DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific implementation methods.

[0021] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are with reference to the position state of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be understood as special limitations on the technical solution provided by the utility model.

[0022] like Figure 1-Figure 4 As shown, a polyester fabric dyeing device includes a dyeing kettle body 1, which is arranged horizontally. A jacket 3 is provided at the bottom of the dyeing kettle body 1. The jacket 3 is hollow. A liquid inlet pipe 31 and a liquid outlet pipe 32 are provided on one side of the jacket 3. The jacket 3 is U-shaped, and the inner wall of the jacket 3 is in close contact with the outer wall of the dyeing kettle body 1. A heating liquid such as heat transfer oil or hot water is injected into the hollow space of the jacket 3 through the liquid inlet pipe 31 and the liquid outlet pipe 32, so that the dye liquid in the dyeing kettle body 1 can be heated to a suitable temperature.

[0023] At least two convex rings 6 are provided on the dyeing kettle body 1, one of which is provided with teeth. A first rotating motor 41 is provided on one side of the dyeing kettle body 1, a first rotating rod 42 is provided on one side of the first rotating motor 41, a gear 43 is provided on the first rotating rod 42, and the gear 43 is arranged with the teeth on the convex ring 6 for transmission; a fixed ring sleeve 7 is provided between the two convex rings 6, an opening 8 is provided on the top of the fixed ring sleeve 7, and a feeding assembly 2 is provided at the opening 8, a through hole 9 is provided on the side wall of the dyeing kettle body 1, and the through hole 9 is arranged between the two convex rings 6 and is arranged in coordination with the opening 8, that is, when the gear 43 rotates, the dyeing kettle body 1 is rotated through the transmission of the teeth, and the opening 8 is sealed by the fixed ring sleeve 7 during rotation to prevent the dye liquid from leaking out (such as Figure 1 As shown); when dye liquor needs to be input or discharged, or fabric needs to be put in or taken out, the opening 9 on the side wall of the dyeing kettle body 1 is aligned with the opening 8.

[0024] As shown in the figure, four convex rings 6 are provided, wherein a fixed ring sleeve 7 is provided between two adjacent convex rings 6, that is, two fixed ring sleeves 7 are provided, and the tops of the two fixed ring sleeves 7 are provided with openings 8, and a feeding assembly 2 is provided at the opening 8. Providing two groups of feeding assemblies 2 is more conducive to quickly inputting or discharging dye liquid and putting in and taking out fabrics.

[0025] The feed assembly 2 includes a feed pipe 21 and an opening and closing cover 22, and the feed pipe 21 and the opening and closing cover 22 are arranged in cooperation. A second rotating motor 51 is arranged on one side of the dyeing kettle body 1, and a second rotating rod 52 is arranged on one side of the second rotating motor 51. The second rotating rod 52 extends into the dyeing kettle body 1, and a plurality of stirring paddles are arranged on the second rotating rod 52. The stirring paddles include a first stirring paddle 53 and a second stirring paddle 54 arranged on both sides of the first stirring paddle 53. The length of the second stirring paddle 54 is less than the length of the first stirring paddle 53. The stirring paddles arranged in this way can make the dyeing liquid be heated more evenly when stirring the dyeing liquid and the fabric being dyed, and the coloring and fixing effects of the fabric are better.

[0026] A first support frame 44 is provided at the bottom of the first rotary motor 41, and a second support frame 55 is provided at the bottom of the second rotary motor 51 for supporting the motor structure. A first valve 33 is provided on the liquid inlet pipe 31, and a second valve 34 is provided on the liquid outlet pipe 32. The first valve 33 and the second valve 34 are used to control the capacity of the heated liquid in the hollow space of the jacket 3, so that the temperature of the heated liquid in the hollow space is kept in a state suitable for dyeing.

[0027] Here’s how it works:

[0028] First, the staff drives the first rotary motor 41, aligns the through hole 9 on the side wall of the dyeing kettle body 1 with the opening 8 on the top of the fixed ring sleeve 7, and then turns off the first rotary motor 41. Then, the opening and closing cover 22 on the top of the dyeing kettle body 1 is opened, and the dye solution is introduced into the dyeing kettle body 1 through the feed pipe 21, and the opening and closing cover 22 is closed. After that, the first valve 33 on the liquid inlet pipe 31 is opened, and the heat transfer oil is poured into the jacket 3 until the heat transfer oil fills the hollow space of the jacket 3, and the first rotary motor 41 is driven to drive the dyeing kettle body 1 to rotate, so that the dye solution is heated evenly. Alternatively, the second rotary motor 51 can be driven at the same time to drive the stirring paddle to stir the dye solution.

[0029] After the dye liquor is heated for a period of time, the through hole 9 is aligned with the opening 8, the opening and closing cover 22 is opened, and the polyester fabric is put into the dyeing kettle body 1 through the feeding pipe 21, and then the opening and closing cover 22 is closed. It should be noted that in order to keep the temperature of the dye liquor in the dyeing kettle body 1 at a suitable state, the first valve 33 on the liquid inlet pipe 31 and the second valve 34 on the liquid outlet pipe 32 can be opened at the same time, so that the heat transfer oil in the jacket 3 is in a flowing state, and the dye liquor in the dyeing kettle body 1 is continuously heated.

[0030] After dyeing for a period of time, turn off the first rotating motor 41 (or / and the second rotating motor 51), align the through hole 9 with the opening 8, open the opening and closing cover 22, take out the polyester fabric in the dyeing kettle body 1, close the first valve 33 on the liquid inlet pipe 31, drain the heat transfer oil in the jacket 3, and then close the second valve 34 on the liquid outlet pipe 32.

[0031] The present application arranges a hollow jacket 3 at the bottom of a dyeing kettle body 1 which is arranged horizontally, and injects a heating liquid such as heat-conducting oil or hot water into the jacket 3, and cooperates with the rotatable dyeing kettle body 1 and the stirring paddle arranged in the dyeing kettle body 1, so that the dye liquid in the dyeing kettle body 1 is heated evenly, the dyeing temperature is appropriate, the coloring and fixing time of the polyester fabric is shortened, the energy consumption is reduced, and the dyeing efficiency is improved; and the dye liquid can be fully adsorbed on the fabric, reducing the burden of wastewater treatment.

[0032] The above-mentioned implementation mode is only used to explain the inventive concept of the utility model, and is not intended to limit the protection of the rights of the utility model. Any non-substantial changes to the utility model using this concept shall fall within the protection scope of the utility model.
