[0003] Among them, the pricking roller 1 is a specially made transmission roller with tiny sharp thorns. It has a large friction force under the pressure of the pressure wheel 2, which can drive the printing medium 3 to move on the printing platform 4. Under the action of the adsorption fan 5, a negative pressure is formed in the inner cavity of the printing platform 4, so that the printing medium 3 is adsorbed on the top surface of the printing platform 4 through the adsorption hole 7, and then the printing medium 3 is printed using the printing carriage 6.

[0004] This type of inkjet printer has the following disadvantages when it comes to adsorbing the printing platform:

[0005] 1. The width of the printing media is different, and the uncovered adsorption holes will affect the adsorption force.

[0006] 2. The adsorption force required for different printing media should be adjusted based on experience. If the adsorption force of softer media is greater, the media will bulge.

[0007] 3. The media is unevenly adsorbed on the platform surface, and the printing media may wrinkle and deviate. Utility Model Content
