Detailed Description
The embodiments of the invention will be described in detail below with reference to the accompanying drawings, but the invention can be embodied in many different forms, which are defined and covered by the following description.
As shown in fig. 1, a first embodiment of the present invention provides an intelligent control method for a rice huller, which includes the following steps:
step S1: the equipment is powered on, and a motor power switch is automatically started;
step S2: obtaining an operation mode before the last automatic shutdown to continue operation, wherein the operation mode comprises a first operation mode and a second operation mode, the first operation mode takes a movable roller as a fast roller and takes a fixed roller as a slow roller, the second operation mode takes the movable roller as the slow roller and takes the fixed roller as the fast roller, and standard working parameters in the operation mode comprise reference operation frequency, reference roller combination pressure, linear speed difference, set current, operation set time and actual operation time of the fast roller and the slow roller;
step S3: and recording the accumulated actual running time of the current running mode, and automatically switching to another running mode to work when the accumulated actual running time reaches the running set time.
It can be understood that, in the intelligent control method of the rice huller of this embodiment, after the device is powered on and automatically starts to work, the operation mode before the last automatic shutdown is automatically obtained to continue to operate, and the accumulated actual operation time of the current operation mode is recorded, the accumulated actual operation time includes both the operation time before the last automatic shutdown and the operation time, when the accumulated actual operation time reaches the operation setting time corresponding to the operation mode, the operation mode is automatically switched to another operation mode to work, so that the operation frequency of the fixed roller and the movable roller is periodically exchanged, that is, the fixed roller and the movable roller work as fast rollers to realize the periodic exchange, the rubber layer wear degrees of the two rubber rollers are similar, and the shorter the operation setting time is, the higher the exchange frequency of the two rubber rollers is, the more the rubber layer wear degrees of the two rubber rollers tend to be consistent, so that only one time of replacing the pair of rubber rollers of the rice huller is needed, the high shelling efficiency is ensured, the personnel maintenance time and the labor intensity are reduced, the continuous stability of the grain production flow is ensured, and the energy consumption is reduced.
It can be understood that after equipment is powered on, the fixed roller motor and the movable roller motor are automatically started, wherein the fixed roller motor drives the fixed roller to rotate through the belt, and the movable roller motor drives the movable roller to rotate through the belt. In addition, during the working process, the movable roller is pulled by the air cylinder to swing back and forth, so that the movable roller and the fixed roller perform tangential roller closing action to process grains or separate from the fixed roller.
Then, using the programAnd automatically acquiring an operation mode before the last automatic stop to continue operation, wherein the operation mode specifically comprises a first operation mode and a second operation mode, the first operation mode takes the movable roller as the fast roller and takes the fixed roller as the slow roller, and the second operation mode takes the movable roller as the slow roller and takes the fixed roller as the fast roller. The fast roller and the slow roller are relative concepts, and are specifically defined by the speed of the rotating speed of the rubber roller, for example, when the rotating speed of the movable roller is greater than that of the fixed roller, the movable roller is the fast roller, the fixed roller is the slow roller, and when the rotating speed of the movable roller is less than that of the fixed roller, the movable roller is the slow roller, and the fixed roller is the fast roller. Each operation mode comprises standard working parameters (namely initial working parameters), and the standard working parameters comprise reference operation frequency, reference roller combination pressure, linear speed difference, set current, operation set time and actual operation time of the fast roller and the slow roller, wherein the reference operation frequency, the reference roller combination pressure and the operation set time of the fast roller and the slow roller are preset, and the actual operation time is obtained through actual recording. For example, in the first operation mode, the reference operation frequency of the fixed roller is Vg1The reference operating frequency of the movable roller is Vh1The operation is set to T1The reference pressure of the combined roller is P10The actual running time is t1(ii) a And in the second operation mode, the reference operation frequency of the fixed roller is Vg2The reference operating frequency of the movable roller is Vh2The operation is set to T2The reference pressure of the combined roller is P20The actual running time is t2The specific values of the parameters can be set according to actual conditions.
