DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] This embodiment discloses a scouring device and a fabric dyeing process. The dyeing process includes a pretreatment process, a dyeing process, a cleaning process, a color fixation 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 pool body 1 is open at the top, and a cavity 11 is provided in the pool body 1. The fabric 4 is scourred in the cavity 11 to remove impurities in the fiber.

[0024] like Figure 1 , Figure 4 As shown, the cover plate 2 is a flat plate structure, and the cover plate 2 can be hung on the upper end of the tank body 1. Two side plates 21 arranged opposite to each other 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 the lifting device to move the cover plate 2 up and down. When the cover plate 2 is hung on the upper end of the tank body 1, the side plates 21 are inserted into the cavity 11.

[0025] like Figure 1 , Figure 2 As shown, a plurality of mobile units 3 are installed between the two side plates 21 (only two mobile units 3 are drawn in the figure for schematic representation), and the mobile units 3 include component one 31 and component two 32. Both component one 31 and component two 32 can move up and down, and component one 31 is arranged in pairs, and component one 31 is located on both sides of component two 32.

[0026] Specifically, the component 31 includes a guide rod 311 and a cylinder 312. Figure 2 , Figure 3 The guide rod 311 is a rectangular long rod structure, the side plate 21 is provided with a groove body 211, the axial ends of the guide rod 311 are respectively inserted into the groove body 211, and the axial ends of the guide rod 311 can move up and down along the inner wall of the groove body 211 ( Figure 1 , Figure 2 The cylinder 312 is a cylindrical structure, and the guide rod 311 passes through the cylinder 312. The two axial ends of the guide rod 311 extend out of the cylinder 312 and are inserted into the groove body 211. The cylinder 312 is equipped with a plug rod 314, which is threadedly connected and inserted into the inner wall of the cylinder 312. The plug rod 314 is axially arranged along the radial direction of the cylinder 312, and the plug rod 314 extends inward along the radial direction of the cylinder 312. The plug rod 314 is sleeved with a spring 315, one end of the spring 315 abuts against the inner wall of the cylinder 312, and the other end abuts against the guide rod 311. The cylinder 1 312 is provided with a groove 3121, which is recessed and extends radially outward along the inner wall of the cylinder 1 312. The length direction of the groove 3121 is arranged along the axial direction of the guide rod 1 311. The guide rod 1 311 is inserted into the groove 3121 away from the side of the spring 1 315. The guide rod 1 311 can move left and right along the inner wall of the groove 3121 ( Figure 1 , Figure 2 The width of the guide rod 1 311 is the same as the width of the slot body 3121. Under the action of the spring 1 315, the side of the guide rod 1 311 away from the spring 1 315 abuts against the inner wall of the slot body 3121, so that when the guide rod 1 311 moves up and down ( Figure 1 , Figure 2 As shown in the figure), the guide rod 311 can drive the cylinder 312 to move synchronously.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, moving rods 331 are installed on both sides of the guide rod 311, and the moving rod 331 is installed with screws 33, which pass through the cover plate 2 and the moving rod 331, and the screws 33 and the moving rod 331 are spirally driven, and the screws 33 are driven to rotate by the motor 332 and can drive the moving rod 331 to move up and down, thereby driving the guide rod 311 to move up and down. The side plate 21 is installed with a guide rail 6, and the moving rod 331 is slidably connected to the guide rail 6.

[0028] like Figure 3As shown, the moving rod 1 331 is slidably connected with the cylinder 1 312. The moving rod 1 331 includes an extension rod 3311, which passes through the cylinder 1 312 and is threadedly connected to be inserted into the guide rod 1 311, so that the cylinder 1 312 cannot rotate, so as to prevent the guide rod 1 311 and the slot 3 3121 from being misaligned in the disengaged state, resulting in the guide rod 1 311 being unable to be inserted into the slot 3 3121.

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

[0030] like Figure 1-Figure 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 the cylinder 1 312 away from the other cylinder 1 312. The push block 35 can move toward the side close to the cylinder 1 312 to push the cylinder 1 312, so that the two cylinders 1 312 are close to each other. When the push block 35 moves to the side away from the cylinder 1 312 to loosen the cylinder 1 312, the two cylinders 1 312 are separated from each other under the action of the spring 1 315. Through the action of the push block 35, the two cylinders 1 312 are constantly close to and away from each other, driving the fabric 4 to move, so that the scouring liquid impacts the fabric 4, thereby facilitating the removal of impurities in the fibers of the fabric 4, so as to improve the process efficiency. At the same time, the movement of the fabric 4 can enhance the flow of the scouring liquid, so that the concentration of the effective component (NaOH) in the scouring liquid near the fabric 4 is increased, thereby improving the reaction efficiency.

[0031] like Figure 2As shown, the structure of component 2 32 is similar to component 1 31, and 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, and guide rod 2 321 extends out of cylinder 2 322 at both ends in the axial direction, and outer cylinder 2 323 is sleeved on the outer wall of cylinder 2 322. Side plate 21 is also provided with groove 212, which is arranged parallel to groove 1 211, and guide rod 2 321 is inserted into groove 212 at both ends in the axial direction, and guide rod 2 321 can move up and down along the inner wall of groove 212. Moving rod 2 341 is installed at both ends of guide rod 2 321, and moving rod 2 341 is spirally connected with screw 2 34, screw 2 34 passes through moving rod 2 341, and screw 2 34 is driven to rotate by motor 2 342 to achieve up and down movement. A plurality of second plug rods 324 are fixedly installed on the inner wall of the second cylinder 322. The second plug rods 324 are distributed along the axial direction of the second cylinder 322. The second plug rods 324 are sleeved with a second spring 325. One end of the second spring 325 abuts against the inner wall of the second cylinder 322, and the other end abuts against the second guide rod 321. The second guide rod 321 is slidably connected and inserted into the second cylinder 322 away from the second spring 325, and the insertion direction is along the up-down direction, so that the second cylinder 322 can move synchronously with the second guide rod 321. When the two cylinders 1 312 in the same moving unit 3 are in a state of being away from each other, the second spring 325 is in a compressed state. Therefore, by setting the second spring 325, when the two cylinders 1 312 in the same moving unit 3 are close to each other and drive the fabric 4 to gather inward, due to the weakening of the tension of the fabric 4, the second spring 325 can timely push the second outer cylinder 323 downward to prevent the fabric 4 from loosening, which helps the scouring liquid to form a better impact on the fabric 4.

[0032] like Figure 1 As shown, the side plate 21 is installed 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, the cover plate 2 is lifted upward, and the outer cylinder 1 313 is moved to the lower position. The outer cylinder 2 323 can remain in the lower position and move the fabric 4 around the bottom of the two rollers 5, and then the outer cylinder 1 313 is moved upward. The outer cylinder 1 313 bends the fabric 4 to form a folded path during the upward movement to increase the contact area between the fabric 4 and the scouring liquid and prevent the fabric 4 from piling up and affecting the reaction efficiency. For the operator, the installation position of the fabric 4 can be lifted to a high place, which is very convenient.

[0034] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
