Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a pressing device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric is a highly flexible material widely used in medical, hygiene, and filtration fields. In the preparation of nonwoven fabrics, lamination is a common method, typically involving pressing multiple layers of nonwoven fabric together to achieve more complex structures and functions.

[0003] However, if one layer of multi-layer nonwoven fabric is not smoothed before lamination, resulting in wrinkles or unevenness, the final nonwoven fabric product will often exhibit unevenness and bumps after lamination. This not only affects the surface appearance quality of the product but may also reduce its overall practicality and durability. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide a pressing equipment for nonwoven fabric production, which reduces the unevenness that occurs after nonwoven fabric is pressed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressing device for nonwoven fabric production, comprising a support frame, wherein a guide roller group, a pressing component and a winding component are sequentially arranged along a first direction;

[0006] The guide roller assembly includes a first roller and a second roller arranged along a first direction;

[0007] A wrinkle-removing component is disposed between the first roller and the second roller, and is respectively disposed on both sides of the nonwoven fabric along the first direction, for smoothing out wrinkles on the nonwoven fabric;

[0008] The wrinkle-removing component includes a housing, a first pulley group, and a second pulley group. The first pulley group and the second pulley group are respectively disposed on both sides of the nonwoven fabric along a second direction. The housing is provided with a drive unit for driving the first pulley group and the second pulley group to rotate. The first pull belt on the first pulley group and the second pull belt on the second pulley group move toward one side of the nonwoven fabric along a third direction.

[0009] Furthermore, the first pulley assembly includes a first positioning plate, on which a first driving roller and a first driven roller are rotatably disposed, both of which are located within the first pull belt; the second pulley assembly includes a second positioning plate, on which a second driving roller and a second driven roller are rotatably disposed, both of which are located within the second pull belt.

[0010] Furthermore, the drive unit includes a first gear for driving the first drive roller to rotate, a second gear for driving the second drive roller to rotate, the first gear and the second gear being meshed together, and a motor for driving the first gear to rotate.

[0011] Furthermore, the wrinkle-removing component also includes an adjustment part for adjusting the distance between the first pulley set and the second pulley set.

[0012] Furthermore, the adjustment unit includes a cylinder for driving the second positioning plate to move in the second direction. A through hole is opened in the middle of the second gear, and a magnetic ring is fixedly installed on the inner wall of the through hole. An iron wheel is provided in the middle of the second gear. The outer diameter of the iron wheel is smaller than the inner diameter of the magnetic ring. The side of the iron wheel shaft is fixedly connected to the side of the second drive roller shaft.

[0013] Furthermore, the first positioning plate is fixedly connected to the outer shell, and the second positioning plate is slidably disposed on the outer shell.

[0014] Furthermore, a guide block is fixedly installed on the second positioning plate, the moving end of the cylinder is fixedly connected to the guide block, and a guide groove for sliding of the guide block is provided on the outer shell.

[0015] Furthermore, multiple ball bearings are rotatably provided on the surfaces of the first and second pull belts.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: The nonwoven fabric is guided and oriented by the first and second rollers on the support, and then its surface is smoothed and wrinkled by a wrinkle-removing component located between the first and second rollers. Specifically, the wrinkle-removing component works by a drive unit that rotates the first and second pulley sets, causing the first pull belt on the first pulley set and the second pull belt on the second pulley set to move towards the nonwoven fabric in a third direction, thereby smoothing out the wrinkles. Next, the wrinkle-removed nonwoven fabric is further pressed and compacted by a pressing component, and then wound up by a winding component. In this way, the entire nonwoven fabric production process achieves flatness, compactness, and continuous winding of the nonwoven fabric, ensuring pressing quality and improving production efficiency.

[0023] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1 This embodiment provides a pressing device for nonwoven fabric production, including a support 1. The support 1 is sequentially arranged with a guide roller group 2, a pressing component 3, and a winding component 4 along a first direction. When pressing two or more layers of nonwoven fabric into one layer, each layer of nonwoven fabric is first guided by the guide roller group 2 to the pressing component 3, where the pressing component 3 performs the pressing process on the nonwoven fabric. Then, the pressed nonwoven fabric is wound up by the winding component 4.

[0025] It should be noted that if one layer of nonwoven fabric is not smoothed before pressing, wrinkles or unevenness may occur. After pressing, the final nonwoven fabric product often exhibits unevenness and bumps.

[0026] Please see Figure 1 To solve the aforementioned technical problems, the guide roller group 2 includes a first roller 21 and a second roller 22 arranged along a first direction; wherein the first direction is the fabric movement direction, that is, along the length of the fabric.

[0027] Please see Figure 2 and Figure 3A wrinkle-removing component 5 is disposed between the first roller 21 and the second roller 22, and is respectively disposed on both sides of the nonwoven fabric along a first direction, for smoothing wrinkles on the nonwoven fabric; wherein the wrinkle-removing component 5 includes a housing 51, a first pulley group 52 and a second pulley group 53, the first pulley group 52 and the second pulley group 53 being respectively disposed on both sides of the nonwoven fabric along a second direction. The second direction is a direction perpendicular to the plane of the fabric. Figure 1 In the middle, the second direction between the first roller 21 and the second roller 22 is the vertical direction.

[0028] Please see Figure 3 and Figure 4 The outer casing 51 is provided with a drive unit 54 for rotating the first pulley group 52 and the second pulley group 53; the first pull belt 524 on the first pulley group 52 and the second pull belt 534 on the second pulley group 53 move along a third direction toward the nonwoven fabric. The third direction is perpendicular to the first direction and the second direction, that is, the direction from the middle of the nonwoven fabric toward the edge.

