Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile equipment and relates to a web laying machine. Background Technology
[0002] In the production of nonwoven fabrics and similar products, web laying machines are key pieces of equipment used to fold and lay out the cotton web to form a cotton layer of a specific thickness. Currently available web laying machines include... Figure 1 As shown, it mainly consists of a web-laying mechanism 1', a first web-conveying mechanism 2', and a second web-conveying mechanism 3'. The first web-conveying mechanism 2' and the second web-conveying mechanism 3' partially intersect and work together to traction and convey the product web.
[0003] However, this design has significant drawbacks. Firstly, during the transport of the product web, a portion is handled separately on the first web conveyor mechanism 2'. When the equipment operates at higher speeds, the web, lacking effective support and constraint, is prone to swaying, severely limiting the increase in equipment speed and consequently affecting production efficiency. Secondly, during the process of folding and laying the web onto the web-laying mechanism 1', the thickness at the bends on both sides of the web is greater than in the middle due to the folding method, resulting in uneven cotton layer thickness and severely impacting the quality of the final product. Utility Model Content
[0004] The purpose of this invention is to provide a web laying machine that, through structural improvements, solves the problem of easy floating of cotton webs during feeding and improves the uniformity of product thickness.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A web laying machine includes a housing with an inlet. Inside the housing are a web laying mechanism, a first web conveying mechanism, and a second web conveying mechanism. A third web conveying mechanism is also provided inside the housing. One end of the third web conveying mechanism extends to the inlet, and the third web on it presses against the first web of the first web conveying mechanism. The first and third webs clamp the cotton web entering from the inlet and move it along a predetermined direction.
[0007] As a further improvement of one embodiment of the present invention, a speed regulating roller is also provided in the machine housing where the feed port is located. The speed regulating roller is driven by a servo motor and cooperates with the feed roller A of the first mesh conveying mechanism. The speed of the speed regulating roller can be adjusted so that it can form a speed difference with the feed roller A, thereby traction and stretching the cotton web at the preset position.
[0008] As a further improvement of one embodiment of the present invention, the first mesh curtain conveying mechanism includes a plurality of mesh-forming guide rollers, on which a first mesh curtain is conveyed; wherein the mesh-forming guide roller near the inlet is a feed roller A, and the mesh-forming guide rollers arranged sequentially along the running direction of the first mesh curtain are a reversing roller A and a dropping roller assembly A; the first mesh curtain between the feed roller A and the reversing roller A is a mesh curtain A, used to intersect with a third mesh curtain; the first mesh curtain between the reversing roller A and the dropping roller assembly A is a mesh curtain B, used to intersect with a second mesh curtain.
[0009] As a further improvement of one embodiment of this utility model, the mesh curtain A is horizontally distributed, and the mesh curtain B is inclined downward along the running direction; the dropping roller assembly A consists of three web-forming guide rollers: dropping roller A, abutting roller A, and traction roller A. The first mesh curtain is sequentially wound around the abutting roller A, traction roller A, and dropping roller A, and the abutting roller A and dropping roller A are arranged adjacent to each other, so that the first mesh curtain between the abutting roller A, traction roller A, and dropping roller A forms an acute angle, and the cotton web on the first mesh curtain directly reaches the dropping roller A from the abutting roller A.
[0010] As a further improvement of one embodiment of the present invention, the third mesh curtain conveying mechanism includes multiple web-forming guide rollers, on which a third mesh curtain is conveyed; the part of the third mesh curtain that is pressed against the mesh curtain A is the mesh curtain C, and along the running direction of the third mesh curtain, the web-forming guide rollers at both ends of the mesh curtain C are the feeding roller B and the dropping roller assembly B, respectively, and the dropping roller assembly B is adjacent to the reversing roller A, so that the cotton web on the mesh curtain A is removed from the third mesh curtain after passing through the dropping roller assembly B.
[0011] As a further improvement of one embodiment of the present invention, the feeding roller assembly B consists of three web-forming guide rollers: feeding roller B, abutting roller B, and traction roller B. The third web is sequentially wound around the abutting roller B, traction roller B, and feeding roller B, with the abutting roller B and feeding roller B arranged adjacent to each other. The third web between the abutting roller B, traction roller B, and feeding roller B is bent at an acute angle. The cotton web is directly conveyed from the abutting roller B to the feeding roller B and falls through the gap between the reversing roller A and the feeding roller B.
[0012] As a further improvement of one embodiment of the present invention, the second mesh curtain conveying mechanism includes a plurality of web-forming guide rollers, on which a second mesh curtain is conveyed; the part of the second mesh curtain that is pressed against the mesh curtain B is the mesh curtain D; along the running direction of the second mesh curtain, the web-forming guide rollers at both ends of the mesh curtain D are respectively a guide roller and a reversing roller B; the reversing roller B is adjacent to the dropping roller assembly A, so that the cotton web on the mesh curtain B falls through the gap between the reversing roller B and the dropping roller A.
