Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and in particular to a tire inflation and shaping device for inflating vulcanized tires. Background Technology

[0002] During the tire vulcanization process, after the tire vulcanization is completed, it needs to be placed in a shaping device for inflation, shaping, and cooling to prevent the vulcanized tire from deforming during the natural cooling and shaping process due to insufficient strength of the internal skeleton, which would affect the tire quality.

[0003] Existing tire inflation and shaping devices use hydraulic cylinders and power units to provide the pressure needed to prevent tire displacement due to inflation. However, this method is inconvenient to maintain, prone to hydraulic oil leaks and contamination, and suffers from insufficient precision in cylinder control when inflating and shaping tires of different sizes. Therefore, the applicant has developed a tire inflation and shaping device that uses electric drive to power the device, replacing the traditional hydraulic method. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tire inflation and shaping device for inflating vulcanized tires, including a frame, a first support member and a second support member fixedly mounted on the frame, a first chuck mechanism fixedly mounted on the first support member, and an electric drive mechanism fixedly mounted on the second support member; a second chuck mechanism connected to the electric drive mechanism, and a shaping station for tire inflation and shaping provided between the first chuck mechanism and the second chuck mechanism; and a transmission locking mechanism connected between the electric drive mechanism and the second chuck mechanism; wherein the electric drive mechanism drives the second chuck mechanism to approach the first chuck mechanism to fix and seal the tire, and during the tire inflation and shaping process, the transmission locking mechanism is used to prevent the second chuck mechanism from moving due to the force exerted by the tire inflation.

[0005] Preferably, the second chuck mechanism is disposed above or below the first chuck mechanism.

[0006] Preferably, the transmission locking mechanism includes a first transmission member and a second transmission member that are engaged with each other. The first transmission member has a power input end and a power output end. The power input end of the first transmission member is connected to the second transmission member, and the power output end of the first transmission member is connected to the second chuck mechanism. The first transmission member and the second transmission member are lockably configured.

[0007] Preferably, the first transmission component and the second transmission component are T-shaped lead screw and T-shaped nut structures, or worm gear and worm structure.

[0008] Preferably, the electric drive mechanism includes a servo motor and a first transmission mechanism driven by the servo motor.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, this utility model discloses a tire inflation and shaping device (hereinafter referred to as the tire inflation and shaping device) 1 for inflating vulcanized tires, including a frame 10, a first support member 11 fixedly mounted on the frame 10, a first chuck mechanism 20 fixedly mounted on the first support member 11; a second support member 12 fixedly mounted on the frame 10, the second support member 12 being opposite to the first support member 11, an electric drive mechanism 30 fixedly mounted on the second support member 12, and a second chuck mechanism 40 connected to the electric drive mechanism 30; wherein the first chuck mechanism 20 and the second chuck mechanism 40 are opposite to each other, and the first chuck mechanism 20 and the second chuck mechanism 40 are respectively... The device includes a tire inflation and shaping station W. The first chuck mechanism 20 and the second chuck mechanism 40 are used to fix the first end face 101 and the second end face 102 of the tire 100, respectively. The electric drive mechanism 30 drives the second chuck mechanism 40 closer to the first chuck mechanism 20, so that the first chuck mechanism 20 and the second chuck mechanism 40 fix and seal the first end face 101 and the second end face 102 of the tire. It also includes a transmission locking mechanism 50 connected between the electric drive mechanism 30 and the second chuck mechanism 40. During the tire inflation and shaping process, the transmission locking mechanism 50 prevents the second chuck mechanism 40 from moving due to the force exerted by the tire inflation. It should be noted that the tire inflation and shaping device of this invention also includes an air guide source (not shown) disposed on the first chuck mechanism 20 or the second chuck mechanism 40. The air guide source is used to ventilate the sealed tire 100, thereby inflating and shaping the tire.

[0022] The tire inflation device described above, through the electric drive mechanism 30 and the transmission locking mechanism 50, replaces the traditional hydraulic inflation and shaping device. When the sealed tire is inflated, the mechanical locking mechanism 50 prevents the second chuck mechanism 40 from moving away from the tire due to the expansion force applied by the tire. This ensures that the first chuck mechanism 20 and the second chuck mechanism 40 maintain a seal on the tire during inflation and shaping, preventing tire leakage and ensuring shaping quality. The mechanical locking method is more reliable and is not affected by pressure like the traditional hydraulic method. Furthermore, eliminating the hydraulic system effectively avoids the technical problem of hydraulic oil leakage polluting the environment.

