The invention relates to a film production and processing equipment, in particular to a film bidirectional synchronous stretching processing device, which comprises a horizontally arranged bottom plate, a movable shaft sleeve is slid symmetrically on both sides of a lower guide roller, and a movable shaft sleeve is coaxially fixed on the movable shaft sleeve. Matching wheel; the upper and lower guide rollers are respectively provided with an upper pressing component and a lower pressing component, and the upper pressing component and the lower pressing component are connected by a reverse moving structure; the driving component is connected to the upper pressing component, and drives the The assembly is also connected with a longitudinal pulling mechanism; the upper pressing assembly is connected with the horizontal pulling mechanism through the transmission assembly, and the horizontal pulling mechanism is connected with the lower pressing assembly. The upper pressing component is driven to move down by the driving component, and the upper pressing component drives the lower pressing component to move upward by means of the reverse moving structure, so that the film is fastened between the upper guide roller and the lower guide roller; then the driving component drives the longitudinal pulling mechanism to continue to move down , stretches the former film longitudinally; the transmission component drives the transverse stretching mechanism to stretch the latter film transversely, so as to achieve the bidirectional stretching effect.
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. ...
