Question

hopper bar应当如何翻译？料斗支杆？还是料斗杆件？

Leave a slight clearance gap between the hopper bar and the carton edge.
在料斗杆（猜想料斗上是否所有的杆件均起支撑作用？就叫“支撑杆”）与纸盒边缘之间留下少许空隙。

Answer 1

haha, nice to meet you.
only a suggestion, you can look into the manual and find which line or face on the hopper matches with the carton edge with the said gap.or go to site to find the part.and then make a name and keep the same name in all the paper.this will be perfect. or just translated as leave a slight clearance gap between the carton edge and the HOPPER, this is enough. because I guess the carton is positive, the hooper can be adjusted while installing and production. normally, on this sort of equipment, the hopper is adjusted to a position that during prodution and any time can not damage the carton.technician knows this.
it is clear which part of the hopper may 'collide 'with the carton on a certain edge.

Best regards.
