Description

Technical Field

[0001] This utility model belongs to the field of composite device technology, and in particular relates to a conveying structure for a nonwoven composite device. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, is a fabric made without traditional textile processes, through fiber combing, bonding, or needle punching. It is characterized by its lightweight, breathable, waterproof, and low-cost properties, and is widely used in masks, packaging, medical consumables, and household goods. Non-woven fabric composite devices are specialized equipment that bond single or multiple layers of non-woven fabric with other non-woven fabrics, films, fleece, and other materials. Its core function is to use processes such as pressing, hot melting, and gluing to create composite products with more comprehensive functions from materials with different properties.

[0003] However, in the existing conveying structure, the fixed roller may reverse under the tension fluctuations of the nonwoven fabric conveying, motor start-stop, or external interference. This causes the nonwoven fabric to back up and stack, which not only disrupts the consistency of the conveying direction, but also affects the precise docking of subsequent lamination processes, ultimately leading to quality defects such as product misalignment and weak lamination, while also reducing overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a conveying structure for a nonwoven fabric composite device. By setting an anti-reverse rotation part, the problem of the fixed roller reversing under the tension fluctuation of the nonwoven fabric conveying, motor start-stop, or external interference during the use of the existing conveying structure is solved. This causes the nonwoven fabric to back up and stack, which not only destroys the consistency of the conveying direction, but also affects the accurate docking of subsequent composite processes, ultimately leading to quality defects such as product misalignment and weak composite, and also reduces the overall production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a conveying structure for a nonwoven fabric composite device, comprising two fixed plates and a perforated composite device disposed between the two fixed plates, and further comprising: an anti-reverse rotation part disposed on the fixed plates; a pulling part disposed on the fixed plates; the anti-reverse rotation part comprising a rotating assembly disposed on the fixed plates; and a limiting assembly comprising a plurality of limiting assemblies, each of which is mounted on the rotating assembly; the rotating assembly comprising a rotating shaft rotatably connected between the two fixed plates, the left side of the rotating shaft penetrating the left fixed plate, a fixed roller fixedly connected to the outer wall of the rotating shaft, a fixed disc fixedly connected to the outer wall of the rotating shaft, a limiting member disposed on the left fixed plate, the fixed disc being fixed to the extended portion of the rotating shaft, the limiting member comprising a limiting ring fixedly connected to the left side of the left fixed plate, the limiting block being adapted to the limiting ring, and the limiting block extending into a limiting groove within the limiting ring.

[0007] Furthermore, the pulling part includes a fixing component disposed on a fixing plate; and a lifting component mounted on the fixing component, the lifting component being located on the right side of the fixing component.

[0008] Furthermore, the limiting component includes a rotating shaft rotatably connected to the inner wall of the fixed disk, a limiting block fixedly connected to the outer wall of the rotating shaft, and a worm spring fixedly connected to the outer wall of the rotating shaft, with the end of the worm spring fixedly connected to the inner wall of the fixed disk.

[0009] Furthermore, the fixing assembly includes a fixing rod fixedly connected to one side of two fixing plates that are close to each other. A driving component is provided on the left fixing plate. A second rotating shaft is rotatably connected between the two fixing plates. Slider blocks are slidably connected to the inner walls of both fixing rods. A third rotating shaft is fixedly connected to one side of the two sliders that are close to each other. Pressure rollers are fixedly connected to both the second and third rotating shafts. The two pressure rollers are in contact with each other. The two fixing rods are arranged in a mirror image. The driving component includes a motor bracket fixedly connected to the left side of the left fixing plate. A motor is fixedly connected to the inner wall of the motor bracket. The output shaft of the motor is fixedly connected to the second rotating shaft via a coupling. The motor is fixed to the fixing plate via the motor bracket.

