In a differential feed sewing machine which is capable of horizontal reciprocating motion to the main feed dog 5, one end of the feed shaft 9, which is swingably connected to the main feed dog 5, is attached to the main feed adjustment link 8. The main feed adjustment link 8 is connected to the sewing machine main shaft 1 via the eccentric cam 6, and the main feed adjustment link 8 is connected to the sewing machine main shaft 1 via the eccentric cam 6, and the other end is used to adjust the stroke of the horizontal reciprocating movement of the main feed dog 5. It is rotatably mounted on the sewing machine frame and is connected to a main feed adjuster 11 having a main feed adjustment dial 12, and is also swingable to give horizontal reciprocating motion to the sub feed dog 20. A differential feed shaft 32 connected to the feed shaft 9 is swingably connected to the feed shaft 9, and the differential feed shaft 32 has a mechanism that adjusts the stroke amount of the horizontal reciprocating motion of the sub-feed dog 20 by controlling the amount of swing thereof. In order to do this, a lever 23 which is rotatably attached to the sewing machine frame and can be fixed by a sub-feed adjustment knob 24 is connected, and the main feed adjuster 11 and lever '-23 are connected to each other by a par 40. A feed dog drive mechanism that is rotatably connected. 2. The feed dog drive mechanism according to claim 1, wherein the par 40 is rotatably connected to the lever 23' through an elongated hole 401 formed in the par 40. 3 Attach the main feed dog 5 to the main feed base 3, and attach the main feed dog 5 to the main feed base 3.
is connected to the main shaft 1 via an eccentric cam 2 and a slide block 4, and the main shaft 1 is connected to a main feed adjustment link 8 via another eccentric cam and an eccentric cam rod 7. The link 8 is attached to the feed shaft 9, which is fixed to the arm 91. 92. The feed dog drive mechanism according to claim 1 or 2, wherein the feed dog drive mechanism is swingably connected via a shaft 92. 4. The sub-feed dog 20 is attached to the main feed base 3, and the sub-feed base 21 is attached to the main feed base 3 so that it can move relative to the main feed base 3 in the horizontal direction, and the sub-feed base 21 is fixed to the differential feed shaft 32. are swingably connected via the arm 32□,
Further, the differential feed shaft 32 and the feed shaft 9 are connected by a link 3 with an arm 321 fixed to the former and an arm 93 fixed to the latter.
1. The feed dog drive mechanism according to claim 1.2 or 3, wherein the feed dog drive mechanism is connected to each other by being rotatably connected through the utility model registration claim 1.2 or 3. 5. Groove 11.5 in main feed adjuster 11 with main feed adjustment dial 12. and one end of the main feed adjustment link 8 is movably connected to the groove 11□ via a top 1o rotatably attached to the groove 11□. The feed dog drive mechanism according to any one of Items 1 to 4. - The 6 lever 23 is rotatably attached to the sewing machine frame at approximately the center thereof, and one end thereof is connected to the sub-feed adjustment knob 24.
The other end of the lever 23 is fixed to a guide 25 attached to the sewing machine by a link 26, and one end of the lever 23 is rotated to approximately the center of the lever 28, which is rotatably attached to the sewing machine. The link 29 is rotatably connected to the other end of the lever 28 at one end thereof, and the arm 32 is fixed to the differential feed shaft 32 at the other end.
1. The feed dog drive mechanism according to any one of claims 1 to 5, which is a utility model registered, and is connected to one end of a link 31 via a link 31. 7 Main feed adjustment dial 12 and sub feed adjustment knob 24
The feed dog drive mechanism according to any one of claims 1 to 6, wherein the feed dog drive mechanism is arranged on the front side of the sewing machine.
