The invention discloses a printing rack with a good adsorption function, and belongs to the technical field of printing equipment. The printing rack comprises a rack body and a vacuum pump; a group of sucking slots which are distributed at equal space is formed in the table board of the rack; a printing base plate which is matched with the sucking slots in an inserting mode is arranged above the rack; the vacuum pump is fixedly arranged on the bottom of the rack, and communicates with the sucking slots through an air sucking path positioned inside the rack; and paper pressing devices are symmetrically arranged at the two sides of the upper surface of the rack. According to the printing rack disclosed by the invention, the vacuum pump is matched with the sucking slots, so that the paper can completely spread on the printing gasket, and therefore, wrapping and folding phenomena are avoided and printing quality is guaranteed; and the printing rack is matched with the paper pressing devices, so that fixing of paper is further guaranteed. Meanwhile, the printing rack further has the characteristics of a simple structure, a reasonable design, low purchasing cost, and the like.
Description
technical field [0001] The invention relates to the technical field of printing equipment, in particular to a printing stand with good adsorption function. Background technique [0002] In the printing process of printing products, because the paper is thick and fluffy, it is necessary to adjust the compression of paper of different thicknesses to a reasonable degree, and the tightness of the compression can be adjusted at any time to achieve a satisfactory printing effect. . Existing compression devices usually use cylinders as the compression power. Because the cylinders move quickly, they can quickly compress the paper. However, excessive compression of the paper will cause inconvenience to the movement of the paper during printing. Therefore, it is often necessary to adjust frequently for different thicknesses of paper. The working stroke of the cylinder causes cumbersome operation and affects work efficiency; at the same time, the traditional paper pressing device will...
