摘要： PURPOSE:To unnecessitate a gear pump, by a method wherein the rotating speed of the second extruder is set to be constant, and the rotating speed of the first extruder is so controlled as to make constant the material pressure difference between the charging side and ejecting side of the second extruder, in a tandem extruder for a molten resin. CONSTITUTION:A die 22 is fitted to a tip part of the second extruder 16 through a filter 21, and a molten resin supplied from a ejecting port of the first extruder 11 through a connecting pipe 23 is extruded. The rotating speed N2 of a screw for the second extruder 16 is controlled to be constant by a loop comprised of a speed detector 19, a speed controller 20 and a driving motor 18. The pressure difference P1-P2 between the charging side and the ejecting side of the second extruder 16 is detected by pressure difference detectors 24, 25 and a comparing calculator 26, and a pressure controller 28 performs a cascading action on a screw rotating speed controlling system for the first extruder 11 which system is comprised of a speed detector 14, a controller 15 and a driving motor 13 so that the pressure difference becomes a set point 27, whereby the pressure difference P1-P2 is controlled to be constant. Accordingly, clogging of the filter can be automatically compensated for without using any gear pump.

摘要： PURPOSE:To improve the kneading and mixing effects of thermoplastic resin by a method wherein left and right roots are formed so as to be changed in the same phase but the central root is formed so as to be changed in the reverse phase in case the depth of the root is changed from A to B while at least two pieces of A and B sections of the root are provided within one pitch of the screw. CONSTITUTION:Two places of the most shallow section and the most deep section are existing within one pitch of first flight 11 and the phases of the root sections 15, 16 are reversed. pellets within one pitch of the first flight 11 receive strong compression force as well as sure kneading effect by the wedge effect of the root sections and a cylinder 6 when the depths of the roots 15, 16 are changed from A to B (twice during one pitch) or the depth of the root 14 is changed from B to A (twice during one pitch). The kneaded and molten resin is sent forcibly over a clearance C at the tops of second flight 12 and third flight 13 and flows from the shallow side A to the deep side B whereby the resin in the roots 14, 15, 16 may be kneaded well.

摘要： PURPOSE:To contrive to improve the surface replacement effect and to prevent venting-up from occurring by a structure wherein 2-6 flutes, each of which consists of two threads respectively having specified angles in the axial direction and one group of each of which is a flute open on upstream side and closed on downstream side and the other group of each of which is a flute open on downstream side and closed on upstream side, are provided in such a manner that said two groups of flutes are arranged alternately. CONSTITUTION:Flutes 14, each of which is open on upstream side and closed on downstream side, and flutes 15, each of which is open on downstream side and closed on upstream side, are alternately arranged with no communication between the flutes on the outer peripheral surface of a screw element 13 provided just before the vent port 12 of a screw main body 11. Resin entered the flute 14 from the main body 11 side passes over a thread 16 through a small gap (b) into the flute 15. The angle alpha between the thread 16 and the axis of the main body is set at 25-45 deg., because resin is sent in the flute 14 at all times. Further, because the depth of the flute 15 is made larger than that of the flute 14 or the volume in the flute 15 is larger than that in the flute 14, the resin entered the flute 15 is released from its compressed state, resulting in increasing volumetrically and consequently improving the surface replacement effect. The angle beta between the thread 17 and the axis of the main body is set at 50-75 deg., because the flute 15 itself must have resin conveying capacity. The number of flute is made to be 2-6.
摘要翻译：目的：为了改进表面更换效果，并防止由2-6个凹槽（其中每个由两个螺纹分别在轴向方向上具有特定角度）和一组每个螺纹组成的结构发生排气在上游侧开放并且在下游侧封闭的槽纹，其另一组是在下游侧开放并在上游侧封闭的沟槽，以使所述两组沟槽交替布置的方式设置。构成：在上游侧开放并在下游侧封闭的槽14，在下游侧开放并在上游侧封闭的槽纹15交替配置，在外周侧的槽纹之间不连通设置在螺杆主体11的通气口12正前方的螺纹元件13的表面。从主体11侧进入凹槽14的树脂通过小螺纹16穿过槽16中的小间隙（b）螺纹16和主体轴线之间的α被设定在25-45度，因为树脂始终在凹槽14中被传送。此外，由于凹槽15的深度大于凹槽14的深度或凹槽15中的体积大于凹槽14中的体积，所以进入凹槽15的树脂从其压缩状态释放，导致增加体积大，从而改善表面替换效果。螺纹17与主体轴线之间的角度β设定在50-75度，因为槽15本身必须具有树脂输送能力。长笛的数量为2-6。

CONSTITUTION:Discharge pressure of a melter 11 is detected by a pressure detector 16 feedback of which is applied to a pressure adjusting device 17, through which the discharge pressure is controlled by adjusting a speed of an electric motor A13 through control part A12 of the electric motor. A rotor 18 which is downstream a filter A15 is driven by an electric motor B20 whose speed is adjusted by a control part B19, and molten resin to be supplied from the filter A15 is quantified at every cog of a gear. The stable quantitative molten resin is supplied to a homogenizer 22 on an outlet side of the rotor 18 from the rotor 18, through which a temperature of the resin is lowered to a target temperature and at the same time the titled device possesses a screw equalizing the temperature of the resin. The screw is driven by an electric motor and generates pressure necessary for the resin to pass through a filter B23 and a die 24 located downstream of the screw.

摘要： PURPOSE:To efficiently perform kneading and mixing, by forming three troughs helically around a shank so that a wider trough may be formed between the right trough and the left trough, while the cross sections of the shank may be eccentric, the phases of the troughs are reversed, and the sum of the cross sectional areas of the right and left troughs may be about equal to the cross sectional area of the intermediate trough. CONSTITUTION:Troughs 35, 36, 37 form eccentric circles around the axis of the screw 31 and the phase of the trough 35 is reversed to the phase of the troughs 36, 37. Thus pellets existing in one pitch of the first flight fed through the troughs having different depths will be subjected to a strong pressure due to the wedging effect between the troughs and the cylinder inner surface thereby being kneaded, and the kneaded and melted resin is forced to proceed over the second and third flights to the next trough and is mixed. As the sum of the cross sectional area of the right and left troughs is about equal to the cross sectional area of the intermediate trough, the kneaded and melted resin can be fed over the first and second flights smoothly and can be mixed.
