Description

Technical Field

[0001] The present invention relates to the technical field of drying devices, and specifically to a spunlace non-woven fabric drying device and its processing method. Background Art

[0002] Spunlace non-woven 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 spunlace process, drying treatment is required to remove residual moisture. However, the existing drying technologies have the following key problems:

[0003] 1. The water content of the spunlace non-woven fabric after the spunlace process 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 fabric with high water content directly enters the drying link, further prolonging the processing time and increasing energy consumption.

[0004] 2. During the drying process, when the spunlace non-woven fabric is being conveyed on the conveying rollers and is 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.

[0005] Therefore, we provide a spunlace non-woven fabric drying device and its processing method to solve the above-mentioned problems. Summary of the Invention

[0049] A first toothed belt wheel 13 is fixed to one end of the conveying roller 12, and two second toothed belt wheels 14 and a third toothed belt wheel 15 are rotatably arranged on the frame 2. The first toothed belt wheel 13, the second toothed belt wheel 14, and the third toothed belt wheel 15 are connected to each other through a toothed belt 57.

[0050] A first secondary shaft 16 is rotatably provided on the base frame 1, a second secondary shaft 20 is rotatably installed on the frame 2, and a third toothed belt pulley 15 is fixed on the second secondary shaft 20. The first secondary shaft 16 and the second secondary shaft 20 are matched by an intermittent mechanism. When the first secondary shaft 16 rotates, it will drive the second secondary 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 provided on the frame 2, and the first secondary shaft 16 and the clamping plates 53 are matched by a first linkage structure. When the first secondary shaft 16 rotates, it will drive the two clamping plates 53 to move relative to squeeze the non-woven fabric to remove moisture inside the non-woven fabric;

[0051] The frame 2 is provided with a plurality of beating plates 39 for beating the non-woven fabric and located in the gap between two adjacent conveying rollers 12. The first sub-shaft 16 and the beating plates 39 are coordinated through a second linkage structure. When the first sub-shaft 16 rotates, it will drive the beating plates 39 to move up and down to beat the bottom of the non-woven fabric so that the non-woven fabric can maintain its fluffiness when drying.

[0052] In this embodiment, the first secondary shaft 16 rotates while driving the second secondary shaft 20 to rotate intermittently to drive the third toothed belt wheel 15 to rotate intermittently. The third toothed belt wheel 15 rotates intermittently, and the first toothed belt wheel 13, the second toothed belt wheel 14, and the third toothed belt wheel 15 are connected through a toothed belt 57 to drive the first toothed belt wheel 13 and the second toothed belt wheel 14 to rotate intermittently to drive multiple conveying rollers 12 to rotate intermittently to convey the non-woven fabric intermittently. By setting multiple intermittently rotating conveying rollers 12, the non-woven fabric is intermittently conveyed. When the spunlace non-woven fabric is intermittently conveyed on the conveying roller 12, it will repeat the action of conveying forward for a distance and then stopping. When the spunlace non-woven fabric is stationary, two clamping plates 53 are set in front of the drying mechanism, and the first secondary shaft 1 6 will drive the two clamping plates 53 to move relative to each other while rotating, and the non-woven fabric will be squeezed by the relative movement of the two clamping plates 53 to remove the moisture inside the non-woven fabric before drying. During the drying process of the spunlace non-woven fabric, and when the non-woven fabric is kept stationary during the intermittent forward conveying, the first secondary shaft 16 will drive the flapping plate 39 to move up and down while rotating, and the flapping plate 39 is used to flap the bottom of the non-woven fabric to keep the non-woven fabric fluffiness during drying. The flapping is conducive to the full contact between the hot air and the internal fibers of the non-woven fabric to accelerate the drying speed, while avoiding the deformation or shrinkage of the fabric caused by uneven drying.

[0054] 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.

[0059] In this embodiment, when the first secondary shaft 16 rotates, it will drive the first rotating disk 22 to rotate. The rotation of the first rotating disk 22 will drive the first swing arm 23 to swing to drive the connecting plate 24 to swing back and forth. 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.

When the fifth countershaft 40 rotates, it will drive the third turntable 47 to reciprocate and swing. The reciprocating swing of the third turntable 47 will drive the driving gear 48 on the sixth countershaft 43 to rotate, so as to drive the first driven gear 49 and the second driven gear 50 to rotate, thereby driving the two clamping jaws 51 to rotate relatively.

[0071] As a further solution of the present invention, the gear mechanism includes a first spur gear 29 fixed on the first countershaft 16 and a second spur gear 30 fixed on the third countershaft 28, and the first spur gear 29 meshes with the second spur gear 30;

[0072] The second bevel gear structure includes a first bevel gear 33 fixed on the third countershaft 28 and a first bevel gear ring 32 fixed on the fourth countershaft 31, and the first bevel gear ring 32 meshes with the first bevel gear 33.

[0073] In this embodiment, when the first countershaft 16 rotates, it drives the first spur gear 29 to rotate, and drives the second spur gear 30 to rotate by the meshing of the first spur gear 29 and the second spur gear 30, thereby driving the third countershaft 28 to rotate;

[0074] When the third countershaft 28 rotates, it drives the first bevel gear 33 to rotate, and drives the first bevel gear ring 32 to rotate by the meshing of the first bevel gear ring 32 and the first bevel gear 33, thereby driving the fourth countershaft 31 to rotate.

[0075] 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 water inside the non-woven fabric is removed by squeezing the non-woven fabric through the relative movement of two clamping plates 53 before drying. The spunlace non-woven fabric with the internal water removed 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 so as to keep the non-woven fabric fluffy during drying, thereby cooperating with the intermittent forward conveying of the non-woven fabric to realize the continuous drying operation of the non-woven fabric.

[0076] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic features of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
