Description

Technical Field

[0001] This application belongs to the technical field of fabric dyeing, and particularly relates to a water-saving dyeing machine for textile fabrics and a control method thereof. Background Art

[0002] When using this liquid flow fabric treatment device to dye a fabric, first, a treatment solution is prepared by adding dyes and the like to water to dye the fabric. In addition, after dyeing the fabric with dyes, a washing operation is performed with a cleaning solution to remove the treatment liquid remaining on the fabric from the fabric.

[0003] In the washing operation of the liquid flow type fabric treatment equipment, the treatment liquid in the equipment can be repeatedly discharged and unused washing liquid can be supplied. Specifically, after discharging a certain amount of the treatment liquid in the device, unused cleaning liquid is supplied and the fabric is circulated for a certain time, and the remaining treatment liquid in the fabric is mixed with the supplied unused cleaning liquid to obtain the treatment liquid remaining in the fabric. After diluting the remaining treatment liquid, a certain amount of the treatment liquid in the device is discharged again, and this process is repeated for cleaning.

[0004] However, the water absorption of the fabric itself hinders the discharge of the treatment liquid, resulting in a decrease in the discharge efficiency of the treatment liquid, requiring a large amount of new cleaning liquid, and it is necessary to repeatedly supply new cleaning liquid to improve this. Summary of the Invention

[0005] The purpose of this application is to provide a water-saving dyeing machine for textile fabrics and a control method thereof, which can reduce the water consumption for cleaning the residual dye solution on the fabric after fabric dyeing in view of the above existing technical problems.

[0006] This application provides a water-saving dyeing machine for textile fabrics, including:

[0007] A dyeing machine main body, which includes a first cylinder body and a second cylinder body connected in a V shape;

[0008] A connecting pipe, connected between the ends of the first cylinder body and the second cylinder body that are far away from each other, and the connecting pipe includes a main pipe portion with a height lower than that of the dyeing machine main body;

[0009] A driving roller, installed in the first cylinder body, and the driving roller is connected to a power device;

[0010] An extrusion mechanism, installed in the first cylinder body, and the extrusion mechanism includes a first roller body and a second roller body, and flanges are provided at both ends of the second roller body;

[0011] Among them, the first roller is movably connected to the first cylinder body, and the axis of the first roller is relatively fixed to the first cylinder body. The axis of the second roller can move relative to the first cylinder body. When the fabric is dyed with the dye liquor, the first roller and the second roller are separated and opened from each other. When the fabric is cleaned with the cleaning liquid, the first roller and the second roller are close to each other and closed.

[0012] The first cylinder body and the second cylinder body are integrally connected, and their connection position is lower than the other ends of the corresponding first cylinder body and the second cylinder body. The fabric is placed in the dyeing machine main body for dyeing and cleaning. The connecting pipe is connected between the ends of the first cylinder body and the second cylinder body that are far away from each other. Driven by the driving roller arranged in the dyeing machine main body, the fabric in the dyeing machine main body can move in a cycle, improving the efficiency of fabric dyeing and cleaning. The dye liquor and the cleaning water can be respectively introduced and discharged in the dyeing machine main body. When the fabric is being cleaned, the residual liquid on the fabric is extruded by the extrusion mechanism. The first roller and the second roller are distributed on both sides of the fabric, and the extrusion is realized by controlling the first roller and the second roller to approach each other. When the fabric is being dyed, the first roller and the second roller are in a state of being separated from each other. The second roller provides support for the fabric, and the second roller can be driven to rotate by the motor, facilitating the uniform conveyance of the fabric into the first cylinder body.

[0013] Furthermore, the dyeing machine main body includes:

[0014] A driving mechanism for driving the relative movement between the axis of the second roller and the first cylinder body. The driving mechanism includes a first driving cylinder and an adjusting mechanism;

[0015] Among them, the adjusting mechanism can be adjusted according to the thickness of the extruded fabric, and the adjusting mechanism is connected to the output shaft of the first driving cylinder.

[0016] The relative movement of the first roller and the first cylinder body is driven by the driving mechanism. The first driving cylinder is driven by air pressure, hydraulic pressure or electricity. The driving and adjusting of the adjusting mechanism are realized through the first driving cylinder. When the fabric is placed in the dyeing machine main body, it moves in a rope-like shape, and its thickness is not uniform. The adjusting mechanism can be adaptively adjusted according to the overall thickness of the fabric, realizing the stable extrusion of the residual treatment liquid in the fabric.

