Description

Technical Field

[0001] This utility model relates to the field of display rack technology, specifically a display rack for rubber rollers of a printing press. Background Technology

[0002] Printing press rubber rollers are roller-shaped products made of metal or other materials as the core and covered with rubber through vulcanization. Printing press rubber rollers generally consist of an outer rubber layer, an outer hard rubber layer, a metal core, a roller neck, and ventilation holes.

[0003] A search revealed a patent, CN214987358U, which discloses a rubber roller placement rack for a printing press. The rack includes a base plate with two support rods fixedly connected to its top. Several placement components are arranged inside the support rods. Each placement component includes a first protective half-cylinder, a second protective half-cylinder, and two fixing discs, providing placement and protection. Each placement component has two fixing components to secure the second protective half-cylinder. When placing the rubber roller, it can be placed inside the first protective half-cylinder, with the roller's shaft positioned within its shaft hole, thus fixing the roller within the first protective half-cylinder. The second protective half-cylinder can then be moved to cover the first, sealing the rubber roller within it. This prevents the rubber roller from being exposed to the outside environment, accumulating dust, affecting its use, and avoiding the problem of the shaft easily rusting after prolonged placement.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes the placement of rubber rollers within the first and second protective half-cylinders. However, in actual operation, printing presses require a large number of rubber rollers. When placing a large number of rubber rollers using the placement rack described in the comparative document, a large number of first and second protective half-cylinders are required. This results in an excessively high overall height of the placement rack, making it difficult to retrieve and place the rubber rollers. Therefore, there is an urgent need in the art to improve the rubber roller placement rack for printing presses to overcome the shortcomings of the prior art. Utility Model Content
