A kind of automotive trim color fastness tester
Technical field
The utility model belongs to automobile technical field, relates to a kind of color fastness tester, particularly a kind of automotive trim color fastness tester.
Background technology
Colorfastness to rubbing is meant dyed fabric in use or process, and the degree of fading under rubbing action is an important indicator of fabric.Colour fastness is good and poor, directly relate to the healthy and safe of human body, the product of colour fastness difference is in wearing process, running into rainwater, sweat will cause pigment on the lining to come off to fade, then wherein the molecule of dyestuff and heavy metal ion etc. all might be absorbed by the body and the health of harmful to human skin by skin, also can influence other clothes of being through on one's body on the other hand by staining, dye dirty other clothings during perhaps with other clothes washings.
The test of fabric colour fastness is conventional sense project in the test of fabric inherent quality, evaluates the fastness grade according to the variable color of fabric and the staining of the adjacent fabric that is unstained.Because of fabric suffered condition difference in processing and use is very big, require to have nothing in common with each other, so existing test method major part all is to carry out simulation test or compbined test by the environment and the condition that act on.Colorfastness to rubbing test generally is divided into unlubricated friction and wetly rubs two kinds, respectively at the colour fastness of test samples under dry and wet environment.
Fabric and leather use more frequent in automobile, and interior material in the car and seat webbing etc. all use fabric and leather mostly.And fabric and leather are because of production technology different with material, its firm coloration degree is also inequality, fabric that colour fastness is good and leather use on automobile, can give and drive or the motroist builds an environment by bus that safety and environmental protection is comfortable, environment also can impact the car load brand otherwise not only reduce by bus.The structure of colorfastness to rubbing detector in the market is more complicated all, cost cost height, and the scope of application is little, makes the detection of automotive trim colour fastness be difficult to popularize.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed the strong automotive trim color fastness tester of a kind of applicability.
The purpose of this utility model can realize by following technical proposal: a kind of automotive trim color fastness tester, comprise frame, driving mechanism and one are in the stand that upper rack is used for installing along horizontal direction automotive trim, it is characterized in that, described frame is provided with crankshaft arrangement, described crankshaft arrangement drives by described driving mechanism, be provided with friction head directly over the described stand, but be provided with the connecting rod that an along continuous straight runs slides between described friction head and the described crankshaft arrangement, described connecting rod can make described friction head along continuous straight runs reciprocating under the drive of crankshaft arrangement.
Be the colour fastness of control and detection automotive trim, this test instrument can be used in the automotive trim sample friction when the simulation occupant takes on the test instrument, with the colour fastness of testing automobile interior trim, during test sample is installed stand and can carry out test.Driven crankshaft arrangement and made connecting rod do the horizontal direction to-and-fro movement by driving mechanism, an end of connecting rod is connected with friction head, and friction head is along with rub back and forth sample on the stand of the motion of connecting rod, thereby reaches the rub effect of automotive trim of simulation occupant.
In above-mentioned automotive trim color fastness tester, described driving mechanism is a motor, and described motor is fixed on the described frame.The rotating shaft of motor is connected with crankshaft arrangement, the operation of rotating shaft rotating band dynamic crankshaft device.
In above-mentioned automotive trim color fastness tester, described crankshaft arrangement comprises support and the crankshaft disk of being located on the support, the central shaft of described crankshaft disk is connected mutually with the rotating shaft of described motor, and described crankshaft disk is provided with a bent axle, and this bent axle is connected with described connecting rod.The rotating shaft of motor drives the central shaft rotation of crankshaft disk, also and then rotation of crankshaft disk simultaneously, and the bent axle on the crankshaft disk rotates around central shaft.Utilize the rotation skew principle of bent axle on crankshaft disk to be converted into straight reciprocating motion, be used for the drivening rod to-and-fro movement, reach sample and the friction head purpose of mutual friction mutually on the stand with this.
In above-mentioned automotive trim color fastness tester, described stand comprises a horizontally disposed backing plate and is positioned at the depression bar of backing plate both sides that described depression bar is mobilizable to be pressed on the backing plate.Backing plate can hold sample tilings such as fabric or leather and come, and the depression bar of backing plate both sides is movable structure, can be close to mutually with backing plate; After completing sample, mobile depression bar is pushed down sample and be fixed on the backing plate, when friction head and sample friction, prevents that friction force from making sample break away from backing plate.
In above-mentioned automotive trim color fastness tester, also be provided with a water treatment plant on the described frame.Sample wet rub the test after, the moisture in the sample need be removed so that detect.Drain moisture in the wet sample that rubs by water treatment plant, check, thereby evaluate and test out the colour fastness of sample through the wet sample that rubs behind the drainage.
In above-mentioned automotive trim color fastness tester, described water treatment plant comprises two tangent last cylinder and the bottom rolls that are arranged on the frame, and described upward cylinder is to be connected with the rotating shaft of described motor by belt.Wet when rubbing test, the wet sample that rubs is with after friction head is finished mutual friction mutually, starter motor, the rotating shaft of motor drives by belt and goes up the cylinder rotation, the sample that rubs of will wetting is placed between cylinder and the bottom roll, the last cylinder of rotation cooperates with tangent bottom roll is being with the wet sample that rubs to extrude between two cylinders, thereby reaches the effect that drains the wet sample moisture that rubs.
Compared with prior art, this automotive trim color fastness tester is converted into straight reciprocating motion by the rotation skew principle of crankshaft disk, it is reciprocating to be used for drivening rod, thereby reaches friction head and the sample purpose of mutual friction mutually, makes the simple in structure and low cost of manufacture of this test instrument; And this test instrument is applicable to unlubricated friction and the wet two kinds of patterns of rubbing simultaneously, applied widely.
