Description

Technical Field

[0001] The invention relates to the technical field of roller granulators, and in particular to a detection system and a detection method for a dry roller granulator. Background Art

[0002] Roller granulator is a special equipment for making dry powder materials into granular products. Its working principle is as follows: dry powder materials are added from the top of the equipment, and enter the rollers after degassing and spiral pre-pressing. Under the great squeezing force of the rollers, the materials are plastically deformed and compressed into flakes. Subsequently, the flake materials are crushed, granulated, screened, etc., and finally granular products are obtained.

[0003] In the dry roller granulation process, the parallelism of the rollers determines the uniformity of the gap between the rollers, which in turn affects the force and forming effect of the material between the rollers. If the parallelism of the rollers is not up to standard, the material may be unevenly stressed between the rollers, resulting in uneven particle size and irregular shape, and may even cause material blockage, equipment failure and other problems. However, if the particle size of the material entering the granulator is large, the force on the rollers on both sides will increase when it passes through the middle of the rollers, and the friction will also increase, resulting in increased vibration of the machine equipment, which are all factors that affect the stability of the rollers.

[0004] Therefore, it is necessary to provide a detection system and a detection method for a dry roller granulator to solve the above-mentioned technical problems. Summary of the invention

[0029] S2, then, start the rotating motor 1 and the rotating motor 2 and control their output directions through the PLC controller, so that when the vibration simulation mechanism adjusts its output position, the friction adjustment mechanism located above the roller also synchronously adjusts the contact position and contact angle between the V-plate and the roller;

[0030] S3. Then, according to the test needs, the vibration simulation mechanism and the friction adjustment mechanism can be set to a certain state, or they can be adjusted in real time, so as to simulate the force and friction generated by materials of different volumes falling to the middle of the two rollers on the two rollers through the position of the V-shaped plate, and the vibration simulation mechanism can be used to coordinate with the adjustment of the V-shaped plate to synchronously simulate the vibration of the equipment of different amplitudes caused by the materials of different volumes being squeezed by the rollers;

DETAILED DESCRIPTION

[0046] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0047] like Figure 1 As shown, the present invention provides a technical solution: a detection system for a dry roller granulator, comprising a base 1, a bearing mechanism 3, a vibration simulation mechanism 4, a friction adjustment mechanism 5 and a detection component 7;

[0048] A vertical plate 12 is installed on the base 1 by bolts, and two parallel upright fixing frames 2 are also installed by bolts. The fixing frames 2 are in a "U" shape. The control terminal 11 is installed on the base 1 and is provided with a PLC controller. The bearing mechanism 3 is arranged between the side walls of the fixing frames 2 on both sides. A pair of rollers 32 are rotatably arranged between the side walls of the bearing mechanism 3. A friction adjustment mechanism 5 is arranged above the bearing mechanism 3, and a vibration simulation mechanism 4 is arranged below the bearing mechanism 3, so that the bearing mechanism 3 can elastically reciprocate in the vertical direction. A detection component 7 is arranged on one side of the outside of the bearing mechanism 3 for judging the parallelism between the pair of rollers 32.

[0049] like Figure 2-3 As shown, the bearing mechanism 3 includes a mounting frame 31, a pair of rollers 32 and a connecting member 33;

[0050] The mounting frame 31 is arranged in a "U"-shaped structure, and a guide rod 311 is installed on its top by a threaded connection. The guide rod 311 passes through the fixing frame 2 and is in sliding contact with it. A limit block connected as an integral unit is arranged at the top of the guide rod 311, and a spring 1 is sleeved on the outer wall of the guide rod 311. The bottom end of the spring 1 is fixed to the top surface of the mounting frame 31, and the other end is fixedly connected to the bottom surface of the fixing frame 2.

[0051] A bottom groove is provided on the bottom wall of the mounting frame 31, and guide holes 312 are respectively provided on both sides of the bottom groove on the mounting frame 31, and the guide holes 312 are arranged along the length direction of the mounting frame 31. A "T"-shaped connecting member 33 is slidably provided between the inner walls of the bottom groove, and the top surface of the connecting member 33 is in sliding contact with the top wall of the bottom groove. The connecting member 33 is always moved and adjusted in a vertical state, and a sliding bolt connected and fixed to it is penetrated inside one end of the connecting member 33, and the sliding bolt slides between the guide holes 312 on both sides, and a connecting shaft 331 connected and fixed to it is penetrated inside the other end of the connecting member 33.

[0052] A pair of rollers 32 are rotatably arranged between the side walls of the mounting frame 31, and are rotatably arranged in opposite directions. An end shaft 321 connected to the rollers 32 is arranged at both ends. The end shaft 321 passes through the inner walls of the side walls of the mounting frame 31 and is rotatably arranged therebetween via bearings.

