Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of Sewing machines, particularly a kind of link gear of sewing machine dragging wheel.
Background technology
Along with the development of science and technology and textile industry, the technology of Sewing machines is also more and more ripe, and kind is also more various, not only comprises domestic sewing machine, also comprise and be applied to industrial industrial sewing machines, such as flat seam machine, chain seam machine, overlock machine and flat seaming machine etc.The rear tugboat of the existing flat seam machine with trailing wheel has outer joining and two kinds of forms of one, is nearly all that presser feet and rear tugboat separately lift at present for tugboat after integral type flatcar, and two link gears need to be set simultaneously could normally work, and structure is more complicated.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of link gear of sewing machine dragging wheel, and it is simple in structure, easy and simple to handle, can realize the automatic lifting of rear tugboat.
The purpose of this utility model can realize by following technical proposal: a kind of link gear of sewing machine dragging wheel, described Sewing machines comprises knee lifting rod, rear tugboat and presser feet, it is characterized in that, on described rear tugboat, there is the vertical pivot of vertical setting, described link gear comprises that rear tugboat promotes connecting rod, rear tugboat lift lever, be used for the front lever of presser foot lifter and the rear tugboat lift block that is arranged on vertical pivot with the interlock of knee lifting rod, before described rear tugboat lift lever one end and presser foot lifter, lever is hinged, the upper end that the other end and rear tugboat promote connecting rod is hinged, the lower end that described rear tugboat promotes connecting rod is connected on rear tugboat lift block, before described presser foot lifter, on lever, be connected with the presser foot lifter riser of energy oscilaltion.
In the technical program, before presser foot lifter, lever is hinged on Sewing machines, it can rotate under the knee lifting rod of Sewing machines drives, drive presser feet lifting by presser foot lifter riser, can also link by driving rear tugboat lift lever and rear tugboat to promote connecting rod, rear tugboat is promoted, and this is simple in structure, but also can realize the automatic lifting of presser feet and rear tugboat.
In the link gear of above-mentioned sewing machine dragging wheel, described rear tugboat promotes the strip guide groove on connecting rod with vertical setting, is provided with the hinge screws that can slide on above-mentioned strip guide groove on described rear tugboat lift block.In the time using after rear dragging wheel spanner independent lift tugboat, rear tugboat lift block drives hinge screws to slide in rear tugboat promotes the strip guide groove of connecting rod, can not promote connecting rod to rear tugboat and cause interlock.
In the link gear of above-mentioned sewing machine dragging wheel, before described presser foot lifter lever comprise cylindric location axial region, for carrying lever portion that presser foot lifter pull bar is connected and lifting bar portion for being connected with presser feet with knee, described lever portion and lifting bar portion are shaft-like and crossing being positioned on perpendicular, described location axial region horizontally set and be vertically connected on lever portion and the cross-shaped portion of lifting bar portion on, described rear tugboat lifting lever be connected to location axial region on.In the technical program, can carry presser foot lifter pull bar by knee and act in lever portion, make the axial rotation of the front lever of presser foot lifter around location axial region, and make rear tugboat carry out lifting; Also can be by presser foot lifter cam wheel in lifting bar portion, make the axial rotation of the front lever of presser foot lifter around location axial region, and make rear tugboat carry out lifting.
In the link gear of above-mentioned sewing machine dragging wheel, on described pressure foot lifting plate, there is the gathering sill of vertical setting.This gathering sill can carry out pressure foot lifting plate spacing, guarantees that pressure foot lifting plate can only move up and down.
In the link gear of above-mentioned sewing machine dragging wheel, on described pressure foot lifting plate, have one for hanging the stress surface of presser feet, described stress surface arranges upward.Presser feet hangs on stress surface, in the time that pressure foot lifting plate upwards promotes, can drive presser feet to rising, and presser feet and pressure foot lifting plate is non-fixing mechanism, when presser feet is to rising, can't drive pressure foot lifting plate to move upward.
In the link gear of above-mentioned sewing machine dragging wheel, the sidewall of described location axial region has an output locating surface, and described output locating surface is made as plane, and described rear tugboat lifting lever is sleeved on output locating surface.When lever stress before presser foot lifter can drive output locating surface with equal angular rotation in the time locating the axial rotation of axial region, thus tugboat lifting after driving.
In the link gear of above-mentioned sewing machine dragging wheel, the below of described pressure foot lifting plate is provided with presser feet spanner and a lobe plate.In the time pulling presser feet spanner, lobe plate rotates and can drive pressure foot lifting plate and lifting bar portion to carry out lifting, thereby before making presser foot lifter, lever energy is around the axial rotation of locating axial region.
In the link gear of above-mentioned sewing machine dragging wheel, on described vertical pivot, be arranged with a spring, the bottom of vertical pivot is connected on rear tugboat, and top, top is provided with pressure regulating screw, upper end and the pressure regulating screw of described spring lean, and lower surface and rear tugboat lift block lean.Pressure regulating screw and spring can be adjusted the compress power size of rear tugboat, and spring can also be used for rear tugboat to reset.
In the link gear of above-mentioned sewing machine dragging wheel, on described rear tugboat, be provided with the rear dragging wheel spanner for tugboat after independent lift.Rear dragging wheel spanner is hinged on Sewing machines, can promote rear tugboat separately by rotating rear dragging wheel spanner.
Compared with prior art, the utility model is simple in structure, can be by tugboat after rear dragging wheel spanner independent lift, again by the lifting structure of presser feet and rear tugboat is united two into one, thereby the interlock knee of having realized presser feet and rear tugboat is put forward effect, practical, and it only needs the structure of lever before presser foot lifter to change, and do not need original Sewing machines internal structure to transform on a large scale, and transformation difficulty is low, and improvement cost is low.
