Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0035] see figure 1 , figure 1 It is a schematic flow chart of the noise reduction method of the sewing machine of the present invention.

[0036] In this embodiment, the noise reduction method includes:

[0037] Step 100, acquiring a position signal corresponding to the cloth position.

[0038] Generally, when fabrics are sewn on the needle table, the feed dog is set under the needle plate, and there is a tooth hole on the needle plate that allows the top of the cloth feed dog to protrude from the surface of the needle plate. A presser foot is arranged at the correspo...

Abstract

The invention relates to a noise reduction method of a sewing machine, a computer device and a sewing machine. The noise reduction method comprises the steps that a position signal corresponding to afabric advancing position is acquired, and the height of a feed dog is correspondingly adjusted according to the position signal. By adopting the method, when a signal about that a fabric is about toarrive at a presser foot is acquired, the feed dog is adjusted to reach the position during working; when a signal about that the fabric is about to be away from the presser foot is acquired, the feeddog is adjusted to reach an initial position, the initial position makes the feed dog avoid the presser foot, the friction movements between the feed dog and the presser foot are decreased, accordingly abrasion and unnecessary noise of sewing machine parts are decreased, the service life is prolonged, and the use comfort level is improved.

Description

technical field [0001] The invention relates to the field of clothing sewing, in particular to a noise reduction method for a sewing machine, computer equipment and a sewing machine. Background technique [0002] When the existing sewing machine is sewing fabrics, when the fabric is out of the range of motion of the presser foot and the feed dog, the sewing machine will continue to sew for a period of time. The noise becomes louder, and the long-term frictional movement is likely to cause wear to the presser foot and the feed dog, thus affecting the normal use of the whole machine. All existing sewing machines cannot avoid this problem. Contents of the invention [0003] Based on this, it is necessary to address the noise problem when the sewing machine is empty, and to provide a noise reduction method, computer equipment and a sewing machine that can reduce the noise when the sewing machine is empty, and reduce the friction between the feed dog and the presser foot. sew...
