Description

Technical Field

[0001] The utility model relates to the field of acupuncture needle manufacturing, and more specifically to a plastic handle acupuncture needle and a bending and dispensing fixing device thereof. Background Art

[0002] The existing plastic handle acupuncture needle includes a needle body and a plastic handle. The needle body needs to be inserted into the cylindrical plastic handle and fixed. Generally, it is fixed by dispensing glue and then irradiating with an ultraviolet lamp. The current dispensing method is generally to insert the needle body into the plastic handle and penetrate the plastic handle. As Figure 11 shown, at the vertical glue inlet point 200 where the upper part of the plastic handle contacts the needle body, glue is leaked in a vertical downward manner (the needle body is not bent), and the glue flows into the plastic handle by its own weight. After dispensing, it is fixed by irradiating with an ultraviolet lamp; this glue inlet method requires manually holding the bottom 300 of the plastic handle through a thimble plate 400 as Figure 12 shown, resulting in the needle body not being flush with the bottom end of the plastic handle. Due to the certain viscosity of the UV glue, when dispensing glue for the plastic handle needle, there will be some uneven distribution of the glue amount due to the leakage curved surface, making the connection strength of the dispensing uneven, and the consistency of the produced plastic handle acupuncture needle products is poor.

[0003] The applicant of this application applied for a patent application with the application number 201910592510.5 on July 1, 2019, and disclosed a batch production process for plastic handle acupuncture needles. In the production process of this invention, a batch of plastic handles are fixed in a plastic handle fixture, and a batch of needle bodies are fixed in a needle body fixture; the batch of plastic handle fixtures are pushed towards the needle body bearing groove, so that the batch of needle bodies are inserted from one end of the batch of plastic handles, and then a vertical frame is inserted into the top of the batch of plastic handles; the batch of needle body fixtures and the batch of plastic handle fixtures are opened, and the vertical frame carrying the batch of needle bodies and the batch of plastic handles is taken out; batch dispensing is carried out at the contact positions between the needle handles of each plastic handle needle and the corresponding needle bodies; finally, the vertical frame is placed on a conveyor belt for ultraviolet light irradiation and curing. After the plastic handle acupuncture needles are separated from the vertical frame, the finished products are obtained. The entire operation process can achieve rapid batch production. This invention is operated through fixtures, and it is difficult to achieve automated production. Moreover, there will be some uneven glue amounts during dispensing, making the connection strength of the dispensing uneven. Content of the Utility Model

[0004] 1. Technical Problems to be Solved by the Utility Model

[0005] In view of the problem that in the prior art, when the needle body and the plastic handle of acupuncture needle for traditional Chinese medicine are fixedly connected by glue dispensing, the connection strength is uneven and the product consistency is poor, the utility model provides a plastic-handled acupuncture needle and a bending glue dispensing fixing device thereof, which is achieved by bending a batch of needle bodies and pushing them into a batch of plastic handles and then precisely dispensing glue in batches, and then curing the glue by ultraviolet light. The colloid formed after solidification produces a synergistic effect with the bending of the batch of needle bodies. The structure of the needle body inside the plastic handle and the glue dispensing method are improved, thereby achieving the purpose of improving the uniformity of the connection strength and the consistency of batch products.

[0006] 2. Technical solution

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is:

[0008] A bending and gluing fixing device for acupuncture needles with plastic handles is provided. The bending sections are bent in parallel in batches, and the bending sections are pushed back into the corresponding batches of plastic handles. Then, the bending sections and the contact sections in the plastic handles are fixed by gluing in batches. The needle bodies are bent in batches and then fixed by gluing in batches. After the colloid solidifies, it cooperates with the bending in the small perforated space of the plastic handle. The improvement of the structure of the needle body inside the plastic handle and the gluing method effectively improves the firmness of the glue connection between the needle body and the plastic handle. Moreover, the bending and gluing are performed in the process of circulating transmission on the conveyor belt along the circulating conveying route by the feeding plate. As long as the conveying speed of the conveyor belt is controlled well, the purpose of batch bending and gluing can be achieved, thereby achieving the effect of stable product quality consistency.

[0009] A further bending and dispensing fixing device comprises the steps of:

[0010] S1, the feeding plate is circulated on the conveyor belt along the circulatory conveying route, and the conveying speed is controlled and adjusted according to the product requirements;

[0011] S2, the feeding plate circulates to the bottom of the silo, a blanking slot is opened at the bottom of the silo, and the needle bodies and plastic handles in the silo are dropped in batches and parallel onto the feeding plate;

[0012] S3, the feeding plate circulates to the bottom of the needle threading mechanism, and the needle threading mechanism threads the batch of needle bodies into the batch of plastic handles, and the tail section of the needle body passes out of the plastic handle;

[0013] S4, the feeding plate circulates to the bending mechanism, and the bending mechanism bends the tail section of the batch of needle bodies into a bent section; the tail section can also be roughened and flattened;

[0014] S5, the feeding plate circulates to the push pin plate, and the push pin plate pushes the bending section back into the plastic handle;

[0015] S6. The feeding flat plate circulates to the dispensing mechanism, and the dispensing mechanism laterally injects glue through the end hole of the plastic handle to the bent section; after the glue is laterally injected into the end hole of the plastic handle, the glue wraps the bent section. Since the push pin plate pushes the bent section back into the plastic handle, there is no needle body blocking at the end hole of the plastic handle at this time, making the dispensing more convenient and smooth.

