Description

Technical Field

[0001] The invention relates to the field of dyeing, in particular to a high-temperature open-width gas-liquid dyeing device and a gas-liquid dyeing method thereof. Background Art

[0002] Dyeing is dyeing, also known as coloring, which means using chemical or other methods to affect the material itself to make it colored. Under technical conditions, dyeing can make objects present various colors that people need, and decorate life with colorful colors. The method of dyeing has existed since ancient times and has been continuously developed.

[0003] The existing dyeing method is usually immersion dyeing, which involves injecting a dyeing medium into a dyeing container and immersing the fabric back and forth. However, this method requires multiple back and forth transfers of the fabric to allow the fabric to be immersed in the dyeing medium for a sufficient amount of time before dyeing can be completed. At the same time, the immersion dyeing method consumes a large amount of water resources during dyeing. Summary of the invention

[0004] Purpose of the invention: To provide a high-temperature open-width gas-liquid dyeing device and a gas-liquid dyeing method thereof to solve the above-mentioned problems existing in the prior art.

[0005] Technical solution: A high-temperature open-width gas-liquid dyeing device and a gas-liquid dyeing method thereof, comprising:

[0006] A base, and a dyeing part arranged on the base;

[0007] The dyeing part comprises:

[0008] A cavity is arranged above the base;

[0009] A heat-insulating top, arranged on the top of the inner wall of the cavity;

[0010] A reciprocating mechanism is arranged inside the cavity and below the heat-insulating top;

[0011] The spray heating mechanism is arranged at the bottom of the inner wall of the cavity, and comprises a constant pressure spray component arranged in the cavity, and the constant pressure spray component is used for spraying dyeing medium on the dyeing fabric on the reciprocating mechanism.

[0012] The present invention designs a constant pressure spray part in the cavity to complete the aerosol pressure difference dyeing on the fabric, replacing the traditional immersion dyeing method. Due to the aerosol pressure difference dyeing, the dyeing medium is directly sprayed onto the fabric during dyeing, and the dyeing medium is immersed into the inner layer of the fabric fiber by the aerosol pressure difference, which greatly reduces the dyeing time.

[0013] At the same time, compared with the immersion dyeing method, the aerosol pressure difference spraying method greatly reduces the water consumption. At the same time, due to the aerosol pressure difference dyeing, there is no wastewater discharge after immersion dyeing, which is more environmentally friendly and has lower operating costs.

[0014] In a further embodiment, the thermal insulation roof comprises:

[0015] An arc top shell is connected to the cavity and has a predetermined arc;

[0016] The serpentine pipe is arranged on the arc top shell, located between the arc top shell and the inner wall of the cavity, and has an inlet and an outlet, and the inlet is externally connected to a steam source.

[0017] A steam trap is provided at the outlet position, the outlet extends outside the cavity, and the outlet is used to discharge the steam after heat conduction through the serpentine shell, as well as the condensed water formed by the steam and the inner wall;

[0018] The steam trap is designed to continuously discharge the condensed water in the serpentine pipe to the outside of the pipe. The back pressure of the steam trap is designed to discharge the serpentine pipe at a constant pressure. At the same time, the steam trap can be controlled to discharge at a fixed time in conjunction with the control system.

[0019] By designing a heat preservation top for preheating, it is prevented that when the steam is injected into the steam heating port to heat up, it will contact with the top of the cavity to form condensed water, thus preventing the condensed water from dripping on the fabric, and preventing excessive condensed water from affecting the temperature in the cavity and damaging the color fixing work of the fabric;

[0020] At the same time, high-temperature steam is injected into the serpentine tube to increase the temperature of the serpentine tube, thereby evaporating part of the moisture in the air in the cavity, thereby achieving the effect of humidity control.

[0021] The present invention designs a constant pressure spray part in the cavity to complete the aerosol pressure difference dyeing on the fabric, replacing the traditional immersion dyeing method. Due to the aerosol pressure difference dyeing, the dyeing medium is directly sprayed onto the fabric during dyeing, and the dyeing medium is immersed into the inner layer of the fabric fiber by the aerosol pressure difference, which greatly reduces the dyeing time.

[0022] At the same time, compared with the immersion dyeing method, the aerosol pressure difference spraying method greatly reduces the water consumption. At the same time, due to the aerosol pressure difference dyeing, there is no wastewater discharge after immersion dyeing, which is more environmentally friendly and has lower operating costs.

