The embodiment of the invention discloses save 1 under a kind of sewing machine throwing mechanism, including throwing cam 4, lower axle 2, casing, beat
Line actuator 3, speed detector and control device.
The outer peripheral surface of throwing cam 4 is equipped with annular routing slot, and correspondingly, the invention also includes be installed on throwing cam 4
Routing frame 6, routing frame 6 include being installed on the routing plate of annular routing slot and being respectively arranged in first mistake at 4 both ends of throwing cam
Line plate and second crosses line plate.Suture sequentially passes through the first line plate, routing plate and second excessively and crosses line plate and compressed by throwing cam 4,
Until suture is in M type.Throwing cam 4 just tightens a suture for each revolution, and line amount needed for choosing next needle simultaneously.
Lower axle 2 is installed under casing in section 1, can be relative to 1 rotation of section under casing, and the specific mounting means of lower axle 2 can
Referring to the prior art, this will not be detailed here.
Routing actuator 3 is fixed on the side of section 1 under casing, and is connected with throwing cam 4, so as to the drive of routing actuator 3
Dynamic throwing cam 4 rotates.Preferably, routing actuator 3 is servo motor, but the type of routing actuator 3 is without being limited thereto.
Speed detector is installed on lower axle 2, for detecting the revolving speed of lower axle 2.Speed detector can be encoder
Deng being not specifically limited herein.
Control device is connected with routing actuator 3 and speed detector respectively.When lower axle 2 rotates, Rotating speed measring dress
It sets and sends a signal to control device, control device starts routing actuator 3, and routing actuator 3 drives throwing cam 4 to rotate, from
And pass through the tension of 4 adjustable suture of throwing cam, while rotate synchronously routing actuator 3 and lower axle 2.
In conclusion sewing machine throwing mechanism provided by the present invention is not related to V belt translation, bearing and shield etc., a side
Face amount of parts according to the present invention and type are reduced, and structure is naturally relatively simple；On the other hand it is driven using routing
The substitution V belt translation of part 3 advantageously reduces the noise and vibration values of complete machine, and overall performance is promoted naturally.Therefore, institute of the present invention
The structure of the sewing machine throwing mechanism of offer is preferable compared with simple and overall performance.
In addition, it is necessary to explanation, for the existing throwing cam driven by belt wheel mechanism, the present invention is mentioned
The throwing cam 4 of confession is only just able to achieve rotation by routing actuator 3, and related component reduces, convenient while mobile routing
Actuator 3 and throwing cam 4, therefore routing actuator 3 can be moved to optimum position according to required thread tension, thus logical
It crosses and moves throwing cam 4 and adjust gap tension to best.
To realize fixed routing actuator 3, the invention also includes the support plate 5 being fixedly connected with routing actuator 3, support plates

It is without being limited thereto.Lower shaft driver is connected with lower axle 2, for driving lower axle 2 to rotate.The tension suffered by the suture is more than or equal to default
When power, it is meant that suture is tensioned by transition, and pressure-detecting device sends a signal to control device at this time, and control device controls lower axle
Actuator drives lower axle 2 to rotate, while the speed detector for being installed on lower axle 2 sends a signal to control device, control device
3 corner of routing actuator is adjusted, to adjust the corner of throwing cam 4, and then suture is prevented to be pulled off, failure rate is reduced, has
Conducive to the functional reliability for promoting routing.
In addition, the invention also includes temperature-detecting device and cooling device, temperature-detecting device be set to servo motor and with
Control device is connected, for detecting the temperature of servo motor.Cooling device is set to servo motor, for reducing the temperature of servo motor
Degree.When the temperature value of servo motor is higher than preset temperature, to prevent servo motor because own temperature is excessively high, that loss of excitation occurs is existing
As, control device drives cooling device, so that cooling device cools down servo motor in time, so that the temperature of servo motor is reduced,
Failure rate is reduced, is equally beneficial for promoting functional reliability.
Smoothly to realize routing function, the invention also includes routing fixed plate 7, routing shaft 8 and routing adjustable plates 10.Its
In, routing fixed plate 7 is fixed on the side of section 1 under casing by screw, to support routing frame 6.Routing shaft 8, which is fixed on, beats
Thread fixing plate 7, and be rotatablely connected with routing frame 6, so that routing shaft 8 supports routing frame 6 to rotate.The first of routing adjustable plate 10
End is rotatably connected by shipping and reselling on another market with routing fixed plate 7, and the second end of routing adjustable plate 10 is determined with being fixedly arranged on routing frame 6
Position 9 selective incubation of pin, by stirring routing adjustable plate 10 up and down, routing adjustable plate 10 is adjusted on routing frame 6 by positioning pin 9
Lower movement, to make routing frame 6 close to or far from throwing cam 4, to facilitate suture to pass through routing frame 6.
The present invention also provides a kind of sewing machine, including sewing machine body and above-mentioned sewing machine throwing mechanism, sewing machine throwings
Mechanism is installed on sewing machine body, therefore has beneficial effect identical with sewing machine throwing mechanism, and details are not described herein.
Sewing machine provided by the present invention and its type throwing mechanism are described in detail above, it is used herein specifically
Principle and implementation of the present invention are described for a example, the present invention that the above embodiments are only used to help understand
Method and its core concept；At the same time, for those skilled in the art is being embodied according to the thought of the present invention
There will be changes in mode and application range, in conclusion the contents of this specification are not to be construed as limiting the invention.
