Double-output middle sealing full-automatic bag-making apparatus and bag-making method thereof

Abstract

The invention relates to a double-output middle sealing full-automatic bag-making apparatus that is capable of utilizing a doubly-printed spiral membrane as a raw material, simultaneously producing two membrane bags every time, effectively improving the production efficiency and saving energy sources. The double-output middle sealing full-automatic bag-making apparatus comprises a feeding device 1, a folding device 2, a hot sealing device 3 and a discharging device 4, all of which are connected orderly from front to back; the double-output middle sealing full-automatic bag-making apparatus is characterized in that the feeding device 1 comprises a back folding device 1.1 that includes a first baffle plate 1.1.1, a second baffle plate 1.1.2, a third baffle plate 1.1.3, a fourth baffle plate 1.1.4 and a fifth baffle plate 1.1.5, and the first baffle plate 1.1.1, the second baffle plate 1.1.2, the third baffle plate 1.1.3, the fourth baffle plate 1.1.4 and the fifth baffle plate 1.1.5 are arranged up and down alternately; the folding device 2 comprises a folding device body 2.1, a cutter 2.2, a clamping roller 2.3 and a plurality of folding plates 2.4, and the cutter 2.2, the clamping roller 2.3 and the plurality of folding plates 2.4 are mounted on the folding device body 2.1.

Description

Technical field [0001] The invention relates to a bag-making machine, in particular to a double-out middle-sealing automatic bag-making device and a bag-making method thereof. Background technique [0002] With the continuous improvement of people's quality of life, the requirements for the shape of daily necessities and food packaging bags are getting higher and higher. At present, the bag bodies with various characteristics and beautiful appearance are favored by customers, and there is an urgent need for bag making machines that can meet this demand. Merchants have seized this business opportunity, which has led to the emergence of large quantities of bag making machines on the market in recent years. [0003] Such as figure 1 As shown, the back-folding devices of the prior art middle-sealing automatic bag making machine are all three baffles 0.1, and the single-print roll film is back-folded in the back-folding device, and the back-folded is both sides of the single-printing fi...
