Description

Technical Field

[0002] Wet granulator is a kind of equipment used to make powder into granules. It is mainly used in pharmaceutical, food, feed and ceramic industries. The main materials and auxiliary materials to be granulated are added into the agitator according to the appropriate proportion and formula. The powder material and the binder are fully mixed at high speed by the bottom mixing paddle in the cylindrical container to form a wet soft material, which is then cut into uniform wet granules by the side high-speed crushing paddle, thus achieving the purpose of granulation.

[0003] The wet granulation device of the prior art 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 the subsequent products, affecting the production quality, but also accelerate the wear of the screw and reduce the service life of the screw. At present, when cleaning the twin screw, most of the workers use a crowbar to disassemble the twin screw outwards little by little, and then use a handheld grinding wheel to deeply clean its surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When cleaning is required, the cooperation of various components can drive the linkage plate and the two extrusion screws to move horizontally, and the two extrusion screws will rotate when moving horizontally, which is convenient for the grinding wheel to grind and clean their surfaces. Since the extrusion screws rotate by themselves during the horizontal movement, the grinding wheel can always fit with them, which greatly improves the cleaning effect.

[0016] 2.

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.

For example, the driving member 3 is an extrusion motor, and a spline sleeve is provided on the output shaft of the extrusion motor. The extrusion screw 4 facing the spline sleeve is fixedly connected with a spline shaft, and the spline shaft can be slidably inserted into the spline sleeve, so that the extrusion motor can drive the extrusion screw 4 to rotate.

[0024] like Figure 3 and Figure 6 As 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 opened 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, so that the two extrusion screws 4 can rotate synchronously in the same direction.

[0025] like Figure 4 and Figure 5As shown, the linkage mechanism also includes a rectangular plug-in block 12, a plug-in slot 13 is provided at one end of the right connecting block 5, and a clamping slot 17 is provided on the opposite inner walls of the plug-in slot 13. One side of the rectangular plug-in block 12 is fixedly installed on the side of the linkage plate 6, and the other side of the rectangular plug-in block 12 is slidably installed in the plug-in slot 13. Slide grooves are provided on both sides of the rectangular plug-in block 12, and guide shafts 15 are fixedly installed on the inner walls of the sides of the two slide grooves close to each other.

Extrusion blocks 19 are provided at the output ends of the two first electric telescopic rods 18. The sides of the two extrusion blocks 19 close to each other are both inclined. With this arrangement, the connection between several components can be achieved through the rectangular plug-in block 12 during the sliding process, so that the extrusion screw 4 can rotate during horizontal movement, and the card connection between the two trapezoidal card blocks 14 and the two card grooves 17 can make the extrusion screw 4 continue to rotate when it is reset, so as to facilitate the grinding of its surface.

[0026] like Figure 6 and Figure 8 As shown, the linkage mechanism also includes an induction switch 22. Specifically, the induction switch 22 can be controlled by a PLC controller and electrically connected to other components. Two side plates 20 are fixedly installed on the outer wall of the circumference of the right connecting block 5. The sides of the two side plates 20 are provided with round holes, and fixing bolts 25 are movably provided in the two round holes. Two thread grooves 26 are provided on the side of the extruder body 1, and the two fixing bolts 25 are respectively adapted to the two thread grooves 26.

The induction switch 22 is fixedly installed on one end of the extrusion shaft 21, and the extrusion shaft 2 1 is fixedly provided with a limited circular plate at the other end, a compression spring 24 is sleeved on the peripheral outer wall of the extrusion shaft 21, and a avoidance groove 23 adapted to the induction switch 22 is opened on the side of the side plate 20. Such an arrangement enables the extrusion screw 4 to maintain the self-rotation function in the initial stage of resetting. When the grinding operation is completed, the induction switch 22 is in contact with the extruder body 1, thereby transmitting an electrical signal to the PLC controller, thereby driving the two first electric telescopic rods 18 to drive the extrusion block 19 to move, releasing the clamping connection between the trapezoidal clamping block 14 and the clamping groove 17, so that the extrusion screw 4 will no longer rotate during horizontal movement.

[0027] like Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11As shown, the linkage mechanism also includes a rotating rod 30 and a linkage shaft 41.

In this way, the square clamping column 45 and the square clamping hole 63 can be clamped together, so that when the rotating rod 30 rotates, it can drive the linkage shaft 41 to rotate synchronously, so that the extrusion screw 4 can realize the self-rotation function during the horizontal movement, which is convenient for grinding it. When the extrusion screw 4 is working normally, since the square clamping column 45 and the square clamping hole 63 are disconnected, the linkage shaft 41 can not drive the rotating rod 30 to rotate synchronously when it rotates.

The driving shaft 29 and the peripheral outer wall of the rotating rod 30 are fixedly sleeved with a second synchronous pulley 31, and the two second synchronous pulleys 31 are connected by a second synchronous belt 32. Such an arrangement can drive the linkage plate 6 to realize the horizontal movement function through the threaded action of the screw guide sleeve 27 and the movable screw 28, thereby driving the right connecting block 5 and the two extrusion screws 4 to move horizontally synchronously.

[0029] like Fig.13 As shown, a rotating hole is provided on the bottom inner wall of the hollow block 33, and a circular shaft 35 is rotatably installed in the rotating hole.

The peripheral outer walls of the two adjusting screws 50 are threadedly mounted with rectangular sliders 54, and the two rectangular sliders 54 are fixedly connected to the adjusting plate 49. In this way, the two rectangular sliders 54 and the adjusting plate 49 can be driven to move synchronously through the thread action of the adjusting screw 50 and the meshing action of the two third synchronous pulleys 51 and the third synchronous belt 52, thereby adjusting the position of the grinding wheel 58.

[0034] After a long period of production work, a lot of carbides 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 in the direction 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 in the direction 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 synchronously horizontally 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.

[0035] At the same time, the movable screw 28 can drive the linkage plate 6, the drive shaft 29, and the hollow block 33 to move synchronously when moving. 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, so that under the meshing action of the active bevel gear 38 and the driven bevel gear 39, the drive shaft 29 is driven to realize the rotation function. When the drive shaft 29 rotates, through the meshing action of the two second synchronous pulleys 31 and the second synchronous belt 32, it can drive the rotating rod 30 to realize synchronous rotation.

[0036] When the rotating rod 30 rotates, it can drive the square slide plate 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 a suitable 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.

[0037] 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 peripheral outer wall of the grinding wheel 58 is in contact with the peripheral outer wall 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 itself during the horizontal movement, so that the grinding wheel 58 is always in contact with it, so that it is deeply cleaned by the grinding wheel 58, avoiding the need for staff to manually grind and clean the extrusion screw 4 after disassembling it.

[0038] 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 cylindrical and circular bottom plates 64 can be driven to rotate 540 degrees synchronously through the meshing action of the flip gear 65 and the fixed rack 67, 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 against 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.

[0039] During the resetting 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 cooperation of the motor 53 and the second electric telescopic rod 66. The mobile motor 62 stops working, so that the right connecting block 5 stops 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 connection with the two slots 17. After the limit 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 clamping connection between the square clamping column 45 and the square clamping hole 63, avoiding the jamming phenomenon when the two extrusion screws 4 are working normally. When the inner walls of the side plug-in grooves 13 of the rectangular plug-in block 12 are in contact with each other, the right connecting block 5 is driven to continue moving through the extrusion effect until it is reset, and finally the right connecting block 5 is fixed by two fixing bolts 25.
