The L-shaped frame is fixedly connected to the adjacent U-shaped plate.

[0018] A method of using a disperse dyeing machine for recycled polyester fibers includes:

[0019] S1: First, add an appropriate amount of dye to the inner cavity of the dyeing tank, and slide the take-up roller and unwind roller to the outer periphery of the spline roller respectively. Pass the tape on the unwind roller over the support rod and wrap it around the take-up roller. At this time, the recycled polyester fiber fabric passes through the two rotating rollers and support roller A in sequence, and passes through the surface of several guide rollers in the inner cavity of the dyeing tank. Then it can pass through the fixed roller and the extrusion roller, and connect to the outer receiving and winding device through the inner cavity of the drying box.

[0020] S2: When the recycled polyester fiber fabric moves, the bottom of the fabric contacts the adhesive side of the tape. As the fabric passes through the tape, lint or dust on the fabric surface can be cleaned. During the cleaning process, when the straight rod rotates, the rotating gear fixed on the transmission gear can rotate. During the rotation of the rotating gear, the fixed shaft A can rotate, which in turn can rotate the spline roller fixed on the adjacent fixed shaft A. Under the drive of the synchronous pulley and synchronous belt, the fixed shaft B can rotate, which in turn can rotate the adjacent spline roller fixed on the fixed shaft B. The tape with lint and dust adhering to it can be wound up, thereby improving the effect of lint and dust treatment on the recycled polyester fiber fabric.

[0021] S3: As the take-up roller continuously rewinds, the diameter of the waste tape roll gradually increases, which allows the arc-shaped block to move to one side. The insulating block can be moved to one side by the bent rod fixed on the arc-shaped block. As the insulating block moves to one side, the conductive block can contact the two electrode plates, which can light up the adjacent alarm lights to remind the staff to replace the take-up roller.

[0022] S4: When the take-up roller needs to be replaced, the T-shaped rod can be pulled forward so that the end of the T-shaped rod is away from the inner cavity of the adjacent blind hole. Then, the connecting plate is rotated, which allows the movable rod fixed on the connecting plate to rotate. The driving bevel gear fixed on the movable rod can rotate the two driven bevel gears meshing with it. The threaded rod fixed on the driven bevel gear can move the threaded sleeves threaded on the adjacent threaded rods to the opposite side. This allows the L-shaped stop fixed on the threaded sleeve to retract into the inner cavity of the circular groove. Then, the take-up roller can be slid off the outer circumference of the spline roller for easy replacement.

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

[0024] 1. When removing impurities from recycled polyester fiber fabric, the lint removal component can be used to remove lint and dust from the fabric surface by using the tape on the unwinding roller. The tape can be continuously wound up after use by the rotation of the fixed shaft B, which improves the effect of removing lint and dust from the fabric and is beneficial to the subsequent dyeing effect of the recycled polyester fiber fabric.

[0025] 2. As the take-up roller continuously winds up, the diameter of the waste tape wound on the take-up roller gradually increases. With the cooperation of the warning component, the arc-shaped block can be moved to one side, which in turn can move the insulating plate fixed on the bent rod to one side, allowing the conductive block to contact the electrode plate, thereby illuminating the alarm light and reminding the staff that it needs to be replaced to avoid affecting the impurity removal process.

[0026] 3. When the take-up roller needs to be replaced, with the cooperation of the disassembly assembly, the threaded rod fixed on the adjacent driven bevel gear can be rotated when the two driven bevel gears rotate. This allows the threaded sleeve connected to the adjacent threaded rod to move to the opposite side, thereby allowing the L-shaped stop block to retract into the inner cavity of the circular groove, making it convenient to remove and replace the take-up roller and reducing the disassembly effort for the workers.

[0058] Reference Figures 1-10A disperse dyeing machine for recycled polyester fibers includes a processing table 1 and a dyeing tank 3 located on the other side of the processing table 1. (An ultrasonic generator is installed inside the dyeing tank 3, reducing the amount of disperse dye used during the dyeing process by 22% and reducing wastewater discharge by 12,000 tons annually.) A drying rack 5 is installed on the other side of the dyeing tank 3, and a drying box 6 is installed at the top center of the drying rack 5. (The drying box 6 is existing technology, and its working principle will not be described in detail here; it can dry the dyed fabric.) The top of the drying rack 5 is also equipped with [unclear text - possibly related to a specific product or service]. There is a guide frame 10, and the inner cavity of the dyeing tank 3 is provided with several guide rollers 4. A support roller A2 is fixedly installed at the middle position of the top of the processing table 1. U-shaped plates 80 are fixedly installed on both sides of the top of the processing table 1. Rotating rollers 30 are provided in the inner cavity of each U-shaped plate 80, and straight rods 90 are provided through the inner cavity of each rotating roller 30. The front end of the straight rod 90 is rotatably connected to the adjacent U-shaped plate 80, and the rear end of the straight rod 90 is movably inserted through the adjacent U-shaped plate 80. Vertical plates 20 are fixedly installed on both sides of the top of the processing table 1.

