Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This embodiment discloses a scouring apparatus and a fabric dyeing process. The dyeing process includes a pretreatment process, a dyeing process, a washing process, a color-fixing process, and a post-treatment process. The pretreatment process includes a singeing process, a desizing process, a scouring process, and a bleaching process.

[0023] like Figure 1 As shown, the scouring process includes a scouring device, which includes a pool body 1 and a cover plate 2. The top of the pool body 1 is open, and a cavity 11 is provided inside the pool body 1. The fabric 4 is scouring in the cavity 11 to remove impurities from the fibers.

[0024] like Figure 1 , Figure 4 As shown, the cover plate 2 is a flat plate structure and can be hung on the upper end of the pool body 1. Two opposing side plates 21 are installed at the bottom of the cover plate 2, and a hook 7 is installed at the top of the cover plate 2. The hook 7 is used to connect a lifting device to move the cover plate 2 up and down. When the cover plate 2 is hung on the upper end of the pool body 1, the side plates 21 are inserted into the cavity 11.

[0025] like Figure 1 , Figure 2 As shown, multiple moving units 3 are installed between the two side plates 21 (only two moving units 3 are shown in the figure for illustration). The moving unit 3 includes component 1 31 and component 2 32. Both component 1 31 and component 2 32 can move up and down. Component 1 31 is set in pairs and is located on both sides of component 2 32.

[0026] Specifically, component 31 includes guide rod 311 and cylinder 312, combined with Figure 2 , Figure 3 The guide rod 311 is a rectangular long rod structure. The side plate 21 is provided with a groove 211. The two ends of the guide rod 311 are respectively inserted into the groove 211. The two ends of the guide rod 311 can move up and down along the inner wall of the groove 211. Figure 1 , Figure 2 (As shown in the orientation). The cylinder body 312 is a cylindrical structure. A guide rod 311 passes through the cylinder body 312, with both ends of the guide rod 311 extending out of the cylinder body 312 and inserting into the groove 211. A plug rod 314 is installed on the cylinder body 312. The plug rod 314 is threadedly inserted into the inner wall of the cylinder body 312, and its axial direction is radially aligned with the cylinder body 312, extending radially inwards. A spring 315 is fitted onto the plug rod 314. One end of the spring 315 abuts against the inner wall of the cylinder body 312, and the other end abuts against the guide rod 311. The cylinder 312 is provided with a groove 3121, which extends radially outward along the inner wall of the cylinder 312. The length of the groove 3121 is axially arranged along the guide rod 311. The guide rod 311 is inserted into the groove 3121 on the side away from the spring 315. The guide rod 311 can move left and right along the inner wall of the groove 3121. Figure 1 , Figure 2 (As shown in the diagram). The width of guide rod 311 is the same as the width of groove 3121. Under the action of spring 315, the side of guide rod 311 away from spring 315 abuts against the inner wall of groove 3121, so that when guide rod 311 moves up and down ( Figure 1 , Figure 2 (As shown in the orientation), guide rod 311 can drive cylinder 312 to move synchronously.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, guide rod 311 has movable rods 331 installed on both sides. Screws 33 are installed on the movable rods 331, passing through the cover plate 2 and the movable rods 331. The screws 33 and movable rods 331 are connected by a helical drive. The screws 33 are driven to rotate by a motor 332, which in turn drives the movable rods 331 to move up and down, thus moving the guide rod 311 up and down. A guide rail 6 is installed on the side plate 21, and the movable rods 331 are slidably connected to the guide rail 6.

[0028] like Figure 3As shown, the movable rod 331 is slidably connected to the cylinder 312. The movable rod 331 includes an extension rod 3311, which passes through the cylinder 312 and is threadedly connected to the guide rod 311. This prevents the cylinder 312 from rotating, thus preventing the guide rod 311 from becoming misaligned with the trough 3121 when they are disengaged, which would prevent the guide rod 311 from being inserted into the trough 3121.

