Description

Technical Field

[0001] The utility model belongs to the technical field of supporting facilities for a non-woven product production line, and specifically relates to a non-woven fiber oiling device arranged between an opener and a cotton outlet fan. Background Art

[0002] The non-woven product production line mentioned above refers to the equipment configured in the whole process of converting the fibers in the packaged state to non-woven products such as non-woven fabrics and non-woven felts. Simply speaking, it is an industrial production model. Specifically, the fibers in the packaged state are unpacked by the package opener, and then introduced into the opener for opening. The fibers opened by the opener are sent to the carding machine through the conveyor curtain, and then laid on the net machine, and then needled or hydroentangled by the needle punching machine or hydroentanglement machine to obtain the aforementioned non-woven fabric or similar products such as non-woven felts.

[0003] The aforementioned oil is an oil agent, and the oil agent is essentially a preparation with corresponding functions such as antistatic, flame retardant, and lubricant, such as an antistatic agent, a flame retardant, and a lubricant. The reason why the fibers opened by the opener are oiled (i.e., sprayed with oil agents) is to enhance the function and combability of the fibers. Taking antistatic agents as an example, because static electricity can interfere with the production process and even cause safety accidents, the main mechanisms of action of antistatic agents are: forming a conductive channel so that the charge can be quickly removed (migrated) from the fiber surface; forming hydrates by absorbing water and dissociating into ions, thereby enhancing the conductive effect. It can also be understood that the antistatic agent reduces the surface resistance of the fiber, absorbs moisture in the atmosphere on the fiber surface to form a tiny conductive film, thereby quickly eliminating static electricity. Antistatic agents can also significantly increase the lubrication of the fiber, which is beneficial for mixed combing, etc. Since the aforementioned antistatic agent belongs to the scope of known technology, the applicant will not elaborate on it.

[0004] Previously, fibers opened by an opener were usually transported to a carding machine by a conveyor curtain, and an oil spraying device was set with a conveyor curtain frame as a carrier at a reasonable position corresponding to the area of the conveyor curtain. The disadvantage of this oil spraying method is that the fibers located on the surface of the conveyor curtain can obtain the oil, while the fibers at the lower part are difficult or even unable to obtain the desired oil, resulting in a yin-yang situation and not conducive to the carding of the carding machine.

[0005] With the application of the cotton discharge fan, the aforementioned oil spray device arranged on the conveying curtain is abandoned, that is, the fibers opened by the opener are led to the cotton box through the cotton discharge port of the cotton discharge fan through the pipeline and then to the combing machine for combing.

[0006] In the publicly available Chinese patent documents, technical information on oiling the fibers opened by an opener (taking the spraying of "antistatic agent" as an example, the same hereinafter) can be seen. Typically, such as the "Automatic Spraying Device for Opener Oil Agent" recommended by CN203625549U. According to the description in paragraph 0017 of the specification of this patent, it first sprays oil on the waste materials or scraps entering the opener body from the feed inlet before they enter the opening rollers. After spraying, the waste materials or scraps leave the opener body for the opening rollers to open. Although this patent has the advantages described in its specification, since the oil agent is sprayed on the surface before the materials enter the opening rollers, the interior of the waste materials or scraps cannot obtain the desired oil agent. Even after being opened by the subsequent opening rollers, the oil agent on the opened fibers is extremely uneven. Therefore, spraying the oil agent first and then opening is not an ideal approach. Another example is the "Spraying Device for Uniformly Mixed Antistatic Agent" provided by CN216688642U. According to paragraph 0031 of the specification of this patent: While the fibers opened by the opener are introduced into the first container, the first nozzle sprays the antistatic agent onto the fibers introduced into the first container at the same time, and the second nozzle sprays the antistatic agent onto the fibers introduced from the first container into the second container, so that the antistatic agent further penetrates into the fibers. Among them, this patent also specifically teaches: "After enough fibers are accumulated in the first container, the fibers are extracted into the second container by a blower." It can be seen from this that although this patent can meet the requirement of synchronously carrying out opening and spraying the antistatic agent, since it is necessary to wait until enough fibers are accumulated in the first container and then be drawn into the second container by the cotton output blower and the second nozzle sprays oil on the fibers in the second container, to a certain extent, the fibers during the oil spraying process are basically static. So on the one hand, it is not sufficient for all surfaces of the fibers to be fully oiled and penetrate into the fibers, and on the other hand, the consumption of the oil agent is relatively large, which is not conducive to saving the relatively expensive oil agent. Summary of the Invention

[0007] The object of the present invention is to provide a non-woven fiber oiling device arranged between an opener and a cotton output blower, which helps to spray the oil agent on the fibers opened by the opener in a good dynamic diffusion state so that all surfaces of the fibers are evenly oiled.

