[0031] The principle of the utility model

[0032] As Figure 3 shown is the separation state of the cooking cylinder 1 and the end cover 5, at this time, the raw materials and water and other chemical substances produced by the straw paper can be directly added into the cooking cylinder 1, the electric telescopic rod 3 is started, the connecting plate 4 and the end cover 5 are driven to move downwards until the clamping block 11 is inserted into the clamping groove 10, and the end cover 5 seals the cooking cylinder 1, as Figure 1 、 2 shown. In the state as Figure 1 、 2 shown, the electric telescopic rod 3 is continuously started, the connecting plate 4 is driven to move downwards, the connecting plate 4 compresses the spring 15, the spring 15 further generates pressure on the end cover 5, thereby increasing the sealing property of the end cover 5 and the cooking cylinder 1. At the same time, the sealing plate 19 continuously moves downwards to block the pressure relief hole 14. The heating block 9 is started to cook the raw material fibers in the cooking cylinder 1, and the rotating motor 13 is started to drive the rotating shaft 12 and the stirring blade to rotate, so that the raw materials are heated uniformly. The pressure sensor 7 and the temperature sensor 8 can monitor the temperature and pressure in the cooking cylinder 1 in real time, when pressure relief is needed, the electric telescopic rod 3 is started to drive the connecting plate 4 to move upwards by a small distance, so that the sealing plate 19 no longer blocks the pressure relief hole 14, at this time, the high-pressure gas in the cooking cylinder 1 can enter the pressure relief hole 14 through the adjusting hole 23, and finally escape from the pressure relief hole 14; after pressure relief is completed, the sealing plate 19 is immediately used to block the pressure relief hole 14. When cooking is completed, the raw material fibers wound on the rotating shaft 12 and the stirring blade need to be cleaned, the electric telescopic rod 3 is directly started to separate the end cover 5 from the cooking cylinder 1, and the rotating shaft 12 and the stirring blade are also moved out of the cooking cylinder 1, which is convenient for cleaning the raw material fibers.

[0033] The application can also adjust the pressure relief speed, as Figure 4 shown, the rotating plate 22 is driven to rotate by the operating rod 20, so that the adjusting hole 23 with different diameters is aligned with the pressure relief hole 14, therefore, when pressure relief, the larger the adjusting hole 23 aligned with the pressure relief hole 14, the faster the pressure relief speed, and the smaller the adjusting hole 23 aligned with the pressure relief hole 14, the slower the pressure relief speed.

[0034] The utility model and its implementation are described above, which is not restrictive, and the drawings shown are only one of the embodiments of the utility model, and the actual structure is not limited thereto. In summary, if the ordinary skilled person in the art is inspired, without departing from the creative purpose of the utility model, without creative design, the similar structure mode and embodiment of the technical scheme should belong to the protection scope of the utility model.
