Specific implementation mode

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

As shown in Figures 1 and 2, which includes holder 10, the main shaft 20 on the holder 10, is connected at The driven wheel 30 of 20 one end of main shaft, set on 20 other end of main shaft and make connecting rod 40 that its top is fixedly connected with main shaft 20, The connector sleeve 50 that is rotatably connected with the bottom end of the connecting rod 40, the unilateral bearing 60 on the connector sleeve 50 and it is supported in the list The top of idler wheel 70 on bearing 60, the connecting rod 40 is connect with 20 bias of main shaft.The connector sleeve 50 is in the side far from idler wheel Equipped with a pull rod 90, the central shaft of the both ends of the pull rod 90 respectively with holder 10 and unilateral bearing 60 is rotatably connected, the holder A clamping screw 11 is also worn and is screwed on 10, which, should in being arranged with spring on the body of rod of 10 lower section of holder The bottom end of clamping screw 11 presses on pull rod 90, and height of the pull rod 90 relative to holder 10 is adjusted by the pressure of clamping screw 11 It is low, to reach the pressure for reconciling idler wheel 70 to cloth, the restoring force of the setting adjustment clamping screw 11 of spring.

The driven wheel 30 is connect by driving members such as belt or chains with the driving wheel on sewing machine.In use, this is actively Wheel rotation drives driven wheel 30 to rotate, and drives main shaft 20 to rotate by driven wheel 30, to make the top of connecting rod 40 around main shaft 20 Rotation, and then make the bottom end of connecting rod 40 that 50 swing of connector sleeve be driven to make 50 band of connector sleeve due to the setting of unilateral bearing 60 Dynamic idler wheel 70 discontinuously rotates in one direction always, and the direction is the side for promoting the cloth of sewing machine to be formed to rear side dilatory force To.By the setting of the mop wheel construction to processing the tractive force of cloth application backward on sewing machine, from what is manually pulled Arduously.

The idler wheel 70 is silica gel wheel, and outer surface forms rough surface.When it is implemented, can be also equipped with outside the idler wheel 70 multiple Outwardly projecting anti-skidding salient point prevents from skidding to enhance frictional force when idler wheel 70 is outer and cloth contacts.

In the present embodiment, which is connect by a speed-ratio regulation component 80 with 20 bias of main shaft.Please refer to figure 3, the speed-ratio regulation component 80 include positioned at outside dial 81, be stacked at 81 inside of the dial and on main shaft 20 Control panel 82 and positioned at the bolt 83 control panel 82 inside and be inserted on holder 10.The dial 81 is circular discs, wherein The heart is equipped with a circular perforation 810.The outer surface of the dial 81 be equipped with scale, please refer to Fig. 4, the dial 81 it is interior It is in the eccentric groove 811 of centrifugal direction extension that surface, which forms one along the periphery of perforation 810,.Please refer to Fig. 5, which is With 81 an equal amount of disk of dial, a bar-shaped trough 820 is which is provided with, a cunning is slideably contained in the bar-shaped trough 820 The surface of block 821, the sliding block 821 has protruded outward a convex block 822.After the dial 81 is covered in control panel 82, convex block 822 It is contained in eccentric groove 811 and can be slided along eccentric groove 811, and pass through top and the scale of connecting rod 40 by 85 priority of a screw The perforation 810 of disk 81 and so that its end is screwed togather the middle part for the sliding block for being fixed on control panel 82, the head of screw 85 is resisted against perforation On the connecting rod 40 in 810 outsides.Multiple hole bodies 823 worn for bolt 83 are additionally provided in the control panel 82.The pin rod of the bolt 83 Be arranged on holder 10 and make its end correspond to control panel 82 hole body setting, the bolt 83 on the pin rod of its plunger side also It is arranged with spring 86, the both ends of the spring 86 can be fixed with plunger and 10 phase of holder respectively.

When using the speed-ratio regulation component 80, the screw in 81 outside of first rotary dial makes it suitably loosen, can be by inserting Pin 83 is arranged in the hole body 823 of control panel 82 and positions control panel 82, is rotated further by centrifugation of the dial 81 by its inner surface Slot 811 drives convex block 822 and is moved along bar-shaped trough 820 with movable slider 821, to keep the screw being arranged on sliding block 821 separate Or close to the center of main shaft 20, and then reach center of the top of connecting rod 40 far from or close to main shaft 20, that is, realizes connecting rod 40 The eccentric distance on top and main shaft 20, the rotating speed for thus controlling idler wheel improve its versatility to be adapted to different machines.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
