Problems solved by technology

At present, there are only AC half-wave electromagnetic vibrating feeders in the world, which need to use rectifiers or filters to filter half of the AC waves, thereby generating periodic currents, thereby generating periodic magnetic fields. The core, the second half-wave magnetism disappears, and the iron core recovers under the action of the shrapnel until the next cycle. The disadvantage is that part of the electric energy is lost, the efficiency is poor, and the gap between the iron core and the coil is difficult to adjust. It cannot be used in heavy feeders. Use high failure rate
[0003] To sum up, the existing AC half-wave electromagnetic vibrating feeder has the problems of low power utilization rate, difficult adjustment of the gap between the iron core and the coil, not suitable for heavy-duty feeders, and high failure rate.

Abstract

The invention discloses a full-wave electromagnetic vibrating feeder. The magnetic armature core includes a magnetic armature core seat and a permanent magnet arranged in one body. The two magnetic poles formed by the permanent magnet on the iron core are respectively located at the ends of the E-shaped electromagnetic coil. There is an air gap in the groove and the groove of the E-shaped electromagnetic coil; the bottom of the first shrapnel is fixedly connected to the base through fasteners, and the top of the first shrapnel is fixedly connected to the trough bracket through fasteners; the bottom of the second shrapnel It is fixedly connected with the base through a fastener, and the top of the second elastic piece is fixedly connected with the trough support and one end of the magnetic armature core through a fastener, and the other end of the magnetic armature core is floating. The AC power acts on the whole working period, the magnetic poles of the E-shaped coil alternately change and interact with the armature iron core to generate absorption and repulsion, which drives the trough support to generate stable vibration, long service life, low power consumption, no need for rectifiers and frequency converters, and can be It is easily connected to the AC power supply and has good linear regulation.

Description

technical field [0001] The invention belongs to the field of material conveying equipment, in particular to a full-wave electromagnetic vibrating feeder. Background technique [0002] Vibrating feeders are commonly used to convey loose granular, powdered materials from a supply box, or along an extended hopper to convey raw materials or components from one input point to another output point. The existing conventionally used two-mass electromagnetic vibrating feeder generally includes a base and a vibration isolation spring that supports the base on the ground and isolates the feeder from the ground. The base is installed by a set of springs. A bracket, this group of springs can make the bracket do reciprocating linear motion under the excitation of the exciter. The exciter of this structure is usually electromagnetic, with an iron core and a coil installed on the base, and an armature is installed and fixed under the bracket, and There is an air gap between the coil and th...
