Description

Technical Field

[0001] The present invention relates to the technical field of gypsum board production, and in particular to a speed-up formula matching system for a gypsum board high-speed production line. Background Art

[0002] The molding section of the gypsum board production line is the source of gypsum board production. The stability of the materials in the molding section directly determines the pass rate of the finished gypsum board. Therefore, the stability of the production line operation must be guaranteed as much as possible during the molding stage. During the gypsum board production process, the production operation stability of the gypsum board is easily affected by the speed of various metering equipment and transportation equipment. Generally, the feeding control and transportation speed are adjusted manually, and there is a lot of manual production intervention. It is impossible to automatically match the corresponding drive speed and feeding ratio and quantity according to the required production speed, which can easily affect the product quality of the gypsum board.

[0003] In this regard, the invention patent with publication number CN114311272B in the prior art provides a gypsum board high-speed production line speed-up formula matching system, which achieves the matching of gypsum production ingredient parameters and production speed, ensuring the stability of materials and speed.

[0004] During the entire gypsum production process, paper is generally fed at a low production line speed, and material unloading begins after the dry and wet materials stabilize. The speed is then gradually increased to the actual required production speed. The existing technology only considers the matching of materials and speed during stable operation, and does not consider the uniform distribution of gypsum ingredients on the production line during the speed-up process. If the speed is increased too quickly and the ingredients are not adjusted in time during the speed-up process, it will lead to untimely material feeding and a shortage of gypsum boards. If the speed is increased too slowly, it may cause excessive material accumulation on the forming table. Therefore, there is a problem of not being able to ensure the matching of adjustment parameters during the speed-up process. Summary of the Invention

[0005] To this end, the present invention provides a gypsum board high-speed production line speed-up formula matching system, which effectively solves the technical problem in the prior art that the speed-up process adjustment parameters cannot be matched.

[0006] To solve the above technical problems, the present invention specifically provides the following technical solutions: a gypsum board high-speed production line speed-up formula matching system, characterized by having:

[0007] A feeding module, which is in communication with the main control module, feeds gypsum, pulp water, and additives to the high-speed gypsum board production line and adjusts the gypsum board production process parameters according to the process formula and the phased batching parameters assigned by the main control module;

[0008] A main control module builds a gypsum board production matching model based on gypsum board transportation parameters and gypsum board production process parameters. The main control module reads the staged speed-up parameters and assigns them to the production line module, and reads the staged ingredient parameters and assigns them to the loading module. The main control module checks the speed-ingredient matching status at the speed-up stage node and starts the next speed-up stage if the matching status is complete;

[0010] A speed matching module sets a final speed value and a maximum speed-up time. The speed matching module determines a speed-up range based on the final speed value and the initial speed value, and determines the speed-up stages and the speed-up parameters for each stage based on the maximum speed-up time and the speed-up range analysis.

[0015]

[0016] Where ΔV is the speed difference, v n is the final value of speed, v0 is the initial value of speed;

[0017] Substitute the speed difference into the following formula to calculate the time difference of the speed-up phases and the total time of the speed-up phases:

[0018]

[0019] t z =t1+t2+…+t n ;

[0020] Where, t1=t2=…=t n , t1 is the time difference between stages;

[0023] Where, T max is the maximum acceleration time;

[0024] Establish matching constraints and determine whether the matching constraints are met:

[0025] A∈[A min , A max ];

[0026] Where A is the stage adjustment coefficient, A min 、A max All are adjustment coefficient thresholds;

[0027] Adjust the initial value n of the number of speed-up stages and repeat the above steps to screen all n values ​​that meet the time constraint and matching constraint;

[0028] The n value with the largest value is selected, and the speed difference, time difference and node speed value of each stage of speed-up are calculated based on the n value, and used as the stage-by-stage speed-up parameters.

[0029] Furthermore, before establishing the matching constraint, the adjustment coefficient threshold is determined, including the following steps:

[0034] The adjustment coefficient threshold is determined by analyzing the boundary values ​​of the first adjustment coefficient set and the second adjustment coefficient set.

[0035] Furthermore, establishing a matching constraint and determining whether the matching constraint is satisfied includes the following steps:

[0036] Substitute the initial plaster usage F0 and the stage node speed value (v0+ΔV) into the gypsum board production matching model to calculate the stage adjustment coefficient A.

