DETAILED DESCRIPTION
[0044] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings.
[0045] Embodiment 1
[0046] The polygonal section plastic handle acupuncture instrument of the embodiment is a acupuncture needle or a acupuncture small needle knife, and both include a needle body 10 and a plastic handle 20. The color of the plastic handle 20 can be transparent, and can also be transparent or semi-transparent color. The color can be used to identify the model or specification of the acupuncture instrument.
[0047] As shown in Figure 1 , the production device includes a needle body transfer cylinder 2 and a magnet 3. The needle body transfer cylinder 2 internally stores a plurality of needle bodies 10 vertically. The magnet 3 is connected to the bottom of the needle body transfer cylinder 2. The magnet 3 is a commonly used permanent magnet sheet or electromagnet, and its shape is adapted to the bottom of the needle body transfer cylinder 2.
[0048] The method for producing the polygonal section plastic handle acupuncture instrument by the production device of the embodiment is as follows:
[0049] 1. The plastic handle 20 is produced by extrusion. The cross section of the plastic handle 20 is polygonal, and there is a circular through hole in the center of the length direction of the prism for the needle body 10 to pass through later.
[0050] 2. A plurality of plastic handles 20 are bundled to form a plastic handle bundling disc 1. As shown in Figure 2 , 4 , and 6, the plastic handle bundling disc 1 is circular, rectangular or hexagonal. The circular shape is suitable for manual bundling, and the rectangular and hexagonal shapes or other polygonal shapes are suitable for automatic bundling by machines. When the plastic handle bundling disc 1 is rectangular, three sides are stationary, and one pressing surface 8 is compressed inward. When the plastic handle bundling disc 1 is hexagonal, four sides are stationary, and the other two adjacent pressing surfaces 8 are compressed inward. At the same time of compression, an external vibrator vibrates the plastic handle 20 to make it rearrange neatly and densely.
[0051] 3. The plastic handle binding tray 1 is placed vertically. At the same time, a batch of needles 10 are placed in the needle transfer tube 2. The number of needles 10 is more than the number of plastic handles 20 in the plastic handle binding tray 1. The diameter is slightly smaller than the through hole diameter of the plastic handle 20, about 95% of the through hole diameter.
[0052] 4. When magnet 3 is working, the batch of needles 10 inside the needle transfer cylinder 2 are attracted by the magnet and arranged perpendicular to the bottom of the cylinder.
[0053] 5. For example Figure 1 As shown, flip the needle transfer cylinder 2 over and place it upside down above the plastic handle binding tray 1;
[0054] 6. Remove magnet 3 or disconnect the power. If magnet 3 is a commonly used permanent magnet, remove it directly. If magnet 3 is an electromagnet, disconnect the power directly. Figure 3 As shown, the demagnetized needle 10 falls freely onto the plastic handle binding tray 1, and part of the needle 10 passes through the through hole of the plastic handle 20.
[0055] 7. The magnet 3 works again, attracting the needle body 10, which 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. For example Figure 5 As shown, the needle transfer tube 2 is removed, and the plastic handle binding tray 1 after the needle is threaded enters the next process.
[0057] The method for producing polygonal cross-section plastic handle acupuncture instruments using the production apparatus of this embodiment allows some needles 10 to pass through the through holes of the plastic handle 20 due to their own weight, thereby achieving the purpose of batch needles 10 being inserted into a batch of plastic handles 20 in a short time, thus improving production efficiency.
[0058] Example 2
[0059] The production apparatus for producing polygonal cross-section plastic-handled acupuncture instruments in this embodiment has the same basic structure and steps as in Embodiment 1, with the difference or improvement being that: the needle body 10 of the acupuncture instrument is partially bent into a bent section 101, which has an acute serrated or W-shaped wavy bend. This prevents the needle body 10 from directly penetrating the plastic handle 20, and after the needle body 10 is pulled out in a subsequent process, the bent section 101 is embedded in the inner wall of the plastic handle 20, which also serves to fix the needle body 10 to the plastic handle 20 and increase the connection strength. A vibrator is detachably connected to the outer wall of the plastic handle binding tray 1 to increase the perforation rate of the needle body 10 and further improve production efficiency.
[0060] The method for producing polygonal cross-section plastic handle acupuncture instruments using the production apparatus of this embodiment is basically the same as that of Embodiment 1, except that the following difference or improvement is made: a bending step of the needle body 10 is added: the produced needle body 10 is pressed into a bent section 101 at a specific position as needed, and the needle body 10 can be fixed in the plastic handle 20 after being inserted into the plastic handle 20 in the subsequent process.
