[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0026] As Figure 1 shown, the ball skin turnover temporary ball skin restraint device includes a bottom plate 1, the upper end of the bottom plate 1 is fixed with two support plates 2, a box 3 capable of overturning is arranged between the two support plates 2, a tensioning assembly 4 is arranged on the box 3 to flatten and unfold the ball skin, which facilitates subsequent paint spraying and glue coating operations;

[0027] As Figure 2 shown, the tensioning assembly 4 includes two mounting plates 41 capable of synchronous reverse sliding on the box 3, one pressing plate 42 is arranged on each of the two mounting plates 41, the pressing plate 42 can press the end of the ball skin on the mounting plate 41, and by controlling the two mounting plates 41 to move away from each other, the ball skin can be flattened and unfolded;

[0028] In addition, in the embodiment, before paint spraying and glue coating, a part of the two ends of the ball skin is reserved as a clamping portion, after paint spraying and glue coating are completed, the clamping portion at the two ends of the ball skin is cut off and is pasted on the surface of the tire body, so that the ball skin paint surface and the glue coating surface are more fully ensured.

[0029] In the embodiment, as Figure 3 shown, two guide rods 421 are arranged on the pressing plate 42, the guide rods 421 penetrate through the mounting plate 41 and are slidably connected with the mounting plate 41, a circular table 422 is arranged at the end of the guide rod 421 away from the pressing plate 42, the diameter of the circular table 422 is greater than the diameter of the guide rod 421, a spring 43 is sleeved on the guide rod 421, the two ends of the spring 43 are fixed with the circular table 422 and the mounting plate 41 respectively, under the elastic force of the spring 43, the pressing plate 42 has a movement tendency of moving close to the mounting plate 41, and the ball skin can be pressed on the mounting plate 41;

[0030] Of course, the way to control the pressure plate 42 to press the ball skin onto the mounting plate 41 includes, but is not limited to, the spring 43 and other structures in this embodiment. In some embodiments, the pressure plate 42 can also be directly driven to move toward the mounting plate 41 by setting linear drive components such as cylinders and telescopic rods on the mounting plate 41, which can also achieve the goal of pressing the ball skin onto the mounting plate 41.

[0031] In this embodiment, both mounting plates 41 are slidably connected to the frame 3. Two first fixing plates 44 are provided on the frame 3, and a first lead screw 45 is rotatably connected between the two first fixing plates 44. Figure 4 As shown, the first lead screw 45 has a first external thread 451 and a second external thread 452 with opposite directions of rotation and equal pitch at both ends. The first external thread 451 and the second external thread 452 pass through the two mounting plates 41 and are threadedly connected to them. By setting a motor on one of the first fixed plates 44 to drive the first lead screw 45 to rotate, the synchronous reverse sliding of the two mounting plates 41 can be achieved.

[0032] Furthermore, in order to ensure the stability of the ball tension, the first lead screw 45 needs to have self-locking properties, that is, the thread helix angle of the first external thread 451 and the second external thread 452 is less than the equivalent friction angle.

[0033] Of course, the way to drive the two mounting plates 41 to slide synchronously in opposite directions includes, but is not limited to, the first lead screw 45 and other structures in this embodiment. In some embodiments, two cylinders can also be set on the block 3 to drive the two mounting plates 41 to slide synchronously in opposite directions respectively.

[0034] like Figure 5 As shown, a rotating shaft 31 is fixed at each end of the frame 3. The two rotating shafts 31 are coaxial with each other and are rotatably connected to the two support plates 2 respectively. In this embodiment, the frame 3 is driven to rotate around the rotating shaft 31 by setting a flipping drive component 5 on one of the support plates 2.

[0035] like Figure 6 As shown, the flipping drive assembly 5 includes a gear 51 fixed on one of the rotating shafts 31, a rack 52 slidably connected to the support plate 2 in the vertical direction, and the rack 52 meshing with the gear 51; a connecting plate 521 is provided on one side of the rack 52, and two second fixing plates 53 are provided on the support plate 2, with a second lead screw 54 rotatably connected between the two second fixing plates 53. The second lead screw 54 passes through the connecting plate 521 in the vertical direction and is threadedly connected to it. By setting a motor on one of the second fixing plates 53 to drive the second lead screw 54 to rotate, the lifting and lowering movement of the rack 52 can be controlled, thereby achieving the purpose of controlling the flipping of the box 3.

[0036] And, in order to ensure that the box 3 remains stable after being flipped, the second screw rod 54 needs to have self-locking, that is, the thread angle of the second screw rod 54 is smaller than the equivalent friction angle.

[0037] In other embodiments, the rotation of the rotating shaft 31 can also be directly driven by setting a motor on the support plate 52, so that the box 3 can be flipped around the rotating shaft 31; however, it is obvious that the motor-driven flipping of the box 3 is difficult to maintain the position of the box 3 stable, and the scheme of using the flipping driving assembly 5 to control the flipping is superior.

[0038] Working principle:

[0039] The box 3 between the two support plates 2 can be flipped, and the tensioning assembly 4 is arranged on the box 3, the tensioning assembly 4 is provided with two mounting plates 41 capable of synchronous reverse sliding, one pressing plate 42 is arranged on each of the two mounting plates 41, and the pressing plate 42 can be close to the mounting plate 41 and press the end of the ball skin on the mounting plate 41, by controlling the two mounting plates 41 away from each other, the ball skin can be flattened and unfolded, so as to avoid the ball skin being wrinkled and folded to affect the uniformity of paint spraying and glue coating. The flipping of the box 3 is driven by the flipping driving assembly 5 arranged on the support plate 2, and the self-locking of the second screw rod 54 in the flipping driving assembly 5 is used to ensure that the box 3 remains stable after being flipped, so as to facilitate paint spraying and glue coating.
