Description

Technical Field

[0001] This invention relates to the field of drug mixing technology, and more particularly to a mixer that ensures uniform drug distribution. Background Technology

[0002] In the production of pharmaceuticals, it is sometimes necessary to mix multiple raw materials together. Currently, commonly used mixing devices generally pour the raw materials into a mixing drum at once and stir them repeatedly by rotating a stirring shaft to achieve mixing. However, for some drugs that require delayed mixing reactions, it is not convenient to control the flow rate of the drug to achieve the operation of stirring while adding the drug, which affects the mixing efficiency and mixing effect. Therefore, those skilled in the art provide a mixer that ensures uniform distribution of the drug to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mixer that ensures uniform drug distribution.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mixer for ensuring uniform drug distribution includes a mixing cylinder. A cover plate is fixedly connected to the top of the mixing cylinder, and drug delivery cylinders are fixedly connected to both sides of the cover plate. The bottom of each drug delivery cylinder is fixedly connected to a guide pipe, which passes through the cover plate and extends into the interior of the mixing cylinder. A mixing assembly is provided inside the mixing cylinder, and plugs are provided inside the two guide pipes. A drive assembly for controlling the intermittent opening of the plugs is provided on the top of the cover plate. When the mixing assembly is working, the drive assembly opens the plugs to allow the drug liquid to flow intermittently into the mixing cylinder.

[0006] As a further embodiment of this utility model, the mixing assembly comprises multiple stirring rods, and a drive shaft is movably connected through the middle of the cover plate. The multiple stirring rods are respectively fixedly connected to the outer circumference of the drive shaft, and the cover plate is provided with a transmission assembly that causes the drive shaft to rotate.

[0007] As a further embodiment of this utility model, the transmission assembly includes a first pulley and a second pulley. The second pulley is fixedly connected to the top end of the transmission shaft. A motor is fixedly connected to the cover plate. The first pulley is fixedly connected to the output shaft of the motor, and the first pulley and the second pulley are connected by a belt.

[0008] As a further embodiment of this utility model, the drive assembly includes a gear, a rack, and a slide. A rotating shaft is movably connected through both of the two guide tubes. The plug is fixedly connected to the outer circumference of the rotating shaft and fits against the inner wall of the guide tube. Gears are fixedly connected to both ends of the rotating shaft. Two sliding openings are opened on the surface of the cover plate. The slides are movably connected inside the sliding openings respectively. One end of the rack is fixed to the slide.

[0009] As a further embodiment of this utility model, a cam is fixedly connected to the outer circumference of the top of the transmission shaft, a top head is fixedly connected to one side of each of the two slides and the top head contacts the cam, and a spring is fixedly connected to one side of each of the two slides and one end of the spring is fixed to the cover plate.

[0010] As a further embodiment of this utility model, the inner walls of both sides of the mixing cylinder are fixedly connected with conical seats, and the conical seats are respectively located directly below the guide pipe.

[0011] As a further improvement of this invention, the bottom of the mixing cylinder is fixedly connected to two discharge pipes.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By using the cam and the top head in combination, the plug can be opened intermittently, and the drug can flow into the mixing cylinder intermittently, thereby controlling the drug flow rate. At the same time, the stirring rod stirs the drug during the drug feeding process, realizing the operation of drug feeding and mixing at the same time, which helps to improve the mixing efficiency and effect.

[0014] 2. By designing a conical seat, the liquid medicine falls onto the conical seat during the outflow process, and then flows into the mixing cylinder from multiple side walls of the conical seat. This allows the liquid medicine to fall more dispersedly and evenly, which is beneficial for the mixing of the liquid medicine. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0020] Reference Figures 1-3 A mixer for ensuring uniform drug distribution includes a mixing cylinder 1. A cover plate 8 is bolted to the top of the mixing cylinder 1. Two drug delivery cylinders 6 are bolted to both sides of the cover plate 8. The two drug delivery cylinders 6 contain the drug solution to be mixed. The bottom of each drug delivery cylinder 6 is fixedly connected to a guide pipe 7, which passes through the cover plate 8 and extends into the interior of the mixing cylinder 1. The drug solution can flow into the interior of the mixing cylinder 1 through the guide pipe 7. A mixing assembly is provided inside the mixing cylinder 1. A plug 18 is provided inside each of the two guide pipes 7. A drive assembly is provided on the top of the cover plate 8 to control the intermittent opening of the plug 18. When the mixing assembly is working, the drive assembly opens the plug 18 so that the drug solution flows intermittently into the mixing cylinder 1.

