Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric processing equipment, and in particular to an embossing roller for nonwoven fabric surfaces with raised and recessed textures. Background Technology

[0002] Nonwoven fabric, as a widely used industrial and household material, often requires embossing in the later stages of production to increase its surface friction, aesthetics, or achieve specific composite functions. This core process mainly relies on embossing roller devices, which typically use rollers set at the top and bottom to relatively compress the nonwoven fabric passing between them, thereby forming a predetermined texture on the fabric surface.

[0003] However, existing nonwoven fabric embossing equipment still has some shortcomings in its structural design. These are mainly reflected in the lack of flexibility in roller height adjustment and ease of mold replacement. Traditional embossing devices, in pursuit of rigid support, typically use a relatively fixed connection method for the roller bearings. When dealing with nonwoven fabrics of different thicknesses or requiring precise control of embossing depth, there is a lack of a lifting mechanism that can quickly and accurately adjust the roller gap. This results in a cumbersome adjustment process and difficulty in ensuring consistent height on both sides, thus affecting embossing quality. Furthermore, the surface texture layer of existing embossing rollers is often integrated with the roller body or uses an interference fit. When production tasks change and different patterns need to be switched, operators often have to disassemble and replace the entire heavy roller shaft system. This not only greatly increases the labor intensity of workers, prolongs downtime for line changes, and reduces production efficiency, but also frequently disassembling and assembling can easily lead to wear and loosening of the connecting parts, making it difficult to meet the requirements of modern nonwoven fabric production for high efficiency, flexibility, and stable finished product quality.

[0004] Therefore, this utility model proposes an embossing roller for nonwoven fabric surfaces with raised and recessed textures to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems that exist in existing nonwoven fabric embossing equipment, such as poor roller height adjustment flexibility, making it difficult to accurately control the embossing depth according to the fabric thickness, and the need to disassemble the entire roller shaft system when changing the embossing pattern mold, resulting in cumbersome operation, time-consuming and labor-intensive operation and low production efficiency, this utility model aims to provide an embossing roller for nonwoven fabric surfaces with an improved structure that can effectively solve the above problems.

[0006] This utility model provides an embossing roller for nonwoven fabric with a textured surface, comprising: a fixed plate, an extrusion column rotatably connected to the top of the inner wall of the fixed plate, and a motor fixedly connected to the right side of the extrusion column.

[0007] The inner wall of the fixing plate is slidably connected to a fixing column, the outer wall of the fixing column is rotatably connected to a connecting column, the connecting column is disposed on the inner wall of the hollow column, the inner wall of the connecting column is slidably connected to a connecting plate, and the outer wall of the connecting plate is fixedly connected to a convex-concave plate, the convex-concave plate passing through the surface of the hollow column to emboss the non-woven fabric located between the hollow column and the extrusion column.

[0008] Furthermore, a rotating column is rotatably connected to the bottom of the inner wall of the fixing plate, a threaded column is threadedly connected to the inner wall of the rotating column, a support pad is fixedly connected to the top of the threaded column, and the top of the support pad abuts against the bottom of the fixing column to support the fixing column. The height of the fixing column, the connecting column, and the concave-convex plate is adjusted by the cooperation of the rotating column and the threaded column.

[0009] Preferably, the outer wall of the rotating column is provided with a limiting groove, and the inner wall of the limiting groove is slidably connected with a buckle. The end of the buckle away from the limiting groove can be inserted into the inside of the fixing plate to limit the rotation of the rotating column after the height adjustment is completed, and to prevent the threaded column from falling back automatically.

[0010] Preferably, threaded grooves are provided on both the left and right sides of the outer wall of the fixing column, and nuts are threadedly connected to the outer wall of the threaded grooves. One side of the nut abuts against the surface of the fixing plate to lock the fixing column on the fixing plate and prevent it from shifting horizontally.

