Description

Technical Field

[0001] This invention relates to the field of fabric dyeing technology, and more specifically, to a fabric dyeing system and dyeing method. Background Technology

[0002] Currently, yarn is woven into greige fabric using weaving equipment. This greige fabric undergoes desizing, sizing, bleaching, mercerizing, dyeing, and finishing processes to become finished fabric. Dyeing refers to the method of coloring fabric fibers with dyes. The existing dyeing process is relatively simple: the treated greige fabric is placed in a dye vat for a certain period of time, then removed and dried before finishing. However, in current technology, the greige fabric is directly removed from the dye vat for drying, resulting in a high moisture content and excess dye. This direct drying leads to a longer drying time, and the excess dye can cause some areas of the fabric to be too dark during drying, affecting the overall dyeing effect. Therefore, improvements are needed. Summary of the Invention

[0003] The purpose of this invention is to provide a fabric dyeing system and dyeing method to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A fabric dyeing system includes a box with an internal cavity. The cavity is provided with a partition for sequentially dividing the cavity into a dyeing cavity, a washing cavity, and a dewatering cavity. The dyeing cavity is used for dyeing the fabric. The washing cavity is provided with a washing mechanism for promoting the washing of the fabric. The dewatering cavity is provided with a dewatering mechanism for squeezing water from the fabric.

[0006] The washing mechanism includes a tensioning component for tensioning the fabric in the washing chamber and a beating component for beating the fabric. The tensioning component includes a tensioning roller that can be raised and lowered for tensioning the fabric, and the beating component includes beating rods arranged opposite to each other. A driving component is also provided in the washing chamber. When the driving component drives the tensioning roller to move upward to release the tension on the fabric, it drives the beating rods to swing relative to each other to beat the fabric.

[0007] The dewatering mechanism includes dewatering rollers arranged opposite each other. The dewatering roller located below the fabric is rotatably arranged, and the dewatering roller located above the fabric is provided with a drainage component for draining the water accumulated on the fabric.

[0008] Preferably, a first mounting plate is provided inside the washing chamber, and a tensioning roller is rotatably mounted on a mounting bracket. A first mounting rod is provided on the mounting bracket, passing through the first mounting plate. A long strip is provided between the extended ends of the first mounting rod, and a first spring for driving the mounting bracket to move downward is sleeved on the first mounting rod.

[0009] The drive assembly includes guide rods disposed in the washing chamber relative to each other and extending along the first mounting plate. A movable plate that can slide relative to each other is provided between the guide rods and at both ends. A lever is provided on the lower surface of the movable plate. An inclined guide groove is provided at both ends of the long block for the corresponding lever to pass through. The relative movement of the movable plate is used to drive the lever to press the corresponding guide groove to realize the lifting and lowering of the long block.

[0010] Preferably, the drive assembly also includes a rotatable shaft located above the movable plate. The two ends of the shaft are provided with drive columns corresponding to the movable plate. The outer surface of the drive column is provided with a first inclined slide groove and a second inclined slide groove. The corresponding ends of the first inclined slide groove and the second inclined slide groove are connected by a connecting slide groove. The connecting slide groove is arranged circumferentially along the drive column. A closed drive slide groove is formed between the connecting slide groove, the first inclined slide groove and the second inclined slide groove. The movable plate is provided with a sliding rod that extends into the corresponding drive slide groove and slides. The rotation of the drive column is used to drive the sliding rod to slide along the corresponding drive slide groove to realize the movement of the movable plates closer to or further apart.

[0011] Preferably, a second mounting plate is provided inside the washing chamber, and a bottom plate is provided below the second mounting plate. A second mounting rod is provided through the second mounting plate on the upper surface of the bottom plate. A second spring for driving the bottom plate to move down is sleeved on the second mounting rod. A rack is provided on the lower surface of the bottom plate at both ends.

[0012] Inside the washing chamber, there are rotatable rotating rods located on both sides of the rack. The ends of the rotating rods are equipped with gears that mesh with the rack. Support rods are provided on the rotating rods. The patting rods are located between the corresponding support rods. The rack is raised and lowered to drive the rotating rods to rotate synchronously, causing the support rods to swing relative to each other, so that the patting rods can pat the fabric.

