Abstract
The utility model discloses a cloth feeding and towing mechanism applied on a seaming device, which comprises a belt (1), a driving wheel (2), a driven wheel (3) and a power supply unit, wherein the belt (1) is sleeved on the driving wheel (2) and the driven wheel (3), the driving wheel (2) is driven to rotate through the power supply unit to enable the belt (1) to move, the cloth feeding and towing mechanism applied on the seaming device is characterized in that the driven wheel (3) is directly arranged on a pressure starting foot (4) of the seaming device, and a part of the belt (1) close to the pressure starting foot (4) is lifted and falls through lifting or pressing the pressure starting foot (4). The cloth feeding and towing mechanism applied on the seaming device has convenient operation, higher efficiency, accurate transmission and small volume.
Description
(1) technical field:
The utility model relates to the work feed tractor of using on a kind of sewing device.
(2) background technology:
The sewing device of transmission plays presser feet on head of sewing machine, play presser feet and pressing the cloth that is tiled on the work top, utilize have gentle hands granny rag material to promote work feed, certain problem appears in this mode aborning, during staff granny rag work feed, because the pulling force size is difficult to control, the speed of work feed is difficult to control, the line density inequality of sewing, and the line of often sewing out is straight inadequately, even the cloth fold gets up the generation waste product.
Some automatic cloth feeding mechanisms have appearred recently, it comprises mechanisms such as motor, train of reduction gears, driving wheel, driven pulley and belt, utilize belt to be pressed on the cloth cover, promotion cloth advances and carries out work feed, and this technical scheme solves the problem of above-mentioned existence substantially, but still heat comes with some shortcomings: 1) height of belt can not be regulated, when cloth being embedded between belt and the work top, operation is trouble very, and inefficiency causes damage to automatic cloth feeding mechanism easily; 2) with common motor and train of reduction gears as power supply unit, volume is big, Heavy Weight, it is low to transmit precision, is difficult to carry out accurate control automatically, influences the quality of cost.
(3) utility model content:
In order to overcome the deficiencies in the prior art, the utility model provides the work feed tractor of using on a kind of easy to operate, efficient is higher, transmission is accurate, volume is little sewing device.
The utility model is achieved through the following technical solutions:
The work feed tractor of using on a kind of sewing device, comprise belt, driving wheel, driven pulley and power supply unit, belt sleeve is contained on driving wheel and the driven pulley, thereby drive the driving wheel rotation by power supply unit and make belt movement, described driven pulley is set directly at rising on the presser feet of sewing device, by carrying or press down on the presser feet, near the belt rising or the decline of a part that plays presser feet.
Above-mentioned described power supply unit is a stepper motor.
Above-mentioned described belt is toothed belt, and described driving wheel and driven pulley are gears.
Above-mentioned described driven pulley has been rotatably connected on the rear portion of presser feet by bearing pin.
Above-mentioned described inboard at belt is provided with the tensioning governor motion, and the tensioning governor motion comprises regulating wheel, support arm, and regulating wheel is rotatably connected on the axle at support arm top.
The utility model compared with prior art, following advantage is arranged: 1) driven pulley is set directly at rising on the presser feet of sewing device, by carrying or press down on the presser feet, belt near a part that plays presser feet rises or descends, convenient distance of regulating between belt and the work top, when being embedded into cloth between presser feet and the work top, simple to operation, operating efficiency is done, and can not cause damage to cloth feeding mechanism; 2) adopt stepper motor, change belt into toothed belt, driving wheel and driven pulley are changed to gear, transmit the precision height, volume is little, and is in light weight, carries out accurate control automatically easily, guarantees the quality of cost, safeguards simple and convenient.
(4) description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is an assembly drawing of the present utility model;
Fig. 3 is that the utility model uses the schematic diagram when sewing device;
Principle cut-away view when Fig. 4 is the utility model use.
(5) specific embodiment:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the work feed tractor of using on a kind of sewing device of the present utility model, comprise belt 1, driving wheel 2, driven pulley 3 and power supply unit, belt 1 is sleeved on driving wheel 2 and the driven pulley 3, thereby drive driving wheel 2 rotations by power supply unit and make belt 1 motion, described driven pulley 3 is set directly at rising on the presser feet 4 of sewing device, and by carrying or press down on the presser feet 4, the close belt 1 that plays the part of presser feet 4 rises or descends.Power supply unit is a stepper motor 5.Belt 1 is toothed belt, and described driving wheel 2 and driven pulley 3 are gears, and driven pulley 3 has been rotatably connected on the rear portion of presser feet 4 by bearing pin 9.In the inboard of belt 1 the tensioning governor motion is set.The tensioning governor motion comprises regulating wheel 6, support arm 7, and regulating wheel 6 is rotatably connected on the axle 8 at support arm 7 tops.
Operation principle of the present utility model is: utilize mentioning and following compression functions of 11 original presser feets of head on the sewing device, before the work, mentioned presser feet 4, because driven pulley 3 is set directly at rising on the presser feet 4 of sewing device, therefore the belt 1 near a part that plays presser feet 4 rises, thereby make near distance increase between the belt 1 of a part that plays presser feet 4 and the work top 10, at this time, can convenient and swiftly put into cloth 12; Then, presser feet 4 is pressed down, belt 1 near a part that plays presser feet 4 descends, thereby make near between the belt 1 of a part that plays presser feet 4 and the work top 10 apart from dwindling, at this time, cloth 12 is clamped by belt 1 and work top 10, when stepper motor 5 work, stepper motor 5 revolutions move a step pitch, just drive driving wheel 2 and angle of driven pulley 3 rotations, belt 1 promotes cloth 12 walking certain distances, realizes automatically accurate work feed, guarantee lines the author of sewing, make cloth be difficult for fold.
The foregoing description is a better embodiment of the present utility model; but embodiment of the present utility model is not limited thereto; other are any not to deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitute, combination, simplify; be the substitute mode of equivalence, be included within the protection domain of the present utility model.
