Description

Technical Field

[0001] This utility model relates to nonwoven fabric production equipment, specifically providing an automatic feeder nonwoven fabric web forming machine. Background Technology

[0002] Non-woven fabric, also known as non-woven textile, is a fibrous product formed directly through physical, chemical, or mechanical means without the need for traditional spinning and weaving processes. It can be made in various thicknesses, textures, and hardnesses, and features moisture resistance, breathability, flexibility, lightness, low cost, good filtration, and recyclability. Non-woven fabrics can be used in various industries, such as medical, clothing, household goods, and industrial applications, for purposes such as sound insulation, heat insulation, and adsorption filtration.

[0003] Nonwoven fabrics are typically formed using meltblown and spunbond processes. The meltblown process requires a web-forming machine. At the web-forming machine, the randomly dispersed filaments formed by meltblowing are uniformly collected onto a receiving screen through negative pressure suction or mechanical conveying, forming a continuous fiber web, thus creating a porous and fluffy nonwoven fabric. It's understood that the receiving screen in the web-forming machine has many tiny mesh structures, which create negative pressure when suctioned from within.

[0004] The meltblown mechanism contains a large amount of raw materials in a molten state. When the production equipment is powered off, the molten raw materials are very likely to drip from the outlet of the meltblown mechanism onto the web forming machine, which can easily clog the receiving screen of the web forming machine.

[0005] Therefore, there is an urgent need for a nonwoven fabric forming machine with baffles to solve the problem that existing forming machines are easily blocked after the production equipment is powered off. Utility Model Content

[0033] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] To address the issue of existing web forming machines being easily blocked after a power outage, refer to... Figure 1 This utility model provides an automatic material-blocking nonwoven fabric forming machine, including a frame 1, a forming roller 2, and a material-blocking mechanism 3. Both the forming roller 2 and the material-blocking mechanism 3 are mounted on the frame 1. The material-blocking mechanism 3 can block the forming roller 2 to prevent debris from falling onto it and causing blockage. For example, even if molten material in the meltblown mechanism 4 drips after the production equipment stops or the power is cut off, it can be blocked by the material-blocking mechanism 3 to prevent blockage of the forming roller 2.

[0037] refer to Figure 1 and Figure 2 The forming roller 2 is horizontally positioned and rotatably connected to the frame 1. The surface of the forming roller 2 is hollowed out and covered with a receiving screen 21 on the outside. The receiving screen 21 is mesh-like and has a high mesh count. Among them, the receiving screen 21 on the forming roller 2 is a component that is relatively easy to be clogged by debris, so it needs to be protected to avoid replacement after clogging, which would increase maintenance costs.

[0038] The inside of the forming roller 2 is hollow, forming a cavity, and the rotating shaft 22 of the forming roller 2 is also hollow. The rotating shaft 22 of the forming roller 2 is connected to the air inlet of the negative pressure fan through a pipe, so that the cavity of the forming roller 2 can always maintain negative pressure.

[0039] Under normal circumstances, the meltblown mechanism 4 can spray out filamentous fibers. After passing through the web forming roller, the randomly dispersed filamentous fibers are evenly captured on the receiving screen 21 under the negative pressure of the web forming roller 2, forming a continuous fiber web, thereby forming a porous and fluffy nonwoven fabric.

[0040] In some examples, reference Figure 1 The frame 1 is equipped with a guide roller 11, which is rotatably connected to the frame 1 and is used to guide the nonwoven fabric formed by the web forming roller 2.

[0041] refer to Figure 1 and Figure 3 The material blocking mechanism 3 includes a power source, a drive assembly, a material blocking curtain 32, and a guide member 33. The drive assembly is configured to extend the material blocking curtain 32 to cover the forming roller 2, or retract it to expose the forming roller 2. The power source provides power to the drive assembly, and the guide member 33 guides the movement direction of the material blocking curtain 32. When the forming machine is not in use, the drive assembly drives the material blocking curtain 32 to extend, which can cover the forming roller 2 and prevent debris from entering the forming roller 2 and clogging the mesh on the receiving screen 21. When the forming machine is in use, the drive assembly can drive the material blocking curtain 32 to retract, exposing the forming roller 2 and ensuring that the forming roller 2 can be used normally.

