Support structure in extrusion line

Abstract

The invention relates to the field of extrusion technology, and discloses a supporting structure in an extrusion production line, including an upper template, a mandrel is arranged on the inner side of the upper template, a connecting mechanism is arranged on the inner side of the mandrel, and the lower end of the connecting mechanism A connecting rod is provided, the lower end of the connecting rod is provided with a No. 1 fixing mechanism, the lower end of the No. 1 fixing mechanism is provided with a steel wire rope, and the lower end of the steel wire rope is provided with a No. 2 fixing mechanism. There is an inner support body, and the inner support body includes a support frame, a sliding mechanism, and a connecting block. The inner support structure of the extrusion production line can connect the inner support body with the mandrel through a steel wire rope. , and can support the extruded product to avoid deformation of the extruded product during stretching.

Description

technical field [0001] The invention relates to the technical field of extrusion, in particular to a support structure in an extrusion production line. Background technique [0002] Stretch blow molding process refers to a blow molding process through biaxial directional stretching. Stretch blow molding process is developed on the basis of ordinary extrusion blow molding process and injection blow molding process. The parison is made by the extrusion method or the injection method, and then the parison is processed to a suitable stretching temperature for the plastic, and it is longitudinally stretched by internal (with stretching mandrel) or external (with stretching fixture) mechanical force, at the same time or Later, it is stretched transversely by compressed air inflation, and finally the product is obtained. The stretching is to improve the physical and mechanical properties of the plastic. For amorphous thermoplastics, stretching is carried out in the range of thermoe...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a support structure in the extrusion production line, which is relatively convenient to install, and the connection is relatively firm, not easy to break, the service life is long, and the disassembly is relatively convenient. It can not only stretch the extruded product, Moreover, it can support the extruded product, avoid the deformation of the extruded product during the stretching process, etc., and solve the serious deformation of the product during the stretching process, and the stretching device is welded on the mandrel, which cannot be disassembled and supported. The problem of inconvenient installation of the structure
