Description

Technical Field

[0001] This utility model relates to the field of badminton racket shaft polishing technology, and more specifically to an automatic polishing device for carbon fiber badminton racket shafts. Background Technology

[0002] Carbon fiber badminton racket shafts are characterized by low density, light weight, high strength of carbon fiber material, and resistance to deformation. Compared with traditional wooden badminton rackets, they are more durable and can reduce the burden on athletes' arms and wrists during exercise, thereby reducing the injury rate of badminton players.

[0003] After the carbon fiber badminton racket shaft is manufactured, it needs to be sanded and polished to remove burrs and smooth out any protrusions, making the racket smoother and more durable. The sanding process for badminton racket shafts currently involves the following steps: Cleaning: The carbon fiber badminton racket shaft to be sanded is thoroughly cleaned to ensure the surface is free of dust, oil, or grease; Initial sanding: The surface of the carbon fiber badminton racket shaft is manually sanded back and forth using coarse sandpaper or sanding blocks to remove larger burrs or uneven areas. During this process, the sander needs to maintain even pressure to avoid over-sanding and damaging the carbon fiber layer on the surface of the racket shaft; Fine sanding: After the initial sanding, the surface of the badminton racket shaft is sanded with finer sandpaper or sanding tools to further remove smaller burrs or imperfections. During this process, an appropriate amount of polishing compound can be applied to improve the sanding effect. The above manual sanding method for carbon fiber badminton racket shafts is tedious, time-consuming, and labor-intensive, wasting a significant amount of manpower.

[0004] Therefore, how to provide a device with a simple structure and reasonable design that can automatically polish the surface of carbon fiber badminton racket shafts is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0046] The connector 213 is not connected to the substrate 1.

Each sanding belt clamping mechanism 8 includes a cylinder 81, an upper strip-shaped clamping block 82, and a lower strip-shaped clamping block 83. The cylinder body of the cylinder 81 is fixed on the first plate surface 11, and the extension direction of its telescopic rod is arranged along the height direction of the gantry frame. The length direction of the upper strip-shaped clamping block 82 is perpendicular to the base plate 1. 1.

[0053] Under normal conditions, most of the sanding belt 100 is wound onto the take-up roller 72. When it is necessary to replace the grinding section of the sanding belt 100 between the upper sanding belt limit roller 41 and the lower sanding belt limit roller 42, first control the telescopic rod of the cylinder 81 to retract and open the corresponding sanding belt gap, so that the sanding belt 100 located between the sanding belt take-up mechanism 6 and the sanding belt moving guide roller 1 51 and the sanding belt 100 located between the sanding belt moving guide roller 2 52 and the sanding belt unwinding mechanism 7 are in a relaxed state. Start the take-up motor 61 and close the brake 71. At the same time, the unwinding roller 72 releases the sanding belt 100 and the take-up roller 62 winds up the sanding belt 100 to replace the grinding section of the sanding belt 100 located between the upper sanding belt limit roller 41 and the lower sanding belt limit roller 42.

The lower surface of the rotating plate 93 is fixedly connected to the top of the base plate 1. The rotation of the rotating plate 93 can drive the base plate 1 to rotate, causing the grinding section to rotate and grind the annular portion of the carbon fiber badminton racket shaft 200.

[0055] The motor mounting plate is connected to the crossbeam of the gantry frame via a connecting plate. The motor mounting plate remains stationary. The rotating motor 92 is fixed on the motor mounting plate, and its output shaft can drive the rotating plate to rotate in the horizontal direction. The rotating plate drives the base plate to rotate, which in turn drives the grinding section to rotate and grind the annular part of the carbon fiber badminton racket shaft 200.

The controller controls the extension rods of the two cylinders to extend, and the sanding belt located between the take-up roller and the sanding belt guide roller, and between the unwind roller and the sanding belt guide roller, is clamped and fixed in the corresponding sanding belt gap. Then, the controller starts the drive motor, and the sliding plate drives the moving strip to slide up and down along the height direction of the gantry through the connecting piece. The grinding section of the sanding belt between the upper and lower sanding belt limit rollers on the moving strip repeatedly polishes the badminton racket shaft.

[0058] When it is necessary to replace the grinding section of the sanding belt, firstly, use the controller to control the telescopic rods of the two cylinders to retract, opening the two sanding belt gaps; then, use the controller to start the winding motor and close the brake, so that the unwinding roller feeds the sanding belt while the winding roller feeds the sanding belt, thus completing the replacement of the grinding section between the upper and lower sanding belt limit rollers.

[0059] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
