The course of work of the utility model：
7 cloth feed amount of interior feed dog is in the same size with 42 cloth feed amount of feed mechanism, and outer crank of tooth frame 8 can sent outside
It is swung on 17 small column 22 of cloth crank, by the adjusting bolt 27 on cloth feeding crank outside turn 17 sliding block 31 can be realized in rectangle
Movement in sliding slot 24, in the case where 42 cloth feed amount of feed mechanism is constant, when sliding block 31 is close to 1 center of cloth pushing shaft, outside
The swing angle that cloth feeding crank 17 passes to outer crank of tooth frame 8 becomes smaller, so as to which the oscillating quantity of outer retainer 10 be driven to reduce, outer work feed
12 cloth feed amount of tooth reduces, and forms the form that outer 12 cloth feed amount of feed dog is less than interior 7 cloth feed amount of feed dog at this time, and sewing is formed and is drawn
The effect of stretching.When sliding block 31 is away from 1 center of cloth pushing shaft, the swing angle that outer cloth feeding crank 17 passes to outer crank of tooth frame 8 becomes larger,
So as to which the oscillating quantity of outer retainer 10 be driven to increase, outer 12 cloth feed amount of feed dog becomes larger, and it is big to form outer 12 cloth feed amount of feed dog at this time
In the form of interior 7 cloth feed amount of feed dog, the effect shunk is formed to sewing.
Pass through the turn of adjusting bolt 27 on external cloth feeding crank 17, you can feed dog 7 and outer work feed in convenient realization
The differential feed of tooth 12, by the different position of sliding block 31, it can be achieved that different differential ratios.
Referring to Figure 12：" stretching " feeding state：When sliding block is located at outer work feed slide crank slot the top (Fig. 7), cloth pushing shaft
Give interior crank of tooth frame the swing power source synchronous with the output of outer cloth feeding crank simultaneously, interior crank of tooth frame is connected directly between with interior retainer
Together, feed dog swing in drive, the oscillating quantity on interior retainer is consistent with the oscillating quantity that cloth pushing shaft exports, and outer retainer is bent
The oscillating quantity of handle passes to the long connecting rod one for connecting outer crank of tooth frame by the long connecting rod two connected on outer cloth feeding crank, so as to band
The swing of outer crank of tooth frame is moved, since sliding block is in above sliding slot, so distance of its center apart from outer work feed crank center
Become smaller, so that the oscillating quantity that outer cloth feeding crank passes to outer crank of tooth frame reduces, and the cloth feed amount of outer feed dog becomes smaller, inside send
Dog cloth feed amount is more than outer feed dog cloth feed amount, sews and generates the effect stretched to cloth.
Referring to Figure 13：" synchronization " feeding state, when sliding block is located at outer work feed slide crank slot centre position (Fig. 8), work feed
Axis gives interior crank of tooth frame the swing power source synchronous with the output of outer cloth feeding crank simultaneously, and interior crank of tooth frame is directly connected to interior retainer
Together, feed dog swing in drive, the oscillating quantity on interior retainer is consistent with the oscillating quantity that cloth pushing shaft exports, and outer retainer is bent
The oscillating quantity of handle passes to the long connecting rod one for connecting outer crank of tooth frame by the long connecting rod two connected on outer cloth feeding crank, so as to band
The swing of outer crank of tooth frame is moved, when sliding block is among sliding slot, distance of its center apart from outer work feed crank center and outer tooth
Distance of the frame crank center apart from long connecting rod one is equal, so that outer cloth feeding crank passes to the oscillating quantity of outer crank of tooth frame not
Become, the cloth feed amount of outer feed dog is constant, and interior feed dog cloth feed amount is consistent with outer feed dog cloth feed amount, is at this time synchronous feeding.
Referring to Figure 14：" contraction " feeding state, when sliding block is located at outer work feed slide crank slot lower position (Fig. 9), work feed
Axis gives interior crank of tooth frame the swing power source synchronous with the output of outer cloth feeding crank simultaneously, and interior crank of tooth frame is directly connected to interior retainer
Together, feed dog swing in drive, the oscillating quantity on interior retainer is consistent with the oscillating quantity that cloth pushing shaft exports, and outer retainer
The oscillating quantity of crank passes to the long connecting rod one for connecting outer crank of tooth frame by the long connecting rod two connected on outer cloth feeding crank, so as to
The swing of outer crank of tooth frame is driven, since sliding block is in below sliding slot, distance of its center apart from outer work feed crank center is big
In the distance of outer crank of tooth frame centre distance long connecting rod one, so that outer cloth feeding crank passes to the oscillating quantity of outer crank of tooth frame
Become larger, the cloth feed amount of outer feed dog becomes larger, and interior feed dog cloth feed amount is less than outer feed dog cloth feed amount, sews and generates contraction to cloth
Effect.
The above is only the preferred embodiment of the utility model, is not intended to limit the protection of the utility model
