摘要： A water flow guide stationarily mounted in the water box of an underwater pelletizer to selectively direct the pressurized water flowing through the water box in order to more efficiently cool and rigidify the extruded polymer strands and enable the rotary cutter blades to more effectively shear the strands into pellets and to convey the sheared pellets away from the die face and rotary cutter blades of the pelletizer to the water box outlet. The water flow guide provides an accurately guided pressurized water flow which enables pelletization of polymers of various diameters and a wide range of specific gravity and rheological characteristics.

摘要： An insulation plug is disclosed for mounting in and generally filling a central recess in the die face of an extrusion die in an underwater pelletizer. The insulation plug is in the form of a rigid circular plate that substantially fills the recess in the die face oriented in opposed relation to a cutter hub and cutter knives of the underwater pelletizer and is secured in place by a fastening bolt. The insulation plug may be made of solid one piece construction or hollow two piece construction, but is made of a material having low heat conductivity. The plug has raised and recessed portions to form bottom and side air gaps within the recess. The plug reduces the transfer of heat from the molten polymer being extruded through orifices in the die plate to water circulating through a water box of the underwater pelletizer. A rigid bushing or spacer may be used in existing extrusion die plates to maintain the bottom air gap against compressive forces generated by the fastening bolt when attaching the circular plate.

摘要翻译： 公开了一种用于在水下造粒机中安装并大体上填充挤压模具的模具面中的中心凹部的绝缘塞。 绝缘插头是刚性圆形板的形式，其基本上填充了模具表面中的凹槽，该模具面相对于切割轮毂和水下造粒机的切割刀相对地定位，并通过紧固螺栓固定就位。 绝缘插头可以由实心的单件结构或中空的两件式结构制成，而是由具有低导热性的材料制成。 插头具有凸起和凹入部分，以在凹部内形成底部和侧部气隙。 塞子减少了从熔融聚合物中挤出的热量转移到模板中的孔口，通过水下造粒机的水箱循环的水。 可以在现有的挤压模板中使用刚性衬套或间隔件，以在安装圆板时保持底部气隙抵抗紧固螺栓产生的压缩力。

摘要： A pelletizing die includes a pelletizing die member with a die exit side exposed to cooling fluid and a die entry side for receiving polymer fed thereto. The die member has a plurality of polymer channels and a plurality of extrusion orifices connected to a respective one of the channels to form a extrusion orifice section. A heating medium system has additional heating medium conduits between channels and a supply and intermediate header for heating the channels (radially from each side) and providing once in and once out heating medium flow. The die member may be formed by high temperature brazing of components using coordinated solder (Ni based or gold-nickel) and component heat treatment temperature. A thin hard face coating may be provided on raised extrusion orifice ring faces around each extrusion orifice section.

摘要： An underwater pelletizer cutting system allowing fine adjustments of the relative spacial relationship between an extrusion die and the blades of a cutting assembly. The cutting assembly, which may be self-aligning in nature, is borne on the end of a drive shaft driven by a motor mounted on a carriage. The carriage is moveable relative a fixed frame by a servomotor driving a ball screw. The ball screw, which preferably has zero backlash, has a shaft attached at one end to the carriage for moving the carriage. A PLC control system may be provided to accept inputs from an operator and to run a cutting program, providing appropriate signals to the servomotor to advance the cutting assembly as needed as the blades of the cutting assembly wear. The PLC system may receive signals from a measuring system adapted to measure the contact pressure between the cutting assembly and the face of the extrusion die.

The method comprises introducing an ethylene-vinyl alcohol copolymer solution containing at least 50 parts by weight of an alcohol having a boiling point of not higher than 100null C., relative to 100 parts by weight of the ethylene-vinyl alcohol copolymer therein, into an apparatus, and contacting it with water in the apparatus, thereby letting the alcohol along with water out of the apparatus and taking the resulting aqueous ethylene-vinyl alcohol copolymer composition that contains from 0 to 10 parts by weight of the alcohol and from 10 to 1000 parts by weight of water, relative to 100 parts by weight of the ethylene-vinyl alcohol copolymer therein, (step 1), and a step of feeding the aqueous ethylene-vinyl alcohol copolymer composition into an extruder, kneading it in melt therein, and then extruding the copolymer out of the extruder (step 2). Also provided is a method for producing pellets of the ethylene-vinyl alcohol copolymer resin, of which the advantages are that the method enables stable production and rapid washing of the pellets and that the pellets produced can enjoy stable extrusion and thermal stability in long-run extrusion working lines. The method comprises cutting the ethylene-vinyl alcohol copolymer resin extruded out of the extruder in the step 2 in the resin production method.
