Description

Technical Field

[0001] The utility model relates to the technical field of synthetic leather testing devices, in particular to a water-based synthetic leather bending resistance testing device. Background Art

[0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute for it. It is usually made of impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. Both its front and back sides are very similar to leather and have a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather and is widely used in the production of shoes, boots, bags and balls. Water-based synthetic leather is a synthetic leather made by replacing all solvents such as DMF with chemical materials using water as solvent, and coating the adhesive layer, foaming layer, surface layer and surface treatment layer of this water solvent on the surface of the base fabric.

[0003] The existing patent (publication number CN214952582U) can only perform a bending resistance test on the middle part of the leather body, and the test process cannot truly reflect the performance of the material in actual application. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water-based synthetic leather bending resistance testing device comprises a bottom plate, support rods are fixedly installed at the four corners of the top of the bottom plate, a top plate is fixedly installed on the top of the support rods, a transverse slide groove is provided at the middle position of the bottom of the top plate, a plurality of folding plates are slidably connected in the transverse slide groove, a fixed plate is fixedly installed at the left end position of the top of the top plate, and a driving motor is fixedly installed at the right end position of the bottom of the fixed plate, the driving motor is fixedly connected with a threaded rod through the output end on the left side thereof, the other end of the threaded rod passes through a plurality of folding plates in sequence and is movably connected to the fixed plate through a bearing, a groove is provided at the right side position in the transverse slide groove, and a counting component is arranged in the groove, the counting component comprises an electrode sheet 1, an electrode sheet 2 is arranged below the electrode sheet 1, and a semicircular button is fixedly installed at the bottom of the electrode sheet 2.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The water-based synthetic leather bending resistance test device can simulate the repeated bending and stretching of synthetic leather in actual use through the design of the driving motor and the threaded rod. This simulation test is crucial for evaluating the bending resistance of synthetic leather because it can more realistically reflect the performance of the material in actual application.

[0008] The water-based synthetic leather bending resistance test device is equipped with a counter that can accurately record the number of times the synthetic leather is bent during the test. This function not only simplifies the data collection during the test, but also provides a quantitative basis for subsequent performance analysis and material improvement.

[0009] The water-based synthetic leather bending resistance test device has a dual fixing design of slot and magnetic adsorption, which ensures the stability of the synthetic leather during the test. This design prevents the material from sliding or shifting during the test, thereby improving the accuracy and reliability of the test results.

[0010] The entire test device has a compact structure and all components work together to make the test process more efficient. At the same time, the easy-to-operate design lowers the usage threshold, allowing non-professionals to easily master the test method. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4The utility model provides a technical solution: a water-based synthetic leather bending resistance testing device, comprising a bottom plate 1, support rods 2 are fixedly installed at the four corners of the top of the bottom plate 1, a top plate 3 is fixedly installed on the top of the support rod 2, a transverse slide groove 13 is provided at the middle position of the bottom of the top plate 3, a plurality of folding plates 6 are slidably connected in the transverse slide groove 13, a fixed plate 7 is fixedly installed at the left end position of the top of the top plate 3, and a driving motor 4 is fixedly installed at the right end position of the bottom of the fixed plate 7, the driving motor 4 is fixedly connected with a threaded rod 5 through the output end on the left side thereof, the other end of the threaded rod 5 sequentially penetrates the plurality of folding plates 6 and is movably connected to the fixed plate 7 through a bearing, a groove is provided at the right side position in the transverse slide groove 13, and a counting component 14 is arranged in the groove, the counting component 14 comprises an electrode sheet 15, an electrode sheet 2 17 is arranged below the electrode sheet 15, and a semicircular button 18 is fixedly installed at the bottom of the electrode sheet 2 17.

[0018] Slots 12 are provided near the top of the fixed plate 7 and the plurality of folding plates 6 , and a synthetic leather body 8 is movably arranged between the plurality of slots 12 .

[0019] The folding plate 6 and the threaded rod 5 are threadedly connected.

[0020] A metal sheet 10 is symmetrically fixedly mounted on the fixed plate 7 and the folding plate 6 which is farthest from the fixed plate 7 , and a fixed magnetic sheet 9 is magnetically adsorbed on the metal sheet 10 .

[0021] The four corners of the top of the second electrode sheet 17 are fixedly connected to the inner wall of the groove through springs 16 .

[0022] A counter 11 is fixedly mounted on the right end of the front side of the top plate 3 , and the counter 11 is electrically connected to the electrode sheet 15 via a wire.

[0023] First, the water-based synthetic leather body 8 to be tested is placed between the fixing plate 7 and the slots 12 of the plurality of folding plates 6. In order to ensure that the leather body does not slide or shift during the test, in addition to the clamping effect of the slots 12, the stability of the leather body is further enhanced by the magnetic adsorption between the fixing magnetic sheet 9 and the metal sheet 10. This double fixing design ensures the accuracy and reliability of the test.

[0024] Next, the driving motor 4 is started, and the driving motor 4 drives the threaded rod 5 to rotate through its output end. Since the folding plate 6 and the threaded rod 5 are threadedly connected, when the threaded rod 5 rotates, the folding plate 6 will slide laterally in the transverse chute 13 and move along the axial direction of the threaded rod 5.

[0025] As the folding plates 6 move, they drive the synthetic leather body 8 clamped therein to bend and stretch, thereby simulating the bending resistance of the synthetic leather in actual use.

[0026] When the folding plate 6 drives the synthetic leather body 8 to bend to a certain extent, the bottom of the leather body will contact the semicircular button 18. The semicircular button 18 moves downward under pressure, so that the electrode sheet 2 17, which was originally kept at a certain distance from it, contacts the electrode sheet 1 15. This contact triggers the counter 11 connected to the electrode sheet 1 15 through a wire, and records the next bending action. The counter 11 is used to count the number of times the leather body is bent during the test, providing a basis for evaluating its bending resistance performance.

[0027] The four corners of the top of the electrode sheet 17 are fixedly connected to the inner wall of the groove through the spring 16, ensuring that the electrode sheet 17 can be quickly reset when not under pressure, so as to be ready for the next contact.

[0028] By repeating the above process, the device can simulate the repeated bending and stretching of synthetic leather in actual use and comprehensively evaluate its bending resistance. At the same time, the recording function of the counter 11 provides valuable data support for subsequent performance analysis and improvement.
