Problems solved by technology

The quality inspection of paper products is mainly the detection of geometric dimensions such as diameter, height, and taper. At present, paper cups, paper bowls and other paper products are mostly measured by direct or indirect methods such as vernier calipers and height gauges. Contact measurement methods are easy to cause Paper products are deformed, the measurement results are inaccurate and inefficient, especially the automation of the measurement process and data processing cannot be realized, which is far from meeting the needs of modern economic and technological development

Abstract

The invention relates to a non-touch measuring device for the geometry size and tolerance of the paper cup. The feature is that it includes geometry aiming-driving unit, and location detecting and signal collecting processing unit. The geometry aiming-driving unit includes X-Y work platform device, rotating work platform device, X-Y flexible jiggle platform device, Z direction lifting work platform device A that realizes Z shaft direction lifting and Z direction lifting work platform device B that realizes Z shaft direction and horizontal direction adjusting. The location detecting and signal collecting processing unit includes a first laser location sensitive sensor, two second laser location sensitive sensor, two transmission grating rule, closed control circuit formed by measuring and feedback height signal process circuit and step motor server driving signal, diameter signal process circuit, grating process circuit. The invention has advantages of high accuracy, high efficiency, automatic measuring process and data process.

Description

technical field [0001] The paper cup measuring instrument of the invention mainly relates to a non-contact measuring instrument for measuring the geometric dimensions and tolerances of paper cups. Background technique [0002] The development of today's tourism industry has greatly promoted the demand for paper products such as paper cups and paper bowls. The market demand for paper products has stimulated the development of the paper product manufacturing industry. Qi, leading to low product quality and sometimes endangering the legitimate rights and interests of consumers, strengthening the quality inspection of paper cups, paper bowls and other paper products has become a top priority. The quality inspection of paper products is mainly the detection of geometric dimensions such as diameter, height, and taper. At present, the measurement of paper products such as paper cups and paper bowls mostly uses direct or indirect methods such as vernier calipers and height gauges fo...
