AI Technical Summary

Technical Problem

Existing packaging production lines have dust residue problems. Traditional manual cleaning is inefficient and easily contaminates products. Fixed air gun cleaning is energy-intensive and indiscriminate cleaning can easily damage the packaging. In addition, the lack of packaging position sensing capability results in insufficient cleaning coverage.

Method used

Compressed air is buffered by an air tank, and pulse valves and manual ball valves are used to achieve on-demand spraying. The packaging position is detected by a photoelectric switch and the pulse valve is triggered to open, which works in conjunction with the nozzle array on the blow pipe to remove dust in a targeted manner.

Benefits of technology

It achieved energy conservation and consumption reduction, improved dust removal efficiency, reduced production line transformation costs, and ensured the safety and cleanliness of packaging.

Abstract

This utility model discloses a conveyor belt packaging purging device, including an air tank, a pulse valve, a photoelectric switch, a purging pipeline, and a manual ball valve. The air tank is fixed to the side of the conveyor belt frame, and its outlet is connected to the pulse valve and the manual ball valve in sequence via flanges. The purging pipeline consists of two parallel annular sections mounted above the conveyor belt inlet, allowing for purging of both the top and bottom surfaces of the packaging. Its inlet end is connected to the outlet of the manual ball valve, and a directional, inclined nozzle array is welded to the bottom of the pipeline. The photoelectric switch is mounted 1m upstream of the starting end of the purging pipeline via an adjustable bracket, and its signal line is connected to the control end of the pulse valve. This utility model uses the air tank to stabilize and store compressed air, and in conjunction with the instantaneous opening of the pulse valve triggered by the photoelectric switch, ensures that the airflow is directionally sprayed only when the packaging passes through. This working mode reduces air consumption to one-third of that used for continuous purging, improving energy efficiency and avoiding interference from ineffective airflow on the conveyor belt environment.
