Embodiment Construction

[0022] Please refer to Figure 1, which is a three-dimensional schematic diagram of the present invention. As shown in the figure, the upper thread holding device 10 of the sewing machine is configured to be set in a sewing machine (not shown in this figure), which is mainly composed of a power source 1 , The transmission mechanism 2, the linkage mechanism 3, the wire buckling mechanism 4 and the fixing frame 5. The power source 1 is pivotally connected to the transmission mechanism 2, the transmission mechanism 2 is pivotally connected to the linkage mechanism 3, and the linkage mechanism 3 is pivotally connected to the buckle mechanism 4. The fixing frame 5 is used to fix the device on the sewing machine. Each mechanism uses a pivot to achieve mutual linkage between each mechanism.

[0023] The power source 1 is composed of a pneumatic cylinder 11 and a pneumatic source 12.

[0024] The transmission mechanism 2 is composed of a driving arm 21, a driving arm seat 22, a pin 23, a ...

Abstract

The invention relates to an upper threading retainer for sewing machines. The upper threading retainer mainly makes for some special places during garment making process, so that a wire body on a sewing machine can be quickly put into location. The invention particularly relates to an upper threading retainer to allow threading though a slope in the wire body, and horizontally moving threads into location. The structure comprises a dynamic power source, a drive mechanism, a linkage mechanism, a thread lacing mechanism and a fixed framework. The dynamic power source is connected with the drive mechanism; the drive mechanism is linked to the linkage mechanism; the linkage mechanism is coupled with the thread lacing mechanism. The invention provides an upper threading retainer that can be provided between a needle bar moving structure and a colth cutter structure, in order to eliminate extruders on the side wall of the arm, and improve operation accuracy. In addition, the upper threading retainer can convert the movement of the thread lacing unit into a horizontal displacement for thread lacing through a displacement conversion, so as to effectively stablize upper threading effects; moreover, the invention can provide an upper threading retainer with precise operation to meet sewing demands.

Description

Technical field [0001] The invention relates to a thread holding device of a sewing machine. The thread holding device of the present invention is mainly used for special occasions in the manufacturing process of clothing, so that the thread body of the sewing machine can be quickly sent to the positioning. The invention particularly refers to an upper thread holding device which enables the thread body to enter the thread from an inclined plane and then move horizontally to a positioning. Background technique [0002] When operating some industrial sewing machines with special functions, the first stitch will often skip stitches, which will affect the product quality. For example, when the buttonhole sewing machine is making buttonholes, the first stitch will pick up the needle. During the wearing of the clothes, the thread may fall off, which affects the sewing quality of the buttonhole. In order to ensure the sewing quality, you need to manually pinch the upper thread when s...
