Description

Technical Field

[0001] This invention belongs to the field of nonwoven fabric technology, specifically relating to a nonwoven fabric coating and drying mechanism. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, or needle-punched non-woven fabric, is made from polyester fibers and manufactured through a needle-punching process, allowing for different thicknesses, textures, and hardnesses. Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, lightness, flame retardancy, non-toxicity, odorlessness, low cost, and recyclability. They can be used in various industries, such as sound insulation, heat insulation, heating elements, masks, clothing, medical applications, and as filling materials.

[0003] In nonwoven fabric coating, the drying effect after coating directly affects product quality. Traditional nonwoven fabric coating drying equipment has many limitations: some equipment relies on a single heating roller for drying, making it difficult to ensure uniform heating of the coating layer, easily leading to incomplete drying or damage to the coating layer due to localized overheating; moreover, the spacing between heating rollers is mostly fixed, making it unsuitable for nonwoven fabrics of different thicknesses, requiring frequent equipment or component changes when processing products of different specifications, resulting in cumbersome operation, poor versatility, and severely impacting production efficiency; simultaneously, the lack of auxiliary air-drying structures means that relying solely on heating drying not only consumes high energy but may also cause production delays due to insufficient drying speed, making it difficult to ensure a stable and efficient drying process. Based on the above problems, this application proposes a nonwoven fabric coating drying mechanism to improve these issues. Utility Model Content

[0004] The purpose of this invention is to provide a nonwoven fabric coating and drying mechanism that dries the nonwoven fabric by heat conduction between a first heating roller and a second heating roller. In addition, a first motor drives the adjustment of the distance between the two rollers to adapt to different thickness requirements and ensure stable and efficient drying.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A nonwoven fabric coating and drying mechanism includes a base, with support rods fixed to both sides of the upper end of the base. A first movable block and a second movable block are sequentially arranged inside the two support rods from top to bottom. A first heating roller is rotatably connected between the two first movable blocks, and a second heating roller is rotatably connected between the two second movable blocks. A support plate is fixed to one side of one support rod, and a first motor is fixed to the upper end of the support plate. A threaded rod is fixed to the output end of the first motor, and a connecting plate is threadedly connected to the outer side of the threaded rod. One side of the connecting plate is fixedly connected to the first movable block. The mechanism also includes:

[0007] A drying mechanism is mounted on the upper end of the base and located at one end of the support rod.

[0008] In a preferred embodiment, a limit rod is fixed inside each of the two support rods, and the upper end of the limit rod passes through the upper end of the first movable block.

[0009] In a preferred embodiment, a spring is fixed to the upper end of the second movable block, and the spring is located between the first and second movable blocks, with the spring located outside the limiting rod.

[0010] In a preferred embodiment, each of the two support rods has a baffle at its upper end, and the baffle and the support rod are fixedly connected by bolts.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale.

[0025] Please see the appendix Figure 1 and Figure 3 As shown, this utility model provides a non-woven fabric coating and drying mechanism, including a base 10, with support rods 11 fixed on both sides of the upper end of the base 10. A first moving block 12 and a second moving block 13 are sequentially arranged inside the two support rods 11 from top to bottom. A first heating roller 14 is rotatably connected between the two first moving blocks 12, and a second heating roller 15 is rotatably connected between the two second moving blocks 13. A support plate 16 is fixed to one side of one support rod 11, and a first motor 17 is fixed to the upper end of the support plate 16. A threaded rod 18 is fixed to the output end of the first motor 17, and a connecting plate 19 is threadedly connected to the outer side of the threaded rod 18. One side of the connecting plate 19 is fixedly connected to the first moving block 12. The mechanism also includes:

[0026] The air drying mechanism 30 is mounted on the upper end of the base 10 and located at one end of the support rod 11.

[0027] In this embodiment, during operation, the first motor 17 is started to drive the threaded rod 18 to rotate, causing the threaded connecting plate 19 to move the first moving block 12 up and down within the support rod 11, thereby adjusting the distance between the first heating roller 14 and the second heating roller 15. When the nonwoven fabric passes between the first heating roller 14 and the second heating roller 15, the heating and drying after coating is completed through heat conduction. The air-drying mechanism 30 at one end of the support rod 11 can dry the nonwoven fabric between the first heating roller 14 and the second heating roller 15. By combining heating and air drying, defects such as bubbles and cracks in the coating layer can be avoided, ensuring uniform and stable drying. The overall structure is compact and easy to operate, effectively improving production efficiency and product qualification rate. It should be noted that the first heating roller 14 and the second heating roller 15 are existing technologies, and their specific working principles will not be described in detail.

[0028] In a preferred embodiment, please refer to Figure 3 Both support rods 11 have a limit rod 20 fixed inside, and the upper end of the limit rod 20 passes through the upper end of the first moving block 12.

