Description

Technical Field

[0001] The invention relates to the technical field of dyeing and finishing, and in particular to an alternating dyeing control method of a dyeing machine and a dyeing machine. Background Art

[0002] Existing dyeing machines usually use flow drivers such as water pumps and fans to drive liquid or gas to circulate in the dyeing machine. The liquid or gas can drive the fabric in the dyeing machine to circulate to complete pre-treatment, dyeing, post-treatment and other processes. In the circulation process of traditional dyeing machines, at the same process stage, the water pump / fan operates at a constant speed. In order to meet the requirements of different fabric types and different process flows for the circulation flow, the speed of the water pump / fan is generally set to a larger value. The fabric completes the dyeing process in an environment with a relatively large dye flow rate. During this process, the flow rate is constant. Therefore, during the entire dyeing process, the water pump / fan maintains a high speed for a long time, which consumes a lot of electricity. Under the current situation of energy conservation, emission reduction and double reduction, it is an uneconomical production control method. In addition, during the dyeing process, the industry generally believes that as long as a large flow of circulating medium is used to drive the cloth to circulate, the cloth will have fewer quality problems. However, in actual practice, if the entire dyeing process does not take into account different process stages and different fiber characteristics, and uses the same circulating flow medium to drive the cloth, it is easy to produce quality problems such as curling and wrinkling to varying degrees. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an alternating dyeing control method for a dyeing machine, which can reduce the operating flow of the flow driving component according to the number of circulation circles of the cloth to save electric energy, achieve energy saving and emission reduction, and improve the quality of the cloth, and has a wide applicability.

[0004] In order to solve the above technical problems, the present invention provides an alternating dyeing control method for a dyeing machine, comprising:

[0005] The main control controls the flow driving component to operate so that the flow driving component drives the flowing medium to drive the cloth to circulate.

[0006] The main control detects the number of cycles of the cloth in real time;

[0007] When the number of cycles reaches a preset number of cycles, the flow driving element is controlled to enter an alternating operation stage;

[0008] Among them, the alternating operation stage includes multiple cycles. In one cycle of the alternating operation stage, the main control controls the flow driver to reduce and increase the operating flow in stages according to the number of cycles, so as to reduce the total power of the flow driver in the alternating operation stage.

[0009] As an improvement of the above solution, the steps of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles include:

[0010] The preset flow rate of the flow driving element is H. When the number of cycles is between the 0th and nth cycles, n≥1, the flow driving element operates at the flow rate h.

[0011] When the number of cycles reaches the nth cycle, the flow driving element enters the alternating operation stage;

[0012] In a cycle of the alternating operation stage, when the number of cycles is in the stage from the nth cycle to the n+△nth cycle, the main control controls the flow driver to reduce the flow rate, and the reduced flow rate is h-△h, wherein △n is the number of cycles for the flow driver to reduce the flow rate, △n≥1, and △h is the amplitude of the flow reduction of the flow driver, △h<h.

[0013] Then, in the stage from the n+△nth circle to the n+△n+△mth circle, the flow driving element is controlled to increase the flow rate, and the increased flow rate is h, wherein △m is the number of circles for which the flow driving element increases the flow rate, and △m≥1.

[0014] As an improvement of the above solution, the step of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles further includes:

[0015] When the process stage is the pre-processing stage, the flow driving element is controlled so that A1*△n=△m.

[0016] As an improvement of the above solution, the step of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles further includes:

[0017] If the main control detects that the type of the fabric is the first preset type:

[0018] When the process stage is the dyeing stage, if the gram weight of the fabric is less than the first preset gram weight, the change cycle of the flow driving element is controlled so that B1*△n=△m;

[0019] When the process stage is the dyeing stage, if the grammage of the fabric is greater than or equal to the first preset grammage, the change cycle of the flow driving element is controlled so that B2*△n=△m;

[0020] When the process stage is the soap washing stage, if the gram weight of the fabric is less than the second preset gram weight, the change cycle of the flow driving element is controlled so that C1*△n=△m;

[0021] When the process stage is the soap washing stage, if the grammage of the fabric is greater than or equal to the second preset grammage and less than the third preset grammage, the change cycle of the flow driving element is controlled so that C2*△n=△m;

[0022] When the process stage is the soap washing stage, if the grammage of the cloth is greater than or equal to the third preset grammage, the change cycle of the flow driving element is controlled so that C3*△n=△m.

