Description
The utility model relates to a kind of knitting machine parts, specifically a kind of circular knitting machine electromagnetic needle selector.
We know that the needle selection device is the critical component of computer jacquard knitting machine, at present, both at home and abroad knitting industry needle selection device mainly contain that electromagnetic type, electromagnet and permanent magnet are hybrid, three types of piezoelectric ceramic types.Electromagnetic type needle selection device comprises dual mode, and a kind of electromagnet that adopts stepper motor to be transformed into utilizes the stepper motor both forward and reverse directions to rotate the action of finishing requirement; Another kind is the power that a direction is provided by electromagnet, and rightabout power is provided by spring or other external force, above-mentioned two kinds of electromagnetic type needle selection devices, and operating frequency is low, and parameter consistency is poor, volume is big, bad adaptability.The hybrid needle selection device of electromagnet and permanent magnet is used more at present, come to this a kind of as patent 932239668, it is by including electromagnet and permanent magnet, permanent magnet connects an end that transmits bar, transmit the bar other end and connect the needle selection cutter head, utilize the interaction of electromagnetic force and permanent magnetism power to finish the action of needle selection cutter head.The needle selection device of this structure is in order to meet the requirements of action moment, the electric current of solenoid and the field intensity of permanent magnet all can not be done too for a short time, so coil easily generates heat, easily mutual interference mutually between the electromagnetic component of permanent magnet and other groups and the permanent magnet, stability is bad, can not satisfy many-sided requirement.Piezoelectric ceramic type needle selection device is more advanced digitalized needle selecting machine, and its volume is little, and is in light weight, operating frequency height, but its cost height, and the life-span is short, is unfavorable for applying.
The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned prior art, provides a kind of compact conformation, the operating frequency height, working stability is reliable, long service life, the circular knitting machine electromagnetic needle selector that cost is low, it can form various different sizes, to satisfy the requirement of various dissimilar machines.
For achieving the above object, a kind of circular knitting machine electromagnetic needle selector, it includes housing, electromagnet, electromagnet center framework, needle selection cutter head and transmits bar, electromagnet armature and transmission bar one end flexibly connect, and transmit the bar other end and fixedly connected with the needle selection cutter head, it is characterized in that being wound with on the electromagnet core two coils, be provided with a pillar between two coils, public armature bearing is provided with a semi arch fulcrum in the middle of it on pillar, armature semi arch top is provided with a spacing fixed axis.
The utility model adopts double-coil electromagnet, and each coil is controlled separately, and armature is the part of electromagnet magnetic circuit, can be fulcrum with the pillar in the middle of unshakable in one's determination, swing as lever, thereby drive the action that the needle selection cutter head is realized positive and negative two directions, finish needle selection work.The utility model magnetic circuit is closed, and armature is the part of closed magnetic circuit, is again the lever that transmits electromagnetic force, under same output torque situation, winding volume can be very little, the utility model compact conformation, and volume is little, the functional reliability height, operating frequency height, low cost of manufacture.Can be combined into different size as required easily, different needle selection cutter numbers, the needle selection device of different needle selecting functions.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation.
As can be seen from Figure, a kind of circular knitting machine electromagnetic needle selector, it is provided with housing, electromagnet, electromagnet center framework 4, needle selection cutter head 1 and transmits bar 2.Transmitting bar 2 is processed by nonmagnetic substance, to avoid the needle selection cutter head to be magnetized, transmitting bar one end fixedlys connected with needle selection cutter head 1, the other end and electromagnet armature 3 plug-in types flexibly connect, its termination is provided with a draw-in groove 9, draw-in groove 9 inboards correspondingly are provided with two projectioies 8, and it can be half-cylindrical, also can be triangle or bulb-type.Armature 3 closely is inserted in the draw-in groove, can drive transmission bar and needle selection cutter head along rotating shaft 10 swings, realizes the needle selection action.Rotating shaft 10 can be fixed on the housing.
Be wound with two coils 6 on the utility model electromagnet core 5, each coil is control separately, in fact just constitutes two independently electromagnet.Be provided with a pillar 7 in the middle of the coil 6 on the iron core, pillar 7 is parts of two solenoid magnetic circuits, promptly is public magnetic conduction path.Pillar 7 upper supports are provided with public armature 3, and therefore, pillar 7 is again the supporting-point of public armature 3.Public armature 3 is by the good electric iron material processing of magnetic conduction, and elongated, one end and transmission bar 2 flexibly connect, and are provided with a semi arch fulcrum in the middle of the armature, and it contacts with pillar 7 end faces, is bearing on the pillar 7.Like this, public armature 3 can be swung around pillar 7 under the effect respectively of two coils, thereby drive transmission bar and needle selection cutter head are realized the motion of positive and negative two directions, realize circular knitting machine computer jacquard needle selecting function.
The utility model can be provided with a semi arch notch in order to increase armature movement reliability and sensitivity on the pillar 7, its arc radius is larger than the semi arch radius of armature 3 fulcrums.Also be provided with a spacing fixed axis on the top of armature 3 semi arch fulcrums, it can be processed by copper rod.During use, it just in time is pressed on the circular arc of armature 3, is used for spacing fixed armature.Spacing fixed axis can be fixed on the center framework 4.
The magnetic circuit of the utility model electromagnet is to be made of the good electric iron material of magnetic property, and is closed fully, and magnetic resistance is little, and magnetic conduction is reliable, parameter stability.Under the situation of same output torque, can reach the purpose that winding volume is little, electric current is little.Electromagnet armature is made the balance bar rod-type, has significantly reduced the rotary inertia of armature, helps improving rotational frequency.
The utility model compact conformation can be combined into various different sizes easily, different needle selection cutter numbers, the needle selection device of different needle selecting functions.Reliable in action, speed is fast, and low cost of manufacture is applicable to various circular knitting machine computer jacquard needle selections usefulness.
