Description

Technical Field

[0001] The invention relates to the technical field of cloth squeezing water, in particular to a water squeezing device for printing and dyeing cloth and a water squeezing method thereof. Background Art

[0002] After printing and dyeing, the fabric needs to be dehydrated and dried to facilitate coloring.

[0003] Currently, water squeezing equipment for fabrics usually uses two counter-rotating squeezing wheels to directly squeeze the fabric and use pressure to dehydrate the fabric. Due to the high pressure between the squeezing wheels, the fabric will be stretched during the rotation process, resulting in poor durability of the fabric and affecting the performance of the fabric.

[0004] An invention patent with authorization announcement number CN113587611B is now disclosed, which is a fabric dehydration device, disclosing vertical plates, two groups of rotating rollers are symmetrically arranged between the vertical plates, a squeezing mechanism is sleeved on the rotating roller, a dehydration mechanism composed of absorbent cloth and protrusions is sleeved on the outer side of the squeezing mechanism, and also includes a second hot air blower blowing toward the dehydration mechanism; wherein, the absorbent cloth is used to transfer the moisture on the cloth, and then the squeezing mechanism and the block are used to cooperate to repeatedly squeeze and relax the absorbent cloth to improve the water absorption effect of the absorbent cloth, and when the absorbent cloth rotates to the position of the second hot air blower, the second hot air blower is used to dry the absorbent cloth to evaporate the moisture in the cloth.

[0005] During this process, the absorbent cloth rotates while contacting the absorbent cloth. At this time, the absorbent cloth and the cloth are in contact to achieve the transfer of water. When the squeezing mechanism expands the absorbent cloth, although the fiber spacing inside the absorbent cloth increases, the water diffuses, and the absorbent cloth and the cloth remain in contact at this time. When the absorbent cloth is squeezed again, the internal fiber spacing decreases, and the water is easy to flow back into the cloth, which will affect the water absorption effect of the absorbent cloth. Although the improvement of this solution reduces the risk of damage to the cloth, it results in unsatisfactory dehydration effect of the cloth.

[0006] Therefore, how to design a water squeezing device to improve the dehydration effect of cloth has become a technical problem that needs to be solved urgently by people in this field. Summary of the invention

[0007] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a water squeezing device for printing and dyeing fabrics, which can solve the risk of damage to the fabric due to squeezing, improve the dehydration effect of the fabric, and prevent the moisture in the absorbent fabric from flowing back into the fabric.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] A water squeezing device for printing and dyeing fabrics, comprising vertically arranged plates symmetrically disposed, between which there are two sets of rotatably connected rotating rollers. A transmission belt is sleeved outside the rotating rollers, and a number of telescopic mechanisms are fixedly arranged on the surface of the transmission belt. A connecting block is fixedly arranged at the end of the telescopic mechanism. An absorbent cloth is sleeved outside the connecting block outside the transmission belt. A number of blocks with a trapezoidal cross-section are arranged on the side wall of the vertical plate. A support tube slidably connected to the block is arranged on the side wall of the connecting block. Below the absorbent cloth, there is a fabric supporting component slidably connected along the vertical direction of the vertical plate and a pushing mechanism for driving the movement of the fabric supporting component. The connecting block is of a hollow structure. A partition is arranged in the inner cavity of the connecting block. The two sides of the partition are respectively a water storage cavity and a water squeezing cavity. The water squeezing cavity is close to the transmission belt side. A support sleeve for communicating the water squeezing cavity with the outside is arranged in the connecting block. A number of water guiding holes for communicating the water squeezing cavity with the water storage cavity are arranged on the partition. Absorbent sponges are arranged in the water squeezing cavity, absorbent cotton strips are arranged in the support sleeves, and an extrusion device fixedly connected to the transmission belt is arranged in the water squeezing cavity. A blocking mechanism for opening or closing the water guiding holes is also arranged on the extrusion device. When the support tube contacts the block, the absorbent sponge is in an extrusion state and the water guiding holes are opened.

[0010] Further, the extrusion device includes an extrusion plate and a positioning rod. The extrusion plate is located in the water squeezing cavity and abuts against the absorbent sponge. One end of the positioning rod is fixed on the transmission belt, and the other end of the positioning rod extends into the water squeezing cavity and is fixedly connected to the extrusion plate. The positioning rod is slidably connected to the connecting block.

