AI Technical Summary
Existing flattening devices push air out of the biodegradable plastic bags in a disorderly manner, affecting the efficiency of air expulsion and flattening, and it is difficult to avoid the plastic bags breaking at the seams.
The system employs a pre-pressing and flattening mechanism and an auxiliary heating mechanism. It utilizes the raised parts of the pressure roller to collect air, and combines elastic pressure and negative pressure adsorption to ensure that the air is smoothly discharged and to maintain the flatness of the plastic bag.
It improves exhaust efficiency, prevents plastic bags from breaking, and ensures the flatness of the plastic bags and production efficiency.