[0010] Furthermore, the lifting assembly includes a threaded rod threadedly connected to a fixed rod on the right side. The top of the threaded rod extends into the fixed rod, and a connecting plate is fixedly connected to the top of the threaded rod. A telescopic rod is fixedly connected to the top of the connecting plate. The top of the telescopic rod is fixedly connected to a slider on the right side. An elastic element is provided on the telescopic rod. The connecting plate is adapted to the fixed rod. The elastic element includes a spring sleeved on the telescopic rod. The top of the spring is fixedly connected to the slider on the right side, and the bottom of the spring is fixedly connected to the connecting plate. During adjustment, the spring is in a compressed state.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting an anti-reverse rotation mechanism, after adjustment, the motor on the motor bracket starts, driving the second rotating shaft and the pressure roller on the outer wall to rotate. When the pressure roller rotates, it feeds the nonwoven fabric to the rear and pulls the fixed roller to rotate synchronously. The rotation of the fixed roller drives the first rotating shaft and the fixed plate to rotate. During the rotation of the fixed plate, the limit block is restricted and drives the rotating shaft to rotate, so that the worm spring is subjected to expansion force. The limit block is always stuck on the limit ring. At the same time, when the first rotating shaft has a tendency to reverse, the cooperation between the limit block and the limit ring forms a reverse limit, which effectively restricts the reversal of the fixed roller and avoids problems such as backing and wrinkling caused by the reversal of the fixed roller during the nonwoven fabric conveying process. This ensures the stability of the nonwoven fabric conveying direction and the continuity of the conveying process.

[0013] 2. By setting up a tensioning section, the end of the nonwoven fabric on the fixed roller is inserted between the two pressure rollers. The squeezing pressure of the two rollers is adjusted according to the material requirements of the nonwoven fabric. Rotating the threaded rod drives the connecting plate to move upward or downward. When the connecting plate moves upward, it compresses the spring, increasing the spring's thrust on the slider, thereby increasing the squeezing pressure between the two pressure rollers. When the connecting plate moves downward, the spring's squeezing force decreases, and the squeezing pressure of the two pressure rollers decreases accordingly. This avoids damage or stretching deformation of thin or soft nonwoven fabrics due to excessive squeezing pressure, and also prevents slippage and insufficient power in conveying thick or rough nonwoven fabrics due to insufficient squeezing pressure. This broadens the applicability of the device and ensures the stability of conveying nonwoven fabrics of different materials.

[0025] Please see Figure 1-6 As shown, this utility model is a conveying structure for a nonwoven fabric composite device, including two fixed plates 111 and a perforated composite device 112 disposed between the two fixed plates 111.

A fixed roller 212 is fixedly connected to the outer wall of the rotating shaft 211, and a fixed disc 213 is fixedly connected to the outer wall of the rotating shaft 211. A limiting member is provided on the left fixed plate 111, and the fixed disc 213 is fixed to the extended portion of the rotating shaft 211. The limiting member includes a fixed roller 212 fixedly connected to the left fixed plate 111. The limiting ring 214 on the left side of plate 111 is matched with the limiting block 222. The limiting block 222 extends into the limiting groove inside the limiting ring 214. The limiting component 22 includes a rotating shaft 221 rotatably connected to the inner wall of the fixed disk 213. The limiting block 222 is fixedly connected to the outer wall of the rotating shaft 221. A worm spring 223 is fixedly connected to the outer wall of the rotating shaft 221. The end of the worm spring 223 is fixedly connected to the inner wall of the fixed disk 213. By setting the anti-reverse part 2, the reverse reversal of the fixed roller 212 is effectively limited, avoiding problems such as backlash and wrinkles caused by the reverse reversal of the fixed roller 212 during the nonwoven fabric conveying process, and ensuring the stability of the nonwoven fabric conveying direction and the continuity of the conveying process.

