Description
Technical field
The utility model relates to a kind of thorn material feeding mechanism based on dual drive, belongs to technical field of sewing machines.
Background technique
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 traditional overedger is driven using spindle eccentricity, by the effect of connecting rod and crank, to realize such as overedger
Pierce the movement of material；Cloth pushing shaft is driven by complicated connecting rod crank, complicated needle gage component control cloth pushing shaft swings, send to realize
The movement of material and the size for changing needle gage.For this thorn material feeding mechanism in the presence of structure is complicated, installation maintenance is inconvenient, and to cloth thickness
Many defects such as the adaptability of degree is weak.
Summary of the invention
The purpose of this utility model is to solve current thorn to expect that feeding machine structure is complicated, installation maintenance is inconvenient and thick to cloth
The weak technical problem of the adaptability of degree.
To realize the above purpose of utility model, the utility model provides a kind of thorn material feeding mechanism based on dual drive,
The first driver and the second driver including casing and fixed installation on the housing；
Needle bar crank is installed on the output shaft of first driver, drives the shank bent by the swing of output shaft
Handle is swung, and the shank component connecting with needle bar crank is made to pump；
Differential crank and feeding crank are installed on the output shaft of second driver, pass through the second driver output shaft
Swing drive the swing of the differential crank and feeding crank, thus drive respectively the differential retainer being connect with differential crank and
The feed dog frame connecting with feeding crank moves forward and backward.
Further, first driver and the second driver are the device of rotary reciprocating motion, including but not limited to
Motor and electromagnet.
Further, the needle bar crank is mounted on the output shaft of the first driver directly or by shaft coupling.
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 utility model has the beneficial effects that：
Change of the utility model by the oscillating quantity of the first driver and the second driver, the stroke and work feed for expecting thorn
The size of needle gage changes, and simplifies equipment transmission mechanism greatly by the cooperation of the two, and to the adaptability of cloth thickness
It is stronger.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in figures 1 to 6, the thorn material feeding mechanism based on dual drive of the utility model, the output of the first driver 1
Needle bar crank 2 is fixedly installed on axis, the other end of needle bar crank 2 is connect by pin with shank component 3, the first driver 1
It drives needle bar crank 2 to swing by the swing of output shaft, so that shank component 3 be made to pump, realizes thorn material movement,
By changing 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 opposite joint
The thickness of material is more adaptable；Differential crank 5 and feeding crank 8, differential song are fixedly installed on the output shaft of second driver 4
Handle 5 and feeding crank 8 are connect by axial screw with differential retainer 6 and feed dog frame 7 respectively, 4 output shaft of the second driver
It swings and differential crank 5 and feeding crank 8 is driven to swing, to make 7 front-rear reciprocation movement of differential retainer 6 and feeding retainer, pass through
The amount of moving forward and backward of differential retainer 6 and feed dog frame 7 can be changed in the swing angle for changing the output shaft of the second driver 4, thus
Realize the change of needle gage size.
By the change of the oscillating quantity of the first driver 1 and the second driver 4, make to pierce the big of the stroke and cloth sending needle distance expected
Small change simplifies equipment transmission mechanism greatly by the cooperation of the two, and to the more adaptable of cloth thickness.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