[0011] Further, the blocking mechanism includes a push rod and a closing plate. One end of the push rod is fixed on the extrusion plate, and the other end of the push rod passes through the water guiding hole and extends into the water storage cavity. The closing plate is fixedly installed on the push rod to block the water guiding hole.

[0012] Further, a closed annular groove coaxial with the water guiding hole is arranged on the inner wall of the water storage cavity. An inserted convex ring is fixedly arranged on the closing plate. When the water guiding hole is closed, the inserted convex ring is inserted into the closed annular groove.

[0013] Further, a pushing plate fixed on the vertical plate is arranged between the two rotating rollers. The pushing plate is horizontally arranged, and the bottom wall of the pushing plate abuts against the transmission belt at the bottom of the pushing plate.

[0014] Further, the side wall of the water storage cavity close to the transmission belt forms an angle α with the horizontal plane. One of the two support tubes is communicated with the water storage cavity. When the connecting block is directly above the pushing plate, the support tube communicated with the water storage cavity is at the lowest position of the water storage cavity.

[0015] Further, the telescopic mechanism includes a positioning sleeve, a telescopic rod and a spring. The positioning sleeve is fixedly installed on the outer wall of the transmission belt. One end of the telescopic rod is slidably connected to the inner cavity of the positioning sleeve, and the other end of the telescopic rod is fixedly connected to the connecting block. The spring is installed in the inner cavity of the positioning sleeve. One end of the spring abuts against the inner wall of the positioning sleeve, and the other end of the spring abuts against the telescopic rod.

[0016] Further, the fabric supporting assembly includes two symmetrically arranged frames, and a plurality of rotatably connected supporting rollers are arranged between the two frames. The plurality of supporting rollers are arranged in sequence along the advancing direction of the fabric. A pushing chute is arranged on the side wall of the vertical plate along the height direction of the vertical plate. A sliding block inserted into the pushing chute is fixedly arranged on the frame, and the side wall of the sliding block is slidably connected with the inner wall of the pushing chute.

[0017] Further, the stopper is successively provided with a first pushing inclined surface, a second pushing surface and a third pushing inclined surface. The first pushing inclined surface and the third pushing inclined surface are inclined, and the second pushing surface is located between the first pushing inclined surface and the third pushing inclined surface and is horizontally arranged. A plurality of stoppers are arranged in sequence along the advancing direction of the fabric.

[0018] A method for squeezing water from printed and dyed fabric further includes a conveying roller for conveying the fabric;

[0019] The first step: The pushing mechanism pushes the fabric supporting assembly to move downward to increase the gap between the fabric supporting assembly and the water-absorbing cloth.

[0020] The second step: Pass the fabric through the gap between the water-absorbing cloth and the fabric supporting assembly and bypass the peripheral wall of the conveying roller.

[0021] The third step: Use the pushing mechanism to drive the fabric supporting assembly to move upward so that the fabric abuts against the bottom wall of the water-absorbing cloth.

[0022] The fourth step: Drive the conveying roller and the rotating roller to rotate synchronously. The conveying roller drives the water-absorbing cloth to be attached to the fabric and move forward synchronously through the transmission belt, the telescopic mechanism and the connecting block.

[0023] On the basis of the fourth step, as the connecting block moves, the support pipe of the connecting block located below the pushing plate contacts the first pushing inclined surface of the stopper, and the connecting block moves toward the side close to the transmission belt, squeezing the water-absorbing sponge by the squeezing device, and the blocking mechanism opens the water guiding hole, and the water is stored in the water storage cavity through the water guiding hole.

[0024] The support pipe contacts the third pushing inclined surface of the stopper, the connecting block moves toward the side away from the transmission belt, the blocking mechanism closes the water guiding hole, the water-absorbing sponge expands, and the water-absorbing cloth is subjected to water absorption treatment through the water-absorbing cotton strip.

