Abstract
Description
Technical Field
[0001] The invention relates to the field of acupuncture and moxibustion apparatus manufacturing, and more specifically to an acupuncture and moxibustion apparatus with a polygonal cross-section plastic handle and a production device and method thereof. Background Art
[0002] The acupuncture instruments in the prior art, such as plastic-handled needles and plastic-handled small needle knives, have needle handles that are mostly formed in one-shot injection molding, and have shapes such as special shapes (mainly banana fan shapes), rotating bodies (such as cylindrical shapes, etc.) or flat strips.
[0003] The production cost of the plastic handle by extrusion molding is lower than that of the injection molding process. However, when the acupuncture instruments are produced by the extrusion molding process, the needle bodies need to be inserted into the plastic handle one by one, which leads to low production efficiency. If the plastic handle with through holes is produced by injection molding, and then the needle body is assembled by post-assembly, the needle body still needs to be inserted into the plastic handle one by one, which leads to low production efficiency. Summary of the invention
[0004] 1. Technical problem to be solved by the invention
[0005] In view of the problem of low production efficiency of inserting needle bodies into plastic handles one by one during the production of traditional Chinese medicine acupuncture instruments in the prior art, the present invention provides an acupuncture instrument with a polygonal cross-section plastic handle and a production device and method thereof. Through the coordinated cooperation of a plastic handle bundling disk and a magnet, batches of needle bodies can be inserted into the plastic handle in a short period of time, thereby achieving the technical effect of improving the needle insertion efficiency.
[0006] 2. Technical solution
[0007] In order to achieve the above object, the technical solution provided by the present invention is:
[0008] A production device for acupuncture instruments with a polygonal cross-section and a plastic handle, wherein the acupuncture instruments are acupuncture needles or acupuncture needle knives, including a needle body and a plastic handle, wherein the cross-section of the plastic handle is a polygon, and a plurality of plastic handles are bundled to form a plastic handle bundling tray; the production device comprises: a needle body transfer cylinder and a magnet; the needle body transfer cylinder has a needle body stored vertically therein; the magnet is connected to the bottom of the needle body transfer cylinder; during production, the needle body transfer cylinder is turned over and inverted above the plastic handle bundling tray, and after the magnet is removed or the power is cut off, the demagnetized needle body falls freely onto the plastic handle bundling tray, and part of the needle body passes through the through hole of the plastic handle due to its own weight, thereby achieving the purpose of inserting a batch of needle bodies into a batch of plastic handles at one time and in a short time, thereby improving production efficiency.
[0009] In a further production device, the needle body is partially bent into a bent section to prevent the needle body from directly passing through the plastic handle. After the needle body is pulled in a subsequent process, the bent section is embedded in the inner wall of the plastic handle, which also serves the purpose of fixing the needle body and the plastic handle and ensuring the connection is firm.
[0010] In a further production device, the plastic handle strapping disc is round or polygonal, which is convenient for manual or automatic strapping.
[0011] In a further production device, the outer wall of the plastic handle strapping disc is disassembled and connected with a vibrator to increase the perforation rate of the needle body and further improve production efficiency.
[0012] In a further production device, the edges of the plastic handle are chamfered with smaller rounded corners to facilitate the acupuncture action during medical treatment. The through hole at the bottom of the plastic handle is a trumpet surface, which plays a certain role in guiding the needle threading and further improves the penetration rate of the needle body.
[0013] A further production device is provided, after the needle body transfer cylinder is turned over, H<L, H is the distance between the cylinder mouth and the plastic handle strapping disk, and L is the length of the needle body; the shape of the cylinder mouth of the needle body transfer cylinder is adapted to the shape of the end face of the plastic handle strapping disk, ensuring that the needle body penetrates the plastic handle due to its own weight while preventing the needle body from falling outside the plastic handle strapping disk during needle insertion.
[0014] In a further production device, the plastic handle is hexagonal, and when the plastic handles are bundled, the handles can form a honeycomb shape with a dense structure and no gaps between the plastic handles. When the needle is injected, the needle will not fall into the gaps between the plastic handles, saving the trouble of cleaning the needle later; the radius of the fillet R is ≤0.3mm, which prevents the gaps between the plastic handles caused by chamfering from being too large, ensuring that the needle will not fall into the gaps when the needle is injected.
[0015] The further production device also includes a needle wheel, a needle pressing block and a drawing clamp arranged according to the process, which draws the needle body into the plastic handle.
[0016] A production method of the above production device comprises the following steps:
[0017] The plastic-handled strapping tray is placed vertically;
[0018] When the magnet works, the needles in the needle transfer cylinder are arranged vertically to the bottom of the cylinder;
[0019] The needle transfer cylinder is turned over and placed upside down on the plastic handle bundling tray;
[0020] When the magnet is removed or the power is turned off, the demagnetized needle body falls freely onto the plastic handle bundling disc, and part of the needle body passes through the through hole of the plastic handle;
[0021] The magnet works again to attract the needle body that has not passed through the through hole of the plastic handle to the bottom of the needle body transfer cylinder again;
[0022] Remove the needle transfer cylinder, and the plastic handle bundling disc after needle insertion enters the next process.
[0023] An acupuncture and moxibustion instrument with a polygonal cross-section plastic handle is manufactured by the above production method.
[0024] 3. Beneficial effects
[0025] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:
[0026] The polygonal cross-section plastic handle acupuncture instrument and its production device and method of the present invention can be used for batch needle threading under the coordinated cooperation of the plastic handle bundling disk, the needle body transfer cylinder and the magnet, and can be produced automatically, thereby improving production efficiency and reducing production costs.

DETAILED DESCRIPTION
[0044] In order to further understand the content of the present invention, the invention is described in detail with reference to the accompanying drawings.
[0045] Example 1
[0046] The polygonal cross-section plastic handle acupuncture instrument of this embodiment is an acupuncture needle or a small acupuncture needle knife, both of which include a needle body 10 and a plastic handle 20. The color of the plastic handle 20 can be transparent or transparent or translucent, and the model or specification of the acupuncture instrument can be identified by color.
[0047] like Figure 1 As shown, the production device includes a needle transfer cylinder 2 and a magnet 3; the needle transfer cylinder 2 has multiple needles 10 stored vertically inside; the magnet 3 is connected to the bottom of the needle transfer cylinder 2, and the magnet 3 is a commonly used permanent magnet sheet or electromagnet, and its shape is adapted to the bottom of the needle transfer cylinder 2.
[0048] The method for producing acupuncture instruments with a polygonal cross-section and a plastic handle by the production device of this embodiment comprises the following steps:
[0049] 1. Extrusion molding produces a plastic handle 20, the cross section of which is polygonal, and a circular through hole is provided in the center of the prism length direction for the needle body 10 to penetrate therein later;
[0050] 2. A plurality of plastic handles 20 are bundled to form a plastic handle bundled tray 1; Figure 2 , 4 As shown in 6, the plastic handle strapping disc 1 is circular, rectangular or hexagonal, wherein the circular shape is suitable for manual strapping, and the rectangular, hexagonal or other polygonal shapes are suitable for automatic strapping by machines; when strapping with a rectangular shape, three faces are immobile, and one pressing face 8 is compressed inwardly; when strapping with a hexagonal shape, four faces are immobile, and the other two adjacent pressing faces 8 are compressed inwardly. While being compressed, an external vibrator vibrates the plastic handles 20 to rearrange them neatly and compactly;
[0051] 3. The plastic handle bundling tray 1 is placed vertically. At the same time, a batch of needle bodies 10 are placed in the needle body transfer cylinder 2. The number of needle bodies 10 is greater than the number of plastic handles 20 in the plastic handle bundling tray 1. The diameter of the needle bodies 10 is slightly smaller than the through hole diameter of the plastic handle 20, which is about 95% of the through hole diameter.
[0052] 4. The magnet 3 works, and the batch of needles 10 built into the needle transfer cylinder 2 are magnetically attracted and arranged perpendicular to the bottom of the cylinder;
[0053] 5. If Figure 1 As shown, the needle transfer cylinder 2 is turned over and placed upside down on the plastic handle bundling tray 1;
[0054] 6. Remove the magnet 3 or turn off the power. If the magnet 3 is a permanent magnet, remove it directly. If the magnet 3 is an electromagnet, turn off the power directly. Figure 3 As shown, the demagnetized needle body 10 falls freely on the plastic handle binding plate 1, and part of the needle body 10 passes through the through hole of the plastic handle 20;
[0055] 7. The magnet 3 works again to adsorb the needle body 10 that has not passed through the through hole of the plastic handle 20 to the bottom of the needle body transfer cylinder 2 again;
[0056] 8. If Figure 5 As shown, the needle transfer cylinder 2 is removed, and the plastic handle bundling disc 1 after the needle is inserted enters the next process.
[0057] The production device of this embodiment produces a method for producing acupuncture instruments with polygonal cross-section plastic handles. Part of the needle body 10 can pass through the through hole of the plastic handle 20 due to its own weight, thereby achieving the purpose of inserting a batch of needle bodies 10 into a batch of plastic handles 20 at one time and in a short time, thereby improving production efficiency.
[0058] Example 2
[0059] The production device of the polygonal cross-section plastic handle acupuncture instruments of this embodiment has the same basic structure and steps as the first embodiment, and the difference or improvement is that the needle body 10 of the acupuncture instrument is partially bent into a bending section 101, and the bending section 101 is an acute sawtooth or W-shaped wave bend, which prevents the needle body 10 from directly passing through the plastic handle 20 downward. After the needle body 10 is pulled in the later process, the bending section 101 is embedded in the inner wall of the plastic handle 20, and also serves the purpose of fixing the needle body 10 and the plastic handle 20 and the connection strength. The outer wall of the plastic handle bundling plate 1 is disassembled and connected with a vibrator to increase the perforation rate of the needle body 10 and further improve the production efficiency.
