Description

Technical Field

[0001] The utility model relates to the technical field of printing mechanisms, in particular to a printing mechanism of a printing press. Background Art

[0002] A machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding).

[0003] The printing mechanism is the main functional structure of the printing machine. The existing public patent (publication number is CN 210415895 U) discloses a printing mechanism of the printing machine, including a base, a transmission mechanism, and a printing component. The transmission mechanism is a crawler transmission mechanism. Paper is placed on the surface of the transmission mechanism. The two end surfaces of the rear side of the base are fixedly connected with mounting seats. A square block is installed in the square groove of the mounting seat. The inner end surface of the square block is fixedly connected with a round rod. The outer surface of the round rod is fixedly connected with a curved pressing plate. The outer surface of the curved pressing plate is provided with a notch. The lower surface of the curved pressing plate contacts the upper surface of the paper. The square block is snapped into the square groove of the mounting seat. The inner end surface of the rear side of the mounting seat is slidably connected with a bayonet pin and a spring through a slide groove. The paper pressing mechanism is fixed by adopting a snap-fit ​​structure, which can be quickly positioned and fixed without displacement or sliding. It is more firm and convenient for the ink to dry after paper printing.

[0004] The above-mentioned positioning of paper to facilitate subsequent air drying is essentially the same as the traditional printing air drying method. The air drying of ink still requires a certain amount of time, resulting in the need to set up an additional drying structure for the air drying of the printed ink. The practicality is low and has certain limitations in actual use. Therefore, the utility model proposes a printing mechanism of a printing press to achieve improvements on the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a printing mechanism of a printing machine to solve the problem in the above background technology that the existing printing structure has a single function and lacks a structure for accelerating the drying of ink on the surface of the printed product, resulting in the need to set up a separate storage structure for the drying of the ink after printing is completed.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a printing mechanism of a printing press, comprising a support leg, a bracket fixed to the upper end of the support leg, a preheating treatment component fixed to the upper side of the bracket, and an air blowing component fixed to the lower part of the support leg; the preheating treatment component comprises a grille fixed to the upper side of the bracket, a top plate fixed to the upper side of the grille frame, a heating chamber arranged in the middle position of the top plate, and a fan 1 arranged on the upper side edge of the top plate; the air blowing component comprises a mounting plate fixed to the lower inner part of the front support leg, and a fan 2 fixed to the middle position of the inner side of the mounting plate.

[0007] Preferably, a mounting frame is fixed to the outer side of the supporting leg located at the front, a supporting rod is fixed to the horizontal end of the mounting frame, and a printing head is fixed to the supporting rod via a tightening knob.

[0008] Preferably, a front roller is movably provided at the middle position of the supporting leg located at the front, and the front roller cooperates with the printing roller inside the printing head.

[0009] Preferably, a rear roller is movably provided at the middle position of the supporting leg located at the rear, and a transmission roller is provided inside the bracket.

[0010] Preferably, the side surfaces of the grille frame are hollowed out.

[0011] Preferably, the air outlet of the fan 1 is communicated with the interior of the heating chamber, and the air outlet of the heating chamber cooperates with the middle opening of the top plate.

[0012] Preferably, the middle position of the mounting plate is a hollow position, and the hollow position is communicated with the air outlet of the second fan.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model heats the surface of the printed product that is about to enter the printing process by arranging a preheating treatment component, so that the ink can be dried faster during printing, and at the same time, an air blowing component is arranged to blow air to the printed product after printing, which is also used to accelerate the drying of the ink, so that after printing is completed, the printed product can be directly collected and transported, eliminating the traditional drying step, improving the printing efficiency, and having high practical value;

[0015] Specifically, during the printing process, the preheating treatment component and the blowing component are started in advance, and a heating resistance wire is provided in the heating chamber. The temperature of the wind blown by the fan 1 rises after contacting the heating resistance wire. After the hot air contacts the printed product, the surface of the printed product is heated. After the preheated printed product contacts the ink on the surface of the printing roller, the absorption effect is better and the drying is faster. After printing is completed, the printed product is blown by the fan 2 again, so that the printed product can be dried in a short time after printing is completed. BRIEF DESCRIPTION OF THE DRAWINGS
