Definitions

  • a mixing tool for use with a machine for mixing glue with particulate material such as shavings in which the machine has a drum shaped container in a shaft rotatable on the axis of the container.
  • the mixing of the glue with the particulate material is effected by tools extending radially from the shaft and each consisting of a body cylindrical at the radially inner end adjacent the shaft and a head at the radially outer end of the body.
  • the head has a forwardly protruding nose and the head and body taper inwardly to the juncture thereof when viewed in the circumferential direction.
  • Each tool is tubular and a coolant pipe extends radially outwardly inside each tool and supplies coolant fluid thereto.
  • Each tool preferably has a blade-like element thereon near the radially outer end that is inclined to exert a radially outward force on work material in the drum shaped container of the machine.
  • the present invention relates to a mixing tool for machines for applying glue to shavings, fibers or similar mixing material of wood, bagasse or the like, especially cellulose containing materials. More specifically, the present invention relates to a mixing tool of the above mentioned type which is connected to a mixer shaft arranged centrally in a drum-shaped mixing chamber and which with its head portion rotates at a high speed in the vicinity of the wall of the mixing chamber and immerses into the material to be mixed.
  • Mixing tools of this type are customarily designed in the manner of a paddle, the narrow side of which is aligned approximately parallel to the axis of rotation of the mixing tool and for obtaining an axial transport of the material to be mixed is slightly inclined with regard to its axis of rotation.
  • the shavings are supposed to be rubbed against each other at a certain pressure so that the glue will be uniformly wiped over the surfaces of the shavings.
  • the pressure must not become too high because otherwise the shavings will be broken down excessively, and the strength values as well as the quality of the eventually obtained plate will be reduced.
  • this low friction will not suffice to distribute the glue over the surfaces of the shavings.
  • the tools in the discharge zone are intended to increase the pressure of the shaving ring onto the drum wall which pressure is brought about by centrifugal forces, so that a flap which is held closed due to a preload will open in order to permit the material to be freely discharge. Due to the shape and the angle of attack of the customary paddle-shaped tools, however, an excessive pressure is built up radially outside the head range and in the short running ahead range encountered in the direction of rotation da so that the flap will very suddenly open up and will then as suddenly and strongly close. Thus, the withdrawal flap carries out strongly pulsating opening and closingmovements which permit no uniformly flowing discharge of the product.
  • An adaptation of the emptying or discharging quantity to the thickness of the respective product ring obtained in the mixing chamber can be effected only by mechanically adjusting the angle of attack of the paddle-shaped mixing tool relative to the axis of rotation when the machine is at a standstill.
  • an object of the present invention to provide a mixing tool which treats very carefully the shavings and the machine parts and which simultaneously when employing a mixing zone brings about a uniform application of glue to the shavings and, when employed in the discharge range, brings about discharge quantities depending on the filling and also brings about a dampened pulsating discharge.
  • FIG. 1 shows a section through a mixing tool according to the invention, said section being taken along the line l-l of FIG. 5.
  • FIG. 2 shows a section through the mixing tool of the invention, said section being taken along the line ll-ll of FIG. 5.
  • FIG. 3 illustrates a section through the mixing tool according to the invention, said section being taken along the line lll-Ill of FIG. 5.
  • FIG. 4 shows a section through the mixing tool of the invention, said section being taken along the line lV-lV of FIG. 5.
  • FIG. 5 represents a section through the mixing tool
  • said section being taken along a plane perpendicular to the axis of rotation of the mixing tool.
  • HO. 6 is an axis normal section through a mixing chamber where two mixing tools, according to the invention, are located opposite to each other on the mixer shaft.
  • a mixing tool according to the present invention is characterized primarily in that the head range, when viewed in the direction of rotation of the body of the mixing tool is divided by a narrow section which while forming surfaces inclined toward the interior of the mixing chamber and the mixing chamber wall gradually widens towards the head range and toward the body.
  • the mixing tool according to the invention is furthermore characterized in that the cross sectional dimensions on the mixing tool when viewed in a direction perpendicularto the direction of rotation at least to no material extent drop below the maximum cross sectional dimension when viewed in the direction of rotation.
  • the shavings are for purposes of the distribution of glue divided in the direction of the radials toward the mixing chamber, and the surfaces of the body of the mixing tool which are inclined toward the mixing chamber wall are with a rather high filling of the mixing chamber exerting a pressure in the ring of the mixing material in the direction toward the mixing chamber wall and thereby upon the discharging or emptying flap so that with a rather high filling of the mixing chamber, an accelerated emptying is effected so that a tendency for forming a uniform and optimum strong ring of mixing material will be generated.
