Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. It is to be understood that the terms "upper", "lower", "left", "right", "front", "back", "inner", "outer", and the like as used herein, whether or not specifically defined herein, are used in a generic and descriptive sense only and not for purposes of limitation.
Referring to fig. 1 and 2, an embodiment of the present invention discloses an alternating dyeing control method of a dyeing machine, which includes:
s101, the main control 4 controls the sensing part to detect the number of cycle turns of the sensing part in real time;
and S102, controlling the flow driving piece 3 to enter an alternating operation stage when the number of the circulating turns reaches a preset number of turns.
The alternating operation phases comprise a plurality of cycles, in one of which the flow of the flow driver 3 varies as follows:
and S103, controlling the flow driving part 3 to reduce and raise the flow in stages by the main control part 4 according to the cycle number.
The flow driving member 3 may be a variable frequency water pump, a variable frequency fan, or a component such as a valve member capable of changing the flow. During an operating cycle, the flow drive 3 is able to reduce the flow and then to increase the flow back to h, in which process the flow of the flow drive 3 is reduced, so that during an operating cycle the total power of the flow drive 3 is reduced, and the total power consumption is reduced. In the dyeing process of the cloth, although the overall medium circulation flow rate is reduced in one period, because the higher medium circulation flow rate and the lower medium circulation flow rate in the same period act on the cloth alternately, the circulation flow rate of the whole alternating operation stage is still enough to push the circulation of the cloth for a plurality of periods, and the problems of curling, wrinkling and the like cannot be caused.
The embodiment of the invention has the following beneficial effects:
according to the alternating dyeing control method of the dyeing machine, the number of the circulating turns of the cloth in the cylinder body 1 is detected, when the number of the circulating turns reaches the preset number of the turns, the flow driving piece 3 is controlled to enter the alternating operation stage with a plurality of periods, in a single period of the alternating operation stage, the flow driving piece 3 can carry out staged reduction and increase on the flow, and when the flow driving piece 3 reduces the flow, the power consumption of the flow driving piece 3 can be lowered, so that the total power consumption of the dyeing process is integrally reduced, the use cost is reduced, and the purpose of saving energy is achieved.
In addition, the flow driving part 3 can control the variation range and the variation period of the flow according to the type of the cloth, the process stage where the cloth is located and the gram weight of the cloth, and can change the circulation flow of a medium according to different dyeing conditions, so that the dyeing effect of each process stage of each cloth is improved in a targeted manner, the running time of the cloth in a high-injection-force, high-pressure or high-tension state is reduced, the blowing and pulling effect is reduced, the damage to the material is reduced, and the quality of the cloth is improved. In addition, the flow driving member 3 can adjust the flow according to the type and the gram weight of the cloth, so that the flow driving member can be applied to dyeing processes of various cloths and various dyeing machines such as gas-liquid dyeing machines, airflow dyeing machines and the like, and has the advantage of wide application range.
It should be noted that the number of cycles of the sensing element is detected by the sensing element in real time, the preset flow of the flow driving element 3 is H, that is, the flow of the flow driving element 3 when reaching the rated power, the flow H is used for constant flow circulation of cloth in a conventional dyeing machine, and in the embodiment of the present invention, the main control element 4 controls the flow driving element 3 to operate at a flow H, H is less than or equal to H, H is usually less than H for energy saving, for example, H =0.95H. In addition, the flow rate h of the circulation is different for different fabrics and different gram weights of the fabrics. And when the number of the circulating circles is from 0 th circle to nth circle, n is more than or equal to 1, the flow driving piece 3 operates at a flow h, and the flow h is the initial operation flow. In addition, whether to enter the alternating operation stage or not can be manually switched after a program automatically judges according to the cycle number of the sensor.
Referring to fig. 3, the step of controlling the flow driving member 3 to lower and raise the operation flow in stages by the main control member 4 according to the cycle number in one period of the alternating operation phase comprises:
s201, when the number of the circulation circles reaches the nth circle, the flow driving piece 3 enters the alternating operation stage.
The number of cycles of entering the alternating operation stage can be preset according to different material distribution characteristics and process characteristics, and under general conditions, the number of cycles of the first few cycles does not immediately start to enter the alternating operation stage because the signals collected by the induction part need to be confirmed, and the alternating operation stage is entered after the confirmation is finished. The first n turns can thus serve as a buffer for the alternating operating phase, in order to increase the accuracy of the subsequent flow alternation of the flow driver 3.
S202, in a period, controlling the flow driving part 3 to reduce the flow to operate from the nth circle to the nth plus Deltan circle, wherein the reduced flow is h-Deltah;
s203, subsequently controlling the flow driving member 3 to operate in a flow increasing mode at the stage from the n + ring to the n + ring, wherein m is larger than or equal to 1, and the flow after increasing is h.
