Spraying method of container mark

Abstract

The invention provides a spraying method of a container mark. The spraying method is used for spraying a mark on the outer surface of a container. The spraying method is characterized by comprising the following steps of (1) spraying a removable protective layer: spraying the removable protective layer in a preset mark spraying area in the outer surface of the container, wherein a nozzle is used for spraying from all contour lines of the mark to the external areas of the contour lines during spraying, and the removable protective layer with a hollow mark is formed in the mark spraying area after spraying is completed; (2) spraying paint: spraying special labeling paint to the internal areas of all of the contour lines after the removable protective layer is solidified; and (3) removing theremovable protective layer: removing the removable protective layer in the whole mark spraying area after the special labeling paint is solidified. The spraying method of the container mark has the advantages that automatic production can be realized, the mark spraying precision is high, the mark spraying quality is good, additionally, the process flow is simplified, the labor cost is low, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a container mark spraying method. Background technique [0002] Container refers to a large-scale loading container with certain strength, rigidity and specifications specially used for turnover. Using containers to transship goods can be directly loaded in the consignor's warehouse and unloaded in the consignee's warehouse. When changing vehicles or ships midway, there is no need to take out the goods from the box for repacking. In order to facilitate the development of container transportation and facilitate the international circulation of containers, containers are currently subject to standardized production management to improve the efficiency of containers in the transportation process. Therefore, each logistics company needs to spray signs or patterns for identification on containers. So as to distinguish it from the containers of other logistics companies. [0003] In the prior art, the method of manual operation is ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the method of manual operation is adopted for spraying labels on containers, such as figure 1 As shown, through the steps of cleaning, labeling paper, isolation protection, spraying labels, removing isolation protection devices, and trimming, since each step is manually completed, the construction period is long, and large errors may occur in each step

For example, in the step of labeling paper, the positioning of the labeling paper usually requires manual use of a ruler to draw the positioning dimension line, the positioning is not accurate enough, and it is easy to shift during the process of pasting; The film is used to cover the front of the container, and there is a window for spraying on the film. When protecting, the window needs to be aligned with the position of the spray mark, and the size of the window needs to be adjusted according to the size of the spray mark required, which is relatively cumbersome ;Furthermore, in the process of spraying labels in the prior art, due to the manual spraying method for spraying, it is impossible to ensure that the spray paint thickness of the signs is uniform, and certain color differences will be produced, which will affect the appearance.

In addition, in order to improve production efficiency in the production process, each process is carried out at different stations, which requires a relatively high space for production and processing, requiring a large production space

To sum up, it can be seen that the positioning accuracy of the labeling operation in the prior art is low. Since all manual operations are used, the production cycle is long and the production efficiency is low. Moreover, since operators are required for each process, the labor cost in the production process is relatively high. , and the qualified rate of spraying is low