[0011] Preferably, the outer wall of the connecting post is threaded with a screw, one end of which passes through the connecting post and abuts against the outer wall of the connecting plate, for fixing the connecting plate to the inner wall of the connecting post. When the screw is loosened, the connecting plate can drive the convex and concave plates to slide out for replacement.

[0012] Preferably, a support frame is fixedly connected to the bottom of the motor, and the end of the support frame away from the motor is connected to the fixed plate to share the weight of the motor and reduce vibration.

[0013] Preferably, the connecting column is located at the axial center of the hollow column, the outer wall of the hollow column has a through groove for the protruding plate to extend out, and a gap for placing non-woven fabric is formed between the extrusion column and the hollow column.

[0014] Preferably, the inner wall of the fixing plate is provided with a guide structure, the fixing post slides along the vertical direction of the inner wall of the fixing plate, and the height of the fixing post is determined by the height of the threaded post.

[0015] Preferably, the threaded post is coaxially arranged with the rotating post, and the threaded post moves up and down in the vertical direction as the rotating post rotates, thereby driving the support pad and the fixed post to move up and down.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem of uneven embossing depth caused by the difficulty in adjusting the gap of the embossing rollers in the existing device by setting a lifting and adjusting structure of rotating column, threaded column and support pad. It achieves the effect of flexibly adjusting the distance between hollow column and extrusion column according to the thickness requirements of non-woven fabric, thereby achieving precise control of embossing depth.

[0018] 2. This utility model solves the problem of roller height automatically falling back or horizontal position shifting easily in long-term operation or vibration environment by setting a limiting groove and buckle on the outer wall of the rotating column and setting a threaded groove and nut on the outer wall of the fixed column as a double limiting mechanism. This achieves the effect of effectively locking the position of the embossing component and ensuring the structural stability and alignment accuracy during the embossing operation.

[0019] 3. This utility model solves the problem of cumbersome and time-consuming replacement of existing embossing molds by adopting a modular connection method that uses a sliding connection plate on the inner wall of the connecting column and fixation with screws. It achieves the goal of quickly sliding out and replacing different textured embossed plates simply by loosening the screws, which significantly simplifies the mold assembly and disassembly process and improves production efficiency and equipment versatility.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example

[0029] Please refer to Figures 1 to 5 This utility model provides an embossing roller for textured nonwoven fabric surfaces, aiming to solve the problems of inconvenient roller height adjustment and cumbersome mold replacement in existing nonwoven fabric embossing devices, resulting in low production efficiency. Figure 1 As shown, the embossing roller for the textured nonwoven fabric surface includes a fixed plate 1 and an extrusion column 2 rotatably connected to the top of the inner wall of the fixed plate 1. The fixed plate 1 serves as the mounting base and frame of the entire device, and the inner wall has a space for the installation and sliding of internal components. The extrusion column 2 is horizontally mounted above the fixed plate 1 and is used to cooperate with the components below to convey and reverse extrude the nonwoven fabric. A motor 4 is fixedly connected to the right side of the extrusion column 2. The motor 4 serves as a power source to provide rotational power to the extrusion column 2. A support frame 3 is fixedly connected to the bottom of the motor 4. The end of the support frame 3 away from the motor 4 is connected to the outer wall of the fixed plate 1. The support frame 3 is used to provide stable support for the motor 4 to ensure the stability of power transmission and prevent the motor 4 from being suspended and causing vibration or breakage at the connection.

