Abstract
Description
Technical Field
[0001] The present application relates to the technical field of granulator adjustment, and in particular to a forming roller adjustment method and an adjustable granulator. Background Art
[0002] The granulator includes two forming rollers, and the outer peripheral walls of the two forming rollers are provided with forming grooves. By placing the material between the two forming rollers, the material enters the forming grooves. When the two forming rollers squeeze each other, the forming grooves of the two forming rollers face each other, and the groove walls of the forming grooves squeeze the material entering the forming grooves into granules, and the material eventually falls from under the forming rollers.
[0003] In order to maintain the synchronization of the rotation of the forming rollers, one of the two forming rollers is usually a driving roller and the other is a driven roller. When producing material particles of different sizes or materials, personnel need to adjust the distance between the two forming rollers to achieve the purpose of producing material particles of different lengths and sizes. However, the current adjustment of the distance between the forming rollers requires personnel to manually disassemble the original forming rollers and replace them with forming rollers of different diameters, which is relatively inconvenient. Summary of the Invention
[0004] In order to facilitate the adjustment of the distance between two forming rollers, the present application provides a forming roller adjustment method and an adjustable granulator.
[0005] In a first aspect, the present application provides a method for adjusting a forming roller, which adopts the following technical solution:
[0006] A method for adjusting a forming roller comprises the following steps:
[0007] Obtaining personnel input of forming roller adjustment information;
[0008] According to the forming roller adjustment information, the driven forming roller is driven to rotate around a reference line parallel to its own axis so that the distance between the two forming rollers corresponds to the forming roller adjustment information;
[0009] Obtaining detection information, and judging whether the forming grooves on the two forming rollers are aligned according to the detection information;
[0010] If not, the driven forming roller is controlled to delay or rotate in advance so that the forming grooves on the two forming rollers can face each other.
[0011] By adopting the above-mentioned technical solution, the present application can automatically adjust the distance between the two forming rollers to the width corresponding to the forming roller adjustment information after receiving the forming roller adjustment information, and determine whether the distance between the two forming rollers has been adjusted based on the acquired distance information. After the distance adjustment is completed, the problem of the forming groove not being aligned is handled, and the driven forming roller is delayed or rotated in advance so that the first forming groove and the second forming groove can be aligned, thereby automatically completing the adjustment.
[0012] Preferably, obtaining detection information and judging whether the forming grooves on the two forming rollers are aligned according to the detection information further includes the following steps:
[0013] Acquiring first laser incident information and second laser incident information respectively transmitted by two laser receiving devices installed on the adjustable granulator, wherein the distance between the installation points of the two laser receiving devices and the plane where the axes of the two forming rollers are located remains constant during the adjustment process of the adjustable granulator, the laser emitting device adapted to the laser receiving device is fixedly connected to the forming roller and corresponds to the position of the forming groove, and the distance between the laser receiving device and the axis of the forming roller where its own laser emitting device is located remains constant;
[0014] It is determined whether a time difference between a time when the first laser incident information is acquired and a time when the second laser incident information is acquired is zero.
[0015] By adopting the above technical solution, it is more convenient to obtain the first laser incident information and the second laser incident information, and to understand whether the forming grooves on the two adjusted forming rollers are aligned through the first laser incident information and the second laser incident information.
[0016] Preferably, in controlling the power delay or advance rotation of the driven forming roller according to the lateral adjustment information, the following steps are also included:
[0017] According to the time difference, a preset time difference lateral adjustment table is traversed to obtain lateral adjustment information;
[0018] According to the transverse shift adjustment information, the power gear on the driven forming roller is moved along its radial direction by a corresponding distance so that the rotation of the driven forming roller is delayed or advanced.
[0019] By adopting the above technical solution, the meshing clearance between the gears is changed by moving the power gear along its radial direction by a corresponding distance, thereby achieving the purpose of delaying or advancing the rotation of the driven forming roller, which is quite clever.
