[0015] This invention also provides a process for producing all-cotton spunlace nonwoven fabric, applied to a wastewater treatment device for all-cotton spunlace nonwoven fabric. The process for producing all-cotton spunlace nonwoven fabric includes the following steps:

[0016] Step S1: Place the roller frame for winding the fabric on the tray and lock it in place using the docking mechanism. As more fabric is wound up, its weight will increase, pressing the tray downwards. When the tray slides down to the bottom, the limiting component will be triggered to limit the sliding ring, and the drainage component will be triggered to drain the water from the area where the fabric is wound.

[0017] Step S2: When the limiting component is working, the sliding ring will press the annular ring downwards during the downward sliding process. When the annular ring slides downwards, the mutual engagement of the guide and the guide block can drive the annular sleeve to rotate, which in turn drives the connecting ring to rotate. When the connecting ring rotates, the slider can slide towards the end of the locking block, pushing one side of the locking block into the inside of the fixed sleeve, thereby pressing and limiting the sliding ring.

[0018] Step S3: When the drainage component is working, when the locking block pushes out into the fixed sleeve from one side, one end of the locking block will fit against one side of the contact block, thereby pressing the contact block into the receiving groove, which in turn drives the connecting rod and the lever to slide to one side. During the sliding of the lever to one side, the bottom of the through hole will be opened, allowing water to flow through.

[0019] Step S4: When the docking mechanism is working, as the lever slides to one side, one end of the lever is in contact with the bottom of the spring plate, which pushes the bottom line of the spring plate to one side, thereby causing the top of the spring plate to open in the opposite direction, thus releasing the constraint on the inner side of the roller frame for winding the fabric.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, the roller frame for winding the fabric is placed on a tray and locked in place by a docking mechanism, so that the fabric is inside a pool filled with water. At this time, the fuzz on the surface of the fabric is floating. Winding the fabric at this time will flatten the fuzz on the fabric in the winding direction, thus avoiding the problem of fuzz on the fabric agglomerating after dehydration.

[0022] 2. In this invention, during the downward sliding of the sliding ring, the annular ring will be pressed downward. When the annular ring slides downward, the mutual engagement of the guide and the guide block can drive the annular sleeve to rotate, thereby causing the connecting ring to rotate. When the connecting ring rotates, the slider can slide towards the end of the locking block, pushing one side of the locking block into the interior of the fixed sleeve, thereby pressing and limiting the sliding ring.

[0023] 3. In this invention, when the card block is pushed into the fixed sleeve from one side, one end of the card block will fit against one side of the contact block, thereby pressing the contact block into the storage groove, which in turn drives the connecting rod and the lever to slide to one side. During the sliding of the lever to one side, the bottom of the through hole will be opened, allowing water to flow through.

[0024] 4. In this invention, when the lever is slid to one side, since one end of the lever is in contact with the bottom of the spring plate, the bottom line of the spring plate will be pushed to one side, thereby causing the top of the spring plate to open in the opposite direction, thus releasing the constraint on the inner side of the roller frame for winding the fabric.

Detailed Implementation

[0034] 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.

[0035] Please see Figure 1-8 The present invention provides a technical solution: a wastewater treatment device for all-cotton spunlace nonwoven fabric, including a water tank 1, a partition 6 between the inner walls of the front and rear sides of the water tank 1, a fixing sleeve 4 near one edge of the bottom of the water tank 1, the top of the fixing sleeve 4 communicating with the interior of the water tank 1, a sliding ring 15 between the inner walls of the fixing sleeve 4, a docking mechanism at the top of the sliding ring 15, and drainage components near both edges of the interior of the sliding ring 15.

[0036] An annular cavity 29 is provided inside the fixed sleeve 4 near the bottom edge. The bottom of the annular cavity 29 extends into the interior of the fixed sleeve 4 near one side edge. A limit component is provided inside the annular cavity 29. An end cap 5 is provided at the bottom of the fixed sleeve 4. A motor 9 is provided inside the end cap 5. A hexagonal rod 10 is provided at the output end of the motor 9. The top of the hexagonal rod 10 extends into the interior of the water tank 1. A pad 3 is provided at the bottom of the water tank 1. Water inlet pipes 2 are connected to both sides of the water tank 1. Two water outlet pipes 7 are connected to the rear side of the water tank 1. A partition 6 divides the water tank 1 into two areas. The fixed sleeve 4 is located on one side of the partition 6.