[0029] The nonwoven fabric is directionally moved by the first roller 21 and the second roller 22 on the support 1, and then its surface is smoothed by the wrinkle-removing component 5 located between the first roller 21 and the second roller 22. Specifically, the wrinkle-removing component 5 works by the drive unit 54 driving the first pulley group 52 and the second pulley group 53 to rotate, causing the first pull belt 524 on the first pulley group 52 and the second pull belt 534 on the second pulley group 53 to move towards the nonwoven fabric in a third direction, thereby smoothing out the wrinkles on the nonwoven fabric. Next, the wrinkle-removed nonwoven fabric continues to be pressed tightly by the pressing component 3, and then wound up by the winding component 4. In this way, the entire nonwoven fabric production process achieves flatness, tightness, and continuous winding of the nonwoven fabric, ensuring pressing quality and improving production efficiency.

[0030] The first pull strap 524 and the second pull strap 534 are relatively long along the first direction, ranging from 50cm to 60cm. Within this range, the nonwoven fabric can be smoothed, ensuring that the force of the two pull straps can be continuously and stably applied to the nonwoven fabric.

[0031] Please see Figure 3 , Figure 4 and Figure 5 The first pulley assembly 52 includes a first positioning plate 521, on which a first driving roller 522 and a first driven roller 523 are rotatably disposed, both of which are located within the first pull belt 524; the second pulley assembly 53 includes a second positioning plate 531, on which a second driving roller 532 and a second driven roller 533 are rotatably disposed, both of which are located within the second pull belt 534.

[0032] The first positioning plate 521 supports the various components on the first pulley assembly 52. ​​The first driving roller 522 drives the first tension belt 524 to move, and the first driven roller 523 supports the first tension belt 524. The second positioning plate 531 supports the various components on the second pulley assembly 53. The second driving roller 532 drives the second tension belt 534 to move, and the second driven roller 533 supports the second tension belt 534.

[0033] Please see Figure 2 - Figure 4 The drive unit 54 includes a first gear 541 for driving the first drive roller 522 to rotate, a second gear 542 for driving the second drive roller 532 to rotate, the first gear 541 and the second gear 542 are meshed together, and also includes a motor 543 for driving the first gear 541 to rotate.

[0034] Motor 543 drives the first gear 541 to rotate, and the first gear 541 drives the second gear 542 to rotate. During the rotation, the tangential movement direction of the meshing point of the first gear 541 and the second gear 542 is the same, which also makes the movement direction of the opposite surfaces of the first pull belt 524 and the second pull belt 534 the same. They are both moving from the middle of the nonwoven fabric to the edge of the nonwoven fabric.

[0035] In the production process of nonwoven products, different types of nonwoven fabrics often exhibit different thicknesses due to differences in raw materials and production processes. In order to facilitate the flattening of nonwoven fabrics of different thicknesses.

[0036] Please see Figure 2 - Figure 4 The wrinkle-removing component 5 further includes an adjustment part 55 for adjusting the distance between the first pulley group 52 and the second pulley group 53. The adjustment part 55 includes a cylinder 551 for driving the second positioning plate 531 to move in a second direction. The distance between the first pulley group 52 and the second pulley group 53 is adjusted by adjusting the position of the second positioning plate 531 through the cylinder 551.

[0037] To facilitate adjusting the distance between the first pulley group 52 and the second pulley group 53 while maintaining their transmission relationship, a through hole 552 is provided in the middle of the second gear 542. A magnetic ring 553 is fixedly installed on the inner wall of the through hole 552. An iron wheel 554 is provided in the middle of the second gear 542. The outer diameter of the iron wheel 554 is smaller than the inner diameter of the magnetic ring 553. The side of the iron wheel 554 is fixedly connected to the side of the second drive roller 532.

[0038] The second gear 542 is rotatably mounted on the outer casing 51, so it is always in mesh with the first gear 541. When the second positioning plate 531 moves, that is, when the second pulley group 53 moves, the second drive roller 532 also moves, thereby driving the iron wheel 554 to move within the through hole 552, that is, the iron wheel 554 to move within the magnetic ring 553. When the second gear 542 rotates, the magnetic ring 553 drives the iron wheel 554 to rotate, which in turn drives the second drive roller 532 to rotate together, thereby driving the second pull belt 534 to move. This allows for free adjustment of the distance between the first pulley group 52 and the second pulley group 53 while maintaining their transmission relationship.

[0039] Please see Figure 2 and Figure 3 To facilitate the movement of the second pulley assembly 53, the first positioning plate 521 is fixedly connected to the outer casing 51, and the second positioning plate 531 is slidably disposed on the outer casing 51. A guide block 56 is fixedly installed on the second positioning plate 531, and the moving end of the cylinder 551 is fixedly connected to the guide block 56. A guide groove 57 for sliding of the guide block 56 is provided on the outer casing 51. When the second positioning plate 531 moves, it causes the guide block 56 to slide within the guide groove 57. Through the sliding relationship between the guide block 56 and the guide groove 57, the second positioning plate 531 is limited to a certain extent.

[0040] To reduce wear on the nonwoven fabric caused by the first pull strap 524 and the second pull strap 534, multiple rolling balls 58 are rotatably arranged on the surfaces of the first pull strap 524 and the second pull strap 534. This changes sliding friction into rolling friction, reducing scratches on the nonwoven fabric.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
