Printing press paper coiling assembly, and usage method thereof

Abstract

The invention provides a printing press paper coiling assembly. The printing press paper coiling assembly comprises at least two paper coiling portions which are arranged linearly. A telescopic portion is arranged between every two adjacent paper coiling portions, is connected with both the two corresponding paper coiling portions, and can adjust the distance between the two corresponding paper coiling portions. Each paper coiling portion comprises a rotary shaft and a pretensioning portion arranged in the circumferential direction of the rotary shaft. When one pretensioning portion is sleevedwith a paper element in a connected manner, the pretensioning portion can move relative to the paper element in the direction perpendicular to the inner surface of the paper element when making elastic contact with the paper element. An abutting portion connected with one rotary shaft and the corresponding pretensioning portion is further arranged between the rotary shaft and the pretensioning portion, and can drive the pretensioning portion to move in the direction perpendicular to the inner surface of the paper element. The printing press paper coiling assembly is good in clamping stabilityand can be suitable for paper elements of various length specifications and various diameter specifications.

Description

Technical field [0001] The invention relates to the field of printing technology, in particular to a printing press roll paper assembly and a method of use thereof. Background technique [0002] In existing printing presses, paper roll components are generally required to feed and rewind paper, so that the printing paper can pass on the surface of the worktable; it is generally connected to the paper core by a paper roll and drives the paper core to rotate, thereby turning the paper feeding roll The printing paper on the upper part is sent out, and the printing paper is wound up by the take-up reel; the clamping piece is clamped from the two sides of the feed reel and the take-up reel when the paper is rolled. It has the following technical problems: [0003] 1. The above-mentioned clips have poor stability when clamping the paper core, which may easily cause the paper core to deviate and the roll paper stability is not ideal. [0004] 2. The above-mentioned paper roll assembly can...

AI Technical Summary

Problems solved by technology

[0003] 1. The stability of the above-mentioned clips clamping the paper core is poor, which easily leads to the deviation of the paper core, and the stability of the roll paper is not ideal

[0004] 2. The above-mentioned reel assembly can only be installed with paper cores of specified diameters and lengths. If paper cores with different diameters or lengths are to be rewound, it is necessary to replace the reel roll or add an auxiliary sleeve of the corresponding specification, which is inconvenient to use. , and the scope of application is small
