Description

Technical Field

[0001] This utility model relates to the field of shoe sole abrasion resistance testing technology, specifically to a shoe sole abrasion resistance testing cyclic friction table. Background Technology

[0002] Abrasion resistance of shoe soles is a crucial indicator of footwear quality and lifespan, directly impacting comfort, safety, and economic value. With the continuous development of the footwear market and increasing consumer demands for durability, abrasion resistance testing technology has gradually become a key aspect of footwear research and development and quality control. Traditional abrasion resistance testing primarily assesses the abrasion resistance of sole materials by simulating the friction between the sole and the ground during actual wear, thus providing a scientific basis for improving sole materials and designing sole structures.

[0003] Currently, most shoe sole abrasion testing devices on the market are planar, integral sole friction testing equipment. These devices typically use a single abrasive belt or friction surface to perform a uniform friction and wear test on the entire sole surface. Although this method is simple in structure and easy to operate, it has significant shortcomings. First, sole wear is mainly concentrated in two key areas: the forefoot and heel. However, the integral planar friction test cannot differentiate between these two key wear areas, causing other parts of the sole to participate in friction during the test, producing a compensatory effect, which in turn affects the accurate assessment of the actual abrasion resistance of the sole.

[0004] Therefore, this solution proposes a cyclic friction test bench for shoe sole abrasion resistance to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a cyclic friction test platform for shoe sole abrasion resistance.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: A cyclic friction test platform for shoe sole abrasion resistance includes a base, a vertical support plate mounted on the top of the base, two rollers rotatably mounted on the front of the vertical support plate, a tension shaft above each roller, a sanding belt tensioned between each roller and the tension shaft above it, a sliding pin docked at the rear end of each tension shaft, the two sliding pins correspondingly slidingly engaging with the interior of two arc-shaped sliding rails on the vertical support plate, an adjustment mechanism for adjusting the distance between the sliding pins on both sides is installed on the back side of the vertical support plate, a lead screw guide rail is installed at the center of the top front side of the vertical support plate, a negative pressure adsorption cover is installed at the front end of the slider on the lead screw guide rail, the shoe sole to be tested is horizontally adsorbed on the bottom surface of the negative pressure adsorption cover, and a synchronous drive component for synchronously driving the rotation of the two rollers is also installed on the back side of the vertical support plate.

[0007] Preferably, the center of the arc-shaped sliding rail is concentric with the center of the front end face of the roller.

[0008] Preferably, the adjusting mechanism includes a mounting frame, an adjusting drive, and telescopic links. The mounting frame is installed on the top of the back side of the vertical support plate and distributed along its length. There are two telescopic links, both vertically distributed, and their telescopic ends are respectively connected to the rear ends of two sliding pins. The adjusting drive is installed in the mounting frame as a component for adjusting the distance between the telescopic links on both sides.

[0009] Preferably, the pitch adjustment drive includes a double-ended lead screw, a lead screw sleeve, and a motor. The double-ended lead screw is rotatably installed inside the mounting frame and distributed along its length. The lead screw sleeve has two threads that are respectively threaded onto both ends of the double-ended lead screw. The bottom walls of the two lead screw sleeves are respectively fixedly connected to the top ends of two telescopic connecting rods. The motor is mounted on the right end of the mounting frame, and its output end is connected to the right end of the double-ended lead screw via a coupling.

[0010] Preferably, a vacuum pump is installed on the top of the negative pressure adsorption hood.

[0011] Preferably, the synchronous drive component includes a motor mounting bracket, a second motor, a first gear, a second gear, and a docking shaft. The motor mounting bracket is installed on the back side of the vertical support plate as the mounting structure for the second motor. The first gear is connected to the output end of the second motor via a coupling. The second gear has two symmetrical meshing parts on the left and right sides of the first gear. The docking shaft has two parts respectively connected between the second gear on both sides and the rollers on both sides.

