Description

Technical Field

[0001] The present invention relates to the field of football detection equipment, and in particular to a quality detection equipment for football production. Background Art

[0002] Football quality detection is a comprehensive and strict process, involving multiple detection items and standards. Through laboratory and on-site tests, it is ensured that the football meets the requirements for daily long-term use in terms of performance, accuracy, and durability. Existing football quality detection equipment generally places the football in a sealed rotating cylinder, drives the football to continuously roll through the rotating cylinder to detect the wear resistance of the football, and at the same time uses the continuously flowing water in the rotating cylinder to collide with the football to detect whether the waterproof performance of the football is qualified. In this process, the impact force generated by simply driving the football to rotate by the rotating cylinder on the football is relatively small, and it is impossible to simulate the environmental scenarios where the football continuously impacts the lawn, gravel ground, and cement ground during daily use. Therefore, there are great simulation limitations in the wear resistance detection of the football. Moreover, when there are small cracks in the football, the impact force on the football is relatively small, and it cannot cause external moisture to penetrate through the cracks into the interior of the football, so it is impossible to determine whether the football really has small cracks. Therefore, there are also great simulation limitations in the waterproof performance detection of the football. Summary of the Invention

[0003] In order to overcome the disadvantages that the existing football quality detection equipment generates a relatively small impact force on the football and there are great simulation limitations in both the wear resistance detection and the waterproof performance detection, the present invention provides a quality detection equipment for football production.

At the same time, the circulating sandblaster sprays sand grains between the lower cabin shell and the upper cabin shell in a cycle, effectively improving the impact simulation effect of the football in the live ground environment and strengthening the work intensity of the wear resistance detection of the football. In addition, a heating lamp is also provided, which cooperates with the spray liquid sprayed by the spray nozzles between the lower cabin shell and the upper cabin shell to generate a large amount of water vapor, strengthening the work intensity of the waterproof performance detection of the football.

Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1 A quality inspection device for football production, as Figures 1-7As shown in the figure, it includes a circulating sandblaster 1, a sand outlet pipe 11, a sand return hopper 12, a lower cabin shell 21, an upper cabin shell 22, a push rod 23, a compression spring 24, a heating lamp 27, an electric rotary machine 3, a rotating table 31, a fixed cone 32, a collision plate 33, an annular diversion basin 4 and an annular partition 42; an electric rotary machine 3 is installed on the circulating sandblaster 1; a rotating member of the electric rotary machine 3 is fixedly connected with a rotating table 31; the circulating sandblaster 1 is fixedly connected with a lower cabin shell 21; the rotating table 31 is located at the inner bottom of the lower cabin shell 21, and there is an annular gap between the rotating table 31 and the lower cabin shell 21; a sand transportation cavity 3101 structure is opened in the rotating table 31; the sand outlet pipe 11 of the circulating sandblaster 1 is rotatably connected and communicated with the sand transportation cavity 3101 of the rotating table 31; a sand return hopper 12 aligned with the annular gap is fixedly connected inside the lower cabin shell 21; the outlet end of the sand return hopper 12 is communicated with the circulating sandblaster 1; a fixed cone 32 is fixedly connected to the rotating table 31; a plurality of sandblasting ports 3201 structures communicating with the sand transportation cavity 3101 of the rotating table 31 are opened on the fixed cone 32; three collision plates 33 are fixedly connected to the fixed cone 32; the upper cabin shell 22 is rotatably connected to the lower cabin shell 21; a ball clamping groove 2201 structure is opened at the inner top of the upper cabin shell 22; a push rod 23 aligned with the ball clamping groove 2201 is slidably connected to the upper cabin shell 22; a compression spring 24 is fixedly connected between the push rod 23 and the upper cabin shell 22; a heating lamp 27 is installed at the inner top of the upper cabin shell 22; an annular diversion basin 4 is fixedly connected inside the lower cabin shell 21; an annular partition 42 is fixedly connected between the annular diversion basin 4 and the rotating table 31. Only sand grains can smoothly pass through the partition gaps of the annular partition 42 and enter the sand return hopper 12 to flow back into the circulating sandblaster 1, and the annular partition 42 intercepts the debris falling off the football surface due to intense friction.

