Description

A kind of self-operated measuring unit of film stationary fixture and film shrink rate
Technical field
The present invention relates to thin film physics performance detection technical field, the film designed for film heat shrinkable characteristic is surveyed Device is measured, the self-operated measuring unit of a kind of film stationary fixture and film shrink rate specifically in automatic measurement technique.
Background technology
Film refers to by a variety of high molecular materials molding a kind of plastic material by technical process such as co-extrusion, stretchings, Have many advantages, such as that transparency and glossiness are high, material non-toxic, molecular structure stabilized, and have the function of completely cutting off smell and moisture. In view of this, film has been widely used in the industries such as food packaging, cigarette packaging.Film shrink rate refers to film one With the change rate of certain time inside dimension under the conditions of constant temperature degree, it is an important technology index of film characteristics.Film is heated The characteristic of contraction directly affects the beauty of product outsourcing, and percent thermal shrinkage appropriate can be such that product outsourcing has tightlier, evenly Wrapping property avoids package cover from generating fold and pack the problems such as incomplete;Heat sealability is taken into account simultaneously, to ensure that packaging has It is good to be close to effect.
Since the percent thermal shrinkage of film is to the products important such as food, cigarette, the percent thermal shrinkage of film is examined It surveys and control is an essential link in Related product production process.In general, the survey that each enterprise or testing agency use Amount means and tool differences are larger, and the uncertainty of test process is larger, so that data can between each enterprise or testing agency It is more poor than property, it is difficult to realize that film packing material quality is accurately controlled.
Existing film shrink rate test method is mainly manual measurement, and tool is Steel Ruler, and Main Basiss are countries The national standard GB/T 10003-2008 of Quality Supervision Bureau and national administration commission's joint publication《General applications Biaxially oriented polypropylene (BOPP) film》The test method, defined film shrink test method are:First uniformly cut out along thin-film width direction 100mm × 100mm square samples are taken, marks and accurately measures horizontal, film on longitudinal direction length, then put film sample It sets on being stained with the pallet of talcum powder, is put into baking oven and heats 5 minutes, taking-up measures thermal contraction after being cooled to experimental situation temperature Size afterwards calculates horizontal, longitudinal percent thermal shrinkage.It is artificial to measure that there are following main problems using Steel Ruler:1) operator Member measures film length using Steel Ruler, and human interference is big, and measurement accuracy is low;2) measurement process is complicated for operation, cannot count automatically The percent thermal shrinkage with recording sheet is calculated, efficiency is low and labor intensity is big.
Related researcher has been directed to the design of the film shrink rate measuring device with automatic detection function. In 103308548 A of patent CN《A kind of cigarette packaging film percent thermal shrinkage measurement method》In, film is cut into elongated strip, Then the heat-shrinkable of film is measured using pulling force and length variation, this measurement method is only applicable to measure elongated strip thin Film, limitation is big, and is unable to the heat-shrinkable of the vertical and horizontal of accurate response sheet film, this and YC-266《Cigarette film》 Testing standard be not consistent.In 205593949 U of patent CN《Film sheet percent thermal shrinkage is measured using optical imagery technology Device》, measured using optical imagery technology wherein describing, but film will produce fold and distortion during heating, only from Perfect condition carrys out testing film, and the case where considering film fold and distort, and film is transparent material, the patent introduction Be to put camera, film side can not be identified well in not good ray space by carrying out film graphics identification Boundary, and by method of scoring, it is not only troublesome, can also because of line thickness it is different, the depth of parallelism difference of two lines cause to measure not Accurately.Therefore, invent the self-operated measuring unit of film stationary fixture and film shrink rate a kind of to the percent thermal shrinkage of film into Row measures, and becomes film relevant enterprise key technical problem in the urgent need to address.
Invention content
The purpose of the present invention is being directed to film shrink rate measurement process, a kind of film geometrical clamp is provided The self-operated measuring unit of tool and film shrink rate.The technical problem to be solved by the present invention is to overcome film shrink rate to measure The shortcomings that, corrugation, distortion occur for shape especially after film heating, how to solve accurately to measure Film shrinkage length at this The key problem in technology of invention.The present invention practical problem of measured thin film is designed it is a kind of accurate, reliable, easily measure dress It sets, film can accurately and fast be measured by the length automatic measurement to film before and after heating using apparatus of the present invention Percent thermal shrinkage.
