Pneumatic Table Tennis Serve Machine

Description of Invention

The machine powered by gas has a vertical plexiglass tube (convenient for observing but can be replaced by other tubes of same size) which serves the ball、 and a slant ball delivery pipe connecting the ball storage shed and the serving tube. As a result of a negative pressure produced by gas flow、 the ball will be sucked by pressure into the delivery pipe、 and according to the Bernoulli effect、 it will be blown up and rotating in the serving tube. At the top of the tube、 there is a baffle where the ball becomes "rotating ball" in various angles、 and the final ejection angle depends on the angle of the baffle. Then what is the creation motive for this table tennis serving machine? It is mainly
because that ordinary table tennis serving machines are not only highly costing high but are also prone to have ball jamming. In contrast、 the gas powered table tennis serving machine with a simple structure can remarkably reduce the probability of failure and ball jamming. The baffle、 fixed at the top of the ball serving tube by hot melt adhesive、 can adjust the direction of angle horizontally and vertically to realize spatial and adjustable control、 and can adjust the flip angle automatically according to needs by the program setting. Pipe docking is realized by hanging the shape of the pipe opening and sticking、 while the ball storage shed is a hollow carton with a hole on its top.
