Description

Technical Field

[0001] This utility model relates to the field of mixing and granulation stirring technology, and in particular to a mixing and granulation stirring assembly. Background Technology

[0002] The square cone hopper mixer is mainly used for solid materials in pharmaceutical production processes. Pharmaceutical production lines composed of it have the advantages of large loading capacity, high mixing uniformity, and no cross-contamination or dust pollution. It is quite common in drug processing and production.

[0003] Existing technologies, such as the utility model patent with publication number CN209287228U, disclose a biomass pellet mill. This patent includes a pellet mill body, which comprises a mixing tank and a pelletizing tank. A stirring motor is bolted to the upper end of the mixing tank. A rotating rod is installed inside the mixing tank, with its upper end penetrating the mixing tank and engaging with the output shaft of the stirring motor. A scraper frame is welded to the surface of the rotating rod, and a scraper is movably engaged inside the scraper frame. The mixing tank utilizes the stirring rod and scraper frame. When the stirring motor rotates, the rotating rod drives the stirring rod and scraper frame to rotate inside the mixing tank, causing the material inside the tank to be stirred by the stirring rod. Simultaneously, the scraper frame removes debris from the inner wall of the mixing tank by driving the scraper. This increases the mixing and batching of materials before pelleting, reduces mixing before the material enters the pellet mill body, reduces the number of pelleting steps, and increases the cleanliness of the inner wall of the mixing tank.

[0004] In the process of drug processing and production, it has been found that when drugs are mixed, a mixer is used for stirring. The mixing device of a typical mixer is equipped with an excipient feeding port. However, when excipients need to be added, it is inconvenient to connect the feeding tank and the feeding port, which can lead to the problem of the connection limit position being misaligned. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that when drugs are mixed and processed, a mixer is used for stirring. The mixing device of a typical mixer is equipped with an excipient feeding port. However, when excipients need to be added, it is inconvenient to connect the feeding tank and the feeding port, which can lead to the displacement of the connection limit position.

[0006] To solve the above technical problems, this utility model provides a mixing and granulation stirring assembly, including: a first mounting frame and a second mounting frame. A mixing tank is rotatably connected to one side of the first and second mounting frames that are close to each other. A feed pipe is fixedly passed through one side of the upper surface of the mixing tank. A discharge port is provided at the bottom end of the mixing tank. A lifting frame is installed on the side wall of the first mounting frame. A feeding tank is installed on the surface of the lifting frame. The feed pipe is located directly below the feeding tank. An adjustment device is provided on the arc surface of the feed pipe. The adjustment device includes a fixed frame, and the inner wall of the fixed frame is connected to the feed pipe. The inner wall of the fixed frame is rotatably connected to three limiting plates. The inner wall of the feed pipe is fixedly connected to a limiting frame corresponding to the limiting plate. The inner wall of the limiting frame is slidably connected to a rotating frame. The end of the rotating frame away from the limiting frame is rotatably connected to the surface of the limiting plate. Slider blocks are fixedly connected to both sides of the rotating frame. Sliding grooves are opened on both sides of the inner wall of the limiting frame. The inner wall of the sliding groove is slidably connected to the surface of the slider. A tension spring is fixedly connected to the end of the rotating frame away from the limiting plate. The upper end of the tension spring is fixedly connected to the upper end of the inner wall of the limiting frame.

[0007] The effect achieved by the above components is as follows: when operating the entire mixing tank, it is necessary to add auxiliary materials for mixing. At this time, in order to facilitate the connection between the feeding tank and the feed pipe, the rotating limit plate in the adjustment device can be used for guidance, which helps to quickly fix and protect the tank.

[0008] Preferably, both ends of the inner arc surface of the fixing frame are fitted with coil springs, and the two ends of the coil springs are fixedly connected to the limiting plate and the fixing frame, respectively.

[0009] The effect achieved by the above components is that the torsional force generated by the coil spring can press and fix the position of the limiting plate, preventing the limiting plate from shaking.