[0023] As an improvement of the above solution, B1≤B2, C1≤C2≤C3.

[0024] As an improvement of the above solution, the step of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles further includes:

[0025] If the main control detects that the type of the cloth is the second preset type and the process stage is the dyeing stage or the soaping stage, the change cycle of the flow driving element is controlled so that D1*△n=△m.

[0026] As an improvement of the above solution, the step of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles further includes:

[0027] If the main control detects that the type of the fabric is the third preset type:

[0028] When the process stage is the dyeing stage, the change cycle of the flow driving element is controlled so that B3*△n=△m;

[0029] When the process stage is the soap washing stage, the change cycle of the flow driving element is controlled so that C4*△n=△m;

[0030] Among them, B3≥C4.

[0031] As an improvement of the above solution, the step of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles further includes:

[0032] If the main control detects that the type of the fabric is the fourth preset type:

[0033] When the process stage is the dyeing stage, the change cycle of the flow driving element is controlled so that B4*△n=△m;

[0034] When the process stage is the soap washing stage, the change cycle of the flow driving element is controlled so that C5*△n=△m;

[0035] Among them, B4≥C5.

[0036] As an improvement of the above solution, the step of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles further includes:

[0037] If the main control detects that the type of the fabric is the fifth preset type:

[0038] When the process stage is the dyeing stage, the change cycle of the flow driving element is controlled so that B5*△n=△m;

[0039] When the process stage is the soap washing stage, the change cycle of the flow driving element is controlled so that C6*△n=△m;

[0040] Among them, B5≥C6.

[0041] As an improvement of the above solution, the step of the main control controlling the flow driving element to reduce and increase the operating flow in stages according to the number of cycles further includes:

[0042] When the main control detects that the type of the cloth is the sixth preset type and the process stage is the dyeing stage or the soaping stage, the change cycle of the flow driving element is controlled so that D2*△n=△m.

[0043] The present invention also provides a dyeing machine, comprising a cylinder body, a nozzle, a flow driving component and a main control component capable of implementing the alternating dyeing control method of the dyeing machine as described above, wherein the nozzle is connected to the inside of the cylinder body, the flow driving component is connected to the nozzle through a pipe, the flow driving component can drive the flowing medium to spray from the nozzle into the cylinder body, the flowing medium can drive the cloth to circulate in the cylinder body, a sensor component is fixed on the cloth, an induction component is provided on the cylinder body, and the induction component is electrically connected to the main control component.

[0044] The implementation of the present invention has the following beneficial effects:

[0045] The alternating dyeing control method of the dyeing machine of the present invention first detects the number of circulations of the cloth in the cylinder body. When the number of circulations reaches a preset number, the flow driving component is controlled to enter an alternating operation stage of multiple cycles. In a single cycle of the alternating operation stage, the flow driving component will reduce and increase the flow in stages. When the flow driving component reduces the flow, the rotation speed of the flow driving component is reduced, thereby reducing the power consumption, thereby reducing the total power consumption of the dyeing process as a whole, reducing the use cost, and achieving the purpose of saving energy.

[0046] In addition, the flow driver will control the amplitude and cycle of the flow change according to the type of fabric, the process stage and the grammage of the fabric, and can change the circulation flow of the medium according to different dyeing conditions, thereby improving the dyeing effect of each fabric at each process stage in a targeted manner, and reducing the running time of the fabric under high jet force, high pressure or high tension, reducing the blowing and pulling effect, and reducing damage to the material, thereby improving the quality of the fabric.