[0017] Furthermore, the driving mechanism further includes:

[0018] A first arm part, connected to the adjusting mechanism;

[0019] A second arm part, connected to the second roller;

[0020] A connecting shaft, connected between the first arm part and the second arm part, and the connecting shaft is hinged to the first cylinder body.

[0021] The first arm, the connecting shaft, and the second arm are integrally connected in sequence to control the movement of the second roller when driven by the first driving cylinder. The motor for driving the second roller is installed on the second arm. The second roller is movably connected to the second arm, and the second arm can rotate around its own axis.

[0022] Furthermore, the adjusting mechanism includes:

[0023] An adjusting seat, connected to the first driving cylinder;

[0024] A movable seat, placed inside the adjusting seat and capable of moving along the axis of the adjusting seat;

[0025] An adjusting plate, placed inside the movable seat and capable of moving along the axis of the adjusting seat. The adjusting plate extends outward from the movable seat and is connected to the first arm;

[0026] A first elastic member, placed on both sides of the adjusting plate and abutted against the movable seat;

[0027] A pressure sensor, placed inside the adjusting seat and corresponding to both sides of the movable seat;

[0028] Wherein, the adjusting seat is provided with a first sliding groove corresponding to and cooperating with the adjusting plate, and the movable seat is provided with a second sliding groove corresponding to and cooperating with the adjusting plate.

[0029] The adjusting seat is fixedly connected to the output shaft of the first driving cylinder. The movable seat moves inside the adjusting seat. The pressure sensor can abut against the movable seat. At most, two pressure sensors can detect one pressure value. The pressure sensor is used to judge whether the second roller and the first roller are in an open or closed state. The adjusting plate is movably connected to the movable seat. The first elastic member is placed on both sides of the adjusting plate. When the thickness of the fabric placed between the first roller and the second roller changes continuously, the action of the first elastic member on the adjusting plate is that the distance between the first roller and the second roller is adjusted according to the thickness of the fabric, so as to always keep the extrusion of the first roller and the second roller on the fabric at an appropriate force, facilitating the fabric to pass smoothly between the first roller and the second roller. The first elastic member adopts a spring, etc.

[0030] Furthermore, the driving mechanism is provided with a positioning mechanism, and the positioning mechanism includes:

[0031] A rotating seat, installed on the outside of the first cylinder body and capable of rotating around the axis of the connecting shaft;

[0032] A telescopic column, installed on the rotating seat and capable of telescopic movement;

[0033] A second elastic member, placed between the telescopic column and the rotating seat;

[0034] A roller, installed on the telescopic column;

[0035] Wherein, the connecting shaft is provided with an annular groove that abuts against the roller, and the annular groove is provided with a positioning groove.

[0036] When the sizes of the dyed fabrics are different, the distances between the first roller and the second roller for extruding the residual liquid are also different, and can be adjusted through the positioning mechanism. The rotating seat can be rotationally adjusted, and its position is mainly preset according to the fabric. After the telescopic column on the rotating seat is adjusted, the connecting shaft is controlled by the first driving cylinder to rotate so that the positioning groove corresponds to the telescopic column, and the telescopic column mainly moves in the positioning groove. The second elastic member is a spring or the like, and acts on the telescopic column through the second elastic member and moves towards the connecting shaft direction, so that the roller abuts against the annular groove and the positioning groove, improving the stability when the telescopic column moves.

[0037] Further, the positioning groove includes:

[0038] A gentle slope, placed in the path of the roller in the annular groove and on one side of the positioning groove;

[0039] A steep slope, placed in the path of the roller in the annular groove and on the other side of the positioning groove.

[0040] When the roller moves towards the gentle slope direction, the first roller and the second roller move away from each other correspondingly. Through the gentle slope, the resistance received when the rollers approach each other is small, enabling quick adjustment when the thickness of the fabric strand suddenly increases, ensuring the smoothness of the fabric passing through the first roller and the second roller. When the roller moves towards the steep slope direction, the first roller and the second roller move closer to each other correspondingly. When the thickness of the fabric strand becomes smaller, the first roller and the second roller can quickly approach, maintaining a relatively stable squeezing effect on the fabric.

[0041] Further, the positioning mechanism further includes:

[0042] A first bevel gear, installed on the rotating seat;

[0043] A second bevel gear, meshing with the first bevel gear and connected to the output shaft of the motor.

