Two teams attack and defend against each other on the same rectangular field according to certain rules. After the football is produced, the air tightness of the football needs to be tested. The existing method for testing the air tightness of the football is to manually hold the football, find the inflation hole of the football, and use soapy water or other solutions to apply on the surface of the inflation hole to observe whether the football is leaking. However, since the football is prone to defects and weaknesses during the production process, the conventional method cannot detect whether it is leaking.

[0013] Beneficial Effects

[0014] The present invention provides an air tightness detection device for football production and processing, which has the following beneficial effects compared with the prior art:

[0015] 1. The user starts the motor A, and the screw fixed at the axis of the motor A starts to rotate at a constant speed. The slide board threadedly connected thereto starts to move linearly along the connection with the limit rod. The slide board starts to drive the connection plate fixed thereto to slide downward synchronously. The football clamped between the two positioning cylinders starts to enter the water. When the football enters the water, if there is a crack on it, bubbles can appear in the water under the action of the internal air pressure, thereby detecting the air tightness of the football. If no bubbles are observed in the water at this time, the user starts the motor, so that the main gear fixedly connected to its output shaft starts to rotate. At this time, multiple gears meshing around the main gear begin to rotate, and drive the screw rod fixed at its axis to rotate synchronously. At this time, the slide cylinder threaded on the screw rod begins to perform linear reciprocating motion along the connection between it and the positioning cylinder. At this time, the slide cylinder begins to push the push rod hinged to it, so that the push rod begins to push the pressure rod hinged to it, so that the pressure rod rotates at its hinge with the frame, and the arc plate fixed on it approaches the football. At this time, multiple arc plates begin to press the football intermittently in synchronization to press the football. At this time, if there are defects and weaknesses on the football, air leakage will occur, so that bubbles in the water can be observed to increase the accuracy of detection;

[0016] 2. The user pushes any positioning cylinder to make it move linearly along the connection between it and the guide rod, and starts to compress the spring fixedly connected to it, so that when the positioning cylinder stops being pushed, the spring can rebound and reset and push the positioning cylinder to slide synchronously. At this time, the two positioning cylinders cooperate with each other to clamp the football placed between them. At this time, part of the ball of the football fits into the positioning cylinder and contacts with the sphere on the inner wall of the positioning cylinder. At the same time, the sphere array is arranged on the inner wall of the positioning cylinder, which can effectively limit the ball. At the same time, when the motor drives the motor fixedly connected to its output shaft to start rotating, the shaft fixedly connected to the axis of the main gear starts to rotate synchronously, and drives the bevel gear A fixedly connected thereto to rotate at a uniform speed. The bevel gear A starts to drive the bevel gear B meshing with it to start rotating, so that the connecting rod fixedly connected to the axis of the bevel gear B starts to rotate synchronously. At this time, the roller fixedly connected to the connecting rod starts to rotate at a uniform speed, and the belt starts to rotate synchronously with the cooperation of the two rollers connected to it. At this time, the belt starts to push the football in contact with it, so that the football starts to rotate at a uniform speed under the limiting action of the two positioning cylinders. At the same time, since a ball is provided at the contact point between it and the positioning cylinder, the damping of its rotation can be effectively reduced. When the football rotates, the contact surface between it and the positioning cylinder can be adjusted, so as to avoid the positioning cylinder blocking the football and making it impossible to locate its leakage point.

[0017] 3. After detecting the leakage point, if the football is leaking, when the two positioning cylinders drive the football clamped therebetween to rise, start the motor B to make the guide rod A fixedly connected on its output shaft start to rotate, and make the transmission gear fixedly connected on the guide rod A start to rotate synchronously. At this time, the transmission gear begins to roll on it with the cooperation of the gear ring meshing with it, so that the slide frame begins to slide at a uniform speed along the arc-shaped slide rail at the connection between it and the frame. During this process, the user synchronously starts the fan in the bellows to generate airflow and blows the powder in the bellows onto the football through the leakage head fixedly connected thereon. At the same time, the slide frame keeps the motor in the starting state during its rotation, so that the football clamped between the two positioning cylinders rotates synchronously, so that the powder in the bellows can be evenly attached to the surface of the football. When the powder is attached to its surface, due to the leakage point on it, the powder cannot be attached to this area, thereby forming a marking point to locate the leakage point, which is convenient for the user to repair the leakage point.

When the football enters the water, if there is a crack on it, bubbles can appear in the water under the action of the internal air pressure, thereby detecting the air tightness of the football; if no bubbles can be observed in the water at this time, the user starts the motor 209, so that the main gear 208 fixedly connected to its output shaft starts to rotate, and this At this time, the multiple gears 207 meshingly connected around the main gear 208 begin to rotate, and drive the screw rod 206 fixedly connected at its axis to rotate synchronously. At this time, the slide cylinder 205 threadedly connected to the screw rod 206 begins to perform linear reciprocating motion along its connection with the positioning cylinder 201. At this time, the slide cylinder 205 begins to push the push rod 204 hinged to it, so that the push rod 204 begins to push the pressure rod 202 hinged to it, so that the pressure rod 202 rotates at its hinge with the frame 101, and the arc plate 203 fixedly connected thereto approaches the football. At this time, the multiple arc plates 203 begin to press the football intermittently in synchronization to pressurize the football. At this time, if there are defects and weaknesses on the football, air leakage will occur, so that bubbles in the water can be observed to increase the accuracy of detection.