[0037] The desired effect is as follows: the fabric winding roller frame is placed on the tray 8 and secured by the docking mechanism. The fabric is then wound up by the roller frame. As more fabric is wound up, its weight increases, pressing the tray 8 downwards. When the tray 8 slides to the bottom, a limiting component is triggered to limit the sliding ring 15. The limiting component also triggers a drainage component to drain water from the fabric winding area, simultaneously releasing the limiting effect of the docking mechanism on the fabric winding roller frame. Dividing the water tank 1 into two areas ensures that the fabric is rinsed with water before winding, thus cleaning the fabric surface. The lint on the fabric is dispersed and opened up. The rinsed water is discharged in time through the drain pipe 7, which facilitates the subsequent water flow to repeat the above-mentioned treatment of the fabric. Setting the rinsing area at the fabric winding position can avoid the water source of the water tank 1 located on the other side of the partition 6 being contaminated. At the same time, separating the water tank 1 makes it easier to supply water to the winding area. After rinsing, the wastewater is discharged in time through the drain pipe 7, which can prevent the wastewater after rinsing from being discharged in time and easily contaminating the non-woven fabric in subsequent rinsing processes. At the same time, the newly introduced water source is easily contaminated again, resulting in the waste of water resources and saving water for the entire production process.

[0038] like Figure 4 , Figure 6 and Figure 7As shown, the limiting assembly includes a connecting ring 30, which is slidably disposed on the inner bottom surface of the annular cavity 29. The inner side of the connecting ring 30 extends into the interior of the fixing sleeve 4. An annular sleeve 37 is slidably fitted between the inner walls of the fixing sleeve 4. The bottom of the annular sleeve 37 is fixed to the top of the connecting ring 30. An annular ring 35 is slidably disposed between the inner walls of the annular sleeve 37. Multiple guide channels 38 are equidistantly opened along the circumferential direction on the inner wall of the annular sleeve 37. Guide blocks 36 are slidably engaged inside the multiple guide channels 38. The multiple guide blocks 36 are correspondingly fixed to the outer surface of the annular ring 35. A lifting spring 39 is fixed to the bottom of the annular ring 35. The bottom of the lifting spring 39 is fixed to the fixing sleeve 4. On the inner bottom surface, two uprights 32 are fixed to the top of the connecting ring 30. Both uprights 32 are located inside the annular cavity 29. Slider 31 is fixed to the top of each of the two uprights 32. Constraint grooves 40 are provided on both sides of the inner wall of the annular cavity 29. One side of each of the two sliders 31 is correspondingly slidably engaged inside the constraint groove 40. Openings 33 are provided on both sides of the inner wall of the fixing sleeve 4. Both openings 33 extend into the interior of the constraint groove 40. The interior of each of the two openings 33 is rotatably connected to a locking block 34 via a torque shaft. One end of each of the two sliders 31 and one end of each locking block 34 are inclined. The inclined surface of one end of the locking block 34 is in contact with the inclined surface of one end of the slider 31.

[0039] The effect achieved is that as the sliding ring 15 slides downward, it presses the annular ring 35 downward. When the annular ring 35 slides downward, the mutual engagement of the guide rail 38 and the guide block 36 drives the annular sleeve 37 to rotate, which in turn drives the connecting ring 30 to rotate. When the connecting ring 30 rotates, the slider 31 can slide towards the end of the locking block 34, pushing one side of the locking block 34 into the interior of the fixed sleeve 4, thereby pressing and limiting the sliding ring 15. During the rotation and downward movement of the annular ring 35, the lifting spring 39 is in a compressed state and has a certain torsional torque, thus ensuring that the annular ring 35 can be slightly rotated at a certain angle during the upward lifting process when resetting, thereby driving the annular sleeve 37 to reset and thus releasing the constraint on the sliding ring 15.

[0040] like Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the drainage assembly includes a deflector plate 20, a pressure ring 28 fixed to the bottom of the sliding ring 15, the bottom of the pressure ring 28 slidingly fitting against the top of the annular ring 35, an annular limiting opening 16 on the outer surface of the sliding ring 15, a limiting ring 17 fixed to the inner wall of the fixing sleeve 4, the limiting ring 17 slidingly engaging inside the annular limiting opening 16, an adjusting cavity 21 inside the sliding ring 15, a guide opening 22 at the top of the adjusting cavity 21, a guide groove 19 near the top edge of the outer surface of the sliding ring 15, the top of the guide opening 22 penetrating into the interior of the guide groove 19, a deflector plate 20 slidably connected between the inner walls of the guide groove 19, and two drain holes 11 on the outer surfaces of both sides of the fixing sleeve 4. One end of the sliding ring 15 extends into the interior of the fixed sleeve 4. A storage groove 24 is provided on the outer surface of the sliding ring 15 near the bottom edge. A contact block 27 is slidably connected between the inner walls of the storage groove 24. A push rod 25 is fixed on one side of the contact block 27. One end of the push rod 25 slides through into the interior of the adjustment cavity 21. A reciprocating spring 26 is fixed on one side of the contact block 27. One end of the reciprocating spring 26 is fixed on the inner wall of one side of the storage groove 24. A connecting rod 23 is fixed on one end of the push rod 25. The connecting rod 23 is located inside the guide port 22. The top of the connecting rod 23 is fixed to the bottom of the dial plate 20. A through hole 18 is provided on the top of the sliding ring 15 near the outer edge of the surface. The through hole 18 extends into the interior of the guide groove 19.

