Abstract
The utility model belongs to the technical field of sewing machinery, in particular to a cutting mechanism of the sewing machine. The utility model aims to provide a cutting mechanism of sewing machine for addressing the problems in prior art, such as inconvenient handling, difficulty in adding other devices and liability to failure. The technical proposal of the utility model is that the cutting mechanism of sewing machine comprises a cutter assembly and a drive unit; a cutter arm is arranged in the cutter assembly and an electromagnet is arranged inside the drive unit. The utility model is characterized in that, the drive unit also comprises an iron core and a restoring spring; one end of the iron core is positioned into the electromagnet, and the other end is connected with the cutter arm; a restoring spring is arranged on the iron core, and also arranged between the electromagnet and the cutter arm.
Description
Affiliated technical field:
The utility model relates to technical field of sewing equipment, is specifically related to a kind of Sewing machines die mechanism.
Background technology:
Sewing machines die mechanism is installed in the Sewing machines head, and in order to chop things such as cloth, the end of a thread off, it comprises die assembly and driven unit, and the die assembly comprises upper and lower die and the die arm that connects with it, and this die arm connects with driven unit.The electromagnet that uses rotation to drive in the present driven unit, this structural volume is big, weight is big, and the syndeton complexity, thus carrying inconvenient, increase other device difficulty, and easy break-down.
Summary of the invention:
The utility model will provide a kind of Sewing machines die mechanism, overcoming carrying inconvenience that prior art exists, can not increase other device, and troublesome problem.
For overcoming the problem that prior art exists, the technical solution of the utility model is: a kind of Sewing machines die mechanism, comprise die assembly and driven unit, comprise die arm 4 in this die assembly, comprise electromagnet 1 in this driven unit, its special character is, also comprise iron core 2 and back-moving spring 3 in the driven unit, one end of described iron core 2 is arranged at electromagnet 1 inside, the other end connects with die arm 4, iron core 2 is provided with back-moving spring 3, and this back-moving spring 3 is pressed and is located between electromagnet 1 and the die arm 4.
Compared with prior art, the utility model has the advantages that:
1, can effectively increase work efficiency: this mechanism drives for the electromagnet Straight pull, and spring reset is easy to adjust, and therefore the action high efficient and reliable can effectively increase work efficiency.
2, convenient in carrying: the electromagnet volume is little, and weight is little, convenient in carrying.
3, can increase other device: because volume is little, provide the space for other device is set, operating personnel's working space increases simultaneously.
4, easy break-down not: this is simple in structure, and athletic performance is simple, and therefore easy break-down has not reduced maintenance cost.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Description of reference numerals is as follows:
1-electromagnet, 2-iron core, 3-back-moving spring, 4-die arm, 5-following die, 6-upward dies.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to accompanying drawing, the utility model comprises die assembly and driven unit, said die assembly comprises die arm 4, goes up die 6 and following die 5, and said driven unit comprises electromagnet 1, iron core 2 and back-moving spring 3, wherein goes up die 6 and is fixedly connected with die arm 4.One end of said iron core 2 is arranged at electromagnet 1 inside, and the other end connects with die arm 4, and iron core 2 is provided with back-moving spring 3, and this back-moving spring 3 is pressed and is located between electromagnet 1 and the die arm 4.
During work, operator's touch switch, give electromagnet 1 signal, electromagnet 1 is started working, iron core 2 in the electromagnet 1 moves upward, on draw the termination of the die arm 4 that connects with it to move upward, the other end of the last die 6 that connects on the die arm 4 moves downward, with following die 5 blades engagement, cut off cloth; Back-moving spring pushes away for 3 times, and die arm 4 returns initial position.