[0012] The beneficial effects of this utility model are reflected in:

[0013] This cyclic friction test bench for sole abrasion resistance utilizes a dual-belt independent friction pair structure to accurately simulate the actual wear conditions of the sole's forefoot and heel. This avoids testing errors caused by compensatory friction from other parts in traditional full-sole friction tests, thus providing a more realistic and accurate reflection of the sole's abrasion resistance during daily walking. The adjustable distance mechanism allows for flexible adjustment of the gap between the tops of the two sanding belts, accommodating differences in the distance between the forefoot and heel of different sole sizes. This enables targeted and personalized abrasion resistance testing, greatly enhancing the test's applicability and practical value. Furthermore, the negative pressure suction hood combined with the lead screw guide rail design ensures the sole's stable fixation and precise positioning during testing, preventing displacement and ensuring the stability and repeatability of the test data. The synchronous drive unit coordinates the operation of the two sanding belts, ensuring not only uniform friction but also improved testing efficiency and equipment reliability.

[0014] In summary, this device, with its scientifically designed structure and multifunctional adjustment capabilities, enables efficient and accurate testing of key wear areas on shoe soles, providing a solid technical guarantee for evaluating the abrasion resistance of shoe sole materials. It has significant application value and broad market prospects. Attached Figure Description

[0030] It should be noted that if the utility model embodiment involves directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0031] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.

[0032] Please refer to the instruction manual appendix. Figures 1-6 This utility model provides a cyclic friction test platform for shoe sole abrasion resistance testing.

[0033] Example 1:

[0034] like Figure 1 and Figure 2 As shown, a cyclic friction test bench for shoe sole abrasion resistance mainly includes a base 1, a vertical support plate 2, a sanding belt 3, a roller 4, a tensioning shaft 5, an adjustment mechanism 6, a sliding pin 7, a negative pressure adsorption cover 8, a lead screw guide rail 9, and a synchronous drive component 10.

[0035] The base 1 serves as the supporting foundation for the entire device and is typically made of metal to ensure the stability of the overall structure. The vertical support plate 2 is fixedly assembled to the top of the base 1, serving as the main mounting carrier for other functional components.

[0036] On the front of the vertical support plate 2, two rollers 4 are rotatably mounted via bearing seats and other structures. The two rollers 4 are arranged symmetrically from left to right. A tensioning shaft 5 is positioned directly above each roller 4. Each sanding belt 3 is tensioned and wound around one roller 4 and the tensioning shaft 5 above it, forming an independent friction pair. The tops of these two independent friction pairs can simultaneously conduct friction tests on the forefoot and heel of the shoe sole. This testing method better reflects the wear and tear on shoe soles during daily walking, thus eliminating the need for a complete friction test of the entire sole surface. Such tests would result in additional friction compensation in other areas, affecting the true abrasion resistance of the sole. The rough surface of the sanding belt 3 faces outwards to simulate actual wear conditions.

[0037] To adjust the spacing of the friction section at the top of the sanding belt 3 (primarily for testing different spacing between the forefoot and heel of shoe soles of different sizes), a sliding pin 7 is fixedly connected to the rear end of each tensioning shaft 5. Two arc-shaped sliding rails 21 are correspondingly provided on the vertical support plate 2, and the two sliding pins 7 are slidably engaged inside these two arc-shaped sliding rails 21. Preferably, the center of the arc-shaped sliding rail 21 is concentric with the center of the front end face of the corresponding side roller 4. This design ensures that the wrapping tension between the sanding belt 3 and the roller 4 remains constant when the tensioning shaft 5 moves within the arc-shaped sliding rails 21, preventing it from affecting the performance of the sanding belt 3.

[0038] A distance adjustment mechanism 6 is installed on the back side of the vertical support plate 2. This mechanism synchronously adjusts the positions of the sliding pins 7 on both sides within their respective arc-shaped sliding rails 21, thereby controlling the distance between the two tensioning shafts 5. In this embodiment, the distance adjustment mechanism 6 includes a mounting frame 61, a distance adjustment drive component 62, and telescopic connecting rods 63. The mounting frame 61 is fixedly installed on the top of the back side of the vertical support plate 2 and distributed along its length direction (i.e., left-right direction). There are two telescopic connecting rods 63, both vertically distributed. Their fixed ends are connected to the distance adjustment drive component 62, and their telescopic ends are respectively fixedly connected downwards to the rear ends of the two sliding pins 7. The distance adjustment drive component 62, as a power source, is installed within the mounting frame 61 and drives the two telescopic connecting rods 63 to move synchronously towards or away from each other, thereby controlling the relative sliding of the two sliding pins 7 and achieving the distance adjustment operation.

