Description

Technical Field

[0001] This invention relates to the field of acupuncture needle packaging equipment technology, and in particular to a production equipment for packaging acupuncture needles and its packaging bag. Background Technology

[0002] Modern acupuncture needles mainly consist of a needle and a ratchet tube. The ratchet tube is characterized by a ratchet tooth punched into its upper part. Only the top or bottom edge of this ratchet tooth remains connected to the tube wall, while the other edges are separated from the wall and inclined inwards, locally reducing the inner diameter of the tube. This allows the needle handle to be clamped, securing the needle within the tube. Furthermore, the surface of the tube is coated with color codes, using different colors to indicate different acupuncture needle specifications. This provides physicians with clear and easily identifiable visual signals, enabling them to easily distinguish the needle from the sterile bag when it is removed, or to easily differentiate the specification of acupuncture needle when many different specifications are mixed together, thus preventing errors.

[0003] Chinese Patent Publication No. CN106809440A discloses a horizontal packaging machine for bagged acupuncture needles, including a packaging bag feeding unit, an acupuncture needle placement unit, a packaging bag degassing and heat-sealing unit, and an information printing and cutting / discharging unit. The packaging bag feeding unit conveys the strip-shaped packaging bag material to a horizontal platform. The acupuncture needle placement unit includes a needle placement wheel, vertically and tilted for rotation, with the lower needle placement port corresponding to the opening of the packaging bag; multiple needle grooves are provided on the circumference of the wheel. The packaging bag degassing and heat-sealing unit includes a pair of first pressing blocks to press the packaging bag filled with acupuncture needles, expelling air from the packaging bag. The information printing and cutting / discharging unit includes a printing mechanism and a cutting mechanism. It also includes a packaging bag driving mechanism to provide power for the movement of the packaging bag on the horizontal platform. This horizontal packaging bag design solves the problem of difficulty in stacking acupuncture needles, which limits the number of needles that can be bagged, and also solves the problem of needle tip damage during bagging.

[0004] In the existing technology, acupuncture needles are released by a needle-separating and needle-releasing wheel. However, this structure only fixes the acupuncture needles through the needle groove and the negative pressure mechanism. Since most acupuncture needles are made of metal, the negative pressure cannot provide a stable adsorption force. As a result, the acupuncture needles are easy to detach from the needle-separating and needle-releasing wheel and get stuck in the device, which can damage the device or affect product processing.

[0005] Therefore, it is necessary to provide a production equipment for acupuncture needle packaging and its packaging bag to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a production equipment for acupuncture needle packaging and its packaging bag to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a production equipment for packaging acupuncture needles, comprising a feeding mechanism for placing acupuncture needles into a packaging bag, wherein a second conveying mechanism and a first conveying mechanism are respectively provided at the top and bottom of the feeding mechanism, the second conveying mechanism feeding acupuncture needles into the feeding mechanism, the first conveying mechanism conveying a packaging base plate, and a sorting wheel for sorting acupuncture needles being driven to rotate inside the feeding mechanism by a driving mechanism, wherein needle grooves are uniformly opened on the outer surface of the sorting wheel, a negative pressure port is connected to the bottom of the needle grooves, and a limiting mechanism for limiting the acupuncture needles according to air pressure is embedded in the inner wall of the needle grooves.

The air hole is opened through the first sealing plate and the second sealing plate, and the air hole inside the first sealing plate is misaligned with the air hole inside the second sealing plate.

[0012] Furthermore, the surface of the limiting rod may be provided with a flexible layer to improve the clamping and limiting effect on the acupuncture needle, and the sealing pressure plate is made of lightweight material.

[0013] As a further embodiment of the present invention, the negative pressure port is provided with a material ejection assembly for selecting acupuncture needles in the needle groove. The material ejection assembly includes an ejection rod and a driving mechanism. The driving mechanism is embedded in the sorting wheel. The ejection rod is slidably connected to the inside of the negative pressure port. The driving mechanism drives the ejection rod to slide back and forth inside the negative pressure port. The feeding mechanism has an ejection port adapted to the material ejection assembly.

[0014] Furthermore, the acupuncture needle includes a needle body and a needle handle, the diameter of the needle body is smaller than that of the needle handle, and the needle body is fixedly embedded in the middle of the needle handle.