[0010] Preferably, a friction pad, which is a rubber pad, is fixedly connected to the upper surface of the limiting plate.

[0011] The effect achieved by the above components is that when the limiting plate guides and connects the entire feeding tank, the rubber friction pad can be used for contact and limiting.

[0012] Preferably, the upper cross-section of the limiting plate is arc-shaped, and the length of the limiting plate is adapted to the bottom cross-sectional dimensions of the feeding tank.

[0013] The effect achieved by the above components is that the limiting plate with an arc-shaped upper section can be conveniently and quickly guided and limited.

[0014] Preferably, the arc surface of the discharge port is provided with an auxiliary device, the auxiliary device including a connecting ring, the inner wall of the connecting ring being fixedly connected to the arc surface of the discharge port, and connecting frames being fixedly connected to the two end side walls of the connecting ring. The connecting frames have a "U" shaped cross-section and slots are formed on both sides of the connecting frames. A flexible tube is inserted into the inner wall of the discharge port, and connecting brackets are fixedly connected to both sides of the flexible tube. The connecting brackets have an "L" shaped cross-section and their surfaces are inserted into the inner wall of the connecting frames. Two positioning frames are fixedly connected to the arc surface of the connecting ring corresponding to the positions of the connecting frames. The two positioning frames are located on both sides of the connecting frames, and the inner walls of the two positioning frames are slidably connected to the same positioning shaft. The arc surface of the positioning shaft engages with the slots and the inner wall of the connecting brackets. Both ends of the positioning shaft are threadedly connected to extrusion shafts.

[0015] The effect achieved by the above components is as follows: after the mixture is mixed in the mixing tank, it will be discharged through the discharge port at the bottom of the mixing tank. At this time, in order to facilitate the collection and guidance of the mixture at the discharge port, a hose is used to connect and limit the discharge port, which effectively avoids collision between the collection equipment and the mixing tank during collection.

[0016] Preferably, protective rings are fitted on both ends of the positioning shaft, and the surface of the protective rings abuts against one side of the extrusion shaft.

[0017] The effect achieved by the above components is that when the positioning shaft and the extrusion shaft are threaded together, the extrusion shaft can be protected by the protective ring, which effectively prevents the extrusion shaft from loosening and falling off.

[0018] Preferably, the inner wall cross-sectional dimensions of the connecting frame are adapted to the cross-sectional dimensions of the positioning shaft, and the connecting frame is a hard alloy frame.

[0019] The effect achieved by the above components is that the connecting bracket made of hard alloy material can be used for a long time without deformation.

[0020] Compared with related technologies, the mixing and granulation stirring assembly provided by this utility model has the following beneficial effects:

[0021] This utility model provides a mixing and granulation stirring assembly. When operating the entire mixing tank, it is necessary to add auxiliary materials for mixing. At this time, in order to facilitate the connection between the feeding tank and the feed pipe, the feeding tank will move towards the feed pipe and abut against the rotating limiting plate on the surface of the feed pipe. This allows the limiting plate to guide the feeding pipe. At the same time, the limiting plate rotates along the inner wall of the fixed frame with the help of a rotating frame. The rotating frame is stretched and limited by the tensile force generated by the tension spring. By operating the adjustment device, the rotating limiting plate is guided, which helps to quickly fix and protect the position of the feeding tank.

[0022] After the mixture is stirred and mixed in the mixing tank, it will be discharged through the outlet at the bottom of the mixing tank. At this time, in order to facilitate the collection and guidance of the mixture at the outlet, a flexible hose is used to connect and limit the connection of the hose to the outlet. The connecting brackets fixed at both ends of the hose are inserted into the connecting frames on both sides of the connecting ring on the surface of the outlet. Then, the positioning shaft is used to lock and limit the connection of the connecting frame and the connecting bracket to prevent the hose from falling off or loosening. By operating the auxiliary device, it is possible to effectively prevent the collection equipment from colliding with the mixing tank when collecting the mixture. Attached Figure Description

