Description

Technical Field

[0001] This utility model relates to the field of testing resin leather technology, specifically to a leather abrasion resistance testing device. Background Technology

[0002] Leather is animal hide that has been modified and is not easily perishable through physical and chemical processing such as hair removal and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space, and its surface has a special grain layer with natural grain and luster, and a comfortable feel.

[0003] In the current technology, leather has been integrated into various industries. Therefore, there are certain standards for leather production. Various tests are required during leather production, including abrasion resistance tests. However, in the current technology, the abrasion resistance test of leather usually only involves simple polishing to test whether the leather is abrasion resistant. However, since different types of leather can withstand different weights of different customers when used by different customers, there is an urgent need to propose a method that can test the abrasion resistance of leather under different weights during the abrasion resistance test. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leather abrasion resistance testing device. This device addresses the issue that different types of leather can withstand varying weights from different customers, thus necessitating a technical solution to test the abrasion resistance of leather under different weights during abrasion resistance testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leather abrasion resistance testing device includes a test chamber. A first cylinder is installed at the bottom of the test chamber, with its telescopic end extending vertically upwards into the test chamber. A telescopic plate to prevent leather dander from splashing is fixedly installed at the top of the test chamber, with the fixed section of the telescopic plate located on the inner top wall of the test chamber. The movable section of the telescopic plate is fixedly connected to the telescopic end of the first cylinder. A clamping assembly capable of firmly holding the leather is provided on each side of the telescopic plate, and a pressing assembly for applying pressure to the leather is installed on the clamping assembly. A horizontally arranged platform plate is also fixed on the movable section of the telescopic plate, and a friction testing assembly facing the leather is installed at each end of the platform plate.

[0007] Working principle:

[0008] When operators need to conduct abrasion resistance tests on different types of leather, they first place two pieces of leather of the same size into the test chamber. The clamping components inside the test chamber securely hold the two pieces of leather, ensuring that the leather is not taut during clamping. Next, the operator activates the first cylinder, which moves the platform plate vertically. The platform plate then moves the two friction testing components toward the clamped leather until the leather comes into contact with the friction wheel. The operator then continuously applies weight from the pressure components, applying different weights through the two pressure components to determine how much friction each piece of leather can withstand.

[0009] The beneficial effects of this utility model are as follows:

[0010] The first cylinder allows for simultaneous testing of two friction testing components, ensuring consistency in the experiment. The clamping component ensures the leather to be processed is in a stable state, while the pressing component continuously adds weight to the leather to determine its abrasion resistance.

Detailed Implementation

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1As shown, a leather abrasion resistance testing device includes a test chamber 1. A first cylinder 2 is installed at the bottom of the test chamber 1, with its telescopic end extending vertically upwards into the test chamber 1. A telescopic plate 3 is fixedly installed on the top of the test chamber 1 to prevent leather dander from splashing. The fixed section of the telescopic plate 3 is located on the inner top wall of the test chamber 1, and the movable section of the telescopic plate 3 is fixedly connected to the telescopic end of the first cylinder 2. A clamping assembly capable of firmly holding the leather is provided on each side of the telescopic plate 3. The clamping assembly includes an L-shaped clamping plate 8, an extension plate 9, and two bolts 10. The extension plate 9 is fixedly installed on the inner wall of the test chamber 1, and the clamping plates 8 are both fixedly installed on the top wall of the test chamber 1, located on one side of the fixed section of the telescopic plate 3. The extension plate 9 and the clamping plates 8 are opposite each other, and a groove 11 for placing the leather is provided on the opposite side of the extension plate 9 and the clamping plates 8. The two bolts 10 are respectively screwed... The pressure groove 11 passes through the extension plate 9 and the clamping plate 8 to stabilize the leather. The clamping assembly is equipped with a pressing component for applying pressure to the leather. The pressing component includes a pressure plate 12, a screw 13 and several counterweights 14. The pressure plate 12 is located between the clamping plate 8 and the extension plate 9. The screw 13 is vertically fixed in the middle of the pressure plate 12, and several counterweights 14 can be respectively sleeved on the screw 13. A horizontally arranged platform plate 4 is also fixed on the movable section of the telescopic plate 3. A friction test component facing the leather is installed at both ends of the platform plate 4. The friction test component includes a motor 5, a vertically arranged first rotating shaft 6 and a friction wheel 7. The motor 5 is fixedly installed at one end of the platform plate 4, the first rotating shaft 6 is fixedly installed at the output end of the motor 5, and the friction wheel 7 is fixedly installed on the first rotating shaft 6 and faces the leather.

[0016] When operators need to conduct abrasion resistance tests on different types of leather, they first place two pieces of leather of the same size into the test chamber 1. The ends of the leather are then placed into the grooves 11 of the clamping plate 8 and the extension plate 9. Next, the operators tighten the bolts 10 on the clamping plate 8 and the extension plate 9, fixing the ends of the leather but not taut, thus securing it firmly between the clamping plate 8 and the extension plate 9. Then, the operators place the pressure plate 12 on top of the leather, with both ends of the pressure plate 12 tightly fitted between the clamping plate 8 and the extension plate 9. Finally, the operators activate the first cylinder 2, which moves the platform plate 4. Plate 4 drives two motors 5 to move vertically. Then, the operator starts motor 5, which drives the first rotating shaft 6 to rotate. The first rotating shaft 6 drives the friction wheel 7 to rotate. At this time, the two friction wheels 7 simultaneously perform a friction test on the stabilized leather. Then, the friction wheel 7 is raised so that the friction surface of the friction wheel 7 comes into contact with the leather, and the friction wheel 7 slightly lifts the leather. Then, the number of counterweights 14 is continuously added to the pressure plate 12 on one side of the leather until a large amount of leather flakes are generated when the friction wheel 7 rubs against the leather, and then the addition of counterweights 14 is stopped. In this way, the abrasion resistance weight of the two leathers can be compared after the two leathers have been tested.

[0017] like Figure 1 and Figure 2 As shown, it also includes two soft pads 15, which are fixedly installed on the bottom of the bolt 10 and located in the pressure groove 11. The bottom of the test box 1 is provided with two protrusions 16 that slope downward from the middle to both sides. The bottom of the side walls on both sides of the test box 1 is provided with a long strip through groove 17, and the two sides of the two protrusions 16 slope downward to the two long strip through grooves 17. The outside of the test box 1 is provided with a hinge door 18.

[0018] The soft pad 15 prevents the leather from being crushed by the bolt 10 when it is fixed. The protrusion 16 facilitates the collection of leather scraps generated during the abrasion resistance test and allows them to be recycled through the long strip grooves 17 on both sides of the test chamber 1. The hinge door allows the leather to be placed into the test chamber 1 for testing.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