[0016] S7. The feeding flat plate circulates to the ultraviolet fixing lamp, and the ultraviolet fixing lamp solidifies the glue. The solidified glue coats the bent section, and the bent section forms a glue-fixed section inside the plastic handle, obtaining a plastic handle acupuncture needle.

[0017] S8. The feeding flat plate circulates to the manipulator, and the manipulator batch-transfers the plastic handle acupuncture needles to the finished product tray.

[0018] For the further bending, dispensing and fixing device, the material bin has a downward-receiving structure with a slit at the bottom, and a baffle is slidably connected at the slit. When feeding materials, the baffle is opened, and the material bin is separated by a partition into a plastic handle hopper and a needle body hopper on both sides of the partition; the material-taking end of the manipulator is a flexible suction cup.

[0019] For the further bending, dispensing and fixing device, the surface of the feeding flat plate is horizontally provided with a connected needle body groove and a plastic handle groove, and the needle body and the plastic handle are respectively fed into the needle body groove and the plastic handle groove.

[0020] For the further bending, dispensing and fixing device, the diameters of the needle body groove and the plastic handle groove respectively match the needle body and the plastic handle, so as to facilitate the free-fall placement of the needle body and the plastic handle.

[0021] For the further bending, dispensing and fixing device, a needle sweeping limit plate is also arranged outside the needle-piercing mechanism to level the batch of needle bodies after needle piercing, facilitating the subsequent bending operation.

[0022] For the further bending, dispensing and fixing device, the bending mechanism is a pair of pressing wheels symmetrically arranged up and down, and the circumferential surfaces of the two pressing wheels are provided with annular grooves that are vertically offset from each other, and the number of annular grooves is set as required.

[0023] For the further bending, dispensing and fixing device, the material bin, the needle-piercing mechanism, the bending mechanism, the push pin plate, the dispensing mechanism, the ultraviolet fixing lamp and the manipulator arranged in sequence according to the process form a bending, dispensing and fixing device for plastic handle acupuncture needles.

[0024] A plastic handle acupuncture needle includes a needle body and a plastic handle. The bent section of the needle body forms a glue-fixed section after the glue is dispensed and solidified inside the plastic handle, and the glue-fixed section fixedly connects the needle body and the plastic handle.

[0025] 3. Beneficial effects

[0026] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0027] (1) The plastic handle acupuncture needle and its bending and dispensing fixing device of the present utility model are improvements in the structure and dispensing method of the needle body inside the plastic handle. Compared with the vertical leakage type glue injection with uneven distribution of glue volume, the tail section of the needle body is bent into a W shape or a single bend, and after horizontal high-pressure glue injection, the glue wraps the W bend or single bend. The two cooperate with each other, and the injected glue volume is evenly distributed, increasing the bonding strength and uniformity of the glue; of course, the tail section of the needle body is not limited to a W bend or a single bend, and can also be a roughened surface and a flattened surface, both of which can improve the bonding strength;

[0028] (2) The plastic handle acupuncture needle and its bending and dispensing fixing device of the present utility model dispense glue through a precision glue dispensing head, strictly controlling the glue volume, glue dispensing speed and frequency to ensure uniform glue flow and uniform glue volume;

[0029] (3) The plastic handle acupuncture needle and its bending and dispensing fixing device of the present utility model move the glue dispensing point from the position where the needle body penetrates into the plastic handle to the tail end of the plastic handle. Since there is no needle body blocking, the glue dispensing is more convenient; of course, it can also not be moved to the tail end, and the glue is still dispensed at the position where the needle body penetrates, and the corresponding bending section is also arranged inside the front port of the plastic handle, that is, the penetration end of the needle body;

[0030] (4) The plastic handle acupuncture needle and its bending and dispensing fixing device of the present utility model can adopt automated production, reducing and avoiding the instability of manual operation, improving the stability of glue dispensing; it can also improve production efficiency and reduce production costs.