[0013] Preferably, a push rod is provided at the lower end of the rack, and cams that cooperate with the corresponding push rods are provided at both ends of the rotating shaft. The rotation of the cams is used to drive the push rods to drive the rack to rise and fall at intervals.

[0014] Preferably, a motor for driving the rotating shaft is provided on the outer wall of the housing.

[0015] Preferably, the dewatering roller located at the top has a cavity, and the outer wall of the dewatering roller and at both ends have drainage slots that connect to the cavity. Water inlet holes for water on the fabric to flow into the cavity are evenly distributed along its axial direction on the outer wall of the dewatering roller.

[0016] The drainage assembly includes a rotating shaft rotatably disposed in the cavity, and an auger on the rotating shaft that drives the water in the cavity to flow to the corresponding drainage slot.

[0017] Preferably, one end of the rotating shaft extends out of the housing, and the extended end of the rotating shaft is provided with a first pulley; the dewatering roller located below is rotatably sleeved on a rotating column, and a second pulley is provided on one end of the rotating column corresponding to the extended end of the rotating shaft, and a transmission belt is sleeved between the first pulley and the second pulley; a drive gear is provided on the other end of the rotating column; both ends of the rotating shaft extend out of the housing, and one end of the rotating shaft is provided with a driven gear that meshes with the drive gear.

[0018] The present invention also provides a method for dyeing greige fabric, which employs the above-mentioned greige fabric dyeing system and specifically includes the following steps:

[0019] S1. Immerse the fabric to be dyed in the dyeing solution in the dyeing chamber to perform fabric dyeing treatment.

[0020] S2. After dyeing, one end of the fabric passes through the washing chamber and the dewatering chamber in sequence from the groove, so that the fabric passes through the washing mechanism and the dewatering mechanism in sequence and is connected to the existing winding device.

[0021] S3. The winding device winds the fabric at intervals. When the winding device stops winding the fabric, the motor drives the rotating shaft to rotate, which drives the tensioning roller to rise and fall at intervals, so as to relax or tension the fabric in the washing chamber at intervals. At the same time, during the relaxation of the fabric, the driving beater rod swings to beat the relaxed fabric to improve the washing effect of the fabric. At the same time, the motor drives the rotating shaft to rotate and drive the auger to rotate in the cavity, so that the cleaning water accumulated on the fabric can be discharged.

[0022] S4. After the section of fabric has been washed and dehydrated, the motor drives the rotating shaft to rotate until the tensioning roller is tensioning the fabric and then stops. At this time, the winding device starts again to wind up the fabric. After winding up a certain amount of fabric, the winding stops. Then, S3-S4 are repeated to achieve the washing and dehydration treatment of the dyed fabric.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention, through the arrangement of a dyeing chamber, a washing chamber, and a dehydration chamber, enables the fabric to be dyed in the dyeing chamber. After dyeing, the fabric passes through the washing chamber and the dehydration chamber in sequence, thereby receiving washing and dehydration treatment. Compared with existing dyeing processes, this invention can better remove excess water and dye from the fabric after dyeing, thereby reducing the time required for subsequent drying and ensuring the dyeing effect of the fabric.

[0025] 2. In this invention, by setting up a washing mechanism, the driving component can drive the tensioning roller to move up and down in the washing chamber, so as to achieve tensioning or relaxation of the fabric by the tensioning component. At the same time, when the tensioning component relaxes the fabric, the driving component can drive the beating component to beat the fabric, so as to improve the washing effect.

[0026] 3. In this invention, the dewatering mechanism is designed so that the drive component can simultaneously drive the rotating shaft to rotate the auger in the cavity while driving the washing mechanism, so that the cleaning water accumulated on the fabric can be discharged, thus preventing the cleaning water accumulated on the fabric from wetting the dewatered fabric on the other side of the dewatering roller, which would otherwise result in poor dewatering effect of the dewatering mechanism.

