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, connects It is arranged in the driven wheel 30 of 20 one end of main shaft, set on 20 other end of main shaft and the company that makes its top be fixedly connected with main shaft 20 Connector sleeve 50, the unilateral bearing 60 on the connector sleeve 50 and the support that the bottom end of bar 40 and the connecting rod 40 is rotatably connected The top of idler wheel 70 on the unilateral bearing 60, the connecting rod 40 is connect with 20 bias of main shaft.In on main shaft 20 on the holder 10 Side is also rotationally equipped with a crossbeam 90 by an axis body, and 90 top of the crossbeam is equipped with an operating lever 91, the operating lever 91 can It is rotatably arranged on holder 10, the operating lever 91
Bottom end be equipped with a cam 92, the end which corresponds to the top of idler wheel 70 is equipped with a pull lever 93, the pulling The bottom end of bar 93 is fixed with connector sleeve 50.
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 sewing machine cloth-dragging wheel apparatus to processing the tractive force of cloth application backward on sewing machine, from manually What is pulled is laborious.The idler wheel 70 can realize that its lift is put by operating operating lever 91, specifically can by moving the operating lever 91, So that cam 92 below is resisted against on crossbeam 90, so that crossbeam 90 is connected and lifted on the end of pull lever 93, pull lever 93 is made to pull Connector sleeve 50 is lifted up together with idler wheel 70, to realize the upper lift of idler wheel 70, to facilitate the placement of lower section cloth;It is on the contrary then Realize putting down for idler wheel 70.
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.
When it is implemented, the lower section of the idler wheel 70 can also be equipped with another wheel, which is metal wheel, cloth clamp when use Between the idler wheel 70 and another wheel.When practical application, the side of another wheel and idler wheel 70 can also be connected with a tooth Mechanism is taken turns, to drive another wheel to rotate when idler wheel 70 rotates.
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.
