Description

Vertical vibrating feeder

The utility model relates to vibrating feeder, especially relevant with the powder or granule material feeder, it is widely used in the proportioning materials system of mine, refractory material, carbon element, cement, glass and food service industry, and normal and follow-up automatic weighing system cooperating, automation, high precision and high efficiency are finished proportioning materials.

Existing vibration material feeder; for example open introduce on the clear 55-101534 communique such the Japanese Patent spy; usually adopt Vidacare corp; for example be used as the actuating device of described feeder vibration blanking valve with a kind of electric pushrod; because this electric pushrod provides the reciprocal drive actions of a horizontal direction; this action needs by a series of link components; above-mentioned valve energy is vertically moved and form valve and open and close; because the transmission link of this connecting rod mechanism transmission is too much; and exist inevitably and the inconsistent power of blanking valve sliding motion direction; thereby usually can make described valve action dumb or even stuck; in addition; this structure is because when each start or shutdown; that a kind of state that often makes the subtle blanking valve of people be in out on earth or close; thereby often cause and dash material; it is a large amount of materials gravity flow and down or do not have an out-of-control phenomenon such as material; in addition; this employing electric pushrod also is not easy to adopt in feed proportioning system microcomputer to answer a pager's call and controls as the actuating device of blanking valve.

Therefore the utility model is exactly to propose a kind of vertical vibrating feeder that adopts air control unit to be used as the actuating device of above-mentioned vibration blanking valve for overcoming above-mentioned these shortcomings, owing to adopt pneumatic actuating device, the mechanical drive link of valve actuating device is reduced, simple in structure, valve action is reliable, control because of described pneumatics adopts electromagnetic valve usually, therefore adopt device of the present utility model, also be convenient in feed proportioning system, adopt system controlled by computer.

The vertical vibration material feeder of the utility model comprises an osed top feeder housing, one vertically is positioned at the barrel of giving of housing middle part substantially, one sleeve-type feed valve, the socket of sliding mutually of one end and the described lower end of giving barrel, one oscillatory type blanking assembly, its top is a bullet shunting disk, the lower end of this cone part and above-mentioned feed valve contacts, its underpart is one to be fixed on the electrodynamic vibrator on this cone shunting disk lower end, visit this vibration blanking assembly and flexibly be bearing in top in the housing of feeder by elastomeric element, opening of this sleeve-type feed valve, close, drive with the pneumatic actuating device that is positioned on the feeder housing, this strength actuating device comprises that at least one pair of is positioned at above-mentionedly to be given the barrel both sides and is parallel to the pneumatic working cylinder that this installs for the barrel axial line, by the pneumatic power drive parts described working cylinder and described sleeve-type feed valve is formed and is in transmission connection.

The utility model is described in further detail below by embodiment and with reference to accompanying drawing.

Fig. 1 to Fig. 5 schematically illustrates the constructional drawing according to the vertical vibrating feeder of an embodiment of the present utility model.

Fig. 6 is the mechanism's composition diagram that schematically illustrates traditional vertical vibrating feeder.

Fig. 2 is the cutaway view along Figure 1A-A line, 11 is the osed top feeder housing of vertically placing, 1 for vertically being positioned at the barrel of giving of housing 11 cardinal principle middle parts, 2 is sleeve-type feed valve, its upper end and the lower end formation slip socket of giving barrel, 3 is the cone shunting disk, the lower end of its cone part and feed valve 2 contacts, 4 are the electrodynamic vibrator on the lower end that is fixed on cone shunting disk 3, thereby constitute above-mentioned vibration blanking assembly;

6 and 6 ' be that a pair of roughly symmetry is positioned at the both sides to barrel 1, and be parallel to the pneumatic working cylinder that is installed in for the tube axial line on the housing 11, and be connected with the flange assembling that on feed valve 2, forms by the pneumatic power drive parts of forming by piston rod, nut, pipe link respectively, has piston in the working cylinder 6 of one side, the other end of the piston rod 7 that links to each other with this piston has screw thread, one of pipe link 9 also has screw thread, and connect piston rod 7 and pipe link 9 by nut 8, be to regulate for the ease of the installation of 2 at strength actuating device and feed valve;

Fig. 3 is the cutaway view that schematically illustrates along Figure 1B-B line, by spring members 12, spring perch 13 and suspension rod 14 constitute one group of elastic parts, with four groups of such elastic partss, to vibrate blanking assembly (3,4) flexibly be installed in the top of housing 11, the view that Fig. 5 sees for the C direction from Fig. 3.Fig. 4 amplifies expression spring members 12 and spring perch 13 and the mounting structure of suspension rod 14 on housing 11 for signal.

Fig. 6 schematically illustrates a kind of structure of traditional vertical vibrating feeder, 20 expressions drive the electrical motor of the Vidacare corp of feed valve up-and-down movement, 21 is reciprocating electronic awl bar, 22 is connecting rod mechanism, electronic awl bar 21 makes sleeve-type feed valve obtain the driving of up-and-down movement by connecting rod mechanism 22, the structure of the other parts of this device is the same substantially with the utility model device, so no longer be described in detail.

Below the effect and the effect of the utility model device are done further narration.

Pneumatic actuating device adopts electromagnetic valve to control usually, working cylinder 6 and 6 ' dispose respectively a pair of position four-way solenoid valve (not shown), can guarantee that by making such electromagnetic valve synchronous working the piston rod of the left and right sides drives feed valve 2 simultaneously and rises or decline, thereby form feed valve opening 5, in addition, described working cylinder can also adopt the adjustable pneumatic working cylinder of piston stroke, its regulative mode is simpler, generally be provided with and regulate the stroke that the bolt (not shown) limits cylinder piston by top above working cylinder, thereby reach the aperture of regulating the feed valve, in addition, can be by setting, when disconnecting power of electromagnetic valve, make the feed valve always be in closed condition, thereby make people can grasp the residing this moment state of feed valve.

Find out the utility model device thus owing to adopt the mechanism of pneumatic actuation feed valve, make driving mechanism structure simple, valve starts reliable operation, the general valve that can not produce blocks the out-of-control phenomenon that dashes material or gravity flow with material, in addition, owing to adopt pneumatic actuating device, and employing electromagnetic valve, and only need be switched on or switched off and control power of electromagnetic valve, thereby help in whole feed proportioning system adopting the control system of micro computer, and contrast the feed valve driver train of traditional electronic awl rod-type, because of at that time control content for making the electrical motor rotation or stop the rotation, as will controlled object be organized in the microprocessor control system and go the inevitable complexity of its structure, the factor of being disturbed is also more, is difficult for obtaining required degree of regulation.

In addition, because the utility model device is the top that vibration blanking assembly is lifted on housing 11 by described four groups of elastic partss, thereby make installation and maintenance become easy to machine, also because such elastic oscillating system that constitutes, by adjusting to the pre-compression force of spring members 12, can make the controlled or adjusting of resonance point of this elastic oscillating system, thereby this elastic oscillating system is used more effectively.

In addition, in above-mentioned each figure, the parts that identical symbolic representation is identical or same.
