小改造治顽疾

Core Viewpoint - The recent technical transformation at Lu'an Hengtong Chemical's resin plant effectively addressed the dust adsorption issue of PVC packaging bags, enhancing the long-term safe and stable operation of the facility [1] Group 1: Problem Identification - The surface of finished PVC packaging bags is prone to dust adsorption, leading to challenges during the stacking process, including the risk of bags slipping and collapsing [1] - Previous methods to handle dust involved using compressed air for cleaning, which resulted in significant waste of air resources [1] Group 2: Solution Implementation - A task force was organized to focus on solving the dust problem, collecting first-hand data on packaging machine parameters, PVC material transfer speeds, and dust adsorption patterns [1] - The task force established a four-step modification method aimed at "precise control and source dust reduction" [1] - The first step involved upgrading the dust removal system to enhance the vacuum level of the PVC packaging system, thereby reducing dust emissions at the source [1] - The second step included recalibrating the gripping force of the packaging bag clamps and aligning the bag openings to prevent dust leakage during material loading [1] - The third step required fine-tuning the installation height of the packaging sewing machine and hot melt adhesive tape to ensure a tight seal, blocking dust escape routes [1] - The fourth step focused on optimizing the exhaust holes of the packaging bags to ensure smooth air discharge while preventing dust from escaping with the air [1] Group 3: Results and Impact - Following the modifications, the dust issue on-site showed improvement, reducing the waste of air resources previously caused by compressed air cleaning [1] - The initiative fostered a culture of continuous improvement among employees, embedding the spirit of lean innovation within the workforce [1]
