Control system for bypassing material guide and control method thereof

Abstract

The invention discloses a control system for bypassing a material guide and a control method thereof, which belong to the technical field of mechanical grain and feed processing. The control system comprises a human-machine interaction interface, an execution unit and a PLC (programmable logic controller) control unit, the execution unit comprises an air cylinder and an electromagnetic valve for controlling the intake and exhaust of the air cylinder, the PLC control unit comprises a two-way communication interface, a CPU (central processing unit), an analog input module and a digital output circuit, and the human-machine interaction interface is connected with the PLC control unit through the two-way communication interface; the input end of the analog input module is connected with an extruder operating current detection unit, and the output end of the digital output circuit is connected with the electromagnetic coil of the electromagnetic valve. The control method bypasses a guide plate and controls feeding by utilizing the control system to carry out comparison to judge whether the actual operating current value of an extruder is greater than or equal to the operating current expectation of the extruder, and can effectively prevent the occurrence of machine blockage without interrupting material.

Description

technical field [0001] The invention relates to a control system, in particular to a control system of a bypass material guide device, and belongs to the technical field of grain and feed processing machinery. The invention also relates to a control method of the bypass material guide device. Background technique [0002] In the prior art, there is a bypass material guide device, which includes an upper flange and a lower flange. A barrel body with a square cross-section and surrounded by side plates is arranged between the upper flange and the lower flange. One of the barrel bodies There is a bypass outlet on the side plate, a chute is provided at the bypass outlet, and a material guide plate that can be turned over to block the bypass outlet and the passage in the barrel is provided in the barrel, and the bottom of the guide plate is provided with two ends The rotating shaft supported on the staving body is provided with a rocker at one end of the rotating shaft extending...

AI Technical Summary

Problems solved by technology

Its shortcoming is that although the improved bypass material guide device can realize automatic control, it has higher requirements on the control accuracy of the cylinder, especially when slight overload or other special circumstances occur, the control material guide plate is at It is difficult to control a certain middle position of the channel in the barrel in actual production operation, and it is not easy to realize