[0051] Embodiment

[0052] The plastic handle acupuncture needles of this embodiment are of three types as shown in Figure 2 , 3 , 4 respectively, and all include a needle body 21 and a plastic handle 22. After the bending section 23 of the needle body 21 is solidified by dispensing glue inside the plastic handle 22, a glue fixing section 25 is formed; after the glue is solidified by dispensing, the dispensing glue forms a glue fixing section 25 that is fixedly connected in a covering manner in the through hole of the plastic handle 22 for the bending section 23 of the needle body 21. Processing is carried out through a bending and dispensing fixing device, as shown in Figure 1 . The bending and dispensing fixing device includes a material bin 1, a needle threading mechanism 4, a bending mechanism 5, a needle pushing plate 6, a dispensing mechanism 7, an ultraviolet fixing lamp 8, and a manipulator 9 arranged in sequence according to the process to form a bending and dispensing fixing device for plastic handle acupuncture needles. As shown in Figure 1As shown, the silo 1 is a downward-closing structure with a slit at the bottom, and a baffle plate 15 is slidably connected to the slit. When the material is dropped, the baffle plate 15 is opened, and the silo 1 is divided into a plastic handle hopper 12 and a needle body hopper 13 on both sides of the partition 11 by the partition 11; Figure 7 As shown, the surface of the feeding plate 3 is horizontally arranged in parallel, and the needle body groove 31 and the plastic handle groove 32 are corresponding to each other and connected. The needle body 21 and the plastic handle 22 are dropped into the needle body groove 31 and the plastic handle groove 32 respectively; the outer edge of the plastic handle groove 32 can be in a vertical semi-closed state to prevent the plastic handle 22 from moving with the needle body 21 when threading the needle. Usually, since the needle body 21 is thin and light, the plastic handle 22 has a certain friction force in the plastic handle groove 32. When threading the needle, the needle body 21 cannot move the plastic handle 22, and the outer edge of the plastic handle groove 32 does not need to be semi-closed. The needle body groove 31 and the plastic handle groove 32 are arc-shaped or semicircular, and their diameters are respectively adapted to the diameters of the needle body 21 and the plastic handle 22, and can be slightly larger by 1 to 2%, so as to facilitate the drop-in placement of the needle body 21 and the plastic handle 22. As shown Figure 8 As shown, the needle threading mechanism 4 uses a needle sweeping machine, including a needle sweeping motor 41 and a needle sweeping wheel 42 connected to the output shaft of the needle sweeping motor 41. When the feeding plate 3 circulates to the bottom of the needle sweeping machine, the longitudinal needle sweeping wheel 42 rotates and sweeps the batch of needle bodies 21 in a horizontal row into the corresponding batch of plastic handles 22, and the tail section of the needle body 21 passes through the plastic handle 22. A vertical needle sweeping limit plate 43 is also provided on the outside of the needle threading mechanism 4 to align the batch of needle bodies 21 after threading, which is convenient for the subsequent bending action. Figure 10 As shown, the bending mechanism 5 is a pair of pressing wheels 50 symmetrically arranged in the upper and lower parts. The circumferential surfaces of the two pressing wheels 50 are provided with annular grooves 51 staggered in the upper and lower parts. The number of annular grooves 51 is set according to the needs. For single folding, a single groove is sufficient; for W-shaped wave bending, the number of corresponding upper and lower staggered annular grooves 51 is designed according to the number of wave bending; when the tail section of the needle body 21 needs to be roughened, the circumferential surfaces of the two pressing wheels 50 are provided with frosted surfaces; when the tail section of the needle body 21 needs to be flattened, the circumferential surfaces of the two pressing wheels 50 are provided with extrusion surfaces. Figure 9 As shown, the dispensing mechanism 7 is an existing precision dispensing head, and the front part thereof is a dispensing needle 71; Figure 1 As shown, the material taking end of the manipulator 9 is a flexible suction cup 91, which magnetically transfers the plastic-handled acupuncture needles 2 in batches to the finished product tray.

[0053] The method for batch manufacturing plastic handle acupuncture needles of this embodiment is as follows: Figure 1 As shown, the steps include:

[0054] S1, the feeding plate 3 is circulated on the conveyor belt along the circulatory conveying route 100, and the conveying speed is controlled and adjusted according to the product requirements;

[0055] S2. The feeding flat plate 3 cycles to the bottom of the storage bin 1. A blanking slit is opened at the bottom of the storage bin 1. The baffle plate 15 is opened. The needles 21 in the needle body hopper 13 and the plastic handles 22 in the plastic handle hopper 12 are respectively batch-fed and arranged side by side into the needle body groove 31 and the plastic handle groove 32 on the feeding flat plate 3.

[0056] S3. The feeding flat plate 3 cycles to the bottom of the needle sweeping machine. The vertically arranged needle sweeping wheel 42 rotates and sweeps the batch of horizontally arranged needles 21 into the corresponding batch of plastic handles 22 one by one. The tail section of the needle 21 passes through the outside of the plastic handle 22. The needle sweeping limit plate 43 levels the tail sections of the batch of needles 21 after needle insertion and controls the length of the protruding tail section of the needle 21.

