Description

Push-pull type electric and magnetic oscillation feedway

The utility model relates to electro-vibrating feeder and load transfer device, and the weightless vibratory feed that claims in the weighing hopper, refers in particular to a kind of push-pull type electric and magnetic oscillation feedway.

In background technology, the various electric and magnetic oscillation feed load transfer devices of selling on the market are that alternating current is after half wave rectification, drive the crank motion that the spring be fixed on the housing and armature are done adhesive-release by electromagnet, utilizing the motion angle (20 °～30 °) of vibrating mass direction of vibration and mass transport direction that material is thrown to the direction of required conveying falls, the crank motion of not only throwing but also falling bounds forward and finishes mass transport.In this load transfer device, its cell body and armature weight, leaf spring weight, equivalent quality in the hopper material is formed total weight M1 jointly, and housing, the weight of iron core and coil, and half spring weight is formed total weight M2, connect total weight M1 and M2 by spring assembly, form the double-mass vibrating state,, just can finish the fast requirement of main frame delivery speed so require total weight M2 greater than M1, the equipment steel consumption is big, and electric property is operated in half-wave, and the unfavorable usefulness of another half-wave also is a kind of waste, directly work done again during electromagnetism work, to overcome the stress of spring earlier, and make spring energy-storage, and so that at electromagnet during at out-of-run another half-wave, spring work, so utilization rate of electrical is low, working gas gap can not excessive (being generally less than 2 millimeters), and Oscillation Amplitude is little, and double-amplitude has only 1.75 millimeter.Difficult sealing can not be operated in the occasion with explosion-proof waterproof requirement to reach whole sealing status in addition.

The purpose of this utility model is in order to overcome the weak point in the above-mentioned background technology, and develop a kind of push-pull type electric and magnetic oscillation feedway, there is not running gear when utilizing electromagnetism work, and characteristics such as higher reliability and easy operability are arranged, electromechanical integration, reach the efficient height, power saving, economize steel, and might replace the purpose of current traditional feed and load transfer device.

Technical solution of the present utility model is as follows:

Comprise assembling electromagnetic core 2 and wallet 3 in the housing 1, but the attaching parts 8 of assembling reciprocally swinging on the spring installation 6 in the housing 1, the armature 4 of attaching parts 8 one ends assembling is done adhesive-release with electromagnet and is cooperated, be characterized in, attaching parts 8 other ends also assemble another group armature 4 and do cooresponding release-adhesive with one group of electromagnet and cooperate, form by electromagnet in the housing 1 and armature 4 and to shake 9, about shake and 9 form adhesives and discharge reciprocal push-pull type electric and magnetic oscillation, make attaching parts 8 middle parts make vibrating transportation and cooperate hopper 7.

Be that the utility model adjoint is described in further detail below: referring to Fig. 1, about shake in 9 mounting structures all with, at housing 1 internal fixation " ∪ " shape electromagnetic core 2, be wound with electromagnetism iron wire bag 3 on the iron core 2, on housing 1 one end faces, assemble board-like spring installation 6 with screw 5, vibratile leaf spring device 6 middle parts, left and right sides screw 5 assembling connecting pieces 8, attaching parts 8 two ends fixed armatures 4 with about the electromagnet that shakes in 9 make adhesive-release corresponding matching, shake promptly 9 at alternating current after rectification, alternately adhesive and release, making attaching parts 8 be subjected to one pushes away one and draws reciprocal power, drive hopper 7 crank motions at attaching parts 8 middle parts, form push-pull type electric and magnetic oscillation principle of work.Whole 9 a usefulness iron shell and the rubber cushion of shaking is hermetically sealed, improves explosion-proof water repellant requirement.Referring to Fig. 2, shake in 9, housing 1 internal fixation " mountain " font electromagnetic core 2, be wound with line bag 3 on the iron core 2, four groups of spiral spring device 6 one ends are fixed on the housing 1, the other end is fixed on the attaching parts 8, and the fixing armature 4 in attaching parts 8 ends that can vibrate is back and forth done adhesive-release with electromagnet and cooperated, and principle of work is with the described unanimity of Fig. 1.Referring to Fig. 3, basic structure is ditto described, difference is the leaf spring device 6 that housing 1 one sides upper end can be swung with screw 5 assemblings, this leaf spring device 6 can be a big full wafer, also can be two groups or four groups of small pieces compositions, assembling connecting piece 8 on this spring installation 6, the resistance in the time of can reducing work of electromagnet like this.Referring to Fig. 4, this is vibrating feeder 12 work scheme drawings, by about shake and 9 be assemblied on the frame, form and to shake 9 up and down, like this in the utility model work, the attaching parts crank motion of an angle (20 °～30 °) is arranged, drive hopper 7 with an inclination angle up-and-down movement with horizontal surface, make feeder 12 continuously with certain flow feed, thereby reach the purpose of feed.Referring to Fig. 5, this is weighing hopper 13 work scheme drawings, and the Control work principle is with shown in Figure 4 the same, just by behind the check weighing of the sensor above the weighing hopper 13 again discharging finish weight-loss metering, the energising of control electromagnetism iron wire bag 3 reaches and controls weighing hopper 13 blankings.Referring to Fig. 6, this is a conveyer principle of work scheme drawing, also the same described the same, just several the utility model are installed on the frame 10 of conveyer 14, make attaching parts 8, promote hopper 7 and be synchronized with the movement up and down, make in the hopper 7 material throw and fall with the reciprocal up-and-down movement in certain inclination angle, advance in the spasmodic motion mode, finish the mass transport of long distance.Referring to Fig. 7, by the transformation or the frequency changer circuit of automatic or manual control circuit control, connect an a pair of line bag that shakes through positive and negative output circuit and form the loop, finish push-pull type electric and magnetic oscillation feedway.

Advantage of the present utility model and effect are as follows:

1, because the utility model adopts two head work of shaking, so electromagnetic circuit work becomes half Ripple is all-wave, and making its indirect work done is direct work done, without the energy-stored spring work done, only uses Spring assembly rises and connects and supporting role, has reduced the reactive loss of electric energy, power saving about 50 More than the %.

2, owing to adopt the symmetrical operation principle, make former equipment with power improve four times About the transfer efficiency ability, improve the feed ability of amplitude 4 millimeters (former 1.75 millimeters) Two times.

3, because electromagnetism work does not have relative friction running gear, so improved the service life of equipment.

4, owing to adopt the push-pull type principle of work, thus needn't consider in the original equipment that vibrational state concerns between the total weight M1 and M2, thus providing condition for alleviating weight of equipment, steel can be saved about 30%.
