过去,我厂铸工车间砂处理工部使用的输送皮带,其两端头的联接,一般采用以下两种方法:一种是重叠铆制,即将输送带两端重叠一段用铆钉联接。这种方法只适于直接输送物料,中途不能用刮板卸料。另一种是用皮带卡子联接。这种方法联接的皮带在输送干砂子时,因皮带卡子的间隙易漏进砂子而使卡子寿命缩短,一般情况下,寿命只有5～6个月左右就需更换新卡子,而更换新卡子时要剪去旧卡子与输送皮带相接的部分,更换几次后,由于输送皮带被剪短只好再增加新的接头。后来我们采用了粘接法,共安装皮带
In the past, the conveyor belts used by the sand processing department of our foundry’s workshop, the two ends of which are generally connected by the following two methods: one is overlapping riveting, the overlapping section of the conveyor belt is to be connected by rivets. This method is only suitable for direct delivery of materials, half-way can not be discharged with a scraper. The other is linked with a belt clip. This method of coupling the belt in the transport of dry sand, because of the gap between the belt clip easy to leak into the sand and make the clip life is shortened, under normal circumstances, the life expectancy is only about 5 ~ 6 months to replace the new clip, and replace the new clip To cut off the old clip connected with the conveyor belt part, after several replacement, as the conveyor belt is cut short and then add a new connector. Later, we used the bonding method, a total installation of the belt