[0020] Preferably, before obtaining the forming roller adjustment information input by the personnel, the following steps are also included:
[0021] Obtaining motor current information of the forming roller drive motor;
[0022] Determining whether the motor current information is greater than a first preset value;
[0023] If yes, increase the power of the forming roller drive motor to a preset power;
[0024] Obtaining the motor current information of the forming roller drive motor again, and determining whether the motor current information is greater than a second preset value;
[0025] If so, the system enters the adjustment mode to obtain the personnel input of the forming roller adjustment information.
[0026] By adopting the above technical solution, when the material is too hard and the gap between the two forming rollers is too small, resulting in excessive resistance and affecting the normal operation of the forming roller drive motor, it can be understood by detecting the current of the forming roller drive motor. If the current of the forming roller drive motor is too large, it means that the rotor is blocked, resulting in a decrease in the reverse voltage generated by cutting the magnetic flux lines, resulting in excessive current passing through the motor. By increasing the power of the forming roller drive motor to a preset power, the forming roller drive motor overcomes the resistance and restores the normal speed. If the motor current information is still abnormal after the forming roller drive motor reaches the preset power, it means that the forming roller drive motor cannot work normally under the gap, and the gap between the two forming rollers needs to be adjusted so that the forming roller drive motor can work normally.
[0027] In the second aspect, the present application also provides an adjustable granulator adopting the following technical solution:

The coupling is used to be driven by the gear drive mechanism to drive the second forming roller to rotate. The coupling is provided with a non-circular connecting hole, and the second forming roller is provided with a connecting shaft for being embedded in the non-circular connecting hole to drive the second forming roller to rotate.

After the second forming roller, that is, the driven forming roller, in order to enable the forming grooves on the first forming roller and the second forming roller to process the material normally, personnel can adjust the gear meshing degree between the coupling part and the gear drive mechanism by driving the electric control transverse movement mechanism, so that the rotation of the second forming roller relative to the first forming roller is delayed or advanced, so that after the second forming roller is offset due to the rotation of the adjustment part, the forming grooves on the first forming roller and the second forming roller can be aligned again, thereby completing the adjustment of the distance between the first forming roller and the second forming roller, without the need for personnel to disassemble and assemble equipment, which is more convenient.

Personnel can accurately understand the adjustment status of the first forming roller and the second forming roller through the intelligent processing equipment.

[0050] It should be noted that in order to more clearly demonstrate the working principle of the present application, the present application arranges the embodiments from the logic of the device side to the method side rather than the order of priority.
[0051] The specific implementation manner of the present application discloses an adjustable granulator in the embodiment.
[0052] Reference Figure 1 , an adjustable granulator includes a machine base 1, a first forming roller 2 rotatably connected to the machine base 1, an adjusting member 3 and a gear driving mechanism 4.
[0053] The bottom of the base 1 is against the ground to support the adjustable granulator of the present application. The gear drive mechanism 4 is disposed on the base 1. The gear drive mechanism 4 includes a drive motor 41 and a reduction gearbox 42. The input end of the reduction gearbox 42 is fixedly connected to the output shaft of the drive motor 41. The output shaft of the reduction gearbox 42 is coaxially fixed to the first forming roller 2 to drive the first forming roller 2 to rotate. The first forming roller 2 is an active forming roller. The surface of the first forming roller 2 is provided with a plurality of first forming grooves 21. The first forming grooves 21 are distributed in an array on the outer surface of the first forming roller 2.
