Description

Technical Field

[0001] The present application relates to the field of textile processing, and particularly to a fiber needle with a liquid spraying function. Background Art

[0002] In the process of textile processing, the needle is an important tool. Its main function is to repeatedly puncture the fibers in the fiber web to entangle and fix them. However, the traditional needle only has this single function and cannot meet more diverse processing requirements. With the development of the textile industry, the requirements for improving product quality, saving resources, and protecting the environment are also getting higher and higher.

[0003] In related technologies, the commonly used needles in the market currently are the same as those used in the textile industry standards, which are barbed needles. Their main function is to repeatedly puncture the fibers in the fiber web to entangle and fix them, without any other additional functions. In actual applications, sometimes it is necessary to add certain functional liquids, such as softeners and sizing agents, to the preform during the puncture process to improve the quality of the preform. However, the traditional needles cannot achieve this function, and usually, additional spraying equipment is required to spray these functional liquids.

[0004] In view of the above-mentioned related technologies, by using additional spraying equipment, certain functional liquids can be added to the preform. This method is not only cumbersome to operate, but also has low liquid utilization rate, and is prone to waste and environmental pollution. Summary of the Utility Model

[0005] In order to improve the problems of waste and environmental pollution, the present application provides a fiber needle with a liquid spraying function.

[0006] The fiber needle with a liquid spraying function provided by the present application adopts the following technical solution:

[0007] A fiber needle with a liquid spraying function includes a body. The body includes a middle part, a working part, and a needle tip. The middle part is connected to the needle plate of the needle punching machine. The middle part is provided with a first injection cavity for the flow of functional liquid. The working part is located on the side of the middle part away from the needle plate of the needle punching machine. The working part includes an insertion rod. One end of the insertion rod is connected to the middle part, and the other end is integrally provided with the needle tip. A second injection cavity is formed in the insertion rod. The first injection cavity and the second injection cavity are communicated. During the needle punching process, the functional liquid enters the fiber fabric through the second injection cavity.

[0008] By adopting the above technical solution, when needling is required, first, take out the fiber needle with liquid spraying function, connect the middle part of the needle to the needle plate on the needling machine. Subsequently, start the needling machine. The fiber needle with liquid spraying function can puncture the fiber. At the same time, inject the functional liquid into the first injection cavity. The functional liquid located in the first injection cavity can flow from the first injection cavity to the second injection cavity. During the puncture process, the functional liquid can enter the fiber through the second injection cavity. Compared with the related art, in this application, the functional liquid is injected into the first injection cavity, flows from the first injection cavity into the second injection cavity, and then directly injects the liquid into the fiber fabric without using spraying, which can make the most of the functional liquid, is not prone to waste and air pollution caused by atomization, can make the functional liquid better enter the fiber, realizes the synchronization of liquid injection and needling, has simple operation, and is beneficial to improving the problems of waste and environmental pollution.

[0009] Optionally, a plurality of injection holes are formed in the outer wall of the insertion rod, and the plurality of injection holes are evenly distributed along the circumferential direction of the insertion rod. The injection holes are communicated with the second injection cavity.

[0010] By adopting the above technical solution, during the needling process, the functional liquid located in the second injection cavity is sprayed into the fiber through the injection holes. By arranging the injection holes, it is beneficial for the functional liquid to be evenly ejected, increases the lubricity between the needle and the fiber, reduces the number of broken needles, and thus can better perform the needling operation.

[0011] Optionally, the working part further includes a plurality of protrusions, and the plurality of protrusions are evenly distributed along the outer wall of the insertion rod. The protrusions are inclined, and the protrusions are inclined away from the insertion rod from the middle part to the insertion rod. The protrusions are in the shape of barbs, and the protrusions are integrally formed with the insertion rod.

[0012] By adopting the above technical solution, during the needling process, the protrusions can grab the fiber for puncture, and the barbs can better grab the fiber, enhance the knotting effect of the non-woven material, and improve the mechanical properties of the material.

[0013] Optionally, the side of the insertion rod close to the side of the protrusion away from the middle part is inclined, and the inclined surface of the insertion rod is inclined towards the axis of the insertion rod from the tip end to the protrusion. The insertion rod and the protrusions form a receiving area for accommodating the fiber.

[0014] By adopting the above technical solution, by setting the side of the insertion rod close to the side of the protrusion away from the middle part to be inclined, the receiving area is increased.

By setting the injection hole on the inclined surface of the insertion rod, it is convenient to increase the lubricity between the acupuncture needle and the fiber.

