Description

Technical Field

[0001] The present invention belongs to the technical field of packaging equipment, and particularly relates to an automatic syringe packaging machine. Background Art

[0002] In the field of medical supplies production, syringes, as commonly used medical devices, their production and packaging processes are crucial. Traditional syringe packaging methods mostly rely on manual operations or simple semi-automatic equipment, with many drawbacks.

[0003] In the syringe feeding process, continuous feeding was often used in the past, making it difficult to accurately control the feeding quantity, resulting in material waste or inaccurate packaging quantity. Moreover, manual feeding is slow and labor-intensive, seriously affecting production efficiency. For intermittent feeding requirements, the traditional method is even more difficult to meet, and it is impossible to flexibly adjust the feeding frequency according to the actual packaging rhythm.

[0004] During the feeding process, the surface of the syringe is often contaminated with impurities such as dust and stains due to contact with the external environment, and traditional feeding equipment does not have effective cleaning measures. If it is directly packaged without cleaning, it will affect the hygienic quality of the syringe and increase the infection risk during use. At the same time, manual wiping is not only inefficient but also difficult to ensure the consistency of the wiping effect.

[0005] In the packaging process, traditional methods are mostly manual packaging or simple mechanical assistance, with slow packaging speed and uneven packaging quality. This not only consumes a large amount of manpower and material resources but also is difficult to meet the growing demand of the medical supplies market. With the continuous improvement of the quality and hygiene standards of syringes in the medical industry and the increasing requirements for production efficiency. In view of the above problems, the present invention provides an automatic syringe packaging machine. Summary of the Invention

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment: As Figure 1 —— Figure 13 shown, an automatic syringe packaging machine includes:

[0035] A base 1, a blanking mechanism, a feeding mechanism, and a packaging mechanism. The blanking mechanism is installed on the base 1. The blanking mechanism includes a storage bin 2 for placing syringes 50 to be packaged. The feeding mechanism is installed on the base 1 and includes two symmetrically arranged cylinders 25 to push the syringe 50. The packaging mechanism is installed on the base 1 and includes a rectangular box 38 fixedly installed on the base 1, and a packaging bag for packaging is placed in the rectangular box 38.

[0036] As Figure 1 , Figure 2 , Figure 5 , Figure 8 , Figure 11 , Figure 13 shown, a plurality of syringes 50 are placed in the storage bin 2, where the rabbet 52 and the cylinder 51 on the syringe 50 are inside the storage bin 2, and the piston rod 53 is outside the storage bin 2. During the blanking process, the syringe 50 slides down along the T-shaped groove 3 on the storage bin 2. After the syringe 50 leaves the storage bin 2, it is pushed by the cylinder 25 in the feeding mechanism towards the side where the packaging mechanism is located, and finally, the packaging is completed through the packaging bag placed inside the rectangular box 38 in the packaging mechanism.

[0037] The blanking mechanism further includes two blanking disks 4 arranged along the depth direction of the storage bin 2. The blanking disks 4 are rotatably installed on the storage bin 2. The two blanking disks 4 are connected by a belt assembly 5. The lower blanking disk 4 is fixedly connected coaxially with a gear 6. The gear 6 is meshed and cooperated with a gear 7. When the two blanking disks 4 rotate, the push rods on the blanking disks 4 push the syringes placed in the storage bin 2 downward along the T-shaped groove 3 on the storage bin 2.

[0038] As Figures 1 to 6 shown, when the gear 7 rotates, the gear 6 meshed and cooperated with the gear 7 will rotate, causing the lower blanking disk 4 fixedly connected coaxially with the gear 6 to rotate, so that the lower blanking disk 4 drives the upper blanking disk 4 to rotate counterclockwise (from the perspective of Figure 3 ), and the push rods on the blanking disks 4 will push the syringe 50 downward through the part between the ball head rod 43 and the rabbet 52.

[0039] The blanking mechanism further includes a double-shaft motor 8 fixedly installed on the storage bin 2. One output shaft of the double-shaft motor 8 is fixedly connected to the second gear 7, and the other output shaft of the double-shaft motor 8 is fixedly connected to one end of a bidirectional lead screw 9. The other end of the bidirectional lead screw 9 is rotatably installed on the storage bin 2. The bidirectional lead screw 9 forms a threaded fit with one end of a moving rod 10. The other end of the moving rod 10 is rotatably connected to an extrusion rod 14. A sliding rod 11 is fixedly installed on the moving rod 10. The sliding rod 11 is slidably fitted with a guide groove 13 on a guide rod 12. The guide rod 12 is fixedly installed on the storage bin 2. Two circular holes 15 are provided on the extrusion rod 14. The circular holes 15 are slidably fitted with a round bar 17 fixedly installed on the storage bin 2. One end of the extrusion rod 14 near the circular holes 15 is fixedly connected to an extrusion plate 16. A first return spring 18 is provided on the outer ring of the round bar 17. One end of the first return spring 18 is fixedly connected to the round bar 17, and the other end of the first return spring 18 is fixedly connected to the extrusion plate 16.