[0059] The lint removal components 7 are respectively installed on the front side of the upright plate 20 (the lint removal components 7 are provided in two sets to treat the bottom and top surfaces of the fabric).

[0060] Disassembly components 8 are respectively installed on the down removal components 7;

[0061] Warning components 9 are respectively installed on both sides of the support roller A2.

[0062] Reference Figure 2 , Figure 3 and Figure 8 The delinting assembly 7 includes a transmission gear 71 fixedly sleeved on the outer periphery of the straight rod 90 near the rear end and a rotating gear 72 meshing on one side of the transmission gear 71. A fixed shaft A73 is provided through the center of the front side of the rotating gear 72. A fixed shaft B74 is provided on the other side of the fixed shaft A73 near the bottom. The front ends of the fixed shaft B74 and the fixed shaft A73 movably pass through the front side of the vertical plate 20 and are both fixedly installed with spline rollers 75. A take-up roller 76 and an unwind roller 78 are slidably connected to the outer periphery of the spline roller 75 respectively. (The take-up roller 76 can take up the waste tape, and the unwind roller 78 has tape wrapped around its outer periphery.) A support rod 77 is provided above the top of the take-up roller 76.

[0063] Specifically, when removing impurities from recycled polyester fiber fabric, with the cooperation of the delinting component block 7, the tape on the unwinding roller block 78 can remove lint and dust adhering to the fabric surface. Furthermore, the rotation of the fixed shaft block B 74 can continuously rewind the used tape, improving the effect of removing lint and dust from the fabric and facilitating the subsequent dyeing of the recycled polyester fiber fabric.

[0064] The rear end of the support rod 77 is rotatably connected to a slider 771. A groove 774 is provided on the front side of the upright plate 20 near the other side, and the slider 771 is slidably connected in the inner cavity of the groove 774. A support telescopic rod 772 is fixedly installed at the bottom of the inner cavity of the groove 774. The top end of the support telescopic rod 772 is fixedly connected to the slider 771. A support spring 773 is movably sleeved on the outer periphery of the support telescopic rod 772, and the two ends of the support spring 773 are fixedly connected to the bottom of the inner cavity of the slider 771 and the groove 774, respectively. Synchronous pulleys 731 are fixedly sleeved on the outer periphery of the fixed shaft A73 and the fixed shaft B74 near the rear end, and a synchronous belt 732 is sleeved on the synchronous pulleys 731 together.

[0065] Specifically, by setting the support spring 773 and the support telescopic rod 772, the support rod 77 can be in close contact with the fabric, which is beneficial to the subsequent removal of impurities from the fabric. Furthermore, by setting the synchronous pulley 731 and the synchronous belt 732, the fixed shaft A73 and the fixed shaft 74 can rotate synchronously.

[0066] Reference Figure 1 and Figure 6 The warning component 9 includes an arc-shaped block 91 located on one side of the take-up roller 76 and an L-shaped strip 92 fixedly installed at the bottom of the arc-shaped block 91 near the front and rear sides. A connecting telescopic rod 93 is fixedly installed on one side of each L-shaped strip 92, and a mounting plate 95 is fixedly installed on one end of each connecting telescopic rod 93. A connecting spring 94 is movably sleeved on the outer periphery of each connecting telescopic rod 93, and the top and bottom ends of the connecting spring 94 are fixedly connected to the L-shaped strip 92 and the mounting plate 95, respectively. The mounting plate 95 is fixedly connected to the upright plate 20. A bent rod 96 is fixedly installed at the bottom center of the arc-shaped block 91. A protective shell 99 is fixedly installed at the center of the other side of the mounting plate 95. One end of the bent rod 96 moves through the inner cavity of the protective shell 99 and is fixedly installed with an insulating block. A conductive block 97 is fixedly installed on one side of the insulating block. Two electrode plates 98 are fixedly installed on one side of the inner cavity of the protective shell 99 (the electrode plates 98 are electrically connected to the positive and negative poles of the external power supply, and the conductive block 97 is electrically connected to the alarm light). An alarm light is fixedly installed on the front side of the upright plate 20.

