Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, an electromagnetic vibration feeding device comprises a feeding hopper 1, a balancing weight 6 and a feeding trough 4, wherein brackets 14 are arranged on two sides of the feeding hopper 1, dampers 7 are respectively arranged on the brackets 14 on the two sides, a damping support 2 is connected to the damper 7 on each side, and the bottom parts of the damping supports 2 on the two sides are connected with the balancing weight 6; the feeding groove 4 is positioned below the feeding hopper 1, two sides of the balancing weight 6 are connected with the upper end of the spring piece component 3, and the lower end of the spring piece component 3 is connected with two sides of the feeding groove 4; the rear end of balancing weight 6 is connected with installing support 8, and installing support 8 connects electro-magnet mount pad 9, sets up electromagnetic vibration device on electro-magnet mount pad 9 and the feed trough 4, and electromagnetic vibration device can drive feed trough 4 and do reciprocating motion back and forth.
The electromagnetic vibration device comprises an electromagnet 10 and an armature 11 which are matched, the armature 11 is fixed on the feeding groove 4, and the electromagnet 10 is fixed on the electromagnet mounting seat 9.
A cushion pad 13 is arranged on the armature 11.
The spring piece assembly 3 comprises two spring pieces, and a gasket 12 is arranged between the two spring pieces.
The discharge gate of feeder hopper 1 sets up baffle 5 that can adjust from top to bottom.
The shock absorber 7 and the shock absorption support 2, the shock absorption support 2 and the balancing weight 6, the spring piece assembly 3 and the feeding groove 4 are all fastened by bolts between the mounting support 8 and the electromagnet mounting seat 9.
The working process is as follows: the coil is electrified, the electromagnet generates pulse magnetic force, the whole system keeps certain amplitude, the feeding groove 4 vibrates at a certain angle, and the object is thrown upwards and moves forwards, so that the feeding effect is achieved.
The working principle is as follows: the material is arranged on the feeding groove 4 supported by the spring plate 3, the armature 11 is connected with the feeding groove 4 into a whole, the electromagnet 10 is composed of a coil and an iron core, the coil is wound on the iron core, and the unidirectional pulsating current after half-wave rectification flows through the coil, so that the electromagnet 10 generates corresponding pulse electromagnetic force. In the positive half cycle of alternating current, a pulsating current flows through the coil, and a pulsating electromagnetic suction force is generated between the iron core and the armature, so that the feeding groove 4 moves backwards, the spring piece deforms, and potential energy is stored; in the negative half period, no current passes through the coil, the electromagnetic force disappears, and the armature 11 separates from the electromagnet 10 by the spring force, so that the feed chute 4 moves forward, and thus the feed chute 4 continuously performs reciprocating vibration at the frequency of the alternating current power source.