[0042] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0043] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0044] like Figure 1-2 As shown, a fabric dyeing system in this embodiment includes a housing 100 with internal cavities. The cavities are divided into a dyeing cavity 101, a washing cavity 102, and a dewatering cavity 103. The dyeing cavity 101 is used for dyeing the fabric. The dyeing cavity 101 stores dye; the fabric is dyed by immersing it in the dye. The washing cavity 102 is used to remove excess dye from the dyed fabric. The washing cavity 102 stores washing water; the dyed fabric is washed away by immersing it in the washing water. The dewatering cavity 103 is used to remove excess washing water from the washed fabric. In actual use, the openings of the cavities are oriented upwards, which facilitates the addition of the corresponding dyes and washing water to the dyeing cavity 101 and the washing cavity 102.

[0045] In actual use, the partition 110 is provided with a slot 201, so that the dyed fabric in the dyeing chamber 101 can pass through the washing chamber 102 and the dewatering chamber 103 in sequence through the slot 201. The side wall of the dewatering chamber 103 is provided with a discharge port 104 for the fabric to be discharged from the box 100. In actual use, the fabric discharged from the discharge port 104 can be connected to an existing winding device (not shown in the figure). By using the winding device to wind up the dyed fabric, the dyed fabric can pass through the washing chamber 102 and the dewatering chamber 103 in sequence, so that the fabric is washed and dewatered. Compared with the existing dyeing process, it can better remove the excess water and dye contained in the fabric after dyeing, so as to reduce the consumption time of subsequent drying and ensure the dyeing effect of the fabric.

[0046] In this embodiment, the washing chamber 102 is provided with a water-promoting washing mechanism for promoting the washing of the fabric, and the dewatering chamber 103 is provided with a dewatering mechanism for squeezing water out of the fabric.

[0047] The washing mechanism includes a tensioning component 210 for tensioning the fabric in the washing chamber 102 and a beating component 220 for beating the fabric. The tensioning component 210 includes a tensioning roller 211 that can be raised and lowered for tensioning the fabric. The beating component 220 includes beating rods 221 that are arranged opposite to each other. A driving component 230 is also provided in the washing chamber 102. When the driving component 230 drives the tensioning roller 211 to move upward to release the tension on the fabric, it drives the beating rods 221 to swing relative to each other to beat the fabric.

[0048] The dewatering mechanism includes dewatering rollers 240 arranged opposite each other. The dewatering roller 240 located below the fabric is rotatably arranged, and the dewatering roller 240 located above the fabric is provided with a drainage component for draining the water accumulated on the fabric.

[0049] In actual use, a clamping roller 200 for clamping the fabric is provided at the slot 201 inside the washing chamber 102 and near the dyeing chamber 101. A drive unit (not shown in the figure) for driving the clamping roller 200 to rotate and transport the fabric is provided outside the housing 100. In actual use, the drive unit can be an existing servo motor. A guide roller 130 for guiding the fabric is provided at the slot 201 inside the washing chamber 102 and near the dewatering chamber 103. Thus, the fabric can pass through the washing chamber 102 more effectively.

[0050] In this embodiment, the tensioning component 210 is installed between the clamping roller 200 and the guide roller 130, so that it can tension the fabric passing through the washing chamber 102, so that the fabric can be immersed in the washing water in the washing chamber 102, so that the fabric can be washed.

[0051] The tension roller 211 is configured such that it moves downward within the washing chamber 102 to tension the fabric, and moves upward within the washing chamber 102 to relax the fabric.

[0052] Among them, the beating component 220 is designed to beat the fabric when it is relaxed, thereby making the fabric shake in the washing water and improving the washing effect of the fabric.

[0053] Among them, by setting the relative beating rod 221, when the beating rod 221 swings relative to the other side, it can beat the loose fabric on one side of the fabric, causing the fabric to shake, thus avoiding beating the taut fabric and causing the fabric to not be able to shake in the washing water.

[0054] In this embodiment, the drive component 230 is configured to drive the tension roller 211 to move up and down within the washing chamber 102, thereby tensioning or relaxing the fabric. At the same time, when the tension component 210 relaxes the fabric, the drive component 230 can drive the patting component 220 to pat the fabric, thereby improving the washing effect.

