Description
Technical Field
[0001] This utility model relates to the field of capsule drug raw material mixing technology, and in particular to a multi-raw material mixer for capsule drug preparation. Background Technology
[0002] In the capsule drug manufacturing process, the uniform mixing of multiple raw materials is the core step to ensure the accurate proportion of drug components and the stable efficacy. Capsule drug raw materials often contain a variety of materials such as active drug ingredients, fillers, and binders. Some of these materials have characteristics such as large density differences, uneven particle size, or slight viscosity. Traditional stirring-type mixing equipment is prone to insufficient mixing due to dead zones, while ordinary tilting-type mixing equipment is difficult to adapt to the complex mixing requirements of multiple raw materials. Therefore, there is an urgent need for a multi-raw material mixer that combines efficient tilting mixing capability with targeted anti-clogging and sealing design. Through the reciprocating rotation of the V-shaped mixing cylinder, sufficient convection, diffusion, and shearing of materials are achieved within the cylinder, improving the mixing uniformity of multiple raw materials. At the same time, it meets the pharmaceutical industry's requirements for equipment cleanliness and ease of operation, providing equipment support for the large-scale, high-quality production of capsule drugs. In existing capsule drug raw material mixing devices, when the mixing drum completes one full rotation, the material tends to accumulate at the discharge pipe at the bottom of the mixing drum due to its own gravity and rotational inertia. Furthermore, the compression during rotation can cause the material inside the discharge pipe to be compacted, forming dense clumps. This compaction directly affects the butterfly valve inside the discharge pipe, potentially causing jamming between the valve core and seat, preventing the valve from opening or closing properly. It can also block the discharge channel, preventing the mixed material from being discharged smoothly, requiring frequent shutdowns for disassembly and cleaning, severely impacting production continuity. Therefore, improvements are needed to address these issues. Utility Model Content

[0006] Preferably, the anti-clogging component includes a rotating rod, one end of which passes through the fixed cylinder and extends into the discharge pipe inside the V-shaped mixing cylinder. The outer wall of the rotating rod has multiple receiving slots equidistantly opened on the circumference of the rod body of the discharge pipe. Multiple crossbars are fixedly connected equidistantly in the receiving slots. A tapered rod is rotatably sleeved on the middle of the crossbar.
[0007] Preferably, torsion springs are sleeved at both ends of the crossbar, and the lever arms of the two torsion springs abut against the outer walls of the upper and lower ends of one end of the cone rod, respectively, and the bottom end of the receiving groove passes through the bottom end of the rotating rod.
[0008] Preferably, a fixing box sleeved on the rotating rod is bolted to the top surface of the mounting plate, a lifting plate is fixed to the bottom surface of the rotating rod at the bottom of the fixing cylinder, a rotating disk is rotatably provided on the top surface of the lifting disk, a spring is fixed to the top surface of the rotating disk, and the top end of the spring is fixed to the bottom surface of the fixing box.
[0009] Preferably, a handwheel is coaxially fixed to the top of the rotating rod, and a limit plate is fixed to the top surface of the fixed box on the rotating rod.

This enables rapid disassembly and thorough cleaning of the anti-clogging component. Ultimately, this solves the problem of material compaction causing blockage of the discharge pipe and the inability of the butterfly valve to open properly in existing devices, improving production continuity and operational convenience.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 5This utility model discloses a multi-raw material mixer for capsule drug preparation, comprising a base plate 1, a vertical plate fixedly connected to one side of the top surface of the base plate 1, and an electrical cabinet 2 fixedly connected to the other side of the top surface of the base plate 1. A control panel is installed on the door of the electrical cabinet 2. A V-shaped mixing cylinder 3 is rotatably mounted between the electrical cabinet 2, the vertical plate, and the opposite side of the electrical cabinet 2. A reducer is installed inside the electrical cabinet 2 and coaxially fixedly connected to one side of the rotating shaft of the V-shaped mixing cylinder 3. A driven pulley is coaxially fixedly connected to the input shaft of the reducer. A motor is installed on the bottom surface of the electrical cabinet 2, and a driving pulley is coaxially fixedly connected to the output shaft of the motor. A transmission