Description

Delivery mechanism of slitting machine

technical field

The utility model relates to the technical field of steel material cutting equipment, in particular to a paper receiving mechanism of a slitting machine.

Background technique

When rolling steel to make steel coils, it is necessary to add a layer of paper film to the surface of the steel to avoid damage to the surface of the steel due to friction during transportation. When unrolling steel coils and cutting steel plates, it is necessary to separate and recycle the paper film. As shown in Figure 1, the existing steel plate slitting machines used for unrolling steel coils all have paper delivery mechanisms for recycling paper films. The displaced left and right shaft seats (A, B), and the tapered rewinding shaft C respectively arranged on the left and right shaft seats. When the paper take-up mechanism is working, the distance between the left and right shaft seats will be narrowed, so that the conical rewinding shaft clamps the paper reel of the rewinding paper film from both sides, and then the conical rewinding shaft is rotated to realize the rewinding of the paper reel. . However, since the conical winding shaft is in line contact with the paper reel, when the distance between the left and right shaft seats is too large, it is easy to cause the paper reel to slip due to insufficient clamping; when the distance between the left and right shaft seats is too small, the There is a risk of tearing the paper roll.
