Description

Technical Field

[0001] This application relates to the field of tire manufacturing technology, and in particular to a tire conveying device with a tire tread bonding and centering device. Background Technology

[0002] In the tire manufacturing industry, tread conveying equipment is a crucial component, directly impacting tire production efficiency and quality. As modern tire manufacturing demands ever-increasing precision and efficiency, the design of tread conveying equipment has become increasingly complex and specialized. Traditional equipment, with its simple mechanical structure, achieves basic tread conveying functions, playing a vital role in ensuring the fundamental tire manufacturing process. However, facing increasingly diverse and sophisticated production needs, existing technologies require further optimization to adapt to new challenges.

[0003] In practical applications, various conventional methods are commonly used in the industry to solve the stability problem during tire tread conveying. For example, a common method is to use fixed guide rails to limit the movement trajectory of the tire tread and ensure that it moves along a predetermined path; another method is to add multiple parallel rollers to form a conveyor belt, relying on the friction between the rollers to achieve smooth tire tread transmission.

[0004] However, the aforementioned conventional methods still have significant shortcomings when dealing with tire treads made of special materials (such as thin or soft treads). In particular, during the tread bonding process, fixed guide devices are prone to jamming due to tread curling and deformation, thus affecting bonding accuracy and production efficiency. This deficiency has become a key factor restricting efficient tread bonding, necessitating the development of more advanced solutions to overcome the limitations of existing technologies. Utility Model Content

[0005] In order to improve the bonding accuracy and production efficiency of tire treads, this utility model provides a tire tread conveying device with a tire tread bonding and centering device.

[0006] The present invention provides a tire conveying device with a tire tread bonding and centering device, which adopts the following technical solution:

[0007] A tire tread conveying device with a tread bonding and centering mechanism includes a conveyor frame, multiple sets of roller structures, a centering device, a drive device, and a conveying device. The multiple sets of roller structures are all connected to the conveyor frame and are evenly distributed along the conveyor frame. Each roller structure includes a roller shaft, rollers, and auxiliary rollers. Both ends of the roller shaft are connected to the conveyor frame. Each roller shaft has multiple rollers mounted on it, and the rollers are rotatably connected to the roller shaft. Multiple auxiliary rollers are provided on the surface of each roller, and these auxiliary rollers are spaced apart along the axial direction of the rollers. The rotation direction of the auxiliary rollers is perpendicular to the rotation direction of the rollers. The centering device includes multiple first limiting rods and multiple second limiting rods. The multiple first limiting rods are spaced apart along the tire tread transport direction. The first limiting rod is located in the gap between the two roller structures, and a plurality of second limiting rods are spaced apart along the transport direction of the tire tread. The first limiting rod and the second limiting rod are respectively located on both sides of the roller structure in the tire tread transport direction. The first limiting rod and the second limiting rod are both connected to the driving device to realize the centering and limiting of the first limiting rod and the second limiting rod on the tire tread. The conveying device includes a control component and a conveying component. The control component is connected to the top of the conveying frame, and the conveying component is located above the roller structure and connected to the control component. When the conveying component abuts against the tire tread, it is used to convey the tire tread.

[0008] By adopting the above technical solution, the cooperative design of the rollers and auxiliary wheels in the roller structure significantly improves the stability and guidance of tread conveying, reduces frictional damage between the tread and the equipment, and improves the quality and efficiency of tread conveying. At this time, the first and second limit rods in the centering device are respectively set on both sides of the tread conveying direction. Combined with the synergistic effect of the drive device, this ensures that the tread always remains on the ideal conveying path, reducing quality problems caused by positional deviations. In summary, the design of this conveying device enables the tread to receive uniform support and stable propulsion during conveying, improving the tread bonding accuracy and production efficiency.

[0009] Preferably, the centering device further includes a first moving plate and a second moving plate, a plurality of first limiting rods are connected to the first moving plate, a plurality of second limiting plates are connected to the second moving plate, and the first moving plate and the second moving plate are both connected to the driving device.

[0010] By adopting the above technical solution, the arrangement of the first and second moving plates enables the centralized connection of multiple first and second limiting rods, thereby achieving overall control of the centering device. Combined with the function of the drive device, the first moving plate can drive the first limiting rod to move, and the second moving plate can drive the second limiting rod to move, ensuring uniform force on both sides of the tire tread during transport and improving the accuracy and stability of centering and limiting. Furthermore, this structural design simplifies the assembly and debugging process of the centering device, enhancing the reliability and ease of maintenance of the equipment.

[0011] Preferably, the driving device includes a drive motor, a bidirectional lead screw, a first slider, and a second slider. The drive motor is connected to the conveyor frame, the bidirectional lead screw is rotatably connected to the conveyor frame, one end of the bidirectional lead screw is connected to the drive motor, the conveyor frame is connected to a mounting frame, the first slider and the second slider are both sleeved on the bidirectional lead screw, and the first slider and the second slider are both slidably connected to the mounting frame to realize the opposite movement of the first slider and the second slider, the first moving plate is connected to the first slider, and the second moving plate is connected to the second slider.

[0012] By adopting the above technical solution, the drive motor in the drive device drives the bidirectional lead screw to rotate, thereby realizing the opposite movement of the first and second sliders. This, in turn, drives the first and second limit rods to move synchronously, achieving precise centering and limiting of the tire tread. This design improves the stability during tire tread conveying, reduces the risk of tire tread misalignment, simplifies the centering adjustment process, and enhances the automation level and work efficiency of the equipment.

