Description

Technical Field

[0001] The invention belongs to the technical field of packaging equipment, and in particular relates to an automatic packaging machine for syringes. Background Art

[0002] In the field of medical supplies production, syringes are commonly used medical devices, and their production and packaging process is crucial. Traditional syringe packaging methods mostly rely on manual operation or simple semi-automatic equipment, which has many disadvantages. In the process of syringe feeding, continuous feeding was often used in the past, which made it difficult to accurately control the feeding quantity, resulting in material waste or inaccurate packaging quantity. In addition, manual feeding is slow and labor-intensive, which seriously affects production efficiency. For intermittent feeding needs, 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. During the feeding process, the surface of the syringe is often contaminated with dust, stains and other impurities due to contact with the external environment, and traditional feeding equipment does not have effective cleaning measures. If the syringe is directly packaged without cleaning, it will affect the sanitary quality of the syringe and increase the risk of infection during use. At the same time, manual wiping is not only inefficient, but also difficult to ensure the consistency of the wiping effect. 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 lot of manpower and material resources, but also makes it difficult to meet the growing market demand for medical supplies.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example: Figure 1 —— Fig.13 The automatic syringe packaging machine shown comprises: A base 1, a material unloading mechanism, a feeding mechanism, and a packaging mechanism. The material unloading mechanism is installed on the base 1, and the material unloading mechanism includes a storage box 2, and the storage box 2 is used to place the syringes 50 to be packaged; the feeding mechanism is installed on the base 1, and the feeding mechanism includes two symmetrically arranged cylinders 25, and the syringes 50 are pushed by the cylinders 25; the packaging mechanism is installed on the base 1, and the packaging mechanism includes a rectangular box 38 fixedly installed on the base 1, and the packaging bag for packaging is placed in the rectangular box 38.

[0028] like Figure 1 , Figure 2 , Figure 5 , Figure 8 , Fig.11 , Fig.13 As shown, a plurality of syringes 50 are placed in the material storage box 2, wherein the stopper 52 and the cylinder 51 on the syringe 50 are located inside the material storage box 2, and the piston rod 53 is located outside the material storage box 2. During the material discharge process, the syringe 50 slides downward along the T-slot 3 on the material storage box 2; after the syringe 50 leaves the material storage box 2, it is pushed toward the side where the packaging mechanism is located by the cylinder 25 in the feeding mechanism, and finally the packaging is completed through the packaging bag placed inside the rectangular box 38 in the packaging mechanism.

[0029] The unloading mechanism also includes two unloading trays 4 arranged along the depth direction of the storage box 2. The unloading trays 4 are rotatably installed on the storage box 2. The two unloading trays 4 are connected by a belt assembly 5. The unloading tray 4 located below is coaxially fixedly connected with gear 1 6. Gear 1 6 is meshed with gear 2 7. When the two unloading trays 4 rotate, the lever on the unloading tray 4 pushes the syringe placed in the storage box 2 downward along the T-slot 3 on the storage box 2.

[0030] like Figures 1 to 6 As shown, when the gear 2 7 rotates, the gear 1 6 meshing with the gear 2 7 will rotate, so that the lower material tray 4 coaxially connected with the gear 1 6 and located below rotates, so that the lower material tray 4 drives the upper material tray 4 to rotate counterclockwise (with the belt assembly 5) together. Figure 3 The lever on the unloading tray 4 will push the syringe 50 downward through the portion between the ball head rod 43 and the stop 52 when the unloading tray 4 is rotated.

[0031] The unloading mechanism also includes a double-axis motor 8 fixedly mounted on the storage box 2, an output shaft of the double-axis motor 8 is fixedly connected to the gear 2 7, the other output shaft of the double-axis motor 8 is fixedly connected to one end of the bidirectional screw rod 9, the other end of the bidirectional screw rod 9 is rotatably mounted on the storage box 2, the bidirectional screw rod 9 forms a threaded fit with one end of the moving rod 10, the other end of the moving rod 10 is rotatably connected to the extrusion rod 14, and a sliding rod 11 is fixedly mounted on the moving rod 10, the sliding rod 11 is slidably matched with the guide groove 13 on the guide rod 12, the guide rod 12 is fixedly mounted on the storage box 2, two circular holes 15 are provided on the extrusion rod 14, the circular hole 15 is slidably matched with a round rod 17 fixedly mounted on the storage box 2, one end of the extrusion rod 14 close to the circular hole 15 is fixedly connected to the extrusion plate 16, the outer ring of the round rod 17 is provided with a return spring 18, one end of the return spring 18 is fixedly connected to the round rod 17, and the other end of the return spring 18 is fixedly connected to the extrusion plate 16.

