Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing equipment technology, and in particular to a dyeing device for chemical fiber fabrics. Background Technology

[0002] Dyeing refers to the process of coloring substances using chemical or physical methods. It is mainly used in the treatment of textile materials. Dyes combine with fibers through chemical or physicochemical processes to form colored substances with acceptable color fastness. The dyeing process can be carried out in separate baths or in the same bath. Different fibers need to use dyes with basically the same color fastness. Chemical fiber fabrics are one of the fabrics that can be dyed. Chemical fiber is also known as "chemical fiber". It refers to fiber materials that are processed by chemical methods. It is different from "natural fibers" such as cotton, linen, silk, and wool. It is widely used in clothing, home textiles, industrial products and other fields.

[0003] Traditionally, dyeing synthetic fiber fabrics is done in a dyeing box. The dyeing box typically has conveyor rollers and pressure rollers at both the inlet and outlet, and a pressure roller is installed at the bottom inside the box, positioned between the conveyor and pressure rollers. The pressure roller presses the fabric passing through the conveyor rollers into the dyeing box, allowing the fabric to be soaked in the dye. A flow-through pipe with a filter screen is usually installed at the bottom of the dyeing box. After a period of use, some lint and impurities accumulate inside the dyeing box, requiring cleaning. Generally, the flow-through pipe is opened to allow the dye to flow out, leaving the impurities inside the dyeing box for cleaning by personnel. Then, the dye is poured back into the dyeing box.

[0004] However, cleaning impurities inside the dyeing box is time-consuming, laborious, and inconvenient, and it affects the overall dyeing efficiency. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dyeing device for chemical fiber fabrics.

[0026] like Figures 1 to 7As shown, a dyeing device for chemical fiber fabrics includes a support box 1 and a dyeing box 2 horizontally disposed inside it. A feeding assembly 3 for conveying the fabric is disposed on the upper side of the support box 1. A flow pipe is provided at the lower end of the support box 1 for the flow of impurity water. The feeding assembly 3 adopts the technical equipment commonly used by those skilled in the art. The middle of the left and right ends of the dyeing box 2 is rotatably connected to the support box 1 through a rotating rod 4. A through hole 5 is opened on the dyeing box 2, and two sets of bottom plates 6 are arranged parallel to each other in the through hole 5. The two sets of bottom plates 6 are arranged opposite each other, and a receiving cavity 7 is formed between the two sets of bottom plates 6. A connecting pipe 8 is arranged opposite each other in the receiving cavity 7. Both ends of the connecting pipe 8 are open and extend out of the receiving cavity 7, and a filter screen 9 is embedded and fixed in both ends. A cuboid block 10 is slidably disposed outside the receiving cavity 7 inside the dyeing box 2. Two sets of blocks 10 are provided, each opposite to one of the two sets of bottom plates 6. A cavity 11 is opened inside the block 10, and the block 10 faces the bottom. A nozzle 12 communicating with the cavity 11 is provided on one side of the plate 6. Several groups of nozzles 12 are arranged along the length and width of the baffle 10. A delivery pump 13 is provided inside the receiving cavity 7. The output end of the delivery pump 13 is connected to a reversing valve (not shown in the attached figure). The reversing valve has one inlet end and two outlet ends. Each of the two outlet ends is connected to a telescopic pipe 14. The telescopic pipe 14 is located outside the receiving cavity 7 and is connected to the outer wall of the bottom plate 6. The telescopic pipe 14 communicates with the inside of the cavity 11. The inlet end of the dyeing box 2 is connected to a water supply pipe 26. There are rotating rods 4 at both ends of the dyeing box 2. One set of rotating rods 4 is connected to a motor, and the other set of rotating rods 4 is hollow and rotatably connected to the inner wall of the support box 1. One end of the water supply pipe 26 passes through the hollow rotating rod 4 and is located outside the support box 1, and is connected to a water tank 25. A rotary joint 27 is installed on the straight pipe of the water supply pipe 26, so that when the dyeing box 2 rotates, the water supply pipe 26 will not be rotated as a whole, causing structural interference.

[0027] Inside the dyeing box 2, at both the upper and lower ends, there are U-shaped plates 15 parallel to the stop block 10. The inner wall dimensions of the U-shaped plates 15 are smaller than those of the stop block 10, so that when the stop block 10 is blocked and limited by the U-shaped plates 15, the opening of the through hole 5 of the dyeing box 2 is blocked. The bottom plate 6 is connected to the stop block 10 through a telescopic air cover 16. An air pump 17 is installed inside the receiving cavity 7. In this embodiment, several sets of telescopic air covers 16 are provided, such as... Figure 3As shown, the air pump 17 has two sets of output terminals located at the four ends of the receiving cavity 7, and each set is connected to a reversing valve 2 (not shown in the attached figure). The reversing valve 2 has one inlet end and two outlet ends. The inlet end is connected to the output end of the air pump 17, and each of the two outlet ends is connected to a main pipe (not shown in the attached figure). Several sets of branch pipes (not shown in the attached figure) are provided on the main pipe, which are respectively connected to each set of telescopic air hoods 16. A rotating rod 18 is horizontally rotatable along its length inside the receiving cavity 7. A winding reel 19 is provided on the rotating rod 18, and a connecting strip 20 is wound on the winding reel 19. One end of the connecting strip 20 passes through the bottom plate 6 and is connected to the stop block 10. In this embodiment, there are four sets of rotating rods 18, distributed at the four ends inside the receiving cavity 7, arranged in pairs opposite each other. The connecting strip 20 of the winding reel 19 on the two sets of rotating rods 18 located on the same horizontal plane is connected to a stop block 10. Block 10 is connected to two sets of rotating rods 18 located on the same horizontal plane. One set is connected to the motor 21, and the other set is driven by a linkage structure. The linkage structure includes a drive wheel and a linkage rod, each set on the outer wall of the two sets of rotating rods 18. The two ends of the linkage rod are provided with linkage wheels that mesh with the drive wheel. The purpose is that when one set of the two sets of rotating rods 18 on the same horizontal plane is driven by the motor 21, the other set will be linked synchronously. A telescopic cover 22 is provided on the outside of the end of the connecting belt 20 that passes through the bottom plate 6. One end of the telescopic cover 22 is connected to the stop block 10, and the other end is connected to the outer wall of the bottom plate 6. A bracket 23 is provided inside the receiving cavity 7. A roller 24 is horizontally arranged on the bracket 23. One end of the connecting belt 20 passes through the bottom plate 6 around the roller 24. The purpose is to avoid the connecting belt 20 directly contacting and rubbing against the part of the bottom plate 6 through which it passes.

