Description

Technical Field

[0001] This invention relates to the field of overflow dyeing technology, specifically an overflow dyeing machine for high-grammage fabrics. Background Technology

[0002] In existing overflow dyeing machines, especially when dyeing high-grammage fabrics (such as ultra-high-grammage nonwovens), operators need to manually thread the fabric into the machine. The conventional method involves first feeding one end of the fabric into the cylinder through the operating port, guiding it around the guide rollers and into the nozzle, then out through the fabric tube. Finally, a tool is needed to guide this end of the fabric back from the storage trough area to the operating port for sewing with the other end, forming a closed loop. However, this threading process is entirely manual, cumbersome, and time-consuming. Because high-grammage fabrics are dense, thick, and stiff, they experience significant resistance when bending and passing through narrow pipes. Operators often need to attempt repeatedly to accurately guide the fabric, resulting in high labor intensity and a risk of fabric edge deformation or damage due to improper pulling. Furthermore, when internal components such as nozzles need replacement or maintenance, the existing traction structure is difficult to quickly reposition or disassemble, further increasing downtime for equipment maintenance. Therefore, how to simplify the fabric feeding operation in the overflow dyeing machine, improve the efficiency of feeding high-gram-weight fabrics onto the machine, and facilitate the maintenance of subsequent components are urgent problems to be solved.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a traction mechanism, the operator only needs to quickly and firmly fix one end of the fabric to the second docking block with a strap, and install the first docking block on the rotating frame. The fabric will then be automatically driven by a motor to pass over the guide wheel and move along a predetermined track. When the rotating frame reaches a designated position (such as contact with the T-block), the first docking block will automatically separate from the rotating frame. At this point, the operator only needs to pull the traction rope to easily guide the fabric smoothly through the nozzle and the fabric tube via the second docking block until the other end of the fabric returns to the operating port. The entire fabric threading process achieves a highly efficient combination of mechanically assisted guidance and rapid manual traction, greatly simplifying the complex steps of traditional manual fabric threading. It is especially suitable for high-grammage fabrics with stiff texture and high bending resistance, effectively reducing operational difficulty and labor intensity, avoiding fabric damage due to repeated pulling, and significantly improving machine preparation efficiency.

[0016] 2. By setting up a docking mechanism, when the nozzle needs to be replaced or maintained, the second threaded rod can be rotated by the third motor, causing the displacement block to move and the T-shaped block to rotate and move aside, thus providing an unobstructed movement path for the rotating frame. The operator can move the rotating frame from above the nozzle to the operating port, and then easily separate the first docking block and the second docking block, completely detaching the traction rope from the nozzle, facilitating quick disassembly and replacement of the nozzle. This design not only solves the problem of the traction structure obstructing nozzle maintenance in existing technologies, but also makes the fixing and separation of the first and second docking blocks more reliable and faster, further shortening equipment downtime for maintenance and improving the flexibility and convenience of equipment use and maintenance.

[0023] Please refer to this carefully. Figures 2 to 8 The traction mechanism 7 includes a rotating frame 701, which is rotatably connected to one side of the guide roller 6. A first spur gear 702 is fixedly connected to the outer wall of one side of the rotating frame 701. A second spur gear 703 is connected to the output end of the second motor 15. The first spur gear 702 and the second spur gear 703 are in contact. A first docking block 704 is installed on the outer wall of the rotating frame 701. A second docking block 705 is provided at the bottom end of the first docking block 704. The top end of the first docking block 704 and the bottom end of the second docking block 705 are fixedly connected to the two ends of the traction rope 706. The traction rope 706 passes through the through-tube. 3 and nozzle 4, the first docking block 704 and the second docking block 705 are fixedly connected by the docking mechanism 8. The traction mechanism 7 also includes a connecting block 707, which is fixedly connected to the outer wall of the first docking block 704. The outer wall of the connecting block 707 has a fixing groove 708. The outer wall of the rotating frame 701 has a connecting groove 709. A fixing block 710 extending into the inner cavity of the connecting groove 709 is slidably connected inside the rotating frame 701. A first spring 711 is connected between the fixing block 710 and the rotating frame 701. A rotating spring 711 is rotatably connected inside the rotating frame 701 at the top of the fixing block 710. A third spur gear 712 is fixedly connected to one end of a fourth spur gear 713. A rack 714 is slidably connected to the outer wall of the fourth spur gear 713 inside the rotating frame 701. The rack 714 extends out of the rotating frame 701. A T-shaped block 715 is provided in the inner cavity of the cylinder 1 above the nozzle 4. The traction mechanism 7 also includes a strap 716, which is fixedly connected to the outer wall of the second docking block 705. A slot 717 is provided on the outer wall of the strap 716. A sliding groove 718 is provided inside the second docking block 705, and an insert 7 is slidably connected to the inner wall of the sliding groove 718. 19. The insert block 719 extends into a second mating block 705. The interior of the second mating block 705 is rotatably connected to a first threaded rod 720 extending into the interior of the insert block 719. One end of the first threaded rod 720 is fixedly connected to a rotating block 721. The interior of the insert block 719 is slidably connected to a pressing rod 722 extending into the inner cavity of the slide groove 718. The interior of the insert block 719 is slidably connected to a locking block 723 located at one end of the pressing rod 722. The outer wall of the locking block 723 is provided with an inclined groove 725. The inner wall of the inclined groove 725 is slidably connected to a sliding rod 724. The sliding rod 724 is fixedly connected to one end of the pressing rod 722.

