Abstract
The utility model relates to a hemming machine thread releasing device with adjustable, including tension releasing ware frame, tension releasing board, cylinder tension releasing ware erect two the fixed stabilizer blades of putting and hemming machine organism rigid coupling, cylinder body and tension releasing ware frame rigid coupling, the piston rod of cylinder and the left end rigid coupling of tension releasing board of cylinder, set up first slotted hole on the tension releasing board, the screw passes first slotted hole can control displacement, its characterized in that for tension releasing ware frame with the fixed tension releasing board that makes of tension releasing ware frame: the tension releasing board be divided into left subtotal right part branch, left subtotal right part divides and all has respective poker rod, the right -hand member that the left part divides sets up the second slotted hole, the left end that the right part divides sets up the third slotted hole, two at least fasteners pass the second slotted hole and divide the rigid coupling to be in the same place left subtotal right part with the third slotted hole. Compared with the prior art, the utility model discloses a simple construct has realized that the poker rod width is adjustable to realize the mesh of the adaptable current different hemming machines of thread releasing device.
Description
Technical field
The utility model relates to a kind of adjustable overedger thread-loosening device, belongs to sewing-machine equipment technical field.
Background technology
The disclosed a kind of computer overedger loose ends device of Chinese utility model patent that existing overedger is CN204151546U as publication number, comprise the loose ends device frame 2 with fixed support 8, fixed support 8 is provided with bracket holes 9, described loose ends device frame 2 fronts are provided with the fixing thread tension releasing disc 7 of screw 6, self-return cylinder 5 is installed after it, self-return cylinder 5 one end are provided with the cylinder turnover pull bar 1 moving left and right for promoting thread tension releasing disc 7, its other end is provided with air inlet gas-tpe fitting 3, air inlet gas-tpe fitting 3 is connected with electromagnetism Pneumatic valve gas outlet, for cylinder provides Gas Energy Source, nut 4 for adjustable pressure size is also installed on air inlet gas-tpe fitting 3, by air pressure size, thread tension releasing disc is promoted to degree of tightness control. described thread tension releasing disc 7 is tabular shape, its lower end has two claws 71, claw 71 is positioned at loose ends device fixed support 8 sides, when in cylinder during without gas pressure, the claw of thread tension releasing disc and device side line tension disc are in gapped state, in the time that the gas pressure in cylinder reaches certain atmospheric pressure, air cylinder tie rod outwards moves left, and drive the claw of thread tension releasing disc to be moved to the left, claw and upper thread tension disc close contact also promote two upper thread tension discs simultaneously and unclamp and make upper thread in loose ends state, the control of loose ends time is by automatically controlled, electronic valve, electric eye, coordinate this action. there is certain defect in the disclosed technical scheme of this utility model: each type need design a set of thread-loosening device, causes cost to increase and the wasting of resources.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of adjustable overedger thread-loosening device is provided, and the poke rod by an adjustable width is to adapt to existing different overedger.
The disclosed technical scheme of the utility model is: a kind of adjustable overedger thread-loosening device, comprise loose ends device frame, and thread tension releasing disc, two fixed feet and overedger body that cylinder loose ends device frame arranges are affixed; The cylinder body of cylinder and loose ends device frame are affixed, and the piston rod of cylinder and the left end of thread tension releasing disc are affixed; The first slotted hole is set on thread tension releasing disc, screw fixedly makes the thread tension releasing disc can be with respect to loose ends device frame left and right displacement through the first slotted hole and loose ends device frame, it is characterized in that: described thread tension releasing disc is divided into left half and right half, left half and right half are all with poke rod separately, the right-hand member of left half arranges the second slotted hole, the left end of right half arranges the 3rd slotted hole, and at least two securing members are fixed together left half and right half through the second slotted hole and the 3rd slotted hole.
Compared with prior art, it is adjustable that the utility model has been realized poke rod width by simple structure, thereby realize the object that a kind of thread-loosening device can adapt to existing different overedgers.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described: a kind of adjustable overedger thread-loosening device, comprise loose ends device frame 2, thread tension releasing disc 7, two fixed feet 8 that cylinder 5 loose ends device framves 2 arrange are affixed with overedger body; The cylinder body of cylinder 5 and loose ends device frame 2 are affixed, and the left end of the piston rod of cylinder 5 and thread tension releasing disc 7 is affixed; The first slotted hole 70 is set on thread tension releasing disc 7, screw 6 fixedly makes the thread tension releasing disc 7 can be with respect to loose ends device frame 2 left and right displacement through the first slotted hole 70 and loose ends device frame 2, it is characterized in that: described thread tension releasing disc 7 is divided into left half 72 and right half 73, left half 72 and right half 73 are all with poke rod 71 separately, the right-hand member of left half 72 arranges the second slotted hole 74, the left end of right half 73 arranges 74 ', two trip bolts of the 3rd slotted hole 75 and through the second slotted hole 74 and the 3rd slotted hole 74 ', left half 72 and right half 73 is fixed together.
For different overedgers, can unclamp two trip bolts 75, then adjust the two-part relative position in left and right and be distance between left and right poke rod 71 to adapt to existing different overedger, after adjust position, locking trip bolt 75.
