Automatic feeding and discharging roll forming production line and roll forming method thereof

Abstract

The invention relates to the field of ceramic production equipment, in particular to an automatic feeding and discharging roll forming production line and a roll forming method thereof. The productionline is characterized in that the automatic feeding and discharging roll forming production line comprises a roll forming machine, a feeding conveyor, a drying conveyor, a mold removal platform, a dryer, an air blower, a centering mechanism, a mold feeding and discharging mechanism and an excess material recovery mechanism. During roll forming, an upper forming mold descends along with a lower swing arm and is attached to the top face of a plaster mold, the upper forming mold is made of silica gel and seeps water through water permeable holes, and sliding resistance is reduced while attachment to the plaster mold is guaranteed. The upper forming mold and the plaster mold are matched for roll forming, so that the ceramic with the folded upper part can be produced, and the processing cost,weight and processing difficulty of plaster are reduced; redundant mud and excess materials are scraped off by a scraper, fly into a recovery material cavity of the excess material recovery mechanismunder the action of the rotating centrifugal force of the plaster mold, and are stirred into slurry for recycling by adding water.

Description

technical field [0001] The invention relates to the field of ceramic production equipment, in particular to an automatic loading and unloading rolling forming production line and a rolling forming method thereof. Background technique [0002] Roll forming is developed from rotary blank forming. It is to change the type knife into a rolling head. The rolling head and the model rotate around a fixed axis respectively, and the plastic mud put in the model is stretched and pressed into a green body, and the shape and size of the green body are completely determined by the "cavity" formed by the rolling head and the die surface. The rolling method can be divided into male die rolling and female die rolling. Compared with rotary blank forming, roll forming has the advantages of high density, high mechanical strength, small deformation, low labor intensity, and easy mechanization and automatic production. The rolling production line is to complete the forming, body drying, demou...

AI Technical Summary

Problems solved by technology

The loading and unloading of the existing rolling production line is turned 90 degrees by the vertical belt conveyor and the horizontal belt conveyor and fed into the mold base. With this structure of the production line, the horizontal belt conveyor will increase the production line capacity. In addition, when the existing gypsum mold is used to produce ceramics with closed openings, it is necessary to use a double-covered gypsum mold, that is, two separable half-moulds need to be set inside the outer mold. Gypsum has problems such as high production cost, complicated disassembly, and heavy weight. In addition, when the mold is removed and placed on the belt conveyor, the mold itself is not easy to center, which leads to the inability to accurately load the mold onto the mold base.
