Problems solved by technology
The tensioning mechanism is a special mechanism for tensioning the film, facilitating its transportation, heat sealing and cutting. The traditional tensioning mechanism has a complicated structure, and it only relies on the tensioning device to tension the film. It is not easy to adjust after deviation, and it is inconvenient to adjust the tension

The invention relates to a tensioning force mechanism of a bag making machine. The mechanism comprises a fine adjustment conveying roller device and a tensioning device which are arranged between two opposite machine frame boards, the machine frame boards are arranged on a frame body composed of longitudinal beams, transverse beams and side beams, one diagonal line of a bottom rectangular structure composed of the longitudinal beams and the transverse beams is fixedly connected with a bottom oblique beam, and one diagonal line of a side face rectangular structure composed of one longitudinal beam and the corresponding side beams is fixedly connected with a side oblique beam. According to the tensioning force mechanism of the bag making machine, swing adjustment is conducted on a front guide roller set through adjusting rods so that fine adjustment of tensioning force of a thin film can be achieved, and the tensioning force mechanism is easy and convenient to operate and facilitates follow-up tensioning traction; all the components do not interfere with one another during movement, and work reliability is achieved; the thin film is tensioned by the adoption of an upper set and a lower set of guide roller and supporting plate structures rotating synchronously, limiting of the rotating angle between the thin film and a base and the rotating angle between the thin film and a rotary board is controlled through primary limiting and directional rotating of a limiting connecting rod, the tensioning force of the thin film is adjusted, rotating stability is improved, and the tensioning force change degree of the thin film is reduced.
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. The tensioning mechanism is a special mechanism for tensioning the film, facilitating its transportation, heat sealing and cutting. The traditional tensioning mechanism has a complicated structure, and it only relies on the tensioning device to tension...
