Description
Technical field
The utility model relates to a kind of electromagnetic needle selector of knitting machine self-sustaining magnetic force, and specifically a kind of magnetic core of high-remanence low-coercivity material that utilizes makes needle selection device knitting machine be operated in low-power consumption, the electromagnet slide cam selector of high-frequency self-sustaining magnetic force.
Background technology
In traditional knitting machine, the magnetic core of slide cam selector uses soft magnetic materials to do iron core, duty will have lasting electric current to produce magnetic force, the magnetic flux produced is lower between 40-60mT, thus reaction speed is slow, drive cutter head to swing highest stabilizing operating frequency generally between 100-150 Hz, and after coil deenergization, magnetic core magnetic force disappears at once! So operationally electromagnet coil needs long-term continuing to be energized, under long-term work, magnetic core temperature can constantly rise, and power consumption major part is all wasted in and keeps above magnetic force.Also the product of certain producer is had in order to High Voltage Power Supply when the caloric value reducing electromagnet have employed work, the type of drive of operating voltage is reduced when not working, although can partial heat be decreased but effect not obvious, the long-term work temperature that adds up is still higher, and magnetic core suction declines when low-voltage, produce dislocation when easily causing the needle selection cutter head of slide cam selector stressed and cause wrong flower phenomenon of weaving cotton cloth, cause unnecessary waste, so slide cam selector operationally low-power consumption in knitting machine, lower calorific value, high-frequency, high efficiency and high stability are knitting industry issues to be resolved always.
Summary of the invention
The purpose of this utility model is to provide a kind of electromagnetic needle selector of knitting machine self-sustaining magnetic force, it makes magnetic core by utilizing high-remanence low-coercivity material, magnetic core only needs operationally to pass to very short pulse drive signal, drive singal is turned off completely after action puts in place, because of the magnetic force that core material high remanent magnetism makes magnetic core keep stronger always, higher magnetic force makes the cutter head of slide cam selector swing maximum operating frequency can reach more than 200Hz, and because not needing to continue energising when slide cam selector works long hours, so power consumption is little, caloric value is low, and working stability, safe and reliable, environmental protection and energy saving.
Technical solution of the present utility model is based on housing, control circuit board, data-interface, magnetic core, needle selection cutter head, the magnetic core being characterized in described is the magnetic core of high-remanence low-coercivity material, the coil of magnetic core is connected with the pulse output interface of control circuit board by wire, the coil of positive or negative pulse signal to magnetic core is exported from pulse output interface after the knitting needle selection signal of control circuit board process data-interface input, make magnetic core reach strong magnetic saturation instantaneously, and produce at end face and keep N or S pole field.
The high-remanence low-coercivity material of the above magnetic core preferably can produce the high-remanence low-coercivity material of magnetic flux at 60-150mT when the direct current 24V pulse signal that the coil of magnetic core obtains.
Operation principle of the present utility model exports the coil of positive or negative pulse signal to magnetic core from pulse output interface after the knitting needle selection signal of the control circuit board process data-interface input of slide cam selector, magnetic core is made to reach strong magnetic saturation instantaneously, and produce N pole or S pole field at end face, at this moment two N poles on needle selection cutter head that one end relative with magnetic core are embedded in, the N pole that the permanent magnet of S pole will produce with magnetic core end face or S pole field produce the phenomenon of the attracting homopolar-repulsion of heteropole, needle selection cutter head is deflected centered by the installation shaft in housing, thus reach the action effect carrying out needle selection or not needle selection on knitting machine, because magnetic core is high remanent magnetism material, so only just export pulsed driving voltage changes magnetic core end face at that time polarity of the magnetic field state to coil when needing to change needle selection cutter head yawing moment, after operating state completes, utilize magnetic core remanent magnetism not need output drive signal again to keep cutter head deflection state, so just greatly reduce the energising total time of magnetic core, effective reduction magnetic core caloric value retains again enough magnetic field intensities simultaneously makes needle selection cutter head not easily produce misoperation, thus slide cam selector steady operation be there will not be weave cotton cloth wrong flower phenomenon.
The utility model has the advantages that rational in infrastructure, it can make the maximum operating frequency of slide cam selector reach more than 200Hz, and when working long hours, power consumption is little, heat is low, and working stability, safe and reliable, environmental protection and energy saving.
