Problems solved by technology

This makes the positive and negative rotation of the head of the ball machine around the Y rotation axis uncoordinated. During the rotation, the rotational speeds of the forward rotation and the reverse rotation are inconsistent, which brings a bad experience to the user.
At the same time, it also affects the service life of the motor to a certain extent.

Embodiment Construction

[0028] refer to Figure 1 to Figure 10 , an intelligent table tennis ball server of the present invention includes a server head 1 that can rotate around the Y axis, the front end of the server head 1 is provided with a serving wheel 2 and a motor 3 that drives the serving wheel 2 to rotate, wherein the serving wheel 2 includes an upper serving wheel and a lower serving wheel, and the motor 3 is coaxially arranged with the serving wheel 2 for driving the serving wheel 2 to rotate. The rear end of the ball machine head 1 is provided with a counterweight 4. Under the balance of the counterweight 4, the center of gravity of the ball machine head 1 and the rotation center line 5 of the Y-axis are located in the same vertical plane. like figure 1 As shown in , the rotation centerline 5 of the Y-axis is perpendicular to this section. Preferably, the weight and position of the counterweight 4 can be adjusted and set so that the center of gravity of the head 1 of the ball machine fa...

Abstract

The invention discloses an intelligent table tennis serving machine, which comprises a table tennis serving machine head capable of rotating around a Y axle, wherein the front end of the table tennisserving machine head is provided with table tennis serving wheels and motors driving the table tennis serving wheels to rotate; the back end of the table tennis serving machine head is provided with abalancing weight; and the gravity center of the table tennis serving machine head and a rotating center line of the Y axle are positioned on the same vertical plane. Under the effect of the balancingweight, the gravity center of the whole table tennis serving machine head is regulated again, so that the gravity center of the table tennis serving machine head and the rotating center line of the Yaxle are positioned in the same vertical plane; the resistance required to be overcome by a driving motor is enabled to be consistent when the table tennis serving machine head does positive rotationand reverse rotation around the Y axle; on one hand, the service life of the motor is favorably prolonged; on the other hand, the rotating speed when the table tennis serving machine head does positive rotation and reverse rotation around the Y axle is enabled to be consistent as much as possible; and good experience is brought to users.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to an intelligent table tennis ball server. Background technique [0002] In order to meet the needs of table tennis trainers or entertainers for rotating the ball, a pair of serving wheels are generally arranged at the front end of the server head of the table tennis server. At different rotational speeds, the spinning balls that meet the needs can be manufactured. [0003] Since the two teeing wheels need to control their respective rotational speeds independently, two independent motors need to be provided to realize the driving of the teeing wheels. The weight of the two balls at the front end of the head of the ball machine and the two motors themselves are relatively large, resulting in an unbalanced weight of the head of the ball machine, and the center of gravity is located on the left side of the Y axis of rotation. Due to the large weight of the front end of the...
