Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical granulation, and specifically relates to a granulator with automatic adjustment of roll gap. Background Art

[0002] Dry granulation is a granulation process commonly used in the pharmaceutical and chemical industries, especially when water or organic solvents cannot be used. This process aggregates powder materials into granules through mechanical force and is commonly used in the production of solid dosage forms in the pharmaceutical industry, such as the preparation of tablets or capsules. Many of our company's leading products apply this technology during the production process. Dry granulation has some advantages compared to wet granulation, such as avoiding the decomposition of easily hydrolyzable active ingredients in drugs, controlling the content of related substances, improving product stability, simplifying subsequent drying steps, and enhancing production efficiency.

[0003] Traditional pharmaceutical granulation processes often rely on the experience accumulation of technicians, with low automation and key parameters being difficult to quantify. This not only increases the complexity of operation but also easily leads to human errors, thereby affecting the uniformity of products and being unfavorable for product quality control. In addition, traditional granulation processes are relatively weak in controlling the thickness and morphology of granules, and it is easy to have uneven granule morphology, which affects product quality control and subsequent applications.

[0040] Please refer to the appendix Figure 1 - Appendix Figure 7, the preliminary screening mechanism 6 is located on the suspension frame 2 and cooperates with the feeding frame 132 and the extension arm 613 to screen the flotation chemical raw materials. The preliminary screening mechanism 6 includes a flotation tank 61, a material guiding inclined plate 62, a grid pushing plate 616, a lever 617, a reset guiding component, a liquid level control component and a displacement driving component. The flotation tank 61 is fixedly connected to the top of the suspension frame 2. The material guiding inclined plate 62 is fixedly connected to the side wall of the flotation tank 61 close to the receiving chute 5. The reset guiding components are two groups and are arranged on both sides of the flotation tank 61 at the same time. The liquid level control component is arranged on the side wall of the flotation tank 61. The displacement driving component is arranged on the side wall of the flotation tank 61. The grid pushing plate 616 is arranged between the two reset guiding components. The levers 617 are evenly linearly distributed on the top of the grid pushing plate 616. The reset guiding component includes a trapezoidal chute 611, a limit clamping column 612, an extension arm 613, a linear limit groove 614 and a suspension arm 615. The trapezoidal chute 611 is arranged on the upper part of the inner side wall of the flotation tank 61. The extension arm 613 is slidably connected to the top wall of the flotation tank 61. A clamping rail is arranged on the side wall of the extension arm 613 away from the flotation tank 61. The linear limit groove 614 is arranged on the extension arm 613. The limit clamping columns 612 are respectively slidably connected inside the trapezoidal chute 611 and the linear limit groove 614. The suspension arm 615 is slidably connected in the clamping rail of the extension arm 613. One end of the limit clamping column 612 away from the flotation tank 61 is rotatably connected to the top end of the output motor two 65. The grid pushing plate 616 is fixedly connected to the bottom end of the suspension arm 615. The displacement driving component includes a fixed frame 63, a displacement screw 64, an output motor two 65 and a nut pair limit frame 610. The fixed frame 63 is fixedly connected to the side wall of the flotation tank 61. The displacement screw 64 is rotatably connected inside the fixed frame 63. The output motor two 65 is fixedly connected to the side wall of the fixed frame 63. One end of the displacement screw 64 is fixedly connected to the output end of the output motor two 65. A nut pair limit frame 610 is threadedly connected to the outside of the displacement screw 64. The nut pair limit frame 610 is fixedly connected to one side extension arm 613. First, the preliminary screening mechanism 6 conducts a preliminary screening operation on the added chemical raw materials, uses the buoyancy of the raw material powder to separate other impurities contained therein, and drives the preliminary screening mechanism 6 to start operating. The preliminary screening mechanism 6 contained in the preliminary screening mechanism 6 is arranged above the suspension frame 2, and it bears the water that can be used for flotation through its own morphological structure. At the same time, the liquid level control component contained in the preliminary screening mechanism 6 is used for water replenishment. The induction gasket 68 contained in the liquid level