[0020] As Figure 1 , Figure 3 and Figure 4 shown, a circle of lower friction plates 25 is fixedly connected to the inner surface of the lower cabin shell 21; a circle of upper friction plates 26 is fixedly connected to the inner surface of the upper cabin shell 22; both the lower friction plates 25 and the upper friction plates 26 use steel plate materials with friction convex block structures on the surface. The lower friction plates 25 and the upper friction plates 26 made of steel plate materials can improve the collision strength between them and the football, simulating the simulation scenarios such as the football colliding with a football frame or guardrail made of steel materials; anti-slip groove structures are opened on the surfaces of the three collision plates 33. The anti-slip groove structures can strengthen the impact effect of the collision plates 33 on the football and prevent the collision plates 33 from slipping during the impact on the football and weakening the impact force on the football.

[0021] The following are the operation steps of a quality inspection device for football production using the present invention.

[0022] First, the operator places the football card to be detected in the ball slot 2201 of the upper housing 22. Then, the operator covers the upper housing 22 onto the lower housing 21, so that the upper housing 22 and the lower housing 21 together form a closed detection space. Next, the operator turns on the circulating sandblaster 1 and the electric rotary machine 3. The electric rotary machine 3 drives the rotating table 31 to rotate rapidly. The circulating sandblaster 1 continuously conveys sand grains to the sand input cavity 3101 of the rotating table 31 through the sand output pipe 11. The sand grains are sprayed upward successively through the sandblasting ports 3201 of the fixed cone 32. The sprayed sand grains flow through the annular partition 42 along the inner surfaces of the upper housing 22, the lower housing 21, and the annular diversion basin 4 and then flow into the sand return hopper 12. The sand grains then flow back to the circulating sandblaster 1 along the sand return hopper 12, realizing the circulating flow of sand grains on the inner surfaces of the upper housing 22 and the lower housing 21.

[0023] After that, the operator presses the push rod 23 to drive the compression spring 24 to compress. At the same time, the push rod 23 pushes the football clamped in the ball slot 2201 downward into the lower housing 21. The electric rotary machine 3 drives the impact plate 33 to rotate rapidly and continuously impact the football, causing the football to collide violently between the upper housing 22, the lower housing 21, and the impact plate 33. At the same time, the football will also continuously rub violently against the sand grains on the inner surfaces of the upper housing 22 and the lower housing 21, as well as the lower friction plate 25 and the upper friction plate 26, effectively improving the impact simulation effect of the football in the live ground environment and strengthening the work intensity of the wear resistance detection of the football.

[0024] During this process, the heating lamp 27 continuously heats the detection space between the upper housing 22 and the lower housing 21, heating the sand grains to a scalding state. When the football rubs violently against the scalding sand grains, it can simulate the simulation environment of the football being used on a sun-exposed gravel field, further strengthening the work intensity of the wear resistance detection of the football.

[0025] Embodiment 2 As Figures 1-7 shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, an infusion pipe 28 is fixedly connected to the upper housing 22, and the infusion pipe 28 is externally connected to the liquid output port of the spray liquid circulation conveying device; a plurality of nozzles 281 are connected to the infusion pipe 28; a retaining ring 43 is slidably connected to the annular partition 42; an electric elevator 44 is installed on the circulating sandblaster 1; the telescopic end of the electric elevator 44 is fixedly connected to the retaining ring 43. In the initial state, the electric elevator 44 pushes the retaining ring 43 upward to above the annular partition 42. During the process of the circulating sandblaster 1 circulatingly spraying sand grains into the upper housing 22 and the lower housing 21, the sand grains can smoothly pass through the annular partition 42 and flow back to the circulating sandblaster 1.