[0040] As Figures 1 to 7 shown, the second gear 7 is fixedly installed on one output shaft of the double-shaft motor 8. So when the double-shaft motor 8 is started, the second gear 7 will rotate. Similarly, the bidirectional lead screw 9 fixedly connected to the other output shaft of the double-shaft motor 8 will rotate on the storage bin 2. The bidirectional lead screw 9 forms a threaded fit with the moving rod 10. So during the rotation of the bidirectional lead screw 9, the moving rod 10 will drive the sliding rod 11 to slide on the guide groove 13. Since the bidirectional lead screw 9 is provided with a bidirectional thread, the moving rod 10 will perform a reciprocating linear movement on the bidirectional lead screw 9, that is, the moving rod 10 drives the extrusion rod 14 and the sliding rod 11 to perform a reciprocating linear movement. When the moving rod 10 drives the extrusion rod 14 to move, the circular holes 15 on the extrusion rod 14 move reciprocally along the round bar 17, so that the extrusion rod 14 drives the extrusion plate 16 to move reciprocally. The purpose of this is to reciprocally make the extrusion plate 16 extrude the piston rod 53, so that the piston rod 53 discharges the residual air inside the cylinder 51. In this process, the function of the first return spring 18 is to assist the extrusion rod 14 and the extrusion plate 16 to reset.

[0041] The blanking mechanism further includes a flip door 24. The flip door 24 is rotatably installed below the storage bin 2. A third gear 23 is fixedly installed on the shaft where the flip door 24 is located. The third gear 23 is engaged with a rack 22. The rack 22 is fixedly connected to a flat plate 19. The flat plate 19 is slidably installed on a first vertical rod 20. The first vertical rod 20 is fixedly installed on the storage bin 2. And a second return spring 21 is provided between the first vertical rod 20 and the storage bin 2. The second return spring 21 is sleeved on the outer ring of the first vertical rod 20.

[0042] As Figure 1 、 Figure 3 、As Figure 5 and Figure 6As shown in the figure, when the lower material tray 4 located below rotates, the lever arranged circumferentially on the lower material tray 4 will alternately fluctuate the flat plate 19 upward, causing the flat plate 19 to slide upward along the vertical rod 20. When the lever leaves the flat plate 19, under the action of the return spring 21, the flat plate 19 will slide downward along the vertical rod 20 to reset. The purpose of doing this is that when the flat plate 19 slides, the flat plate 19 will drive the rack 22 to move up and down, so that the gear 23 meshing with the rack 22 drives the flip door 24 to rotate. When the flip door 24 rotates to a sufficient space appears below the storage box 2, the syringe 50 in the storage box 2 will slide out of the storage box 2, thus completing one material feeding. Through the reciprocating up and down movement of the flat plate 19, intermittent material feeding can be achieved.

[0043] The feeding mechanism further includes two brackets 26, and the two brackets 26 are respectively installed on the extending ends of the two cylinders 25. A ball head rod 27 and an electric cylinder 28 are fixedly installed on the bracket 26, and a clamping plate 29 is fixedly installed on the extending end of the electric cylinder 28.

[0044] As Figure 8 、 Figure 9 、 Figure 13 shown, when the syringe 50 falls from the storage box 2, the right side of the rabbet 52 (taking Figure 13 the perspective as the standard) contacts the right side of the ball head rod 27 (taking Figure 9 the perspective as the standard). At the same time, the electric cylinder 28 is started, so that the extending end of the electric cylinder 28 drives the clamping plate 29 to approach the piston rod 53, and finally the two clamping plates 29 clamp the area between the piston rod 53 and the rabbet 52. Then the cylinder 25 is started, and the bracket 26 and the syringe 50 are driven by the cylinder 25 to move toward the side close to the upper ring 34 and the lower ring 35.

[0045] The feeding mechanism further includes an upper frame 30 and a lower frame 32. Two symmetrically arranged inclined planes 31 are provided on the upper frame 30. The upper frame 30 is fixedly installed with a vertical rod 36 and an upper ring 34. The vertical rod 36 is slidably matched with the base 1, and a return spring 37 is arranged between the vertical rod 36 and the base 1. Two symmetrically arranged inclined planes 33 are provided on the lower frame 32. A lower ring 35 is provided on the lower frame 32. The lower ring 35 is directly below the upper ring 34. The lower frame 32 is slidably matched with the U-shaped frame 48 fixedly installed below the base 1. A return spring 49 is arranged between the lower frame 32 and the rectangular box 38.

