Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1 , 6 As shown in Figure 7, a fabric dyeing machine of the present invention includes a dyeing box 1 and a mixing tank 11. A drive motor 12 is fixedly mounted on the upper end of the dyeing box 1. A fabric lifting roller 121 is rotatably mounted inside the dyeing box 1. The output end of the drive motor 12 is connected to the fabric lifting roller 121. An overflow pipe 122 is mounted on the left side inside the dyeing box 1. A mixing mechanism is mounted on the mixing tank 11. A return pipe 123 and a conveying pipe 124 are connected between the mixing tank 11 and the dyeing box 1. A water pump 125 is mounted on both the return pipe 123 and the conveying pipe 124. A heat exchange component is mounted on the conveying pipe 124. An electric valve is mounted on the return pipe 123.

[0031] The fabric lifting roller 121 is equipped with partition plates 1211 at both the front and rear ends. Several evenly distributed silicone strips 1212 are mounted on the outer side of the fabric lifting roller 121. Several evenly distributed I-shaped grooves 1213 are opened on the outer side of the fabric lifting roller 121. The shape of the silicone strips 1212 on the side near the fabric lifting roller 121 is designed to match the I-shaped grooves 1213. The matching of the bottom I-shaped silicone strips 1212 with the I-shaped grooves 1213 facilitates the installation and removal of the silicone strips 1212. Furthermore, due to the deformable nature of silicone, it can be set to an interference fit with the I-shaped grooves 1213, thereby ensuring the stability of the silicone strips 1212 and making the installation and removal of the silicone strips 1212 more convenient. Several anti-slip protrusions 1214 are fixed on the side of the silicone strips 1212 away from the fabric lifting roller 121. The anti-slip protrusions 1214 facilitate the fabric conveying by the fabric lifting roller 121.

[0032] like Figure 6 , 8 As shown, a support pipe 13 is fixedly installed inside the dyeing box 1, and the support pipe 13 is connected to the conveying pipe 124. A ring pipe 131 is fixedly installed on the side of the overflow pipe 122, and the ring pipe 131 is connected to the support pipe 13. The left and right sides of the ring pipe 131 are connected to the inside of the overflow pipe 122. An inclined block 132 is fixedly installed on both the left and right sides inside the overflow pipe 122. The inclined block 132 is located above the connection between the overflow pipe 122 and the ring pipe 131. A U-shaped block 133 is fixedly installed at the lower end of the inclined block 132. Both the inclined block 132 and the U-shaped block 133 are hollow designs. A triangular fabric opening 134 is opened in the middle of the lower end of the overflow pipe 122. Spherical arc surfaces 135 are provided on both the left and right sides of the bottom of the overflow pipe 122. The spherical arc surfaces 135 and the U-shaped blocks 133 can guide the flowing dye, so that the dye enters the dyeing box. The overflow pipe 122 impacts the fabric to improve the dyeing effect. Two opposing silicone sheets 136 are fixedly mounted on the lower middle part of the overflow pipe 122. The two silicone sheets 136 are close together to form an inverted V shape. The two silicone sheets 136 are located above the triangular fabric opening 134. The design of the triangular fabric opening 134 and the two inverted V-shaped silicone sheets 136 facilitates the entry of the fabric into the overflow pipe 122. During use, the two silicone sheets 136 are subjected to water pressure, making them closer to the fabric and preventing the dye from flowing out from below the overflow pipe 122. This avoids the dye flowing into the dyeing box 1 before it has fully contacted the fabric. In the process of using the same amount of dye, the dyeing efficiency and dyeing effect of the fabric can be improved.

[0033] like Figure 4-5 As shown, the mixing mechanism includes a mixing motor 14, which is fixedly mounted on the lower end of the mixing tank 11. A mixing disc 141 is rotatably mounted inside the mixing tank 11. The mixing disc 141 is connected to the output end of the mixing motor 14. Several evenly distributed mixing plates 142 are inclined on the side of the mixing disc 141. The dye can be stirred and mixed evenly by the several rotating mixing plates 142.

