Description

Technical Field

[0001] This utility model relates to the field of ball production equipment technology, specifically a ball inner bladder installation device. Background Technology

[0002] The inner bladder is the core component of ball sports equipment. It is usually made of rubber, latex or polyurethane materials and is manufactured into a hollow spherical structure through hot pressing. The thickness of a standard football bladder is usually determined to a certain value and it needs to have a certain air pressure retention capacity. The surface has a reinforcing rib design to balance the force.

[0003] In the production of balls with inner bladders, such as soccer balls, the inner bladder is usually inserted into the outer skin before the outer skin is sewn on. However, the existing installation method usually involves manually inserting the inner bladder into the outer skin. During manual filling, it is easy to cause problems such as tangling and knotting due to forceful stuffing. This can easily lead to problems with the inner bladder during inflation. In the first inflation, the pressure on the entire inner bladder is often uneven, which usually requires refilling, which is quite inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a ball bladder installation device. This device reduces the degree of folding during installation, preventing the bladder from becoming tangled and requiring reinstallation. It solves the problem that in the production of balls with bladders, such as soccer balls, the bladder is typically inserted into the outer skin before being sewn on. Existing installation methods usually involve manually inserting the bladder into the outer skin. During manual insertion, forceful stuffing can easily lead to tangling and knotting, causing problems during inflation and uneven pressure on the bladder during the initial inflation, often requiring refilling, which is inconvenient.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a ball inner bladder installation device, including an installation frame, an outer skin expansion sleeve fixed to the outside of the installation frame, a sliding frame that can slide along its arrangement direction of the installation frame, and an inner bladder folding component whose position corresponds to the position of the outer skin expansion sleeve at the end of the sliding frame.

[0008] The inner liner folding assembly includes three fan-shaped folding pieces that can form a semicircle. The three fan-shaped folding pieces are rotatably connected by hinges. The two end fan-shaped folding pieces are fixedly provided with limiting components for limiting the position of the inner liner. Both end fan-shaped folding pieces are provided with limiting pieces for auxiliary limiting their own position. The middle fan-shaped folding piece is provided with an elastic limiting seat whose position can be limited by the limiting pieces.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the limiting piece is rhomboid in shape, and the limiting piece at the end, when folded, can enter the interior of the elastic limiting seat.

[0011] Furthermore, the elastic limiting seat includes a U-shaped limiting seat, and the inner wall of the limiting seat is fixedly installed with a limiting elastic piece for limiting the limiting piece.

[0012] Furthermore, the limiting component includes an inner liner connecting seat fixed to the outside of the fan-shaped folding piece, a reset elastic piece is fixedly installed inside the inner liner connecting seat, a pressing piece is fixedly connected to the end of the reset elastic piece and slidably connected to the inner wall of the inner liner connecting seat, and a drive rod extending into the inner liner connecting seat and driving the pressing piece to complete the pressing is inserted into the outside of the inner liner connecting seat.

[0013] Furthermore, the pressing piece is provided with an inclined groove on its outside, and the driving rod drives the pressing piece through the inclined groove. The inner liner connecting seat is provided with an opening on one side that can accommodate the folded inner liner. The pressing piece is positioned at the opening and clamps the inner liner by controlling the gap between the openings.

[0014] This utility model provides a ball-shaped inner liner installation device. By setting an outer skin expansion sleeve, when the inner liner needs to be installed, the outer skin ball sleeve can be opened by the outer skin expansion sleeve, and then the inner liner can be squeezed to flatten it and folded in half to form a semi-circle. At this time, the semi-circular inner liner and the unfolded semi-circular inner liner folding assembly can be overlapped. The end of the inner liner can be fixed by an elastic limiting assembly. After fixing, the inner liner can be folded by the fan-shaped folding pieces on both sides. During the folding process, the position of the limiting piece can be restricted by the elastic limiting seat. At this time, the folding assembly of the inner liner and the inner liner cannot be kept in a fan-shaped piece after folding. Pushing the sliding frame can insert the whole into the inner skin ball sleeve. Then, by moving the limiting piece, it can be disengaged from the elastic limiting seat, and the inner liner can be released by the limiting assembly. The inner liner folding assembly can be taken out while keeping the inner liner intact, thus completing the inner liner installation operation. It has the advantage that the folding degree of the inner liner installation process can be reduced to ensure that the inner liner will not need to be reinstalled due to tangling or knotting after insertion.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a ball inner bladder installation device, including an installation frame 1, an outer skin expansion sleeve 2 fixed to the outside of the installation frame 1, a sliding frame 3 that can slide along its arrangement direction, and an inner bladder folding component 4 whose position corresponds to the position of the outer skin expansion sleeve 2 at the end of the sliding frame 3.

[0022] The inner liner folding assembly 4 includes three fan-shaped folding pieces 41 that can form a semicircle. The three fan-shaped folding pieces 41 are rotatably connected by hinges. The two end fan-shaped folding pieces 41 are fixedly provided with limiting components 42 for limiting the position of the inner liner. The two end fan-shaped folding pieces 41 are each provided with limiting pieces 43 for auxiliary limiting of their own position. The middle fan-shaped folding piece 41 is provided with an elastic limiting seat 44 whose position can be limited by the limiting pieces 43.

[0023] In this embodiment, the limiting piece 43 is rhomboid in shape, and the limiting piece 43 can enter the interior of the elastic limiting seat 44 when the end fan-shaped folding piece 41 is folded.

[0024] The limiting piece 43 with this design can ensure better connection performance after the snap-fit ​​is completed, and prevent the limiting failure caused by the elasticity of the inner liner.

[0025] In this embodiment, the elastic limiting seat 44 includes a U-shaped limiting seat 441, and a limiting elastic sheet 442 for limiting the limiting sheet 43 is fixedly installed on the inner wall of the limiting seat 441.

[0026] Specifically, the difference in folding thickness formed by the two hinges should ensure that the three fan-shaped folding pieces 41 can be completely overlapped, while the position of the limiting elastic piece 442 in the two limiting seats 441 should be adapted to the position of the limiting piece 43.

[0027] In this embodiment, the limiting component 42 includes an inner liner connecting seat 421 fixed to the outside of the fan-shaped folding piece 41. A reset elastic piece 422 is fixedly installed inside the inner liner connecting seat 421. A pressing piece 423 that is slidably connected to the end of the reset elastic piece 422 and is connected to the inner wall of the inner liner connecting seat 421 is fixedly connected to the end of the reset elastic piece 422. A driving rod 424 that extends into the inner liner connecting seat 421 and drives the pressing piece 423 to complete the pressing is inserted into the outside of the inner liner connecting seat 421.

[0028] The side of the pressing plate 423 that contacts the inner liner should be provided with an anti-slip pad, and the outside of the anti-slip pad should be knurled. This design can effectively achieve better restriction of the inner liner position under compression.

[0029] In this embodiment, the pressing piece 423 is provided with an inclined groove on its outside. The driving rod 424 drives the pressing piece 423 through the inclined groove. The inner liner connecting seat 421 is provided with an opening on one side that can accommodate the folded inner liner. The pressing piece 423 is located at the opening and clamps the inner liner by controlling the gap of the opening.

[0030] The limiting component described above can be directly controlled by the drive rod 424, which in turn effectively restricts the inner liner through the pressing plate 423, thereby facilitating the fixation of the inner liner and making subsequent folding operations convenient. When it is necessary to release the fixation, simply pull the drive rod 424. At this time, under the action of the reset elastic plate 422, the pressing plate 423 will no longer press the inner liner, thereby releasing the connection with the inner liner.
