Abstract
Description
Technical Field
[0001] This utility model belongs to the field of new fiber and composite material preparation technology, specifically relating to a multi-faceted pyramidal needle for pre-oxidized fiber felt. Background Technology
[0002] Currently, pre-oxidized filament felt is made by combing pre-oxidized filament fibers into a web, then stacking multiple webs and feeding them into a needle punching machine for needle punching on both sides, followed by heat setting and cutting to complete the entire processing procedure.
[0003] The effectiveness of acupuncture is directly related to the final performance of the product. Currently used acupuncture needles basically consist of a needle handle, a needle shaft, and a needle tip. The needle shaft has barbs, which, guided by the needle tip, cause the fibers between multiple layers to interweave in a staggered manner. However, because the distribution of the barbs is very important, if the distribution of the barbs is uneven or the force applied is uneven when needling upwards, the following technical defects exist:
[0004] 1) The current barbs are all unidirectional, so during the acupuncture process, only unidirectional acupuncture can be performed, which not only results in low acupuncture efficiency, but also generally poor acupuncture quality.
[0005] 2) If the hooking force is not in the same direction as the needle, the needle breakage rate will increase significantly, and the broken needles will be embedded in the interior of the felt, which will greatly increase the difficulty of removing broken needles in the later process.
[0006] 3) The cylindrical needle bar used has a large contact area with the multi-layer mesh, and all fibers are pushed outward, resulting in high resistance. In addition, the barbs are all located within the cylindrical contour. Therefore, the number of fibers entering the barbs during needle punching is small. In other words, the needle punching efficiency and needle punching quality are difficult to meet the processing requirements. Utility Model Content
[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved pre-oxidized filament felt multi-faceted pyramidal needle.
[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0009] A multi-faceted pyramidal needle for pre-oxidized filament felt includes a needle handle and a needle-punching part. The needle handle matches a needle hole on a needle plate. The needle-punching part includes a needle shaft and a needle tip. The needle shaft forms barbs from the circumference inward. In particular, the needle shaft is prism-shaped. The barbs are recessed from the edges of the prism inward. The barbs facing the needle tip are lower barbs, and the barbs facing the needle handle are upper barbs. The lower and upper barbs are arranged in an array around the center of the prism. During needle insertion and retraction, the lower and upper barbs drive the pre-oxidized filaments to interweave up and down.
[0010] Preferably, the cross-section of the polygonal prism is a regular polygon. This ensures that the needle is subjected to uniform force and the resulting contact area is smaller, significantly reducing the needle breakage rate.
[0011] Furthermore, the needle tip is pyramidal in shape. This makes it easier to insert the needle.
[0012] In some specific implementations, the apex of the pyramid is located on the center line of the polygonal prism. This prevents material breakage caused by misalignment.
[0013] According to a specific embodiment and preferred aspect of this utility model, upper and lower barbs located on the same edge form a barb group, and multiple barb groups are distributed on the same edge. The multiple barb groups increase the interlacing rate during acupuncture, thereby improving acupuncture efficiency and quality.
[0014] Preferably, the upper and lower barbs of each barb group are symmetrically arranged. This symmetry facilitates processing and also results in uniform needle punching, improving needle punching quality.
[0015] Preferably, the barb groups are evenly spaced on the polygonal prism. This creates a relatively balanced needle position during acupuncture, reducing the needle breakage rate.
[0016] In some specific implementations, the barbs on each edge are aligned. This reduces uneven stress and lowers the needle breakage rate.
[0017] Furthermore, the needle handle includes a handle body and a needle tail shank formed on the handle body away from the needle tip, wherein the needle tail shank and the handle body are arranged perpendicularly. The vertical arrangement of the needle tail shank facilitates needle puncture and assembly with the needle plate, and also facilitates disassembly.
[0018] In some specific embodiments, the handle body comprises multiple cylindrical sections with a circular cross-section and gradually varying outer diameters. Each pair of adjacent cylindrical sections is connected by a frustum, and the center lines of the cylinders, frustums, needle shaft, and needle tip are aligned. The gradual change in diameter across the multiple cylindrical sections reduces the needle's deformation rate, thereby lowering the needle breakage rate. Furthermore, the alignment of the center lines of all sections facilitates vertical needle insertion.
[0019] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:
[0020] Existing needles have unidirectional barbs, resulting in only unidirectional needling during the needle-punching process. This leads to low needling efficiency and generally poor needle quality. Furthermore, if the hooking force is not aligned with the needling direction, the needle breakage rate increases significantly, and broken needles embed themselves within the felt, greatly complicating subsequent needle removal. Additionally, the cylindrical needle bar has a large contact area with the multi-layer mesh, pushing the fibers outwards and creating significant resistance. Moreover, the barbs are located within the cylindrical profile, resulting in a small number of fibers entering the barbs during needling. Therefore, both needling efficiency and needle quality are low. The existing technologies are insufficient to meet processing requirements, etc. However, this utility model makes an overall design of the structure of the multi-faceted pyramidal acupuncture needle, which ingeniously solves the shortcomings and defects of the prior art. After adopting this multi-faceted pyramidal acupuncture needle, the lower and upper barbs arranged on the prism drive the pre-oxidized wire to interweave up and down during the needle insertion and return. Therefore, this utility model, on the one hand, implements the interweaving of needle insertion and return based on the bidirectional movement formed by the upper and lower barbs, which greatly improves the efficiency and quality of acupuncture; on the other hand, based on the prism shape, the contact area is changed, and the array layout of the upper and lower barbs reduces the probability of deviation during the needle insertion and return, thereby reducing the needle breakage rate.