[0029] Continue to see Figure 1 , the aforesaid oil spraying mechanism 3 includes an oil spray nozzle fixing bracket 31, an oil spray nozzle 32 and an oil introducing pipe 33. The oil spray nozzle fixing bracket 31 is fixed to the aforesaid loosened fiber guiding shell tube 1 at the middle position in the height direction corresponding to the aforesaid shell tube socket 16b. The oil spray nozzle 32 is fixed on the oil spray nozzle fixing bracket 31 and the spray head 321 of the oil spray nozzle 32 extends into the aforesaid pipe cavity 11. One end of the oil introducing pipe 33 is connected to the oil spray nozzle 32, and the other end of the oil introducing pipe 33 is connected to the oil outlet of an oil supply pump.

[0030] The aforementioned oil spraying control mechanism 4 includes an air pressure regulating valve 41, an air supply pipe 42, a support plate 43, a filter 44, an electromagnetic control valve 45, a transition air pipe 46 and an air outlet pipe 47. The air pressure regulating valve 41 is arranged on the upper part of one end of the aforementioned frustum 21 facing the aforementioned oiled fiber outlet interface 13 and is communicated with the filter 44. One end of the air supply pipe 42 is connected to the air pressure regulating valve 41, and the other end of the air supply pipe 42 is connected to a pressure air production source. The support plate 43 is fixed on the upper part of one end of the aforementioned frustum 21 facing the oiled fiber outlet interface 13.

[0031] In this embodiment, the aforementioned pressure air production source is an air compressor, but an air pump or other similar devices can also be used.

[0032] From Figure 1 As can be seen from the schematic diagram, the overall shape of the aforementioned loosened fiber guiding shell tube 1 is generally L-shaped. The reason for saying generally L-shaped is that a first fiber arc-shaped diffusion wall 14 is formed on the front side of the right end, and a second fiber arc-shaped diffusion wall 15 is formed at the folded part of the L-shaped, that is, the left end. The cross-sectional shape of the aforementioned loosened fiber guiding shell tube 1 is rectangular, that is to say, a rectangular tube is used as the loosened fiber guiding shell tube 1.

[0033] Please refer to Figure 2 And in combination with Figure 1 The non-woven fibers loosened by the opener 5 sequentially enter the lumen 11 of the loosened fiber guiding shell tube 1 through the opener outlet pipe 51 and the loosened fiber inlet interface 12. And under the operation of the outlet air blower 6, the fibers are then sequentially led to the cotton box and then to the carding machine for carding through the oiled fiber outlet interface 13, the oiled fiber outlet cover 2, the outlet air blower inlet pipe 61 and the outlet air blower outlet pipe 62. In the aforementioned process, with the operation of the opener 5, the electrical controller gives a working instruction to the electromagnetic control valve 45. As the electromagnetic control valve 45 enters the working state (i.e., the "open state"), the aforementioned oil supply pump also receives the working instruction from the electrical controller accordingly and pumps oil from the oil storage tank. The oil agent is led to the oil spray nozzle 32 through the oil agent inlet pipe 33, and the spray head 321 of the oil spray nozzle 32 sprays oil on the fibers in the floating and diffusing state in the lumen 11. The oil-gas ratio and its pressure can be achieved by adjusting the air pressure regulating valve 41. Since the fibers can obtain a good diffusion effect when passing through the first and second fiber arc-shaped diffusion walls 14 and 15, all surfaces of the fibers can well obtain the oil agent sprayed by the spray head 321, providing good conditions for the carding of the subsequent carding machine.

[0034] In summary, the technical solution provided by the present utility model makes up for the deficiencies in the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the technical effect column above.
