Abstract

The utility model relates to a leather testing device, in particular to the leather testing device used for testing the flex fatigue performance of the coating layer of coating leather. The leather testing device is provided with a tension exerting mechanism, the tension exerting mechanism exerts the continuous constant tension or the constant tension being synchronous with a tortuous cycle on a test sample in the sample testing process, making the testing process further close to flex practical situation in the use, thus ensuring that the testing result is consistent with the product practical situation, and overcoming the deficiency that an existing instrument detects the product to be difficult to reflect out the actual performance of a product.

Description

The Leather testing device

The utility model relates to a kind of Leather testing device, especially for the Leather testing device of the flexing fatigue performance test that is coated with the dressing leather coatings.

Existing flexing fatigue check meter, be under normal temperature or the low-temperature condition with sample freedom (not applying tension force) clamping after, the simple flexing fatigue check of carrying out, the index of test is that the number of times of subduing when fatigue occurring with sample is determined, detect qualified leather series products in this way, in use, when subduing number of times well below test flexing fatigue detection index, its coatings crackle just appears, breach, peel off, flexing fatigue destruction such as come off, bring very big loss for manufacturing enterprise and consumer, the reason that above-mentioned quality problems occur is: subduing during the leather series products uses, not a kind of simple subduing, it is to have subduing under certain tension force effect, this tension force is subdued the fatigure failure effect of effect to the leather class, be far longer than the endurance destruction of scratching merely, thereby be difficult to reflect that with above-mentioned instrument detecting product the actual performance of product guarantees product quality the leather class.

The purpose of this utility model is that prior art is not enough to provide a kind of actual conditions that can reflect test product truly in order to overcome, and can guarantee the Leather testing device that test result is consistent with the product actual conditions.

The purpose of this utility model is achieved in that the Leather testing device comprises sample clamping mechanism, crippling mechanism, motor and gear train, it is characterized in that described Leather testing device also is provided with tension-applying mechanism, this tension-applying mechanism in the sample testing process, apply continuous to sample or with the constant-tension of tortuous cycle synchronisation.

Adopt the Leather testing device of said structure, in the sample testing process, sample has been applied constant tension force, subdue actual conditions in the more approaching use, thereby test result is more consistent with the product actual conditions.

The utility model is described in further detail and provide embodiment below in conjunction with accompanying drawing.

Fig. 1 is the utility model example structure front view;

Fig. 2 is the utility model example structure side view;

As shown in Figure 2, the Leather testing device is provided with one group of initiatively two groups of servo-actuated clamper of clamper, rotating shaft and tension applying apparatus, can test two samples simultaneously, vertical fixing is provided with three groups of parallel slide bars on housing, every group of slide bar has two, middle groups is an active slide bar 9, front and back are with moving slide-bar 11a for two groups, 11b, with moving slide-bar 11a, 11b is higher than active slide bar 9 and the upper end is fixed on the same fixed support 10, initiatively be provided with active sliding block 3 movingly on the slide bar 9, active sliding block 3 belows and connecting rod 2 strands connect, connecting rod 2 other ends are connected driving active sliding block 3 and move up and down along main slide bar 9 with crankwheel 1, with moving slide-bar 11a, have movingly on the 11b with movable slider 7a, 7b, active sliding block 3 and with movable slider 7a, be fixed with main clamping head and servo-actuated clamping head on the 7b respectively, active clamper 4 and servo-actuated clamper, main clamping head by main clamping head by handwheel 12, handwheel screw 13, pressing plate 4 and support 14 constitute, support 14 is made of the rectangular tube that a bit of cross section is " mouth " shape, pressing plate 4 levels are placed in one, the plane is provided with screw and cooperates with handwheel screw 13 on the support 14, handwheel screw 13 passes screw and connects the formation interlock with pressing plate 4, two servo-actuated clamping head structures are with initiatively clamping head is identical, two servo-actuated clamping heads are respectively by handwheel 17a, 17b, handwheel screw 18a, 18b, pressing plate 19a, 19b and support 20a, 20b constitutes, two servo-actuated clamping heads are fixedly connected on respectively with movable slider 7a, on the 7b, slided up and down along slide bar 11a by sample 21a traction with movable slider 7a, be provided with screw 16a with movable slider 7a, hang counterweight 8a on the screw 15a after screw 16a is fixedly connected on movable slider 7a below and constitute tension-applying mechanism; Slided up and down along slide bar 11b by sample 21b traction with movable slider 7b, be provided with screw 16b with movable slider 7b, hang counterweight 8b on the screw 15b and constitute tension-applying mechanism after screw 16b is fixedly connected on movable slider 7b below, be provided with rotating shaft 6a, the 6b parallel with the servo-actuated clamper with moving slide-bar 11a, 11b top and constitute two curvature moulds, rotating shaft 6a, 6b are fixed on the fixed support 10 by rotary shaft rack 5a, 5b supporting respectively.

The utility model principle of work: leather sample 21a two is clamped by active clamping head and servo-actuated clamping head respectively, the centre rides on the rotating shaft 6a, direct motor drive crankwheel and connecting rod 2, active sliding block 3 is moved reciprocatingly in vertical direction, sample 21a traction servo-actuated clamping head and slide block 7a also do vertical movement, with being furnished with adjustable weights 8a under the movable slider 7a, weights 8a institute tool gravity, grant sample as constant-tension, slide block is done the very reciprocating while of hanging down, affect the weights motion after forcing sample to scratch fixed rotating shaft, sample scratched that rotating shaft produces subdues the acting in conjunction that motion and weights 8a grant sample 21a constant-tension, has realized the purpose of mentioned strain flexing fatigue detection.When simultaneously two samples being tested as need, sample 21b two is clamped by active clamping head and another servo-actuated clamping head respectively, and the centre rides on the rotating shaft 6b, can test two samples simultaneously.
