Embodiment 1

[0025] The first purpose of the present invention is to provide a seamless table tennis ball with a skeleton. The shell of the seamless table tennis ball with a skeleton includes arc-shaped meridian bones 11, and a plurality of meridian bones 11 are surrounded into a ball shape. The two ends of the warp bone 11 are connected into one by the top cover 12 to form an elastic spherical skeleton 1, the skeleton 1 is provided with a fine mesh layer 2 integrated with the skeleton, the fine mesh layer is provided with an adhesive layer 3, and the adhesive layer is outer A PVC spherical shell 4 integrally formed by injection molding is provided.

[0026] As a preferred embodiment of the present invention, the thickness of the warp bone in the radial direction of the table tennis ball is one-fifth of that of the PVC spherical shell of the table tennis ball.

[0027] As a preferred embodiment of the present invention, both ends of the above-mentioned meridian bone 11 are provided with gr...

Embodiment 2

[0029] Seamless table tennis ball manufacturing process with skeleton. The steps are as follows:

[0030] The first step is bone building, using a 3D printer or molding to make the meridian bone 11 and the top cover 12, and assemble it into an elastic spherical skeleton 1,

[0031] The second step is spinning, using an extrusion spinneret to spray and solidify the hot-melt filaments on the skeleton 1, spraying multiple times and forming a fine mesh layer attached to the skeleton 1 and integrated with the skeleton 2;

[0032] The third step is to spray the mixed glue, ultrasonically crush the hot-melt PVC sheet into ultra-fine PVC material powder, mix the hot-melt glue powder and PVC material powder according to the volume ratio of 1:1-1:2, and add it to the ordinary Mix the glue in the glue and stir evenly to form a mixed glue, and then apply the mixed glue and form a partial penetration into the fine mesh layer to transition the mixed glue layer 3;

[0033] The fourth step...

Abstract

The invention discloses a seamless table tennis ball with a skeleton and a manufacturing technology thereof. A shell of the seamless table tennis ball with the skeleton comprises circular-arc longitude skeleton bodies. A spherical structure is defined by the multiple longitude skeleton bodies, and the two ends of the multiple longitude skeleton bodies are connected into a whole through top covers to form the elastic spherical skeleton; a fine net layer connected with the skeleton into a whole is arranged outside the skeleton; a glue connection layer is arranged outside of the fine net layer; a PVC ball shell integrally formed through injection molding is arranged outside the glue connection layer. The defects that a hemisphere-glue-type table tennis ball in the prior art is prone to damage, and the service life is not long; meanwhile, production steps are excessive, and consumed time is overlong are overcome.

Description

technical field [0001] The invention specifically relates to the technical field of sporting goods, in particular to a seamless table tennis ball with a skeleton and a manufacturing process thereof. Background technique [0002] The table tennis balls in the prior art mostly adopt two spherical shells made of hemispherical PVC material to be glued into a spherical shape by an adhesive. The process steps include cutting the PVC sheet into a spherical sheet, and then pressing the spherical sheet into a hemisphere Shape, and then the two halves of the hemispherical shape are in use, and the seams of the table tennis ball of this structure are extremely prone to damage. Even using more advanced adhesive formulations to reinforce both hemispheres will not prolong their lifespan. At the same time, the piecemeal steps of the whole production process are too long and time-consuming. Contents of the invention [0003] In view of the above problems, the invention provides a seamle...
