Description

一种辊子及其辊压装置 技术领域
本实用新型涉及一种用于研磨或粉碎的辊子，还涉及包括这种辊子的辊压装置。
背景技术
辊子一般是用在辊压装置中，用来研磨或粉碎物料。通常辊子辊压物料的时候是利用设置在辊子基体表面的凸起实现的。现有设备中的凸起主要是通过在基体表面设置数个高于基体表面的柱钉，柱钉与柱钉之间有间隔，通过柱钉来挤压物料，以达到研磨或粉碎物料的效果。但是，柱钉辊在挤压或粉碎物料时一次成品率不高，为10％～16％，另外柱钉辊的使用寿命为12000～15000小时，使用2100小时的磨损量3.2mm。
实用新型内容
本实用新型的目的在于提供一种一次成品率高的辊子和辊压设备。
本实用新型的目的是通过以下技术方案实现的：
一种辊子，包括有辊轴和基体，在所述基体上设置有棱条，所述棱条由凸块紧密排列构成，且凸块在辊子轴向连续。这样的设计，能够有效提高辊子辊压物料时的一次成品率。
为了进一步提高辊子的使用寿命，所述凸块与基体是通过设置在基体上的凹槽来连接的，且所述凸块通过嵌入的方式位于凹槽内。这样的设置有效的提高辊子的使用寿命，且避免凸块在沿辊子基体表面的方向产生裂纹。上述的嵌入方式可以为过盈配合，也可以为间隙配合，所述间隙配合可以为通过金属胶粘剂粘结固定或者焊接方式连接固定。优选为金属胶粘结剂粘结固定的间隙配合，这种配合在工艺上较过盈配合好实现，也避免了凹槽热胀冷缩对连接部位的影响。
为了进一步提高使用寿命，所述凸块的底面宽度不小于凸块与辊面相交面的宽度。即使凸块在辊子直径方向上破裂，也不影响辊子的使用。
为了进一步提高使用寿命，所述凸块的截面形状可以为矩形、梯形、L形、T形、凸形等。凸起小块优选的截面形状为梯形，加工容易、使用中即使有磨损也不易脱落。
为了进一步提高辊子的耐磨性，所述凸块高出辊面的高度占凸块整体高度的15％～30％。同时提高了耐磨性和使用寿命。
为了进一步提高辊子的一次成品率，凸块高出辊面的高度为4～7mm。
为了进一步提高辊子的使用寿命，所述组成同一棱条的凸块高出基辊面的高度一致。
上述凸块在基体表面排列形成的形状可以是一字形、Z字形、人字形、弧形等。优选为一字形，利于加工凹槽和凸块，有效的降低了成本。
为了进一步提高辊子辊压物料时的一次成品率，在所述辊子的两端设置有挡边，所述挡边镶嵌在相邻两条棱条之间。作为优选，所述挡边与棱条等高，进一步提高一次成品率。
上述凸块可以为一种或者两种尺寸规格，这样可以组成任意宽度的凸起，降低采购成本，减少模具费，增强了凸起的通用性和互换性。
在本实用新型中，所述的辊子可以为辊轴和基体为一体的整体式辊，也可以是辊轴和基体为两个部件的组合式辊。
有益效果
本实用新型不仅提高了一次成品率，同时还提高了使用寿命和耐磨性。本实用新型一次成品率可以达到22％～30％，使用寿命可以达到15000～20000小时，且使用2100小时后磨损量仅为2.5mm。
