Description
Technical field
The present invention relates to a kind of thorn material feed mechanism based on dual drive, belongs to sewing machine technique field.
Background technology
With the development of the times, requirement of the garment enterprise to sewing device is higher and higher, especially requires to improve to sewing
Adaptability, wherein such as overedger, traditional overedger is driven using spindle eccentricity, by the effect of connecting rod and crank, to realize
Pierce the action of material；Cloth pushing shaft, complicated needle gage component is driven to control cloth pushing shaft and swing, sent to realize by complicated connecting rod crank
The action of material and the size for changing needle gage.There are complicated, installation maintenance inconvenience for this thorn material feed mechanism, and to cloth thickness
Many defects such as the adaptability of degree is weak.
Invention content
Present invention aim to address current thorn material feeding machine structure complexity, installation maintenance inconvenience and to fabric thickness
The weak technical problem of adaptability.
To realize that the above goal of the invention, the present invention provide a kind of thorn material feed mechanism based on dual drive, including casing
And the first driver and the second driver of fixed installation on the housing；
Needle bar crank is installed on the output shaft of first driver, drives the needle bar crank to put by the swing of output shaft
It is dynamic, so that the shank component being connect with needle bar crank is pumped；
Differential crank and feeding crank are installed on the output shaft of second driver, pass through the pendulum of the second driver output shaft
The dynamic swing for driving the differential crank and feeding crank, to drive respectively the differential retainer being connect with differential crank and with give
The feed dog frame of material crank connection moves forward and backward.
Further, first driver and the device that the second driver is rotary reciprocating motion, including but not limited to
Motor and electromagnet.
Further, the needle bar crank is mounted on directly or by shaft coupling on the output shaft of the first driver.
Further, the differential crank and feeding crank are mounted on second driver directly or by shaft coupling
On output shaft.
Further, the differential crank is connect by the first axial screw with the differential retainer；
The cloth feeding crank is connect by the second axial screw with the feed dog frame.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention by the change of the oscillating quantity of the first driver and the second driver, make thorn material stroke and cloth sending needle distance it is big
Small change makes equipment transmission mechanism greatly simplify by the cooperation of the two, and to the more adaptable of cloth thickness.

Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in figures 1 to 6, the thorn material feed mechanism of the invention based on dual drive, on the output shaft of the first driver 1
It is installed with needle bar crank 2, the other end of needle bar crank 2 is connect by pin with shank component 3, and the first driver 1 passes through
The swing of output shaft come drive needle bar crank 2 swing, to make shank component 3 pump, realize thorn material action, pass through
Change the swing angle of the output shaft of the first driver 1, the stroke that shank component 3 moves up and down can be changed, be allowed to sewing
Thickness is more adaptable；Differential crank 5 and feeding crank 8, differential crank 5 are installed on the output shaft of second driver 4
It is connect respectively with differential retainer 6 and feed dog frame 7 by axial screw with feeding crank 8, the swing of 4 output shaft of the second driver
It drives differential crank 5 and feeding crank 8 to swing, to make 7 front-rear reciprocation movement of differential retainer 6 and feeding retainer, passes through change
The amount of moving forward and backward of differential retainer 6 and feed dog frame 7 can be changed, to realize in the swing angle of the output shaft of second driver 4
The change of needle gage size.
By the change of the oscillating quantity of the first driver 1 and the second driver 4, make thorn material stroke and cloth sending needle distance it is big
Small change makes equipment transmission mechanism greatly simplify by the cooperation of the two, and to the more adaptable of cloth thickness.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