[0047] Furthermore, since the flow driver can adjust the flow according to the type and weight of the fabric, it can be applied to the dyeing process of various fabrics and various types of dyeing machines such as gas-liquid dyeing machines, airflow dyeing machines, etc., and has the advantage of a wide range of applications.

[0058] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0059] See also Figure 1 and Figure 2 The embodiment of the present invention discloses an alternating dyeing control method of a dyeing machine. In order to achieve energy saving effect, the alternating dyeing control method of the dyeing machine includes:

[0060] S101, the main control unit 4 controls the sensing element to detect the number of cycles of the sensing element in real time;

[0061] S102, when the number of cycles reaches a preset number of cycles, the flow driving element 3 is controlled to enter an alternating operation stage.

[0062] The alternating operation stage includes a plurality of cycles. In one cycle of the alternating operation stage, the flow rate of the flow driving member 3 changes as follows:

[0063] S103, the main control 4 controls the flow driving component 3 to reduce and increase the flow in stages according to the number of cycles.

[0064] The flow drive 3 can be a variable frequency water pump, a variable frequency fan, or a valve component that can change the flow rate. In one operation cycle, the flow drive 3 can reduce the flow rate and then let the flow rate rise back to h. In this process, the flow rate of the flow drive 3 will decrease. Therefore, in one operation cycle, the total power of the flow drive 3 will decrease, thereby reducing the total power consumption. For the dyeing process of the cloth, although the overall medium circulation flow rate is reduced in one cycle, since a higher medium circulation flow rate and a lower medium circulation flow rate act on the cloth alternately in the same cycle, for multiple cycles, the circulation flow rate of the entire alternating operation stage is still sufficient to promote the circulation of the cloth, and will not cause curling, wrinkling and other problems.

[0065] The beneficial effects of the embodiments of the present invention are as follows:

[0066] The alternating dyeing control method of the dyeing machine in the embodiment of the present invention first detects the number of circulations of the cloth in the cylinder 1. When the number of circulations reaches a preset number, the flow driving component 3 is controlled to enter an alternating operation stage of multiple cycles. Within a single cycle of the alternating operation stage, the flow driving component 3 will reduce and increase the flow in stages. When the flow driving component 3 reduces the flow, the power consumption of the flow driving component 3 will become lower, thereby reducing the total power consumption of the dyeing process as a whole, reducing the use cost, and achieving the purpose of saving energy.

[0067] In addition, the flow driver 3 controls the change amplitude and change cycle of the flow according to the type of the fabric, the process stage and the gram weight of the fabric, and can change the circulation flow of the medium according to different dyeing conditions, which not only improves the dyeing effect of each process stage of each fabric in a targeted manner, but also reduces the running time of the fabric under high injection force, high pressure or high tension, reduces the blowing and pulling effect, reduces the damage to the material, and thus improves the quality of the fabric. In addition, since the flow driver 3 adjusts the flow according to the type and gram weight of the fabric, it can be applied to the dyeing process of various fabrics and various types of dyeing machines such as gas-liquid dyeing machines, airflow dyeing machines, etc., and has the advantage of a wide range of applications.

[0068] It should be noted that the number of cycles of the sensor is detected in real time by the sensor, and the preset flow rate of the flow driver 3 is H, that is, the flow rate when the flow driver 3 reaches the rated power. The traditional dyeing machine uses the flow rate H to circulate the fabric at a constant flow rate. In the embodiment of the present invention, the main control 4 controls the flow driver 3 to operate at a flow rate h, h≤H. In order to save energy, h is usually less than H, such as h=0.95H. In addition, for different fabrics and different gram weights of the fabrics, the circulating flow rate h is different. When the number of cycles is from the 0th to the nth, n≥1, and the flow driver 3 operates at a flow rate h, which is the initial operating flow rate. In addition, whether to enter the alternating operation stage, in addition to the program automatically judging according to the number of cycles of the sensor, a manual switch can also be performed.

[0069] See also Figure 3 , in one cycle of the alternating operation stage, the main control 4 controls the flow driving component 3 to reduce and increase the operating flow in stages according to the number of cycles, including:

[0070] S201, when the number of cycles reaches the nth cycle, the flow driving element 3 enters the alternating operation stage.

