[0060] Specifically, the partial raw materials refer to the raw materials required for the preparation of the biological tablets, such as malt dextrin, detoxifying agents, slow-release oxidizing agents and biological growth promoters, which are not limited in particular and can be determined according to the requirements of use.

[0061] Specifically, the control module is, for example, a CPU or a PLC, which is not limited in particular and only needs to meet the requirement of outputting the corresponding determination results according to the input parameters.

[0063] Specifically, the second detection module is, for example, a weight meter and a hardness meter, which is not limited in particular and is used to obtain the tablet density and the hardness from the surface to the core of the tablet.

[0064] Specifically, the cooling part 2 is, for example, a belt conveyor or a belt conveyor provided with a fan, which is not limited in particular and is used to cool the conditioned materials.

[0065] Specifically, the upper tablet pressing module 42 includes a first rotating disc 4201 provided with a plurality of upper punches 4202 corresponding to the forming holes 4101 of the forming die 41, an upper reset spring 4203 arranged between each upper punch 4202 and an upper mounting hole 4204 of the first rotating disc 4201, a first arc-shaped loading block 4205 arranged to load each upper punch 4202 during the rotation of the first rotating disc 4201 to complete the tablet pressing, an upper mounting seat 4206 arranged to fix the first arc-shaped loading block 4205, and a hydraulic column 4207 arranged circumferentially on the upper mounting seat 4206 to control the movement of the upper mounting seat 4206 along the vertical direction,

[0066] The lower tablet pressing module 43 includes a second rotating disc 4302 provided with a plurality of lower punches 4301 corresponding to the forming holes 4101 of the forming die 41, a lower reset spring 4305 arranged between each lower punch 4301 and a lower mounting hole of the second rotating disc 4302, and a second arc-shaped loading block 4304 arranged to load each lower punch 4301 during the rotation of the second rotating disc 4302 to eject the completed tablet.

[0067] The projection of the first arc-shaped loading block 4205 and the second arc-shaped loading block 4304 on the plane does not coincide.

[0068] Specifically, the upper punch 4202 completes the preparation action based on the contact with the arc-shaped edge of the first arc-shaped loading block 4205 and the upper reset spring.

[0069] Specifically, the tablet collecting module comprises a tablet scraper 4401 arranged on the upper end surface of the forming die 41 and a material falling groove 4402 arranged at the end of the tablet scraper; the output end of the material falling groove is provided with a collecting frame 4403.

[0070] Specifically, the control module determines whether the preparation of the raw material meets the standard according to the average particle size of the raw material after mixing.

[0071] If the average particle size of the raw material after mixing is less than the first preset average particle size, the control module determines that the preparation of the raw material does not meet the standard and increases the steam flow of each steam delivery pipe 104 of the preparation part 1, and the increase of the steam flow of each steam delivery pipe 104 of the preparation part 1 is calculated by the following formula:

[0072]

[0073] In the formula, L' represents the steam flow of the steam delivery pipe 104 after the increase, L represents the current steam flow of the steam delivery pipe 104, represents the first preset average particle size, represents the average particle size of the raw material, and λ represents the steam flow adjustment coefficient, and λ is set to be 1.21.

[0074] If the average particle size of the raw material after mixing is greater than or equal to the first preset average particle size and less than the second preset average particle size, the control module determines that the preparation of the raw material meets the preset standard and checks whether the preparation of the raw material meets the standard based on the uniformity of the particle size.

[0075] If the average particle size of the raw material after mixing is greater than or equal to the second preset average particle size, the control module determines that the preparation of the raw material does not meet the standard and reduces the preparation time of the preparation part 1.

[0076] Wherein, the first preset average particle size is set to be 0.3 mm, and the second preset average particle size is set to be 0.7 mm.

