Description

Technical Field

[0001] The utility model belongs to the technical field of biopharmaceuticals, and in particular relates to a liquid quantitative filling device for a biopharmaceutical liquid preparation tank. Background Art

[0002] The biopharmaceutical preparation tank is a tank that mixes various liquid medicines together for reaction. During the liquid medicine production reaction process, a certain amount of raw materials needs to be added to the tank.

[0003] In the Chinese patent with publication number CN212999826U, a quantitative feeding device for injection production is mentioned. The specification discloses that in the production and preparation process of injection, various raw materials need to be mixed in a certain proportion, but the current mixing devices are all manually fed, which is time-consuming and labor-intensive. On the other hand, manual addition cannot guarantee a certain amount of feeding each time, and it is necessary to weigh before feeding, which affects production efficiency. Weighing errors will also lead to poor product quality.

[0004] However, in the above scheme, after the raw materials are added, the raw materials are also crushed by the crushing mechanism, which easily causes part of the raw materials to remain on the crushing mechanism, which makes the raw materials not quantitatively added each time and there is a certain difference. Utility Model Content

[0005] The utility model aims to provide a quantitative liquid filling device for a biopharmaceutical liquid preparation tank, so as to solve the problem that the current mixing devices in the prior art are all manually added and it is difficult to maintain the quantitative amount each time.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A quantitative liquid filling device for a biopharmaceutical liquid preparation tank comprises a tank body, an end face of the tank body is provided with a filling mechanism, the filling mechanism comprises three fixing rods fixedly connected to the end face of the tank body, one end of the three fixing rods close to each other is fixedly connected to a cylinder, a circular hole is opened at the bottom of the cylinder, a cylinder is fixedly connected to the bottom of the cylinder, a motor is fixedly connected to the bottom end of the cylinder, a first gear is fixedly connected to the output end of the motor, the end face of the tank body is rotatably connected to a round rod, the arc surface of the round rod is fixedly connected to a second gear, the second gear is meshed with the first gear, and the end of the round rod close to the cylinder is fixedly connected to a baffle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model is provided with a first gear, a second gear and a baffle.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 5 As shown, the utility model provides a quantitative liquid filling device for a biopharmaceutical liquid preparation tank, comprising a tank body 1, a filling mechanism 2 is provided on the end face of the tank body 1, the filling mechanism 2 comprises three fixed rods 21 fixedly connected to the end face of the tank body 1, a cylinder 22 is fixedly connected to one end of the three fixed rods 21 close to each other, a circular hole 23 is opened at the bottom of the cylinder 22, a cylinder 24 is fixedly connected to the bottom of the cylinder 22, a motor 25 is fixedly connected to the bottom end of the cylinder 24, a first gear 26 is fixedly connected to the output end of the motor 25, a round rod 28 is rotatably connected to the end face of the tank body 1, a second gear 27 is fixedly connected to the arc surface of the round rod 28, the second gear 27 is meshed with the first gear 26, and a baffle 29 is fixedly connected to one end of the round rod 28 close to the cylinder 22.

[0025] After the motor 25 drives the second gear 27 to rotate for one circle, the baffle 29 can return to its original position, thereby re-blocking the circular hole 23 and ensuring that the amount of filling is determined each time.

[0026] Two support rods 210 are fixedly connected to the bottom of the cylinder 22 . One end of the two support rods 210 close to each other is fixedly connected to a limiting tube 211 . One end of the limiting tube 211 is connected to a circular tube 212 . The bottom end of the circular tube 212 is connected to the tank body 1 .

[0027] The baffle 29 fits the bottom surface of the cylinder 22, and the position of the baffle 29 corresponds to the position of the circular hole 23. The limiting tube 211 is inclined toward the direction close to the tank body 1, and the cross-section of the support rod 210 is L-shaped.

[0028] In this embodiment, the limiting tube 211 is inclined toward the direction close to the tank body 1 to facilitate the sliding of the raw materials.

[0029] The end surface of the tank body 1 is provided with an auxiliary mechanism 3, which includes a support rod 31 fixedly connected to the end surface of the tank body 1, one end of the support rod 31 is fixedly connected to a sleeve 32, the inner wall of the sleeve 32 is slidably connected to two slide posts 33, one end of the two slide posts 33 close to each other is fixedly connected to a spring 34, and the bottom surface of the first gear 26 is fixedly connected to a strip plate 35. The cross-sectional shape of the strip plate 35 is L-shaped.

[0030] The ends of the two sliding posts 33 that are away from each other are both hemispherical, and the spring 34 is located inside the sleeve 32 .

[0031] The slide column 33 can hit the limiting tube 211 to make it vibrate, which facilitates the rapid sliding of the raw material.

[0032] The working principle of the utility model is as follows: when using, the staff will store the raw materials in the cylinder 22 in advance when filling the raw materials. When the raw materials need to be filled, the motor 25 is started, the motor 25 drives the first gear 26 to rotate, the first gear 26 drives the second gear 27 to rotate, and the baffle 29 rotates accordingly. The circular hole 23 will appear with the rotation of the baffle 29, and the raw materials inside the cylinder 22 will fall into the limiting tube 211, and then slide into the circular tube 212 and fall into the tank body 1. As long as the motor 25 is set to drive the first gear 26 to rotate, the first gear 26 drives the second gear 27 to rotate, and the baffle 29 rotates accordingly. After the second gear 27 rotates one circle, the baffle 29 can return to its original position to cover the circular hole 23, so that the amount of filling each time is constant. When the first gear 26 rotates, the strip plate 35 will rotate accordingly, and the strip plate 35 will squeeze the sliding column 33 below. The squeezed end of the sliding column 33 is hemispherical and slides upward under the squeeze. Under the connection of the spring 34, the two sliding columns 33 slide upward together and hit the limiting tube 211, which vibrates the limiting tube 211 and facilitates the material on the limiting tube 211 to slide quickly.
