Description

Reel positioning device

Technical Field

The utility model particularly relates to a spool positioner.

Background

At present, most aluminum plate and strip processing enterprises generally need to configure some finishing machine columns for cleaning, straightening, trimming, slitting and other subsequent procedures on aluminum coil rolled by a rolling mill; the common characteristic of these finishing trains is that they are equipped with uncoilers and reels for uncoiling the aluminum coil, i.e. for conveying the strip into the subsequent mechanisms for cleaning, straightening, trimming, slitting and the like.

At present, an uncoiler with a partial finishing machine row adopts a mode of installing a carrier roller at the bottom of a shaft head of a reel to support and position the reel, and the specific structure is shown in figure 1.

The disadvantages of this supporting and positioning method include: 1. when an uncoiled strip runs forwards during production of a train, the strip needs to bear forward pulling force applied by a coiler, the pulling force also acts on a reel of the uncoiler, so that the reel needs to bear forward acting force, when the thickness and the width of the strip are increased, the forward acting force borne by the reel is correspondingly increased, at the moment, a roller at the bottom of a shaft head cannot fix the reel, and the shaft head of the reel and a shaft sleeve swing together in the horizontal direction (the left-right direction in figure 1); as a result of the oscillation, the parallelism between the reel and other roller systems (such as deflection rollers) of the train is changed, so that the strip material has defects of adhesion, wrinkles and the like, and the product quality is seriously affected; 2. the common solution to the above problem is to redesign the supporting mechanism for processing the shaft head of the reel, then remove the old mechanism and reinstall the new mechanism; the method is time-consuming and labor-consuming, not only has large workload and long downtime, but also needs to spend a lot of processing cost.