[0013] Preferably, the mounting bracket is provided with a first limiting part and two second limiting parts. The first limiting part is sleeved on the middle part of the bidirectional lead screw and is used to limit the distance between the first slider and the second slider. The two second limiting parts are respectively sleeved on both ends of the bidirectional lead screw.

[0014] By adopting the above technical solution, the first limiting part effectively controls the distance between the first slider and the second slider, effectively preventing them from getting too close, thereby ensuring the stability and accuracy of the centering device. The two second limiting parts are located at both ends of the bidirectional lead screw, further limiting the movement range of the first and second sliders, preventing them from disengaging from the bidirectional lead screw, and improving the overall structural reliability.

[0015] Preferably, a first sleeve is fitted onto the first limiting rod, and the first sleeve is rotatably connected to the first limiting rod.

[0016] By adopting the above technical solution, the first sleeve fitted on the first limiting rod can be rotatably connected to the first limiting rod, thereby reducing the friction between the tire tread and the first limiting rod during tire tread conveying, avoiding damage or deformation of the tire tread caused by friction, and improving the stability and quality of tire tread conveying.

[0017] Preferably, a second sleeve is fitted onto the second limiting rod, and the second sleeve is rotatably connected to the second limiting rod.

[0018] By adopting the above technical solution, the second sleeve is rotatably connected to the second limiting rod, which can reduce the friction between the tire tread and the second limiting rod during the conveying process, thereby avoiding damage to the tire tread surface due to friction and improving the conveying quality of the tire tread.

[0019] Preferably, the control assembly includes a fixed frame, a rotating rod, a support frame, a cylinder, and a connecting rod. The fixed frame is connected to the conveying frame. The rotating rod is horizontally positioned above the roller structure and is fixedly connected to the fixed frame. The support frame is sleeved on the rotating rod and rotatably connected to it. One end of the connecting rod is connected to the top of the support frame, and the other end is hinged to the cylinder. The cylinder is hinged to the fixed frame to achieve rotation of the support frame. The conveying assembly is connected to the support frame to move the conveying assembly closer to or further away from the roller structure.

[0020] By adopting the above technical solution, the cylinder drives the connecting rod to rotate the support frame around the rotating rod, thereby realizing the position adjustment of the conveying component relative to the roller structure. This design not only allows for flexible control of the distance between the conveying component and the roller structure, ensuring precise fit during tire tread conveying, but also effectively improves the adaptability of the equipment, meeting the conveying needs of different tire tread specifications, while simplifying the operation process and improving overall work efficiency.

[0021] Preferably, the conveying assembly includes a conveying roller and a conveying motor. The conveying roller is connected to the support frame, and the axis of the conveying roller is parallel to the axis of the roller shaft. The conveying motor is connected to the support frame, and the drive shaft of the conveying motor is connected to the conveying roller. When the conveying roller abuts against the tire tread, the conveying roller is positioned between the first limiting rod and the second limiting rod to realize the conveying of the tire tread.

[0022] By adopting the above technical solution, the conveying roller in the conveying assembly is connected to the support frame, and the axis of the conveying roller is parallel to the axis of the roller shaft, allowing the conveying roller to be stably positioned on the tire tread conveying equipment. The conveying motor is connected to the support frame, and its drive shaft is connected to the conveying roller, thereby achieving precise driving of the conveying roller. When the conveying roller comes into contact with the tire tread, it can effectively convey the tire tread, improving the stability and reliability of the conveying process.

[0023] In summary, this utility model has the following beneficial effects:

[0024] The coordinated design of the rollers and auxiliary wheels in the roller structure significantly improves the stability and guidance of tread conveying, reduces frictional damage between the tread and the equipment, and enhances the quality and efficiency of tread conveying. Meanwhile, the first and second limit rods in the centering device are respectively positioned on both sides of the tread conveying direction. Combined with the synergistic effect of the drive device, this ensures that the tread always remains on the ideal conveying path, reducing quality problems caused by positional deviations. In summary, the design of this conveying device allows the tread to receive uniform support and stable propulsion during conveying, improving tread bonding accuracy and production efficiency.

The first slider 63 is fixedly connected to the first moving plate 32, and the second slider 64 is fixedly connected to the second moving plate 34.

[0046] The drive motor 61 drives the bidirectional lead screw 62 to rotate, causing the first slider 63 and the second slider 64 to move towards each other, thereby realizing the opposite movement of the first moving plate 32 and the second moving plate 34.

The conveying motor 87 is fixedly connected to the support frame 83, and the shaft of the conveying roller 86 passes through the support frame 83 and is fixedly connected to the drive shaft of the conveying motor 87.

[0050] The tire tread is fed onto roller structure 2 by the previous process, and at this time the front end of the tire tread is transported to the preset position. The cylinder 84 is started, the drive shaft of the cylinder 84 retracts, the connecting rod 85 drives the support frame 83 to rotate, so that the support frame 83 drives the conveyor roller 86 to abut against the tire tread. Then the conveyor motor 87 is started, and the conveyor motor 87 drives the conveyor roller 86 to rotate. At this time, the conveyor roller 86 cooperates with the roller 22 to realize the conveying of the tire tread.

[0051] The operating principle of this application is as follows: After the tire tread is transported onto the roller structure 2, the drive motor 61 is started. The drive motor 61, through the bidirectional lead screw 62, causes the first slider 63 and the second slider 64 to move closer together. This, in turn, causes the first moving plate 32 to move the first limiting rod 31, and the second moving plate 34 to move the second limiting rod 33, thus achieving the mutual approach of the first limiting rod 31 and the second limiting rod 33, effectively solving the tire tread misalignment problem. Then, the conveying device 8 is started to transport the tire tread. This conveying equipment can adapt to the conveying needs of tires of different widths and materials.