[0023] In a further embodiment, the reciprocating mechanism comprises

[0024] Two groups of tension flat-width winding members are arranged in the cavity, and peach-shaped rollers are arranged below the tension flat-width winding members, and the two groups of tension flat-width winding members are symmetrically arranged in an initial state;

[0025] Each set of tension flat-width winding parts includes:

[0026] A flat-width winding roller is arranged in the cavity and has a driving motor at its end;

[0027] The driving motor is a vector servo motor.

[0028] The tensioning member comprises a buffer tension frame hinged in the cavity and located below the flat-width winding roller, and a first flat-width member and a second flat-width member arranged on the buffer tension frame, and a tension adjusting spring is arranged between the buffer tension frame and the cavity;

[0029] There is a predetermined angle between the tension adjustment spring and the buffer tension frame.

[0030] A cloth guide member is arranged in the cavity, and is located below the second flat member and includes a first cloth guide roller and a second cloth guide roller which are arranged in sequence.

[0031] In a further embodiment, the first flat-web member is located between the second flat-web member and the flat-web take-up roller;

[0032] The first flattening member and the second flattening member can be selected from any of the flattening devices such as an elliptical flattening roller, a spiral flattening roller, a scraper, a linear roller, etc., among which the elliptical flattening roller is more advantageous;

[0033] Different flattening devices can be selected for the first flattening member and the second flattening member;

[0034] When the flat-width member is an elliptical flat-width roller, the diameters of the first flat-width member and the second flat-width member gradually increase from both ends to the middle.

[0035] The design of this flat-width roller can prevent the flat-width fabric from wrinkling during operation. During movement, the fabric spreads from the larger middle position of the tension-adjusting roller to both sides, thereby stretching the fabric and preventing the fabric from wrinkling.

[0036] In a further embodiment, the constant pressure spraying parts are designed in two groups, which are respectively arranged on the sides of the two groups of first cloth guide rollers and second cloth guide rollers;

[0037] include:

[0038] A constant pressure nozzle is disposed in the cavity;

[0039] The nozzles are designed in multiple groups and are arranged on the constant pressure nozzle.

[0040] When the reciprocating mechanism moves, the nozzle and constant pressure nozzle on the side of the flat-width winding roller close to the material discharge are built with dyeing medium for dyeing, and the nozzle and constant pressure nozzle on the other side are built with water source for cleaning the part of the dyeing medium that has not penetrated into the fabric.

[0041] The nozzle can be selected according to actual working conditions, and a fan-shaped atomizing nozzle, a conical atomizing nozzle, a spiral atomizing nozzle, etc. can be selected.

[0042] Select the nozzle according to the actual working conditions to achieve better spraying effect.

[0043] In a further embodiment, the spray heating mechanism also includes a steam inlet pipe arranged in the cavity, and a plurality of steam heating ports arranged on the steam inlet pipe. The steam inlet pipe is externally connected to a steam source, and steam is injected into the cavity through the steam heating port to increase the temperature. After the steam is injected, the humidity in the cavity can also be changed.

[0044] The steam inlet pipe and the steam heating port, as the main heating components in the cavity, cooperate with the heat preservation top as the auxiliary heating component to complete the temperature control of the entire cavity. The main and auxiliary components cooperate with each other to improve the temperature control accuracy in the cavity.

[0045] In a further embodiment, a control unit is further provided on one side of the dyeing unit, and a color adjustment unit is provided on one side of the control unit;

[0046] The color mixing unit includes a color mixing container and a stirring mechanism arranged in the color mixing container;

[0047] The color mixing container is connected to the constant pressure nozzle, and the constant pressure nozzle is pre-filled with dyeing medium by designing a pump body, and the pressure required for spraying and dyeing by multiple nozzles is calculated, and the required pressure of all nozzles is provided by the pump body to form a constant pressure;

[0048] The control unit is connected to the dyeing unit and the color adjusting unit, and is used to control the coordinated work of the color adjusting unit and the dyeing unit.

[0049] A high-temperature open-width gas-liquid dyeing method comprising:

[0050] Step 1, during dyeing, the fabric pre-wound on the reciprocating mechanism is driven to move by the reciprocating mechanism. When the fabric is wound, the fabric passes through a flat-width winding roller in a group of tension flat-width winding parts, passes above the first flat-width part, below the second flat-width part, above the first cloth guide roller, below the second cloth guide roller, above the peach-shaped roller, and then passes below the second cloth guide roller in another group of tension flat-width winding parts, above the first cloth guide roller, below the second flat-width part, and above the first flat-width part to be rolled onto the flat-width winding roller. When the fabric moves, the drive motor corresponding to the flat-width winding roller rotates forward and reverse to complete the reciprocating work;

[0051] Step 2: When the reciprocating mechanism is running, the tension adjusting spring and the buffer tension frame are used to make the fabric have constant tension when it moves. At the same time, the diameter of the first flat piece and the second flat piece is gradually increased from both ends to the middle, so that the fabric runs without wrinkles.