belt is installed between the driven pulley and the driving pulley. A discharge pipe 4 is connected to the flange at the middle of the bottom end of the V-shaped mixing cylinder 3, and a butterfly valve is installed inside the discharge pipe 4. The V-shaped mixing cylinder 3 is located at the upper end. A mounting plate 5 is fixedly connected at the angle between two inclined mixing cylinders. A fixed cylinder 6 extending into the inner wall of the V-shaped mixing cylinder 3 is fixedly connected to the bottom surface of the mounting plate 5. An anti-clogging component is installed inside the mounting plate 5. Feed inlets are symmetrically opened on both sides of the top surface of the V-shaped mixing cylinder 3. The bottom plate 1, vertical plate, electrical cabinet 2, V-shaped mixing cylinder 3, mounting plate 5, and fixed cylinder 6 are all made of 304 stainless steel. 304 stainless steel has strong corrosion resistance and high hygiene, meeting the strict requirements of the pharmaceutical industry for equipment materials. It can also improve the overall structural strength and avoid deformation after long-term use. The motor is a Y2-132M-4 three-phase asynchronous motor, which has stable power and is suitable for mixing requirements. The reducer is a WP series worm gear reducer, which can reduce the motor speed and increase torque. The material is transferred to the V-shaped mixing drum 3 to ensure smooth reciprocating rotation and thorough mixing of multi-component raw materials. The discharge pipe 4 and butterfly valve facilitate precise control of material discharge timing. The mounting plate 5 and fixed cylinder 6 provide a stable mounting carrier for the anti-clogging components. The above components together form the basic framework of the device, meeting the material standards of the pharmaceutical industry while ensuring the basic mixing and discharge functions of the equipment. A hinge seat is fixed to one side of the V-shaped mixing drum 3 at the discharge port. A cover plate 7 is fixed to the rotating shaft of the hinge seat. Two fixed plates are symmetrically fixed to the outer wall of the cover plate 7 away from the hinge seat. A mating plate corresponding to the gap between the two fixed plates is fixed to the other side of the V-shaped mixing drum 3 at the discharge port. A screw thread is coaxially opened between the fixed plate and the mating plate. The cover plate 7 has a perforated and threaded hole with a fixing bolt screwed into it. A protruding post is fixed to the bottom surface of the cover plate 7. Multiple sealing rings are fixed to the outer wall of the protruding post at equal intervals along the axial direction. The inner wall of the V-shaped mixing cylinder 3 has a sealing groove corresponding to the sealing rings. The cover plate 7 is made of 304 stainless steel, which is the same material as the V-shaped mixing cylinder 3 to ensure uniform corrosion resistance and structural compatibility. The sealing rings are made of food-grade silicone. Food-grade silicone has strong sealing performance, a wide temperature range, and no harmful substances are released. It can prevent material leakage or external impurities from entering during the mixing process, and at the same time prevent contamination of the drug raw materials. The fit between the hinge seat and the cover plate 7 facilitates quick opening and closing of the feed port. The combination of the fixing plate, the docking plate, and the fixing bolts can firmly fix the cover plate 7 to prevent it from loosening when the V-shaped mixing cylinder 3 rotates.The above improvements enhance the equipment's sealing reliability and ease of operation, while also meeting pharmaceutical industry hygiene standards. The anti-clogging component includes a rotating rod 8, one end of which passes through the fixed cylinder 6 and extends into the discharge pipe 4 inside the V-shaped mixing cylinder 3. Multiple receiving slots 9 are equidistantly spaced along the outer wall of the rotating rod 8 around the discharge pipe 4. Multiple crossbars are equidistantly fixed within the receiving slots 9, and a tapered rod 10 is rotatably sleeved on the middle of each crossbar. Both the rotating rod 8 and the tapered rod 10 are made of 304 stainless steel, which is high in hardness and has a smooth surface. It is easy to clean and can withstand the forces during material compression and crushing, preventing deformation or corrosion. The rotating rod 8 can drive the cone rod 10 to move inside the discharge pipe 4, the receiving groove 9 provides storage space for the cone rod 10, and the crossbar allows for flexible rotation and installation of the cone rod 10. The sharp structure of the cone rod 10 can effectively break up compacted material clumps inside the discharge pipe 4, preventing blockage. Through the above, a targeted anti-blocking function is achieved for the discharge pipe 4, ensuring the smooth discharge of mixed materials, while the material properties reduce the difficulty of cleaning.
