The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
Embodiment:
With reference to Fig. 1,2, Computerized flat knitting machine electromagnetic needle selector of the present invention, comprises shell 1, and shell 1 is spliced by identical two halves, and it is made as aluminium alloy by non-magnet_conductible material.
With reference to Fig. 5,6, in shell 1, be provided with several permanent magnets 2, permanent magnet 2 is bar-shaped magnet, at two magnetic poles of each permanent magnet 2, is respectively equipped with the suction spindle magnetic inductive block 7 that is highly greater than permanent magnet 2, is provided with the needle selection magnetic conductor 3 of U-shaped and opening upwards between two adjacent permanent magnets 2 of length direction.
With reference to Fig. 3,4, needle selection magnetic conductor 3 opening upwards, vertical with permanent magnet 2, the end of permanent magnet 2 is corresponding to the hollow space of U-shaped needle selection magnetic conductor 3.Sheathed coil 5 on two magnetic conduction bars 4 of needle selection magnetic conductor 3, on the end face of the top of magnetic conduction bar 4, offer groove 6, the position of the groove 6 on two magnetic conduction bars 4 is identical, itself and direction are the direction (by the direction of magnetic conduction bar 4 lateral needle selection magnetic conductor 3 hollow spaces) that connects two magnetic conduction bars 4, thereby knitting needle is positioned at above two grooves 6 when motion simultaneously.
Two magnetic conduction bars 4 of needle selection magnetic conductor 3 lay respectively between two adjacent suction spindle magnetic inductive blocks 7, and adjacent suction spindle magnetic inductive block 7 is communicated with by magnetic conduction bar 4, produces continuous magnetic force.
Between suction spindle magnetic inductive block 7 needle selection magnetic conductors 3 and shell 1, be provided with not magnetic conduction wear-resistant material layer 9.
Also can be magnetic conduction bar 4 by its outside to the size of U-shaped needle selection magnetic conductor 3 hollow space directions and the width of above-mentioned suction spindle magnetic inductive block 7.
Filling epoxy resin plastics all between the suction spindle magnetic inductive block 7 of permanent magnet 2 both sides, in the hollow space of needle selection magnetic conductor 3 and groove 6, thereby form epoxy resin filling body 10 between the suction spindle magnetic inductive block 7 of both sides, the top end face of epoxy resin filling body 10 is lower than the top end face of suction spindle magnetic inductive block 7, needle selection magnetic conductor 3, to guarantee that knitting needle can firmly attract on slide cam selector when moving.
With reference to Fig. 7, the two ends of coil 5 connect respectively two pairs of switches 12, a pair of conducting is forward current, another is reversing the current to conducting, switch is electrically connected to power supply and a control chip 11, control chip 11 is built-in with control program, and it can, by receiving outside instruction or the judgement of self (built-in determining program), select conduct positive, reversing the current or disconnection.Switch is preferably mos pipe.
When electric current forward conduction, knitting needle can attract on slide cam selector and motion, when needs needle selection, control chip 11 gauge taps all disconnect or the reverse electric current of conducting, magnetic on cancellation needle selection magnetic conductor 3, the knitting needle that is positioned at groove loses its reliss and upsprings, and can carry out knitting.
Generally, when needs needle selection, disconnect all switches and get final product the magnetic on cancellation needle selection magnetic conductor 3.And after needle selection magnetic conductor length 3 service times, itself be also with magnetic, at this moment just need to pass into reverse electric current and carry out demagnetization.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