[0031] Specifically, the adjustment component 3 includes a shaft 301, a bevel gear A302 and a bevel gear B303, one end of the shaft 301 is fixedly connected to the axis of the main gear 208, the other end of the shaft 301 is fixedly connected to the bevel gear A302, and the bevel gear B303 is meshed with the bevel gear A302.

[0034] Specifically, the connecting plate 308 is fixedly connected to the skateboard 3001, and the two sides of the skateboard 3001 are slidably connected to the limit rod 3003, and the limit rod 3003 is fixedly connected to the frame 101. The skateboard 3001 is threadedly connected to the screw 3002, and the screw 3002 is rotationally connected to the frame 101. One end of the screw 3002 is fixedly connected to the output shaft of the motor A3004, and the motor A3004 is fixedly connected to the frame 101.

[0035] In the embodiment of the present invention, the user pushes any positioning cylinder 201 to make it move linearly along the connection between it and the guide rod 307, and begins to compress the spring 309 fixedly connected thereto, so that when the pushing of the positioning cylinder 201 stops, the spring 309 can rebound and reset and push the positioning cylinder 201 to slide synchronously. At this time, the two positioning cylinders 201 cooperate with each other to clamp the football placed therebetween. At this time, part of the ball of the football fits into the positioning cylinder 201 and contacts the sphere on the inner wall of the positioning cylinder 201. At the same time, the sphere array is arranged on the inner wall of the positioning cylinder 201, which can effectively limit the ball. At the same time, when the motor 209 drives the motor 209 fixedly connected on its output shaft to start rotating, the shaft 301 fixedly connected to the axis of the main gear 208 starts to rotate synchronously, and drives the bevel gear fixedly connected thereon. Wheel A302 rotates at a constant speed, at which time bevel gear A302 begins to drive bevel gear B303 meshing with it to start rotating, so that connecting rod 304 fixedly connected at the axis of bevel gear B303 starts to rotate synchronously, and roller 305 fixedly connected to connecting rod 304 starts to rotate at a constant speed, and belt 306 starts to rotate synchronously with the cooperation of two rollers 305 connected to it for transmission, and belt 306 starts to push the football in contact with it, so that the football starts to rotate at a constant speed under the limiting action of two positioning cylinders 201, and at the same time, since a ball is provided at the contact point between it and positioning cylinder 201, the damping of its rotation can be effectively reduced, and the contact surface between it and positioning cylinder 201 can be adjusted when the football rotates, so as to avoid the positioning cylinder 201 blocking the football and making it impossible to locate its leakage point.

[0036] Specifically, the fixed-point component 4 includes a frame 401, a gear ring 402, a transmission gear 403 and a sliding frame 404.

[0037] Specifically, a guide rod A407 is fixedly connected at the axis of the transmission gear 403, and the guide rod A407 is rotatably connected to the sliding frame 404. One end of the guide rod A407 is fixedly connected to the output shaft of the motor B408, and the motor B408 is fixedly connected to the sliding frame 404. A bellows 405 is fixedly connected to the bottom of the sliding frame 404, and a plurality of drain heads 406 are symmetrically fixedly connected to the bellows 405.

[0038] In the embodiment of the present invention, after the leak point is detected, if the football is leaking, when the two positioning cylinders 201 drive the football held therebetween to rise, the motor B408 is started to rotate the guide rod A407 fixedly connected to its output shaft, and the transmission gear 403 fixedly connected to the guide rod A407 starts to rotate synchronously. At this time, the transmission gear 403 starts to roll on it in cooperation with the gear ring 402 meshing with it, so that the slide frame 404 starts to slide at a uniform speed along the arc-shaped slide rail at the connection between it and the frame 401. During this process, the user starts the synchronous rotation of the motor B408. The fan in the bellows 405 generates airflow and blows the powder in the bellows 405 onto the football through the leak head 406 fixedly connected thereto. At the same time, the sliding frame 404 keeps the motor 209 in a started state during its rotation, so that the football clamped between the two positioning cylinders 201 rotates synchronously, so that the powder in the bellows 405 can be evenly attached to the surface of the football. When the powder is attached to the surface, due to the leakage point on it, the powder cannot be attached to this area, thereby forming a marking point to locate the leakage point, which is convenient for the user to repair the leakage point.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0040] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0041] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0042] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.

[0043] The sliding connection referred to in the present application means that the component can slide along a linear trajectory, and the hinged connection referred to in the present application means that the component can rotate along an axial constraint.

[0044] In some cases, the sliding connection and hinge referred to in the present application may also be damped so that the components have the ability to maintain a desired position.
