Abstract
The invention relates to a feed dog swing mechanism of a sewing machine. The feed dog swing mechanism comprises a main transmission rod and a feed dog. The feed dog is arranged at one end of the main transmission rod and movably connected with the main transmission rod through a pin shaft. A cam mechanism is arranged on the main transmission rod and connected with a worm gear through a link rod, wherein the worm gear is arranged on the side face of the main transmission rod. The worm gear is in transmission connection with a worm arranged on the side face of the worm gear. According to the feed dog swing mechanism of the sewing machine, the feed dog can stably move, the service life is long, the maintenance cost is low, and the production cost is also reduced.
Description
Technical field
The present invention relates to Sewing machines field, relate in particular to a kind of cloth-feeding teeth of sewing machine swing mechanism.
Background technology
Sewing machines is a kind of machinery that cloth can be sewed up to splicing, and it has effectively substituted, and manual sewing clothes efficiency of past is slow, the inaesthetic defect of stitch.Sewing machines is pushed ahead cloth by the feed dog below board in tailoring cloth process, and in order to guarantee that feed dog can reciprocating motion, existing feed dog is all to drive the cam on feed dog drive link to realize motion by belt.Because belt easily skids and relaxes using after a period of time, affect feed dog swing, and such belt need to change, thereby increase cost of equipment maintenance.
Summary of the invention
Technical problem to be solved by this invention is that the cloth-feeding teeth of sewing machine swing mechanism that a kind of working stability and maintenance cost are low is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of cloth-feeding teeth of sewing machine swing mechanism, comprise main transmission bar and feed dog, described feed dog is arranged on main transmission bar one end, between by bearing pin, be flexibly connected, on described main transmission bar, be provided with cam mechanism, cam mechanism is connected with the worm gear that is arranged on main transmission bar side by link rod, and this worm gear is connected with the worm-drive that is arranged on its side.
Compared with prior art, usefulness of the present invention is: this cloth-feeding teeth of sewing machine swing mechanism can make the feed dog can stable motion, long service life, and maintenance cost is low, has also reduced production cost.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is cloth-feeding teeth of sewing machine swing mechanism structural representation of the present invention.
In figure: 1, main transmission bar; 2, feed dog; 3, bearing pin; 4, worm screw; 5, worm gear; 6, link rod; 7, cam mechanism.
the specific embodiment:
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of cloth-feeding teeth of sewing machine swing mechanism shown in Fig. 1, comprise main transmission bar 1 and feed dog 2, described feed dog 2 is arranged on main transmission bar 1 one end, between by bearing pin 3, be flexibly connected, on described main transmission bar 1, be provided with cam mechanism 7, cam mechanism 7 is connected with the worm gear 5 that is arranged on main transmission bar 1 side by link rod 6, and this worm gear 5 is in transmission connection with the worm screw 4 that is arranged on its side.
During use, drive worm gear 5 to rotate worm screw 4, worm gear 5 drives cam mechanism 7 to rotate by link rod 6, thereby drives main transmission bar 1 to move, and main transmission bar 1 drives feed dog 2 to move.
This cloth-feeding teeth of sewing machine swing mechanism can make the feed dog can stable motion, long service life, and maintenance cost is low, has also reduced production cost.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