[0026] After the sandblasting work of the circulating sandblaster 1 is completed, the electric elevator 44 pulls the retaining ring 43 downward to block the outside of the annular partition 42. The externally connected spray liquid circulating and conveying device continuously sprays the spray liquid downward between the inner parts of the lower cabin shell 21 and the upper cabin shell 22 through each spray head 281 on the infusion pipe 28. The spray liquid ejected performs a waterproof detection work on the football that continuously collides between the inner parts of the lower cabin shell 21 and the upper cabin shell 22, detecting whether the continuously colliding football will generate cracks and cause a large amount of water to enter the interior of the football; a cavity structure is provided in the annular diversion basin 4; a plurality of liquid inlet grooves 401 structures communicating with the cavity structure are provided on the inner ring surface of the annular diversion basin 4; a liquid outlet pipe 41 communicating with the cavity structure is provided at the bottom of the annular diversion basin 4, and the liquid outlet pipe 41 is externally connected to the return port of the spray liquid circulating and conveying device. During the process of the sprayed spray liquid flowing downward along the surface of the annular diversion basin 4, the spray liquid will flow into the cavity structure of the annular diversion basin 4 through each liquid inlet groove 401 structure. Finally, the spray liquid in the cavity structure of the annular diversion basin 4 flows back to the externally connected spray liquid circulating and conveying device through the liquid outlet pipe 41; all the liquid inlet groove 401 structures on the annular diversion basin 4 are set as an inverted V-shaped structure that slopes downward to both sides. The inverted V-shaped liquid inlet groove 401 structure can not only slow down the downward flow speed of the spray liquid along the surface of the annular diversion basin 4, but also timely divert the spray liquid that fails to pass through the current liquid inlet groove 401 structure to the adjacent liquid inlet groove 401 structure, improving the collection efficiency of all the liquid inlet groove 401 structures of the annular diversion basin 4 for the spray liquid. Moreover, the retaining ring 43 blocking the outside of the annular partition 42 can also prevent the spray liquid from entering the circulating sandblaster 1, avoiding the phenomenon that a large amount of spray liquid flows through the sand return hopper 12 and enters the interior of the circulating sandblaster 1.On this basis, an electric heater for heating the lower friction plate 25 is installed in the lower cabin shell 21 of this embodiment. After the above-mentioned waterproof detection work is completed, the electric rotary machine 3 stops driving the striker plate 33 to rotate, and the football lands on the rotating table 31 and does not contact the lower friction plate 25. Then, the electric heater in the lower cabin shell 21 heats the lower friction plate 25 made of steel plate material. After the lower friction plate 25 made of steel plate material is heated by the electric heater, the temperature of the lower friction plate 25 itself rises rapidly. At the same time, during the process that the externally connected spray liquid circulation and transportation device continuously sprays the spray liquid between the lower cabin shell 21 and the upper cabin shell 22 through the nozzle 281 of the infusion pipe 28, the spray liquid contacting the high-temperature lower friction plate 25 will turn into high-temperature water vapor, filling a large amount of high-temperature water vapor between the lower cabin shell 21 and the upper cabin shell 22. Then, the electric heater stops heating the lower friction plate 25. After the lower friction plate 25 cools down to below 50 °C, the electric rotary machine 3 stops driving the striker plate 33 to rotate and continuously collide with the football, causing the football to continuously and violently collide again between the upper cabin shell 22 filled with water vapor, the lower cabin shell 21 and the striker plate 33, so as to detect whether the continuously colliding football will generate tiny cracks, resulting in a large amount of high-temperature water vapor entering the football interior, further strengthening the work intensity of the waterproof detection work on the football.

[0027] After the football waterproof detection work is completed, the operator takes out the football that has completed the waterproof detection work, then deflates it through the air nozzle of the football, and at the same time uses the carried humidity detector to detect the water content of the released gas. If the water vapor content in the gas released by the football is too high, it indicates that the football has cracks and water has entered its interior, thereby determining that the waterproof performance of the football is unqualified.

[0028] Embodiment 3 As Figures 1-7 shown, the difference between this embodiment and Embodiment 2 is that each striker plate 33 of this embodiment is fixedly connected with a brush 34. During the rotation of the brush 34 with the striker plate 33, the brush 34 closely adheres to the outer surface of the annular diversion basin 4 for cleaning work, and the brush 34 sweeps down the sand grains stuck in the liquid inlet groove 401 of the annular diversion basin 4, preventing a large number of liquid inlet grooves 401 in the annular diversion basin 4 from being blocked by sand grains, which may affect the normal backflow of the spray liquid.

[0029] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