[0060] The method for producing acupuncture instruments with a polygonal cross-section and a plastic handle by the production device of this embodiment has the same basic steps as those of Embodiment 1, and the difference or improvement lies in: adding a bending step of the needle body 10: pressing a bending section 101 out of the produced needle body 10 at a specific position as required, and then inserting the needle body 10 into the plastic handle 20 in the subsequent process so that the needle body 10 can be fixed in the plastic handle 20;
[0061] In step 5, after the needle body transfer cylinder 2 is flipped over, H<L, H is the distance between the cylinder mouth and the plastic handle strapping disk, and L is the length of the needle body; the shape of the cylinder mouth of the needle body transfer cylinder 2 is adapted to the shape of the end face of the plastic handle strapping disk 1, ensuring that the needle body 10 penetrates the plastic handle 20 due to its own weight while preventing the needle body 10 from falling outside the plastic handle strapping disk 1 during needle insertion, and also preventing the needle body 10 after the hole in step 7 from being magnetically sucked into the needle body transfer cylinder 2 by the magnet 3 that is working again.
[0062] In step 6, vibration is applied to the outer wall of the plastic handle bundling disk 1 through a vibrator so that all the plastic handles 20 have the needle body 10 passing through them, and the needle tail sections 102 of the batch of needle bodies 10 that have passed through can be bundled and pulled together, and the bent sections 101 of the batch of needle bodies 10 can be pulled out and embedded in the inner wall of the corresponding plastic handle 20.
[0063] Example 3
[0064] The production device for producing acupuncture instruments with a polygonal cross-section and acupuncture handles in this embodiment has the same basic structure and steps as those in Embodiment 2, except that: Figure 7 As shown, it also includes a needle wheel 7, a needle pressing block 6 and a drawing clamp 5 arranged according to the process, and draws the needle body 10 into the plastic handle 20.
[0065] like Figure 8 As shown, the plastic handle 20 is preferably a regular hexagonal prism. When the plastic handles 20 are bundled, the handles can be honeycombed, with a dense structure. There is no gap between the plastic handles 20. When the needle body 10 is injected, the needle body 10 will not fall into the gap between the plastic handles 20, saving the trouble of cleaning the needle body 10 later. Fig.10 The edge of the plastic handle 20 shown is chamfered with a small rounded corner 201, which is convenient for the needle insertion action during medical treatment. The bottom through hole of the plastic handle 20 is a horn surface 202, which plays a certain role in guiding the needle insertion and further improves the penetration rate of the needle body 10. The radius R of the rounded corner 201 is ≤ 0.3mm, which avoids the gap between the plastic handles 20 due to the chamfer and ensures that the needle body 10 will not fall into the gap during the needle filling.
[0066] The method for producing acupuncture instruments with a polygonal cross-section and a plastic handle by the production device of this embodiment has the same basic steps as those of Embodiment 2, except that it further includes the following steps:
[0067] 9. Plastic handle 20 after threading the needle Fig. 9 As shown, by pulling the needle tail section 102, the needle body bent section 101 is pulled into the plastic handle 20: the plastic handle bundling disc 1 is unbundled, and the plastic handle 20 filled with the needle body 10 is transferred to the transverse wheel groove on the circumference of the needle wheel 7 in sequence. When the needle tail section 102 of the needle body 10 is transferred to the jaws of the drawing clamp 5, the needle pressing block 6 presses the plastic handle 20, and the jaws clamp the needle tail section 102 and pull it backwards, as shown in FIG. Fig.11 , 12As shown, the bent section 101 of the needle body 10 is pulled into a designated position in the plastic handle 20. After pulling, the excess needle body of the needle tail section 102 exposed from the plastic handle 20 is cut off. There are many ways to cut, such as laser, cutter, grinding wheel cutting, etc.
[0068] 10. Glue is injected into the through hole of the plastic handle 20 by a machine; after the glue dries, the needle body 10 and the injection molded handle 20 are firmly fixed; Fig.13 , 14 As shown, the amount of glue injected can be half the handle or the full handle, and after drying, a half-full glue dispensing section 203 or a full-full glue dispensing section 204 is formed.
[0069] The production device of this embodiment is a method for producing acupuncture instruments with a polygonal cross-section and a plastic handle. In step 6, when the needle body 10 is inserted, the needle tip can be facing upward or downward. Considering that the needle tip facing downward may cause damage to the needle tip, a visual system needs to be added in the later process to remove plastic handle needles with problematic needle tips. If the needle tip is facing downward, the wavy bend can be pushed into the plastic handle 20 instead of being pulled into the plastic handle 20, so there is no need to cut the exposed needle body part. If the needle body 20 has no needle tip when the needle is inserted, it is necessary to grind the needle tip with the handle at the end. For acupuncture small needle knife products, the navigation on the surface of the plastic handle 20 can be obtained by heating one end of the plastic handle 20 and then pressing it. Fig.15 The polygonal cross-section acupuncture needle or acupuncture needle knife including the middle navigation step 205 can also be made as shown. Fig.16 The polygonal cross-section acupuncture needle or acupuncture needle knife including the tail navigation step 206 is shown.
[0070] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure and manufacturing steps are not limited thereto. Therefore, if a person skilled in the art is inspired by it and, without departing from the purpose of the invention, designs a structure and an implementation method similar to the technical solution without creativity, they shall all fall within the protection scope of the present invention.