[0015] As a further embodiment of the present invention, the feeding mechanism is provided with two sets of oppositely arranged, the second conveying mechanism is located below the discharge port, and the acupuncture needles processed inside the two sets of feeding mechanisms face opposite directions.

[0016] As a further embodiment of the present invention, the ejector rod includes an abutting part, an ejector rod body, and a driving link. The driving link is slidably connected to the inner wall of the negative pressure port. The driving link is driven to reciprocate through a driving mechanism. The ejector rod body is fixedly connected to the middle part of the driving link. The abutting part is elastically embedded inside the ejector rod body.

[0017] Furthermore, the top of the abutting part may be provided with a flexible material such as a cotton brush, so that the abutting part can clean the surface of the needle body to a certain extent when sliding back and forth with the needle body. The main body of the ejector rod is located below the abutting point of the two sets of closed pressure plates, and the inner wall of the negative pressure port is provided with a groove that matches the drive connecting rod.

[0018] As a further embodiment of the present invention, the driving mechanism includes a sliding cavity, a driving rod, and a driving disk. The sliding cavity is opened inside the sorting wheel. The driving rod is rotatably embedded in the middle of the sliding cavity. The driving disk is rotatably sleeved on the outer end face of the driving rod. The driving disk is elastically connected to the end of the sliding cavity. The driving connecting rod is fixedly connected to the outer end face of the driving disk.

[0019] As a further embodiment of the present invention, the outer end of the drive rod is provided with a spiral groove, the drive disk is provided with a plug rod adapted to the spiral groove, the top and bottom of the plug rod are provided with inclined grooves, and the two ends of the sliding cavity are provided with inclined plug rods adapted to the inclined grooves.

[0020] Furthermore, the plug rods are symmetrically arranged in two or more sets to improve the stability of the spiral groove driving the drive disk. The top and bottom of the drive disk are provided with plug grooves that are adapted to the inclined plug rods.

[0021] As a further embodiment of the present invention, the feeding mechanism is provided with a rotating cavity adapted to the sorting wheel, the inner wall of the rotating cavity is provided with a tooth groove, and one end of the driving rod extends through the sliding cavity into the interior of the rotating cavity and meshes with the tooth groove.

[0022] Furthermore, the portion of the drive rod extending into the rotating cavity may be equipped with a gear, which meshes with the tooth groove.

[0023] As a further aspect of the present invention, an acupuncture needle packaging bag includes a packaging base plate, the packaging base plate having a placement groove, the placement groove having multiple sets of partition plates evenly arranged inside, and the partition plates having fixing grooves adapted to acupuncture needles.

[0024] When in use, the packaging base plate has mobility and a fixing groove inside to limit the acupuncture needles, which can effectively avoid the problems of acupuncture needles colliding with each other in traditional bag packaging. The packaging base plate also facilitates heat sealing, and its flat structure makes it easy to stack and transport the products.

[0025] In use, this invention incorporates a sorting wheel to improve the accuracy and efficiency of acupuncture needle feeding. The acupuncture needles are conveyed to the top of the feeding mechanism via a second conveying mechanism and fed into the feeding mechanism through a feeding port. The acupuncture needles are fixed in place by a needle groove on the surface of the sorting wheel. Simultaneously, a negative pressure port is provided at the bottom of the needle groove, and the needle groove has a trapezoidal cross-section with inclined surfaces on both sides of the inner wall. This airflow and the inclined surfaces guide the acupuncture needles, ensuring they fall to the bottom of the needle groove. Furthermore, because the acupuncture needle body is made of high-density metal, the negative pressure adsorption effect is relatively poor. To prevent the acupuncture needle from detaching from the needle groove and becoming stuck inside the feeding mechanism, further measures are taken. The device is designed to limit the acupuncture needles as they fall in, using airflow to prevent them from detaching during the rotation of the sorting wheel. When the acupuncture needle rotates to the bottom of the sorting wheel, the negative pressure in the negative pressure port closes, and the limiting mechanism engages. Simultaneously, the acupuncture needle falls vertically under gravity into the packaging base plate on the surface of the first conveying mechanism. By controlling the first conveying mechanism to transport the packaging base plate, the acupuncture needles fall into the packaging base plate one by one and are placed sequentially. Once the packaging base plate is full, it can be transported to the next packaging step to complete the packaging of the acupuncture needles. Attached Figure Description

