1. A method for manufacturing a golf ball having a multi-layered pattern, comprising the following steps:
(a) providing a semi-finished product of the golf ball, wherein the semi-finished product of the golf ball includes a ball-shaped body and a base layer covering an outer surface of the ball-shaped body; and
(b) rotating the semi-finished product of the golf ball at a predetermined rotation speed, and applying a color paint to the semi-finished product of the golf ball from each of an upper position, a middle position, and a lower position by spraying, so as to form the multi-layered pattern on the base layer, wherein a first sprayer is used to apply the corresponding color paint from the upper position, a second sprayer is used to apply the corresponding color paint from the lower position, and a third sprayer is used to apply the corresponding color paint from the middle position;
performing a self-cleaning process of each of the first sprayer, the second sprayer, and the third sprayer after steps (a) and (b) are repeated for n times, where n is a positive integer;
wherein the multi-layered pattern includes an upper-layer pattern area, a mid-layer pattern area, and a lower-layer pattern area that are different in color from each other;
wherein each of the first sprayer, the second sprayer, and the third sprayer is fixedly connected to a support by a position adjusting mechanism that includes a sliding member, a supporting arm, and an angle adjusting assembly, the sliding member is slidably disposed on the support, the supporting arm is fixedly connected to the sliding member, and the angle adjusting assembly is installed at one end of the supporting arm for fixing the first, second or third sprayer and adjusting its angle relative to the horizontal reference plane;
wherein the angle adjusting assembly includes a pivot, an adjusting rod, a fixing seat, and a dial indicator, the pivot is fixedly connected to the one end of the supporting arm, the adjusting rod is pivoted on the pivot, the fixing seat is integrated with the adjusting rod, and the dial indicator is disposed at one side of the fixing seat.