[0061] In step 5, after the needle transfer cylinder 2 is turned over, H < L, H is the distance between the cylinder opening and the plastic handle bundling disc, and L is the length of the needle body; the shape of the opening of the needle transfer cylinder 2 is matched with the end face of the plastic handle bundling disc 1, which ensures that the needle body 10 is inserted into the plastic handle 20 due to gravity while avoiding the needle body 10 from falling outside the plastic handle bundling disc 1 when the needle body 10 is inserted, and also avoids the needle body 10 from being re-magnetically attracted into the needle transfer cylinder 2 by the magnet 3 in step 7 after being perforated.
[0062] In step 6, vibration is applied to the outer wall of the plastic handle bundling disc 1 by a vibrator, so that all the plastic handles 20 have the needle body 10 inserted, and the inserted needle tail section 102 of the batch of needle bodies 10 can be bundled and pulled together. After the bent section 101 of the batch of needle bodies 10 is pulled, it is embedded into the inner wall of the corresponding plastic handle 20.
[0063] Example 3
[0064] The production device for producing the polygonal cross-section plastic handle acupuncture instrument of the present embodiment has the same basic structure and steps as those of example 2, and the difference or improvement lies in that, as shown in the figure, it further includes a needle wheel 7, a needle pressing block 6, and a pulling clamp 5 arranged according to the process, which pulls the needle body 10 into the plastic handle 20. Figure 7
[0065] As shown in the figure, the plastic handle 20 is preferably a regular hexagonal prism, and when the plastic handles 20 are bundled, the handles and the handles can form a honeycomb structure, which is compact in structure and has no gap between the plastic handles 20, so that the needle body 10 will not fall into the gap between the plastic handles 20 when it is inserted, thereby saving the trouble of cleaning the needle body 10 later; as shown in the figure, the edges of the plastic handle 20 are chamfered to a smaller radius 201, which facilitates the needle insertion action during medical treatment, and the through hole at the bottom end of the plastic handle 20 is a horn face 202, which plays a certain guiding role in needle insertion and further improves the perforation rate of the needle body 10. The radius R of the chamfer 201 is ≤0.3mm, which avoids the gap between the plastic handles 20 from being too large due to chamfering, and ensures that the needle body 10 will not fall into the gap when it is inserted. Figure 8 Figure 10
[0066] The method for producing the polygonal cross-section plastic handle acupuncture instrument by the production device of the present embodiment has the same basic steps as those of example 2, and the difference or improvement lies in that it further includes the following steps:
[0067] 9. After the plastic handle 20 is inserted with the needle, as shown in the figure, the needle tail section 102 is pulled again, and the bent section 101 of the needle body 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 horizontal wheel groove of the circumferential surface of the needle wheel 7 in sequence, the needle tail section 102 of the needle body 10 is transferred to the jaws of the pulling clamp 5, the needle pressing block 6 presses the plastic handle 20 tightly, the jaws clamp the needle tail section 102 and pull it backward, as shown in the figure. Figure 9 Figure 11 12 As shown, the bent section 101 of the needle body 10 is pulled into the specified position in the plastic handle 20, and after pulling, the excess needle body exposing the needle tail section 102 of the plastic handle 20 is cut off, and the cutting method can be various, such as laser, cutter, abrasive wheel cutting, etc.
[0068] 10, the through hole of the plastic handle 20 is injected with glue, and the through hole of the plastic handle 20 is injected with glue by machine; after the glue is dry, the needle body 10 and the plastic handle 20 are firmly fixed; such as Figure 13 、 14 As shown, the amount of injected glue can be half or full, and after drying, a half-full glue injection section 203 or a full-full glue injection section 204 is formed.
[0069] The production device of the embodiment produces a polygonal cross-section plastic handle acupuncture instrument, and in step 6, the needle body 10 can be filled with the needle tip upward or downward. Considering that the needle tip downward may cause damage to the needle tip, a visual system is needed to remove the plastic handle needle with a problem needle tip in the later process. If the needle tip is downward, the wave bend can be pushed into the plastic handle 20 instead of being pulled into the plastic handle 20 by pulling, so that the exposed needle body part does not need to be cut. If the needle body 20 has no needle tip when filling the needle, the needle tip needs to be ground at the end with the handle. For acupuncture and small needle knife products, the navigation on the surface of the plastic handle 20 can be made by heating one end of the plastic handle 20 and pressing, to make a polygonal cross-section acupuncture needle or acupuncture small needle knife including a middle navigation step 205 as shown. Figure 15 As shown, a polygonal cross-section acupuncture needle or acupuncture small needle knife including a tail navigation step 206. Figure 16 As shown, a polygonal cross-section acupuncture needle or acupuncture small needle knife including a tail navigation step 206.
[0070] The above describes the utility model and its implementation mode in a schematic manner, which is not restrictive, and the drawings shown are only one of the embodiments of the utility model, and the actual structure and manufacturing steps are not limited thereto. Therefore, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structure modes and embodiments can be designed without creativity, which should belong to the protection scope of the utility model.
