The specific embodiment

Refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 A, Fig. 5 B and Fig. 5 C, be respectively the three-dimensional appearance schematic diagram of three-dimensional appearance schematic diagram of the present utility model, the utility model part, the decomposing schematic representation of the schematic diagram of another angle of Fig. 2, the utility model part and operating state schematic diagram of the present utility model.As shown in the figure: the sanction line apparatus of a kind of Sewing machines of the present utility model, it is consisted of a Sewing machines 1, a cutting mechanism 2 and a controlling organization 3.

Above-mentioned Sewing machines 1 include the gear unit 12 of a board 11, and board 11 combinations and one in conjunction with board 11 the sewing unit 13 with gear unit 12.

This cutting mechanism 2 is located on board 11 and with sewing unit 13 and is connected, and this cutting mechanism 2 includes a pedestal 21 being incorporated on board 11, the swinging axle 22 on pedestal 21 is located in an activity, one be located in board 11 and with the swing component 23 of swinging axle 22 combinations, one with sewing unit 13 in conjunction with and be resisted against the pusher arm 24 on swing component 23, an activity is located on pedestal 21 and is resisted against the cutting knife 25 on swinging axle 22, and one corresponding with cutting knife 25 and be incorporated into the immovable support 26 on pedestal 21, wherein the bottom of this pedestal 21 is provided with a chip discharging tube 211, one end of this swinging axle 22 has the pushing part 221 that is resisted against cutting knife 25 1 sides, one end of this cutting knife 25 has one and cuts portion 251, these immovable support 26 one end have the blade portion corresponding with cutting portion 251 261, and a side of this cutting knife 25 is provided with flexible member 27, one end of this flexible member 27 and pedestal 21 combinations, the other end is resisted against the opposite side of cutting knife 25.

This controlling organization 3 is connected with cutting mechanism 2, and this controlling organization 3 includes one and is located at the support 31 of pedestal 21 combinations, one that pneumatic cylinder on support 31 32, one are connected with pneumatic cylinder 32 and the movable bayonet lock 33 of being located at cutting knife 25 1 sides and one are connected with pneumatic cylinder 32 and the sensing control element 34 of corresponding sewing unit 13.In this way, by said structure, be combined into the sanction line apparatus of a brand-new Sewing machines.

When the utility model is when using, can be placed in sewing unit 13 and make making thing (not shown), and when sewing unit 13 is when making, its bearded needle axle 131 will produce continuous reciprocating motion, and then drive pusher arm 24, so that pusher arm 24 continues to promote swing component 23, and the pushing part 221 that makes this swing component 23 use swinging axle 22 drives cutting knife 25 to carry out activity, so, in the process of making, as the sensing control element 34 of controlling organization 3 detects while having cloth on the needle plate 132 of sewing unit 13, this sensing control element 34 makes pneumatic cylinder 32 present upper push mode control, and make bayonet lock 33 prop up cutting knife 25, this cutting knife 25 is not driven by pushing part 221, otherwise while detecting on the needle plate 132 of sewing unit 13 without cloth as sensing control element 34, this sensing control element 34 can be controlled pneumatic cylinder 32 is declined, and bayonet lock 33 and cutting knife 25 are departed from, the related cutting knife 25 that makes is because of the band dynamicthrust of swing component 23 with swinging axle 22 set pushing parts 221, one end, restoring force effect with flexible member 27, and freely swing on pedestal 21, so, the portion that cuts 251 of cutting knife 25 can be fixed action that 261 pairs of sutures of blade portion of knife rest 26 carry out automatic cutting (referring to Fig. 5 A, shown in Fig. 5 B and Fig. 5 C), and when cutting, can utilize the chip discharging tube 211 of pedestal 21 bottoms to connect a conduit (not shown), and the suture chip producing during by cutting is derived.

In sum, the sanction line apparatus of Sewing machines of the present utility model effectively improves existing disappearance really, can will make thing in Sewing machines finishes after sewing, by controlling organization, discharge cutting mechanism, make Sewing machines drive cutting mechanism to carry out the automatic cutting of suture, and then reach tailor and fast and accurately spend precisely, and significantly promote the effect of sewing efficiency, obviously make the utility model more progressive, practical and meet operator's demand, reason has possessed the basic important document of patent application, and whence proposes patent application in accordance with the law.

Be the above, it is only preferred embodiment of the present utility model, when not being able to this, limit the technical scope that the utility model is implemented, the simple equivalence of doing with reference to the utility model claims and description therefore all changes and revises, all should still belong to the utility model and obtain in the scope that patent contains in the future, hereby Chen Ming in the lump.
