Embodiment 1

[0020] The present invention is improved on the basis of Singer 20U33 machine, as figure 1 As shown, this zigzag double-needle sewing machine includes a machine head 1, a base plate 2, a presser foot 6, a needle plate 7, a needle clip 3 and two machine needles 4 fixedly connected to the needle clip 3, and the machine head 1 is fixed Connected to the bottom plate 2, the needle clamp 3 is connected with the machine head 1, and a detachable mechanism is arranged between the needle clamp 3 and the machine head 1.

[0021] The detachable mechanism in this embodiment includes a needle bar with an external thread structure fixedly connected to the machine head 1 and a connecting rod with an internal thread structure fixedly connected to the needle clamp 3 . The needle clip 3 is fixedly connected with the machine head 1 through the needle bar. Since the needle clip 3 and the needle bar are threaded together, it is very convenient when the needle clip 3 needs to be replaced.

[0022] ...

Embodiment 2

[0026] The content in the second embodiment is roughly the same as that in the first embodiment, except that the detachable mechanism in the first embodiment includes a needle bar with an external thread structure fixed on the machine head 1 and a needle holder 3 fixed on the A connecting rod with an internal thread structure. However, the detachable mechanism in this embodiment includes an insertion rod arranged on the needle clamp 3 and a slot arranged on the machine head 1, the insertion rod is inserted into the slot, and the two are fixedly connected by a latch .

Embodiment 3

[0028] The content in the third embodiment is roughly the same as that in the first embodiment, except that the detachable mechanism in the first embodiment includes a needle bar with an external thread structure fixed on the machine head 1 and a needle holder 3 fixed on the A connecting rod with an internal thread structure. And the detachable mechanism among the present embodiment comprises bolt, nut, through hole one on the needle clip 3 and through hole two on the machine head 1, and bolt passes through through hole one and through hole two and is connected with nut.

Abstract

The invention provides a bent two-needle sewing machine, belongs to the mechanical technical field, and solves the technical problems that the existing bent two-needle sewing machine can not be conveniently installed and maintained, and can not manufacture different three-dimensional stripes. The bent two-needle sewing machine comprises a sewing machine head, a bottom board, a needle clamp and two needles fixedly connected on the needle clamp, wherein, the sewing machine head is fixedly connected on the bottom board; the needle clamp is connected with the sewing machine head; and a detachable mechanism is arranged between the needle clamp and the sewing machine head. The bent two-needle sewing machine has the advantages of high positioning precision of needles, convenient disassembly, assembly, replacement and maintenance, etc.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sewing machine, in particular to a zigzag double-needle sewing machine. Background technique [0002] Common two-needle sewing machines mostly comprise a base plate, a machine head is fixedly connected on the base plate, and various mechanical mechanisms are installed on the machine head and the base plate, and each mechanism coordinates and cooperates to complete ordinary sewing. In order to enable the sewing machine to sew various three-dimensional stripes, it is necessary to rationally design the needle position components, adopt double-needle needle clamps with different specifications, presser feet with different specifications with arc chambers and different specifications with The needle plate with protruding nose, so the ordinary zigzag double needle cannot solve the above problems. Contents of the invention [0003] The object of the present invention is to solve th...