Wherein, deltan is the number of turns of the flow driving component for reducing the flow, deltan is more than or equal to 1, deltah is the amplitude of the flow driving component for reducing, deltah is less than h, deltam is the number of turns of the flow driving component for increasing the flow, and Deltam is more than or equal to 1. In S202 and S203, the flow driver 3 is operated continuously in the n-th to n +. DELTA.n turns at a flow rate of h-DELTA h, and subsequently in the n + -DELTA.n to n +. DELTA.n +. DELTA.m turns at a flow rate of h, the entire n-th to n +. DELTA.n +. DELTA.m turns forming one of the cycles of the alternating operation phase, and thereafter in the same process phase, the operation is continued in accordance with the cycle, and the cycle can also be interrupted manually or automatically during operation.
The step of controlling the flow driving element 3 to reduce and increase the operation flow by stages by the main control element 4 according to the cycle number further comprises:
s204, when the process stage is a pretreatment stage, controlling the flow driving member 3 to make A1 × Δ n =Δm;
for most of the existing cloth materials, the pretreatment stage or the cloth boiling stage needs more sufficient circulation, and a larger circulation flow needs to be ensured, so that the crease problem can be reduced, therefore, in the pretreatment stage or the cloth boiling stage, the time of low-flow circulation needs to be properly shortened. In the dyeing stage, the cloth is more likely to have the conditions of edge curling and the like, but the sensitivity of the cloth is not high to the problem of edge curling in the pretreatment stage, so that in the dyeing stage, the time of low-flow circulation can be prolonged, and the number of turns delta n of the low-flow circulation is large, so that the energy-saving effect is achieved. In the soaping stage, the cloth finishes the processes of dyeing, color fixation and the like, and the influence of low circulation flow on the cloth is small in the soaping stage, so that the low circulation time can be prolonged, and the number of low circulation turns delta n is large, so that the energy-saving effect is achieved.
Further, referring to fig. 4, the step of the main control 4 controlling the flow driving element 3 to perform staged lowering and raising of the operation flow according to the cycle number further includes:
s301, if the main control 4 detects that the type of the fabric is a first preset type:
s302, when the process stage is a dyeing stage, if the grammage of the fabric is less than a first preset grammage, controlling the flow driving member 3 to make B1 × Δ n =Δm;
s303, when the process stage is a dyeing stage, if the grammage of the fabric is greater than or equal to the first preset grammage, controlling the flow driving member 3 to make B2 × Δ n =Δm;
s304, when the process stage is a soaping stage, if the gram weight of the fabric is less than a second preset gram weight, controlling the flow driving member 3 to make C1 × Δ n =Δm;
s305, when the process stage is a soaping stage, if the grammage of the fabric is greater than or equal to the second preset grammage and less than the third preset grammage, controlling the flow driving member 3 to make C2 × Δ n =Δm;
and S306, when the process stage is a soaping stage, if the gram weight of the cloth is greater than or equal to the third preset gram weight, controlling the flow driving member 3 to enable C3 x Δ n =Δm.
It should be noted that, in this embodiment, the first preset type of cloth is a conventional cloth that is relatively loose and is not prone to crease and edge curl problems, such as eyelet, undershirt, and rib cloth, and in the dyeing stage, the first preset type of cloth is prone to edge curl in the dyeing stage, so that the influence of low flow circulation needs to be reduced in the dyeing stage, and the soaping stage has a small influence on the first preset type of cloth and is not prone to crease or edge curl, so that the period of low flow circulation in the soaping stage can be appropriately prolonged.
More specifically, as the grammage of the cloth increases, the sensitivity of the first preset type of cloth to the generation of curls and creases increases, so when the grammage of the first preset type of cloth is lower than the first preset grammage, the number of low flow cycles can be extended, and therefore B1 can be set to be equal to or less than B2. In the present embodiment, B1=1/2 is set, i.e. 1/2 × Δ n =Δm is controlled, i.e. the number of low flow cycles is 2 times the number of high flow cycles. And when the grammage of the first preset type of cloth is greater than or equal to the first preset grammage, the sensitivity of the first preset type of cloth to the generation of curling and creasing is further increased, and at this time, the number of low-flow circulation turns needs to be reduced, in this embodiment, B2=1 can be selectively set, so that Δ n =Δm, that is, the number of low-flow circulation turns and the number of high-flow circulation turns are equal. In this embodiment, the first preset gram weight can be set to 250 grams per square meter according to the specification characteristics of a first preset type of cloth.
In the soaping stage, although the sensitivity of the first preset type of cloth to the generation of the curled edges and the creases is not high, the sensitivity of the first preset type of cloth to the generation of the curled edges and the creases is still increased along with the increase of the gram weight of the cloth, and in order to ensure the quality, the number of the circulation loops of the first preset type of cloth in the soaping stage can be adjusted as follows according to the specification characteristics of the first preset type of cloth: c1 is more than or equal to C2 is more than or equal to C3. In this embodiment, C1=1/3 is controlled so that 1/3 × Δ n =Δm, i.e., the number of low-flow cycles is 3 times the number of high-flow cycles, when the grammage of the first preset type of cloth is less than or equal to the second preset grammage and less than the third preset grammage, C2=1/2 is controlled so that the variation cycle of the flow driving member 3 satisfies 1/2 × Δ n =Δm, i.e., the number of low-flow cycles is 2 times the number of high-flow cycles, and C3=1 is controlled so that the variation cycle of the flow driving member 3 satisfies Δ n =Δm, when the grammage of the first preset type of cloth is greater than or equal to the third preset grammage. In this embodiment, according to the specification characteristics of a first preset type of fabric, the second preset grammage may be set to 160 grams per square meter and the third preset grammage may be set to 300 grams per square meter.