[0013] The above technical solution has the following beneficial effects: By setting up the third mesh curtain conveying mechanism, the cotton web can be clamped by the first and third mesh curtains as soon as it enters from the feed port, so that the cotton web is supported and constrained during high-speed operation of the equipment, thus solving the problem of cotton web swaying during high-speed operation; at the same time, the application of the speed regulating roller allows the equipment to orderly pull and stretch the local cotton web through a pre-set time, so that when the cotton web is laid on the web laying mechanism, the thickness at the bends on both sides is basically the same as the thickness in the middle.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0033] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Example
[0034] See Figures 2-5 As shown, a web-laying machine includes a casing 100, which serves as the main frame of the entire device, supporting and protecting the internal components. The casing 100 has an inlet for inputting cotton web. Inside the casing 100 are a web-laying mechanism 1, a first web-curtain conveying mechanism 2, and a second web-curtain conveying mechanism 3. The structure and working principle of the web-laying mechanism 1 are consistent with existing web-laying mechanisms and will not be described further here. The main improvement of this embodiment lies in the optimization of cotton web conveying and processing to meet the demands of high-speed equipment operation and improve the weight uniformity of the product after web laying.
[0035] To achieve the aforementioned improvements, a third mesh conveying mechanism 4 is specially installed inside the casing 100. One end of the third mesh conveying mechanism 4 extends to the inlet, where a third mesh 41 is installed. The third mesh 41 presses against the first mesh 22 of the first mesh conveying mechanism 2. When the cotton web enters from the inlet, the first mesh 22 and the third mesh 41 work closely together to clamp the cotton web and move it along a predetermined direction. This structure ensures that the cotton web receives effective support and constraint from the moment it enters the equipment. During high-speed operation, the cotton web will not sway, ensuring the stability and accuracy of the cotton web conveying and laying a good foundation for subsequent web laying operations.
[0036] Inside the housing 100 at the feed inlet, a speed-regulating roller 5 is also installed. The speed-regulating roller 5 is driven by a servo motor, which can precisely control its rotational speed. The speed-regulating roller 5 cooperates with the feed roller A 21 of the first mesh conveying mechanism 2. Because the speed of the speed-regulating roller 5 is adjustable, it can create a speed difference with the feed roller A 21. When the cotton web passes the preset position between the speed-regulating roller 5 and the feed roller A 21, this speed difference will exert a traction and stretching effect on the cotton web.
[0037] In actual use, the equipment systematically stretches and pulls the cotton web according to a pre-set time. This method results in a more uniform tension distribution across the web after stretching. When the web is conveyed to the web-laying mechanism 1 for laying, the thickness at the bends on both sides remains essentially consistent with the thickness in the middle. This significantly improves the weight uniformity of the product after web laying, leading to more stable product quality and meeting market demands for high-quality products.
[0038] Combination Figure 3 As shown, the first web conveying mechanism 2 is a key component of the web laying machine responsible for conveying the first web 22 to achieve web transfer and web laying operations. This mechanism includes multiple web-forming guide rollers, which together support and guide the movement of the first web 22. One of these guide rollers is driven by a motor, which transmits power to this roller through a transmission device, thereby driving the first web 22 along a predetermined direction, ensuring the stability and controllability of the entire conveying process.
[0039] Among the multiple web-forming guide rollers, the web-forming guide roller closest to the feed inlet is the feed roller A 21, which mainly serves to receive the cotton web entering from the feed inlet and guide it into the first web curtain 22. Along the running direction of the first web curtain 22, the web-forming guide rollers arranged in sequence are the reversing roller A 23 and the discharge roller assembly A. The portion of the first web curtain 22 between the feed roller A 21 and the reversing roller A 23 is the web curtain A 222. The web curtain A 222 is horizontally distributed. This design allows the cotton web to maintain a relatively stable conveying state when entering this area. Furthermore, the web curtain A 222 is used to intersect with the third web curtain, and the two work together to clamp the cotton web and drive it to move.
[0040] The first mesh curtain 22 section between the reversing roller A 23 and the discharge roller assembly A is mesh curtain B 221. Mesh curtain B 221 is distributed downwardly along the running direction. This inclined design helps to change the conveying direction of the cotton web and prepare for the subsequent web laying operation. At the same time, mesh curtain B 221 is used to intersect with the second mesh curtain to realize the transfer of the cotton web between different mesh curtains.
