Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of frequency conversion single-candidate powder conveying device, as Figure 1-4, has feed room 1, has been horizontally set with dividing plate 10 in this feed room 1, in this feed room 1 be divided into upper stock chest 11 and under turn hopper 12.
Dividing plate 10 offers feed opening 101, this feed opening 101 is opened in the close edge of dividing plate 10, is beneficial to be staggered with the discharging opening 121 of below.Be movably equipped with push pedal 2 above dividing plate 10, this push pedal 2 preferably designs near the upper surface of dividing plate 10, is beneficial to performance pulverization with this.
Under turn hopper 12 bottom land on offer the discharging opening 121 be staggered with feed opening 101, under turn hopper 12 bottom land on be movably equipped with portable plate 3, this portable plate 3 and bottom land suitable and spinning movement (being separated with small space between the two) can be carried out.Around being laid with bottom discharge hole group 31 in the annular region corresponding with discharging opening 121 on portable plate 3, by the material hole of multiple same volume at certain intervals around setting.Corresponding discharging opening 121 place above portable plate 3 is provided with coaming plate 4, this coaming plate 4 is preferably in the sector structure covering first retainer scope, design is not sealed in its upper end, its upper end level is higher than the lower end of feed opening 101, the surface of its bottom surface and portable plate 3 is arranged in mutually fitting movably, and this bottom surface offers the top discharge hole group 41(corresponding with bottom discharge hole group 31 see Fig. 3-4).Under the below of corresponding feed opening 101 that turns on its cell wall of hopper 12 be provided with sensor 8, for for detecting the accumulation sensor being attached to down and turning hopper 12 inwall powder.
Apparatus of the present invention, by push pedal 2, the powder in upper stock chest 11 is effectively pulverized, some block can be contained after powder moisture absorption, upper stock chest 11 is while pulverize powder by push pedal 2, turn hopper 12 downwards on one side to carry, powder fills up down the bottom discharge hole group 31 of the portable plate 3 turned on hopper 12 bottom land, according to the ratio of portable plate 3 rotation number, by coaming plate 4, the powder of the single-candidate amount of setting is pushed to discharging opening 121 again, the defeated powder operation of continuous print single-candidate can be carried out like this; And for during to postorder injection equipment conveying cleaning material, can well prevent block from blocking shower nozzle problem.Simply can be controlled the speed of powder single-candidate conveying by the rotative speed adjusting portable plate 3, namely realize the defeated powder operation of frequency conversion type single-candidate.
Preferably, discharging opening 121 is connected with mixing mechanism 72 via duff pipe 71, and duff pipe 71 is provided with dry ice delivery pipe 74.Under turn hopper 12 cell wall be provided with through to the air intake 73 in coaming plate 4, this air intake 73 passes into in coaming plate 4 for carrying dried compressed air.Dry air flows along coaming plate 4, turns hopper 12 under utilizing coaming plate 4 that air is turned under not dispelling to import under the prerequisite of powder in hopper 12, make frequency mixer 72 with under to turn hopper 12 internal pressure identical, therefore powder can not because of the back pressure of nozzle adverse current.In addition, due under coaming plate 4 compressed air application force, the powder be filled in bottom discharge hole group 31 is blown, and falls to being transported in discharging opening 121.
Preferably, push pedal 2 and portable plate 3 are assembled on main shaft 51 jointly, and this main shaft 51 is connected with and drives its servomotor 52 rotationally.Rotated by servomotor 52 drive shaft 51, thus drive push pedal 2 and the action of portable plate 3 synchronous rotary.This Synchronization Design, is beneficial to the two synchronous operation, guarantees that defeated powder operates, but also can save driving power, reduce costs advantage.The rotative speed of main shaft 51 is faster, and the rotative speed of push pedal 2 and portable plate 3 is faster, and the powder conveying amount of time per unit is larger, otherwise rotative speed is slower, and operational throughput is then less; The change of operational throughput is realized by changing rotative speed.
Specifically, powder conveying device has underframe 9, and servomotor 52 is installed in underframe 9.Feed room 1 is set up on underframe 9, be set up on underframe 9 preferably by a support tube portion 6, the output shaft of servomotor 52 up extends in support tube portion 6, bottom land is stretched out in support tube portion 6 in the bottom of main shaft 51, the bottom of this main shaft 51 is connected with the output shaft of servomotor 52, preferably carries out transition connection by coupler between the two.The design in support tube portion 6 is beneficial to and forms closed non-pollution structure, guarantees that device is reliable and stable, but also is beneficial to dismounting maintenance, also for the replacing of each main element provides convenience.The bearing arrangement for firm main shaft 51 is preferably also provided with, to strengthen Stability Analysis of Structures reliability in support tube portion 6.
Further, under to turn in hopper 12 every being provided with enclosed slot 122, run through extended for main shaft 51.Enclosed slot 122 is positioned at the inner side of bottom discharge hole group 31, and its upper and lower side is connected on dividing plate 2 and bottom land, to realize sealing effect, guarantees the cleanliness level of powder and avoids powder to pollute device, even affecting the problem of normal running.
Frequency conversion single-candidate powder conveying device of the present invention, its defeated powder method key step is as follows:
1) be installed in the powder in upper stock chest 11 while pulverized by push pedal 2, down turn hopper 12 by feed opening 101 and carry;
2) turn in hopper 12 under, along with portable plate 3 spinning movement, the powder fallen fills up the bottom discharge hole group 31 of portable plate 3 in real time, and suitably coordinate gear powder by coaming plate 4 afterwards, the single-candidate amount powder in the corresponding partial hole of bottom discharge hole group 31 transfers out via discharging opening 121.
Described 2) in step, by regulating portable plate 3 speed of rotation, can control by the defeated powder of simple realization frequency conversion type single-candidate.
Described 2), in step, also in coaming plate 4, pass into dried compressed air, this dried compressed air is led in bottom discharge hole group 31 via the top discharge hole group 41 on coaming plate 4 simultaneously.Dry air flows along coaming plate 4, turns hopper 12 under utilizing coaming plate 4 that air is turned under not dispelling to import under the prerequisite of powder in hopper 12, make frequency mixer 72 with under to turn hopper 12 internal pressure identical, therefore powder can not because of the back pressure of nozzle adverse current.In addition, due under coaming plate 4 compressed air application force, the powder be filled in bottom discharge hole group 31 is blown, and is beneficial to and completely falls to being transported in discharging opening 121.
In defeated powder process, sensor 8 also detects in real time and is attached to down the accumulating amount turning hopper 12 inwall powder, when accumulating amount exceedes setting value, stops down turning the operation of hopper 12 powder falling by relevant control mechanism controls powder.
The foregoing is only the preferred embodiments of the present invention, all equalizations done with the claims in the present invention scope change and modify, and all should belong to the scope of the claims in the present invention.
