Referring to fig. 1 of the drawings, an embroidery machine with floating color changing includes a machine head 100, a needle bar frame 200, a color changing assembly 300, and a thread stand 400; the machine head 100 can move transversely to match with a large-width tabouret; the needle bar frame 200 is fixedly connected with the machine head 100; color changing assembly 300 is fixedly connected to handpiece 100/needle bar frame 200; the wire frame 400 is arranged on the machine head 100, wherein the wire frame 400 is elastically connected with the connecting frame 210, the elastic connection has an elastic deformation space, and a difference value of motion response exists between the wire frame 400 and the color changing machine head 100 through the elastic deformation space and the connecting frame 210. When the machine head 100 moves in a small amplitude, the wire frame 400 does not act with the machine head 100, so that the purpose of reducing the motion inertia of the whole motion part is achieved; similarly, when the color is changed, if the color changing lateral movement width is small, the thread stand 400 is maintained in a stable state based on the elastic deformation space and does not directly move along with the needle bar frame 200/the color changing component 300.

Regarding the positional relationship between the several components, in one embodiment, the thread stand 400 is disposed above and behind the needle bar frame 200, the color changing assembly 300 is disposed behind the needle bar frame 200, and the color changing assembly 300 is disposed below the thread stand 400.

Specifically, referring to fig. 5 of the present disclosure, the movable block 320 is connected to the color changing connecting plate 310, and the movable block 320 drives the needle bar frame 200 to move after moving, and meanwhile, in order to ensure stable supply of embroidery threads on the needle bar frame 200, the color changing connecting plate 310 directly drives the thread frame connecting plate 500, so as to ensure quick response of the thread frame 400 in the color changing process.

It can be appreciated that a connecting frame 210 is disposed between the needle bar frame 200, the color changing assembly 300 and the thread stand 400, and the connecting frame 210 is used as a basis for driving the thread stand 400 to move; specifically, the color changing assembly 300 connects the needle bar frame 200 and the connection frame 210 by providing a color changing connection plate 310, and the thread stand 400 connects the needle bar frame 200 by providing a thread stand connection plate 500. The core of the differentiation of the thread stand 400 is that the thread stand connection plate 500 is matched with the elastic member 443 on the thread stand 400, the needle bar frame 200 or the connection frame 210 caused by the color changing assembly 300 moves in a small amplitude, and the movement trend is digested by the elastic member 443 and not transmitted to the bearing platform 430 because the amplitude is smaller than the elastic deformation space of the elastic member 443, so that the bearing platform 430 of the thread stand 400 is maintained in a stable state.

The wire frame 400, referring to fig. 2-4 of the drawings, is used for carrying a bobbin wire, and the wire frame 400 has a space for buffering the applied force.

With respect to the floating foundation of the wire frame 400, the wire frame 400 is slidably disposed on the machine head 100, or the wire frame 400 is fixedly disposed on the machine head 100, and a sliding connection structure is provided inside the wire frame 400. A sliding mechanism 420 is further disposed between the carrying platform 430 and the wire frame base 410, and a sliding direction of the sliding mechanism 420 is consistent with a moving direction of the machine head 100, so that the carrying platform 430 moves along with the wire frame connecting plate 500.

The float mechanism 440, referring to fig. 3 of the drawings, is used to cushion the force, causing the motion feedback to lag. The floating mechanism 440 includes a floating frame 441, a supporting shaft 442, and an elastic member 443, wherein the supporting shaft 442 (which is convenient for installation of the elastic member 443 and has guiding function) is disposed on the floating frame 441, and the axial direction of the supporting shaft 442 is consistent with the movement direction of the handpiece 100, and the first is the movement direction of the guide wire frame connecting plate 500, and the second is the deformation direction of the guiding elastic member 443; and the elastic member 443 is sleeved on the support shaft 442, and the elastic member 443 is deformable on the support shaft 442.

It will be appreciated that the rack web receiving area 444 is centrally located with respect to the carrying floor 430; and the first end of the bobbin connecting plate 500 is connected to the central position of the needle bar frame 200; the elastic deformation spaces on both sides of the bobbin-connecting plate receiving section 444 are preferably identical so that the response thresholds of the bobbin 400 to the movement on both sides are identical.

It should be noted that, an adjusting sleeve 445 may be disposed on the supporting shaft 442 (the adjusting sleeve 445 may be flexibly moved on the supporting shaft 442 and fixed on the supporting shaft 442 by a fastening screw, etc.), and the deformation space of the elastic member 443 is adjusted by the adjusting sleeve 445 to adjust the response threshold of the following motion of the wire frame 400.

For the specific illustration of the wire frame connecting plate 500, a clamping portion 510 is disposed at the second end of the wire frame connecting plate 500, and the clamping portion 510 is disposed in the wire frame connecting plate accommodating area 444, and the clamping portion 510 abuts against/connects with the elastic member 443. Of course, a manner of directly fitting the engaging portion 510 over the support shaft 442 is also possible. In addition, the clamping portion 510 and the supporting rod are not contacted, and it is also within the scope of the present application that the clamping portion 510 is directly connected with the elastic member 443.

Similarly, when the handpiece 100 moves in a small range, the bobbin 400 is stationary, and when the handpiece 100 moves in a large range, the bobbin 400 moves.
