Abstract
The utility model discloses a kind of trimming structures, are made of cylinder, trimming mounting plate, guide rod fixed ring, trimming guide rod, trimming pressure spring, blade, tension disc, crimping offset plate；The cylinder is connected with trimming mounting plate by screw；The blade is fixed by screws on trimming mounting plate；The guide rod fixed ring determines screw by gold with trimming guide rod and is fixed together, trimming guide rod passes through trimming fixed plate via hole, trimming pressure spring is through on trimming guide rod, and trimming guide rod and tension disc are fixed together by holding screw, and tension disc is pasted together with crimping offset plate.The utility model reduces machining accuracy, improves service life, and stable working state is suitble to be used for a long time, reduces maintenance.
Description
Technical field
The utility model relates in four side machine systems, more particularly to four side machines of lock, after the transverse joint applied to four side machines of lock
Bottom surface line is sheared, this structure is not only simple in structure novelty, and durable, needs cutting for dynamic stationary knife to simplify
Cable architecture, and reduce installation and machining accuracy.
Background technique
Trimming structure on general sewing device is mostly based on dynamic stationary knife structure, either flat push type or revolving
It is all to need two edges to be overlapped to be used to cut line, installation accuracy is high, and dynamic stationary knife gap will be bonded closely, in some applications
Dynamic stationary knife to be made into it is separable, so it is difficult to ensure that stability, is in addition also prone to wear, so being directed to the disadvantage of existing structure
End, a kind of trimming structure for not needing stationary knife of the present utility model, after line is pushed down by the pressing plate of two sides, blade is fallen
Line is cut off.
Summary of the invention
The purpose of the utility model is to overcome in place of above-mentioned the deficiencies in the prior art, a kind of trimming structure is provided, it should
Structure does not need to be cut off simultaneously using stationary knife with a hilt bottom surface line.
The purpose of this utility model is achieved through the following technical solutions:
A kind of trimming structure, by cylinder, trimming mounting plate, guide rod fixed ring, trimming guide rod, trimming pressure spring, blade, crimping
Plate, crimping offset plate composition；The cylinder is connected with trimming mounting plate by screw；The blade is fixed by screws in
On trimming mounting plate；The guide rod fixed ring determines screw by gold with trimming guide rod and is fixed together, and trimming guide rod is passed through and cut
Thread fixing plate via hole, trimming pressure spring are through on trimming guide rod, and trimming guide rod and tension disc are fixed together by holding screw, pressure
Line plate is pasted together with crimping offset plate.
The advantages of the utility model and beneficial effect are:
The utility model overcomes the drawbacks of trimming needs stationary knife, allows a set of independent device to integrate, reduces
Machining accuracy, improves service life, and stable working state is suitble to be used for a long time, reduces maintenance.
Detailed description of the invention
Fig. 1 is that cutting facility is mounted on schematic diagram on head of sewing machine；
Fig. 2 is trimming working state schematic representation；
Fig. 3 is a kind of trimming structural perspective.
1. 5. trimming mounting plate of head of sewing machine 2. trimming structure, 3. needle plate, 4. cylinder, 6. guide rod fixed ring
7. trimming guide rod
8. 11. crimping offset plate of trimming pressure spring 9. blade, 10. tension disc, 12. holding screw.
Specific embodiment
For the content, feature and effect that can further appreciate that the utility model, the following examples are hereby given, and cooperates attached
Detailed description are as follows for figure.It should be noted that the present embodiment be it is descriptive, be not restrictive, cannot thus limit this reality
With novel protection scope.
A kind of trimming structure, by cylinder, trimming mounting plate, guide rod fixed ring, trimming guide rod, trimming pressure spring, blade, crimping
Plate, crimping offset plate, holding screw composition；The cylinder is connected with trimming mounting plate by screw；The blade passes through
Screw is fixed on trimming mounting plate；The guide rod fixed ring is fixed together with trimming guide rod by holding screw, trimming
Guide rod passes through trimming mounting plate via hole, and trimming pressure spring is through on trimming guide rod, and trimming guide rod and tension disc are solid by holding screw
It is scheduled on together, tension disc is pasted together with crimping offset plate.
For head of sewing machine after having sewed, control system can give one electric signal of trimming cylinder solenoid valve, and trimming cylinder is opened
Begin to fall, drive trimming fixed plate and other all parts to fall downwardly together, push down line after crimping offset plate is fallen on needle plate,
Cylinder continues to fall, and crimping offset plate pushes down line from blade two sides, and trimming pressure spring is in trimming guide rod by trimming fixed plate and crimping
The pressure contractions of plate cause line to be crushed between crimping offset plate and needle plate, and cylinder band cutting blade continues to fall, and blade falls into needle plate
Indentation, there；After blade falls to a certain extent, line is withdrawn by sliding trackle, cylinder, and trimming pressure spring pressure is discharged from compressive state,
Tension disc resets to reset condition by the power that trimming pressure spring stretches, and guide rod fixed ring locks trimming guide rod end, plays reset
The effect of limit.
