The drive assembly includes a rotary motor 111 and a first gear 112; two connection frames 3 are each mounted with a rotary motor 111; the output shafts of the two rotating motors 111 are fixedly connected with one wringing roller 102 respectively; a first gear 112 is fixedly connected to the left part of each of the two wringing rollers 102.
The specific working steps are as follows:
when the nano zinc oxide spunlaced nonwoven fabric 100 enters two wringing plates 101, the wringing plates 101 squeeze the nano zinc oxide spunlaced nonwoven fabric 100 up and down, so that water on the outer layer of the nano zinc oxide spunlaced nonwoven fabric 100 is squeezed out firstly, when the water is squeezed out, water on the upper layer stays on the nano zinc oxide spunlaced nonwoven fabric 100 firstly, and then is pushed to two sides by water squeezed out later, and flows out from two sides, and the squeezing efficiency is greatly reduced due to accumulation of the water; the water squeezing plate 101 is provided with the water inlet groove 101a, squeezed water flows into the water inlet groove 101b along the water inlet groove 101a, meanwhile, the water can be guided to flow to the two sides due to the fact that the middle of the water inlet groove 101b is high and the two sides are low, the left side and the right side of the water inlet groove 101a are in splayed orientation, when water enters the water inlet groove 101b, the water can enter the water inlet groove 101b in a state of flowing to the two sides, so that water is discharged quickly, meanwhile, when water flows to the two sides, the water possibly flows back into the nano zinc oxide water-jet non-woven fabric 100 through the water inlet groove 101a, the splayed orientation of the water inlet groove 101a enables the water to flow to the two sides only, the second half section of the water inlet groove 101a is blocked, and then the water is pushed away by the newly-entered water, and the effect of backflow prevention can be achieved.
When the nano zinc oxide spunlaced nonwoven fabric 100 enters between two wringing rollers 102, the rotating motor 111 drives the wringing rollers 102 to rotate, the wringing rollers 102 squeeze the inner layer of the nano zinc oxide spunlaced nonwoven fabric 100 and squeeze water in the inner layer, so that layered extrusion of the nano zinc oxide spunlaced nonwoven fabric 100 is realized, and the wringing effect is enhanced; when extrusion is carried out, the extruded water stays on the nano zinc oxide spunlaced non-woven fabric 100 in front of the wringing roller 102, so that the water extrusion effect is reduced when the nano zinc oxide spunlaced non-woven fabric 100 absorbs water again, when the water inlet holes 102a of the upper wringing roller 102 rotate to the nano zinc oxide spunlaced non-woven fabric 100, the water in the inner layer of the nano zinc oxide spunlaced non-woven fabric 100 is extruded, the extruded water enters the water inlet holes 102a and is absorbed by the first water absorbing block 103, the problem that the extruded water stays is solved, the extruded water below flows out directly along the water inlet holes 102a of the lower wringing roller 102, and the water inlet holes 102a of the upper wringing roller 102 and the water inlet holes 102a of the lower wringing roller 102 are in a staggered state, because when the nano zinc oxide spunlaced non-woven fabric 100 is internally extruded, if the water inlet holes 102a above and the nano zinc oxide spunlaced non-woven fabric 100 are simultaneously contacted, the water inlet holes 102a and the nano zinc oxide spunlaced non-woven fabric 100 are not contacted at the same time, and the water inlet holes 102a can be fully extruded and the water inlet holes can be fully kept under the condition that the water inlet holes are not completely; the two wringing rollers 102 push the nano zinc oxide spunlaced nonwoven fabric 100 into the drying box 1 for drying.
When the water squeezing of the nano zinc oxide spunlaced nonwoven fabric 100 is completed, the push rod 104 pushes the first water squeezing block 105 to squeeze the first water absorbing block 103, and the other side of the first water absorbing block 103 is blocked by the second water squeezing block 102b, so that the first water absorbing block 103 is squeezed to squeeze the absorbed water, then the water is discharged through the water inlet holes 102a of the lower water squeezing roller 102, and then the push rod 104 pushes the first water squeezing block 105 to return to the original position.
