Abstract
Provided is a novel thread trimming mechanism of an industrial lockstitch sewing machine. The thread trimming mechanism is driven by an electromagnet which is directly connected to the tooth bar in a rack-and-pinion mechanism, the thread trimming part is a scissors mechanism, the moving knife of the scissors mechanism abuts against the cam fixed on the gear shaft, the electromagnet directly transmits power to the cam via the rack-and-pinion mechanism, and the cam presses the stationary knife down to complete thread trimming. The whole running process is clear and smooth, and the thread trimming operation is stable and reliable.
Description
Affiliated technical field
The utility model belongs to field of mechanical technique, relates to a kind of thread cutting mechanism of flat seam machine.
Background technology
The various thread cutting mechanisms of Sewing machines all connect together with presser foot lifter mechanism at present, a shared solenoid actuated, and the action of electromagnet at first acts on presser foot lifting device, by connector action is delivered to cutting facility simultaneously and comes trimming.Traditional mechanism's more complicated is not easy dismounting, and part is not easy processing.
Summary of the invention
Link in order to overcome existing thread cutting mechanism and presser foot lifter mechanism, and complex structure, the defective that is difficult for installation and processes, the utility model provides a kind of novel thread cutting mechanism, and this mechanism structure is simple, easy for installation.
The technical scheme that its technical problem that solves the utility model adopts is: thread cutting mechanism of the present utility model comprises a trimming electromagnet, one cam, a pair of gear, tooth bar, the trimming cutting knife that one cover is made up of moving knife and stationary knife, on the industrial flat bed sewing machine frame, stationary knife is installed, moving knife is installed on the stationary knife by pin, can rotate around stationary knife simultaneously, forms one the trimming scissors with stationary knife.The handle of a knife of described moving knife links to each other with cam, and cam is fixed on vertical pivot one end, vertical pivot other end fixed gear, and described wheel and rack is meshed, and described tooth bar and trimming electromagnet core directly are hinged.
The beneficial effects of the utility model are, and are simple in structure, safe and reliable, do not link with presser foot lifter mechanism when work.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure chart of the present utility model.
1. electromagnet among the figure, 2. tooth bar, 3. gear, 4. vertical pivot, 5. cam, 6. moving knife, 7. stationary knife, 8. pin axle, 9. compression spring.
The specific embodiment
Tooth bar (2) and electromagnet (1) are by being connected, and electromagnet (1) is fixed on the frame, slides in the groove of tooth bar (2) on frame.Tooth bar (2) and gear (3) engagement, gear (3) is installed on the vertical pivot (4), vertical pivot (4) is mounted on the frame, the other end of vertical pivot (4) is fixed with cam (5), the outer rim of cam (5) is close to the moving knife (6) in the scissors-type cutting knife, moving knife (6) rotates around the pin axle (8) that is fixed on the stationary knife (7), stationary knife (7) is fixed on the frame, one compression spring (9) is arranged between stationary knife (7) and the moving knife (6), under the effect of compression spring (9), moving knife (6) handle of a knife tightly leans against on the cam (5).
When needing trimming, electromagnet (1) energising adhesive, tooth bar (2) is done horizontal movement under the effect of electromagnet (1), because tooth bar (2) and gear (3) engagement, the rotation of the motion driven gear (3) of tooth bar (2).Gear (3) is fixed on the vertical pivot (4), thereby vertical pivot (4) is rotated, and vertical pivot (4) drives cam fixed thereon (5) again and rotates.Rotate thereby promote moving knife (6), make the moving knife blade closed mutually, thereby finish the trimming action with the stationary knife blade.
Claims (2)
1. an industrial flat bed sewing machine thread cutting mechanism comprises an electromagnet, a cam, and a pair of gear, tooth bar, the trimming cutting knife that a cover is made up of moving knife and stationary knife, it is characterized in that: described electromagnet and tooth bar are directly hinged, rack and pinion engagement transmission power.
2. thread cutting mechanism according to claim 1 is characterized in that: on the industrial flat bed sewing machine frame stationary knife is installed, moving knife is installed on the stationary knife by pin, can rotate around stationary knife simultaneously, forms one the trimming scissors with stationary knife.
