The specific embodiment:
See also shown in Fig. 1,2, the present invention includes: a swing component 1, one first moving part 2 that driven by aforementioned swing component 1, one is subjected to second moving part 3 of aforementioned first moving part 2 transmissions, one the 3rd moving part 4 that articulates with aforementioned first and second moving part 2,3, one is subjected to the 4th moving part 6 and of aforementioned second moving part 3 transmissions to be subjected to the power transmission shaft 7 of aforementioned the 4th moving part 6 transmissions with the guiding mechanism 5, of aforementioned the 3rd moving part 4 windings.Interlock by the rear differential feed drive mechanism 10 of Sewing machines is provided with a power transmission shaft 8.This power transmission shaft 8 can transmission the present invention campaign, and then drives front transfer teeth 9 motions of Sewing machines machine, and it is fast or slowly to control the speed of sewing cloth feeding; Simultaneously, each member of this front differential feeding, regulating and controlling mechanism allows the dealer be easy to processing and assembling.
Have an axial region 11 on the above-mentioned swing component 1, this axial region 11 is able to the power transmission shaft 8 that winding one is connected with rear differential feed drive mechanism 10, after power transmission shaft 8 and axial region 11 windings, can utilize locking part 12 lockings.This axial region 11 is connected with a swing arm 13, has a pair of articulated section 14 on this swing arm 13, is provided with an axle 15 and passes aforesaid articulated section 14 and articulated first moving part 2.This first moving part 2 is a coupled arm 2l, and these coupled arm 21 two ends respectively have an articulated section 22,23, and this articulated section 22 is provided with axle 15 and is able to articulate with the articulated section 14 of above-mentioned swing component 1; After articulated section 22 and axle 15 windings, can utilize a locking part 25 lockings, after this locking part 25 unclamps, can adjust first moving part 2 and axle 15 winding angles, to adjust the amplitude of oscillation size that swing component 1 drives first moving part 2.Another articulated section 23 is provided with axle 24 and is articulated second and third moving part 3,4.This second moving part 3 is a coupled arm 31, and these coupled arm 31 two ends respectively have an articulated section 32,33, and this articulated section 32 is provided with axle 24 and is able to articulate with the articulated section 23 of first moving part 2, another articulated section 33 then with 6 windings of the 4th moving part.The 3rd moving part 4 is a coupled arm 41, and these coupled arm 41 two ends respectively have an articulated section 42,43, and this articulated section 42 is provided with an axle 44, and this axle 44 is able to winding one guiding mechanism 5; Another articulated section 43 is connected on the axle 24, and is connected with first and second moving part 2,3.This guiding mechanism 5 includes a counterweight 51, a connecting axle 52 and a pulling piece 53.Has plural group connecting part 511 on this counterweight 51, after this arbitrary group connecting part 511 and axle 44 windings, can utilize a locking part 54 lockings, another group connecting part 511 is the aforesaid connecting axle 52 of winding then, has a caulking groove 521 on this connecting axle 52, the aforesaid pulling piece 53 of these caulking groove 521 interlockings.When pulling piece 53 is pulled, can drive counterweight 51 and the 3rd moving part 4 adjusts state.The 4th moving part 6 is a coupled arm 61, these coupled arm 61 two ends respectively have a junction 62,63, the pivot joint that this connecting portion 62 is connected with an axle 64 and second moving part 3 33 does not articulate, another connecting portion 63 then connects a power transmission shaft 7, these power transmission shaft 7 one ends then with front transfer teeth 9 windings, after power transmission shaft 7 is subjected to 6 transmissions of the 4th moving part, can drive front transfer teeth 9 reciprocating motions, sewing cloth can be continued to feed in car pin below sewing to reach.In this way, use and constitute a brand-new front differential feeding, regulating and controlling mechanism.
See also Fig. 3-1～Fig. 3-3, at first, when guiding mechanism 5 is not pulled, this power transmission shaft 8 is subjected to promptly to drive swing component 1 after the transmission of rear differential feed drive mechanism (not shown), the swing arm 13 of this swing component 1 can be a swing state, promptly drive 2 actions of first moving part this moment, when first moving part 2 is driven, drive 3 actions of second moving part immediately, also drive 6 actions of the 4th moving part under 3 actions of second moving part simultaneously, after the 4th moving part 6 was driven, this power transmission shaft 7 was also along with action, but and then transmission front transfer teeth 9 action, the cloth of preparation sewing can be fed in car pin below sewing.Because when guiding mechanism 5 was not adjusted, the angle angle that the 3rd moving part 4 and second moving part are 3 was bigger, therefore the 4th moving part 6 is also bigger by the amplitude of oscillation of transmission, and front transfer teeth 9 is also very fast by the speed of transmission campaign relatively.When the pulling piece 53 of guiding mechanism 5 is pulled, cause the angle angle of 3 of the 3rd moving part 4 and second moving parts to diminish, or shown in Fig. 4-1 and Fig. 4-2, when the 3rd moving part 4 and second moving part 3 are parastate, the 4th moving part 6 is more small by the amplitude of oscillation of transmission, and the speed that preceding relatively title send tooth 9 to be moved by transmission is also slower.
Moreover, the present invention is at the angle angular dimension of adjusting between the 3rd moving part 4 and second moving part 3, with reach front transfer teeth 9 quick actions or slow outside, in the front differential feeding, regulating and controlling mechanism motion process, still can directly pull pulling piece 53 and adjust, allow front transfer teeth 9 in motion process, carry out the fast or slow adjustment of feeding speed.
See also shown in Figure 5, after the present invention is installed on Sewing machines 101 inside, and on the cylinder 102 of Sewing machines 101, dispose one and adjust panel 103, after utilizing locking part 104 to pass the motion hole 106 of adjustment button 105 and adjustment panel 103 simultaneously, get so that pulling piece 53 locks, the mobile button 105 of adjusting can drive the speed adjustment that pulling piece 53 is done front transfer teeth 9 to the operator on the panel 103 in adjusting.
