Description

Automatic particle or powder quantative feeder

This invention has been narrated particle quantitative in the hopper or the powder operatorless device of feed repeatedly.

With press or hot press processing granular or dusty material, as grain, the grain powder, medicinal powder or the like must be press, and hot press and other processing machines are placed directly in the bench board top.Can not bench board be placed directly in hopper outlet below.This just needs the bench board lateral arrangement with a certain distance from the place of hopper outlet powder or particulate material to be delivered to bench board from outlet inevitably.Also must make the material quantity of delivering to bench board invariable, to obtain the uniform product of shape and size.

Therefore the purpose of this invention is, a kind of device is provided, and quantitatively transports particle or powder.Automatically coming and going mobile along track under the hopper and between directly over the bench board.

Another object of the present invention is to provide a kind of control mechanism of simple drive motor, so that regulate the cycle of the back and forth movement of autofeed device.

A kind of example of the present invention is the device that once transports a certain amount of powder or particulate material, transports to bench board with a certain distance from hopper by horizontal direction below hopper.It comprises a mechanism that quantitatively transports, and allows back and forth movement between below bench board desired location and the original hopper; A dosing hole mechanism, when quantitatively conveyer moved on to the roundtrip trajectory distal-most end, it came the desired location of bench board, when quantitative conveyer is got back to original position and vertically is squeezed into predetermined shape, under the dosing hole mechanism arrival hopper outlet; Also has a gate mechanism below conveyer, move together with conveyer, when conveyer during to working table movement, dosing hole mechanism closes the bottom, when kinematic mechanism arrives the distal-most end of roundtrip trajectory, gate mechanism withdraws from, and conveyer is waited behind, and the bottom of dosing hole mechanism is opened in the bench board desired location.

At one of this invention more specifically in the example, device has a catch gear, when conveyer moves forward, conveyer and gate mechanism locking; Device has a cam mechanism when conveyer arrives distal-most end, and catch gear is loosened; Device has a gate return mechanism, has only when catch gear loosens, and gate mechanism just can be got back to original position.

Quantitatively conveyer is made up of the mainboard of a predetermined thickness, and mainboard is back and forth driven.Mainboard has the through hole of a predetermined diameter as dosing hole mechanism.A base plate is arranged below the mainboard,, have one to bump pin on the gate, fit on the pit of mainboard, as the catch gear when conveyer moves forward as gate mechanism usefulness.Cam mechanism comprises a fixing cam and a follower, follower and bump pin fit and move forward with base plate.The shape of stationary cam is such, and when base plate arrived the distal-most end of reciprocal track, stationary cam replaced follower, thereby bumps pin and deviate from from the pit of mainboard.

The effect of gate backhaul mechanism is, when the bumping pin and loosen of locking base plate and mainboard, base plate moved backward.The rope of one band counterweight laterally is attached at the rear portion of base plate from an end by a pulley.Counterweight pulls back base plate always.Wind spring or similarly parts also can be used for the plate that undercuts.

And, at suitable position block is arranged all, prevent that base plate and mainboard from withdrawing from backhaul place of reciprocal track, preferably block has damping.

Like this, the autofeed device of this invention just can laterally be transported to bench board to powder that gets off from hopper or particulate material from hopper outlet quantitatively.A certain amount of material is stayed when handling on the bench board, and it, had both made working machine be placed directly on the bench board and also can go material fortune so that process on bench board with regard to the backhaul platform of deactivating.After product treatment on the bench board was over, device was repeatedly delivered to material on the bench board more quantitatively, like this automatically quantitatively to the bench board feed.Above-mentioned purpose of this invention and structure with the explanation of pattern preferably shown in the drawings, will come into plain view.

13,13, and 13 and 13 are contained on the base plate 40.Lower plate 14,14th, brace panel.Opening 15 is arranged on the upper plate 12, corresponding with the outlet 11a below the hopper 11.A pair of

flipper guide

16,16 and 17,17 are arranged, be separately fixed at the both sides, front and back of upper plate 12.Mainboard 18 is between

flipper guide

16,16 and 17,17, and their upper surfaces lean against on the lower surface of upper plate, and can be in the horizontal slip of Fig. 1 and Fig. 2.The lower surface of mainboard 18 works when base plate 23 is closed through hole 19, and through hole 19 is in the front portion of mainboard 18 (by bench board 37 on one side).Base plate 23 is supported from both sides by the back-up roller 24 that is fixed on

