Embodiment 1

[0036] In this embodiment, a polymer plasticizing transport method based on extrusion stretching, the volume of the transport space used to transport polymer materials realizes periodic changes from small to large and then from large to small; in the transport space When the volume changes from small to large, polymer materials are forced into the transport space; during the process of changing the volume of the transport space from large to small, polymer materials are compacted and plasticized by normal stress, and then forced to Discharge, so as to rely on the volume change of the transport space to realize the positive displacement transport and plastic transport of polymer materials.

[0037] In order to realize the polymer plasticization transportation method based on extrusion stretching, this embodiment provides a polymer plasticization transportation module, such as Figure 1 to Figure 3As shown, a set of transport unit 1 is included; the transport unit 1 includes a s...

Embodiment 2

[0044] This embodiment is a polymer plasticizing transport module, the difference from Embodiment 1 is that in this embodiment, the feed port 16 is not arranged on the stop plate 1, but is arranged in the stator 11, and the feed port 16 communicates with the head end of the transport space 18, such as Figure 4 shown. In practical applications, the discharge port may not be arranged on the second retaining plate, but on the stator, and the discharge port communicates with the end of the transport space. The rest of the structure of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0046] This embodiment is a polymer plasticizing transportation method based on extrusion stretching, the difference from Embodiment 1 is that in this embodiment, multi-stage transportation spaces are used to transport polymer materials in series in phase sequence; each stage The volume of the transport space realizes periodic changes from small to large and then from large to small; during the process of changing the volume of the transport space from small to large, polymer materials are forcibly incorporated into the transport space; when the volume of the transport space changes from small to large In the process of changing from large to small, the polymer material is compacted and plasticized by normal stress, and then forced to discharge, so as to realize the plasticized transportation of the polymer material with multi-stage pressurization and speed-up.

Abstract

The invention provides a macromolecule plasticizing transportation method based on extrusion and stretching, and a macromolecule plasticizing transportation module, device and equipment. The method comprises the steps that the size of a transportation space for transporting macromolecular materials is periodically changed from small to large and then from large to small in sequence; in the processthat the size of the transportation space is changed from small to large, the macromolecular materials are forcibly contained in the transportation space; and in the process that the size of the transportation space is changed from large to small, the macromolecular materials are compacted and plasticized under the action of normal stress and then are forcibly discharged, and therefore forward transportation and plasticized conveying of the macromolecular materials are achieved through size change of the transportation space. According to the method, the module, the device and the equipment,the thermo-mechanical process of the plasticizing transportation process can be shortened, the plasticizing transportation energy consumption is reduced, the transportation efficiency is improved, andthe equipment size and occupied space are reduced.

Description

technical field [0001] The present invention relates to the technical field of plasticizing and transporting polymer materials, and more specifically, to a polymer plasticizing and transporting method, module, device and equipment based on extrusion stretching. Background technique [0002] The energy consumption of polymer material molding is high. Since the 1930s, screw machinery has been widely used, such as screw extruder, screw injection machine, etc., but whether it is extrusion product processing, or injection, calendering, In the processing of blow molding and other products, plastic raw materials must go through the basic and common process of solid transportation and melting plasticization. The energy used in this process accounts for the vast majority of energy consumption in polymer material processing. [0003] In the screw machine, the solid transportation of the material mainly depends on the friction and drag of the screw on the material when the screw rotate...