[0042] To ensure the material blocking mechanism 3 continues to function properly after a power outage, allowing the material blocking curtain 32 to unfold and block the molten material temporarily stored in the meltblown mechanism 4, the power source needs to be independent of the normal power supply. For example, the power source could be compressed air, and the drive component could be a pneumatic component, such as a cylinder, using a relatively independent compressed air system to power the drive component. Alternatively, the power source could be a battery or emergency power supply, and the drive component could be an electric component, using a separate battery or emergency power supply to power the drive component.

[0043] For example, refer to Figure 3 The guide member 33 includes two members, which are parallel and opposite to each other. The opposite side of the guide member 33 has a guide groove 331. The guide members 33 are located on both sides of the baffle curtain 32 along the width direction, and the side of the baffle curtain 32 is located in the guide groove 331 and supported by the guide groove 331.

[0044] In some examples of this utility model, references Figure 1 and Figure 4 The drive assembly includes a motor and a roller 312. The motor drives the roller 312 to rotate forward or backward. One end of the baffle curtain 32 is connected to the roller 312, and the other end slides into the guide groove 331. The guide member 33 includes a straight portion 332 and a curved portion 333. The curved portion 333 is arranged around the roller 312 so that the baffle curtain 32 can easily enter the straight portion 332 along the curved portion 333. The forward or reverse rotation of the motor can drive the roller 312 to rotate forward or backward, thereby driving the baffle curtain 32 connected to the roller 312 to move along the guide member 33 to wind up or unwind, thus blocking or exposing the forming roller 2.

[0045] For example, refer to Figure 3 The baffle curtain 32 is elastic, and the material includes steel and other elastic materials, which enables the baffle curtain 32 to maintain a certain rigidity in the width direction to support the guide member 33, and can also produce elastic deformation to move along the guide member 33.

[0046] For example, refer to Figure 5 and Figure 6 The baffle curtain 32 is flexible, and the material may include flexible materials such as cloth. The baffle curtain 32 is provided with a keel 321 and elastic support strips 322. The keel 321 is arranged along the width direction of the baffle curtain 32 and is spaced apart along the length direction of the baffle curtain 32. The two ends of the keel 321 are respectively located in the guide grooves 331 of different guide members 33. The elastic support strips 322 extend along the length direction of the baffle curtain 32 and multiple strips are arranged along the width direction of the baffle curtain 32.

[0047] In other examples of this utility model, reference is made to Figure 1 and Figure 7The baffle curtain 32 is foldable along its length. One end of the baffle curtain 32 is fixed to the guide member 33, and the other end is provided with a fixing member 323. The drive assembly is used to drive the fixing member 323 to reciprocate along the length of the baffle curtain 32 to fold or extend the baffle curtain 32. The drive assembly drives the fixing member 323 to reciprocate under the guidance of the guide member 33, which can drive the baffle curtain 32 to fold or extend, thereby covering or exposing the forming roller 2.

[0048] For example, the baffle curtain 32 has ribs 321 extending along the width direction of the baffle curtain 32. The ribs 321 are spaced apart along the length direction of the baffle curtain 32. The baffle curtain 32 is fixed to the ribs 321, and both ends of the ribs 321 are located in the guide grooves 331. The ribs 321 are used to support the baffle curtain 32 to ensure that the baffle curtain 32 can be supported on the guide member 33. At the same time, as the spacing between the ribs 321 changes, the baffle curtain 32 between two adjacent ribs 321 can be folded or extended.

[0049] In summary, the working principle of the nonwoven fabric web forming machine provided by this utility model is as follows:

[0050] When the forming machine is not in use, the drive assembly drives the baffle curtain 32 to move along the guide 33 and extend it to cover the forming roller 2, preventing debris from entering the forming roller 2 and clogging the mesh on the receiving screen 21. When the forming machine is in use, the drive assembly drives the baffle curtain 32 to move along the guide 33 and retract it to expose the forming roller 2, ensuring that the forming roller 2 can be used normally. The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
