Description

Technical Field

[0001] This utility model relates to the field of eye drop production technology, and in particular to a pH adjustment device for eye drop production. Background Technology

[0002] The fast pace of modern life often leads to excessive eye strain, causing eye fatigue, soreness, redness, dryness, and other problems. As a result, more and more people are using anti-fatigue eye drops as an essential medicine. In the actual production of anti-fatigue eye drops, pH adjustment is an important process. pH adjustment refers to the activity of preparing a solution with a certain concentration of hydrogen ions during production or experimentation. By adjusting the pH, the pH value of the eye drops can meet the requirements for production and use.

[0003] The pH adjustment in the production of existing anti-fatigue eye drops is usually done manually. This manual adjustment is not only time-consuming and labor-intensive, increasing the workload of the staff, but also makes it difficult to mix the solution evenly by manpower alone. This can lead to errors due to uneven distribution of components in different parts of the solution, resulting in the pH value not meeting the production and use standards. As a result, the same batch of eye drops needs to be recycled and remade or even directly discarded. Utility Model Content

[0004] The purpose of this invention is to provide a pH adjustment device for eye drop production, which solves the problems mentioned in the background art and facilitates its widespread application.

[0005] A pH adjustment device for producing eye drops includes a base plate, a shell on the base plate, a support frame on the shell, a mixing device one and a mixing device two on the support frame, a conveying device between the mixing device one and the mixing device two and the shell, a stirring device on the inner wall of the shell, a driving device on the outer wall of the shell, a discharge pipe at the bottom of the shell, and a solenoid valve one on the discharge pipe.

[0006] The mixing device includes a mixing tank fixedly mounted on a support frame, a mixing motor mounted on the mixing tank, a mixing shaft fixedly mounted on the output end of the mixing motor, one end of the mixing shaft away from the output end of the mixing motor being rotatably mounted at the bottom of the mixing tank, and a plurality of evenly arranged mixing rods fixedly mounted on the mixing shaft.

[0008] Furthermore, the stirring device includes a stirring shaft one and a stirring shaft two rotatably mounted on the inner wall of the housing. Multiple intersecting stirring plates are fixedly mounted on the stirring shaft one and the stirring shaft two, and multiple evenly arranged stirring through holes are opened on the stirring plates.

[0009] Furthermore, the driving device includes a driven pulley 1 fixedly disposed at the end of the stirring shaft 1 away from the inner wall of the housing, a driven pulley 2 and a driven pulley 3 symmetrically disposed at the end of the stirring shaft 2 away from the inner wall of the housing, a drive belt 1 disposed between the driven pulley 3 and the driven pulley 1, a support plate fixedly disposed on the outer wall of the housing, a drive motor fixedly disposed on the support plate, a drive pulley fixedly disposed on the output end of the drive motor, and a drive belt 2 disposed between the drive pulley and the driven pulley 2.

[0011] Furthermore, the drive motor is an adjustable speed motor.

[0012] As an improvement, the beneficial effects of this utility model are as follows:

[0013] This invention relates to a pH adjustment device for eye drop production. During operation, acid and alkali reagents are first added to mixing devices one and two, respectively. Then, the rotation of the mixing motor drives the mixing shaft, which in turn drives the mixing rod to stir the acid and alkali reagents in the mixing tank, preventing stratification or precipitation. Next, the opening and closing of solenoid valve two delivers the acid and alkali reagents to a measuring cylinder, with the injection volume controlled according to the volume of the eye drop and the graduations on the measuring cylinder. Then, the opening and closing of solenoid valve three injects the acid and alkali reagents into the housing. The rotation of the drive motor then drives drive belts one and two, which in turn drive stirring shafts one and two. The rotation of stirring shafts one and two causes the stirring plate to thoroughly mix the eye drop and the acid and alkali reagents, thereby adjusting the pH value of the eye drop. This precise pH adjustment significantly improves the production quality and efficiency of the eye drops. Attached Figure Description
