[0029] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0030] like Figure 1 As shown, in one embodiment of this utility model, the nonwoven fabric coating device includes a frame 100 and a drying mechanism 500, a discharge mechanism 300, at least one conveying mechanism 200, and at least one coating mechanism 400 respectively connected to the frame 100; the coating mechanism 400 is disposed between the drying mechanism 500 and the conveying mechanism 200; and the coating mechanism 400 includes a guide component 410 and a spray component 420, and a spray gap is provided between the guide component 410 and the spray component 420, the spray gap being used to guide and spray the nonwoven fabric; the discharge mechanism 300 is disposed on the side of the conveying mechanism 200 away from the corresponding coating mechanism 400.

[0031] The technical solution of this utility model improves the smoothness and stability of conveying by using a conveying mechanism to transport non-woven fabric and a guiding component to guide the conveying of non-woven fabric. Furthermore, by combining the spraying operation of the spraying component with the drying treatment of the drying mechanism, and then using the discharge mechanism for discharge operation, the smoothness and stability of operation can be ensured, and the spraying quality can be improved.

[0032] Specifically, in some implementations, such as Figure 1As shown, the number of conveying mechanisms 200 is at least two; the number of coating mechanisms 400 is at least two; and one coating mechanism 400 is disposed between the drying mechanism 500 and one of the conveying mechanisms 200; the other coating mechanism 400 is disposed between the drying mechanism 500 and the other conveying mechanism 200; the discharge mechanism 300 is disposed on the side of the other conveying mechanism 200 away from the corresponding coating mechanism 400. That is, one conveying mechanism 200, one coating mechanism 400, drying mechanism 500, another coating mechanism 400, another conveying mechanism 200, and discharge mechanism 300 are arranged along the conveying direction of the nonwoven fabric (e.g., ...). Figure 1 (As shown from left to right) are sequentially connected to the frame 100. This structure achieves a dual spraying operation on the nonwoven fabric through the action of initial spraying + drying + re-spraying + natural drying, thereby improving the spraying quality.

[0033] Specifically, in some implementations, such as Figure 1 and 2 As shown, the conveying mechanism 200 includes a height adjustment component 210, a support plate 220, and a rotating conveying component 230. The mounting end of the height adjustment component 210 is connected to the frame 100; the movable end of the height adjustment component 210 is connected to the support plate 220; the rotating conveying component 230 is movably connected to the side surface of the support plate 220 and is used to convey nonwoven fabric. In some embodiments, such as... Figure 2 As shown, the height adjustment component 210 includes a height adjustment cylinder 211, a mounting base 212, and a connecting frame 213. The mounting base 212 (by bonding or welding) is connected to the frame 100. The height adjustment cylinder 211 is connected to the mounting base 212 and (its telescopic shaft) is connected to the connecting frame 213. The support plate 220 is connected to the connecting frame 213. This structure, through the telescopic lifting and lowering movement of the height adjustment cylinder 211, drives the support plate 220 and the rotating conveying component 230 to move downwards or upwards, thereby adjusting the tensile stress on the conveying of the nonwoven fabric, which helps to improve the stability of the conveying. Further, the connecting frame 213 includes multiple vertical support plates arranged in parallel and a horizontal connecting plate connecting two adjacent vertical support plates; each vertical support plate (by bonding or welding) is connected to the support plate 220 to further improve the support stability of the support plate 220.

[0034] In some implementation methods, such as Figure 1 and 2As shown, the rotating conveying component 230 includes a rotating drive assembly, a first conveying roller 233, and a second conveying roller 236. The first conveying roller 233 and the second conveying roller 236 are respectively movably connected to the support disk 220, and the first conveying roller 233 is disposed obliquely below the second conveying roller 236. The rotating drive assembly is connected to the support disk 220; and the rotating drive assembly is drivenly connected to the first conveying roller 233; the rotating drive assembly is tractionally connected to the second conveying roller 236. Further, as... Figure 2 As shown, the rotation drive assembly includes a rotation conveyor motor 231, a first drive wheel 232, a first transmission chain 234, and a first driven wheel 235. The rotation conveyor motor 231 is connected to one side surface of the support disk 220 and is drively connected to the first drive wheel 232 (via a traction wheel). One end of the first conveyor roller 233 is connected to the interior of the first drive wheel 232 (and a first bearing is provided on the side surface of one end of the first conveyor roller 233, which is connected to the interior of the support disk 220). One end of the second conveyor roller 236 is connected to the interior of the first driven wheel 235 (and a second bearing is provided on the side surface of one end of the second conveyor roller 236, which is connected to the interior of the support disk 220). The first transmission chain 234 is connected around the first drive wheel 232 and the first driven wheel 235. Further, as... Figure 2 As shown, the conveying mechanism 200 also includes at least two guide rollers 240; all guide rollers 240 are connected to the inner bottom of the frame 100; and the projections of adjacent guide rollers 240 are staggered; the output end of the second conveying roller 236 is connected to the input end of the guide roller 240. That is, when the rotating conveying motor 231 is started, the first conveying roller 233 and the second conveying roller 236 are rotated and conveyed under the traction of the first driving wheel 232, the first transmission chain 234 and the first driven wheel 235; and the height adjusting cylinder 211 is driven to adjust the height of the first conveying roller 233 and the second conveying roller 236, thereby effectively adjusting the conveying tension stress on the nonwoven fabric; and thus improving the stability of the conveying.