[0054] Reference Figure 1 and Figure 2The adjusting member 3 is rotatably connected to the base 1. The adjusting member 3 is cylindrical and rotatably mounted on a second forming roller 31. This second forming roller 31 is a driven forming roller. The axis of the second forming roller 31 is parallel to the axis of the first forming roller 2 and the axis of rotation of the adjusting member 3. Second forming grooves 32 are evenly distributed on the surface of the second forming roller 31, corresponding to the first forming grooves 21. The base 1 is equipped with an electrically controlled adjusting mechanism 5 that drives the adjusting member 3 in rotation. This electrically controlled adjusting mechanism 5 includes a first adjusting gear 51 and an adjusting ring gear 52 meshing with the first adjusting gear 51. The first adjusting gear 51 is rotatably connected to the base 1. The adjusting ring gear 52 is coaxially fixed to the adjusting member 3 and has incomplete teeth. A stepper motor 53 is also fixedly mounted on the base 1. The output shaft of the stepper motor 53 is coaxially fixed to the first adjusting gear 51 to drive the first adjusting gear 51 in rotation. In other embodiments, the stepper motor 53 can also drive the first adjusting gear 51 through a reduction gear box.
[0055] The stepper motor 53 can be used to rotate the adjustment member 3 to change the position of the axis of the second forming roller 31, so that the axis of the second forming roller 31 moves away from or closer to the first forming roller 2, thereby adjusting the distance between the first forming roller 2 and the second forming roller 31. However, the change in the position of the second forming roller 31 may cause driving problems.
[0056] Reference Figure 1 and Figure 3 The present application has further improved this problem. A connecting shaft 33 is provided at the end of the second forming roller 31. The connecting shaft 33 is coaxially arranged with the second forming roller 31. The cross-sectional shape of the connecting shaft 33 is gear-shaped. In other embodiments, it can also be a non-circular shape such as a polygon. The base 1 is also provided with a coupling 6. The end of the coupling 6 facing the connecting shaft 33 is provided with a non-circular connecting hole 63 for the connecting shaft 33 to be inserted. The shape of the non-circular connecting hole 63 is similar to the cross-sectional shape of the connecting shaft 33, and the cross-sectional dimension of the non-circular connecting hole 63 is larger than the cross-sectional dimension of the connecting shaft 33. The outer surface of the coupling 6 is coaxially provided with a power gear 64 that meshes with the gear drive mechanism 4. The output shaft of the reduction gearbox 42 is fixed with a transmission gear 65. The power gear 64 meshes with the transmission gear 65, so that the reduction gearbox 42 can drive the first forming roller 2 and the second forming roller 31 to rotate at the same speed. There is an adjustable spacing 66 between the inner wall of the connecting hole and the connecting shaft 33. After the axis of the second forming roller 31 is adjusted, the adjustment distance 66 between the connecting shaft 33 of the second forming roller 31 and the inner wall of the non-circular connecting hole 63 is increased or decreased, so that the coupling 6 can still drive the second forming roller 31 to rotate.
[0057] However, since the relative position of the second forming roller 31 and the first forming roller 2 is offset after the second forming roller 31 rotates, after the first forming roller 2 and the second forming roller 31 rotate relative to each other at the same speed, the first forming groove 21 and the second forming groove 32 cannot be aligned due to the offset. Therefore, the coupling 6 of the present application includes a sliding portion 62 and a rotating portion 61. The sliding portion 62 adopts a bearing seat, and the rotating portion 61 is rotatably connected to the sliding portion 62. The non-circular connecting hole 63 and the power gear 64 are both located on the rotating portion 61. The sliding portion 62 is slidably connected to the machine base 1, and the sliding direction of the sliding portion 62 is horizontal and perpendicular to the axial direction of the second forming roller 31.
[0058] The base 1 is also provided with an electrically controlled transverse movement mechanism 9 for driving the radial movement of the coupling 6. The electrically controlled transverse movement mechanism 9 utilizes an electric screw. The axial direction of the output shaft of the electrically controlled transverse movement mechanism 9 is along the sliding direction of the sliding portion 62. The output shaft of the electrically controlled transverse movement mechanism 9 is threadedly connected to the sliding portion 62 to drive the sliding portion 62 to slide. The electrically controlled transverse movement mechanism 9 can change the distance between the power gear 64 and the transmission gear 65. When the distance between the power gear 64 and the transmission gear 65 increases, the gap between the meshing teeth of the power gear 64 and the transmission gear 65 increases, resulting in a rotational delay, thereby correcting the relative positional offset of the second forming roller 31 and the first forming roller 2, allowing the first forming groove 21 and the second forming groove 32 to function normally.