A rotating frame 46 is slidably connected to the inner wall of the limiting frame 44. One end of the rotating frame 46 away from the limiting frame 44 is rotatably connected to the surface of the limiting plate 42. Sliding blocks 48 are fixedly connected to both sides of the rotating frame 46. Sliding grooves 45 are opened on both sides of the inner wall of the limiting frame 44. The wall and the surface of the slider 48 are slidably connected. A tension spring 47 is fixedly connected to the surface of the rotating frame 46 away from the limiting plate 42. The upper end of the tension spring 47 is fixedly connected to the upper end of the inner wall of the limiting frame 44. Both ends of the inner arc surface of the fixed frame 41 are fitted with coil springs 49. The two ends of the coil springs 49 are fixedly connected to the limiting plate 42 and the fixed frame 41 respectively. A friction pad 43 is fixedly connected to the upper surface of the limiting plate 42. The friction pad 43 is a rubber pad. The upper cross section of the limiting plate 42 is arc-shaped. The length of the limiting plate 42 is adapted to the bottom cross section of the feeding tank 6.

[0032] In the embodiments of this utility model, please refer to Figure 4The auxiliary device 5 includes a connecting ring 59, the inner wall of which is fixedly connected to the arc surface of the discharge port 8. Connecting frames 53 are fixedly connected to the two end side walls of the connecting ring 59. The connecting frames 53 have a U-shaped cross-section and slots 58 on both sides. A flexible hose 51 is inserted into the inner wall of the discharge port 8. Connecting brackets 52 are fixedly connected to both sides of the flexible hose 51. The connecting brackets 52 have an L-shaped cross-section and their surfaces are inserted into the inner wall of the connecting frame 53.

The two positioning frames 55 are located on opposite sides of the connecting frame 53, and the inner walls of the two positioning frames 55 are slidably connected to the same positioning shaft 54. The arc surface of the positioning shaft 54 ​​engages with the inner wall of the slot 58 and the connecting frame 52. Both ends of the positioning shaft 54 ​​are threaded with the extrusion shaft 57. Both ends of the positioning shaft 54 ​​are fitted with protective rings 56. The surface of the protective ring 56 abuts against one side of the extrusion shaft 57.

[0033] The working principle of the mixing and granulation stirring assembly provided by this utility model is as follows: When the mixing tank 3 is used, in order to facilitate better guidance and docking between the feeding tank 6 and the feed pipe 9, the limiting plate 42 rotating on the surface of the feed pipe 9 is used. When the feeding tank 6 moves towards the feed pipe 9 for docking, it will be guided by the limiting plate 42 with an arc-shaped cross section. At the same time, the surface of the limiting plate 42 slides against the inner wall of the limiting frame 44 through the rotating frame 46. During this process, the upper end of the rotating frame 46 is stretched and limited by the tensile force generated by the tension spring 47, which controls the deflection of the entire limiting plate 42. Meanwhile, the sliders 48 on both sides of the rotating frame 46 will slide along the sliding grooves 45 opened in the limiting frame 44 to prevent one end of the rotating frame 46 from falling off the limiting frame 44.

[0034] After the mixture is stirred and mixed in the mixing tank 3, it will be discharged through the discharge port 8 at the bottom of the mixing tank 3. At this time, in order to facilitate the collection and guidance of the mixture at the discharge port 8, the hose 51 is first connected and fixed to the discharge port 8. Then, the connecting brackets 52 fixed at both ends of the hose 51 are inserted into the connecting frames 53 on both sides of the connecting ring 59 on the surface of the discharge port 8. Then, the positioning shaft 54 ​​in the sliding positioning frame 55 is locked and fixed between the positioning shaft 54 ​​and the slots 58 on both sides of the connecting frame 53 and the connecting bracket 52. Then, the extrusion shafts 57 at both ends of the positioning shaft 54 ​​are extruded to prevent the entire positioning shaft 54 ​​from falling off and loosening. This effectively uses the hose 51 to guide and collect the mixture, while avoiding collisions between the collection equipment and the mixing tank 3.
