Abstract
The utility model discloses a cloth collection device of a sewing machine. The cloth collection device of the sewing machine comprises a roller fixedly connected with a roller shaft which is connected with a machine frame and can rotate relative to the machine frame, one side of the roller shaft is connected with a transmission wheel, a cylindrical pin is arranged on the surface the outer side of the transmission wheel and is hinged on a connecting rod, the other end of the connecting rod is hinged with a rocker which is hinged on the machine frame, and the length of the rocker is larger than the distance between the cylindrical pin and the center of the transmission wheel. The rocker, the connecting rod, the machine frame and the cylindrical pin form a plane mechanism. When the length of the rocker is larger than the distance between the cylindrical pin and the center of the transmission wheel, swinging of the rocker can drive the transmission wheel through the cylindrical pin to carry out circling motion. The rocker is swung, the cylindrical pin can be driven to carry out the circling motion, and therefore the roller is driven to rotate to take up workpieces.
Description
Technical field
The utility model relates to a kind of textile apparatus, especially a kind of Sewing machines cloth collector.
Background technology
In the sewing process, the cloth after processing need to move apart syringe needle, and prior art is generally by manually cloth being moved away, and this mode has not only strengthened workman's workload, and is careless slightly, exerts oneself excessively also can pull apart syringe needle.And the cloth that moves away from generally is deposited in a place, easy fold, and dust stratification, unfavorable to the cloth quality, affect its follow-up processing.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of convenience and can receives continuously the Sewing machines cloth collector of cloth.
For addressing the above problem, the utility model provides a kind of Sewing machines cloth collector, comprise the roller affixed with roller shaft, roller shaft is connected on frame and can rotates relative to described frame, and roller shaft one side is connected with drive, and the drive outer surface is provided with straight pin, straight pin is hinged on connecting rod, the other end of connecting rod is hinged with rocking bar, and rocking bar is hinged on frame, and the length of rocking bar arrives drive size radially greater than straight pin.
As further improvement of the utility model, the end that rocking bar is connected with frame is provided with the those widened sections that width increases, and rocking bar is hinged on described frame by described those widened sections.
As further improvement of the utility model, the those widened sections back side is connected with the spring that is connected with frame.
As further improvement of the utility model, the those widened sections front is provided be used to the suspender belt that holds operator foot.
Beneficial effect:
(1) plane mechanism that consists of of rocking bar, connecting rod, frame and straight pin, greater than straight pin during to radially size of drive, the swing of rocking bar will drive drive by straight pin and move in a circle when the length of rocking bar;
(2) the rocking bar lower end is provided with those widened sections, is convenient to pin the rocking bar application of force;
(3) the those widened sections bottom arranges spring, is convenient to it after rocking bar presses down and upsprings;
(4) the those widened sections front is provided be used to the suspender belt that holds operator foot, and operator foot lifts just and can mention rocking bar.
Description of drawings
Fig. 1 is the front view of the utility model Sewing machines cloth collector;
Fig. 2 is the top view of the utility model Sewing machines cloth collector;
Comprising: frame 1, roller shaft 2, drive 3, roller 4, workpiece 5, straight pin 6, connecting rod 7, rocking bar 8, spring 81, those widened sections 82.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1 and Fig. 2, the utility model comprises that is used for the roller 4 that volume is put the workpiece 5 such as cloth, woollen blanket, leather, roller 4 is fixedly connected with roller shaft 2, roller shaft 2 is connected on frame 1, and can rotate relative to frame 1, and roller shaft 2 one sides also are fixedly connected with drive 3, be fixedly installed a straight pin 6 on the end face in drive 3 outsides, straight pin 6 is hinged with connecting rod 7, and connecting rod 7 is hinged on rocking bar 8, and rocking bar 8 is hinged on frame 1.Rocking bar 8, connecting rod 7, frame 1 form four-bar linkage with the plane mechanism that straight pin 6 forms, straight pin 6 is to the distance in the power transmission shaft center of circle during less than the length of rocking bar 8, formation crank rocker 8 mechanisms, when this moment, rocking bar 8 swung in certain angle, straight pin 6 will drive drive 3 and move in a circle, between drive 3 and roller shaft 2, be fixedly connected with between roller shaft 2 and roller 4, so drive 3 moves in a circle, driving roller 4 is moved in a circle, carry out coiled strip.the end that rocking bar 8 is connected with frame 1 is provided with the those widened sections 82 that width increases, those widened sections 82 is used for holding people's step, the back side of those widened sections 82, namely the one side relative with frame 1 upper surface is connected with a side of spring 81, the opposite side of spring 81 is connected on the upper surface of frame 1, because pressure is more prone to respect to pulling force, the convenient realization, when operator foot presses down those widened sections 82, need to overcome the elastic force of spring 81, to store in some in spring 81, when needs are mentioned those widened sections 82, spring 81 power discharge, form with pulling force making a concerted effort of making progress, alleviated the burden of pulling force.Those widened sections 82 fronts are provided be used to the suspender belt that holds operator foot, the those widened sections 82 of convenient operation person foot pull-up rocking bar 8.
The above describes in detail embodiment of the present utility model by reference to the accompanying drawings, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