flipper guide

16,16 and 17,17.The position of through hole is when mainboard 18 is got back to original position, just in time below the outlet 11a of hopper 11.Can optional position bore one or several through hole 9.Mainboard 18 lower surfaces have a tooth bar 20, and facing to the front side or the rear side of reciprocal track, this tooth bar 20 and miniature gears 22 are chain, and miniature gears 22 is connected with reversing motor 21.Reversing motor 21 is just changeing counter-rotating by switch (not drawing among the figure) as fixed-time controles such as micro-switch, travel switches.One of rope spare is being fixed in the rear end of base plate 23 (in the opposite of bench board one side), and rope spare can be a chain, steel wire, rope etc., and rope hauls base plate 23 by pulley 26 backward by the counterweight 27 that is fixed on the other end.Bump the lower surface that case 29 is fixed on base plate 23, wind spring 31 boundaries are in bumping between case 29 and the spring bracket 30, and spring bracket 30 is fixed on and bumps on the pin 20, upwards heads on and bumps pin, make to bump pin and pass bottom hole 32.Like this, the top of bumping pin 28 is inserted in 33 li of pits on mainboard 18 bottom surfaces, closes the through hole 19 of mainboard 18.Base plate 23 also correspondingly is locked on the mainboard 18.Bump the other end of pin 28 and stretch out from the lower through-hole 29a that

bumps case

29,28a links to each other with follower.Follower 28a links to each other with a stationary cam bar 36, and stationary cam bar 36 is carried out collision, and follower 28a is suspended between

pole

34 and 35, and is laterally parallel with the roundtrip trajectory of mainboard 18.Pole 34 and 35 is fixed on the base plate 40.Stationary cam bar 36 is downward-sloping below bench board 37, when base plate 23 by bumping 18 lockings of pin 28 and mainboard.When arriving the bench board desired location, follower 28a slides from stationary cam bar 28 immediately, makes to bump pin 28 and fall for 33 li from the pit of mainboard 18.

Bench board 37 is at the far-end of pillar 40, and the outside of hopper 11 distal-most end of mainboard 18 roundtrip trajectorys (or), the upper surface of bench board are just in time on the position of the lower surface of base plate 23.The 39th, block.The position that stops when the position of block 39 is mainboard and base plate backhaul on the figure, there is damping the end of block.Fig. 6 and orifice plate 38 shown in Figure 7 are the twice of tooth bar 20 length basically along the distance of the tooth bar 20 of mainboard 18, and can make base plate sliding backward separately on base plate 23, mainboard 18 stayed the far-end of roundtrip trajectory.

In the enforcement pattern of this invention, particle and dusty material 42 are contained in 11 li in hopper.The material 42 of the outlet 11a by hopper 11 and the opening 15 of hopper base 12 is full of the through hole 19 of mainboard 18.As can be seen from Figure 3, mainboard 18 and base plate 23 are all on the original position of roundtrip trajectory, and by bumping pin 28 lockings.Through hole 19 is below hopper outlet 11a, and base plate 23 is keeping off the bottom of through hole 19.In this case, particle or dusty material 42 are full of through hole 19 and are held by base plate 23, and the volume of through hole is by the degree of depth decision of through hole.As shown in Figure 4, (just transferring with electrical motor chain by reversing motor)

miniature gears

22 and 20 engagements of (mainboard 18 back sides) tooth bar drive mainboard and base plate 23 and move to bench board 37 together.When the through hole 19 of mainboard 18 arrives directly over the bench board, bump pin by wind spring 31 to pressing down, when follower 28a slides into stationary cam bar 36 extreme lower positions, bump the pit on the bottom surface that pin is forced out base plate 23.Because base plate 23 is pulled back by counterweight 27 always, base plate is just got back to original position when pin discharges bumping from pit, mainboard 18 is stayed.Open this moment the bottom of through hole 19, and the particle of the inside or dusty material 42a are discharged on the end face 37a of bench board 37.Reversing motor counter-rotating then makes the miniature gears counter-rotating, and by with tooth bar 20 is chain mainboard 18 being brought back to original position.Through hole 32 and pit 33 alignment are bumped pin 28 and upwards shifted 32 li of through holes and pit 33 interlocks onto by the elastic force of wind spring, and are chain mainboard 18 and base plate 23, as shown in Figure 3.

Simultaneously, powder or particulate material 42a do not draw in bench board 32(figure) on working machine put down, press or hot pressing, during to working table movement, the material of handling well is transported to other place at mainboard 18 and base plate 23.The reversing motor 20 of regulating back and forth movement can be by micro-switch, controls such as travel switch.
