Loss-in-Weight Gravimetric Feeder 失重式重量喂料机 Loss-in-Weight Gravimetric Feeder Loss-in-Weight Gravimetric Feeder 失重式重量喂料机（完整版外贸产品文案｜中英对照） 标准名词注释 全称：Loss-in-Weight Gravimetric Feeder 简称：LIW Feeder 行业俗称：失重喂料机、失重秤、连续式重量式喂料机 一、产品概述 Product Overview 中文 失重式重量喂料机是连续闭环计量配料设备。整机料斗搭载高精度称重传感器，通过实时监测料仓内物料重量下降速率，计算实际出料流量，自动调节螺杆转速，持续稳定控制物料输出。 主要用于挤出生产线微量连续添加色母粒、驻极母粒、粉体填充剂、功能助剂。分为单螺杆、双螺杆机型，适配粒子、粉体、玻纤等多种物料。广泛配套无纺布挤出、3D打印耗材挤出、改性造粒、薄膜、管材挤出设备。 English Loss-in-Weight Gravimetric Feeder is continuous closed-loop metering equipment. The hopper is mounted on high-precision load cells. The system calculates actual flow rate by monitoring the weight loss speed of materials. It automatically adjusts screw speed to maintain stable discharge rate. It is widely used for continuous micro-dosing of color masterbatch, electret masterbatch, powder filler and functional additives on extrusion lines. Single-screw and twin-screw types available for pellets, powder, glass fiber and other materials. Perfectly matched with nonwoven extrusion, 3D filament extrusion, plastic compounding, film and pipe extrusion machines. 二、工作原理 Working Principle 中文 1. 称重传感器实时采集料仓总重量； 2. 控制器持续测算单位时间物料减少重量，得到实时出料流量； 3. 对比设定流量，闭环自动调整螺杆转速，修正流量偏差； 4. 物料低位时自动启动上料机补料；补料阶段启用补偿算法，消除加料冲击干扰，保障喂料不间断、精度稳定。 核心特征：连续在线称重、实时动态纠偏。 English 1. Load cells continuously detect the total weight of the hopper. 2. The controller calculates real-time flow rate based on material weight loss per unit time. 3. Compare actual flow with set value, adjust screw speed automatically via closed-loop control to eliminate deviation. 4. Auto refill will be triggered when material level is low. Special compensation algorithm offsets weight impact during refilling, ensuring continuous and stable feeding accuracy. Core feature: Continuous on-line weighing & real-time dynamic correction. 三、核心优势 Key Advantages（中英分行，短视频/画册直接复制） 中文：失重连续计量，喂料精度高，流量稳定可控 English：Loss-in-weight continuous metering, high & stable feeding accuracy 中文：不受物料密度、流动性、架桥现象波动影响 English：Resist fluctuation of material density, fluidity and bridging 中文：单/双螺杆可选，适配塑胶粒子、粉体、短玻纤物料 English：Single / twin screw optional, suitable for pellets, powder and short glass fiber 中文：智能PLC触摸屏，实时流量曲线显示，生产数据可存储导出 English：PLC touch screen, real-time flow curve display, storable & exportable production data 中文：接触物料采用不锈钢材质，拆装便捷，快速换色清理 English：Stainless steel material contact parts, easy disassembly for cleaning & material switch 中文：支持与挤出主机信号联动，同步启停，协同生产 English：Support signal interlock with extruder, synchronous start & stop 中文：可多台并联，实现多种助剂同步连续配比 English：Multiple feeders can work in parallel for simultaneous dosing of various additives 四、适用生产线 Application ✅ 熔喷布、纺粘无纺布挤出（驻极母粒添加） ✅ 3D打印彩虹耗材挤出产线 ✅ PP/PET/PLA薄膜、片材、管材挤出 ✅ 塑料改性造粒、填充改性生产线 ✅ 生物降解材料挤出加工 五、重要区分（业务接待必看，避免和批次称重混料机混淆） 1. Loss-in-Weight Gravimetric Feeder 失重喂料机 ✅ 连续不间断出料；多用于挤出机，微量添加助剂；单通道/双通道为主。 2. Gravimetric Batch Blender 批次称重混料机 ✅ 间歇分批配料；多组分（2/3/4种原料）混合；适合注塑中央供料系统。 六、 中文：失重式重量喂料机 Loss-in-Weight Gravimetric Feeder English：Loss-in-Weight Gravimetric Feeder for Plastic Extrusion 中文：连续闭环失重计量，精准添加色母、功能助剂 English：Closed-loop loss-in-weight dosing for masterbatch & additives 中文：实时流量自动纠偏，稳定挤出制品色差与品质 English：Auto flow correction, stabilize color and quality of extruded products 中文：单双螺杆可选，适配无纺布、耗材、造粒挤出线 English：Single & twin screw design for nonwoven, filament and compounding lines 中文：天天自动化｜挤出配料配套设备厂家 English：Tiantian Automation | Manufacturer of extrusion auxiliary equipment  Loss-in-Weight Gravimetric Feeder | Continuous Weight Loss Feeder for Masterbatch, Powder Additive Dosing on Plastic Extrusion Line
