Method and system for controlling rising and falling sequence of leveling plates of gypsum board production line

Abstract

The embodiment of the invention discloses a method for controlling rising and falling sequence of leveling plates of a gypsum board production line. The method comprises the following steps that datatransmission and control relations among each leveling plate, a processing system and a forming table are established, and each leveling plate is independently connected with the processing system tocomplete respective rising and falling operation; according to the position of each leveling plate away from the forming table and the speed of the gypsum board production line, the rising operation time and the falling operation time of each leveling plate are calculated, so that rolling leveling work of the surfaces of gypsum board materials is achieved; and a synchronous triggering relation between rising and falling of the forming table and rising and falling of the leveling plates is established to achieve automatic bag placing of the boards, and a control system comprises a processing unit, a forming table state monitoring unit, an electric control unit, a timing unit and a timing unit. According to the scheme, the intelligent automatic control system adjusts rising and falling of the leveling plates, and each leveling plate accurately works according to the specifically set rising and falling time point.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of gypsum board production lines, and in particular to a method and system for controlling the lifting and falling sequence of screeds in a gypsum board production line. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. It is one of the new lightweight panels that are currently being developed. [0003] The sheet forming system of the gypsum board production line is composed of a dry material system, a wet material system, a mixing system and an extrusion system. The extrusion system is the key to the production of gypsum board. The extrusion system can be divided into forming table, The three parts of the leveling plate and the wedge-shaped edge chamfer determine the thickness,...

Problems solved by technology

[0007] To this end, the embodiment of the present invention provides a method and system for controlling the rising and falling sequence of screeds in a gypsum board production line. The intelligent automatic control system is used to adjust the rise and fall of the screeds, and each screed works precisely according to the specific set rising and falling time points. Effectively solve the problem of lifting the screed plate too early, which causes the edge of some plates to warp, and lift the screed plate too late, resulting in material accumulation on the screed plate or damage to the edge-holding device
