Abstract
The utility model discloses a rubber covered roller for a printing machine. The rubber covered roller comprises an internal layer cylinder and an external layer cylinder, wherein ink jet components are arranged in the internal layer cylinder; a ball bearing is arranged between the internal layer cylinder and the external layer cylinder; ink permeable holes are uniformly formed in the internal layer cylinder and the external layer cylinder; an adhesive-pressing layer with rubber particles is arranged on the external layer cylinder; and a plurality of grooves which are distributed in parallel are formed on the adhesive-pressing layer. According to the utility model, the adhesive-pressing layer is arranged on the external layer cylinder of the rubber covered roller, and the grooves are formed on the adhesive-pressing layer, so that the ink can be prevented from being deposited, particularly stacked at edges between the outer circumference and the end surfaces of the rubber covered roller, and the difficulty of manual cleaning is reduced; through the arrangement of the ink jet components, an ink transferring and guiding mechanism of the printing machine is simplified, and the equipment production difficulty and production cost of the printing machine are reduced; and the internal layer cylinder is arranged in the external layer cylinder in a bias way, so that the internal layer cylinder can touch a microswitch through a pressing bar during the rolling process, a pressure pump can pressurize the ink to be rapidly ejected, and the printing precision is increased.
Description
Technical field
The utility model relates to a kind of printing machine rubber roll, belongs to the printing equipment field.
Background technology
In offset printing process, printing ink is by ink foundation roller, wavers, a plurality of distributor rollers, inking roller, plate cylinder and blanket cylinder, supply with printing between blanket cylinder and the impression cylinder from ink fountain. the printing ink of transferring to blanket cylinder is further transferred to as stock, on the paper by printing.Blanket cylinder is applied to the desired zone of its external peripheral surface with printing ink, with the surface of printing paper to pressing, thereby the paper particle that makes paper surface with remain in the lip-deep ink adhesion of blanket cylinder together.The printing ink part that mixes with the paper particle is going up in the opposite direction with ink supply side, transfers in succession on plate cylinder, inking roller, ink transfer rod and the wavers.Therefore, the ink deposition that is mixed with the paper particle and especially be deposited on the excircle and the marginal portion between its each end face of each wavers and distributor rollers.It is outstanding and hard that the deposit of printing ink becomes gradually, thereby needed every day deposit is removed before printing operation.This work is made us feeling trouble and taking time and effort. have at printing machine under the situation of many distributor rollers, the work of removing printing ink allows the people feel to bother very much.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of printing machine rubber roll is provided, and reduced device fabrication difficulty and the production cost of printing machine, and the raising printing precision is reliable and stable, long service life.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of printing machine rubber roll, comprise internal layer tube and outer tube, and its internal layer tube inside is provided with inkjet component, is provided with ball bearing between internal layer tube and the outer tube; Be provided with the ink bleed hole on described internal layer tube and the outer tube; Described outer tube is provided with the moulding layer that has rubber grain, and the moulding layer is provided with some parallel grooves distributed.
Optimize, above-mentioned printing machine rubber roll, its inkjet component comprise a print cartridge, print cartridge one side is connected with the pressure pump housing, and the power end of the pressure pump housing is connected with microswitch, and the top of microswitch is provided with depression bar, be with spring on the depression bar, the top of spring contacts with internal layer tube inwall.
Optimize, above-mentioned printing machine rubber roll is provided with some sponge ink absorbing layer between its internal layer tube and the outer tube, and the sponge ink absorbing layer is positioned at below, ink bleed hole.
Optimize, above-mentioned printing machine rubber roll, its internal layer tube is eccentric the setting in outer tube.
Optimize, above-mentioned printing machine rubber roll, the two ends, inside of its internal layer tube are provided with roll change and revolve axle, and roll change is revolved axle and is connected with the internal layer tube by screw thread.
The outer tube of rubber roll of the present utility model is provided with the moulding layer, and the moulding layer is provided with some grooves, prevents that ink deposition from the marginal portion between the excircle that especially is deposited in rubber roll and its end face, having reduced labor cleaning's trouble; The setting of inkjet component makes the ink transfer of printing machine lead black mechanism and is simplified, and has reduced device fabrication difficulty and the production cost of printing machine; The internal layer tube is eccentric the setting in outer tube, makes the internal layer tube can touch microswitch by depression bar in rolling process, makes the compression pump body can make the printing ink supercharging, and ejection fast increases printing precision.