control component continuously operates. The extension frame 66 is fixed to the side wall of the flotation tank 61, and its internal cavity has the same height as the pool wall of the flotation tank 61. The external water filling device injects water into the flotation tank 61 along the filling pipe 69. Among them, the induction gasket 68 continuously opens without any external force contact, so that the filling pipe 69 can continuously supply water. The water supplied into the flotation tank 61 can enter the inside of the extension frame 66 through the mesh grille installed on the side wall of the extension frame 66. As the water enters, the water level inside the extension frame 66 continuously rises.Thus, the buoyancy contact member 67 inside the extension frame 66 floats upward until the buoyancy contact member 67 rises to the highest position inside the cavity of the extension frame 66, which is also the highest storage position of the flotation tank 61. The buoyancy contact member 67 touches the induction gasket 68, causing it to close, thereby stopping the water replenishment of the filling pipe 69. When the chemical raw materials fall into the flotation tank 61, the displacement drive assembly included in the preliminary screening mechanism 6 is synchronously started. After the output motor two 65 included in the displacement drive assembly starts, it generates a rotational drive torque to synchronously drive the displacement screw 64 to rotate along the outer wall of the flotation tank 61 on the fixed frame 63. With the rotation of the displacement screw 64, a set of reset guide components fixed to the nut pair limit frame 610 and the nut pair limit frame 610 are driven to perform linear reciprocating displacement along the side wall of the flotation tank 61. Two sets of opposite reset guide components are provided on both sides of the flotation tank 61. While one set follows the displacement of the displacement drive assembly, the other set also follows the displacement synchronously. The trapezoidal chute 611 included in the reset guide component is arranged on the upper part of the inner side wall of the flotation tank 61. At the same time, the limit clamping column 612 included in the reset guide component slides inside the trapezoidal chute 611. When the extension arm 613 of the reset guide component is displaced by the displacement drive assembly, the extension arm 613 drives the limit clamping column 612 and the suspension arm 615 to displace. The limit clamping column 612 then displaces along the internal track of the trapezoidal chute 611. The suspension arms 615 included in the two sets of opposite reset guide components drive the grid push plate 616 and the dial rod 617 installed between them to start linear displacement. When the limit clamping column 612 displaces along the lower track of the trapezoidal chute 611, the limit clamping column 612 will drive the suspension arm 615 to descend along the straight row limit groove 614 provided on the extension arm 613, causing the grid push plate 616 to sink into the flotation tank 61, and the dial rod 617 descends to the storage water level position of the flotation tank 61 for displacement, stirring and evenly spreading the chemical raw materials floating on the storage water surface of the flotation tank 61. The high-density impurities mixed inside the chemical raw materials start to sink to the lower part inside the flotation tank 61 while being stirred, and the chemical raw materials remain on the water surface due to their own density. When the limit clamping column 612 displaces to the end of the lower track of the trapezoidal chute 611, it starts to rise along the trapezoidal chute 611 and reaches the upper track of the trapezoidal chute 611. The limit clamping column 612 then drives the suspension arm 615 to rise along the rail installed on the extension arm 613, and lifts the grid push plate 616 to the storage water surface of the flotation tank 61. At the same time, the displacement drive assembly drives the corresponding extension arm 613 to start reverse displacement, driving the grid push plate 616 to push the chemical raw materials after flotation towards the material guiding inclined plate 62 direction, and finally entering the receiving inclined channel 5 installed on the side wall of the suspension frame 2 along the material guiding inclined plate 62, and being sent into the heating and bearing mechanism 7 by the receiving inclined channel 5 for melting and heating. While the flotation and pushing are in progress, the water level inside the flotation tank 61 will also drop accordingly.Thus, after the buoyancy contact member 67 included in the liquid level control assembly is driven to descend and separate from the induction gasket 68, the induction gasket 68 continues to start water replenishment until the water level inside the flotation tank 61 pushes the buoyancy contact member 67 to float up again and contact the induction gasket 68, thereby achieving the automatic water replenishment ability of the flotation equipment.