And then, recording the accumulated actual operation time of the current operation mode in the machining process, namely simultaneously including the operation time before the last automatic stop and the operation time of the current time, and automatically switching to another operation mode to work when the accumulated actual operation time reaches the operation set time. For example, when the operation mode before the last automatic stop is the first operation mode, in which the movable roll operates as the fast roll, the accumulated actual operation time in the first operation mode reaches the operation set time T1At that time, it means that the movable roller acts as a fastThe time of roller work reaches and predetermines long time, the movable roll is great relatively for the fixed roll adhesive layer wearing and tearing, will switch over to the second operation mode operation this moment, the fixed roll is as fast roller work promptly, thereby the degree of wear between balanced movable roll and the fixed roll, change the operation mode through periodic cycle, make the degree of wear of movable roll and fixed roll equivalent, treat when both degree of wear reach the alarm value, then change a pair of new rubber roll can, a pair of rubber roll only need carry out once in whole work life cycle tear open and trade can. Therefore, the operation frequency is periodically exchanged through the fixed roller and the movable roller, namely the fixed roller and the movable roller work as the fast rollers to realize the periodic exchange, the abrasion degrees of the rubber layers of the two rubber rollers are close, and the shorter the operation set time is, the higher the exchange frequency of the two rubber rollers is, the more the abrasion degrees of the rubber layers of the two rubber rollers tend to be consistent, so that the situation that a pair of rubber rollers of the rice huller only needs to be disassembled and replaced once from the replacement to the completion of the abrasion of the rubber layers is realized, the higher hulling efficiency is ensured, the personnel maintenance time and the labor intensity are reduced, the continuity and the stability of the grain production flow are ensured, and the energy consumption is reduced.
Optionally, as shown in fig. 2, in another embodiment of the present invention, after step S2, the intelligent control method of the rice huller further includes the following steps:
step S2 a: and detecting a linear displacement value of the movable roller connecting plate in the machining process, calculating to obtain the actual diameter of the rubber roller in the machining process based on the linear displacement value, adjusting the operating frequencies of the fast roller and the slow roller based on the actual diameter of the rubber roller and the frequency value corresponding to the linear speed difference, and storing the adjusted actual operating frequency into a corresponding operating mode.
It can be understood that the linear displacement value of the movable roller connecting plate can be reflected by detecting the linear displacement value of the movable roller connecting plate in the processing process, so that the actual diameter of the rubber roller can be calculated based on the linear displacement value, the abrasion degree of the rubber roller can be calculated based on the comparative analysis of the actual diameter of the rubber roller and the standard diameter, the running frequency of the fast roller and the slow roller can be automatically adjusted based on the abrasion degree of the rubber roller, the trend that the linear speed sum and the linear speed difference between two rubber rollers are constantly reduced due to the fact that the rubber roller in a pair of processing is abraded along with the rubber layer and the diameter of the rubber roller is gradually reduced can be effectively eliminated, the linear speed sum and the linear speed difference between the two rubber rollers are kept basically constant, and the shelling efficiency is effectively improved. And storing the actual operating frequency of the adjusted fast roller and slow roller into the corresponding operating mode. In addition, because the movable roller and the fixed roller work as the fast rollers to carry out periodic cycle interchange, the abrasion degree of the two rubber rollers can be approximately the same in the processing process, and the actual diameters of the two rubber rollers can also be approximately equal.
The actual diameter of the rubber roller in the processing process is calculated based on the following formula:
Dy0＝(Ls-L0-Wg)*K+D0
wherein D isy0Denotes the actual diameter of the rubber roller during processing, D0Denotes the diameter of a standard rubber roller, LsThe distance value between the movable roller connecting plate and the fixed detection point in the machining process is a factory calibration value L0Represents the distance value between the movable roller connecting plate and the fixed detection point when the standard new rubber roller is in roller combination contact and is not fed and processed, WgIndicate cereal grain thickness, K indicates the distance value between the processing in-process activity roller connecting plate to the fixed point and the ratio coefficient between the concentric distance of fast roller and slow roller, and this coefficient is measured according to rice huller assembly rubber roller seat wearing and tearing test and obtains, generally takes 0.5 ~ 0.6. Wherein (L)s-L0-Wg) I.e. the linear displacement value of the movable roll connecting plate during the machining process. In other embodiments of the present invention, the linear displacement value of the movable roller connecting plate may also be directly detected.
In addition, the operating frequencies of the fast and slow rolls are adjusted based specifically on the following equations:
Vg11＝(D0/Dy0)*Vg1-Vx
Vh11＝(D0/Dy0)*Vh1+Vx
Vg22＝(D0/Dy0)*Vg2+Vx
Vh22＝(D0/Dy0)*Vh2-Vx
wherein, Vg11Indicating the actual operating frequency, V, of the adjusted fixed roller in the first operating modeg1Indicating the reference operating frequency, V, of the fixed roller in the first operating modeg22Indicating the actual operating frequency, V, of the adjusted fixed roller in the second operating modeg2Indicating the reference operating frequency, V, of the fixed roller in the second operating modeh11Representing the actual operating frequency, V, of the adjusted movable roller in the first operating modeh1Indicating the reference operating frequency, V, of the movable roller in the first operating modeh22Indicating the actual operating frequency, V, of the adjusted movable roller in the second operating modeh2Indicating the reference operating frequency, V, of the movable roller in the second operating modexRepresenting the frequency value associated with the linear velocity difference, e.g. V for every 0.1m/s of linear velocity differencexIs + -1 (Hz), i.e., +1Hz is increased to the fast roller frequency, the fast roller linear speed is increased, minus 1Hz is increased to the slow roller frequency, the slow roller linear speed is reduced, in the invention, the set linear speed difference is centered at 3.1m/s and is adjustable between 2.6m/s and 3.6m/s, for example, 3.1m/s corresponds to VxThe operation frequency of the fast and slow rollers is kept constant at 0Hz, and 3.6m/s is (3.6-3.1) × 10 is 5(Hz), the operation frequency of the fast rollers is automatically increased by 5Hz, and the operation frequency of the slow rollers is automatically decreased by 5 Hz. And storing the operating frequencies of the fast roller and the slow roller as actual operating parameters into corresponding operating modes to replace the initial reference frequency.
