Description

Technical Field

[0001] The utility model relates to the technical field of dyeing machines, in particular to a cloth outlet mechanism of a low-bath-ratio overflow dyeing machine. Background Technique

[0002] At present, the dyeing process in the knitting industry still mainly uses overflow machines. High-bath-ratio overflow machines require a larger amount of dyeing auxiliaries, water, electricity, and steam. They not only have high energy consumption and high production costs, but also cost more money to treat a large amount of printing and dyeing wastewater, which also causes great damage to the ecological environment. Therefore, existing technologies mostly use low-bath-ratio overflow dyeing machines with a low dyeing bath ratio, small horsepower, high output, and high dye liquor circulation, which can achieve excellent leveling effects. Low-bath-ratio overflow dyeing machines are currently widely used dyeing equipment in printing and dyeing factories, mainly used for the pretreatment and dyeing of various knitted grey fabrics such as pure cotton, pure polyester, polyester-cotton, and polyester, and can also be used for processing such as scouring, bleaching, pre-shrinking, and alkali weight reduction of fabrics.

[0003] Chinese Patent (authorized publication number: CN 218147327 U, authorized publication date: December 27, 2022) proposed a cloth outlet device for a low-bath-ratio overflow dyeing machine. In this patent, the rotation of the guide cloth wheel is driven by starting the rotating motor, and the rotation of the guide cloth wheel drives the cloth to be exported from the overflow dyeing machine and moved into the storage basket. The water squeezing assembly squeezes the cloth exported from the overflow dyeing machine, and squeezes the dye liquor in the cloth into the collection box for collection, thereby reducing the probability that the dye liquor in the cloth falls in the environment and pollutes the working environment.

[0004] After the above-mentioned patent squeezes the cloth through the water squeezing assembly, the cloth will have unexpected wrinkles. However, the cloth outlet structure of the above-mentioned patent does not have a cloth outlet flattening structure for the squeezed cloth, which reduces the subsequent cloth receiving effect. Therefore, we propose a cloth outlet mechanism for a low-bath-ratio overflow dyeing machine. Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution: a fabric outlet mechanism of a low liquor ratio overflow dyeing machine, including brackets 1 on the left and right sides. A swing shaft 13 is rotatably penetrated through the bracket 1. A swing frame 5 is fixedly connected to the swing shaft 13. An adjusting frame 6 is arranged at the bottom of the swing frame 5. A height adjusting component is connected between the swing frame 5 and the adjusting frame 6. A rotating roller 8 is rotatably installed on the adjusting frame 6. A first slider 23 is slidably assembled on the adjusting frame 6. A flattening roller 7 is rotatably installed between the two first sliders 23. Positive spiral friction ridges 11 are arranged on the left side of the outer surface of the flattening roller 7, and reverse spiral friction ridges 12 are arranged on the right side of the outer surface of the flattening roller 7. A gap adjusting component for adjusting the gap of the flattening roller 7 is installed on the left adjusting frame 6, and a driving component for driving the flattening roller 7 to rotate is installed on the left swing frame 5.

[0029] The water-squeezed fabric enters between the flattening roller 7 and the rotating roller 8. The distance between the flattening roller 7 and the rotating roller 8 can be adjusted through the gap adjustment component. The clamped fabric can be driven and conveyed through the driving component. The provided height adjustment component can adjust the length between the adjustment frame 6 and the swing frame 5. On the left side of the flattening roller 7, there are positive spiral friction ridges 11 and reverse spiral friction ridges 12. During the conveying process of the flattening roller 7, the positive spiral friction ridges 11 convey and flatten the fabric to the left through friction, and the reverse spiral friction ridges 12 convey and flatten the fabric to the right through friction. Thus, the fabric can be flattened when collecting the fabric, effectively improving the subsequent fabric collection effect.

[0030] The height adjustment component includes a second slider 27. The second slider 27 is slidably assembled on the swing frame 5. A plurality of slide rods 30 are fixedly connected to the second slider 27. The slide rods 30 slidably pass through the swing frame 5, and the bottom of the slide rods 30 is fixedly connected to the upper end surface of the adjustment frame 6. A first lead screw 10 is rotatably installed on the left swing frame 6. The first lead screw 10 is threadedly passed through the second slider 27. The top end of the first lead screw 10 is fixedly connected to a first bevel gear 28. A drive shaft is rotatably installed on the swing frame 6. One end of the drive shaft is fixedly connected to a second bevel gear 29. The second bevel gear 29 meshes with the first bevel gear 28. The other end of the drive shaft is fixedly connected to a first handwheel 9.

[0031] When using the height adjustment component, rotate the first handwheel 9. The first handwheel 9 drives the second bevel gear 29 to rotate. Since the second bevel gear 29 meshes with the first bevel gear 28, it will drive the first lead screw 10 to rotate. When the first lead screw 10 rotates, it will drive the second slider 27 to move up and down. When the second slider 27 moves up and down, it will drive the adjustment frame 6 to move up and down through the slide rods 30. Thus, the fabric output height of this fabric output mechanism can be adjusted.

[0032] The gap adjustment component includes two groups of second lead screws 20. The second lead screws 20 are rotatably installed on the adjustment frame 6. The second lead screws 20 are threadedly passed through the first slider 23. A gear 21 is fixedly sleeved on the outer surface of the second lead screws 20. The two groups of gears 21 mesh. One end of the second lead screw 20 in one of the groups is fixedly connected to a second handwheel 22.