[0044] The second bevel gear is connected to the motor. Through the mutual meshing between the first bevel gear and the second bevel gear, the adjustment of the rotating seat is convenient, stable, and has a high precision.

[0045] This application also provides a control method for a water-saving dyeing machine for textile fabrics. The specific steps include:

[0046] S1, when the fabric is in the dyeing step of the dyeing machine main body, the first roller and the second roller are controlled by the driving mechanism to separate and open;

[0047] S2. When the fabric is in the cleaning step of the dyeing machine main body, determine data such as the fabric size and thickness, adjust the adjustment and positioning mechanism to a preset position, control the first roller and the second roller to approach and close through the driving mechanism, and move the telescopic column into the positioning groove.

[0048] By setting the separation and approach of the first roller and the second roller to control the direct passage or extrusion of the fabric to squeeze out the residual liquid pressure, the cleaning efficiency of the fabric is improved and the water consumption is saved.

[0049] The beneficial effects of this application are:

[0050] 1. When the fabric is being cleaned, the residual liquid on the fabric is squeezed out by the extrusion mechanism, accelerating the cleaning efficiency and saving water.

[0051] 2. Through the adjustment mechanism, it can be adaptively adjusted according to the overall thickness of the fabric to stably extrude the residual treatment liquid in the fabric.

[0052] 3. The pressure sensor is used to judge whether the second roller and the first roller are in the open or closed state.

[0053] 4. Through the action of the first elastic member on the adjusting plate, the distance between the first roller and the second roller is adjusted according to the thickness of the fabric, and the extrusion of the first roller and the second roller on the fabric always maintains an appropriate force, facilitating the fabric to smoothly pass between the first roller and the second roller and realizing the extrusion of the residual liquid.

The dyeing solution and the cleaning water can be respectively introduced and discharged in the dyeing machine main body 100. When the fabric is being cleaned, the residual liquid on the fabric is extruded by the extrusion mechanism 400. The first roller body 410 and the second roller body 420 are distributed on both sides of the fabric, and extrusion is achieved by controlling the first roller body 410 and the second roller body 420 to approach each other. When the fabric is being dyed, the first roller body 410 and the second roller body 420 are in a separated state, and the second roller body 420 provides support for the fabric. The second roller body 420 can be driven by a motor to rotate, facilitating the uniform conveyance of the fabric into the first cylinder 110.

[0070] Embodiment 2:

[0071] As Figure 1 、 Figure 3 shown, the embodiment of the present application provides a water-saving dyeing machine for textile fabrics. In addition to including the above technical features, further, the dyeing machine main body 100 includes:

[0073] Wherein, the adjusting mechanism 520 can be adjusted according to the thickness of the extruded fabric, and the adjusting mechanism 520 is connected to the output shaft of the first driving cylinder 510.

[0074] By driving the relative movement between the first roller body 410 and the first cylinder body 110 through the driving mechanism 500, the first driving cylinder 510 is driven by air pressure, hydraulic pressure or electricity. By driving the first driving cylinder 510, the adjusting mechanism 520 is driven to move and adjust. When the fabric is placed in the dyeing machine main body 100, it moves in a strand shape, and its thickness is not uniform. Through the adjusting mechanism 520, it can be adaptively adjusted according to the overall thickness of the fabric, so as to stably extrude the residual treatment liquid in the fabric.

[0082] An adjusting seat 521, which is connected to the first driving cylinder 510;

[0083] A movable seat 522, which is placed in the adjusting seat 521 and can move along the axis of the adjusting seat 521;

[0084] The adjusting plate 523 is placed inside the movable seat 522 and can move along the axis of the adjusting seat 521. The adjusting plate 523 extends outward from inside the movable seat 522 and is connected to the first arm 530.

[0085] The first elastic member 524 is placed on both sides of the adjusting plate 523 and abuts against the movable seat 522.

[0086] The pressure sensor 525 is placed inside the adjusting seat 521 and corresponds to both sides of the movable seat 522.

[0087] Wherein, the adjusting seat 521 is provided with a first sliding groove 526 corresponding to and cooperating with the adjusting plate 523, and the movable seat 522 is provided with a second sliding groove 527 corresponding to and cooperating with the adjusting plate 523.

