Dust Collector Sucking up conveyor belt6/6
We have a two head 52 inch timesavers widebelt sander. We cannot sand ¾” thick material because the dust collector will suck the conveyor belt into sanding heads and sand down the conveyor belt. We have tried to cut the suction down by having the 10” blast gate only open half way. Still has not worked.
Hopefully someone with more knowledge will chime in but it sounds like a belt problem not a dust collector problem.
Is the tension on the belt correct? Are you sure it is the suction of the collector or is it the belt binding and bunching up?
Just sounds odd, the amount of suction needed to pick up a rubber belt is tremendous. Run it without the collector on and see if you have the same problem.
have you tried calling Timesavers?
with the belt not moving can you see the vacuum lifting up the belt?
Thanks for all the feedback and suggestions. We have had this problem for quite some time the 1st conveyor-belt we bought directly from time savers and we had the same issue. We purchased the 2nd belt from another supplier due to the belt from timesavers being sucked up into the sanding belts and due to cost.We have spoken to technical service at time savers and have not been able to provide us much assistance. We have tried adjusting and fighting the belt. The belt is actually pretty tight. I will try to take a picture or video of the belt getting sucked up when we don't have the conveyor on. I am out of the shop right now.
Drill one billion holes in the belt to make it porous. Shouldn't get sucked up if air can pass through it.
Timesavers is on the hook to provide your solution, are they not? They may drag their feet, but it is their machine. I hope they sprung for the replacement belt. As I see it, this is not a suction problem as much as it is a responsibility problem for the maker, and a motivation problem for you.
There are many machines like yours in the world - how do they deal with it? Woodweb may have a member that chimes in, but most likely, if they have a similar machine, they don't have the problem.
I would try to drill many 1/4" holes in the platen across its width, under the feed belt and hook up a vacuum pump to see if you can counter the top suction. Or perhaps a gate/diversion system that would take suction off the machine heads and divert an adjustable portion of it to the feed belt. But first, I would do everything I could to get Timesavers to stand behind it. Then I'd get them to do the diversion experiment, or other solutions you propose.
how old is this machine?
