Abstract

The invention discloses a production process of a carbon fiber badminton racket, which is characterized by comprising the following steps of: mixing short-fiber-shaped carbon fibers and nylon according to a ratio to form a material of an injection-molded badminton frame; a material for injection molding of the ball frame is conveyed into an injection molding machine, and meanwhile the racket rod connected with the ball frame and the threading protective sleeve fixed in the ball frame are installed into a ball frame injection mold and are integrated through injection molding of the injection mold; polishing the racket rod and the racket frame which are formed into a whole through injection molding, and meanwhile, supplementing soil to the incomplete part; painting the outer surfaces of the bat rod and the bat frame after the soil is supplemented; and after painting is completed, threading, tightening, handle assembling and packaging are carried out. Granular carbon fibers and nylon are mixed in proportion, the racket frame and the racket rod are integrated through injection molding through an injection mold on an injection molding machine, after injection molding is completed, only the outer surface needs to be slightly polished, soil is supplemented, and therefore the production steps are reduced, the production complexity of the carbon fiber badminton racket is reduced, and the production efficiency is improved.

Description

Technical Field

[0001] The invention relates to the technical field of badminton rackets, in particular to a production process of a carbon fiber badminton racket. Background Art

[0002] In the production process of carbon fiber badminton racket, it is necessary to fold carbon fiber cloth into thin strips, then wrap the thin strips around the outside of the ball frame model, and use the carbon fiber tee to fix the racket shaft and the thin strips to form a preliminary carbon fiber racket frame, and then put the carbon fiber racket frame into a molding machine to fix it with resin. When heated, the resin will adhere to the carbon fiber racket frame, and workers need to use a scraper to scrape off the resin on the carbon fiber racket frame. After scraping, it is necessary to punch holes on the carbon fiber racket, which increases the process steps of racket production, increases the complexity of the process, and reduces the production efficiency. To this end, a production process of a carbon fiber badminton racket that can improve production efficiency is proposed. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems and to provide a production process for a carbon fiber badminton racket.

[0004] In order to achieve the above object, the present invention provides the following technical solution: a production process of a carbon fiber badminton racket, characterized in that the production process steps are as follows: 1) Mix short fiber carbon fiber and nylon in proportion to form the material for the injection molding ball frame; 2) The material of the ball frame is transported to the injection molding machine, and the racket shaft to be connected to the ball frame and the threading protective cover in the fixed ball frame are directly installed into the ball frame injection mold, and are injection molded into one piece through the injection mold; 3) Polish the racket shaft and racket frame which are injection molded into one piece, and fill the damaged parts with soil; 4) Paint the outer surface of the racket shaft and the ball frame after the soil is puttyed; 5) Thread the racket strings and tighten the strings on the painted racket frame; 6) Assemble the handle at one end of the racket shaft to form a complete badminton racket, and then package the assembled badminton racket.

[0005] Preferably, during the injection molding of the ball frame, the racket shaft and the threading protection sleeve are installed as injection molding inserts in the injection molding cavity of the injection mold before the injection molding.

[0006] Preferably, the racket shaft may be made of carbon fiber, steel or aluminum alloy.

[0007] The beneficial effects of the present invention are as follows: by mixing short-fiber carbon fiber and nylon in proportion, the ball frame and the racket shaft are injection-molded into one piece through an injection mold on an injection molding machine, and after the injection molding is completed, only a slight polishing and fillering is required on the surface, thereby reducing the production steps, reducing the complexity of carbon fiber badminton racket production, and improving production efficiency.

[0008] By installing the threading protection sleeve as an injection molding plug-in in the injection molding cavity of the injection mold before injection molding, it is no longer necessary to punch holes after the ball frame is injection molded, thereby reducing the production process steps and improving the production efficiency. DETAILED DESCRIPTION

[0009] The following is a further description of the production process of a carbon fiber badminton racket according to the present invention.

[0010] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0011] A production process for a carbon fiber badminton racket, characterized in that the production process steps are as follows: 1) Mix short fiber carbon fiber and nylon in proportion to form the material of the injection molded ball frame; by using granular carbon fiber, the granular carbon fiber can be directly mixed with nylon and transported to the injection molding machine for heating and melting, thereby improving the convenience of use; 2) The material of the injection-molded ball frame is conveyed into the injection molding machine, and the racket shaft and the threading protection cover are installed in the injection cavity of the injection mold as the injection molding plug-in before injection molding. Then the injection mold is closed, and the injection molding machine heats and melts the material of the injection-molded ball frame and injects it into the mold cavity of the injection mold. After the injection mold is cooled under pressure, the injection molding machine drives the injection mold to open the mold, so that it is injection molded into one piece through the injection mold; by installing the threading protection cover in the injection cavity of the injection mold as the injection molding plug-in before injection molding, there is no need to punch holes after the ball frame is injection-molded, thereby reducing the production process steps and improving the production efficiency. 3) Use sandpaper to polish the outer surface of the racket shaft and ball frame that are injection molded into one piece. After polishing, fill the damaged areas on the outer surface of the racket shaft and ball frame caused by injection molding to ensure the smoothness of the outer surface of the racket shaft and ball frame; 4) Then paint the outer surface of the racket shaft and the ball frame after the soil is put on to improve the appearance of the racket shaft and the ball frame; 5) After painting, connect the racket strings to the racket frame, and use the string tightening equipment to tighten the racket strings; 6) Then assemble the handle at one end of the racket shaft to assemble a complete badminton racket. The racket shaft can be non-retractable or retractable when the handle is installed. Finally, the assembled badminton racket is packaged.

[0012] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