[0025] After the connecting block moves to directly above the pushing plate, the blocking mechanism closes the water guiding hole, and the water in the water storage cavity flows out through the support pipe.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The fabric passes through between the water-absorbing cloth and the fabric supporting component, and the gap between the fabric supporting component and the water-absorbing cloth is adjusted by the pushing mechanism to make the water-absorbing cloth contact the fabric, thereby performing water absorption treatment on the fabric; by the contact between the support tube and several stoppers, the connecting block reciprocally switches between contact and detachment from the water-absorbing cloth, thereby enabling the water-absorbing cloth to switch between the squeezing and relaxing states;

[0027] When the connecting block disengages from contact with the water-absorbing cloth, at this time, the connecting block compresses the telescopic mechanism and moves towards the conveyor belt side, the water-absorbing cloth relaxes, improving the water absorption effect of the water-absorbing cloth on the fabric. Since the squeezing device is fixedly installed on the conveyor belt, relative movement between the water-absorbing sponge and the squeezing device is caused, thereby squeezing the water-absorbing sponge. At this time, the water guiding holes are opened, and water enters the water storage cavity for storage. When the connecting block contacts the water-absorbing cloth again, the water guiding holes are blocked by the blocking mechanism, and the water-absorbing sponge expands, and the water in the water-absorbing cloth is re-absorbed through the water-absorbing cotton strip, avoiding the outward flow of water when the water-absorbing cloth is squeezed again, which affects the water absorption effect of the fabric;

[0028] When the connecting block moves above the rotating roller, the support tube disengages from contact with the stopper, and the blocking mechanism blocks the water guiding holes to prevent the water in the water storage cavity from flowing back into the water squeezing cavity.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] This embodiment provides a water squeezing device for printing and dyeing fabrics, mainly reducing the damage to the fabrics caused by the dragging of the squeezing roller during the water squeezing process of the fabrics, transferring the water on the absorbent cloth, and improving the water absorption effect of the fabrics.

[0042] As Figure 1 、 Figure 2 and Figure 3 shown, it includes two vertically arranged plates 1 that are symmetric front and back. Among them, an absorbent component for dehydrating the fabric is installed between the two vertically arranged plates 1, and a fabric supporting component 2 that is slidably connected along the height direction of the vertically arranged plates 1 is arranged below the absorbent component. Specifically, there is a gap for the fabric 100 to pass through between the absorbent component and the fabric supporting component 2.

[0043] Among them, when the fabric 100 is dehydrated, as Figure 1 and Figure 3 shown, the fabric 100 passes through the gap between the absorbent component and the fabric supporting component 2 from the left side of the vertically arranged plate 1, and then passes out from the right side of the vertically arranged plate 1. The fabric 100 moves along the Figure 3 arrow direction in the figure.

[0044] Specifically, in order to realize the movement of the fabric 100, in this embodiment, asFigure 1 As shown, a conveying roller 19 is provided on the right side of the vertical plate 1. Among them, the fabric 100 bypasses the outside of the conveying roller 19, and the rotation of the conveying roller 19 drives the fabric 100 to move accordingly.

[0045] Among them, in order to support the fabric 100, as Figure 2 shown, the fabric support assembly 2 includes two sets of front and rear symmetric frames 21. Among them, several support rollers 22 arranged in sequence are rotatably provided between the two frames 21. Among them, as Figure 3 shown, several support rollers 22 are arranged in sequence from left to right, and the horizontal plane where the highest point of the peripheral wall of the support roller 22 is located is higher than the top wall of the frame 21.

[0046] Through the above settings, when the fabric 100 passes through the gap between the water absorption component and the fabric support assembly 2, at this time, the fabric 100 will be supported by the support rollers 22 to prevent the fabric 100 from falling downward.

[0047] In order to facilitate the dehydration treatment of fabrics 100 with different thicknesses and facilitate the installation of the fabric 100, in this embodiment, as Figure 1 and Figure 2 shown, a number of pushing chutes 11 are provided on the vertical plate 1 along the height direction of the vertical plate 1. A slider 23 inserted into the pushing chute 11 is fixedly provided on the frame 21. Among them, the side wall of the slider 23 is slidably connected to the side wall of the pushing chute 11. A pushing mechanism 17 is also fixedly installed in the pushing chute 11. Among them, the housing of the pushing mechanism 17 is fixedly connected to the vertical plate 1, and the pushing end of the pushing mechanism 17 is fixedly connected to the slider 23.

[0048] Through the above settings, before installing the fabric 100, the frame 21 is pushed downward by the pushing mechanism 17 to increase the gap between the support roller 22 and the water absorption component; then the fabric 100 is passed through the gap between the support roller 22 and the water absorption component, and then the fabric 100 is bypassed around the conveying roller 19. Finally, the pushing mechanism 17 lifts the frame 21 so that the fabric 100 abuts against the water absorption component to complete the installation of the fabric 100.

