Description

Technical Field

[0001] The present invention relates to the technical field of drying devices, and in particular to a hydroentangled nonwoven fabric drying device and a processing method thereof. Background Art

[0002] Hydroentangled nonwoven fabric is a non-woven material in which fibers are entangled and reinforced by high-pressure water jets. It has high water absorbency, softness and environmental friendliness, and is widely used in medical, sanitary, industrial and other fields. During its production process, after the hydroentangling process, drying treatment is required to remove residual moisture. However, the existing drying technologies have the following key problems: 1. The water content of the hydroentangled nonwoven fabric is high. Traditional drying equipment mostly uses single hot air or heating plates for treatment, and it is difficult to quickly remove the internal moisture. For example, direct high-temperature drying easily causes the surface of the fibers to dry quickly while the internal moisture remains, resulting in uneven drying, and even causing the fabric to deform or shrink. In addition, some equipment lacks a pre-dehydration design, and the high-water-content fabric directly enters the drying link, further prolonging the processing time and increasing energy consumption.

[0003] 2. During the drying process, when the hydroentangled nonwoven fabric is transported on the conveying rollers in a wet state, its surface is prone to adhering to the residual impurity debris or water stain impurities on the conveying rollers. The traditional solutions lack an effective synchronous cleaning mechanism and cannot remove impurities in real time during the drying stage, resulting in a rough surface and uneven color of the finished product.

[0004] Therefore, we provide a hydroentangled nonwoven fabric drying device and a processing method thereof to solve the above-mentioned problems. Summary of the Invention

A first auxiliary shaft 16 is rotatably arranged on the chassis 1, and a second auxiliary shaft 20 is rotatably installed on the frame 2. A third toothed belt pulley 15 is fixed on the second auxiliary shaft 20. The first auxiliary shaft 16 and the second auxiliary shaft 20 are cooperated through an intermittent mechanism. When the first auxiliary shaft 16 rotates, it will drive the second auxiliary shaft 20 to rotate intermittently to drive the third toothed belt pulley 15 to rotate intermittently, so as to drive the conveying roller 12 to rotate intermittently to convey the non-woven fabric intermittently; Two clamping plates 53 for squeezing the non-woven fabric and located at the gap between two adjacent conveying rollers 12 are arranged on the frame 2. The first auxiliary shaft 16 and the clamping plates 53 are cooperated through a first linkage structure. When the first auxiliary shaft 16 rotates, it will drive the two clamping plates 53 to move relatively to squeeze the non-woven fabric to remove the moisture inside the non-woven fabric; A plurality of beating plates 39 for beating the non-woven fabric and located at the gap between two adjacent conveying rollers 12 are arranged on the frame 2. The first auxiliary shaft 16 and the beating plates 39 are cooperated through a second linkage structure. When the first auxiliary shaft 16 rotates, it will drive the beating plates 39 to move up and down reciprocally to beat the bottom of the non-woven fabric to keep the non-woven fabric fluffy during drying.

[0032] In this embodiment, when the first auxiliary shaft 16 rotates, it will drive the second auxiliary shaft 20 to rotate intermittently to drive the third toothed belt pulley 15 to rotate intermittently. The third toothed belt pulley 15 rotates intermittently. By using the toothed belt 57 to drive the first toothed belt pulley 13 and the second toothed belt pulley 14 to rotate intermittently between the first toothed belt pulley 13, the second toothed belt pulley 14 and the third toothed belt pulley 15, multiple conveying rollers 12 are driven to rotate intermittently to convey the non-woven fabric intermittently. By setting multiple intermittently rotating conveying rollers 12 to convey the non-woven fabric intermittently, when the spunlace non-woven fabric is intermittently conveyed on the conveying rollers 12, it will repeat the action of moving forward a certain distance and then stopping. When the spunlace non-woven fabric stops, by setting two clamping plates 53 in front of the drying mechanism, when the first auxiliary shaft 16 rotates, it will drive the two clamping plates 53 to move relatively.

By using the reciprocating movement of the beating plates 39 to beat the bottom of the non-woven fabric to keep the non-woven fabric fluffy during drying all the time. Beating is beneficial to the full contact between the hot air and the internal fibers of the non-woven fabric to accelerate the drying speed, and at the same time avoid the fabric deformation or shrinkage caused by uneven drying. In addition, beating can shake off the residual impurities, debris or water stain impurities adhered to the bottom surface of the non-woven fabric on the conveying roller, and remove the impurities on the surface in real time during the drying stage.

[0034] In this embodiment, the electric heating plate 11 of the motor 7 is electrically connected to the external power supply through a wire. The starting motor 7 drives the main shaft 8 to rotate, driving the impeller 9 inside the fan housing 4 to rotate and blow air into the exhaust pipe 6. The air inlet 5 is used to enter the fan housing 4. The air in the inner cavity of the heating chamber 10 can be heated by the electric heating plate 11, and the air entering the exhaust pipe 6 can blow the hot air to the surface of the non-woven fabric transported by the conveying roller 12, thereby removing moisture from the surface of the non-woven fabric and drying it.

When the connecting plate 24 rotates clockwise, it will drive the helical teeth 27 to rotate clockwise, so that the helical teeth 27 are clamped on the ratchet gear 21 to drive the ratchet gear 21 to rotate to drive the second secondary shaft 20 to rotate. When the second secondary shaft 20 rotates, it will drive the third toothed pulley 15 to rotate. In addition, when the connecting plate 24 rotates counterclockwise, it will drive the helical teeth 27 to rotate counterclockwise. The helical teeth 27 are meshed and clamped on the ratchet gear 21.

[0049] The working principle of the invention is as follows: The spunlace non-woven fabric to be dried is laid flat on the surface of the conveying roller 12 and intermittently conveyed by the conveying roller 12; when the spunlace non-woven fabric is intermittently conveyed on the conveying roller 12, it will repeat the action of moving forward a certain distance and then staying still. When the spunlace non-woven fabric stays still, the two clamping plates 53 move relatively to squeeze the non-woven fabric to remove the moisture inside the non-woven fabric before drying; the spunlace non-woven fabric after removing the internal moisture continues to be conveyed forward to the bottom of the drying mechanism, and the surface of the non-woven fabric is dried by hot air blowing through the drying mechanism; during the drying process of the spunlace non-woven fabric and when staying still during the intermittent forward conveying process, the beating plate 39 reciprocates up and down to beat the bottom of the non-woven fabric to keep the non-woven fabric fluffy during drying, so as to cooperate with the intermittent forward conveying of the non-woven fabric to realize the continuous drying operation of the non-woven fabric.

[0050] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
