An upper sealing plate 202 is rotatably installed on the outer wall of the inner pressure cylinder 203, and the upper sealing plate 202 is arranged in the outer cylinder 201. After the upper sealing plate 202 is rotated, the steam holes on the inner pressure cylinder 203 can be closed, and the inner wall of the inner pressure cylinder 203 can be in close contact with the outer wall of the die-casting cake 106. An inclined chamfer is arranged on the end of the inner pressure cylinder 203 close to the die-casting cake 106 to allow the die-casting cake 106 to enter the inner pressure cylinder 203, and a bottom opening is evenly arranged on the end of the inner pressure cylinder 203 away from the die-casting cake 106.

[0022] like Figures 2 to 4 and Figure 6 As shown, a closed arc plate 206 is fixedly installed at one end of the upper sealing plate 202 away from the die-casting cake 106, and a lower sealing plate 205 is fixedly installed at the other end of the closed arc plate 206. A plurality of closed arc plates 206 are arranged on the lower sealing plate 205. The lower sealing plate 205 is in close contact with the inner wall of the outer cylinder 201, and a plurality of rotating slide grooves 307 are fixedly installed at one end of the lower sealing plate 205 away from the upper sealing plate 202. The upper sealing plate 202, the closed arc plate 206, and the closed arc plate 206 are all arranged to close the steam holes and the bottom openings, and their purpose is to prevent a large amount of steam leakage.

[0023] like Figures 2 to 4 and Figure 6 As shown, a connecting rotating plate 209 is slidably installed on the rotating slide groove 307, and the connecting rotating plate 209 is in close contact with the inner wall of the lower sealing plate 205 in the initial state. A rotating shaft 306 is fixedly installed on the connecting rotating plate 209, and a fixed pressure plate 207 is fixedly installed on one end of the rotating shaft 306 close to the die-casting cake 106, and the fixed pressure plate 207 is in contact with the inner wall of the inner pressure cylinder 203. The fixed pressure plate 207 can cooperate with the die-casting cake 106 to press the softened tea leaves, and a plurality of bottom through holes are provided on the fixed pressure plate 207 to allow air flow to flow into the tea leaves.

[0024] like Figures 1 to 5As shown, a driving screw is provided on the rotating shaft 306, and a fixing nut 305 is threadedly installed on the driving screw, and a fixed stopper 308 is fixedly installed on the outer side of the fixing nut 305, and a lower bracket 108 is fixedly installed on the fixed stopper 308. The fixed stopper 308 is on the rotation track of the rotating slide 307, and will be stuck by the fixed stopper 308 when the rotating slide 307 rotates a predetermined angle. The lower bracket 108 is fixedly connected to the side bracket 107, and a main motor 301 is fixedly installed on the lower bracket 108, and a motor gear 302 is fixedly installed on the output shaft of the main motor 301. A rotating gear 303 is provided, and the rotating gear 303 is slidably connected to the rotating shaft 306, and the rotating gear 303 is rotatably connected to the lower bracket 108. When the rotating shaft 306 rotates, the fixing nut 305 is fixed, so the rotating shaft 306 will drive the rotating slide 307 to rotate around the axis of the rotating shaft 306, and at the same time, the rotating shaft 306 will drive the rotating slide 307 and the fixed pressure plate 207 to move away from the die-casting cake 106, so that the upper sealing plate 202 and the closed arc plate 206 can be rotated to block the steam hole and the bottom opening, and at the same time, the fixed pressure plate 207 can be moved outside the outer cylinder 201, so that it is convenient for users to take the pressed tea cakes.

[0025] Working principle: When the device is in use, tea leaves are placed in the outer cylinder 201, and then the hydraulic cylinder 105 is started to drive the die-casting cake 106 into the inner pressure cylinder 203. Note that there is no need to perform compression work at this time. The die-casting cake 106 will close the inner pressure cylinder 203, and the steam box 102 can be started at this time to allow the steam box 102 to generate a large amount of high-temperature steam, and the high-temperature steam is allowed to enter 20 through the gas pipe 104, and the steam in the outer cylinder 201 will enter the tea leaves in the inner pressure cylinder 203 through the steam hole, and the steam will also pass through The bottom opening enters the inner pressure cylinder 203 from the bottom through hole on the fixed pressure plate 207, so that the tea leaves can be prevented from having dead corners. The tea leaves softened by high-temperature steam will become very soft within a predetermined time, so that they can be pressed tightly. Then, the die-cast cake 106 is moved toward the fixed pressure plate 207, so that the tea cake can be formed. Then, the main motor 301 can be started to drive the rotating gear 303 to rotate, and the rotating gear 303 drives the rotating shaft 306 to rotate. When the rotating shaft 306 rotates, the rotating chute 307 is moved in Figure 5 When the rotating slide 307 rotates counterclockwise, it will contact the fixed stopper 308 after rotating a predetermined angle and be stuck. After the rotating slide 307 contacts the fixed stopper 308, the upper sealing plate 202 and the closed arc plate 206 will block the steam hole and the bottom opening on the inner pressure cylinder 203. When the rotating shaft 306 rotates, the fixed pressure plate 207 will also move to the outside of the inner pressure cylinder 203 to facilitate the user to take the tea cake.
