[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention places the roller frame for rolling up the cloth on the tray and fixes it by a docking mechanism, so that the cloth is placed inside a pool filled with water. At this time, the fluff on the surface of the cloth is in a floating state. At this time, rolling up the cloth will flatten the fluff on the cloth along the rolling direction, thus avoiding the problem of the fluff on the cloth gathering after dehydration; 2. In the present invention, the annular ring is pressed downwards during the downward sliding process of the sliding ring. When the annular ring slides downwards, the guideway and the guide block engage with each other, thereby driving the annular sleeve to rotate, thereby driving the connecting ring to rotate. When the connecting ring rotates, the slider can slide toward one end of the block, and one side of the block can be pushed out toward the inside of the fixed sleeve, thereby pressing and limiting the sliding ring. 3. In the present invention, when one side of the card block is pushed out toward the inside of the fixing sleeve, one end of the card block will fit with one side of the contact block, thereby pressing the contact block toward the inside of the storage groove, thereby driving the connecting rod and the paddle to slide toward one side. During the sliding process of the paddle to slide toward one side, the bottom of the through hole will be opened, allowing water to pass through; 4. In the present invention, when the paddle is slid to one side, since one end of the paddle is in contact with the bottom of the spring clamp, the bottom line of the spring clamp is pushed to one side, and then the top of the spring clamp is opened in the opposite direction, thereby releasing the constraint on the inner side of the drum frame for winding the fabric.

DETAILED DESCRIPTION

[0018] 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 implementation regulations described 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.

[0019] See also Figure 1-8 The present invention provides a technical solution: a cotton spunlace non-woven wastewater treatment device, comprising a water tank 1, a partition 6 is arranged between the inner walls of the front and rear sides of the water tank 1, a fixing sleeve 4 is arranged at the bottom of the water tank 1 near one side edge, the top of the fixing sleeve 4 is connected to the inside of the water tank 1, a sliding ring 15 is arranged between the inner walls of the fixing sleeve 4, a docking mechanism is arranged at the top of the sliding ring 15, and drainage components are arranged inside the sliding ring 15 near the edges of both sides; An annular cavity 29 is provided inside the fixing sleeve 4 near the bottom edge, and the bottom of the annular cavity 29 passes through the inside of the fixing sleeve 4 near the edge of one side, and a limiting component is arranged inside the annular cavity 29. An end cover 5 is arranged at the bottom of the fixing sleeve 4, and a motor 9 is arranged inside the end cover 5. A hexagonal rod 10 is arranged at the output end of the motor 9, and the top of the hexagonal rod 10 passes through the inside of the water tank 1. A pad 3 is arranged at the bottom of the water tank 1. Both sides of the water tank 1 are connected with water inlet pipes 2, and the back side of the water tank 1 is connected with two water outlet pipes 7. The partition 6 divides the water tank 1 into two areas, and the fixing sleeve 4 is located on one side of the partition 6.

[0020] The effect achieved is that the roller frame for winding the cloth is placed on the tray 8, which is fixed by the docking mechanism, and then the cloth is wound by the roller frame. As the wound cloth increases, its own weight will increase accordingly, thereby pressing the tray 8 downward. When the tray 8 slides downward to the bottom position, the limiting component will be triggered to limit the sliding ring 15. When the limiting component works, the drainage component will be triggered to discharge the water flow in the wound cloth area, and at the same time, the limiting effect of the docking mechanism on the roller frame for winding the cloth is released. Dividing the water tank 1 into two areas can ensure that the cloth is rinsed with water before winding, and the surface of the cloth is cleaned. The fluff on the surface is dispersed and opened, and the water after rinsing is discharged in time through the outlet pipe 7, which is convenient for the subsequent water flow to enter and repeat the above-mentioned processing method for the cloth. The rinsing area is set at the cloth winding position, which can prevent the water source on the other side of the partition 6 from being contaminated by the water tank 1. At the same time, the water tank 1 is separated to facilitate the supply of water to the winding area. After rinsing, the sewage is discharged in time through the outlet pipe 7 to avoid the sewage after rinsing not being discharged in time. It is easy to pollute the non-woven fabric in the subsequent rinsing process. At the same time, the newly entered water source is easily polluted for the second time, resulting in a waste of water, saving water for the entire production process.

