[0025] As shown in Figures 1 to 17 An embodiment of the present application provides a fabric dewatering device, which comprises a dewatering box 110, a first driving mechanism and a second driving mechanism. A dewatering cylinder is rotatably arranged in the dewatering box 110, and a dewatering cavity is formed between the dewatering cylinder and the dewatering box 110. The dewatering cylinder comprises a rotating bottom plate 130 and a plurality of dewatering plates 160. The axis of the rotating bottom plate 130 extends in the up-down direction. The plurality of dewatering plates 160 are circularly distributed on the rotating bottom plate 130, and each dewatering plate 160 can slide in the radial direction of the rotating bottom plate 130. Each dewatering plate 160 has two dewatering surfaces which are spaced apart in the radial direction of the rotating bottom plate 130, and the two dewatering surfaces respectively face the inner side and the outer side of the dewatering cylinder. Each dewatering plate 160 is provided with a dewatering hole which penetrates the two dewatering surfaces. The dewatering hole enables the water flow generated by centrifugation of the fabric to enter the dewatering cavity.

[0026] The first driving mechanism can drive the rotating bottom plate 130 to rotate around the vertical axis, thereby driving the plurality of dewatering plates 160 to revolve around the vertical axis. The second driving mechanism can drive each dewatering plate 160 to slide a set distance in the radial direction of the rotating bottom plate 130, and drive each dewatering plate 160 to rotate 180° around the vertical axis, so as to switch the positions of the two dewatering surfaces.

[0027] When the clogging occurs on one of the dewatering surfaces on the dewatering plate 160, the positions of the two dewatering surfaces are switched by the second driving mechanism, and the water flow generated by centrifugation on the fabric is used to backflush the clogged dewatering surface, so that manual cleaning after disassembly is not required, and the cleaning efficiency can be improved.

[0028] Further, the dewatering surface is an arc surface, and the axis of the arc surface extends in the up-down direction.

The dewatering holes are arranged on the first arc protrusions and the second arc protrusions.

[0030] Further, the rotating base plate 130 is provided with a plurality of sliding grooves extending in the radial direction thereof, the second driving mechanism comprises a second motor 114, a gear transmission mechanism, a horizontal lead screw 137 and a horizontal sliding block 149; the horizontal lead screw 137 corresponds to the sliding grooves one by one and is rotationally arranged in the sliding grooves, the horizontal lead screw 137 extends along the length direction of the sliding grooves, the horizontal sliding block 149 is threadedly connected to the horizontal lead screw 137, the horizontal sliding block 149 is connected to the dewatering plate 160, and the output end of the second motor 114 drives the horizontal lead screw 137 to rotate around the axis thereof through the gear transmission mechanism, so as to drive the horizontal sliding block 149 to slide along the sliding grooves, and further drive the horizontal sliding block 149 to slide the dewatering plate 160 along the radial direction of the rotating base plate 130 by a set distance.

[0031] The rotating base plate 130 can be circular, or can be provided with a circular plate in the middle, and a plurality of track plates extending in the radial direction thereof are arranged on the circular plate, and the sliding grooves are arranged on the track plates.

[0032] As Figure 8As shown, the gear mechanism includes a driving wheel 146, a bevel gear ring 147 and a plurality of bevel gears 148.

[0034] The rolling mode of the flexible transmission belt 134 along the limiting rod 135 is the same as the moving mode of the track in the prior art. In this way, the rotation of the dehydration plates 160 can be automatically realized after the horizontal sliding block 149 drives the dehydration plates 160 to slide for a set distance.

[0035] When it is needed to reset the dehydration plates 160, the second motor 114 is reversed, at this time, the horizontal sliding block 149 drives the flexible transmission belt 134 and the limiting rod 135 to move synchronously towards the axis of the rotating bottom plate 130 again through the first gear 133 and the second gear 136, until the plurality of dehydration plates 160 re-enclose the dehydration cylinder.

Then the first motor 113 is started to drive the rotating bottom plate 130 to rotate around the vertical axis, so that the rotating bottom plate 130 drives the dehydration cylinder composed of the plurality of dehydration plates 160 to rotate, realizing centrifugal dehydration of the fabric. The water flow on the fabric flows through the dehydration holes into the dehydration cavity and is discharged outward.

[0051] Since the two guide plates 155 inside the dehydration plate 160 are distributed in a mule's foot shape, the water flow can be gathered, so that the recoil degree of the dehydration surface towards the outside of the dehydration cylinder is larger, and thus the cleaning effect of the dehydration equipment is better. Then the third motor 140 is started to drive the plurality of friction wheels 131 to rotate synchronously through the friction transmission mechanism, so that the plurality of vertical lead screws 132 are driven to rotate synchronously, the vertical sliding block 153 can move up and down on the vertical lead screw 132, and thus the two guide plates 155 are driven to move up and down synchronously, so that different positions of the dehydration surface towards the outside of the dehydration cylinder can be recoiled.

[0052] After the fabric is dehydrated and taken out, the second motor 114 is started to drive the horizontal lead screw 137 to rotate around its axis through the gear transmission mechanism, so that the horizontal sliding block 149 slides along the sliding groove. The movement of the horizontal sliding block 149 can drive the flexible transmission belt 134 and the limiting rod 135 to move synchronously through the first gear 133 and the second gear 136. When the limiting rod 135 moves to the position of contacting the side wall of the sliding groove and stops moving, the continuous movement of the horizontal sliding block 149 can drive the flexible transmission belt 134 to roll along the limiting rod 135, so that the first gear 133 rotates inside the flexible transmission belt 134, and thus the second gear 136 drives the dehydration plate 160 to rotate 180° around the vertical axis, thereby realizing switching of the dehydration surface. Then the second motor 114 is reversed to drive the horizontal lead screw 137 to rotate reversely and drive the horizontal sliding block 149 to slide reversely, so that the dehydration plate 160 can be reset and form the dehydration cylinder again.

[0053] During the rotation of 180° of the dehydration plate 160, the two vertical plates 154 on the dehydration plate 160 can move close to each other in the horizontal direction under the guidance of the limiting groove, so that the two rotating shafts 157 are driven to rotate synchronously, and the two guide plates 155 are driven to rotate to the initial angle again. That is, after the positions of the two dehydration surfaces are switched, the two guide plates 155 always distribute in a mule's foot shape, and the large end opening of the mule's foot shape faces the axis of the rotating bottom plate 130, so that the recoil effect is continuously ensured.

[0054] The above steps are repeated, so that the dehydration cylinder can be cleaned.

[0055] Any combination of the technical features in the above embodiments can be made, and for the sake of brevity, not all possible combinations are described above, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered within the scope of the present disclosure.

It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
