Description

Technical Field

[0001] This invention belongs to the field of injection manufacturing technology, and particularly relates to an injection filling device. Background Technology

[0002] Injectable drugs act rapidly and reliably, are unaffected by pH, enzymes, or food, have no first-pass effect, and can exert systemic or localized effects. They are suitable for patients who cannot take oral medications. However, the development and production process of injectable drugs is complex, their safety and adaptability to the body are poor, and their cost is high. Currently, the processing and production of injectable drugs requires bottling and filling, necessitating the use of filling equipment. This equipment can inject a fixed amount of injectable drug into the filling bottle, and the positioning and conveying of the filling bottle can also be automated.

[0003] However, existing filling equipment for injectable drugs still has certain problems: 1. After filling, when the filling head is pulled out of the filling bottle, there will be droplets of injectable solution adhering to the bottom of the filling tube. As the filling head and the filling bottle move, the injectable solution will drip onto the outside of the filling bottle; 2. Before the filling head is inserted into the filling bottle, the filling bottle will inevitably shake, which poses a risk of collision between the filling head and the filling bottle. Summary of the Invention

[0004] The purpose of this invention is to provide an injection filling device to solve the above-mentioned problems, so as to avoid the injection liquid from dripping from the filling tube during the injection filling process and to ensure that the filling tube is relatively stationary before it is inserted into the filling bottle.

Two sets of electromagnets are fixedly connected to the tube wall of the filling tube, and the two sets of electromagnets are respectively provided corresponding to the two sets of opening and closing blocks.

[0011] Preferably, the smaller diameter end of the semi-conical hole is located at the top of the opening and closing block, and the larger diameter end of the semi-conical hole is located at the bottom of the opening and closing block.

[0012] Preferably, a sealing cap is slidably fitted at the bottom of the filling tube, and one end of a second spring is fixedly connected to the top of the sealing cap. The second spring is slidably fitted on the filling tube, and the other end of the second spring is fixedly connected to the filling tube.

[0013] Preferably, the clamping member includes a plurality of first cylinders horizontally fixedly connected within the first fixed seat, the extension and retraction directions of the plurality of first cylinders being perpendicular to the conveying direction of the conveyor belt, and a baffle being fixedly connected to the extension and retraction ends of the plurality of first cylinders, the baffle being used to clamp the filling bottle between the second fixed seat and the baffle.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-6 The present invention provides an injection filling device, comprising:

[0028] The filling machine body 1 is provided with a plurality of filling tubes 17. The top of the filling tube 17 is provided with a liquid inlet channel and a negative pressure channel. The top of the filling tube 17 is also provided with a conversion component. When the conversion component is in the first state, the liquid inlet channel is connected to the inside of the filling tube 17. When the conversion component is in the second state, the negative pressure channel is connected to the inside of the filling tube 17.

[0029] The conveying assembly includes a conveyor belt 9 disposed inside the filling machine body 1. The conveyor belt 9 is used to convey filling bottles. A first fixed seat 5 and a second fixed seat 12 are respectively disposed on both sides of the conveyor belt 9. A clamping member is disposed between the second fixed seat 12 and the first fixed seat 5. The clamping member is used to clamp the filling bottles. A blocking member is disposed on the first fixed seat 5. The blocking member is used to block a certain number of filling bottles between the clamping members.

[0030] The main function of the filling tube 17 is to fill the filling bottle with the injection solution; the inlet channel is connected to the injection solution storage tank; the negative pressure channel is connected to the negative pressure generating device; when the conversion component is in the first state, the injection solution flows into the filling tube 17 through the inlet channel to realize the filling of the injection solution; when the conversion component is in the second state, the negative pressure channel is connected to the inside of the filling tube 17, and the negative pressure generating device keeps the filling tube 17 in a negative pressure state through the negative pressure channel to prevent the residual liquid in the filling tube 17 from dripping downwards; the main function of the conveyor belt 9 is to convey the filling bottle below the filling tube 17 and transport the filled bottle away; the main function of the blocking component is to block an appropriate number of filling bottles below several filling tubes 17 to facilitate the subsequent insertion of the filling tube 17 into the filling bottle; the main function of the clamping component is to clamp the several filling bottles blocked by the blocking component firmly to prevent the filling bottle from shaking. Overall, this invention utilizes the suction effect of negative pressure to prevent droplets adhering to the filling tube from falling due to gravity during the injection filling process, ensuring that no injection liquid drips from the filling tube after filling. At the same time, the pre-clamping of the clamping component ensures that the canning bottle will not shake before the filling tube is inserted into the filling bottle, avoiding collision between the filling tube and the filling bottle and improving filling efficiency.

