Description

Pickleball racket structure with surface layer with changing texture and manufacturing method thereof

The invention relates to a method of thermoforming changing textures of different roughness on the surface of a thermoplastic resin by pressurizing a molding mold with molding textures, and solidifying the changing textures into a solid state through cooling. The changing textures are used to effectively control the racket. The main body has a progressively changing hitting surface friction in order to increase the hitting spin force of the racket body and increase the number of hits.

Press, the frame of a traditional pickleball racket is made of wood, while the racket is made of aluminum core, foam core, honeycomb core and composite materials. In a more traditional wooden or aluminum structure, the racket board is entirely made of these materials. , and cut into the desired finished shape. To complete the clapper, additional wood, aluminum or other materials are used to build the handle to increase its girth. However, this process will limit the weight-to-strength ratio and customized weight, balance, etc. Traditional clapperboards are made from solid wood, injection molding, or composite fiber with a honeycomb core. However, it is known that most of the surface of pickleball rackets is a smooth surface with no friction. It is difficult to achieve the skill of turning and hitting the ball when used. Even if the surface of the later improved racket is integrated with surface roughness texture, however, the roughness is not used when using it. After a long time, its texture will wear out and fail to produce better friction.

Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop an innovative structure that is more ideal and practical and can meet the ardent expectations of consumers is also the goal and direction that relevant industries must work hard to develop and break through; in view of this , the creator has many years of experience in the manufacturing, development and design of related products. After detailed design and careful evaluation based on the above goals, he finally arrived at a truly practical invention.

That is, the main purpose of the present invention is to provide a pickleball racket structure with a surface layer with changing textures and a manufacturing method thereof; the problem to be solved is that most of the surface of the racket with a conventional structure is smooth and has no scratches. The frictional surface makes it difficult to achieve the skill of cutting and hitting the ball when used. Even if the surface of the later improved racket is integrally molded with surface roughness patterns, however, after the roughness is used for a long time, the patterns will wear away and cannot produce better friction. The problem of force action is overcome; the present invention mainly uses a racket body made of carbon fiber material, and at least one racket surface of the racket body forms a cavity, and the inside of the cavity is combined with a surface layer, which contains There is a thermoplastic resin thermoformed on top of the surface layer. The surface of the thermoplastic resin is in a semi-cured state and is pressurized through a molding mold with molding textures to thermoplastically mold changing textures of different roughness on the surface of the thermoplastic resin, and is cooled. The changing texture that is solidified into a solid state can effectively control the progressively changing hitting surface friction of the racket body through the changing texture, so as to increase the hitting spin force of the racket body and increase the number of hits.
