Description

Technical Field

[0001] This utility model belongs to the field of football production technology, specifically relating to a football bladder inflation and shaping device. Background Technology

[0002] As a globally popular sporting item, the performance and durability of a football directly depend on the precision of its manufacturing process. A football typically consists of an inner bladder, a middle layer, and an outer skin. The inner bladder, as the core structure, must possess excellent airtightness and shape stability to ensure that the football maintains a standard spherical shape after inflation and retains uniform rebound characteristics over long-term use. Currently, football bladders are mostly made of polymer materials such as rubber or polyurethane, and their inflation and shaping process has a decisive impact on the final product's roundness, air pressure uniformity, and surface fit.

[0003] After inflating to the preset pressure with an air pump, the inner liner shape is judged by experience to see if it meets the standard. Then, subsequent patching or hot pressing is carried out. However, manual inflation and shaping are highly subjective and the air pressure control accuracy is low. This can easily lead to local over-expansion or under-pressure of the inner liner, causing sphere deformation or stress concentration at the joints, thus reducing the finished product qualification rate.

[0018] Reference Figure 1-3The image shows a soccer ball bladder inflation and shaping device, including a soccer ball bladder placement structure 1. A bladder limiting structure 2 is rotatably connected inside the soccer ball bladder placement structure 1. The number of bladder limiting structures 2 is set to four, arranged in a circular array inside the soccer ball bladder placement structure 1. An electric telescopic rod 3 is provided in the middle of the top of the soccer ball bladder placement structure 1. An inflation cone 4 is provided at the top of the electric telescopic rod 3. The soccer ball bladder is placed between the symmetrically arranged bladder limiting structures 2 on both sides. Then, the electric telescopic rod 3 is activated, causing the inflation cone 4 to insert into the inflation port of the soccer ball bladder. The inflation cone 4 is then connected to an air pump, which is activated to inflate the soccer ball bladder with gas. A football bladder placement structure 1 includes a positioning plate 101 and a lifting frame 105. Vertical bars 108 are provided at the bottom front and rear of the lifting frame 105, and inclined bars 109 are provided at the top front and rear of the lifting frame 105. Inclined bars 109 are provided at the bottom left and right sides of the lifting frame 105, and vertical bars 108 are provided at the top left and right sides of the lifting frame 105. The positioning plate 101 has mounting grooves 102 on its four sides. A transmission screw 103 is rotatably connected to the center of the bottom of the positioning plate 101. Guide shafts 104 are provided on both sides of the bottom of the positioning plate 101. A mating hole 106 is provided in the center of the lifting frame 105, and the mating hole 106 is connected to the transmission screw 103. 3. The lifting frame 105 is provided with sliding holes 107 on both sides. The sliding holes 107 are slidably connected to the guide shaft 104. A motor is provided inside the positioning plate 101. The output end of the motor is connected to the transmission screw 103. When the motor is started, the motor drives the transmission screw 103 to rotate. The transmission screw 103 drives the lifting frame 105 to rise and fall, so that the inner bladder limiting structure 2 at different positions contacts the vertical bar 108 and the inclined bar 109 at the corresponding positions. When the inner bladder limiting structure 2 contacts the vertical bar 108, the inner bladder limiting structure 2 unfolds outward. When the inner bladder limiting structure 2 contacts the inclined bar 109, the inner bladder limiting structure 2 moves inward to fit the football inner bladder, thereby fitting and shaping it.

[0019] Furthermore, in the above technical solution, the inner liner limiting structure 2 includes a rotating shaft 201, which is rotatably connected to the interior of the mounting groove 102. A planar spiral spring 202 is provided between the rotating shaft 201 and the mounting groove 102. A rotating bracket 203 is provided at the top and bottom of the rotating shaft 201. One end of the rotating bracket 203 at the bottom of the rotating shaft 201 is rotatably connected to a guide wheel 204. The guide wheel 204 is slidably connected to the vertical bar 108 and the inclined bar 109. One end of the rotating bracket 203 at the top of the rotating shaft 201 is rotatably connected to a rotating bar 205. The rotating bar 205 is rotatably connected to the rotating shaft 201. A torsion spring is provided between the frames 203. One end of the rotating bar 205 is provided with a fitting ring 206. A drive wheel 207 is rotatably connected to one side of the fitting ring 206. The guide wheel 204 slides on the outer wall of the vertical bar 108, the lifting frame 105 and the inclined bar 109. At the same time, the planar spiral spring 202 is used to reset the rotating shaft 201 during rotation. The two mutually symmetrically arranged drive wheels 207 are in the horizontal direction, and the other two drive wheels 207 are in the vertical direction. When the two drive wheels 207 come into contact with the football bladder, the drive wheels 207 are activated. The drive wheels 207 can inflate and shape the football bladder in different directions.
