[0027] See also Figure 1-5 The rotating mechanism for the coating surface production line shown includes a carrier plate 1, both ends of which are provided with mounting holes, a limit rotation hole 15 is provided on the carrier plate 1, a rotating shaft 14 is rotatably provided in the limit rotation hole 15, the upper end of the rotating shaft 14 is fixedly connected to a support plate 2, and a plurality of limit blocks 3 are provided on the upper surface of the support plate 2 in a rectangular shape, a first gear 12 is sleeved on the bottom of the rotating shaft 14, the first gear 12 is meshed with a second gear 13, the second gear 13 is sleeved on the rotating shaft 14 of the motor 11 arranged below the carrier plate 1, and the radius of the first gear 12 is greater than the radius of the second gear 13.

[0028] Through the implementation of the above technical solution, when in use, the shell workpiece that needs to be sprayed and coated is first turned upside down on the support plate 2, and the horizontal position of the shell workpiece is limited by multiple limit blocks 3. During the spraying process, the motor 11 rotates to drive the first gear 12 and the second gear 13 to rotate, thereby driving the support plate 2 to rotate, so that multiple surfaces of the workpiece are sprayed in turn, thereby improving the spraying efficiency. In order to further improve the spraying effect, the radius of the first gear 12 is set to be larger than the radius of the second gear 13, so that the rotation speed of the first gear 12 is less than the second gear 13, thereby slowing down the rotation speed of the support plate 2, so that each surface of the workpiece has sufficient spraying time, thereby improving the spraying effect.

[0029] In this embodiment, in order to further provide a method for installing the motor 11 , a frame is provided below the supporting plate 1 , and the motor 11 is installed on the frame.

[0030] In this embodiment, in order to further provide a frame structure, the frame includes a plate body 9 disposed below the second gear 13; the plate body 9 is connected to the carrier plate 1 through a plurality of columns 10. The plurality of columns 10 are distributed in a matrix to avoid the first gear 12 and the second gear 13.

[0031] In this embodiment, in order to further provide a limited rotation structure of the rotating shaft 14, an annular groove 16 is provided in the limited rotation hole 15; and a limiting ring 17 is provided outside the rotating shaft 14 and rotates in the annular groove 16. When the rotating shaft 14 rotates, the limiting ring 17 rotates in the annular groove 16, so that the rotating shaft 14 can achieve the function of limiting the vertical direction while rotating.

[0032] In this embodiment, a right-angle notch 8 is provided at the bottom side of one end of the carrier plate 1. Since the support plate 2 is not installed at the center of the carrier plate 1, in order to cooperate with the spraying of the spraying device on the spraying production line, the right-angle notch 8 is provided for foolproof alignment, so that the carrier plate 1 can be accurately assembled in place.

[0033] In this embodiment, the bottom sides of both ends of the carrier plate 1 are installed with connecting plates 7 through bolts 5; the bolts 5 are arranged through the installation holes, and a convex plate 6 that matches the right-angle notch 8 is arranged on the upper side of one of the connecting plates 7. The convex plate 6 and the right-angle notch 8 are matched to prevent fooling, and the installed connecting plate 7 is used to connect with the conveying equipment on the spraying production line, such as a chain plate conveyor. By fixing the connecting plate 7 on the chain plates on both sides of the chain plate conveyor, the horizontal conveying of the carrier plate 1 is realized, and the workpiece can be switched between the spraying station and other stations through the reciprocating transportation of the chain plate conveyor. For example, the workpiece to be sprayed is loaded at an idle position, and then moved to the spraying station for spraying. After the spraying is completed, it is moved to the unloading station for unloading, and finally reset to the idle station to repeat the above work.

[0034] In this embodiment, a multi-step step groove 4 is arranged on the outer side of the limit block 3. Through such arrangement, the limit block 3 can be used to perform inverted limit on shell workpieces of different specifications, the bottom surface of each layer of the step groove 4 is flush, and the shape formed by the outer side surface of each layer of the step groove 4 corresponds to the inner wall of the shell workpiece to achieve horizontal limit.

For example, the step groove 4 is in the shape of an arc, and the limit blocks 3 are arranged in a matrix with four, and the multiple arc-shaped step grooves 4 of each layer are surrounded to form a circular contour. For another example, the step groove 4 is in the shape of a right angle, and the limit blocks 3 are arranged in a matrix with four, and the multiple right-angled step grooves 4 of each layer are surrounded to form a rectangular contour.