[0041] In this embodiment, the feed roller assembly A consists of three web-forming guide rollers: feed roller A 24, abutment roller A 26, and traction roller A 25. A first web curtain 22 is sequentially wound around the abutment roller A 26, traction roller A 25, and feed roller A 24, with the abutment roller A 26 and feed roller A 24 arranged adjacent to each other. This winding arrangement causes the first web curtain 22 to bend at an acute angle between the abutment roller A 26, traction roller A 25, and feed roller A 24. When the cotton web reaches this area, it can directly reach the feed roller A 24 from the abutment roller A 26, completing the cotton web feeding operation.
[0042] Combination Figure 4 As shown, the third mesh conveying mechanism 4 is a crucial component within the mesh laying machine, ensuring stable conveying of the cotton mesh and achieving specific material feeding functions. This mechanism comprises multiple mesh-forming guide rollers, which work together to support and guide the movement of the third mesh curtain 41. One of these guide rollers is driven by a motor, which transmits power to this roller via a transmission device, thereby driving the third mesh curtain 41 along a predetermined direction, ensuring the stability and controllability of the entire conveying process.
[0043] The part of the third mesh curtain 41 that is pressed against mesh curtain A 222 is mesh curtain C 411, which together with mesh curtain A 222 clamps the cotton web. Along the running direction of the third mesh curtain 41, the web-forming guide rollers at both ends of mesh curtain C 411 are the feed roller B 42 and the discharge roller assembly B, respectively. The discharge roller assembly B is arranged adjacent to the reversing roller A 23. This layout design allows the cotton web on mesh curtain A 222 to smoothly detach from the third mesh curtain 41 after passing through the discharge roller assembly B.
[0044] The feed roller assembly B specifically consists of three web-forming guide rollers: feed roller B 43, abutment roller B 44, and traction roller B 45. A third web curtain 41 is sequentially wound around the abutment roller B 44, traction roller B 45, and feed roller B 43, with the abutment roller B 44 and feed roller B 43 arranged adjacent to each other. This winding method causes the third web curtain 41 to bend at an acute angle between the abutment roller B 44, traction roller B 45, and feed roller B 43. When the cotton web passes through this area, it can be directly conveyed from the abutment roller B 44 to the feed roller B 43 and fall through the gap between the reversing roller A 23 and the feed roller B 43.
[0045] Combination Figure 5 As shown, the second mesh conveying mechanism 3 plays a crucial role in the mesh laying machine by receiving and conveying the cotton mesh, thus assisting in the completion of the mesh laying operation. This mechanism includes multiple mesh-forming guide rollers arranged in an orderly manner to provide support and guidance for the stable operation of the second mesh curtain 31, enabling it to move along a predetermined path. One of these guide rollers is driven by a motor, which transmits power to this roller through a transmission device, thereby driving the second mesh curtain 31 to move in a predetermined direction, ensuring the stability and controllability of the entire conveying process.
[0046] The part of the second mesh curtain 31 that is pressed against the mesh curtain B 221 is the mesh curtain D 311. The mesh curtain D 311 and the mesh curtain B 221 work closely together to clamp and convey the cotton web. Along the running direction of the second mesh curtain 31, the web-forming guide rollers at both ends of the mesh curtain D 311 are the guide roller 33 and the reversing roller B 32, respectively. The guide roller 33 guides the cotton web into the mesh curtain D 311, while the reversing roller B 32 is responsible for changing the running direction of the second mesh curtain 31.
[0047] The reversing roller B 32 is arranged adjacent to the dropping roller assembly A. This arrangement allows the cotton web on the screen B 221 to fall smoothly through the gap between the reversing roller B 32 and the dropping roller A 24 and enter the subsequent web laying stage.
[0048] The net laying machine provided by this utility model is a complete machine with a control system, power supply system, air supply system, vacuum system, etc., and realizes orderly and coordinated operation of each link through a unified interface and operation instructions.
[0049] The web-laying machine provided by this utility model features a third mesh curtain 41 that tightly engages with the first mesh curtain 22 when the cotton web enters the equipment from the feed inlet, firmly clamping the cotton web. This clamping mechanism provides strong support and constraint for the cotton web during high-speed operation, effectively solving the problem of cotton web swaying during high-speed operation. Then, with the cooperation of the first mesh curtain conveying mechanism 2, the second mesh curtain conveying mechanism 3, and the third mesh curtain conveying mechanism 4, the cotton web enters the web-laying mechanism 1 in an orderly manner for web-laying operations. Simultaneously, a speed-regulating roller 5 is added inside the web-laying machine to improve the web-laying quality. The equipment PLC performs orderly traction and stretching operations on localized areas of the cotton web through pre-set precise time parameters. After this treatment, when the cotton web enters the web-laying mechanism for laying, the thickness at the bends on both sides can be basically consistent with the thickness in the middle, greatly improving the weight uniformity of the product after web-laying, reducing quality problems caused by uneven cotton web thickness, and meeting the production requirements for product consistency and high quality.
