Needle bar high-point micro-elastic mechanism of embroidery machine

Abstract

The utility model discloses an embroidery machine needle bar high-point micro-elastic mechanism which comprises a needle bar arranged in a needle bar frame, a cross beam is arranged above the needle bar in the middle of the needle bar frame, an L-shaped elastic piece is arranged on the cross beam, the side face of the elastic piece is fixed on the cross beam through a bolt, the bottom face of the elastic piece corresponds to the top of the needle bar, a gap is reserved between the bottom face and the cross beam, and an oval groove is formed in the side face of the elastic piece. The needle rod is fixed on the cross beam through two bolts, and a similar F-shaped ejector block is arranged at the top of the needle rod. The elastic piece can realize elastic collision between the needle bar and the elastic piece through the elastic bottom surface, so that the abrasion of the needle bar frame and the influence on the driving precision of the cam driving mechanism are avoided, and the normal work of the embroidery machine is ensured. Meanwhile, the vertical height of the elastic piece can be finely adjusted through the oval groove, so that the limiting high point of the needle rod is accurately adjusted, and the adjustment operation is simple and convenient.

Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a high-point micro-elastic mechanism for a needle bar of an embroidery machine. Background Art

[0002] In the existing embroidery machines, when the cam driving mechanism drives the needle bar to work up and down, the needle bar will hit the crossbeam of the needle bar frame when it reaches the highest point. Under long-term impact, the crossbeam of the needle bar frame will be worn, affecting the up and down working accuracy of the needle bar and the driving accuracy of the cam driving mechanism. In severe cases, it will cause problems such as skipped stitches, affecting the embroidery products and the operation of the embroidery machine. Utility Model Content

[0003] The utility model discloses a micro-elastic mechanism at the high point of the needle bar of an embroidery machine, which can realize the elastic collision between the needle bar and the needle bar frame, ensure the working life of the needle bar frame and the cam driving mechanism, and avoid affecting the operation of the embroidery machine. The specific technical scheme is as follows:

[0004] The invention discloses a micro-elastic mechanism for a high point of a needle bar of an embroidery machine, comprising a needle bar arranged in a needle bar frame, a crossbeam arranged above the needle bar in the middle of the needle bar frame, an elastic sheet arranged on the crossbeam, the elastic sheet being L-shaped, the side of the elastic sheet being fixed to the crossbeam by bolts, the bottom surface corresponding to the top of the needle bar, and leaving a gap between the elastic sheet and the crossbeam.

[0005] An elliptical groove is arranged on the side of the elastic sheet and is fixed on the crossbeam by two bolts.

[0006] The top of the needle bar is provided with an F-shaped top block.

[0007] The elastic sheet of the utility model can realize elastic collision between the needle bar and the elastic sheet through the elastic bottom surface, thereby avoiding wear of the needle bar frame and affecting the driving accuracy of the cam driving mechanism, thereby ensuring normal operation of the embroidery machine.

[0008] At the same time, the upper and lower heights of the elastic sheet can be fine-tuned through the elliptical groove, so as to accurately adjust the limit height point of the needle bar, and the adjustment operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the structure of the utility model;

[0010] Figure 2 It is a schematic diagram of the elastic sheet structure of the utility model. DETAILED DESCRIPTION

[0011] like Figure 1-2 As shown, an embroidery machine needle bar high point micro-elastic mechanism includes a needle bar 2 arranged in a needle bar frame 1, a crossbeam 3 is arranged above the needle bar 2 in the middle of the needle bar frame 1, an elastic sheet 4 is arranged on the crossbeam 3, the elastic sheet 4 is L-shaped, and the side surface is fixed to the crossbeam 3 by bolts, the bottom surface corresponds to the top of the needle bar 2, and a gap is left between the crossbeam 3 and the needle bar 2.

[0012] The elastic sheet 4 is provided with an elliptical groove 5 on its side and is fixed to the crossbeam 3 by two bolts 6 .

[0013] The top of the needle rod 2 is provided with an F-shaped top block 7 .

[0014] When the needle bar 2 is lifted up, the top of the needle bar 2 collides with the bottom of the elastic sheet 4 similar to the F-shaped top block 7 to achieve elastic collision. By adjusting the elliptical groove 5 on the side of the elastic sheet 4 and fixing it to the crossbeam 3 with two bolts 6, the needle bar 2 can be fine-tuned to ensure the working accuracy of the needle bar.

[0015] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
