Background technique
Table tennis (table tennis), Chinese national ball game are a kind of ball sports project of world pop, industry history
It is long;Currently, as the improvement of people's living standards, people when choosing table tennis, especially professional team, to table tennis
Quality requirement it is also higher and higher, it is uneven by the sphere weight of table tennis, and caused by table tennis degree of eccentricity difference be table tennis
Total quality is good with bad important indicator, however in the prior art for the degree of eccentricity measuring technology of table tennis relative to not at
It is ripe, and the test of degree of eccentricity this respect is even ignored by part producing manufacturer, the table tennis quality for causing market to be sold is not guaranteed,
Often have product of inferior quality appearance.The distribution of weight of ping-pong racket body uniformly whether directly affect the use of pang pang ball, i.e., it is eccentric
The abnormal motion of offset track can be generated by spending biggish table tennis;Manually table tennis is carried out using test, not only error it is big,
Test result is simultaneously unreliable, and test large labor intensity, test time-consuming, in consideration of it, Publication No. CN106568360A
Chinese patent, it discloses a kind of table tennis degree of eccentricity tester, it includes organic block, base is equipped with transmitting guide groove, hair
The top that guide groove is located in front of base is penetrated, glass support plate is additionally provided on base, glass support plate is equipped with glass, and glass is separate
The side and base for emitting guide groove are equipped with gap, guide groove group are equipped with below glass support plate, before guide groove group is connected to base
Both ends afterwards, the outside in front of base are equipped with sample box;The table tennis degree of eccentricity tester first, to serve a ball manually, non-automated,
When in face of the detection demand of large batch of table tennis, under detection efficiency seems very low;Secondly tester, because of its structure
Limitation, service power-assisted only lean on one section of slope and generate the rolling force of table tennis, and rolling force is insufficient, the quality unevenness situation of table tennis
It can not be reflected well, lead to the detection effect of table tennis and bad.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of table tennis bias inspection
The ball serving device of survey.
In order to solve the above technical problems, the technical solution that the utility model is taken is as follows:
