Description
Technical field
The present invention relates to the vacuum forming device on a kind of industrial equipment, particularly relating to a kind of is the vacuum machine spreading machine of the production medium density fibre board (MDF) of raw material with wood fibre.
Technical background
From the developing history of medium density fibre board (MDF), fiberizing equipment spreading machine is broadly divided into three classes according to the spreading head forming principle.The one, mechanical spreading machine, the 2nd, vacuum pneumatic spreading machine, the 3rd, orienting spreading machine.Because of orienting spreading needs HV generator, control and maintenance requirement are higher, seldom use in medium density fibre board (MDF) is produced at present.Other are several because of its characteristics are respectively arranged, and all are used widely so far.
Be illustrated in figure 1 as most typical German Siempelkamp fibre machinery spreading machine, mainly by feed arrangement 01, gantry pillars 02, charging swing mechanism 03, feed bin feeder 04, claw device 05, feed bin 06, throw roller arrangement 07, feed bin conveyer belt 08, spreading head 09, underframe 010, slab and put down device 011 etc. and form.This fibre machinery spreading machine is that the fiber after will measuring by the mechanism of various disc rollers, porcupine roller is loose, free settling under the effect of fiber gravity and form slab.Specifically fiber is delivered to feed bin feeder 04 continuously by feed arrangement 01, under 03 effect of charging swing mechanism, the swing of charging limit, limit, make fiber along laterally evenly being sprinkled into feed bin 06 and being deposited on the feed bin conveyer belt 08, claw device 05 in the feed bin 06 is vertically harrowed into uniform accumulation with piling up the fiber that gets up along feed bin 06, and fills up feed bin 06 gradually.Feed bin conveyer belt 08 at the uniform velocity moves forward, and material is delivered to the material mouth, forces throwing to be loose by throwing roller arrangement 07, and the fiber of even and continuous equivalent is provided to spreading head 09.Fiber drops down onto equably on the belt conveyor of forming line, and forms certain thickness slab under the effect of 09 1 groups of flat throwing porcupine rollers of spreading head.Slab is sent to forming room, puts down under device 011 effect at slab, and it is even to form thickness at last, the slab of surfacing.
The slab of this machinery spreading machine moulding is more fluffy, intensity is low, and slab is difficult to rapid transit, and fiber only depends on the self gravitation sinking speed slow, and shaping speed is low, and production efficiency is not high; The slab density of mating formation after the moulding is little, when precompressed and hot pressing, get rid of a large amount of air, therefore, can take away many fiber fines, causes wastage of material.If control is bad during hot pressing, can occur blowing the limit phenomenon, influence the production board quality.But the slab density of mechanical spreading machine moulding is even, and device structure is simple, and energy consumption is little, and operation, adjustment and maintenance are all very convenient.The machinery mode of mating formation is more suitable for thin plate production.
