Ping pong ball serving machine

Abstract

The invention discloses a ping pong ball serving machine. The machine comprises a ball supplying device and a ball launching device, and the ball supplying device comprises a paddle wheel shell, a center paddle wheel, a ball storing disc and a paddle wheel electromotor; the paddle wheel shell is arranged at the lower portion of the ball storing disc, the center paddle wheel is arranged in the paddle wheel shell, and the paddle wheel electromotor is arranged in the bottom middle of the paddle wheel shell; an output shaft of the paddle wheel electromotor is connected with a rotary shaft of the center paddle wheel, two adjacent paddle blades of the center paddle and the inner wall of the paddle wheel shell jointly form a transferring position f one ping pong ball, and the launching device comprises a main shell, a ball delivering pipeline, a launching pipeline and a minitype air pump; the minitype air pump is arranged in the main shell, the ball delivering pipeline is placed under the paddle wheel shell, the two ends of the ball delivering pipeline are respectively connected with a ball outlet formed in the bottom of the paddle shell and a ball inlet formed in the launching pipeline,and an air outlet pipe of the minitype air pump is connected with an air inlet of the launching pipeline. The machine is higher in reliability, low in failure rate and more stable in ball serving.

Description

technical field [0001] The invention relates to a table tennis ball machine. Background technique [0002] Table tennis is our country's national sport, and it has a broad mass base in our country. With the popularization and development of table tennis, people's demand for table tennis teaching and training is also increasing. Serving and returning the ball are important game skills, which occupy a large proportion in normal training. People usually use the table tennis ball machine to simulate the opponent's serving and returning the ball, that is, two jump balls and one jump ball, to achieve the purpose of training. [0003] At present, most of the ball supply devices of table tennis serving machines on the market are squeezed from bottom to top. The principle is that most of them use two-wheel rotation, extrusion and friction to serve the ball. This method of serving the ball has unstable trajectory and cumbersome settings. It is difficult to simulate the coach's "feedi...

Problems solved by technology

[0003] At present, most of the ball supply devices of table tennis serving machines on the market are squeezed from bottom to top. The principle is that most of them use two-wheel rotation, extrusion and friction to serve the ball. This method of serving the ball has unstable trajectory and cumbersome settings. It is difficult to simulate the coach's "feeding" and the real person's return. The cost of table tennis ball machines on the market is high, often costing several thousand or even tens of thousands of yuan, which is unaffordable for ordinary players and training venues, which greatly hinders training