  • the head range has its greatest width in the direct vicinity of the mixing chamber wall, the generation of a dead zone of pressed and only slowly moving mixing material in the vicinity of the wall is avoided because the here present shavings are grasped by the inclined lateral surfaces of the head range and are moved toward the center of the ring of shaving material.
  • This effect is advantageously aided by the fact that the head range has a front nose when looking in the direction of rotation, which grasps the shaving material near the wall and deviates the same addi tionally toward the center.
  • the body of the mixing tool is, in its radial inner range, designed as a tube of round cross section which is provided with a thread and may thus be connected by screws to the mixer shaft.
  • the maximum width of head range advantageously amounts to about 0.5 l.5 times, preferably, however, to 0.6 times the outer diameter of the round tube.
  • cooling liquid is passed through a hollow mixer shaft by means of a feeding pipe arranged in the interior of the tool and is conveyed to a radially outer range of the mixing tool and is discharged in a gap between the feeding tube and the inner wall of the tool. From a cooling technical angle, the tool mantle has a particularly favorable uniform wall thickness.
  • a suitable impact surface is arranged in the extension of thefeeding tube for the cooling liquid in the rear head range of the tool (with regard to the direction of rotation of the tool).
  • This impact surface deviates the impacting cooling liquid in the direction toward the interior of the nose.
  • a-portion of the inner surface of the tool mantle acts as impact surface, which tool mantle in its outer contour, as viewed in the direction perpenducular to the direction of rotation has a slanted end.
  • the tool at least in the radial outer range of the impact surface which when viewed in the direction of rotation has a lateral outer confinement of the head range, tearing off edges inclined to the relative movement of the mixing material occur in the rear head range (when viewed in the direction of rotation), which tearing off edges will cause an additional whirling or agitation of the shavings.
  • the embodiment illustrated therein comprises a body 10 with a head section 11. Between the body 10 and the head section 11, when viewing in the direction of rotation indicated by the arrows 12, there is provided a constric tion 13. From this constriction 13 in the direction of the head section 11 toward the interior of the mixing chamber there extend inclined lateral surfaces 14 whereas toward the outer mixing wall 15 there extend inclined lateral surfaces 16.
  • the body 10 is within its radial inner range designed as a round pipe 17 which has an outer thread 18 for connection to a mixer shaft 19. This screw connection is secured by a counter nut 20 (HO. 6).
  • the round pipe 17 is within the region of the inclined lateral walls 16 flattened on both sides so that an approximately elliptical shape is obtained.
  • the head section (see FIG. 2) has starting from the constriction 13 approximately the shape of a shoe with a nose extending forwardly in the direction of rotation.
  • Cooling fluid is conveyed through an inner pipe 22 of the hollow mixer shaft 19. This cooling fluid passes from the mixer shaft 19 due to a pumping or centrifugal effect into a feeding pipe 23 which extends up to and into a radial outer range of each mixing tool.
  • the cooling fluid which flows in the direction of the arrows 24 in FIG. 5 will, when leaving the feeding pipe 23, along an extension thereof impart upon an impact surface 25 which is designed as a portion of the mantle of the mixing tool and which impact surface is arranged in the rear head section 11 and is inclined in such a way that the impacting fluid is in the direction of the arrows 24 sprayed into the interior of the nose 21 in order intensively to cool the nose 2! which runs ahead and is subjected to the greatest thermal stresses.
  • the cooling fluid is discharged through the space between the mantle of the mixing tool and the feeding pipe 23 and is conveyed in the annular space 26 toward the mixer shaft.
  • an emptying or discharging flap 27 which, when the machine is at a standstill, is kept closed by a preload, for instance a counter weight 28.
  • a preload for instance a counter weight 28.
  • the head section 11 together with the nose 21 loosens up the ring formed by the mixing material and lifts the ring off the drum wall and throws it on both sides uniformly toward the side.
  • the mixing tool does not exert a direct pressure upon the drum wall so that the shavingswill not be pressed and damaged but will rather be intermixed with the material therebelow and radially further toward the interior.
  • the inclined side surfaces 16 of the body move in the material to be mixed and in contrast to the side surfaces 14 of the head section 11 exert upon the material to be mixed a pressure in the direction toward the wall of themixing chamber. This pressure increases with the thickness of the ring of the material to be mixed and with the degree of filling of the machine because the surface which is located within the material to be mixed and pushes laterally toward the wall 15 of the mixing drum likewise increases.
