Embodiment approach

[0045] In one embodiment, the S12 specifically includes: when it is detected that the current is greater than the current threshold, then determining that the presser foot touches the embroidery material at the moment when the current becomes larger. In this embodiment, if the instantaneous value of the sudden change of current is detected, it is determined that the presser foot just touches the embroidery material at the moment when the current becomes larger. In another embodiment, when it is detected that the current is greater than the current threshold, it is determined that the presser foot touches the embroidery material at a certain moment before the detection of the above-mentioned current. In this embodiment, the current value that has increased after the current mutation is detected, that is, the presser foot has touched the embroidery material and is still moving downward toward the embroidery material. The time at which the current value is currently detected is l...

Abstract

The invention discloses a presser foot height self-adaptive adjusting method, and belongs to the technical field of embroidery machines. The method comprises the following steps that S1, the current of a presser foot driving motor is detected during embroidering of a first needle, and if the current is suddenly increased, it is determined that the presser foot is in contact with an embroidery material; and S2, the presser foot height of a subsequent needle is determined according to the increased current value. According to the method, the proper presser foot height can be automatically adjusted according to the embroidery material attribute, the preset step is omitted, and the embroidery efficiency and the embroidery quality are improved.

Description

technical field [0001] The invention belongs to the technical field of embroidery machines, and in particular relates to a self-adaptive adjustment method for the height of a presser foot. Background technique [0002] The presser foot drive motor of the embroidery machine drives the presser foot drive mechanism to move, and the presser foot drive mechanism drives the presser foot to rise and fall to do reciprocating linear motion. The lowest position of the presser foot is the cloth presser position, and the height of the presser foot at the cloth presser position is generally fixed. When selecting embroidery materials of different materials, since the height of the presser foot is fixed, the force of the presser foot acting on the embroidery materials is different, which cannot adapt to the pressing requirements of embroidery materials with different properties (including thickness, density, material, etc.), making the completion Embroidery stitch lengths are different, a...
