Description

Technical Field

[0001] This utility model relates to the field of polyester filament dyeing technology, and more specifically, to an environmentally friendly polyester filament dyeing device. Background Technology

[0002] Polyester dyeing is the process of dyeing polyester fibers (also known as polyester fiber) to the desired color. Polyester yarn has advantages such as high temperature resistance, abrasion resistance, and high strength, and is widely used in fabrics, textiles, yarns and other fields. Polyester is excellent and durable, and is loved by people. Especially with the rapid development of the social economy, the use of polyester yarns of various colors is becoming more and more widespread.

[0003] Utility model publication CN215628690U discloses an environmentally friendly polyester filament dyeing device, belonging to the technical field of textile machinery. Its key technical features include: an unwinding device; a washing tank equipped with several first guide wheels and a first drying device; a dyeing tank adjacent to the washing tank, equipped with several second guide wheels and a first pressure roller and a second pressure roller; and a winding device with a drying mechanism between the dyeing tank and the winding device. The unwinding device is located on one side of the washing tank. After unwinding the polyester filament, it passes it sequentially through the washing tank and the dyeing tank, and then is wound up by the winding device. This application provides a polyester filament dyeing device that provides thorough and uniform dyeing of polyester filament and efficient drying after dyeing, thereby improving dyeing efficiency.

[0004] Regarding the above solution, the applicant believes that although the above solution can effectively achieve a good drying effect and roll up the dyed polyester yarn, the use of ordinary water temperature dyeing agent to dye the polyester yarn not only has a mediocre effect, but may also result in uneven dyeing of the dyed polyester yarn. Furthermore, during the dyeing of polyester yarn, the dyeing agent will release and volatilize some harmful chemicals. If workers are exposed to or inhaled for a long time, these volatilized and released chemicals may easily cause certain harm to their health. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example:

[0027] Please see Figure 1-6 An environmentally friendly polyester filament dyeing device includes a washing tank 1 and a dyeing tank 2. A feeding roller 31 is installed on the upper side of the washing tank 1, and a first holding roller 32 is installed on the inner side of the washing tank 1. A first transfer roller 33 is installed on the upper side of both the washing tank 1 and the dyeing tank 2. The feeding roller 31 feeds the polyester filament to be dyed when rotating, while the first holding roller 32 holds the polyester filament to ensure smooth washing. The first transfer roller 33 transfers the washed polyester filament. A second holding roller 34 is installed on the inner side of the dyeing tank 2, and a second transfer roller 35 and a take-up roller 36 are installed on the upper side of the dyeing tank 2. A washing mechanism 11 is installed on the outer side of the washing tank 1. A drying mechanism 10 is provided on the upper side of the dyeing pool 2, and a processing mechanism 4 is provided on the outer side of the dyeing pool 2. The second pressing roller 34 can press the polyester filaments a second time so that they can be dyed smoothly. Then, the dyed polyester filaments are transported by the second transmission roller 35 and dried by the drying mechanism 10 during the transport process. Finally, they are wound up by the winding roller 36. At the same time, the cleaning mechanism 11 can effectively clean the polyester filaments. The processing mechanism 4 can not only improve the dyeing effect of the polyester filaments, but also treat the harmful gases emitted by the dyeing agent, thereby reducing the possibility of harmful chemical gases causing harm to the health of workers.

[0028] Specifically, the processing mechanism 4 includes a cover plate 41 fixedly connected to the upper side of the dyeing pool 2. A connecting pipe 42 is fixedly connected to the inner side of the cover plate 41. A processing box 43 is provided at the end of the connecting pipe 42 away from the cover plate 41. An air pump 441 and a one-way valve 442 are provided on the outer side of the connecting pipe 42. An installation block 471 is fixedly connected to the outer side of the connecting pipe 42. A first heating plate 472 is fixedly connected to the inner side of the installation block 471. The cover plate 41 can restrict the gas emitted by the dyeing agent, making it difficult for it to drift everywhere. At the same time, the connecting pipe 42 can extract the gas restricted inside the cover plate 41 through the operation of the air pump 441, so that it can smoothly enter the inner side of the processing box 43. The one-way valve 442 can block the gas inside the processing box 43, making it difficult for it to flow back to the inner side of the connecting pipe 42.

