Storage frame

Abstract

The invention discloses a storage frame which comprises a rack, a fixed guide roller set and a movable guide roller set. The movable guide roller set comprises a moving frame, a moving drive device and multiple movable guide rollers arranged on the moving frame. When the storage frame is used normally, the moving guide roller set moves to the position above the fixed guide roller set, and a base material penetrates gaps between the movable guide roller set and the fixed guide roller set and does not make contact with the guide rollers so that damage to the surface of the base material by the guide rollers can be avoided effectively. Before materials are received, materials are stored by moving the movable guide roller set downwards to the position below the fixed guide roller set, and material receiving is facilitated; and after material receiving is completed, the movable guide roller set moves upwards to the position above the fixed guide roller set, and normal feeding is conducted. By means of the structure, contact between the base material and the guide rollers is reduced, and the abrasion rate of the surface of the base material is reduced to the maximum degree; and the storage frame is more compact in structure and lower in manufacturing cost.

Description

technical field [0001] The invention relates to a storage rack for optical protective film. Background technique [0002] The material storage rack is an important part of the coating machine and printing machine for roll changing and docking. When the traditional storage rack is working, the base material and the transition guide roller on the storage rack are in contact, that is, the base material and the guide roll are always in contact, which can easily cause damage to the surface of the base material, while the optical The protective film coating machine has particularly strict requirements on the surface scratches of the substrate, which requires the guide roller with as little contact with the substrate as possible, and the traditional storage rack has been difficult to meet the needs of use. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a material storage rack, which can reduce the contact...