[0041] The effect is that when the locking block 34 is pushed into the fixed sleeve 4, one end of the locking block 34 will fit against one side of the contact block 27, thereby pressing the contact block 27 into the storage groove 24, which in turn drives the connecting rod 23 and the lever 20 to slide to one side. During the sliding of the lever 20 to one side, the bottom of the through hole 18 will be opened, allowing water to flow through. At this time, the reciprocating spring 26 is in a compressed state.

[0042] like Figure 4 and Figure 5 As shown, the docking mechanism includes a tray 8, which is rotatably connected to the top of the sliding ring 15 and slidably connected to the outer surface of the hexagonal rod 10. Multiple water-passing mesh openings 12 are equidistantly spaced along the circumferential direction near the edge of the outer surface of the top of the tray 8. A through hole 18 is located directly below the water-passing mesh opening 12. The bottom of the tray 8 is in contact with the top of the sliding ring 15. A notch 13 is provided on the top of the tray 8, and an annular opening 41 is provided on the top of the sliding ring 15. The annular opening 41 is connected to one end of the guide groove 19. The bottom of the notch 13 extends into the interior of the annular opening 41. A spring-loaded plate 14 is rotatably connected between the inner walls of the two sides of the notch 13. The bottom of the spring-loaded plate 14 extends into the interior of the annular opening 41 and is in contact with one end of the lever 20. The hook end of the top of the spring-loaded plate 14 extends above the tray 8.

[0043] The effect achieved is that when the lever 20 slides to one side, since one end of the lever 20 is in contact with the bottom of the spring clamp 14, the bottom line of the spring clamp 14 will be pushed to one side, thereby causing the top of the spring clamp 14 to open in the opposite direction, thus releasing the constraint on the inner side of the roller frame for winding the fabric.

[0044] The main problem solved in this embodiment is: placing the roller frame for winding the fabric on the tray 8 and locking it in place by the docking mechanism, so that the fabric is inside the pool filled with water. At this time, the fuzz on the surface of the fabric is floating. Winding the fabric at this time will flatten the fuzz on the fabric in the winding direction, avoiding the problem of fuzz on the fabric gathering after dehydration. Then, as more fabric is wound up, its own weight will also increase, thus pressing the tray 8 downward. When the tray 8 slides down to the bottom position, it will trigger the limiting component to limit the sliding ring 15. When the limiting component is working, it will trigger the drainage component to drain the water in the area where the fabric is wound up, and at the same time release the limiting effect of the docking mechanism on the roller frame for winding the fabric.

[0045] For example, in one embodiment, the present invention also provides a process for producing all-cotton spunlace nonwoven fabric, applied to the above-mentioned all-cotton spunlace nonwoven fabric wastewater treatment equipment, including the following steps:

[0046] Step S1: Place the roller frame for winding the fabric on the tray 8 and lock it in place using the docking mechanism. As more fabric is wound up, its weight will increase, pressing the tray 8 downwards. When the tray 8 slides down to the bottom position, the limiting component will be triggered to limit the sliding ring 15, and the drainage component will be triggered to drain the water from the area where the fabric is wound.

[0047] Step S2: When the limiting component is working, the sliding ring 15 will press the annular ring 35 downward as it slides downward. When the annular ring 35 slides downward, the mutual engagement of the guide 38 and the guide block 36 will drive the annular sleeve 37 to rotate, which will drive the connecting ring 30 to rotate. When the connecting ring 30 rotates, the slider 31 can slide towards the end of the locking block 34, pushing one side of the locking block 34 into the interior of the fixed sleeve 4, thereby pressing and limiting the sliding ring 15.

[0048] Step S3: When the drainage component is working, when the locking block 34 pushes out into the fixed sleeve 4 from one side, one end of the locking block 34 will fit against one side of the contact block 27, thereby pressing the contact block 27 into the receiving groove 24, which in turn drives the connecting rod 23 and the lever 20 to slide to one side. During the sliding of the lever 20 to one side, the bottom of the through hole 18 will be opened, allowing water to flow through.

[0049] Step S4: When the docking mechanism is working, when the lever plate 20 slides to one side, since one end of the lever plate 20 is in contact with the bottom of the spring clamp plate 14, the bottom line of the spring clamp plate 14 will be pushed to one side, thereby causing the top of the spring clamp plate 14 to open in the opposite direction, thereby releasing the constraint on the inner side of the roller frame of the winding fabric.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
