高频机为什么老打火?打火该怎么办?

2018-10-19临安远方电子下载文件:暂时没有下载文件
 

为什么高频熔接间中会有打火现象?导致的原因基本有以下六种:
1、模具水平调整的不够平整,有间隙,容易导致打火。
2、在热合过程中高频电流调得过大,容易使模具打火现象。
3、模具打火后没有采用适当的办法处理高频模具打火留下的灰尘和黑点。
4、高频上模模具还没有完全和下模模具接触就开始发射高频机电流。
5、高频模具表面的绝缘材料没有得到适当的处理

6、热合材料不干净比如有小颗粒的层土。
当上、下模电极接触时,引起的打火出现现象严重的会将面料、模具及发振筒受损。


高周波塑胶熔接机打火怎么办?芯片防打火装置有什么优势?
高周波机打火一直以来都在困绕着我们,在生产中一不小心就会出现打火的现象,轻则烧坏产品或包装材料,严重的会将模具烧出缺口,带来的后果是需要马上停止生产,维修模具,由此会严重影响生产进度。
浙江临安市远方电子设备有限公司的技术部经过多年研究,开发出高性能的高频机专用电脑芯片防打火装置,它有着无可比拟的优点.通过电脑芯片对整机的管理,使高频机彻底解决了烧模具,烧接点,抢电等常见的问题,更好的保护电子管及相关器件受电流的冲击,大大提高了机器的使用寿命.

在高周波熔接机的生产过程中我们尽量做到几点:
1、放高周时上电极和下电极不要直接接触;
2、上下模具一定要调整水平位置;
3、接触上下模具的部位不可以有灰尘和杂物;
4、定期清理振荡桶的灰尘,保持机器在干净通风的状况下工作;
5、当一旦有打火的现象发生后,请及时的清理上下模具,烧黑的部位一定要清洗干净(可用酒精清洗)。
6、每次在调试新的模具,电流都应该调整至回0.2A。然后利用铜调器慢慢的把电流调至合适的电流热合。
7、高频模具下面应采用一定的结缘材料(市场常见的绝缘材料有:绝缘纸、四氟、高温布、高温胶带、硅胶、牛皮纸、黄蜡纸等绝缘材料)有效地防止高频再次击穿所需要的焊接产品。
8、电容片在调节过程中调节的幅度不应过大,应当慢慢的调试相应的范围,电容片在生产过程中边缘出现打火现象,可能是电容片的边缘没有处理干净又铝板毛刺,关系不大,只需要用砂纸处理打磨光滑即可。
9、振荡桶在生产过程中出现的打火现象主要有电容片,高压管座等打火。处理方式和电容调节一样。
