Intermittent rotary achievees the effect that feeding；
Pull rod one is equipped with branch's pull rod three, and pull rod three connects vertical bar, and vertical bar is connected to the upper feed mechanism of control
On pull rod on axis, while drawing-inroller adjustment mechanism feeding, pull rod one moves back and forth, and pull rod three is driven equally to move back and forth,
It is identical as the swinging axle principle of feed mechanism to pull the axis of axis feed mechanism on cam of upper feed mechanism to swing, together
The movement that sample passes through gear and the upper feed mechanism of unidirectional Bearing control；
Meanwhile bevel gear seven is correspondingly provided on the axis of bevel gear six, backstitching magnet control mandril by lower feeding pushes
Box body, in sliding slot intrinsic displacement, gear five engages after being detached with bevel gear six with bevel gear seven box body, by changing gear five and umbrella
The engagement of gear six, bevel gear seven can make spur gear pair to rotation.It is sent again by other intermediate gears and universal joint drive
The forward and reverse rotation of material wheel, reaches feeding effect；
Presser foot lifter magnet control bar rotation, to drive vertical axis to rotate, then, the cam on vertical axis top turns
Dynamic, cam pulls drawstring to control take-up linkage；
Universal joint three controls driving wheel rotation, and driving wheel drives driven wheel rotation, then controls drawing-inroller rotation and send
Material, the axis of the presence of locating rod one and locating rod two, driven wheel are swung centered on locating rod one, and oscillator arc is fixed for another
Position ring arc annular distance moral radian, driving wheel is different from feeding tooth number, perimeter difference, after the axle offset of driven wheel, drive from
Driving wheel deviates, and driven wheel changes with drawing-inroller distance of center circle, and drawing-inroller moves up or glides, and completes to adjust.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
