Abstract

热熔胶涂布刮刀，主要特征在于采用了刮刀和热源于一体的设计，具有结构简单，操作简便，集熔胶、保温、输胶、刮胶为一体的特点。由于该设计采用流动的导热油加热，可使刮刀左右温度一致，热熔胶融化更均匀，从而达到供胶均恒，涂布量一致的涂布要求。同时，可避免电热丝加热方法因超温引起的热熔胶老化和黄变现象。

Description

[根据细则37.2由ISA制定的发明名称]　热熔胶涂布刮刀 技术领域
本发明涉及一种集熔胶、保温、输胶、刮胶为一体的新型热熔胶涂布刮刀。
背景技术
随着人们环保意识的不断提高，在很多需要粘合的两个界面中，环保的热熔胶被越来越广泛的使用。尤其在纺织面料、内衣材料、鞋材、汽车内饰等行业，一种直接将热熔胶熔化后涂布的短流程方式(可称为热转印涂层)在快速发展。目前在这种涂层方式中，胶的加热融化、输送、刮刀涂层是分开的：热熔胶通过熔体泵或挤出机被输送到带有电热系统的输胶管，再通过输胶管沿刮刀轴向的往返运动，把熔化的热熔胶输送到刮刀和被涂物间，随被涂物的移动，热熔胶刮涂到被涂物上。在上述现有的涂层方式中，由于热熔胶的加热是在输胶管内完成的，当热熔胶离开输胶管后，其温度将受外界环境的影响而变化，在输胶管沿刮刀轴向运动的涂胶过程中，最先输送到刮刀和被涂物间的热熔胶与最后输送到刮刀和被涂物间的热熔胶的温度存在一定差异，使得涂布区域温度不一致，可能影响最终的粘合效果。此外，采用电热丝加热的方式，对温度的控制有较高要求，如果电热丝表面温度过低，热熔胶将无法均匀融化，难以达到均匀涂布的要求；如果电热丝表面温度过高导致局部超温，则容易引起热熔胶老化和黄变的现象。
发明内容
本发明的目的是提供一种新型热熔胶涂布刮刀，其结构简单，操作简便，集熔胶、保温、输胶、刮胶为一体。
为达到上述目的，本发明的热熔胶涂布刮刀包括：刮刀主体，其具有形成在前表面下部的安装槽；以及刮刀片，设于所述安装槽中且通过一夹板固定至所述刮刀主体，其中，所述刮刀主体内形成有一第一通孔，一第二通孔和多个开孔；所述第一通孔沿刮刀主体的长度方向贯穿刮刀主体的上部且用于输入热熔胶；所述第二通孔沿刮刀主体的长度方向贯穿刮刀主体的下部且用于导入热油以加热所述刮刀主体、其内输入的热熔胶及其上安装的刮刀片；每个所述开孔位于安装槽上方，从刮刀主体的前表面向内延伸且与所述第一通孔相连通，用于输出经加热的热熔胶。
根据一实施例，所述的刮刀片、夹板及刮刀主体上均开有多个螺孔，通过多个螺丝依次穿过所述夹板、刮刀片和刮刀主体上的螺孔实现刮刀片的固定，所述多个螺孔沿刮刀主体长度方向均布，且在竖直方向上与所述开孔错开。所述多个螺孔的布孔宽度可以根据实际需要确定，只要确保能固定住刀片，并且与热熔胶输出孔的位置错开即可。较佳的，相邻两螺孔的中心距为60-120mm，螺纹尺寸为M4～M6*10，并且较佳的，所述螺孔位于两个相邻的开孔的中间位置，以避免热熔胶从开孔输出后往下流动时形成阻力，影响涂层的均匀度。
根据一实施例，所述刮刀主体由特殊合金钢1Gr13制成，其上部宽度为30-40mm，下部宽度为25-35mm，高度为50-70mm。
根据一实施例，所述第一通孔即热熔胶输入孔，沿刮刀主体长度方向左右贯通，直径为15-25mm；所述第二通孔即导热油孔，也沿刮刀主体的长度方向左右贯通，与第一通孔平行。较佳的，所述第二通孔的直径为10-15mm，两通孔的中心距为25-35mm。
根据一实施例，所述多个开孔，即热熔胶输出孔沿刮刀主体的长度方向均布，每个所述开孔的直径为2～3.5mm，每个所述开孔的中心轴线和所述第 一通孔的中心轴线之间呈-30～30°夹角。所述多个开孔的布孔宽度视涂布宽度确定，较佳的，相邻两开孔的中心距为30-60mm。
上述热熔胶涂布刮刀的工作原理为：
将恒温的导热油泵入第二通孔即导热油孔循环，提高刮刀和涂布区的温度到一定值，使刮刀内残余热熔胶熔融，并确保经过挤出机或熔体泵输送过来的热熔胶不至被冷却使胶体粘度提高，引起涂布困难和不匀。导热油的温度根据使用热熔胶的性能确定。
待刮刀内的热熔胶完全熔融后，通过挤出机或熔体泵的压力，将热熔胶通过多个开孔，即热熔胶输出孔输出，在压力和重力作用下，熔化的热熔胶下延到刮刀片和被涂物的接触区，即刀片的底部，随着被涂物的移动，在刮刀片的下切压力下，热熔胶被均匀的涂布到被涂物表面。

实施例
如附图2和3所示，显示了根据一实施例的新型热熔胶涂布刮刀的主视图和左剖视图，并在图中标注了每个部件的尺寸。需要说明的是，由于刮刀 主体较长，因此图2并非按照实际尺寸绘制，图中的双虚线为断裂线，表示长度的省略。以上附图主要为示意目的，而并非用于限制本发明。

本发明采用了刮刀和热源于一体的设计，具有结构简单，操作简便，集熔胶、保温、输胶、刮胶为一体的特点。设计采用流动的导热油对刮刀体进行加热，可使涂布区域温度一致，热熔胶融化更均匀，从而达到供胶均恒，涂布量均匀的涂布要求。同时，避免了电热丝加热方法，因电热丝表面温度过高导致局部超温，引起热熔胶老化和黄变的现象。