[0037] Furthermore, the staged speed-up parameters are substituted into the gypsum board production matching model to calculate the ideal batching parameters of the speed-up stage nodes, and the staged batching parameters are determined based on the ideal batching parameters, including the following steps:

[0039] The ideal batching parameters are used as the batching parameters for different stages;

[0040] The ideal batching parameters include the ideal pulp water addition amount, the ideal plaster usage amount, and the ideal additive addition amount.

[0041] Furthermore, the ideal batching parameters of the speed-up phase nodes are set, and the acceleration of parameter changes is calculated:

[0042]

[0043] Where a c is the parameter change acceleration, c1 is the ideal batching parameter of the speed-up phase node, c0 is the initial batching parameter of the speed-up phase node, and t1 is the time difference between phases;

[0044] Conduct staged speed-up experiments based on parameter change acceleration and ideal batching parameters, record the actual batching adjustment time point after completing a single batching parameter adjustment, calculate the time difference between the actual batching adjustment time point and the speed-up stage node, and use it as the delay time;

[0045] Introduce a delay time, recalculate the parameter change acceleration and use it as a phased batching parameter:

[0046]

[0047] Where, t y is the delay time.

[0048] Furthermore, the feeding module includes several feeding lines arranged at the feeding port of the gypsum board production line;

[0049] A control valve is provided at the discharge end of the feeding line. A frequency converter is provided on the control valve. The frequency converter is communicated with the main control module and controls the opening and switching speed of the control valve according to the staged batching parameters read by the main control module.

[0053] Furthermore, a gypsum board production matching model is constructed based on the gypsum board transportation parameters and the gypsum board production process parameters, including the following steps:

[0054] Assuming the width of the gypsum board is a meter, a relationship model between the gypsum board transportation parameters and the gypsum board production process parameters is established to obtain a gypsum board production matching model;

[0056] The relationship model between the amount of plaster used and the transportation speed of the gypsum board production line is: F = ((A-1)*N+1)*(1+0.5%)*60*a*1000*V;

[0061] Among them, W 添 is the amount of additives added, and T is the ratio of the amount of plaster used to the amount of additives added.

[0062] Furthermore, the speed-batch matching status is checked at the speed-up phase nodes, including the following methods:

[0063] Before the main control module controls the loading module and the production line module to enter the next speed-up stage, checking whether the real-time stage node speed value and the real-time batching parameters of the speed-up stage node match the gypsum board production matching model;

[0064] If they match, the next speed-up phase will begin;

[0065] If there is no match, wait for the match before starting the next speed-up stage.

[0066] Compared with the prior art, the present invention has the following beneficial effects:

[0067] In the present invention, the speed-up stages and stage-by-stage speed-up parameters are determined by the speed matching module, and the gradual speed-up process of the gypsum board production line is realized through stage-by-stage speed-up.

[0072] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0073] like Figure 1As shown, the present invention provides a gypsum board high-speed production line speed-up formula matching system, which is equipped with a feeding module, a main control module, a production line module, a speed matching module and a batching module.

[0074] Among them, the feeding module is connected to the main control module for communication. The feeding module feeds gypsum, pulp water and additives to the gypsum board high-speed production line, and adjusts the gypsum board production process parameters according to the process formula and the phased batching parameters allocated by the main control module.

[0075] The main control module builds a gypsum board production matching model based on gypsum board transportation parameters and gypsum board production process parameters. The main control module reads the phased speed-up parameters and assigns them to the production line module, and reads the phased material parameters and assigns them to the loading module. The main control module verifies the speed-material matching status at the speed-up phase node and starts the next speed-up phase if the matching status is complete.

[0076] The production line module is connected to the main control module. During the production process of gypsum boards, the production line module transports the gypsum boards and adjusts the production line transportation speed according to the phased speed-up parameters assigned by the main control module.

[0077] The speed matching module sets the final speed value and the maximum speed-up time. The speed matching module determines the speed-up range based on the final speed value and the initial speed value, and determines the speed-up stages and stage-by-stage speed-up parameters based on the maximum speed-up time and the speed-up range analysis.

