Description
Technical field
The utility model belongs to technical field of knitting machinery, particularly single electromagnetic needle selector.
Background technology
The slide cam selector used on the computer seamless underclothes knitting machine at present is the ceramic slide cam selector of piezoelectricity, and it is to make piezoelectric ceramic piece produce distortion by generating positive and negative voltage, thereby the band cutting blade moves up and down, directly radial push selection piece or get out of the way selection piece and carry out needle selection.In the course of the work, blade directly contacts selection piece can produce friction, thereby causes blade and selection piece wearing and tearing.Simultaneously, because the slide cam selector volume is large, make selection piece and syringe height higher, receive during motion that resistance is also larger.
Summary of the invention
The purpose of this utility model is single electromagnetic needle selector that a kind of volume is little in order to provide, the syringe height is lower, the resistance of motion is little.
For this reason, the technical solution of the utility model is: single electromagnetic needle selector is characterized in that: it comprises slide cam selector seat, induction panel seat, slide cam selector tablet, spring bearer plate, permanent-magnet steel, pressing plate and socket; Described slide cam selector seat has a U-shaped groove, and described induction panel seat is placed in the U-shaped groove of slide cam selector seat; Described slide cam selector tablet is arranged on the induction panel seat, and described slide cam selector tablet below has a straight pin; Have the magnetic induction district in the middle of described slide cam selector tablet, both sides are adsorption zone; The rear, magnetic induction district of described slide cam selector tablet has a needle selection magnetic pole; Described needle selection magnetic pole has an iron staff near an end in magnetic induction district, and the other end has one every the magnetic copper rod; Described permanent-magnet steel, socket and pressing plate are fastened on slide cam selector tablet top by mounting screw; Be connected with a binding post on described socket; Described tablet base rear end has two through holes, in a through hole, has an adjusting washer (disk) and adjustment screw; Be provided with spacing compression spring and stop screw in another through hole, described spring bearer plate is fixed on the outside of spacing compression spring place through hole by stop screw.
Be provided with a permanent-magnet steel on the utility model, and permanent-magnet steel makes the slide cam selector tablet become a band magnetic part magnetization of slide cam selector tablet; Under programme-control, when single electromagnetic needle selector is not switched on, the slide cam selector tablet is adsorbed in adsorption zone and magnetic induction district by the spring needle bottom, makes the spring needle bottom shift out needle tray, and there is the weak magnetic that is enough to adsorb spring needle in now magnetic induction district.When single electromagnetic needle selector energising, produce opposing magnetic field; Under the effect of opposing magnetic field, the magnetic at place, magnetic induction district is weakened, is not enough to adsorb the spring needle bottom; This makes spring needle break away from the slide cam selector tablet, and return needle tray and move upward, thus the eedles that the promotion level is arranged, the knitting needle bottom that makes eedles will not participate in braiding pushes needle tray, thereby realizes the needle selection braiding.Two through holes that tablet base rear end of the present utility model arranges, one coordinates for the straight pin arranged with front end the operating position of regulating single electromagnetic needle selector, and another is spacing for single electromagnetic needle selector; The needle selection end of described needle selection magnetic pole is set to iron staff, and the other end is set to every the magnetic copper rod, and this makes the magnetic of needle selection end strengthen.The beneficial effects of the utility model are: control circuit is simple, be convenient to install; Volume is little, and the multichannel needle selection can be installed, and improves and way is installed and can realizes multichannel jacquard weave function; Greatly increased the reliability of needle selection; Good heat dissipation effect in the course of the work; Cost is declined to a great extent.
The accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment of the present utility model, be described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is packing rearview of the present utility model;
Fig. 3 is packing front view of the present utility model.
The specific embodiment
Referring to accompanying drawing.The present embodiment comprises slide cam selector seat 1, induction panel seat 2, slide cam selector tablet 3, spring bearer plate 4, permanent-magnet steel 5, pressing plate 6 and socket 7; Described slide cam selector seat 1 has a U-shaped groove, and described induction panel seat 2 is placed in the U-shaped groove of slide cam selector seat 1; Described slide cam selector tablet 3 is arranged on induction panel seat 2, and described slide cam selector tablet 3 belows have a straight pin 9; Having 32， both sides, magnetic induction district in the middle of described slide cam selector tablet 3 is the first adsorption zone 31 and the second adsorption zone 33; 32 rears, magnetic induction district of described slide cam selector tablet 3 have a needle selection magnetic pole 14; Described needle selection magnetic pole 14 has an iron staff 15 near an end in magnetic induction district 32, and the other end has one every magnetic copper rod 16; Described permanent-magnet steel 5, socket 7 and pressing plate 6 are fastened on slide cam selector tablet 3 tops by mounting screw; Be connected with a binding post 8 on described socket 7; Described induction panel seat 2 rear ends have two through holes, have an adjusting washer (disk) 11 and adjustment screw 12 in a through hole; Be provided with spacing compression spring 10 and stop screw 13 in another through hole, described spring bearer plate 4 is fixed on the outside of spacing compression spring 10 place through holes by stop screw 13.
Be provided with a permanent-magnet steel 5 on the present embodiment, and permanent-magnet steel 5 makes slide cam selector tablet 3 become a band magnetic part 3 magnetization of slide cam selector tablet; Under programme-control, when single electromagnetic needle selector is not switched on, slide cam selector tablet 3 is adsorbed in the first adsorption zone 31, the second adsorption zone 33 and magnetic induction district 32 by the spring needle bottom, makes the spring needle bottom shift out needle tray, and there is the weak magnetic that is enough to adsorb spring needle in now magnetic induction district 32.When single electromagnetic needle selector energising, produce opposing magnetic field; Under the effect of opposing magnetic field, the magnetic at 32 places, magnetic induction district is weakened, is not enough to adsorb the spring needle bottom; This makes spring needle break away from slide cam selector tablet 3, and return needle tray and move upward, thus the eedles that the promotion level is arranged, the knitting needle bottom that makes eedles will not participate in braiding pushes needle tray, thereby realizes the needle selection braiding.Two through holes that induction panel seat 2 rear ends of the present embodiment arrange, one coordinates for the straight pin 9 arranged with front end the operating position of regulating single electromagnetic needle selector, and another is spacing for single electromagnetic needle selector; The needle selection end of described needle selection magnetic pole 14 is set to iron staff 15, and the other end is set to every magnetic copper rod 16, and this makes the magnetic of needle selection end strengthen.