[0055] In this embodiment, guide rollers 202 are provided in the dewatering chamber 103 and near the discharge port 104 and the groove 201. Opposite dewatering rollers 240 are located between the two guide rollers 202. The fabric entering the dewatering chamber 103 through the groove 201 is guided by the guide rollers 202, passes between the dewatering rollers 240, and is discharged from the discharge port 104. The opposite dewatering rollers 240 are used to squeeze the fabric so that excess washing water can be squeezed out of the fabric when the winding device winds up the fabric. In actual use, the rotation of the dewatering rollers 240 located below the fabric allows the dewatering rollers 240 to transport the fabric, which facilitates the winding device to wind up the fabric.

[0056] Due to the structure in this embodiment, washing water will accumulate on the upper side of the fabric near the slot 201, causing it to wet the fabric that has already been dehydrated on the other side of the dehydration roller 240. The washing water accumulated on the fabric can be better discharged into the dehydration chamber 103 through the drainage component provided in the upper dehydration roller 240, thereby ensuring the dehydration effect of the dehydration mechanism.

[0057] Combination Figure 3 and Figure 4As shown, in this embodiment, a first mounting plate 310 is provided in the washing chamber 102, and a tension roller 211 is rotatably mounted on a mounting bracket 320. A first mounting rod 321 is provided on the mounting bracket 320, which passes through the first mounting plate 310. A long strip 410 is provided between the extended ends of the first mounting rod 321, and a first spring 322 for driving the mounting bracket 320 to move downward is sleeved on the first mounting rod 321.

[0058] The drive assembly 230 includes guide rods 330 disposed in the washing chamber 102 relative to each other and extending along the first mounting plate 310. A movable plate 340 is provided between the guide rods 330 and at both ends, which can slide relative to each other. A lever 421 is provided on the lower plate surface of the movable plate 340. The two ends of the long block 410 are provided with inclined guide grooves 411 for the corresponding levers 421 to pass through. The relative movement of the movable plate 340 is used to drive the levers 421 to press the corresponding guide grooves 411 to realize the lifting and lowering of the long block 410.

[0059] In this embodiment, the two ends of the first mounting plate 310 are bent to form the first mounting part. The first mounting part is fixedly mounted on the opposite side wall of the washing chamber 102 by screws, thereby better realizing the lifting and lowering installation of the tension roller 211 in the washing chamber 102.

[0060] Among them, the lower plate surface of the movable plate 340 is provided with protrusions 422 opposite to each other, and the guide rod 330 is provided through the corresponding protrusions 422, thereby better realizing the movable plate 340 moving along the guide rod 330;

[0061] The lever 421 is U-shaped and fixedly installed on the movable plate 340 between the protrusions 422. Through the setting of the guide groove 411, when the two movable plates 340 approach each other, the lever 421 is driven to press the side wall of the corresponding guide groove 411, pushing the long strip 410 upward, thereby driving the tension roller 211 to move upward, so that the fabric is relaxed. When the two movable plates 340 move away from each other, the lever 421 is driven to press the side wall of the corresponding guide groove 411. With the setting of the first spring 322, the long strip 410 is pushed downward, thereby driving the tension roller 211 to move downward, so that the fabric is tensioned.

[0062] Combination Figure 5As shown, in this embodiment, the drive assembly 230 further includes a rotatable shaft 350 located above the movable plate 340. Drive columns 351 are provided at both ends of the shaft 350 corresponding to the movable plate 340. A first inclined slide groove 511 and a second inclined slide groove 512 are provided on the outer surface of the drive column 351. The corresponding ends of the first inclined slide groove 511 and the second inclined slide groove 512 are connected by a connecting slide groove 513. The connecting slide groove 513 is arranged circumferentially along the drive column 351. A closed drive slide groove is formed between the connecting slide groove 513, the first inclined slide groove 511 and the second inclined slide groove 512. A sliding rod 423 is provided on the movable plate 340 that extends into the corresponding drive slide groove and slides. The rotation of the drive column 351 is used to drive the sliding rod 423 to slide along the corresponding drive slide groove to realize the movement of the movable plates 340 towards or away from each other.