[0059] Reference Figure 1 and Figure 2 , in order to further improve the degree of automation of this application. This application is further improved: an intelligent processing device 7 is fixedly installed on the machine base 1, and the intelligent processing device 7 can be a PLC, a microcomputer or other intelligent device. A mounting assembly 8 is provided between the first forming roller 2 and the second forming roller 31, and the mounting assembly 8 includes a telescopic pipe 81 and two connecting rings 82. The two connecting rings 82 are fixedly sleeved on the first forming roller 2 and the second forming roller 31 respectively. A rotating ring 83 is coaxially provided on the two connecting rings 82, and a rotating ring groove 84 for the rotating ring 83 to be embedded is provided on the first forming roller 2 and the second forming roller 31, and the rotating ring groove 84 is adapted to the size of the rotating ring 83. The side wall of the rotating ring 83 is in contact with the groove wall of the rotating ring groove 84, so that the rotating ring 83 is limited by the rotating ring groove 84 and cannot move along its own axis.
[0060] Reference Figure 2 and Figure 4The telescopic tube 81 includes a first tube 811 and a second tube 812 sleeved onto the first tube 811. The end of the first tube 811 facing away from the second tube 812 is fixed to a rotating ring 83 on the first forming roller 2, and the end of the second tube 812 facing away from the first tube 811 is fixed to another rotating ring 83. The first tube 811 and the second tube 812 are slidably connected. The second tube 812 is fixed with a distance detection sensor 85 for detecting the distance between the second tube 812 and the first tube 811. The distance detection sensor 85 is a capacitive displacement sensor, and the detection end of the capacitive displacement sensor is fixed to the first tube 811. The capacitive displacement sensor is coupled to the intelligent processing device 7, which has a display screen.
[0061] After the second forming roller 31 is adjusted by the electric control adjustment mechanism 5 and the relative position of the second forming roller 31 and the first forming roller 2 is offset, the distance between the axis of the second forming roller 31 and the axis of the first forming roller 2 will increase or decrease, causing the telescopic tube 81 to be extended or shortened, so that the distance detection sensor 85 detects the distance information between the second tube 812 and the first tube 811 and transmits the distance information to the intelligent processing device 7. The intelligent processing device 7 converts the distance information into the spacing value between the first forming roller 2 and the second forming roller 31 through calculation. The calculation can use the initial distance information between the two rollers plus the changed distance information between the second tube 812 and the first tube 811, and display it on the display screen for personnel reference.
[0062] After the second forming roller 31 is adjusted by the electric control adjustment mechanism 5, the angle between the same second forming groove 32 thereon and the axis of the first forming roller 2 will also change, resulting in the second forming groove 32 being unable to face the corresponding first forming groove 21, thereby causing the produced pellets to have irregular shapes and poor quality.
[0063] Therefore, in order to ensure that the second forming roller 31 is adjusted by the electronically controlled adjustment mechanism 5 , the second forming groove 32 cannot still be directly opposite to the corresponding first forming groove 21 .
[0064] In this application, both connecting rings 82 are equipped with laser emitting devices 86. These devices are laser emitters. The line connecting the fixed connection between the first tube 811 and the rotating ring 83 and the locations of the laser emitters on the first forming roller 2 runs along the length of the first forming roller 2. The laser emitters are removably connected to the connecting ring 82 via bolts. The position of the laser emitting device 86 on the first forming roller 2 corresponds to the first forming groove 21, and the position of the laser emitting device 86 on the second forming roller 31 corresponds to the second forming groove 32. Each rotating ring 83 is equipped with a laser receiving device 87 compatible with the laser emitting device 86. When the first and second forming rollers 2 and 31 rotate, and the second forming groove 32 aligns with the corresponding first forming groove 21, the laser receiving devices 87 on both rotating rings 83 simultaneously receive the laser signals emitted by the laser emitting devices 86. Both the laser emitting devices 86 and the laser receiving devices 87 are coated with a corrosion-resistant layer. This layer can be a thick-build glass flake coating, specifically FE epoxy flake coating or H highly chlorinated polyethylene flake coating. The electric lead screw, the stepper motor 53 , the drive motor 41 and the laser receiving device 87 are all coupled to the intelligent processing device 7 , and the electric lead screw, the stepper motor 53 and the drive motor 41 are all controlled and operated by the intelligent processing device 7 .
