The specific embodiment
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the schematic diagrames of each main building block of the present utility model and corresponding annexation,
In these accompanying drawings, Fig. 1 is a scantling plan of the present utility model, Fig. 2 is the B portion enlarged drawing among Fig. 1, Fig. 3 is the C portion enlarged drawing among Fig. 1, Fig. 4 is that A-A among Fig. 1 is to the view enlarged drawing, syndeton shown in these figure has also shown embodiment of the present utility model, is described further with the assembly relation of industrial sewing machine and the motion and the drive connection of each parts in implementing with regard to the utility model below.
When being installed on the industrial sewing machine, the utility model ° is installed in industrial sewing machine front one side around longitudinal axis Rotate 180 by structure shown in Figure 1, last tugboat (41) and following tugboat (40) are contained in the dead ahead of industrial sewing machine feed dog, and cloth is dragged through entering behind the feed dog to be clipped forward between tugboat up and down.
The motion of each parts of the utility model and drive connection are such:
Buncher (3) obtains power by V-shaped belt pulley (2) from motor, its output synchronous pulley (4) passes through band (58) transferring power synchronously with clutch synchronous pulley (10), pass through steel ball seat (65) again and give last power transmission shaft (20), make power transmission shaft (20) rotation transmission of power.Be fixed on synchronous pulley (21) on the power transmission shaft (20) and synchronous pulley (53) and this is rotatablely moved be divided into two-way, be sent to feeding part and following feeding part through synchronous pulley (53) and (21) respectively.The transmission process of last feeding part is such: synchronous pulley (49) will be passed to the sprocket wheel (52) that therewith is fixed on the tugboat seat axle (62) from the power of uploading moving axis (20) by being with (50) synchronously, sprocket wheel (52) is passed to sprocket wheel (42) by tightener sprocket (46) with power, sprocket wheel (42) is fixed on same axle with last tugboat (41) and promptly goes up on the tugboat axle (61), has therefore realized the rotation of last tugboat (41); Following feeding part transport process is such: synchronous pulley (12) will be passed to the gear (13) that tightens together with it from the power of uploading moving axis (20) by being with (59) synchronously, be fastened on jointly on the lower drive shaft (60) with gear (13) meshed gears (19) and following tugboat (40), therefore realized the rotation of time tugboat (40).The transmission of comprehensive two-way makes tugboat (41) form synchronously with following tugboat (40) and rotates.
Last tugboat (41) to lift motion be such: the back shaft (37) that acts on by cylinder (55) go up to produce lifting force, impel last tugboat left socle (43) and right support (36) to rotate around tugboat seat axle (62), lift thereby will go up tugboat (41), realize disengaging with following tugboat (40); When removing, cylinder (55) does the time spent, last tugboat (41) falls and contacts with following tugboat (40) and keep certain contact force, this contact force is provided by spring (32) and can regulate size by look nut (24), according to the drawing force forward between the upper and lower tugboat how much adjusted of the thickness of the cloth of being sewed and the number of plies, to guarantee that cloth can steadily drag forward.