[0063] In actual use, a motor 120 for driving the rotating shaft 350 to rotate is provided outside the housing 100 in this embodiment, thereby better realizing the rotation of the rotating shaft 350;

[0064] The arrangement of the first inclined slide groove 511, the second inclined slide groove 512, the connecting slide groove 513, and the sliding rod 423 ensures that when the sliding rod 423 is located within the first inclined slide groove 511 or the second inclined slide groove 512, the rotation of the rotating shaft 350 drives the drive column 351 to rotate. This allows the sidewall of the first inclined slide groove 511 or the second inclined slide groove 512 to press against the sliding rod 423. Due to the limiting effect of the guide rod 330 on the moving plate 340, the sliding rod 423 can move along the first inclined slide groove 511 or the second inclined slide groove 512. 2. Sliding, thereby driving the moving plate 340 to move axially along the drive column 351. The first inclined slide groove 511 and the second inclined slide groove 512 are symmetrically arranged, and the corresponding ends of the first inclined slide groove 511 and the second inclined slide groove 512 are connected by the connecting slide groove 513 to form a closed drive slide groove. Thus, when the drive column 351 rotates one revolution, it can drive the two moving plates 340 to move closer or further away from each other. When the drive column 351 continues to rotate, the tension roller 211 can be continuously raised and lowered at intervals in the washing chamber 102.

[0065] Combination Figure 6 As shown, in this embodiment, a second mounting plate 360 ​​is also provided inside the washing chamber 102. A bottom plate 370 is provided below the second mounting plate 360. A second mounting rod 371 is provided on the upper surface of the bottom plate 370, passing through the second mounting plate 360. A second spring 372 for driving the bottom plate 370 to move downward is sleeved on the second mounting rod 371. A rack 373 is provided on the lower surface of the bottom plate 370 at both ends.

[0066] Inside the washing chamber 102, there are rotatable rotating rods 380 located on both sides of the rack 373. The ends of the rotating rods 380 are provided with gears 381 that mesh with the rack 373. Support rods 382 are provided on the rotating rods 380. The patting rod 221 is located between the corresponding support rods 382. The rack 373 is raised and lowered to drive the rotating rods to rotate synchronously, causing the support rods 382 to swing relative to each other, so that the patting rod 221 pats the fabric.

[0067] In actual use, the two ends of the second mounting plate 360 ​​are bent to form the second mounting part. The second mounting part is fixedly mounted on the opposite side wall of the washing chamber 102 by screws, thereby better realizing the installation of the patting rod 221 in the washing chamber 102.

[0068] The second mounting rod 371 has a nut threaded to its through end. The nut's limiting effect allows for the optimal installation of the base plate 370, the second mounting rod 371, and the second spring 372 on the second mounting plate 360.

[0069] The arrangement of the rotating rod 380, gear 381, and rack 373 allows the rack 373 to rotate forward and backward, thereby driving the rotating rod 380 to rotate forward and backward. Since the support rod 382 is connected to the rotating rod 380, the rotating rod 380 can swing the support rod 382 when it rotates forward and backward, thereby driving the slapping rod 221 to swing and slap the fabric.

[0070] In this embodiment, a push rod 611 is provided at the lower end of the rack 373, and cams 352 that cooperate with the corresponding push rods 611 are provided at both ends of the rotating shaft 350. The rotation of the cams 352 is used to drive the push rods 611 to drive the rack 373 to rise and fall at intervals.

[0071] With the structure in this embodiment, the rotating shaft 350 drives the cam 352 to rotate, thereby achieving the interval lifting of the top rod 611, which in turn achieves the interval lifting and lowering of the rack 373, and enables the beating rod 221 to beat the fabric.

