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.
The main production: Color Masterbatch, the measurement of color Masterbatch, volume-color Masterbatch, the speed of hot and cold mold temperature, refrigeration equipment, chillers, industrial chillers, screw chillers central feeding system, the central supply accessories , Automatic feeding system, drying equipment, three one machine dehumidification dryer, plastic desiccant dryer, multi-functional temperature machine, high-temperature mold temperature, and other industrial products.
