Description
Technical field
The present invention relates to conveying mechanism field, particularly a kind of quantitative material feeder.
Background technology
Although spiral feeder Occupation coefficient is higher, systematic comparison is complicated, fluctuation of operating conditions can not feed back in time, and pressure feeding spiral is easily by impurity jam, even has screw shaft by the disconnected situation of card; For the existing problems weighing screw fixed-weight feeder, tooth-like constant feeder efficiently solves this problem, it with advanced technology, reliable and stable, cost performance is high, durable in use and famous, various production environment can be adapted to, but also there are the following problems: discharge nozzle is when occurring that air pressure is not enough or strengthen operational throughput, easily there is negative pressure appearance, make discharging not smooth.The poted assemblies of mixer designs not science because of filler seat, and does not also have upper press cover, so be difficult to reach complete sealing effectiveness, often occurs leaking material phenomenon, and not easy to operate when changing the filler in sealing layer.Because being provided with four blades altogether, uneven at whipping process feed, blade can cause the uneven error of larger feed due to distortion in a wherein blade operational process and affect feed precision.
Along with the progress of production technology, existing chain-plate type feeder can not meet the requirement of environmental protection and technique, because its conveying mechanism exposes in atmosphere, when carrying the material such as stone, rubble, the dust kicked up, dust pollute the environment, not only waste maintenance, clean human resources, nor be beneficial to the healthy of staff; Further, due to existing chain-plate type feeder work under bad environment, easily cause device damage, cause ageing equipment.In addition, because this chain-plate type feeder well cannot realize transport feed under the state of sealing, make the negative pressure equipment such as grinding machine, comminutor fully can not absorb the material of conveying mechanism conveying, cause the material contaminated environment be transferred further; Further, existing chain-plate type feeder cannot to its conveying material weigh in a sealed meter environment, operating personal can not effectively control convey materials number.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of quantitative feed mechanism, thus overcome existing feed mechanism can not the shortcoming of continuous and quantitative feeding.
For achieving the above object, the invention provides a kind of quantitative material feeder, comprise frame and actuating unit, comprising: hopper, it is located in described frame, and the material outlet place of hopper is provided with bin gate; Driver train, it comprises screw mandrel, slide block and rocker mechanism, described screw mandrel is connected with described actuating unit, described slide block and described screw mandrel engage each other, and to drive described slide block to move on described screw mandrel, described four-bar mechanism is connected with described slide block, described four-bar mechanism is connected with described bin gate, to control the unlatching of described bin gate with closed; And transmission device, described transmission device comprises driving band, and described belt conveyor is located in described frame, is positioned at the below at hopper material outlet place.
Preferably, in technique scheme, described four-bar mechanism comprises: rocking bar, and itself and described slide block are hinged; Strut bar, it is located in described frame; Pipe link, it is mobilizable is located on described strut bar, described pipe link one end and described rocking bar hinged; And bin gate pull bar, its one end is connected with described bin gate, and the other end of the other end and described pipe link is hinged.
Compared with prior art, the present invention has following beneficial effect: quantitative material feeder of the present invention, and mechanism is simple, and be combined with feed screw nut and four-bar mechanism two kinds of basic systems, easily safeguard, reliability is better.Can regulate the opening and closing of bin gate according to demand in real time, it is convenient to control the supply of material, and the material fallen is sent with belt conveyor, whole-course automation, without the need to artificial participation, greatly reduce labour intensity, belt conveyor is convenient to form automatic production line with other equipment simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural scheme of mechanism according to quantitative material feeder of the present invention.
Fig. 2 is the partial enlarged drawing of A place driver train in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole specification sheets and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or component part, and do not get rid of other element or other component part.
As shown in Figure 1 to Figure 2, according to a kind of quantitative material feeder of the specific embodiment of the invention, comprise frame 1 and actuating unit, be motor 2, hopper 3 is located in described frame 1, and the material outlet place of hopper 3 is provided with bin gate 4.Driver train comprises screw mandrel 5, slide block 6 and four-bar mechanism 7, described screw mandrel 5 is connected with motor 2, and slide block 6 to be located on screw mandrel 5 and to be engaged each other with it, motor 2 drives screw mandrel 5 to rotate, engage each other transmission by screw mandrel 5 and slide block 6, to drive described slide block 6 to move on described screw mandrel 5, described four-bar mechanism 7 is connected with described slide block 7, described four-bar mechanism 7 is connected with described bin gate 4, by the slip of slide block 7, change the motion of four-bar mechanism 7, and then control the unlatching of described bin gate 4 and close.Transmission device, comprises driving band 8, and belt conveyor 8 is located in described frame 1, is positioned at the below at hopper 3 material outlet place.For being seen off by the material fallen within belt conveyor, transmit material.
Preferably, described four-bar mechanism 7 comprises: rocking bar 71, strut bar 72, pipe link 73 and bin gate pull bar 74.Rocking bar 71 is hinged with described slide block 6.Strut bar 72 is located in described frame 1.Pipe link 73 is mobilizable to be located on described strut bar 72, the middle part of pipe link 73 with support by 72 hinged, described pipe link 73 one end and described rocking bar 71 hinged, the other end and bin gate pull bar 74 hinged.Bin gate pull bar and bin gate 4 hinged.
The workflow of quantitative material feeder of the present invention is as follows:
Before feeding, bin gate should be in closed condition, motor drives screw mandrel to rotate, and screw mandrel makes slide block pass to the direction away from motor, and rocking bar jacking side link overturns around the hinge-point with strut bar, the other end of side link pulls bin gate pull bar that bin gate is closed, and now belt conveyor remains static.
Material is added in the middle of hopper, first belt conveyor starts, subsequently motor action, and screw mandrel drives slide block to the left slippage of motor, rocking bar pulls down side link, therefore at the effect discharge door pull bar of side link, bin gate being opened, material falls on belt conveyor and is transported, and suitably regulates the number of turns that screw mandrel turns over, that is the distance of slide block movement, just the size of adjustable hopper opening, thus the speed regulating feed