[0030] A fixed column 5 is slidably connected to the inner wall of the fixed plate 1. The fixed column 5 serves as the height adjustment carrier for the embossing component below and can move vertically along the inner wall of the fixed plate 1. A connecting column 7 is rotatably connected to the outer wall of the fixed column 5. The connecting column 7 is located on the inner wall of the hollow column 10. The hollow column 10 is coaxially sleeved on the outer periphery of the connecting column 7 and has an axially extending through groove on its surface. A connecting plate 8 is slidably connected to the inner wall of the connecting column 7. A concave-convex plate 9 is fixedly connected to the outer wall of the connecting plate 8. The concave-convex plate 9 extends through the through groove on the surface of the hollow column 10 and has a textured structure for pressing nonwoven fabric. The connecting column 7 is located at the axial center of the hollow column 10. A gap for placing nonwoven fabric is formed between the extrusion column 2 and the hollow column 10. By adjusting the height position of the fixed column 5 on the inner wall of the fixed plate 1, the connecting column 7, the hollow column 10, and the concave-convex plate 9 can be raised and lowered as a whole, thereby changing the distance between the hollow column 10 and the extrusion column 2 to adapt to the embossing requirements of nonwoven fabrics of different thicknesses.

[0031] To address the technical problems of accurately controlling the embossing depth of nonwoven fabrics and the tendency for roller positions to shift during device operation, a rotating column 12 and a threaded column 13 are also included, located below the inner wall of the fixed plate 1. The rotating column 12 and the threaded column 13 cooperate to form a height adjustment support mechanism for the fixed column 5. Please refer to [reference needed]. Figure 5 The rotating column 12 is rotatably connected to the bottom of the inner wall of the fixed plate 1. The inner wall of the rotating column 12 is machined with internal threads. The inner wall of the rotating column 12 is threadedly connected to a threaded column 13. A support pad 14 is fixedly connected to the top of the threaded column 13. The top of the support pad 14 is in contact with the bottom surface of the fixed column 5 and forms an abutment fit. The rotating column 12 is used as an active driving component for height adjustment. By rotating the rotating column 12 manually or with tools, the threaded column 13 is driven to rise or fall vertically inside the rotating column 12 using the thread transmission principle. The threaded column 13 pushes the fixed column 5 to slide on the inner wall of the fixed plate 1 through the support pad 14, thereby realizing stepless adjustment of the height of the fixed column 5 and the embossed components above it. Meanwhile, a limiting groove 15 is provided on the outer wall of the rotating column 12 along the axial direction. A buckle 16 is slidably connected to the inner wall of the limiting groove 15. The shape of the buckle 16 is adapted to the shape of the limiting groove 15. The inner wall of the fixing plate 1 is provided with a fixing hole or groove structure for the buckle 16 to be inserted at the corresponding position. After the height of the fixing column 5 is adjusted, the end of the buckle 16 away from the limiting groove 15 is inserted into the inner wall of the fixing plate 1. The buckle 16 cooperates with the limiting groove 15 to restrict the rotational freedom of the rotating column 12 relative to the fixing plate 1. This mechanical anti-rotation cooperation structure formed by the limiting groove 15 and the buckle 16 ensures that the rotating column 12 will not rotate due to the vibration of the motor 4 or the extrusion reaction force when the device is performing embossing operations, prevents the height of the threaded column 13 from automatically falling back, and ensures the constancy of the embossing gap between the hollow column 10 and the extrusion column 2 as well as the uniformity of the embossing texture depth.

[0032] As a preferred embodiment, to prevent the fixed post 5 from shifting horizontally after height adjustment and during operation, thus affecting the embossing alignment accuracy, please refer to... Figure 1 and Figure 4 The fixed column 5 has threaded grooves 6 on both the left and right sides of its outer wall. The fixed plate 1 has an elongated through hole for vertical movement corresponding to the threaded grooves 6. The threaded grooves 6 extend through the elongated through holes to the outside of the fixed plate 1. A nut 11 is threadedly connected to the outer wall of the threaded grooves 6. The side surface of the nut 11 closest to the fixed plate 1 contacts and abuts against the outer surface of the fixed plate 1. After the height of the fixed column 5 is adjusted to the predetermined position, the nut 11 is tightened with a tool, so that the nut 11 moves along the threaded grooves 6 toward the fixed plate 1 and presses tightly against the surface of the fixed plate 1. The axial clamping force between the nut 11 and the fixed plate 1 locks the fixed column 5 to the inner wall of the fixed plate 1. The sliding groove on the inner wall of the fixed plate 1 restricts the degree of freedom of the fixed column 5, thereby ensuring the stability of the entire embossing assembly in the horizontal direction.

