# 注塑瓶坯模具除露机 · 工作原理（中英双语 · 正式专业版） # Working Principle of PET Preform Mold Dehumidifier --- ## 1. 概述（原理总述） ### 中文 本设备专为解决**PET瓶坯低温模具因环境温湿度差产生的结露问题**而设计。 通过**深度除湿 + 恒温加热 + 同步吹扫 + 气帘阻隔**，将车间空气处理为**超低露点干燥热风**，在开模瞬间对模具进行干燥，从根源消除凝露，保证瓶坯质量与连续生产。 ### English This equipment is designed to solve **condensation on low-temperature PET preform molds caused by temperature and humidity difference**. Through **deep dehumidification + constant temperature heating + synchronous blowing + air curtain isolation**, it processes ambient air into **ultra-low dew point dry hot air** to dry the mold at the moment of mold opening, fundamentally eliminating condensation and ensuring preform quality and continuous production. --- ## 2. 详细工作原理 ### （1）空气净化过滤 ### 中文 环境空气由风机吸入，经过**初效、中效、高效三级过滤**，去除粉尘、毛絮及杂质，防止喷嘴堵塞与除湿部件损坏。 ### English Ambient air is drawn in by the main fan and filtered through a **3-stage filtration system (G4+F8+H13)** to remove dust, lint and impurities, preventing nozzle blockage and damage to dehumidification components. --- ### （2）深度除湿（核心原理） ### 中文 洁净空气进入**蜂巢转轮/分子筛除湿系统**，转轮内部微孔结构吸附空气中的水分，将空气处理至**露点 ≤ -40℃** 的超干燥状态，从源头去除湿气。 ### English Clean air enters the **honeycomb rotor / molecular sieve dehumidification system**. The microporous structure inside the rotor absorbs moisture in the air, processing the air into an ultra-dry state with **dew point ≤ -40℃**, removing moisture at the source. --- ### （3）恒温加热控制 ### 中文 干燥空气经**恒温加热装置**加热至 **40～60℃**，温度**可控。 热风略高于模具温度，既不影响模具冷却与生产周期，又可避免二次结露。 ### English Dry air is heated to **40~60℃** by a **constant temperature heating device** with precise temperature control. The hot air is slightly higher than mold temperature, which neither affects mold cooling & cycle time nor causes secondary condensation. --- ### （4）均匀分流输送 ### 中文 干燥热风通过**多通道分流系统**，均匀分配至模具**型腔、分型面、顶针区域**，保证多腔模具每一个位置风量一致，无干燥死角。 ### English Dry hot air is evenly distributed to the **cavity, parting surface and ejector pin area** of the mold through a **multi-channel air distribution system**, ensuring uniform air volume at every position of multi-cavity molds without dry dead zones. --- ### （5）开模同步吹扫 ### 中文 设备与注塑机**开合模信号联动**： 开模 → 自动吹扫； 合模 → 立即停止。 在极短时间内吹干模具表面凝露水。 ### English The equipment is **linked with the opening/closing signal of the injection molding machine**: Mold opening → automatic blowing; Mold closing → stop immediately. It dries condensation on the mold surface in a very short time. --- ### （6）气帘阻隔防凝露 ### 中文 分型面气帘形成**干燥气墙**，隔绝车间湿热空气与冷模具接触，从根源防止凝露再次形成。 ### English The parting surface air curtain forms a **dry air wall**, isolating hot and humid air in the workshop from contacting the cold mold, fundamentally preventing re-condensation. --- ### （7）转轮连续再生 ### 中文 除湿转轮吸附饱和后自动进入**高温再生区**（120～140℃），脱附水分恢复除湿能力，实现**24小时不间断稳定运行**。 ### English After the dehumidification rotor is saturated, it automatically enters the **high-temperature regeneration zone (120~140℃)** to desorb moisture and restore dehumidification capacity, realizing **24-hour uninterrupted stable operation**. --- ## 3. 原理一句话总结（中英对照） ### 中文 先除湿、再加热、同步吹、气帘挡， 彻底解决低温模具结露问题。 ### English First dehumidify, then heat, blow synchronously and isolate with air curtain, completely solving condensation of low-temperature molds.
