Abstract

The invention discloses a track mechanism of a synchronous two-way stretching machine with controllable chain clip track direction, which comprises a track, a chain clip system and a drive sprocket, the chain clip system is arranged in the track, and the drive sprocket is set at one end on the inside of the track. Compared with the prior art, the track mechanism of the synchronous bidirectional stretching machine with controllable track direction of the chain clip of the present invention can adjust the track of the chain clip mechanism through the shape change of the groove on the track to realize the change of the distance and speed between the film clips , the distance between the film clamps is small to large to realize the longitudinal stretching between the two film clamps, and at the same time, by changing the distance between the guide rails to adjust the position of the connecting shaft to drive the chain clamp to realize the transverse stretching of the film. The invention can simultaneously realize horizontal and vertical stretching of the film at a uniform speed, and solves the problems of uneven stretching thickness, uneven strength of various parts of the film and other unstable physical properties that may occur in the traditional process.

Description

technical field [0001] The invention relates to a track mechanism of a synchronous bidirectional stretching machine with controllable chain clip track direction. Background technique [0002] "Biaxial stretching" is one of the plastic film forming methods that have attracted much attention in recent years. The use of biaxial stretching technology can significantly improve the mechanical properties, barrier properties, optical properties, thermal properties and thickness uniformity of the film, which can meet various requirements. The production requirements of the application area. [0003] The basic principle of the plastic film biaxial stretching technology is: after the high polymer raw material is heated and melted by the extruder and extruded into a thick sheet, it passes When the stretching machine is under the action of external force, it is stretched to a certain multiple along the horizontal and vertical directions at the same time, so that the molecular chains or ...