  • the pressure exerted by the mixing material upon the walls of the mixing chamber and thereby upon the discharge flap 27 will slightly drop in the direct head section ll of the mixing tool because the lateral surfaces 30 and 31 of the nose will push the material in the direction toward the center of the mixing chamber.
  • the tool passing by the discharge flap 27 is followed by the soft pressure of the shavings which with a corresponding filling height is in particular by the lateral surfaces 16 of the body 10 6 pressed toward the outside,-which pressure permits a highly dampened pulsating withdrawal of the mixing material.
  • the throughput quantities may vary, for instance, from between 2 to 6 tons per hour.
  • the thickness of the ring of the mixing material in the glue applying machine must, however, remain substantially constant so that the higher throughput has to be realized by causing the shavings to pass through the machine at a higher rate of speed.
  • the design of the tool according to the present invention will in the manner described above assure that with all throughputs a ring of shavings will be obtained which has substantially the same thickness. In practical operation, particularly at higher throughputs, disorders are sometimes encountered which cause a rapid increase in the filling of the glue applying machine. This results in a faulty gluing in view of too little movement of the shavings. The machine will then clog up and the drive will be choked off.
  • the tools arranged in the discharge elements are provided with conveying elements 35 which in response to the intended maximum thickness of the ring of shavings being exceeded will immerse into the mixing material and by means of the working surfaces 36 adjusted toward the wall 15 of the mixing chamber will exert an additional pressure in outward direction upon the shavings.
  • the ring of shavings becomes thicker than the radial distance between the inner wall of the drum and the outer margin of the conveying elements, the latter will exert upon the excessive thickness of the ring of shavings stronger conveying impulses in the direction toward the discharge. An increasing overfilling is thus counteracted automatically.
  • the intensive cooling of the tool greatly contributes to the fact that no disorders in the glue applying process will occur due to the formation of lumps in the mixing zone and that also no disorders will occur in the discharge operation.
  • the tool according to the present invention has great advantages over paddle-shaped tools because the last mentioned tools will not permit any favorable structural design of the hollow chamber for receiving the necessary cooling means.
  • Such hollow chamber design brings about that the paddle-shaped mixing tool would become too great in width and thickness while on the other hand a controlled guiding of the cooling medium to the outer head section which is most subjected to frictional heat will hardly be possible.
  • the formation of deposits on the poorly or not at all cooled surfaces of the mixing tool are inevitable.
  • the present invention creates a tool which in addition to having a highly satisfactory mixing effect reduces the wear of the machine and the tool to a minimum, permits an optimum cooling in spite of a simple construction and at the same time exerts a substantially uniform dampened pulsating pressure upon the discharge flap 27 and discharges a quantity of mixing material which corresponds to the respective degree of filling.
  • a mixing tool according to claim 1 in which said head when viewed at right angles to the direction of rotation has the greatest dimension adjacent the container wall and when viewed in the direction of said axis has a forwardly protruding nose.
  • a mixing tool according to claim 1 in which the radially inner end of said body is circular in transverse cross section and has a thread formed thereon for connection of the body to the shaft.
  • a mixing tool in which said body is circular in cross section at the radially inner end and the width of said tool at the juncture of said head and body when viewed in the circumferentialdirection is about one-third of the length of the tapered region of said body, the greatest width of said head when viewed in the circumferential direction amounting to from about one-half up to about equal to the diameter of the radially inner end of said body.
  • a mixing tool in which said head has a forwardly protruding nose formed thereon terminating in a rounded tip, said head comprising plow-shaped surfaces extending rearwardly from said tip on the radially inner sideof said nose.
  • a mixing tool in which said tool is tubular and has substantially uniform wall thickness, and a coolant pipe extending radially inside said tool for supplying coolant to the inside thereof near said head.
  • a mixing tool in which said head has a forwardly protruding hollow nose portion and on the inside has a surface disposed in front of the discharge end of said coolant pipe and inclined to direct coolant fluid from the pipe toward the forward part of said nose portion.
  • a mixing tool which includes a conveying element mounted on the tool in a radial region thereof near the radially inner limit of work material in the container, said element having a surface inclined toward the peripheral wall of the container and operable during rotation of the tool to develop a radially outward pressure on the work material.
  • a mixing tool according to claim 1 which includes at least two said tools mounted on said shaft in uniformly circumferentially distributed relation.
  • a mixing tool according to claim 9 in which the container is circular in cross section and said tools are threadedly connected to the shaft for radial adjustability thereon.
