Rotary controllable table tennis ball serving machine

Abstract

The invention discloses a rotary controllable table tennis ball serving machine. The machine comprises a shell and a pipeline, a motor frame is arranged at the upper end of a motor, the motor is fixedly connected with the motor frame, and the upper end of the motor frame is fixedly connected with the shell; a sliding groove is formed in the right side of the upper end of the shell, and a sliding block is arranged on the inner wall of the sliding groove; the sliding groove is in sliding clamped connection with the sliding block, a hollow cylinder is arranged in the middle of the sliding block,and the hollow cylinder is in sleeved connection with the shell. According to the rotary controllable table tennis ball serving machine, through the cooperation of the shell and the pipeline and the cooperation of the shell, an air inlet and a fan, it can be guaranteed that served balls rotate and the speeds of the served balls are the same, and the served balls can be conveniently used for training; through the cooperation of the shell and the sliding groove, the cooperation of the sliding groove and the sliding block and the cooperation of the sliding block and the hollow cylinder, the length of a ball outlet can be adjusted to change the movement distance of the table tennis balls, then the rotation speeds of the served balls are changed, and it is guaranteed that the served balls are suitable for different degrees of training.

Description

technical field [0001] The invention relates to the technical field of table tennis training, in particular to a table tennis ball machine with controllable rotation. Background technique [0002] Table tennis is a sports project with a broad mass base. When athletes are training or competing in table tennis, the most common problem is to bend over to pick up dropped table tennis balls, which not only wastes time, but also causes unnecessary exercise and increases the burden on athletes. Therefore, in order to meet people's table tennis training requirements, there have been many inventions related to table tennis ball serving devices, such as the patent for invention with application number 201520035943. The blower for blowing table tennis, the air outlet of the blower is provided with a table tennis blowing pipe, although the problem of multiple trainings has been solved, it can ensure that the equipment can automatically discharge the ball, the rotation of the ball can b...

When athletes are training or competing in table tennis, the most common problem is bending over to pick up dropped table tennis balls, which not only wastes time, but also causes unnecessary exercise and increases the burden on athletes

Therefore, in order to meet people's table tennis training requirements, there have been many inventions related to table tennis ball serving devices, such as the patent for invention with application number 201520035943. The blower for blowing table tennis, the air outlet of the blower is provided with a table tennis blowing pipe, although the problem of multiple trainings has been solved, it can ensure that the equipment can automatically discharge the ball, the rotation of the ball can be guaranteed, and the speed of the ball is the same. It is convenient for training and use. You can adjust the length of the ball outlet, change the distance of the table tennis ball, and thus change the rotation speed of the ball. The problem of ensuring that it is suitable for different levels of training cannot be solved.
