Description

Technical Field

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

[0002] In modern industrial production, non-woven fabrics are widely used in many fields such as medical and health care, packaging, and agriculture due to their excellent properties such as light weight, moisture resistance, and breathability. As the demand for non-woven fabrics continues to rise, the performance of non-woven fabric unwinding devices, as key equipment in the subsequent processing and production of non-woven fabrics, directly affects production efficiency and product quality.

[0003] Existing nonwoven fabric unwinding devices have many problems in the installation and disassembly of nonwoven fabric rolls. For nonwoven fabric rolls of different specifications, the existing unwinding devices have poor adaptability, requiring frequent adjustment of equipment parameters or replacement of parts, resulting in low production efficiency and affecting installation and disassembly efficiency. Some unwinding devices that adopt radial installation and disassembly have unreasonable structural design, which can easily cause problems such as nonwoven fabric deviation during the unwinding process, affecting the quality of subsequent processing.

[0004] According to the description of a nonwoven fabric unwinding device published on the patent website (authorization announcement number: CN217626717U), the nonwoven fabric unwinding device includes "material rollers, tension adjustment devices, etc." to realize the unwinding operation.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This nonwoven fabric unwinding device uses material rollers and tension adjustment devices to achieve unwinding. Although this device can adjust the tension of the fabric during unwinding, it cannot easily install and remove the material rollers. If the material rollers are integrated, it is not easy to replace them when the fabric is unwound, which affects the processing efficiency. Therefore, this device needs to be improved.

[0013] Preferably, the limiting component includes a load-bearing frame, which is fixedly connected to the left side of the load-bearing platform.

[0014] Preferably, the left side of the spring is fixedly connected to the right side of the movable plate, the right side of the spring is fixedly connected to the left side of the mounting frame, and the squeezing roller is located in the middle of the left side of the mounting base, so that the squeezing roller can limit the fabric when feeding the nonwoven fabric roll.

[0015] Preferably, the support mechanism includes a second hydraulic cylinder, which is fixedly connected to the top of the base.

[0016] Preferably, the fixed shaft is fixedly connected to the rear side of the mounting base, and the fixed plate is made of alloy steel, which facilitates the support frame to support the fixed plate and further ensures the stability and balance of the mounting base during operation.

[0017] Compared with the prior art, the present invention provides a nonwoven fabric unwinding device, which has the following beneficial effects:

[0018] 1. This nonwoven fabric unwinding device, through its unwinding mechanism, allows for unwinding of nonwoven fabric rolls. First, the nonwoven fabric roll is slidably connected to the periphery of the fixed plates, with the four fixed plates in a closed state. Then, based on the inner dimensions of the nonwoven fabric roll, the adjusting disc is rotated, causing the threaded rod to rotate and move back and forth within the fixed cylinder. The movement of the threaded rod causes the mounting base to slide around the fixed cylinder, and the movement of the mounting base causes the concave frame to move. During this movement, the connecting shaft changes angle between the concave frame and the fixed plates, thus altering the distance between the four fixed plates and the mounting base. This adapts to different specifications of nonwoven fabric roll inner diameters. This ensures the nonwoven fabric roll is securely installed, and the fixed plate moves the slider inside the limit frame to guarantee the stability of the fixed plate during movement. The servo motor drives the limit frame, fixed cylinder, and other structures to rotate via the rotating shaft, realizing the automatic unwinding of the nonwoven fabric. The spring and the extrusion roller work together to adaptively adjust the extrusion pressure on the nonwoven fabric according to its thickness and material. When the thickness of the nonwoven fabric changes, the extrusion roller moves under force to compress the spring. The reverse force generated by the spring keeps the extrusion roller in appropriate contact pressure with the nonwoven fabric, which can prevent the nonwoven fabric from loosening and avoid excessive pressure that could damage the surface of the nonwoven fabric, thus achieving flexible limiting and protection of the nonwoven fabric.

[0019] 2. This nonwoven fabric unwinding device, through its supporting mechanism, allows the second hydraulic cylinder to flexibly adjust the height of the support frame according to actual production needs after the nonwoven fabric roll is fixed by the mounting base and the fixing plate. This ensures the support frame is positioned around the fixing plate, thus supporting the mounting base. When the mounting base rotates the nonwoven fabric roll, it ensures stability and balance during rotation. The fixing plate is made of alloy steel, which has high strength and high wear resistance, ensuring safety and stability during use and extending its service life. Attached Figure Description

[0032] This utility model provides the following technical solution:

[0033] Example 1

[0034] Please see Figures 1-8 This utility model provides a technical solution: a non-woven fabric unwinding device, including a base 1, a unwinding mechanism 2 provided on the top of the base 1, and a support mechanism 3 provided on the top of the base 1;

[0035] The unwinding mechanism 2 includes an unwinding component 21 and a limiting component 22. The unwinding component 21 is located on the top of the base 1, and the limiting component 22 is located on the left side of the unwinding component 21.

[0036] The unwinding assembly 21 includes a support platform 211, which is fixedly connected to the top of the base 1. A support frame 212 is fixedly connected to the front of the support platform 211. A servo motor 213 is fixedly connected to the top of the support frame 212. A rotating shaft 214 is fixedly connected to the rear of the servo motor 213. A limit frame 215 is fixedly connected to the rear of the rotating shaft 214. A fixed cylinder 216 is fixedly connected to the rear of the limit frame 215. A threaded rod 217 is internally threaded into the fixed cylinder 216. An adjusting disc 219 is fixedly connected to the rear of the threaded rod 217. A mounting base 218 is rotatably connected to the periphery of the threaded rod 217. A concave frame 2191 is fixedly connected to the periphery of the mounting base 218. A connecting shaft 2192 is rotatably connected to the inner side of the concave frame 2191. A fixing plate 2193 is rotatably connected to the top periphery of the top of the connecting shaft 2192. A slider 2194 is fixedly connected to the top front of the fixing plate 2193.