[0052] Step 3, during the dyeing process, the dyeing medium after the color adjustment part is colored is pumped into the constant pressure nozzle through the pump body for pre-filling, and finally the fabric between the first cloth guide roller and the second cloth guide roller is sprayed and dyed through the nozzle. When the pump body is working, the control unit needs to pre-calculate the pressure required for spraying and dyeing of multiple nozzles, and the pump body provides the required pressure of all nozzles to form a constant pressure state. At the same time, under the action of the nozzle, the dyeing medium is hydraulically atomized, and at the same time, the constant pressure nozzle on the other side is filled with water, which is sprayed out through the nozzle to wash the dyed fabric, which is used to clean the part of the dyeing medium that has not penetrated into the fabric;

[0053] Step 4: During the dyeing process, the temperature in the cavity is controlled by the heat preservation top and the steam heating port. Steam is injected into the cavity through the steam heating port to adjust the temperature in the cavity. At the same time, steam is injected into the heat preservation top serpentine tube to avoid condensation water on the top of the cavity and affect the temperature in the cavity. The temperature in the cavity is controlled to complete the color fixing of the fabric.

[0054] Beneficial effects: The present invention discloses a high-temperature flat-width gas-liquid dyeing device and a gas-liquid dyeing method thereof. The present invention designs a constant-pressure spraying part in the cavity to complete gas mist pressure difference dyeing on the fabric, replacing the traditional immersion dyeing method. Due to the gas mist pressure difference dyeing, the dyeing medium is directly sprayed onto the fabric during dyeing, and the dyeing medium is immersed in the inner layer of the fabric fiber by the gas mist pressure difference, which greatly reduces the dyeing time;

[0055] At the same time, compared with the immersion dyeing method, the aerosol pressure difference spraying method greatly reduces the water consumption. At the same time, due to the aerosol pressure difference dyeing, there is no wastewater discharge after immersion dyeing, which is more environmentally friendly and has lower operating costs.

The constant pressure spray member 342 is used to spray the dyeing medium on the dyeing fabric on the reciprocating mechanism 33.

[0078] The traditional dyeing method requires multiple dyeing to dye the dyeing medium into the inner layer of the fabric fiber. The present application uses aerosol pressure difference dyeing to allow the dyeing medium to penetrate into the inner layer of the fabric fiber in a spraying manner.

[0079] In traditional dyeing, the dyeing medium is immersed into the limiting inner layer by the water absorption of the fabric itself. In the present application, the dyeing medium is pressurized by the constant pressure spray part 342, and the dyeing medium is immersed into the limiting inner layer by adding external force, so the dyeing efficiency is greatly improved.

[0086] The present invention designs a constant pressure spraying part 342 in the cavity 31 to perform aerosol pressure difference dyeing on the fabric, replacing the traditional immersion dyeing method. Due to the aerosol pressure difference dyeing, the dyeing medium is directly sprayed onto the fabric during dyeing, and the dyeing medium is immersed into the inner layer of the fabric fiber by the aerosol pressure difference, which greatly reduces the dyeing time.

[0090] Each set of tension flat-width winding parts includes:

[0091] The flat-width winding roller 331 is arranged in the cavity 31 and has a driving motor at its end;

[0092] A tensioning member, comprising a buffer tension frame 334 hinged in the cavity 31 and located below the flat-width winding roller 331, and a first flat-width member 335 and a second flat-width member 336 arranged on the buffer tension frame 334, and a tension adjusting spring 333 is arranged between the buffer tension frame 334 and the cavity 31;

[0093] The cloth guide member is arranged in the cavity 31 and is located below the second flat member 336 and includes a first cloth guide roller 337 and a second cloth guide roller 338 which are arranged in sequence.

[0096] A constant pressure nozzle 3421 is disposed in the cavity 31;

[0097] The nozzles 3422 are designed in multiple groups and are arranged on the constant pressure nozzle 3421.

[0098] In a further embodiment, the spray heating mechanism 34 further includes a steam heating port 341 disposed in the cavity 31 , and the steam heating port 341 is externally connected to a steam source.

[0099] The dyeing unit 3 is also provided with a control unit on one side, and a color adjustment unit is provided on one side of the control unit;

[0100] The color mixing unit includes a color mixing container and a stirring mechanism arranged in the color mixing container;

[0101] The color mixing container is connected to the constant pressure nozzle 3421.

