Manufacturing method of eccentric ball

Abstract

The invention relates to a manufacturing method of an eccentric ball. The manufacturing method comprises the following steps: preparing a plurality of hemispherical shells; preparing a plurality of eccentric counter weights; placing two hemispherical shells, coating an adhesive, and placing eccentric counterweight pieces on the inner walls of the hemispherical shells; attaching the edges of the two hemisphere shells to each other to be combined into a sphere, wherein the eccentric balance weight piece is located in the sphere; and placing the ball body on the bearing disc, starting the ultrasonic oscillation welding machine to generate ultrasonic oscillation energy, transmitting the ultrasonic oscillation energy to the bearing disc, welding the contact area of the eccentric balance weight piece and the ball body due to friction, then fixing the eccentric balance weight piece to the inner wall of the ball body, and forming the eccentric ball. The eccentric ball can be applied to any hollow ball game, and by means of the eccentric characteristic of the eccentric ball, the eccentric ball generates a drifting effect during flying so as to create an entertainment effect.

Description

technical field [0001] The present invention relates to a manufacturing method of an eccentric ball, in particular, at least one eccentric weight is fixed on the inner wall of the sphere to achieve the purpose of changing the position of the overall center of gravity, and the fixed position of the eccentric weight can be determined according to actual needs, thus creating A very special and interesting entertainment effect is produced, which is very suitable for interesting competitions of ball games using hollow balls. Background technique [0002] In many occasions, various games are often used to create a joyful atmosphere, such as land games and treasure hunting games, especially through interesting competitions to make unfamiliar people interact during the competition, so as to quickly establish a tacit understanding. [0003] As we all know, challenging levels are usually specially designed in fun competitions and completed in teams by unfamiliar people. However, it i...

Problems solved by technology

[0008] However, the disadvantage of the prior art is that the use of glue to fix the counterweight will affect the preset degree of eccentricity due to the weight of the glue, especially for the weight of billiard balls, the glue itself is quite heavy.

In addition, the user cannot determine the position of the counterweight according to actual needs, and of course the counterweight cannot be fixed just before the fun competition, so the overall fun and entertainment cannot be further increased.

Furthermore, a well-trained player can get familiar with the characteristics of the eccentric ball through several back and forth shots or practice, and then gain an advantage, so the original purpose will be greatly reduced
