Description

Technical Field

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

[0002] In the medical device industry, syringes are extremely commonly used products, and their quality is directly related to medical safety and patient health. As a key component of syringes, syringe stoppers play an important role in sealing, preventing drug leakage, and ensuring the stability of drug quality. Therefore, the hygiene of the stoppers must be strictly controlled.

[0003] In the traditional production process of syringe stoppers, the packaging of stoppers is often carried out in a relatively simple environment, lacking an effective disinfection process. After production, the stoppers are usually packaged directly, which may cause the stoppers to be contaminated with dust, microorganisms and other pollutants before packaging. Once these pollutants enter the syringe with the stopper and then come into contact with the liquid medicine, they are likely to contaminate the medicine, causing the medicine to deteriorate, reduce the efficacy and even cause serious medical accidents, threatening the life and health of patients.

[0004] Although some manufacturers have realized the importance of rubber stopper disinfection and have tried to adopt some manual disinfection methods, such as wiping and disinfecting the rubber stoppers one by one before packaging or using simple disinfection equipment for batch disinfection, these methods have obvious disadvantages. The efficiency of manual wiping disinfection is extremely low, and it is difficult to ensure that each rubber stopper can be disinfected evenly and thoroughly, and disinfection dead corners are prone to occur. Simple batch disinfection equipment, due to the lack of precise control and effective connection with the packaging process, not only has an unstable disinfection effect, but may also cause the disinfected rubber stoppers to be contaminated again while waiting for packaging. In response to the above problems, the present invention provides an automatic packaging device for syringe stoppers. Summary of the invention

[0029] Example: Figure 1 —— Fig.12The automatic packaging equipment for syringe plugs shown in the figure comprises: Bracket 1, bracket 1 is rotatably connected with round table 2; A material unloading mechanism, which is mounted on the round table 2; A disinfection mechanism, the disinfection mechanism is connected to the discharge barrel 3, the discharge barrel 3 is fixedly mounted on the bracket 1, and the rubber plug stored in the discharge barrel 3 is disinfected by the disinfection mechanism; The packaging mechanism is connected with the bracket 1 and the round table 2, and is used for packaging the rubber plug.

[0030] like Figure 1 , Figure 3 As shown, the bracket 1 is the installation base, the discharge barrel 3 is fixedly connected to the bracket 1, the lower surface of the discharge barrel 3 is slidably matched with the round table 2, and a collecting box 43 is arranged below the round table 2. The collecting box 43 is used to collect the packaged syringe plugs and packaging bags. The interior of the discharge barrel 3 is equipped with a plurality of plugs to be packaged, and the plugs can be disinfected by a disinfection mechanism. The discharge mechanism will allow the plugs in the discharge barrel 3 to gradually come out of the discharge barrel 3 and complete the packaging through the packaging mechanism.

When the contact switch 2 44 contacts one of the two contact switches 3 arranged circumferentially on the bracket 1, the motor 4 starts to reverse.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, when the output shaft of the motor 14 rotates, the truncated table 2 and the rotating table 5 fixed on the output shaft will move. When the truncated table 2 rotates, when the discharge hole set on the truncated table 2 coincides with the bottom of the discharge barrel 3, the rubber plug in the discharge barrel 3 will fall onto the packaging mechanism. In addition, during the rotation of the truncated table 2, the contact switch 2 44 on the truncated table 2 will contact a contact switch 3, at which time the motor 14 will be controlled to reverse through the control center, and when the contact switch 2 44 reverses to contact another contact switch 3, the motor 14 will reverse again, that is, the motor 14 will drive the truncated table 2 and the rotating table 5 to reverse back and forth. It should be noted that how to control the motor 14 to rotate forward and reverse belongs to the prior art, and those skilled in the art can know and implement it.

[0034] like Figure 1 , Figure 4 , Figure 6 , Figure 7 As shown, when the round table 2 rotates with the rotating table 5, the boss 6 on the rotating table 5 will drive the rectangular plate 17 to move, so that the rectangular plate 17 drives the sliding block 9 to slide back and forth along the rectangular plate 28. In this process, the function of the reset spring 10 is to assist the reset of the sliding block 9. During the reciprocating movement of the sliding block 9, the end of the ball head rod 11 fixedly connected to the sliding block 9 close to the discharge barrel 3 will reciprocate and knock the outer surface of the discharge barrel 3. The purpose of this is to make the discharge barrel 3 vibrate slightly, so that the rubber plug in the discharge barrel 3 can fall smoothly. Of course, when the boss 6 rotates, the boss 6 will also drive the pull rod 12 to move.

[0035] The disinfection mechanism includes a storage barrel 26, which is fixedly mounted on the lower barrel 3. The storage barrel 26 is communicated with the upper piston barrel 24, which is mounted on the lower barrel 3 and connected to the liquid inlet hole above the lower barrel 3.

The upper piston rod 23 is rotatably connected to one end of a rotating rod three 22, and the other end of the rotating rod three 22 is rotatably connected to one end of a moving rod 21. The moving rod 21 is slidably mounted on a rectangular plate three 20, which is fixedly mounted on the lower barrel 3, and a return spring four is arranged between the moving rod 21 and the rectangular plate three 20.