[0102] The control unit is connected to the dyeing unit 3 and the color adjusting unit, and is used to control the coordinated work of the color adjusting unit and the dyeing unit 3.

[0103] In another embodiment, with the rest of the structure unchanged, the cavity 31 is divided into two parts, including a fixed cavity and a movable cavity;

[0104] The heat-insulating top 32 is arranged on the top of the inner wall of the activity cavity;

[0105] A reciprocating mechanism 33 is arranged inside the cavity 31, below the heat preservation top 32, and connected to the fixed cavity;

[0106] The spray heating mechanism 34 is arranged at the bottom of the inner wall of the movable cavity.

[0107] A walking mechanism 35 is provided at the bottom of the outer wall of the movable cavity;

[0108] The walking mechanism 35 comprises:

[0109] Walking roller 354, installed at the bottom of the outer wall of the movable cavity;

[0110] A travel rack 353, mounted on the bottom of the outer wall of the movable cavity;

[0111] A travel motor 351 is mounted on the base 4, and an output end thereof has an output shaft, and the output shaft sleeve is provided with a travel gear 352 adapted to the travel rack 353;

[0112] The base 4 is provided with a track adapted to the travel roller 354 .

[0113] The movable cavity is moved to an appropriate position through the walking mechanism 35, and the output shaft is driven to rotate by the walking motor 351, thereby driving the walking gear 352 to rotate, and then the moving walking rack 353 moves, so that the walking roller 354 moves along the base 4, so that the movable cavity and the fixed cavity are separated or contacted. When separated, except that the reciprocating mechanism 33 is connected to the fixed cavity and does not move, the remaining structures in the cavity 31 move with the movable cavity. This design makes it more convenient to load and unload the fabric on the reciprocating mechanism.

[0114] A high-temperature open-width gas-liquid dyeing method comprising:

[0115] Step 1, during dyeing, the fabric pre-wound on the reciprocating mechanism 33 is driven to move by the reciprocating mechanism 33. When the fabric is wound, the fabric passes through a flat-width winding roller 331 in a group of tension flat-width winding parts, passes above the first flat-width part 335, below the second flat-width part 336, above the first cloth guide roller 337, below the second cloth guide roller 338, above the peach-shaped roller 339, and then passes below the second cloth guide roller 338 in another group of tension flat-width winding parts, above the first cloth guide roller 337, below the second flat-width part 336, and above the first flat-width part 335, and is rolled onto the flat-width winding roller 331. When the fabric moves, the driving motor corresponding to the flat-width winding roller 331 rotates forward and reversely to complete the reciprocating work;

[0116] Step 2: When the reciprocating mechanism 33 is in operation, the tension adjusting spring 333 and the buffer tension frame 334 are used to make the fabric have a constant tension during movement. Meanwhile, the diameters of the first flat piece 335 and the second flat piece 336 are gradually increased from both ends to the middle, so that the fabric can be moved without wrinkles.

[0117] Step 3, during the dyeing process, the dyeing medium after the color adjustment part is colored is pumped into the constant pressure nozzle 3421 through the pump body for pre-filling, and finally the fabric between the first cloth guide roller 337 and the second cloth guide roller 338 is sprayed and dyed through the nozzle 3422. When the pump body is working, the control unit needs to pre-calculate the pressure required for spraying and dyeing of multiple nozzles 3422, and the pump body provides the required pressure of all nozzles 3422 to form a constant pressure state. At the same time, under the action of the nozzle 3422, the dyeing medium is hydraulically atomized;

[0118] At the same time, the constant pressure nozzle 3421 on the other side is filled with water, which is sprayed out through the nozzle 3422 to wash the dyed fabric, so as to clean the part of the dyeing medium that has not penetrated into the fabric;

[0119] Step 4: During the dyeing process, the temperature in the cavity 31 is controlled by the heat preservation top 32 and the steam heating port 341. Steam is injected into the cavity 31 through the steam heating port 341 to adjust the temperature in the cavity 31. At the same time, steam is injected into the serpentine tube 322 of the heat preservation top 32 to avoid condensation water from forming on the top of the cavity 31 and to avoid affecting the temperature in the cavity 31. The temperature control in the cavity 31 is then completed to complete the color fixing work of the fabric.

