增重批次式混料机 Gain‑in‑Weight（GIW）Gravimetric Batch Blender

外贸标准名称：Gravimetric Batch Blender，Gain‑in‑Weight Blender（GIW），塑料辅机海外通用叫法，区别于连续失重Loss‑in‑Weight(LIW)机型

产品概述 Product Overview

中文 增重批次式混料机GIW，俗称称重式批次拌料机，依靠增重式称重原理，多组份原料依次投入同一个称重仓完成计量，全部组份称量结束后统一搅拌出料，为批次循环工作模式。 可处理新料、粉碎回料、色母粒、各类颗粒助剂；不受物料密度、颗粒大小、湿度变化干扰，配比稳定。适合注塑、普通吹膜、管材板材挤出、rPET回收改性；支持机台悬挂单机使用，也可集成接入中央供料系统。 对比失重式LIW：GIW为间断批次出料，性价比高；LIW料斗整体称重，实现不间断连续喂料，多用于高速挤出产线。

English Gain‑in‑Weight (GIW) Gravimetric Batch Blender works on batch‑cycle principle. All components are dosed sequentially into one shared weighing chamber. After finishing weighing for every ingredient, all materials are discharged into mixing chamber for homogenization. Handles virgin pellets, regrind, color masterbatch and pellet‑form additives. Batching result is immune to material density, particle size and moisture fluctuation. Widely applied in injection molding, conventional blown‑film, pipe & sheet extrusion, rPET recycling compounding. Can be overhead‑mounted as standalone unit or integrated into central material feeding system. Compare with Loss‑in‑Weight (LIW): GIW works in batch cycles with cost advantage; LIW weighs each hopper individually for non‑stop continuous feeding, preferred for high‑speed extrusion lines.

工作原理 Working Principle

中文

1. HMI调用生产配方，设定每种原料目标重量；
2. 各个原料料斗气动阀门依次打开，物料落入共用称重仓，传感器实时采集重量；
3. 单种原料到达设定重量，料门关闭，切换下一组分投料；
4. 全部组份称量完成之后，称重仓底阀打开，所有物料一起下落到搅拌腔混合；
5. 混合完成整批出料供给主机，随即开启下一轮称重循环。

关键点：先全部称完，再混合出料，只用一套称重传感器完成多组份计量，设备成本优于多传感器失重机型。

English

1. Call production recipe on HMI touch screen and set target weight for each ingredient.
2. Pneumatic gate of each hopper opens sequentially, material falls into shared weighing chamber, load‑cell reads real‑time weight.
3. Gate closes once target weight reached for one component, then switch to next ingredient.
4. Only after all components are fully weighed, bottom valve opens, all materials drop together into mixing chamber.
5. Homogenized batch discharges to processing machine, then next weighing cycle starts.

Key point: Weigh all ingredients first then blend & discharge. Only one set of load‑cell is used for multi‑component dosing, bringing better cost performance versus multi‑sensor loss‑in‑weight units.

优点 Advantages

中文

1. 单套称重传感器实现多组份称量，相比失重式设备投资更低；
2. 配比不受物料密度波动影响，稳定制品色差、克重；
3. 模块化快拆，换料清洗便捷，降低交叉污染；
4. 完整报警逻辑：缺料、配比超差、堵料报警；
5. 可单机机边安装，也可对接中央供料做集中配料站。

English

1. Multi‑component dosing with only one set of load‑cell, lower investment compared with loss‑in‑weight blender.
2. Stable batching regardless of density variation, improve color & part‑weight consistency.
3. Modular quick‑release structure, easy cleaning & material change‑over, reduce cross‑contamination risk.
4. Full alarm functions: material shortage, proportion deviation, blockage.
5. Available for machine‑side standalone installation or integrated into central feeding system as centralized batching station.

缺点 Disadvantages

中文

1. 属于批次循环模式，不适合超高速不间断挤出；高速产线应选LIW失重机型；
2. 需要稳定压缩空气驱动气动料门；
3. 传感器需要定期校准，粉尘、震动会带来称量漂移；
4. 原生设计针对颗粒料，不适合大量超细粉体直接投料。

English

1. Batch‑cycle operation, not ideal for ultra‑high‑speed non‑stop extrusion, choose LIW model for such condition.
2. Require stable compressed air for pneumatic gates.
3. Load‑cell needs regular calibration; dust & vibration may cause weighing drift.
4. Designed for pellets, not suitable for heavy fine‑powder feeding.