[0040] Example 1

[0041] like Figure 1-4 As shown, a production equipment for packaging acupuncture needles includes a feeding mechanism 1 for placing acupuncture needles into a packaging bag. The top and bottom of the feeding mechanism 1 are respectively provided with a second conveying mechanism 7 and a first conveying mechanism 5. The second conveying mechanism 7 feeds acupuncture needles into the feeding mechanism 1. The first conveying mechanism 5 conveys a packaging base plate 6. Inside the feeding mechanism 1, a sorting wheel 4 for sorting acupuncture needles is driven to rotate by a driving mechanism 3. The outer surface of the sorting wheel 4 is evenly provided with needle grooves 12. The bottom of the needle grooves 12 is connected to a negative pressure port 13. The inner wall of the needle grooves 12 is embedded with a limiting mechanism 14 that limits the acupuncture needles according to air pressure.

[0042] Furthermore, the top of the feeding mechanism 1 is provided with a feeding port 2, and the bottom of the feeding mechanism 1 is provided with a discharge port that is compatible with the first conveying mechanism 5. The cross-section of the needle groove 12 is trapezoidal.

[0043] In use, a sorting wheel 4 is provided to improve the accuracy and efficiency of acupuncture needle feeding. The acupuncture needles are conveyed to the top of the feeding mechanism 1 via the second conveying mechanism 7 and then fed into the feeding mechanism 1 through the feeding port 2. The acupuncture needles are fixed by the needle grooves 12 opened on the surface of the sorting wheel 4. At the same time, a negative pressure port 13 is provided at the bottom of the needle groove 12. The cross-section of the needle groove 12 is trapezoidal, and the two sides of the inner wall of the needle groove 12 are inclined. Thus, the airflow and the inclined surfaces guide the acupuncture needles, causing them to fall to the bottom of the needle groove 12. At the same time, since the acupuncture needle body is made of metal with a high density, the negative pressure adsorption effect is poor. To prevent the acupuncture needles from detaching from the needle groove 12 and getting stuck inside the feeding mechanism 1, the negative pressure adsorption is also improved. The device is used in conjunction with a limiting mechanism 14. After the acupuncture needle falls in, the limiting mechanism 14 uses airflow to limit the acupuncture needle to prevent it from falling off during the rotation of the sorting wheel 4. When the acupuncture needle rotates with the needle groove 12 to the bottom of the sorting wheel 4, the negative pressure in the negative pressure port 13 is closed, and the limiting mechanism 14 makes contact. At the same time, the acupuncture needle falls vertically into the packaging base plate 6 on the surface of the first conveying mechanism 5 under the action of gravity. By controlling the conveying of the packaging base plate 6 by the first conveying mechanism 5, the acupuncture needles fall into the packaging base plate 6 one by one and are placed in sequence. After the packaging base plate 6 is full, it can be conveyed to the next packaging step to complete the packaging of the acupuncture needles.

[0044] Example 2

[0045] Based on Example 1, such as Figure 1 and Figure 4-8 As shown, the limiting mechanism 14 includes a limiting rod 19 and a closing pressure plate 20. The closing pressure plate 20 is rotatably connected to the bottom of the inner wall of the needle groove 12 and is horizontally arranged at the bottom of the needle groove 12. The limiting rod 19 is embedded in the inner wall of the needle groove 12 and is fixedly connected to one side of the upper end face of the closing pressure plate 20.

[0046] Furthermore, the limiting mechanism 14 is symmetrically distributed on both sides of the inner wall of the needle groove 12, and the limiting rod 19 is provided with multiple sets of evenly arranged closed pressure plates 20 on one side of the upper end face. The inner wall of the needle groove 12 is provided with a groove 22 that is adapted to the limiting rod 19, and the limiting rod 19 is flush with the surface of the needle groove 12.

[0047] like Figure 1 and Figure 4-8 As shown, the sealing plate 20 includes an air hole 26, a first sealing plate 27, and a second sealing plate 28. The first sealing plate 27 is rotatably connected to the inner wall of the needle groove 12. The first sealing plate 27 is elastically embedded in the upper end face of the second sealing plate 28. The air hole 26 is opened through the first sealing plate 27 and the second sealing plate 28, and the air hole 26 inside the first sealing plate 27 and the air hole 26 inside the second sealing plate 28 are misaligned.

[0048] Furthermore, the surface of the limiting rod 19 may be provided with a flexible layer to improve the clamping and limiting effect on the acupuncture needle, and the closed pressure plate 20 is made of lightweight material.