[0035] Specifically, in some implementations, such as Figure 1 and 4 As shown, the guide assembly 410 includes a first guide roller 411, a second guide roller 412, and a tension guide roller 413; the second guide roller 412 and the tension guide roller 413 are sequentially connected side-by-side on the frame 100; the spray gap is formed between the second guide roller 412 and the tension guide roller 413; and a limiting roller is provided above both the second guide roller 412 and the tension guide roller 413 for limiting the conveying of the nonwoven fabric; and the limiting roller is disposed inside the spray gap. In some embodiments, such as... Figure 4As shown, the guide assembly 410 also includes a connecting block 414, a guide rail 415, and a tensioning drive cylinder 416; the guide rail 415 is connected to the frame 100; the mounting end of the tensioning drive cylinder 416 is connected to the frame 100, and the movable end of the tensioning drive cylinder 416 is connected to the connecting block 414; a tensioning guide roller 413 (via a mounting bearing) is connected to the connecting block 414; the side end of the connecting block 414 is slidably connected to the guide rail 415 to quickly adjust the tension of the conveyor. Further, in some embodiments, such as... Figure 4 As shown, the guide assembly 410 also includes a guide drive roller 417; the guide drive roller 417 is movably connected to the frame 100 and is drivenly connected to the second guide roller 412 (via a transmission belt); the guide drive roller 417 is connected to a guide motor; the guide motor is connected to the frame 100.

[0036] Specifically, in some implementations, such as Figure 1 and 3 As shown, the spray assembly 420 includes a storage tank 421, a coating discharge head 422, a conveying pipe 423, and a mounting frame 424. The storage tank 421 is connected to the frame 100, and its output end is connected to one end of the conveying pipe 423. The other end of the conveying pipe 423 is connected to the input end of the coating discharge head 422. The output end of the coating discharge head 422 is located inside the spray gap. The mounting frame 424 is connected to the frame 100. The conveying pipe 423 is snapped into the interior of the mounting frame 424. The coating discharge head 422 is selected from HDPP coating die heads, 750-4200mm coating die heads, or CJ type coating die heads. The output end of the storage tank 421 is equipped with a solenoid control valve (standard model). Further, as... Figure 3 As shown, the conveying pipe 423 is a flexible conveying hose (either entirely or partially flexible). The spraying assembly 420 also includes a guide shaft 425, a positioning seat 426, and a transverse pushing cylinder 427; the mounting end of the transverse pushing cylinder 427 is connected to the mounting bracket 424 and is movably connected to the positioning seat 426; the guide shaft 425 is connected to the side end surface of the mounting bracket 424; and the interior (sliding hole) of the positioning seat 426 is in close contact with the outer surface of the guide shaft 425; the outer side wall of the conveying pipe 423 is in close contact with the interior (limiting hole) of the positioning seat 426. That is to say, in use, the movement of the transverse pushing cylinder 427 can be driven to adjust the horizontal position of the coating discharge head 422 in the conveying direction, thereby adjusting the assembly position with the guide assembly 410, which is beneficial to the quantity and stability of the packaging spray.

[0037] Specifically, in some implementations, such as Figure 1 and 5As shown, the discharge mechanism 300 includes an assembly frame 310, a compression roller 340, and a discharge roller 360; the assembly frame 310 is connected to the frame 100; the compression roller 340 and the discharge roller 360 are arranged side by side in a vertical direction; the compression roller 340 and the discharge roller 360 are movably connected to the assembly frame 310, and a compression conveying gap is provided between the compression roller 340 and the discharge roller 360; the compression conveying gap is used to convey nonwoven fabric. This structure, through the compression roller 340 and the discharge roller 360 arranged side by side, can reduce the jumping during the nonwoven fabric conveying process, thereby improving the stability of the packaging discharge. Wherein, as... Figure 5 As shown, both the extrusion roller 340 and the discharge roller 360 are connected to the assembly frame 310 via discharge bearings; and one end of the discharge roller 360 is connected to a discharge motor; the discharge motor is connected to the assembly frame 310. In some embodiments, such as... Figure 5 As shown, the discharge mechanism 300 also includes an extrusion cylinder 320, a connecting rod 330, a sliding seat 350, and a limiting rail 311. The mounting end of the extrusion cylinder 320 is connected to the assembly frame 310, and the movable end of the extrusion cylinder 320 is connected to one end of the connecting rod 330. The other end of the connecting rod 330 is connected to the sliding seat 350. The limiting rail 311 is connected to the assembly frame 310. The extrusion roller 340 is connected to the sliding seat 350 through a discharge bearing. The sliding seat 350 is slidably connected to the limiting rail 311. In other words, during use, the drive motor of the discharge mechanism drives the discharge roller 360 to rotate and discharge materials. At the same time, the extrusion cylinder 320 is driven so that the sliding seat 350 slides up and down along the limit track 311, thereby adjusting the size of the extrusion conveying gap between the extrusion roller 340 and the discharge roller 360. This reduces the jumping during the nonwoven fabric conveying process and improves the adaptability of discharge for nonwoven fabrics of different specifications and different coating thicknesses, thus improving the stability of packaging discharge.