[0023] It should be noted that the second chuck mechanism 40 described in this utility model can be disposed above or below the first chuck mechanism 20. For example... Figures 1 to 3 As shown, when the second chuck mechanism 40 is positioned above the first chuck mechanism 20, the tire to be inflated and shaped is first placed on the first chuck mechanism 20. The electric drive mechanism 30 then drives the second chuck mechanism 40 downwards towards the first chuck mechanism 20, bringing it into contact with the tire fixedly mounted on the first chuck mechanism 20, thus fixing and completely sealing the first end face 101 and the second end face 102 of the tire. When the second chuck mechanism 40 is positioned below the first chuck mechanism 20, the tire to be inflated and shaped is first placed on the second chuck mechanism 40. The electric drive mechanism 30 then drives the second chuck mechanism 40 upwards towards the first chuck mechanism 20, causing the tire mounted on the second chuck mechanism 40 to contact the first chuck mechanism 20, thus completely sealing the first end face 101 and the second end face 102 of the tire.

[0024] Preferably, the first chuck mechanism 20 of this utility model includes a detachable first chuck seat 21 and a first chuck 22. The first chuck 22 is contoured to the first end face 101 of the pneumatic tire, thereby better sealing the first end face 101 of the tire. The second chuck mechanism 40 includes a detachable second chuck seat 41 and a second chuck 42. The second chuck 42 is contoured to the second end face 102 of the pneumatic tire away from the first chuck. Through the aforementioned detachable connection of the first chuck mechanism 20 and the second chuck mechanism 40, when inflating and shaping tires of different specifications, especially for inflating and shaping tires of multiple varieties in small batches, only the corresponding first chuck 22 and second chuck 42 need to be replaced to quickly complete the shape change, improving shape change efficiency and better meeting production needs.

[0025] The transmission locking mechanism 50 of this utility model includes a first transmission member 51 and a second transmission member 52 engaged with each other. The first transmission member 51 has a power input end 511 and a power output end 512. The power input end 511 of the first transmission member is connected to the second transmission member 52, and the power output end 512 of the first transmission member is connected to the second chuck mechanism 40. The first transmission member 51 and the second transmission member 52 are lockable. The lockability of the first transmission member 51 and the second transmission member 52 means that when the power input end 511 of the first transmission member is subjected to a force transmitted by the second transmission member 52, the first transmission member 51 can move up and down. When the power output end 512 of the first transmission member is subjected to force, the first transmission member 51 remains stationary and cannot move up or down. That is, when the tire inflates and generates expansion force, the expansion force acts on the second chuck mechanism 40 and will not cause the first transmission member 51 to move.

[0026] Preferably, the first transmission component 51 and the second transmission component 52 of this invention can be a T-shaped lead screw and a T-shaped nut, or a worm gear and a worm, or other mechanical transmission structures with self-locking functions, thus combining transmission and self-locking functions. By setting a mechanical transmission structure with self-locking function, the power output end 512 of the first transmission component can be effectively and reliably prevented from moving under the action of force. Furthermore, the structure is simple and easy to use, maximizing the optimization of the overall device structure.

[0027] Preferably, the electric drive mechanism 30 includes a servo motor 31 and a first transmission mechanism 32 driven by the servo motor. The first transmission mechanism 32 can be a synchronous belt and synchronous pulley structure or a sprocket and chain structure. By replacing the traditional combination of hydraulic cylinder and hydraulic station with the servo motor 31, the control position is more precise, that is, the position of the second chuck mechanism 40 can be precisely controlled, thereby better inflating and shaping tires of different specifications; and it also effectively solves the problems of hydraulic oil leakage and environmental pollution caused by the traditional use of hydraulic cylinder and hydraulic station.