[0029] In addition, the first heating plate 472 can heat the harmful gas flowing inside the connecting pipe 42. A connecting block 45 is fixedly connected to the inside of the processing box 43, and a semiconductor cooling chip 46 is provided inside the connecting block 45. An installation groove 481 is opened inside the dyeing pool 2, and a second heating plate 482 is provided inside the installation groove 481. The semiconductor cooling chip 46 can cool down the high-temperature harmful gas entering the processing box 43, causing it to condense, condensing and filtering a large amount of water vapor in the gas, and removing some volatile substances from the gas, thereby effectively reducing the harm caused by chemical gases to people's bodies. At the same time, the second heating plate 482 can heat the dyeing agent inside the dyeing pool 2. Not only can the polyester yarn be dyed more evenly and effectively by the heated dyeing agent, but the gas emitted by the heated dyeing agent will also be more easily gathered inside the cover plate 41 due to the high temperature, and will be restricted by the cover plate 41 and adsorbed by the connecting pipe 42.

[0030] Specifically, an exhaust block 51 is fixedly connected to one side of the treatment box 43. One side of the exhaust block 51 is connected to the inside of the treatment box 43. An activated carbon plate 52 is provided inside the exhaust block 51. The activated carbon plate 52 can filter and adsorb some of the remaining gas, thereby further reducing the harmful substances contained in the gas and further improving the safety of dyeing polyester filament.

[0031] Specifically, the cleaning mechanism 11 includes a water pipe 111 fixedly connected to the inside of the cleaning tank 1, a water pump 112 installed on the outside of the water pipe 111, a nozzle 113 fixedly connected to one end of the water pipe 111, and a filter screen 114 installed inside the cleaning tank 1. The water pump 112 can draw water from the inside of the cleaning tank 1 through the water pipe 111 and spray it out through the nozzle 113 to clean the polyester yarn before dyeing. At the same time, the filter screen 114 can filter dust and particles in the water drawn by the water pump 112, so that the water sprayed out by the nozzle 113 is relatively clean.

[0032] Specifically, the drying mechanism 10 includes a fixing block 101 fixedly connected to the upper side of the dyeing tank 2. A third heating plate 102 and a fixing plate 103 are fixedly connected to the inner side of the fixing block 101. A second fan 104 is fixedly connected to the inner side of the fixing plate 103. The fixing block 101 can connect the third heating plate 102 and the fixing plate 103. The third heating plate 102 can heat the air around the second fan 104 during operation. The second fan 104 can draw hot air during operation and blow it smoothly onto the dyed polyester filament, thereby achieving the drying of the polyester filament.

[0033] Specifically, a baffle 6 is fixedly connected to the inside of the processing box 43, and a collection box 7 is provided inside the processing box 43. The collection box 7 can collect the condensed water droplets, while the baffle 6 can block the gas entering the processing box 43 to a certain extent, so that it is not easy for the gas to flow directly out of the gas outlet block 51 after entering the processing box 43, and condensation can be carried out more smoothly.

[0034] Specifically, a first fan 8 is fixedly connected to the inner side of the connecting block 45, and the first fan 8 is located on the outer side of the connecting block 45. An inclined plate 9 is fixedly connected to the inner side of the cover plate 41. The first fan 8 can dissipate heat from the semiconductor cooling chip 46 during operation, so that the semiconductor cooling chip 46 can perform better. At the same time, the inclined plate 9 can facilitate the flow of gas accumulated on the inner side of the cover plate 41 to one side of the connecting pipe 42 through its inclined surface.

[0035] The working principle and usage process of this utility model are as follows: When the device is in use, the feeding roller 31 starts to rotate, releasing the polyester filaments to be dyed. The polyester filaments are held by the first holding roller 32 to ensure stable transmission and movement in the washing tank 1. At this time, the workers can start the water pump 112. The water pump 112 draws water from the washing tank 1 through the water pipe 111. After being filtered by the filter screen 114, the water is sprayed out by the nozzle 113 to clean the polyester filaments. The cleaned polyester filaments are transferred to the dyeing tank 2 through the first transmission roller 33. The second heating plate 482 heats the dyeing agent in the dyeing tank 2 to improve the dyeing effect. The dyed polyester filaments are transferred to the drying mechanism 10 through the second transmission roller 35. The third heating plate 102 heats the air, and the second fan 104 blows the hot air onto the polyester filaments to achieve drying. The dried polyester filaments are then wound up by the winding roller 36.

[0036] While dyeing polyester filaments, the harmful gases emitted by the heated dyeing agent are confined above the dyeing tank 2 by the cover plate 41. The vacuum pump 441 draws out the gas confined by the cover plate 41 through the connecting pipe 42. The gas is heated by the first heating plate 472 in the connecting pipe 42. The heated gas enters the processing box 43. The semiconductor cooling chip 46 cools the gas, causing it to condense and remove water vapor and some volatile substances. The condensed water droplets fall into the collection box 7, while the gas continues to flow in the processing box 43. After being filtered by the activated carbon plate 52, it is discharged through the gas outlet block 51.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