The first elastic member 524 is placed on both sides of the adjusting plate 523. When the thickness of the fabric placed between the first roller 410 and the second roller 420 changes continuously, the action of the first elastic member 524 on the adjusting plate 523 is that the distance between the first roller 410 and the second roller 420 is adjusted according to the thickness of the fabric, and the extrusion of the first roller 410 and the second roller 420 on the fabric always maintains an appropriate force, facilitating the fabric to pass through between the first roller 410 and the second roller 420 smoothly. The first elastic member 524 adopts a spring or the like.

[0089] Embodiment 4:

[0090] As Figure 3 、 Figure 4 shown, the embodiment of the present application provides a water-saving dyeing machine for textile fabrics. In addition to including the above technical features, further, the driving mechanism 500 is provided with a positioning mechanism 600, and the positioning mechanism 600 includes:

[0091] The rotating seat 610 is installed on the outer side of the first cylinder 110 and can rotate around the axis of the connecting shaft 550.

[0092] The telescopic column 620 is installed on the rotating seat 610 in a telescopic manner.

[0093] The second elastic member 630 is placed between the telescopic column 620 and the rotating seat 610.

[0094] The roller 640 is installed on the telescopic column 620.

[0095] Among them, the connecting shaft 550 is provided with an annular groove 551 that abuts against the roller 640, and the annular groove 551 is provided with a positioning groove 552.

[0096] When the sizes of the dyed fabrics are different, the distances between the first roller body 410 and the second roller body 420 for extruding the residual liquid are also different, and can be adjusted by the positioning mechanism 600. The rotating seat 610 can be rotationally adjusted, and its position is mainly preset according to the fabric. After the telescopic column 620 on the rotating seat 610 is adjusted, the connecting shaft 550 is controlled by the first driving cylinder 510 to rotate so that the positioning groove 552 corresponds to the telescopic column 620, and the telescopic column 620 mainly moves in the positioning groove 552. The second elastic member 630 is a spring or the like. Through the action of the second elastic member 630 on the telescopic column 620 and moving it in the direction of the connecting shaft 550, the roller 640 abuts against the annular groove 551 and the positioning groove 552, improving the stability of the telescopic column 620 during movement.

[0097] Furthermore, the positioning groove 552 includes:

[0098] A gentle slope 553, placed in the path of the roller 640 in the annular groove 551 and on one side of the positioning groove 552;

[0100] When the roller 640 moves towards the gentle slope 553, the first roller body 410 and the second roller body 420 move away from each other correspondingly. Through the gentle slope 553, the resistance received when the rolling path approaches is smaller, enabling faster adjustment when the thickness of the fabric strand suddenly increases, ensuring the smoothness of the fabric passing through the first roller body 410 and the second roller body 420. When the roller 640 moves towards the steep slope 554, the first roller body 410 and the second roller body 420 move closer to each other correspondingly. When the thickness of the fabric strand becomes smaller, the first roller body 410 and the second roller body 420 can quickly approach, maintaining a relatively stable squeezing effect on the fabric.

[0101] Furthermore, the positioning mechanism 600 further includes:

[0102] A first bevel gear 650, installed on the rotating seat 610;

[0103] A second bevel gear 660, meshing with the first bevel gear 650 and connected to the output shaft of the motor.

[0104] The second bevel gear 660 is connected to the motor. Through the mutual meshing between the first bevel gear 650 and the second bevel gear 660, the adjustment of the rotating seat 610 is convenient, stable, and has a high precision.

[0105] Example 5:

[0106] The present application also provides a control method for a water-saving dyeing machine for textile fabrics. The specific steps include:

[0107] S1. When the fabric is in the dyeing step of the dyeing machine main body 100, the first roller 410 and the second roller 420 are controlled by the driving mechanism 500 to separate and open.

[0108] S2. When the fabric is in the cleaning step of the dyeing machine main body 100, data such as the fabric size and thickness are determined, the adjustment and positioning mechanism 600 is adjusted to a preset position, the first roller 410 and the second roller 420 are controlled by the driving mechanism 500 to approach and close, and the telescopic column 620 is moved into the positioning groove 552.

[0109] By setting the separation and approach of the first roller 410 and the second roller 420 to control the direct passage or extrusion of the fabric to squeeze out the residual hydraulic pressure, the cleaning efficiency of the fabric is improved and the water consumption is saved.

[0110] It should be noted that in this article, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including that element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved.
