A kind of colour fastness to rubbing instrument
The utility model relates to a kind of quality detection apparatus, specifically a kind of colour fastness to rubbing instrument.
It has been a mandatory examination criteria of country that the colour fastness to rubbing of textile detects, existing colour fasteness to rubbing instrument, the output shaft that is power source is connected with the actuating arm of four-bar mechanism, four-bar mechanism is provided with friction head, the specimen holder that is provided with on the platform, friction head does to come to-and-fro movement on specimen holder, by textiles different in the specimen holder is carried out reciprocating type friction, to check by the colour fastness of test agent under drying or wet environment.Because China is different with the operative norm that the fastness to rubbing of the main developed country in west detects, this is mainly reflected in the to-and-fro movement stroke of friction head, and different standards needs different instruments to carry out, so, just necessary replacement equipment had both increased expenditure, had also reduced plant factor.
Summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of colour fastness to rubbing instrument reasonable in design, simple in structure is provided.
The technical scheme that its technical matters that solves the utility model adopts is: comprise platform, power source and four-bar mechanism, four-bar mechanism and power source are separately positioned on the platform, power source is connected with the actuating arm of four-bar mechanism, described actuating arm middle part is provided with microscler through hole, actuating arm is connected together by the output shaft of locking button and power source, is that microscler through hole one side is provided with scale on the described actuating arm.
Four-bar mechanism is provided with friction head.
Platform is provided with controller.
When power source moves, drive the actuating arm motion, thereby drive the four-bar mechanism running.Fastness to rubbing for different operative norms detects, only need to regulate the locking button, regulate the position of output shaft in microscler through hole of power source, and can calculate the stroke of friction head on specimen holder accurately, and then be fixed by the locking button and get final product by scale.
A kind of colour fastness to rubbing instrument of the present utility model compared with prior art, the beneficial effect that is produced is:
1, avoided many various criterion colour fastness pick-up units repeat purchase, reduced the detection cost, improved usage ratio of equipment, help carrying out smoothly of quality supervision technical service work.
2, have characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, thereby have excellent popularization and use prospect.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, power source, 2, actuating arm, 3, microscler through hole, 4, the locking button, 5, scale, 6, four-bar mechanism, 7, controller, 9, friction head.
Below in conjunction with accompanying drawing the utility model is done following detailed description the in detail.
As shown in drawings, a kind of colour fastness to rubbing instrument of the present utility model, its structure comprises platform 8, power source 1 and four-bar mechanism 6, four-bar mechanism 6 is separately positioned on the platform 8 with power source 1, power source 1 is connected with the actuating arm 2 of four-bar mechanism 6, described actuating arm 2 middle parts are provided with microscler through hole 3, and actuating arm 2 is connected together by the output shaft of locking button 4 with power source 1, is that microscler through hole 3 one sides are provided with scale 5 on the described actuating arm 2.
Four-bar mechanism 6 is provided with friction head 9.
Platform 8 is provided with controller 7.
A kind of its processing and fabricating of colour fastness to rubbing instrument of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be those skilled in the art's known technology.
