Extrusion type thread making machine

Abstract

The invention belongs to the field of co-extruders, and specifically discloses an extrusion type thread making machine. Through a main scheme, a cladding material extrusion sleeve is coaxially fixedlyconnected with a fiber extrusion pipe, a heat transfer gap exists between the cladding material extrusion sleeve and the fiber extrusion pipe, an extrusion port of the cladding material extrusion sleeve and an extrusion port of the fiber extrusion pipe communicate to a thread outlet pipe respectively, a heat transfer sleeve is fixed on an extrusion screw, stirring blades are fixed on the extrusion screw, the stirring blades are positioned inside the cladding material extrusion sleeve, the heat transfer sleeve comprises a heat transfer inner sleeve and a heat transfer outer sleeve, each of theheat transfer inner sleeve and the heat transfer outer sleeve is respectively provided with a cavity, the end part of the heat transfer inner sleeve is communicated with the end part of the heat transfer outer sleeve, the heat transfer inner sleeve is positioned inside the heat transfer gap, the heat transfer outer sleeve sleeves the outside of the cladding material extrusion sleeve, the outer wall of the fiber extrusion pipe is fixedly connected with a fixed stirring blade, and the end, away from the fixed position of the fiber extrusion pipe, of the fixed stirring blade is connected into the heat transfer inner sleeve in a sliding manner. According to the device, the heating efficiency is improved, and the heating cost is reduced.

Description

Technical field [0001] The invention belongs to the field of co-extrusion machines, and particularly relates to a double-layer composite wire extruder head. Background technique [0002] The alloy grid is an important part of the battery, and its role in the battery: 1. It is mainly to support the active material; 2. The current is evenly distributed on the active material to improve the utilization rate of the active material. The traditional alloy grid is mainly composed of a grid frame with tabs and vertical ribs and horizontal ribs fixed in the grid frame. Among them, the vertical ribs are arranged between the upper and lower frames of the grid frame, and the horizontal ribs are arranged in two Between the vertical borders. [0003] Although the alloy grid does not participate in the flow reaction in the battery, it has a great influence on the main performance of the battery, such as capacity, life, current discharge and charge acceptance. The main function of the grid frame...