[0077] Specifically, the reduction amplitude of the modulation duration is positively correlated with the average particle size difference, where the average particle size difference is the difference between the average particle size of the raw material and the second preset average particle size, for example, the reduction amplitude of the modulation duration is set as ΔD, and the average particle size difference is set as Δδ, then ΔD = α × Δδ, α is a reduction amplitude adjustment coefficient, and α is set as 0.72. It can be understood that the greater the average particle size difference, the greater the reduction amplitude of the modulation duration.

[0078] Specifically, the control module increases the modulation rotating speed of the modulation wheel 102 in response to the average particle size obtained after the adjustment of the modulation duration being greater than or equal to the second preset average particle size under the first preset condition, where the first preset condition is that the control module completes the adjustment of the modulation duration, and the increase of the modulation rotating speed of the modulation wheel 102 is calculated by the following formula:

[0079] V1 = V + μ × (β - β2)

[0080] In the formula, V1 represents the increased modulation rotating speed of the modulation wheel 102, V represents the current modulation rotating speed of the modulation wheel 102, β represents the average particle size obtained after the adjustment of the modulation duration, β2 represents the second preset average particle size, and μ represents a modulation rotating speed adjustment coefficient, and μ is set as 1.37.

[0081] Specifically, the control module verifies whether the preparation of the raw material meets the standard based on the uniformity of the particle size, where,

[0082] If the uniformity of the particle size is less than a preset uniformity threshold, the control module verifies that the preparation of the raw material meets the standard and completes the preparation of the raw material according to the current preparation parameter;

[0083] If the uniformity of the particle size is greater than or equal to the preset uniformity threshold, the control module verifies that the preparation of the raw material does not meet the standard and reduces the mixing rotating speed of the mixing wheel 302;

[0084] The uniformity of the particle size is determined according to the variance of the particle size of the raw material after mixing;

[0085] The preset uniformity threshold is set as 0.0065.

[0086] Specifically, the control module determines whether the operation of the forming part 4 meets the standard based on the tabletting density, where,

[0087] If the tabletting density is less than a first preset tabletting density, the control module determines that the operation of the forming part 4 does not meet the standard and lowers the height of the first arc-shaped loading block 4205 in the vertical direction;

[0088] If the tabletting density is greater than or equal to the first preset tabletting density and less than the second preset tabletting density, the control module determines that the operation of the forming part 4 meets the standard and checks whether the operation of the forming part 4 meets the standard based on the tabletting dispersion characteristic;

[0089] If the tabletting density is greater than or equal to the second preset tabletting density, the control module determines that the operation of the forming part 4 does not meet the standard and raises the height of the first arc-shaped loading block 4205 in the vertical direction.

[0090] Specifically, the adjustment of the height of the first arc-shaped loading block is completed by controlling the distance between the mounting seat and the first rotating disc through the hydraulic column;

[0091] In the present application, the first preset tabletting density is set to 1.05 g / cm 3 , and the second preset tabletting density is set to 1.35 g / cm 3 .

[0092] Specifically, the control module checks whether the operation of the forming part 4 meets the standard based on the tabletting dispersion characteristic, wherein,

[0093] If the tabletting dispersion characteristic is the consistent dispersion characteristic, the control module determines that the operation of the forming part 4 does not meet the standard and increases the rotating speed of the forming die 41;

[0094] If the tabletting dispersion characteristic is the late dispersion characteristic, the control module determines that the operation of the forming part 4 meets the standard and continues to prepare the tablet according to the current parameters.

[0095] Specifically, the tabletting dispersion characteristic is determined according to the surface hardness and core hardness of the tablet, wherein, under the condition that the surface hardness of the tablet is greater than the core hardness, the tabletting dispersion characteristic is determined to be the late dispersion characteristic, and under the condition that the surface hardness of the tablet is equal to the core hardness, the tabletting dispersion characteristic is determined to be the consistent dispersion characteristic; in the actual production process, the upper punch 4202 and the lower punch 4301 of the tablet press usually contact and extrude the surface layer of the tablet first, so the case that the surface hardness of the tablet is less than the core hardness is not considered in the present application.