[0041] Please refer to the appendix Figure 1 - appendix Figure 7 , the heating and carrying mechanism 7 is located inside the suspension frame 2 and is used in cooperation with the hopper-shaped box 101 to receive the powdered chemical raw materials after flotation. The heating and carrying mechanism 7 includes a heat-insulating tank 71. The discharge guiding pipe 72 is fixedly connected to the bottom wall of the heat-insulating tank 71 away from the receiving ramp 5. Opposite heating elements 73 are arranged on both sides inside the discharge guiding pipe 72. The heat-insulating tank 71 included in the heating and carrying mechanism 7 is fixed inside the suspension frame 2 and its lower part extends into the inside of the hopper-shaped box 101. After the powdered chemical raw materials after flotation enter the heat-insulating tank 71, the output motor 1 installed on the top of the operation frame 1 is started synchronously. The torque generated by the output motor 1 is driven to the mixing and traction mechanism 8 through the bidirectional belt guiding member 4. After the central linkage shaft 81 included in the mixing and traction mechanism 8 receives the torque conducted by the bidirectional belt guiding member 4, it synchronously drives the mixing blades 82 distributed on the side walls. The high-speed rotating mixing blades 82 generate a mixing and stirring force inside the heat-insulating tank 71, causing the powdered chemical raw materials after flotation inside the heat-insulating tank 71 to be mixed and stirred.

[0042] Please refer to the appendix Figure 1 - appendix Figure 8, the mixing and traction mechanism 8 is located inside the heating and bearing mechanism 7 and cooperates with the heat insulation tank 71 to extract the chemical raw material powder after flotation. The mixing and traction mechanism 8 includes a central linkage shaft 81 and a coaxial transmission component. The central linkage shaft 81 is rotatably connected to the inner side wall of the heat insulation tank 71. The coaxial transmission component is arranged on the side wall of the heat insulation tank 71 away from the receiving chute 5. One end of the central linkage shaft 81 away from the receiving chute 5 is fixedly connected to the bottom output wheel of the two-way belt guide 4. The side wall of the central linkage shaft 81 is provided with evenly distributed mixing blades 82. The side wall of the central linkage shaft 81 away from the receiving chute 5 is rotatably connected to a fixed ring frame 83. The side wall of the fixed ring frame 83 is fixedly connected with a suspended spiral piece 84. The suspended spiral piece 84 spirally surrounds the outside of the central linkage shaft 81 and the mixing blades 82. The side wall of the fixed ring frame 83 away from the component box 85 is fixedly connected with evenly distributed paddles 810. The paddles 810 are arranged above the discharge guide pipe 72. The coaxial transmission component includes a component box 85 and a fixed ring frame 83. The central linkage shaft 81 and the component box 85 are coaxially arranged. The central linkage shaft 81 horizontally penetrates the component box 85. The component box 85 is fixedly connected to the inner side wall of the heat insulation tank 71 away from the receiving chute 5. The inner side wall of the component box 85 is rotatably connected with an internal tooth key ring 86. The side wall of the internal tooth key ring 86 is fixedly connected with a T-shaped turntable 87. The fixed ring frame 83 is fixedly connected to the outer side wall of the T-shaped turntable 87. The central drive gear 88 is rotatably connected to the center of the component box 85. The central drive gear 88 is fixedly connected to the outside of the central linkage shaft 81. The annularly distributed intermediate transmission gears 89 are rotatably connected inside the component box 85. The inner tooth keys of the intermediate transmission gears 89 are meshed with the outer tooth keys of the central drive gear 88. The outer tooth keys of the intermediate transmission gears 89 are meshed with the inner tooth keys of the internal tooth key ring 86. When the central linkage shaft 81 rotates, it will drive the coaxial transmission component included in the mixing and traction mechanism 8 to start operating. The component box 85 included in the coaxial transmission component is fixed on the side wall of the heat insulation tank 71. A set of central drive gears 88 is installed in the center