Description

一种注塑机料筒 技术领域
本发明涉及一种注塑机料筒， 尤其是一种可以同时对多种原料进行单 独干燥调质的一体多厢分级塑料烘料筒。 背景技术
在塑料制品的注塑过程中， 由于通常要求原材料的含水量不超过千分 之五， 因此在注塑前需对原材料进行干燥调质处理， 一般工艺是对原材料 在 90〜200°C下进行 1〜6小时的干燥调质处理。 现有的注塑料筒都是在恒 温桶之前设专用调质干燥装置， 完成干燥调质后再将原材料送入恒温桶， 在此过程中， 大量的热量被散失， 同时运送过程中也容易造成原材料的二 次污染， 不但耗费人力物力， 对产品的质量也有很大的影响。 另外， 在多 层复合塑料制品的注塑过程中， 由于不同的原材料其干燥调质过程采用不 同的温度与时间， 因此需要多个专用调质干燥装置来处理多种不同的原材 料，上述问题尤为严重。公开日为 2009年 7月 29日，公开号为 CN101491935A 的中国专利文件公开了一种注塑机料桶温度同步控制系统及方法， 旨在提 供一种注塑机中各段料桶温度同步系统及其控制方法。 该系统包括位于料 桶各段位置处的若干电加热器和具有对应安装位置的温度传感器， 各温度 传感器通过信号线连接至温度设定模块， 温度设定模块、 温度同步控制模 块和 PID控制模块通过信号线依次连接， PID控制模块通过信号线连接至前 述各电加热器。 本发明在注塑机各段料桶温度设置不一致或者散热情况不 一致的情况下， 快速地进行控制使各段温度同时达到设定值。 在实时的检 测到各段料桶温度设定值和实际值之间的误差后， 获得各段的控制输出去 控制各段的加热器的工作， 实现各段的温度精确控制， 可以达到使注塑机 各段料桶温度同步、 快速达到设定温度的效果。 该方法对单一料筒提出了 分段控制温度的设想， 有利于提高控温精度， 但无法解决注塑过程中原材 料转送环节能耗大、 工人劳动强度高及容易导致原材料二次污染而影响产 品质量的技术问题。 发明的公开
本发明为解决现有注塑生产过程中原材料转送环节热量损失大、 工人 劳动强度高及容易导致原材料二次污染而影响产品质量的问题， 提供一种 能耗小、 省时省力且不会出现二次污染、 产品质量好的一体多厢分级塑料 烘料筒。
本发明为达到上述技术目的所采用的具体技术方案为： 一种一体多厢 分级塑料烘料筒， 包括组合式料筒、 电热鼓风系统、 温度控制系统， 所述 的组合式料筒由两个或两个以上分料筒组成， 每个分料筒设有独立的分进 料口与分出料口及可独立进行开关控制的分支鼓风口， 所有分料筒的分出 料口连通设于分出料口下方的恒温仓， 恒温仓的下部设有总出料口及主送 风口， 恒温仓及每个分料筒都具有独立的温度控制系统。 将现有技术中单 独、 分开设置的原材料干燥调质装置以分料筒的形式集中设置在注塑机料 筒的上部， 每个分料筒设有独立的分进料口与分出料口及可独立进行开关 控制的分支鼓风口， 注塑机料筒的下部作为恒温仓使用， 恒温仓的下部设 有总出料口及主送风口， 恒温仓及每个分料筒都具有独立的温度控制系统， 这样， 多种原材料可以在各个分料筒内采用不同的温度与时间独立进行干 燥调质， 全部干燥调质完成后只要开启分出料口， 分料筒内的原材料就可 以直接进入恒温仓， 在恒温仓混合及调温处理后即可进行注塑操作。 由于 多种原材料的干燥调质在同一个大容器内完成， 不但避免了分体结构中存 在的转运热量损失大、 工人劳动强度高的问题， 而且不存在转运过程中可 能出现的二次污染问题， 确保了产品的质量。 需要说明的是， 分料筒的数 量通常与所需干燥调质的原材料种数一致， 即几种原材料使用几个分料筒， 另外， 也可以将辅助材料置于分料筒内加热， 这时分料筒的数量可以多于 原材料的种数。 在分料筒的体积上， 也可以根据原材料或辅助材料的多少 来确定分料筒的大小， 即分料筒可以采用同等大小的结构， 也可以是大小 混合的结构。
作为优选， 分料筒的分支鼓风口通过分支鼓风线路并联在一鼓风系统 中， 每个分支鼓风线路上均设有分气阀及分支加热装置， 所述恒温仓上的 主送风口通过主鼓风线路与分支鼓风线路并联在同一鼓风系统中， 主鼓风 线路上设有主气阀及主加热装置。 由于整个系统采用热风加热， 采用同一 鼓风系统可以节约成本， 另外， 每个分料筒及恒温仓均可以通过气阀及加 热装置控制加热温度及加热时间。
作为优选， 分料筒上部的容置空间与分出料口、 分支鼓风口之间设有 分格栅网， 恒温仓与总出料口、 主送风口之间设有主格栅网。 在分料筒及 恒温仓内设置格栅网， 可以在分料筒或恒温仓的底部区域形成一定的空间， 这一空间可以使进入分料筒或恒温仓的热风均匀地进入分料筒或恒温仓原 材料区域， 保证原材料的加热均匀。
作为优选， 每个分料筒的分进料口上都设有翻盖， 翻盖与分料筒铰接， 翻盖上都设有透气口， 恒温仓的上方也设有出气口。 翻盖结构可以方便原 材料的加入， 透气口用于排出分料筒的湿气。 同理， 恒温仓的上方也相应 设有出气口。
作为优选， 恒温仓内设有搅拌装置。 搅拌装置可以使各个分料筒内流 出的原材料迅速混合均匀， 保证恒温仓内的各种原材料均匀程度。
作为优选， 分料筒与分料筒及分料筒与恒温仓之间均设有绝热分隔层。 绝热分隔层的作用一是保温， 二是保证各分料筒及恒温仓的相对独立性， 防止他们之间出现过多的热量传递， 从而影响各自的温度调节。
本发明的有益效果是： 它有效地解决了目前注塑生产过程中原材料转 送环节热量损失大、 工人劳动强度高及容易导致原材料二次污染而影响产 品质量的问题， 本发明结构简单、 能耗及劳动力成本低、 工效高、 产品质
