The invention relates to film producing and processing equipment, in particular to a two-way synchronous film stretching processing device which comprises a horizontally-arranged bottom plate, the two sides of a lower guide roller are symmetrically sleeved with movable shaft sleeves in a sliding mode, and matching wheels are coaxially fixed to the movable shaft sleeves; an upper pressing assembly and a lower pressing assembly are arranged above the two sets of upper guide rollers and below the two sets of lower guide rollers correspondingly and connected through a reverse moving structure. The driving assembly is connected with the upper pressing assembly and further connected with the longitudinal pulling mechanism. The upper pressing assembly is connected with the transverse pulling mechanism through the transmission assembly, and the transverse pulling mechanism is connected with the lower pressing assembly. The driving assembly drives the upper pressing assembly to move downwards, the upper pressing assembly drives the lower pressing assembly to move upwards through the reverse moving structure, and a film is fastened between the upper guide roller and the lower guide roller. Then the driving assembly drives the longitudinal stretching mechanism to move downwards continuously, and the previous section of film is stretched longitudinally; the transmission assembly drives the transverse stretching mechanism to transversely stretch the next section of film, so that the two-way stretching effect is achieved.
Description
technical field [0001] The invention relates to a film production and processing equipment, in particular to a film bidirectional synchronous stretching processing device. Background technique [0002] The film will be oriented in the process of processing, which is generally divided into horizontal and vertical directions. Due to different processing techniques and parameters, the orientation is also different. For example, blown film has both longitudinal traction and transverse inflation, which is relatively balanced relative to the longitudinal and transverse orientations, and the mechanical properties in both directions are relatively balanced. For casting, there is only longitudinal traction, but no transverse inflation. Therefore, the longitudinal orientation is greater than the transverse direction, and the mechanical properties in the two directions are significantly different. For example, the longitudinal tensile force is large, but the tear strength is very low. ...