[0021] In this invention, the mixing assembly consists of multiple stirring rods 11. A drive shaft 5 is rotatably connected through the middle of the cover plate 8. The multiple stirring rods 11 are respectively fixed to the outer circumference of the drive shaft 5 by bolts. The cover plate 8 is provided with a transmission assembly that rotates the drive shaft 5. The drive shaft 5 is rotated through the transmission assembly. During the process of the liquid medicine falling in, the drive shaft 5 drives the multiple stirring rods 11 to rotate, so that the liquid medicine is stirred and mixed.

[0022] In this invention, the transmission assembly includes a first pulley 3 and a second pulley 4. The second pulley 4 is keyed to the top of the transmission shaft 5. A motor 2 is bolted to the cover plate 8. The first pulley 3 is keyed to the output shaft of the motor 2, and the first pulley 3 and the second pulley 4 are connected by a belt. The drive assembly includes a gear 17, a rack 19, and a slide 15. A rotating shaft 16 is rotatably connected through each of the two guide pipes 7. A plug 18 is bolted to the outer circumference of the rotating shaft 16, and the plug 18 fits against the inner wall of the guide pipe 7. Gears 17 are keyed to both ends of the rotating shaft 16. Two sliding openings are provided on the surface of the cover plate 8, and slides 15 are slidably connected inside the sliding openings. One end of the rack 19 is fixed to the slide 15. A cam 13 is keyed to the outer circumference of the top of the transmission shaft 5. A top head 9 is bolted to one side of each of the two slides 15, and the top head 9 contacts the cam 13. One side of each of the two slides 15 is welded with... A spring 14 is provided, with one end of the spring 14 fixed to the cover plate 8. The rotation of the motor 2 causes the first pulley 3 to rotate, which in turn drives the second pulley 4 to rotate via a belt. The rotation of the second pulley 4 causes the transmission shaft 5 to drive the cam 13 to rotate. The rotation of the cam 13 cyclically squeezes the top head 9. The top head 9 is squeezed, causing the slide 15 to move to one side along the slide opening. The spring 14 is stretched by the force, and the movement of the slide 15 causes the rack 19 to move. The movement of the rack 19 causes the gear 17 to rotate, and the rotation of the gear 17 causes the rotating shaft 16 to drive the plug 18 to rotate. At this time, as the plug 18 rotates from the horizontal to the vertical direction, the liquid medicine falls from the lower medicine cylinder 6 through the guide pipe 7 into the interior of the mixing cylinder 1. When the cam 13 rotates to the point of disengagement from the top head 9, the spring 14 rebounds and resets, causing the slide 15 to drive the rack 19 to reset. The gear 17 drives the rotating shaft 16 to reverse, and the plug 18 rotates and resets again to block the guide pipe 7, thus stopping the flow of the liquid medicine and controlling the flow rate of the medicine.

[0023] In this invention, the inner walls of the mixing cylinder 1 on both sides are fixed with conical seats 12 by bolts, and the conical seats 12 are located directly below the guide pipe 7. The liquid medicine falls from the guide pipe 7 onto the conical seats 12 and flows into the mixing cylinder 1 from multiple side walls of the conical seats 12, which can make the liquid medicine fall more dispersed.

[0024] In this invention, the bottom of the mixing cylinder 1 is fixedly connected to two discharge pipes 10. When the valve of the discharge pipe 10 is opened, the mixed liquid can be discharged through the discharge pipe 10.

[0025] Working principle: When needed, the liquid medicine is poured into the two medicine cylinders 6, and the motor 2 is started. The rotation of the motor 2 causes the first pulley 3 to rotate, which in turn drives the second pulley 4 to rotate via a belt. The rotation of the second pulley 4 causes the transmission shaft 5 to drive the cam 13 to rotate. The rotation of the cam 13 cyclically compresses the top head 9. The compression of the top head 9 causes the slide 15 to move to one side along the sliding opening. The spring 14 is stretched by the force, and the movement of the slide 15 causes the rack 19 to move. The movement of the rack 19 causes the gear 17 to rotate, and the rotation of the gear 17 causes the rotating shaft 16 to drive the plug 18 to rotate. At this time, the plug 18 moves from the horizontal... During the rotation to the vertical position, the liquid medicine falls from the lower medicine cylinder 6 through the guide pipe 7 into the interior of the mixing cylinder 1. During the process of the liquid medicine falling in, the drive shaft 5 drives multiple stirring rods 11 to rotate, so that the liquid medicine is stirred and mixed. When the cam 13 rotates to disengage from the top head 9, the spring 14 rebounds and resets, causing the slide 15 to drive the rack 19 to reset. The gear 17 drives the rotating shaft 16 to reverse, and the plug 18 rotates and resets to block the guide pipe 7, so that the liquid medicine stops flowing out. Through the cyclic rotation of the cam 13, the liquid medicine can fall intermittently into the mixing cylinder 1, realizing the operation of adding medicine and mixing at the same time.

[0026] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described in detail here.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