[0049] In use, to improve the limiting mechanism 14 by balancing airflow adsorption and limiting effects, the sealing plate 20 is divided into a first sealing plate 27 and a second sealing plate 28. In the initial state, the first sealing plate 27 and the second sealing plate 28 are separated, and the air hole 26 between the first sealing plate 27 and the second sealing plate 28 is connected through the gap between the first sealing plate 27 and the second sealing plate 28. This allows the negative pressure airflow in the negative pressure port 13 to enter the interior of the needle groove 12 through the air hole 26, and the acupuncture needle is adsorbed and fixed in the needle groove 12 by the negative pressure. At the bottom, as the acupuncture needle falls into the bottom of the needle groove 12, the acupuncture needle presses against the air hole 26, causing the first sealing plate 27 and the second sealing plate 28 to press against each other. The gap between the first sealing plate 27 and the second sealing plate 28 disappears, causing the air hole 26 to close. As a result, the negative pressure in the negative pressure port 13 will attract the sealing plate 20, causing the sealing plate 20 to rotate and push the limiting rod 19 to engage the acupuncture needle. Thus, the limiting mechanism 14 can further limit the acupuncture needle through the negative pressure of the negative pressure port 13, preventing the acupuncture needle from falling out of the needle groove 12.

[0050] like Figure 1 and Figure 2-7 As shown, the negative pressure port 13 is provided with a material ejection assembly 15 for selecting acupuncture needles in the needle groove 12. The material ejection assembly 15 includes a material ejection rod 21 and a drive mechanism 18. The drive mechanism 18 is embedded in the sorting wheel 4. The material ejection rod 21 is slidably connected to the inside of the negative pressure port 13. The drive mechanism 18 drives the material ejection rod 21 to slide back and forth inside the negative pressure port 13. The feeding mechanism 1 has a material ejection port 8 that is adapted to the material ejection assembly 15.

[0051] Furthermore, the acupuncture needle includes a needle body 16 and a needle handle 17. The diameter of the needle body 16 is smaller than that of the needle handle 17, and the needle body 16 is fixedly embedded in the middle of the needle handle 17.

[0052] In use, the acupuncture needles are selected by the ejector assembly 15. Because the needle body 16 faces differently when the acupuncture needles are fed, the needle tips face differently after packaging, which is inconvenient to use and poses certain safety risks. Therefore, the ejector assembly 15 is provided. The ejector assembly 15 has an ejector rod 21 that slides back and forth inside the negative pressure port 13. When the acupuncture needle is fixed at the bottom of the needle groove 12, part of the needle handle 17 will enter the inside of the negative pressure port 13. The ejector rod 21 slides partially inside the negative pressure port 13. As the ejector rod 21 slides, it will come into contact with the end face of the needle handle 17 or the bottom of the needle body 16. As the ejector rod 21 slides, the needle handle 17 is pushed out of the needle groove 12 and the acupuncture needle is discharged from the feeding mechanism 1 through the ejector port 8. This completes the unidirectional selection of the ejector assembly 15, so that the needle tips of the acupuncture needles inside the needle groove 12 face the same direction.

[0053] like Figure 1 and Figure 2-6 As shown, the feeding mechanism 1 has two sets arranged opposite to each other, and the second conveying mechanism 7 is located below the discharge port 8. The acupuncture needles processed inside the two sets of feeding mechanisms 1 face opposite directions.

[0054] In use, two sets of feeding mechanisms 1 are provided to select acupuncture needles with different orientations. When the acupuncture needles are conveyed by the second conveying mechanism 7, the acupuncture needles with different orientations will be discharged through the discharge port 8 under the action of the unloading component 15 and fall into the second conveying mechanism 7 of the other feeding mechanism 1. Thus, the acupuncture needles with different orientations are sorted by the unloading component 15 and fall back into the second conveying mechanism 7 through the discharge port 8. This allows the sorted materials to be directly used for subsequent processing, greatly improving the processing efficiency of the device.

[0055] like Figure 1 and Figure 3-7 As shown, the ejector rod 21 includes an abutment part 23, an ejector rod body 24, and a drive link 25. The drive link 25 is slidably connected to the inner wall of the negative pressure port 13. The drive link 25 is driven to reciprocate through the drive mechanism 18. The ejector rod body 24 is fixedly connected to the middle of the drive link 25. The abutment part 23 is elastically embedded inside the ejector rod body 24.

