Description
Technical Field
[0001] This utility model relates to the field of textile fabric processing technology, specifically a textile fabric dyeing device. Background Technology
[0002] Textile fabrics are the core materials for clothing, home furnishings and industrial products. During the processing, dyeing equipment is often used to dye the fabrics.
[0003] Existing textile fabric dyeing devices include a dyeing tank with two rotatable dyeing rollers installed inside. A first guide roller and a second guide roller are rotatably installed on both sides of the port of the dyeing tank, respectively. When dyeing the fabric, the fabric is first passed through the first guide roller into the dyeing tank in sequence, then through the bottom of the two dyeing rollers, and finally out through the second guide roller. When the fabric passes through the dyeing roller at the bottom of the dyeing tank, the dyeing of the fabric is completed.
[0004] Before dyeing, textile fabrics often have dust, lint, fiber debris, and other impurities attached to their surface. Existing textile fabric dyeing devices lack effective dust removal mechanisms and cannot effectively remove these impurities before dyeing. These impurities affect the uniform adsorption of dye, leading to quality problems such as color difference, uneven dyeing, or decreased fastness. Furthermore, after dyeing, excess dye liquor attached to the fabric cannot be squeezed out and recycled, resulting in waste of dye liquor and increased dyeing costs. Therefore, a textile fabric dyeing device is proposed to address these issues. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background art, this utility model proposes a textile fabric dyeing device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A textile fabric dyeing device of this utility model includes a dyeing pool. Two first supports and second supports are fixedly connected to both sides of the top of the dyeing pool. Two first guide rollers are rotatably mounted on the two first supports, and two fourth guide rollers are rotatably mounted on the two second supports. A lower dust collection hood is fixedly connected between the two first supports. A support frame is fixedly connected to the top side of the two first supports. An upper dust collection hood is fixedly connected to the inner walls of both sides of the support frame. A dust collection box is installed on the top side of the support frame. Dust collection pipes are connected to both sides of the dust collection box, and two dust collection holes at the other end of each dust collection pipe are respectively connected to the upper and lower dust collection hoods. A negative pressure pump is installed on the dust collection box, and an air extraction pipe is connected to the input port of the negative pressure pump. The output port of the negative pressure pump is connected to the exhaust pipe. Two dyeing rollers are rotatably installed inside the dyeing tank. A second guide roller is rotatably installed between the inner walls on both sides of the dyeing tank. Vertical plates are fixed to both sides of the opening of the dyeing tank. A third guide roller is rotatably installed between the two vertical plates. Before dyeing, the negative pressure pump operates to extract the gas in the dust collection box through the suction pipe and discharge it through the exhaust pipe, so that the inside of the dust collection box is in a negative pressure state. This allows the dust, lint, and fiber debris attached to the upper and lower dust collection hoods to be effectively sucked into the upper and lower dust collection hoods and flow into the dust collection box through the suction pipe. This effectively removes and collects the dust, lint, and fiber debris attached to the fabric surface, avoiding problems such as color spots and color variations during dyeing, resulting in a uniform color of the dyed fabric and improving the dyeing quality.
[0007] Preferably, the dust collection box is equipped with an arc-shaped filter screen, which surrounds the air extraction pipe. When using this device, the arc-shaped filter screen can prevent the air extraction pipe port from becoming blocked, ensuring the normal operation of subsequent dust collection.
[0008] Preferably, a discharge port is provided on one side of the dust collection box, and a limiting slide rail is fixed to both sides of the discharge port. The two limiting slide rails are fitted with a sealing cover plate. When using the device, the discharge port can be opened or closed as needed through the cooperation of the limiting slide rails and the sealing cover plate. By setting the discharge port, it is convenient to take out the impurities collected in the dust collection box.
[0009] Preferably, triangular plates are fixed to both sides of the opening of the dyeing pool, and three pressing rollers are rotatably installed between the two triangular plates. A fixing frame is installed on the top side of the two triangular plates, and two pneumatic cylinders are installed on the top side of the fixing frame. Pneumatic rods are fitted to the working ends of the two pneumatic cylinders, and pressing plates are installed at the bottom ends of the two pneumatic rods. After the fabric is dyed, when it passes between the pressing rollers and the pressing plates, the mechanical pressure of the pressing rollers and the pressing plates can squeeze out the excess dye liquor and drip it back into the dyeing pool, avoiding waste of dye liquor and saving dye costs. At the same time, by appropriately squeezing out the excess dye liquor, the dye liquor can better combine with the fiber fabric, enhance the color fastness, ensure uniform dye penetration, and improve the overall dyeing quality of the fabric.
[0010] Preferably, a frame is fixed between the two second supports. Two mounting holes are provided on the top and bottom sides of the frame. A spiral heating wire is installed in each mounting hole. A fixing ring is fixed to the end of each mounting hole, and a grid is fitted inside each fixing ring. A rotating rod is rotatably mounted on each grid. A fan is fitted at one end of each rotating rod, and a first pulley and a second pulley are respectively fitted at the other ends of the two rotating rods. An electric motor is installed on the top and bottom sides of the frame. The output end of the electric motor is connected to a rotating shaft. A third pulley and a fourth pulley are respectively fitted on the rotating shaft. A first conveyor belt is fitted onto the first and third pulleys. The second conveyor belt is fitted with the fourth and fifth pulleys. After the fabric is dyed, as it passes through the frame, the control panel controls two motors to operate synchronously, causing two rotating shafts to rotate. These shafts drive the third and fourth pulleys to rotate. With the cooperation of the first and second conveyor belts, multiple rotating rods drive multiple fans to rotate. With the help of spiral heating wires, the heated high-temperature gas is evenly blown onto both sides of the fabric, thus effectively drying the dyed fabric and accelerating the curing of the dye solution. At the same time, by heating both sides of the fabric simultaneously, color difference or deformation caused by drying on one side is avoided, improving the quality of the fabric.
[0011] Preferably, a drain pipe is connected to the bottom of one side of the dyeing pool, and a one-way valve is installed on the drain pipe. After the fabric is dyed, the remaining dye solution in the dyeing pool 1 can be discharged by setting up the drain pipe.
[0012] Preferably, a control panel is installed on the outer wall of the dyeing pool, and the control panel is used to control the start and stop of the negative pressure pump, the motor and the pneumatic cylinder. When using the device, by setting up the control panel, multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.
[0013] The advantages of this utility model are:
[0014] 1. Before dyeing, this utility model uses a negative pressure pump to extract the gas in the dust collection box through the suction pipe and discharge it through the exhaust pipe, creating a negative pressure state inside the dust collection box. This effectively draws dust, lint, and fiber debris adhering to the upper and lower dust hoods into the upper and lower dust hoods, and then flows into the dust collection box through the suction pipe. This effectively removes and collects dust, lint, and fiber debris adhering to the fabric surface, preventing color spots and uneven coloring during dyeing, resulting in a uniform color in the dyed fabric and improving the dyeing quality.
[0015] 2. After the fabric is dyed, when it passes between the pressing roller and the pressing plate, the mechanical pressure of the pressing roller and the pressing plate can squeeze out the excess dye liquor and drip it back into the dyeing pool, thus avoiding waste of dye liquor and saving dye costs. At the same time, by properly squeezing out the excess dye liquor, the dye liquor can be better combined with the fiber fabric, enhance the color fastness, ensure uniform dye penetration, and improve the overall dyeing quality of the fabric.
[0016] 3. After the fabric is dyed, as it passes through the frame, the control panel controls two motors to operate synchronously, causing two rotating shafts to rotate. These shafts drive the third and fourth pulleys to rotate. With the cooperation of the first and second conveyor belts, multiple rotating rods drive multiple fans to rotate. With the help of spiral heating wires, the heated high-temperature gas is evenly blown onto both sides of the fabric, thus effectively drying the dyed fabric and accelerating the curing of the dye solution. At the same time, by heating both sides of the fabric simultaneously, color difference or deformation caused by drying on one side is avoided, thus improving the quality of the fabric.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0029] Please see Figure 1-5As shown, a textile fabric dyeing device includes a dyeing tank 1. Two first supports 2 and second supports 3 are fixedly connected to both sides of the top of the dyeing tank 1.