of the component box 85 and rotates synchronously with the central linkage shaft 81. At the same time, the intermediate transmission gears 89 are arranged around the central drive gear 88. The internal tooth key ring 86 is inlaid on the inner side wall of the component box 85 and surrounds the intermediate transmission gears 89. When the intermediate transmission gears 89 are driven to rotate by the central drive gear 88, the internal tooth key ring 86 is driven to rotate by the intermediate transmission gears 89. Through the guiding transmission of the intermediate transmission gears 89, the rotational speed of the internal tooth key ring 86 relative to the internal tooth key ring 86 is reduced. The internal tooth key ring 86 then drives the fixed ring frame 83 and the suspended spiral piece 84 located inside the heat insulation tank 71 to rotate through the T-shaped turntable 87. The suspended spiral piece 84 surrounds the outside of the mixing blades 82. The chemical raw material is then melted by being in contact with the high temperature generated by the installed heating element 73. The melted chemical raw material continues to enter the tablet pressing and granulating mechanism 9 along the discharge guide pipe 72. While the suspended spiral piece 84 rotates at high speed,The suspension spiral sheet 84 also rotates slowly along the inner wall of the heat-insulating tank 71, generating a conveying thrust to push the molten and mixed chemical raw materials along the inner side wall of the heat-insulating tank 71 towards the discharge guiding pipe 72 installed at the bottom wall of the heat-insulating tank 71. While melting and mixing, the output of the molten chemical raw materials is carried out synchronously. When the chemical raw materials reach the position of the fixed ring frame 83, the paddle 810 rotating slowly with the fixed ring frame 83 continuously pushes the chemical raw materials into the discharge guiding pipe 72. After the melted chemical raw materials enter the feed pipe 94 included in the tablet pressing and granulating mechanism 9.

A circumferentially distributed cutting knife 913 is fixedly connected to the outer ring part of the annular frame 912. After the melted chemical raw materials enter the feeding pipe 94 included in the tablet pressing and granulating mechanism 9, they enter the internal tube 92 along the feeding pipe 94. The internal tube 92 is arranged inside the external tube 91. At the same time, an overhead partition is arranged between the two, so that a channel structure that can communicate is formed between the two. The low-temperature air is injected into the channel structure by the later added air blowing mechanism, so that the side wall of the internal tube 92 can be continuously cooled. After the chemical raw materials enter the internal tube 92, the rotational torque generated by the output motor 1 3 is transmitted to the feeding linkage shaft 93 located inside the internal tube 92 through the bottom output wheel of the two-way belt guiding component 4, so that the feeding linkage shaft 93 drives the externally installed spiral pushing piece 97 to start rotating and simultaneously generate a thrust, pushing the melted chemical raw materials inside the internal tube 92 towards the series of discharge holes 96 installed at the end of the internal tube 92 and pushing them out along the series of discharge holes 96, and at the same time forming multiple strip-shaped raw materials, which contact the lead-out roller 98 installed in the front fixing frame 95. At the same time, according to the required thickness of the particles, the hydraulic output components 911 installed on the front fixing frame 95 are activated to generate a traction force, driving the pressing moving roller 910 slidably installed on the front fixing frame 95 to move away from or close to the pressing fixed roller 99, so as to automatically control the gap between the two. After the strip-shaped raw materials reach the gap between the pressing moving roller 910 and the pressing fixed roller 99 along the lead-out roller 98, they are extruded into a thin sheet with a certain thickness by the material, and at the same time contact the continuously rotating annular frame 912 on the front fixing frame 95. The cutting knives 913 installed on the periphery of the annular frame 912 continuously and evenly perform a granulating operation on the thin sheet raw materials to form the granular finished products of the chemical agent.

