Packing machine small package gold wire servo control device

Abstract

The invention provides a small package gold pull line servo control device of a packaging machine. The small package gold pull line servo control device comprises a system control circuit board, a servo driver, a servo alternating current motor and a first speed feedback device. The system control circuit board is connected with the servo driver, the servo driver is used for driving and controlling the servo alternating current motor, and the servo alternating current motor is connected with a gold pull line connecting rod. The first speed feedback device is arranged between the system control circuit board and the gold pull line connecting rod; and a moment and position feedback device and a second speed feedback device are further arranged between the servo alternating current motor and the servo driver and connected with a grating monitoring system arranged on the rear portion of the servo alternating current motor. Multiple control on speeds, moment and positions is achieved through the small package gold pull line servo control device, a system runs stably and reliably, and breakage of a gold pull line is effectively avoided. The service life of the motor is prolonged, energy consumption is reduced, and noises and thermal energy discharge are reduced.

Description

technical field [0001] The invention belongs to tobacco equipment, in particular to a small package gold wire servo control device for a packaging machine. Background technique [0002] The main components of the original machine of the GD packaging machine small package gold wire drawing motor are as follows: figure 1 As shown, it includes: DC carbon brush motor, motor control circuit board, speed feedback device, the DC motor control board receives external signals to control the speed of the DC carbon brush motor, the speed feedback device performs speed feedback to the motor control circuit board, and motor control The circuit board adjusts the speed control of the motor according to the feedback, forming a single speed closed-loop system. Although some measures such as speed compensation and system feedback have been taken, due to the characteristics of the DC brush motor itself, the carbon brushes and commutators are worn, the life is relatively short, the noise is la...
