Air blowing control device for sewing equipment

Abstract

The invention discloses a blowing control apparatus of sewing equipment. The blowing control apparatus comprises a micro-pressure sensor for inducing airflow output by an operator's mouth and outputting control voltage according to airflow pressure, an adjustable connecting rod for bearing the micro-pressure sensor and adjusting the distance between the micro-pressure sensor and the operator's mouth, a head-mounted frame for bearing the adjustable connecting rod, and a connecting wire which transmits operating voltage of the micro-pressure sensor and drives a control module to the servo motor of the sewing equipment to transmit the control voltage output by the micro-pressure sensor, wherein the induction range of the airflow pressure of the micro-pressure sensor is in the range from 0 to 10 Pa, and the output range of the corresponding control voltage is in the range from 0 to 1.25V. According to the blowing control apparatus of the sewing equipment, the manipulation mode of using a pedal plate can be broken, and the blowing manipulation mode of the operator's mouth can be realized.

Description

technical field [0001] The invention relates to an air blowing control device of sewing equipment. Background technique [0002] The servo motor of the sewing equipment is generally equipped with a servo motor drive control module, and the servo motor drive control module controls the operation of the servo motor according to the control voltage input from the outside. At present, the external control voltage is generally provided by the pedal. [0003] The working principle of the foot pedal control is as follows: apply the principle of magnetic induction, the closer the magnet is to the magnetic induction triode, the larger the analog signal output by the triode, and vice versa, there will be no output without induction. The greater the pressure of the operator on the pedal, the greater the control voltage output by the pedal, the control voltage is directly transmitted to the servo motor drive control module, the greater the speed of the servo motor, the operator does no...

AI Technical Summary

Problems solved by technology

[0005] Seated control pedal, the operator needs to sit and work for a long time, the production efficiency is low, and sitting for a long time, the operator is prone to cervical and lumbar diseases

[0006] Compared with the sitting pedal, the standing pedal is more beneficial to the operator, and can avoid cervical and lumbar diseases caused by sitting for a long time. However, the operator generally only uses one foot to step on the pedal, and the other foot is always standing , working for a long time is more tiring, prone to leg swelling and leg pain

[0007] And the particularity of sewing equipment is that the sewing speed and time are not qualitative. The operator should flexibly change the sewing speed and time according to the material, thickness, position, and process requirements of the sewing fabric, which requires the operator's legs and feet It is necessary to control the pressure of the pedals according to the needs, and the legs are always in a state of high-intensity and rapid change of force, which is very easy to fatigue
