A kind of thin material thickness detection apparatus
The utility model belongs to online measuring technique field, more particularly, to a kind of thin material thickness detection apparatus.
In thin material production, in order to ensure product quality, its thickness and weight have strict demand.By taking plaster as an example,
Ointment weight in plaster unit area must be controlled within certain limit, can neither it is too low can not be too high --- when too low
Drug effect is not had, product becomes substandard products, and this plaster is the irresponsibility healthy to consumer into market；When too high then
The cost of manufacture of manufacturer is increased, and causes the waste to raw material.
Therefore, meet the requirements to ensure plaster product, plaster producer generally controls cream using the method manually weighed
Medicine paste containing amount, specific practice is：The medicated plaster cloth after cream is applied after drying machine drying, in medicated plaster cloth various location, work people
Member cuts out normal size plaster, and weighs out every plaster weight in the balance, and then deducting and weigh, plaster is equirotal mounts
Back of the body weight, you can obtain every plaster and apply ointment weight.Staff is by by various location ointment weight and standard ointment
Weight is contrasted, then plaster coating machine is adjusted, to control thickness of covering of the plaster coating machine to medicated plaster cloth, so as to control plaster
But during this method cutting plaster, need to suspend plaster coating machine, therefore sampling observation plaster of manually weighing can not excessively frequently
It is numerous, can otherwise affect whole production efficiency.Typically after coating 50～100m of production, can inspect by random samples once.If by this way
Produced, under extreme case, can cause the plaster of 50～100m all becomes waste product, artificial and raw material can all cause wave
Take, this can cause extreme influence to the performance of enterprises.
Patent《Full-automatic rubber paste coating equipment and technique》In (application number 200810028987.2), utility model
People proposes the technology of thickness measurement online, using gamma ray, in plaster face high speed shuttle-scanning, detects the thickness of plaster, and will
Real-time detection value is compared with pre-set value, and comparative result feeds back to control system, and control system adjusts again scraper gap, makes
Plaster applied thickness reaches preset value.The method real-time of this on-line checking is higher, does not contact with plaster during measurement, will not be right
Product cause damage, but detect precision it is inadequate.Because typically in 0.1～0.2mm, thickness error control exists plaster thickness
Within 10%, i.e., accuracy of detection will reach 10 μm, for this thickness measurement technology using reflection or transmission principle, detection essence
Degree is unable to reach production requirement.In addition, gamma ray radiation also can cause great threat to operator's health.
Traditional non-online test method, efficiency is low and low-response；And online test method, precision is unable to reach again will
Ask.Therefore, study a kind of response soon and accuracy of detection is high, and do not affect the testing equipment of production efficiency that there is great meaning.