[0027] The pulling part 3 includes a fixing component 31, which is mounted on the fixing plate 111; and a lifting component 32, which is mounted on the fixing component 31 and located on the right side of the fixing component 31. The fixing component 31 includes fixing rods 311 fixedly connected to the two fixing plates 111 on their adjacent sides. A driving component is provided on the left fixing plate 111. A rotating shaft 314 is rotatably connected between the two fixing plates 111. Sliding blocks 315 are slidably connected to the inner walls of both fixing rods 311. A rotating shaft 316 is fixedly connected to one side of the sliders 315 that are close to each other. A pressure roller 317 is fixedly connected to both the rotating shaft 314 and the rotating shaft 316. The two pressure rollers 317 are in contact with each other. Two fixed rods 311 are arranged in a mirror image. The driving component includes a motor bracket 312 fixedly connected to the left side of the left fixed plate 111. A motor 313 is fixedly connected to the inner wall of the motor bracket 312. The output shaft of the motor 313 is fixedly connected to the rotating shaft 314 via a coupling. The motor 313 is fixed to the fixed plate 111 via the motor bracket 312. On the fixed plate 111, the lifting assembly 32 includes a threaded rod 321 threadedly connected to the right-side fixed rod 311. The top of the threaded rod 321 extends into the fixed rod 311.

When adjusting, the spring 324 is in a compressed state. By setting the pulling part 3, the damage and stretching deformation of thin or soft non-woven fabrics caused by excessive extrusion pressure are avoided. It also prevents the slippage and insufficient power of conveying thick or rough non-woven fabrics caused by insufficient extrusion pressure. This broadens the application range of the device and ensures the stability of conveying non-woven fabrics of different materials.

[0028] Perforation and Composite Device 112: Develop a satellite-type perforation equipment structure, using multiple sets of different needle types such as perforating rollers, needle rollers, and rubber rollers. The final product has a hole diameter of 2.5-3 μm. The principle is that multiple sets of needle rollers surround the perforating roller, and the needle rollers mesh with the perforating roller. Temperature control is required for both the needle rollers and the perforating roller. The principle of forming holes through the piercing of the nonwoven fabric is achieved by needle roller one piercing the perforating roller, needle roller two piercing the perforating roller, and needle roller three piercing the perforating roller. After multiple piercings of the nonwoven fabric, large holes are formed. A composite structure is added, with composite points designed at needle roller three. Then, an ultrasonic or thermal composite roller meshes with needle roller three, achieving composite conditions without affecting the original pattern. It also supports thermal and ultrasonic composite processes.

[0029] It should be noted that the control of the punching composite device 112 and the motor 313 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0030] One specific application of this embodiment is as follows: In use, the end of the nonwoven fabric on the fixed roller 212 is passed between the two pressure rollers 317. At this time, the squeezing pressure between the two pressure rollers 317 can be adjusted according to the material of the nonwoven fabric. During adjustment, the threaded rod 321 is rotated. When rotating, the threaded rod 321 will move the connecting plate 322 upward or downward. When the connecting plate 322 moves upward, it will squeeze the spring 324. At this time, the spring 324 will exert a greater pushing force on the slider 315, and thus the squeezing pressure between the two pressure rollers 317 will be greater. The opposite is true when moving downward. In this way, it can be adapted to nonwoven fabrics of various materials. After the adjustment is completed, the motor 313 on the motor bracket 312 is started. The rotating shaft 314 will rotate along with the pressure roller 317 on its outer wall. During rotation, it will convey the nonwoven fabric to the rear. When the pressure roller 317 moves the nonwoven fabric, the fixed roller 212 will rotate accordingly. When the fixed roller 212 rotates, the rotating shaft 211 will also rotate along with the fixed disk 213. When the fixed disk 213 rotates, the limiting block 222 will be restricted, thus causing the rotating shaft 221 to rotate accordingly. As the rotating shaft 221 rotates, the worm spring 223 will be subjected to a certain expansion force. With the movement of the limiting block 222, it will always be stuck on the limiting ring 214. When the rotating shaft 211 reverses, it will also be limited by the combination of the limiting block 222 and the limiting ring 214. Thus, the effect of restricting the rotating shaft 211 and the fixed roller 212 from reversing can be achieved.
