Description

Technical Field

[0001] The utility model relates to the technical field of polyester thread production, in particular to a polyester thread dyeing device with a dye recovery structure. Background Art

[0002] Polyester thread is a synthetic fiber commonly used in textile manufacturing, such as clothing, bedding, industrial ropes, sewing thread, etc. It is a filament made of polyester polymers; polyester is a plastic material with good heat resistance and chemical resistance, which is used to make polyester thread, which makes polyester thread have many excellent properties.

[0003] First of all, polyester thread has high strength and wear resistance, which makes the textiles made from it have good durability. At the same time, the fiber structure of polyester thread makes it not easy to wrinkle, and can maintain the smooth appearance of the textiles for a long time. Moreover, polyester thread is not sensitive to heat, so it can maintain its performance even at high temperatures. Textiles made of polyester thread are easy to clean and maintain, and are not easy to fade.

[0004] During the dyeing process, polyester thread needs to be dyed in a dye pool first, and then cleaned and dried to complete the dyeing. However, during the dyeing and transportation process, in addition to the dye entering the inside of the polyester thread, excess dye and water will also adhere to the surface of the polyester thread and enter the cleaning pool or drying process with the polyester thread, resulting in a waste of dye.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 2As shown, it comprises a device housing 1, a line inlet 2 is provided at the front side of the device housing 1, a line outlet 3 is provided at the rear end of the device housing 1, a plurality of guide shafts 8 for guiding polyester lines are provided in the device housing 1, a dye pool 4 is provided at the front side of the bottom of the device housing 1, a cleaning pool 5 is provided at the rear side of the dye pool 4, a vibration structure is provided above the dye pool 4 and the cleaning pool 5, and a circulating dye recovery structure is connected to the rear of the cleaning pool 5;

[0022] The plurality of guide shafts 8 are all rotatably mounted, and a portion of the guide shafts 8 are staggeredly disposed in the dye pool 4 and the cleaning pool 5 .

[0023] See also Figure 1-Figure 4 As shown, the vibration structure includes a vibration shaft 9 installed in the device housing 1, and both ends of the vibration shaft 9 are connected to the inner wall of the device housing 1 through springs 11, and one end of the vibration shaft 9 is installed with a vibration motor 10 through a mounting seat.

[0024] As an optimization scheme of the utility model, the vibration shaft 9 is driven to generate vibration, and the vibration is transmitted to the polyester line, so that the droplets attached to the polyester line are shaken off by the vibration, thereby reducing the transfer of water between the dye pool 4, the cleaning pool 5 and the subsequent drying equipment.

[0025] See also Figure 1-Figure 4 As shown, the circulating dye recovery structure includes a filter box 6 arranged on one side of the cleaning tank 5, a water pump 7 is provided on one side of the filter box 6, the water pump end of the water pump 7 is connected to the cleaning tank 5, the water outlet end of the water pump 7 is connected to one end of the filter box 6, and the other end of the filter box 6 is connected to the cleaning tank 5 through a return pipe 12; a plurality of filter membranes are provided in the filter box 6.

[0026] As an optimization scheme of the present invention, a water pump 7 is used to continuously pump out water from the cleaning tank 5 and send it into the filter box 6. The dye mixed into the water during the cleaning process is filtered out using a filter membrane and the water is discharged back into the cleaning tank 5. While reducing the subsequent recovery pressure, the cleaning ability of the water in the cleaning tank 5 is greatly enhanced, thereby reducing the frequency of water changes and improving the cleaning quality.

[0027] The use process of this utility model:

[0028] First, install the equipment, and then insert the polyester thread to be dyed from the thread inlet 2, and then pass through several guide shafts 8 in sequence into the dye pool 4, pass through the staggered guide shafts 8 in the dye pool 4, and then pass through the vibration shaft 9 above the dye pool 4, and then pass into the cleaning pool 5, and also pass through the guide shaft 8, pass through the vibration shaft 9 above the filter box 6, and then pass through the thread outlet 3, and then connect to the subsequent drying equipment;

[0029] During the dyeing process, after the polyester thread has been dyed in the dye pool 4, the droplets attached to the polyester thread will be dropped off by the vibration when passing through the vibration shaft 9 above, and fall back into the dye pool 4, thereby reducing the loss of dye in the dye pool 4. Then the polyester thread enters the cleaning pool 5 for cleaning. After the cleaning is completed, the droplets will also be dropped off by the vibration shaft 9 above the cleaning pool 5, and fall back into the cleaning pool 5. The circulating dye recovery structure will continue to filter the water in the cleaning pool 5 to filter out the dye.

[0030] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