[0033] Since the two groups of gears 21 mesh, when rotating the second handwheel 22, it will drive the two groups of second lead screws 20 to rotate. When the second lead screws 20 rotate, they drive the first slider 23 to move. When the first slider 23 moves, it will drive the flattening roller 7 to move up and down. Thus, the distance between the flattening roller 7 and the rotating roller 8 can be adjusted to adapt to the clamping and conveying of fabrics with different thicknesses.

[0034] A fixed frame 14 is fixedly connected to the right bracket 1. A swing motor 4 is fixedly installed on the fixed frame 14. The output end of the swing motor 4 is fixedly connected to the right swing shaft 13.

[0035] When the swing motor 4 works, it will drive the swing frame 5 and the adjustment frame 6 to swing back and forth, facilitating the stacking of fabrics.

[0036] A number of guide rollers 3 are rotatably installed between the brackets 1 on the left and right sides.

[0037] The drive assembly includes a drive motor 2, which is fixedly installed on the swing frame 5 on the left side. The output end of the drive motor 2 is fixedly connected to a first connecting cylinder 26. A first telescopic plate 15 is slidably inserted through the first connecting cylinder 26. A first pulling block 25 is fixedly connected to the adjustment frame 6. A transmission shaft 16 is rotatably inserted through the first pulling block 25. The bottom of the first telescopic plate 15 is fixedly connected to the transmission shaft 16.

[0038] A second pulling block 31 is fixedly connected to the first slider 23 on the left side. A second telescopic plate 18 is rotatably installed on the second pulling block 31. The bottom of the transmission shaft 16 is fixedly connected to a second connecting cylinder 17. The second telescopic plate 18 is slidably assembled on the second connecting cylinder 17. An active bevel gear 19 is fixedly sleeved on the outer surface of the second telescopic plate 18. The end of the rotating shaft of the flattening roller 7 is fixedly connected to a driven bevel gear 24. The driven bevel gear 24 meshes with the active bevel gear 19.

[0039] When the adjustment frame 6 moves up and down, the first pulling block 25 will pull the first telescopic plate 15 to slide up and down along the inside of the first connecting cylinder 26, thereby compensating for the length of the transmission structure of the flattening roller 7 when the adjustment frame 6 moves up and down. When the first slider 23 moves up and down, the second pulling block 31 will pull the second telescopic plate 18 to slide up and down along the inside of the second connecting cylinder 17, thereby compensating for the length of its transmission structure when the gap of the flattening roller 7 is adjusted. When the drive motor 2 starts, it will drive the first connecting cylinder 26, the first telescopic plate 15, the transmission shaft 16, the second telescopic plate 18, the second connecting cylinder 17, the driven bevel gear 24 and the active bevel gear 19 to rotate, realizing the rotational drive of the flattening roller 7.

[0040] The outer surfaces of both the first handwheel 9 and the second handwheel 22 are provided with anti-slip patterns.

[0041] The bracket 1 is fixedly connected with a mounting plate, and a number of mounting holes are opened on the mounting plate, facilitating the fixing of the bracket 1.

[0042] A control panel is installed on the bracket 1, facilitating the control of the swing motor 4 and the drive motor 2.

[0043] Working principle: When in use, rotate the first handwheel 9. The first handwheel 9 drives the second bevel gear 29 to rotate. Since the second bevel gear 29 meshes with the first bevel gear 28, it further drives the first lead screw 10 to rotate. When the first lead screw 10 rotates, it will drive the second slider 27 to move up and down. When the second slider 27 moves up and down, it will drive the adjusting frame 6 to move up and down through the slide bar 30. When the adjusting frame 6 moves up and down, the first pulling block 25 will pull the first telescopic plate 15 to slide up and down inside the first connecting cylinder 26. Thus, the length compensation of the transmission structure of the flattening roller 7 can be carried out when the adjusting frame 6 moves up and down, and then the cloth output height of this cloth output mechanism can be adjusted first;

[0044] After that, the water-squeezed cloth is fed between the flattening roller 7 and the rotating roller 8. Since the two groups of gears 21 mesh, when the second handwheel 22 is rotated, it will drive the two groups of second lead screws 20 to rotate. When the second lead screws 20 rotate, they drive the first slider 23 to move. When the first slider 23 moves, it will drive the flattening roller 7 to move up and down. When the first slider 23 moves up and down, the second pulling block 31 will pull the second telescopic plate 18 to slide up and down inside the second connecting cylinder 17. Thus, the length compensation of its transmission structure can be carried out when the gap of the flattening roller 7 is adjusted, and then the distance between the flattening roller 7 and the rotating roller 8 can be adjusted to clamp and convey cloths of different thicknesses;

[0045] After that, start the driving motor 2. When the driving motor 2 starts, it will drive the first connecting cylinder 26, the first telescopic plate 15, the transmission shaft 16, the second telescopic plate 18, the second connecting cylinder 17, the driven bevel gear 24 and the driving bevel gear 19 to rotate, so as to drive and convey the clamped cloths of different thicknesses. On the left side of the flattening roller 7, there are positive spiral friction ridges 11 and reverse spiral friction ridges 12. During the conveying process of the flattening roller 7, the positive spiral friction ridges 11 convey and flatten the cloth to the left through friction, and the reverse spiral friction ridges 12 convey and flatten the cloth to the right through friction. Thus, the cloth can be flattened during cloth collection, effectively improving the subsequent cloth collection effect.