[0056] Furthermore, the top of the abutting part 23 may be provided with a flexible material such as a cotton brush, so that the abutting part 23 can clean the surface of the needle body 16 to a certain extent when it slides back and forth against the needle body 16. The ejector rod body 24 is located below the joint of the two sets of closed pressure plates 20, and the inner wall of the negative pressure port 13 is provided with a groove that matches the drive connecting rod 25.

[0057] In use, the drive mechanism 18 drives the drive linkage 25 to move the ejector rod body 24 inside the negative pressure port 13. At this time, the abutment part 23 is in contact with the needle body 16 or the needle handle 17 under the action of weak elasticity. If the abutment part 23 is in contact with the needle body 16, the direction of the acupuncture needle is correct. If the abutment part 23 is in contact with the needle handle 17, the direction of the acupuncture needle is reversed and ejection is required. As the abutment part 23 moves, the abutment part 23 is in contact with the needle handle 17 and then disengages. After disengagement, the abutment part 23 moves upward and is in contact with the needle body 16. When the abutment part 23 returns, it will be in contact with the end of the needle handle 17 and push the needle handle 17 out of the needle outlet groove 12. After disengagement, the acupuncture needle is discharged through the ejector port 8 and the discharge mechanism 1 is discharged, thus completing the ejection of the acupuncture needle with the wrong orientation. If the direction of the acupuncture needle is correct, the abutment part 23 provides a certain support for the needle body 16, and its reciprocating sliding can also clean the surface of the needle body 16 to avoid the adhesion of impurities or dust.

[0058] like Figure 1 and Figure 4-9 As shown, the drive mechanism 18 includes a sliding cavity 29, a drive rod 30, and a drive disk 31. The sliding cavity 29 is opened inside the sorting wheel 4. The drive rod 30 is rotatably embedded in the middle of the sliding cavity 29. The drive disk 31 is rotatably sleeved on the outer end face of the drive rod 30. The drive disk 31 is elastically connected to the end of the sliding cavity 29. The drive connecting rod 25 is fixedly connected to the outer end face of the drive disk 31.

[0059] like Figure 1 and Figure 4-11 As shown, the outer end of the drive rod 30 is provided with a spiral groove 32, and the drive disk 31 is provided with a plug rod 35 that is adapted to the spiral groove 32. The top and bottom of the plug rod 35 are provided with inclined grooves 34, and the two ends of the sliding cavity 29 are provided with inclined plug rods 36 that are adapted to the inclined grooves 34.

[0060] Furthermore, the plug rods 35 are symmetrically provided in two or more sets to improve the stability of the spiral grooves 32 driving the drive disk 31. The top and bottom of the drive disk 31 are provided with plug grooves 33 that are adapted to the inclined plug rods 36.

[0061] In use, the rotation of the drive rod 30 drives the drive disc 31 to reciprocate within the sliding cavity 29, thereby driving the drive linkage 25 to move. The intermittent adaptation between the drive disc 31 and the drive rod 30, along with the elasticity between the drive disc 31 and the sliding cavity 29, completes the autonomous reciprocating motion of the drive disc 31. Inside the drive disc 31, the insertion rod 35 engages with the spiral groove 32. At this time, the rotation of the drive rod 30 moves the drive disc 31, compressing the spring at the end of the sliding cavity 29. When the drive disc 31 moves to contact the inclined insertion rod 36 at the end of the sliding cavity 29, the inclined insertion rod 36 inserts into the insertion groove 33 and engages with the inclined surface of the insertion rod 35. The groove 34 fits, thus pushing the insertion rod 35 to move inside the drive disk 31 under the action of the inclined groove 34, causing the insertion rod 35 to disengage from the spiral groove 32. The drive disk 31 quickly resets under the action of the elastic force. When the drive disk 31 moves to the other end of the sliding cavity 29, the inclined insertion rod 36 is inserted into the other side of the drive disk 31, and pushes the insertion rod 35 to reset under the action of the inclined groove 34. The insertion rod 35 refits with the spiral groove 32. At this time, the drive rotating rod 30 will continue to drive the drive disk 31 to move. This process is repeated, thereby realizing the reciprocating movement of the ejector rod 21 driven by the drive mechanism 18 to complete the ejection operation.

