Description
Technical Field
The invention relates to the technical field of plastic extruding machines, in particular to a plastic extruding speed compensation method, a plastic extruding speed compensation system, computer equipment and a storage medium.
Background
The stability of the outer diameter of the cable is an important measure of the performance of the cable. When the outer diameter of the optical cable is unstable, the outer diameter of the optical cable is substantially small and large along the length direction, and the overall outer diameter is not uniform, which is a quality problem which always troubles manufacturers. Because each optical cable has the standard outer diameter, the large optical cable wastes materials and can cause the possibility of being incapable of construction, and the small optical cable causes the optical cable to be too thin, thereby being easy to lacerate and pull.
In normal production, the extrusion speed of the extruder determines the outer diameter of the cable at a fixed production speed. Specifically, in the initial production stage, the production speed and the extrusion speed are matched to appropriate outer diameters under the conditions of low speed and single action, for example, when the production speed is 10m/min, the extrusion speed is adjusted to 5r/min, and the outer diameter of the optical cable reaches a qualified value, that is, if the outer diameter of the optical cable is required to be qualified, the production speed and the extrusion speed must be 2: 1, switching to linkage (the linkage is the ratio of the fixed production speed to the extrusion molding speed, namely when the production speed is increased to 100m/min, the extrusion molding speed is increased to 50r/min according to the ratio of 2: 1), and then increasing the speed to 100m/min for production after switching linkage, and then according to the ratio of 2: the ratio of 1 theoretically indicates that the outer diameter of the optical cable in each speed section is within the qualified range, but due to the influences of factors such as actual environment, temperature, mechanical abrasion, raw material quality and the like, the outer diameter of the optical cable in each speed section is not completely within the qualified range in the actual situation.
At present, the existing control schemes for the stability of the outer diameter of the optical cable are mainly divided into two schemes, one scheme is that whether the outer diameter of the optical cable is larger or smaller is judged manually in a visual observation mode, and the extrusion molding speed is manually modified when the outer diameter is larger or smaller so as to achieve the purpose of unifying the outer diameter, but the biggest defect of the scheme is that manual operation is needed, manpower is consumed, and certain hysteresis is provided; the other is that in the speed control program, the speed is enlarged or reduced, for example, the outer diameter is known to be smaller than 0.2mm at the speed of 30m/min, the extrusion speed is 20r/min, the outer diameter reaches the normal value when the extrusion speed reaches 22r/min through debugging, the speed assignment value is multiplied by a coefficient in the program control, namely the original speed is multiplied by the coefficient to assign the extrusion speed, but the biggest defect of the scheme is that the extrusion speed has jumpy change, namely the extrusion speed in the example is suddenly changed from 20r/min to 22r/min, and the outer diameter inevitably has a sudden change.
Therefore, how to improve the existing control scheme for the stability of the outer diameter of the optical cable, or provide a new control scheme for the stability of the outer diameter of the optical cable, is a technical problem to be solved urgently by those skilled in the art.
The above information is given as background information only to aid in understanding the present disclosure, and no determination or admission is made as to whether any of the above is available as prior art against the present disclosure.

When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example one
In view of the defects of the prior art, the inventor of the invention actively researches and innovates based on abundant practical experience and professional knowledge in many years of the industry and by matching with the application of the theory, so as to create a feasible control technology for the stability of the outer diameter of the optical cable, and the optical cable has higher practicability. After continuous research, design and repeated trial and improvement, the invention with practical value is finally created.
Referring to fig. 1, fig. 1 is a schematic flow chart of an extrusion speed compensation method according to an embodiment of the present invention, the method is applied to a scenario where an outer diameter of an optical cable is unstable when the optical cable is produced by an extruder, and the method is performed by an extrusion speed compensation system, which may be implemented by software and/or hardware, and integrated inside the extruder or a controller thereof. As shown in fig. 1, the extrusion speed compensation method may include the steps of:
s101, obtaining a preset relational mapping table, wherein the relational mapping table records a plurality of theoretical extrusion molding speeds which are sequentially increased progressively according to a set value, and a production speed, an actual extrusion molding speed and a compensation speed which correspond to the theoretical extrusion molding speeds.
It should be noted that, as mentioned in the background, if the production rate is set in accordance with the theoretical extrusion rate at 2: the ratio of 1, the outer diameter of the optical cable produced theoretically at each theoretical extrusion speed is within the acceptable range, but this is not the case in practice, and reference is made to the example of table 1 below.