[0057] S4. The feeding flat plate 3 cycles to the bending mechanism 5. The bending mechanism 5 bends the tail sections of the batch of needles 21 into a bent section 23, bending it into a W-shaped bend as shown in Figure 1 、 6 or a single bend as shown in Figure 5 . The bending amplitude is less than or equal to the vertical through-hole diameter of the plastic handle 22; alternatively, the tail section can be treated with a rough surface or a flattened surface.

[0058] S5. The feeding flat plate 3 cycles to the needle pushing plate 6. The needle pushing plate 6 pushes the bent section 23 back into the plastic handle 22.

[0059] S6. The feeding flat plate 3 cycles to the dispensing mechanism 7. The glue outlet needle 71 injects glue horizontally from the end hole of the plastic handle 22 to the bent section 23. The glue used is UV glue, which has strong ultraviolet photosensitivity. During dispensing, the glue volume, dispensing speed, and frequency are strictly controlled to ensure uniform glue flow and uniform glue volume. After the glue is horizontally injected into the end hole of the plastic handle 22, the glue wraps the bent section 23. Since the needle pushing plate 6 pushes the bent section 23 back into the plastic handle 22, there is no needle 21 blocking at the end hole of the plastic handle 22 at this time, which will not interfere with the glue injection, making the dispensing more convenient and smooth. The glue outlet needle 71 dispenses glue at the position where the needle 21 penetrates into the front end of the plastic handle 22. The corresponding bent section 23, as shown in Figure 4 , also needs to be set inside the front end port of the plastic handle 22.

[0060] S7. The feeding flat plate 3 cycles to be irradiated by the ultraviolet fixing lamp 8. After irradiation by the ultraviolet fixing lamp 8, the glue dries and solidifies. The solidified glue coats the bent section 23, and the bent section 23 forms a glue-fixed section 25 inside the plastic handle 22, obtaining the plastic handle acupuncture needle 2.

[0061] S8. The feeding flat plate 3 cycles to the manipulator 9. By pushing the flexible suction cup 91 at the end of the manipulator 9 through the air cylinder, the batch of plastic handle acupuncture needles 2 are magnetically adsorbed, transferred, demagnetized, and dropped from the feeding flat plate 3 into the finished product tray.

[0062] As shown in Figure 7The cyclic moving and needle feeding method of the feeding flat plate 3 shown can achieve automated operations at each station, improving the automation level of the batch production of plastic handle acupuncture needles. The feeding flat plate 3 can also implement cyclic operations at each station on any other planar or non-planar feeding device, which essentially belongs to the protection scope of the present utility model.

[0063] As Figure 2 、 3 、5, 6 are compared with the existing Figure 11 shown. The plastic handle acupuncture needle and its batch manufacturing method in this embodiment are an improvement on the structure and dispensing method of the needle body inside the plastic handle 22. Compared with the existing vertical leakage type glue injection, when the glue freely leaks downward due to its own viscosity, it will form a curved surface infiltration, resulting in uneven distribution of the glue amount. For the plastic handle acupuncture needle with the improved internal structure and dispensing method in this embodiment, the tail section of the needle body 21 is pressed into a W bend or a single-channel bend. After the glue outlet needle 71 of the precision dispensing head performs transverse high-pressure glue injection, the glue wraps the W bend or the single-channel bend, and the two cooperate with each other, without generating a leakage curved surface, and the injected glue amount is evenly distributed, increasing the bonding strength and uniformity of the glue; of course, the tail section of the needle body is not limited to the W bend or the single-channel bend, and can also be a roughened surface and a flattened surface, both of which can improve the bonding strength and the uniformity and consistency of the product, with strong processing flexibility, and can be designed accordingly according to the product needs; it can be circulated and driven on the conveyor belt along the cyclic conveying route 100 by the feeding flat plate 3, adopting automated production, reducing and avoiding the instability of manual operation, and improving the stability of the glue injection and fixed connection; it can also improve production efficiency and reduce production costs.

[0064] The above-mentioned batch precision glue injection method can also be implemented by using any other suitable glue injection method, not limited to the above method. Glue is batch-fed to the bent section 23 of the needle body that has been bent and has entered the plastic handle 22, so as to form the glued section 25 of each finished product, further improving the production efficiency of the batch finished products to ensure the stability of the quality of the plastic handle acupuncture needle batch products.

[0065] The above has schematically described the present utility model and its implementation manners. This description is not restrictive, and what is shown in the drawings is only one of the implementation manners of the present utility model. The actual structure and manufacturing steps are not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the spirit of the present invention, they shall all belong to the protection scope of the present utility model.
