An embroidery machine presser foot control system

Abstract

The present invention relates to the technical field of embroidery machines, and discloses an embroidery machine presser foot control system, which includes a controller, a spindle encoder, a presser foot motor control board and a presser foot motor. The control board is connected with the main control system, and the presser motor control board is connected with the presser motor and the machine head control board. The spindle encoder is used to detect the working state and position of the spindle, and send the signal to the controller; the controller is used to send the signal of the spindle encoder to the main control system and the presser motor control board, and disconnect the main control The spindle encoder signal obtained by the system stops the embroidery machine from working. The embroidery machine presser foot control system and the main control system of the present invention are independent of each other, and the working state of the embroidery machine can be automatically judged by obtaining the signal of the main shaft encoder, the lock signal and the mending embroidery signal, and the above signals and the working state of the embroidery machine can be Accurately control the synchronous movement of the presser foot and the needle bar, and can also actively disconnect the signal of the main shaft encoder to stop the embroidery machine, ensuring the safety of the equipment of the embroidery machine.

Description

technical field [0001] The invention relates to the technical field of embroidery machines, and in particular discloses an embroidery machine presser foot control system. Background technique [0002] Embroidery machine, also known as embroidery machine, is an advanced embroidery machine in modern times. It can achieve high-speed and high-efficiency traditional manual embroidery, and can also achieve "multi-level, multi-functional, uniform and harmonious" that cannot be achieved by manual embroidery. perfection" requirement. It is an electromechanical product that embodies a variety of high-tech. As computer embroidery replaces manual embroidery, embroidery machines will also become the main models in the embroidery industry. [0003] During the working process of the embroidery machine, the power device drives the needle bar to move up and down through the transmission mechanism to realize embroidery. In order to compress the fabric, the needle bar frame is also provided...

AI Technical Summary

Problems solved by technology

[0004] At present, the presser foot is independently driven by a separate motor to directly control the presser foot. The presser foot moves up and down between the preset highest position and the cloth press position. Because the spindle speed that drives the needle bar moves constantly changes, it is difficult for the presser foot to keep pace with the spindle. Completely unified, the presser foot will deviate when it is raised and lowered, resulting in lower precision of the presser foot. Therefore, it is necessary to provide a presser foot control system for embroidery machines to ensure that the presser foot and the needle bar move synchronously.