[0033] As another preferred embodiment, in order to facilitate the quick replacement of embossed plates 9 with different textures according to production needs and simplify the mold assembly and disassembly process, the outer wall of the connecting column 7 is provided with a threaded hole that extends to the inner wall. A screw 17 is threaded into the threaded hole. The end of the screw 17 passes through the wall of the connecting column 7 and directly abuts against the outer wall of the connecting plate 8. The connecting plate 8 is fixed to the inner wall of the connecting column 7 by the tightening action of the screw 17. When it is necessary to replace the embossed plate 9, the screw 17 is loosened to release the clamping force on the connecting plate 8. The connecting plate 8 can then drive the embossed plate 9 to slide out along the inner wall of the connecting column 7, thereby realizing the quick replacement of the embossing mold.

[0034] As another preferred embodiment, in order to improve the stability of the power source installation and prevent the motor 4 from vibrating due to cantilever installation, please refer to... Figure 1 A support frame 3 is fixedly connected to the bottom of the motor 4. The support frame 3 is preferably a rigid metal rod. The end of the support frame 3 away from the motor 4 is fixedly connected to the outer wall of the fixed plate 1. The support frame 3, the fixed plate 1 and the motor 4 together form a triangular support structure, which effectively shares the weight load of the motor 4, reduces the vibration amplitude of the motor 4 during operation and ensures the smooth rotation of the extrusion column 2.

[0035] Working principle: A pressing column 2 is rotatably connected to the fixed plate 1. A motor 4 is fixedly connected to the right side of the pressing column 2. A support frame 3 is fixedly connected to the bottom of the motor 4. A fixed column 5 is slidably connected to the inner wall of the fixed plate 1. Threaded grooves 6 are opened on both the left and right sides of the outer wall of the fixed column 5. Nuts 11 are threadedly connected to the outer wall of the threaded grooves 6. A connecting column 7 is rotatably connected to the outer wall of the fixed column 5. A connecting plate 8 is slidably connected to the inner wall of the connecting column 7. A concave-convex plate 9 is fixedly connected to the outer wall of the connecting plate 8. Screws 17 are threadedly connected to the outer wall of the connecting column 7. The connecting column 7 is located on the inner wall of the hollow column 10. A rotating column 12 is rotatably connected to the inner wall of the fixed plate 1. A threaded column 13 is threadedly connected to the inner wall of the rotating column 12. A support pad 14 is fixedly connected to the top of the threaded column 13. A limit groove 15 is opened on the outer wall of the rotating column 12. A retaining clip is slidably connected to the inner wall of the limit groove 15. With buckle 16, the motor 4 is started to drive the extrusion column 2 to rotate. The support frame 3 supports the motor 4. The height of the threaded column 13 is adjusted by rotating the rotating column 12. The support pad 14 supports the fixed column 5 and controls the height of the fixed column 5 on the inner wall of the fixed plate 1. When the appropriate height is adjusted, buckle 16 is inserted into the limiting groove 15 and the fixed plate 1 to limit the rotating column 12 and prevent the threaded column 13 from falling. When the nut 11 is rotated, the fixed column 5 is prevented from shifting on the inner wall of the fixed plate 1. The connecting plate 8 slides on the inner wall of the connecting column 7 and can be replaced. Screw 17 fixes the connecting plate 8 and the connecting column 7, thereby placing the non-woven fabric between the extrusion column 2 and the hollow column 10. The height of the fixed column 5 is adjusted to control the space between the hollow column 10 and the extrusion column 2, and the non-woven fabric is extruded. The embossed plate 9 embosses the non-woven fabric.
