Description

Technical Field

[0001] This utility model relates to a packaging machine, and more specifically, to a bag replenishment device for a multi-row packaging machine production line in the post-processing machinery of strip-packaged food or pharmaceutical packaging machinery production equipment. Background Technology

[0002] In the post-packaging processing of machinery, modern production is becoming increasingly automated and intelligent. From material feeding and packaging to subsequent processing, weighing, inspection, rejection, conveying, sorting, counting, and final boxing, fully automated production lines require high-speed, stable, and accurate operation. Traditional processing often involves weighing small bags produced by multiple rows of machines one by one. When a defective product is found, the entire row is rejected, resulting in significant waste. Therefore, there is a need for single-row inspection and rejection. The subsequent processing must address the replenishment of rejected materials in counting and conveying stages. Traditional manual replenishment significantly reduces the automation and intelligence of the entire production line. Furthermore, this issue must be addressed urgently for manufacturing enterprises with high hygiene requirements. Utility Model Content