[0071] The number of cycles to enter the alternating operation stage can be preset according to different fabric characteristics and process characteristics. In general, the number of cycles will not immediately start to enter the alternating operation stage in the first few cycles, because the signal collected by the sensing element needs to be confirmed. After confirmation, the alternating operation stage is entered. Therefore, the first n cycles can be used as a buffer for the alternating operation stage to improve the accuracy of the subsequent flow alternation of the flow driving element 3.

[0072] S202, in a cycle, in the stage from the nth circle to the n+△nth circle, controlling the flow driving element 3 to reduce the flow rate, and the reduced flow rate is h-△h;

[0073] S203, then in the stage from the n+△nth circle to the n+△n+△mth circle, m≥1, control the flow driving element 3 to increase the flow rate, and the increased flow rate is h.

[0074] Wherein, △n is the number of turns of the flow driver to reduce the flow rate, △n≥1, △h is the amplitude of the flow rate reduction of the flow driver, △h<h, △m is the number of turns of the flow driver to increase the flow rate, △m≥1. In S202 and S203, the flow driver 3 first continuously operates at a flow rate of h-△h in the nth to n+△nth turns, and then continuously operates at a flow rate of h in the n+△nth to n+△n+△mth turns. The entire nth to n+△n+△mth turns form one of the cycles of the alternating operation stage. Thereafter, in the same process stage, the operation will continue according to the cycle. During the operation, the cycle can also be manually or automatically interrupted.

[0075] The step of the main control 4 controlling the flow driving element 3 to reduce and increase the operating flow in stages according to the number of cycles also includes:

[0076] S204, when the process stage is the pre-processing stage, controlling the flow driving element 3 so that A1*△n=△m;

[0077] For most existing fabrics, the pre-treatment stage or the cloth-boiling stage requires more sufficient circulation and a larger circulation flow rate, which can reduce the occurrence of crease problems. Therefore, in the pre-treatment stage or the cloth-boiling stage, the low-flow circulation time needs to be appropriately shortened. In this embodiment, the number of high-flow circulation △m and the number of low-flow circulation △n are equal. After experimental verification, when △n=△m, that is, the cycle of the high-flow circulation is roughly equal to the cycle of the low-flow circulation, it can ensure that the occurrence of crease problems is reduced while achieving a better energy-saving effect. In the dyeing stage, the fabric is more likely to have curling, but its sensitivity is not as high as the sensitivity of the curling problem in the pre-treatment stage. Therefore, in the dyeing stage, the low-flow circulation time can be extended, and the number of low-flow circulation △n is large to achieve energy-saving effects. In the soap washing stage, the fabric has completed dyeing, color fixing and other processes. At this stage, the fabric is less affected by the low circulation flow rate. Therefore, in this stage, the low-flow circulation time can also be extended, and the number of low-flow circulation △n is large to achieve energy-saving effects.

[0078] Further, see Figure 4 The main control 4 controls the flow driver 3 to reduce and increase the running flow in stages according to the number of cycles, and the step also includes:

[0079] S301, if the main control 4 detects that the type of the fabric is the first preset type:

[0080] S302, when the process stage is the dyeing stage, if the gram weight of the cloth is less than the first preset gram weight, control the flow driving element 3 so that B1*△n=△m;

[0081] S303, when the process stage is the dyeing stage, if the grammage of the cloth is greater than or equal to the first preset grammage, controlling the flow driving element 3 so that B2*△n=△m;

[0082] S304, when the process stage is the soap washing stage, if the gram weight of the cloth is less than the second preset gram weight, controlling the flow driving element 3 so that C1*△n=△m;

[0083] S305, when the process stage is the soap washing stage, if the grammage of the cloth is greater than or equal to the second preset grammage and less than the third preset grammage, control the flow driving element 3 so that C2*△n=△m;

[0084] S306, when the process stage is the soap washing stage, if the grammage of the cloth is greater than or equal to the third preset grammage, control the flow driving element 3 so that C3*△n=△m.