[0028] It should be noted that the tire inflation and shaping device of this utility model performs tire loading and unloading operations at a designated position, namely the initial tire loading and unloading position. After the tire has finished inflating, shaping, and cooling, the tire may stick to the first chuck mechanism 20 or the second chuck mechanism 40, thus preventing it from returning to the initial tire loading and unloading position. To solve the above technical problem, the tire inflation and shaping device of this utility model also includes a tire pushing device 60, which is disposed above the tire. The tire pushing device 60 includes a tire pushing drive source 61 and a tire pushing plate 62 driven by the tire pushing drive source 61. In use, the tire pushing drive source 61 drives the tire pushing plate 62 to extend, applying force to the tire located below the tire pushing plate 62, causing the tire to separate from the first chuck mechanism 20 or the second chuck mechanism 40, thereby allowing the tire to return to the initial tire loading and unloading position.

[0029] Appendix Figure 1 This is a first embodiment of the tire inflation and shaping device of the present invention. The tire inflation and shaping device 1 includes a frame 10, a first support member 11 fixedly mounted on the frame 10, a first chuck mechanism 20 fixedly mounted on the first support member 11, a second support member 12 fixedly mounted on the frame 10, the second support member 12 being opposite to the first support member 11, an electric drive mechanism 30 fixedly mounted on the second support member 12, and a second chuck mechanism 40 connected to the electric drive mechanism 30. The first chuck mechanism 20 and the second chuck mechanism 40 are opposite to each other, and a shaping station W for tire inflation and shaping is provided between the first chuck mechanism 20 and the second chuck mechanism 40. It also includes a transmission locking mechanism 50 disposed between the electric drive mechanism 30 and the second chuck mechanism 40.

[0030] To ensure that the second chuck mechanism 40 moves only up and down without rotating during its movement near the first chuck mechanism 20, the tire inflation and shaping device of this invention further includes a moving guide mechanism 70. Preferably, the moving guide mechanism 70 includes a guide sleeve 71 fixedly mounted on the second support member 12 and a guide shaft 72 fixedly mounted on the second chuck mechanism 40. The guide shaft 72 passes through the guide sleeve 71 and can move within the guide sleeve 71. Through the constraint of the guide shaft 72 and the first transmission member 51 in the transmission locking mechanism, the electric drive mechanism 30 drives the second chuck mechanism 40 to move only up and down without rotating during this process.

[0031] Appendix Figure 2 and 3This is a second embodiment of the tire inflation and shaping device of this utility model. The second embodiment is identical to the first embodiment in all other aspects, except for the specific structure of the moving guide mechanism. In this embodiment, the moving guide mechanism 70 includes a moving disk 73, and a slide rail 74 and a slider 75 connecting the moving disk 73 and the frame 10. The slider 75 can slide on the slide rail 74. The moving disk 73 is movably mounted on the frame 10 via the slide rail 74 and the slider 75. The transmission locking mechanism 50 and the second chuck mechanism 40 are connected via the moving disk 73; that is, the transmission locking mechanism 50 is fixedly mounted at one end of the moving disk 73, and the second chuck mechanism 40 is fixedly mounted at the other end of the moving disk 73. Through the moving guide mechanism 70, the expansion force generated during tire inflation and shaping is applied to the moving disk 73, preventing it from directly impacting the electric drive mechanism 30 and damaging it.

[0032] Appendix Figure 4 and 5 This is the third embodiment of the tire inflation and shaping device of this utility model. The third embodiment has the same structural principle as the second embodiment, but differs in that the tire inflation and shaping device includes two shaping stations, W1 and W2, for inflating and shaping the tire. Specifically, the tire inflation and shaping device includes a frame 10, a first support member 11 fixedly mounted on the frame 10, a first chuck mechanism 20A and a first chuck mechanism 20B respectively mounted on both sides of the first support member 11; second support members 12A and 12B fixedly mounted at both ends of the frame 10, the second support members 12A and 12B respectively being opposite to the first support member 11, an electric drive mechanism 30A fixedly mounted on the second support member 12A, a second chuck mechanism 40A driven by the electric drive mechanism 30A, and a shaping station W1 for inflating and shaping the tire located between the first chuck mechanism 20A and the second chuck mechanism 40A. The chuck mechanism 20A and the second chuck mechanism 40A are used to fix the sealed tire 100A. The system also includes a transmission locking mechanism 50A connected between the electric drive mechanism 30A and the second chuck mechanism 40A; an electric drive mechanism 30B fixedly mounted on the second support member 12B; and a second chuck mechanism 40B driven by the electric drive mechanism 30B. A shaping station W2 for inflating and shaping the tire is provided between the first chuck mechanism 20B and the second chuck mechanism 40B. The first chuck mechanism 20B and the second chuck mechanism 40B are used to fix the sealed tire 100B. The system also includes a transmission locking mechanism 50B connected between the electric drive mechanism 30B and the second chuck mechanism 40B. With the above-described tire inflation and shaping device, two tires can be inflated, shaped, and cooled simultaneously, greatly reducing the equipment's footprint. Of course, more than two shaping stations can be provided as needed.

