Abstract
The utility model relates to a knife-holding type electromagnetic maintaining needle-selection device including a shell (1), n needle-selection units that are arranged on the shell (1). Each needle-selection unit comprises of a thimble blade (7) with a permanent magnet (5), a winding framework (2), an electromagnetic coil (3) on the framework (2), and an iron core (4) in the framework (2). The thimble blade (7) is arranged on a positioning plate (6) of shell (1), and a shielding cover (8) whose cross section is arc-shaped is arranged at the periphery of the electromagnetic coil (3). As the shielding cover which is easy to install is arranged at the periphery of the electromagnetic coil to shield external magnetic field, which can make the magnetic fields from electromagnetic coil make no mutual interference.
Description
Technical field
The utility model relates to textile machine, and specifically a kind of fencing type electromagnetism keeps needle selecting device.
Background technology
Existing needle selecting device generally adopts the fencing type electromagnetism to keep, and the action of its cutter head is to be controlled by coil electricity to have a permanent magnet on the cutter head, and a utmost point of magnet (N or the S utmost point) is near the iron core in the coil.Behind the coil electricity, just produced the N utmost point, the S utmost point at two of coil, the energising direction changes the N utmost point, the S utmost point at coil two, and it is exchanged mutually.The same sex according to magnetic is repelled each other, and there is a natural attraction between the sexes, and moving up and down of cutter head just can be controlled by the energising direction of coil.In actual use, because iron core generally adopts half-hard magnetic material, behind coil electricity, cut off the electricity supply, the N utmost point, the S utmost point that coil produces remain on iron core in meeting, but making the upset of its magnetic field and keeping having certain energy is that the coil electricity electric current must be greater than certain value, and the heat that so also makes coil produce is big.Behind the coil heating, it is big that resistance value becomes, and under the constant situation of voltage, electric current diminishes, and this moment, the magnetic induction intensity of coil weakened.Keep in the needle selecting device a plurality of coils being arranged generally at the fencing type electromagnetism, and the frequency that these a plurality of coils use is different, the use that has is frequent, the use that has is not frequent, uses frequent conduction time just long, and coil heating is just big, then the coil of heating produce magnetic field just a little less than, the magnetic field that generates heat coil little and produce is strong, disturbs thereby strong and weak magnetic field just has to produce, and makes the cutter head action not listen instruction and cause and make mistakes.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of can shield the fencing type electromagnetism maintenance needle selecting device that outer magnetic strength is disturbed.
Of the present utility model solving the problems of the technologies described above by following technical proposals solved: a kind of fencing type electromagnetism keeps needle selecting device, comprise housing, be located at n needle selection unit on the housing, each needle selection unit comprises thimble blade and the coil rack that has permanent magnet and is located at solenoid on the coil rack, is located at the iron core in the coil rack, the thimble blade is located on the location-plate of housing, and the periphery that is positioned at solenoid is provided with cross section and is circular-arc radome.
Above-mentioned radome is installed on the coil rack.
Above-mentioned radome is provided with several slits that is used to dispel the heat.
Above-mentioned needle selection element number n is 16.
Adopt the utility model of the technical program, its beneficial effect is, adds a radome at coil, and external magnetic field is shielded, and the magnetic field that makes coil produce can not produce the phase mutual interference.And radome is easy for installation.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Embodiment 1
Shown in Fig. 1,2,3,4, a kind of fencing type electromagnetism keeps needle selecting device to comprise that a kind of fencing type electromagnetism keeps needle selecting device, comprises housing 1, is located at 16 needle selection unit on the housing 1, and 16 needle selection unit vertically are located on the housing 1 side by side.Each needle selection unit comprises thimble blade 7 and the coil rack 2 that has permanent magnet 5, and be located at solenoid 3 on the coil rack 2, be located at the iron core 4 in the coil rack 2, iron core 4 is the cylinder-shaped iron cores that adopt half-hard magnetic material, and iron core 4 keeps the interior gap of 1mm with permanent magnet 5.16 thimble blades 7 vertically are located on the location-plate 6 of housing 1 side by side, in the periphery of solenoid 3, and cross section is installed on coil rack 2 is circular-arc radome 8.Radome 8 is made by ferrous material, has certain flexibility, is easy to be positioned on the coil rack 2, and the wiring board 11 that connects the electromagnet of being made up of coil rack 2, solenoid 3, iron core 4 is installed at housing 1 rear, and wiring board 11 is provided with connector 10.
Behind coil electricity, produced the utmost point, the S utmost point at two of coil, the energising direction changes the utmost point, the S utmost point at coil two, and it is exchanged mutually.The same sex according to magnetic is repelled each other, and there is a natural attraction between the sexes, and moving up and down of cutter head just can be controlled by the energising direction of coil.And this moment 16 coils because the power in the magnetic fields that the utilization rate difference produces, and then the interference that produces, by radome 8, external magnetic field is shielded, do not produce mutual interference, make the cutter head action not make mistakes by super work of normal instruction, and because radome 8 is non-enclosed, have certain gas permeability, help heat to distribute.
Embodiment 2
Shown in Fig. 5,6, a kind of fencing type electromagnetism keeps needle selecting device, its part is identical with embodiment 1,6 slits that are used to dispel the heat 9 just are set on radome 8, employing has the radome 8 in slit 9 can be easy to heat radiation more, and this moment the circular-arc of radome 8 its cross sections can approach circle more, shielding surface is bigger.