[0032] like Figures 1 to 7 As shown, gear 2 7 is fixedly mounted on an output shaft of the dual-axis motor 8, so when the dual-axis motor 8 is started, gear 2 7 will rotate. Similarly, the bidirectional screw rod 9 fixedly connected to the other output shaft of the dual-axis motor 8 will rotate on the storage box 2. The bidirectional screw rod 9 forms a threaded fit with the moving rod 10. Therefore, during the rotation of the bidirectional screw rod 9, the moving rod 10 will drive the sliding rod 11 to slide on the guide groove 13. Since the bidirectional screw rod 9 is provided with a bidirectional thread, the moving rod 10 will reciprocate on the bidirectional screw rod 9. The moving rod 10 drives the extrusion rod 14 and the sliding rod 11 to move linearly, that is, the moving rod 10 drives the extrusion rod 14 and the sliding rod 11 to move linearly back and forth. When the moving rod 10 drives the extrusion rod 14 to move, the round hole 15 on the extrusion rod 14 moves back and forth along the round rod 17, so that the extrusion rod 14 drives the extrusion plate 16 to move back and forth. The purpose of this is to reciprocately squeeze the extrusion plate 16 to squeeze the piston rod 53 so that the piston rod 53 can discharge the residual air inside the cylinder 51. In this process, the role of the reset spring 18 is to assist the reset of the extrusion rod 14 and the extrusion plate 16.

[0033] The unloading mechanism also includes a flip door 24, which is rotatably installed under the storage box 2. A gear 3 23 is fixedly installed on the shaft where the flip door 24 is located. The gear 3 23 is meshed with a rack 22. The rack 22 is fixedly connected to the flat plate 19. The flat plate 19 is slidably installed on a vertical rod 20. The vertical rod 20 is fixedly installed on the storage box 2, and a return spring 21 is arranged between the vertical rod 20 and the storage box 2. The return spring 21 is sleeved on the outer ring of the vertical rod 20.

[0034] like Figure 1 , Figure 3 ,like Figure 5 and Figure 6As shown, when the feeding tray 4 located below rotates, the levers arranged circumferentially on the feeding tray 4 will alternately swing the flat plate 19 upwards, so that the flat plate 19 slides upwards along the vertical rod 1 20. When the lever leaves the flat plate 19, under the action of the reset spring 21, the flat plate 19 will slide downwards along the vertical rod 1 20 to reset. The purpose of 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 3 23 meshing with the rack 22 drives the flip door 24 to rotate. When the flip door 24 rotates to a sufficient space below the storage box 2, the syringe 50 in the storage box 2 will slide out of the storage box 2, thereby completing one feeding. Intermittent feeding can be achieved by the reciprocating up and down movement of the flat plate 19.

[0035] The feeding mechanism also includes two brackets 26, which are respectively installed on the protruding ends of the two cylinders 25. A ball head rod 27 and an electric cylinder 28 are fixedly installed on the brackets 26, and a clamping plate 29 is fixedly installed on the protruding end of the electric cylinder 28.

[0036] like Figure 8 , Fig. 9 , Fig.13 As shown, when the syringe 50 falls from the storage box 2, the right side of the stopper 52 (with Fig.13 The right side of the ball head rod 27 (based on the perspective) is in contact with the ball head rod 27. Fig. 9 The electric cylinder 28 is started at the same time, so that the extended 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 stop 52, and then the cylinder 1 25 is started to drive the bracket 26 and the syringe 50 to move to the side close to the upper ring 34 and the lower ring 35.

[0037] The feeding mechanism also includes an upper frame 30 and a lower frame 32. The upper frame 30 is provided with two symmetrically arranged inclined surfaces 31. The upper frame 30 is fixedly installed with a vertical rod 2 36 and an upper ring 34. The vertical rod 2 36 is slidably matched with the base 1, and a return spring 37 is provided between the vertical rod 2 36 and the base 1. The lower frame 32 is provided with two symmetrically arranged inclined surfaces 33. The lower frame 32 is provided with a lower ring 35, and the lower ring 35 is located directly below the upper ring 34. The lower frame 32 is slidably matched with a U-shaped frame 48 fixedly installed below the base 1, and a return spring 5 49 is provided between the lower frame 32 and the rectangular box 38.