[0024] In this embodiment: the bottom end of the first docking block 704 is fitted with a second docking block 705. When the fabric is placed into the cylinder 1, one end of the fabric is moved to the outer wall of the second docking block 705, and the binding strap 716 is moved. The binding strap 716 presses one end of the fabric onto the second docking block 705. Then, the insert block 719 is inserted into the slot 717 to position the binding strap 716. After that, the rotating block 721 is rotated, which drives the first threaded rod 720 to rotate. The rotation of the first threaded rod 720 drives the insert block 719 to move. The insert block 719 slides in the slide groove 718. When squeezed... When rod 722 contacts the slide groove 718, the pressing rod 722 is displaced relative to the insert block 719 due to the force applied. The displacement of the pressing rod 722 causes the slide rod 724 to move. The slide rod 724 slides in the inclined groove 725, causing the locking block 723 to move. The locking block 723 moves out of the insert block 719. At this time, the insert block 719 continues to move until the locking block 723 presses the binding strap 716 tightly onto the second docking block 705, thus fixing the binding strap 716 and fixing one end of the fabric to the outer wall of the second docking block 705.

[0025] After the above operations are completed, the connecting block 707 on the first docking block 704 is inserted into the connecting groove 709. At this time, the fixing block 710 is engaged into the fixing groove 708 by the elastic force of the first spring 711, fixing the connecting block 707 in the connecting groove 709, thereby fixing the first docking block 704 onto the rotating frame 701. Then, the second motor 15 is started. The second motor 15 drives the second spur gear 703 to rotate. The rotation of the second spur gear 703 drives the first spur gear 702 to rotate. The rotation of the first spur gear 702 drives the rotating frame 701 to rotate. The rotation of the rotating frame 701 causes the first docking block 704 and the second docking block 705 to move. The movement of the second docking block 705 causes one end of the fabric to move synchronously. The fabric is moved over the guide wheel 6 until the rotating frame 701 contacts the T-block 715. At this time, the T-block 715 contacts the rack 714, pushing the rack 714 to move. The movement of the rack 714 drives the fourth spur gear 713 to rotate. The rotation of the fourth spur gear 713 drives the third spur gear 712 to rotate. The rotation of the third spur gear 712 drives the fixed block 710 to move. The fixed block 710 moves out of the fixed groove 708, releasing the fixation of the first docking block 704. At this time, the first docking block 704 separates from the rotating frame 701. The operator pulls the traction rope 706 through the second docking block 705 to drive the fabric through the nozzle 4 and the fabric tube 3 until one end of the fabric moves back to the operating port 2.

[0026] After completion, rotate the rotating block 721 to reset the displacement of the insert block 719, manually push the locking block 723 to move it into the interior of the insert block 719, move the binding strap 716 out of the insert block 719, loosen one end of the fabric, and then sew the two ends of the fabric together to completely place the closed loop of fabric into the cylinder 1. When the first docking block 704 and the second docking block 705 are not in use, fix the first docking block 704 and the second docking block 705 on the rotating frame 701, and then rotate the rotating frame 701 to move the first docking block 704 and the second docking block 705 above the guide roller 6 to prevent the first docking block 704 and the second docking block 705 from contacting the fabric during the fabric movement.

