Description
Technical field:
The utility model relates to sewing-machine equipment technical field, refers in particular to a kind of wide pin hyte of Sewing machines.
Background technology:
Existing Sewing machines need to use multiple needle positions syringe needle according to operation to carry out high efficiency and makes, multiple needle positions syringe needle arranges a plurality of pins position and a plurality of eedles is installed on same syringe needle, syringe needle multimachine pin under the drive of same needle bar is made material simultaneously like this, thereby can improve sewing efficiency.Yet due to the restriction of the factors such as structure, existing Sewing needles bit width is the highest can only reach 50mm, therefore making width will be restricted, and cannot meet the operation of making of wider pin position.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of wide pin hyte of Sewing machines is provided.
The technical scheme that the utility model is realized its object employing is: the wide pin hyte of Sewing machines, described wide pin hyte comprises syringe needle needle plate assembly, feeding material component and rotating shuttle assembly, wherein, described syringe needle needle plate assembly comprises the needle bar of syringe needle and connecting needle, also comprises big or small presser feet and the needle plate that is positioned at big or small presser feet below; Described feeding material component comprises feed spool and is arranged on the feeding crank of its end, this feeding crank is connected with a pair of retainer, the top of two retainers is provided with feeding tooth plate, it is positioned under needle plate, the below of described retainer is provided with horizontal " U " shape feed lifting fork, and in feed lifting fork, upper surface is conflicted with the eccentric wheel being arranged on lower shaft of sewing machine; Described rotating shuttle assembly comprises and is a pair ofly arranged in opposite directions board lower surface and lays respectively at needle plate and the shuttle frame of feeding tooth plate both sides, on described shuttle frame, longitudinal rotating shuttle is installed, longitudinally the rotating shaft bottom of rotating shuttle is provided with longitudinal pinion, and described longitudinal pinion is meshed by the gear wheel being arranged on lower shaft of sewing machine.
The pin bit width of described syringe needle needle plate assembly is 50mm～140mm.
The mode that the utility model adopts rotating shuttle assembly and feeding material component alternative expression to install, make to have between two shuttle framves enough large distances, and then can realize wider pin bit width, operation is made in the wide pin position that the applicable pin bit width of energy reaches 140mm, meet the processing request of making of specialities, enhance productivity.
Accompanying drawing explanation:
Fig. 1 is decomposition texture schematic diagram of the present utility model.
The specific embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As shown in Figure 1, the wide pin hyte of Sewing machines described in the utility model, described wide pin hyte comprises syringe needle needle plate assembly 1, feeding material component 2 and rotating shuttle assembly 3, wherein, described syringe needle needle plate assembly 1 comprises the needle bar 12 of syringe needle 11 and connecting needle 11, also comprises big or small presser feet 13 and the needle plate 14 that is positioned at big or small presser feet 13 belows;
Described feeding material component 2 comprises feed spool 21 and the feeding crank 22 that is arranged on its end, and the top that this feeding crank 22 is connected with a pair of retainer 23, two retainers 23 is provided with feeding tooth plate 24, and it is positioned under needle plate 14; The below of described retainer 23 is provided with horizontal " U " shape feed lifting fork 25, and the interior upper surface of feed lifting fork 25 is conflicted with the eccentric wheel 26 being arranged on lower shaft of sewing machine 4;
During feeding, because driving the eccentric wheel 26 on it, lower shaft of sewing machine 4 rotations rotate, eccentric wheel 26 drives feed lifting fork 25 to move upward, and then drive retainer 23 and feeding tooth plate 24 to move upward, make feeding tooth plate 24 coordinate and push down cloth with big or small presser feet 13, then, under the drive of feed spool 21, feeding crank 22 swings forward, and then by two retainers 23 and the 24 along continuous straight runs push-and-pulls of feeding tooth plate, cloth is advanced; After feeding, because the effect feed lifting fork 25 of eccentric wheel 26 and gravity and retainer 23, feeding tooth plate 24 move downward, unclamp cloth, homing, the feeding crank 22 of horizontal direction operation simultaneously also resets under the drive of feed spool 21, runs so forth and realizes feeding.
Described rotating shuttle assembly 3 comprises and is a pair ofly arranged in opposite directions board lower surface and lays respectively at needle plate 14 and the shuttle frame 31 of feeding tooth plate 24 both sides, longitudinal rotating shuttle 32 is installed on described shuttle frame 31, longitudinally the rotating shaft bottom of rotating shuttle 32 is provided with longitudinal pinion 33, and described longitudinal pinion 33 is by gear wheel 34 engagements that are arranged on lower shaft of sewing machine 4.Be on shuttle frame 31, to there is the through hole passing for lower shaft of sewing machine 4 and hold gear wheel 34 and the space of longitudinal pinion 33 rotations; The lower shaft of sewing machine 4 of horizontal direction rotarily drives gear wheel 34 rotations, between gear wheel 34 and longitudinal pinion 33, is helical teeth engagement, and then drives longitudinal pinion 33 and longitudinal rotating shuttle 32 to rotate around longitudinal axis, carries out unwrapping wire.
The pin bit width of described syringe needle needle plate assembly 1 is 50mm～140mm.
The mode that the utility model adopts rotating shuttle assembly and feeding material component alternative expression to install, make to have between two shuttle framves enough large distances, and then can realize wider pin bit width, operation is made in the wide pin position that the applicable pin bit width of energy reaches 140mm, meet the processing request of making of specialities, enhance productivity.
