Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a nonwoven fabric extrusion device for nonwoven fabric production. Background Technology

[0002] Nonwoven fabric is a type of fabric that does not require spinning or weaving. Instead, it is made by orienting or randomly arranging short textile fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods.

[0003] Nonwoven fabric extrusion involves feeding, melting, and extrusion. Generally, raw material mixing occurs during feeding; however, mixing in a solid state is relatively ineffective, easily leading to issues such as layering, spots, and broken fibers. Therefore, we propose a nonwoven fabric extrusion device for nonwoven fabric production. Utility Model Content

[0004] In view of this, the present invention provides a nonwoven fabric extrusion device for nonwoven fabric production, which solves the problem of uneven material extrusion in the prior art because the raw materials are only mixed in a solid state.

[0005] A nonwoven fabric extrusion device for nonwoven fabric production includes an intermediate filtration and mixing assembly installed between an extruder and an extrusion die. The intermediate filtration and mixing assembly includes a gourd-shaped spherical cylinder with a stirring shaft rotatably mounted on it via a sealed bearing. A stirring motor is fixedly mounted on one side of the spherical cylinder and is drively connected to the stirring shaft. A spherical filter cover is fixedly installed inside the spherical cylinder, with the inlet of the spherical filter cover facing the outlet of the extruder. The stirring shaft passes through the spherical filter cover and is fixedly connected to a stirring rod.

[0006] Preferably, a first gear is installed on the stirring shaft, a mounting base is fixedly connected to one side of the spherical cylinder, the stirring motor is fixedly installed on the mounting base, and a second gear is installed on the motor shaft of the stirring motor, with the first gear and the second gear meshing together.

[0007] Preferably, the bottom of the spherical cylinder is connected to a collecting cylinder, the upper end of the collecting cylinder is fixedly connected to the bottom of the spherical filter cover and communicates with the inside of the spherical filter cover, and a plug is threaded onto the lower end of the collecting cylinder.

[0008] Preferably, the stirring rod described above is configured with an arc-shaped structure, and at least one of the stirring rods is able to fit against the inner wall of the spherical filter cover.

[0009] Preferably, both ends of the aforementioned intermediate filter mixing assembly are fixedly connected to flanges, which are respectively fixedly connected to the extruder and the extrusion die.

[0010] Preferably, the surface of the spherical cylinder is fixedly connected with a sleeve.

[0011] Preferably, the surface of the spherical cylinder is covered with a heat-insulating asbestos layer.

[0012] Implementing the embodiments of this utility model will have the following beneficial effects:

[0013] The aforementioned nonwoven fabric extrusion device for nonwoven fabric production was adopted.

[0014] Adding an intermediate filtration and mixing component between the extruder and the extrusion die can further and fully mix various raw materials in the molten liquid state. After extrusion, it is less likely to cause thick and thin layering, spots, broken fibers, etc., thus improving the quality of the product.

[0015] Among them, the intermediate filtration and mixing component also has a filtration function, so that some impurities that appear in the raw materials after melting will not enter the extrusion die, thus ensuring the quality of the subsequent extruded products.

[0016] By combining the collection cylinder, the spherical filter cover, and the stirring rod, the stirring rod can pass over the inner wall of the spherical filter cover during stirring, sweeping away the impurities stuck to the inner wall of the spherical filter cover, and can concentrate most of the impurities into the collection cylinder without affecting the filtration effect of the spherical filter cover. At the same time, it also reduces the cleaning frequency of the spherical filter cover. Attached Figure Description

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figure 1-3 A nonwoven fabric extrusion device for nonwoven fabric production includes an intermediate filtration and mixing assembly 200, which is installed between an extruder 100 and an extrusion die 300. The intermediate filtration and mixing assembly 200 includes a gourd-shaped spherical cylinder 201. A stirring shaft 207 is rotatably mounted on the spherical cylinder 201 via a sealed bearing 208. A stirring motor 204 is fixedly mounted on one side of the spherical cylinder 201, and the stirring motor 204 is drively connected to the stirring shaft 207. The stirring motor 204 can simultaneously drive two stirring shafts 207 to rotate. The stirring motor 204 is equipped with a separate switch to control its start and stop.

[0030] like Figure 3 As shown, a spherical filter cover 211 is fixedly installed inside the spherical cylinder 201. The inlet of the spherical filter cover 211 is opposite to the opening of the extruder 100. The stirring shaft 207 passes through the spherical filter cover 211 and is fixedly connected to the stirring rod 210. Note that the spherical filter cover 211 has a through-hole to facilitate the passage of the stirring shaft 207.

[0031] More specifically, such as Figure 2 As shown, a first gear 206 is mounted on the stirring shaft 207, a mounting base 203 is fixedly connected to one side of the spherical cylinder 201, the stirring motor 204 is fixedly mounted on the mounting base 203, and a second gear 205 is mounted on the motor shaft of the stirring motor 204. The first gear 206 and the second gear 205 are meshed together.

[0032] In implementation, a collection cylinder 209 is connected through the bottom of the spherical cylinder 201. The upper end of the collection cylinder 209 is fixedly connected through the bottom of the spherical filter cover 211 and communicates with the interior of the spherical filter cover 211. A plug 212 is threadedly installed at the lower end of the collection cylinder 209. The plug 212 is a sealing plug that can maintain a seal. When the machine stops working, it can be opened to periodically clean the impurities inside the collection cylinder 209.

[0033] like Figure 3 In the middle, the stirring rod 210 is configured with an arc-shaped structure, and at least one of the stirring rods 210 (e.g. Figure 3 The outermost stirring rod 210 can fit against the inner wall of the spherical filter cover 211. If there are impurities on the inner wall of the spherical filter cover 211, they can be swept off.

[0034] The intermediate filter mixing component 200 has flanges 202 fixedly connected to both ends, and the flanges 202 at both ends are fixedly connected to the extruder 100 and the extrusion die 300, respectively.

[0035] In implementation, a jacket is fixedly connected to the surface of the spherical cylinder 201. The jacket allows flowing heat transfer oil to pass through and also includes a constant temperature oil tank and a hot oil pump. The constant temperature oil tank is equipped with an electric heating element, thermocouple, temperature controller, etc. (these are all existing technologies and will not be described in detail here). By heating the inside of the spherical cylinder 201 with the constant temperature hot oil, a constant temperature can be maintained, preventing the temperature of the liquid inside the spherical cylinder 201 from dropping.

[0036] In practice, an insulating asbestos layer can be wrapped around the surface of the spherical cylinder 201. This insulation helps prevent the molten material from cooling down.

[0037] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.
