Problems solved by technology

[0002] Existing sewing machines are usually equipped with a cloth mop, and the mop is continuous dragging. During the sewing process, the needle has already penetrated into the fabric, and the mop is still dragging the cloth at this time, and the needle will organize The movement of the fabric causes both the needle and the fabric to be subjected to a horizontal force. When the force is large enough, it will cause the needle to break or the fabric to tear, affecting the yield

Embodiment Construction

[0021] The invention provides a method for controlling a sewing machine, comprising a processor, a main shaft, a machine needle, a needle plate, an encoder and a mop machine, the main shaft drives the needle to move up and down, the encoder is installed on the main shaft, The data output end of the encoder is connected with the coded data input end of the processor, the needle plate is located under the needles, and the mopping wheel of the mopping machine is in contact with the workbench of the sewing machine. The output end of the processor is connected with the input end of the motor of the mop machine, and the method includes:

[0022] The rotation of the main shaft drives the needle to move up and down, and at the same time the main shaft drives the encoder to rotate coaxially. There are two sensing angles inside the encoder, which are the first sensing angle and the second sensing angle. At the first sensing angle, at this time, the needle will be inserted into the cloth...

Abstract

The invention relates to a control method for a sewing machine. The method comprises a processor, a main shaft, a needle, a needle plate, an encoder and a cloth dragging machine, wherein the main shaft is used for driving the needle to move up and down; the encoder is arranged on the main shaft; the data output end of the encoder is connected with the encoded data input end of the processor; the needle plate is positioned below the needle; a cloth dragging wheel of the cloth dragging machine is in contact with a workbench of the sewing machine; the output end of the processor is connected with the input end of a motor of the cloth dragging machine. Due to the arrangement of the encoder, an intermittent cloth dragging function is realized, the cloth dragging machine rotates when the needle is positioned above the needle plate and stops rotating when the needle is inserted into cloth, the perfectness ratio of the cloth can be ensured, and the service life of the needle is prolonged.

Description

technical field [0001] The invention relates to a sewing machine control method, which belongs to the textile field. Background technique [0002] Existing sewing machines are usually equipped with a cloth mop, and the mop is continuous dragging. During the sewing process, the needles have penetrated into the fabric, and the mop is still dragging the cloth at this time, and the needles will organize The movement of the fabric causes the needle and the fabric to be subjected to a horizontal force. When the force is large enough, it will cause the needle to break or the fabric to tear, affecting the yield. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides a sewing machine control method, which can realize that when the needle is above the needle plate, the cloth mop rotates, and when the needle is inserted into the cloth, the mop stops rotating, which can ensure the integrity of the cloth , improve th...
