Abstract
The invention discloses a cloth-handling mechanism with a unidirectional rotated shearing force. The cloth-handling mechanism comprises a cloth-handling wheel, wherein two sides of the cloth-handling wheel are respectively provided with a ratchet wheel for driving the cloth-handling wheel to rotate unidirectionally and preventing the cloth-handling wheel from rotating oppositely; an accommodation cavity for accommodating roller pins is formed between the teeth of the ratchet wheel and the cloth-handling wheel; the accommodation cavity is narrowed gradually clockwise or anticlockwise; the distance between the roller pins is greater than the narrowest width of the accommodation cavity; a compression spring is arranged between the roller pins and the teeth at the wider side of the accommodation cavity; and when the acting force of the roller pins disappears, the roller pins return the original position due to the action of the force of the compression spring. In the cloth-handling mechanism, by the size relationship of the diameter of the roller pins and the width of the accommodation cavity formed between the teeth and the cloth-handling wheel, the cloth-handling wheel only can rotate in a single direction; and a group of ratchet wheels and roller pins are arranged on the other side in the same direction for braking the opposite rotation of the cloth-handling wheel, therefore, the cloth-handling mechanism has the advantages of reliable unidirectional rotation and low cost, and is suitable for being used as the cloth-handling mechanism of sewing machines.

In the accompanying drawing: 1, pedestal; 2, lid; 3, straight pin; 4, cloth-dragging wheel; 5, ratchet; 6, power wheel; 7, pull bar; 8, teeth; 9, cavity volume; 10, needle roller; 11, compression spring; 12, rotating shaft; 13, blind hole.
The specific embodiment
Below in conjunction with embodiment shown in the drawings the present invention is made following detailed description:
As accompanying drawing 1, shown in accompanying drawing 2 and the accompanying drawing 3, the mop mechanism of shear force one-directional rotation of the present invention comprises pedestal 1 and lid 2, form a host cavity between pedestal 1 and the lid 2, run through in the host cavity and be provided with a straight pin 3, the two ends of straight pin 3 are installed in respectively on pedestal 1 and the lid 2, the rotatable cloth-dragging wheel 4 that is provided with on the straight pin 3, the both sides of cloth-dragging wheel 4 have circular accepting groove respectively, correspondence contains a ratchet 5 in each accepting groove, ratchet 5 near pedestal 1 is fixedly installed on the pedestal 1, ratchet 5 near lid 2 is fixed on the rotatable power wheel 6 that is arranged on the straight pin 3, power wheel 6 is provided with one can spur the pull bar 7 that it rotates around straight pin 3, each ratchet 5 all with cloth-dragging wheel 4 setting that rotates, each ratchet 5 has a plurality of teeth 8, form a cavity volume 9 between the cell wall of each adjacent two teeth 8 and accepting groove, each cavity volume 9 is all narrowing down on clockwise or counterclockwise direction gradually, all be provided with needle roller 10 in each cavity volume 9, the diameter of needle roller 10 is greater than the width at narrow place of cavity volume 9, needle roller 10 and between the teeth 8 of width greater than an end of its diameter of the cavity volume 9 at its place, be provided with compression spring 11, two ratchets 5 are provided with in the same way, it is one uncovered that the top of pedestal 1 has had, part cloth-dragging wheel 4 is given prominence to outside from uncovered, and, the outer peripheral face of cloth-dragging wheel 4 is rough reticulate pattern, and produce bigger frictional force between the former cloth so that transmit former cloth, pull bar 7 is hinged on the edge of power wheel 6 by a rotating shaft 12, and rotating shaft 12 parallels with the axial line of power wheel 6, offer blind hole 13 on the teeth 8 of the width of cavity volume 9 greater than an end of its diameter, an end of compression spring 11 is fastened in the blind hole 13.
As shown in Figure 3, this mop mechanism back and forth spurs power wheel 6 by pull bar 7 in same angle, when cloth-dragging wheel 4 gives the power of needle roller 10 greater than compression spring 11 for the power of needle roller 10, cloth-dragging wheel 4 can rotate along the direction of arrow shown in the figure, when the active force of 10 pairs of cloth-dragging wheels 4 of needle roller disappears, when needle roller 10 that be subjected to figure in direction of arrow equidirectional the power sum less than be subjected to figure in during the rightabout power sum of the direction of arrow, cloth-dragging wheel 4 stops operating, and, make cloth-dragging wheel 4 that reciprocal rotation can not take place owing to be installed in the effect of ratchet 5 and needle roller 10 on the pedestal 1.
Because the requirement of the mop mechanism on the Sewing machines is merely able to folk prescription and advances former cloth to ground, and can not move back the phenomenon of cloth, the mop mechanism of shear force one-directional rotation of the present invention can realize a kind of like this function exactly.
The present invention by ingenious design needle roller 10 diameter and teeth 8 and cloth-dragging wheel 4 between the magnitude relationship of width between the two of the cavity volume 9 that forms, make that cloth-dragging wheel 4 is merely able to upwards rotate at folk prescription, and the effect of power wheel 6 is caused cloth-dragging wheel 4 rotate for fear of foreign steamer, be provided with the structure of equidirectional one group of ratchet 5 and needle roller 10 again at opposite side, unidirectional rotation is reliable, cheap, be convenient to safeguard that the mop mechanism that is suitable as Sewing machines uses.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
