A ball game surface spraying device with a limiting structure

Abstract

The application provides a ball toy surface spraying device with a limiting structure and relates to the technical field of robot spraying. The application discloses a ball toy surface spraying device with a limiting structure and relates to the technical field of robot spraying. The ball toy surface spraying device with the limiting structure comprises a movable part, which is used for positioning the position, which does not need to be sprayed, downward in advance. Meanwhile, the position of the movable plate on the bottom rod is changed by rotating an adjusting screw, and then the activity range of the swing part in the assembling groove is adjusted. When spraying, the swing part drives the spherical toy to rotate and swing according to a limited angle, so that the spherical toy is only partially exposed to the nozzle, and thus the accurate spraying of the specific area of the spherical body is realized. In this way, the diversified design requirements of local pattern forming and functional area division can be met. The existing spraying process can only realize the full-coverage spraying of the whole outer surface of the toy ball and cannot accurately limit the spraying area according to the production requirements (such as local pattern forming, specific functional area division and the like). Therefore, the diversified product design requirements cannot be met, and the problem of paint waste and increased production cost caused by unnecessary spraying may occur.

Description

TECHNICAL FIELD

In the production and processing process of ball toys, spraying processing is one of the key processes, which is usually implemented after the toy ball body is formed, mainly through a spraying robot to execute a specific automated spraying process to form a uniform coating on the surface of the ball, which not only gives the ball toy rich colors and patterns, enhances its visual appeal, but also plays a protective role in wear resistance, slip resistance, color fading resistance, and antibacterial properties, prolonging the service life of the toy and enhancing safety.

[0003] However, the current production process in the field of ball toy spraying processing still has obvious defects, which restricts the improvement of product quality and production adaptability, and the specific problems are as follows:
