Description

A kind of dress of living beings recombinant material press device send pin mechanism
Technical field:
The present invention relates to living beings recombinant material press device, the dress that relates generally to living beings recombinant material press device send pin mechanism.
Background technology:
Existing bamboo material is pressed into Recombined bamboo square stock section bar, the general vertical press that adopts, because bamboo material is broken into hardness after strand, deflection is good, so, in the time being loaded on the material of charger charging box and being entered press die cavity by pushing tow, can not produce the packing phenomenon of material, can ensure the integrated square stock even density that suppresses, quality is good.The lockset of vertical press is to stand up upward at press die cavity internal orifice, wear pin mechanism and be located at frame one side, by a row of horizontal setting wear pin cylinder by the heading in lockset pin-and-hole suitable for reading of locked mode pin level, visible, the pin mechanism of wearing of vertical press very easily arranges and realizes.
But in the time adopting fast-growing wood raw material compacting Scrimber square stock section bar, need first fast-growing wood be peeled into very thin veneer sheet material or dredge into wood wool, because of veneer sheet material with wood wool quality is soft, hardness deflection is poor, if also material pushing tow is entered by charger to the vertical die cavity of press as bamboo wood, very easily produce the packing phenomenon of material, easily make the square stock section bar density unevenness after compacting, intensity is bad, off quality.So, compacting fast-growing wood reconstituted material should adopt horizontal press, and the die cavity of horizontal press is accumbency, die cavity is put in lockset accumbency, and now vertical direction is worn locked mode pin up and down, but, above press die cavity, be not easy to again arrange all wear pin mechanism, can only vertically arrange wear pin mechanism wear pin cylinder, and be not easy to arrange other mechanisms such as horizontal storage pin box, so just limited the application that adopts horizontal press compacting fast-growing living beings recombinant materials.
Summary of the invention:
The present invention's object, be to solve horizontal press and be not easy to arrange a difficult problem of wearing pin mechanism, provide a kind of dress of living beings recombinant material press device to send pin mechanism, it is as the auxiliary equipment of horizontal press, the pin mechanism of wearing that aims at horizontal press provides dress pin and send pin, then has implemented to wear locked mode pin by the ejector pin cylinder that press is worn pin mechanism.
For reaching the technical scheme that foregoing invention object takes be, a kind of dress of living beings recombinant material press device send pin mechanism, comprise ejector pin device 1, be connected mutually with ejector pin device end turn over pin assembly 14, with turn over the corresponding setting in pin assembly below send pin assembly 25.
Described ejector pin device 1, by base plate 2, be fixed on to hold under a corresponding vertical storage pin box 12 before the branched ejector pin bar 5 of the affixed row of the ejector pin cylinder 3 of base plate one end, the removable top board 4 with ejector pin cylinder plunger connection on base plate 2, removable top board front end, every support top pin rod, storage pin box another side and have the lock-joint of going out 11 and form.Horizontal two ends of described removable top board 4 are provided with ejector pin balance travel mechanism, it comprise the guiding trestle 7 that is fixed on base plate ', guiding tooth bar 7, gear 8, the balance shifting axle being loaded on balance shifting axle 9 that be meshed with guiding tooth bar installed on guiding trestle be loaded on the base 10 fixing with removable top board 4 by bearing
The described pin assembly 14 that turns over, by the frame plate 15, the warp beam that are fixed on base plate 2 end two sides take up minor axis 17 on frame plate, in two lateral frame plates with two minor axises fix can 90 ° upset swing turn over pin-and-hole plate 18, turn over pin-and-hole plate and have that a row turns over pin through hole 19, two side minor axises are equipped with respectively upset oscillating cylinder 16 in frame plate outside and form.Turn over pin-and-hole plate bottom surface and there is the first pin control device that falls,
Described send pin assembly 25 with its on turn over pin assembly and arrange in the same way, by the rectangular outside framework 26 of section, outside framework end face have an exclusive framework pin-and-hole 26 corresponding with turning over pin-and-hole plate 18 on it ', be located at being pulled in outside framework and mobile send pin cage 27, send pin cage one side to be provided with to send pin-and-hole plate 31, send pin-and-hole plate to there is a row and outside framework pin-and-hole 26 ' corresponding pin through hole 32 that send to form.Send pin cage upper and lower side to be provided with roller 29, outside framework one end is fixed with motor 28, walk around chain 30 its one end of motor output gear and send pin cage one end to fix, its other end walk around the first sprocket wheel 29 ' and the second sprocket wheel 37 of being loaded on hydraulic press opposite side with send the pin cage other end to fix, send pin-and-hole plate bottom surface to there is the second pin control device that falls.
The beneficial effect that the present invention produces:
The present invention by ejector pin device, turn over pin assembly, send pin assembly three parts to form, as the auxiliary equipment of horizontal press, aiming at the pin mechanism of wearing of being located at horizontal press die cavity lockset top provides dress pin and send pin, implemented to wear locked mode pin for lockset by press ejector pin cylinder again, make horizontal press compacting fast-growing living beings recombination sectional material become possibility, effect is good.
