Description

Technical Field

[0001] This invention relates to the field of fabric dyeing machine technology, specifically to a fabric dyeing machine that improves dyeing efficiency. Background Technology

[0002] Fabric dyeing machines are specialized equipment used in the textile industry to dye various fabrics such as cotton, linen, silk, and chemical fibers. They mainly use a conveying mechanism to feed the fabric into the dyeing system, and combine core functions such as precise dye ratio and temperature and time control to achieve uniform dye adhesion and color fixation on the fabric fibers. Some machines also integrate post-processing steps such as washing and drying. Common types include rope dyeing machines suitable for knitted fabrics and flat-width dyeing machines suitable for woven fabrics. Their core function is to meet the diverse color requirements of textiles while ensuring dyeing uniformity, color fastness, and production efficiency. They are key equipment in the finishing process of textiles.

[0003] In the process of dyeing fabrics, dyeing machines are usually used. However, traditional dyeing machines often have limitations in the way the fabric moves (such as the fabric easily getting knotted and overlapping in rope dyeing machines, and the fabric being passively moved by the impact of the dye liquor in overflow dyeing machines). This results in insufficient contact of the fabric with the dye liquor in some areas, which can easily lead to color spots, white spots, or uneven shades. Secondly, they have high energy and water consumption and low dye utilization. Most dyeing machines require high-power water pumps to circulate the dye liquor to ensure uniformity, which consumes a lot of energy. Moreover, "circulation dead zones" are easily formed in the corners and bottom of the dyeing vat, and the dye that has not participated in the dyeing is discharged with the wastewater, with a utilization rate of only 70%-80%. In addition, some equipment exerts strong pulling and friction on the fabric (such as airflow dyeing machines if the airflow speed is out of control), resulting in low dyeing efficiency, low dye liquor circulation efficiency, and uneven mixing. Based on this, a fabric dyeing machine that improves dyeing efficiency is proposed. Summary of the Invention

The specifications and dimensions of the square tube sleeve are adapted to the specifications and dimensions of the rotating square tube, and positioning holes are opened on the outside of the magnetic hoop.

[0009] Preferably, the scraper and the infrared heater are evenly distributed circumferentially inside the cylinder, and the scraper and the infrared heater are located on both sides of the heat insulation partition plate. Several temperature sensors are installed on the inner walls at both ends of the cylinder, and the temperature sensors are evenly distributed circumferentially inside the cylinder.

[0010] Preferably, an insulation layer is fixedly sleeved inside the mounting groove, and an electric heating layer is fixedly sleeved inside the mounting groove. The insulation layer is located outside the electric heating layer, and the electric heating layer corresponds to the position of the scraper.

[0011] Preferably, the driven gear ring is meshed with a driving gear on its outer side, and a gearbox is driven to one side of the driving gear. A geared drive motor is driven to the input end of the gearbox, and both the geared drive motor and the gearbox are fixedly mounted on the top of the base.

[0012] Preferably, the rotary sealing structure includes a guide tube and a concave circular frame. The guide tube is fixedly inserted through the cylinder and communicates with the interior of the cylinder. The guide tube is evenly distributed circumferentially inside the cylinder. A transverse support ring is fixedly sleeved on the outer side of the guide tube. Sealing bearings are sleeved on the inner sides of both sides of the transverse support ring. The other side of the sealing bearings is sleeved on the inner wall of the concave circular frame. The concave circular frame is a concave-top rectangle. Sealing cones are sleeved on the inner sides of both sides of the transverse support ring. Sealing cones are fixedly installed inside the concave circular frame. The wall has two sealing cones fixedly sleeved on the outer sides of both sides of the horizontal support ring. The sealing cones are movably sleeved on the inner wall of the concave circular frame. Rotary seals are embedded in the inner sides of both sides of the horizontal support ring. The outer side of the rotary seal is movably installed with the inner side of the concave circular frame. The opposite sides of the sealing bearing are provided with outer seals. The opposite sides of the outer seals are fixedly installed on the side wall of the concave circular frame. The outer side of the outer seal is in movable contact with the horizontal support ring. The specifications of the second rotary seal structure and the first rotary seal structure are the same.