[0031] The design is further optimized by including a controller to control its electrical connection with the negative pressure generating device, conversion component, conveyor belt 9, clamping component, and blocking component.

[0032] The solution is further optimized. The liquid inlet channel includes a liquid inlet pipe connector 18, which is connected to the top of the filling pipe 17. The negative pressure channel includes a negative pressure branch pipe 23, one end of which is connected to the top of the side wall of the filling pipe 17. A negative pressure pipe connector 19 is connected to the side wall of the negative pressure branch pipe 23. The conversion component is set between the negative pressure branch pipe 23 and the filling pipe 17.

[0033] like Figure 4 and Figure 5 As shown, the liquid inlet connector 18 or the negative pressure connector 19 is internally connected to the filling tube 17, and its connection or disconnection is controlled by the conversion component.

[0034] The scheme is further optimized. The conversion component includes a conversion block 20 that is slidably connected between the negative pressure branch pipe 23 and the filling pipe 17. A connecting channel 21 is opened in the conversion block 20. One end of the connecting channel 21 is connected to the negative pressure branch pipe 23, and the other end of the connecting channel 21 is arranged downward and corresponding to the filling pipe 17. The end of the negative pressure branch pipe 23 away from the filling pipe 17 is sealed and fixedly connected to a third cylinder 22. The telescopic end of the third cylinder 22 is fixedly connected to the conversion block 20.

[0035] like Figure 4 As shown, at this time, the conversion block 20 is in the filling state. The medicine in the injection tank is pumped through the inlet pipe joint 18 and the filling pipe 17 and flows out from the bottom of the filling pipe 17 into the filling bottle.

[0036] like Figure 5 As shown, at this time, the conversion block 20 is in a negative pressure suction state. The extension end of the third cylinder 22 drives the conversion block 20 to move into the filling tube 17 and seal the filling tube 17. At this time, the negative pressure generated by the negative pressure generating device is connected to the inside of the filling tube 17 through the negative pressure pipe joint 19, the negative pressure branch pipe 23 and the connecting channel 21, so that the inside of the filling tube 17 is in a negative pressure state. The liquid droplets adhering to the inner wall are suctioned by the negative pressure and will not fall under the action of gravity, thereby avoiding the risk of liquid droplets falling after the filling tube 17 leaves the filling bottle.

[0037] To further optimize the design, a pipe diameter switching assembly is also provided on the side wall of the filling tube 17. The pipe diameter switching assembly includes two sets of opening and closing blocks 24 that are slidably connected inside the filling tube 17. Semi-conical holes 29 are respectively opened on the opposite side walls of the two sets of opening and closing blocks 24. The two sets of opening and closing blocks 24 are closed, and the two sets of semi-conical holes 29 form a frustum-shaped hole. The axis of the frustum-shaped hole coincides with the axis of the filling tube 17. A first spring 25 is abutted between the side of the opening and closing block 24 near the wall of the filling tube 17 and the filling tube 17. Two sets of electromagnets 26 are fixedly connected to the wall of the filling tube 17. The two sets of electromagnets 26 are respectively set to correspond to the two sets of opening and closing blocks 24.

[0038] In a further optimized design, the small-diameter end of the semi-conical hole 29 is located at the top of the opening and closing block 24, and the large-diameter end of the semi-conical hole 29 is located at the bottom of the opening and closing block 24.

[0039] like Figure 5 As shown, when in negative pressure suction state, in order to increase negative pressure airflow and enhance suction effect, the controller controls the two sets of electromagnets 26 to be de-energized, so that the opening and closing block 24 moves towards the middle and fits under the action of the first spring 25. The two sets of semi-conical holes 29 form a frustum-shaped hole. Since the opening at the top of the frustum-shaped hole is small, the airflow will increase significantly, thereby enhancing the suction force below the frustum-shaped hole. This further ensures that the liquid droplets remaining at the bottom of the filling tube 17 will not fall, and can even make the liquid droplets move up along the side wall of the semi-conical hole 29 under the action of negative pressure, completely eliminating the dripping phenomenon.

[0040] like Figure 4 As shown, when the tank is in liquid state, the controller controls the electromagnet 26 to be energized, causing the two opening and closing blocks 24 to move to both sides, reopening the internal flow channel of the filling tube 17 to ensure the filling flow rate.

[0041] In a further optimized design, a sealing cap 28 is slidably fitted at the bottom of the filling tube 17, and one end of a second spring 27 is fixedly connected to the top of the sealing cap 28. The second spring 27 is slidably fitted on the filling tube 17, and the other end of the second spring 27 is fixedly connected to the filling tube 17.

