Abstract

The invention relates to the technical field of printing equipment and discloses a printing device. The printing device comprises a printing roller and a grooved wheel mechanism. The grooved wheel mechanism comprises a grooved wheel and a rotating wheel. The end face of the grooved wheel is connected with an ink guide roller, and the ink guide roller is fixed to the printing roller. The ink guideroller is provided with a plurality of ink guide grooves distributed uniformly, an ink cavity communicating with the ink guide grooves is formed in the printing roller, and the outer surface of the printing roller is provided with ink outlet holes communicating with the ink cavity. The grooved wheel is provided with a plurality of clamping grooves, the number of the clamping grooves is equal to the number of the ink guide grooves, an opening of the side portion of each clamping groove is in sliding connection with a sliding plate for sealing the opening, the sliding plates can slide in the radial direction of the grooved wheel, a cavity is formed between each sliding plate and the groove wall of the corresponding clamping groove in an enclosed mode, a piston is connected in each cavity ina sliding mode, a nozzle is connected to the end, close to the circle center of the grooved wheel, of each cavity, a pressure valve is arranged on each nozzle, and each nozzle faces the interior of the corresponding ink guide groove. The rotating wheel is provided with a clamping post. By means of the printing device, the problem that ink liquid in ink grooves is thrown out during ink feeding of existing printing rollers can be solved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a printing device. Background technique [0002] Gravure printing is a common direct printing method, which is suitable for high-speed and mass printing production. The printed finished product has the characteristics of thick color, thick ink layer, bright color, high saturation and stable quality. [0003] In the process of printing pasted advertising leaflets, it is necessary to directly immerse the lower part of the printing roller in the ink in the ink tank, and then apply the contaminated ink to the printing paper passing through the upper part of the printing roller for printing, and then Glue on the back of the printed side. In the process of dip coating and inking, since the printing roller is in contact with the ink in a large area, and the printing roller will be in a state of high-speed rotation (usually at 60-500 rpm). When the rotation speed of the prin...
