Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
Referring to fig. 1-2, a thread trimming mechanism of a sewing machine for producing protective clothing comprises a base 1, wherein the lower end of the base 1 is fixedly connected with a table top through bolts, the upper end of the base 1 is fixedly connected with a plurality of fixing columns 2, the upper ends of the fixing columns 2 are fixedly connected with a transverse plate 3 together, the upper end of the transverse plate 3 is provided with a groove 4, the inner wall of the groove 4 is rotatably connected with two blades 5, the two blades 5 are tightly attached to each other, and it needs to be noted that when the two blades 5 rotate to be close to each other to coincide, a thread end between the two blades 5 can be trimmed;
two spouts 6 have been seted up to 3 lateral wall symmetries of diaphragm, 6 inner walls of two spouts rotate jointly and are connected with double threaded rod 7, 7 lateral wall symmetric thread of double threaded rod has slider 8, slider 8 upper end fixedly connected with riser 9, slider 8 and riser 9 all with 6 inner wall sliding connection of spout, riser 9 is close to recess 4's lateral wall fixedly connected with horizontal pole 10, the one end that riser 9 was kept away from to horizontal pole 10 runs through diaphragm 3 lateral walls and extends to in the recess 4, the one end that riser 9 was kept away from to horizontal pole 10 rotates and is connected with connecting rod 11, the one end that horizontal pole 10 was kept away from to connecting rod 11 rotates with 5 lateral walls below of blade to be connected, horizontal pole 10 and connecting rod 11 adopt high damping material to make, 7 pivoted actuating mechanism of drive double threaded rod are installed to base 1 upper end.
The driving mechanism comprises an electric push rod 13 fixedly connected to the upper end of the base 1, a rack 14 is fixedly connected to the movable end of the electric push rod 13, and the double-threaded rod 7 penetrates through the side wall of the transverse plate 3 and is fixedly connected with a gear 12 meshed with the rack 14.
