Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: A polyester fabric dyeing apparatus, such as Figures 1-5 As shown, the apparatus includes a base 1, on which a dyeing box 2 is fixedly mounted. The dyeing box 2 has a front-to-back open feed inlet on its top front side and a front-to-back open discharge outlet on its rear front side. The dyeing box 2 is filled with dye liquor 3. Two first rolls of cloth 4, extending horizontally and spaced apart, are rotatably mounted inside the dyeing box 2 via a rotating shaft. Two sets of second rolls of cloth 5, extending horizontally and spaced apart, are also rotatably mounted inside the dyeing box 2 via a rotating shaft. Each set includes two second rolls of cloth 5 spaced apart horizontally. The two sets of second rolls of cloth 5 are located below the two first rolls of cloth 4, and the second rolls of cloth 5 are positioned below the dye liquor 3. Inside, two polyester fabrics 6 are driven together on the first roll of fabric 4 and the two second rolls of fabric 5, which are spaced apart from each other. The polyester fabrics 6 pass through the inlet and outlet in sequence. The polyester fabrics 6 are wrapped in a U-shape above the first roll of fabric 4 and below the second rolls of fabric 5. A drive motor 7 is fixedly installed on the right side of the dyeing box 2. The right end of the rotating shaft on the first roll of fabric 4 at the front passes through the dyeing box 2 and is fixedly connected to the output shaft of the drive motor 7. The drive motor 7 can drive the polyester fabrics 6 to be driven on the first roll of fabric 4 and the second rolls of fabric 5 through the first roll of fabric 4. At the same time, the polyester fabrics 6 are inserted into the dye liquor 3 for dyeing.

[0023] The left end of the rotating shaft on the first roll of fabric 4 passes through the dyeing box 2 and is fixedly equipped with a tensioning wheel 9. The two tensioning wheels 9 are equipped with a belt 10 for transmission. The two tensioning wheels 9 and the belt 10 can transmit the rotational power of the first roll of fabric 4 located in front to the first roll of fabric 4 located behind, thereby increasing the uniformity of force during the conveying process of polyester fabric 6 and avoiding slippage or excessive tension, which would cause the polyester fabric 6 to wrinkle or stretch.

[0024] The adjusting mechanism 8 is arranged on the dye box 2, the two groups of second cloth rollers 5 are arranged on the adjusting mechanism 8, the adjusting mechanism 8 is used to adjust the height of the two groups of second cloth rollers 5, so as to change the length of the polyester fabric 6 entering the dyeing liquid 3, so that the residence time of the polyester fabric 6 in the dyeing liquid is changed without changing the rotating speed of the first cloth roller 4 and the second cloth roller 5, the tension and the running stability of the polyester fabric 6 are avoided to be affected, and then the dyeing quality is avoided to be affected, specifically, the adjusting mechanism 8 comprises an inner threaded sleeve 81 which is rotatably arranged on the top of the dye box 2, a rotating handle 82 is fixedly arranged on the outer circumferential surface of the inner threaded sleeve 81, a lifting rod 83 is rotatably arranged in the inner threaded sleeve 81, an outer thread is arranged on the top outer circumferential surface of the lifting rod 83, the lifting rod 83 is threadedly connected with the inner threaded sleeve 81 through the outer thread, a bearing support 84 is fixedly arranged at the bottom end of the lifting rod 83, the bearing support 84 comprises a fixed plate 841 and two ball bearings 842 which are fixedly arranged on the fixed plate 841, the middle portions of the rotating shafts of the two second cloth rollers 5 are rotatably arranged on the bearing support 84, and the bearing support 84 is located between the two second cloth rollers 5 in the same group.

[0025] The rotating handle 82 is rotated to drive the inner threaded sleeve 81 to rotate, then the lifting rod 83 is driven to move up and down through the thread action of the outer thread on the lifting rod 83, then the bearing support 84 at the bottom end of the lifting rod 83 and the two groups of second cloth rollers 5 are driven to move up and down, so that the height of the two groups of second cloth rollers 5 is adjusted.

[0026] The left and right inner walls of the dye box 2 are fixedly provided with U-shaped guide frames 11, the left and right ends of the two groups of second cloth rollers 5 are provided with bearing supports 84, the bearing supports 84 are slidably arranged in the U-shaped guide frames 11, and the left and right ends of the rotating shafts located on the second cloth rollers 5 are rotatably arranged on the bearing supports 84 located in the U-shaped guide frames 11; the U-shaped guide frames 11 can guide the second cloth rollers 5 through the bearing supports 84, can keep horizontal and move up and down when being pulled by the lifting rod 83, and can prevent the lifting rod 83 from rotating with the inner threaded sleeve 81 when the lifting rod 83 is driven to move up and down by the rotation of the inner threaded sleeve 81.

[0027] The bearing supports 84 located at the two ends of the second cloth rollers 5 are fixedly provided with connecting rods 12 which are obliquely extended to the middle portion of the lifting rod 83, the connecting rods 12 can directly connect the three bearing supports 84 with the lifting rod 83, and can prevent the second cloth rollers 5 from being unevenly stressed during the lifting process.

[0028] The pressing roller 13 is rotatably arranged in the dye box 2 through the rotating shaft, the pressing roller 13 is arranged above the first cloth roller 4 located at the rear, the polyester fabric 6 is arranged between the pressing roller 13 and the first cloth roller 4, the pressing roller 13 can extrude the polyester fabric 6, extrude the dyeing liquid attached to the surface of the polyester fabric 6, and flow back into the dye box 2, so as to prevent the dyeing liquid 3 on the surface of the polyester fabric 6 from splashing everywhere during rapid conveying.

[0029] The right end of the rotating shaft on the pressing roller 13 penetrates the dye box 2 and is fixed with a first spur gear 14, the right end of the rotating shaft on the rear first roller 4 penetrates the dye box 2 and is fixed with a second spur gear 15, the first spur gear 14 meshes with the second spur gear 15, so that the pressing roller 13 can be driven to rotate to press the polyester fabric 6, compared with the mode that the polyester fabric 6 drives the pressing roller 13 to rotate in the conveying process, the polyester fabric 6 can be prevented from being wrinkled and stretched due to resistance.

[0030] Working principle: when the polyester fabric 6 is dyed, the driving motor 7 drives the two first rollers 4 to rotate in the same direction through the tension pulley 9 and the belt 10 to convey the polyester fabric 6, the polyester fabric 6 passes around the front first roller 4 and then passes through the two second rollers 5 in a U shape, and then enters the dye liquor 3 to be dyed, and then the dyed polyester fabric 6 is outputted by passing around the rear first roller 4.

[0031] When it is needed to change the residence time of the polyester fabric 6 in the dye liquor, the rotating handle 82 is rotated to drive the inner threaded sleeve 81 to rotate, and then the lifting rod 83 is driven to move up and down through the threaded action of the outer thread on the lifting rod 83, and then the bearing bracket 84 at the bottom end of the lifting rod 83 and the two groups of second rollers 5 are driven to move up and down, the height of the second roller 5 is changed, the length of the polyester fabric 6 passing around the second roller 5 and entering the dye liquor 3 is changed, and the residence time of the polyester fabric 6 in the dye liquor is changed without changing the rotating speed of the first roller 4 and the second roller 5.

[0032] It is apparent for those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and the present application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalents of the elements of the claims are intended to be embraced therein.
