Life evaluation tester for paper feed roller of printer or copier

Abstract

The invention relates to a life evaluation tester for a paper feed roller of a printer or copier, and the tester comprises a base, a positioning device, an evaluation test paper, a conveying device and a driving device, wherein the evaluation test paper is transferred between the paper feed roller and a first conveying roller to a second conveying roller. The life evaluation tester provided by theinvention carries out paper feed test by simulating the paper feed roller in combination with the set time and rotation speed information under the real use condition, the user can determine whetherthe service life of the paper feed roller meets the requirements by self measuring the thickness change of the paper feed roller before and after the experiment, and only one paper feed roller is evaluated at a time, so that there is basically no interference during the evaluation process, problems are easy to find, and the data collection is convenient and accurate.

Description

technical field [0001] The invention belongs to the field of life detection of rubber rollers, and in particular relates to a life evaluation tester for paper feeding rubber rollers of printers or copiers. Background technique [0002] As we all know, the paper feeding rubber roller is a key functional component of the printer / copier. It mainly realizes the transmission of the paper through the friction formed between the rubber roller and the paper, so as to complete the purpose of printing or copying. [0003] At present, the performance evaluation of rubber rollers can only be based on basic physical and static performance parameters (such as hardness, friction coefficient, tensile strength, tear strength, elongation at break, rebound performance, flex performance, surface roughness, compression, etc.) permanent deformation, dimensional and tolerance accuracy, weatherability, etc.). However, both dynamic parameters and durability performance can only rely on the customer...

Problems solved by technology

[0003] At present, the performance evaluation of rubber rollers can only be based on basic physical and static performance parameters (such as hardness, friction coefficient, tensile strength, tear strength, elongation at break, rebound performance, flex performance, surface roughness, compression, etc.) permanent deformation, dimensional and tolerance accuracy, weather resistance, etc.)

However, both dynamic parameters and durability performance can only rely on the customer’s actual machine evaluation, and then feedback the evaluation results to the manufacturer to adjust the material and process parameters. Therefore, the feedback information has a long lag, which is very unfavorable for delivery. The material and process of the paper rubber roller are adjusted
