Problems solved by technology

[0003] The embroidered fabric of the embroidery machine is not limited to one thickness. Every time before embroidering a new fabric, it is necessary to measure the thickness of the new fabric and adjust the height of the presser foot according to the thickness of the new fabric to adapt to fabrics of different thicknesses. Some technologies use the method of manually adjusting the height of the presser foot, which is time-consuming and labor-intensive, and is prone to quality problems caused by adjustment problems

Embodiment 1

[0029] like figure 1 As shown, this embodiment discloses a presser foot self-adaptive method, which includes the following steps:

[0030] S1. The presser foot is driven by the closed-loop motor, and the current value of the motor is obtained in real time. The closed-loop motor rotates and the presser foot drops. When the presser foot touches the fabric and encounters resistance, the current of the closed-loop motor will increase, so the closed-loop motor can be detected by detecting the closed-loop motor. The current value is used to detect whether the presser foot effectively touches the fabric.

[0031] S2. Determine whether the presser foot is effectively in contact with the fabric according to the current motor current value. When the motor current value is too large, it means that the presser foot contacts the fabric too tightly, and when the motor current value is too small, it means that the presser foot does not completely contact the fabric, so here, when the motor ...

Embodiment 2

[0041] like figure 2 As shown, this embodiment is similar to Embodiment 1, the difference is that this embodiment belongs to the intelligent mode, which can be used for embroidering fabrics with different thicknesses, and is automatically adjusted according to the fabric thickness in real time during the embroidery process. Specifically:

[0042] In the smart mode, steps S1-S3 are:

[0043] S12. Drive the presser foot down, and obtain the motor current value in real time;

[0044] S22. Determine whether the motor current value is within the preset current range, if so, carry out this embroidery, otherwise adjust the motor rotation angle to maintain the motor current value within the preset current range;

[0045] S32. Repeat steps S12 and S22 in the subsequent embroidery process.

[0046] Compared with the first embodiment, this embodiment has a higher degree of intelligence, and is more adaptable to fabrics.

Abstract

The present invention provides a presser foot self-adaptation method, which includes the following steps: S1. driving the presser foot down, and obtaining the motor current value in real time; S2. judging whether the presser foot is effectively in contact with the fabric according to the current motor current value; S3. Embroider while the presser foot is effectively in contact with the fabric. The advantages of the invention are that the height of the cloth presser foot with different thicknesses can be automatically changed, no manual adjustment is required, the adjustment efficiency is improved, and the quality problem caused by the manual adjustment problem can be avoided at the same time.

Description

technical field [0001] The invention belongs to the field of working methods of embroidery machines, in particular to a presser foot self-adaptive method. Background technique [0002] Computerized embroidery machines can be divided into flat embroidery machines, shuttle embroidery machines and towel embroidery machines according to the embroidery process. Through the expansion and innovation of the traditional towel embroidery machine technology, the production efficiency has been greatly improved, and the ever-changing embroidery designs have been displayed. [0003] The embroidered fabric of the embroidery machine is not limited to one thickness. Before embroidering the new fabric, it is necessary to measure the thickness of the new fabric and adjust the height of the presser foot according to the thickness of the new fabric to adapt to fabrics of different thicknesses. The prior art adopts a method of manually adjusting the height of the presser foot, which is time-cons...
