Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid level detection technology, specifically to a liquid level detection mechanism for a medicine supply tank. Background Technology
[0002] Liquid substances in supply tanks refer to liquid substances that are stored in supply tanks during the production of pharmaceuticals, bioengineering, or medical preparations, awaiting use or participating in the process. They typically include active pharmaceutical ingredients (APIs), buffer solutions, culture media, solvents, intermediates, semi-finished products, or final formulations. These liquid substances have clearly defined components, concentrations, and physicochemical properties. They are critical materials that need to be precisely controlled, transported, and measured on the production line. The reliability of their storage and management is directly related to the quality, safety, and compliance of the final product.
[0003] The liquid level detection mechanism for the supply tank is an automated device designed specifically for the pharmaceutical and biological product industries to monitor the liquid level in the tank in real time and with high accuracy. It typically uses high-precision sensors, an integrated control system, and a digital display unit to detect liquid level changes non-contactly and continuously, and transmits the data to a central monitoring system to ensure the continuity of the production process, accurate feeding, and safety compliance.
[0004] However, existing liquid level detection mechanisms for supply tanks still have shortcomings. The supply tanks in the existing technology are mostly vertical cylindrical structures equipped with a feed inlet located at the top of the supply tank. When performing liquid level detection, the detection end of the detector needs to be aligned with the feed inlet to ensure that the detection end of the detector can directly shine on the surface of the liquid. However, when the supply tank is placed in the liquid level detection mechanism, the position of the feed inlet on the surface of the supply tank is not uniform, which requires manual rotation of the supply tank, which is quite cumbersome.
[0005] Therefore, we propose a liquid level detection mechanism for supply tanks to address the problems mentioned above. Utility Model Content
[0006] The purpose of this utility model is to provide a liquid level detection mechanism for a supply tank, so as to solve the problem mentioned in the background art that when the supply tank is placed in the liquid level detection mechanism, the position of the feed inlet on the surface of the supply tank is not the same, which requires manual rotation of the supply tank, which is quite cumbersome.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A liquid level detection mechanism for a supply tank includes a frame and an ultrasonic level gauge body. A transmission mechanism for moving the supply tank is located at the bottom of the frame. A baffle for positioning the supply tank is located inside the frame. Several rollers for driving the supply tank to rotate are rotatably connected inside the baffle. A synchronous drive mechanism for driving the rollers to rotate is located on one side of each roller. A positioning frame for positioning the supply tank is rotatably connected inside the frame. A flipping mechanism for driving the positioning frame to rotate is located on one side of the positioning frame. A lifting mechanism for driving the ultrasonic level gauge body to rise and fall is located inside the frame. The lifting end of the lifting mechanism is connected to the ultrasonic level gauge body.
[0008] Preferably, the transmission mechanism includes a transmission roller rotatably connected inside the frame, the surface of the transmission roller being engaged with a transmission belt capable of transmission, and a motor that drives the transmission roller to rotate being fixedly connected to one end of the frame, the output shaft of the motor being fixedly connected to one end of the transmission roller.
[0009] Preferably, the surface of the conveyor belt is rotatably connected with a number of ball bearings that drive the supply tank to move, and the ball bearings are in contact with the bottom of the supply tank.
[0010] Preferably, the frame is rotatably connected to a plurality of support rollers that support the supply tank, and the plurality of support rollers are located inside the conveyor belt.
[0011] Preferably, the synchronous drive mechanism includes a second motor fixedly connected to one side of the baffle, a first gear fixedly connected to the output shaft of the second motor, a second gear meshing with the surface of the first gear, a connecting rod fixedly connected inside the second gear, and a plurality of rollers fixedly connected to the surface of the connecting rod.
[0012] Preferably, the rollers are provided with several anti-slip grooves on their surfaces to increase friction, which facilitates the rotation of the supply tank.
[0013] Preferably, the flipping mechanism includes a guide post fixedly connected to one end of the positioning frame, a cylinder fixedly connected inside the frame, a sliding plate fixedly connected to the cylinder output to drive the guide post to move, a sliding groove adapted to the guide post on the surface of the sliding plate, and the guide post slidably connected in the sliding groove.
[0014] Preferably, the surface of the positioning frame is rotatably connected with a number of guide wheels to facilitate the rotation of the supply tank, and the number of guide wheels are in contact with the surface of the supply tank.
[0015] Preferably, the lifting mechanism includes a motor three fixedly connected to the surface of the frame, a lead screw fixedly connected to the output shaft of the motor three, the lead screw being rotatably connected inside the frame, a lifting plate being threadedly connected to the surface of the lead screw, the lifting plate being slidably connected inside the frame, and one end of the lifting plate being fixedly connected to the ultrasonic level gauge body.
[0016] Preferably, the detection end of the ultrasonic level gauge body corresponds to the opening of the supply tank, and the detection end of the ultrasonic level gauge body and the baffle are on the same plane.
