Summary of the invention
In view of this, be necessary, a kind of automatic thread trimming device that can increase work efficiency is provided at the problems referred to above.A kind of sewing machine automatic thread trimming device, comprise motor, the stationary knife seat, stationary knife, the moving knife seat, moving knife, rotating shaft, described moving knife seat is connected with the stationary knife seat is vertical, described motor is arranged on an end of stationary knife seat and moving knife seat, described moving knife seat has axis hole, described rotating shaft is passed axis hole and is connected with motor, the other end of described stationary knife seat is provided with the stationary knife groove, described stationary knife is fixed in the stationary knife groove, and the other end of described moving knife seat is provided with the moving knife groove, and described moving knife groove and stationary knife groove are communicated with, described moving knife is fixed in the rotating shaft, and be positioned at the moving knife groove, under the idle situation of cutting facility, the angle of moving knife and stationary knife is 90 degree.
Preferably, described stationary knife seat is provided with stationary knife and regulates pad, and described stationary knife is regulated pad and is fixed on the stationary knife seat by screw.
Preferably, described rotating shaft is provided with moving knife and regulates pad, and described moving knife is regulated pad and is fixed in the rotating shaft by nut.
Preferably, described rotating shaft is provided with flexible member, and described flexible member is used to compress moving knife.
Preferably, described motor comprises forces turning cylinder, coil component spring, angle control rod, elastic gum, and described elastic gum has the fluting of 90 degree, is with silica gel sheath on the described angle control rod, one end of described coil component spring is fixed on the angle control rod, and the other end is fixed on the casing.
When the needs trimming, user's right crus of diaphragm touches the trimming switch, and 90 degree are rotated in the corresponding control rotating shaft of motor, and moving knife contacts with stationary knife moment and cuts off the end of a thread, and moving knife is got back to original position then.Above-mentioned sewing machine automatic thread trimming device can disposable automatic shearing, has not only reached the effect of at any time the end of a thread being cut off according to user's hope, makes whole operation to link up, and has reduced user's workload, has improved operating efficiency simultaneously.
Description of drawings
Fig. 1 is the front schematic view of cutting facility.
Fig. 2 is the schematic rear view of cutting facility.
Fig. 3 is the schematic diagram of motor.
The specific embodiment
See also Fig. 1 and Fig. 2, cutting facility comprises motor 1, stationary knife seat 2, stationary knife 4, moving knife seat 3, moving knife 5, rotating shaft 6.Moving knife seat 3 and 2 vertical connections of stationary knife seat, motor 1 is arranged on an end of stationary knife seat 2 and moving knife seat 3.Moving knife seat 3 has axis hole, and rotating shaft 6 is passed axis hole and is connected with motor 1.The other end of stationary knife seat 2 is provided with the stationary knife groove, and stationary knife 4 is fixed in the stationary knife groove.The other end of moving knife seat 3 is provided with the moving knife groove, and moving knife groove and stationary knife groove are communicated with.Moving knife 5 is fixed in the rotating shaft 6, and is positioned at the moving knife groove.When cutting facility was not worked, the angle of moving knife 5 and stationary knife 4 was 90 degree.
Also be provided with flexible member 61 (for example spring) in the rotating shaft 6, flexible member 61 is used to compress moving knife 5, so that shear more abundant.
In use, stationary knife seat 2 is fixed on the overlock machine housing, connects power supply then.When the needs trimming, the user sends trimming signal (flipping the trimming switch with right crus of diaphragm), and 90 degree are rotated in the corresponding control rotating shaft 6 of motor 1, and moving knife 5 contacts with 4 moments of stationary knife and cuts off the end of a thread, and moving knife 5 is got back to original position then.
Fig. 3 is the schematic diagram of motor 1.Motor 1 comprises forces turning cylinder 11, coil component spring 13, angle control rod 12, elastic gum 14.Elastic gum 14 has the fluting of 90 degree.Be with silica gel sheath on the angle control rod 12.One end of coil component spring 13 is fixed on the angle control rod 12, and the other end is fixed on the casing.
When motor 1 is connected power supply and is received the trimming signal, motor 1 control angle control rod 12 rotates, and just can run into elastic gum 14 when 12 rotations 90 of angle control rod are spent, because be with silica gel sheath on the angle control rod 12, so this collision process noise is little, shake little.Angle control rod 12 is pulled original position under the elastic force effect of coil component spring 13 then.
Above-mentioned sewing machine automatic thread trimming device has following advantage:
1, in the energising of the moment of trimming, use power 30W, be in power down mode during the non-trimming, no power consumption, electricity consumption every day 0.15KW/H, but about power saving 3 degree.
2, trimming locality specific, trimming process are in visual range, and the employee can free adjustment trimming length, reduce the waste of line.Compare with existing " pneumatic thread cutter ", each trimming can be saved over-lock seam 4cm at least.Through measuring 4 long line over-lock seam of the one section 4cm length that draws a straight line that stretches fully is 120cm, an overlock machine was operated at full capacity and is approximately broken 1000-2000 time in one day, the average line that can save 2000-3000 rice in a day of overlock machine of above-mentioned sewing machine automatic thread trimming device has been installed, and the overseam circuit is short more, the trimming frequency is high more, and it is obvious more to economize the line effect.
3, above-mentioned sewing machine automatic thread trimming device has been installed after, the parking stall work efficiency can improve 30%-40% than traditional disconnection manner; Improve 20% than pneumatic thread cutter.Even unit price of piecework downward modulation 10%, employee's income still can improve more than 10%, and the annual staff trimming expense of saving is more than 50%.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
