[0040] See also Figures 1 to 5 The embodiment of the present disclosure provides a mixing and stirring device for pharmaceutical production, including: a stirring barrel 3, a cover plate 5, a support base 1, a support frame 101 and a stirring device 4.
[0041] like Figure 4 As shown, the mixing barrel 3 is a hollow member with an open top. Figure 1 , Figure 2 and Figure 4 The mixing barrel 3 is shown to be roughly cylindrical, and it is understandable that the mixing barrel 3 may also be square, conical or other shapes. The cover plate 5 covers the top opening of the mixing barrel 3 to seal the space inside the mixing barrel 3 to prevent the material inside the mixing barrel 3 from splashing out.
[0042] like Figures 1 to 3 As shown, the support base 1 is located below the mixing barrel 3, and the support frame 101 is connected to the support base 1 and the mixing barrel 3 respectively. The support base 1 and the support frame 101 support the mixing barrel 3. Among them, the support base 1 can be placed on a bearing surface. The bearing surface includes but is not limited to the ground. The support frame 101 is arranged roughly in the vertical direction, and the mixing barrel 3 is installed on the support frame 101, so that the mixing barrel 3 can be kept away from the supporting surface.
[0043] like Figure 4 and Figure 5As shown, the stirring device 4 includes a first motor assembly 401, a first stirring rod 403, a second motor assembly 503 and a second stirring rod 505; wherein the first stirring rod 403 includes: a first part 404 and a second part 405, the first part 404 is in contact with the bottom wall of the stirring barrel 3, the second part 405 is connected to the first part 404 and in contact with the side wall of the stirring barrel 3, the first motor assembly 401 is connected to the first stirring rod 403 to drive the first part 404 and the second part 405 to rotate synchronously; the second stirring rod 505 extends from the cover plate 5 to the bottom wall of the stirring barrel 3, and has a gap between it and the first stirring rod 403; the second motor assembly 503 is connected to the second stirring rod 505, the first motor assembly 401 and the second motor assembly 503 are respectively electrically connected to the controller, so as to realize the synchronous rotation of the first stirring rod 403 and the second stirring rod 505 through the controller.
[0044] Without limitation, the first motor assembly 401 and the second motor assembly 503 may be electrically connected to each other by a controller, and control instructions may be sent to the first motor assembly 401 and the second motor assembly 503 by the controller to achieve synchronous rotation of the first stirring rod 403 and the second stirring rod 505 .
[0045] The first portion 404 of the first stirring rod 403 can improve the stirring effect on the material at the bottom of the stirring barrel 3 and reduce the adhesion of the material to the bottom wall of the stirring barrel 3. The second portion 405 of the first stirring rod 403 can improve the stirring effect on the material on the side wall of the stirring barrel 3, and the connection between the first portion 404 and the second portion 405 can fully stir the material at the corner of the side wall and the bottom wall of the stirring barrel 3, further reducing the adhesion of the material at the side wall and the bottom corner of the stirring barrel 3, and improving the stirring efficiency.
[0046] The second stirring rod 505 can better stir the materials in the space above the stirring barrel 3. When the first stirring rod 403 and the second stirring rod 505 rotate synchronously, all the materials in the stirring barrel 3 can be stirred more fully, further improving the stirring efficiency and reducing the adhesion of the materials.
[0047] like Figure 4 As shown, the first stirring rod 403 is L-shaped, and the number of the first stirring rod 403 can be multiple. The multiple first stirring rods 403 are distributed along the circumference of the stirring barrel 3, which can further improve the stirring effect. Figure 4 Four L-shaped first stirring rods 403 are shown by way of example. It is understandable that the number of the first stirring rods 403 may be 2, 3, 6 or more.
[0048] Figure 5Two second stirring rods 505 are shown as examples, and the second stirring rods 505 are spiral stirring rods extending axially along the stirring barrel 3. It is understandable that the number of the second stirring rods 505 can also be three, four, six or more. The second stirring rods 505 are also not limited to spiral stirring rods.
[0049] Figure 1 The schematic diagram of the structure of the mixing and stirring device 4 is exemplarily shown when the movable part 202 is in the stirring position.
[0050] Combination Figure 1 As shown, according to some optional embodiments, the mixing and stirring device 4 further includes: a limiting device 2, fixed to the support frame 101; the limiting device 2 includes a fixed part 201 and a movable part 202, and the movable part 202 can switch between a stirring position and a discharging position relative to the fixed part 201; wherein, when the movable part 202 is in the stirring position, the movable part 202 is in a locked state to fix the mixing barrel 3 together with the fixed part 201. When the movable part 202 is in the discharging position, the movable part 202 is in an unlocked state, and the mixing barrel 3 can rotate relative to the support frame 101 to discharge the material in the mixing barrel 3.
