Description

Technical Field

[0001] The utility model relates to the technical field of ceramic processing, in particular to a ceramic material extrusion and homogenization device. Background Art

[0002] Alumina ceramics are a type of ceramic material with aluminum oxide as the main component, used for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. Alumina ceramics are a widely used ceramic. Because of their superior performance, they have been increasingly widely used in modern society to meet the needs of daily use and special performance. Alumina ceramic tubes are extremely weather-resistant and have strong adaptability to external climates. They are resistant to sunlight, acid rain corrosion, and have stable performance. No paint or protective layer is required on their surfaces and cut edges. They can be glazed directly after fine processing. There are many methods for forming alumina ceramic products, including dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing. In order to improve the quality of the existing alumina ceramic tubes during extrusion molding, it is necessary to mix and homogenize the materials to prevent uneven material distribution from affecting the molding quality.

[0003] A Chinese patent publication (publication number: CN217751904U) discloses a material extrusion and homogenization device for the production of alumina ceramic tubes, which includes a material extrusion and homogenization device body, a mounting plate is provided on the material extrusion and homogenization device body, and a gantry is connected to one side above the mounting plate, a hydraulic cylinder is installed in the gantry, and a material pressing head is connected to the lower end of the hydraulic cylinder, and a material guide hopper is provided above the material pressing head, a driving motor is installed at the upper end of the gantry, and the driving motor is connected to the hydraulic cylinder through a coupling, an extrusion limit cylinder is provided below the material pressing head, and a discharge hopper engaged with the mounting plate is connected to the lower end of the extrusion limit cylinder , and a pressing plate is clamped between the discharge hopper and the extrusion limit cylinder. The material extrusion homogenization device for the production of alumina ceramic tubes can quickly carry out material feeding processing, and at the same time, the pressing head used for extruding the material can be rotated to improve the extrusion effect, thereby improving the production efficiency of the processing device. However, in actual use, the feeding operation of the extrusion limit cylinder requires frequent positioning of the screw feeder, which reduces the feeding efficiency. The extrusion operation cannot be carried out during the feeding process, which reduces the extrusion efficiency. The feed hole opened on the pressing head affects the extrusion effect of the material. Therefore, a ceramic material extrusion homogenization device is proposed. Utility Model Content
