The invention relates to a sewing device and a sewing method, which utilize the function of an auxiliary presser foot to press a target object into a placement hole of a main presser foot in the sewing process, thereby being safe and efficient.
The invention is realized by the following technical scheme:
the sewing device comprises a main presser foot, a main presser foot bottom plate, a sewing machine head and a needle, wherein a placement hole for placing a target object is formed in the main presser foot, the needle is arranged on the sewing machine head and can move up and down relative to the sewing machine head in the Z direction, the main presser foot bottom plate is positioned below the main presser foot, the main presser foot and the main presser foot bottom plate are in linkage in an XY plane, and the main presser foot can move up and down relative to the main presser foot bottom plate in the Z direction; the sewing machine head is also provided with an auxiliary presser foot for pressing objects in the placing hole, and the auxiliary presser foot is simultaneously abutted against the main presser foot. The auxiliary presser foot is provided with a linear guide rail in the Z direction, the linear guide rail is fixed with the sewing machine head, and the auxiliary presser foot can only move together with the main presser foot along the linear guide rail in the Z direction under the action of the main presser foot.
Through the technical scheme, the auxiliary presser foot is abutted against the main presser foot and presses the target object, the auxiliary presser foot is not required to be driven by other power sources, the structure is simple and ingenious, the target object is not tilted in the sewing process, the pressing of hands on the target object is avoided, and the sewing is attractive and safe.
As a further development of the invention, the auxiliary presser foot is provided with an elastic member or a cylinder for keeping the auxiliary presser foot against the main presser foot. Through the technical scheme, the auxiliary presser foot continuously abuts against the main presser foot, the auxiliary presser foot can only move together with the main presser foot in the Z direction under the action of the main presser foot, and the auxiliary presser foot is simple and ingenious in structure, and convenient to install and replace.
As a further improvement of the invention, the auxiliary presser foot comprises a horizontal extension section, on which a guide hole for the organic needle is provided. Through the technical scheme, the needle guide hole is convenient for the needle to pass through so as to sew the target object.
As a further improvement of the invention, the upper plane of the main presser foot is provided with a wire containing groove. Through the technical scheme, since the auxiliary presser foot is always abutted against the main presser foot, after the thread is sewn, the thread is possibly clamped between the auxiliary presser foot and the main presser foot, and the thread accommodating groove is arranged to facilitate the thread cleaner of the sewing device to sweep out the thread head, so that the next round of sewing is facilitated.
As a further improvement of the present invention, the thickness of the main presser foot is greater than or equal to the thickness of the object. Through the technical scheme, the thickness of the main presser foot is larger than or equal to that of the object, and the auxiliary presser foot can always and smoothly slide on the object in the sewing process; if the thickness of the main presser foot is smaller than that of the target object, namely the target object exceeds the upper plane of the main presser foot, the auxiliary presser foot pushes the target object out of the placement hole when moving from the initial position to the target object, and the sewing is not facilitated.
The sewing method adopting the sewing device of any one of the technical schemes to carry out sewing comprises the following steps:
A. placing a cloth between the main presser foot and the main presser foot bottom plate; the auxiliary presser foot presses the main presser foot to place Kong Liuchu on the main presser foot;