[0017] Compared with the prior art, the beneficial effects achieved by this utility model are: The supply tank is driven to one side of the baffle by the transmission mechanism, so that the supply tank contacts the surface of several rollers. The positioning frame is flipped by the flipping mechanism, so that the positioning frame contacts the surface of the supply tank. The synchronous drive mechanism is activated to make several rollers rotate, thereby driving the supply tank to rotate, so that the feed port on the surface of the supply tank corresponds to the detection end of the ultrasonic level gauge body. Then the liquid level of the medicine in the supply tank is detected, which facilitates automatic positioning of the feed port on the surface of the supply tank, which is convenient and fast.
[0018] The cylinder drives the sliding plate to move, which in turn drives the guide column to move through the sliding groove. The guide column then drives the positioning frame to rotate inside the frame, causing the positioning frame to flip. This allows the positioning frame to drive several guide wheels to contact the surface of the supply tank. When the supply tank rotates, the guide wheels facilitate the rotation of the supply tank, making it easy to position the supply tank and preventing it from shifting during testing.
[0019] The motor drives the lead screw to rotate, which in turn drives the lifting plate to slide inside the frame. This movement of the lifting plate causes the ultrasonic level gauge to rise and fall, reducing the distance between the detection end of the ultrasonic level gauge and the surface of the liquid in the supply tank, thus improving the detection accuracy of the ultrasonic level gauge.

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: like Figures 1-4 As shown, a liquid level detection mechanism for a supply tank includes a frame 2 and an ultrasonic level gauge body 1. The bottom of the frame 2 is provided with a transmission mechanism that drives the supply tank to move. Inside the frame 2, there is a baffle 3 for positioning the supply tank. Inside the baffle 3, there are a plurality of rollers 4 that drive the supply tank to rotate. On one side of the plurality of rollers 4, there is a synchronous drive mechanism that drives the plurality of rollers 4 to rotate. Inside the frame 2, there is a positioning frame 5 for positioning the supply tank. On one side of the positioning frame 5, there is a flipping mechanism that drives the positioning frame 5 to rotate. Inside the frame 2, there is a lifting mechanism that drives the ultrasonic level gauge body 1 to rise and fall. The lifting end of the lifting mechanism is connected to the ultrasonic level gauge body 1.
[0024] like Figures 1-4 As shown, the supply tank is driven to one side of the baffle 3 by the transmission mechanism, so that the supply tank contacts the surface of several rollers 4. The positioning frame 5 is flipped by the flipping mechanism, so that the positioning frame 5 contacts the surface of the supply tank. The synchronous drive mechanism is activated to make several rollers 4 rotate, thereby driving the supply tank to rotate, so that the feed port on the surface of the supply tank corresponds to the detection end of the ultrasonic level gauge body 1. Then, the liquid level of the medicine in the supply tank is detected. The lifting mechanism drives the ultrasonic level gauge body 1 to rise and fall, so that the detection end of the ultrasonic level gauge body 1 is closer to the surface of the medicine in the supply tank, improving the detection accuracy of the ultrasonic level gauge body 1 and facilitating automatic positioning of the feed port on the surface of the supply tank, which is convenient and fast.
[0025] The ultrasonic level gauge body 1 operates on the principle of time difference: the instrument antenna emits high-frequency electromagnetic waves or sound pulses, the signal is reflected after reaching the surface of the liquid, and then received by the instrument; by accurately calculating the time difference between transmission and reception, and combining it with the speed of wave propagation in the air, the distance from the liquid surface to the antenna can be calculated, thereby converting the accurate real-time liquid level height; this method does not come into direct contact with the liquid, avoiding the risk of contamination, and is very suitable for the stringent requirements of hygiene and sterility in the pharmaceutical industry.
[0026] Furthermore, such as Figures 1-3As shown, the transmission mechanism includes a transmission roller 6 rotatably connected inside the frame 2. A transmission belt 7 capable of transmission is engaged on the surface of the transmission roller 6. A motor 9 that drives the transmission roller 6 to rotate is fixedly connected to one end of the frame 2. The output shaft of the motor 9 is fixedly connected to one end of the transmission roller 6. A plurality of balls 8 that drive the supply tank to move are rotatably connected to the surface of the transmission belt 7. The plurality of balls 8 are in contact with the bottom of the supply tank. A plurality of support rollers 10 that support the supply tank are rotatably connected inside the frame 2. The plurality of support rollers 10 are located inside the transmission belt 7.
[0027] The motor 9 drives the transmission roller 6 to rotate, which in turn drives the conveyor belt 7. At the same time, several support rollers 10 support the middle of the conveyor belt 7, placing the supply tank on the surface of the conveyor belt 7. When the conveyor belt 7 is in motion, it drives the supply tank to move synchronously. When the supply tank contacts one side of the baffle 3, it is blocked. At the same time, the supply tank rotates on the surface of several balls 8, and then several rollers 4 rotate, thereby driving the supply tank to rotate, so that the feed port on the surface of the supply tank corresponds to the detection end of the ultrasonic level gauge body 1.