[0120] Working principle description: During dyeing, the reciprocating mechanism 33 drives the fabric pre-wound on the reciprocating mechanism 33 to move. When the fabric is wound, the fabric passes through a flat-width winding roller 331 in a group of tension flat-width winding parts, passes above the first flat-width part 335, below the second flat-width part 336, above the first cloth guide roller 337, below the second cloth guide roller 338, above the peach-shaped roller 339, and then passes below the second cloth guide roller 338 in another group of tension flat-width winding parts, above the first cloth guide roller 337, below the second flat-width part 336, and above the first flat-width part 335, and is rolled onto the flat-width winding roller 331. When the fabric moves, the drive motor corresponding to the flat-width winding roller 331 rotates forward and reverse to complete the reciprocating work;

[0121] When the reciprocating mechanism 33 is in operation, the tension adjusting spring 333 and the buffer tension frame 334 are used to make the fabric have constant tension during movement. At the same time, the diameters of the first flat piece 335 and the second flat piece 336 gradually increase from both ends to the middle, so that the fabric can be moved without wrinkles.

[0122] During the dyeing process, the dyeing medium after the color adjustment part is colored is pumped into the constant pressure nozzle 3421 through the pump body for pre-filling, and finally the fabric between the first cloth guide roller 337 and the second cloth guide roller 338 is sprayed and dyed through the nozzle 3422. When the pump body is working, the control part needs to pre-calculate the pressure required for spraying and dyeing of multiple nozzles 3422, and the pump body provides the required pressure of all nozzles 3422 to form a constant pressure state. At the same time, under the action of the nozzle 3422, the dyeing medium is hydraulically atomized;

[0123] During the dyeing process, the temperature in the cavity 31 is controlled by the heat preservation top 32 and the steam heating port 341. Steam is injected into the cavity 31 through the steam heating port 341 to adjust the temperature in the cavity 31. At the same time, steam is injected into the serpentine pipe 322 of the heat preservation top 32 to avoid condensation water from forming on the top of the cavity 31 and affecting the temperature in the cavity 31. The temperature control in the cavity 31 is then completed to complete the color fixing work of the fabric.

[0124] When the cavity 31 needs to be moved, the cavity 31 is moved to an appropriate position through the walking mechanism 35, and the output shaft is driven to rotate by the walking motor 351, thereby driving the walking gear 352 to rotate, and then driving the walking rack 353 to move, thereby causing the walking roller 354 to move along the base 4, and then the cavity 31 is moved to the working position.

6. The high temperature open width gas-liquid dyeing equipment according to claim 1, characterized in that: The spray heating mechanism (34) also includes a steam heating port (341) arranged in the cavity (31).

7. A high temperature open width gas-liquid dyeing method, characterized in that: include: Step 1, during dyeing, the fabric pre-wound on the reciprocating mechanism (33) is driven to move by the reciprocating mechanism (33). When the fabric is wound, the fabric passes through a flat-width winding roller (331) in a group of tension flat-width winding parts, passes above the first flat-width part (335), below the second flat-width part (336), above the first cloth guide roller (337), below the second cloth guide roller (338), above the peach-shaped roller (339), and then passes below the second cloth guide roller (338) in another group of tension flat-width winding parts, above the first cloth guide roller (337), below the second flat-width part (336), and above the first flat-width part (335) to be rolled onto the flat-width winding roller (331). When the fabric moves, the driving motor corresponding to the flat-width winding roller (331) rotates forward and reverse to complete the reciprocating work; Step 2, when the reciprocating mechanism (33) is in operation, the tension adjusting spring (333) and the buffer tension frame (334) are used to make the fabric present constant tension during movement, and at the same time, the diameters of the first flat piece (335) and the second flat piece (336) are gradually increased from both ends to the middle, so that the fabric can be moved without wrinkles; Step 3, during the dyeing process, the dyeing medium after the color adjustment part is colored is pumped into the constant pressure nozzle (3421) through the pump body for pre-filling, and finally the fabric between the first cloth guide roller (337) and the second cloth guide roller (338) is sprayed and dyed through the nozzle (3422). When the pump body is working, the control unit needs to pre-calculate the pressure required for spraying and dyeing of multiple nozzles (3422), and the pump body provides the required pressure of all nozzles (3422) to form a constant pressure state. At the same time, under the action of the nozzle (3422), the dyeing medium is hydraulically atomized; Step 4: During the dyeing process, the temperature in the cavity (31) is controlled by the heat-insulating top (32) and the steam heating port (341). Steam is injected into the cavity (31) through the steam heating port (341) to adjust the temperature in the cavity (31). At the same time, steam is injected into the serpentine tube (322) of the heat-insulating top (32) to avoid the formation of condensed water on the top of the cavity (31) and to avoid affecting the temperature in the cavity (31). The temperature in the cavity (31) is controlled in coordination to complete the color fixing work of the fabric.