[0034] Example 1
[0035] like Figures 1 to 3 As shown, the multi-faceted acupuncture needle of the pre-oxidized filament felt in this embodiment includes a needle handle 1 and an acupuncture part 2, wherein the needle handle 1 matches the needle hole on the needle plate, and the acupuncture part 2 includes a needle shaft 20 and a needle tip 21.
[0036] Specifically, the needle handle 1 includes a handle body 10 and a needle tail handle 11 formed at the end of the handle body 10 away from the needle tip 21, wherein the needle tail handle 11 and the handle body 10 are arranged perpendicularly. The vertical arrangement of the needle tail handle facilitates needle puncture and assembly with the needle plate, and also facilitates disassembly. In some specific embodiments, the handle body 10 includes multiple cylindrical sections 100 with a circular cross-section and a gradually changing outer diameter, wherein each pair of adjacent cylindrical sections 100 is transitioned by a frustum 101, and the center lines of the cylinders 100, frustum 101, needle shank 20, and needle tip 21 are aligned. The gradual change in diameter of the multiple cylindrical sections reduces the needle deformation rate, thereby reducing the needle breakage rate, and the alignment of the center lines of the multiple sections is more conducive to vertical acupuncture.
[0037] The needle bar 20 is prismatic in shape, with barbs recessed inward from the edges of the prismatic prism. The barbs facing the needle tip are called lower barbs 200, and the barbs facing the needle shank are called upper barbs 201. Each lower barb 200 and upper barb 201 is arranged in an array around the center of the prismatic prism. During needle insertion and needle return, the lower and upper barbs drive the pre-oxidized filaments to interweave up and down.
[0038] In this example, the cross-section of the polygonal prism is an equilateral triangle. This ensures even force distribution on the needle and reduces the contact area, significantly lowering the needle breakage rate. The needle tip 21 is pyramidal. This facilitates needle insertion. The vertex of the pyramid is located on the center line of the polygonal prism, preventing misalignment and material breakage.
[0039] In some specific embodiments, upper barbs 200 and lower barbs 201 located on the same edge form a barb group G, and three barb groups G are distributed on the same edge. Multiple barb groups increase the interlacing rate during needle punching, improving needle punching efficiency and quality. The upper barbs 200 and lower barbs 201 of each barb group G are symmetrically arranged. Symmetry facilitates processing, and the resulting needle punches are uniform, improving needle punching quality. Each barb group G is evenly distributed on the polygonal prism. This results in needles with relatively balanced needle punching, reducing the needle breakage rate. The barb groups G on each edge are aligned. This reduces uneven force distribution and further reduces the needle breakage rate.
[0040] Example 2
[0041] like Figure 4 and Figure 5 As shown, the pre-oxidized filament felt of this embodiment has a multi-faceted acupuncture needle, which includes a needle handle 1 and a needle-punching part 2 with a structure similar to that of Embodiment 1. The needle-punching part 2 includes a needle shaft 20 and a needle tip 21.
[0042] In this example, the needle bar 20 and needle tip 21 are slightly different from those in Example 1, as detailed below.
[0043] The cross-section of the needle bar 20 is square, and the shape of the needle tip 21 matches the shape of the needle bar 20.
[0044] In summary, by employing this multi-faceted pyramidal acupuncture needle, the lower and upper barbs arranged on the prism drive the pre-oxidized filament to intertwine during needle insertion and return. Therefore, this invention significantly improves acupuncture efficiency and quality through the bidirectional movement formed by the upper and lower barbs during insertion and return. Furthermore, the prism shape alters the contact area, and the arrayed barbs reduce the probability of deviation during insertion, thus lowering the needle breakage rate. Thirdly, the cross-section of the multi-faceted prism is a regular polygon, ensuring uniform needle force and a smaller contact area, further reducing the breakage rate. The pyramidal tip facilitates needle insertion, and the apex of the pyramid is located on the center line of the multi-faceted prism, preventing misalignment. This leads to material breakage; fourthly, the multiple barb groups increase the interlacing rate during needle punching, improving needle punching efficiency and quality. The upper and lower barbs of each barb group are symmetrically arranged, which facilitates processing and results in uniform needle punching, improving needle punching quality. The barb groups are evenly distributed on the polygonal prism, resulting in relatively balanced needle punching and reducing needle breakage rate. In addition, the barb groups on each edge are aligned, reducing uneven force distribution and needle breakage rate. Fifthly, the vertical arrangement of the needle tail shank facilitates needle piercing and assembly with the needle plate, and also facilitates disassembly. Furthermore, the gradually changing thickness of the multi-section cylinder reduces the needle deformation rate, thereby reducing needle breakage rate, and the alignment of the center lines of multiple sections is more conducive to vertical needle punching.
[0045] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
