Description

Technical Field

[0001] This utility model relates to the field of vaccine production technology, and in particular to a device for precise proportioning and mixing of raw materials for vaccine production. Background Technology

[0002] As a core biological product for the prevention of infectious diseases, vaccines require extremely high precision in raw material proportioning during their production process. Traditional mixing equipment in vaccine production relies on manual control of ingredient mixing, typically involving pre-measuring the components of raw materials and then mixing them. This process is slow in adjusting the proportions of raw materials, affecting production speed and making it prone to errors. Large errors in dispensing can easily lead to the scrapping of an entire batch of products. Utility Model Content

[0003] The purpose of this invention is to provide a device for precise proportioning and mixing of raw materials for vaccine production, so as to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a precise mixing device for raw materials for vaccine production, including a mixing box and a feeding cylinder, wherein a fixed plate is slidably connected inside the feeding cylinder, and the fixed plate is used to precisely control the amount of raw materials added by the feeding cylinder to the mixing box when it slides up and down, and an auxiliary component is fixedly connected to the upper end of the fixed plate;

[0005] The upper end of the fixed plate is rotatably connected to a threaded rod, and the upper end of the fixed plate is fixedly connected to a measuring ruler. The upper ends of the threaded rod and the measuring ruler both extend out of the feeding cylinder. The threaded rod and the feeding cylinder are threadedly connected, and the measuring ruler and the feeding cylinder are slidably connected. When the threaded rod rotates, it is used to change the position and height of the fixed plate inside the feeding cylinder.

[0006] A connecting cylinder is rotatably connected to the middle part of the fixed disk, and a sealing disk is fixedly connected to the outer wall of the connecting cylinder. After the sealing disk rotates, it is used to interrupt the feeding of the feeding cylinder. A limit ball is provided inside the connecting cylinder to control the rotation time of the sealing disk.

[0007] Preferably, the fixed disk has a first through hole in the middle and the sealing disk has a second through hole in the middle. When the first through hole and the second through hole coincide, they are used to feed material downwards onto the sealing disk.

[0008] Preferably, the diameter of the lower opening of the connecting cylinder is smaller than the diameter of the limiting ball, the limiting ball is a plastic ball, and a pressure sensor is fixedly connected inside the fixed disk. After the limiting ball applies pressure to the pressure sensor, it is used to stop the feeding of material to the bottom of the sealing disk.

[0009] Preferably, the fixed disk has a sliding groove in the middle, the sliding groove passes through the fixed disk, and a T-shaped limiting plate is slidably connected in the middle of the sliding groove. The limiting plate is a magnetic plate, and the top of the limiting plate is fixedly connected to the sealing disk. When a force is applied to the limiting plate, it drives the sealing disk to rotate.

[0010] Preferably, a telescopic tube is fixedly connected between the auxiliary component and the inner wall of the upper end of the feeding cylinder. The telescopic tube is formed by interlocking three connecting tubes of different diameters. A feed pipe is fixedly connected to the inner wall of the feeding cylinder. The feed pipe is connected to the connecting tube farthest from the auxiliary component.

[0011] Preferably, the upper end of the auxiliary component is a hemispherical structure, and at least two auxiliary tubes are fixedly connected to the side end of the auxiliary component, with the top end of the auxiliary tubes connected to the fixed plate.

[0013] The beneficial effects of this invention are as follows: a sliding fixed plate is installed inside the feeding cylinder, and the amount of raw materials added to the mixing chamber by the up-and-down movement of the fixed plate is precisely controlled. This allows for precise adjustment of the amount of raw materials added to the mixing chamber each time, avoiding adding too much or too little raw materials, thereby improving the accuracy of the raw material ratio in vaccine production and ensuring the stability and consistency of vaccine quality. Once the position of the fixed plate is adjusted, no further adjustment is required in subsequent production, making it suitable for mass production of vaccines.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] See Figures 1-5 This utility model provides a precise mixing device for raw materials used in vaccine production, comprising a mixing chamber 1 and a feeding cylinder 2. A fixed plate 3 is slidably connected inside the feeding cylinder 2. When the fixed plate 3 slides up and down, it precisely controls the amount of raw materials added from the feeding cylinder 2 to the mixing chamber 1. An auxiliary component 4 is fixedly connected to the upper end of the fixed plate 3; the fixing method can also be welding, riveting, screwing, or gluing. A threaded rod 5 is rotatably connected to the upper end of the fixed plate 3, and a measuring ruler is fixedly connected to the upper end of the fixed plate 3. The upper ends of both the threaded rod 5 and the measuring ruler extend beyond the feeding cylinder. The feed cylinder 2, threaded rod 5, and feeding cylinder 2 are threadedly connected. The measuring ruler and feeding cylinder 2 are slidably connected. When the threaded rod 5 rotates, it changes the position and height of the fixed plate 3 within the feeding cylinder 2. After the raw material addition amount is calculated, the operator only needs to rotate the threaded rod 5 by hand. Due to the limitation of the measuring ruler, the fixed plate 3 will move vertically within the feeding cylinder 2, changing its position and thus altering the raw material storage space below the fixed plate 3. This allows for precise adjustment of the amount of raw material added to the mixing box 1 according to actual production needs, avoiding excessive or insufficient addition of raw materials. The measuring ruler visually displays the position of the fixed plate 3, facilitating accurate control of its height by the operator, thereby precisely controlling the feeding amount.

