Technical Field

The utility model relates to the technical field of printers, in particular to a paper storage structure of a printer.

Background

The traditional paper storage and paper feeding structure for the printer is a paper winding roller for winding printing paper, so that after the paper wound and stored by the paper winding roller on the bracket is used up, printing is stopped, the paper winding roller is taken down from the bracket, a new paper storage roller is placed on the bracket, the disassembly time is increased in the process, and the printing efficiency of the printer is reduced; meanwhile, the existing paper storage structure of the printer only has two paper winding rollers for storing paper and a second paper winding roller to replace the first paper winding roller, so that the operation process is complicated and time-consuming, and the problem of reducing the printing efficiency still exists.

The prior Chinese patent (publication No. CN 217350017U) discloses a paper storage structure of a printing machine, which comprises a steel plate and a paper winding roller, wherein a rotatable bottom plate is arranged above the steel plate, at least two groups of brackets are arranged on the top surface of the bottom plate, shaft holes are arranged on the brackets, rotating shafts are arranged at two ends of the paper winding roller, the rotating shafts at two ends of the paper winding roller are inserted into the shaft holes of the brackets at two sides, the paper winding roller is rotationally connected to the brackets, a notch is arranged at the top of the brackets, a lifting table capable of lifting is arranged on the steel plate, the lifting table comprises an outer sleeve rotationally connected with the steel plate, an inner tube and a cross beam which are inserted into the outer sleeve, a hydraulic cylinder is fixed in the inner tube, a piston rod of the hydraulic cylinder is connected with the inner bottom of the outer sleeve, the outer sleeve is provided with a lateral opening, the inner tube extends out of the opening and is fixedly connected with the cross beam at the outer side of the outer sleeve, two forks are arranged on the cross beam and can move forward and backward in the horizontal direction, and are parallel to each other, and can move to the lower parts of the rotating shafts at two ends of the paper winding roller and are driven by the inner tube to lift the paper winding roller upwards from the brackets.

When the paper storage structure of the printer is used, when one group of brackets support the paper winding rollers, the paper winding rollers convey paper to the printing equipment, the unused paper winding rollers are placed above the other group of brackets for storing the paper, and after the paper on one paper winding roller is used up, the bottom plate is rotated to enable the unused paper winding rollers to rotate to a paper conveying position, and the paper on the unused paper winding rollers is butted to the printing equipment for printing; there are thus problems in that the operation of replacing the first roll with only two rolls for storing paper and the second roll is cumbersome and time-consuming and still reduces the printing efficiency.

Therefore, we propose a road construction dust device to solve the above problems.
