When the wire separating hook seat 3 drives the wire separating hook 4 to swing left and right relative to the upright post 100, the hook 41 and the convex part 121 can be propped against each other, even if the wire distributing opening 6 is closed. When the wire separating hook seat 3 drives the wire separating hook 4 to swing left and right relative to the upright post 100, the hook 41 can be further away from the convex part 121, even if the wire distributing opening 6 is opened.
The position of the branching hook 4 on the branching hook seat 3 can be adjusted left and right, so that the opening size can be adjusted when the wiring opening 6 is opened, and the branching amount can be controlled.
The position of the branching hook 4 is adjusted in the following way: as shown in fig. 3, one of the lower part of the wire-dividing hook 4 and the upper part of the wire-dividing hook seat 3 is provided with an adjusting groove 42 extending in the left-right direction, and the other is provided with a connecting hole, and the second fastening piece 7 passes through the connecting hole and the adjusting groove 42 to fixedly connect the wire-dividing hook 4 and the wire-dividing hook seat 3. When the second fastening piece 7 is loosened, the wire separating hook 4 can move left and right relative to the wire separating hook seat 3 to adjust the position. After the branching hook 4 is adjusted in place, the second fastening piece 7 is screwed down, and the position of the branching hook 4 is locked. In this embodiment, the adjusting slot 42 is disposed on the branching hook 4, and the connecting hole is disposed on the branching hook seat 3.
As shown in fig. 2, the second seat plate 32 is provided with guide grooves 321 extending in the left-right direction, and the guide grooves 321 penetrate both left and right end surfaces of the second seat plate 32. The lower part of the branching hook 4 is provided with a positioning part 43 matched with the guide groove 321, and the positioning part 43 is positioned in the guide groove 321. When the wire separating hook 4 moves to the left and right with respect to the wire separating hook seat 3, the positioning portion 43 moves in the guide groove 321 along the length extending direction of the guide groove 321, thereby guiding the left and right adjustment of the wire separating hook 4.
As shown in fig. 8 and 11, a slot 201 is provided on the needle plate 200, a stop hook 122 is also provided on the bobbin 12, the stop hook 122 extends into the slot 201, and a wire outlet slot 8 is formed between the stop hook 122 and a side wall 201a of the slot 201. When the rotating shuttle assembly 1 rotates, the stop hook 122 can be attached to one side wall 201a of the slot 201, even if the slot 8 is closed. The rotating shuttle assembly 1 can also rotate to move the stop hook 122 away from the side wall 201a of the slot 201 even if the wire outlet slot 8 is opened.
The working principle of the branching mechanism is as follows:
when the rotating shuttle assembly 1 rotates, the shuttle shell 11 and the shuttle shaft 13 synchronously rotate to drive the branching cam 2 to synchronously rotate to drive the branching hook seat 3 to drive the branching hook 4 to swing left and right around the screw 5, in the process, the shuttle liner 12 rotates in the same direction under the drive of the shuttle shell 11 and the shuttle shaft 13, but the rotating speed of the shuttle liner 12 is lower than that of the shuttle shell 11 and the shuttle shaft 13.
When the bottom of the thread separating hook seat 3 contacts with the minimum stroke position 2a of the thread separating cam 2, the hook 41 of the thread separating hook 4 moves away from the convex part 121 of the shuttle 12, so that the thread opening 6 is opened, as shown in fig. 6 to 8. At this time, the stop hook 122 on the bobbin bladder 12 is attached to the side wall 201a of the slot 201, so that the slot 8 is closed. The branching starts, and the upper wire comes out from the wire outlet 6 and then goes to the wire outlet groove 8.
When the bottom of the thread separating hook seat 3 contacts with the maximum travel position 2b of the thread separating cam 2, the hook 41 of the thread separating hook 4 is close to the convex part 121 of the shuttle container 12, so that the thread outlet 6 is closed, as shown in fig. 9 to 11. The shuttle bladder 12 reversely rotates under the action of the branching hook 4, so that the stop hook 122 on the shuttle bladder 12 is far away from the side wall 201a of the slot 201, and the wire outlet slot 8 is opened. The upper line brings out the bottom line from the outlet groove 8, and the branching is finished.
Before the sewing machine works, the branching time of the sewing machine can be adjusted by adjusting the angle of the branching cam 2 relative to the bobbin case 11, and the branching amount of the sewing machine can be adjusted by adjusting the position of the branching hook 4 on the branching hook seat 3.
In addition, it should be noted that the specific embodiments described in the present specification may vary from part to part, from name to name, etc., and the above description in the present specification is merely illustrative of the structure of the present utility model. All equivalent or simple changes of the structure, characteristics and principle according to the inventive concept are included in the protection scope of the present patent.