[0036] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, when the rotating rod 3 22 drives the upper piston rod 23 to slide back and forth along the upper piston barrel 24, the medical alcohol stored in the storage barrel 26 can intermittently enter the upper piston barrel 24, and the alcohol entering the upper piston barrel 24 is pushed into the lower barrel 3 by the upper piston rod 23 to sterilize the rubber plug in the lower barrel 3. When the moving rod 21 slides along the rectangular plate 3 20, it can drive the rotating rod 3 22 to swing, thereby driving the upper piston rod 23 to move. The function of the reset spring 4 is to assist the reset of the moving rod 21, and the function of the rectangular plate 3 20 is to guide the rectangular plate 3 20.

[0037] The disinfection mechanism also includes a collecting barrel 25, which is fixedly mounted on the lower material barrel 3. A lower piston barrel 14 is connected to the collecting barrel 25. The lower piston barrel 14 is fixedly mounted on the lower material barrel 3, and the lower piston barrel 14 is connected to the liquid outlet below the lower material barrel 3. The lower piston barrel 14 is slidably matched with the lower piston rod 13.

[0038] like Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, when the pull rod 12 rotates with the boss 6, the pull rod 12 will pull the lower piston rod 13, causing the lower piston rod 13 to move back and forth along the lower piston barrel 14. When the lower piston rod 13 slides to a point where it no longer blocks the connection between the lower piston barrel 14 and the collecting barrel 25, the alcohol extracted from the lower material barrel 3 by the lower piston rod 13 will enter the collecting barrel 25, thereby completing the recovery of the alcohol.

[0039] The connecting rod assembly includes a rotating rod 15, one end of which is rotatably connected to one end of the lower piston rod 13, the other end of which is connected to one end of a rotating rod 2 16, the other end of which is rotatably matched with a connecting rod 17, the other end of the connecting rod 17 is rotatably connected to one end of a rocker rod 18, the rocker rod 18 is rotatably mounted on a rectangular plate 3 20, and a coil spring 19 is provided between the rocker rod 18 and the rectangular plate 3 20, and one end of the rocker rod 18 away from the connecting rod 17 is slidably matched with one end of the moving rod 21 away from the rotating rod 3 22.

[0040] like Figure 1 , Figure 2 , Figure 5 As shown, when the lower piston rod 13 slides back and forth, the lower piston rod 13 drives the rotating rod 15 to swing back and forth, and the rotating rod 15 drives the connecting rod 17 to swing through the rotating rod 2 16, so that the connecting rod 17 drives the swing rod 18 to rotate on the rectangular plate 3 20, and the function of the coil spring 19 is to assist the reset of the swing rod 18. The rotation of the swing rod 18 drives the moving rod 21 to slide back and forth on the rectangular plate 3 20.

[0041] The packaging mechanism includes a long rod 27 fixedly mounted on the bracket 1, a heating plate 30 is slidably mounted on the long rod 27, one end of a guide rod 32 is fixedly mounted on the heating plate 30, the other end of the guide rod 32 is slidably matched with a heating plate 2 31, a return spring 2 33 is arranged between the heating plate 2 31 and the guide rod 32, one end of a pull rod 29 is connected to the heating plate 30, the other end of the pull rod 29 is fixedly connected to the output shaft of a motor 28, and the motor 28 is fixedly mounted on the bracket 1.

[0042] The packaging mechanism includes a ball head rod 2 34, one end of which is fixedly connected to the heating plate 2 31, and a guide block 35 is provided at the end away from the long rod 27. The guide block 35 is fixedly connected to the bracket 1, and two inclined surfaces 36 and a plane 37 are provided on the guide block 35. The plane 37 is located between the two inclined surfaces 36, and a contact switch 1 38 is provided on the guide block 35.

[0043] The packaging mechanism also includes a flip shell 40, which is rotatably connected to the heating plate 31. A stopper 41 is fixedly installed on the flip shell 40, and a coil spring 42 is arranged between the flip shell 40 and the heating plate 31.

One end of the push rod 39 is fixedly installed on the guide block 35, and the other end of the push rod 39 is located in front of the plane 37.

[0044] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 As shown, when the motor 28 is started, the output shaft of the motor 28 drives the pull rod 29 to rotate, thereby pulling the heating plate 1 30 through the pull rod 29 to perform reciprocating linear motion on the long rod 27. When the rubber plug is packaged, the bag for packaging is placed on the flip shell 40 by a device with a clamping and transferring function such as a manipulator. In the process of heating plate 1 30 driving heating plate 2 31 to move, when the ball head rod 2 34 on heating plate 2 31 contacts the inclined surface 36 close to motor 2 28, the ball head rod 2 34 will slide along the inclined surface 36, so that the ball head rod 2 34 pushes heating plate 2 31 to move to the side close to heating plate 1 30. When heating plate 2 31 contacts heating plate 1 30, the ball head rod 2 34 slides along the inclined surface 36 to the guide block 35 and contacts the contact switch 1 38 on the guide block 35. At this time, by heating heating plate 1 30 and heating plate 2 31, heating plate 1 30 and heating plate 2 31 complete the sealing of the rubber plug that falls into the packaging bag from the discharge barrel 3, that is, heating plate 1 30 and heating plate 2 31 heat-seal the packaging bag to complete the packaging of the rubber plug. After the heat sealing is completed, the ball head rod 34 will slide along the guide block 35. At this time, the stopper 41 will contact one end of the push rod 39. The push rod 39 pushes the stopper 41, so that the stopper 41 drives the flip shell 40 to flip on the heating plate 31, so that the rubber plugs and packaging bags on the flip shell 40 are dropped into the collection box 43 for collection.
