The utility model content
What the technical problems to be solved in the utility model was to provide a kind of Sewing machines drags the rumble device, and this drags the rumble device can provide constant pressure on cloth, so that the generation fold that cloth is tried one's best few.
For solving the problems of the technologies described above, the utility model adopts following technical proposals.
A kind of Sewing machines drag the rumble device, comprising:
One support, described support are fixed on the described Sewing machines;
One drags dolly, and the described dolly that drags is provided with drive source and drag rumble, the output of described drive source to be connected to the described rumble that drags,
It is characterized in that: described support is provided with a chute, and the described dolly that drags connects a slide bar, and described slide bar is slidably disposed in the described chute.
In technique scheme, the whole dolly that drags is to be fixed on slidably on the support, drags dolly vertically to arrange, and its weight mainly concentrates on dragging on the rumble of end, finally is pressed on the cloth to be dragged.And the rumble rotation is dragged in the drive source drive, realizes dragging cloth.
Dragging in the rumble device of this Sewing machines of the present utility model, be connected with rotationally eccentric wheel disc on the described support, the described dolly that drags is provided with locating shaft, and described locating shaft is positioned at the top of described eccentric wheel disc.Rotate eccentric wheel and can adjust the height of locating shaft, and then manually adjust the height that drags rumble.
Dragging in the rumble device of this Sewing machines of the present utility model, be provided with a breach apart from pivot position farthest on the described eccentric wheel disc.Snap in wherein during described this breach of locating shaft process, and then realize whole location of dragging dolly.
Dragging in the rumble device of this Sewing machines of the present utility model, be provided with the roller for reducing described slide bar frictional force in the described chute.
Dragging in the rumble device of this Sewing machines of the present utility model, described drive source is stepping circuit.The good speed adjustment features of stepper motor, step pitch is controlled, is suitable for using in the utility model.
That implements this Sewing machines of the present utility model drags the rumble device, has following beneficial effect: drag dolly to be slidably disposed on the support, so can carry out height fine adjusting function according to the thickness of cloth.The pressure that drags rumble to be applied on the cloth mainly is stepper motor and the weight of dragging dolly, and this strength is constant.

The part description of reference numerals: support 1, eccentric wheel disc 101, chute 102, breach 103, handle 104, drag dolly 2, drive source 201, drag rumble 202, slide bar 203, locating shaft 204, belt 205, cloth 3, sewing machine hand-wheel 001, encoder 002, control box 003, driving box 004.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
This Sewing machines of the present utility model as shown in Figures 1 to 4 drag the rumble device, comprise support 1 and drag dolly 2.This sewing function is made the goods such as the fabrics such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, and is not limited only to cloth 3.
Described support 1 is fixed on the described Sewing machines.Be connected with rotationally eccentric wheel disc 101 on the described support 1, the described dolly 2 that drags is provided with locating shaft 204, and described locating shaft 204 is positioned at the top of described eccentric wheel disc 101.Be provided with a breach 103 apart from pivot position farthest on the described eccentric wheel disc 101.Eccentric wheel disc 101 is connected to leader 104 coaxially, so that the user manually adjusts.
Describedly drag dolly 2 to be provided with drive source 201 and drag rumble 202, the output of described drive source 201 is connected to the described rumble 202 that drags by belt 205.Described support 1 is provided with a chute 102, and the described dolly 2 that drags connects a slide bar 203, and described slide bar 203 is slidably disposed in the described chute 102.Be provided with the roller for reducing described slide bar 203 frictional force in the described chute 102.
Circuit control schematic diagram as shown in Figure 5.Encoder 002 gathers the rotating signal of sewing machine hand-wheel 001, and signal is sent to control box 003.Control box 003 carries out subdivision, and exports control signal to driving box 004, and this driving box 004 drags rumble 202 by drive source 201 drives.In the present embodiment, the rotation that rumble 202 is dragged in sewing machine hand-wheel 001 control, and the rotation of sewing machine hand-wheel 001 is corresponding with Sewing machines stitching speed and suture direction, thus drag rumble 202 can apply different rotating speeds, to respond different stitching speed constantly.
In sum, in the utility model, owing to drag dolly 2 to be slidably disposed on the support 1, under free state, drag dolly 2 meetings along chute 102 down slidings, until drag rumble 202 to be pressed on the cloth 3.The whole dolly 2 that drags puts on this cloth 3 with its gravity, realizes the compression to cloth, in order to drag rumble 202 to pull cloth 3 when rolling, to guarantee the straight of cloth 3.Drag the height of rumble 202 to regulate according to the thickness of cloth 3, and because to drag the self gravitation of dolly 2 be constant, can not change because of the change of dragging rumble 202 height, obvious goal of the invention of the present utility model is accomplished.
