Abstract

The invention provides a negative pressure type adsorption platform. The negative pressure type adsorption platform comprises a platform main body, a belt mechanism, a plurality of negative pressure generators and an air channel switching mechanism; a plurality of air cavities are formed in the platform main body, the air channel switching mechanism can control on-off of different air cavities and air channels of the negative pressure generators correspondingly, and when the air channels are on, the negative pressure generators form negative pressure environments in the air cavities; the belt mechanism is installed on the platform main body, and a plurality of first vent holes are formed in a belt of the belt mechanism; and a plurality of second vent holes communicating with the air cavities are formed in the platform main body. The air channel switching mechanism can be used for controlling on-off of different air cavities and the air channels of the negative pressure generators correspondingly, so that the number of the air cavities in the negative pressure state is controlled, and finally the adsorption area is adjusted to adapt to different printing media; and the negative pressure in the air cavities acts on the printing media through the second vent holes communicating with the air cavities and the first vent holes of the belt mechanism, continuous and stable adsorption force is kept, the printing media is completely adsorbed to the belt, and printing disorder is avoided.

Description

technical field [0001] This application relates to the technical field of printers, in particular to a negative pressure adsorption platform. Background technique [0002] The function of the printing platform is to support the printing medium. When printing, the nozzle acts on the printing medium on the printing platform to complete the printing action. There are two types of printing platforms in the prior art: one is a stationary platform without a belt, and the printing medium directly slides over the printing platform during printing; the other is a moving platform with a belt, and the belt moves from the printing platform during printing slides across the platform while the print media remains stationary relative to the belt. [0003] For some stationary platforms in the prior art, in order to ensure that the printing medium passes through the printing platform smoothly and stably, a negative pressure adsorption mechanism is provided on the printing platform. For the...
