Simulation and Experimental Research on dust collection device of sewing machine

ABSTRACT

As an electric appliance used in textile mills, the suction and dust collecting device of sewing machines is becoming more and more widespread.And the types and functions of vacuum cleaners are also increasing.Therefore, for the study of the performance of industrial dust cleaner has become more and more important, to establish a set of experimental methods for the detection and research based on industrial vacuum cleaner, which can obtain parameters of product characterization of dust, and analyzed the product classification and performance.

Design and implement method of mechanical structure of the test device and the dust suction fan in this paper mainly studies the sewing machine, the wind speed measuring instrument, flow meter, suction device, power supply device, oscilloscope, composition and pressure sensor.The research contents are as follows：

Design of mechanical structure of experimental device.Based on the experimental requirements of the suction and dust collecting device of sewing machine, the scheme is determined.The calculation of the motor, the calculation of the fan, the calculation of the pipeline and the calculation of the pressure of the dust collecting box are carried out through the mathematical model.Through the simulation, the change of pressure under different conditions of the device, the change of flow rate, determine the choice of sensor measurement precision and measurement range, and considering the installation requirements, to determine the sensor selection.According to the selection of sensors and the acquisition system based on the acquisition module, set up the requirements

The subsequent conditioning circuit of the sensor is designed, and the required power supply circuit and interface are designed and built.

Through the recording and research of the experimental data, the data processing and conclusion induction are realized.The experiment platform is set up and tested successfully after the debugging, and the test result is formed.

The results of different experiments are compared, and the reasons and laws affecting the performance are put forward.