[0053] It should be further explained that when the mounting frame 31 is subjected to up and down vibration, the mounting frame 31 moves vertically along the side wall of the fixing frame 2, exerts a force on the spring 1 and generates extrusion when moving upward, and exerts a reaction force on the spring 1 when moving downward.

[0054] like Figure 2 and Figure 4 As shown, the detection assembly 7 is arranged between the two end shafts 321 on one side, and the detection assembly 7 includes an external shaft 71, a shaft cylinder 72 and a connecting ring 73;

[0055] The circumscribed shaft 71 is installed between the inner walls of the end shaft 321 by means of a key connection. Two connecting rings 73 are provided, and the two connecting rings 73 are respectively arranged at fixed positions on the two circumscribed shafts 71. Limiting rings are arranged on both sides of the installation position of the connecting ring 73. The limiting rings are fixed to the circumscribed shaft 71 by screws. The connecting ring 73 is in rotational contact with the circumscribed shaft 71. A piston shaft 2 731 is installed on the connecting ring 73 by means of a threaded connection. A key strip is installed on the outer surface of the end of the piston shaft 2 731 by means of screws. A shaft cylinder 72 is also provided between the piston shafts 2 731 on both sides. A key groove 721 is opened on the inner wall of the shaft cylinder 72. The key strip slides between the inner walls of the key groove 721. A spring 2 is connected between the end walls of the piston shafts 2 731 on both sides. The spring 2 is located in the shaft cylinder 72. An inclination sensor 722 is also embedded in the shaft cylinder 72. The inclination sensor 722 is connected to the PLC controller by an electrical signal.

[0056] It should be further explained that, during the reciprocating motion of the pair of rollers 32 with the mounting frame 31, if there is no offset between the pair of rollers 32, the two circumscribed shafts 71 are in a parallel state, and the distance between the two connecting rings 73 remains unchanged, and the value of the inclination sensor 722 is also always not 0. However, when an offset occurs between the pair of rollers 32, the distance between the two connecting rings 73 changes, and the spring 2 will produce a stretching feeling due to the change in distance, and the inclination sensor 722 will also change its angle, so as to judge the parallelism of the pair of rollers 32 under the test conditions.

[0057] like Figure 5-6 As shown, the vibration simulation mechanism 4 includes a key shaft 42, a screw rod 43, a transmission seat 44 and a movable seat 46;

[0058] A turning handle 41 is rotatably provided on one side wall of one of the fixing frames 2, a convex plate fixed thereto is connected to the side wall of the turning handle 41, a rotating motor 1 is mounted on the convex plate through a fixing frame, an output shaft of the rotating motor 1 passes through the inner wall of one end of the turning handle 41 and is connected to a screw 1 43, an arc-shaped through hole 1 is opened on the side wall of the fixing frame 2 contacting with the turning handle 41, the output shaft of the rotating motor 1 passes through the through hole 1 and slides between the inner walls of the through hole 1.

[0059] A synchronous shaft 1 is connected between the inner walls at the other end of the turning handle 41 and rotates synchronously therewith. The synchronous shaft 1 passes through the adjacent fixing frame 2 and is rotatably arranged between the inner walls of the fixing frame 2. The other end of the synchronous shaft 1 is connected and fixed to the key shaft 42. The other end of the key shaft 42 is rotatably arranged on the side wall of the fixing frame 2 through an axis connection.

[0060] A protrusion 441 is installed on the top surface of the transmission seat 44 by means of screws, the key shaft 42 penetrates the transmission seat 44 and is slidably arranged therewith, the screw rod 43 penetrates the protrusion 441 and is threadedly transmission-coordinated therewith, two parallel fixed arms 442 are installed by means of screws on one side wall of the transmission seat 44, the fixed arms 442 are plate-like structures, the movable seat 46 is an "I"-shaped structure and slides between the fixed arms 442 on both sides, two relatively arranged shaft seats 462 are installed on the top wall of the movable seat 46 by means of screws, the connecting shaft 331 penetrates between the two shaft seats 462 and is in rotational contact with them.

