Description
Technical field
The utility model relates to a kind of Sewing machines elastic webbing hold down gag, be hubbed at the top of making operating area of Sewing machines, to compress or to decontrol the elastic webbing made between operating area by pressure zone portion and Sewing machines, reach make elastic webbing after cutting band more than band final sewing process in keep set tension force and flexible object.
Background technology
Many clothings all need to make elastic webbing (being commonly called as " elastic cord "), such as: underpants, brassiere etc.Tradition is all according to personal experience by the skilled workman that makes held and tighten elastic webbing on the other hand, and another hand operated sewn object advances along needle plate.But such manual mode of operation can cause every skilled to make workman at the every part sewn object of sewing, the tension force applied elastic webbing is not identical, cause quality heterogeneity, be still more by multidigit skilled make workman make respectively time, the difference of quality is larger.Do not meet excelsior high-quality demand.
In addition, time for a long time with manual tension elastic webbing, not only the skilled employment injuries making workman will be caused, and every is made workman and all cannot operate the long period.
Though in recent years had manufacturer specially to manufacture " elastic webbing tape-feed ", and be attached to original Sewing machines near at one's side, namely close to the position of making workman front, expect to replace manpower with machine, and by the controllability of machine, control the degree of tightness quality of the elastic webbing of each part sewn object equably.
But when elastic webbing makes stroke close at the end, must elastic webbing be cut off.Though aforesaid elastic webbing tape-feed also has automatic scissors automatically can cut off elastic webbing, because this " elastic webbing tape-feed " there is no the pressure zone action before cutting band, causing latter end elastic webbing to relax because cutting the action of band, forming defective products.
In view of this present inventor, gives research and innovation, discloses the elastic webbing of Sewing machines shown in the utility model hold down gag, make elastic webbing after cutting band more than band final sewing process in keep set tension force and elasticity.
Utility model content
Technical problem underlying to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and provides a kind of Sewing machines elastic webbing hold down gag, make elastic webbing after cutting band more than band final sewing process in keep set tension force and elasticity.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Sewing machines elastic webbing hold down gag, comprising: pressure zone component, be hubbed at the top of making operating area of Sewing machines, this pressure zone component has pressure zone portion; And, actuating mechanism, be connected with pressure zone component to driven nature, to drive the pressure zone portion of pressure zone component to touch relative to the operating area pressure of making of Sewing machines or be separated, and then compress or decontrol the elastic webbing made between operating area by pressure zone portion and Sewing machines, reach make elastic webbing after cutting band more than band final sewing process in keep set tension force and flexible object.
The Sewing machines elastic webbing hold down gag that the utility model discloses, wherein actuating mechanism comprises: driving shaft, and what be hubbed at Sewing machines makes on operating area; And actuator, is arranged between Sewing machines and driving shaft, so that activated drive axle turns relative to sewing arbor.
The Sewing machines elastic webbing hold down gag that the utility model discloses, wherein actuator is vapour pressure cylinder assembly.
The beneficial effects of the utility model are, make elastic webbing after cutting band more than band final sewing process in keep set tension force and elasticity.

Detailed description of the invention
Refer to shown in Fig. 1 to Fig. 4, the utility model is intended to provide a kind of Sewing machines elastic webbing hold down gag 10, and comprising: pressure zone component 20, be hubbed at the top of making operating area 40 of Sewing machines 60, this pressure zone component 20 has pressure zone portion 21; And actuating mechanism 30, be connected with pressure zone component 20 to driven nature, to drive the pressure zone portion 21 of pressure zone component 20 press tactile relative to the operating area 40 of making of Sewing machines 60 or be separated, and then the elastic webbing 50 (note: make operating area 40 and be the region of installing cloth conveying teeth and needle plate, not shown cloth conveying teeth and needle plate) made between operating area 40 compressing or decontrol by pressure zone portion 21 and Sewing machines 60.
Refer to shown in Fig. 1 to Fig. 4, the Sewing machines elastic webbing hold down gag 10 that the utility model discloses, wherein actuating mechanism 30 comprises: driving shaft 31, by two bearing blocks 33,33 making operating area 40 be fixed near Sewing machines 60, and be hubbed at Sewing machines 60 make on operating area 40; And actuator 32, wherein one end borrows holder 34 to be hubbed on Sewing machines 60, a connecting rod 35 and driving shaft 31 pivot joint are borrowed in one end in addition, actuator 32 is made to be arranged between Sewing machines 60 and driving shaft 31, so that activated drive axle 31 turns relative to sewing arbor, and then the pressure zone component 20 making to be locked in driving shaft 31 makes operating area 40 pivotable relative to Sewing machines 60.To drive the pressure zone portion 21 of pressure zone component 20 press tactile relative to the operating area 40 of making of Sewing machines 60 or be separated, and then to compress or decontrol the elastic webbing 50 made between operating area 40 by pressure zone portion 21 and Sewing machines 60.
Refer to shown in Fig. 1 to Fig. 4, the Sewing machines elastic webbing hold down gag 10 that the utility model discloses, wherein actuator 32 can be the actuating mechanism of vapour pressure cylinder assembly or other pattern.The utility model will not from limit.
During operation, as shown in Figures 3 and 4, the motor 71 of existing elastic webbing tape-feed 70 drives pinch roller 72 to rotate, under the cooperation of pressure zone idle pulley 73, push down the rear end of elastic webbing 50, cloth pressing foot (not shown) and cloth conveying teeth (non-icon) then push down the front end of elastic webbing 50, and between this front and back end, rotating speed by motor 71 controls the tension force (this is structure and the function of existing " elastic webbing tape-feed ", and it will not go into details for this reason for the utility model) of elastic webbing 50.
Carry out period making stroke, the pressure zone portion 21 of pressure zone component 20 of the present utility model be leave Sewing machines 60 make operating area 40, elastic webbing 50 can be successfully sewn.
Make stroke at the end when elastic webbing 50, elastic webbing 50 is still by pinch roller 72 and pressure zone idle pulley 73, and the tensioned state of tension force is expected in the control of cloth pressing foot and cloth conveying teeth and presenting.Under the operation of making workman, starting switch (not shown) makes actuator 32 extend and through connecting rod 35, driving shaft 31 and drive pressure zone component 20 to rotate counterclockwise and exert pressure to elastic webbing 50, to maintain elastic webbing 50 due tension force originally.Then, scissors 74 action of elastic webbing tape-feed 70, cuts off the rear end of elastic webbing 50.Thus make elastic webbing 50 self-pressure band member 20 press the position of touching to press the elastic webbing of that section between tactile position still can maintain set tension force and elasticity to cloth pressing foot (not shown) institute, still can possess set tension force and elasticity to make follow-up the elastic webbing made on object to be sewn.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