[0038] like Figure 8 , Fig. 9 , Fig.10 , Fig.13As shown, when the ball head rod 27 moves toward the side close to the upper frame 30, the cylinder 51 in the syringe 50 first contacts the lower ring 35 and the upper ring 34 that contact each other, and the surface of the cylinder 51 is wiped by the upper ring 34 and the cylinder 25 to remove the dust remaining on the surface of the cylinder 51. Then, as the ball head rod 27 moves, the two ends of the ball head rod 27 contact the upper frame 30 and the lower frame 32 respectively. At this time, the two ends of the ball head rod 27 are relative to the inclined surface 35. 1 and the lower frame 32 slide, so that the upper frame 30 is pushed upward and the lower frame 32 is pushed downward by the ball head rod 1 27. In this process, the return spring 37 will be compressed, and the return spring 5 49 will be compressed during the downward movement of the lower frame 32. The function of the return spring 37 and the return spring 5 49 is to assist the upper ring 34 and the lower ring 35 to reset. After the upper ring 34 and the lower ring 35 are separated, the stop 52 in the syringe 50 passes through the upper ring 34 and the lower ring 35. The upper frame 30 is provided with inclined planes 1 31 on both sides, and the lower frame 32 is also provided with inclined planes 2 33 on both sides. The purpose of this is that when the ball head rod 1 27 moves to the side close to the storage box 2, it can still pass through the upper ring 34 and the lower ring 35 smoothly.

[0039] The packaging mechanism also includes a second cylinder 39, which is fixedly mounted on the base 1. A feeding plate 40 is fixedly mounted on the protruding end of the second cylinder 39, and the feeding plate 40 is slidably matched with the discharge trough on the rectangular box 38.

[0040] like Figure 1 , Figure 2 , Fig.11 , Fig.13 As shown, when the syringe 50 is packaged, the air cylinder 2 39 is started, so that the extended end of the air cylinder 2 39 pushes the feeding plate 40 to slide along the rectangular box 38, and moves the packaging bag in the rectangular box 38 to the side close to the ball head rod 1 27 to transport 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), and the feeding plate 40 pushes the packaging bag to the front of the syringe 50, so that when the ball head rod 1 27 transports 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 a robot or the like.

[0041] The packaging mechanism includes a push rod 41, the protruding end of the cylinder 2 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 ball head rod 2 43 is slidably installed on the sliding block 44, the upper end of the ball head rod 2 43 is slidably matched with the inclined surface 3 set on the wedge block 42, the wedge block 42 is fixedly installed on the rectangular box 38, and a return spring 45 is sleeved on one end of the ball head rod 2 43 close to the wedge block 42, one end of the return spring 45 is fixedly connected to the ball head rod 2 43, and the other end of the return spring 45 is fixedly connected to the sliding block 44, the lower end of the ball head rod 2 43 is slidably matched with the pressure plate 46, the pressure plate 46 is fixedly connected to the rotating shaft 47, the rotating shaft 47 is rotatably installed on the base 1, and the outer ring of the rotating shaft 47 is sleeved with a coil spring, which is connected to the base 1.

[0042] like Fig.11 and Fig.12 As shown, when the cylinder 2 39 pushes the feeding plate 40 to move, the pushing rod 41 fixedly connected to the protruding end of the cylinder 2 39 will also move, and the pushing rod 41 drives the sliding block 44 to slide on the rectangular box 38, and the upper end of the sliding block 44 moves along the inclined surface 3 on the wedge block 42, and the ball head rod 2 43 gradually slides downward on the sliding block 44. When the lower end of the ball head rod 2 43 contacts the pressure plate 46, it will press the pressure plate 46 which was originally in a horizontal state downward. In this process, the rotating shaft 47 fixedly connected to the pressure 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 pressure plate 46. When the pressure plate 46 is pushed to rotate by the ball head rod 2 43, the lowered end of the pressure plate 46 will contact the packaging bag. The purpose of this is to fix the packaging bag by the pressure plate 46 to prevent the packaging bag from being offset during the process of the syringe 50 entering the packaging bag, thereby affecting the quality of the packaging.
