Description

一种螺旋送料内加热注塑机
技术领域
本发明涉及一种螺旋送料内加热注塑机，属于注塑机技术领域。
背景技术
注塑机又名注射成型机或注射机，它是将热塑性塑料或热固性料利用塑料成型模具制成各种形状的塑料制品的主要成型设备。注塑机的工作原理与打针用的注射器相似，它是借助螺杆的推力，将已塑化好的熔融状态的塑料注射入闭合好的模腔内，经固化定型后取得制品的工艺过程。常见的注塑机多采用电加热，利用分布在机筒外的加热圈，对机筒内的材料进行加热塑化。这种方式热熔率不高，只能使用电能，无法使用其它热能，无法提升节能效果。

所述挤出机头包括挤出头、模具头，所述挤出头内设置有出料通道，所述出料通道与外筒、内筒的左端相连通；所述挤出头左端设置有模具头，所述模具头用于挤出成型塑料件。
所述内筒外壁上螺旋片的间距由右端向左端逐渐变窄。
所述进料装置包括进料斗、进料螺杆、进料电机，所述进料斗设置在外筒右端顶部，所述进料螺杆设置在进料斗内，所述进料电机与进料螺杆相连接。
作为优选方案，还包括保温层，所述保温层套接在外筒外表面。
有益效果：本发明提供的一种螺旋送料内加热注塑机，通过内筒的结构设计实现了对塑料原料内加热方式，这种加热方式可利用燃烧机的提供的热量，燃烧机可利用垃圾燃料，有利于节能、环保。另外，挤出机头可按需求进行更换，挤出不同形状的成型塑料件。本设计有效的提高了融料效率、塑料件的生产率，节约了生产成本。
附图说明
图1为本发明的结构示意图；
图2为内筒的结构示意图。
具体实施方式
下面结合附图对本发明作更进一步的说明。
如图1、图2所示，一种螺旋送料内加热注塑机，包括机架1、外筒2、挤出机头3、进料装置4、转动电机5、内筒6、燃烧器7，所述内筒6设置为中空结构，内筒6外壁设置有连续的螺旋片8，内筒6右端联通设置有进火管9，内筒6左端联通设置有出火管10，所述进火管9上设置有链轮11，所述链轮11通过链条12与转动电机5相连接；所述内筒6外套接有外筒2，内筒6与外筒2之间设置有空隙，所述外筒2两端均设置有轴承13，所述进火管9、出火管10穿过轴承13，并与轴承13转动连接，所述外筒2固定设置在机架1上，所述外筒2右端设置有进料装置4，所述外筒2左端设置有挤出机头3，用于挤出成型塑料件；所述内筒6的进火管9与燃烧器7相连接。
所述挤出机头3包括挤出头31、模具头32，所述挤出头31内设置有出料通道33，所述出料通道33与外筒2、内筒6的左端相连通；所述挤出头31左端设置有模具头32，所述模具头32用于挤出成型塑料件。