An upper dust collection hood 8 is fixedly connected to the inner walls of both sides of the support frame 6. A dust collection box 9 is installed on the top side of the support frame 6. Dust collection pipes 10 are connected to both sides of the dust collection box 9, and two dust collection holes at the other end of the dust collection pipes 10 are respectively connected to the upper dust collection hood 8 and the lower dust collection hood 7. A negative pressure pump 11 is installed on the dust collection box 9. The input port of the negative pressure pump 11 is connected to a suction pipe 12, and the output port of the negative pressure pump 11 is connected to an exhaust pipe 13.

Two dyeing rollers 36 are installed between the inner walls of the two sides of the dyeing pool 1, and two vertical plates 38 are fixed to the opening of the dyeing pool 1. A third guide roller 39 is installed between the two vertical plates 38. During operation, before dyeing, when the fabric passes through the first guide roller 4, the negative pressure pump 11 operates to extract the gas in the dust collection box 9 through the exhaust pipe 12 and discharge it through the exhaust pipe 13, so that the dust collection box 9 is in a negative pressure state. This allows the dust, lint, and fiber debris attached to the upper and lower surfaces of the fabric to be effectively sucked into the upper dust hood 8 and the lower dust hood 7 and flow into the dust collection box 9 through the dust suction pipe 10. This effectively removes and collects the dust, lint, and fiber debris attached to the fabric surface, avoiding problems such as color spots and color variations during dyeing, making the dyed fabric uniform in color and improving the dyeing quality.
[0030] The dust collection box 9 is equipped with an arc-shaped filter screen, which surrounds the air extraction pipe 12. When using this device, the arc-shaped filter screen can prevent the air extraction pipe 12 from becoming blocked, ensuring the normal operation of subsequent dust collection.
[0031] A discharge port is provided on one side of the dust collection box 9. Both sides of the discharge port are fixedly connected to limit slide rails 14. The two limit slide rails 14 are slidably fitted with sealing cover plates 15. When using the device, the discharge port can be opened or closed as needed by the cooperation of the limit slide rails 14 and sealing cover plates 15. By setting the discharge port, it is easy to take out the impurities collected in the dust collection box 9.

