PET extrusion tool

Abstract

The invention discloses a PET extrusion tool. The PET extrusion tool comprises a bottom plate, installation strips, transverse pressing rollers, a longitudinal side rollers and interval adjusting mechanisms. According to the PET extrusion tool, transverse moving plates are subjected to left-right moving adjustment through abutting screws and driving screws in the interval adjusting mechanisms, byrotationally installing the abutting screws on positioning plates through threads, the inner ends of the abutting screws rotationally abut against the outer sides of the lower portions of the transverse moving plates, thus, the abutting screws can abut against the transverse moving plates to move towards the inner sides, then, by installing the driving screws on the positioning plates and the transverse moving plates in a penetrating connection mode, one ends of the driving screws are clamped to the inner side surfaces of the transverse moving plates, and the other ends of the driving screws are rotationally connected to the positioning plates through threads; and thus, by rotating the ends, located on the inner side surfaces of the transverse moving plates, of the driving screws, the transverse moving plates are driven to move towards the outer sides, interval adjusting of the transverse moving plates is achieved, and the interval between the longitudinal side rollers is adjusted.

Description

technical field [0001] The invention relates to a PET extrusion tooling. Background technique [0002] At present, the PET extrusion tooling can realize the positioning and shaping of the PET sheet just discharged, so as to obtain the PET sheet whose size meets the requirements. PET is in a fluffy state after being foamed and extruded by the extruder. At this time, the PET can be extruded to a specified size to obtain a PET sheet that meets the technical requirements; the current PET extrusion tooling generally includes a bottom plate, a transverse press Roller, longitudinal side roller, install the horizontal pressure roller and the longitudinal side roller on the bottom plate, so that the PET sheet is squeezed through the longitudinal side rollers distributed under the horizontal pressure roller and on both sides, so that the PET sheet is positioned and shaped, However, the PET extrusion tooling of this structure cannot adjust the position of the horizontal pressure rolle...

PET is in a fluffy state after being foamed and extruded by the extruder. At this time, the PET can be extruded to a specified size to obtain a PET sheet that meets the technical requirements; the current PET extrusion tooling generally includes a bottom plate, a transverse press Roller, longitudinal side roller, install the horizontal pressure roller and the longitudinal side roller on the bottom plate, so that the PET sheet is squeezed through the longitudinal side rollers distributed under the horizontal pressure roller and on both sides, so that the PET sheet is positioned and shaped, However, the PET extrusion tooling of this structure cannot adjust the position of the horizontal pressure roller and the longitudinal side roller according to the required size, and cannot adjust the height of the horizontal pressure roller and the distance between the vertical side rollers according to actual needs, so it is very inflexible to use.