[0013] Preferably, the top of the outlet pipe is connected to an addition pipe, and a valve is installed inside the addition pipe. The heat-resistant water pump and the closed liquid filter are both fixedly installed on the top of the base. The extraction pipe is connected to the bottom of the rotary sealing structure. A discharge valve is movably installed inside the discharge pipe. The position of the rotary sealing structure corresponds to the position of the scraper. Both the outlet pipe and the extraction pipe are equipped with one-way valves.

[0014] Preferably, the outlet pipe is connected to the bottom of the rotary sealing structure two, the top of the intake pipe is connected to a pressure relief pipe, the heat-resistant air pump and the sealed condenser are both fixedly installed on the top of the base, the intake pipe and the outlet pipe are both equipped with one-way valves, and the pressure relief pipe is equipped with a pressure relief valve.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the equipment is in use, the operator places two square tube sleeves parallel to the outside of the rotating square tube, and then sequentially and cyclically connects multiple sets of square tube sleeves to the outside of the rotating square tube. A portion of the fabric is pulled out and wrapped around the bottom of the rotating roller. The sealed door is closed, and the synchronous double-head drive motor is slowly and synchronously started, driving one rotating square tube to wind up and the other rotating square tube to unwind, so that the fabric is slowly wound up and unwound. This allows the rotating roller and the wrapped fabric to be placed inside the dyeing solution. The reduction drive motor drives the gearbox and the drive gear to reciprocate the driven gear ring, causing the cylinder to shake in the early stage of dyeing. This helps to keep the dyeing solution in place, assists the fabric in dyeing, and promotes the fabric to circulate and soak in the dyeing solution. This helps to maintain the uniformity of the dyeing solution, avoid sedimentation, and reduce circulation dead zones. By using multiple square tube sleeves, the number of fabrics that can be placed for dyeing is increased, thus increasing the dyeing efficiency.

[0016] 2. With the infrared heater installed, the fabric can be taken out after the previous dyeing and placed inside the cylinder where the infrared heater is located. After repeating the installation method of the square tube sleeve, the rotating square tube is driven by the synchronous double-head drive motor. The dyeing operation is carried out inside one end of the cylinder, and the hot drying operation is carried out inside the other end. The dyeing and drying operations can be carried out simultaneously, which increases the utilization efficiency of the equipment.

[0017] 3. When the cylinder rotates, it will drive the guide pipe and the horizontal support ring to rotate. The rotary seal will rotate and seal the opposite sides of the horizontal support ring and the concave circular frame. As the cylinder rotates, the water outlet pipe will input water flow to the opposite sides of the concave circular frame and the horizontal support ring. At this time, the fluid will pass through the guide pipe and connect to the inside of the cylinder under the limitation of the horizontal support ring and the concave circular frame. This ensures the passage of fluid while the cylinder is rotating, which is convenient for auxiliary operations, facilitates stable rotation and fluid balance, and provides space for fluid to enter and exit, thus increasing the effectiveness of use.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-9This invention provides a technical solution: a fabric dyeing machine for improving dyeing efficiency, comprising a cylinder 1 and a square tube sleeve 35. Sealed doors 4 are movably installed at both ends of the cylinder 1. A plurality of heat-insulating partition plates 26 are fixedly installed in the middle of the cylinder 1. Two synchronous double-head drive motors 25 are fixedly sleeved in the middle of the heat-insulating partition plates 26. Rotating square tubes 21 are driven to both ends of the two synchronous double-head drive motors 25. A rotating roller 41 is movably installed through the bottom of the heat-insulating partition plates 26 via sealed bearings. A plurality of scrapers 20 are fixedly installed on the inner wall of one end of the cylinder 1. A plurality of infrared heaters 24 are fixedly installed inside the other end of the cylinder 1. An installation groove 23 is opened inside the cylinder 1. A plurality of support bearings 3 are sleeved on the outer side of the cylinder 1. A support leg frame 2 is sleeved on the outer side of the support bearings 3. A bottom plate is fixedly installed at the bottom of the support leg frame 2. A driven toothed ring 12 is fixedly sleeved on the outer side of the cylinder 1. A rotary sealing structure 6 is movably sleeved on the outer side of the cylinder 1. A water outlet pipe 8 is connected to the outer side of the rotary sealing structure 6. A heat-resistant water pump 30 is connected to the other end of the water outlet pipe 8. A closed liquid filter 31 is connected to the input end of the heat-resistant water pump 30. An extraction pipe 32 is connected to the input end of the closed liquid filter 31. A discharge pipe 33 is connected to one side of the extraction pipe 32. A rotary sealing structure 7 is movably sleeved on the outer side of the other end of the cylinder 1. An air suction pipe 11 is connected to the top of the rotary sealing structure 7. A heat-resistant air pump 14 is connected to the other end of the air suction pipe 11. A closed condenser box 15 is connected to the output end of the heat-resistant air pump 14. A drain valve 16 is connected to one side of the bottom of the closed condenser box 15. An air outlet pipe 13 is connected to the output end of the closed condenser box 15.

[0030] A take-up roller sleeve 36 is fixedly sleeved on the outside of the square tube sleeve 35. A trapezoidal groove 37 is provided on one side of the take-up roller sleeve 36. A trapezoidal clip 38 is movably inserted into the inside of the trapezoidal groove 37. Magnetic hoops 39 are fixedly installed at both ends of the square tube sleeve 35.

[0031] The working principle of the above technical solution is as follows: During use, the operator uses a square tube sleeve 35 to roll up the fabric to be processed and wrap it around the outside. Then, another square tube sleeve 35 is taken out, and a trapezoidal clip 38 is pulled out. One end of the fabric is placed inside the trapezoidal groove 37, and the trapezoidal clip 38 is slid in. The two square tube sleeves 35 are placed parallel to each other on the outside of the rotating square tube 21. Multiple sets of square tube sleeves 35 are sequentially and cyclically connected to the outside of the rotating square tube 21. A portion of the fabric is pulled out and wrapped around the bottom of the rotating roller 41. After placement, the limiting seat 22 is installed on the outside of the bolt seat 27 using bolts. After the sealing door 4 is closed, the dyeing solution is added into the cylinder 1 through the adding pipe 9 and the rotating sealing structure 6. Then, the synchronous dual-head drive motor 25 starts slowly and synchronously, driving one rotating square tube 21 to wind up and the other rotating square tube 21 to unwind, so that the fabric is slowly wound up and unwound. Then, the reduction drive motor 18 starts and drives the driven gear ring 12 through the gearbox 17 and the drive gear 19, causing the cylinder 1 to rotate under the support of the support frame 2 and the support bearing 3. At this time, the square tube sleeve 35 that has just been wound up is immersed in the dyeing solution and resets as the operation progresses, so that the rotating roller 4 1. The fabric and its loops are placed inside the dyeing solution. The dyeing process is carried out slowly by a synchronous dual-head drive motor 25. In one dyeing mode, the reduction drive motor 18 drives the gearbox 17 and the drive gear 19 to reciprocate through the driven gear ring 12, causing the cylinder 1 to sway in the early stage of dyeing. This helps to keep the dyeing solution in position and assists in dyeing the fabric. When dyeing fabrics that require multiple dyeing cycles, the reduction drive motor 18 drives the gearbox 17 and the drive gear 19 to reciprocate around the driven gear ring 12 in a circular motion, causing the fabric to sway within the dyeing solution. Circulating immersion helps maintain the uniformity of the dyeing solution, avoids sedimentation, and reduces dead zones in the circulation. The number of fabrics that can be placed for dyeing is increased by using multiple square tube sleeves 35, which increases the dyeing efficiency. The infrared heater 24 can be installed to remove the fabrics after the previous dyeing round and place them inside the cylinder 1 where the infrared heater 24 is located. The installation and placement of the square tube sleeves 35 can be repeated. The rotating square tube 21 is driven by the synchronous double-head drive motor 25. Dyeing is carried out inside one end of the cylinder 1, and heat drying is carried out inside the other end. Dyeing and drying can be carried out simultaneously, which increases the utilization efficiency of the equipment.

[0032] In another implementation scheme, such as Figures 1-4 As shown, two synchronous dual-head drive motors 25 are evenly distributed axially symmetrically on the inner side of the heat insulation partition plate 26. Several sealed bearings 28 are sleeved on the end of the rotating square tube 21 away from the synchronous dual-head drive motors 25. The rotating square tube 21 is movably installed through the sealed bearings 28 on the inner side of the heat insulation partition plate 26. The rotating roller 41 is located at the bottom of the cylinder 1. The rotating roller 41 and the synchronous dual-head drive motors 25 are triangularly distributed on the inner side of the heat insulation partition plate 26.

[0033] The synchronous dual-head drive motor 25 is a specially designed heat-resistant motor with synchronous dual-head output control. The heat from dyeing and drying inside the cylinder 1 is separated by the outermost heat insulation partition plate 26, reducing the impact of high temperature on the synchronous dual-head drive motor 25. The heat insulation partition plate 26 also provides rolling support for the synchronous dual-head drive motor 25, the rotating square tube 21, and the rotating roller 41, so that the two synchronous dual-head drive motors 25 drive the rotating square tube 21 to perform winding and unwinding operations respectively. The rotating roller 41 limits the movement of the fabric, ensuring the efficiency of the dyeing operation and increasing the ease of use of the structure. Unlike traditional dyeing machines, it can balance dyeing efficiency and work effect, increasing the operating efficiency of the equipment.

[0034] In another implementation scheme, such as Figure 2 As shown, bolt seats 27 are fixedly installed inside both ends of the rotating roller 41 and the rotating square tube 21. Limit seats 22 are installed on the outside of the bolt seats 27 by bolts. The specifications and dimensions of the square tube sleeve 35 are compatible with the specifications and dimensions of the rotating square tube 21. A positioning hole 40 is opened on the outside of the magnetic hoop 39.

[0035] The bolt seat 27, through the bolt-fixed limiting seat 22, serves to position the square tube sleeves 35 after they are joined together and placed on the outside of the rotating square tube 21. The opposite ends of the square tube sleeves 35 are attracted and positioned by the magnetic clamps 39. The outermost square tube sleeve 35 is limited by the limiting seat 22 to prevent it from falling off and ensure a stable position. The take-up roller sleeve 36 is a traditional take-up fabric roller modified by trapezoidal grooves 37 and trapezoidal clips 38 to adapt to the working mode in the scheme, increasing the efficiency of the operation. The square design allows the rotating square tube 21 to rotate synchronously with the square tube sleeve 35, facilitating transmission and increasing the usability of the structure.

[0036] In another implementation scheme, such as Figure 2 As shown, the scraper 20 and the infrared heater 24 are evenly distributed in a circular pattern inside the cylinder 1. The scraper 20 and the infrared heater 24 are located on both sides of the heat insulation partition plate 26. Several temperature sensors 29 are installed on the inner walls at both ends of the cylinder 1. The temperature sensors 29 are evenly distributed in a circular pattern inside the cylinder 1.

[0037] The scraper 20 is used to lift the dyeing liquid when the cylinder 1 shakes and rotates in a circular motion, reducing sedimentation and ensuring the uniformity and stability of the dyeing liquid. The infrared heater 24 dries the fabric through infrared radiation, and the synchronous dual-head drive motor 25 applies rotation and winding to the fabric, and the cyclic rotation of the cylinder 1 provides uniform heating for the drying process, increasing the efficiency of the operation. Multiple temperature sensors 29 are distributed to facilitate the detection of temperature at different locations, such as the temperature inside the dyeing liquid and the inner cavity of the cylinder 1. The infrared heater 24 on one side can detect the top and bottom of the inner cavity, indirectly determining the temperature at the air inlet and outlet, and assisting in the detection of the temperature inside the cylinder 1, which helps to control the operating temperature.

[0038] In another implementation scheme, such as Figure 2 As shown, an insulation layer 2301 is fixedly sleeved inside the mounting groove 23, and an electric heating layer 2302 is fixedly sleeved inside the mounting groove 23. The insulation layer 2301 is located outside the electric heating layer 2302, and the electric heating layer 2302 corresponds to the position of the scraper 20.

[0039] The insulation layer 2301 reduces the loss of temperature applied to the electric heating layer 2302, ensuring that the heating effect of the electric heating layer 2302 is applied to the inner wall of the cylinder 1, which facilitates structural adjustment and use, increases the use effect, and facilitates the electric heating layer 2302 to heat the inner side of the scraper 20, ensuring that the temperature of the dyeing solution is maintained within the operating range.

[0040] In another implementation scheme, such as Figure 2 As shown, a drive gear 19 meshes with the outer side of the driven gear ring 12. A transmission gearbox 17 is connected to one side of the drive gear 19. A reduction drive motor 18 is connected to the input end of the transmission gearbox 17. Both the reduction drive motor 18 and the transmission gearbox 17 are fixedly mounted on the top of the base 5.

[0041] After the reduction drive motor 18 starts, it drives the transmission gearbox 17 to drive the transmission. After the transmission gearbox 17 changes speed, it drives the drive gear 19 to rotate. The drive gear 19 drives the driven gear ring 12 to rotate, so that the cylinder 1 can be rotated, which increases the relative stability of the structure and facilitates the transmission operation of the structure.

[0042] In another implementation scheme, such as Figure 2As shown, the rotary sealing structure 6 includes a guide pipe 601 and a concave circular frame 607. The guide pipe 601 is fixedly inserted through the cylinder 1 and communicates with the interior of the cylinder 1. The guide pipe 601 is evenly distributed circumferentially inside the cylinder 1. A transverse support ring 602 is fixedly sleeved on the outer side of the guide pipe 601. Sealing bearings 603 are sleeved on the inner sides of both sides of the transverse support ring 602. The other side of the sealing bearings 603 is sleeved on the inner wall of the concave circular frame 607. The concave circular frame 607 is a concave-top rectangle. Sealing cones 604 are sleeved on the inner sides of both sides of the transverse support ring 602. Sealing cones 604 are fixedly installed on the concave circular frame 607. On the inner wall, sealing cones 605 are fixedly sleeved on the outer sides of both sides of the transverse support ring 602. Sealing cones 605 are movably sleeved on the inner wall of the concave circular frame 607. Rotary seals 606 are embedded in the inner sides of both sides of the transverse support ring 602. The outer side of the rotary seals 606 is movably installed with the inner side of the concave circular frame 607. External seals 608 are provided on the opposite sides of the sealing bearing 603. The opposite side of the external seals 608 is fixedly installed on the side wall of the concave circular frame 607. The outer side of the external seals 608 is in movable contact with the transverse support ring 602. The specifications of the rotary seal structure 7 and the rotary seal structure 6 are the same.

[0043] When the cylinder 1 rotates, it drives the guide pipe 601 and the horizontal support ring 602 to rotate. One side of the horizontal support ring 602 is rotated and supported by the second sealing bearing 603 and the concave top position of the concave circular frame 607. When the horizontal support ring 602 rotates, it is sealed internally by the first sealing cone 604 and the second sealing cone 605. The rotary seal 606 provides a rotary seal on the opposite sides of the horizontal support ring 602 and the concave circular frame 607, while the outer seal 608 reduces the entry of external objects into the concave circular frame 607. The operation position of 7 reduces the impact of the external environment on the internal hardware and ensures the sealing effect. As it rotates, the water outlet pipe 8 inputs water flow to the opposite side of the concave circular frame 607 and the horizontal support ring 602. At this time, the fluid is limited by the horizontal support ring 602 and the concave circular frame 607 and then connects to the inside of the cylinder 1 through the guide pipe 601. This ensures that the fluid can pass through the cylinder 1 while it is rotating, which facilitates auxiliary operations, stabilizes rotation and fluid balance, and provides space for the fluid to enter and exit, thus increasing the effectiveness of use.

