Description
Technical field
The utility model relates to sewing machine technique field, particularly relates to a kind of thread cutting mechanism of Sewing machines.
Background technology
General cutting facility structure is very complicated, and this cutting facility all has moving knife and stationary knife, in the time of sewing finishing, is driven and is made moving knife motion tangent with stationary knife by Spindle Motor, will extend reaching the standard grade and rolling off the production line of getting off and cuts off from processing cloth automatically; In prior art, after cutting facility completes, the parts of broken string because not having to fix or clamp, can arbitrarily wave, the Efficiency Decreasing of sewing, and after maintenance trimming, breaking stable is the technology that needs in the market solution.
Utility model content
The technical problems to be solved in the utility model is the thread cutting mechanism that proposes a kind of Sewing machines that improves sewing efficiency.
For solving the problems of the technologies described above, the utility model adopts following scheme:
A kind of thread cutting mechanism of Sewing machines, comprise the needle plate, stationary knife, moving knife and the driving mechanism that are provided with winding installing port, stationary knife is located at the circumferential side lower part of winding installing port, moving knife is located at a circumferential upper lateral part of winding installing port, driving mechanism rotates to arrange with moving knife and is connected, moving knife can do relative shearing motion with stationary knife, and the circumferential middle side part of described winding installing port is provided with a clamp, and this clamp is provided with a hole slot.
Above-mentioned stationary knife and clamp are towards winding installing port one end all in the slewing area in moving knife upper end and tangent with moving knife respectively.
Above-mentioned driving mechanism comprises connecting rod, connecting axle and bidirectional electromagnet, and connecting axle one end is rotated to arrange with connecting rod and is connected, and the other end is fixedly connected with the axle core of bidirectional electromagnet.
The beneficial effects of the utility model are: the circumferential middle side part of the set winding installing port of the utility model is provided with a clamp that offers hole slot, after bidirectional electromagnet work drives moving knife to rotate, moving knife continues while taking broken string to clamp position and jointly clamps broken string with clamp after line is cut off, the line cutting off can not waved back and forth, thread cutting mechanism is simple in structure, improves sewing efficiency.
