Description
Technical field
The present invention relates to the used checkout equipment of tobacco production industry; Specifically be that stationary installation use in the special-purpose air permeability flow dish calibrating that grows tobacco, fixing during the special-purpose paper permeability flow of all size model tobacco dish standard component calibrating of the different brands in can be used for using at present in the industry.
?
Background technology
At tobacco business; Air permeability is the important physical indexs of cigarettes such as cigarette paper, shaping paper and tipping paper with paper, and each Yan Chang and cigarette are all measured the air permeability of materials such as cigarette paper, shaping paper, tipping paper at the various model air permeability tester for papers that use different brands with paper enterprise.
The relevant criterion of air permeability measuring method mainly contains tobacco business standard YC/T 172-2002 " cigarette paper; Shaping paper; Tipping paper and have the mensuration of the material air permeability of directed air permeable belt "; Standard GB/T 23227-2008 " cigarette paper; Shaping paper; Tipping paper and have the mensuration of the material air permeability of directed air permeable belt " and international standard ISO 2965-2009 " cigarette paper; Shaping paper; Tipping paper; Has the dispersion or the material of fixed ventilation band and mensuration " with material air permeability of different air permeability stripeds.Each model air permeability tester for paper of different brands all be with reference to the technical requirement that proposes in these standards design and develop.The principle of work of these air permeability tester for papers all is that the pressure reduction that utilizes gas stream when restriction device, to be produced is measured flow, and shows the air permeability value of paper according to this flow.
Air permeability flow dish is a kind of gas flow standard spare that is used for the calibration sheet densometer, thereby passes to cigarette guarantees densometer with air permeability tester for paper measurement accuracy through the value with air permeability flow dish.The accuracy of air permeability flow dish transmission value then need realize through the calibrating to air permeability flow dish.
Because the type of the air permeability tester for paper that uses at present is a lot; Manufacturer is different; Age is different, and model is different, thereby causes calibration supporting on the various air permeability tester for papers all to have nothing in common with each other with the geomery size of air permeability flow dish; This just causes when examining and determine different air permeability flow dishes has to adopt the special fixing device of customization to be fixed, and makes the calibration operation of flow dish very inconvenient.
?
Summary of the invention
The object of the invention just is being based on the prior art situation and stationary installation is used in the custom-designed one special-purpose air permeability flow dish calibrating that grows tobacco; Utilize this device can air permeability flow dish be fixed and, rubber seal sealing tight with the elbow cramping; Different flow standard spares only need change locating piece or down in the locating piece corresponding accessory get final product; And open the elbow folder, locating piece on the flow dish is opened around the upset of upset pivot pin just can be changed the dissimilar air permeability flow dish of different manufacturers fast.
The object of the invention can be realized through following technique measures:
Stationary installation is used in the calibrating of the special-purpose air permeability flow of tobacco dish; Comprise the top base and the bottom base that are separately fixed on the frame; The last locating piece that is provided with central through hole is connected on the top base, and can be around the upwards upset of upset pivot pin, and the following locating piece that is provided with central through hole is installed on the bottom base; And this time locating piece upper surface offers cylindrical heavy chamber; Can place flow dish to be tested between the upper and lower locating piece, on the sidewall of upper and lower locating piece, all offer the pressure survey mouth that is communicated with corresponding locating piece central through hole, mating surface is equipped with O-ring seal on the following mating surface of last locating piece and following locating piece.
On top base, be symmetrically arranged with two manual elbow folders that are used for pressing down locating piece.
Last locating piece is connected with top base through a connection piece, and last locating piece is fixed on the web member, and this web member is connected in top base through the upset bearing pin.During use, last locating piece together upwards overturns around bearing pin with web member.
Can place the flow dish to be tested of all size between the upper and lower locating piece.
Utilize apparatus of the present invention when calibrating flow dish; At first the flow dish is placed on down in the locating piece; Then locating piece on the flow dish is overturn around the upset pivot pin; Utilize elbow folder that the flow dish is pressed under the flow dish on the locating piece and flow dish between the locating piece, use the rubber seal sealing between flow dish and the locating piece.The special-purpose air permeability flow dish of multiple tobacco can use with a kind of stationary installation, and different flow dishes only need be changed the corresponding accessory that uses in locating piece or the following locating piece of going up and get final product, and need not to change or remove whole device.
The present invention compares prior art and has following advantage:
1, can fix the air permeability flow dish of different model and specification;
Fix and change air permeability flow dish when 2, conveniently examining and determine;
3, can upgrade through increasing suitable accessory to the air permeability flow dish of follow-up newly-increased type.