[0065] In addition, a barrier cover 88 is fixedly mounted on the connecting ring 82. The barrier cover 88 is annular and has both axial ends that are sleeved onto the surface of the rotating ring 83 and in contact with the surface of the rotating ring 83, allowing it to rotate relative to the rotating ring 83. The two barrier covers 88 are respectively fixed to the first tube 811 and the second tube 812. The laser emitting end of the laser emitter and the receiving end of the laser receiving device 87 are both located within the barrier covers 88, shielding the laser emitter and the laser receiving device 87 from the outside world and preventing corrosive dust from falling on them. The barrier covers 88 can prevent dust in the air from falling on the laser emitting end of the laser emitter and the receiving end of the laser receiving device 87, which could affect the laser receiving device 87's reception of the laser and cause inaccurate detection. In addition, the surface of the barrier cover 88 is also coated with a corrosion-resistant layer.
[0066] The implementation principle of an adjustable granulator in an embodiment of the present application is: by setting an electric-controlled adjustment mechanism 5 and an electric-controlled transverse movement mechanism 9, personnel or intelligent processing equipment 7 drive the electric-controlled adjustment mechanism 5 to adjust the distance between the first forming roller 2 and the second forming roller 31, and adjust the movement of the connecting shaft 6 through the electric-controlled transverse movement mechanism 9, so that a transmission delay is generated between the power gear 64 and the transmission gear 65, so that after the distance adjustment is completed, the first forming groove 21 on the first forming roller 2 and the second forming groove 32 on the second forming roller 31 can be aligned when the first forming roller 2 and the second forming roller 31 rotate relative to each other, so that the pellets can be processed and formed normally.
[0067] The embodiment of the present application also discloses a method for adjusting a forming roller.
[0068] Reference Figure 5 , a method for adjusting a forming roller, comprising the following steps:
[0069] S0: obtaining motor current information of the forming roller drive motor, determining whether the motor current information is greater than a first preset value, and if so, increasing the power of the forming roller drive motor to a preset power, obtaining motor current information of the forming roller drive motor again, determining whether the motor current information is greater than a second preset value, and if so, entering an adjustment mode;
[0070] Specifically: It should be noted that this step is a pre-step before adjusting the forming rollers, and is mainly applicable after the material is replaced. Due to the material being too hard or the particles being too large, the gap between the two forming rollers is too small, which will cause the two forming rollers to completely crush the material into powder before the material can pass through the two forming rollers, resulting in increased resistance, making it impossible for the forming roller drive motor to rotate normally. The speed of the forming roller drive motor slows down, resulting in a decrease in its reverse potential, which in turn causes an increase in the current passing through the forming roller drive motor. At this time, the motor current information of the forming roller drive motor is obtained through the current sensor, and then the motor current information is compared with the first preset value to determine whether the motor current information is greater than the first preset value. The first preset value can be adjusted by personnel based on actual conditions. If the motor current is greater than the second preset value, it indicates that the motor current information is abnormal and the rotation of the forming roller drive motor is obstructed. In response to this situation, the first solution of this application is to appropriately increase the power of the forming roller drive motor without affecting the normal use of the forming roller drive motor so that it reaches the preset power. Specifically, this can be achieved by increasing the voltage at both ends of the forming roller drive motor through the voltage regulation circuit. If the motor current information detected by the current sensor again is greater than the second preset value after the forming roller drive motor reaches the preset power, the second preset value is the maximum current value of the forming roller drive motor when it is working normally at the preset power; if the motor current information is greater than the second preset value, it means that the resistance caused by the material passing through the gap is too large and cannot be solved by adjusting the forming roller drive motor. The intelligent processing device 7 enters the adjustment mode and is ready to receive the forming roller adjustment information input by the personnel. In addition, the personnel can also manually operate the intelligent processing device 7 to make the intelligent processing device 7 enter the adjustment mode to obtain the forming roller adjustment information input by the personnel.
