Description

Technical Field

[0001] The utility model relates to a reciprocating machine for three-dimensional five-sided spraying, belonging to the technical field of container spraying. Background Art

[0002] Container spraying is also one of the important processes in container processing. The sprayed container is not only beautiful in appearance but also has functions such as anti-corrosion. The original container spraying was carried out manually, which not only wasted a large amount of manpower and material resources, but also, due to the limitation of the working level of spraying personnel, the phenomenon of uneven spraying might occur, and at the same time, it was harmful to the health of spraying workers.

[0003] Therefore, many manufacturers have carried out research and development on container spraying equipment. The disadvantages of existing equipment are as follows: 1. Some equipment has too many nozzles. After walking once, the whole carriage is in a full coating state and cannot spray a specific area separately; 2. Some equipment has too few nozzles. The reciprocating movement of the nozzles is realized through a separate moving arm, which not only has low working efficiency but also has a high equipment failure rate; 3. The nozzle directions of most equipment are fixed and cannot be adjusted, so they can only spray the corresponding spraying surfaces of the container and cannot spray the front and rear doors of the container separately.
