Problems solved by technology

In addition, while the clamping mechanism is swinging, it will also move along its own axis, and the lateral force generated by the friction between the positioning ring and the bracket, as well as between the clamping mechanism and the two slide grooves, will seriously interfere Load cell to obtain real writing friction data

Abstract

The invention provides a ball pen writing lubrication detector and a detecting method thereof. The ball pen writing lubrication detector comprises a clamping mechanism used for clamping a sample cartridge, a clamping mechanism support with an adjustable writing angle, a linear motion mechanism, a rotating platform, a control system and a computer, wherein the clamping mechanism is arranged in the clamping mechanism support, a tension sensor is arranged at the lower portion of the clamping mechanism support and used for collecting detection data of the sample cartridge, the linear motion mechanism is connected with the clamping mechanism support and used for driving the clamping mechanism support to move linearly and drive the sample cartridge to rotate, the rotating platform is used for placing writing paper and can enable the writing paper to rotate, the control system is in control connection with the linear motion mechanism and the rotating platform and used for adjusting the linear motion speed of the linear motion mechanism and the rotating speed of the rotating platform, and the computer is connected with the tension sensor and used for processing and collecting the detection data to obtain detection results. The ball pen writing lubrication detector and the detecting method thereof can scientifically and reasonably represent the writing lubrication of a ball pen.

Description

technical field [0001] The invention relates to a detection method of a writing pen, in particular to a ballpoint pen writing lubricity detector and a detection method thereof. Background technique [0002] What people feel when writing is the writing comfort. The so-called writing comfort refers to the comprehensive reflection of fluency and lubricity when writing. The fluency of writing can be determined under the specified writing angle, writing speed and writing pressure. , using a special writing instrument to quantitatively determine the fluency of writing by detecting the condition of the writing lines, the amount of ink output and its fluctuations; Quantitative detection methods can only rely on experienced people to make qualitative judgments through comparison methods. [0003] CN201819762U discloses a writing tool friction tester, which can more accurately detect the friction of various pens when writing through the scribing mode of linear motion. Considering th...
