Technical field
The utility model relates to a kind of macromolecular material processing and forming machinery, and particularly macromolecular material is extruded and used a kind of pellet device in the processing.
Background technology
Pellet device is the important device of macromolecular material extruding pelletization, and generally being divided into has: tie rod bath water cooling and dicing, liquid-ring type are extruded kind such as pelletizing in pelletizing, the air-cooled pelletizing of hot side or the water.Wherein pellet device is the most complicated in the water, but can be connected with large-scale extruder, finishes the per hour pelletizing task of output more than ten tons.Its operation principle is: through the macromolecular material melt of extruder fusion, under the screw rod rotary impetus, constantly be extruded cross-head and enter pelletizing chamber pellet device, that be full of (or convergence is full of) water (or other cooling medium) in the water, and go out the moment that head enters in the water at one and be cut into particle by predetermined grain length degree by grain-cutter.The uniformity of its particle length is one of standard of weighing pellet device quality in the water, and the thermal deformation that influence the inhomogeneity very big factor of particle length be pellet device in the water, cutting knife and head outer panels identity distance from vibration change, cutting knife damaged be out of shape etc.
German patent DE 2328019 discloses pellet device in a kind of water, the pelletizing chamber of this device and cutting knife support member and direct linear connection of drive unit, but can not avoid the influence of thermal deformation to cutting knife and head outside distance.German patent DE 3541500 discloses pellet device in a kind of water, pelletizing chamber in this device directly is not connected with cutting knife support member and drive unit, but be connected with head separately, with avoid thermal expansion owing to the pelletizing chamber cause the thermal deformation of cutting knife support member produce cutting knife and head outer panels identity distance from variation.Yet because the extension of cutting knife support member and drive unit fixture, the volume of this pellet device is bigger, and can not solve problems such as above-mentioned cutting knife and head outside variable in distance fully.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art fully by a kind of simple and practical technical scheme, and pellet device in the outstanding water of a kind of performance simple in structure is provided.
Distinguishing feature of the present utility model is: the pellet device compactness just also can be joined the dexterous motion of wheel carrier with installation in the water that the utility model relates to.Thermal insulation board in the water that the utility model relates in the pellet device can stop cross-head in water or pelletizing chamber heat radiation effectively, avoid head outer panels discharge opening place because the undue heat radiation of water logging face causes discharge opening tip inner macromolecule material melt to ossify or be destroyed, also avoid the hyperthermia thermal deformation or the spacing between them that cause, cutting knife close with it or that paste mutually of head outer panels to change.
Pellet device comprises a pelletizing chamber (8) that has intake-outlet in the water that the utility model relates to; the support (11) of fixed support granulating mechanism and drive motors; it is characterized in that: pelletizing chamber (8) paste connection mutually with thermal insulation board (3) on cross-head outer panels (2) or this outer panels, and support (11) is connected with pelletizing chamber (8) and accompanies or do not press from both sides thermal insulation board (9) between face.Cutter bar in the granulating mechanism (7) direct puncture pelletizing chamber (8), this passes through the place and is sealed by movable sealing device (10).
Cutter bar in the granulating mechanism that the utility model relates to (7) direct puncture pelletizing chamber (8), this passes through the place and is sealed by movable sealing device (10).
The thermal conductivity factor of the thermal insulation board that the utility model relates to (3) and (9) is less than 1/2 of head outer panels (2) thermal conductivity factor, or zirconia Zr
20
3Or Zr0
2Material.Wherein, the thickness of thermal insulation board (3) has the discharge opening (1) with outer panels equal number and big or equal diameter more than or equal to 1 millimeter.
The granulating mechanism that the utility model relates to comprises cutting knife (5), cutting knife fixed body (6), cutter bar (7), bearing (13) and bearing body (12).Accompany an elastomeric pad (14) between the shaft coupling of its cutter bar (7) and drive motors (not shown).
The thermal insulation board that the utility model relates to (3) upward passes through fixedly one deck antifriction metal (AFM) plate (4) of bolt or pressing plate.According to the utility model, thermal insulation board also can not have the antifriction metal (AFM) plate on (3), so that thermal insulation board (3) is directly close with cutting knife (5) or subsides mutually.Wherein, antifriction metal (AFM) plate (4) has the discharge opening (1) with thermal insulation board (3) equal number and big or equal diameter.
