Packaging machine for filling by double-bag

Abstract

The invention relates to a packaging machine and belongs to a packaging machine for simultaneously filing by double bags. The invention mainly improves a bag opening flattening mechanism, a trolley and an action mechanism of the trolley, a swinging rod and a driving mechanism of the swinging rod; the trolley and the action mechanism thereof consists of the trolley, a closing mechanism and a driving connection rod; the driving mechanism of the swinging rod is in drive connection with the swinging rod; the bag opening flattening mechanism consists of a right connection rod, a right bag opening flattening head, a left connection rod and a left bag opening flattening head; three rotating shafts are arranged at the front end of the swinging rod; the rotating shaft C is movably connected with the left connection rod, the other end of the left connection rod is movably connected with the tail end of the bag opening flattening head; the rotating shaft A is movably connected with one end of the driving connection rod of the trolley, the other end of the driving connection rod of the trolley is movably connected with the trolley; the rotating shaft B is movably connected with the right connection rod, the other end of the right connection rod is movably connected with the tail end of the bag opening flattening head. Based on the existing packaging machine, the packaging machine in the invention can simultaneously flatten the double bag openings by adding the connection rod on the top end of the swinging rod through the cooperation of the three mechanisms, so that the two packaging bags can simultaneously finish the filling process, only little cost is increased and the efficiency of the packaging machine is doubly improved.

Description

technical field [0001] The invention relates to a packaging machine. Background technique [0002] In the prior art, the working steps of the fully automatic packaging machine are as follows: in the first step, the plastic wide band is folded in half to form a double-layer belt with an upward opening; in the second step, the folded double-layer plastic belt is passed through a high-frequency heat press machine Press out two traces to form a conjoined bag; step 3, cut off the plastic bag on both sides of the hot-pressing trace; step 4, suck open the upward opening of the bag; step 5, fill the bag with Pack food; step 6, flatten the bag; step 7, high-frequency heat sealing; the whole process is as follows figure 1 shown. Since this kind of packaging machine is a single package, the disadvantage is that the efficiency is low. [0003] The above-mentioned existing packaging machinery comprises a trolley and its operating mechanism 1, a swing rod and its driving mechanism 2, a...