Referring to fig. 5, the step of the main control 4 controlling the flow driving member 3 to perform staged lowering and raising of the operation flow according to the cycle number further includes:
s401, if the main control 4 detects that the type of the cloth is a second preset type;
s402, when the process stage is a dyeing stage or a soaping stage, controlling the flow driving member 3 to make D1 × Δ n =Δm.
In this embodiment, the second preset type of cloth is a thick, heavy and high water absorption cloth such as terry cloth and flannelette, and since the second preset type of cloth has no high sensitivity to curling or folding in the dyeing stage and the soaping stage, D1 can be set to be a small value for the second preset type of cloth of each specification, in this embodiment, D1=1/2 is set so that the variation cycle of the flow driving member 3 satisfies 1/2 Δ n =Δm, and the number of low-flow cycles is appropriately increased.
Referring to fig. 6, the step of controlling the flow driving element 3 to lower and raise the operation flow in stages by the main control element 4 according to the cycle number further includes:
s501, if the main control 4 detects that the type of the fabric is a third preset type:
s502, when the process stage is the dyeing stage, controlling the flow driver 3 to make B3 × Δ n =Δm;
s503, when the process stage is the soaping stage, controlling the flow driving member 3 to make C4 × Δ n =Δm.
In this embodiment, the third preset type of cloth is a light and thin cloth such as viscose cloth and spandex cloth, which has a smooth cloth surface, low wet cloth strength and is easy to break, and the third preset type of cloth is not sensitive to curling or crease generation in the dyeing stage, so in this embodiment, B3=1/2 may be set, the flow driving member 3 is controlled to make 1/2 Δ n =Δm, and the time of the low flow cycle is appropriately prolonged, whereas the third preset type of cloth is not easy to curl or crease generate in the soaping stage, and therefore the time of the low flow cycle of the third preset type of cloth in the soaping stage needs to be prolonged as much as possible, and B3 may be set to be greater than or equal to C4, in this embodiment, C4=1/3 may be set, and the flow driving member 3 is controlled to make 1/3 Δ n =Δm.
Referring to fig. 7, the step of controlling the flow driving member 3 to lower and raise the operation flow in stages by the main control member 4 according to the number of cycles in one period of the alternating operation phase further includes:
s601, if the main control 4 detects that the type of the fabric is a fourth preset type:
s602, when the process stage is a dyeing stage, controlling the flow driver 3 to make B4=Δn =Δm;
s603, when the process stage is a soaping stage, controlling the flow driving member 3 to make C5 × Δ n =Δm.
In this embodiment, the fourth preset type fabric is a fabric such as plain fabric or woven fabric, which is relatively dense, relatively hard, and easily creased and curled, and the fourth preset type fabric has relatively low elasticity and is easily curled in the dyeing stage, so in the dyeing stage, the number of turns of the low flow rate cycle needs to be controlled, the value of B4 is as large as possible, in this embodiment, B4=1 is set, and Δ n =Δm is controlled by controlling the flow rate driving member 3, and the number of turns of the low flow rate cycle is the same as the number of turns of the high flow rate cycle. In the soaping stage, the sensitivity of the fourth preset type of cloth to curling or crease generation is reduced, for the fourth preset type of cloth with the existing specification, the number of turns of low-flow circulation can be properly prolonged to enable B4 to be larger than or equal to C5, in the embodiment, C5=1/2 can be set, and the flow driving piece 3 is controlled to enable 1/2 < delta > n < delta > m.
Referring to fig. 8, the step of the main control 4 controlling the flow driving member 3 to perform staged lowering and raising of the operation flow according to the cycle number further includes:
s701, if the main control 4 detects that the type of the fabric is a fifth preset type:
s702, when the process stage is the dyeing stage, controlling the flow driver 3 to make B5 × Δ n =Δm;
s703, when the process stage is the soaping stage, controlling the flow driving member 3 to make C6 × Δ n =Δm.
In this embodiment, the fifth preset type of cloth is a very light, smooth and glossy surface, and sensitive to mechanical tension, such as chemical fiber cloth, and the fifth preset type of cloth is similar to the third preset type of cloth, and has low sensitivity to curling or folding in the dyeing stage, and has low sensitivity to curling or folding in the soaping stage, so that B5 is controlled to be greater than or equal to C6. B5=1/2 may be set so that 1/2 × Δ n =Δm in the dyeing stage, and C6=1/3 may be set in the soaping stage, and the flow rate driver 3 may be controlled so that 1/3 × Δ n =Δm. And the flow rate of the flow rate driving member 3 is reduced by a magnitude Δ h which is larger than that of the third preset type cloth.
Referring to fig. 9, the step of the main control 4 controlling the flow driving member 3 to perform staged lowering and raising of the operation flow according to the cycle number further includes:
s801, if the main control 4 detects that the type of the fabric is a sixth preset type:
