Description

Technical Field

[0001] The invention relates to the technical field of dyeing machines, and more specifically to a rectangular nozzle cloth guide tube capable of dyeing multiple cloths and a dyeing machine. Background Art

[0002] Most of the air overflow dyeing machines in the dyeing industry use O-type dyeing machines and round cloth guides. The cloth guides are used in conjunction with round nozzles. The dye liquid is sprayed out by a water pump, and the cloth is pushed by the dye liquid and the fan to move the cloth. Due to the blockage of the cloth and the attenuation of the pressure of the water pump and the fan, it is not easy to move over a long distance, so it can only be manufactured in the form of an O-type. Due to the limitations of the internal space of the O-type dyeing machine, the general loading capacity is small (about 250-300 kg for a single tube), and the O-type dyeing machine easily causes the cloth to be squeezed by gravity at the bottom of the cloth groove. The squeezed cloth cannot stretch well on the one hand, and it is easy to cause uneven coloring (dyeing), and it is very easy to have dyeing problems such as wrinkle marks and chicken claw marks, which affects the overall quality of the cloth. And because the cloth runs in a rope-like state in the round nozzle and the round cloth guide tube, the round nozzle and the round cloth guide tube are prone to generate eddy currents, which will drive the cloth to rotate. If a single tube and two branches are running, they are very likely to be entangled with each other, causing knots and blockages, affecting the dyeing process and quality. And before entering the cloth tank, the cloth needs to be manipulated by a manipulation device to manipulate the cloth front and back, left and right, so that the cloth can be stacked evenly. The following solutions are proposed to address the above problems. Summary of the invention

[0010] Furthermore, the connection between the second fabric guiding pipe and the third fabric guiding pipe is transitioned through an arc.

[0013] Furthermore, an air suction port is provided at one end of the dye vat shell.

[0014] Furthermore, a quick-opening cloth inlet and outlet hole is provided at one end of the dye vat housing close to the cloth inlet and outlet rack.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. In this scheme, the dye liquid nozzle assembly and the air nozzle assembly are separated, and water spray or air spray can be focused on according to different varieties. It is flexible and saves electricity. The second cloth guide tube arranged downwardly can utilize the gravity of the dye liquid and the cloth to accelerate the movement of the cloth and avoid blockage. At the same time, the design of the rectangular tube can make the cloth run in a half-width shape, increase the color eating area, thereby reducing the number of cycles, shortening the dyeing process, and reducing the damage to the cloth surface. At the same time, the upwardly inclined third cloth guide tube can increase the effective height of the dye vat as a whole, and ensure sufficient length space (cloth capacity) for subsequent cloth operation, thereby realizing the reflux of the entire cloth and dye liquid. The high-pressure gas generated by the centrifugal fan enters the fourth cloth guide tube through the air inlet duct to accelerate the penetration of the dye liquid into the cloth. At the same time, it has a slapping effect on the cloth, so that the fabric opens, increases the soft feel of the cloth, and reduces the use of softener. In addition, the airflow can stretch the cloth, increase the contact area with the dye, and accelerate the dyeing efficiency of the cloth by the dye liquid. At the same time, the airflow will assist in pushing the cloth to move, thereby increasing the movement speed of the cloth and the dye liquid.

[0017] Second, the higher end of the third cloth guide tube is lower than the higher end of the second cloth guide tube, which can ensure that the cloth and the dye can reach this position during the movement to avoid energy consumption. At the same time, when the lower end of the third cloth guide tube is lower than the air inlet, a siphon phenomenon will occur, further accelerating the movement speed of the cloth and the dye to avoid blockage and avoiding the occurrence of water backflow in the dye inlet duct.

[0018] 3. The third cloth guide tube adopts a trumpet-shaped design. The end of the third cloth guide tube with a smaller area is connected to the second cloth guide tube (3), which can ensure the pressure when the dye enters the third cloth guide tube, thereby ensuring the movement rate of the dye and the cloth. The end of the air nozzle assembly connected to the third cloth guide tube has a larger area, which can facilitate the airflow ejected from the nozzle to stretch the cloth and reserve enough space for the cloth.

[0019] 4. The cloth and dye liquid enter the outlet pipe through the inlet pipe, and the airflow generated by the centrifugal fan enters the inside of the air chamber. The airflow then enters the outlet pipe through the air inlet duct between the inlet pipe and the outlet pipe. The air inlet duct is arranged obliquely, and the air inlet nozzle faces the direction of the cloth movement, so that the cloth and dye liquid are pushed by the airflow.

[0020] 5. The 10°-30° arc transition design formed between the second cloth guide tube and the third cloth guide tube can ensure the smooth movement of the cloth. The flow of the cloth during the arc transition can form a flapping effect on the outer arc surface, thereby helping the fabric to open and increase the hand feel.

[0021] 6. The design of the second fabric guide tube being tilted downward by 2-15 degrees can ensure acceleration through gravity, while avoiding compression of the subsequent length space due to excessive angle.

[0022] 7. After the cloth, dye and air flow pass through the fourth cloth guide tube, they enter the inside of the cloth stacking tube. When the cloth moves to this point, the cloth will block the pores of the rear end pore surface (19) of the cloth stacking tube due to the impact force. The greater the flow rate, the smaller the pressure. The cloth naturally falls due to gravity. Since the cloth blocks the pores of the rear end pore surface, the air escapes to the inner side of the front end pore surface of the cloth stacking tube, thereby driving the cloth to approach the inner side. The cloth blocks the pores of the front end pore surface, and the cloth naturally falls due to gravity. This is repeated, and the cloth naturally forms a reciprocating swing, folds and is stored. Since a large amount of dye carried by the cloth when entering the cloth stacking tube will escape from the pores of the front end pore surface, the rear end pore surface and the side pore surface, the escape of the dye will reduce the impact on the The impact and weight of the stored cloth reduce the cloth transportation speed and cause cloth blockage. A water shield is installed on the rear end air hole surface to block water on all sides after a certain distance away from the outer periphery of the air holes on the rear end air hole surface. The gas can only escape upward, and the dye liquid naturally flows back into the stacking tube from the air holes below. When the cloth is folded to a certain height in the stacking tube, gravity is naturally formed, and under the impact of gas and liquid flow, it slides into the cloth trough and moves forward. At the same time, the air escapes to the stacking tube under the suction of the centrifugal fan inlet and is separated from the dye liquid and cloth, and circulated through the centrifugal fan. The cloth flows to the front end again through the cloth trough, and a circulation is formed inside through the cloth belt device, the rectangular nozzle cloth guide tube, the stacking tube and the cloth trough, and the dye liquid is circulated through the circulating water pump.

[0023] 8. The air inlet is used to balance the air pressure inside and outside the dye tank shell.

[0024] 9. The quick-opening fabric inlet and outlet holes are used to facilitate the removal of processed fabrics. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] Embodiment 1:

[0036] See also Figure 1-8 A rectangular nozzle cloth guide tube for dyeing multiple cloths comprises a dye liquid nozzle assembly 1, a first cloth guide tube 2, a second cloth guide tube 3, a third cloth guide tube 4 and an air nozzle assembly 5. The dye liquid nozzle assembly 1 and the air nozzle assembly 5 are separated and can focus on water spraying or air spraying depending on different varieties. It is flexible and saves electricity.

[0037] The dye liquid nozzle assembly 1 includes a water nozzle housing 8, a water spray port 7 and a water nozzle channel 9. The water nozzle housing 8 is a sealed end shape. The water spray port 7 passes through one end of the water nozzle housing 8, and the water nozzle channel 9 passes through the other end of the water nozzle housing 8. One end of the water spray port 7 is arranged inside the water nozzle channel 9, and a liquid inlet for the dye liquid to enter the water nozzle channel 9 is formed between the external upper and lower end surfaces of one end of the water spray port 7 and the internal upper and lower end surfaces of one end of the water nozzle channel 9. A water nozzle water inlet 11 is fixed to the outside of the water nozzle housing 8, one end of the water nozzle water inlet 11 passes through the water nozzle housing 8 and is connected, one end of the water nozzle channel 9 is connected to the first cloth guide pipe 2 through the water nozzle sealing end 10, and the first cloth guide pipe 2 and the second cloth guide pipe 3 are fixedly connected.

[0038] The second cloth guide tube 3 is connected to the third cloth guide tube 4, and the second cloth guide tube 3 is arranged in a continuous downward inclination in the vertical direction from one end close to the first cloth guide tube 2 to the other end, and the inclination of the second cloth guide tube 3 is between 2-15 degrees. The design of the second cloth guide tube 3 being inclined downward at 2-15 degrees can ensure the acceleration effect through gravity, and at the same time can avoid the subsequent length space being compressed by too large an angle. The third cloth guide tube 4 is arranged in a continuous upward state in the vertical direction from one end close to the second cloth guide tube 3 to the other end, and the connection between the second cloth guide tube 3 and the third cloth guide tube 4 is transitioned by an arc. The arc transition design of 10°-30° formed between the second cloth guide tube 3 and the third cloth guide tube 4 can ensure the smooth movement of the cloth. The flow of the cloth during the arc transition can form a slapping effect on the outer arc surface, thereby helping the fabric to open the fibers and increase the feel. The higher end of the third cloth guide tube 4 is at a lower height in the vertical plane than the higher end of the second cloth guide tube 3 The height of one end of the third cloth guide tube 4 on the vertical plane, the higher end of the third cloth guide tube 4 is lower than the higher end of the second cloth guide tube 3, which can ensure that the cloth and the dye can reach this position during the movement, avoiding energy consumption. The third cloth guide tube 4 is in a flat trumpet shape, that is, the cross-sectional area of ​​one end of the third cloth guide tube 4 connected to the second cloth guide tube 3 is smaller than the cross-sectional area of ​​the other end, and the length of the cross-sectional area from one end of the third cloth guide tube 4 close to the second cloth guide tube 3 to the other end is continuously expanding, and the inner diameter height of the third cloth guide tube 4 remains unchanged. The third cloth guide tube 4 is similar to a trumpet shape, and the smaller end of the third cloth guide tube 4 is connected to the second cloth guide tube 3, which can ensure the pressure of the dye when entering the third cloth guide tube 4, thereby ensuring the moving rate of the dye and the cloth. The end of the wind nozzle assembly 5 connected to the third cloth guide tube 4 has a larger area, which can facilitate the airflow ejected from the nozzle to stretch the cloth and reserve enough space for the cloth, thereby realizing the reflux of the overall cloth and dye.

[0039] The wind nozzle assembly 5 is arranged horizontally, and the wind nozzle assembly 5 includes a wind nozzle housing 15, an inlet pipe 13 and an outlet pipe 16. The wind nozzle housing 15 is provided with a wind chamber 14. The wind nozzle housing 15 is provided with a wind nozzle air inlet 6. The wind nozzle air inlet 6 is connected to the wind chamber 14. The wind nozzle air inlet 6 is used to be connected to the output end of the centrifugal fan. One end of the inlet pipe 13 passes through one end of the wind nozzle housing 15 and is arranged inside the wind chamber 14. One end of the inlet pipe 13 is connected to the third guide pipe 4 through the wind nozzle sealing end 12. The outlet pipe 16 passes through the other end of the wind nozzle housing 15, and the inlet pipe 1 One end of the third cloth guide pipe 4 is arranged inside one end of the outlet pipe 16, the upper and lower side surfaces of one end of the inlet pipe 13 will form an air inlet with the upper and lower side surfaces inside one end of the outlet pipe 16, the air inlet is connected to the wind chamber 14, the height of the air inlet is between 15-50 mm, the width of the air inlet is between 400-1200 mm, the distance between the lower opening of the third cloth guide pipe 4 and the air inlet is between 100-600 mm, when the lower opening of the third cloth guide pipe 4 is lower than the air inlet, a siphon phenomenon will occur, further accelerating the movement speed of the cloth and the dye liquid, avoiding blockage, and at the same time avoiding the occurrence of backflow in the dye liquid inlet.

[0040] The cloth and the dye liquid enter into the outlet pipe 16 through the inlet pipe 13, and the airflow generated by the centrifugal fan enters into the wind chamber 14 at the same time, and then enters into the outlet pipe 16 through the air inlet duct between the inlet pipe 13 and the outlet pipe 16. The air inlet duct is arranged at an angle, and the airflow blows in the direction of the movement of the cloth, and the cloth and the dye liquid are pushed by the airflow. The high-pressure gas generated by the centrifugal fan can accelerate the penetration of the dye liquid into the cloth, and at the same time has a beating effect on the cloth, so that the fabric is opened, the soft feel of the cloth is increased, and the use of softener is reduced. In addition, the airflow can stretch the cloth, increase the contact area with the dye, and accelerate the dyeing efficiency of the cloth by the dye liquid. At the same time, the airflow will assist in pushing the cloth to move, thereby increasing the movement speed of the cloth and the dye liquid.

[0041] One end of the outlet pipe 16 is connected to the fourth cloth guide pipe 29, and the end of the fourth cloth guide pipe 29 away from the wind nozzle assembly 5 is vertically downward. The cross-sections of the water spray port 7, the water nozzle channel 9, the first cloth guide pipe 2, the second cloth guide pipe 3, the third cloth guide pipe 4, the inlet pipe 13, the outlet pipe 16 and the fourth cloth guide pipe 29 are all rectangular. The design of the rectangular tube can make the cloth run in half width, increase the color absorption area, thereby reducing the number of cycles, shortening the dyeing process, and reducing damage to the cloth surface.

[0042] Example 2

[0043] The difference from the first embodiment is that the rectangular nozzle cloth guide pipe 30 is included, and the cloth inlet and outlet rack 21, the cloth belt device 23, the cloth groove 26 and the dyeing cylinder housing 25 are also included. The rectangular nozzle cloth guide pipe 30 is arranged inside the dyeing cylinder housing 25, and the centrifugal fan is installed outside the dyeing cylinder housing 25. The input end of the centrifugal fan is connected to the dyeing cylinder housing 25, and the output end of the centrifugal fan is connected to the air nozzle inlet 6 of the rectangular nozzle cloth guide pipe 30. The cloth inlet and outlet rack 21 is arranged at the input end of the dyeing cylinder housing 25. A cloth feed roller is rotatably arranged on the cloth inlet and outlet rack 21, and the cloth feed roller is used to facilitate the transportation of cloth to the inside of the dyeing cylinder housing 25. The cloth belt device 23 is rotatably arranged on the dyeing cylinder housing 2 5, and the cloth-carrying device 23 is located at the input end of the dye liquid nozzle assembly 1 of the rectangular nozzle cloth-guiding pipe 30, the cloth-carrying device 23 is a cloth-carrying roller, and the cloth-carrying roller is rotatably connected to the dye cylinder housing 25, a dye liquid outlet 24 is provided at the lower part of the dye cylinder housing 25, the dye liquid outlet 24 is communicated with the water nozzle water inlet 11 of the rectangular nozzle cloth-guiding pipe 30 through a circulating water pump, an air suction port 28 is provided at one end of the dye cylinder housing 25, and the air suction port 28 is used to balance the air pressure inside and outside the dye cylinder housing 25, and a quick-opening cloth inlet and outlet hole 22 is provided at one end of the dye cylinder housing 25 close to the cloth inlet and outlet rack 21, and the quick-opening cloth inlet and outlet hole 22 is used to facilitate the removal of the processed cloth.

[0044] The cloth groove 26 is located inside the dye vat shell 25 and is fixedly connected, and the cloth groove 26 is located at the bottom of the rectangular nozzle cloth guide tube 30. The fourth cloth guide tube 29 of the rectangular nozzle cloth guide tube 30 is connected to the stacking cloth tube 27. The stacking cloth tube 27 is an L-shaped curved tube. The cross-section of the stacking cloth tube 27 is rectangular. The stacking cloth tube 27 includes a front end air hole surface 17, a rear end air hole surface 19, a side air hole surface 18 and a water shield 20. The front end air hole surface 17, the rear end air hole surface 19, and the side air hole surface 18 are respectively arranged on the four sides of the vertical end of the stacking cloth tube 27. The water shield 20 is installed on one side of the rear end air hole surface 19. The water shield 20 and the stacking cloth tube 27 are fixedly connected. The output end of the stacking cloth tube 27 and one end of the cloth groove 26 are connected to each other. The end of the cloth groove 26 away from the stacking cloth tube 27 is provided with a perforated plate, and the perforated plate is used to separate the dye solution and the cloth.

[0045] The cloth, dye solution and air flow pass through the fourth cloth guide tube 29 and enter the inside of the cloth stacking tube 27. When the cloth moves to this point, the cloth will block the pores of the rear end pore surface 19 of the cloth stacking tube 27 due to the impact force. The greater the flow rate, the smaller the pressure. The cloth naturally falls due to gravity. Since the cloth blocks the pores of the rear end pore surface 19, the air escapes to the inside of the front end pore surface 17 of the cloth stacking tube 27, thereby driving the cloth to move closer to the inside. The cloth blocks the pores of the front end pore surface 17, and the cloth naturally falls due to gravity. This process is repeated, and the cloth naturally forms a reciprocating swing, folds and is stored.

[0046] Since a large amount of dye liquid carried by the cloth when entering the stacking tube 27 will escape from the pores of the front pore surface 17, the rear pore surface 19 and the side pore surface 18, the escape of the dye liquid will reduce the impact and weight on the stored cloth, reduce the cloth transportation speed and cause cloth blockage, a water shield 20 is installed at the rear pore surface 19, and the water is blocked on all sides after the pores of the rear pore surface 19 are separated from the periphery of the pores of the rear pore surface 19 by a certain distance, so that the gas can only escape upward, and the dye liquid naturally flows back into the stacking tube 2 from the pores of the rear pore surface 19 7, when the cloth is folded to a certain height in the cloth stacking tube 27, gravity is naturally formed, and it slides into the cloth groove 26 under the impact of air and liquid flow and moves forward. At the same time, the air escapes to the cloth stacking tube 27 under the suction of the centrifugal fan inlet, and is separated from the dye liquid and the cloth, and circulated through the centrifugal fan. The cloth flows to the front end again through the cloth groove 26, and a circulation is formed inside through the cloth belt device 23, the rectangular nozzle cloth guide tube 30, the cloth stacking tube 27 and the cloth groove 26, and the dye liquid is circulated through the circulating water pump.

[0047] The thickness of the cloth varies greatly. The present application is operated with half the width opened. Therefore, two, three or four cloths can be overlapped and operated according to the thickness of the cloth without being entangled with each other, so there is no need to sew or remove the edges. The end of the cloth groove 26 is inclined upward by 5-30 degrees and is provided with a perforated plate for separating the cloth and the dye liquid. The cloth is driven by the dye liquid, airflow and slope behind it, and synchronously climbs at the upward inclined part, so that most of the dye liquid is separated from the cloth, which can reduce the amount of dye liquid dragged when the cloth is lifted and operated, reduce the tension of the cloth surface, increase the dyeing rate of the cloth to accept new dye liquid, shorten the time for cleaning residual liquid, and save the amount of cleaning water and auxiliary agent.