[0051] When stirring is required, the movable part 202 can squeeze the stirring barrel 3 between the movable part 202 and the fixed part 201 to prevent the stirring barrel 3 from rotating, thereby ensuring the stability of the mixing and stirring device 4 during the stirring process. When stirring is completed and the material needs to be discharged, the movable part 202 can be unlocked, for example, the movable part 202 can be removed from the fixed part 201, or the movable part 202 can be repositioned to increase the space between the movable part 202 and the fixed part 201, so that the stirring barrel 3 can rotate relative to the support frame 101 to dump the material.
[0052] By utilizing the switching of the movable part 202 between the stirring position and the discharging position, and the characteristic that the stirring barrel 3 can rotate relative to the support frame 101, both stirring and discharging are facilitated, thereby improving stirring efficiency and user experience.
[0053] like Figures 1 to 3 As shown, without limitation, the fixed member 201 is a fixed semi-ring, the movable member 202 is a movable semi-ring, and when the movable member 202 is in the stirring position, the movable member 202 and the fixed member 201 together form a circular ring surrounding the outer circumference of the stirring barrel 3 .
[0054] When the movable part 202 is in the material discharging position, the movable part 202 and the fixed part 201 cannot form a ring together, and the mixing barrel 3 cannot be locked, so the mixing barrel 3 can rotate to dump the material.
[0055] Optionally, one end of the movable member 202 is pivotally connected to the fixed member 201 , and the other end of the movable member 202 is detachably connected to the fixed member 201 .
[0056] When the movable member 202 is in the stirring position, the other end of the movable member 202 is connected to the fixed member 201 to form a ring around the outer circumference of the stirring barrel 3 together with the fixed member 201. When the movable member 202 is in the discharging position, the other end of the movable member 202 is separated from the fixed member 201, and the movable member 202 is pivotally connected to the fixed member 201 to position the rotating axis of the movable member 202 so as not to interfere with the pouring of materials from the stirring barrel 3.
[0057] According to some optional embodiments, Figure 3 As shown, the mixing and stirring device 4 further includes: a movable shaft 102 , which is mounted on the support frame 101 and connected to the mixing barrel 3 , so that the mixing barrel 3 can rotate relative to the support frame 101 .
[0058] Two movable shafts 102 may be symmetrically arranged on the mixing barrel 3 in the circumferential direction to improve the rotation stability of the mixing barrel 3 and improve the reliability of the connection between the mixing barrel 3 and the support frame 101 .
[0059] like Figure 1 and Figure 2 As shown, according to some optional embodiments, the mixing and stirring device 4 further includes: a push rod 302 and two grip rods 303 , one end of the push rod 302 is fixed to the mixing barrel 3 , and the other end of the push rod 302 is connected to the two grip rods 303 .
[0060] When dumping materials, the operator can hold the handle 303 and apply a rotational external force to the mixing barrel 3 to realize the rotational discharge of the mixing barrel 3, which is convenient and practical.
[0061] In some optional embodiments, an electrically driven driving device may be connected to the mixing barrel 3 to automatically drive the mixing barrel 3 to rotate electrically to achieve automatic discharging.
[0062] like Figure 1 and Figure 5 As shown, according to some optional embodiments, the cover plate 5 includes a fixed cover plate 501 and a movable cover plate 502, and the movable cover plate 502 is hinged to the fixed cover plate 501. When the movable cover plate 502 is in an open state, the mixing barrel 3 can discharge materials through its top opening. When discharging materials, the cover plate 5 of this structure does not need to open all the cover plates 5, but only needs to open the movable cover plate 502, which is more labor-saving.
[0063] like Figure 5As shown, according to some optional embodiments, the second motor assembly 503 is fixed to the outside of the fixed cover plate 501, and the first stirring rod 403 extends toward the bottom wall of the stirring barrel 3 after passing through the fixed cover plate 501 from the first motor group. The fixed cover plate 501 can be used as a carrier for mounting and fixing the second motor assembly 503. Combined with the overall structure of the cover plate, when discharging, since the second motor assembly 503 is fixed on the fixed cover plate 501, it is not necessary to lift the fixed cover plate 501, and only the movable cover plate 502 needs to be lifted, which further ensures the convenience of discharging.
[0064] like Figure 2 As shown, according to some optional embodiments, the first motor assembly 401 is fixed to the outer side of the bottom wall of the mixing barrel 3, and is spaced apart from the bearing surface of the bearing support base 1. The first motor assembly 401 is fixed by fully utilizing the structure of the mixing barrel 3 itself, which not only improves the utilization rate of the mixing barrel 3, but also makes full use of the height space and reduces the radial space occupied by the mixing and stirring device 4.
[0065] In a specific example, refer to Figures 1 to 5 As shown, the support frame is two support rods evenly spaced along the circumference of the support base. The support rods are fixedly mounted with a movable shaft 102 toward the inner side of the mixing barrel. The movable shaft 102 can be mounted inside the movable groove 301 through a bearing to facilitate the rotation of the mixing barrel 3.
