The specific embodiment

The utility model is a kind of granny rag machine (as shown in Fig. 1 to Fig. 4), and this granny rag machine is provided with a body frame 10 respectively in both sides, and wherein a body frame 10 bottoms are provided with a roller 11, and this roller 11 can roll on a desktop 12.

Roller 11 inboards are provided with first sprocket wheel 13, but first sprocket wheel, 13 transmissions, one chain 14, a rotating shaft 16 is established in transmission second sprocket wheel 15, the second sprocket wheels 15 inboards on the chain 14, and this rotating shaft 16 can drive to gear train 17 places.Single direction ratchet is established in a gear inside in the gear train 17, a belt pulley 18 is established in gear train 17 outsides, transmission one belt 19 on the belt pulley 18, this belt 19 can be for driving to another belt pulley 20 places, another belt pulley 20 can drive one 21, these axle 21 inboard polygonal axles 22 that drive, polygonal axle 22 end in addition extends to another body frame 10 inboards, polygonal axle 22 ends are arranged on another body frame 10 with circular shaft 23, what the polygonal hole of one inner tool was set on the polygonal axle 22 puts cloth cylinder 30, puts cloth cylinder 30 and makes for the material with big frictional force.

One back-up roller 40, be to be located at the appropriate intervals distance to put cloth cylinder 30 rear ends, the yardage roll of whole volume is positioned between cloth cylinder 30 and the back-up roller 40, and back-up roller 40 inside also are provided with polygonal axle 41 and extend to body frame 10 inboards respectively, and polygonal axle 41 outsides are established circular shaft 42 and are arranged on the body frame 10.

As Fig. 5, shown in Figure 6, in a side of putting cloth cylinder 30 and back-up roller 40 retainer ring 50 is set simultaneously, its inside is provided with circular hole 51, the diameter of circular hole 51 is greater than polygonal axle 2241 width, so that retainer ring 50 can be traversing on polygonal axle 2241, be provided with corresponding groove between 50 at the ring that is relatively fixed, place on the relative groove for a plectrum 60.

One servo motor 70 is arranged at a body frame 10 outsides, and a cross bar 71 is fixed on the plectrum 60 after laterally wearing servo motor 70 and body frame 10.

One Contraband shape inductor frame 80 which is provided with inductor, and this inductor frame 80 is arranged at a body frame 10 inboards, for the left and right position of induction cloth 90.Be provided with electric wire 81 between inductor frame 80 and the servo motor 70.In addition between relative body frame 10 and be positioned at inductor frame 80 and slightly be provided with a guide rod 91 in the place aheads, cloth 90 is derived being used for, and electronic cut-off knife 92 is set on the granny rag machine, be used for cloth 90 is cut into the large and small of proper area.

During use, as Fig. 1, Fig. 2, shown in Figure 4, in the utility model, desktop 12 front end places will be pushed into before the granny rag machine, because single direction ratchet is established in gear train 17 inside, cloth is put in not transmission this moment, and the operator need push down cloth 90 front ends, again the granny rag machine is retreated, roller 11 rubs on desktop 12, and first sprocket wheel, 13 driving chains 14, second sprocket wheel 15, rotating shaft 16, gear train 17, belt pulley 18, belt 19, belt pulley 20, axle 21, polygonal axle 22 are rotated, and rotates so that put cloth cylinder 30.Because of the cloth of whole volume is positioned over the place, top of

cloth cylinder

30 and 40 of back-up rollers, thus can drive the whole cloth of rolling up 90 rotations, to reach the self-feeding purpose.

Another characteristics of the present utility model are: when cloth 90 after set inductor responds to its left and right position on via inductor frame 80, when if left and right skew takes place in cloth 90, send a signal to servo motor 70, make cross bar 71 left and right traversing, plectrum 60 is stirred by cross bar 71, retainer ring 50 can be made put the synchronous left and right passing of cloth cylinder 30 and back-up roller 40, with left and right position from dynamic(al) correction cloth 90, reach the purpose of automatic opposite side, so that the cloth 90 after being cut by electronic cut-off knife 92 reaches the effect of neat and opposite side.The utility model can reach a people can be operated, but and the self-feeding and the automatic purpose of opposite side, use to make things convenient for the user.

The utility model is to utilize aforesaid structure, and by said apparatus, reaching a people can operate, and has the advantage of self-feeding and automatic opposite side concurrently, has obvious effect, meets novel patent requirement, so mention application in accordance with the law.
