Gravimetric Feeder 默认=失重连续喂料机，不是批次混料机 一、产品概述 Product Overview 中文 重量式喂料机（失重式Loss-in-Weight），属于连续式计量设备。依靠料仓重量持续衰减计算出料流量，实时闭环调节螺杆转速，稳定控制物料输出量。 多用于挤出生产线连续微量添加色母、功能助剂、填充料，可单通道/双通道配置，广泛搭配无纺布挤出、改性造粒、薄膜、3D打印耗材挤出产线。 English Loss-in-Weight Gravimetric Feeder is continuous metering equipment. It calculates material flow rate by continuous weight loss of the hopper, and adjusts screw speed via closed-loop control to stabilize output flow. Mainly used for continuous micro-dosing of color masterbatch, functional additives and fillers on extrusion lines. Single or twin screw configuration available. Widely matched with nonwoven extrusion, compounding, film and 3D filament production. 二、工作原理 Working Principle 中文 料斗整体放置称重传感器上；系统持续采集料仓实时重量，计算单位时间物料减少重量得到实际流量； 当实际流量偏离设定值，控制器自动调节螺杆转速，实时修正，保持恒定喂料速率； 料仓低位触发自动补料，补料阶段算法自动补偿，保障整体流量不间断稳定输出。 English The feeding hopper is mounted on load cells. The system continuously monitors real-time weight and calculates actual flow rate by weight loss per unit time. If actual flow deviates from setpoint, the controller automatically adjusts screw speed for constant feeding rate. Low-level sensor triggers auto refilling. Special algorithm compensates during refilling to ensure uninterrupted stable output. 三、核心优势 Key Advantages（中英分行，短视频/画册直接复制） 中文：连续重量闭环计量，喂料精度高，误差稳定可控 English：Continuous gravimetric closed-loop control, high & consistent feeding accuracy 中文：实时流量自动修正，不受物料堆积密度、流动性波动影响 English：Auto flow correction, resist fluctuation of material density & fluidity 中文：单/双螺杆可选，适配粒子、粉体、助剂微量添加 English：Single / twin screw option, suitable for pellets, powder and micro-additives 中文：PLC触摸屏控制，流量参数直观显示，生产数据可追溯 English：PLC touch screen, real-time flow display, traceable production data 中文：接触物料不锈钢，快速拆装，方便清理换料 English：Stainless steel contact parts, easy disassembly for cleaning & material change 中文：直接对接挤出主机信号，同步联动启停 English：Signal interconnection with extruder, synchronized start & stop 四、适用场景 Application ✅ 熔喷/纺粘无纺布挤出（驻极母粒连续添加） ✅ PLA/PET/PP 3D打印耗材挤出生产线 ✅ 塑料改性造粒、填充改性挤出 ✅ 薄膜、片材、管材挤出工艺 ⚠️ 区分：不适合12台注塑中央供料多组分批量配料（该场景优先批次称重混料机Batch Blender） 中文：失重式重量喂料机 Gravimetric Loss-in-Weight Feeder English：Loss-in-Weight Gravimetric Feeder for Extrusion Line 中文：连续闭环重量计量，精准添加色母、功能助剂 English：Continuous gravimetric dosing for masterbatch & functional additives 中文：实时流量自动调节，稳定挤出产品色差与性能 English：Auto flow adjustment, stabilize color and quality of extruded products 中文：适配无纺布、耗材、造粒各类挤出生产线 English：Ideal for nonwoven, 3D filament & plastic compounding lines 中文：天天自动化挤出配料配套设备 English：Supporting equipment for extrusion | Tiantian Automation  Loss-in-Weight Gravimetric Feeder | Continuous Weight Type Feeder for Plastic Extrusion, Masterbatch Dosing  1. Gravimetric Batch Blender 批次称重混料机 多组分、间歇批次混合，适合多台注塑中央供料系统。 2. Loss-in-Weight Gravimetric Feeder 失重式重量喂料机 单/双组分连续喂料，适配挤出机，持续添加助剂。