[0046] As Figure 8 、 Figure 9 、 Figure 10 、 Figure 13As shown, when the first ball head rod 27 moves towards the side close to the upper frame 30, first, the cylindrical part 51 in the syringe 50 will contact the lower ring 35 and the upper ring 34 that are in contact with each other. The surface of the cylinder 51 is wiped by the upper ring 34 and the first cylinder 25 to remove the dust remaining on the surface of the cylinder 51. Then, as the first ball head rod 27 moves, both ends of the first ball head rod 27 will respectively contact the upper frame 30 and the lower frame 32. At this time, both ends of the first ball head rod 27 slide relative to the first inclined surface 31 and the lower frame 32, so that the upper frame 30 is pushed upward and the lower frame 32 is pushed downward by the first ball head rod 27. During this process, the third return spring 37 will be compressed, and the fifth return spring 49 will be compressed during the downward movement of the lower frame 32. The functions of the third return spring 37 and the fifth return spring 49 are to assist the reset of the upper ring 34 and the lower ring 35. After the upper ring 34 and the lower ring 35 move away, the stop 52 in the syringe 50 passes through the upper ring 34 and the lower ring 35. The first inclined surfaces 31 are provided on both sides of the upper frame 30, and the second inclined surfaces 33 are provided on both sides of the lower frame 32 in the same way. The purpose of this is to ensure that when the first ball head rod 27 moves towards the side close to the storage box 2, it can still pass through the upper ring 34 and the lower ring 35 smoothly.

[0047] The packaging mechanism further includes a second cylinder 39. The second cylinder 39 is fixedly installed on the base 1, and the extending end of the second cylinder 39 is fixedly installed with a feeding plate 40. The feeding plate 40 is slidably matched with the discharge slot on the rectangular box 38.

[0048] As Figure 1 、 Figure 2 、 Figure 11 、 Figure 13 As shown, when packaging the syringe 50, the second cylinder 39 is started, so that the extending end of the second cylinder 39 pushes the feeding plate 40 to slide along the rectangular box 38, and moves the packaging bag in the rectangular box 38 towards the side where the first ball head rod 27 conveys the syringe 50 (when the packaging bag comes out of the rectangular box 38, the side close to the syringe 50 to be packaged is open). The feeding plate 40 pushes the packaging bag to the front of the syringe 50. In this way, when the first ball head rod 27 conveys the syringe 50, the syringe 50 will be sent into the packaging bag. Then, the open end of the packaging bag can be sealed by means of a manipulator or the like.

[0049] The packaging mechanism includes a push rod 41. The extending end of the second cylinder 39 is fixedly connected to the push rod 41. A sliding block 44 is fixedly installed on the push rod 41. The sliding block 44 is slidably matched with the rectangular box 38. A second ball head rod 43 is slidably installed on the sliding block 44. The upper end of the second ball head rod 43 is slidably matched with the third inclined surface provided on the wedge block 42. The wedge block 42 is fixedly installed on the rectangular box 38. And a fourth return spring 45 is sleeved on one end of the second ball head rod 43 close to the wedge block 42. One end of the fourth return spring 45 is fixedly connected to the second ball head rod 43, and the other end of the fourth return spring 45 is fixedly connected to the sliding block 44. The lower end of the second ball head rod 43 is slidably matched with the pressing plate 46. The pressing plate 46 is fixedly connected to the rotating shaft 47. The rotating shaft 47 is rotatably installed on the base 1. And a coil spring is sleeved outside the rotating shaft 47. The coil spring is connected to the base 1.

[0050] As Figure 11 and Figure 12 shown, when the second cylinder 39 pushes the feeding plate 40 to move, the push rod 41 fixedly connected to the extending end of the second cylinder 39 will also move. The push rod 41 drives the sliding block 44 to slide on the rectangular box 38. The upper end of the sliding block 44 moves along the third inclined surface on the wedge block 42. The second ball head rod 43 gradually slides downward on the sliding block 44. When the lower end of the second ball head rod 43 touches the pressing plate 46, it will press down the pressing plate 46 that was originally in a horizontal state. During this process, the rotating shaft 47 fixedly connected to the pressing plate 46 will rotate on the base 1, and at the same time, the coil spring will generate elastic force. The function of the coil spring is to assist the reset of the pressing plate 46. When the pressing plate 46 is pushed by the second ball head rod 43 to rotate, the lowered end of the pressing plate 46 will touch the packaging bag. The purpose of this is to fix the packaging bag through the pressing plate 46 to prevent the packaging bag from shifting during the process of the syringe 50 entering the packaging bag, which affects the packaging quality.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; under the idea of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.
