This electro -magnet action is sensitive, and dynamic response is fast, can improve the operating frequency of electro -magnet, and its power -weight ratio is big, and work heat stability can improve.
Description
Technical field
The utility model relates to a kind of electromagnet, particularly relates to a kind of electromagnet reading mechanism for electronic dobby.
Background technology
Electronic dobby is one of three big uncork devices of a kind of electromechanical integration loom, the part of the braiding signal of loom fabric as calculated machine is treated as shedding signal in real time and is added to the electromagnet solenoid that electronic dobby reads mechanism, the wobbling action that the electromagnetic force produced by electromagnet converts dynamic iron core to drives other transmission mechanism to carry out the lifting of harness frame in aweaving machine, finally realize the opening of warp on loom, the braiding of decorative pattern.
At present, there is following defect in the electromagnet of use: be first the version that after electromagnet adopts U-shaped iron core, unicoil and coil electricity, armature swings around axle, and energy consumption is large, and temperature rise, processing thermal stability is poor.Secondly, U-shaped iron core, unicoil add the version that armature swings around axle and cannot increase substantially electromagnet operating frequency.
These problems affect above-mentioned to the raising of production efficiency and loom production capacity, meanwhile, the poor raising also having influence on fabric quality of work of electromagnet thermal stability.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of working stability of realistic production requirement, the electromagnet reading mechanism for electronic dobby that operating frequency can obviously promote.
The technical solution of the utility model is such: the electromagnet reading mechanism for electronic dobby, the dynamic iron core comprising hollow electromagnetic coil, permanent magnet and be arranged at swingably in hollow electromagnetic coil, described permanent magnet is arranged on the outer wall of hollow electromagnetic coil, and is in the swinging plane of described dynamic iron core.
Further, described hollow electromagnetic coil comprises hollow member and coil, and described coil winding is in hollow member, and described dynamic iron core is arranged in hollow member, and lower end and the hollow member of described dynamic iron core are hinged.
Further, comprise housing, described hollow electromagnetic coil and housing fixed-link, described housing is provided with a side opening, and described dynamic iron core stretches out housing by opening.
Preferably, the banking stop of limitary retention iron core amplitude of fluctuation is established in described hollow electromagnetic coil both sides.
Preferably, described housing is U-shaped, and described hollow member cross section is rectangle.
The advantage of technical scheme provided by the utility model is, employing is energized by solenoid and the electromagnetic force Direct driver of permanent magnet generation electromagnet resultant magnetic field moves iron core swing and drives the drive disk assembly of reading mechanism, be active in one's movements, dynamic response is fast, thus improves the operating frequency of electromagnet.Power-weight ratio is large, and under same electrical magnet overall dimension, drive current is little, and electromagnet heat condition improves, and work of electromagnet thermal stability is improved.Electromagnet structure is simple, and good manufacturability, reliable operation, cost is suitable with U-shaped electromagnet.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Refer to Fig. 1 and Fig. 2, the electromagnet for electronic dobby reading mechanism involved by the utility model comprises the housing 7 of a U-shaped.The hollow electromagnetic coil 9 of a square-section is set in U-shaped housing 7, between the bottom of hollow electromagnetic coil 9 and housing 7, pad 2 is set.Hollow electromagnetic coil 9 comprises the hollow member 1 of square-section, and coil 8 is wound in hollow member 1.The dynamic iron core 4 of cross shape is arranged on hollow member 1 inside, stretches out the open side of U-shaped housing 7, and one end of dynamic iron core 4 is hinged by rotating shaft 3 and hollow member 1, makes dynamic iron core 4 be able to swing in hollow electromagnetic coil 9.At arranged outside permanent magnet 6 of hollow electromagnetic coil 9, permanent magnet 6 and dynamic iron core 4 swinging plane are in same plane, and near the openend of U-shaped housing 7, the banking stop 5 of knuckle is set outside two of hollow electromagnetic coil 9 in addition respectively, for limiting the amplitude that swings of dynamic iron core 4.
Composition graphs 3 to Fig. 5, this electromagnet adopts external switch power supply 10 and controls through external electrical switch 11, and electronic switch 11 is by the shedding signal controlling break-make of electronic dobby.48 volts of voltages that Switching Power Supply 10 exports are added to the two ends of coil 8 through electronic switch 11, when without shedding signal, electronic switch 11 is opened, coil 8 no power, now do not generate an electromagnetic field, in electromagnet magnetic circuit, only there is the magnetic field of permanent magnet 6, under the magneticaction in permanent magnet 6 magnetic field, dynamic iron core 43 swings around the shaft to the direction of permanent magnet 6 side, and dynamic iron core 4 does not drive other drive disk assembly of electronic dobby to carry out the lifting of harness frame in aweaving machine; When shedding signal is added to electronic switch, electronic switch 11 is connected, 48 volts of voltages are added to coil 8 two ends and produce the electromagnetic field contrary with permanent magnet 6 magnetic direction, and this electromagnetic field intensity is greater than the magnetic field of permanent magnet 6, therefore under the magnetic field force effect of the resultant magnetic field in electromagnetic field and permanent magnet 6 magnetic field, dynamic iron core 43 swings around the shaft to the direction of departing from permanent magnet 6, and the now swing of dynamic iron core 4 drives other drive disk assembly of electronic dobby to complete the lifting of harness frame in aweaving machine, the opening of warp thread.Like this by shedding signal controlling, the braiding being realized loom pattern fabric by the continuous reciprocally swinging of the dynamic iron core 4 of this electromagnet.