[0015] In this invention, torsion springs 11 are sleeved at both ends of the crossbar. The lever arms of the two torsion springs 11 are located at the upper and lower outer walls of one end of the cone rod 10, respectively, and the bottom end of the receiving groove 9 passes through the bottom end of the rotating rod 8. The torsion springs 11 are made of spring steel, which has excellent elastic recovery ability and fatigue strength, and can maintain stable elastic force for a long time, avoiding elastic force attenuation after frequent use. The lever arms of the torsion springs 11 abut against both ends of the cone rod 10, and can automatically pop out of the receiving groove 9 when the cone rod 10 is not squeezed by external force, ensuring the crushing efficiency of material agglomeration. At the same time, when the cone rod 10 is squeezed by the inner wall of the fixed cylinder 6, it can flexibly retract into the receiving groove. The storage slot 9 facilitates the disassembly and assembly of the anti-clogging component; the bottom of the storage slot 9 is through-hole set to provide ample space for the pop-out and retraction of the cone rod 10, avoiding jamming; the above features improve the reliability and flexibility of the cone rod 10's operation, further enhancing the practicality of the anti-clogging component; a fixing box 12 is bolted to the top surface of the mounting plate 5 and sleeved on the rotating rod 8; a lifting plate is fixed to the bottom surface of the rotating rod 8 inside the fixing cylinder 6; a rotating disc is rotatably mounted on the top surface of the lifting disc; a spring 13 is fixed to the top surface of the rotating disc; the top of the spring 13 is fixed to the bottom surface of the fixing box 12; the fixing box 12 is made of 304 stainless steel, and... Mounting plate 5 is made of the same material, has strong adaptability and corrosion resistance, and the bolt connection method facilitates disassembly, providing convenience for cleaning and maintenance of the anti-clogging component; spring 13 is made of spring steel, with stable elasticity, and can automatically reset after manual lifting of rotating rod 8, reducing operation steps and improving convenience; the cooperation between the lifting plate and the rotating plate ensures that spring 13 does not rotate with rotating rod 8, avoiding spring 13 winding and deformation, and extending service life; the above features improve the ease of disassembly and assembly and structural stability of the anti-clogging component, and reduce equipment maintenance costs; a handwheel is coaxially fixed to the top of rotating rod 8, and the rotating rod... A limiting plate is fixedly attached to the top surface of the fixed box 12. Both the handwheel and the limiting plate are made of 304 stainless steel with a smooth surface that is easy to clean and does not easily breed bacteria, meeting the hygiene requirements of the pharmaceutical industry. The handwheel increases the operating torque of the rotating rod 8, allowing operators to rotate the rotating rod 8 with less effort and reducing operational intensity. The limiting plate effectively limits the downward movement range of the rotating rod 8, preventing it from falling directly into the V-shaped mixing cylinder 3 due to improper operation, thus avoiding equipment failure or raw material contamination. The above features improve the safety and convenience of equipment operation and ensure the stability of the production process.
[0016] Working Principle: When using this utility model, firstly, remove the fixing bolts between the outer wall fixing plate of the cover plate 7 and the connecting plate of the V-shaped mixing cylinder 3, flip the cover plate 7 around the hinge seat to open it, and put the required multi-component raw materials into the feed inlets on both sides of the top surface of the V-shaped mixing cylinder 3. After the feeding is completed, close the cover plate 7, so that the sealing ring of the outer wall of the protruding column on the bottom surface of the cover plate 7 is embedded into the sealing groove of the inner wall of the V-shaped mixing cylinder 3 to form a multiple seal. Then, re-tighten the fixing bolts to achieve a sealed and fixed feed inlet to prevent subsequent raw material leakage or impurity intrusion. Next, the operator starts the equipment through the control panel of the electrical cabinet 2 door. The motor on the bottom surface of the electrical cabinet 2 is powered on and runs. The output shaft drives the coaxially fixed drive pulley to rotate. The drive pulley drives the driven pulley to rotate synchronously via a transmission belt. The driven pulley drives the input shaft of the reducer to rotate. After the reducer reduces speed and increases torque, the power is transmitted to the rotating shaft on one side of the V-shaped mixing drum 3, causing the V-shaped mixing drum 3 to reciprocate around the rotating shaft between the vertical plate and the electrical cabinet 2. Under the guidance of the double inclined drum cavity, the multi-component raw materials inside the drum continuously convect, diffuse, and shear, breaking up the agglomeration state and achieving uniform mixing. If, during or after mixing, the material accumulates and compacts towards the discharge pipe 4 at the bottom of the V-shaped mixing drum 3, the motor driving the rotation of the V-shaped mixing drum 3 is stopped, and the operator can turn the drum around. The handwheel at the top of the rotating rod 8 drives the rotating rod 8 to rotate. At the same time, the rotating rod 8 is manually pulled upwards to overcome the elastic force of the spring 13 and move up and down. The limiting plate at the top of the rotating rod 8 can prevent the rotating rod 8 from falling directly into the V-shaped mixing cylinder 3. At this time, the cone rod 10 located on the outer wall of the rotating rod 8 inside the discharge pipe 4 is ejected from the receiving groove 9 under the elastic force of the torsion spring 11. With the rotation and movement of the rotating rod 8, the compacted material is broken and dispersed to prevent agglomeration and blockage. After the material is loosened, the butterfly valve in the discharge pipe 4 is opened, and the evenly mixed raw material is discharged through the discharge pipe 4. When cleaning the anti-blockage component after the discharge is completed, first remove the fixing box 12 on the top surface of the mounting plate 5. The bolts are loosened, and the rotating rod 8 is pulled upwards, causing the spring 13, lifting plate, and cone rod 10 to be removed from the fixed cylinder 6 and V-shaped mixing cylinder 3. After cleaning, the rotating rod 8 is inserted into the cylinder. When the cone rod 10 touches the bottom surface of the fixed cylinder 6, it will automatically rotate around the axis and be stored in the storage groove 9. After the lifting plate is reset, the fixed box 12 is re-fixed with bolts. At this time, the cone rod 10 pops out of the storage groove 9 under the elastic force of the torsion spring 11, restoring the anti-blocking function and waiting for the next use. Throughout the process, the base plate 1 provides stable support for the upright plate, electrical cabinet 2, and other components, ensuring the overall stability of the equipment. The device is now in use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
