Abstract
The utility model provides an automatic thread trimming device of a reel foot machine and belongs to the technical field of reel foot machines. The automatic thread trimming device of the reel foot machine solves the problems that the stability of a thread separating action before a moving blade of an automatic thread cutting device of the existing reel foot machine cuts threads along an actual motion route is bad, therefore the thread cutting action can not be effectively accomplished and the like. The automatic thread trimming device of the reel foot machine comprises a rotating shuttle support and a pneumatic needle plate which is arranged on the rotating shuttle support. A stationary knife and a movable knife are fixed on the pneumatic needle plate in a stack-up mode. The movable knife is capable of driving a connecting rod component which rotates around the circumferential direction of the movable knife to be fixedly connected. The pneumatic needle plate is provided with a limit mechanism which is used for keeping the resultant force of the movable knife and the stationary knife. A rotating shuttle locating hook is arranged on the pneumatic needle plate and near the rotating shuttle. The automatic thread trimming device of the reel foot machine has the advantages of achieving a stable and reliable thread cutting action, guaranteeing service life of the thread cutting device, changing the installation method of the rotating shuttle locating hook, guaranteeing a rotating shuttle thread throwing position when threads are cut and improving stability of thread cutting.
Description
Technical field
The utility model belongs to rumble pin machine technology field, refers in particular to a kind of automatic thread trimming device of rumble pin machine.
Background technology
Rumble pin machine is a kind of Sewing machines of making the bottom of s trouser leg three crease crimpings such as jeans, casual pants.The less stable of separated time action before the automatic thread trimming device of present rumble pin machine, moving knife actual motion path trimming causes the trimming action effectively not finish.And in the actual use procedure, behind certain trimming number of times, the adhesive force between moving knife and the stationary knife weakens, even in normal separated time situation, often can occur effectively cutting off suture.The rotating shuttle location hook of external, because the rotating shuttle location hook is installed on the rotating shuttle support black skin, installation dimension is unstable, has changed the front and back position of rotating shuttle, the rotating shuttle line during to trimming is thrown the position and is exerted an influence, thereby is unfavorable for the stability of trimming.
Summary of the invention
The purpose of this utility model provides a kind of trimming stable performance, the automatic thread trimming device of reliable in action, effective rumble pin machine.
The purpose of this utility model is achieved in that
The automatic thread trimming device of rumble pin machine, comprise rotating shuttle support and the pneumatic needle plate that is located on the rotating shuttle support, it is characterized in that: stacked stationary knife and the moving knife of being fixed with on the described pneumatic needle plate, moving knife is fixedly connected with the link assembly that can drive its circumferential rotation, described pneumatic needle plate is provided with the position-limit mechanism that keeps moving knife and stationary knife adhesive force, and the nearly rotating shuttle place of described pneumatic needle plate is fixed with the rotating shuttle location hook.
In the automatic thread trimming device of above-mentioned rumble pin machine, described position-limit mechanism is: moving knife one side is provided with hold-down plate spring, and hold-down plate spring is fixed on the pneumatic needle plate, and hold-down plate spring is pressed in moving knife and stationary knife are close to mutually.
In the automatic thread trimming device of above-mentioned rumble pin machine, described moving knife one end is provided with blade, the other end and link assembly and fixes, and described hold-down plate spring is pressed in the middle part of moving knife.
In the automatic thread trimming device of above-mentioned rumble pin machine, described pneumatic needle plate is provided with the stationary knife tension adjustment screw.
The utility model compared to existing technology outstanding and useful technique effect is:
1, the utility model can guarantee the service life of cutting facility preferably realizing that the trimming action can be stablized, the reliable while.
2, trimming moving knife of the present utility model is realized accurate and effective separated time, has improved stability, the reliability of automatic shearing action.
3, the utility model has improved trimming moving knife and the trimming stationary knife applying cutter of automatic thread trimming device, thereby guarantees preferably the service life of cutting facility.
4, the utility model has changed the mounting means of rotating shuttle location hook, and the rotating shuttle line when having guaranteed trimming is thrown the position, thereby improves the stability of trimming.
Description of drawings
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model.
Fig. 2 is fundamental diagram of the present utility model.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
The automatic thread trimming device of rumble pin machine, comprise rotating shuttle support 1 and the pneumatic needle plate 2 that is located on the rotating shuttle support, stacked stationary knife 3 and the moving knife 4 of being fixed with on the described pneumatic needle plate, moving knife 4 is fixedly connected with the link assembly 5 that can drive its circumferential rotation, described pneumatic needle plate 2 is provided with the position-limit mechanism that keeps moving knife and stationary knife adhesive force, and the nearly rotating shuttle place of described pneumatic needle plate is fixed with rotating shuttle location hook 6.
Above-mentioned rotating shuttle location hook 6 directly is fixed on the pneumatic needle plate by screw, has avoided existing rotating shuttle location hook to be fixed on the installation dimension that causes on the rotating shuttle support black skin and deviation occurred, and the front and back position that has changed rotating shuttle is unfavorable for the problems such as stability of trimming.
Above-mentioned position-limit mechanism is: moving knife one side is provided with hold-down plate spring 7, and hold-down plate spring is fixed on the pneumatic needle plate, and hold-down plate spring is pressed in moving knife and stationary knife are close to mutually.Described moving knife one end is provided with blade, the other end and link assembly and fixes, and described hold-down plate spring is pressed in the middle part of moving knife.
Be laminated with stationary knife, moving knife, hold-down plate spring on the above-mentioned pneumatic needle plate, the three fits mutually, and wherein hold-down plate spring is pressed in the state of being close to that makes moving knife maintenance and stationary knife on the moving knife.
Assembling process of the present utility model is as follows: rotating shuttle location hook 6 usefulness rotating shuttle location hook hold-down screws 60 are fixed on the pneumatic needle plate 2, trimming stationary knife 3 usefulness stationary knife hold-down screws 30 are installed on the pneumatic needle plate 2, moving knife link assembly 5 is placed in the groove on the pneumatic needle plate 2, trimming moving knife 4 is placed on the pneumatic needle plate 2 and with moving knife link assembly 5 is connected, with moving knife axial screw 40 trimming moving knife 4 is installed on the pneumatic needle plate 2, behind the free gap of adjustment trimming moving knife 4 movable arbor position screw-nut 41 and movable arbor position screw threads are fastened, stationary knife is opened cutter adjustment screw 8 to be installed on the pneumatic needle plate 2, screw or unscrew stationary knife and open the adhesive force that cutter is adjusted screw 8 capable of regulating trimming stationary knifes 3 and trimming moving knife 4, moving knife hold-down plate spring 7 usefulness hold-down plate spring screws 70 are fixed on the pneumatic needle plate 2, and moving knife hold-down plate spring 7 is pressed on the trimming moving knife 4 at this moment.
