The invention relates to an upper cutter device of a bag making machine, which includes an upper cutter frame for installing the upper cutter and an upper cutter pushing device for driving the upper cutter to move up and down; the structure of the upper cutter frame is as follows: The lifting cross bar of the cutting knife on the device, the two ends of the lifting cross bar are slidingly installed on the two opposite rack plates; the two ends of the lifting cross bar are respectively slidingly installed in the U-shaped groove on the top of the rack plate by means of external bearings, The two ends of the lifting cross bar are respectively equipped with inner bearings, and the inner bearings are located on the inner side of the outer bearing; the brake device is installed on the frame plate; the elastic guide structure is installed on the frame plate at one end of the lifting cross bar; The device includes a mutually hinged push rod and a push connecting plate, and the push rod is driven by a push source; the upper cutter push device also includes an auxiliary cylinder, and the cylinder body of the auxiliary cylinder is hinged on the frame by means of a support, and the end of the piston rod is connected to the frame. Triangle hinged. The invention has simple structure, reasonable design and compact 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 plastic, paper and other materials. The process of forming the packaging bag by the high-speed bag making machine is: the upper film and the lower film are respectively guided and transported, and the upper and lower films are overlapped at the appropriate positions. The overlapped film is heat-sealed longitudinally and transversely to form an integrated structure of multiple small bags, and finally divided Cut into multiple pouches. Among them, the slitting process generally includes two processes of front cross cutting and post slitting. Post slitting is the process of separating the front and rear pouches from the film, which is completed by the post slitting mechanism. Th...