[0067] Specifically, as the take-up roller 76 continuously winds up, the diameter of the waste tape wound on the take-up roller 76 gradually increases. With the cooperation of the warning component 9, the arc-shaped block 91 can be moved to one side, which in turn can move the insulating plate fixed on the bent rod 96 to one side, allowing the conductive block 97 to contact the electrode plate 98, thereby illuminating the alarm light and reminding the staff that it needs to be replaced to avoid affecting the impurity removal process.

[0068] Reference Figure 4 , Figure 5 , Figure 9 and Figure 10The disassembly assembly 8 includes a circular groove located near the front end of the inner cavity of the spline roller 75 and a movable rod 81 rotatably connected to the rear side of the inner cavity of the circular groove. The front end of the movable rod 81 movably passes through the front side of the inner cavity of the circular groove and is fixedly installed with a connecting plate 87. A driving bevel gear 82 is fixedly sleeved on the outer periphery of the movable rod 81 near the front end, and driven bevel gears 83 mesh on both sides of the driving bevel gear 82. A threaded rod 85 is fixedly installed on the opposite side of the driven bevel gear 83. (The outer periphery of the threaded rod 85 has opposite external threads with the same thread precision.) A threaded sleeve 84 is threadedly connected to the outer periphery of the threaded rod 85. An L-shaped stop 86 is fixedly installed on the top of the threaded sleeve 84, and the L-shaped stop 86 movably passes through the inner cavity sidewall of the circular groove and extends to the outer periphery of the spline roller 75.

[0069] Specifically, when the take-up roller 76 needs to be replaced, with the cooperation of the disassembly assembly 8, the threaded rod 85 fixed on the adjacent driven bevel gear 83 can rotate when the two driven bevel gears 83 rotate. This allows the threaded sleeve 84 threadedly connected to the adjacent threaded rod 85 to move to the opposite side, thereby allowing the L-shaped stop 86 to retract into the inner cavity of the circular groove, making it convenient to remove and replace the take-up roller 76 and reducing the disassembly effort for the workers.

[0070] Each threaded sleeve 84 has a limiting telescopic rod 841 fixedly installed on one side of the threaded sleeve, and a connecting block 842 is fixedly installed on the opposite end of each limiting telescopic rod 841. The front side of each connecting block 842 is fixedly connected to the front side of the inner cavity of the circular groove. The threaded rod 85 moves through the adjacent connecting block 842 respectively.

[0071] Specifically, by setting the limit telescopic rod 841, the movement of the threaded sleeve 84 can be limited, thereby improving the stability of its movement.

[0072] A T-shaped rod 871 is movably inserted through the front side of the connecting plate 87, and several blind holes 873 are opened on the front side of the spline roller 75. The rear end of the T-shaped rod 871 is movably inserted into the inner cavity of the blind hole 873. A telescopic spring 872 is movably sleeved on the outer periphery of the T-shaped rod 871, and the two ends of the telescopic spring 872 are fixedly connected to the T-shaped rod 871 and the connecting plate 87, respectively.

[0073] Specifically, by setting the T-shaped rod 871 and the telescopic spring 872, the T-shaped rod 871 can be stably inserted into the inner cavity of the blind hole 873, which can limit the position of the connecting plate 87 after rotation.

[0074] A connecting strip 51 is fixedly installed on one side of the drying rack 5 near the front and rear sides. A fixed roller 52 is fixedly installed on the opposite side of the connecting strip 51. A squeezing roller 53 is provided on one side of the fixed roller 52. Sliding blocks 54 are rotatably connected to both ends of the squeezing roller 53. The bottom of the sliding blocks 54 is slidably connected to the connecting strip 51. A squeezing telescopic rod 56 is fixedly installed on one side of the sliding block 54. A fixed block 55 is fixedly installed at one end of the squeezing telescopic rod 56. The bottom of the fixed block 55 is fixedly connected to the connecting strip 51. A squeezing spring 57 is movably sleeved on the outer periphery of the squeezing telescopic rod 56. The two ends of the squeezing spring 57 are fixedly connected to the sliding block 54 and the fixed block 55, respectively.

[0075] Specifically, by setting the compression spring 57 and the compression roller 53 to be in tight contact with the fixed roller 52, excess dye on the fabric surface can be squeezed out, thus avoiding dye waste.

