Description

一种可快速接头的输送带
技术领域
本发明涉及一种可快速接头的输送带,所制得的产品在现场接头过程中,橡胶与骨架材料分离容易,涉及刀具操作较少,安全性高,可在各类输送带产品中应用推广,属于输送带技术领域。
背景技术
输送带是由橡胶覆盖胶材料、骨架材料、界面粘合材料组成的大型复合材料制件,广泛应用于矿山开采、钢铁冶炼、建材水泥、港口码头、火力发电等领域的物料运输,对重点国民经济的发展具有重要的支撑作用。受限于生产及运输条件,输送带单卷长度一般在数百米,而一条输送线往往数公里至数十公里,因此在输送带现场,需要将输送带拼接在一起,输送带接头的好坏直接影响输送带的使用寿命和输送线能否平稳顺畅地运行。输送带接头处的强度比正常带体的强度要低。一般用机械方式连接时,接头强度仅能达到带体强度的40-50%,冷胶方式质量比较好时,接头强度能达到60-70%,而热胶接头强度能达到80-90%(接头方法正确、无质量缺陷)。由于接头部位的强度比较低,如果胶接方法不正确,接头的强度就会更加低,在使用过程中造成断裂事故。
在热胶方式进行接头时,一般采用刀具,将接头处橡胶材料层层剥离,分离出骨架材料,然后按特定拼接方式,将骨架材料拼接,并上下覆上特定的橡胶,进行热压硫化,最终制备高强度的输送带接头。在此橡胶剥离过程中,目前技术多靠人工,手持美工刀,逐层分离,劳动强度大,耗时较长,并频发因美工刀崩裂造成人员受伤。同时,此环节对人员技术要求较高,若橡胶与骨架剥离不好或损伤骨架材料,会导致接头强度受损。因此开发一种便于橡胶骨架剥离的新型结构,降低人工操作时间、提高操作安全性,大幅提升接头效率和接头效果,具有重要的意义。
发明内容
本发明的目的在于提供一种可快速接头的输送带,在现场接头过程中,橡胶与骨架材料分离容易,安全性高,解决在输送带接头过程中人工效率低、频繁使用刀具分离橡胶与骨架材料造成的安全隐患等问题。
按照本发明提供的技术方案:一种可快速接头的输送带,其包括上覆盖胶,下覆盖胶,骨架材料,粘合层橡胶,第一高分子膜材料、第二高分子膜材料,在第一高分子膜材料、第二高分子膜材料两层高分子材料膜与骨架材料之间填充一层粘合层橡胶,在所述骨架材料上侧铺覆第一高分子膜材料,在所述第一高分子膜材料外侧铺覆上覆盖胶,在骨架材料下方铺覆第二高分子膜材料,在所述第二高分子膜材料外侧铺覆上覆盖胶,经冷压成型硫化,制备成可快速接头的输送带。
作为本发明的进一步改进,所述骨架材料为钢丝绳芯或高分子纤维织物。
作为本发明的进一步改进,所述第一高分子膜材料、第二高分子膜材料两层高分子膜材料之间的最大距离h1与骨架材料厚度h2的关系为h2≤h1≤h2+2mm。
作为本发明的进一步改进,所述第一高分子膜材料、第二高分子膜材料分别沿输送带纵向方向长度为1-10m,距输送带两端边部0-20mm,距输送带两侧边部0-50mm。
作为本发明的进一步改进,所述第一高分子膜材料、第二高分子膜材料的厚度分别为0.5-5mm。
作为本发明的进一步改进,所述第一高分子膜材料、第二高分子膜材料分别能换成橡胶片。
作为本发明的进一步改进,所述骨架材料为钢丝绳芯,所述第一高分子膜材料、第二高分子膜材料直接铺覆于骨架材料上,所述第一高分子膜材料、第二高分子膜材料外侧铺覆覆盖胶材料,经冷压成型硫化,制备输送带。
本发明与现有技术相比,其特点和优势主要表现在:
(1)本发明通过在输送带骨架材料与橡胶制件设置不与橡胶和骨架材料粘接的高分子膜,解决了传统结构输送带在接头时,工艺繁琐、频繁使用刀具带来的安全性问题;
(2)本发明通过设置高分子膜材料,在接头操作过程中,操作更加简洁规范,避免人工操作带来的接头强度受损的问题,有利于开发更高接头强度的输送带。

具体实施方式
下面结合具体实施例对本发明作进一步说明,但不作为对本发明的限制。
实施例1
如图1所示,钢丝绳芯为骨架的输送带,包括上覆盖胶a,下覆盖胶b,骨架材料c,粘合层橡胶d,第一高分子膜材料e-1、第二高分子膜材料e-2。本发明釆用在第一高分子膜材料e-1、第二高分子膜材料e-2两层高分子材料膜与骨架材料c之间填充一层粘合层橡胶d,在输送带的两端,在所述骨架材料c上侧铺覆第一高分子膜材料e-1,在所述第一高分子膜材料e-1外侧铺覆上覆盖胶a,在骨架材料c下侧铺覆第二高分子膜材料e-2,在所述第二高分子膜材料e-2外侧铺覆上覆盖胶b,经冷压成型硫化,制备成钢丝绳芯为骨架的可快速接头的输送带。所述高分子膜材料在输送带硫化后,可与橡胶材料和骨架材料分离。
优选地,所述骨架材料c为钢丝绳芯或高分子纤维织物。
优选地,所述第一高分子膜材料e-1、第二高分子膜材料e-2两层高分子膜材料之间的最大距离h1与骨架材料厚度h2的关系为h2≤h1≤h2+2mm。
优选地,所述高分子膜材料沿输送带纵向方向长度为1-10m,距输送带两端边部0-20mm,距输送带两侧边部0-50mm。
优选地,所述高分子膜材料的厚度为0.5-5mm,高分子膜材料也可换成橡胶片。
实施例2
如图2所示,钢丝绳芯为骨架的输送带,高分子膜材料e直接铺覆于骨架材料c上,高分子膜材料e外侧铺覆上覆盖胶a或下覆盖胶b,经冷压成型硫化,制备输送带。高分子膜材料e边侧填充粘合层橡胶d。
对于钢丝绳芯为骨架的输送带,两层高分子膜材料直接铺覆于骨架材料上,高分子膜外侧铺覆覆盖胶材料,经冷压成型硫化,制备输送带;或者在两层高分子膜材料与钢丝绳芯之间,铺设一层粘合层橡胶,在粘合层橡胶外侧铺覆高分子膜材料,然后再在高分子膜材料外侧铺覆覆盖胶材料,经冷压成型硫化,制备输送带。所述的高分子膜材料沿输送带纵向方向长度为1-10m,距输送带两端边部0-20mm,距输送带两侧边部0-50mm。
本发明通过结构设计,在输送带两端骨架材料与橡胶材料之间,设计一层输送带硫化后可以与骨架和橡胶分离的高分子膜材料。在输送带接头过程中,仅需用美工刀割开橡胶,便可轻易将橡胶与骨架材料整体分离,后稍加修整,即可进入下一步操作,大幅降低了人工操作时间,提高了接头效率,并显著降低了美工刀崩裂引发的安全风险。同时,接头环节更加标准化,减少了由于人员在橡胶、骨架分离过程中的操作不当,带来的接头强度受损的问题。所制得的产品在现场接头过程中,橡胶与骨架材料分离容易,涉及刀具操作较少,安全性高,可在各类输送带产品中应用推广。