[0071] S1: Acquiring the forming roller adjustment information input by the personnel and the distance information sent by the distance detection sensor 85;
[0072] Specifically: after the intelligent processing device 7 enters the adjustment mode, the personnel inputs the forming roller adjustment information into the intelligent processing device 7 through the touch screen of the intelligent processing device 7. The forming roller adjustment information can be the distance value between the second forming roller 31 and the first adjustment roller 2. At the same time, the intelligent processing device 7 obtains the distance information through the distance detection sensor 85. The distance information is actually the detection data of the distance detection sensor 85.
[0073] S2: driving the stepping motor 53 to rotate according to the forming roller adjustment information to adjust the position of the second forming roller 31 so that the distance information and the forming roller adjustment information meet the preset rules;
[0074] Specifically: the intelligent processing device 7 will traverse the preset motor rotation table according to the forming roller adjustment information to obtain the number of rotations of the stepper motor 53, wherein the motor rotation table includes a number of forming roller adjustment information and the corresponding number of rotations of the stepper motor 53. Then, the intelligent processing device 7 drives the stepper motor 53 to rotate the corresponding number of rotations according to the number of rotations of the stepper motor 53, so as to drive the adjustment member 3 to rotate the corresponding angle, thereby adjusting the position of the second forming roller 31, so that the distance between the first forming roller 2 and the second forming roller 31 increases or decreases. The preset rule is the calculation formula that needs to be substituted for the detection data of the distance detection sensor 85 to convert it into the distance value between the first forming roller 2 and the second forming roller 31. For example, when the sum of the distance information plus the preset specific value is equal to the forming roller adjustment information, it meets the preset rule. After the distance information and the forming roller adjustment information meet the preset rule, the intelligent processing device 7 stops driving the stepper motor 53 to rotate and locks the stepper motor 53.
[0075] S3: Acquire the first laser incident information and the second laser incident information received by the two laser receiving devices 87;
[0076] Specifically: wherein the first laser incident information and the second laser incident information are components of the detection information, and then the intelligent processing device 7 drives the drive motor 41 to rotate so that the first forming roller 2 and the second forming roller 31 rotate relative to each other, and then the intelligent processing device 7 obtains the first laser incident information sent by the laser emitting device 86 through the laser receiving device 87 on the first forming roller 2, and obtains the second laser incident information through the laser receiving device 87 on the second forming roller 31;
[0077] S4: Determine whether the time difference between the acquisition time of the first laser incident information and the acquisition time of the second laser incident information is zero;
[0078] Specifically: after obtaining the first laser incident information and the second laser incident information, the intelligent processing device 7 determines whether the time difference between the acquisition time of the first laser incident information and the acquisition time of the second laser incident information is zero;
[0079] It should be noted that since the position between the laser emitting device 86 and the first forming roller 2 or the second forming roller 31 is relatively unchanged, after the second forming roller 31 is adjusted, it is the relative position of the rotating ring 83 on the connecting ring 82 that changes. When the second forming roller 31 is not adjusted, because the length of the telescopic tube 81 is perpendicular to the axes of the first forming roller 2 and the second forming roller 31, when one row of the first forming grooves 21 is directly opposite the corresponding second forming grooves 32 to perform extrusion molding on the material, the first laser incident information and the second laser incident information are received simultaneously, and the time difference between the acquisition time of the first laser incident information and the acquisition time of the second laser incident information is zero. Therefore, the reception time of the first laser incident information and the second laser incident information can be used to determine whether the first forming groove 21 is directly opposite the corresponding second forming groove 32.