[0027] Please refer to this carefully. Figures 7 to 10 The docking mechanism 8 includes a mounting groove 801, which is located at the bottom of the first docking block 704. The inner wall of the mounting groove 801 has symmetrically formed limiting grooves 802. A mounting block 803 is fixedly connected to the top of the second docking block 705. Limiting blocks 804 are symmetrically slidably connected inside the mounting block 803. A second spring 805 connects between the two limiting blocks 804. A reinforcing plate 806 is slidably connected inside the mounting block 803 below the limiting blocks 804. A third spring 807 connects the reinforcing plate 806 to the mounting block 803. The reinforcing plate 806 extends into the inner cavity of the sliding groove 718. A positioning groove 80 is formed at one end of the outer wall of the mounting block 803. 8. A positioning rod 809 is slidably connected inside the connecting block 707. One end of the positioning rod 809 extends to the inner wall of the mounting groove 801, and the other end of the positioning rod 809 extends out of the connecting block 707. A support seat 810 is fixedly connected to the inner wall of the cylinder body 1. A fifth spur gear 811 is rotatably connected inside the support seat 810. The fifth spur gear 811 is fixedly connected to the T-shaped block 715. A displacement block 812 is slidably connected inside the support seat 810 to the outer wall of the fifth spur gear 811. A third motor 814 is installed on the outer wall of the cylinder body 1. A second threaded rod 813 is connected to the output end of the third motor 814. The second threaded rod 813 extends into the interior of the displacement block 812.

[0028] In this embodiment: when the first docking block 704 and the second docking block 705 are connected, the mounting block 803 is inserted into the mounting groove 801, and the limiting block 804 is engaged into the limiting groove 802 by the elastic force of the second spring 805, thus performing a positioning operation between the first docking block 704 and the second docking block 705; when the first docking block 704 and the second docking block 705 are separated, the second docking block 705 is pushed away from the first docking block 704 to move, at which time the limiting block 804 is displaced out of the limiting groove 802 by force, thereby displacing the mounting block 803 out of the mounting groove 801.

[0029] When the first docking block 704 is fixed on the rotating frame 701, the connecting block 707 is inserted into the connecting groove 709, the positioning rod 809 contacts the inner wall of the connecting groove 709, and the positioning rod 809 is displaced by force and inserted into the positioning groove 808, fixing the mounting block 803 in the mounting groove 801, thus completing the fixation between the first docking block 704 and the second docking block 705; when the strap 716 fixes one end of the fabric to the second docking block 705, the insert block 719 is displaced and contacts the reinforcing plate 806, pushing the reinforcing plate 806 to move, and the reinforcing plate 806 moves between the two limiting blocks 804, fixing the limiting blocks 804, thereby fixing the first docking block 704 and the second docking block 705; when the first docking block 704 and the second docking block 705 are fixed on the rotating frame 701, and one end of the fabric is also fixed to the second docking block 705, it prevents the first docking block 704 and the second docking block 705 from loosening and separating.

[0030] When nozzle 4 needs to be replaced, the third motor 814 is started. The operation of the third motor 814 drives the second threaded rod 813 to rotate. The rotation of the second threaded rod 813 drives the displacement block 812 to move. The displacement of the displacement block 812 drives the fifth spur gear 811 to rotate. The rotation of the fifth spur gear 811 drives the T-shaped block 715 to rotate, moving the T-shaped block 715 away from the moving path of the rotating frame 701. Then, the rotating frame 701 is rotated so that it passes over the nozzle 4 and moves to the operating port 2. At this time, the operator removes the first docking block 704 from the rotating frame 701 and separates the first docking block 704 and the second docking block 705. At this time, the nozzle 4 can be disassembled and replaced.

[0031] Please refer to this carefully. Figures 2 to 8 The outer wall of the insert 719 fits against the inner wall of the slot 717. The outer wall of the insert 719 has a first threaded hole that matches the first threaded rod 720. The outer wall of the slide rod 724 fits against the inner wall of the inclined groove 725.

[0032] In this embodiment: the strap 716 presses one end of the fabric onto the second mating block 705, then the insert block 719 is inserted into the slot 717 to position the strap 716. Next, the rotating block 721 is rotated, causing the first threaded rod 720 to rotate. The first threaded rod 720 rotates, causing the insert block 719 to move. The insert block 719 slides within the sliding groove 718. When the pressing rod 722 contacts the sliding groove 718, the pressing rod 722 is subjected to force and displaces relative to the insert block 719. The displacement of the pressing rod 722 causes the sliding rod 724 to move. The sliding rod 724 slides within the inclined groove 725, causing the locking block 723 to move. The locking block 723 moves out of the insert block 719, and the insert block 719 continues to move until the locking block 723 presses the strap 716 onto the second mating block 705, thus fixing the strap 716.
