Following-through device of table tennis serving machine

Abstract

The invention discloses a following-through device of a table tennis serving machine. The following-through device comprises supporting columns of a first guide pipe, wherein the supporting columns are welded on the left side and the right side of the bottom end of the first guide pipe, a second guide pipe is welded on the right side of the first guide pipe, a feeding port is formed in the left side of the top end of the first guide pipe through welding, sleeves are welded in the middles of the upper end and the lower end of the outer wall of the first guide pipe, and clamping blocks are arranged at the bottom ends of the insides of the sleeves. The following-through device of the table tennis serving machine can continuously deliver balls into the serving machine through matching betweena connecting rod and a top plate, the situation is avoided that the balls fall downward based on self weight and get stuck during delivery, the manual dredging operation performed by workers is omitted, the clamping blocks move down under the pressures of compression springs to make the balls stuck after the balls are pushed towards the right through matching between the compression springs and the clamping blocks, reverse ball rolling is prevented, and the demands of customers are met.

Description

technical field [0001] The invention relates to the technical field of ball delivery devices, in particular to a ball delivery device of a table tennis server. Background technique [0002] At present, most of the ball delivery devices of table tennis serving machines have the phenomenon of ball jamming, which is extremely inconvenient to use. In addition, the ball delivery devices of table tennis serving machines in the prior art need to be adjusted by manual mechanical adjustment when adjusting the operating parameters, which can neither be long-distance Remote control adjustment, also can not real-time monitoring of the working conditions in the ball delivery device, such as the patent application number CN200720051452.8, including machine base, ball delivery mechanism, ball storage bucket, middle channel connected with the lower channel of the ball storage bucket, hollow support rod , and the corresponding electric control part, the middle channel is connected with the h...

[0002] At present, most of the ball delivery devices of table tennis serving machines have the phenomenon of ball jamming, which is extremely inconvenient to use. In addition, the ball delivery devices of table tennis serving machines in the prior art need to be adjusted by manual mechanical adjustment when adjusting the operating parameters, which can neither be long-distance Remote control adjustment, also can not real-time monitoring of the working conditions in the ball delivery device, such as the patent application number CN200720051452.8, including machine base, ball delivery mechanism, ball storage bucket, middle channel connected with the lower channel of the ball storage bucket, hollow support rod , and the corresponding electric control part, the middle channel is connected with the hollow cavity in the support rod to form a ball delivery channel. The structure of this patent is complex and through the transmission of a gear and other structures, resulting in a higher cost of the machine. At the same time, the ball passes through the top plate of the machine When pushing to the right, the ball will fall down due to its own weight, causing the machine to break the ball due to the untimely delivery of table tennis balls, which is inconvenient for the staff to use, which affects the normal training of the user and cannot meet Customer demand