[0022] A connecting cylinder 10 is rotatably connected to the middle part of the fixed disk 3. A sealing disk 15 is fixedly connected to the outer wall of the connecting cylinder 10. After the sealing disk 15 rotates, it is used to interrupt the feeding of the feeding cylinder 2. A limit ball 11 is provided inside the connecting cylinder 10 to control the rotation time of the sealing disk 15.

[0023] A telescopic tube 8 is fixedly connected between the auxiliary component 4 and the upper inner wall of the feeding cylinder 2. The telescopic tube 8 is composed of three connecting tubes of different diameters that are interlocked. A feed pipe 9 is fixedly connected to the inner wall of the feeding cylinder 2, and the feed pipe 9 is connected to the connecting tube furthest from the auxiliary component 4. When the fixed plate 3 moves up and down to change its position and height, the telescopic tube 8 will extend and retract to avoid interfering with the movement of the fixed plate 3. A feed hose is provided on the outer wall of the feeding cylinder 2. The feed hose is connected to the feed pipe 9, and the other end of the feed hose is connected to the raw material conveying device for conveying raw materials into the auxiliary component 4.

[0024] The upper end of the auxiliary component 4 is a hemispherical structure, and at least two auxiliary pipes 7 are fixedly connected to the side end of the auxiliary component 4. The top end of the auxiliary pipes 7 is connected to the fixed disk 3. A first through hole 13 is connected through the middle of the fixed disk 3, and a second through hole 18 is connected through the middle of the sealing disk 15. When the first through hole 13 and the second through hole 18 coincide, it is used to feed material downwards onto the sealing disk 15. When the raw material reaches the auxiliary component 4, it passes through the auxiliary pipes 7, the first through hole 13, and the second through hole 18 to reach the storage space below. Setting multiple auxiliary pipes 7 can increase the material conveying speed.

[0025] The diameter of the lower opening of the connecting cylinder 10 is smaller than the diameter of the limiting ball 11, which is used to confine the limiting ball 11 within the connecting cylinder 10. Simultaneously, it allows the vaccine raw material to push up the limiting ball 11. The limiting ball 11 is a plastic ball. A pressure sensor 12 is fixedly connected inside the fixed disk 3. After the limiting ball 11 applies pressure to the pressure sensor 12, it stops the feeding of material below the sealing disk 15. After the raw material reaches the inside of the feeding cylinder 2, as the liquid level of the raw material gradually increases, the vaccine raw material liquid level will push up the limiting ball 11, thereby applying pressure to the pressure sensor 12.

[0026] A sliding groove 14 is provided in the middle of the fixed disk 3, which passes through the fixed disk 3. A T-shaped limiting plate 16 is slidably connected in the middle of the sliding groove 14. The limiting plate 16 is a magnetic plate, and its top end is fixedly connected to the sealing disk 15. When a force is applied to the limiting plate 16, it drives the sealing disk 15 to rotate. An electric push rod 17 is fixedly connected to the upper end of the fixed disk 3. The electric push rod is connected to a pressure sensor, and an iron ball is provided at the power output end of the electric push rod 17. When the pressure sensor 12 transmits a signal to the electric push rod 17, the electric push rod pushes the limiting plate 16 to move. The limiting plate 16 drives the sealing disk 15 to rotate, thereby changing the angle of the sealing disk 15 and displacing the first through hole 13 and the second through hole 18. Because the limiting plate 16 can be magnetically attracted to the iron ball at the power output end of the electric push rod 17, when the electric push rod 17 resets, it can drive the limiting plate 16 and the sealing disk 15 to reset, thereby reconnecting the first through hole 13 and the second through hole 18.

[0027] A solenoid valve 6 is installed at the lower outlet of the feeding cylinder 2. The solenoid valve is connected to the electric actuator 17, and a threaded tube is provided at the outlet of the solenoid valve 6. A threaded hole is provided at the upper end of the mixing box 1. The feeding cylinder 2 is threadedly connected to the mixing box 1 through the threaded tube. The solenoid valve 6 is initially closed. When the vaccine raw materials arrive at the feeding cylinder 2, they are stored inside the feeding cylinder 2. When the electric actuator 17 operates and offsets the first through hole 13 and the second through hole 18, the solenoid valve 6 opens, adding the raw materials from the feeding cylinder 2 into the mixing box 1. This prevents the addition of vaccine raw materials while the solenoid valve 6 is open, avoids excessive addition of vaccine raw materials, ensures the accuracy of the raw material ratio in vaccine production, and guarantees the stability and consistency of vaccine quality.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
