[0004] The tablet pressing device in the prior art is used in the process such as Figure 8 As shown, a material trough 104 is provided in the lower mold 102, a top block 105 is slidably connected in the material trough 104, and a pressing rod 110 is slidably connected to the top of the material trough 104. When the pressing rod 110 is pressed into the material trough 104, part of the powder raw material 300 in the material trough 104 will be splashed out from the material trough 104, and the splashing direction is as shown in FIG. Figure 8 As shown, the part of the powder raw material sputtered out not only causes dust pollution to the production environment, but also the part of the overflowed powder raw material will fall back onto the lower mold, which will affect the collection of the formed candy tablets. After the candy tablets are pressed and formed, the tablet candies are ejected from the material trough by moving the top block upward, and then the tablet candies are moved to the collection frame. Since the sputtered powder raw material falls back onto the lower mold, this part of the powder raw material will also be moved to the collection frame and mixed with the candies, and it will need to be separated later, which is very troublesome.

[0019] The present invention also provides a tableting method for tableting candies rich in cassia seeds and dried wolfberries, using the tableting device described above, comprising the following steps:

[0020] Step 1: Start the hydraulic cylinder 2 to drive the disc 2, the pressure rod, the cylinder 1, and the piston rod to move downward. When the annular cover fits the top of the lower mold, the hydraulic cylinder 2 continues to extend, which will drive the pressure rod to continue to move downward.

[0021] Step 2: When the pressure rod continues to move downward, the piston rod 1 will move upward in the cylinder body 1, thereby driving the piston 1 to move upward in the cylinder body 1, and the air in the chamber 2 is discharged from the air hole. At this time, the chamber 1 is evacuated to a negative pressure. At this time, the one-way valve 1 and the one-way valve 2 are opened, while the one-way valve 3 and the one-way valve 4 are closed, so that the air in the chamber 3 is evacuated from the conduit 3, the collecting barrel, and the connecting pipe 1 to the chamber 1, and a negative pressure is formed in the chamber 3;

[0022] Step 3: When the cover body moves downward and contacts the annular sleeve, the pressing rod is not embedded in the material trough, and then the cover body continues to move downward to squeeze the annular sleeve to move into the annular groove, and then the pressing rod is embedded in the material trough for tableting. During tableting, the sputtered raw material powder is sucked into the inner cavity 2 by the negative pressure chamber 3;

[0023] Step 4: After the candy tableting is completed, the hydraulic cylinder 2 contracts and drives the disc 2 and the pressure rod to move upward. At this time, the piston is driven downward under the rebound force of the spring 1. At this time, the one-way valve 1 and the one-way valve 2 are closed, while the one-way valve 4 is opened and the one-way valve 5 is closed. At this time, the air in the chamber 1 is discharged into the tube body 1, thereby driving the piston 3 and the piston rod 3 to move downward. When the piston rod 3 moves downward, it drives the connecting rod to rotate. When the connecting rod rotates, it drives the piston rod 2 and the piston 2 to move, and the collecting cylinder is pumped into a negative pressure. At this time, the one-way valve 3 and the one-way valve 6 are opened. After the one-way valve 3 is opened, the powder raw material in the inner cavity 2 is sucked into the collecting cylinder. After the one-way valve 6 is opened, the suction pipe is pumped into a negative pressure through the connecting pipe 3, so that the powder raw material at the edge of the material trough is pumped into the collecting cylinder through the suction pipe, the cavity, the conduit 1, and the connecting pipe 3.

[0024] Beneficial effects of the present invention:

[0025] 1. When piston rod 1 moves upward in cylinder body 1, it drives piston 1 to move upward in cylinder body 1, and chamber 1 is evacuated to form negative pressure. At this time, one-way valve 1 and one-way valve 2 are opened, while one-way valve 3 and one-way valve 4 are closed, so that the air in chamber 3 is evacuated from conduit 3, collecting barrel and connecting pipe 1 to chamber 1, and negative pressure is formed in chamber 3. When the pressing rod is embedded in the material trough for tableting, the sputtered raw material powder is evacuated into inner chamber 2 by negative pressure chamber 3 during tableting. Due to the obstruction of filter cloth 1, the powder raw material is retained in inner chamber 2.