[0044] Working principle: First, the preliminary screening mechanism 6 conducts a preliminary screening operation on the added chemical raw materials. The buoyancy of the raw material powder is used to separate other impurities contained therein, driving the preliminary screening mechanism 6 to start operating. The preliminary screening mechanism 6 is arranged above the suspension frame 2. It bears the water that can be used for flotation through its own morphological structure. At the same time, the liquid level control component included in the preliminary screening mechanism 6 is used for water replenishment. The induction gasket 68 included in the liquid level control component continuously operates. The extension frame 66 is fixed on the side wall of the flotation tank 61, and its internal cavity has the same height as the pool wall of the flotation tank 61. The external water filling device injects water into the flotation tank 61 along the filling pipe 69. Among them, when the induction gasket 68 is continuously turned on without any external force contact, the filling pipe 69 can continuously supply water. The water supplied into the flotation tank 61 can enter the inside of the extension frame 66 through the mesh grille installed on the side wall of the extension frame 66. As the water enters, the water level inside the extension frame 66 continuously rises, driving the buoyancy contact member 67 inside the extension frame 66 to float until the buoyancy contact member 67 rises to the highest position inside the cavity of the extension frame 66, that is, the highest storage position of the flotation tank 61. The buoyancy contact member 67 touches the induction gasket 68, causing it to close, thereby stopping the water replenishment of the filling pipe 69. When the chemical raw materials fall into the flotation tank 61, the displacement drive component included in the preliminary screening mechanism 6 is synchronously turned on. After the output motor two 65 included in the displacement drive component starts, it generates a rotational drive torque to synchronously drive the displacement screw 64 to rotate along the fixed frame 63 on the outer wall of the flotation tank 61. As the displacement screw 64 rotates, it drives the nut pair limit frame 610 docked with it and a set of reset guiding components fixed to the nut pair limit frame 610 to perform linear reciprocating displacement along the side wall of the flotation tank 61. Two sets of opposite reset guiding components are arranged on both sides of the flotation tank 61. While one set follows the displacement of the displacement drive component, the other set also follows synchronously. The trapezoidal chute 611 included in the reset guiding component is arranged on the upper part of the inner side wall of the flotation tank 61. At the same time, the limit clamping column 612 included in the reset guiding component slides inside the trapezoidal chute 611. When the extension arm 613 of the reset guiding component is displaced by the traction of the displacement drive component, the extension arm 613 drives the limit clamping column 612 and the suspension arm 615 to displace. The limit clamping column 612 then displaces along the internal track of the trapezoidal chute 611. The suspension arms 615 included in the two sets of opposite reset guiding components drive the grille push plate 616 and the shift lever 617 installed between them to perform a linear position. When the limit clamping column 612 displaces along the lower track of the trapezoidal chute 611, the limit clamping column 612 will drive the suspension arm 615 to descend along the straight row limit groove 614 provided on the extension arm 613, causing the grille push plate 616 to sink into the flotation tank 61, and the shift lever 617 descends to the storage water level position of the flotation tank 61 to displace, stirring and evenly spreading the chemical raw materials floating on the storage water surface of the flotation tank 61.High-density impurities in the internal mixture of chemical raw materials begin to sink to the lower part inside the flotation tank 61 while being agitated, and the chemical raw materials remain on the water surface due to their own density. When the limit clamping column 612 moves to the end of the lower slide track of the trapezoidal chute 611, it starts to rise along the trapezoidal chute 611 and reaches the upper slide of the trapezoidal chute 611. The limit clamping column 612 then drives the suspension arm 615 to start rising along the clamping rail installed on the extension arm 613, and lifts the grid push plate 616 to the storage water surface of the flotation tank 61. At the same time, the displacement drive assembly drives the corresponding extension arm 613 to start reverse displacement, forcing the grid push plate 616 to push the flotation-treated chemical raw materials towards the material guiding inclined plate 62, and finally entering the receiving chute 5 installed on the side wall of the suspension frame 2 along the material guiding inclined plate 62, and being sent into the heating and loading mechanism 7 through the receiving chute 5 for melting and heating. While the flotation and pushing are in progress, the water level inside the flotation tank 61 will also drop accordingly, causing the buoyancy contact member 67 included in the liquid level control assembly to descend and separate from the induction gasket 68. Then the induction gasket 68 continues to replenish water until the water level inside the flotation tank 61 pushes the buoyancy