Ceramic substrate casting processing equipment

Abstract

The invention discloses ceramic substrate casting processing equipment which comprises a raw material treatment device, a forming device and a post-treatment device. The raw material treatment device comprises a main mixer and an auxiliary mixer, a first mixing mechanism is arranged in the main mixer, a second mixing mechanism is arranged in the auxiliary mixer, and a connecting pipe is arranged between the main mixer and the auxiliary mixer. The forming device comprises a casting rack, a conveying belt arranged on the casting rack, a feeding box arranged on the conveying belt and a scraper arranged on the casting rack, the feeding box is connected with the auxiliary mixer, and the post-treatment device is arranged on one side of the conveying belt. The first mixing mechanism comprises a crushing and screening part and an initial mixing part, the initial mixing part wraps the outer side of the crushing and screening part, the crushing and screening part comprises symmetrically-arranged driving discs and grinding columns movably arranged on the driving discs, center wheels are arranged in the middles of the driving discs, multiple gears engaged with the center wheels and outer gear rings engaged with the gears are arranged on the edges, and through holes are formed in the center wheels.

Description

technical field [0001] The invention relates to the field of ceramic tape casting processing equipment, in particular to a ceramic substrate tape casting processing equipment. Background technique [0002] Electronic ceramics are ceramics with new functions obtained through precise control of surface, grain boundary and size structure. It can be widely used in energy, household appliances, automobiles, etc. The molding method mainly includes: dry pressing molding, isostatic pressing molding, extrusion molding, grouting molding, tape casting molding, hot die casting molding. The most commonly used methods are hot die casting and tape casting. Hot die casting can form complex products, but the forming process is more complicated because it requires multiple high temperatures and consumes energy, and the forming period is also long. It is usually used for specific products. The most mature molding method is tape casting. [0003] Tape casting, also known as belt casting meth...

AI Technical Summary

Problems solved by technology

It mainly solves the problem of uneven drying on both sides, which ensures the cast quality to a certain extent. The appearance of air bubbles in the production process has a great impact on the quality of the cast sheet, and there will be voids and protrusions. , because it cannot be compensated by grinding, so removing the air bubbles in the tape casting raw material is the key to the tape casting process