[0061] A through hole 2 is provided in the middle of the movable seat 46, and a movable ball 461 is movably provided in the middle of the through hole 2. A synchronization rod 451 passes through the inner walls of the movable ball 461. A connecting plate 22 is installed between the fixing frames 2 on both sides by screws. There are two connecting plates. A motor plate is installed in the middle of the bottom wall of one of the connecting plates by screws, and a rotating motor 2 is installed on the motor plate by bolts. Rotating arms 45 are rotatably provided on the opposite side walls of the connecting plates on both sides, and one of the rotating arms 45 is installed on the output shaft of the rotating motor 2. A synchronous wheel 1 47 is connected to one side of the other rotating arm 45 by a synchronous shaft 2. The rotating arm 45 and the synchronous wheel 1 47 are located on both sides of one of the connecting plates. The synchronous shaft 2 passes through the connecting plate and rotates in contact with it. The two ends of the synchronization rod 451 are respectively inserted between the inner walls of the ends of the rotating arms 45 on both sides.

[0062] It should be further explained that the rotating motor 1 and the rotating motor 2 are started synchronously through the PLC controller, the rotating motor 1 drives the screw rod 1 43 to rotate and adjust, and utilizes the cooperation between the key shaft 42 and the transmission seat 44, and under the drive of the screw rod 1 43, it slides and adjusts along the length direction of the key shaft 42, the rotating motor 2 drives the rotating arm 45 to rotate and adjust, and the rotating arms 45 on both sides synchronously rotate in circles in opposite directions, thereby driving the synchronization rod 451 to rotate back and forth. When the synchronization rod 451 moves with the rotating arm 45, the transmission seat 44 drives the fixed arm 442 to slide and adjust along the length direction of the key shaft 42. At the same time, the movable seat 46 slides back and forth between the two fixed arms 442, so that the fixed arm 442 drives the transmission seat 44 to swing back and forth. When swinging, the screw rod 1 43 and the key shaft 42 swing back and forth synchronously with the rotating handle 41, so as to cooperate with the movement of the transmission seat 44 and the movable seat 46.

[0063] When the movable seat 46 moves with the fixed arm 442 to the side close to the position of the rotating motor 2, the swing amplitude of the transmission seat 44 and the movable seat 46 is the largest. When the movable seat 46 moves with the fixed arm 442 to the side close to the position of the synchronous wheel 1 47, the swing amplitude of the transmission seat 44 and the movable seat 46 is the smallest.

[0064] like Figure 5 and Figure 7-8As shown, the friction adjustment mechanism 5 includes a V-shaped plate 51, an adjustment seat 52, a second guide rod 53 and a second screw rod 54;

[0065] A connecting plate 21 is installed between the side walls of the fixing frames 2 on both sides by bolts. The connecting plate 21 is a "convex" structure and is provided with two. A screw rod 2 54 is rotatably provided between the connecting plates 21 on both sides. A guide rod 2 53 is fixed between the connecting plates 21 on both sides above the screw rod 54 by screws. Symmetrical opposite threads are provided on the screw rod 54. Two relatively movable adjustment seats 52 are symmetrically provided on the screw rod 54. The screw rod 2 54 and the adjustment seat 52 are matched by threaded transmission, and the guide rod 2 53 passes through the adjustment seat 52 and is slidably connected thereto.

[0066] One end of the screw rod 2 54 is also connected to a synchronous wheel 2 55 which rotates synchronously therewith via a synchronous shaft 3. The synchronous wheel 2 55 is located on one side of one of the connecting plates 1 21 , and a transmission belt is connected between the synchronous wheel 2 55 and the synchronous wheel 1 47 .

[0067] Two protrusions connected to the adjustment seat 52 are welded on both side walls, and the V-shaped plate 51 can be folded and adjusted. Connecting pieces 511 are installed on both side walls of the V-shaped plate 51 by screws. A connecting block is rotatably provided between the two protrusions on the adjustment seat 52 by an axis, and the connecting piece 511 is fixed to the connecting block by screws.

[0068] There are a number of hemispherical protrusions distributed on both side walls of the V-shaped plate 51 .

[0069] It should be further explained that the screw rod 2 54 is driven to rotate by the transmission cooperation of the synchronous wheel 1 47 and the synchronous wheel 2 55, so that the relative movement of the two adjustment seats 52 is controlled under the action of the screw transmission. During the movement, the connecting pieces 511 on both sides synchronously drive the V-shaped plate 51 to open or close. When the V-shaped plate 51 is opened or closed, it will cooperate to adjust its height position up and down. When the angle of the V-shaped plate 51 becomes larger, the V-shaped plate 51 will increase the force applied to the rollers 32 on both sides, and at the same time increase the friction between the protrusion three and the rollers 32, thereby simulating the effect of a large volume of material falling on the rollers 32 on both sides. When the angle of the V-shaped plate 51 becomes smaller, the friction between the protrusion three and the rollers 32 is weakened, and the V-shaped plate 51 will move slightly downward along the middle position of the rollers 32, and reduce the force on the rollers 32 on both sides.

