上折边装置及围字机
本技术涉及立体发光字围字机
,尤其涉及一种上折边装置以及使用该上折边装置的围字机。
技术介绍
立体发光字以其精美的外观备受欢迎,立体发光字的制作有手工和机械设备两种方式完成,随着工业水平的提高,机械设备制作立体发光字以效率高、性能稳定而越来越广泛的得到使用,立体发光字通常都是由围字机来制作完成以满足高效率的生产。中国专利技术专利CN104028594A的说明书公开了一种字边带成型围字一体机及字边带成型方法,字边带成型围字一体机包括围字机的机架,所述围字机的机架上依次设有直角成型对辊、钝角成型对辊、直角成型辊组以及锐角成型辊组,字边带经过直角成型对辊、钝角成型对辊、直角成型辊组以及锐角成型辊组的压合成型,得到具有三个侧边的加强筋部,加强筋部的第三侧边与第一侧边交叉结合,使字边带的整体强度增加,增加了由字边带加工形成的围字的使用寿命。然而,在折边成型过程中,使用壁厚超过1毫米的边带材料时,折边力量加大,作用力作用在垂直边带输送方向的幅面上,会使得边带在折边过程中产生位移,导致折边部位越来越小,最终边带将脱出折边辊轮,而材料使用低于1毫米较薄的边带时,成型对辊从上往下压合边带时,作用力会压到边带幅面上,会导致边带幅面变形,从而影响边带成型效果,进而造成立体发光字制作质量低下。专利技术人虽然之前设计过一种边带折边承托装置,包括安装座,所述安装座上设有相对设置的两块安装板,两块所述安装板之间转动安装有折边辊,所述折边辊一端设有折边槽,所述折边辊的另一端与相对的安装板之间设有安装间隙,所 ...
