Description
Technical field
The utility model relates to a kind of flux-cored wire production facilities, particularly a kind of flux-cored wire belt-type powder feeder.
Background technology
At present, the powder feed system of flux-cored wire forming machine generally adopts the belt-type powder feeder, as patent documentation CN201543973U, on August 11st, 2010 disclosed wire rolling mill powder feeder, when following powder, before the medicinal powder of pressing close to most belt surface leaves belt, do entad motion around the powder feeder front axle center, when the adsorption affinity between medicinal powder and the belt was not enough to centripetal force is provided, medicinal powder then can be thrown out of, leave belt surface, drop in the U type groove of steel band.Shaft diameter is generally 15～25mm before the domestic existing powder feeder, considers thickness of belt 1.8～2.5mm, and the radius of curvature of actual belt at the front axle place is 10～15mm, and this moment, radius of curvature was bigger, according to the formula of centripetal acceleration: a=v
2/ r, its centripetal acceleration is less, and required centripetal force is less.The threshold reduction of centripetal force can cause the adsorption affinity between medicinal powder and belt to be more prone to satisfy the demand of centripetal force, promptly can cause bottom medicinal powder to be bonded on the belt easily, and in the process that belt moves backward, be shed on the powder feeder frame because of factors such as vibrations gradually.Can waste part medicinal powder so on the one hand, cause the rising of productive costs, on the other hand, can make down this link of powder be absorbed in a uncontrollable condition, influence the stability of filling rate.