[0066] The bottom side of the fixed half ring is fixedly installed on the top of the two support rods 101, one end of the fixed half ring is connected to the movable half ring through a movable shaft, the other end of the fixed half ring is provided with a limiting groove 203, and a limiting rod 204 is fixedly installed on the inner side of one end of the movable half ring, and the surface of the limiting rod 204 is movably embedded in the inside of the limiting groove 203.
[0067] One end of the movable half ring is connected to the fixed half ring through a movable shaft for easy rotation. The fixed half ring and the movable half ring limit the mixing barrel 3. The movable half ring is embedded in the limiting groove 203 through a limiting rod 204 for limiting and fixing.
[0068] Movable grooves 301 are provided on both sides of the surface of the mixing barrel 3, and one end of the two movable shafts 102 are respectively embedded in the inside of the two movable grooves 301 through bearings. A push rod 302 is fixedly installed on the top of one side surface of the mixing barrel 3, and two grip rods 303 are fixedly installed on one end of the push rod 302.
[0069] The movable groove 301 is arranged near the center of the mixing barrel 3, which is convenient for saving effort when pouring the raw materials. The push rod 302 and the grip rod 303 are convenient for pushing the mixing barrel 3 when discharging the materials.
[0070] Combination Figure 4As shown, one side of the first motor assembly 401 is fixedly installed on the bottom of the mixing barrel 3, and the output end of the first motor assembly 401 is installed with a connecting shaft 402 through a bearing penetrating the bottom of the mixing barrel 3, and four first stirring rods 403 are fixedly installed on the surface of the connecting shaft 402, and the four first stirring rods 403 are all L-shaped stirring rods.
[0071] After the first motor assembly 401 is started, it will drive the connecting shaft 402 and the first stirring rod 403 to rotate and stir the raw materials, and simultaneously drive the L-shaped first stirring rod 403. The bottom side of the L-shaped first stirring rod 403 can enhance the stirring effect, and the upright side fits against the inner wall of the stirring barrel 3. While stirring the raw materials, it can prevent the raw materials from adhering to the inner wall of the stirring barrel 3. When discharging, the first motor assembly 401 can also be started to drive the L-shaped first stirring rod 403, which can speed up the discharging speed on the one hand and prevent the raw materials from sticking on the other hand.
[0072] like Figure 5 As shown, the bottom side of the fixed cover plate 501 is fixedly installed on the top of the mixing barrel 3, one side of the fixed cover plate 501 is connected to the movable cover plate 502 by a hinge, the bottom of the movable cover plate 502 is movable on the top of the mixing barrel 3, and the second motor assembly 503 is fixedly installed on the surface of the fixed cover plate 501, and the output ends of the second motor assembly 503 are both installed with connecting rods 504 through bearings penetrating the surface of the fixed cover plate 501, and the bottom ends of the two connecting rods 504 are fixedly connected to the second stirring rods 505, and the two second stirring rods 505 are both movable inside the mixing barrel 3.
[0073] The movable cover plate 502 is connected to the fixed cover plate 501 by a hinge for easy opening and closing. After the second motor assembly 503 is started, it drives the connecting rod 504 and the second stirring rod 505 to rotate, thereby increasing the mixing rate of the raw materials inside the stirring barrel 3.
[0074] Working principle: When using this device for mixing and stirring raw materials in pharmaceutical production, first open the movable cover 502, pour the raw materials into the mixing barrel 3, then cover the movable cover 502, and then connect the external power supply to the first motor component 401 and the second motor component 503 and use the external controller to start. After the first motor component 401 is started, it will drive the linkage shaft 402 and the first stirring rod 403 to rotate and stir the raw materials. The bottom side of the L-shaped first stirring rod 403 can enhance the stirring effect, and the upright side fits the inner wall of the mixing barrel 3. While stirring the raw materials, it can prevent the raw materials from adhering to the inner wall of the mixing barrel 3. After starting, the second motor component 503 will drive the connecting rod 504 and the second stirring rod 505 to rotate, mix and stir the raw materials inside the mixing barrel 3, and through multiple stirring methods, the mixing and stirring of the raw materials can be completed efficiently.
[0075] After the mixing is completed and the material is to be discharged, the second motor assembly 503 and the first motor assembly 401 are stopped first, then the movable cover plate 502 is opened, and one end of the movable semi-ring is lifted and rotated 180 degrees to make the limit rod 204 leave the inside of the limit groove 203, and then the grip rod 303 is held to push the push rod 302 to make the mixing barrel 3 rotate around the movable shafts 102 on both sides, so that the mixed raw materials inside are poured into the external collecting device. During the discharging process, the first motor assembly 401 can be started to rotate the L-shaped first stirring rod 403 to prevent the raw materials from adhering to the inner wall of the mixing barrel 3 and assist the discharging work. By rotating the mixing barrel 3 to pour the material and assisting the L-shaped first stirring rod 403, the discharging efficiency is improved while avoiding the adhesion of the raw materials.
