Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an automatic pad printing device for a filter housing. Background Art

[0002] Filters play an important role in the automotive industry. They are devices used to filter out impurities that may cause damage to the car's engine and other systems.

[0003] Filters need to be labeled during production to ensure efficient sorting during inventory. Typically, the markings are printed on the filter housing. A common production method involves using a monochrome printer to print the housing on a conveyor belt.

[0004] However, during operation, operators discovered that the housing needed to be secured during printing. Although push rods and V-shaped plates were used to secure the housing, this required the cooperation of the guardrail on the conveyor belt. When the filter housing was not properly positioned on the conveyor belt, the push rod had to push a long distance. When the housing came into contact with the guardrail, it would exert a strong impact force on the guardrail. Over time, the guardrail and the conveyor belt could become loose, and this impact could also cause surface defects on the housing.

[0005] Therefore, a new automatic pad printing device is in urgent need of. Utility Model Content
