Description

Technical Field

[0001] The present invention relates to the technical field of football detection, and particularly relates to a wear resistance test device for footballs. Background Art

[0002] The drum wear resistance testing machine is one of the commonly used devices for testing the wear resistance of footballs. It mainly tests the wear resistance by simulating the rolling and friction of footballs during actual use. During the test, the football is placed inside the drum, and the drum rotates at a certain speed, causing the football to continuously roll inside the drum and generate friction with the inner wall of the drum. After a specified time or number of rotations, the wear condition of the football surface is observed and measured to evaluate the wear resistance of the football. However, in actual football games, there are not only rolling motions but also various complex motion forms and force conditions such as collisions with players' feet and impacts with the goal. The existing drum wear resistance testing machine can only simulate rolling friction and cannot reproduce the wear condition of footballs in real scenarios, resulting in low reference value of the measured data.

[0003] Furthermore, when the existing drum wear resistance testing machine tests the wear resistance of footballs, if multiple footballs are tested simultaneously, the footballs will pile up and collide with each other inside the drum, unable to undergo normal friction, and there is an interference situation between the footballs. Therefore, only one football can be tested for wear resistance at a time, unable to meet the batch testing requirements. Summary of the Invention

[0004] In order to overcome the disadvantages that the existing drum wear resistance testing machine can only simulate rolling friction, cannot reproduce the wear condition of footballs in real scenarios, resulting in low reference value of the measured data, and at the same time, cannot meet the batch testing requirements, the present invention provides a wear resistance test device for footballs.

Detailed Embodiments

[0026] The present invention will be specifically described below with reference to the drawings.

[0029] It also includes a fixing component, a first friction plate 4, a second friction plate 5 and an impact component; a fixing component is arranged on the machine table 1; a first friction plate 4 is arranged on the machine table 1, and artificial turf is arranged on the upper side of the first friction plate 4; a second friction plate 5 is arranged on the machine cover 2, and a frosted surface is arranged on the lower side of the second friction plate 5; an impact component is arranged on the machine cover 2.

[0030] The fixing component includes a direct drive motor 101, a movable frame 102 and a fixing ring 103; the direct drive motor 101 is fixedly connected to the lower side of the machine table 1; the movable frame 102 is rotatably connected to the machine table 1; the output end of the direct drive motor 101 is fixedly connected to the movable frame 102; several fixing rings 103 are slidably connected to the movable frame 102; every two vertically opposite fixing rings 103 form a group.

[0031] Several rail slides 10202 arranged in a circular array are fixedly connected to each movable frame 102; each fixing ring 103 is composed of an electric slide block 10301 and a ring; each electric slide block 10301 slides on the corresponding rail slide 10202.

[0032] It also includes balls 104; several balls 104 arranged in a circular array are rotatably connected to each fixing ring 103.

[0033] The impact component includes a servo motor 201, a bushing 202, a spline shaft 203 and an impact hammer 204; the servo motor 201 is fixedly connected to the upper side of the machine cover 2; the bushing 202 is fixedly connected to the output end of the servo motor 201; the spline shaft 203 is slidably connected to the bushing 202; several impact hammers 204 arranged in a circular array are fixedly connected to the spline shaft 203.

[0034] It also includes a second telescopic driving member 205; the second telescopic driving member 205 is fixedly connected inside the bushing 202, and the second telescopic driving member 205 is an electric push rod; the telescopic end of the second telescopic driving member 205 is fixedly connected to the spline shaft 203.

[0035] Several protrusions 5001 are arranged on the lower side of the second friction plate 5.

[0036] When testing the abrasion resistance of a football, control the telescopic end of the first telescopic driving member 3 to extend, driving the hood 2 and the second friction plate 5 to rise and separate from the machine table 1. Subsequently, the staff places the football to be tested on the upper side of the first friction plate 4, making the lower side of the football fit to the upper side of the first friction plate 4, and making the football located in the two fixed rings 103 opposite to each other up and down. Then, slide the two fixed rings 103 opposite to each other on the movable frame 102 to approach each other, so that the fixed rings 103 limit and fix the football. After the football is fixed, control the telescopic end of the first telescopic driving member 3 to contract, driving the hood 2 and the second friction plate 5 to descend, so that the second friction plate 5 fits to the upper side of the football. Taking the top-down view as the reference, then control the direct drive motor 101 to drive the movable frame 102 and the fixed rings 103 to rotate counterclockwise, so that the fixed rings 103 drive the football to roll counterclockwise between the first friction plate 4 and the second friction plate 5, and test the abrasion resistance of the football. By making the football roll on the first friction plate 4 provided with plastic artificial grass, and at the same time making the football roll on the lower side of the second friction plate 5 provided with protrusions 5001, it simulates the wear situation of the football on the plastic artificial grass in the football field, as well as the wear situation of the football in contact with stones in sandy land, etc., which is conducive to restoring the wear situation of the football in the real scene and improving the reference degree of the abrasion resistance value of the tested football. It should be noted that both the first friction plate 4 and the second friction plate 5 can be replaced with other frosted surfaces, which is conducive to simulating more real scenes for abrasion resistance testing.

