Description

TECHNICAL FIELD

[0001] The utility model relates to container production technical field, concretely is a kind of paint spraying equipment for container production. BACKGROUND

[0002] Container transportation is an important transportation mode in the process of multimodal transport of international trade goods. Due to the advantages of container transportation, such as high standardization, good sealing, low damage rate, intensification, large scale, linerization, low cost, good quality and the like, the safety and efficiency of goods transportation are greatly improved. In the production process of the container, a layer of paint is often sprayed on the outside of the container to improve the rust-proof performance of the container and make it more durable.

[0003] The existing paint spraying equipment for container production lacks a hanging component, which cannot spray the bottom of the container when it is placed on the ground. Some simple hoisting methods can spray the bottom, but cannot well spray the top of the container, and workers need to hold a spray gun to move back and forth, which is inconvenient to use and has low spraying efficiency. Therefore, we propose a paint spraying equipment for container production. UTILITY MODEL CONTENTS
