Coupe linTaire
Coupe linTaire
(OP)
Bonjour notre compagnie recherche un mécanisme qui effectuera une coupe linéaire au bas d'un ballot de peat moss. Donc, une simple lame fera l'affaire pour couper le plastique mais le mécanisme doit se retracter complètement après la coupe pour ne pas bloquer la suite du ballot sur le convoyeur. J'ai penser à un verin mais la vitesse est trop lente étant donné qu'ils sont conçu pour des grosses charges ce qui n'est pas le cas ici
Merci beaucoup à vous tous!!
Merci beaucoup à vous tous!!





RE: Coupe linTaire
High speed cylinder retraction can be obtained with two-stage pumps.
Any motion can be sped up with suitable linkage.
A lot of farmers use a modified chainsaw blade to slice up hay bales.
RE: Coupe linTaire
What material is actually being cut?
How long is the cut?
Is the bale moving along a conveyor?
How is it being moved?
How fast?
Post sketches or images of what the cutting mechanism would be mounted to.
Could the bale just be pushed/pulled past a fixed/rotating cutting blade?
RE: Coupe linTaire
what depth cut?
What configuration?
RE: Coupe linTaire
Our blades are about 36" in diameter and are essentially continuously sharpened with an appendage like that on a meat slicer. On the rolls the blade feeds into roll and on the bails the blade has a fixed axis. It would be easy to make the blade retract.
These blades are extremely sharp and have cut people try to check the sharpness who didn't realize it until the saw the blood.

(1) So the original poster should determine - from his own measurements!!! - the shear strength of his variety of peat moss in the fields he is cutting and bagging.
(2) Determine his cross section area of the peat moss "chute" where the moss is being extruded.
(3) Add a 15- 25% margin and calculate the needed force to shove his "blade" through the cross-section of peat moss - assuming he measured the resistance based on his chosen blade thickness and blade cutting angle and the baseline "guillotine" angle of the edge of the blade -
(4) then buy a plunger and dual-mode piston to deliver that much force over than long a length to cut all the way through his "chute" - and set the cycle time to get the quantity he wants per hour.
Seems straight-forward. (Be nice to get some feedback from that OP.)
