Preparation process of improved racket

Abstract

The invention relates to the technical field of rackets, and discloses a preparation process of an improved racket, which comprises the following steps: step one, taking a carbon fiber plate or a glass fiber plate, sewing and bonding the carbon fiber plate or the glass fiber plate on an integrated solid EPP material through colloid, and pressing again through pressure equipment; Step 2, the pressed primary product is made into the external structural shape of the required racket by a cutting machine, and it is cleaned; Step 3, put the cleaned racket prototype into a UV printer to draw the surface pattern or attach the surface with water marks. By adjusting the internal material of the racket to the integrated solid EPP material, the prepared racket can be prevented from being deformed, and at the same time, the elastic performance is improved.

1 . A process for preparing an improved racket, comprising the following steps:
 Step 1, sewing and bonding involving a carbon fiber plate or a glass fiber plate being sewed and bonded onto an integrated solid EPP material using colloid, followed by being pressed again by a pressure device;   Step 2, making the pressed primary product into the external structural shape of the required racket by a cutting machine and cleaning it;   Step 3, putting the cleaned racket prototype into a UV printer for drawing the surface pattern or attaching the surface with water marks;   Step 4, assembling the racket prototype with the surface pattern drawn in step 3, protecting the edge strip, the back cover, and the handle cover.   
     
     
         2 . The preparation process of an improved racket according to  claim 1 , characterized in that in step 1, epoxy resin glue is used as the colloid. 
     
     
         3 . The preparation process of an improved racket according to  claim 1 , characterized in that in step 1, the integrated solid expanded polypropylene is made of polypropylene material, and the density of the polypropylene material is 0.01 g/cm-0.05 g/cm. 
     
     
         4 . The manufacturing process of an improved racket according to  claim 1 , characterized in that in step 2, the rotating speed of the cutting machine is 1750-3000 r/min, and the cleaning time is 25-30 min. 
     
     
         5 . The manufacturing process of an improved racket according to  claim 1 , characterized in that in step 4, the thickness of the protective edge strip is 2 mm-3 mm.
