Abstract
The invention discloses a thread clamping mechanism for a needle rod of an embroidery machine. The thread clamping mechanism comprises a machine head and the needle rod, wherein the needle rod is mounted on the machine head; a thread clamping spring is arranged on the needle rod; the upper end of the thread clamping spring is fixed to a rod body of the needle rod by screws; the lower end of the thread clamping spring is bent at the bottom end of the needle rod; a gap is formed between the lower end of the thread clamping spring and the bottom end of the needle rod; the middle section of the thread clamping spring is projected outwards; a stop block is arranged on the machine head; and the outward projection part of the thread clamping spring is pressed by the inner wall surface of the stop block when the needle rod is in a lift-up state.
Description
Technical field
The present invention relates to a kind of embroidery machine broken thread detector, particularly a kind of embroidery machine needle bar cramp line mechanism.
Background technology
Existing thread depressing mechanism demand motive source, such as motor or electromagnet, this line ball mode is complex structure not only, and the risk that exists line ball to lose efficacy.
Summary of the invention
The objective of the invention is to design a kind of embroidery machine needle bar cramp line mechanism.
What the present invention will solve is existing embroidery machine thread depressing mechanism, demand motive source and complex structure and the problem that has the line ball failure risk.
For realizing purpose of the present invention, the technical solution used in the present invention is: it comprises head and shank, shank is installed on the head, shank is provided with Trap shell splinter, the upper end of Trap shell splinter is screwed on the shank shaft, curved the tearing open in the shank bottom and with the bottom in the lower end of Trap shell splinter left the gap, vault outside the stage casing of Trap shell splinter, and head is provided with block; Under the shank propradation, the internal face of block is pushed down the outer vault place of Trap shell splinter.
Advantage of the present invention: the present invention need not independent line ball drive source (motor or electromagnet), and when being in non-embroidery state in the pin position, Trap shell splinter is depressed, and pushes down upper thread.When the embroidery state, Trap shell splinter unclamps, and upper thread can freely pass through.Line ball action of the present invention, simple in structure, without the line ball failure risk.
Description of drawings
Structural representation when Fig. 1 is the non-embroidery state of the present invention (shank rising).
Structural representation when Fig. 2 is embroidery state of the present invention (shank decline).
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in the figure, the present invention includes head (not drawing) and shank 1, shank 1 is installed on the head.Shank 1 is provided with Trap shell splinter 3, and the upper end of Trap shell splinter 3 is fixed on the shank shaft with screw 2.Curved the tearing open in the shank bottom and with the bottom in the lower end of Trap shell splinter 2 left gap 6.Vault outside the stage casing of Trap shell splinter 3, head are provided with block 4.Under shank 1 propradation, the internal face 7 of block 4 is pushed down the outer vault place 8 of Trap shell splinter 3.