[0076] Each of the rotating rollers 30 is provided with a pressing roller frame 40 at its top. A compression telescopic rod 60 is fixedly installed on the top of the pressing roller frame 40 near the front and rear sides. An L-shaped frame 50 is fixedly installed on the top of two adjacent compression telescopic rods 60. A compression spring 70 is movably sleeved on the outer periphery of each compression telescopic rod 60. The two ends of the compression spring 70 are fixedly connected to the L-shaped frame 50 and the pressing roller frame 40, respectively. The L-shaped frame 50 is fixedly connected to the adjacent U-shaped plate 80.

[0077] Specifically, by setting the compression spring 70, the extrusion roller frame 40 and the rotating roller 30 can be made to come into tight contact, which can flatten the fabric and avoid wrinkles that would affect the subsequent dyeing effect.

[0078] A method of using a disperse dyeing machine for recycled polyester fibers includes:

[0079] S1: First, add an appropriate amount of dye to the inner cavity of the dyeing tank 3, and slide the take-up roller 76 and the unwind roller 78 to the outer periphery of the spline roller 75 respectively. Pass the tape on the unwind roller 78 over the support rod 77 and wrap it around the take-up roller 76. At this time, the recycled polyester fiber fabric passes through the two rotating rollers 30 and the support roller A2 in sequence, and passes through the surface of several guide rollers 4 in the inner cavity of the dyeing tank 3. Then it can pass through the fixed roller 52 and the extrusion roller 53, and connect to the outer receiving and winding device through the inner cavity of the drying box 6.

[0080] S2: When the recycled polyester fiber fabric moves, the bottom of the fabric contacts the adhesive side of the tape. As the fabric passes through the tape, lint or dust on the surface of the fabric can be cleaned. During the cleaning process, when the straight rod 90 rotates, the rotating gear 72 fixed on the transmission gear 71 can rotate. During the rotation of the rotating gear 72, the fixed shaft A73 can rotate, which in turn can rotate the spline roller 75 fixed on the adjacent fixed shaft A73. Under the drive of the synchronous pulley 731 and the synchronous belt 732, the fixed shaft B74 can rotate, which in turn can rotate the adjacent spline roller 75 fixed on the fixed shaft B74. The tape with lint and dust adhering to it can be wound up, thereby improving the effect of lint and dust treatment on the recycled polyester fiber fabric.

[0081] S3: As the take-up roller 76 continuously rewinds, the diameter of the waste tape roll gradually increases, which allows the arc block 91 to move to one side. The insulating block can be moved to one side by the bent rod 96 fixed on the arc block 91. As the insulating block moves to one side, the conductive block 97 can contact the two electrode plates 98, which can light up the adjacent alarm lights to remind the staff to replace the take-up roller 76.

[0082] S4: When the take-up roller 76 needs to be replaced, the T-shaped rod 871 can be pulled forward to move the end of the T-shaped rod 871 away from the inner cavity of the adjacent blind hole 873. Then, the connecting plate 87 can be rotated to rotate the movable rod 81 fixed on the connecting plate 87. The driving bevel gear 82 fixedly sleeved on the movable rod 81 can rotate the two driven bevel gears 83 meshing with it. The threaded rod 85 fixed on the driven bevel gear 83 can move the threaded sleeve 84 threadedly connected to the adjacent threaded rod 85 to the opposite side. This allows the L-shaped stop 86 fixed on the threaded sleeve 84 to retract into the inner cavity of the circular groove. Then, the take-up roller 76 can be slid off the outer periphery of the spline roller 75 for easy replacement of the take-up roller 76.