[0049] Specifically, in this embodiment, the pushing mechanism 17 can be selected from an electric push rod or a pushing cylinder.

[0050] In order to enable the fabric 100 to pass through the fabric support assembly 2 smoothly, in this embodiment, as Figure 3 、 Figure 4 and Figure 5As shown, two groups of rotating rollers 30 located on the same horizontal plane are rotatably provided on the vertical plate 1. A pulley set 14 is installed between the two rotating rollers 30. It further includes a motor 15. Among them, the output shaft of the motor 15 is fixedly connected to one of the rotating rollers 30. A transmission belt 31 is sleeved on the outer sides of the two rotating rollers 30. The water absorption component is installed on the outer side of the transmission belt 31.

[0051] Through the above settings, the motor 15 drives, and then drives the two rotating rollers 30 to rotate synchronously through the pulley set 14, and drives the water absorption component to move through the transmission belt 31. Here, it is worth noting that the moving speed of the water absorption component is the same as the moving speed of the fabric 100, so that the water absorption component continuously absorbs water from the fabric 100.

[0052] In order to install the motor 15, in this embodiment, as Figure 4 shown, a mounting frame 13 is fixedly connected to the side wall of the vertical plate 1 by bolts. Among them, the motor 15 is fixedly installed on the mounting frame 13.

[0053] When the water absorption component and the fabric 100 move synchronously on the supporting roller 22, since the fabric 100 is located between the water absorption component and the supporting roller 22, as the fabric moves, a part of the water on the fabric 100 will fall downward. Therefore, in this embodiment, as Figure 2 and Figure 3 shown, a water receiving funnel 18 located below the supporting roller 22 is fixedly provided at the bottom of the frame 21. The water receiving funnel 18 is used to receive the water falling from the fabric 100 and guide the water discharged from the fabric 100 to prevent the water from flowing wantonly.

[0054] In order to absorb water from the fabric 100, in this embodiment, as Figure 3 and Figure 5 shown, the water absorption component includes a telescopic mechanism 33, a connecting block 4, and a water absorption cloth 5. Among them, several groups of telescopic mechanisms 33 are provided and fixedly installed on the outer surface of the transmission belt 31. The connecting block 4 is fixedly installed at the telescopic end of the telescopic mechanism 33. The water absorption cloth 5 is in a ring shape with the head and tail connected and is sleeved on the outer side of the transmission belt 31. Among them, the outer wall of the connecting block 4 abuts against the inner wall of the water absorption cloth 5, and the water absorption cloth 5 is directly in contact with the fabric 100.

[0055] Specifically, in this embodiment, as Figure 5As shown, the telescopic mechanism 33 includes a positioning sleeve 331, a telescopic rod 332, and a spring 333. Among them, the positioning sleeve 331 is fixedly installed on the conveyor belt 31. The spring 333 is installed in the inner cavity of the positioning sleeve 331. The telescopic rod 332 is slidably connected to the side wall of the inner cavity of the positioning sleeve 331. One end of the spring 333 abuts against the inner wall of the positioning sleeve 331, and the other end of the spring 333 abuts against the telescopic rod 332. The other end of the telescopic rod 332 is fixedly connected to the connecting block 4. When the water-absorbing cloth 5 is sleeved outside the connecting block 4, the water-absorbing cloth 5 is in a squeezed state.

[0056] In order to enable the water-absorbing cloth 5 to better absorb the moisture in the cloth 100, in this embodiment, when necessary, the water-absorbing cloth 5 reciprocally switches between the squeezed state and the relaxed state. After the water-absorbing cloth 5 relaxes, the fiber gaps between the water-absorbing cloths 5 increase, and thus the water on the cloth 100 can be absorbed.

[0057] Specifically, as Figure 2 , Figure 3 and Figure 5 shown, first support pipes 401 and second support pipes 402 are respectively and fixedly installed at both ends of the connecting block 4. A plurality of stoppers 16 arranged along the conveying direction of the cloth 100 are fixedly installed on the side wall of the vertical plate 1. Among them, as Figure 7 shown, a first pushing inclined surface 161, a second pushing surface 162, and a third pushing inclined surface 163 are successively arranged on the stopper 16 along the conveying direction of the cloth 100. Among them, the longitudinal section of the stopper 16 is in the shape of an isosceles trapezoid. The first pushing inclined surface 161 and the third pushing inclined surface 163 are respectively the hypotenuses on both sides, and the second pushing surface 162 is a horizontal plane and is located at the highest position.

