Description

Technical Field

[0001] The utility model relates to the technical field of distributor welding, in particular to an automatic conveying device for printing external markings of a distribution box. Background Art

[0002] In the power system, distribution boxes, metering boxes, etc. are key equipment for power distribution, protection and control. The printing quality of their logos is directly related to the safety and reliability of the power system. In the traditional printing process of external logos of distribution boxes, the transportation and lane change of materials often rely on manual operation, which not only increases the labor intensity of workers, but also easily leads to unstable printing quality due to human factors. Specifically, in the traditional printing process of external logos of distribution boxes, the transportation of materials (such as the outer shell of the distribution box) is usually completed by a single conveyor belt. When the material needs to be transferred from the loading area to the unloading area for printing, the worker needs to manually remove the material from the conveyor belt and place it on another conveyor belt, or transfer the material to the printing equipment by other means. This operation mode is not only inefficient, but also easy to cause damage or contamination during the material transfer process, affecting the final printing quality. In addition, due to the uncontrollability of manual operation, the material may be offset, misaligned, etc. during the transportation and lane change process, resulting in inaccurate printing position, and even need to be reprinted, increasing production costs and time costs. Therefore, developing a device that can automatically complete the material transportation and lane changing of the printed markings outside the distribution box is of great significance for improving production efficiency, reducing labor intensity, and ensuring printing quality.