[0083] In summary, the working principle of this invention is as follows: First, an appropriate amount of dye is added to the inner cavity of the dyeing tank 3, and the take-up roller 76 and the unwind roller 78 are slidably connected to the outer periphery of the spline roller 75. The tape on the unwind roller 78 passes over the support rod 77 and is wound around the take-up roller 76. At this time, the recycled polyester fiber fabric passes through the two rotating rollers 30 and the support roller A2 in sequence, and passes through the surface of several guide rollers 4 in the inner cavity of the dyeing tank 3. Then it can pass through the fixed roller 52 and the extrusion roller 53, and then pass through the inner cavity of the drying box 6 and connect to the external receiving and winding device. When the recycled polyester fiber fabric moves, the bottom of the fabric and the tape are connected. The adhesive side contacts the fabric, cleaning lint and dust from the fabric surface as it passes through the tape. During the cleaning process, the rotation of the straight rod 90 causes the rotating gear 72, which is fixedly mounted on the transmission gear 71, to rotate. The rotation of the rotating gear 72 causes the fixed shaft A73 to rotate, which in turn causes the spline roller 75, fixed to the adjacent fixed shaft A73, to rotate. Driven by the synchronous pulley 731 and the synchronous belt 732, the fixed shaft B74 rotates, which in turn causes the adjacent spline roller 75, fixed to the fixed shaft B74, to rotate, thus cleaning the tape containing lint and dust. The winding process improves the removal of lint and dust from recycled polyester fiber fabrics. As the winding roller 76 continuously winds the fabric, the diameter of the waste tape roll gradually increases, allowing the arc-shaped block 91 to move to one side. The insulating block can then be moved to one side via the bent rod 96 fixed to the arc-shaped block 91. As the insulating block moves to one side, the conductive block 97 contacts the two electrode plates 98, illuminating the adjacent alarm lights and alerting staff to replace the winding roller 76. When the winding roller 76 needs to be replaced, the T-shaped rod 871 can be pulled forward, moving the end of the T-shaped rod 871 away from the surrounding area. In the inner cavity of the adjacent blind hole 873, the connecting plate 87 is rotated, which allows the movable rod 81 fixed on the connecting plate 87 to rotate. The driving bevel gear 82 fixedly sleeved on the movable rod 81 allows the two driven bevel gears 83 meshing with it to rotate. The threaded rod 85 fixed on the driven bevel gear 83 allows the threaded sleeve 84 threadedly connected to the adjacent threaded rod 85 to move to the opposite side. This allows the L-shaped stop 86 fixed on the threaded sleeve 84 to retract into the inner cavity of the circular groove. Then the take-up roller 76 can be slid off the outer periphery of the spline roller 75 for easy replacement of the take-up roller 76.

10. A method of using a disperse dye dyeing machine for recycled polyester fibers according to any one of claims 1-9, characterized in that, Includes the following steps: S1: First, add an appropriate amount of dye to the inner cavity of the dyeing tank (3), and slide the take-up roller (76) and the unwind roller (78) to the outer periphery of the spline roller (75) respectively. Pass the tape on the unwind roller (78) over the support rod (77) and wrap it around the take-up roller (76). At this time, the recycled polyester fiber fabric passes through the two rotating rollers (30) and the support roller A (2) in sequence, and passes through the surface of several guide rollers (4) in the inner cavity of the dyeing tank (3). Then it can pass through the fixed roller (52) and the extrusion roller (53), and connect to the outer receiving and winding device through the inner cavity of the drying box (6). S2: When the recycled polyester fiber fabric moves, the bottom of the fabric contacts the adhesive side of the tape. When the fabric passes through the tape, the lint or dust on the surface of the fabric can be cleaned. During the cleaning process, when the straight rod (90) rotates, the rotating gear (72) fixed on the transmission gear (71) can rotate. During the rotation of the rotating gear (72), the fixed shaft A (73) can rotate, which in turn can rotate the spline roller (75) fixed on the adjacent fixed shaft A (73). Under the transmission of the synchronous wheel (731) and the synchronous belt (732), the fixed shaft B (74) can rotate, which in turn can rotate the adjacent spline roller (75) fixed on the fixed shaft B (74). The tape with lint and dust adhering to it can be wound up, thereby improving the effect of lint and dust treatment on the recycled polyester fiber fabric. S3: As the take-up roller (76) continuously rewinds, the diameter of the waste tape roll gradually increases, which allows the arc block (91) to move to one side. The insulating block can be moved to one side by the connecting line of the bent rod (96) fixed on the arc block (91). As the insulating block moves to one side continuously, the conductive block (97) can contact the two electrode plates (98), which can make the adjacent alarm lights light up and remind the staff to replace the take-up roller (76). S4: When the take-up roller (76) needs to be replaced, the T-shaped rod (871) can be pulled forward so that the end of the T-shaped rod (871) is away from the inner cavity of the adjacent blind hole (873). Then, the connecting plate (87) is rotated so that the movable rod (81) fixed on the connecting plate (87) can be rotated. The active bevel gear (82) fixed on the movable rod (81) can rotate the two driven bevel gears (83) meshing with it. The threaded rod (85) fixed on the driven bevel gear (83) can move the threaded sleeve (84) threadedly connected to the adjacent threaded rod (85) to the opposite side. Then, the L-shaped stop (86) fixed on the threaded sleeve (84) can be retracted into the inner cavity of the circular groove. Then the take-up roller (76) can be slid off the outer periphery of the spline roller (75) for easy replacement of the take-up roller (76).
