Front end traction device of output platform of bag making machine

Abstract

The invention relates to a front end traction device of an output platform of a bag making machine. The front end traction device of the output platform of the bag making machine comprises a traction roller, a guide roller and a tensioning roller which are arranged between two opposite rack plates, wherein the traction roller is driven by a motor; supporting beams are respectively and fixedly connected onto the inner sides of the two rack plates, the traction roller is rotatably arranged between certain ends of the two supporting beams, one end of the traction roller is fixedly connected with a first bevel gear, the motor is arranged on the outer sides of the rack plates, the axial direction of a motor shaft is perpendicular to the axial direction of the traction roller, and a second bevel gear engaged with the first bevel gear is fixedly connected onto the motor shaft; the tensioning roller is arranged between the traction roller and the guide roller and tilts to the lower part of the rack plates relative to the guide roller; the tensioning roller is arranged in sliding grooves in the rack plates through adjusting rods. The front end traction device of the output platform of the bag making machine has the advantages that the structure is simple and the design is reasonable; by adopting a non-axially arranged motor driving structure, the axial size is reduced, the occupied space is reduced and the structure is compact; by arranging vertical adjusting rods and adjusting the tensioning force of the tensioning roller through adjusting sleeves, the front end traction device is simple and convenient to operate.

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 and export. Among them, the output after bag forming is a relatively critical process in the bag making machine. The existing output platform adopts a belt transmission structure, which has the disadvantages of inconvenient adjustment of the tension of ...

Problems solved by technology

Among them, the output after bag forming is a relatively critical process in the bag making machine. The existing output platform adopts a belt transmission structure, which has the disadvantages of inconvenient adjustment of the tension of the guide roller, large space occupied by the motor, and low transmission stability.
