Drum machine based on intelligent double closed-loop control and control method thereof

Abstract

The invention discloses a drum machine based on intelligent double closed-loop control and a control method thereof. The drum machine comprises a drum mechanism, a paper-feeding mechanism and a microprocessor; the frame of the drum machine is also provided with a humidity sensor, a keyboard and a revolution speed sensor, wherein the upper and lower ends of the inclined plate of the drum mechanism are separately provided with one photoelectric sensor used for detecting the rolling-down speed of paper tubes; the microprocessor is connected with a cutter through a pneumatic drive mechanism; the output end of the microprocessor is connected with the opening control end of a proportional valve, a proportional valve with adjustable opening is arranged on a water pipe between a nozzle group and a water source; and the microprocessor is provided with a revolution speed controller and a water-spraying capacity controller. The control method of the invention adopts the combination of fuzzy control and PID control and combines scanning successive approximate optimal closed-loop control strategy so as to well solve the control problem of spraying water on paper and fully embody the intellectualization of the system. The drum machine of the invention has low cost, high adaptability and high yield of paper tubes.

Description

technical field [0001] The invention belongs to the field of fireworks reel machines and their control, and designs a reel machine based on intelligent double closed-loop control and a control method thereof. The roll machine of the present invention is especially suitable for making paper rolls with a length of 50-150 cm or even longer. Background technique [0002] Existing reel machines are mainly small reel machines suitable for making small-sized paper tubes, and the length of the finished paper tubes is 10-15cm; for making fireworks paper tubes with a length of 50-150cm or even longer, due to technical requirements Not the same, therefore, the small reel machine cannot be applied at all. The existing large reel machine only has a reel mechanism and no paper feeding mechanism, and manual assistance is required for paper feeding, and it is also necessary to manually apply water or glue on one end of the paper to seal the paper cylinder, so the degree of automation is lo...

Problems solved by technology

[0002] Existing reel machines are mainly small reel machines suitable for making small-sized paper tubes, and the length of the finished paper tubes is 10-15cm; for making fireworks paper tubes with a length of 50-150cm or even longer, due to technical requirements Not the same, therefore, the small reel machine is simply not applicable

The existing large reel machine only has a reel mechanism and no paper feeding mechanism, and manual assistance is required for paper feeding, and it is also necessary to manually apply water or glue on one end of the paper to seal the paper cylinder, so the degree of automation is low , low production efficiency

Moreover, because the defective rate of paper tubes has a great relationship with the amount of glue or water, it is difficult to apply glue or water evenly, so the consistency of paper tube products is poor and the defective rate remains high.
