Embodiment Construction
[0034] In order to have a clearer understanding of the technical solutions, objectives and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0035] The mechanized ball manufacturing method of the present invention can manufacture various types of balls, such as basketballs, volleyballs, footballs or rugby balls, etc., and is not limited to the types of balls exemplified in the following embodiments.
[0036] For clearly illustrating the method for the mechanization of the present invention, please refer to Figure 1A and 1B The step flow chart of this embodiment is illustrated with basketball as an example.
[0037] First, prepare an inner tube 10, such as Figure 1A As shown, a yarn layer 20 is formed by winding the yarn around the inner tire 10 to form a wound inner tire. The yarn layer 20 can form a protective layer similar to a cocoon to protect the inner tu...

Abstract
A method for mechanized manufacturing of rubber balls, comprising preparing a wire-wound inner tube; wrapping a middle tire on the peripheral surface of the wire-wound inner tire, the middle tire is made of rubber; preparing a middle tire vulcanization mold, placing the middle tire Carry out the vulcanization treatment of the middle tire in the vulcanization mold for the middle tire to form a vulcanized middle tire; prepare a vulcanization mold for the outer tire, the inner wall of the vulcanization mold for the outer tire is formed with a plurality of convex lines, and the plurality of skins are arranged on the The inner wall surface of the tire vulcanization mold, and a plurality of said skins are adjacently arranged, and an adhesive is coated on the surface of the skins facing away from the tire vulcanization mold, and the material of the skins is polyurethane placing the vulcanized middle tire in the vulcanization mold for the outer tire and contacting the surface coated with the adhesive with the skin sheet, and then performing vulcanization treatment on the vulcanized middle tire and the skin sheet to make a plurality of said skins The leather sheet is vulcanized into a seamless skin layer and attached to the vulcanized middle tire, and a plurality of grooves corresponding to the raised lines of the vulcanization mold of the outer tire are formed on the skin layer to obtain a rubber ball.
Description
technical field [0001] The invention relates to a method for manufacturing a ball, especially a method for mechanized manufacturing of a ball. Background technique [0002] Balls can be mainly divided into rubber balls and leather balls, which are classified and named after the outermost material. Generally speaking, the production process of a rubber ball is to paste a layer of artificial leather (such as polyurethane) on the surface of the rubber ball to make the ball have a better touch. [0003] In order to facilitate the description of the manufacturing process of traditional artificial leather balls, the following uses basketball as an example to illustrate, and please refer to Figure 3A and 3B shown. [0004] The traditional mechanized method of making a ball is to prepare an inner tube 90 first, such as Figure 3A As shown, the yarn is evenly wound on the inner tire 90, so that a yarn layer 91 is formed on the peripheral surface of the inner tire 90; then a middle...
