[0027] 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.

[0028] Example 1

[0029] Please see Figure 1-5 The present invention provides the following technical solution:

[0030] A tire forming drum, comprising:

[0031] The central shaft 6 has a central drum 7 on its circumferential surface;

[0032] Two drum shafts 4 are rotatably connected to both ends of the central shaft 6;

[0033] Two side drums 5 are detachably connected to the circumferential surfaces of two drum shafts 4;

[0034] Multiple sets of movable mechanisms are respectively located on the outer sides of the two drum shafts 4, used to drive the side drums 5 to move. Each set of movable mechanisms consists of a mounting groove 8 and an electric guide rail 9. The mounting groove 8 is opened on the circumferential surface of one of the drum shafts 4, and the slider 10 is slidably connected to the circumferential surface of the electric guide rail 9; and

[0035] Multiple disassembly and assembly mechanisms are provided. Each disassembly and assembly mechanism consists of a slider 10, a placement groove 18, a spring 13, a force plate 15, and a snap-fit ​​groove 17. The slider 10 is connected to the movable mechanism. The placement groove 18 is opened at the upper end of the slider 10. The spring 13 is fixedly connected to the lower inner wall of the placement groove 18. The force plate 15 is fixedly connected to the upper end of the spring 13. The snap-fit ​​groove 17 is opened on the circumferential surface of one of the side drums 5. The snap-fit ​​block 16 is fixedly connected to the upper end of the force plate 15, and the snap-fit ​​block 16 is movably snapped into the snap-fit ​​groove 17.

[0036] An external groove 19 is provided on one side of the inner wall of the placement groove 18, and a magnetic suction rod 20 is fixedly connected to one end of the force plate 15. An electromagnet 21 is provided on the circumferential surface of one of the drum shafts 4.

[0037] In a specific embodiment of this utility model, when it is necessary to shape the tire, rubber is adhered to the circumferential surface of the central drum 7, and the rubber is shaped to the required size by expanding the central drum 7. Then, the electric guide rail 9 is activated to slide the slider 10 on its circumferential surface, which drives the side drum 5 to move towards one end of the central drum 7, squeezing and pushing the rubber wrapped around the circumferential surface of the central drum 7 to shape it into a tire shape. When it is necessary to disassemble the side drum 5, the electric guide rail 9 also drives the slider 10 and the side drum 5 to move to the right. When the side drum 5 reaches the rightmost end, the magnetic attraction of the electromagnet 21 and the magnetic suction rod 20 can attract the magnetic suction rod 20 downward, thereby driving the force plate 15 and the locking block 16 to move downward. When the side drum 5 is disengaged from the locking mechanism 17, it can be detached for easy maintenance. When the side drum 5 needs to be installed, it is fitted onto the circumferential surface of the drum shaft 4. Then, the electromagnet 21 is turned off, at which point its magnetism ends. Then, through the elastic expansion of the spring 13, the force plate 15 and the locking block 16 are pushed upward again, and the locking block 16 is re-locked into the locking groove 17, making it easy to install the side drum 5. Through the above design, the disassembly and assembly of the side drum 5 is simpler and faster. It should be noted that the specific type of electric guide rail 9 and electromagnet 21 used shall be selected by those skilled in the art. The electric guide rail 9 and electromagnet 21 mentioned above are all existing technologies and will not be elaborated in this solution.

[0038] Please refer to the details. Figure 2 Vertical grooves 11 are provided between the inner walls on both sides of the placement groove 18. Both ends of the force plate 15 are fixedly connected to the vertical block 12. A telescopic rod 14 is fixedly connected to the lower inner wall of the placement groove 18, and a spring 13 is sleeved on the circumferential surface of the telescopic rod 14.

[0039] In this embodiment: when the force plate 15 moves, it will drive the vertical block 12 to slide in the vertical groove 11, which will improve the vertical sliding stability of the force plate 15. The telescopic rod 14 can prevent damage caused by the bending deformation of the spring 13.

[0040] Please refer to the details. Figure 2 One end of each of the two drum shafts 4 is connected to a side arm 1 by bolt thread, and the lower end of the two side arms 1 is connected to a base plate 2 by bolt thread. Multiple foot pads 3 are fixedly connected to the lower end of the base plate 2.

[0041] In this embodiment, multiple components can be supported by the side arm 1 and the base plate 2. The base plate 2 can be placed more stably by the foot pad 3. The side arm 1 can be disassembled by bolts, the base plate 2, and the drum shaft 4, making it easy to disassemble the side drum 5 from the circumferential surface of the drum shaft 4.

[0042] Working principle and usage process of this utility model:

[0043] When tire shaping is required, rubber is adhered to the circumferential surface of the central drum 7, and the rubber is shaped to the required size by expanding the central drum 7. Then, the electric guide rail 9 is activated to slide the slider 10 on its circumferential surface, which in turn moves the side drum 5 towards one end of the central drum 7, squeezing and pushing the rubber wrapped around the circumferential surface of the central drum 7 to shape it into a tire. When the side drum 5 needs to be disassembled, the electric guide rail 9 also moves the slider 10 and the side drum 5 to the right. When the side drum 5 reaches the rightmost end, the magnetic attraction of the electromagnet 21 and the magnetic rod 20 is used to disassemble it. The magnetic rod 20 can be attracted downwards, which in turn moves the force plate 15 and the locking block 16 downwards. When the locking block 16 and the locking groove 17 disengage, the side drum 5 can be disassembled for easy maintenance. When the side drum 5 needs to be installed, it is fitted onto the circumferential surface of the drum shaft 4. Then the electromagnet 21 is turned off, and its magnetism ends. Then, through the elastic expansion of the spring 13, the force plate 15 and the locking block 16 are pushed upwards again, and the locking block 16 is re-locked into the locking groove 17, making it easy to install the side drum 5.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
