Abstract
The present invention discloses a kind of seamless table tennis manufacturing process, its step is as follows：The first step, makes bone, is integrally formed formula elastomeric spherical skeleton using what 3D printer printed circular warp bone and Duo Gen wefts bone composition, second step, spinneret, the filament of the state of hot melt is sprayed and is set on the skeleton；3rd step, sprays epoxy glue, by hot melt PVC sheet ultrasonic grind into ultra tiny PVC material powder, by hot melt adhesive powder and the PVC material powder according to 1:1‑1：2 volume ratio mixing, and is added in common glue and stirs evenly to form mixture glue, afterwards be coated with epoxy glue and forms partly that penetrating into transition epoxy glue in fine and closely woven stratum reticulare connects layer；4th step, condensation；5th step, injection molding.The hemisphere adhesive type table tennis for solving the prior art is easily damaged, and the service life is not grown, while production stage is excessive, takes the shortcomings that long.
Description
Technical field
Present invention relates particularly to sports goods technical field, is specially a kind of seamless table tennis manufacturing process.
Background technology
The table tennis of the prior art sticks into ball using spherical shell made of two hemispherical PVC materials by adhesive glue more
Shape, its processing step include PVC board being cut into spherical sheet material, then spherical sheet material hot melt is molded into hemispherical, then by hemisphere
The two halves of shape are in use, and the seam of the table tennis of such a structure is easily damaged.Even if using more advanced gluing formula,
Two hemisphere are all reinforced, also not
Its service life can be extended.The scrappy step of whole production process is long at the same time, takes long.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of seamless table tennis manufacturing process.Solve the hemisphere glue of the prior art
Viscous type table tennis is easily damaged, and the service life is not grown, while production stage is excessive, takes the shortcomings that long.
Present invention aims at provide a kind of seamless table tennis manufacturing process.
A kind of seamless table tennis manufacturing process, its step are as follows：
The first step, makes bone, is printed using 3D printer and is made of more parallel circular warp bone and Duo Gen weft bones
Be integrally formed formula elastomeric spherical skeleton,
Second step, spinneret, using squash type spinneret machine, the filament of the state of hot melt is sprayed and is set on above-mentioned skeleton,
Repeatedly spray and formed the fine and closely woven stratum reticulare for being attached to that above-mentioned skeleton is outer and is connected with skeleton；
3rd step, sprays epoxy glue, by hot melt PVC sheet ultrasonic grind into ultra tiny PVC material powder, by hot melt adhesive
Powder and above-mentioned PVC material powder are according to 1:1-1：2 volume ratio mixing, and be added in common glue and stir evenly to be formed
Mixture glue, epoxy glue is coated with afterwards and forms part penetrate into transition epoxy glue in fine and closely woven stratum reticulare and connect layer；
4th step, condensation, the semi-finished product in the 3rd step are placed into condensation chamber and are condensed；
5th step, by semi-finished product be placed into by two it is hemispherical close up in the spherical shell mould formed, then by injection molding machine to
The PVC material of molten condition is injected between semi-finished product and spherical shell type mould, is cooled into seamless spherical shell 3 afterwards, is molded, deburring,
It can obtain with being integrally formed and seamless table tennis completely.
Further, up and down endpoint of the injection hole of above-mentioned injection molding machine in above-mentioned spherical shell mould.
Further, above-mentioned injection molding machine injection temperature is 150-200 degree.
Further, the material of above-mentioned skeleton is high-temperature resistance plastice, including LCP, and above-mentioned high-temperature resistance plastice hot melting temperature is high
In above-mentioned PVC material hot melting temperature.
Further, the hot melting temperature of above-mentioned filament is greater than or equal to above-mentioned PVC material hot melting temperature.
Beneficial effect
A kind of seamless table tennis manufacturing process provided, table tennis manufacturing process compared with prior art, the present invention are provided
Processing step is few, and manufacture is quick, can form completely seamless table tennis, while effectively prevent table tennis there are skeleton in table tennis
Pang ball damages.
