Embodiment Construction

[0014] Such as figure 1 As shown: the upper part of the equipment casing is a mesh cylinder 1, and the lower part is a base with a plurality of fixing holes 2. The equipment casing 1 is only used to prevent the mold 3 from being blown away during the test run. It can be removed during normal production.

[0015] The positioning holder 4 is a pneumatic holding device, the upper part of which is a three-layer sleeve structure, that is, the inner tube 5, the middle tube 6 and the outer tube 7, and the sleeve structure may not be used, but directly connected by a hose through a pipe joint. To the corresponding position of the bowl body 19. The bottom of the positioning holder 4 is a bowl-shaped body 19, and its inner spherical surface coincides with the outer spherical surface of the mould. A positioning pin 8 is installed at the center of the inner tube 5 bottom. The positioning pin 8 can slide a certain distance in the inner tube 5 . The middle pipe 6 communicates with the ...

Abstract

A truly seamless reinforced table tennis production method and production equipment. A brand-new production method is proposed: the reinforcement material is mixed into the plastic at the same time (or only the plastic) is injected (or the seamed ball blank is loaded) into the spherical mold, and it is finally solidified in a full range of rotation according to a certain rule. A seamless hollow reinforced (or unreinforced) sphere of uniform wall thickness. The present invention proposes brand-new manufacturing equipment simultaneously. The production process of suction, movement, positioning, injection molding, suspension (or support) rotation and solidification of the spherical mold is realized. "Seamless" table tennis balls are now produced by gluing two hemispheres together with a seam inside. The vast majority of ping pong balls fail at their seams. The whole production will go through a dozen to thirty processes and a cycle of 50 to 150 days. The invention fundamentally eliminates the source of cracks in the table tennis ball and further strengthens the ball. The life of table tennis is greatly extended. Simultaneously, the production process is simplified and the production cycle is shortened.

Description

technical field [0001] The invention relates to a production method and equipment for a truly seamless reinforced table tennis ball and a hollow ball containing other organic compounds. This is a table tennis ball produced with special methods and special manufacturing equipment. Background technique [0002] The "seamless" table tennis balls being produced today are made by gluing the two hemispheres together and actually have a seam inside. In use, the vast majority of table tennis balls fail at their seams. Therefore, even if both hemispheres are reinforced, their service life will not be extended. The whole production will go through a dozen to thirty processes and a cycle of about 50 to 150 days. Contents of the invention [0003] The purpose of the invention is to replace the original production process with a new method and equipment to produce a truly seamless table tennis ball inside and outside. And strengthen the sphere, simplify the process and shorten the ...