[0080] S5: If it is not zero, traverse the preset time difference lateral adjustment table according to the time difference to obtain lateral adjustment information;
[0081] Specifically: when the time difference is not zero, it means that the first forming groove 21 is no longer facing the corresponding second forming groove 32 when passing through the gap between the first forming roller 2 and the second forming roller 31, then the specific value of the time difference is counted, and the corresponding lateral adjustment information is found according to the preset time difference lateral adjustment table; the time difference lateral adjustment table contains the time difference and the corresponding lateral adjustment information.
[0082] S6: According to the transverse adjustment information, the electrically controlled transverse mechanism 9 is controlled to perform corresponding actions so that the time difference is zero and the adjustment is completed.
[0083] Specifically: the intelligent processing device 7 controls the electric screw to rotate a corresponding number of times according to the lateral adjustment information. The lateral adjustment information can be the number of rotations or angles of the electric screw. The lateral adjustment information can be obtained through laboratory testing. After the intelligent processing device 7 controls the electric screw of the electric-controlled lateral mechanism 9 to rotate a corresponding number of times according to the lateral adjustment information, the rotation between the first forming roller 2 and the second forming roller 31 is delayed or advanced accordingly, so that during the relative rotation of the first forming roller 2 and the second forming roller 31, the first forming groove 21 can continue to face the second forming groove 32, so that the time difference is zero, and the adjustment of the first forming roller 2 and the second forming roller 31 is completed.
[0084] Of course, in other embodiments, multiple first forming grooves 21 and multiple second forming grooves 32 are evenly arrayed, and the distances between the multiple rows of first forming grooves 21 along the axis of the first forming roller 2 are equal, then multiple laser emitting devices 86 can be provided, and the distance between two adjacent laser emitting devices 86 is equal to the distance between two adjacent rows of first forming grooves 21. Therefore, after the first forming roller 2 and the second forming roller 31 rotate one circle, it is determined whether the first laser incident information and the second laser incident information can be obtained simultaneously in this process, that is, in the time when the first forming roller 2 and the second forming roller 31 rotate one circle, there is one time difference in the multiple statistics, and the time between the acquisition time of the first laser incident information and the acquisition time of the second laser incident information is the time difference. If the difference is zero, it means that the first molding groove 21 can be opposite to the corresponding second molding groove 32 in the gap between the first molding roller 2 and the second molding roller 31. If the difference is not zero, it means that the first molding groove 21 cannot be opposite to the corresponding second molding groove 32. Then, by obtaining the shortest time difference, traversing the time difference lateral shift adjustment table through the shortest time difference, the lateral shift adjustment information is obtained, and the electric control lateral shift mechanism 9 is adjusted to further explain the principle of this embodiment. The main reason is that the circumferential distribution characteristics of the first molding groove 21 along the first molding roller 2 are further improved, so that the first molding groove 21 can be opposite to any second molding groove 32 in the gap between the first molding roller 2 and the second molding roller 31, so that the effect of all first molding grooves 21 and second molding grooves 32 facing each other can be achieved.
[0085] Record the acquisition time of the first laser incident information as the first recording time, record the acquisition time of the second laser incident information closest to the first recording time as the second recording time, and calculate the time difference between the first recording time and the second recording time. It should be noted that in this embodiment, the number of laser emitting devices 86 of the first forming roller 2 and the second forming roller 31 is N. For example, N can correspond to a number greater than 10. The time difference is recorded N times continuously to determine whether all time differences are greater than a preset error time value. The error time value is determined by personnel based on the processing error between the first forming roller 2 and the second forming roller 31. If it is greater than the preset error time value, the intelligent processing device 7 controls the prompt device to prompt personnel that the adjustable granulator is loose or the gear wear is abnormal, so that personnel can repair the equipment in time.
[0086] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