[0078] The batching module calls the gypsum board production matching model, and substitutes the staged speed-up parameters into the gypsum board production matching model to calculate the ideal batching parameters of the speed-up stage nodes, and determines the staged batching parameters based on the ideal batching parameters.

[0079] Among them, the speed matching module mainly analyzes the speed-up parameters in the speed-up stages, and the batching module mainly analyzes the batching parameters in the speed-up stages.

[0080] In the present invention, the speed-up stages and stage-by-stage speed-up parameters are determined by the speed matching module, and the gradual speed-up process of the gypsum board production line is realized through stage-by-stage speed-up. In the stage-by-stage speed-up process, the stage-by-stage batching parameters are analyzed and allocated. In each speed-up stage, the batching and speed are matched. In addition, the speed-batch matching status is checked at the speed-up stage node, and the next speed-up stage is started when it is fully matched, so as to ensure the stable operation of the entire speed-up process.

[0081] In the present invention, the loading module loads gypsum, pulp water and additives into the gypsum board high-speed production line. The loading module generally includes several loading lines arranged at the feed inlet of the gypsum board production line, usually three loading lines, corresponding to the gypsum loading line, pulp water loading line and additive loading line respectively. A control valve is provided at the discharge end of the loading line, and a frequency converter is provided on the control valve. The frequency converter is communicated with the main control module and controls the opening and switching speed of the control valve according to the staged batching parameters read by the main control module.

[0082] The production line module transports the gypsum boards during the gypsum board production process and adjusts the production line transportation speed according to the staged speed-up parameters assigned by the main control module. Specifically, the production line module includes a conveyor belt and an open roller. A number of evenly distributed conveyor rollers are arranged in the open roller. The conveyor rollers are connected to a drive motor. The drive motor drives the conveyor belt forward through the conveyor rollers. The drive motor is communicated with the main control module and controls the rotation speed of the conveyor rollers according to the staged speed-up parameters read by the main control module.

[0083] In the present invention, the most important thing is to set the final speed value and the maximum acceleration time through the speed matching module. The speed matching module determines the acceleration range according to the final speed value and the initial speed value, and determines the acceleration stages and stage-by-stage acceleration parameters based on the maximum acceleration time and the speed-up range analysis. Among them, the final speed value and the maximum acceleration time are both set values. The final speed value is the final operating speed of the production line module, and the maximum acceleration time is the maximum value of the time required for the acceleration process.

[0084] Based on the maximum speed-up time and speed-up range analysis, the speed-up stages and stage-by-stage speed-up parameters are determined, including the following steps:

[0085] Set the acceleration a t ;

[0086] Set an initial value n for the number of speed-up stages and calculate the speed difference of the speed-up stages using the following formula:

[0087]

[0088] Where ΔV is the speed difference, v n is the final value of speed, v0 is the initial value of speed;

[0089] Substitute the speed difference into the following formula to calculate the time difference of the speed-up phases and the total time of the speed-up phases:

[0090]

[0091] t z =t1+t2+…+t n ;

[0092] Where, t1=t2=…=tn , t1 is the time difference between stages;

[0093] Establish time constraints and determine whether they are met:

[0094] t1+t2+…+t n <T max ;

[0095] Where, T max is the maximum acceleration time;

[0096] Establish matching constraints and determine whether the matching constraints are met:

[0097] A∈[A min , A max ];

[0098] Where A is the stage adjustment coefficient, A min 、A max All are adjustment coefficient thresholds;

[0099] Adjust the initial value n of the number of speed-up stages and repeat the above steps to screen all n values ​​that meet the time constraint and matching constraint;

[0100] The n value with the largest value is selected, and the speed difference, time difference and node speed value of each stage of speed-up are calculated based on the n value, and used as the stage-by-stage speed-up parameters.

[0101] The above process is the process of screening the n value. Assuming that the n value with the largest value screened out is 5, there are 5 speed-up stages, and the entire speed-up process is completed through five stages of speed-up.

[0102] In the above embodiment, in the process of analyzing the final n value, satisfying the time constraint requires that the time consumed by the entire speed-up process is less than the maximum speed-up time, and satisfying the matching constraint requires that the corresponding gypsum board transportation parameters and gypsum board production process parameters in the speed-up stages can be matched, and under this matching state, there will be no shortage of materials.

