Automatic control system of aluminum soil splitting machine

Abstract

The invention discloses an automatic control system of an aluminum soil splitting machine, and relates to the technical field of splitting machine automatic control. According to the automatic control system, a tension signal of a coiled material and the current diameter of a coiling block are detected in real time through a tension sensor and a phase type laser range finder correspondingly, an electrical proportional valve is controlled in real time, and therefore a pneumatic brake device is controlled, and tension of the equipment is automatically and stably controlled. Operating data of a wind-up roll is detected in real time through an incremental encoder, the operating linear speed of the equipment can be stably controlled, and meter number control can also be achieved. Control over the left-right movement of a wind-up seat and a pay-off seat is achieved through an infrared photoelectric sensor, it is guaranteed that the wind-up seat and the pay-off seat are oppositely flushed all the time. According to the automatic control system, under stable control over the tension and the operating speed of the equipment, the effective work rate of the splitting machine is increased, and the rejection rate is reduced. The automatic control system is high in control precision, good in reliability and capable of effectively preventing equipment overspeed accidents, and the safe and stable work of the equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automatic control of a slitting machine, in particular to an automatic control system of an aluminum foil slitting machine. Background technique [0002] As we all know, the slitting machine plays a vital role in the processing of aluminum foil terminal products, and different customers have different slitting requirements, and the tension required for each product is different. Therefore, Tension control is the core of slitter control. Tension control refers to the ability to permanently control the tension of raw materials when they are conveyed on the equipment. It must be effective for any operating speed of the equipment, including the acceleration, deceleration and constant speed of the machine. Even in the case of emergency shutdown, it should be able to ensure that the cut objects are not damaged. The stability of tension control is directly related to the quality of slitting products. If the te...

AI Technical Summary

Problems solved by technology

The stability of tension control is directly related to the quality of slitting products. If the tension is insufficient, the raw material will drift during operation, which will cause the finished product to wrinkle after slitting and rewinding; if the tension is too high, the raw material will be easily broken, causing the After cutting and rewinding, the number of end breaks in finished products increases

[0003] However, the factors that affect the fluctuation and change of tension are more complicated. For example, the change of the lifting speed of the equipment will cause the change of the tension of the whole equipment; during the winding and unwinding process of the slitting machine, the change of the diameter of the winding and unwinding will cause the change of the tension of the raw material ;The change of the tightness of the raw material will cause the change of the tension of the whole equipment; the fluctuation of the elasticity of the coil, the change of the thickness of the coil, the eccentricity of the coil quality, etc. will cause the fluctuation of the tension. Therefore, in order to achieve stable control of the tension, it is necessary to Multi-factor detection and control related factors to achieve the purpose of stable tension control
