Description

Technical Field

[0001] The present invention relates to the technical field of wet granulation, and more particularly to a continuous wet granulation device. Background Art

[0002] A wet granulator is a device used to convert powder into granules. It is mainly used in the pharmaceutical, food, feed, and ceramic industries. The main and auxiliary materials to be granulated are added to the blender in the appropriate proportions and formulas. The powder material and binder are fully mixed at high speed by the bottom mixing paddle in a cylindrical container to form a wet soft material. The material is then cut into uniform wet granules by the high-speed crushing paddle on the side, thus achieving the purpose of granulation.

[0003] The wet granulation device of the existing technology basically realizes the extrusion function through a twin-screw. After working for a long time, a large amount of carbide will adhere to the surface of the twin-screw. If it is not cleaned in time, it will not only cause impurities in subsequent products, affecting production quality, but also accelerate screw wear and reduce the service life of the screw. At present, when cleaning the twin-screw, most of the workers use a crowbar to dismantle the twin-screw outwards little by little, and then use a handheld grinding wheel to deeply clean its surface. Not only is the operation cumbersome, but also due to the heavy twin-screw, the workers are also at risk when cleaning. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When cleaning is required, the cooperation of various components can drive the linkage plate and the two extrusion screws to move horizontally. When the two extrusion screws move horizontally, they will rotate, which is convenient for the grinding wheel to grind and clean their surfaces. Moreover, since the extrusion screws rotate themselves during the horizontal movement, the grinding wheel can always fit with them, which greatly improves the cleaning effect. This not only saves a lot of manpower and time, but also improves cleaning efficiency and reduces production downtime caused by cleaning work.

[0017] 2. By adjusting the coordination of the motor, the second electric telescopic rod and other components, the height, position and grinding direction of the grinding wheel can be precisely adjusted. After the grinding of one extrusion screw is completed, the state of the grinding wheel can be quickly adjusted, and the other extrusion screw can be cleaned during the reset process.

[0018] 3. Through the clamping action of the square clamping column and the square clamping hole, the rotating rod can drive the linkage shaft to rotate synchronously when it rotates, so that the extrusion screw can realize the self-rotation function during the horizontal movement, which is convenient for grinding it. When the extrusion screw is working normally, the square clamping column and the square clamping hole are disconnected, so that the linkage shaft will not drive the rotating rod to rotate synchronously when it rotates, thereby effectively avoiding the extrusion screw from getting stuck during work.

[0040] like Figure 3 and Figure 6As shown, the extrusion mechanism also includes a right connecting block 5 and a left connecting block 8. The left connecting block 8 is slidably arranged in the extruder body 1. A connecting groove adapted to the right connecting block 5 is provided on the right side of the extruder body 1. The two ends of the two extrusion screws 4 are rotatably connected to the right connecting block 5 and the left connecting block 8 respectively. Two rotating shafts 9 are rotatably installed on the right connecting block 5. Both ends of the two rotating shafts 9 extend out of the right connecting block 5. One end of the two rotating shafts 9 is fixedly connected to the two extrusion screws 4 respectively. The other ends of the two rotating shafts 9 are fixedly sleeved with a first synchronous pulley 10. The two first synchronous pulleys 10 are connected by a first synchronous belt 11. By arranging two rotating shafts 9 in the right connecting block 5 and connecting the two by two first synchronous pulleys 10 and the first synchronous belt 11, one of the rotating shafts 9 can drive the other rotating shaft 9 to move synchronously when rotating, thereby making the two extrusion screws 4 rotate synchronously in the same direction.

[0049] The working principle and use process of the present invention are as follows: when in use, raw materials are put into the feed barrel 2, and the driving member 3 drives the two extrusion screws 4 to rotate synchronously in the same direction, thereby completing the granulation process, and the finished product is discharged and collected through the discharge port.

[0050] After a long period of production work, a lot of carbide will remain on the outer walls of the two extrusion screws 4. When cleaning is needed, production is stopped, the connection between the two fixing bolts 25 and the two thread grooves 26 is released, and the moving motor 62 is started to drive the screw guide sleeve 27 to rotate, so that the moving screw 28 is moved horizontally away from the extruder body 1 through the action of the thread. When the moving screw 28 initially moves, it can drive the linkage plate 6 to move synchronously, thereby driving the rectangular plug-in block 12 to move synchronously away from the plug-in slot 13. When it moves to a suitable position, the two trapezoidal clamping blocks 14 can be driven to move synchronously in the opposite direction through the elastic action of the two clamping springs 16, and realize the clamping function with the two clamping slots 17. At this time, when the linkage plate 6 continues to move, it can drive the right connecting block 5 and the two extrusion screws 4 to move horizontally synchronously through the clamping action of the two trapezoidal clamping blocks 14 and the two clamping slots 17. At the same time, when the movable screw 28 drives the linkage plate 6 to move initially, it can drive the rotating rod 30 to move synchronously. When the rotating rod 30 moves, it can drive the square slide plate 46 and the connecting shaft 44 inside it to move synchronously. At this time, if the square clamping column 45 is aligned with the square clamping hole 63, when the connecting shaft 44 moves, it can drive the square clamping column 45 to move horizontally into the square clamping hole 63 to achieve a clamping connection. If the square clamping column 45 has not been aligned with the square clamping hole 63, the squeezing of the square clamping column 45 and the end of the linkage shaft 41 can drive the connecting shaft 44 and the square slide plate 46 to remain stationary, and compress the avoidance spring 47 to avoid damage to the equipment.

