DETAILED DESCRIPTION

[0020] In order to make the above-mentioned purpose, technical scheme and beneficial effects more clear and definite, the utility model is specifically described below in combination with the drawings.

[0021] For example Figures 1-4As shown, the coating agent mixing tank 1 includes a mixing tank 1, a discharge pipe 8, a metering tank 4, a hopper 6, a liquid discharge pipe 12, a liquid storage tank 9, a liquid level meter 11, a weighing system 7, a stirring roller 13, a liquid leakage plate 22, a sampling pipe 14, and a liquid outlet pipe 15.

[0022] The top surface of the mixing tank 1 is connected to the hopper 6 and is provided with a metering tank 4. A weighing system 7 is installed outside the metering tank 4. The weighing system 7 cooperates with the metering tank 4 to realize quantitative discharge. The weighing system 7 includes a weighing module, a connecting line 19, a junction box 20, and a control box 21. The weighing module is installed outside the mixing tank 1. The weighing module is connected to the connecting line 19. A feeding valve 16 is connected to the feeding pipe 5. A discharge valve 17 is connected to the discharge pipe 8. The feeding valve 16, the junction box 20, and the control box 21 are connected by the connecting line 19. A liquid level meter 11 is arranged inside the liquid storage tank 9 to realize quantitative liquid feeding. The operator can calculate the concentration of the coating agent in advance according to the production requirements. According to the predetermined coating agent concentration, the amount of coating powder and solvent required is determined to realize quantitative mixing. Two stirring rollers 13 and two liquid leakage plates 22 are arranged in parallel in the mixing tank 1. Liquid leakage holes 23 are arranged through the liquid leakage plates 22. The diameter of the liquid leakage holes 23 is 0.5-1 mm. The stirring rollers 13 are selected to be timing stirring rollers 13. The coating powder and the solvent are fully mixed in the mixing tank 1. The liquid leakage holes 23 are arranged through the liquid leakage plates 22 in the mixing tank 1. The liquid leakage plates 22 in the mixing tank 1 are located below the stirring rollers 13. The solute and the solvent of the coating agent are fully mixed in the mixing tank 1. The coating agent after being stirred by the first stirring roller 13 leaks from the first liquid leakage plate 22 and is then stirred and mixed by the second stirring roller 13. After stirring and mixing, the coating agent leaks from the second liquid leakage plate 22 to complete the stirring and mixing operation. The arrangement of the two liquid leakage plates 22 can effectively slow down the leakage speed of the liquid and prolong the stirring time. After mixing, the mixing effect of the coating agent is judged by sampling from the sampling pipe 14. When the mixing effect of the coating agent meets the requirements, the coating agent enters the drug coating operation from the liquid outlet pipe 15.

[0023] When the coating agent mixing tank 1 is used for the preparation and mixing of the coating agent, the coating powder is stored in the hopper 6, and the coating powder solvent is stored in the liquid storage tank 9. During operation, the timing stirring roller 13 is started. The weighed material in the metering tank 4 and the coating powder solvent in the liquid storage tank 9 are simultaneously fed into the mixing tank 1. The coating powder and the coating solvent in the mixing tank 1 are stirred and mixed. The timer outside the timing stirring roller 13 is used for timing. The stirring time is at least 30 min. After the mixing time is reached, the sample is taken from the sampling pipe 14 to observe the mixing effect of the coating agent. Whether there are agglomerates in the coating agent is mainly observed. When there are no agglomerates in the coating agent, the texture is uniform, and the flowability is good. It is determined that the coating agent is uniformly mixed. When agglomerates appear in the coating machine, the stirring roller 13 is started to continue stirring until it is qualified. The qualified coating agent enters the drug coating program from the liquid outlet pipe 15 for the drug coating operation.

[0024] Finally, it is pointed out that the above preferred embodiments are only to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application.
