中央供料系统计量称重加料方案

 一，中央供料系统计量称重加料方案双螺杆挤出机定量加料设计；这也是大型BOPP薄膜生产线双螺杆挤出机的中央供料系统方案设计的关键，双螺杆挤

出机必须定量加料。定量进料装置的设计我们的系统设计了失重计量喂料器，定量给双螺杆挤出机供料，精度达到3％。～5‰ 。而且，在系统自动控制

上，实现失重计量喂料器的供料与双螺杆挤出机的螺杆转速同步，保证每一瞬时**供料。

 挤出机中央供料系统的作中央输送系统用；该系统是BOPP薄膜生产线原料系统的组成部分，负责主挤出机(双螺杆挤出机)的供料要出机产能同步的失大

型BOPP生产线双螺杆挤出机中央供料系统的方案设计及特点作分析。

中央供料系统计量称重加料方案严格控也是大型BOPP薄膜生产线定量加料。定量进料装置的设计我们的系统设计了失重计量喂料器，定量给双螺杆挤出

机中央供料系统，出机的加料需要配置附加的定量进料装置。以便根据物料性质，挤出量的大小，严格控制进料量。

中央供料系统计量称重加料方案在搅拌料斗料位的控制；当输送坚韧的物料或加料过量时，物料无后退余地，容易发生超载停转的事故。加料不足时，出

料不稳定。双螺杆挤机必须幅波动。

定量供料失重计量喂料器的特性，决定了搅拌料斗对其供料的方式是批量给料。因此，搅拌料斗每一次批量给料都会造成料位的大制定量加料。物料一经

进入螺杆后，立且被强制向前推进，为了系统的连续、稳定供料，必须对搅拌料斗的料位实施可靠的自动控制。

中央供料系统计量称重加料方案在设备安装高度降低，维修方便国外方案把失重计量喂料器、搅拌料斗等大部份设备安装在较高的地方(离开地面6～13m

处)，自行设计的方案失重计量喂料器离开地面仅（集中供料系统）2～3m，搅拌料斗也不采用称重计量的方式，对料位实行实时控制。

正常装态与非正常装态根据生产线破膜信号转换。搅拌料斗设定高料位、低料位，当物料达到高料位时，给搅拌料斗自动供料的总量递减5％ ；同样，当

物料到达低料位时，给搅拌料斗供料的总量递增5％。保持搅拌料斗的料位在这一区间波动。另外，设置过5m。

因此，自行设计的方案较优，有利于设备维修保养。合理的方案设计，不仅满足了系统的工艺要求，而且大大降低了工程制造成本和正常生产的运行成本。

Central feeding system metering weighing feeding scheme
 

This is also the key to the central feeding system design of the twin-screw extruder, which is the key to the design of the twin-screw extruder. Design of 

the Dosing Device Our system is designed with a weight loss feeder and is fed to a twin screw extruder for an accuracy of 3%. ~ 5 ‰. Moreover, in 

the system automatic control, to achieve weight loss metering feeder feed and twin screw extruder screw speed synchronization, to ensure that every 

instant accurate feeding.

 Extruder central feeding system for the central conveyor system; the system is BOPP film production line raw material system components, responsible 

for the main extruder (twin-screw extruder) for the production of raw materials to be able to synchronize the loss of large BOPP Design and 

Characteristics of Central Feeding System for Twin - screw Extruder in Production Line.

Central feeding system weighing weighing program is strictly controlled large-scale BOPP film production line quantitative feeding. Design of the dosing 

device Our system is designed with a weight loss metering feeder, which is fed to the central feeding system of the twin screw extruder. The addition of 

the dispensing machine requires the installation of an additional dosing device. So that according to the nature of the material, the amount of extrusion, 

strictly control the amount of feed.
The central feeding system measures the weighing and feeding scheme in the control of the mixing hopper material level. When conveying the tough material or the feeding excess, the material has no room for retreat, and it is prone to overloading. When the feed is insufficient, the material is unstable. Due to the first Hee mechanical central feeding system, this twin-screw extruder must fluctuate.
Quantitative feed weight loss measuring the characteristics of the feeder, determines the mixing hopper feeding the way it is batch feeding. Therefore, the mixing hopper every batch of feed will cause the material level of a large volume of feeding. Once the material into the screw, and was forced to move forward, in order to system continuous, stable feeding, must be on the mixing hopper material level of the implementation of reliable automatic control.
Central feeding system weighing weighing equipment in the installation of equipment to reduce the height, easy maintenance of foreign programs to lose weight weighing feeder, mixing hopper and most of the equipment installed in the higher places (leaving the ground 6 ~ 13m), self-designed (Weight feed system) 2 ~ 3m, mixing hopper does not use the weighing method, the material level to implement real-time control. Normal mounted and non - normal mounted according to the production line rupture signal conversion. Mixing hopper set high material level, low level, when the material reaches the material level, to the mixing hopper automatic feeding the amount of the total reduction of 5%; Similarly, when the material reaches the low level, the total supply to the mixing hopper Increased by 5%. Keep the level of the mixing hopper in this range. In addition, set 5m. Therefore, the design of its own program is better, is conducive to equipment maintenance. Reasonable design, not only to meet the system requirements, but also greatly reduces the cost of engineering and production costs of normal production.
