Novel multi-bin electric control device

Abstract

The invention relates to a novel multi-bin electric control device and belongs to the technical field of automated control equipment of textile enterprises. The device is constituted by a PLC central processing unit, an interconnection and mutual control unit, a power unit and the like; the device is characterized in that the PLC central processing unit is connected with an input control unit, an output control unit, a pneumatic execution unit, an indicating unit, the interconnection and mutual control unit, a safety protection unit and the power unit; the safety protection unit is composed of a primary line protection assembly and a secondary line protection assembly; the power unit is composed of a draught fan, beater motors and cotton feeding motors. By means of the novel multi-bin electric control device, accuracy and smoothness of front and rear interconnection and mutual control are guaranteed, blowing-carding operating efficiency is improved, maintenance is facilitated, and the failure rate of a multi-bin cotton blending machine is lowered; the problems that in the prior art, contacts are in poor contact easily, and the circumstances that stepping cannot be conducted to the right positions, route selection is not correct, route selection is conducted orderlessly, or route selection is omitted occur frequently, so that a cotton bin valve is clamped, a cotton conveying pipeline is blocked, front and rear interconnection and mutual control are in disorder, the process flow is even interrupted, and blow-carding operating efficiency is severely lowered are solved.

Description

technical field [0001] The invention relates to a novel multi-chamber electric control device, which belongs to the technical field of automatic control equipment for textile enterprises. Background technique [0002] The multi-compartment blending machine plays a key role in the entire blowing-carding process of cotton textile technology. Its front and rear interconnection and mutual control and the accuracy of the sequence action of multiple cotton warehouse valves, the cotton volume of each warehouse and the switching control of each warehouse pressure Whether it is in place is related to the failure rate of equipment, which directly affects the production cost and economic benefits of textile enterprises. In the past, the multi-bin blender [0003] Electrical appliances and pneumatic control are all completed by relays. Since textile machinery operates in a dusty environment, the mechanical contacts of relays are easily oxidized and dusty and cause poor contact. At the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method that ensures accurate and smooth interconnection and mutual control, improves the operation efficiency of the entire blowing-carding unit, facilitates maintenance, and effectively reduces the failure rate of multi-bin cotton blending machines; to solve the mechanical contact problem of existing relays It is very easy to have poor contact, such as insufficient stepping, incorrect line selection, random line selection or no line selection at all, etc., resulting in valve jamming in the cotton warehouse, blockage of cotton delivery pipes, confusion of front and rear interconnection and mutual control, and even interruption of the entire system. Process flow, a new multi-bin electronic control device that seriously reduces the operating efficiency of the entire blowing-carding unit
