AI Technical Summary

Technical Problem

The existing fabric carriages have limited functionality, resulting in complex structures for pressure molding machines. They require multiple independent template drive mechanisms and scraper/push plate drive structures, leading to redundant operation steps.

Method used

Design a multi-functional fabric rolling trolley that integrates templates and push plates onto the trolley, combined with a mixing device, to achieve integrated functions of powder filling, molding, and plaster block pushing, simplifying the structure and optimizing the production process.

Benefits of technology

The structure of the pressure molding machine has been simplified, the cost has been reduced, the production efficiency has been improved, the timing coordination problem between multiple actuators has been avoided, the control is simple and reliable, the uniformity of powder mixing has been improved, and the stability of gypsum block pushing has been enhanced.

Abstract

This invention relates to a pressure molding machine for producing α-type hemihydrate gypsum and its multi-functional material feeding carriage. The material feeding carriage includes a frame with a hopper on it. The hopper has an upper inlet and a lower outlet. Along its direction of travel, a template and a gypsum block pushing structure are sequentially arranged on one side of the hopper on the frame. The gypsum block pushing structure includes a pusher plate, which pushes the gypsum blocks ejected upwards from the mold as the frame moves. The material feeding carriage has a first working position, a second working position, and a third working position during its forward and backward movement along the frame. By directly mounting the template and pusher plate on the frame of the material feeding carriage, the three main functions of material feeding, template compaction with the mold and top pressure block, and gypsum block pushing are integrated into a single material feeding carriage. This reduces the number of parts in the machine, simplifies the structure, and lowers costs. Through the orderly movement of the material feeding carriage between the first, second, and third working positions, the filling, compaction, and pushing of finished gypsum blocks into the mold are achieved respectively, without interruption, thus improving production efficiency.
