High-speed producing and controlling method for plaster plates

Abstract

The invention discloses a high-speed producing and controlling method for plaster plates. The high-speed producing and controlling method comprises a feeding and discharging step, a forming step and a plate cutting-off step. The feeding and discharging step comprises the following substeps of: monitoring the weight of materials in a hopper in real time; comparing a monitored result with a set value; controlling discharging speed according to a comparison result; comparing the monitored result with a first set value and a second set value; and beginning to feed materials to the hopper from a feed bin or stopping feeding the materials to the hopper from the feed bin according to the comparison result. The forming step comprises a plate defect monitoring step. The plate defect monitoring step comprises the following substeps of: monitoring defects of plate products in a plate forming process in real time; comparing a monitored result with a preset controlling index; and adjusting production programs according to a comparison result. The plate cutting-off step comprises the following substep of: controlling a dual-servo motor to respectively drive an upper cutter and a lower cutter to simultaneously cut off plates on a production line according to the conveying speed of the plates on the production line. The high-speed producing and controlling method can meet requirements on large-scale and high-speed production of the plaster plates.

Description

technical field [0001] The invention relates to a production technology of gypsum board, in particular to a high-speed production control method of gypsum board. Background technique [0002] Plates such as gypsum boards are commonly used materials in the construction field. With the increase of market demand for plates, more and more plate manufacturers use high-speed production lines to increase the production volume of products per unit time. The existing gypsum boards are automated and continuous. The production line mainly includes several stages such as raw material preparation (mixing, feeding and unloading, calcination, etc.), extrusion molding, and plate cutting. However, the existing gypsum board production line is not suitable for high-speed production of products. For example, in In the raw material preparation stage, starch is one of the very important auxiliary materials. When controlling the loading and unloading of starch, manual loading and unloading or auto...

Problems solved by technology

During the forming process, the agglomeration will affect the fluidity of the slurry, and when the slurry travels with the forming paper surface and passes through the shaping platform, it will scratch the paper surface of the gypsum board and cause slurry leakage, which will result in high-speed production. The phenomenon of paper breaks seriously affects the continuity and stability of large-scale gypsum board production

In the plate cutting stage, the high-speed production line transports the plates quickly, and the tangent speed of the cutter must be the same as the plate conveying speed of the production line, so the high-speed rotation of the double cutters is required. The traditional single motor driving the double cutters will increase the load on the motor. load, it is easy to damage the motor, and the double cutter has a large torque during high-speed rotation, which is easy to cause damage to the motor when it is stopped, and when the machine is running, the double cutter takes a long time to start, which reduces production efficiency
