The feeding device 2 receives tea raw materials through a feeding hopper. Tea raw materials are fed to the two vibration feeding mechanisms through the feeding hopper and are respectively fed to the two quantitative hoppers through the two vibration feeding mechanisms. When the tea raw materials in the quantitative hopper reach the preset weight, the temporary feeding can be realized by stopping the corresponding vibration feeding mechanism.

Secondly, the feeding device 2 feeds the receiving area through a feeding funnel 312.

After the tea raw material in the quantitative hopper reaches the preset weight, the tea raw material enters the material receiving area through the feeding funnel 312 by opening the lower turning plate of the quantitative hopper. The two quantitative hoppers can alternately supply tea raw materials required by one-time pressing for the material receiving area, and can also supply tea raw materials required by one-time pressing for the material receiving area in cooperation.

Thirdly, the pushing mechanism 32 is started, and the tea raw materials in the material receiving area are pushed to the tea steaming area through the pushing plate 321.

The pushing plate 321 is located at the side of the receiving area away from the tea steaming area at the initial position of the above step. After the pushing plate 321 pushes the tea raw material in the material receiving area to the tea steaming area, the feeding hole 311 is closed by the body of the pushing plate 321.

Fourthly, the steam generating device is started, an electromagnetic valve attached to the steam pipeline is opened, and steam is input into the tea steaming area through the steam hole 313 to complete tea steaming.

In this step, the head end of the die rod 331 is inserted into the opening of the first press hole 314 and the head end surface of the die rod 331 is disposed at the opening of the first press hole 314 on the side facing the nip. And the side surface of the die holder 341 facing the pressing main body 31 is attached to the side surface of the pressing main body 31. In this state, the movable stripper rod 333 is held by the return pressure spring 336 at the rear end thereof so that the movable stripper rod 333 is engaged with the front end surface of the press rod 331 to form a substantially hemispherical structure, and when the press base 341 moves to this position, the bottom surface of the press hole 344 is engaged with the front end surface of the fixed stripper rod 343 to form a substantially hemispherical structure, and the two hemispherical structures are oppositely disposed in the first press hole 314 and the second press hole 315, respectively.

And fifthly, starting the pushing mechanism 32, and pushing the steamed tea raw materials into the pressing area through the pushing plate 321.

After this step is completed, the pushing end face and the inner wall of the pressing main body 31 together make the pressing area form a cylindrical cavity.

Sixthly, the first driving unit 332 is started to push the die rod 331 toward the die holder 341.

During the process, the tea raw material in the pressing area is pushed into the pressing hole 344 along the transverse direction of the equipment by a hemispherical structure formed by the movable demoulding rod 333 and the end surface of the head end of the pressing rod 331, and is pressed in the pressing hole 344, so that the presetting is realized. Due to the two opposite hemispherical structures, the tea raw material is pressed into a compressed tea semi-finished product with a spherical (dragon pearl-shaped) structure.

After this step is completed, the tail end of the movable stripper rod 333 moves over the stopper rod 334 to the side of the stopper rod 334 facing the pressing body 31.

And seventhly, the limiting rod 334 is lifted by the lifting driving assembly 335 until the main body of the limiting rod 334 is positioned on the side of the tail end of the movable demoulding rod 333 departing from the position of the pressing main body 31. The first drive assembly 332 is actuated to push the die cylinder 331 in a direction away from the location of the die holder 341. Since the limiting rod 334 is located at the side of the tail end of the movable demolding rod 333 away from the pressing main body 31, that is, the process of pushing the pressing rod 331 makes the end surface of the tail end of the movable demolding rod 333 be supported by the main body of the limiting rod 334, and with the operation of the first driving component 332, the movable demolding rod 333 and the pressing rod 331 move relatively to separate the movable demolding rod 333 from the end surface of the head end of the pressing rod 331 (at this time, the reset pressure spring 336 is compressed), so as to separate the compressed tea semi-finished product pressed into the spherical (dragon ball-shaped) structure from the end surface of the head end of the pressing rod 331. Then, the first driving assembly 332 is started to drive the die rod 331 to move a certain distance towards the die holder 341, so that the movable die rod 333 is reset under the driving of the reset compression spring 336 for deformation and recovery.

Eighthly, the limiting rod 334 descends through the lifting driving assembly 335 until the horizontal position of the end face of the top end of the limiting rod 334 is positioned below the die pressing rod 331. The first drive assembly 332 is then actuated to push the die cylinder 331 in a direction away from the location of the die holder 341 until it returns to the position in step four.

At the same time, the second driving assembly 342 is actuated to drive the die holder 341 in a direction away from the location of the die rod 331. Due to the presence of the fixed mold release rod 343, the compressed tea semi-finished product is restricted from being separated from the press base 341 during the movement. After the semi-finished compressed tea leaves the die holder 341, the semi-finished compressed tea may fall to the inclined discharging table 11 under the influence of gravity, or may still be located on the end surface of the head end of the positioning and demolding rod 343.

After this step is completed, the second driving assembly 342 is activated to drive the die holder 341 to return to the position in step four.

Ninth, the discharging device 4 is started, the discharging push rod 41 is driven towards the area between the opening of the fixed demoulding rod 343 and the second pressing hole 315 located on the side of the pressing main body 31, and the pressed tea semi-finished product is determined to be separated from the end face of the head end of the fixed demoulding rod 343 by the way that the end of the discharging push rod 41 pushes the pressed tea semi-finished product, so that the pressed tea semi-finished product falls to the discharging inclined table 11.

Tenth, the semi-finished compressed tea is discharged along the discharging inclined table 11 in a rolling manner. Correspondingly, a conveying device such as a belt can be arranged in front of the discharge ramp 11 to cooperate with the discharge process.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
