Utility model content
The purpose of this utility model is to provide a kind of Sewing machines two cloth-dragging wheel device, two groups of mop gears are provided with at the rear of presser feet, mop geared sleeve is connected in single direction ratchet, single direction ratchet is connected with the main shaft in sewing machine head by linkage, and realize working asynchronously with presser feet and stitch, have the advantages that working stability mop is effective, the utility model can by the position of adjustment two groups of linkages in addition, two groups of each rotational steps of mop gear can be realized, thus realize the function of camber line sewing.
For achieving the above object by the following technical solutions:
The two cloth-dragging wheel device of a kind of Sewing machines, comprise sewing machine head and presser feet, it is characterized in that: the described sewing machine head back side is provided with cloth-dragging wheel device, described cloth-dragging wheel device comprises casing, cloth-dragging wheel depression bar, unidirectional cloth-dragging wheel and linkage, the back being connected in sewing machine head of described casing, the cloth-dragging wheel depression bar having two to be arranged in parallel is from top to bottom through casing, cloth-dragging wheel support is provided with in the lower end of every root cloth-dragging wheel depression bar, each cloth-dragging wheel support is provided with unidirectional cloth-dragging wheel, cloth-dragging wheel depression bar is socketed with spring, spring retention applies downward pressure to cloth-dragging wheel depression bar in casing, described unidirectional cloth-dragging wheel comprises mop gear and single direction ratchet, mop geared sleeve is connected in single direction ratchet, single direction ratchet is articulated in cloth-dragging wheel support, and single direction ratchet is also connected by the main shaft of linkage with sewing machine head inside, and two groups of unidirectional cloth-dragging wheels are positioned at the rear of presser feet.
Described linkage comprises swing arm, input connecting rod, tooth axle box, export connecting rod, longitudinal rod and drive rod, the back of sewing machine head is connected at described tooth axle box, the output shaft of tooth axle box is fixed with two and exports connecting rod, export connecting rod and be provided with adjustment hole, the upper end of two longitudinal rods is hinged on the corresponding adjustment hole place exporting connecting rod respectively, lower end and the drive rod of longitudinal rod are hinged, and the drive rod other end drives single direction ratchet to rotate; The back side of described sewing machine head is also provided with a breach, and swing arm is connected through the main shaft of this breach and sewing machine head inside, and free end and the input rod hinge connection of swing arm outside, the power shaft of input connecting rod and tooth axle box is connected.
The utility model is provided with two groups of cloth-dragging wheel devices at presser feet rear, cloth-dragging wheel device can change the angle that cloth-dragging wheel device rotates at every turn by regulating longitudinal rod upper end exporting the position at lever regulated hole place, the pin joint of longitudinal rod upper end regulates each anglec of rotation of cloth-dragging wheel device larger more outward, otherwise it is then less, two longitudinal rod positions are made by regulating, make the difference of two each rotational angles of cloth-dragging wheel device mop gear, thus cause two cloth-dragging wheel device mop strokes different, thus realize camber line sewing, the utility model coordinates the original tooth of Sewing machines and presser feet to have better mop effect, good stability during work, stitch is more even, there is straight line and camber line sewing function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side portion structure schematic diagram of the present utility model.
Detailed description of the invention
As Fig. 1, shown in 2, the two cloth-dragging wheel device of a kind of Sewing machines, comprise sewing machine head 1 and presser feet 2, described sewing machine head 1 back side is provided with cloth-dragging wheel device, described cloth-dragging wheel device comprises casing 3, cloth-dragging wheel depression bar 4, unidirectional cloth-dragging wheel 5 and linkage, the back being connected in sewing machine head 1 of described casing 3, the cloth-dragging wheel depression bar 4 having two to be arranged in parallel is from top to bottom through casing 3, cloth-dragging wheel support 41 is provided with in the lower end of every root cloth-dragging wheel depression bar 4, each cloth-dragging wheel support 41 is provided with unidirectional cloth-dragging wheel 5, cloth-dragging wheel depression bar 4 is socketed with spring 42, spring 42 is placed in casing 3 and applies downward pressure to cloth-dragging wheel depression bar 4, described unidirectional cloth-dragging wheel 5 comprises mop gear 51 and single direction ratchet 52, mop gear 51 is socketed in single direction ratchet 52, single direction ratchet 52 is articulated in cloth-dragging wheel support 41, single direction ratchet 52 is also connected by the main shaft of linkage with sewing machine head 1 inside, and two groups of unidirectional cloth-dragging wheels 5 are positioned at the rear of presser feet 2.
Described linkage comprises swing arm 61, input connecting rod 62, tooth axle box 63, export connecting rod 64, longitudinal rod 65 and drive rod 66, the back of sewing machine head 1 is connected at described tooth axle box 63, the output shaft of tooth axle box 63 is fixed with two and exports connecting rod 64, export connecting rod 64 and be provided with adjustment hole 67, the upper end of two longitudinal rods 65 is hinged on corresponding adjustment hole 67 place exporting connecting rod respectively, lower end and the drive rod 66 of longitudinal rod 65 are hinged, and drive rod 66 other end drives single direction ratchet 52 to rotate; The back side of described sewing machine head 1 is also provided with a breach 11, and swing arm 61 is connected with the main shaft of sewing machine head 1 inside through this breach 11, and the free end of swing arm 61 outside is hinged with input connecting rod 62, and input connecting rod 62 is connected with the power shaft of tooth axle box 63.