[0028] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the synchronous drive mechanism includes a second motor 11 fixedly connected to one side of the baffle 3. The output shaft of the second motor 11 is fixedly connected to a first gear 12. A second gear 13 meshes with the surface of the first gear 12. A connecting rod 14 is fixedly connected inside the second gear 13. The surface of the connecting rod 14 is fixedly connected to several rollers 4. Several anti-slip grooves 15 are provided on the surface of each roller 4 to increase friction, so as to facilitate the rotation of the supply tank.
[0029] The rotation of motor 11 causes gear 12 to rotate, which in turn causes gear 13 to rotate, which in turn causes connecting rod 14 to rotate, which in turn causes roller 4 to rotate, which in turn causes the supply tank to rotate via several anti-slip grooves 15.
[0030] Furthermore, such as Figures 1-3 As shown, the flipping mechanism includes a guide post 16 fixedly connected to one end of the positioning frame 5, a cylinder 17 fixedly connected inside the frame 2, and a sliding plate 18 fixedly connected to the output of the cylinder 17 to drive the guide post 16 to move. The surface of the sliding plate 18 is provided with a sliding groove 19 adapted to the guide post 16. The guide post 16 is slidably connected in the sliding groove 19. Several guide wheels 20 are rotatably connected to the surface of the positioning frame 5 to facilitate the rotation of the supply tank. The several guide wheels 20 are in contact with the surface of the supply tank.
[0031] The cylinder 17 drives the sliding plate 18 to move, which in turn drives the guide column 16 to move through the sliding groove 19. The guide column 16 drives the positioning frame 5 to rotate inside the frame 2, causing the positioning frame 5 to flip in the frame 2. The positioning frame 5 drives several guide wheels 20 to contact the surface of the supply tank. When the supply tank rotates, it is convenient for the several guide wheels 20 to drive the supply tank to rotate.
[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the lifting mechanism includes a motor 22 fixedly connected to the surface of the frame 2. The output shaft of the motor 22 is fixedly connected to a lead screw 21, which is rotatably connected inside the frame 2. A lifting plate 23 is threadedly connected to the surface of the lead screw 21, and the lifting plate 23 is slidably connected inside the frame 2. One end of the lifting plate 23 is fixedly connected to the ultrasonic level gauge body 1. The detection end of the ultrasonic level gauge body 1 corresponds to the opening of the supply tank, and the detection end of the ultrasonic level gauge body 1 and the baffle 3 are on the same plane.
[0033] The motor 22 drives the lead screw 21 to rotate, which in turn drives the lifting plate 23 to slide. The lifting plate 23 slides inside the frame 2, causing the ultrasonic level gauge body 1 to rise and fall. This reduces the distance between the detection end of the ultrasonic level gauge body 1 and the surface of the liquid in the supply tank, thereby improving the detection accuracy of the ultrasonic level gauge body 1.
[0034] The working principle of the liquid level detection mechanism for the supply tank is as follows: Motor 9 drives transmission roller 6 to rotate, which in turn drives conveyor belt 7. Simultaneously, several support rollers 10 support the middle of conveyor belt 7, placing the supply tank on its surface. As conveyor belt 7 moves, the supply tank moves synchronously. When the supply tank contacts baffle 3, it is blocked, and the supply tank rotates on the surface of several balls 8. Then, several rollers 4 rotate, causing the supply tank to rotate, aligning the feed inlet on the surface of the supply tank with the detection end of the ultrasonic level gauge body 1. Motor 11 rotates, driving gear 12 to rotate, which in turn drives gear 13 to rotate, which in turn drives connecting rod 14 to rotate. Connecting rod 14 then drives roller 4 to rotate, causing roller 4 to rotate via several anti-slip grooves 15, allowing the supply tank to rotate on the surface of several balls 8. This facilitates automatic positioning of the feed inlet on the surface of the supply tank, making the process convenient and quick.
[0035] The cylinder 17 drives the sliding plate 18 to move, which in turn drives the guide column 16 to move through the sliding groove 19. The guide column 16 drives the positioning frame 5 to rotate inside the frame 2, causing the positioning frame 5 to flip in the frame 2. This causes the positioning frame 5 to drive several guide wheels 20 to contact the surface of the supply tank. When the supply tank rotates, the guide wheels 20 facilitate the rotation of the supply tank, making it easy to position the supply tank and preventing it from shifting during testing.
[0036] The motor 22 drives the lead screw 21 to rotate, which in turn drives the lifting plate 23 to slide. The lifting plate 23 slides inside the frame 2, causing the ultrasonic level gauge body 1 to rise and fall. This reduces the distance between the detection end of the ultrasonic level gauge body 1 and the surface of the liquid in the supply tank, thereby improving the detection accuracy of the ultrasonic level gauge body 1.
[0037] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
