Description

Technical Field

[0001] This utility model belongs to the technical field of abrasion resistance testing equipment, specifically relating to an abrasion resistance comparison testing device for leather materials. Background Technology

[0002] The material used is artificial leather, a type of plastic product similar to leather. It typically uses a fabric base, onto which a resin mixture is coated or laminated. This mixture is then heated to plasticize it and rolled or embossed to obtain the final product. The abrasion resistance of leather is a crucial factor in determining its quality. Therefore, comparative testing of leather abrasion resistance is necessary. Traditional abrasion resistance testing involves workers applying heavy objects to the surface of the leather for extended periods, typically at least one hour, and then visually observing the degree of wear. This method is inefficient, labor-intensive, and requires two workers to conduct the test on different types of leather. Since different workers apply varying pressure when rubbing, the accuracy of the test is questionable. Therefore, we propose a user-friendly comparative testing device that effectively reduces worker workload and improves test accuracy. Utility Model Content

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-5 The present invention provides the following technical solution: a wear resistance comparison test device for leather materials, including a workbench 1, two symmetrically arranged mounting brackets 2 are fixedly connected to the top of the workbench 1, an opening 3 is provided in the middle of the mounting bracket 2, two drive motors 4 are fixedly connected to the top of the workbench 1, the output shaft of the drive motor 4 passes through the opening 3 and is fixedly connected to a rotating rod 5, a mounting assembly 6 is installed on the top of the rotating rod 5, a connecting column 7 is fixedly connected to one side of the top of the mounting bracket 2, a connecting plate 8 is installed on the top of the connecting column 7, a placement cylinder 9 is installed on the surface of the connecting plate 8, a weight 10 is placed inside the placement cylinder 9, and two detection components 11 are installed on the surface of the workbench 1, the two detection components 11 are respectively located on the back of the two mounting brackets 2.

[0014] In this embodiment, the mounting assembly 6 includes a circular mounting plate 61 and a fixing sleeve 62 sleeved on the outside of the mounting plate 61. The rotating rod 5 is fixedly connected to the bottom end of the mounting plate 61. Leather is installed on the surface of the mounting plate 61. A through slot 63 is opened in the middle of the fixing sleeve 62. A locking screw hole 64 is opened on the side of the fixing sleeve 62. A fastening bolt 65 for fixing the leather is threaded into the locking screw hole 64. The placement cylinder 9 is located at the top of the slot 63.

[0015] Specifically, after placing the leather on the surface of the mounting plate 61, the fixing sleeve 62 is fitted onto the outside of the mounting plate 61. The fixing sleeve 62 can then press the leather together. The leather is then locked and fixed by tightening the locking screw hole 64. The weight 10 is placed inside the placement cylinder 9. Since the placement cylinder 9 is located at the top of the slot 63, the bottom of the weight 10 will fall onto the surface of the leather through the slot 63 after the weight 10 is placed inside the placement cylinder 9, thus facilitating the wear resistance comparison test of the leather.

[0016] In this embodiment, the detection component 11 includes a fixed frame 12 fixedly mounted on the surface of the workbench 1. The top of the fixed frame 12 is integrally provided with a horizontal extension 121. The surface of the extension 121 is provided with a through strip hole 13. The bottom of the extension 121 is provided with a mounting member 14. An industrial camera 15 is fixedly mounted in the mounting member 14. A screw 20 is fixedly mounted on the top of the mounting member 14. The screw 20 passes through the strip hole 13 and is threadedly connected to a nut 21.

[0017] Specifically, the screw 20 and nut 21 are used to fix the mounting part 14, and the strip hole 13 is used to adjust the position of the industrial camera 15, so that the industrial camera 15 can take pictures of the wear on the leather surface. Compared with the method of judging by the naked eye, this method can improve the accuracy of the operator's judgment of the wear degree of the leather.

[0018] In this embodiment, the industrial camera 15 is located at the top of the slot 63.

[0019] Specifically, this method enables the industrial camera 15 to photograph the worn areas on the leather surface.

[0020] In this embodiment, the top of the connecting column 7 is provided with a first fixing screw hole 16, and both ends of the connecting plate 8 are provided with second fixing screw holes 17. The first fixing screw hole 16 and the second fixing screw hole 17 are aligned and are internally threaded with fixing screws 18.

[0021] Specifically, the connecting plate 8 can be disassembled and assembled by using the fixing screw 18 in conjunction with the first fixing screw hole 16 and the second fixing screw hole 17. Furthermore, the connecting plate 8 can be rotated to place the placement cylinder 9 in different positions within the slot 63, thereby enabling wear resistance testing of different positions on the leather.

[0022] In this embodiment, the distance between the connecting plate 8 and the mounting plate 61 is greater than the width of the fixing sleeve 62.

[0023] Specifically, this method allows workers to easily remove the fixing sleeve 62 after unscrewing the fastening bolt 65.

[0024] In this embodiment, a controller 19 with timing function is installed on the surface of the workbench 1, and the two drive motors 4 are synchronously controlled by the controller 19. The industrial camera 15 is connected to an external terminal.

[0025] Specifically, the two drive motors 4 are synchronously controlled by the controller 19. The controller 19 has a timing function. When the operator conducts the comparative test, the controller 19 is timed for no less than one hour. Therefore, it can ensure that the two types of leather are tested for wear resistance under the same friction time. This method can effectively reduce the labor intensity of the operator. The wear area photos taken by the industrial camera 15 are transmitted to the operator's terminal. Therefore, the operator can judge the degree of wear on the surface of the two leathers based on the transmitted photos. Compared with the method of judging by the naked eye, this judgment method can improve the accuracy of the comparative test.

[0026] Working principle: Two pieces of leather are installed in the mounting assembly 6 respectively. Then, weights 10 of the same weight are placed in the two placement cylinders 9. The drive motor 4 drives the rotating rod 5 to rotate, which in turn causes both mounting assemblies 6 to start rotating. The leather is then subjected to a friction test under the action of the weights 10. The two weights 10 can be used to conduct a wear resistance comparison test on two different pieces of leather. The two different pieces of leather are tested for wear resistance under the same friction weight and the same friction time. The detection component 11 takes pictures of the worn parts. This method can improve the accuracy of the comparison test.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
