Problems solved by technology

[0002] At present, the general bag making machine adopts the cutting method. Since the polyethylene film of the heavy packaging bag processed is relatively thick (200-320um), the thickest film can reach 360um, and the bag film becomes soft after heating and sealing. , become sticky, therefore, the current cutting method is easy to cause the bag film to stick to the knife when cutting, resulting in uneven and jagged incision, which seriously affects the appearance of the product

Abstract

The invention relates to the technical field of packaging bag cutting devices, and particularly relates to a cutter mechanism for packaging bag films. The cutter mechanism comprises a left blade, a right blade, a movable cutter holder, a workbench, a swinging arm and an air cylinder, wherein the left blade and the right blade are respectively fixed to the movable cutter holder, the cutter edges ofthe left blade and the right blade respectively face outwards in opposite directions, the movable cutter holder is in sliding connection with the workbench, a hinged shaft is hinged to the bottom ofthe movable cutter holder, a chute is formed in the swinging arm, the hinged shaft is matched with the chute, the lower part of the swinging arm is hinged with a cross beam of the lower part of the workbench, the air cylinder is hinged to a side beam of the workbench by virtue of a cylinder seat, and a piston rod of the air cylinder is hinged with the middle of the swinging arm. According to the device, a bracket on which the two blades are installed is driven to do a reciprocating motion by the mechanical swinging arm, so that the packaging bag films are cut, and the cutter mechanism has theadvantages of simple structure, low cost, easiness in maintenance and good use effect for years.

Description

technical field [0001] The invention relates to the technical field of packaging bag cutting devices, in particular to a cutting knife mechanism for packaging bag film. Background technique [0002] At present, the general bag making machine adopts the cutting method. Since the polyethylene film of the heavy packaging bag processed is relatively thick (200-320um), the thickest film can reach 360um, and the bag film becomes soft after heating and sealing. , become sticky, therefore, the existing cutting method easily causes the bag film to stick to the knife when cutting, causing the incision to be uneven and jagged, which seriously affects the appearance of the product. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the above-mentioned technologies, and provide a cutting knife mechanism for packaging bag film, which does not stick to the knife when cutting, and the cut is neat. [0004] In order to achieve the abo...
