Electrostatic film underseal bag making machine

Abstract

The invention relates to an electrostatic film underseal bag making machine which comprises a feed device, a tension device, a longitudinal sealing device and a bag cutting device. The machine is characterized in that an edge folding device is arranged between the feed device and the tension device; the edge folding device comprises a rack, an edge folding triangular rack, clamping rollers, a guide roller, a guide-in roller and a guide-out roller; the edge folding triangular rack is obliquely installed on the rack in an inverted triangular shape, and is an equilateral triangle, the vertex angle alpha of the edge folding triangular rack is 55-65 degrees, and the included angle beta between the edge folding triangular rack and the bottom of the rack is 40-70 degrees; and the guide-in roller is installed on the rack above the edge folding triangular rack, the two clamping rollers are installed on the rack below the edge folding triangular rack, the guide roller is installed at the lower sides of the two clamping rollers, and the guide-out roller is installed on the left of the guide roller. The machine provided by the invention has the advantages that two folding edges of a folded packing bag film are parallel and neat, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a bag-making machine, in particular to an electrostatic film bottom-sealed bag-making machine. Background technique [0002] With the continuous improvement of people's living standards, packaging bags have become an indispensable packaging product in people's lives; the electrostatic film bottom sealing bag making machine is used to produce bottom sealing packaging bags, which includes feeding devices, tension devices, longitudinal sealing devices and Bag cutting device, because the production of bottom-sealed packaging bags is to fold the packaging bag film in half and then seal it vertically, while the current packaging bag film is folded in half manually and then put into the electrostatic film bottom-sealed bag making machine for bag making For this reason, when manually folding in half, the two pairs of folded edges of the packaging bag film are prone to non-parallel and neat situations in the half-folding of the packa...

[0002] With the continuous improvement of people's living standards, packaging bags have become an indispensable packaging product in people's lives; the electrostatic film bottom sealing bag making machine is used to produce bottom sealing packaging bags, which includes feeding devices, tension devices, longitudinal sealing devices and Bag cutting device, because the production of bottom-sealed packaging bags is to fold the packaging bag film in half and then seal it vertically, while the current packaging bag film is folded in half manually and then put into the electrostatic film bottom-sealed bag making machine for bag making For this reason, when manual folding is carried out, the two pairs of folded edges of the packaging bag film are prone to non-parallel and neat situations after the half-folding of the packaging bag film, which affects the production quality of the bottom-sealed packaging bag, and its production efficiency is low.