[0103] In order to satisfy the matching constraint, the stage adjustment coefficient needs to be within the adjustment coefficient threshold range. Before establishing the matching constraint and determining whether the matching constraint is satisfied, the adjustment coefficient threshold needs to be determined first.

[0104] Specifically, before establishing the matching constraint, the adjustment coefficient threshold is determined, including the following steps:

[0105] Conduct gypsum production matching experiments based on different plaster usage and production line transportation speeds;

[0106] Observe the shortage of gypsum boards and the material stacking at the loading end, and record abnormal and normal conditions;

[0107] Substituting the amount of plaster of Paris used and the transportation speed of the production line under abnormal conditions into the gypsum board production matching model, and calculating the first adjustment coefficient to form a first adjustment coefficient set;

[0108] Substituting the normal usage of plaster of Paris and the transportation speed of the production line into the gypsum board production matching model, and calculating the second adjustment coefficient to form a second adjustment coefficient set;

[0109] The adjustment coefficient threshold is determined by analyzing the boundary values ​​of the first adjustment coefficient set and the second adjustment coefficient set.

[0110] The situation of lack of gypsum board and accumulation of materials are set as abnormal situations, and the situation of no lack of gypsum board and accumulation of materials are set as normal situations. The situation of lack of material and accumulation of materials can be monitored by using camera elements, infrared sensor elements, etc.

[0111] After the above steps, the values ​​outside the adjustment coefficient threshold area are generally abnormal, and the values ​​within the adjustment coefficient threshold are generally normal.

[0112] Generally, each speed-up phase takes the same amount of time. Figure 2 For example, a~b is the first speed-up stage, and b~c is the second speed-up stage. During the a~b process, if we want to determine whether the matching constraint is met in a certain speed-up stage, we should assume the maximum batching adjustment delay, that is, assuming that the speed is increased at point a and the batching adjustment is started at point b. In this case, the amount of gypsum used at point b is the same as that at point a, which is the initial gypsum usage F0. If the gypsum usage corresponding to point b and the stage node speed value meet the gypsum board production matching model at this time, and the calculated A value meets the matching constraint, then even if there is a delay in batching adjustment in this speed-up stage, there will be no material piling or shortage.

[0113] Specifically, establishing a matching constraint and determining whether the matching constraint is satisfied includes the following steps:

[0114] The initial plaster usage F0 and the staged node speed value (v0+ΔV) are substituted into the gypsum board production matching model to calculate the stage adjustment coefficient A. The calculated A value is then used to determine whether it meets the matching constraints.

[0115] In the above embodiment, assuming that the speed is increased at point a and the batching is adjusted at point b, then at point b, it is determined whether the batching and speed match. If the matching constraint is met, it means that point b meets the matching constraint. If point b meets the matching constraint, the time between a and b must also meet the matching constraint.

[0116] In order to further ensure the synchronous adjustment of ingredients and speed and further optimize the matching effect, the present invention also proposes the following methods:

[0117] Substituting the staged speed-up parameters into the gypsum board production matching model to calculate the ideal batching parameters for the speed-up stage nodes, and determining the staged batching parameters based on the ideal batching parameters, including the following steps:

[0118] Substitute the speed values ​​of the phased nodes into the gypsum board production matching model to calculate the ideal batching parameters of the speed-up phased nodes;

[0119] The ideal batching parameters are used as the batching parameters for different stages;

[0120] Among them, the ideal ingredient parameters include the ideal amount of pulp water added, the ideal amount of gypsum used, and the ideal amount of additives added.

[0121] Set the ideal batching parameters for the speed-up phase nodes and calculate the acceleration of parameter changes:

[0122]

[0123] Where a c is the parameter change acceleration, c1 is the ideal batching parameter of the speed-up phase node, c0 is the initial batching parameter of the speed-up phase node, and t1 is the time difference between phases;

[0124] Conduct staged speed-up experiments based on parameter change acceleration and ideal batching parameters, record the actual batching adjustment time point after completing a single batching parameter adjustment, calculate the time difference between the actual batching adjustment time point and the speed-up stage node, and use it as the delay time;

[0125] Introduce a delay time, recalculate the parameter change acceleration and use it as a phased batching parameter:

[0126]

[0127] Where, t y is the delay time.