[0085] It should be noted that, in the present embodiment, the first preset type of fabric is conventional fabric such as mesh fabric, jersey fabric and rib fabric, which is relatively loose and not prone to creases or curling. During the dyeing stage, the first preset type of fabric is prone to curling. Therefore, it is necessary to reduce the impact of low-flow circulation during the dyeing stage. The soap washing stage has less impact on the first preset type of fabric, and it is not easy to produce creases or curling. Therefore, the period of low-flow circulation in the soap washing stage can be appropriately extended.

[0086] More specifically, as the weight of the fabric increases, the sensitivity of the first preset type of fabric to curling and creases increases. Therefore, when the weight of the first preset type of fabric is lower than the first preset weight, the number of low-flow cycles can be extended. Therefore, B1≤B2 can be set. In this embodiment, B1=1 / 2 is set, that is, 1 / 2*△n=△m is controlled, that is, the number of low-flow cycles is twice the number of high-flow cycles. When the weight of the first preset type of fabric is greater than or equal to the first preset weight, the sensitivity of the first preset type of fabric to curling and creases further increases. At this time, the number of low-flow cycles needs to be reduced. In this embodiment, B2=1 can be set to make △n=△m, that is, the number of low-flow cycles is equal to the number of high-flow cycles. In this embodiment, according to the specification characteristics of the first preset type of fabric, the first preset weight can be set to 250g / ㎡.

[0087] During the soap washing stage, although the first preset type of fabric is not very sensitive to curling and creases, as the weight of the fabric increases, the sensitivity of the first preset type of fabric to curling and creases will still increase. In order to ensure the quality, the number of cycles of the first preset type of fabric in the soap washing stage can be adjusted as follows according to the specification characteristics of the first preset type of fabric: C1≤C2≤C3. In this embodiment, when the gram weight of the first preset type of fabric is less than the second preset gram weight, C1=1 / 3 is controlled so that 1 / 3*△n=△m, that is, the number of low flow cycles is 3 times the number of high flow cycles, when the gram weight of the first preset type of fabric is less than or equal to the second preset gram weight and less than the third preset gram weight, C2=1 / 2 is controlled so that the change cycle of the flow drive 3 satisfies 1 / 2*△n=△m, that is, the number of low flow cycles is 2 times the number of high flow cycles, when the gram weight of the first preset type of fabric is greater than or equal to the third preset gram weight, C3=1 is controlled so that the change cycle of the flow drive 3 satisfies △n=△m. In this embodiment, according to the specification characteristics of the first preset type of fabric, the second preset gram weight can be set to 160g / ㎡ and the third preset gram weight can be set to 300g / ㎡.

[0088] See also Figure 5The main control 4 controls the flow driver 3 to reduce and increase the running flow in stages according to the number of cycles, and the step also includes:

[0089] S401, if the main control 4 detects that the type of the fabric is a second preset type;

[0090] S402, when the process stage is the dyeing stage or the soap washing stage, the flow driving element 3 is controlled so that D1*△n=△m.

[0091] In this embodiment, the second preset type of fabric is thicker, heavier and more absorbent fabric such as terry cloth and flannel. Since the second preset type of fabric is not very sensitive to curling or creases during the dyeing and soaping stages, D1 can be set to a smaller value for the second preset type of fabrics of various existing specifications. In this embodiment, D1 is set to 1 / 2 so that the change period of the flow drive element 3 satisfies 1 / 2*△n=△m, and the number of low flow cycles is appropriately increased.

[0092] See also Figure 6 The main control 4 controls the flow driver 3 to reduce and increase the running flow in stages according to the number of cycles, and the step also includes:

[0093] S501: If the main control 4 detects that the type of the fabric is the third preset type:

[0094] S502, when the process stage is the dyeing stage, controlling the flow driving element 3 so that B3*△n=△m;

[0095] S503, when the process stage is the soap washing stage, control the flow driving element 3 so that C4*Δn=Δm.