[0072] The cam 352, which is used to lift the top rod 611, is adapted to the connecting groove 513 on the corresponding drive column 351, which is away from the cam 352. That is, when the rotating shaft 350 drives the drive column 351 to rotate and the sliding rod 423 slides in the connecting groove 513, the rotating shaft 350 can drive the cam 352 to rotate and the lifting part on it to lift the top rod 611. In other words, during one rotation cycle of the rotating shaft 350, when the tensioning assembly 210 relaxes the fabric, the rotating shaft 350 can drive the lifting part on the cam 352 to cooperate with the top rod 611, so that the rack 373 rises and falls once, and the patting rod 221 swings once to pat the relaxed fabric, thereby improving the washing effect.

[0073] Combination Figure 7 As shown, in this embodiment, the dewatering roller 240 located at the top has a cavity inside. The outer wall of the dewatering roller 240 and at both ends are provided with drainage slots 711 that communicate with the cavity. Water inlet holes 391 for water on the fabric to flow into the cavity are evenly distributed along its axial direction on the outer wall of the dewatering roller 240.

[0074] The drainage assembly includes a rotating shaft 720 rotatably disposed in the cavity, and an auger 721 on the rotating shaft 720 for driving the water in the cavity to flow to the corresponding drainage slot 711.

[0075] In this embodiment, the water inlet 391 is positioned facing the side of the fabric where the washing water accumulates. This allows the accumulated washing water to enter the cavity through the water inlet 391, which in turn causes the rotating shaft 720 to drive the auger 721 to rotate and transport the washing water in the cavity to the end of the cavity. Due to the drainage slot 711 provided at the end, the washing water in the cavity can flow into the dewatering chamber 103, thereby better draining the washing water accumulated on the fabric and preventing the washing water accumulated on the fabric from wetting the dewatered fabric on the other side of the dewatering roller 240.

[0076] In this embodiment, one end of the rotating shaft 350 extends out of the housing 100, and the extended end of the rotating shaft 350 is provided with a first pulley 521; the dewatering roller 240 located below is rotatably sleeved on a rotating column 392, and both ends of the rotating column 392 extend through the housing 100. A second pulley is provided on one end of the rotating column 392 corresponding to the extended end of the rotating shaft 350, and a transmission belt 522 is sleeved between the first pulley 521 and the second pulley. A drive gear 132 is provided on the other end of the rotating column 392, and both ends of the rotating shaft 720 extend out of the housing 100. One end of the rotating shaft 720 is provided with a driven gear 131 that meshes with the drive gear 132.

[0077] Through the structure in this embodiment, the rotating shaft 350 can drive the rotating shaft 720 to rotate through the driven gear 131 and the driving gear 132, and through the driving gear 132 and the driven gear 131. That is, when the washing mechanism is working, it can drive the dewatering mechanism and the drainage component to operate synchronously, making the structure of the fabric dyeing system more compact.

[0078] This embodiment also provides a method for dyeing greige fabric, which uses the above-described greige fabric dyeing system and specifically includes the following steps:

[0079] S1. Immerse the fabric to be dyed in the dyeing solution in the dyeing chamber 101 to perform fabric dyeing treatment.

[0080] S2. After dyeing, one end of the fabric passes through the groove 201 in sequence through the washing chamber 102 and the dewatering chamber 103, so that the fabric passes through the washing mechanism and the dewatering mechanism in sequence and is connected to the existing winding device.

[0081] S3. The winding device winds the fabric at intervals. When the winding device stops winding the fabric, the motor 120 drives the rotating shaft 350 to rotate, which drives the tension roller 211 to rise and fall at intervals, thereby relaxing or tensioning the fabric in the washing chamber 102 at intervals. At the same time, during the relaxation of the fabric, the driving beater 221 swings to beat the relaxed fabric, thereby improving the washing effect of the fabric. At the same time, the motor 120 drives the rotating shaft 350 to rotate and also drives the rotating shaft 720 to drive the auger 721 to rotate in the cavity, so that the clean water accumulated on the fabric can be discharged.

[0082] S4. After the section of fabric has been washed and dehydrated, the motor 120 drives the rotating shaft 350 to rotate until the tension roller 211 is tensioning the fabric and then stops. At this time, the winding device starts again to wind up the fabric. After winding up a certain amount of fabric, the winding stops. Then, S3-S4 are performed again to achieve the washing and dehydration treatment of the dyed fabric.

[0083] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