contact member 67 to float up again and contact the induction gasket 68, thus achieving the automatic water replenishment ability of the flotation equipment. The heat insulation tank 71 included in the heating and loading mechanism 7 is fixed inside the suspension frame 2 and its lower part extends into the hopper-shaped box 101. After the flotation-treated chemical raw materials enter the heat insulation tank 71, the output motor 1 installed on the top of the operation frame 1 is started synchronously. The torque generated by the output motor 1 is driven to the mixing and traction mechanism 8 through the two-way belt guiding member 4. After the central linkage shaft 81 included in the mixing and traction mechanism 8 receives the torque conducted by the two-way belt guiding member 4, it synchronously drives the mixing blades 82 distributed on the side walls. The high-speed rotating mixing blades 82 generate a mixing and stirring force inside the heat insulation tank 71, causing the flotation-treated chemical raw materials inside the heat insulation tank 71 to be mixed and stirred. While the central linkage shaft 81 rotates, it will drive the coaxial transmission assembly included in the mixing and traction mechanism 8 to start operating. The component box 85 included in the coaxial transmission assembly is fixed on the side wall of the heat insulation tank 71. A set of central driving gears 88 is installed in the center of the component box 85 and rotates synchronously with the central linkage shaft 81. At the same time, intermediate transmission gears 89 are arranged around the central driving gear 88. The inner tooth key ring 86 is embedded in the side wall of the component box 85 and surrounds the intermediate transmission gears 89. When the intermediate transmission gears 89 are driven to rotate by the central driving gear 88, the inner tooth key ring 86 is driven to rotate by the intermediate transmission gears 89. Through the guiding transmission of the intermediate transmission gears 89, the rotational speed of the inner tooth key ring 86 is reduced relative to the inner tooth key ring 86. The inner tooth key ring 86 then drives the fixed ring frame 83 and the suspension spiral blades 84 located inside the heat insulation tank 71 to rotate through the T-shaped turntable 87. The suspension spiral blades 84 surround the mixing blades 82, and the chemical raw materials are then melted in close contact by the high temperature generated by the heating element 73 installed.After the molten chemical raw materials continue to enter the tablet pressing and granulating mechanism 9 along the discharge guiding pipe 72, while the suspended spiral blade 84 rotates at a high speed, the suspended spiral blade 84 also rotates slowly along the inner wall of the heat insulation tank 71, and generates a conveying thrust, pushing the molten and mixed chemical raw materials along the inner side wall of the heat insulation tank 71 towards the discharge guiding pipe 72 installed at the bottom wall of the heat insulation tank 71. While melting and mixing, the output of the molten chemical raw materials is synchronized. When the chemical raw materials reach the position of the fixed ring frame 83, the paddle 810 rotating slowly with the fixed ring frame 83 continuously pushes the chemical raw materials into the discharge guiding pipe 72. After the molten chemical raw materials enter the feeding pipe 94 included in the tablet pressing and granulating mechanism 9, they enter the inner pipe 92 along the feeding pipe 94. The inner pipe 92 is arranged inside the outer pipe 91, and at the same time, an overhead partition is arranged between the two, so that a channel structure that can communicate is formed between the two. The low-temperature air is injected into the channel structure by the later added air blowing mechanism, so that the side wall of the inner pipe 92 can be continuously cooled. After the chemical raw materials enter the inner pipe 92, the rotational torque generated by the output motor 1 is transmitted to the feeding linkage shaft 93 located inside the inner pipe 92 through the bottom output wheel of the bidirectional belt guiding member 4, so that the feeding linkage shaft 93 drives the spiral pusher 97 installed on the outside to start rotating and generate a thrust synchronously, pushing the molten chemical raw materials inside the inner pipe 92 towards the row of discharge holes 96 installed at the end of the inner pipe 92, and discharging along the row of discharge holes 96, and at the same time forming multiple strip-shaped raw materials, contacting the lead-out roller 98 installed in the front fixed frame 95. At the same time, according to the required thickness of the particles, the hydraulic output member 911 installed on the front fixed frame 95 is enabled to generate a traction force, driving the pressing moving roller 910 slidably installed on the front fixed frame 95 to move away from or close to the pressing fixed roller 99, so as to automatically control the gap between the two. After the strip-shaped raw materials reach the gap between the pressing moving roller 910 and the pressing fixed roller 99 along the lead-out roller 98, they are extruded into a thin sheet with a certain thickness, and at the same time contact the continuously rotating annular frame 912 on the front fixed frame 95. The cutting knives 913 installed on the periphery of the annular frame 912 continuously and evenly perform a granulation operation on the thin sheet raw materials to form the granular finished products of the chemical agent.
