Presser foot control system of embroidery machine

Abstract

The invention relates to the technical field of embroidery machines, and discloses a presser foot control system of the the embroidery machine. The system comprises a controller, a main shaft encoder, a presser foot motor control board and a presser foot motor; the controller is connected with the main shaft encoder, the presser foot motor control board and a main control system; and the presser foot motor control board is connected with the presser foot motor and a machine head control board. The main shaft encoder is used for detecting the working state and position of a main shaft and sending a signal to the controller; and the controller is used for sending the signal of the main shaft encoder to the main control system and the presser foot motor control board, and disconnecting the signal, acquired by the main control system, of the main shaft encoder to stop the embroidery machine. The presser foot control system of the embroidery machine and the main control system are mutually independent; the working state of the embroidery machine is automatically judged by obtaining the signal of the main shaft encoder, a lock head signal and an embroidery supplementing signal; a presser foot and a needle rod can be accurately controlled to move synchronously according to the signals and the working state of the embroidery machine; and the signal of the main shaft encoder can be actively disconnected to stop the embroidery machine, so that the equipment safety of the embroidery machine is ensured.

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.
