Automatic electronic tug of sewing machine

Abstract

The invention provides an automatic electronic tug of a sewing machine, and relates to the technical field of sewing machines. The automatic electronic tug comprises a big arm, a small arm, a tug, a driving component, a pressure regulating component, a regulating component, a hairbrush component, a control main board, and a display operation screen, wherein the big arm is arranged on an engine body; the small arm is rotatably arranged at one end of the big arm; the tug is rotatably arranged on the small arm; the driving component is arranged on the big arm and is used for driving the tug to rotate; one end of the pressure regulating component is rotatably arranged on the big arm, and the other end of the pressure regulating component is articulated on the small arm; the regulating component is arranged on the big arm and is used for driving the pressure regulating component to drive the tug to lift and drop; the hairbrush component is arranged at the side, close to the tug, of the small arm; the control main board is arranged in the big arm and is electrically connected to the driving component and the regulating component; the display operation screen is arranged at one side of the big arm and is electrically connected to the control main board; and a lifting key for controlling the tug to lift and drop is arranged on the display operation screen. By adopting the technical scheme, the automatic electronic tug has the advantages of convenient operation, reasonable structure, high degree of automation, and being conductive to improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to an automatic electronic tug wheel for sewing machines. Background technique [0002] With the continuous development of science and technology and the textile industry, the technology of sewing machines has become more and more mature, and there are more types, including not only household sewing machines, but also industrial sewing machines used in industry, such as lockstitch sewing machines, chain sewing machines, Overlock sewing machine and interlock sewing machine, etc. [0003] Among them, the tug wheel is located behind the head of the sewing machine. Its main function is to press the garment template and drive the garment template forward during the process of sewing and processing fabrics, thereby replacing manual dragging actions, reducing the work intensity of employees, and facilitating sewing. The stitches are even and avoid wrinkling of the fabric. [0004...

AI Technical Summary

Problems solved by technology

[0004] But the degree of automation of the sewing machine tug wheel device in the prior art is not high, and it is very inconvenient to use

There are mainly the following deficiencies: 1. When the tugboat is not needed, the screws are usually manually loosened to lift the tugboat as a whole. When the replacement product needs to be used, it needs to be reinstalled, so the lifting of the tugboat is very troublesome and inconvenient sewing operation

2. The display and operation screen of the existing tugboat is installed on the main control box or an independent object is installed on the sewing machine head. The main control box is placed separately under the operating table. The operator needs to bend down to look at the data and operate and adjust.

However, an independent display operation panel screen has insufficient installation location convenience and obstructed operator's line of sight.

3. Since multiple sewing threads are often used in the sewing process, the existing tugboat will pull the remaining thread ends on the fabric after multiple turns and wind them around the tugboat. After multiple turns, it will The drawing of the fabric will affect the integrity of the fabric, or the tugboat will be stuck
