Specific implementation mode
A kind of magnetic of the present embodiment keeps electromagnetic needle selector, as shown in Figure 1, 2, including main casing 1, the main casing 1 Fixed frame pedestal 4 and 8 single channel slide cam selectors 2 arranged side by side are inside installed, 1 surface of main casing passes through built in both sides Groove is equipped with cover board 3;It when assembly, the groove built in main casing 1 is first passed through by cover board 3 pushes to slide and be pressed into, then pass through cover board 3 Two threaded holes be connected using screw and main casing 1.1 top of main casing, which is equipped with, offers slide cam selector limit hole Front limit baffle 5, rear postive stop baffle 6.
The single channel slide cam selector 2 includes cutter head fixed block 22, cup-shaped shell 28 and iron core 27;The cutter head fixed block 22 tops are embedded to be equipped with cutter head 21, and 22 bottom of cutter head fixed block is embedded to be equipped with permanent magnet fixture block 24;The knife Shaft 23 is installed, the shaft 23 is movably arranged on main casing on the cutter head fixed block 22 between first 21 and permanent magnet fixture block 24 On body 1;The cutter head 21 is located at main casing after the slide cam selector limit hole for the front limit baffle 5 for offering slide cam selector limit hole Outside body 1;Be equipped in the permanent magnet fixture block 24 poles N permanent magnet 29 upper, that the poles S are under, the poles S in the upper, poles N under Permanent magnet 210, and the poles N are solid in permanent magnet 210 upper, that the poles N are under in permanent magnet upper, that the poles S are under 29 and the poles S Even;Therefore cutter head 21, cutter head fixed block 22, permanent magnet fixture block 24, the poles N are in permanent magnet 29 upper, that the poles S are under, the poles S in upper, N Permanent magnet 210 of the pole under is a small entirety, can be rotated around shaft 23.Iron is installed on the fixed frame pedestal 4 Core 27 is nested with cup-shaped shell 28 on the iron core 27, iron is set on the iron core 27 being located in cup-shaped shell 28 It is set with coil 26 outside iron core plastic sheath 25 on core plastic sheath 25, the iron core 27.The iron core 27 is by iron core plastics Set 25 is isolated with coil 26, while cup-shaped shell 28 is nested on iron core 27, and semi-surrounding lives coil 26.Have benefited from cup-shaped Shell 28 it is semi-open, the heat that coil 26 generates can timely and effectively be distributed, while can preferably completely cut off phase Interference caused by the closed loop magnetic field that adjacent single channel slide cam selector 2 generates, and facilitate two copper wire for drawing coil 26 to driving plate, and And this shape processing is easy, and it can be by metal plate around being formed, cost is relatively low.
A kind of magnetic of the present embodiment keeps electromagnetic needle selector, and the initial position when not working is as shown in figure 3, the wherein poles N exist Permanent magnet 29 of the upper, poles S under, in permanent magnet upper, that the poles N are under 210, the two are connected firmly together and by permanent magnet card for the poles S Block 24 is fixed and the two magnetizing direction is opposite;It is similar since magnetic keeps the iron core 27 in electromagnetic needle selector inherently to have magnetism Permanent magnetism volume property, starting stage iron core upper end show S grades, and lower end shows N grades, and iron core 27 exists to the left side poles N in the upper, poles S Under permanent magnet 29 there is repulsion, there is suction in permanent magnet 210 upper, that the poles N are under to the right side poles S, and due to permanent magnet card Block 24 connects firmly effect, so that the two is jointly subjected to an anticlockwise torque, therefore cutter head 21 is also by counterclockwise one A torque, and the effect of the front limit baffle 5 due to offering slide cam selector limit hole, so original state cutter head 21 is maintained at Limit right positions, that is, cutter head 21 abut the right side of the limit hole on the front limit baffle 5 for offering slide cam selector limit hole Wall.When electromagnetic needle selector is under reversed high pulse voltage, by applying different voltage directions, the magnetism of iron core 27 to coil 26 Variation be upper end N grades, lower end S grades, and the poles N in permanent magnet 29 upper, that the poles S are under and the poles S in permanent magnet upper, that the poles N are under 210 magnetism will not change, therefore cutter head 21 is abutted and opened to left side, that is, cutter head 21 with the clockwise oscillation of permanent magnet The left side wall of limit hole on front limit baffle 5 equipped with slide cam selector limit hole.State is as shown in Figure 4 at this time.Therefore at interval of A period of time gives a positive pulse voltage appropriate, then certain interval of time gives an appropriate negative pulse voltage, by giving Coil 26 applies different voltage directions, and needle selection cutter head 21 is made to swing to other side extreme position from side extreme position to carry out Needle selection.To control whether its external corresponding pattern bit is pressed into needle tray, to control whether knitting needle enters triangle, jacquard weave is realized.
The electromagnetic needle selector of the present embodiment uses independent 8 single channel slide cam selectors arranged side by side, and uses semi-open knot The heat that coil generates can timely and effectively be distributed, while can preferably completely cut off adjacent single channel by the cup-shaped shell of structure Interference caused by the closed loop magnetic field that slide cam selector generates, and facilitate two copper wire for drawing coil to driving plate, and this shape Simple processing can be suitable for magnetic and keep the application of slide cam selector, while reducing single channel needle selection as far as possible by metal plate around being formed Influence of the device shell magnetic loop to other several roads makes its reliability and stability higher.It is relatively low with cost, compact-sized, peace Dress is convenient, and heat dissipation is quick, the small feature of degree of disturbance.