[0029] In this embodiment, during operation, the first motor 17 drives the threaded rod 18 to rotate, causing the connecting plate 19 to drive the first moving block 12 to move up and down along the limiting rod 20 inside the support rod 11. The limiting rod 20 can ensure that the first moving block 12 moves smoothly, avoid the first heating roller 14 from shifting and affecting the drying effect, and can flexibly adapt to non-woven fabrics of different thicknesses.

[0030] Secondly, please refer to it again. Figure 3 A spring 21 is fixed to the upper end of the second moving block 13, and the spring 21 is located between the first moving block 12 and the second moving block 13. The spring 21 is located outside the limiting rod 20.

[0031] In this embodiment, when the first moving block 12 moves downward, it can compress the spring 21. The elastic force generated by the spring 21 can push the second moving block 13 to fit more firmly against the support rod 11, ensuring the stability of the position of the second heating roller 15.

[0032] Secondly, please refer to the following as well. Figure 3 Both support rods 11 are equipped with baffles 22 at their upper ends, and the baffles 22 and the support rods 11 are fixedly connected by bolts.

[0033] In this embodiment, the baffles 22, which are fixed to the upper ends of the two support rods 11 by bolts, can effectively limit the upward movement range of the first moving block 12, preventing it from dislodging from the limiting rods 20 or damaging the components due to excessive movement. When maintenance is required on the first heating roller 14 and the second heating roller 15, the baffles 22 can be removed by unscrewing the fixing bolts, making it easy to take the first moving block 12 and the first heating roller 14 out of the support rods 11, thus facilitating maintenance operations.

[0034] To further understand and explain, Figure 1 and Figure 2 For example, the air drying mechanism 30 includes a side plate 31, a hot air blower 32 and an air outlet 33. The side plate 31 is fixed to the upper end of the base 10, the hot air blower 32 is fixed to the end of the side plate 31 near the support rod 11, and the air outlet 33 is fixed to the lower end of the hot air blower 32.

[0035] In this embodiment, the side plate 31 fixed to the upper end of the base 10 in the drying mechanism 30 supports the hot air blower 32. The airflow generated by the hot air blower 32 is blown onto the non-woven fabric through the air outlet 33 at the lower end. The drying mechanism 30 can make the hot air act on the non-woven fabric and accelerate the evaporation of moisture on the non-woven fabric.

[0036] In a preferred embodiment, please refer to Figure 2 The side plate 31 is rotatably connected to a rotating roller 34, and the rotating roller 34 is located at the lower end of the air outlet 33.

[0037] In this embodiment, the rotating roller 34 can assist in the smooth transport of the nonwoven fabric, so that the hot air can act more evenly on the surface of the nonwoven fabric.

[0038] Secondly, please refer to it again. Figure 1 Support frames 35 are fixed on both sides of the upper end of the base 10. The two support frames 35 are located at the end of the support rod 11 away from the drying mechanism 30. A load-bearing plate 36 is fixed on one side of one support frame 35. A second motor 37 is fixed on the upper end of the load-bearing plate 36. A take-up roller 38 is rotatably connected between the two support frames 35. One end of the take-up roller 38 extends to the outside of the support frame 35, and the output end of the second motor 37 is fixedly connected to the take-up roller 38.

[0039] In this embodiment, during operation, the second motor 37 drives the take-up roller 38 to rotate, thereby winding up the dried nonwoven fabric. Driven by the second motor 37, the take-up roller 38 enables automatic winding of the nonwoven fabric, avoiding the tediousness and irregularity of manual winding.

[0040] The working principle of this utility is as follows:

[0041] The first motor 17 drives the threaded rod 18 to rotate, which in turn drives the connecting plate 19 and the first moving block 12 to move up and down along the limiting rod 20 inside the support rod 11, adjusting the distance between the first heating roller 14 and the second heating roller 15 to accommodate non-woven fabrics of different thicknesses. When the first moving block 12 moves down, it compresses the spring 21. The elastic force of the spring 21 pushes the second moving block 13 to firmly support the second heating roller 15, ensuring its stable position. The baffle 22 at the upper end of the support rod 11 limits the upward range of the first moving block 12, and also facilitates later maintenance. During the conveying process, the nonwoven fabric is first processed by the air-drying mechanism 30. The airflow generated by the hot air blower 32 supported by the side plate 31 blows onto the nonwoven fabric located on the lower rotating roller 34 through the air outlet 33, accelerating the evaporation of moisture. Then, the nonwoven fabric enters between the first heating roller 14 and the second heating roller 15, and completes the heating and drying after coating through heat conduction. Finally, the dried nonwoven fabric is automatically wound up by the second motor 37 on the support frame 35 driving the winding roller 38, realizing a continuous operation process from adjustment and adaptation, air drying and heating to winding.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
