Printing roller bearing self-lubricating device for paper processing

Abstract

The invention relates to the technical field of papermaking, and discloses a printing roller bearing self-lubricating device for paper processing. The device comprises a bearing body, a connecting shaft is fixedly connected to an inner cavity of the bearing body, telescopic columns are uniformly arranged in front of a bearing body at the periphery of the connecting shaft, and an extrusion head isfixedly connected to one end, far away from the connecting shaft, of each telescopic column. A negative suction cylinder is fixedly connected to the upper portion of the bearing body, and a piston rodis slidably connected to the interior of the negative suction cylinder. According to the printing roller bearing self-lubricating device for paper processing, the telescopic columns are driven by theconnecting shaft to extend under the influence of centrifugal force to intermittently extrude the piston rod, the negative suction cylinder sucks in oil in an oil storage tank through air pressure, then the oil is discharged into the bearing body through an oil spraying pipe when the piston rod returns, air is generated through an extrusion bag, and the gas is pressurized through a blocking block, so that the burden of manual oil adding lubrication is effectively reduced, and the lubricating effect on the bearing body is effectively improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a printing cylinder bearing self-lubricating device used for paper processing. Background technique [0002] At present, after the corresponding papermaking enterprises process the raw materials into paper products, they need to print the corresponding text or pattern logo on the paper. This process requires the use of a printing machine, and the printing accuracy of the corresponding printing machine is determined by the printing cylinder bearing. When the lubricating oil in the bearing roller bearing is sufficient, its transmission will be smooth without jamming. However, during the use of general printing roller bearings for paper processing, it is necessary to use an oiler to manually adjust the oil according to the number of times of use.

Problems solved by technology

[0002] At present, after the corresponding papermaking enterprises process the raw materials into paper products, they need to print the corresponding text or pattern logo on the paper. This process requires the use of a printing machine, and the printing accuracy of the corresponding printing machine is determined by the printing cylinder bearing. When the lubricating oil in the bearing roller bearing is sufficient, its transmission will be smooth without jamming. However, during the use of general printing roller bearings for paper processing, it is necessary to use an oiler to manually adjust the oil according to the number of times of use. Adding lubricating oil, this method cannot effectively control the amount of oil added, and the timing of adding oil, it is easy to increase the burden of labor, and the lubricating oil added in this way is difficult to quickly infiltrate every part of the bearing body, making it difficult for The lubrication effect of the bearing body is not good

[0003] Aiming at the deficiencies of the prior art, the present invention provides a printing cylinder bearing self-lubricating device for paper processing, which has the advantages of effectively reducing the burden of manual lubrication and effectively improving the lubrication effect on the bearing body. , which solves the problem that during the use of general printing cylinder bearings for paper processing, it is necessary to manually add lubricating oil according to the number of uses, and the infiltration speed of the bearing as a whole is slow after the lubricating oil is added
