[0002] In existing technologies, tire cord fabric is a crucial reinforcing material in tire manufacturing, typically composed of a fabric woven from high-strength fibers. It acts as a skeleton in the tire structure, primarily bearing loads, maintaining tire shape, and improving tire strength and durability.

[0003] Authorization announcement number "CN2597193Y" discloses a tire cord sleeve bonding machine, which relates to tire production machinery. One side of the frame is equipped with a cord roller, corresponding to the cord roller, and the other side of the frame is equipped with a cord sleeve bonding device. Each cord roller has a padding roller in front of it, and each padding roller has a cord conveying roller in front of it. A cord conveying frame is located in front of the cord conveying roller, and a feeding arm is hinged to the front of the cord conveying frame. The feeding arm has a feeding roller. During cord sleeve bonding, the machine can automatically separate the cord from the padding cloth and automatically feed the cord into the cord sleeve bonding device, eliminating the need for manual pulling of the cord onto the bonding roller. This reduces labor intensity and increases automation and efficiency. The bonding roller surface is equipped with high-pressure vent holes. High-pressure gas is input during cord sleeve removal and discharged through the high-pressure vent holes, which can inflate the cord sleeve, making cord sleeve removal easy. This machine is used to roll various tire cord sleeves.

[0004] The aforementioned novel material can bulge the cord sleeve, making it easy to remove the cord sleeve and roll it into various tire cord sleeves. However, during the cord alignment process, there are still problems such as low positioning accuracy, easy cord offset, and loose adhesion. In particular, when the cord is in contact with the curved surface of the tire inner tube, there is a lack of effective guiding and pressing structure. Utility Model Content

[0016] 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. Example 1

[0017] Please see Figures 1-4 The present invention provides the following technical solution: An automatic alignment device for aircraft tire cord fabric includes: Support plate 1; The guiding mechanism includes a sliding sleeve 2, a forward push rod 3, an outward expansion slide rod 4, an outward expansion limiting slide groove 5, an outward expansion limiting slider 6, an outward expansion plate 7, an outward expansion push rod 8, and a guiding circumferential surface 9. The sliding sleeve 2 is located on one side of the support plate 1. The forward push rod 3 is slidably connected inside the sliding sleeve 2. The outward expansion slide rod 4 is fixedly connected to one side of the forward push rod 3. The outward expansion limiting slide groove 5 is located on one side of the support plate 1. The outward expansion limiting slider 6 is slidably connected inside the outward expansion limiting slide groove 5. The outward expansion plate 7 is fixedly connected to one side of the outward expansion limiting slider 6. The outward expansion push rod 8 is rotatably connected to one side of the outward expansion plate 7 and one side of the outward expansion slide rod 4 via a rotating shaft. The guiding circumferential surface 9 is located on one side of the outward expansion plate 7.

[0018] In a specific embodiment of this utility model, a sliding sleeve 2 is formed on one end face of the support plate 1 to guide the forward push rod 3 to slide in a straight line; the forward push rod 3 is slidably connected inside the sliding sleeve 2 and can move back and forth under the action of external force; the outward expansion slide rod 4 is fixedly connected to one end of the forward push rod 3 and moves synchronously with it; the outward expansion limiting slide groove 5 is formed on the other side of the support plate 1 to limit the movement trajectory of the outward expansion limiting slider 6, so that it can only slide along a set path; the outward expansion limiting slider 6 is slidably connected in the outward expansion limiting slide groove 5 and serves as a guide component for the outward expansion plate 7; the outward expansion plate 7 is fixedly connected to one end of the outward expansion limiting slider 6 and moves with it to support and drive the guiding structure to move; the outward expansion push rod 8 is connected to a rotating shaft. The outer expansion plate 7 and the outer expansion slide rod 4 are respectively rotatably connected to one side of the outer expansion plate 7 and the other side of the outer expansion slide rod 4, forming a linkage structure. This transforms the linear motion of the forward push rod 3 into the lateral expansion or contraction of the outer expansion plate 7. The guide circumferential surface 9 is located on one side of the outer expansion plate 7. Its shape matches the curved surface of the tire inner tube and can contact the cord during the alignment process to achieve uniform pressing and position correction. When the device is running, the forward push rod 3 is pushed forward by the drive mechanism, which drives the outer expansion slide rod 4 forward as well. At the same time, the outer expansion push rod 8 changes angle through the rotating shaft, pushing the outer expansion plate 7 to expand outward, so that the guide circumferential surface 9 is close to the tire cord for alignment and bonding. When the push rod retracts, the outer expansion plate 7 contracts inward and detaches from the tire surface, completing one alignment cycle.

[0019] Please refer to the details. Figures 1-4 One side of the outer expansion plate 7 is fixedly connected to an inner tube cord guide plate 10, which is made of rubber and matches the shape of the tire inner tube.

