Abstract

带轴头的中空橡胶辊，包括辊芯、胶体及辊芯两端的轴头，其特征在于所述的辊芯为中空状辊芯，在辊芯的轴头端截面开有散热孔。散热孔与中空状辊芯是相通的，具有散热通风的作用，在运转过程中，由于空气的流动使辊芯表面由于风冷作用及时散热，降低胶体表面的热积聚，从而避免胶体爆裂。

Description

带轴头的中空橡胶辊
                            技术领域
本实用新型涉及一种橡胶托辊。
                            背景技术
ABS树脂切粒机上的橡胶辊是切粒机上的关键部件和易损件，ABS树脂料条经橡胶辊表面输送至切刀上切成所需大小的粒状塑料。橡胶辊的结构是由辊芯和辊芯外的胶体以及辊芯两端的轴头组成。现有的橡胶辊的辊芯轴头端的截面上没有散热通风孔，由于在生产运转过程中，长期的高压力运转使表面胶体产生大量的积聚热，致使胶辊表面的胶体爆裂而污染原料，从而影响使用效果。其它类似设备上的橡胶辊也存在同样的情况。
                            发明内容
本实用新型所要解决的技术问题是提供一种能及时散热的带轴头的中空橡胶辊。
本实用新型带轴头的中空橡胶辊，包括辊芯、胶体及辊芯两端的轴头，其特征在于所述的辊芯为中空状辊芯，在辊芯的轴头端截面开有散热孔。
散热孔与中空状辊芯是相通的，具有散热通风的作用，在运转过程中，由于空气的流动使辊芯表面由于风冷作用及时散热，降低胶体表面的热积聚，从而避免胶体爆裂。
所述的散热孔最好为斜孔，设备在运转过程中能够加强空气的流动。散热孔的数量在本实用新型中不作限制。散热孔优选为具有斜坡口的散热孔，斜坡口为30～45度角，更优选30度角。
本实用新型的优点：
橡胶辊在运转过程中辊芯内由于空气的流动，能够及时散热热量，从而降低胶体表面的热积聚，避免了胶体爆裂，提高了橡胶辊的使用寿命，保证了原料的质量。
                             附图说明
图1为本实用新型的结构示意图；
图2为图1的A向视图；
图3为图2中的C-C视图；
图中：1辊芯  2胶体  3轴头  4散热孔  5斜坡口
                            具体实施方式
图1～3为本实用新型的优选结构示意图，以下结合附图说明。
如图1，橡胶辊由辊芯1、胶体2、辊芯两端的轴头3组成，辊芯1呈中空状，在辊芯轴头端截面上均匀开有三个散热孔4，散热孔具有斜坡口5，如图3所示，斜坡口具有30～45度，优选30度的倾斜角。
橡胶辊在运转过程中，外界空气通过散热孔与辊芯内产生空气流动(在同一旋转方向上，从一端进气、一端出气)，及时散热热量，从而降低胶体表面的热积聚，避免了胶体爆裂。
