Packaging bag extrusion device for automatic compound fertilizer bagging system

Abstract

The utility model relates to a packaging bag extrusion device for an automatic compound fertilizer bagging system. Comprising a bag conveying trolley, a bag clamping system for compound fertilizer packaging bags is arranged on the upper portion of the bag conveying trolley, bag clamping devices used for clamping the middles of the compound fertilizer packaging bags are arranged on the two sides of the lower middle portion of the bag clamping system, and clamping plate devices used for clamping bag openings of the compound fertilizer packaging bags are arranged on the two sides of the upper middle portion of the bag clamping system. The outer sides of the clamping plate devices on the two sides are each provided with an extrusion part used for clamping the upper middle portion of a compound fertilizer packaging bag, each extrusion part at least comprises two connecting supports, and the upper portions of the two connecting supports are each provided with a locking connecting piece connected with the corresponding clamping plate device. The bottoms of the two connecting supports are connected with extrusion round rods used for extruding the upper middle portion of the compound fertilizer packaging bag. The device has the characteristics of improving the heat sealing and bag sewing quality on the basis of not damaging the original equipment, and avoiding packaging bag bulging, compound fertilizer hardening and inconvenience in stacking and storage.
