In this embodiment, it is preferably that the softening box 32 is composed of a bottom plate 321, a first partition plate 322, a second partition plate 323 and a top plate. The bottom plate 321 is fixedly connected to the workbench 1. Both the first partition plate 322 and the second partition plate 323 are detachably connected to the top of the bottom plate 321. There is a certain distance between the first partition plate 322 and the second partition plate 323. A communication port is provided on one side of the softening box 32, and the communication port penetrates the first partition plate 322;
[0033] Furthermore, a sealing block 324 is detachably connected between the first partition plate 322 and the second partition plate 323. The width of the sealing block 324 is equal to the width between the first partition plate 322 and the second partition plate 323. The output shaft of the propulsion cylinder 325 penetrates into the interior of the softening box 32, and the output shaft of the propulsion cylinder 325 is fixedly connected to a propulsion block 326. The propulsion block 326 is slidably connected to the interior of the softening box 32. The propulsion block 326 is located between the first partition plate 322 and the second partition plate 323.

The cavity of the softening tank 32 communicates with the outside through the discharge port 327. Furthermore, the stuffing rod 131 penetrates through the top plate and is located above the discharge port 327.
[0035] Since the space in the cavity of the softening tank 32 for accommodating tea leaves is limited, when the softening tank 32 needs to soften more tea leaves at one time, the first partition plate 322 and the second partition plate 323 are removed. After adjusting the distance between the first partition plate 322 and the second partition plate 323 to be wider, the first partition plate 322 and the second partition plate 323 are detachably connected to the workbench 1. The sealing block 324 is removed and replaced with a sealing block 324 having a wider width, so that the width of the sealing block 324 is equal to the width between the first partition plate 322 and the second partition plate 323. Then, the sealing block 324 is detachably connected between the first partition plate 322 and the second partition plate 323. The pushing block 326 is removed from the output shaft of the pushing cylinder 325 and replaced with a pushing block 326 having a wider width, so that the width of the pushing block 326 is equal to the width between the first partition plate 322 and the second partition plate 323. Then, the pushing block 326 is detachably connected to the output shaft of the pushing cylinder 325. The top plate is removed from the first partition plate 322 and the second partition plate 323 and replaced with a top plate having a wider width, so that the width of the top plate can cover the first partition plate 322 and the second partition plate 323. Then, the top plate is detachably connected to the first partition plate 322 and the second partition plate 323, thereby increasing the volume of the inner cavity of the softening tank 32.

The filter screen 328 can prevent the tea leaves in the softening tank 32 from entering the gas guide seat 33, and the steam in the gas guide seat 33 can pass through the filter screen 328 and enter the softening tank 32.
[0037] The softening mechanism 3 further includes a feeding box 31, and the feeding box 31 is fixedly connected to the bottom plate 321; a feeding plate 312 is slidably connected inside the feeding box 31, a feeding cylinder 311 is provided on the bottom plate 321, the output shaft of the feeding cylinder 311 penetrates into the interior of the feeding box 31 from one side of the feeding box 31, the output shaft of the feeding cylinder 311 is fixedly connected to the feeding plate 312, and the other side of the feeding box 31 is communicated with the softening box 32 through a communication port; a feeding port 313 is opened at the top of the feeding box 31, the interior of the feeding box 31 is communicated with the outside through the feeding port 313, and the discharging area 2 is located above the feeding port 313; the weighing mechanism 2 sequentially pours each portion of tea into the interior of the feeding box 31 from the feeding port 313 at regular intervals.
[0038] The output shaft of the feeding cylinder 311 pushes the feeding plate 312 to slide from one side inside the feeding box 31 to the other side inside the feeding box 31. The feeding plate 312 pushes the tea inside the feeding box 31 into the softening box 32 through the communication port. Moreover, the feeding plate 312 blocks the communication port. The output shaft of the stuffing cylinder 13 pushes the stuffing rod 131 to slide inside the softening box 32, so that the stuffing rod 131 blocks the discharging port 327 to prevent the tea inside the softening box 32 from falling out of the discharging port 327. The air guide seat 33 introduces steam into the softening box 32 to steam-soften the tea; after the tea is steamed and softened, the output shaft of the stuffing cylinder 13 pulls the stuffing rod 131 away from the discharging port 327. The output shaft of the pushing cylinder 325 pushes the pushing plate to slide inside the softening box 32 close to the discharging port 327, so as to push the tea inside the softening box 32 towards the discharging port 327. The output shaft of the stuffing cylinder 13 pushes the stuffing rod 131 close to the discharging port 327 to push the tea out of the discharging port 327. After the tea in the softening box 32 is discharged, the output shaft of the feeding cylinder 311 pulls the feeding plate 312 to slide back to its original position, and the feeding box 31 vacates space for feeding the next portion of tea. The output shaft of the pushing cylinder 325 pulls the pushing block 326 to slide back to its original position.

The bottom of the sliding seat 41 is slidably connected to the slide rail 112, and the bottom of the mold 42 is detachably connected to the top of the sliding seat 41. A blanking channel 411 is provided on the sliding seat 41, and the blanking channel 411 is close to the top of the mold 42; a blanking support 412 extends from the bottom of the sliding seat 41, and the blanking support 412 passes through the sliding groove 111, and the blanking support 412 is located inside the sliding groove 111; a traveling cylinder 14 is provided on the workbench 1, the output shaft of the traveling cylinder 14 is parallel to the output shaft of the slide rail 112, and the output shaft of the traveling cylinder 14 is fixedly connected to the sliding seat 41;
[0041] The top of the mold 42 is lower than the bottom of the bottom plate 321, preventing the mold 42 from hitting the bottom plate 321. The output shaft of the traveling cylinder 14 pulls the sliding seat 41 to slide on the slide rail 112, moving the mold 42 below the discharge port 327 so that the mold 42 can receive the tea leaves pushed out from the discharge port 327.

The output shaft of the pressing cylinder 43 penetrates the bearing support 12. A sliding plate 121 is slidably connected to the bearing support 12. The two sides of the sliding plate 121 are respectively slidably connected to two optical rods. The output shaft of the pressing cylinder 43 is fixedly connected to the top of the sliding plate 121. An upper mold 431 is provided on the output shaft of the pressing cylinder 43. The upper mold 431 is detachably connected to the bottom of the sliding plate 121.
[0044] The output shaft of the traveling cylinder 14 pushes the sliding seat 41 to slide on the slide rail 112, moving the mold 42 below the upper mold 431, bringing the upper mold 431 close to the top of the mold 42. The output shaft of the pressing cylinder 43 pushes the sliding plate 121 to slide down on the optical rods, causing the upper mold 431 to penetrate into the mold 42 so that the upper mold 431 and the lower mold 414 squeeze the tea leaves to form a tea cake. When the pressing mechanism 4 presses the tea cake, the softening mechanism 3 operates simultaneously to soften the tea leaves. The output shaft of the pressing cylinder 43 pulls the sliding plate 121 to reset. The output shaft of the blanking cylinder 413 pushes the lower mold 414 to slide up inside the mold 42, pushing the tea cake inside the mold 42 out of the mold 42. The output shaft of the traveling cylinder 14 pulls the sliding seat 41 to slide on the slide rail 112.
