As it is shown in figure 1, the present invention provides the overedger of a kind of band needle gage adjustment structure, driver to overedger in the present embodiment
Structure and other structures unrelated with needle gage adjustment structure are not described further, and it is the structure in existing overedger, in the present embodiment
The main shaft 1 of overedger is provided with an eccentric part, and eccentric part is arranged with work feed connecting rod 2, and work feed connecting rod 2 is put with long feeding respectively
Lever 13 is connected with short feeding swing arm 12, long feeding swing arm 13 and work feed curved bar 14 phase being arranged on cloth pushing shaft 15
Even, cloth pushing shaft, main shaft are the structure in transmission mechanism, overedger are additionally provided with needle gage adjustment structure, this needle gage adjustment structure
Including: linkage adjustment mechanism, regulate crank 6 including the first connecting rod 3 being hinged successively, second connecting rod 5 and needle gage, first even
The end of bar 3 is rotatedly connected with the main shaft 1 of overedger, and the end of first connecting rod 3 has an inner sunken face, needle gage regulation song
Handle 6 is all connected with short feeding swing arm 12 transmission on overedger by bearing pin 7 with second connecting rod 5, and needle gage regulation crank 6 is solid
It is scheduled on the needle gage regulation axle 11 parallel with main shaft 1；Drive mechanism, including the regulating part 4 that can move forward and backward, regulating part 4
One end contacts with inner sunken face, drives first connecting rod 3 to rotate when regulating part 4 moves forward, final drive needle gage regulation crank
6 and short feeding swing arm 12 rotated needle gage regulation；Resetting-mechanism, is connected with linkage adjustment mechanism, when regulating part 4 to
During rear motion, resetting-mechanism is used for driving linkage adjustment mechanism to reset.The overedger of the present invention uses needle gage adjustment structure to realize
Singlehanded metering needle away from, only movable linkage adjustment mechanism need to be driven to rotate by it, and then drives by regulation regulating part 4
Short feeding swing arm 12 and needle gage regulation crank 6 turn an angle, and being changed by the position of short feeding swing arm affects long sending
Material swing arm and the drive connection of whole transmission mechanism, make the angle of the reciprocal transmission of cloth pushing shaft change, to complete needle gage
Regulation, it achieves needle gage quickly and easily and is adjusted.
For ease of moving before and after realizing regulating part 4, above-mentioned regulating part 4 is with externally threaded shank of bolt, and shank of bolt is located in
In one carries female abutment sleeve 16, this abutment sleeve is fixed on the casing of overedger.For ease of regulation, regulating part 4
The other end be additionally provided with knob 41, this knob be provided with needle gage regulation scale, can be adjusted intuitively.This drive mechanism is adopted
Rotating with shank of bolt and realize moving forward and backward, it can also be other versions, as long as can realize movable.Rotate rotation
Button 41, makes shank of bolt move forward or retracts backward, and when moving forward, the end of shank of bolt props up above-mentioned first connecting rod 3, and
Order about drive first connecting rod 3 to rotate, and then drive needle gage regulation crank 6 and short feeding swing arm 12 to turn an angle, complete
Needle gage regulates.
As an embodiment, above-mentioned resetting-mechanism can include that reset spring plank 10, torsion spring 9 and rotational positioning are at overedger casing
On needle gage regulation axle 11, this needle gage regulation axle 11 be located in the sleeve 17 being fixed on overedger casing, reset spring plank 10
Being each provided on needle gage regulation axle 11 with torsion spring 9, the one of torsion spring 9 twists leg and the pivot pin 8 on needle gage regulation axle 11 is fixed, torsion spring
Another of 9 twists leg and is connected with the spring plank 10 that resets.The present embodiment uses reset spring plank, torsion spring to realize whole linkage adjustment structure
Reset.When above-mentioned regulating part 4 is moved rearwards by, at this moment reset spring plank 10 regulates crank 6 one to needle gage under the drive of torsion spring 9
Individual rotate the power resetted, finally make whole linkage adjustment structure reset, be also arranged above locating part at reset spring plank, in case answering
Position spring plank rotates excessively.
As another embodiment of resetting-mechanism, resetting-mechanism can also be an extension spring, and one end of extension spring is connected with above-mentioned bearing pin 7,
Can also be connected with above-mentioned needle gage regulation crank 6, the other end of extension spring is fixed.When above-mentioned regulating part 4 is moved rearwards by, drawing
Make above-mentioned bearing pin rotate under the pulling force of spring, and then drive whole linkage adjustment structure to rotate, complete to reset.This resetting-mechanism also may be used
Think other resetting structure forms, only need realize driving linkage adjustment structure to reset.
The present invention is when needs carry out needle gage regulation, and needle gage adjustment structure controllable adjustable crank 6 rotates and can control it and rotates
Angle.And when normally working, sewing length adjustment device control and regulation crank 6 maintains static, and then needle gage regulation axle 11 is made to fix
Motionless.Regulated the setting of crank 6 by the needle gage of different angles, the fulcrum of diverse location is provided for short feeding swing arm 12, from
And (structure of the whole transmission mechanism of overedger is prior art, does not makees at this to change the drive connection of the whole transmission mechanism of overedger
Describe in detail), make the angle of the reciprocating rotation of cloth pushing shaft change, to complete needle gage regulation.
In sum, the overedger of the band needle gage adjustment structure of the present invention, it uses needle gage adjustment structure to realize singlehanded metering needle
Away from, only need to be rotated by its movable drive linkage adjustment mechanism by regulation regulating part, and then drive short feeding swing arm
Turning an angle with needle gage regulation crank, i.e. complete needle gage regulation, it achieves needle gage quickly and easily and is adjusted.So,
The present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
The principle of above-described embodiment only illustrative present invention and effect thereof, not for limiting the present invention.Any it is familiar with this skill
Above-described embodiment all can be modified under the spirit and the scope of the present invention or change by the personage of art.Therefore, such as
All that in art, tool usually intellectual is completed under without departing from disclosed spirit and technological thought etc.
Effect is modified or changes, and must be contained by the claim of the present invention.