[0062] Example 3

[0063] Based on Example 1 or 2, such as Figure 1 and Figure 4-11 As shown, the feeding mechanism 1 has a rotating cavity 37 that is adapted to the sorting wheel 4. The inner wall of the rotating cavity 37 is provided with a toothed groove 38. One end of the driving rod 30 extends through the sliding cavity 29 into the interior of the rotating cavity 37 and meshes with the toothed groove 38.

[0064] Furthermore, the portion of the drive rod 30 extending into the rotating cavity 37 may be equipped with a gear, which meshes with the tooth groove 38.

[0065] In use, as the sorting wheel 4 rotates and the feeding mechanism 1 remains stationary, the drive rod 30 rotates under the action of the tooth groove 38 as the sorting wheel 4 rotates, so that the drive rod 30 does not require additional power to drive, and the device structure is more streamlined.

[0066] like Figure 1-2 As shown, an acupuncture needle packaging bag includes a packaging base plate 6, the packaging base plate 6 has a placement groove 11, a plurality of partition plates 9 are evenly arranged inside the placement groove 11, and a fixing groove 10 adapted to the acupuncture needle is provided between the partition plates 9.

[0067] In use, the packaging base plate 6 has mobility and the fixing groove 10 inside the packaging base plate 6 limits the acupuncture needles to a certain extent, thereby effectively avoiding the problems of mutual collision of acupuncture needles in traditional bag packaging. The packaging base plate 6 is also easy to heat-press seal, and the flat structure of the packaging base plate 6 also facilitates the stacking and transportation of products.