[0058] Among them, as the connecting block 4 moves, the first support pipe 401 and the second support pipe 402 successively pass through the first pushing inclined surface 161, the second pushing surface 162, and the third pushing inclined surface 163 and reach the position of the first pushing inclined surface 161. At this time, the first support pipe 401 and the second support pipe 402 push the connecting block 4 to separate from the water-absorbing cloth 5, and thus the water-absorbing cloth 5 here begins to relax. When the first support pipe 401 and the second support pipe 402 move to the position of the second pushing surface 162, the connecting block 4 is completely separated from the water-absorbing cloth 5. At this time, the water-absorbing cloth 5 is in a continuous relaxed state and can absorb the water on the cloth 100. When the second support pipe 402 and the first support pipe 401 move to the position of the third pushing inclined surface 163, at this time, the connecting block 4 moves closer to the water-absorbing cloth 5 again and squeezes the water-absorbing cloth 5 again. It should be noted here that a plurality of stoppers 16 are arranged along the advancing direction of the cloth 100, and the squeezing and relaxation of the water-absorbing cloth 5 can be reciprocally realized, and thus the water absorption treatment of the cloth 100 can be better performed.

[0059] When the first support tube 401 and the second support tube 402 are transferred from the second pushing surface 162 to the third pushing inclined surface 163, the water-absorbing cloth 5 starts to be squeezed. At this time, the water in the water-absorbing cloth 5 is easily squeezed out and flows back to the cloth 100, resulting in poor dehydration effect of the cloth 100. To solve this problem, in this embodiment, as Figure 6 shown, the connecting block 4 is of a hollow structure, and a partition 41 that divides its inner cavity into a water storage cavity 42 and a water squeezing cavity 43 is provided in the inner cavity of the connecting block 4. Among them, a number of support sleeves 44 are provided in the water storage cavity 42. One end of the support sleeve 44 communicates with the outside, and the other end communicates with the water squeezing cavity 43. As Figure 8 shown, a water guiding hole 411 that communicates the water storage cavity 42 with the water squeezing cavity 43 is further provided on the partition 41. Among them, a water-absorbing sponge 7 is provided inside the water squeezing cavity 43, and a water-absorbing cotton strip 8 is filled in the support sleeve 44. One end of the water-absorbing cotton strip 8 is connected to the water-absorbing sponge 7, and the other end of the water-absorbing cotton strip 8 extends out of the connecting block 4. A squeezing device fixedly connected to the transmission belt 31 is further provided in the water squeezing cavity 43.

[0060] Through the above settings, combined with Figure 6 、 Figure 7 and Figure 8 to illustrate the dehydration of the cloth 100, Figure 6 is the position where the connecting block 4 rotates to below the rotating roller 30. At this time, the first support tube 401 and the second support tube 402 on the connecting block 4 do not contact the stopper 16. At this time, the water-absorbing cloth 5 is attached to the cloth 100, and the water-absorbing cloth 5 is in a squeezed state. At this time, the water-absorbing cotton strip 8 extending out of the connecting block 4 contacts the water-absorbing cloth 5, and the water-absorbing sponge 7 is in an un-squeezed state (relaxed state). At this time, the water-absorbing cloth 5 contacts the cloth 100, and the water-absorbing cloth 5 absorbs the water on the cloth 100 and transfers it to the water-absorbing cotton strip 8. Since the water-absorbing sponge 7 is in a relaxed state, the water on the cloth 100 is transferred to the water-absorbing sponge 7.

