Description

TECHNICAL FIELD

[0001] The present application relates to the field of penicillin production, and in particular to a penicillin powder injection production equipment and process. BACKGROUND

[0002] The powder injection is a powder product formed by mixing the medicine and reagent and then sterilizing and drying, and is diluted with glucose solution for injection. The injection can be directly injected according to the dosage. The penicillin powder injection refers to the powdered penicillin sodium.

[0003] The filling is a process in the production process of the powder injection, and is a process of filling the powder injection into a Westlin bottle in a certain amount. Since the powder injection is a medical drug, the dosage needs to be cautious. Therefore, the filling also needs to achieve accurate filling.

[0004] Based on the quantitative filling of the powder injection, the applicant searches some prior art: the Chinese utility model patent with the authorization announcement number CN218987110U discloses a bottle powder filling machine with weighing function. The weighing sensor arranged on the filling table weighs the Westlin bottle before and after weighing, so as to achieve the purpose of quantitative filling. However, this method has some disadvantages, for example, since the Westlin bottle needs to be weighed, a certain amount of time is needed for empty bottle weighing. In the filling production line, the filling frequency is very high, and the cumulative empty bottle weighing time is considerable, which delays the filling efficiency. In addition, the weight of the powder injection in each Westlin bottle is very light, only a few grams. Therefore, the sensitivity of the weighing sensor is very high. However, the weight of the empty Westlin bottle is several tens of grams, which is several tens of times of the weight of the powder injection. Therefore, the weighing method before and after filling needs to consider the sensitivity of the sensor and the number of times of using the weighing sensor. Therefore, the cost of the sensor of the filling equipment is very high, and the sensor is easily damaged.

In addition, if the weight detected during the weighing process is incorrect, the motor driving the synchronous belt 102 to run slows down, so that the vial that should be moved to the filling position moves slowly, so that the material receiving body 204 containing the powder injection with incorrect weight is not loaded into the vial. In addition, if the number of times of detecting incorrect weight is frequent, it means that there is a problem with the entire filling equipment, and the weighing element 402 sends a signal to inform the relevant personnel to debug and maintain the equipment.