[0037] The top of the fixed plate 2193 is arc-shaped. The rotating shaft 214 is rotatably connected to the inside of the support platform 211. The mounting base 218 is slidably connected to the outside of the fixed cylinder 216. The slider 2194 is slidably connected to the inside of the limit frame 215, so that the stability of the fixed plate 2193 can be ensured when it moves up and down through the slider 2194.

[0038] The concave frame 2191, connecting shaft 2192, fixing plate 2193 and slider 2194 are provided in four sets. The four sets of concave frame 2191, connecting shaft 2192, fixing plate 2193 and slider 2194 are symmetrically distributed around the mounting base 218, which facilitates the passage of the four sets and ensures the stability when fixing the nonwoven fabric roll.

[0039] Please see Figures 1-8 The present invention provides a technical solution: the limiting component 22 includes a load-bearing frame 221, which is fixedly connected to the left side of the load-bearing platform 211. A first hydraulic cylinder 223 is fixedly connected to the left side of the load-bearing frame 221, and a moving plate 224 is fixedly connected to the right side of the first hydraulic cylinder 223. A sliding rod 222 is fixedly connected to the left side of the moving plate 224, and the sliding rod 222 is slidably connected inside the load-bearing frame 221. A limiting rod 225 is slidably connected inside the moving plate 224. A mounting frame 227 is fixedly connected to the right side of the limiting rod 225. A squeezing roller 228 is rotatably connected to the inner side of the mounting frame 227, and a spring 226 is sleeved around the limiting rod 225.

[0040] The left side of the spring 226 is fixedly connected to the right side of the movable plate 224, and the right side of the spring 226 is fixedly connected to the left side of the mounting bracket 227. The squeeze roller 228 is located in the middle of the left side of the mounting base 218, so that the squeeze roller 228 can limit the fabric when feeding the nonwoven fabric roll.

[0041] Example 2

[0042] Please see Figures 1-8 Furthermore, based on Embodiment 1, the support mechanism 3 further includes a second hydraulic cylinder 31, which is fixedly connected to the top of the base 1. A support frame 32 is fixedly connected to the top of the second hydraulic cylinder 31, and a fixed disk 33 is rotatably connected to the inner side of the support frame 32. A fixed shaft 34 is fixedly connected to the front side of the fixed disk 33.

[0043] The fixed shaft 34 is fixedly connected to the rear side of the mounting base 218. The fixed plate 33 is made of alloy steel, which facilitates the support frame 32 to support the fixed plate 33, further ensuring the stability and balance of the mounting base 218 during operation.

[0044] In actual operation, when this device is used and it is necessary to unwind the non-woven fabric roll, the non-woven fabric roll is first slidably connected to the periphery of the fixing plate 2193, and the four sets of fixing plates 2193 are in a closed state. At this time, according to the inner size of the non-woven fabric roll, the adjusting plate 219 is rotated to drive the threaded rod 217 to rotate and move back and forth in the fixing cylinder 216. When the threaded rod 217 moves, it will drive the mounting seat 218 to slide on the periphery of the fixing cylinder 216. When the mounting seat 218 moves, it will drive the concave frame 2191 to move. During the movement, the connecting shaft 2192 will change the angle between the concave frame 2191 and the fixing plate 2193, which can change the distance between the four sets of fixing plates 2193 and the mounting seat 218, which can adapt to the inner diameter of non-woven fabric rolls of different specifications, ensuring that the non-woven fabric roll is stably installed. In addition, the fixing plate 2193 will drive the slider 2194 to slide inside the limit frame 215, ensuring the stability of the fixing plate 2193 when it moves.

[0045] After fixing, the second hydraulic cylinder 31 can flexibly adjust the height of the support frame 32 according to actual production needs, so that the support frame 32 is located outside the fixed plate 33, which can support the mounting base 218.

[0046] Simultaneously, the first hydraulic cylinder 223 drives the moving plate 224 to move, which in turn drives the limiting rod 225, the mounting frame 227, and the extrusion roller 228 to move, so that the extrusion roller 228 comes into contact with the fabric. The spring 226 cooperates with the extrusion roller 228, which can adaptively adjust the extrusion pressure on the nonwoven fabric according to the thickness and material of the nonwoven fabric. When the thickness of the nonwoven fabric changes, the extrusion roller 228 is forced to move and compress the spring 226. The reverse force generated by the spring 226 keeps the extrusion roller 228 in appropriate contact pressure with the nonwoven fabric, which can prevent the nonwoven fabric from loosening and avoid excessive pressure from damaging the surface of the nonwoven fabric, thus achieving flexible limiting and protection of the nonwoven fabric.

[0047] After fixing and limiting, the servo motor 213 drives the non-woven fabric roll, which is fixedly connected to the limiting frame 215, the fixed cylinder 216, the threaded rod 217, the mounting base 218 and the fixing plate 2193, to rotate through the rotating shaft 214. The mounting base 218 drives the fixing shaft 34 and the fixing plate 33 to rotate inside the support frame 32, thereby realizing the automatic unwinding of the non-woven fabric. At the same time, it can ensure the stability of the non-woven fabric roll during rotation and facilitate the installation and disassembly of the non-woven fabric roll, improving the efficiency of replacement.

[0048] In use, the servo motor 213, the first hydraulic cylinder 223, and the second hydraulic cylinder 31 can be connected to the same PLC control system to ensure coordinated operation between the devices. Furthermore, the PLC control system is existing technology, and those skilled in the art are well aware of the specific operating steps of this system.

[0049] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