[0061] As the connecting block 4 and the water-absorbing cloth 5 rotate under the action of the rotating roller 30, at this time, the first support tube 401 and the second support tube 402 on the connecting block 4 gradually approach the first pushing inclined surface 161 of the stopper 16. As the first support tube 401 and the second support tube 402 climb, at this time, the connecting block 4 is lifted by the stopper 16, and the connecting block 4 moves away from the water-absorbing cloth 5. The water-absorbing cotton strip 8 is separated from the water-absorbing cloth 5. At this time, the water-absorbing cloth 5 changes from a squeezed state to a relaxed state, and the internal fiber spacing increases, and it starts to continue to absorb water from the cloth 100. As the connecting block 4 moves away from the water-absorbing cloth 5, at this time, the spring 333 in the telescopic mechanism 33 is squeezed. Since the squeezing device is fixed on the transmission belt 31, therefore, the squeezing device and the water-absorbing sponge 7 move relatively, as Figure 7As shown, at this time, the water-absorbing sponge 7 is squeezed, and the water in the water-absorbing sponge 7 enters the water storage cavity 42 through the water guide holes 411, thereby separating the water in the water-absorbing sponge 7. When the first support tube 401 and the second support tube 402 are located on the second pushing surface 162, the water-absorbing sponge 7 is in a continuously squeezed state at this time, thereby improving the effect of separating water from the water-absorbing sponge 7.

[0062] When the first support tube 401 and the second support tube 402 move to the position of the third pushing inclined surface 163, the connecting block 4 starts to move towards the water-absorbing cloth 5 at this time. The spring 333 in the telescopic mechanism 33 provides power for the movement of the connecting block 4. At this time, the squeezed state of the water-absorbing sponge 7 is gradually released. When the first support tube 401 and the second support tube 402 disengage from the stopper 16, the water-absorbing cotton strip 8 contacts the water-absorbing cloth 5 again at this time. Since the water-absorbing sponge 7 is in an emptied state at this time, therefore, the water in the water-absorbing cloth 5 will be re-absorbed by the water-absorbing sponge 7 through the water-absorbing cotton strip 8. As the first support tube 401 and the second support tube 402 pass through a number of stoppers 16 in sequence, the reciprocating movement of the connecting block 4 can be realized. At this time, the water-absorbing cloth 5 reciprocates alternately between the squeezed and relaxed states, and the water in the water-absorbing cloth 5 is transferred to the water storage cavity 42, solving the problem that the water flows back to the fabric 100 when the water-absorbing cloth 5 is in the squeezed state, and improving the dehydration effect of the fabric 100.

[0063] From Figure 4 and Figure 5 it can be seen that the rotation of the water-absorbing cloth 5 is driven by two rotating rollers 30. The transmission belt 31 is usually relatively soft. When the connecting block 4 is located below the position between the two rotating rollers 30, since the connecting block 4 needs to reciprocate up and down, the squeezing device fixedly installed on the transmission belt 31 needs to move relative to the connecting block 4 at this time. In order to ensure the relative movement, in this embodiment, a pushing plate 34 fixed to the vertical plate 1 is provided between the two rotating rollers 30. Among them, the lower part of the transmission belt 31 abuts against the bottom wall of the pushing plate 34 to prevent the lower area of the transmission belt 31 from deforming.

[0064] Specifically, in this embodiment, as Figure 6 shown, the squeezing device includes a positioning rod 32 and a squeezing plate 6. Among them, the squeezing plate 6 is located in the water squeezing cavity 43 and abuts against the water-absorbing sponge 7. One end of the positioning rod 32 is fixed on the transmission belt 31, and the other extends into the water squeezing cavity 43 and is fixedly connected to the squeezing plate 6.

[0065] With the above settings, when the connecting block 4 is pushed away from the water-absorbing cloth 5 under the action of the first support tube 401, the second support tube 402 and the stopper 16, the spring 333 in the telescopic mechanism 33 is compressed at this time. While the positioning rod 32 has an upward movement tendency, it abuts against the pushing plate 34, restricting the movement of the positioning rod 32 and the pressing plate 6. At this time, the water-absorbing sponge 7 and the partition plate 41 move upward relative to the pressing plate 6, thereby squeezing the water-absorbing sponge 7, and thus realizing the separation action of the water-absorbing sponge 7 from water.

[0066] It should be noted here that when the connecting block 4 is directly below the pushing plate 34, as Figure 6 and Figure 7 shown, taking this as an example, at this time the water storage cavity 42 is located below the water squeezing cavity 43. When the water in the water-absorbing sponge 7 is squeezed by the pressing plate 6, at this time, under the action of gravity, the water enters the water storage cavity 42 through the water guiding holes 411 for temporary storage of water.

