This is concept stadium. As you can see I decided to use screw/worm wheel which will move silicon into tube.
For now there few parts - screw/worm wheel and bushing/basket which will aver even amount of seal.
Next step is to add rolers that will turns the screw/worm and will provide even amount of seal (amount of seal will depend of the speed of rollers)
Small update - gears... hmm... hard to decide what to do with this concept... I need to take my mind about it... maybe some belt? :]
As you can see I have changed the dsign - I need ime to finish it. Last picture shows the tube where the "worm" will go - inside this tube. I will add some belt and bevel gear to transver movment from roller to worm.
Last update - finished design.
Sorry for my poor english... :(
This version of design is finished. I have in my head some variations of it but I don’t have free time to present all of them :(
Design is simple - so it may be the good one :) I think that everyone understand the idea of it.
Base of this idea is to use worm/screw - something like we have in injection molding...
About the design...
Near the nozzle we have roller with rubber for better friction. Then we have gears that transfer rotation of the roller to belt, gear and finaly to worm/screw.
This type of solutions guarantee that the amount of silicone in nozzle will be always same and no matter how fast you go with applicator... if you go slow - worm rotate slower, if faster - worm rotate faster... and you always get the same silicone layer on your wall :) equal to the distance that the applicator was moved...
First idea was to put worm/screw and gears into sealant nozzle but then I decided to put all gears outside. Why? Now you only need to clean worm/screw and you don't need to clean all parts. I think that it's hard to clean gears from sealnt etc...
PS. Renders are welcome :)
