For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0022] like Figure 1-3 As shown, this utility model provides a vacuum defoaming device for forming large tire blanks, including a main frame 1, a main housing 2, a hollow shaft 3, a forming device 4, a tail box 6, and a vacuum device 7. The main housing 2 and the tail box 6 are symmetrically fixed at both ends of the main frame 1. The hollow shaft 3 is rotatably connected to the middle of the main housing 2 and the tail box 6. The forming device 4 is placed in the middle of the hollow shaft 3. The vacuum device 7 is placed on the top of the tail box 6 and is connected to the hollow shaft 3.

[0023] This structural design makes the layout of the entire device reasonable and the connection between the components stable, which is conducive to improving the overall performance and service life of the device. At the same time, the symmetrical fixed connection design also helps to maintain the balance of the device during operation and reduce vibration and noise.

[0024] A filter box 8 is detachably installed in the middle of the vacuum device 7.

[0025] The removable filter box design facilitates daily maintenance and cleaning, effectively preventing dust and impurities from entering the vacuum device, thus ensuring the normal operation of the vacuum device 7, extending its service life, and also helping to improve the vacuuming effect and quality.

[0026] A pressure sensor 9 is installed on the top of the vacuum device 7, and the vacuum device 7 is connected to the hollow shaft 3 through a connecting pipe 10.

[0027] The installation of pressure sensor 9 enables real-time monitoring of pressure changes inside vacuum device 7, providing accurate data support for subsequent control. The connection method of connecting pipe 10 ensures air passage communication between vacuum device 7 and hollow shaft 3, which is beneficial for realizing the vacuuming function and improving the working efficiency of the entire device.

[0028] A PID controller 11 is installed in the middle of the connecting pipe 10, and the pressure sensor 9 and the PID controller 11 are centrally controlled by a circuit.

[0029] The installation of the PID controller 11 enables precise pressure control. In conjunction with the pressure sensor 9, it can automatically adjust relevant parameters according to the actual pressure conditions, thereby ensuring the stability of the vacuum level and improving the vacuuming effect and quality. At the same time, the centralized control method simplifies the operation process and improves the automation level of the device.

[0030] The hollow shaft 3 is equipped with a vacuum quick-release interface 12 at one end near the tail box 6, which can be detachably connected to the connecting pipe 10.

[0031] The design of the vacuum quick-release interface 12 makes the connection and disassembly between the connecting tube 10 and the hollow shaft 3 more convenient and quick, which helps to shorten the installation and commissioning time of the equipment, improve work efficiency, and also helps to quickly maintain and replace when needed, reduce downtime, and ensure the continuity of production.

[0032] The molding device 4 includes a clamping plate 5 and a rotating ring 13. The clamping plate 5 is installed in the middle of the molding device 4, and the rotating ring 13 is rotatably connected to the hollow shaft 3.

[0033] The structural design of the clamping disc 5 and the rotating ring 13 enables the forming device 4 to better adapt to the forming requirements of different specifications of blanks. The installation position of the clamping disc 5 and the rotation connection method of the rotating ring 13 are conducive to improving the stability and accuracy of the forming process, thereby ensuring the forming quality of the blank, and also helping to improve the versatility and applicability of the device.

[0034] The clamping plate 5 has multiple vacuum holes 15 in its center, and the rotating ring 13 has multiple vacuum branch pipes 14 installed in its center. Each vacuum branch pipe 14 has multiple air holes. When the rotating ring 13 rotates the vacuum branch pipe 14 to the vacuum hole 15, the hollow shaft 3 shown is connected to the vacuum branch pipe 14 through the vacuum hole 15. This design allows the vacuum system to more effectively vacuum and defoam the blank. The multiple vacuum holes 15 and vacuum branch pipes 14 increase the vacuuming area and efficiency. Simultaneously, the rotating connection method of the rotating ring 13 allows for flexible adjustment of the position of the vacuum branch pipe 14 according to actual needs, thereby achieving vacuuming of different parts and further improving the defoaming effect and the forming quality of the blank.