Table 1:
as can be seen from table 1, although the extrusion speed and the production speed are in a linear function relationship, the outer diameter of the extrusion speed is not qualified, that is, each theoretical extrusion speed is not equal to the actual extrusion speed when the outer diameter is qualified, so that the theoretical extrusion speed needs to be compensated, and the compensation speed corresponding to each theoretical extrusion speed can be referred to the following table 2 (i.e., the map of the embodiment).
Table 2:
as can be seen from Table 2, at a production speed of 20m/min, the theoretical extrusion speed is 10r/min, but the outer diameter of the optical cable is unqualified and needs to be increased to 11.9r/min, the outer diameter of the optical cable is qualified, namely 1.9r/min needs to be compensated under the condition of the theoretical extrusion speed, and other speed sections are the same. If the method in the background art is used, the compensation is directly performed at 5r/min, 10r/min and the like, for example, 1.9r/min is added on the basis of 10r/min to reach 11.9r/min, and the speed sections between 5r/min and 10r/min, for example, the speed sections of 9r/min, 8r/min, 7r/min and the like, cannot be compensated, so that the problem of speed mutation exists. Therefore, the problem to be solved by the present embodiment is how to compensate each speed segment, so as to prevent the sudden speed change.
In this embodiment, before the step S101, the method further includes:
and the relational mapping table is established and stored in advance.
The specific number of theoretical extrusion speeds set in the map and the set values at the time of successive increments are arbitrarily set by a skilled person. The actual extrusion speed, the compensation speed, corresponding to each theoretical extrusion speed is obtained by the skilled person based on specific experimental results.
In this example, the set values at which the theoretical extrusion speeds exemplified in tables 1 and 2 are sequentially increased are 5, which means that the difference between every two adjacent theoretical extrusion speeds is 5r/min, that is, a compensation is made every 5 r/min. Of course, if the accuracy requirement is not high, and only one compensation is required at an interval of 10r/min, the set values at which the theoretical extrusion speeds illustrated in tables 1 and 2 are sequentially increased may be changed from 5 to 10, but as the actual requirement, 5r/min is sufficient, the smaller the set value, the higher the accuracy.
S102, determining the interval where the theoretical extrusion molding speed to be compensated is located by searching the relational mapping table, and calculating the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated according to the following compensation calculation formula:
(r2-r1)*(a-b)/c+r1+a；
wherein r1 is the compensation speed that theoretical extrusion molding speed that is less corresponds in the interval of theoretical extrusion molding speed place of waiting to compensate, r2 is the compensation speed that theoretical extrusion molding speed that is great corresponds in the interval of theoretical extrusion molding speed place of waiting to compensate, a is the theoretical extrusion molding speed of waiting to compensate, b is the theoretical extrusion molding speed that is less in the interval of theoretical extrusion molding speed place of waiting to compensate, c is the setting value when theoretical extrusion molding speed increases gradually in proper order in the relational mapping table.
It should be noted that the determination of the interval where the theoretical extrusion molding speed to be compensated is located is to determine which two theoretical extrusion molding speeds in the map table the theoretical extrusion molding speed to be compensated is located between.
In order to show the implementation of the embodiment of the present invention more clearly, a detailed description is given below by way of a specific example.
Assuming that the theoretical extrusion speed to be compensated is 17r/min, it can be determined from table 2 (the map of relations) that 17r/min belongs to the interval of 15r/min to 20r/min, and then r1 in the compensation calculation formula is 1.7 corresponding to 15r/min, r2 is-0.9 corresponding to 20r/min, a is 17r/min, b is the smaller theoretical extrusion speed in the interval of 15r/min to 20r/min, i.e. 15r/min, c is the set value when the theoretical extrusion speeds in table 2 sequentially increase, i.e. 5, so the compensation calculation formula is as follows: -0.9-1.7 x (17-15)/5+1.7+17 ═ 17.66r/min, i.e. the actual extrusion speed compensated for at a theoretical extrusion speed to be compensated of 17r/min is 17.66 r/min.
In this embodiment, after the step S102, the method further includes:
and updating the calculated theoretical extrusion molding speed to be compensated and the compensated actual extrusion molding speed corresponding to the theoretical extrusion molding speed to be compensated into the relational mapping table.
It should be noted that the advantage of updating the calculated record into the map is that subsequent calculations need not be repeated if there is the same theoretical extrusion speed to be compensated.