[0029] like Figure 2 , Figure 3 As shown, component 1 31 also includes outer cylinder 313, which is fitted into cylinder 312. Outer cylinder 313 can rotate along its own axis. Component 2 32 includes outer cylinder 323, which can rotate along its own axis. Outer cylinder 1 313 and outer cylinder 2 323 are used to guide fabric 4. In the working state, component 1 31 is positioned higher than component 2 32. Outer cylinder 1 313 and outer cylinder 2 323 are triangularly distributed. Fabric 4 passes from the top of outer cylinder 1 313, around the bottom of outer cylinder 2 323, and around the top of another outer cylinder 1 313. Fabric 4 can be transported and moved back and forth in the scouring liquid in cavity 11, so that the scouring liquid (usually caustic soda solution) can impact the surface of fabric 4, accelerate the removal of impurities from the fibers of fabric 4, and improve production efficiency.

[0030] like Figures 1-3 As shown, a cylinder 351 is fixedly installed at the bottom of the cover plate 2, and a push block 35 is fixedly installed at the output end of the cylinder 351. In the working state, the push block 35 is located on the side of cylinder 312 away from the other cylinder 312. The push block 35 can move towards the side of cylinder 312 to push cylinder 312, thereby bringing the two cylinders 312 closer together. When the push block 35 moves away from the side of cylinder 312 to release cylinder 312, the two cylinders 312 move away from each other under the action of spring 315. Through the action of the push block 35, the two cylinders 312 continuously move closer and further away from each other, driving the fabric 4 to move, so that the scouring liquor impacts the fabric 4, thereby facilitating the removal of impurities from the fibers of the fabric 4 and improving process efficiency. At the same time, the movement of the fabric 4 can enhance the flow of the scouring liquor, so that the concentration of the effective component (NaOH) in the scouring liquor near the fabric 4 can be increased, thereby improving the reaction efficiency.

[0031] like Figure 2As shown, component 2 32 has a similar structure to component 1 31. Component 2 32 also includes guide rod 2 321 and cylinder 2 322. Cylinder 2 322 is a cylindrical structure. Guide rod 2 321 passes through cylinder 2 322, with both ends of guide rod 2 321 extending out of cylinder 2 322 axially. Outer cylinder 2 323 is fitted onto the outer wall of cylinder 2 322. Side plate 21 also has a groove 2 212, which is parallel to groove 1 211. Guide rod 2 321 is inserted into groove 2 212 axially, and can move up and down along the inner wall of groove 2 212. Movable rods 2 341 are installed at both ends of guide rod 2 321. Screw rods 2 341 are helically connected to movable rods 2 341, and screw rods 2 34 pass through movable rods 2 341. Screw rods 2 342 are driven by motor 2 342 to rotate, thereby achieving up and down movement. Multiple insertion rods 324 are fixedly installed on the inner wall of the second cylinder 322. Multiple insertion rods 324 are distributed along the axial direction of the second cylinder 322. Each insertion rod 324 is fitted with a spring 325. One end of the spring 325 abuts against the inner wall of the second cylinder 322, and the other end abuts against a guide rod 321. The guide rod 321 is slidably inserted into the second cylinder 322 on the side away from the spring 325, with the insertion direction being vertical, thus allowing the second cylinder 322 to move synchronously with the guide rod 321. When the two first cylinders 312 within the same moving unit 3 are moving away from each other, the spring 325 is in a compressed state. Therefore, by setting the spring 325, when the two first cylinders 312 within the same moving unit 3 approach each other and pull the fabric 4 inward, the tension of the fabric 4 weakens, and the spring 325 can promptly push the outer cylinder 323 downward, preventing the fabric 4 from loosening and helping the scouring liquid to exert a better impact on the fabric 4.

[0032] like Figure 1 As shown, the side plate 21 is equipped with rollers 5, which are located at the input end and the output end of the fabric 4 and are used to guide the fabric 4.

[0033] When installing the fabric 4, lift the cover plate 2 upwards, move the outer cylinder 1 313 to a lower position, while the outer cylinder 2 323 remains stationary in its lower position. Wrap the fabric 4 around the bottom of the two rollers 5, then move the outer cylinder 1 313 upwards. During this upward movement, the outer cylinder 1 313 bends the fabric 4 to form a zigzag path, increasing the contact area between the fabric 4 and the boiling solution and preventing fabric 4 from accumulating and affecting reaction efficiency. For the operator, the installation position of the fabric 4 can be raised to a high position, which is very convenient.

[0034] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