[0033] In this embodiment, for the shaping station W1, the second chuck mechanism 40A is positioned below the first chuck mechanism 20A. In use, the tire 100A is placed on the second chuck mechanism 40A, and the electric drive mechanism 30A drives the second chuck mechanism 40A to move upwards, causing the tire 100A on the second chuck mechanism 40A to move upwards and fully contact the first chuck mechanism 20A, thus achieving fixation and sealing of the tire 100A. For the shaping station W2, the second chuck mechanism 40B is positioned above the first chuck mechanism 20B. In use, the tire 100B is placed on the first chuck mechanism 20B, and the electric drive mechanism 30B drives the second chuck mechanism 40B to move downwards, fully contacting the tire 100B, thus achieving fixation and sealing of the tire 100B.

[0034] Preferably, the tire pushing device 60A is disposed on the first chuck mechanism 20A, such that the tire pushing device 60A is located above the tire 100A, and after the tire is inflated and shaped, the tire 100A is separated from the first chuck mechanism 20A; the tire pushing device 60B is disposed on the movable disk 73B, such that the tire pushing device 60B is located above the tire 100B, and after the tire is inflated and shaped, the tire 100B is separated from the second chuck mechanism 40B.

[0035] The working principle of the tire inflation and shaping device of this utility model is as follows: A vulcanized tire 100 is moved onto the first chuck mechanism 20 or the second chuck mechanism 40 via a robotic arm or other transfer structure; the electric drive mechanism 30 drives the first transmission component 51 downwards, causing the second chuck mechanism 40 connected to it to contact the other end face of the tire, thus completely positioning and sealing the tire; or the electric drive mechanism 30 drives the first transmission component 51 upwards, causing the second chuck mechanism 40 connected to it and the tire mounted on the second chuck mechanism 40 to move upwards until the tire contacts the first chuck mechanism 20, thus completely positioning and sealing the tire; subsequently, the tire is moved onto the first chuck mechanism... The tire 100 is inflated by the air source on the first chuck mechanism 20 or the second chuck mechanism 40, allowing the tire 100 to inflate, expand, shape, and cool. After the tire 100 has finished inflating, shaping, and cooling, optionally, the tire is separated from the first chuck mechanism 20 by the tire pushing device 60, and the tire follows the second chuck mechanism 40 back to the initial tire placement position; or the tire 100 is separated from the second chuck mechanism 40 by the tire pushing device 60, keeping the tire in the position of the first chuck mechanism 20. Subsequently, the shaped tire placed in the initial tire placement position is moved to a designated position by a robotic arm or other transfer structure, and the inflation and shaping of the next tire is performed.

[0036] The tire inflation and shaping device of this utility model replaces the traditional hydraulic drive with an electric drive mechanism for inflating and shaping tires after vulcanization. This effectively solves the problem of hydraulic oil contamination and leakage caused by the hydraulic method. Furthermore, the electric drive allows for precise control of the second chuck mechanism's stopping position, making it more suitable for inflating and shaping tires of different sizes and offering greater versatility. By incorporating a transmission and locking mechanism that combines transmission and locking functions, it effectively prevents the expansion force generated by tire inflation from acting on the second chuck mechanism and causing it to move up and down, thus preventing air leakage. The locking is achieved through a mechanical structure, which is simple and easy to use. A moving guide mechanism with a movable disc connects the second chuck mechanism and the transmission and locking mechanism. When the second chuck mechanism is subjected to the expansion force of the tire, the force is distributed on the movable disc, thus preventing the transmission and locking mechanism from directly acting on the electric drive mechanism and causing damage.

[0037] The above description is only a partial embodiment of this application, and its purpose is to illustrate the technical concept and features of this application. Any equivalent changes or alternative technical solutions that can be easily conceived by those skilled in the art under the guidance of the technical content of this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
