A glued sports ball piece edge folding machine

Abstract

The invention discloses a ball piece edging machine for an adhesive sports ball. The machine comprises a die and a pressing head, wherein the pressing head comprises an upper pressing head and a lower pressing head; the die which is a shaping die is mounted between the upper pressing head and the lower pressing head; synchronous hydraulic devices are mounted at the tail parts of the upper pressing head and the lower pressing head; the die is formed by integrating a large cavity and a small cavity; a heating copper tube is mounted at the inner side of the die; supporting feet are integrally formed at two ends of the die. According to the machine, the edging and adhering of all edges of a ball piece can be performed at a time, so that the labor intensity of workers can be reduced; due to the flow process, the ball piece can be directly manufactured at a time; the heating copper tube and a heating layer are used for heating the surroundings; the edging is performed after preheating, so that the edging quality can be ensured; meanwhile, the ball piece can be avoided damage during folding; when in heating and adhering, the surroundings are uniformly heated, so that the fineness and safety in the whole edging and adhering process can be ensured.

Description

technical field [0001] The invention relates to a ball nozzle, in particular to an adhesive sports ball piece edge folding machine, which belongs to the technical field of inflatable balls. Background technique [0002] Adhesive sports ball refers to the general term for balls that use adhesive to firmly bond the ball and the inner tube together, which is different from the stitched ball that uses stitches between the ball and the ball. Adhesive sports balls usually refer to three big balls namely football, volleyball and basketball. Adhesive sports ball: each piece of ball is relatively independently pasted on the surface of the inner tube, and a small amount of adhesive is applied to the contact between the ball and the ball to make them stick to each other and play a waterproof role. The inner tube of the adhesive sports ball alone bears the internal pressure and the external beating force during use; therefore, the inner tube is required to have high strength, and the i...

AI Technical Summary

Problems solved by technology

[0003] 1) Folding and pasting requires a lot of force, and workers are prone to fatigue. After fatigue, the strength decreases, which affects the quality of folding and pasting; also due to the high labor intensity, the turnover rate of production workers has always been relatively high, and they are often replaced. New workers, leading to instability in operating levels, resulting in fluctuations in product quality

[0004] 2) Due to the high elasticity of the elastic layer, when one side is folded and pasted, and then the other side is folded and pasted, the completed side is easy to crack under the action of elasticity, and it is difficult to fold and paste after cracking. cause waste

[0005] Chinese patent application number 201110435451.4 discloses an adhesive sports ball sheet folding machine, including a mold and a pressure head. The mold is composed of a bottom mold, a ring mold, and a top mold. The top mold is connected to the pressure head and is equipped with a high-frequency heating system. The periphery of the bottom mold is provided with a groove, the lower part of the ring mold is provided with a convex ring matching the shape and size of the groove, and the shape and size of the top mold are the same as the cavity in the middle of the ring mold; the upper surface of the bottom mold, the inner surface of the ring mold and The lower surface of the top mold is provided with a Teflon coating, which can prevent the mold from sticking to the ball, and the shape of the mold includes pentagon, hexagon, and five-pointed star; the present invention can fold and stick all the edges of the ball once, if the When three to five molds are connected together, three to five ball pieces can be folded and pasted at one time, and the size of the folded edges is accurate, the sticking force is consistent and uniform, and the folded edge of the ball piece is firmly pasted with the elastic layer. The quality of the glued sports balls produced is high, and the pass rate is also high; however, the above-mentioned technical solution has to undergo 180° flanging, and the flanging process is also cold-treated, which is prone to cracks. Even if the processing is completed, the quality of the ball will be reduced. quality
