Examine plate 29, the distribution situation of the resin powder of blanking bin can be observed through Perspex plate 29.The lower end edge of blanking bin
It is circumferentially with the seal groove 34 for installing sealing strip, and sealing strip uses polyurethane, blanking bin and gripper shoe 25 slipper seal
Coordinate, prevent resin powder from spilling.The shape of blanking bin is similar to the shape of the forming hole of mould, and size matches, with
Ensure just can be transported in this mould by the resin powder that it is interior when blanking bin moves.
During concrete use, first, resin powder automatic moulding machine is powered on, mixed resin powder is added
In feeding bin 11, setting the weight of the powder needing compacting on the touchscreen, PLC calculates automatically according to the shape of mould
The height of blanking, is led to charge tube by resin powder by the automatic feeding mechanism in feeding bin simultaneously and is transported in blanking bin 4, blanking
Straight line scraping mechanism in storehouse carries out material and loosens, automatically strikes off the material in blanking bin.When blanking bin height reaches program
When setting requires, feeding bin feed terminates.Subsequently into cold pressure procedure, the touch screen of switch board sets and needs pressure, list
The weight of individual product (resin finish module), after having set, presses automatic button.Under the power of propulsion cylinder, blanking bin moves
To hydraulic press work suppress position, push-down head move down under the effect of lower oil cylinder (driving process is SERVO CONTROL, by under
Push-down head displacement monitored in real time by skid beam mangneto displacement transducer installed above, declines actual range and carries out with setpoint distance
Relatively, by the rotating speed of frequency-changing control system control oil pump, thus reach the height of blanking accurately).In blanking process, in blanking bin
Automatic scraping mechanism material is blown into uniformly in the lower mode cavity of mould.After completing to feed intake, at the anti-work of propulsion cylinder
Under with, blanking bin removes compacting position, now under the effect of hydraulic power unit, is quickly moved by seaming chuck speedup auxiliary cylinder
Move on the mould frame of mould, when close to mould frame, be converted to press slowly, until seaming chuck 5 tightly presses close to mould frame end
Face.By the mating spherical surfaces effect of seaming chuck Yu sphere regulating block, so that seaming chuck is tightly fitted with mould frame end face, protect
Card will not flow material in pressure process.Now, hydraulic power unit carries out pressure dual-side, and upper and lower pressure head is applied to resin simultaneously
On powder, reach the pressure set after compression, thus resin-oatmeal becomes resin sheet of colding pressing, and (after having colded pressing, resin sheet has
Certain intensity).While compacting, feeding bin receives the order of PLC, drives screw feeder bar to blanking at motor 18
Storehouse feed, supplements the weight approximating flake products of colding pressing close to resin to the resin powder of blanking bin, the automatic scraping of blanking bin simultaneously
Material in blanking bin is loosened, strikes off by material mechanism.Then upper cylinder upwards backhaul is to top, and lower oil cylinder is in servo-drive
Under effect, the resin sheet colded pressing is ejected from mould frame that (mould frame surrounding has chamfer bevel, it is ensured that when mould unloading ejects
Resin sheet of colding pressing will not burst apart).Finally, under the effect of cylinder, blanking bin parts are promoted to move forward, by cold for the resin of molding
Tabletting is shifted onto on product holding tray.Then next step circulation is carried out.
Resin powder automatic moulding machine for resin powder product be capable of self-feeding, automatically strike off, automatic cold-press
Process, weight accuracy controls within 3%, meets resin finish module process demand.Special automatic scraping, the setting of Shu Liao mechanism
Meter, not only stability is high, and ensure that the weight accuracy of resin sheet of colding pressing.The connecting device design of feed bin, not only protects up and down
Demonstrate,prove whole material system and sealed intact, simultaneously replacing, convenient disassembly, provide convenient for producing different grain size replacing hopper.
Feeding bin spiral blanking is with comb material and hopper SERVO CONTROL blanking before and after blanking bin, and the sequencing of three coordinates, greatly
The impact of counterweight accuracy of measurement when reducing bulk density difference.Having colded pressing the resin sheet obtained, not only weight accuracy meets work
Skill requirement, and the resin sheet after colding pressing has certain intensity, can deposit, moves, carry, and for Follow-up Industry, automatization carries
For basis.Automatic moulding machine of the present invention improves work efficiency, reduces labor intensity, improve working environment, it is to avoid powder
Dustiness contaminates.