[0021] like Figure 4 , Figure 6 and Figure 7 As shown, the limiting assembly includes a connecting ring 30, which is slidably arranged on the inner bottom surface of the annular cavity 29, and the inner side of the connecting ring 30 extends to the inside of the fixing sleeve 4. An annular sleeve 37 is slidably fitted between the inner walls of the fixing sleeve 4, and the bottom of the annular sleeve 37 is fixed to the top of the connecting ring 30. An annular ring 35 is slidably arranged between the inner walls of the annular sleeve 37, and the inner wall of the annular sleeve 37 is equidistantly provided with a plurality of guide channels 38 along the circumferential direction. The interiors of the plurality of guide channels 38 are all slidably engaged with guide blocks 36, and the plurality of guide blocks 36 are correspondingly fixed on the outer surface of the annular ring 35. A lifting spring 39 is fixed to the bottom of the annular ring 35, and the bottom of the lifting spring 39 is fixed to the fixing sleeve 4. On the inner bottom surface, two vertical rods 32 are fixed on the top of the connecting ring 30, and the two vertical rods 32 are both located inside the annular cavity 29. Sliders 31 are fixed on the tops of the two vertical rods 32. Constraint grooves 40 are provided on the inner walls on both sides of the annular cavity 29. One side of the two slides 31 is correspondingly slidably engaged in the inside of the constraint groove 40. Openings 33 are provided on the inner walls on both sides of the fixed sleeve 4. The two openings 33 are correspondingly penetrated into the inside of the constraint groove 40. The insides of the two openings 33 are rotatably connected with blocks 34 through the torque shaft. One end of the two slides 31 and one end of the two blocks 34 are both inclined, and the inclined surface of one end of the block 34 fits with the inclined surface of one end of the slide 31.

[0022] The effect achieved is that the annular ring 35 will be pressed downward during the downward sliding process of the sliding ring 15. When the annular ring 35 slides downward, the guide path 38 and the guide block 36 engage with each other, thereby driving the annular sleeve 37 to rotate, thereby driving the connecting ring 30 to rotate. When the connecting ring 30 rotates, the slider 31 can slide toward one end of the block 34, and one side of the block 34 is pushed out toward the inside of the fixed sleeve 4, thereby pressing and limiting the sliding ring 15. During the process of the annular ring 35 rotating and sliding down, the lifting spring 39 is in a compressed state and has a certain torsional torque, thereby ensuring that the annular ring 35 can be slightly rotated a certain angle during the upward lifting process when resetting, thereby driving the annular sleeve 37 to reset, thereby releasing the constraint on the sliding ring 15.

[0023] like Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the drainage assembly includes a paddle 20, a pressure ring 28 is fixed at the bottom of the sliding ring 15, the bottom of the pressure ring 28 is slidably fitted with the top of the annular ring 35, an annular limit opening 16 is provided on the outer surface of the sliding ring 15, a limit ring 17 is fixed on the inner wall of the fixed sleeve 4, the limit ring 17 is slidably engaged in the inside of the annular limit opening 16, an adjustment cavity 21 is provided inside the sliding ring 15, a conducting opening 22 is provided at the top of the adjusting cavity 21, a guide groove 19 is provided on the outer surface of the sliding ring 15 near the top edge, the top of the conducting opening 22 penetrates into the inside of the guide groove 19, the paddle 20 is slidably connected between the inner walls of the guide groove 19, and drainage holes 11 are provided on the outer surfaces of both sides of the fixed sleeve 4, and the two drainage holes One end of 11 penetrates into the interior of the fixed sleeve 4, a receiving groove 24 is opened 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 receiving groove 24, a push rod 25 is fixed on one side of the contact block 27, one end of the push rod 25 slides and penetrates into the interior of the adjusting chamber 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 one side of the inner wall of the receiving groove 24, a connecting rod 23 is fixed on one end of the push rod 25, the connecting rod 23 is located inside the conducting port 22, the top of the connecting rod 23 is fixed to the bottom of the dial plate 20, a through hole 18 is opened on the top of the sliding ring 15 near the edge of the outer surface, and the through hole 18 penetrates into the interior of the guide groove 19.

[0024] The effect achieved is that when one side of the block 34 is pushed out toward the inside of the fixing sleeve 4, one end of the block 34 will fit with one side of the contact block 27, thereby pressing the contact block 27 toward the inside of the receiving groove 24, thereby driving the connecting rod 23 and the paddle plate 20 to slide to one side. When the paddle plate 20 slides to one side, the bottom of the through hole 18 will be opened to allow water to pass through. At this time, the reciprocating spring 26 is in a compressed state.

[0025] 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 the tray 8 is slidably connected to the outer surface of the hexagonal rod 10. A plurality of water-passing mesh openings 12 are equidistantly provided at the top of the tray 8 near the edge of the outer surface along the circumferential direction, and the through hole 18 is located directly below the water-passing mesh openings 12. The bottom of the tray 8 fits with the top of the sliding ring 15, and a recess 13 is provided on the top of the tray 8. An annular opening 41 is provided on the top of the sliding ring 15, and the annular opening 41 is communicated with one end of the guide groove 19. The bottom of the recess 13 penetrates into the interior of the annular opening 41, and a spring clip 14 is rotatably connected between the inner walls on both sides of the recess 13. The bottom of the spring clip 14 extends to the interior of the annular opening 41 and fits with one end of the dial plate 20, and the top hook end of the spring clip 14 extends to the top of the tray 8.

[0026] The effect achieved is that when the paddle 20 slides to one side, since one end of the paddle 20 fits against the bottom of the spring clamp 14, the bottom line of the spring clamp 14 is pushed to one side, and then the top of the spring clamp 14 is opened in the opposite direction, thereby releasing the constraint on the inner side of the drum frame for winding the fabric.

