Abstract

The invention relates to a rear longitudinal cutting mechanism of a bag making machine. The rear longitudinal cutting mechanism comprises an upper cutter device and a lower cutter device. The upper cutter device comprises an upper cutter rest and an upper cutter push device for driving an upper cutter to do lifting motion. The upper cutter rest structurally comprises a lifting cross rod used for mounting the upper cutter, and the two ends of the lifting cross rod are arranged on two opposite rack plates in a sliding mode. Brake devices are arranged on the rack plates. An elastic guide structure is arranged on the rack plate at one end of the lifting cross rod. The upper cutter push device comprises a push rod and a push connecting plate, and further comprises an auxiliary air cylinder, and the auxiliary air cylinder is hinged to a rack. The lower cutter device comprises a lower cutter rest on the rack, and a lower cutter is fixedly connected to the lower cutter rest. The lower cutter rest is connected with a rack cross plate through symmetric screw rods. The screw rods respectively and rotatably penetrate through the rack cross plate, one end of each screw rod is in screw joint with the lower cutter rest, and the other end of each screw rod is axially and fixedly connected with a first bevel gear. The rear longitudinal cutting mechanism is simple in structure, reasonable in design and compact in structure.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a bag making machine. Background technique [0002] The bag making machine is a special equipment for making packaging bags, which is widely used in the production of packaging bags made of various plastics, paper and other materials. The process of forming a packaging bag by a high-speed bag making machine is: guiding the upper film and the lower film to be transported separately, overlapping the upper and lower films at a suitable position, and the overlapped films are heat-sealed longitudinally and transversely to form an integrated structure of multiple small bags, and finally separated. Cut into multiple pouches. Among them, the slitting process generally includes two processes of front cross cutting and rear slitting. The rear slitting is the process of separating the small bags arranged in front and rear from the film, and is completed by the rear slitting me...