[0128] In the above embodiment, the main process is as follows: in the speed-up phases from a to b, the node speed value of point b is substituted into the gypsum board production matching model to calculate the ideal batching parameters of point b. Specifically, after the ideal batching parameters of point b are obtained, the batching is adjusted based on the ideal batching parameters of point b. However, due to factors such as batching delay and data transmission delay during the batching adjustment process, it is not necessarily possible to ensure that the ideal batching parameters are exactly achieved at point b. Therefore, Figure 3 For example, assuming that the batching adjustment is completed at point b and the batching adjustment starts at point a, calculate the ideal parameter change acceleration a during the process from a to b. c, and according to the ideal parameter change acceleration a c After the actual adjustment of the ingredients, the adjustment is completed at point y, and there is a time difference with point b. This time difference is the delay time t y In actual operation, it is impossible to adjust the ingredients instantly at point a. Assuming that the adjustment is actually started at point x, the time from a to x must be equal to the time from b to y, which is the delay time t y , then the time of the process from x to b is the actual time of batch adjustment, and the parameter change acceleration a is recalculated based on the actual time of batch adjustment. c , it is closer to the ideal parameter change acceleration and is more likely to reach the ideal batching parameters at point b. In practical applications, batching adjustments are also made based on the ideal batching parameters and the specific parameter change acceleration.

[0129] The gypsum board production matching model is constructed based on the gypsum board transportation parameters and gypsum board production process parameters, including the following steps:

[0130] Assuming the width of the gypsum board is a meter, a relationship model between the gypsum board transportation parameters and the gypsum board production process parameters is established to obtain a gypsum board production matching model;

[0131] The gypsum board production process parameters include the amount of gypsum used, the amount of pulp water added, and the amount of additives added. The gypsum board production matching model includes the relationship model between the amount of paris plaster used and the transportation speed of the gypsum board production line, the relationship model between the amount of pulp water added and the transportation speed of the gypsum board production line, and the relationship model between the amount of additives added and the transportation speed of the gypsum board production line.

[0132] The relationship model between the amount of gypsum used and the transportation speed of the gypsum board production line is: F = ((A-1)*N+1)*(1+0.5%)*60*a*1000*V;

[0133] Where, F is the amount of gypsum used, A is the adjustment coefficient, N is the quality of gypsum, and V is the transportation speed of the production line;

[0134] The relationship model between the amount of pulp water added and the transportation speed of the production line is: W 水 =G*((A-1)*N+1)*(1+0.5%)*60*a*1000*V;

[0135] Among them, W 水 is the amount of pulp water added, G is the water-paste ratio;

[0136] Relationship model between additive dosage and production line transport speed: W 添 =T*((A-1)*N+1)*(1+0.5%)*60*a*1000*V;

[0137] Among them, W添 is the amount of additives added, and T is the ratio of the amount of plaster used to the amount of additives added.

[0138] In the above embodiment, the process of substituting the initial plaster usage F0 and the staged node speed value (v0+ΔV) into the gypsum board production matching model is to substitute them into the relationship model between the plaster usage and the transportation speed of the gypsum board production line, wherein the A value in the relationship model can be determined based on experiments to determine the optimal value of A.

[0139] In the present invention, the speed-ingredient matching state is checked at the speed-up stage node, including the following methods:

[0140] Before the main control module controls the loading module and the production line module to enter the next speed-up stage, it checks whether the real-time stage node speed value and the real-time batching parameters of the speed-up stage node match the gypsum board production matching model;

[0141] If they match, the next speed-up phase will begin;

[0142] If there is no match, wait for the match before starting the next speed-up stage.

[0143] Under normal circumstances, when the speed-batch mismatch occurs, the system runs at the current stage node speed value for a period of time, waiting for the real-time batching parameters to reach the ideal batching parameters. When the real-time stage node speed value and the real-time batching parameters of the speed-up stage node have matched the gypsum board production matching model, the next speed-up stage can be started.

The scope of protection of the present application is defined by the claims.