For example, the standard diameter D of the rubber roller0255mm, factory calibration value L0110mm, factory setting K0.6, grain thickness Wg1mm, the real-time value L of the linear displacement of the movable roller connecting plate in automatic processing after the user replaces the new rubber rollers102mm, fixed roll reference frequency V in a first mode of operationg136Hz, moving roll reference frequency Vh143Hz, fixed roll reference frequency V in the second operating modeg243Hz, moving roll reference frequency Vh2The line speed difference, at 36Hz, runs at 3.3m/s, calculated from the above equation respectively as follows,
actual diameter D of rubber rollery0＝(102-110-1)×0.6+255＝249.6mm；
Actual operating frequency V of the fixed roller in the first operating modeg11＝255/249.6×36-(3.3-3.1)×10＝34.78Hz；
Actual operating frequency V of the movable roller in the first operating modeg22＝255/249.6×43+(3.3-3.1)×10＝45.93Hz；
Actual operating frequency V of the fixed roller in the second operating modeg11＝255/249.6×43+(3.3-3.1)×10＝45.93Hz；
Actual operating frequency V of the movable roller in the second operating modeg22＝255/249.6×36-(3.3-3.1)×10＝34.78Hz。
Optionally, as shown in fig. 3, in another embodiment of the present invention, after step S2, the intelligent control method of the rice huller further includes the following steps:
step S2 b: detecting the real-time working current value of a fast roller motor in the machining process, comparing the real-time working current value with the set current range of the first operation mode or the second operation mode, when the real-time working current value exceeds the upper limit value of the set current range, automatically reducing the roller combination working pressure on the basis of the reference roller combination pressure, when the real-time working current value is smaller than the lower limit value of the set current range, automatically increasing the roller combination working pressure on the basis of the reference roller combination pressure, and storing the adjusted roller combination working pressure into the corresponding operation mode.
It can be understood that after the rice huller automatically starts to work, the real-time working current value I of the fast roller motor (movable roller motor or fixed roller motor) in the processing process is automatically detected by utilizing a programsjIs shown bysjComparing with the set current range if Isj＞I1+IsOr Isj＞I2+IsBased on the reference closing pressure P10/P20Automatically reducing the working pressure of the combined rolls on the basis, e.g. by P20-PtWorking with a large and small closing roll pressure, if Isj＜I1-IxOr Isj＜I2-IxThen based on the reference pressure P of the combined roller10/P20Automatically increasing the working pressure of the combined rolls on the basis thereof, e.g. by P10+PtThe size of the roller can work under the pressure of the combined roller, so that the working pressure between the two rubber rollers can be automatically adjusted according to the working current of the fast roller motor in the first running mode or the second running mode, the situation that the actual diameter of the rubber rollers is not matched with the pressure of the combined roller, the shelling rate is reduced due to insufficient pressure, or the pressure is too large, broken rough rice is increased, and the problem that the motor is overloaded due to the fact that the pressure set value is artificially modified after the feeding amount is increased and the shelling rate is reduced can be effectively solved. Wherein, IsIndicating the actual operating current of the fast-stick motor, I1A set current value, I, representing a first operating mode2A set current value, I, representing the second operating modesRepresents the upper limit value of the deviation of the set current value, IxIndicating a lower limit value of deviation of the set current value, P10Reference nip pressure, P, representing a first mode of operation20Reference nip pressure, P, representing the second mode of operationtIndicating the voltage regulation value.
Optionally, the step S2 further includes the following steps after the device is powered on:
and automatically identifying whether the rubber roller is replaced, if so, restarting to operate according to new working parameters corresponding to the actual diameter of the new rubber roller calculated during the automatic operation, and if not, acquiring the actual working parameters of the operation mode during the last automatic shutdown to continue to operate.
It can be understood that, in the above step S2a, it is realized that the operation frequency of the fast roll and the slow roll is adjusted based on the detected real-time value of the linear displacement of the movable roll connecting plate during the processing, so that the operation parameters of the operation mode before the last automatic stop acquired after the apparatus is powered on are actual operation parameters, not initial standard operation parameters.
