Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as Figure 1-4 As shown, the presser foot control method for inflatable fabrics comprises the following steps:
[0031] A. Set the working origin of presser foot 1: Presser motor 2 drives presser foot 1 back to the working origin, collects the pulse signal of the rotation angle of the output shaft of presser motor 2 at this position, and converts the collected pulse signal Send to PLC controller 3;
[0032] B. Set the working low point of the presser foot 1: the output shaft of the presser motor 2 drives the presser foot 1 down to the working point where the cloth pressing can be realized, and collects the pulse of the rotation angle of the output shaft of the presser motor 2 at this position signal, the pulse signal collected is transmitted to the PLC controller 3;
[0033] C. Set the working high point of presser foot...

The invention provides a presser foot control method for an expansion fabric and a control mechanism thereof, and solves existing technical problems. According to the presser foot control method for the expansion fabric and the control mechanism thereof, the method comprises the following steps that A, a working origin point of a pressing presser foot is set, wherein a presser motor drives the pressing presser foot to return to the working origin point, a pulse signal of the rotation angle of an output shaft of the presser motor at the position is collected, and the collected pulse signal is transmitted to a PLC; B, a working low point of the pressing presser foot is set, wherein the output shaft of the presser motor drives the pressing presser foot to be lowered to a working point where cloth pressing work can be achieved, a pulse signal of the rotation angle of the output shaft of the presser motor at the position is collected, and the collected pulse signal is transmitted to the PLC; C, a working high point of the pressing presser foot is set. The presser foot control method for the expansion fabric and the control mechanism thereof have the advantages of high precision and thelike.
Description
technical field [0001] The invention belongs to the technical field of embroidery machines, and in particular relates to a presser foot control method and a control mechanism for inflatable fabrics. Background technique [0002] Embroidery machines have replaced traditional hand embroidery and are widely used to make various embroidery. Today, as the degree of automation is getting higher and higher, computerized embroidery machines have the characteristics of high efficiency and high speed that cannot be achieved by traditional manual embroidery methods. Generally, an embroidery machine is provided with a needle bar, a presser foot and a transmission device for driving the needle bar and the presser foot. The presser foot of the embroidery machine needs high-speed reciprocating operation, and its trajectory is controlled to be stable and reliable, so as to ensure the smooth thread binding of the needle bar, which is also an element to ensure good embroidery stitches. Most...