[0096] In this embodiment, the third preset type of fabric is viscose fiber fabric and spandex fabric, which are relatively light, smooth, have low wet strength, and are easy to break. The third preset type of fabric is not very sensitive to curling or creases during the dyeing stage. Therefore, in this embodiment, B3=1 / 2 can be set, and the flow driver 3 is controlled so that 1 / 2*△n=△m, and the low flow cycle time is appropriately extended. The third preset type of fabric is not prone to curling or creases during the soaping stage. Therefore, it is necessary to extend the low flow cycle time of the third preset type of fabric during the soaping stage as much as possible, and B3≥C4 can be set. In this embodiment, C4=1 / 3 can be set, and the flow driver 3 is controlled so that 1 / 3*△n=△m.

[0097] See also Figure 7, in one cycle of the alternating operation stage, the main control 4 controls the flow driving component 3 to reduce and increase the operating flow in stages according to the number of cycles, and the step also includes:

[0098] S601: If the main control 4 detects that the type of the fabric is the fourth preset type:

[0099] S602, when the process stage is the dyeing stage, controlling the flow driving element 3 so that B4*△n=△m;

[0100] S603, when the process stage is the soap washing stage, control the flow driving element 3 so that C5*Δn=Δm.

[0101] In this embodiment, the fourth preset type of fabric is a fabric with a high density, hardness, and easy creases and curling, such as plain fabric and woven fabric. The fourth preset type of fabric has low elasticity and is easy to curl during the dyeing stage. Therefore, in the dyeing stage, it is necessary to control the number of low flow cycles, and the B4 value is as large as possible. In this embodiment, B4=1 is set, and the flow drive 3 is controlled so that △n=△m, and the number of low flow cycles is the same as the number of high flow cycles. In the soaping stage, the sensitivity of the fourth preset type of fabric to curling or creases is reduced. For the fourth preset type of fabric of existing specifications, the number of low flow cycles can be appropriately extended to make B4≥C5. In this embodiment, C5=1 / 2 can be set, and the flow drive 3 can be controlled so that 1 / 2*△n=△m.

[0102] See also Figure 8 The main control 4 controls the flow driver 3 to reduce and increase the running flow in stages according to the number of cycles, and the step also includes:

[0103] S701: If the main control 4 detects that the type of the fabric is the fifth preset type:

[0104] S702, when the process stage is the dyeing stage, controlling the flow driving element 3 so that B5*△n=△m;

[0105] S703, when the process stage is the soap washing stage, control the flow driving element 3 so that C6*Δn=Δm.

[0106] In this embodiment, the fifth preset type of fabric is a very light, smooth and shiny fabric such as chemical fiber fabric, which is sensitive to the tension of the machine. The fifth preset type of fabric is similar to the third preset type of fabric, and is not very sensitive to curling or creases in the dyeing stage, but is less sensitive to curling or creases in the soaping stage, so B5 ≥ C6 is controlled. In the dyeing stage, B5 = 1 / 2 can be set to make 1 / 2*△n = △m, and in the soaping stage, C6 = 1 / 3 can be set to control the flow drive 3 to make 1 / 3*△n = △m. In terms of the flow reduction amplitude △h of the flow drive 3, the amplitude reduced by the third preset type of fabric is greater than that of the fifth preset type of fabric.

[0107] See also Fig. 9 The main control 4 controls the flow driver 3 to reduce and increase the running flow in stages according to the number of cycles, and the steps also include:

[0108] S801: If the main control 4 detects that the type of the fabric is the sixth preset type:

[0109] S802, when the process stage is the dyeing stage or the soap washing stage, the flow driving element 3 is controlled so that D2*△n=△m.

[0110] In this embodiment, the sixth preset type of fabric is an air layer fabric similar to a hollow sponge, which is thicker, has a very high water absorption rate, and is very heavy when wet. The sixth preset type of fabric has large internal gaps and is prone to creases. In order to avoid quality problems such as creases, the D2 value is relatively large.