[0017] Optionally, the first injection cavity is larger than the second injection cavity.

[0018] By adopting the above technical solution, when the functional liquid flows from the first injection cavity to the second injection cavity, the flow rate of the functional liquid increases, and the pressure in the first injection cavity is greater than the pressure in the second injection cavity, which is convenient for the functional liquid to flow from the middle part to the insertion rod.

[0019] Optionally, the insertion rod is preferably a diamond-shaped rod.

[0022] By adopting the above technical solution, during the acupuncture process, the external pump is started. The external pump pumps the functional liquid to the injection pipe. Subsequently, the functional liquid enters the first injection cavity through the injection pipe, and then enters the second injection cavity. After that, the functional liquid located in the second injection cavity is sprayed into the fiber through the injection hole. By setting the injection assembly, it is convenient to inject the functional liquid.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Compared with the related technology, in the present application, the functional liquid is injected into the first injection cavity.

The operation is simple, which is beneficial to improving the problems of waste and environmental pollution.

[0025] 2. By setting injection holes, it is beneficial for the functional liquid to be ejected evenly, increasing the lubricity between the needle and the fiber, reducing the number of broken needles, and thus enabling better needle punching operation;

Detailed Description of the Embodiment

[0031] The following is a further detailed description of this application in conjunction with the attached Figures 1-3 drawings.

[0032] The embodiment of this application discloses a fiber needle with a liquid spraying function. Refer to Figure 1 , a fiber needle with a liquid spraying function includes a body 1 and an injection assembly 2. The injection assembly 2 is arranged on the body 1, and the material of the body 1 uses a conventional metal material.

[0033] Refer to Figure 1 , the body 1 includes a needle handle 11, a middle part 12, a working part 13 and a needle tip 14. The needle handle 11 is fixedly connected to the upper needle plate of the needle punching machine by screws. The middle part 12 is located at one end of the needle handle 11. The middle part 12 can be a connecting rod or a containing box. In this embodiment, the middle part 12 is preferably a connecting rod. The middle part 12 is integrally arranged with the needle handle 11, and the middle part 12 is perpendicular to the needle handle 11 and is vertically arranged, and the middle part 12 is arranged away from the upper needle plate of the needle punching machine.

[0034] Refer to Figure 1, the working part 13 is located at one end of the middle part 12 away from the needle handle 11. In this embodiment, the working part 13 includes an insertion rod 131 and a plurality of protrusions 132. At one end of the middle part 12 away from the needle handle 11, there is a connecting cylinder 121. In this embodiment, the connecting cylinder 121 is frustum-shaped, and the larger end of the connecting cylinder 121 is integrally provided with the middle part 12. The insertion rod 131 is located at the smaller end of the connecting cylinder 121. The insertion rod 131 can be a circular rod or a diamond-shaped rod. In this embodiment, the insertion rod 131 is a diamond-shaped rod, which has the following advantages: the special design of the diamond-shaped rod needle can reduce the damage to fibers during the needling process, avoid fiber breakage, and maintain the integrity of the fibers and the strength of the non-woven material; when needling the non-woven material, its unique structure can better grasp and fix the fibers, thereby improving the reinforcement effect of the material and making the structure of the non-woven material more stable; it is applicable not only to non-woven materials composed of single fibers, but also to materials with complex structures such as woven fabrics with warp and weft interwoven, and has wide applicability; the high-efficiency needling ability of the diamond-shaped rod needle can improve the production efficiency of non-woven materials, reduce the downtime and material waste during the production process, and reduce the production cost.

[0035] Refer to Figure 1 and Figure 2 , the length direction of the insertion rod 131 is consistent with the axis direction of the connecting cylinder 121. One end of the insertion rod 131 is integrally provided with the connecting cylinder 121. The middle part 12 is provided with a first injection cavity 122, and the first injection cavity 122 is communicated with the inside of the connecting cylinder 121. The functional liquid enters the connecting cylinder 121 through the first injection cavity 122. A second injection cavity 1311 is provided in the insertion rod 131. The second injection cavity 1311 is arranged along the length direction of the insertion rod 131. The second injection cavity 1311 is for the flow of the functional liquid. The second injection cavity 1311 runs through the insertion rod 131 along the length direction of the insertion rod 131. The first injection cavity 122 is larger than the second injection cavity 1311. When the functional liquid flows from the first injection cavity 122 to the second injection cavity 1311, the flow rate of the functional liquid increases, and the pressure in the first injection cavity 122 is greater than the pressure in the second injection cavity 1311, which is convenient for the functional liquid to flow from the middle part 12 to the insertion rod 131. In this embodiment, the functional liquid is selected such as softener, sizing agent, etc. The functional liquid can increase the lubricity between the needle and the fibers and reduce the number of broken needles.