[0067] On the basis of the above solution, as the water-absorbing cloth 5 and the connecting block 4 rotate, the connecting block 4 will rotate above the pushing plate 34. At this time, as Figure 9 shown, at this time the water storage cavity 42 will be transferred above the water squeezing cavity 43. During this process, if the water guiding holes 411 are not processed, then the water in the water storage cavity 42 will flow back along the water guiding holes 411 into the water squeezing cavity 43 and be re-absorbed by the water-absorbing sponge 7. When the connecting block 4 above the pushing plate 34 is transferred below the pushing plate 34 again, since the water-absorbing sponge 7 is in a saturated state, it will affect the water absorption effect on the fabric 100. Therefore, special plugging treatment needs to be carried out on the water guiding holes 411.

[0068] To solve the problem that the water in the water storage cavity 42 flows to the water squeezing cavity 43 along the water guiding holes 411, in this embodiment, as Figure 6 and Figure 8 shown, taking the solution where the connecting block 4 is below the pushing plate 34 as an example, a push rod 9 is fixedly arranged on the pressing plate 6 and extends downward through the water guiding holes 411 into the water storage cavity 42. A closing plate 10 is fixedly arranged on the push rod 9. A closing ring groove 412 concentric with the water guiding holes 411 is arranged on the partition plate 41. The closing ring groove 412 is located in the water storage cavity 42. Among them, a plugging convex ring 101 capable of being inserted into the closing ring groove 412 is fixedly arranged on the closing plate 10. When the first support tube 401 and the second support tube 402 do not contact the stopper 16, as Figure 6As shown, at this time, the absorbent tampon 8 is in contact with the absorbent cloth 5, the absorbent sponge 7 is in a relaxed state, the pressing plate 6 stops pressing the absorbent sponge 7, and the plugging convex ring 101 is plugged into the closed ring groove 412, thereby plugging the water guiding hole 411; when the first support tube 401 and the second support tube 402 contact the stopper 16, at this time, the pressing plate 6 presses the absorbent sponge 7, the partition plate 41 moves upward relative to the push rod 9 and opens the water guiding hole 411, and at this time, the water in the absorbent sponge 7 can flow smoothly into the water storage cavity 42; when the connecting block 4 moves above the top pushing plate 34, since the connecting block 4 is separated from the contact with the stopper 16, at this time, the plugging convex ring 101 is plugged into the closed ring groove 412 to plug the water guiding hole 411, preventing the water in the water storage cavity 42 from flowing back into the water squeezing cavity 43.

[0069] In order to be able to timely discharge the water in the water storage cavity 42 from the connecting block 4, in this embodiment, as Figure 2 , Figure 9 and Figure 10 shown, the second support tube 402 communicates with the water storage cavity 42. It is worth noting here that, taking the connecting block 4 being above the top pushing plate 34 as an example, the bottom wall of the water storage cavity 42 on the side close to the top pushing plate 34 is inclined, and an angle α is formed between this bottom wall and the horizontal plane. At this time, the second support tube 402 is located at the lowest position of the water storage cavity 42, so that the water in the water storage cavity 42 flows outwards along its bottom wall from the second support tube 402.

[0070] It is worth noting here that when the connecting block 4 is below the top pushing plate 34, at this time, the second support tube 402 is located at the position of the top wall of the water storage cavity 42, and at this time, the water in the water storage cavity 42 will not flow outwards from the second support tube 402.

[0071] Wherein, a drain hole 4021 is further provided on the second support tube 402 for accelerating the discharge of the water in the water storage cavity 42.

[0072] In order to prevent the water from directly dropping onto the fabric 100, in this embodiment, as Figure 1 and Figure 2 shown, an installation groove 12 penetrating the front and rear side walls of the vertical plate 1 is provided on the vertical plate 1, and a drain plate 121 extending below the second support tube 402 is inclinedly installed in the installation groove 12. It is worth noting here that the second support tube 402 in this paragraph refers to the second support tube 402 located directly above the top pushing plate 34. At this time, the water in the water storage cavity 42 flows outwards through the second support tube 402 onto the drain plate 121, and the water is led to the outside of the vertical plate 1, preventing the water from directly contacting the fabric 100 and improving the dehydration effect of the fabric 100.

[0073] It is worth noting here that the drain plate 121 forms an angle with the horizontal plane to prevent the water from flowing back to the position between the two vertical plates 1.

[0074] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
