Abstract
Disclosed is a sewing machine feeding device, which comprises a driving rod, a main feeding rod, a differential feeding rod and two positioning limited adjusting rods. One end of the driving rod is provided with a shaft hole connected with a crank shaft, while the other end is provided with an overpass position to connect with the main feeding rod and the differential feeding rod; two raised blocks with adjusting slots are arranged on the overpass position; one end of the main feeding rod is erected on the overpass position, while a main tooth row is arranged on the front of the other end of the main feeding rod; one end of the differential feeding rod is erected on the overpass position, while a differential tooth row corresponding to the main tooth row is arranged on the front of the other end of the differential feeding rod; the two positioning limited adjusting rods are respectively connected between one adjusting slot and the main feeding rod, and between the other adjusting slot and the differential feeding rod. The utility model can adapt to all kinds of stretching fabric and will not generate waves and wrinkles in sewing.
Description
The utility model is relevant a kind of Feeding device of sewing machine.
Habit formula Feeding device of sewing machine generally as shown in Figure 1, comprise that mainly a drive bar a and a feeding rod b who is driven thereof form, wherein the front end of this feeding rod b has charging tooth row b1, and the bar end links with drive bar a, this drive bar a side is provided with the projection c that adjusts ditch c1 and revolves the lock positioning for a gag lever post d and be linked to follower arm b, change the distance of follower arm advance and retreat with the difference of gag lever post d latched position, reach the control sewing needle gage purpose of thickness at interval.
Though but its combination can reach the function that above-mentioned thickness is adjusted, but there is shortcoming in the design, the tooth row b1 that only connects single integral body as follower arm b, and the follower arm that has only single adjustment spacing, can't adjust differential ratio, so even when facing telescopic distributor, mixed up car pin thickness at interval, but because of the problem of the institute of cloth tool telescopic resilience own, still can make thread be the wave wrinkle, and influence car goods matter.
Because the above-mentioned existing shortcoming of Feeding device of sewing machine structure of commonly using, the purpose of this utility model is to provide a kind of and has differential adjustment, can not produce when enabling to adapt to various different telescopic distributor, sewing the Feeding device of sewing machine of wave wrinkle.
For reaching above-mentioned purpose, the utility model provides a kind of Feeding device of sewing machine, it is characterized in that: comprising:
One drives bar, and the one end is provided with the axis hole that links bent axle, and end is provided with amphi-position to link main feeding rod and differential feed bar in addition, locates to be provided with two in amphi-position and has the projection of adjusting groove;
One main feeding rod, one end are set up in aforementionedly amphi-position to be gone up, and holds the place ahead to be provided with main tooth row in addition;
One differential feed bar, one end are set up in equally aforementionedly amphi-position to be gone up, and holds the place ahead to be provided with the differential tooth row relative with main tooth row in addition; And
Two spacing adjusting levers are connected with respectively between adjustment groove and the main feeding rod and between another adjustment groove and the differential feed bar.
Described Feeding device of sewing machine, it is characterized in that: this main feeding rod and differential feed bar are to be arranged side by side, all establish shape prong behind its bar and all be set up in and drive the going up on the cross bar that is provided with of bar amphi-position, the projection that tool is adjusted groove is to be divided into amphi-position both sides respectively to should main feeding rod and differential feed bar.
Feeding device of sewing machine of the present utility model, decapacitation adjust main feeding rod walk apart from and change outside the thickness of sewing gap more visual various different cloth telescopic resiliences and adjust the differential feed bar, and reach the smooth-going practical purpose that can not produce the wave wrinkle of sewing.
In sum, the utility model makes Sewing machines really except that having general car pin thickness apart from adjusting, more can do suitable differential charging adjustment in the face of various different cloth telescopic resiliences, the smooth-going wave wrinkle that can not produce when making sewing, and effectively improve the quality of making thing.
For detail knowledge structure of the present utility model forming, lift the utility model now than specific embodiment, and cooperate graphic being described as follows:
Concise and to the point graphic explanation:
Fig. 1: for practising the three-dimensional exploded view of formula Feeding device of sewing machine structure.
Fig. 2: be three-dimensional exploded view of the present utility model.
Fig. 3: be the stereo appearance figure of the local combination of the utility model.
Fig. 4: be combination view of the present utility model.
Fig. 5: be the schematic diagram of the differential adjustment of the utility model tool.
Shown in Fig. 2,3,4, Feeding device of sewing machine of the present utility model, it mainly comprises: one drives bar 1, one main feeding rod 2, a differential feed bar 3, and 41,42 compositions of two spacing adjusting levers, wherein
One drives bar 1, and the one end is that axis hole 11 is driven to link bent axle (figure does not show), and end is provided with amphi-position 12 linking main feeding rod 2 and differential feed bar 3 in addition, in 12 place, both sides amphi-position and establish respectively and have the projection 14 and 15 of adjusting groove 141,151.
One main feeding rod 2, one end are established 21 of shape prongs on an aforementioned cross bar 121 of 12 amphi-position, and hold the place ahead to be provided with main tooth row 22 in addition.
One differential feed bar 3, one end are established shape prong 31 equally and also are set up on aforementioned 12 the cross bar 121 amphi-position, and hold the place ahead to be provided with the differential tooth row 32 relative with main tooth row 22 in addition; And
Two spacing adjusting levers 41,42, two ends tool combination bore 43 are mounted on respectively to be adjusted between groove 141 and main feeding rod 2 stage casings and adjustment groove 151 and differential feed bar 3 stage casings.
During its combination, shown in Fig. 2,3, this main feeding rod 2 and differential feed bar 3 are to be and to establish shape, and tool is adjusted the projection the 14, the 15th of groove 141,151, is divided into 12 both sides amphi-position, should main feeding rod 2 and the adjustment of the advance and retreat spacing of differential feed bar 3 to link 41,42 pairs of this two spacing adjusting levers respectively.
See also shown in Fig. 3,4,5, its structure is because of being provided with main feeding rod 2 and differential feed bar 3 during enforcement, and dividing be linked in the projection 14,15 by two spacing adjusting levers 41,42, so when driving the bar action, can make main feeding rod 2 and differential feed bar 3 interlocks after being adjusted, ask in both to produce the different differential ratios that advance.
More specifically, the utility model is if mat is transferred spacing adjusting lever 41 in the lock-bit of adjusting groove 141, can change the thickness of thread spacing, and mat is transferred spacing adjusting lever 42 in the lock-bit of adjusting groove 151, and differential adjustment can make sewing the time, make and adjust because of the different advance and retreat speed that obtain best fit of cloth, can obtain very smooth-going good quality so when in the face of telescopic distributor, make the thread that comes, be easy to produce the shortcoming appearance of wave wrinkle when not having habit formula structure sewing fully by the utility model institute car.
In sum, the utility model makes Sewing machines really except that having general car pin thickness apart from adjusting, more can do suitable differential charging adjustment in the face of various different cloth telescopic resiliences, the smooth-going wave wrinkle that can not produce when making sewing, and effectively improve the quality of making thing.
