[0016] Furthermore, the tablet collecting module comprises a tablet scraper arranged on the upper end surface of the forming mold, and a blanking chute arranged at the end of the tablet scraper; and a collecting frame is arranged at the output end of the blanking chute.

[0017] Furthermore, the control module determines whether the preparation of the raw materials meets the standards according to the average particle size of the raw materials after the mixing, wherein:

[0018] 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 rate of each steam delivery pipe of the modulation part;

[0019] 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 verifies whether the preparation of the raw material meets the standard based on the uniformity of the particle size;

[0020] 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 standards and reduces the modulation time of the modulation unit.

[0023] Furthermore, the control module verifies whether the preparation of the raw material meets the standards based on the uniformity of the particle size, wherein:

[0024] 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 parameters;

[0025] If the uniformity of the particle size is greater than or equal to a preset uniformity threshold, the control module verifies that the preparation of the raw material does not meet the standard and reduces the mixing speed of the mixing wheel;

[0027] Furthermore, the control module determines whether the operation of the forming unit meets the standard based on the tableting density, wherein:

[0028] If the tableting density is less than the first preset tableting density, the control module determines that the operation of the forming unit is not up to standard and lowers the height of the first arc-shaped loading block in the vertical direction;

[0029] If the tableting density is greater than or equal to the first preset tableting density and less than the second preset tableting density, the control module determines that the operation of the forming unit meets the standard and verifies whether the operation of the forming unit meets the standard based on the tableting dispersion characteristics;

[0033] If the tableting dispersion characteristic is a post-dispersion characteristic, the control module determines that the operation of the forming unit meets the standard and continues to prepare tablets according to the current parameters.

[0034] Furthermore, the tablet dispersion characteristics are determined based on the surface hardness and core hardness of the tablet, wherein the tablet dispersion characteristics are determined to be post-dispersion characteristics under the condition that the surface hardness of the tablet is greater than the core hardness, and the tablet dispersion characteristics are determined to be consistent dispersion characteristics under the condition that the surface hardness of the tablet is equal to the core hardness.

[0035] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention is provided with a modulation section, a cooling section, a mixing section and a molding section, and is also equipped with a first detection module and a second detection module during the raw material preparation process, which can respectively obtain key parameters such as the particle size and uniformity of the raw materials and the density and hardness of the tablets, and the present invention is provided with a control module, which determines the compliance of the tablet preparation process according to the data obtained by the detection module, thereby adjusting the preparation parameters such as steam flow, modulation time, mixing wheel speed, and molding mold speed in real time, thereby realizing intelligent monitoring and precise control of the tablet preparation process.

[0036] Furthermore, the present invention is also provided with a tablet collecting module, and the tablet scraper promptly scrapes the finished tablets into the blanking trough for collection, thereby improving production efficiency.

[0037] Furthermore, the present invention realizes automation of the tablet preparation process by arranging upper and lower return springs on the upper and lower punches so that the upper punch can independently complete the pressing and rising of the punch, and the lower punch can eject and fall back the finished tablet.

[0038] Furthermore, the present invention determines whether the preparation of the raw materials meets the standards based on the average particle size of the raw materials after the mixing is completed through the control module. If it meets the preset standards, the tablets are prepared according to the current parameters. If it does not meet the standards, the steam flow rate of each steam delivery pipe of the modulation part is adjusted or the uniformity of the particle size is verified, thereby improving the accuracy of the parameters for the preparation of the raw materials.

[0039] Furthermore, when the average particle size obtained after the modulation time is adjusted is secondarily determined and is determined to be unsatisfactory, the modulation speed of the modulation wheel is increased, thereby promoting sufficient mixing of the raw materials.

[0040] Furthermore, the present invention further determines whether the uniformity of the particle size meets the standard through the control module, and reduces the mixing speed of the mixing wheel when the standard is not met, thereby achieving consistency of the particle size.

[0041] Furthermore, the present invention determines whether the operation of the forming part meets the standard according to the tableting density through the control module, and when it is determined that it does not meet the standard, adjusts the height of the first arc-shaped loading block, thereby achieving flexible control of the preparation process.

[0042] Furthermore, the control module of the present invention verifies whether the operation of the molding part meets the standards based on the tablet dispersion characteristics. If the standards are not met, the rotation speed of the molding die is optimized, thereby improving the quality assurance of the finished tablets. Controlling the tablet dispersion characteristics can reduce the melting of the tablets during the initial entry into the water, and allow the tablets to melt quickly after sinking to the bottom of the water.

[0070] Specifically, the control module determines whether the preparation of the raw materials meets the standards according to the average particle size of the raw materials after the mixing, wherein:

[0071] If the average particle size of the raw material after the mixing is completed 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 rate of each steam delivery pipe 104 of the modulation part 1. The steam flow rate of each steam delivery pipe 104 of the modulation part 1 is increased by the following formula:

[0072]

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

For example, the reduction amplitude of the modulation time is set to △D, and the average particle size difference is set to △δ, then △D=α×△δ, α is the reduction amplitude adjustment coefficient, and α is set to 0.72. It can be understood that the larger the average particle size difference, the greater the reduction amplitude of the modulation time.

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

[0084] The uniformity of particle size is determined based on the variance of the particle sizes of the raw materials used to complete the blend;

[0085] Set the preset uniformity threshold to 0.0065.

[0086] Specifically, the control module determines whether the operation of the forming unit 4 meets the standard based on the tableting density, wherein:

[0087] If the tableting density is less than the first preset tableting density, the control module determines that the operation of the forming unit 4 is not up to standard and lowers the height of the first arc-shaped loading block 4205 in the vertical direction;

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

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

[0090] Specifically, the height of the first arc-shaped loading block is adjusted by controlling the distance from the mounting seat to the first rotating disk through a hydraulic column;

[0091] The first preset tablet density is set to 1.05 g / cm 3 , set the second preset tablet density to 1.35g / cm 3 .

[0092] Specifically, the control module verifies whether the operation of the forming unit 4 meets the standard based on the tableting dispersion characteristics, wherein:

[0093] If the tableting dispersion characteristic is a uniform dispersion characteristic, the control module determines that the operation of the forming unit 4 is not up to standard and increases the rotation speed of the forming die 41;

[0094] If the tableting dispersion characteristic is a post-dispersion characteristic, the control module determines that the operation of the forming unit 4 is up to standard and continues to prepare tablets according to the current parameters.

[0095] Specifically, the tablet dispersion characteristics are determined based on the surface hardness and core hardness of the tablet, wherein the tablet dispersion characteristics are determined to be post-dispersion characteristics when the surface hardness of the tablet is greater than the core hardness, and the tablet dispersion characteristics are determined to be consistent dispersion characteristics when the surface hardness of the tablet is equal to the core hardness. In the actual production process, the upper punch 4202 and the lower punch 4301 of the tablet press usually first contact the surface of the extruded tablet, so the situation where the surface hardness of the tablet is less than the core hardness is not considered in the present invention.