[0020] In this embodiment, an inner tube cord guide plate 10 is also fixedly connected to one side of the outer expansion plate 7. This guide plate is made of rubber and has good flexibility and resilience. Its outline perfectly matches the surface shape of the tire inner tube, allowing it to fit tightly against the cord during the straightening process, providing a flexible pressing effect and avoiding material damage caused by rigid contact. At the same time, it improves the straightening accuracy and fit.

[0021] Please refer to the details. Figures 1-4 The lower end of the sliding sleeve 2 is fixedly connected to a support base 11, and the upper end of the support base 11 is fixedly connected to a cylinder sleeve 12. A telescopic cylinder 13 is fixedly connected inside the cylinder sleeve 12, and the extended end of the telescopic cylinder 13 is fixed to one side of the forward push rod 3.

[0022] In this embodiment: the lower end of the sliding sleeve 2 is fixedly connected to the support base 11, the upper end of the support base 11 is fixedly connected to the cylinder sleeve 12, the telescopic cylinder 13 is installed inside the cylinder sleeve 12 and fixedly connected to it; the extended end of the telescopic cylinder 13 is fixedly connected to one side end of the forward push rod 3. By controlling the extension and retraction of the cylinder, the forward push rod 3 is driven to slide back and forth in the sliding sleeve 2, thereby driving the entire guiding mechanism to complete the guiding action.

[0023] Please refer to the details. Figures 1-4 The lower end of the support base 11 is fixedly connected to the tire positioning slide rail 14, the upper end of the tire positioning slide rail 14 is slidably connected to the sliding base 15, and the upper end of the sliding base 15 is fixedly connected to the tire placement plate 16.

[0024] In this embodiment: a tire positioning slide rail 14 is fixedly connected to the lower end of the support base 11, a sliding base 15 is slidably connected to the upper end of the tire positioning slide rail 14, and a tire placement plate 16 is fixedly connected to the upper end of the sliding base 15. The tire placement plate 16 is used to support the aircraft tire to be assembled, and can slide along the tire positioning slide rail 14 via the sliding base 15 to allow the tire to accurately enter the guiding area, thereby completing the automatic guiding and bonding operation of the tire cord in conjunction with the guiding circumferential surface 9 and the inner tube cord guiding plate 10.

[0025] Please refer to the details. Figures 1-4 The sliding base 15 can be connected to an external drive mechanism to complete the sliding on the upper end of the tire positioning slide rail 14.

[0026] In this embodiment, the sliding base 15 can be connected to an external drive mechanism, such as a servo motor, hydraulic cylinder, or pneumatic push rod, to achieve precise sliding control of the sliding base 15 on the upper end of the tire positioning slide rail 14. Through programmed control, the sliding base 15 can automatically feed the tire into or out of the guide station according to the process flow, realizing fully automated operation and improving production cycle and equipment integration.

[0027] Please refer to the details. Figures 1-4 The upper end of the tire placement plate 16 is fixedly connected to a preliminary fixing groove 17, which matches the shape of the tire outer tire.

[0028] In this embodiment, a preliminary fixing groove 17 is fixedly connected to the upper end of the tire placement plate 16. The shape of the preliminary fixing groove 17 matches the outline of the tire outer casing and is used for preliminary positioning and stable support of the tire. This fixing groove can effectively prevent the tire from shifting or shaking during the alignment process, thereby ensuring the stability and consistency of the cord alignment and providing a reliable initial position reference for subsequent alignment actions.

[0029] The working principle and usage process of this utility model are as follows: A sliding sleeve 2 is formed on one side of the support plate 1 to guide the forward push rod 3 to slide in a straight line; the forward push rod 3 is slidably connected inside the sliding sleeve 2 and can move back and forth under external force; the outward expansion slide rod 4 is fixedly connected to one side of the forward push rod 3 and moves synchronously with it; the outward expansion limiting groove 5 is formed on the other side of the support plate 1 to limit the movement trajectory of the outward expansion limiting slider 6, so that it can only slide along a set path; the outward expansion limiting slider 6 is slidably connected in the outward expansion limiting groove 5, serving as a guide component for the outward expansion plate 7; the outward expansion plate 7 is fixedly connected to one side of the outward expansion limiting slider 6 and moves with it, serving to support and drive the guiding structure's movement; the outward expansion push rod 8 rotates... The shafts are rotatably connected to one side of the outer expansion plate 7 and one side of the outer expansion slide rod 4, forming a linkage structure that converts the linear motion of the forward push rod 3 into the lateral expansion or contraction of the outer expansion plate 7. The guide circumferential surface 9 is located on one side surface of the outer expansion plate 7, and its shape matches the curved surface of the tire inner tube. It can contact the cord during the straightening process to achieve uniform pressing and position correction. When the device is running, the forward push rod 3 is pushed forward under the action of the drive mechanism, driving the outer expansion slide rod 4 forward together. At the same time, the outer expansion push rod 8 changes angle through the rotating shaft, pushing the outer expansion plate 7 to expand outward, so that the guide circumferential surface 9 is close to the tire cord for straightening and bonding. When the push rod retracts, the outer expansion plate 7 contracts inward and detaches from the tire surface, completing one straightening cycle.