[0044] In another implementation scheme, such as Figure 2 As shown, the top of the outlet pipe 8 is connected to the addition pipe 9, and a valve is installed inside the addition pipe 9. The heat-resistant water pump 30 and the closed liquid filter 31 are both fixedly installed on the top of the base 5. The extraction pipe 32 is connected to the bottom of the rotary sealing structure 6. The discharge pipe 33 is movably installed with a discharge valve 34 inside. The position of the rotary sealing structure 6 corresponds to the position of the scraper 20. Both the outlet pipe 8 and the extraction pipe 32 are equipped with one-way valves.

[0045] When dyeing is being performed inside the cylinder 1, the heat-resistant water pump 30 starts, creating negative pressure inside the sealed liquid filter 31. Liquid is drawn out from inside the cylinder 1 through the extraction pipe 32, and after passing through the sealed liquid filter 31 to filter out wool fibers and impurities, ensuring reduced temperature and preventing clogging during the return dyeing process, the liquid is pumped out by the heat-resistant water pump 30 and output to the outlet pipe 8. The outlet pipe 8 then guides the liquid flow to the top of the rotary sealing structure 6, and through the guide pipe 601 inside the rotary sealing structure 6, it flows to the top of the inner cavity of the cylinder 1 for spraying. Meanwhile, the extraction pipe 32... 2. The liquid inside the cylinder 1 is discharged through the guide pipe 601 at the bottom of the rotary sealing structure 6. The liquid is circulated under gravity, which increases the stability of the dyeing solution and allows operation between rotation and circulation, indirectly increasing efficiency. The extraction pipe 32 is connected to the inside of the concave circular frame 607. In addition, a baffle can be set on the opposite side of the guide pipe 601 to separate the opposite side of the horizontal support ring 602 and the guide pipe 601. This makes it easier for the guide pipe 601 and the horizontal support ring 602 to rotate with the cylinder 1. The baffle reduces the turbulence of the liquid and facilitates the flow direction of the fluid.

[0046] In another implementation scheme, such as Figure 2 As shown, the exhaust pipe 13 is connected to the bottom of the rotary sealing structure 7, the top of the intake pipe 11 is connected to the pressure relief pipe 10, the heat-resistant air pump 14 and the sealed condenser box 15 are both fixedly installed on the top of the base 5, the intake pipe 11 and the exhaust pipe 13 are both equipped with one-way valves, and the pressure relief pipe 10 is equipped with a pressure relief valve.

[0047] When the inner side of the cylinder 1 is being dried, the heat-resistant air pump 14 is started to extract the gas from the rotary sealing structure 7 and the top of the inner cavity of the cylinder 1 through the suction pipe 11, and output it to the inside of the sealed condenser box 15 to condense the steam. The sealed condenser box 15 is a sealed box structure with a condenser inside. The heat dissipation mechanism of the condenser is externally hung on the outside of the sealed condenser box 15 to ensure that the inside of the sealed condenser box 15 maintains its sealing and condensation functions. The condensed liquid is discharged through the drain valve 16. The condensation gradually reduces the moisture content inside the cylinder 1 during drying, and the dried gas is circulated back to the rotary sealing structure 7 and the inside of the cylinder 1 through the exhaust pipe 13. During the drying operation, gas is discharged from the top and introduced from the bottom to achieve airflow circulation, which facilitates the reduction of moisture content in the gas, helps with gradual drying, and facilitates the operation.