[0034] The mixing mechanism also includes a fixed plate 143 and a fixed column 144. The fixed plate 143 is fixedly mounted on the upper end of the mixing tank 11, and the fixed column 144 is fixedly mounted on the lower end of the fixed plate 143. A transmission box 145 is rotatably and sealed on the lower side of the fixed column 144. A connecting rod 146 is fixedly mounted between the transmission box 145 and the mixing disc 141. Several rotating rods 147 are rotatably and sealed on the transmission box 145. A bevel gear 148 is fixedly mounted on one end of the several rotating rods 147 near the transmission box 145 and the lower end of the fixed column 144. The bevel gears 148 of the several rotating rods 147 mesh with the bevel gears 148 of the fixed column 144. A mixing blade 149 is fixedly mounted on the other end of the several rotating rods 147. During the rotation of the mixing disc 141, the transmission box 145 can be driven to rotate, thereby causing the rotating rods 147 and the mixing blade 149 to rotate. In this way, the efficiency of dye mixing can be improved by stirring in the horizontal and vertical directions.

[0035] like Figure 2 As shown, the heat exchange assembly includes a heat exchange tube 15, which is connected to the middle of the delivery pipe 124. The left and right sides of the heat exchange tube 15 are respectively connected to an inlet 151 and an outlet 152. The inlet 151 and the outlet 152 can be connected to an external heating device. The heat exchange liquid is delivered to the heat exchange tube 15 through the inlet 151, thereby heating the dye in the thin tube 153. Several evenly distributed thin tubes 153 are assembled in the middle of the heat exchange tube 15, and the several thin tubes 153 are all connected to the delivery pipe 124.

[0036] like Figure 2 , 3 As shown in Figure 6, an adjustment mechanism is installed on the right side inside the dyeing box 1. The adjustment mechanism includes an adjustment cylinder 16, which is rotatably installed inside the dyeing box 1. A servo motor 161 is fixedly installed on the outside of the dyeing box 1, and a disc 162 is rotatably installed on the outside of the dyeing box 1. The disc 162 is connected to the output end of the servo motor 161. An adjustment rod 163 is fixedly installed on the rotating shaft of the adjustment cylinder 16. A strip-shaped groove 1631 is opened in the middle of the adjustment rod 163. A round block 1632 is fixedly installed on one side of the front end of the disc 162. The round block 1632 rotates and slides in match with the strip-shaped groove 1631. The servo motor 161 drives the disc 162 to rotate, so that the round block 1632 slides and rotates inside the strip-shaped groove 1631, causing the adjustment cylinder 16 to swing back and forth. This can evenly distribute the fabric and make the fabric stacked in an orderly manner in the dye inside the dyeing box.

[0037] The adjustment mechanism also includes an air supply assembly, which includes a bellows 164. The bellows 164 is fixedly mounted on the side of the dyeing box 1. Fan blades are rotatably mounted inside the bellows 164. The fan blades are connected to the output end of the servo motor 161. An air supply pipe 1641 is connected between the front end of the bellows 164 and the dyeing box 1. A baffle 165 is fixedly mounted on the right side inside the dyeing box 1. An air supply duct 1651 is fixedly mounted on the lower side of the baffle 165. The air supply duct 1651 is connected to the rear end of the bellows 164. The air supply duct 1651 and the baffle 165 are together provided with an air duct 1652. Air is supplied by the fan blades, so that the middle section of the upper side of the fabric is transported smoothly.

[0038] When dyeing fabric using this device, the dye is first mixed in the mixing tank 11. The mixing motor 14 is then started, driving the mixing disc 141 and transmission box 145 to rotate. The dye is mixed evenly by the mixing blades 142 evenly distributed on the mixing disc 141 and the mixing blades 149 on the rotating rod 147. The mixed dye is then transported to the heat exchange tube 15 through the conveying pipe 124. An external heating device supplies heating liquid to the heat exchange tube 15. Heat exchange occurs as the dye passes through the thin tube 153. The heated dye then passes through the support tube 13 and the ring tube 131 into the lower part of the overflow pipe 122. The fabric roller 121, driven by the drive motor 12, begins to convey the fabric. The conveyed fabric enters the overflow pipe 122 through the triangular fabric inlet 134. At the same time, the dye is guided by the inclined block 132, the U-shaped block 133, and the spherical arc surface 135 to both sides of the fabric, thereby impacting and soaking the fabric. This makes it easier for the dye to penetrate the fabric for dyeing, allowing the freshly heated and mixed dye to fully act on the fabric surface, thus improving the dyeing efficiency. After the fabric dyeing is completed, the dye inside the dyeing box 1 can be recovered through the return pipe 123, thereby reducing dye waste.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
