Abstract
The utility model relates to knitting machinery, in particular to an electromagnetic needle selector that adopts improved permanent magnet materials, which consists of a needle-selecting cutting head, a permanent magnet and an electromagnetic coil. The permanent magnet is of an integral permanent magnet body, on which N and S poles exist on the magnetic end surface at the same time. The permanent magnet is fixed and connected with the needle-selecting cutting head, and the magnetic end surface corresponds to an iron core inside the electromagnetic coil. The knitting machinery uses one permanent magnet to replace two permanent magnets, and has N, S poles existing on the magnetic end surface of the one permanent magnet. The magnetism density of the N, S poles is same, and the magnetic force is equivalent, thus allowing the needle-selecting cutting head to swing stably with correct swinging location, and having no problems of inconsistencies of the two permanent magnets in shape, as well as reducing the requirements to the accuracy of permanent magnet installation.
Description
Technical field:
The utility model relates to Knitting Machinery, especially a kind of electromagnetic needle selector that uses the modified permanent-magnet material.
Background technology:
Needle selection cutter in the existing electromagnetic needle selector uses two block permanent magnets that are set up in parallel on the contrary by polarity to make its swing.Permanent magnet is to adopt the method magnetize to produce magnetic, if the shape of two block permanent magnets is slightly different, will cause that the density that magnetizes is inequality, magnetic force is inhomogeneous, causes the swing of needle selection cutter unstable, and swing position is inaccurate.In addition, when using two block permanent magnets, the installation accuracy of permanent magnet requires very high, if the installation site has error also can cause the position of needle selection cutter swing inaccurate.
Summary of the invention:
The utility model is intended to solve the problem that above-mentioned electromagnetic needle selector exists, and provide a kind of and can make that the swing of needle selection cutter is stable, swing position accurately and can reduce electromagnetic needle selector to the use modified permanent-magnet material of permanent magnet installation accuracy requirement.
The technical scheme that the utility model addresses the above problem employing is: a kind of electromagnetic needle selector that uses the modified permanent-magnet material, comprise needle selection cutter head, permanent magnet, solenoid, described permanent magnet is that the end face that magnetizes exists the whole permanent magnet at N, S the two poles of the earth simultaneously, it is fixedlyed connected with the needle selection cutter head, and its end face that magnetizes is corresponding with iron core in the solenoid.
Compared with prior art, the beneficial effects of the utility model are: use a block permanent magnet to replace two block permanent magnets, on the end face that magnetizes of this part permanent magnet, there are N, S the two poles of the earth, the magnetic density at N, S the two poles of the earth is identical, magnetic force equates, thereby make that the swing of needle selection cutter is stable, swing position is accurate, do not have the inconsistent problem of two block permanent magnet shapes, also reduced requirement the permanent magnet installation accuracy.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of electromagnetic needle selector that uses the modified permanent-magnet material, form by needle selection cutter head 1, permanent magnet 2, solenoid 3, there is the whole permanent magnet at N, S the two poles of the earth simultaneously in described permanent magnet 2 for the end face that magnetizes, one end of needle selection cutter head 1 is fixedlyed connected with permanent magnet 2, and the end face that magnetizes of permanent magnet 2 is corresponding with iron core in the solenoid 3.When solenoid 3 energising, end of iron core produces magnetic pole in it, and with permanent magnet 2 on an opposite polarity utmost point attract, thereby the swing of needle selection cutter.
Claims (1)
1, a kind of electromagnetic needle selector that uses the modified permanent-magnet material, comprise needle selection cutter head, permanent magnet, solenoid, it is characterized in that: permanent magnet is that the end face that magnetizes exists the whole permanent magnet at N, S the two poles of the earth simultaneously, it is fixedlyed connected with the needle selection cutter head, and its end face that magnetizes is corresponding with iron core in the solenoid.
