Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of structure of Electromagnetic Drive knitting needle needle selection device, as shown in Figure 1, 2, including：By Electromagnetic Drive component 6 (containing electricity
Permanent magnet 5 in Magnetic driving component), upper solenoid 41 (containing upper electromagnetic coil skeleton 31), lower solenoid 4 is (containing lower electromagnetic wire
Ring framework 3), silicon steel core 2, shell 8, base 1, needle jack 9, knitting needle 10 and control system composition.
Specifically, shell 8 is threaded connection and is fixed on base 1, and shell 8 first half endoporus is Electromagnetic Drive component
6 provide guiding, and shell 8 the latter half is upper solenoid 41, lower solenoid 4 provides installing space, and Electromagnetic Drive is knitted
Magnetic field between pin is shielded.It is provided with Electromagnetic Drive component 6, Electromagnetic Drive component 6 top is stretched out shell 8 and endured in shell 8
Faller gill 9 connects, and needle jack 9 top is connected with knitting needle 10；Knitting needle 10 promotes realization to move up and down by needle jack 9, and needle jack 9 is not with
Carry out packet with length to install.Knitting needle 10 is arranged in the needle tray of circular syringe, can move up and down, and knitting needle 10 adopts existing circle
Standard component on machine or straight-bar machines.Circular groove, the bottom circular groove of Electromagnetic Drive component 6 are arranged at the bottom of Electromagnetic Drive component 6
Permanent magnet 5 in interior setting Electromagnetic Drive component.The upper end that in shell 8, bottom is provided with hollow is the lower solenoid bone of concave station shape
Frame 3, is provided with lower solenoid 4, the concave station face of lower electromagnetic coil skeleton 3 and electromagnetism between lower electromagnetic coil skeleton 3 and shell 8
Drive member 6 bottom contacts.The silicon steel core 2 being arranged in shell 8 is connected on base 1 by the screwed hole on base 1, silicon