[0027] The main problem solved by this embodiment is: the roller frame for rolling up the cloth is placed on the tray 8, and it is fixed by the docking mechanism, so that the cloth is inside the pool filled with water flow. At this time, the fluff on the surface of the cloth is in a floating state. At this time, rolling up the cloth will flatten the fluff on the cloth along the rolling direction, avoiding the problem of fluff on the cloth after dehydration. Then, as the amount of rolled cloth increases, its own weight will also increase, thereby pressing the tray 8 downward. When the tray 8 slides downward to the bottom position, it will trigger the limit component to limit the sliding ring 15. When the limit component works, it will trigger the drainage component to drain the water flow in the cloth rolling area, and at the same time release the limiting effect of the docking mechanism on the roller frame for rolling up the cloth. For example, in one embodiment, the present invention further provides a cotton spunlace nonwoven fabric production process, which is applied to the above-mentioned cotton spunlace nonwoven fabric wastewater treatment equipment, comprising the following steps: Step S1: Place the roller frame for rolling up the fabric on the tray 8 and fix it by the docking mechanism. Then, as the amount of rolled up fabric increases, its own weight will increase accordingly, thereby pressing the tray 8 downward. When the tray 8 slides downward to the bottom position, the limit assembly will be triggered to limit the sliding ring 15, and the drainage assembly will be triggered to drain the water flow in the rolled fabric area. Step S2: When the limiting assembly is working, the annular ring 35 will be pressed downwards during the downward sliding process of the sliding ring 15. When the annular ring 35 slides downwards, the guide channel 38 and the guide block 36 are engaged with each other, thereby driving the annular sleeve 37 to rotate, so as to drive the connecting ring 30 to rotate. When the connecting ring 30 rotates, the slider 31 can slide toward one end of the block 34, and one side of the block 34 can be pushed out toward the inside of the fixed sleeve 4, so as to press and limit the sliding ring 15. Step S3: When the drainage assembly is working, when one side of the clamping block 34 is pushed out toward the inside of the fixing sleeve 4, one end of the clamping block 34 will fit with one side of the contact block 27, thereby pressing the contact block 27 toward the inside of the receiving groove 24, thereby driving the connecting rod 23 and the paddle plate 20 to slide toward one side. When the paddle plate 20 slides toward one side, the bottom of the through hole 18 will be opened to allow water to pass through. Step S4: When the docking mechanism is working, when the paddle plate 20 slides to one side, since one end of the paddle plate 20 fits against the bottom of the spring clamp 14, the bottom line of the spring clamp 14 will be pushed to one side, and then the top of the spring clamp 14 will be opened in the opposite direction, thereby releasing the constraint on the inner side of the drum frame for winding the fabric.

9. The wastewater treatment equipment for 100% cotton spunlace nonwoven fabric according to claim 8, characterized in that: The tray (8) has a notch (13) at the top, the sliding ring (15) has an annular opening (41) at the top, the annular opening (41) is communicated with one end of the guide groove (19), the bottom of the notch (13) penetrates into the annular opening (41), a spring clamp (14) is rotatably connected between the inner walls on both sides of the notch (13), the bottom of the spring clamp (14) extends into the annular opening (41) and fits with one end of the shift plate (20), the top hook end of the spring clamp (14) extends above the tray (8).

10. A cotton spunlace nonwoven production process, which is applied to a cotton spunlace nonwoven wastewater treatment device as described in any one of claims 1 to 9, characterized in that: The following steps are involved: Step S1: placing a roller frame for rolling up the fabric on a tray (8) and locking it in place via a docking mechanism; then, as the amount of rolled up fabric increases, its own weight also increases, thereby pressing the tray (8) downward; when the tray (8) slides downward to the bottom position, it triggers a limit assembly to limit the sliding ring (15), and simultaneously triggers a drainage assembly to drain water from the area where the fabric is rolled up; Step S2: When the limiting assembly is working, the annular ring (35) is pressed downwards during the downward sliding process of the sliding ring (15). When the annular ring (35) slides downwards, the guide path (38) and the guide block (36) are engaged with each other, thereby driving the annular sleeve (37) to rotate, thereby driving the connecting ring (30) to rotate. When the connecting ring (30) rotates, the slider (31) can slide toward one end of the clamping block (34), and one side of the clamping block (34) can be pushed out toward the inside of the fixed sleeve (4), thereby pressing and limiting the sliding ring (15); Step S3: When the drainage assembly is working, when one side of the clamping block (34) is pushed out toward the inside of the fixing sleeve (4), one end of the clamping block (34) will fit with one side of the contact block (27), thereby pressing the contact block (27) toward the inside of the receiving groove (24), thereby driving the connecting rod (23) and the paddle plate (20) to slide toward one side, and during the sliding process of the paddle plate (20) toward one side, the bottom of the through hole (18) will be opened, allowing water to flow through; Step S4: When the docking mechanism is working, when the paddle (20) slides to one side, since one end of the paddle (20) is in contact with the bottom of the spring clamp (14), the bottom line of the spring clamp (14) is pushed to one side, thereby causing the top of the spring clamp (14) to open in the opposite direction, thereby releasing the constraint on the inner side of the drum frame for winding the fabric.