[0028] A cylinder 28 is vertically fixed on the upper side of the outer wall of the support box 1. A fixed frame 29 is provided at the top of the piston rod of the cylinder 28. Guide rollers 30 are horizontally rotated at both ends of the fixed frame 29. The fixed frame 29 is pushed down by the cylinder 28, and the fixed frame 29 drives the guide rollers 30 to move down, pressing the fabric on the support box 1 into the dyeing box 2 for dyeing.

[0029] In this embodiment, the outer wall of the base plate 6 is provided with an inner groove (not shown in the figure) for one end of the telescopic tube 14, the telescopic air cover 16, and the telescopic cover 22 to be inserted and connected. A U-shaped sealing ring 31 is embedded in the outer wall of the base plate 6, and a sealing ring 32 is embedded in the inner wall of the U-shaped plate 15. The length and width of the sealing ring 31 and the sealing ring 32 are both smaller than the length and width of the stop block 10.

[0030] When dyeing synthetic fiber fabrics, the dyeing box 2 has the dye-containing side facing upwards, and its through hole 5 is located directly below the feeding assembly 3. The cylinder 28 is in the extended state, and the guide roller 30 presses the fabric down into the dyeing box 2. The two sets of rotating rods 18 located on the same horizontal plane above and below the receiving cavity 7 pull the connecting strip 20 on the reel 19, which sticks the connected block 10 to the bottom plate 6. Through the sealing ring 31, the dye does not flow into the connecting pipe 8, and the air pump 17 and the conveying pump 13 are both in the stopped state.

[0031] When there are too many lint and impurities in the dye, cylinder 28 first retracts, moving guide roller 30 upwards, and the fabric moves upwards and out of dyeing box 2. Then, the rotating rod 18 located below the receiving cavity 7 is driven by motor 21, causing the connecting belt 20 to loosen, the stop block 10 to no longer adhere to the bottom plate 6, the air pump 17 starts working, and the reversing valve 2 closes the upper outlet end. Gas will enter the lower telescopic air cover 16 through the reversing valve 2, pushing the lower stop block 10 away from the bottom plate 6 and adhering to the lower U-shaped block. At this time, a closed space is formed below. Then the reversing valve 2 opens. The lower outlet is closed and the upper outlet is opened. The upper baffle 10 also begins to move away from the bottom plate 6. At this time, the dye in the upper part of the dyeing box 2 begins to pass through the connecting pipe 8. Fiber impurities will be blocked by the filter screen 9 on the flow pipe. The filtered dye enters the closed space formed below the dyeing box 2. After the flow is completed, the reversing valve 2 resets and closes the upper outlet again. It should be noted that the output end of the air pump 17 has the function of internal air intake and air exhaust. Therefore, before the reversing valve 2 closes, the air pump 17 will draw gas from the upper telescopic air cover 16. To a certain extent, the upper rotating rod 18, driven by the motor 21, moves the stop block 10 to adhere to the bottom plate 6 via the connecting belt 20. Then, the dyeing box 2 begins to rotate up and down, moving the enclosed space containing the filtered dye to the top. After the rotation is complete, the air pump 17 draws a certain amount of gas from the upper telescopic air hood 16. Then, the upper rotating rod 18, driven by the motor 21, moves the stop block 10 to adhere to the bottom plate 6 via the connecting belt 20. At this point, both bottom plates 6 are held in place by two sets of stop blocks 10, located at the bottom. The telescopic air hood 16 begins to extend by the air pump 17, and the rotating rod 18 below works in conjunction to prevent the lower stop block 10 from adhering to the base plate 6. The delivery pump 13 also begins to pump water from the water tank 25, and the upper outlet end is closed and the lower outlet end is opened under the control of the reversing valve 1, allowing water to flow into the cavity 11 inside the lower stop block 10. The spray nozzle 12 begins to spray water to rinse the outer wall of the base plate 6 located below, and also to rinse the surface of the filter screen 9 at the lower end of the connecting pipe 8. Meanwhile, the dyeing of chemical fiber fabrics continues above the dyeing box 2.

[0032] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
