Detailed description of the invention

Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, the present embodiment premised on technical solution of the present invention under implement, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.

Consult Fig. 1, Fig. 2 and Fig. 3, the dosing system of a kind of granule materials of the present invention, comprising: feed bin 1, feeder 2, feed supplement mechanism 3, gauging device 4.

The blanking port of feed bin 1 is rectangular, and the sidewall of feed bin 1 is provided with hopper wall vibrator 11, and hopper wall vibrator 11 is general only to work when removing tailing.The inlet point of feeder 2 is fixedly connected with the blanking port of feed bin 1, the inwall of the feeding-passage of feeder 2 has upper material-blocking plate 21 and lower material-blocking plate 22, their inclination angle is 135 ° and 45 ° respectively, the back side of lower material-blocking plate 22 is also with one piece of adjustable material-blocking plate 23, and adjustable material-blocking plate 23 is for adjusting maximum blanking flow; Feeder 2 is provided with the discharging slideway 26 of tilting, and the Slide-way tilt angle of discharging slideway 26 is 140 °, and material can lean on gravity with the landing of bulk flow mode nature on discharging slideway 26.

Consult Fig. 4, Fig. 5 and Fig. 6, the discharging slideway 26 of feeder 2 is also provided with the striker plate 24 of Telescopic movable, striker plate 24 has three exemplary position, and when extreme lower position, as Fig. 4, striker plate 24 does not affect the whereabouts of material; When maximum position, as Fig. 6, striker plate 24 can block the whereabouts of material completely; When middle diverse location, as Fig. 5, striker plate 24 can control discharging flow.Striker plate 24 electric cylinder 25 drives.In the rear end of discharging slideway 26, also have a rectangle opening, this perforate is the feeding mouth 27 of described feed supplement mechanism, and also have a length of tubing to be fixedly mounted on the slideway back side after this feeding mouth, this pipeline is exactly feed supplement mechanism feeding-passage 32.

Consult Fig. 7, feed supplement mechanism 3 is micro electromagnetic vibrating feeders, is positioned at the below of feeder 2 discharging slideway 26, and the hopper 31 of feed supplement mechanism 2 has good docking with its feeding-passage 32, but does not directly contact.Have sub-fraction to enter hopper 31 through the feeding-passage 32 of feed supplement mechanism 3 from the material of feeder 2 landing, most of material then directly falls into weighing hopper 41.The material held in the hopper 31 of minitype shaker feeder is used for little feed and accurate feeding.

Consult Fig. 8, described gauging device 4 adopts hopper-type weighing scale, and wherein weighing hopper 41 adopts four symmetrical LOAD CELLS 42 to support, and in order to reduce other mechanism action of system to the impact of measuring accuracy, scale body have employed independently support 43 and supports.

The control setup of granule materials metering device of the present invention adopts Mitsubishi programmable logic controller (PLC) FX3U-128MT, and described control setup and described feeder 2, feed supplement mechanism 3, gauging device 4 pass through to be electrically connected.

Granule materials dosing system of the present invention is applied to the quantitative package of polarized capacitor aluminum case as the part of wrapping machine.

Working process of the present invention is: according to the difference of quantitatively how many different and material, before life's work, first adjust the position of adjustable material-blocking plate 23, then carry out following steps successively:

Step 1, striker plate is retracted, and feeder carries out large discharge feed, and feed supplement mechanism is in micro-state of shaking.

Step 2, after large discharge feed carries out several seconds kinds, estimate through the inventory of striker plate, when this value differs certain value with predetermined value, feeder enters variable-flow feed, and now striker plate has movement.Because package weight is different, this difference is also slightly different; And feed supplement mechanism is still in micro-state of shaking.In variable-flow feeding process, the shift position of striker plate decides according to the real-time detection of flow and the real-time estimation of weight.The detection of flow converts from weigher sense weight, and the estimation of total weight also will comprise the material of the flight between striker plate to weighing hopper.

Step 3, when variable-flow feed reaches certain value, when this value differs certain value with predetermined value, then striker plate stops the landing of material completely, and feeder stops feed.After this, low discharge feed is carried out by feed supplement mechanism.There are low discharge feed and accurate feeding two kinds of modes in feed supplement mechanism.Still the amplitude size of vibration feeder is determined in this process by the real-time detection of flow and the real-time estimation of weight.

Step 4, when low discharge feed reaches certain value, when this value differs certain value with predetermined value, feed supplement mechanism carries out accurate feeding.

Step 5, when accurate feeding reaches predetermined value, feed supplement mechanism stops feed, and whole feeding process terminates.

Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
