Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine spray powder recovery device. Background Art

[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. In order to prevent the paper from sticking to the printing plate during printing, powder is usually sprayed on the printing plate to facilitate separation of the paper from the printing plate. However, powder will fly during the spraying process, resulting in powder waste. In order to save powder, a powder recovery device is usually added. There are at least the following disadvantages in the use of existing powder recovery devices: 1. When using the existing powder recovery device, the powder attached to the inner wall of the shell cannot be recovered by a fan, resulting in powder waste; 2. Since the position of the air outlet of the existing recovery equipment is fixed, the efficiency of recovering powder is not high. Therefore, we have introduced a new printing press powder recovery device. Utility Model Content