[0036] Refer to Figure 1 and Figure 2, multiple protrusions 132 are all located on the outer wall of the insertion rod 131. The combination of the insertion rod 131 and the multiple protrusions 132 can drive the fibers during the needling process, reducing the degree of twisting and curling of the punctured fibers. The multiple protrusions 132 can be one group, two groups, three groups, or multiple groups. The specific situation depends on the needs of the personnel. In this embodiment, the multiple protrusions 132 are divided into three groups, and the three groups of protrusions 132 are evenly spaced along the length direction of the insertion rod 131. The number of protrusions 132 in each group can be one, two, or multiple. In this embodiment, the number of protrusions 132 in each group is four, and the four protrusions 132 in each group are evenly distributed along the circumferential direction of the insertion rod 131. The protrusions 132 are inclined, and the protrusions 132 are inclined away from the insertion rod 131 from the connecting cylinder 121 to the insertion rod 131, making the protrusions 132 form a barbed shape. These barbs can better grasp the fibers, enhance the barbed knotting effect of the non-woven material, and improve the mechanical properties of the material. The protrusions 132 and the insertion rod 131 are integrally arranged.

[0037] Refer to Figure 1 , Figure 2 and Figure 3 , the insertion rod 131 and the protrusions 132 form a receiving area for accommodating the fibers. The side of the insertion rod 131 close to the protrusions 132 and away from the connecting cylinder 121 is set to be inclined, and the inclined surface of the insertion rod 131 is inclined towards the axis of the insertion rod 131 from the end of the insertion rod 131 away from the connecting cylinder 121 to the protrusions 132, increasing the receiving area, facilitating the grasping of the fibers, and better performing the puncture. A plurality of injection holes 1312 are provided on the side of the insertion rod 131 close to the protrusions 132 and away from the connecting cylinder 121. The injection holes 1312 are located on the inclined surface of the insertion rod 131. The injection holes 1312 correspond to the protrusions 132 one by one, and the injection holes 1312 communicate with the second injection cavity 1311. The axis of the injection holes 1312 is inclined, and the axis of the injection holes 1312 is inclined away from the axis of the insertion rod 131 from the insertion rod 131 to the protrusions 132. During the needling process, the fibers are located in the flow area, and the functional liquid located in the second injection cavity 1311 can be sprayed into the fiber fabric through the injection holes 1312.

[0038] Refer to Figure 1 and Figure 2 , the needle tip 14 is located at the end of the insertion rod 131 away from the connecting cylinder 121, and the needle tip 14 and the insertion rod 131 are integrally arranged. When needling, the needle tip 14 drives the insertion rod 131 to insert into the fibers, facilitating the puncture of the fibers.

[0039] Refer to Figure 1 and Figure 2, the injection component 2 includes an injection tube 21. The middle part 12 is provided with an injection hole 123, and the injection hole 123 communicates with the first injection cavity 122. One end of the injection tube 21 passes through the injection hole 123, and the other end is connected to an external pump. The injection tube 21 is welded to the middle part 12. When acupuncture is performed, the functional liquid can enter the first injection cavity 122 through the external pump and the injection tube 21. Subsequently, the functional liquid enters the second injection cavity 1311 from the first injection cavity 122, and then sprays from the injection hole 1312 into the fiber, realizing the synchronous progress of liquid injection and acupuncture.

[0040] The implementation principle of a fiber acupuncture needle with a liquid spraying function is as follows: When acupuncture is required, first, take out the fiber acupuncture needle with a liquid spraying function, connect the acupuncture needle to the needle disc on the acupuncture machine, and then connect the injection tube 21 in the injection component 2 to an external pump to facilitate the flow of the functional liquid. Subsequently, start the acupuncture machine. The fiber acupuncture needle with a liquid spraying function can puncture the fiber. At the same time, the external pump pumps the functional liquid from the injection tube 21 to the first injection cavity 122 of the middle part 12. The functional liquid enters the second injection cavity 1311 from the first injection cavity 122. After that, during the process of the fiber acupuncture needle with a liquid spraying function puncturing, the functional liquid sprays from the injection hole 1312 into the fiber fabric, realizing the synchronous progress of liquid injection and acupuncture until the acupuncture operation is completed.

[0041] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
