Triangle bag forming and cutting mechanism

The utility model discloses a forming and cutting mechanism of a triangular plastic packaging bag, which is suitable for the packaging of grains, powders and liquid products such as foods, beverages and condiments. It includes worktables, programmable controllers, solenoid valves, air compressors and cylinders. The cylinders are fixed on the worktable. Programmable controllers and air compressors are connected to the solenoid valves through wires, and the air cylinders pass through the air tubes. Connect with solenoid valve set. The cylinders are two pairs of cylinders that are disposed opposite to each other. A heat seal block is fixed to the end of the piston rod of each cylinder, and each heat seal block is perpendicular to the piston rod of the cylinder to which it is connected. There is also a push-knife cylinder below each cylinder in each pair of cylinders. The cutting knife is fixed at the end of the piston rod of each push knife cylinder. This triangular bag forming and cutting mechanism not only produces beautiful packaging bags, satisfies packaging requirements for different articles, but also can increase production efficiency and reduce the operator's labor intensity.