Three pressing rollers 32 are rotatably installed between the two triangular plates 31. A fixed frame 33 is installed on the top side of the two triangular plates 31. Two pneumatic cylinders 34 are installed on the top side of the fixed frame 33. Pneumatic rods are fitted to the working ends of the two pneumatic cylinders 34. Pressing plates 35 are installed at the bottom ends of the two pneumatic rods. During operation, after the fabric is dyed, when it passes between the pressing rollers 32 and the pressing plates 35, the mechanical pressure of the pressing rollers 32 and the pressing plates 35 can squeeze out the excess dye liquor and drip it back into the dyeing pool 1, avoiding waste of dye liquor and saving dye costs. At the same time, by properly squeezing out the excess dye liquor, the dye liquor can be better combined with the fiber fabric, enhancing the dye fastness, ensuring uniform dye penetration, and improving the overall dyeing quality of the fabric.

A spiral heating wire 18 is installed in each mounting hole 17. A fixing ring 19 is fixed to the end of each mounting hole 17. A grille 20 is installed in each fixing ring 19.

During operation, after the fabric is dyed, when the fabric passes through the frame 16, the control panel 41 controls the two motors 25 to work synchronously, causing the two rotating shafts 26 to rotate. The rotating shafts 26 drive the third pulley 27 and the fourth pulley 28 to rotate. With the cooperation of the first conveyor belt 29 and the second conveyor belt 30, multiple rotating rods 21 drive multiple fans 22 to rotate. With the cooperation of the spiral heating wire 18, the heated high-temperature gas is blown evenly to the top and bottom surfaces of the fabric, thereby effectively drying the dyed fabric, accelerating the curing of the dye liquor, and simultaneously heating both sides of the fabric to avoid color difference or deformation caused by drying on one side, thus improving the quality of the fabric.
[0034] Please see Figure 2 As shown, a drain pipe 40 is connected to the bottom of one side of the dyeing pool 1, and a one-way valve is installed on the drain pipe 40. During operation, after the fabric is dyed, the remaining dye solution in the dyeing pool 1 can be discharged by setting up the drain pipe 40.
[0035] A control panel 41 is installed on the outer wall of the dyeing pool 1, and the control panel 41 is used to control the start and stop of the negative pressure pump 11, the motor 25 and the pneumatic cylinder 34. When using this device, by setting up the control panel 41, multiple drive devices can be centrally controlled together, which greatly improves the convenience of operation.
[0036] Working Principle: Before dyeing, textile fabrics often have dust, lint, fiber debris, and other impurities adhering to their surface. Existing textile fabric dyeing devices lack effective dust removal mechanisms, failing to effectively remove these impurities before dyeing. These impurities affect the uniform adsorption of dye, leading to quality problems such as color difference, uneven dyeing, or decreased fastness. Furthermore, after dyeing, excess dye liquor adhering to the fabric cannot be squeezed out and recycled, resulting in dye liquor waste and increased dyeing costs. Therefore, this paper proposes a textile fabric dyeing device to address these issues. Before dyeing, When the fabric passes through the first guide roller 4, the negative pressure pump 11 operates, causing the gas in the dust collection box 9 to be extracted through the suction pipe 12 and discharged through the exhaust pipe 13, so that the inside of the dust collection box 9 is in a negative pressure state. This allows the dust, lint, and fiber debris attached to the upper and lower surfaces of the fabric to be effectively sucked into the upper dust hood 8 and the lower dust hood 7, and then flow into the dust collection box 9 through the suction pipe 10. This effectively removes and collects the dust, lint, and fiber debris attached to the surface of the fabric, avoiding problems such as color spots and color variations during dyeing, and ensuring that the dyed fabric has a uniform color, thus improving the dyeing quality.
[0037] After the fabric is dyed, when it passes between the pressing roller 32 and the pressing plate 35, the mechanical pressure of the pressing roller 32 and the pressing plate 35 can squeeze out the excess dye liquor and drip it back into the dyeing pool 1, avoiding waste of dye liquor and saving dye costs. At the same time, by properly squeezing out the excess dye liquor, the dye liquor can better combine with the fiber fabric, enhance the color fastness, ensure uniform dye penetration, and improve the overall dyeing quality of the fabric.
[0038] After the fabric is dyed, as it passes through the frame 16, the control panel 41 controls two motors 25 to operate synchronously, causing two rotating shafts 26 to rotate. The rotating shafts 26 drive the third pulley 27 and the fourth pulley 28 to rotate. With the cooperation of the first conveyor belt 29 and the second conveyor belt 30, multiple rotating rods 21 drive multiple fans 22 to rotate. With the cooperation of the spiral heating wire 18, the heated high-temperature gas is evenly blown onto both sides of the fabric, thereby effectively drying the dyed fabric, accelerating the curing of the dye liquor, and simultaneously heating both sides of the fabric to avoid color difference or deformation caused by drying on one side, thus improving the quality of the fabric.