[0070] When the movable seat 46 moves toward the side where the rotating motor 2 is located, the rotating motor 1 and the rotating motor 2 are both driven in the clockwise direction, the rotating arm 45 close to the side where the rotating motor 2 is located rotates clockwise, and the rotating arm 45 on the other side rotates counterclockwise, so that the screw 2 54 rotates counterclockwise synchronously with the transmission of the synchronous wheel 2 55 (that is, the rotation directions of the screw 1 43 and the screw 2 54 are opposite at this time), so that the adjustment seats 52 on both sides move away from each other at this time, so that the V-plate is in an open state, and the movement amplitude of the movable seat 46 is the largest at this time, so that the amplitude of the roller 32 on the mounting frame 31 caused by the connecting member 33 is also the largest, otherwise the V-plate is in a closed state, and the amplitude of the roller 32 on the mounting frame 31 is weakened.

[0071] like Fig. 9 As shown, a transmission assembly 6 is also provided between the vertical plate 12 and one end wall of the roller pair 32, and the transmission assembly 6 includes a gear 61, a universal coupling 62, a sleeve 63 and a piston shaft 64;

[0072] Two gears 61 that mesh with each other are rotatably connected by an axis, and one side of one of the gears 61 is installed with a rotating motor 3 connected to it and driven by it on the side wall on the other side of the vertical plate 12 by bolts, and a universal coupling 62 is installed on the end shaft 321 on the same side end wall of the two pairs of rollers 32 by screws, and a piston shaft 1 64 is installed on the other end of the universal coupling 62 by screws, and a universal coupling 62 is also installed in the middle of the surface of the two gears 61 facing the pair of rollers 32 by screws, and a sleeve 63 is installed on the other end of the universal coupling 62 by screws, and one end of the piston shaft 1 64 slides between the inner walls of the sleeve 63 in a key connection manner, and this end of the piston shaft 1 64 is always located in the sleeve 63.

[0073] It should be further explained that, by starting the rotating motor three, it drives one of the gears 61 to rotate, thereby driving the other gear 61 to rotate, and making the two gears rotate in opposite directions, thereby driving the two pairs of rollers 32 to rotate relative to each other. Due to the provision of the universal joint 62, the bushing 63 and the piston shaft 1 64, even if the mounting frame 31 drives the pair of rollers 32 to vibrate up and down for adjustment, or the vibration causes the pair of rollers 32 to have displacement deviation and other problems, through the coordinated adjustment of the piston shaft 1 64 and the bushing 63, the two gears 61 can still drive the pair of rollers 32 to rotate and adjust.

[0074] Working principle:

[0075] First, install the two pairs of rollers 32 on the mounting frame 31, and connect and fix the universal coupling 62 on the transmission assembly 6 close to the pair of rollers 32 with the end shaft 321 on the pair of rollers 32, and start the rotating motor 3 so that the two gears 61 mesh with each other and rotate, and drive the two pairs of rollers 32 to rotate relatively at the same time through the universal coupling 62;

[0076] Next, the rotating motor 1 and the rotating motor 2 are started, and their output directions are controlled by the PLC controller. The rotating motor 1 drives the screw 1 43 to rotate, and the rotating motor 2 drives the rotating arm 45 connected thereto to rotate, while the rotating arm 45 on the other side rotates in the opposite direction to the rotating arm 45, so that under the transmission action of the synchronous wheel 1 47 and the synchronous wheel 2 55, the screw 2 54 is driven to rotate synchronously in the opposite direction with the rotating arm 45 on the other side, so that the transmission seat 44 adjusts its position along the direction of the screw 1 43 and the key shaft 42, and the two adjustment seats 52 also move and adjust along the direction of the screw 2 54 and the guide rod 2 53, and then while realizing the up and down vibration simulation of the mounting frame 31, the angle of the V-plate is adjusted synchronously to meet and realize a series of external influencing factors generated when materials of different sizes fall into the two pairs of rollers 32 and are squeezed;

[0077] According to the test needs, the vibration simulation mechanism 4 and the friction adjustment mechanism 5 can be set in a certain state, or they can be adjusted in real time, so as to simulate the force and friction generated by materials of different volumes falling to the middle of the two rollers 32 through the position of the V-shaped plate, and the vibration simulation mechanism 4 cooperates with the adjustment of the V-shaped plate to synchronously simulate the equipment vibration feeling of different amplitudes caused by materials of different volumes being squeezed by the rollers 32;

[0078] Then, the stability of the roller 32 during the operation of the roller granulator is determined by detecting the change in the length of the component 7 and the change in the angle of the inclination sensor 722 .