[0026] 2. When the candy tableting is completed, when the hydraulic cylinder 2 contracts, the piston is driven to move downward under the rebound force of the spring 1. At this time, the one-way valve 1 and the one-way valve 2 are closed, while the one-way valve 4 is opened and the one-way valve 5 is closed. At this time, the air in the chamber 1 is discharged into the tube body 1, thereby driving the piston 3 and the piston rod 3 to move downward, and driving the piston 2 to move, and the collecting cylinder is pumped into a negative pressure. At this time, the one-way valve 3 is opened, so that the powder raw material in the inner chamber 2 is sucked into the collecting cylinder, avoiding the powder raw material being blocked on the filter cloth 1 when the collecting cylinder is subsequently pumped into a negative pressure.

[0027] 3. When negative pressure is created in the collecting cylinder, the one-way valve 6 is also opened. When some powder raw materials that have not been sucked into the inner cavity 2 fall onto the lower mold, the one-way valve 6 is opened and the suction tube is sucked into negative pressure through the connecting pipe 3, thereby sucking the powder raw materials on the lower mold into the collecting cylinder, so that the powder raw materials can be collected more fully.

At this time, the one-way valve 4 228 and the one-way valve 6 230 are closed, and the one-way valve 5 229 is opened, so that the air in the tube body 1 216 is discharged from the exhaust pipe 218, so that the piston 3 223 returns to its original position, and then drives the piston 2 219 to move to its original position, and the next powder raw material collection can be carried out.

[0052] Embodiment 2

[0053] Based on the first embodiment, a method for tableting candies rich in cassia seeds and dried wolfberries is provided, which specifically comprises the following steps:

[0054] Step 1: Start the hydraulic cylinder 109 to drive the disc 108, the pressure rod 110, the cylinder 201, and the piston rod 204 to move downward. When the annular cover 2081 and the top of the lower mold 102 are in contact, the hydraulic cylinder 109 continues to extend, which drives the pressure rod 110 to continue to move downward.

[0055] Step 2: When the pressure rod 110 continues to move downward, the piston rod 1 204 will move upward in the cylinder body 1 201, thereby driving the piston 1 202 to move upward in the cylinder body 1 201, and the air in the chamber 2 2052 will be discharged from the air hole 234. At this time, the chamber 1 2051 is evacuated to a negative pressure. At this time, the one-way valve 1 225 and the one-way valve 226 are opened, while the one-way valve 3 227 and the one-way valve 4 228 are closed, so that the air in the chamber 3 211 is evacuated from the conduit 3 212, the collecting barrel 2071, and the connecting pipe 1 206 to the chamber 1 2051, and a negative pressure is formed in the chamber 3 211;

[0056] Step 3: When the cover body 209 moves downward and contacts the annular sleeve 232, the pressing rod 110 is not embedded in the material trough 104, and then the cover body 209 continues to move downward to squeeze the annular sleeve 232 to move into the annular groove 231, and then the pressing rod 110 is embedded in the material trough 104 for tableting. During tableting, the sputtered raw material powder is sucked into the inner cavity 2074 by the negative pressure chamber 3 211;

[0057] Step 4: After the candy tableting is completed, the hydraulic cylinder 2 109 contracts to drive the disc 2 108 and the pressure rod 110 to move upward. At this time, the piston 1 202 is driven downward under the rebound force of the spring 1 235. At this time, the one-way valve 1 225 and the one-way valve 226 are closed, and the one-way valve 4 228 is opened, and the one-way valve 5 229 is closed. At this time, the air in the chamber 1 2051 is discharged into the tube body 1 216, thereby driving the piston 3 223 and the piston rod 3 222 to move downward. When the piston rod 3 222 moves downward, it drives the connecting rod 221 to rotate, and the connecting rod 221 rotates. When it moves, it drives the piston rod 220 and the piston 219 to move, and the collecting tube 214 is pumped into a negative pressure. At this time, the one-way valve 3 227 and the one-way valve 6 230 are opened. After the one-way valve 3 227 is opened, the powder material in the inner cavity 2074 is sucked into the collecting tube 214. After the one-way valve 6 230 is opened, the suction pipe 2083 is pumped into a negative pressure through the connecting pipe 3 2086, so that the powder material at the edge of the material trough 104 is pumped into the collecting tube 214 through the suction pipe 2083, the cavity 2082, the conduit 1 2084, and the connecting pipe 3 2086.