[0051] At the same time, the moving screw 28 can drive the linkage plate 6, the drive shaft 29, and the hollow block 33 to move synchronously when it moves. When the hollow block 33 moves, it drives the circular shaft 35 and the drive gear 36 to move synchronously, so that through the meshing action of the drive gear 36 and the spur rack 37, the circular shaft 35 rotates during the movement, thereby driving the drive shaft 29 to realize the rotation function under the meshing action of the active bevel gear 38 and the driven bevel gear 39. When the drive shaft 29 rotates, the meshing action of the two second synchronous pulleys 31 and the second synchronous belt 32 can drive the rotating rod 30 to realize synchronous rotation.

[0052] When the rotating rod 30 rotates, it can drive the square slide 46 inside it to rotate synchronously, and then drive the square clamping column 45 to rotate synchronously through the connecting action of the connecting shaft 44. If the square clamping column 45 is outside the square clamping hole 63, when it rotates to an appropriate position, it can be driven to move into the square clamping hole 63 through the elastic action of the avoidance spring 47 to complete the clamping connection with the square clamping hole 63, so that the rotating rod 30 can drive the linkage shaft 41 to rotate synchronously when it rotates. When the linkage shaft 41 rotates, through the meshing action of the linkage main gear 43 and the linkage sub-gear 42, it can drive one of the rotating shafts 9 to realize the rotation function, and under the meshing action of the two first synchronous pulleys 10 and the first synchronous belt 11, the two rotating shafts 9 and the two extrusion screws 4 can realize synchronous rotation during the horizontal movement.

[0053] When the two extrusion screws 4 are moved outside the extruder body 1, the moving motor 62 is turned off, so that the extrusion screw 4 remains stationary. At this time, the second electric telescopic rod 66 is started to drive the grinding box 55 and the grinding wheel 58 to move upward synchronously, so that the outer wall of the peripheral side of the grinding wheel 58 is in contact with the outer wall of the peripheral side of the extrusion screw 4. At this time, the moving motor 62 and the grinding motor 57 are started, so that the extrusion screw 4 rotates by itself during the horizontal movement, so that the grinding wheel 58 is always in contact with it, thereby deeply cleaning it through the grinding wheel 58, avoiding the need for staff to manually grind and clean it after disassembling the extrusion screw 4.

[0054] When the grinding of one extrusion screw 4 is completed, the height of the grinding wheel 58 is adjusted by the second electric telescopic rod 66, and the adjusting motor 53 is started to drive one of the adjusting screws 50 to rotate. Under the meshing action of the two third synchronous pulleys 51 and the third synchronous belt 52, the two rectangular sliders 54 and the adjusting plate 49 are driven to move horizontally synchronously. When the adjusting plate 49 moves horizontally, the meshing action of the flip gear 65 and the fixed rack 67 can drive the cylindrical and circular base plates 64 to rotate 540 degrees synchronously, thereby adjusting the height of the grinding wheel 58. The grinding direction is adjusted, and then the grinding wheel 58 is driven to rise by the second electric telescopic rod 66 until it fits into contact with the outer wall of the circumference of the other extrusion screw 4. When the mobile motor 62 drives the two extrusion screws 4 to reset, the grinding wheel 58 is used to clean the other extrusion screw 4. During the rotation of the grinding wheel 58, the U-shaped scraper 60 can self-clean the outer wall of the grinding wheel 58, thereby improving its continuous grinding effect. The cleaned foreign matter is collected by the collection drawer 61 for subsequent centralized processing.

[0055] During the reset process of the two extrusion screws 4, the right connecting block 5 moves synchronously. When the induction switch 22 installed on the outer wall of the right connecting block 5 contacts the side of the extruder body 1, it means that the cleaning work is completed. At this time, the grinding motor 57 stops working and resets by adjusting the motor 53 and the second electric telescopic rod 66. The mobile motor 62 stops working, causing the right connecting block 5 to stop moving. At the same time, the induction switch 22 transmits an electrical signal to the position of the two first electric telescopic rods 18, so that the two first electric telescopic rods 18 drive the two extrusion blocks 19 to move toward each other, thereby making the two ladders The rectangular block 14 releases the limit engagement with the two slots 17. After the limit engagement is released, the mobile motor 62 continues to work, driving the linkage plate 6 and the rectangular plug-in block 12 to move horizontally synchronously. During this process, the linkage plate 6 drives the connecting shaft 44 and the square clamping column 45 to move synchronously, releasing the engagement between the square clamping column 45 and the square clamping hole 63, thereby avoiding the jamming of the two extrusion screws 4 during normal operation. When the inner walls of the side plug-in grooves 13 of the rectangular plug-in block 12 fit together, the right connecting block 5 is driven by the extrusion action to continue moving until it is reset. Finally, the right connecting block 5 is fixed by two fixing bolts 25.