[0037] It is also considered that, in view of the influence of the internal air pressure difference of the football on its service life, this equipment supports batch testing of footballs of the same material but different air pressures. Therefore, before the test, the staff places footballs of the same material but different air pressures in the corresponding fixed rings 103. When the footballs roll and contact the first friction plate 4 and the second friction plate 5, by making the footballs of different air pressures contact the upper part of the first friction plate 4 and the lower part of the second friction plate 5 at the same time, the wear conditions of the footballs of different air pressures during the test are made consistent, realizing batch testing of the footballs. After the test is completed, the staff can compare the wear situations between each football, which is conducive to testing the optimal air pressure range when the abrasion resistance of the football is the strongest. Similarly, due to the differences between football materials, the present invention can simultaneously conduct abrasion resistance tests on footballs of the same air pressure but different materials under the same wear conditions, which is conducive to testing the abrasion resistance of footballs of different materials.

[0038] When the fixed rings 103 drive the football to roll counterclockwise between the first friction plate 4 and the second friction plate 5, the football rolls between the two fixed rings 103, and the friction between the football and the fixed rings 103 is reduced by the balls 104, reducing the influence of the fixed rings 103 on the abrasion resistance test of the football. When it is necessary to test the abrasion resistance of footballs of different models and sizes, the distance between every two fixed rings 103 opposite to each other up and down can be adjusted, so that the fixed rings 103 fit to the outer side of the football, which is conducive to testing the abrasion resistance of footballs of different models and sizes and enhancing the adaptability of the equipment.

[0039] It is also considered that in normal use, the football not only rolls, but also is subjected to the kicking force of the player's foot and the force when hitting the goal. Therefore, during the process of the movable frame 102 driving the fixed ring 103 and the football to rotate, with the view from top to bottom as the reference, the servo motor 201 is controlled to drive the sleeve 202 and the spline shaft 203 to rotate counterclockwise together with the movable frame 102, so that the spline shaft 203 drives the impact hammer 204 to rotate counterclockwise, and the rotation speeds are the same. When it is necessary to simulate the situation where the football is impacted, with the view from top to bottom as the reference, the servo motor 201 is controlled to drive the sleeve 202 and the spline shaft 203 to instantaneously accelerate and rotate counterclockwise, so that the spline shaft 203 drives the impact hammer 204 to rotate counterclockwise and impact the football, which is beneficial to simulating the situation where the football is impacted in normal use, enhancing the authenticity of the football wear resistance test, and improving the reference value of the detected football wear resistance value. After the impact hammer 204 impacts the football, the servo motor 201 is controlled to drive the sleeve 202 and the spline shaft 203 to quickly decelerate, so that the spline shaft 203 drives the impact hammer 204 to separate from the football; the impact hammer 204 continues to rotate counterclockwise with the movable frame 102 to avoid interfering with the rotation of the football and prepare for the next impact. When the impact hammer 204 impacts the football, the telescopic driving member two 205 can be controlled to drive the spline shaft 203 to lift and lower, so that the spline shaft 203 drives the impact hammer 204 to lift and lower, which is beneficial to impacting the football from different angles, further enhancing the authenticity of the football wear resistance test, and improving the reference value of the detected football wear resistance value.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figures 2-3 and Figures 5-6 shown, it further includes an exhaust pipe 401; a plurality of cavities 10201 arranged in a circular array are formed on the movable frame 102; a plurality of exhaust pipes 401 arranged in a circular array are fixedly connected to the movable frame 102; each exhaust pipe 401 is communicated with the corresponding cavity 10201; the other end of each exhaust pipe 401 is communicated with an external suction device.

[0042] It further includes a cleaning comb 402; a cleaning comb 402 is fixedly connected to the lower side of each cavity 10201 on the movable frame 102; the cleaning comb 402 is made of elastic hard rubber material.

[0043] The bottom of each impact hammer 204 is set to protrude downward, which is beneficial to enhancing the cleaning effect on the friction plate one 4 while not affecting the normal rotation of the movable frame 102.

[0044] It is also considered that since the wear resistance test of the football takes a long time, when the football rolls and rubs between the friction plate 1-4 and the friction plate 2-5, the football with poor quality has the situation of epidermal debris shedding and falls into the plastic artificial grass in the friction plate 1-4. When testing the next batch of footballs, when the football contacts the plastic artificial grass on the friction plate 1-4, it contacts and rubs against the debris remaining from the previous tested footballs, affecting the contact friction effect between the football and the friction plate 1-4, resulting in a reduced reference value of the wear resistance test of the football. Therefore, when the movable frame 102 drives the fixed ring 103 and the football to rotate, the external air pump is controlled to suck the cavity 10201 through the suction pipe 401, so that the cavity 10201 fits to the plastic artificial grass on the upper side of the friction plate 1-4 for suction, and the debris and impurities falling into it are sucked and collected. At the same time, the cleaning comb 402 is driven by the movable frame 102 to move along the plastic artificial grass on the upper side of the friction plate 1-4, which is beneficial to comb out the debris and impurities for suction and collection, enhancing the cleaning effect on the plastic artificial grass on the friction plate 1-4, preventing the football from contacting and rubbing against the remaining debris, avoiding affecting the contact friction effect between the football and the friction plate 1-4, and ensuring the reference value of the wear resistance test of the football.

[0045] When the suction pipe 401 and the cleaning comb 402 clean the plastic artificial grass on the upper side of the friction plate 1-4, the telescopic driving member 2-5 is controlled to drive the spline shaft 203 and the impact hammer 204 to lift and lower repeatedly, so that the impact hammer 204 collides with the upper side of the friction plate 1-4, and then the elastic material on the upper part of the friction plate 1-4 vibrates, which is beneficial to loosen the remaining debris and impurities, facilitating the cleaning of the impurities by the suction pipe 401 and the cleaning comb 402.
