Abstract
The utility model relates to a sewing machine with sewing overedge device, which comprises a common double-line lockstitch sewing machine and a triple-line chain overseaming stitch mechanism. All the functions and the performances of the original sewing machine remaining unchanged, the overedgeing mechanism is arranged in the limited space of the original sewing machine to realize the multi-uses of a sewing machine with the function of cup seaming. The utility model has the advantages of reasonable design, compact structure, convenience for carrying, convenient operation and stable performance, which is suitable for the work of common sewing, overedge sewing, embroidery, etc., of woollen cloth, velour, silk, satin, terylene, cotton, hemp, chemical and blended fabric, etc.
Description
The utility model is relevant with multifunction household sewing machine.
Existing family expenses ordinary sewing machine mostly only has the function of flush joint.Because chemical ﹠ blended fabric has replaced cotton goods gradually, making a large amount of clothes all needs lock seaming.But buy Sewing machines and cap seaming machine in the family simultaneously, the one, cost is too high uneconomical, and the 2nd, occupation of land side is unrealistic.Go lock seaming as clothes being taken the outside, also very inconvenient.
Task of the present utility model is that with existing ordinary sewing machine be the parent form machine, utilizes its limited space, and reasonable Arrangement on the flush joint performance that keeps the parent form machine and other performance basis of invariable, is set up lock seaming overseam mechanism.Provide a kind of flat bag dual-purpose, simple in structure, easy to use, most of part and the general and cheap Sewing machines of ordinary sewing machine in addition, to be suitable for the needs of family and sewing specialist.
Flat bag two-purpose sewing machine of the present utility model is made up of common two-wire lock-type chain stitch flat seam machine and the three-way chain type over-lock stitch lock seaming two large divisions of mechanism.As shown in drawings, flush joint part power by on take turns (1) and go up axle (3) input by band crank throw (2).Flush joint thread take-up mechanism (4) and last axle interlock; The power of flush joint string-hooking mechanism (5) is passed to balance staff (7) through crank throw (2) and big connecting rod (6), pays (8) by the prong crank gearing again and passes to the input of lower shaft (9) back; The power that flush joint is lifted tooth mechanism (10) by balance staff (7) through the cam drive of feed lifting fork mouth pay (11) pass to feed lifting rock shaft (12) after input; The power of flush joint cloth feeding mechanism (13) pays (14) by the cam drive of last beam warp work feed prong and tooth fork (15) is passed to the input of cloth pushing shaft (16) back.The utility model is the most outstanding to be characterised in that overseam mechanism is arranged in the limited space of flush joint machine tool on the sewing performance and other performance basis of invariable that keeps aforementioned flat seam machine.The action of overseam part is by clutch (17) control.There are an overseam kinematic link (22) one ends to be hinged in big connecting rod (6) the bar portion, the other end joins through universal joint (23) and clutch (17), described clutch (17) turns (24) again and joins with hyperbolic, turn (24) through hyperbolic power is flowed to overseam thread take-up mechanism (18) and overseam string-hooking mechanism (19) respectively.The power of overseam cloth feeding mechanism (20) is directly imported from cloth pushing shaft (16); Overseam is lifted the power of tooth mechanism (21) and is directly imported by feed lifting rock shaft (12).The overseam thread take-up mechanism (18) of flat bag two-purpose sewing machine of the present utility model can be formed by having eedle slide block (25), slide block connecting rod (26), the punch block lever (28) of adorning punch block.Punch block lever (28) turns (24) by take-up kinematic link (29) and hyperbolic and joins.Described overseam string-hooking mechanism (19) can be formed by connecting with punch block connecting rod (32) by large bending needle frame (30) and little looper frame (31).Large bending needle frame (30) is affixed with punch block crank (33), and punch block crank (33) turns (24) by bearded needle kinematic link (34) and hyperbolic and joins.Described clutch (17) can be by the clutch shaft (37), the clutch fixed body (38) that has pin-and-hole that are installed in clutch-pedal support (36) on Sewing machines base plate (35) back side, join with universal joint, have annular groove on it and the clutch wrench (41) of clutch body (39), clutch pin (40) and the band biconvex ear that can slide on clutch shaft etc. is formed.Lug of clutch wrench is hinged on the support, is equipped with on another lug to stir the control screw (42) that clutch body slides along clutch shaft.Hyperbolic turns (24) and just is loaded between support (36) and the clutch fixed body (38), and sky is enclosed within on the clutch shaft (37).Clutch fixed body (38) fixes on the clutch shaft (37) with pin lock, and hyperbolic turns and also has clutch pin-and-hole (43) on (24).Described overseam is lifted tooth mechanism (21) and is made up of the retainer (27) that is installed in the feed lifting rock shaft crank (44) on the feed lifting rock shaft (12) and is connected with feed dog (45) on it.Have prong and feed lifting rock shaft crank (44) on the retainer and fit in kinematic pair.Described overseam cloth feeding mechanism (20) is made up of the crank of tooth frame (46) and the retainer (27) that are fixed on the cloth pushing shaft (16).Crank of tooth frame (46) and retainer (27) are connected through the hinge.On the base plate of flat bag two-purpose sewing machine of the present utility model (35), the T shape through hole (49) that an installation kit suture needle plate is arranged in through hole (48) inboard that casing (47) is installed leans on cloth pushing shaft (16) Bian Youyi that the installation base (50) of overseam string-hooking mechanism is installed near through hole (48) and T shape through hole (49).Base plate (35) is gone up the processing plane (51) that clutch (17) is installed by cloth pushing shaft (16) Bian Youyi in through hole (48) outside, have the sunk screw hole (52) that 2 installation clutches use in this plane (51) and the slot (53) of clutch wrench (41) usefulness is installed.
Flat bag two-purpose sewing machine of the present utility model has all kept outside the former sewing machine for covering chain stitch all functions, has increased overseam lock seaming part, has realized planting function more than flush joint, the lock seaming, and is economical and practical.And have that reasonable in design, compact conformation is simple, stable performance, be easy to carry, advantage such as easy to use.Be applicable to the operation such as flush joint, lock seaming, embroidery of various Buddhist nuns, suede, silk fabric, satin, terylene, cotton, fiber crops, chemical ﹠ blended fabric etc.
