Description
Technical field
The utility model relates to a kind of Sewing machines, is specifically related to a kind of tangent line driving mechanism of Sewing machines.
Background technology
Existing Sewing machines, its tangent line foot lifting mechanism generally adopts solenoid actuated mode.Sensitive not due to electromagnet reaction, cause tangent line to lift circulation timei long, thereby make operating efficiency low.
Also there is the impulse motor of employing directly to drive, but due to impulse motor limited torque output, cause lifting of tangent line, presser feet lifting mechanism unstable, when encountering thick line, be not easy to cut off line.In addition, if adopt impulse motor, location need be regulated by inductor, is again open cycle system, can cause motor location inaccurate, causes the phenomenon of positioning to occur.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of tangent line driving mechanism of Sewing machines, and it can realize the accurate location to needle plate.
For solving the problems of the technologies described above, the technical solution of the tangent line driving mechanism of the utility model Sewing machines is:
Comprise tangential servo motor, the output shaft of tangential servo motor connects the driving wheel of tangent line change gear pair, and the driven pulley of tangent line change gear pair is fixedly connected with tangential cam; Tangential cam and tangent line roller form cam mechanism, and tangent line roller is fixedly connected with one end of tangent line crank, and the other end of tangent line crank connects one end of tangent line connecting rod, and the other end of tangent line connecting rod connects needle plate.
Described tangential servo motor is through the moving tangential cam rotation of tangent line change gear subband, tangential cam drives tangent line crank-motion by tangent line roller, realizing to rotatablely move is converted into rectilinear motion, and tangent line crank drives needle plate to move up and down by tangent line connecting rod, thereby realizes thread cutting action.
Described tangential servo motor is forward motor, reverse motor or rotating motor.
Described tangential cam is symmetrical structure.
The technique effect that the utility model can reach is:
The utility model is simple in structure, and driving force is large, and registration is quick on the draw, and debugging is convenient, and operating efficiency is high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram of the tangent line driving mechanism of the utility model Sewing machines;
Fig. 2 is partial exploded view of the present utility model.
Description of reference numerals in figure:
7 is tangential servo motor, and 8 is tangential cam,
9 is tangent line crank, and 10 is tangent line connecting rod,
11 is tangent line roller, and 12 is that tangent line change gear is secondary,
16 is needle plate.
The specific embodiment
As shown in Figure 1 and Figure 2, the tangent line driving mechanism of the utility model Sewing machines, comprises tangential servo motor 7, and the output shaft of tangential servo motor 7 connects the driving wheel of tangent line change gear pair 12, and the driven pulley of tangent line change gear pair 12 is fixedly connected with tangential cam 8; Tangential cam 8 forms cam mechanism with tangent line roller 11, and tangent line roller 11 is fixedly connected with one end of tangent line crank 9, and the other end of tangent line crank 9 connects one end of tangent line connecting rod 10, and the other end of tangent line connecting rod 10 connects needle plate 16;
Tangential servo motor 7 drives tangential cam 8 rotations through tangent line change gear secondary 12, tangential cam 8 drives 9 motions of tangent line crank by tangent line roller 11, realizing to rotatablely move is converted into rectilinear motion, tangent line crank 9 drives needle plate 16 to move up and down by tangent line connecting rod 10, thereby realizes the thread cutting action after sewing finishing.
Tangential servo motor 7 can be forward motor, reverse motor or rotating motor.
Tangential cam 8 is symmetrical structure, so that revolving force size and its irrelevant to rotation direction that cam rotation is transmitted.
Driving principle of the present utility model is as follows:
The rotary driving force of tangential servo motor 7 strengthens by the conversion of tangent line change gear pair 12, changes the driving force to tangent mechanism into; Tangent line roller 11 slides and driving force is passed to tangent line connecting rod 10 along the cam path of tangential cam 8, and tangent line connecting rod 10 pulls the low moving knife of needle plate 16, completes thread cutting action.