[0068] Working Principle: To improve the accuracy and efficiency of acupuncture needle feeding, a sorting wheel 4 is provided. The acupuncture needles are conveyed to the top of the feeding mechanism 1 via the second conveying mechanism 7 and then fed into the feeding mechanism 1 through the feeding port 2. The acupuncture needles are fixed by the needle grooves 12 on the surface of the sorting wheel 4. At the same time, a negative pressure port 13 is provided at the bottom of the needle groove 12. The cross-section of the needle groove 12 is trapezoidal, and the two sides of the inner wall of the needle groove 12 are inclined. Thus, the airflow and the inclined surfaces guide the acupuncture needles, causing them to fall to the bottom of the needle groove 12. Since the acupuncture needle body is made of metal with a high density, the negative pressure adsorption effect is poor. To prevent the acupuncture needles from detaching from the needle groove 12 and getting stuck inside the feeding mechanism 1, affecting the use of the device, a limiting mechanism 14 is also provided. The limiting mechanism 14 is used for acupuncture needle feeding. After the needle falls in, airflow is used to limit the acupuncture needle to prevent it from detaching during the rotation of the sorting wheel 4. When the acupuncture needle rotates with the needle groove 12 to the bottom of the sorting wheel 4, the negative pressure in the negative pressure port 13 closes, and the limiting mechanism 14 engages. At the same time, the acupuncture needle falls vertically under gravity into the packaging base plate 6 on the surface of the first conveying mechanism 5. By controlling the conveying of the packaging base plate 6 by the first conveying mechanism 5, the acupuncture needles fall into the packaging base plate 6 one by one and are placed sequentially. After the packaging base plate 6 is full, it can be conveyed to the next packaging step to complete the packaging of the acupuncture needles. To improve the limiting mechanism 14 by taking into account both airflow adsorption and limiting effects, the sealing plate 20 is divided into a first sealing plate 27 and a second sealing plate 28. In the initial state, the first... The sealing plate 27 and the second sealing plate 28 separate. The air hole 26 between the first sealing plate 27 and the second sealing plate 28 is connected through the gap between the first sealing plate 27 and the second sealing plate 28, so that the negative pressure airflow in the negative pressure port 13 can enter the interior of the needle groove 12 through the air hole 26. The negative pressure attracts the acupuncture needle and fixes the acupuncture needle to the bottom of the needle groove 12. As the acupuncture needle falls to the bottom of the needle groove 12, the acupuncture needle presses against the air hole 26, so that the first sealing plate 27 and the second sealing plate 28 are pressed together, the gap between the first sealing plate 27 and the second sealing plate 28 disappears, and the air hole 26 closes. Thus, the negative pressure in the negative pressure port 13 will attract the sealing plate 20, causing the sealing plate 20 to rotate and push the limiting rod 19 to lock the acupuncture needle, thereby... The limiting mechanism 14 further limits the acupuncture needles by applying negative pressure through the negative pressure port 13, preventing the acupuncture needles from detaching from the needle groove 12. A material ejection assembly 15 selects the acupuncture needles. Because the needle bodies 16 face differently during feeding, the needle tips may have different orientations after packaging, which is inconvenient and poses a safety risk. Therefore, the material ejection assembly 15 is provided. The material ejection assembly 15 uses an ejection rod 21 that slides back and forth inside the negative pressure port 13. When the acupuncture needle is fixed at the bottom of the needle groove 12, part of the needle handle 17 enters the inside of the negative pressure port 13. The ejection rod 21 partially slides inside the negative pressure port 13, thus contacting the end face of the needle handle 17 or the bottom of the needle body 16.As the ejector rod 21 slides, the needle handle 17 is pushed out of the needle groove 12, and the acupuncture needle exits the feeding mechanism 1 through the ejector port 8, thus completing the unidirectional selection of the ejector assembly 15. This ensures that the needle tips of the acupuncture needles inside the needle groove 12 are aligned. Two feeding mechanisms 1 are provided to select acupuncture needles with different orientations. When the acupuncture needles are conveyed by the second conveying mechanism 7, acupuncture needles with orientations different from the preset orientation will be discharged through the ejector port 8 under the action of the ejector assembly 15 and fall into the second conveying mechanism 7 of the other feeding mechanism 1. This allows acupuncture needles with different orientations to fall back into the second conveying mechanism 7 through the ejector port 8 after being sorted by the ejector assembly 15. This allows the sorted material to be directly used for subsequent processing, greatly improving the processing efficiency of the device. This is achieved through the drive mechanism. The drive linkage 25 of mechanism 18 drives the ejector rod body 24 to move inside the negative pressure port 13. At this time, the abutment part 23 is in contact with the needle body 16 or the needle handle 17 under the action of weak elasticity. If the abutment part 23 is in contact with the needle body 16, the direction of the acupuncture needle is correct. If the abutment part 23 is in contact with the needle handle 17, the direction of the acupuncture needle is reversed and ejection is required. As the abutment part 23 moves, it disengages from the needle handle 17. After disengagement, the abutment part 23 moves upward and is in contact with the needle body 16. When the abutment part 23 returns, it will be in contact with the end of the needle handle 17 and push the needle handle 17 out of the needle outlet groove 12. After disengagement, the acupuncture needle is discharged through the ejector port 8 and the discharge mechanism 1 is discharged, thus completing the ejection of the acupuncture needle with the wrong orientation. If the direction of the acupuncture needle is correct, the abutment part 23 provides a certain support for the needle body 16. Simultaneously, its reciprocating sliding can also clean the surface of the needle body 16 to prevent impurities or dust from adhering. The rotation of the drive rod 30 drives the drive disc 31 to reciprocate inside the sliding cavity 29, thereby driving the drive connecting rod 25 to move. Through the intermittent adaptation between the drive disc 31 and the drive rod 30, and the elasticity between the drive disc 31 and the sliding cavity 29, the drive disc 31 completes its autonomous reciprocating motion. The insertion rod 35 inside the drive disc 31 engages with the spiral groove 32. At this time, the rotation of the drive rod 30 drives the drive disc 31 to move and compress the spring at the end of the sliding cavity 29. When the drive disc 31 moves to fit with the inclined insertion rod 36 at the end of the sliding cavity 29, the inclined insertion rod 36 inserts into the insertion groove 33 and fits with the inclined groove 34 of the insertion rod 35, thereby pushing the insertion rod under the action of the inclined groove 34. The rod 35 moves inside the drive disk 31, causing the insertion rod 35 to disengage from the spiral groove 32. The drive disk 31 quickly resets under the action of the elastic force. When the drive disk 31 moves to the other end of the sliding cavity 29, the inclined insertion rod 36 inserts into the other side of the drive disk 31 and pushes the insertion rod 35 to reset under the action of the inclined groove 34. The insertion rod 35 re-adapts to the spiral groove 32. At this time, the drive rotating rod 30 will continue to drive the drive disk 31 to move. This process repeats, thereby realizing the reciprocating movement of the unloading rod 21 driven by the drive mechanism 18 to complete the unloading operation. As the sorting wheel 4 rotates and the feeding mechanism 1 remains stationary, the drive rotating rod 30 rotates under the action of the toothed groove 38, so that the drive rotating rod 30 does not require additional power to drive.The device structure is more streamlined.
