[0044] (2) According to the shape of the sphere, the PU leather resistant to high temperature of 200 ℃ is cut into 4 pieces to form basketball skins. Each basketball skin has the same shape and area; pattern on paper;

[0045] (3) the basketball skin sheet that step (2) is obtained is put into respectively in two hemispherical moulds, and the mold is provided with protruding wire stems, the width 4mm of wire stems, the height 0.5mm of the wire stems in the hemispherical mould, The basketball skins are evenly placed on both sides of the wire stem; the basketball ...

Abstract

The invention relates to a manufacturing technology of a basketball. The manufacturing technology comprises the steps that firstly, a layer of yarn is wound on a basketball liner, then, the basketballliner is wrapped with rubber, a basketball liner workblank is formed, and vulcanization is not carried out; basketball skin pieces are bonded on the basketball liner workblank through heating and compression; and finally, vulcanization is carried out, so that the basketball skin pieces and the basketball liner workblank are bonded more firmly. The manufacturing technology has the beneficial effects that design of the basketball is reasonable, glue is not utilized, and the technology is more environmentally-friendly; vacuum package and transportation can be adopted, and transportation efficiency is improved; the basketball bounces higher, and rebound is more powerful; and bonding is firmer, and degumming and skin wrapping problems are avoided.
