Abstract

The invention discloses a thermoplastic film traction machine which comprises a traction track and a conveyor belt, wherein the traction track is positioned below the conveyor belt and is parallel to the conveying direction of the conveyor belt; the conveyor belt is connected with a motor driving the belt to operate; sliding strips are fixedly connected to two sides of the traction track; the traction machine further comprises a fixation device used for fixing a thermoplastic film on the traction track; the fixation device comprises a positive pressing plate and side pressing plates hinged with two ends of the positive pressing plate; the positive pressing plate is connected onto the conveyor belt; the length direction of the positive pressing plate is perpendicular to the conveying direction of the conveyor belt; stoppers are connected inside the side pressing plates; grooves in clearance fit with the sliding strips are formed in the stoppers; springs are connected in the grooves; and baffles are connected to free ends of the springs. A pressure is produced to the baffle through the spring during thermoplastic film traction, so that the thermoplastic film is fixed between the baffle and the sliding strip and is automatically released when reaching a turn, and deformation of the thermoplastic film is avoided.

Description

technical field [0001] The invention relates to a pulling device, in particular to a thermoplastic film pulling machine. Background technique [0002] Thermoplastic film, referred to as thermoplastic film, is a film made of thermoplastic resin as the base material. Such as polyethylene film, polypropylene film, polyvinyl chloride film, polystyrene film, polycool film, polyamide film, etc. Its properties and uses vary with varieties. The largest amount of polyethylene film and polyvinyl chloride film is mainly used in packaging industry and agriculture; polycool film and polyamide film are mainly used as insulating materials and packaging materials. The production methods are mostly extrusion blow molding and calendering, extrusion stretching and casting. [0003] When making thermoplastic film by extrusion stretching method, it is necessary to use a traction device for thermoplastic film. The current traction device includes a traction track and a transmission belt. The t...
