Full-automatic folding and strapping machine for plastic bags

Abstract

The invention discloses a full-automatic folding and strapping machine for plastic bags. The full-automatic folding and strapping machine for the plastic bags structurally comprises a cross beam, supporting stand rods, two or more U-shaped handles, a drive transmission device, a base, a rotary shaft barrel, a top plate, a rotary shaft core and a drive controller, wherein the supporting stand rodsare perpendicularly welded to the left side and the right side of the upper portion of the drive transmission device; the base is nested on the outer side of the drive transmission device in an interference fit mode; the two ends of the cross beam are perpendicularly welded to the upper portions of the supporting stand rods; the two ends of an opening of each U-shaped handle are perpendicularly welded to the left end and the right end of the upper portion of the drive transmission device separately; the rotary shaft barrel is installed above the middle of the right side of the drive transmission device in a clearance fit mode; the rotary shaft core is of a circular structure and is installed in the middle of the right side of the top plate in an interference fit mode; and the drive controller is installed in the middle of the front end of the supporting stand rod on the right side in an interference fit mode. In the using process, the degree of strapping tightness of the machine can beimproved, the strapping speed of the machine can also be adjusted, and the using efficiency is high.

Description

technical field [0001] The invention is an automatic folding and binding machine for plastic bags, which belongs to the field of folding and binding machines. Background technique [0002] The existing plastic bag folding and strapping machine, in the process of processing the tubular plastic film into a finished bag and packaging it, only realizes preliminary automation in the steps of printing, bag making, and handle cutting. The bag making machine for plastic bags is divided into single-line machine and double-line machine. The single-line bag-making machine only puts one plastic film roll and only processes one plastic bag at a time. The double-line bag-making machine can put two plastic film rolls on the left and right at the same time. Two plastic bags can be processed at the same time. The plastic bags produced on the bag making machine can be automatically stacked one by one on the plastic bag pallet. The single-line bag making machine only stacks one stack, and the ...