In addition, after the actual extrusion speed is obtained through calculation, the process that the PLC controls the extrusion speed to change is a process of converting digital quantity into analog quantity, namely the range of the digital quantity of a hardware interface address is 0-27648 and corresponds to 0-10V of hardware interface voltage, therefore, the actual extrusion speed obtained through calculation is firstly converted into a digital quantity signal in a program, the conversion relation is 0-50r and corresponds to 0-27648, and the actual extrusion speed (27648/50) is the set speed of the final motor controller.
According to the extrusion molding speed compensation method provided by the embodiment of the invention, the actual extrusion molding speed corresponding to any theoretical extrusion molding speed is determined through the pre-established relational mapping table and the compensation calculation formula, the theoretical extrusion molding speed is compensated more reasonably, the problem of speed mutation during compensation can be prevented, the stability of the outer diameter of the optical cable is ensured, and meanwhile, the automation degree and the efficiency are very high because manual participation is not needed.
Example two
Referring to fig. 2, fig. 2 is a schematic flow chart of an extrusion speed compensation method according to an embodiment of the present invention. On the basis of the technical solution provided in the first embodiment, the step S102 "determining the interval where the theoretical extrusion speed to be compensated is located by searching the map, and calculating the compensated actual extrusion speed according to the following compensation calculation formula" is further optimized. The same or corresponding explanations of terms as those in the above embodiments are omitted here, namely:
judging whether a theoretical extrusion molding speed identical to the theoretical extrusion molding speed to be compensated exists or not by searching the relational mapping table;
if so, taking the actual extrusion molding speed corresponding to the theoretical extrusion molding speed which is the same as the theoretical extrusion molding speed to be compensated in the relational mapping table as the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated;
if not, determining the interval of the theoretical extrusion molding speed to be compensated by searching the relational mapping table, and calculating the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated according to the following compensation calculation formula.
Based on the above optimization, as shown in fig. 2, the extrusion speed compensation method provided in this embodiment may specifically include the following steps:
s201, obtaining a preset relational mapping table, wherein the relational mapping table records a plurality of theoretical extrusion molding speeds which are sequentially increased progressively according to a set value, and a production speed, an actual extrusion molding speed and a compensation speed which correspond to the theoretical extrusion molding speeds.
S202, judging whether a theoretical extrusion molding speed identical to the theoretical extrusion molding speed to be compensated exists or not by searching the relation mapping table; if yes, go to step S203, otherwise go to step S204.
S203, taking the actual extrusion molding speed corresponding to the theoretical extrusion molding speed which is the same as the theoretical extrusion molding speed to be compensated in the relational mapping table as the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated.
It should be noted that the purpose of adding the need to determine whether the theoretical extrusion molding speed identical to the theoretical extrusion molding speed to be compensated exists in the map is to directly use the actual extrusion molding speed corresponding to the theoretical extrusion molding speed identical to the theoretical extrusion molding speed to be compensated in the map as the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated without calculating again if the theoretical extrusion molding speed to be compensated exists directly in the map. For example, if the theoretical extrusion molding speed to be compensated is 20r/min, the actual extrusion molding speed 19.1r/min corresponding to the theoretical extrusion molding speed 20r/min can be directly used as the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated from table 2, and the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated does not need to be calculated by a compensation calculation formula, so that the waste of calculation resources can be reduced, and the compensation efficiency can be improved.
S204, determining the interval of the theoretical extrusion molding speed to be compensated by searching the relational mapping table, and calculating the actual extrusion molding speed compensated by the theoretical extrusion molding speed to be compensated according to the following compensation calculation formula:
(r2-r1)*(a-b)/c+r1+a；
wherein r1 is the compensation speed that theoretical extrusion molding speed that is less corresponds in the interval of theoretical extrusion molding speed place of waiting to compensate, r2 is the compensation speed that theoretical extrusion molding speed that is great corresponds in the interval of theoretical extrusion molding speed place of waiting to compensate, a is the theoretical extrusion molding speed of waiting to compensate, b is the theoretical extrusion molding speed that is less in the interval of theoretical extrusion molding speed place of waiting to compensate, c is the setting value when theoretical extrusion molding speed increases gradually in proper order in the relational mapping table.
According to the extrusion molding speed compensation method provided by the embodiment of the invention, the actual extrusion molding speed corresponding to any theoretical extrusion molding speed is determined through the pre-established relational mapping table and the compensation calculation formula, the theoretical extrusion molding speed is compensated more reasonably, the problem of speed mutation during compensation can be prevented, the stability of the outer diameter of the optical cable is ensured, and meanwhile, the automation degree and the efficiency are very high because manual participation is not needed.
