AI Technical Summary

Technical Problem

Existing dust removal equipment for woven bags before printing suffers from low dust removal efficiency and incomplete cleaning, which affects printing quality.

Method used

Using a negative pressure dust collection method, a conveying mechanism consisting of a negative pressure pipe and a rotating sleeve, combined with a negative pressure pump, generates negative pressure suction to clean the dust and debris on the surface of the woven bag. The serpentine winding ensures that both sides are clean. Dust enters the dust filter and is blocked into the dust collection tank.

Benefits of technology

It effectively improves the cleaning effect of woven bags, ensures printing quality, avoids problems such as blurry printing, color difference and missing printing, and improves the appearance and recognition of products.