[0039] Furthermore, one specific implementation of the pitch adjustment drive component 62 includes a double-ended lead screw 621, a lead screw sleeve 622, and a motor 623. The double-ended lead screw 621 is rotatably mounted inside the mounting frame 61 via bearings, with its axis arranged along the length of the mounting frame 61. There are two lead screw sleeves 622, which are threaded onto the left-hand and right-hand threaded sections of the double-ended lead screw 621, respectively. The bottom walls of the two lead screw sleeves 622 are fixedly connected to the top ends of the two telescopic connecting rods 63, respectively. The motor 623 is mounted on the right end of the mounting frame 61 via a motor mount, and its output end is connected to the right end of the double-ended lead screw 621 via a coupling. When the motor 623 starts, it drives the double-ended lead screw 621 to rotate, causing the two lead screw sleeves 622 to move synchronously towards or away from each other along the double-ended lead screw 621. This, in turn, drives the two sliding pins 7 to slide within the arc-shaped sliding rail 21 via the telescopic connecting rods 63, thereby adjusting the distance between the two tensioning shafts 5.

[0040] A lead screw guide rail 9 is installed at the center of the top front of the vertical support plate 2. A slider on the lead screw guide rail 9 can move precisely along the guide rail direction (usually the front-to-back direction). A negative pressure adsorption cover 8 is mounted to the front end of this slider via a connecting plate. The sole of the shoe to be tested is horizontally adsorbed onto the bottom surface of the negative pressure adsorption cover 8. Specifically, a vacuum pump 81 can be installed on the top of the negative pressure adsorption cover 8 to generate negative pressure by drawing a vacuum, firmly adsorbing the sole onto the cover and preventing displacement during testing.

[0041] The synchronous drive unit 10 is installed on the back side of the vertical support plate 2 and is used to synchronously drive the two rollers 4 to rotate in the same or opposite directions. In this embodiment, the synchronous drive unit 10 includes a motor mounting bracket 101, a second motor 102, a first gear 103, a second gear 104, and a docking shaft 105. The motor mounting bracket 101 is fixed to the back side of the vertical support plate 2 and is used to install the second motor 102. The first gear 103 is installed on the output shaft of the second motor 102 via a coupling. There are two second gears 104, which symmetrically mesh with the left and right sides of the first gear 103. There are two docking shafts 105, one end of which is connected to the corresponding second gear 104 via a coupling or keyway, and the other end passes through a through hole (usually sealed by a bearing) on ​​the vertical support plate 2 and is connected to the rotating shaft of the corresponding roller 4. When motor 102 starts, it drives gear 103 to rotate, which in turn drives two gears 104 to rotate at the same speed but in opposite directions. Finally, through the docking shaft 105, it drives two rollers 4 to rotate synchronously in opposite directions, causing the two sanding belts 3 to circulate and perform friction and wear tests on the shoe soles adsorbed on the negative pressure adsorption cover 8. The lead screw guide rail 9 can drive the shoe sole to move slowly downwards, so that the shoe sole can descend to fit against the friction test section at the top of the sanding belts 3 on both sides.

[0042] Working Principle: During use, the vacuum pump 81 is activated, first adsorbing and fixing the sole to be tested onto the bottom surface of the negative pressure adsorption cover 8. Based on the sole's dimensions (i.e., the distance between the insole and heel), the distance between the two tension shafts 5 is adjusted via the adjusting mechanism 6 (starting motor 623), thereby changing the distance between the top friction test sections of the two sanding belts 3. Then, the synchronous drive component 10 (motor 102) is activated, driving the two sanding belts 3 to circulate at high speed. Subsequently, the lead screw guide rail 9 can be activated, causing the negative pressure adsorption cover 8 and the sole adsorbed at its bottom to descend until the insole and heel areas of the sole are lowered and in contact with the top friction test sections of the sanding belts 3 on both sides. The sole continuously rubs against the high-speed moving sanding belts 3. After a set time or number of cycles, the test is stopped, the sole is removed, and its wear condition is observed to evaluate its abrasion resistance.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
