Summary of the invention
Task of the present utility model is to provide a kind of blade abrasion and even crooked situation of preventing effectively to take place and use and guarantee the reliable needle selection device of needle selection.
Task of the present utility model is finished like this, a kind of needle selection device, it comprises pedestal, the solenoid fixed head of the both sides of a pair of length direction that is fixed on pedestal with corresponding to each other, be located at the solenoid on each solenoid fixed head, be fixed on the pedestal top and the circuit board that is electrically connected with solenoid, be installed in the blade that on the circuit board and interface that be electrically connected with circuit board and one group of hub setting activate at the iron core of the power supply magnetic coil that equates with quantity described solenoid the pedestal bottom, characteristics are: be installed with a blade bearing in the bottom of described pedestal, the spaced apart insert groove that equates with the quantity of described blade that is provided with on the blade bearing, the top extension of described blade constitutes connecting pin, on connecting pin, be installed with a protective jacket, protective jacket is corresponding in the described insert groove, and on protective jacket, be extended with an electromagnet base, be embedded with electromagnet on the electromagnet base, electromagnet is corresponding with described iron core.
In a specific embodiment of the present utility model, the middle part of the length direction of described protective jacket offers one first axis hole, and spaced apart second axis hole that is provided with in the bottom of the corresponding wall body of the length direction of described pedestal, described protective jacket insert second, first axis hole by bearing pin and hub setting in cantilever state in the bottom of pedestal.
In another specific embodiment of the present utility model, described protective jacket is made by nonmetallic materials.
Go back in the specific embodiment of the present utility model, described nonmetallic materials are nylon or plastics.
In another specific embodiment of the present utility model, described nonmetallic materials are nylon.
The advantage of technical scheme provided by the utility model is: owing to constitute connecting pin and be installed with protective jacket on connecting pin on the top of blade, protective jacket is corresponding to insert groove, thereby can avoid the top of blade directly to contact effectively with blade bearing, play the phenomenon that prevents blade abrasion and even bending, guarantee the service life of blade and the reliability of needle selection.
Description of drawings
Accompanying drawing is a specific embodiment structure chart of the present utility model.
The specific embodiment
Ask for an interview accompanying drawing, the pedestal 1 that has provided a plate hanger structure in the accompanying drawings and be rectangle substantially, each fixes one piece of solenoid fixed head 2 with first screw 21 in the corresponding both sides of the length direction of this pedestal 1, is fixed with solenoid 3 in 2 sides towards pedestal 1 of each solenoid fixed head.In the present embodiment, although illustrated on each solenoid fixed head 2, to be installed with four solenoids 3, obviously should not be subjected to illustrating the restriction of quantity.Top at pedestal 1 is installed with a circuit board 4 with second screw 41, is installed with an interface 5 on circuit board 4, and interface 5 is electrically connected with circuit board 4, and circuit board 4 is electrically connected with solenoid 3.Constitute a blade cavity 12 in the bottom of pedestal 1, be installed with a blade bearing 6 corresponding to the position of blade cavity 12 by means of the corresponding wall body of the length direction of pedestal 1 bottom, the shape of cross section of this blade bearing 6 takes the shape of the letter U, shown in accompanying drawing, on the corresponding wall body of the length direction of the bottom of pedestal 1, offer screw hole 13, revolve and screw hole 13 is fixed on blade bearing 6 bottom of pedestal 1 by the 3rd screw 62, by 6 pairs of described blade cavity 12 sealings of blade bearing, and the insert groove of being offered on the length direction of blade bearing 6 61 communicates with blade cavity 12.
Please continue to see accompanying drawing, the utility model recommends the top of each blade 7 that one group of quantity equates with described solenoid 3 to constitute connecting pin 71, on connecting pin 71, be installed with material and be preferably the protective jacket 8 of nylon, extend at an end of protective jacket 8 and to constitute an electromagnet base 81, be embedded electromagnet 811 in the cavity volume of electromagnet base 81, electromagnet 811 is corresponding with the iron core 31 of aforesaid solenoid 3.Shown in accompanying drawing, protective jacket 8 is corresponding in the aforesaid insert groove 61.Offer first axis hole 82 that connects at the middle part of the length direction of protective jacket 8, on the wall body of the corresponding both sides of the bottom of pedestal 1, offer second axis hole 11 that equates with the quantity of blade 7, with bearing pin 83 pass second, first axis hole 11,82 with protective jacket 8 hub settings on pedestal 1, more particularly, take blade 7 hub setting in cantilever state on pedestal 1 by protective jacket 8, the bottom of blade 7 is stuck in insert groove 61 and the pin of the knitting needle 9 of computer plain flat knitter and calls in person 91 corresponding.
When computer plain flat knitter is worked, head moves back and forth about producing according to the setting of program, in the time will making a certain group of being positioned on the needle plate or a few groups of knitting needles 9 enter duty selectively, then give corresponding needle selection device to signal by the control system of computer plain flat knitter, also be solenoid 3 energisings of these needle selection devices, produce magnetic field, thereby by 811 effects of 31 pairs of electromagnet of iron core, blade 7 produces beat, blade 7 corresponding to the pin heel 91 of knitting needle 9 is allowed to a side-sway, at this moment, since knitting needle 9 broken away from blade 7 control and on lift and enter duty, drive required knitting needle 9 by the triangle on the head of computer plain flat knitter and participate in braiding, vice versa.Owing to be provided with protective jacket 8 on the blade 7, and protective jacket 8 is corresponding to the insert groove 61 of blade bearing 6, thereby avoided the rigidity contact wear of blade 7 with blade bearing 6, protected blade 7 effectively, makes and obtained ultimate attainment prolongation in service life of blade 7.