[0042] like Figure 4 As shown, a rubber pad is fixedly connected to the bottom of the sealing cap 28. When the filling tube 17 moves down and extends into the filling bottle, the rubber pad under the sealing cap 28 can fit against the bottle mouth. The pressure of the second spring 27 on the sealing cap 28 can seal the bottle mouth to a certain extent, preventing the medicine and water vapor from spreading out during the filling process.

[0043] In a further optimized design, a fixed plate 14 is fixedly connected inside the filling machine body 1. Several second cylinders 15 are vertically fixedly connected to the fixed plate 14. A bearing plate 16 is fixedly connected between the telescopic ends of the several second cylinders 15. Several filling pipes 17 are vertically fixedly connected to the bearing plate 16.

[0044] like Figure 3 As shown, the main function of the several second cylinders 15 is to change the height of the support plate 16, thereby adjusting the height of the several filling tubes 17, so that the filling tubes 17 can extend into or leave the filling bottle.

[0045] Further optimization of the scheme: the clamping component includes several first cylinders 11 that are horizontally fixedly connected in the first fixed seat 5. The extension and retraction direction of the several first cylinders 11 is perpendicular to the conveying direction of the conveyor belt 9. The extension and retraction ends of the several first cylinders 11 are fixedly connected to baffles 10. The baffles 10 are used to clamp the filling bottles between the second fixed seat 12 and the baffles 10.

[0046] like Figure 1 and Figure 2 As shown, when an appropriate number of bottles are blocked by the blocking component below the filling tube 17, the controller controls the first cylinder 11 to extend, thereby pushing the baffle 10 to move towards the second fixed seat 12, squeezing the bottles between the baffle 10 and the second fixed seat 12, thus clamping and fixing the bottles.

[0047] The scheme is further optimized. The blocking component includes a connecting rod 30 that is horizontally rotatably connected in the second fixed seat 12. The axial direction of the connecting rod 30 is the same as the transmission direction of the conveyor belt 9. The two ends of the connecting rod 30 pass through the side wall of the second fixed seat 12 respectively, and the two ends of the connecting rod 30 are fixedly connected to the blocking plate 13 respectively. The position projections of the two sets of blocking plates 13 coincide along the axial direction of the connecting rod 30. A first gear 31 is fixedly sleeved on the connecting rod 30. A servo motor 8 is fixedly connected in the second fixed seat 12. A second gear 32 is fixedly sleeved on the output shaft of the servo motor 8. The second gear 32 meshes with the first gear 31.

[0048] like Figure 2 , Figure 3 and Figure 6 As shown, the axial length of the connecting rod 30 is greater than the sum of the diameters of the six sets of bottles. During the bottle conveying process, the barrier plate 13 is in a raised state. When the conveyor belt 9 conveys the six sets of bottles past the barrier plate 13 on the left, the controller controls the servo motor 8 to rotate at a certain angle, driving the second gear 32 to rotate and move by an angle. This, in turn, drives the connecting rod 30 to rotate 90 degrees through the first gear 31, moving both sets of barrier plates 13 from below to above the conveyor belt 9. This causes the left barrier plate 13 to block the bottles behind from moving forward, while the right barrier plate 13 blocks the six sets of bottles, preventing them from moving further. The position of the right barrier plate 13 is set to ensure that the bottle mouths of the six sets of bottles correspond one-to-one with the filling tubes 17.

[0049] Then, the controller controls the first cylinder 11 to move, so that the baffle 10 clamps the six sets of filling bottles between the baffle 10 and the second fixed seat 12, thereby fixing the filling bottles. Then, the filling work can be carried out.

[0050] To further optimize the design, limit components are also provided on both sides of the conveyor belt 9. The limit components include two sets of adjustment plates 3 that are fixedly connected to both sides of the conveyor belt 9. Several screws 4 are threadedly connected to the adjustment plates 3. The ends of the screws 4 near the conveyor belt 9 pass through the adjustment plates 3 and are rotatably connected to the connecting blocks 7. Limit rods 6 are horizontally fixedly connected between the connecting blocks 7.

[0051] like Figure 2 As shown, to ensure that the filling bottles can move smoothly between the second fixed seat 12 and the baffle 10, limiting rods 6 are respectively set on both sides of the first fixed seat 5 and the second fixed seat 12. According to the size of the filling bottle, the screw 4 is manually rotated. The movement of the screw 4 on the adjusting plate 3 drives the connecting block 7 to move relative to the adjusting plate 3, thereby realizing the final position adjustment of the limiting rod 6, which guides and limits the movement of the filling bottle on the conveyor belt 9.

[0052] Further optimize the plan, such as Figure 1As shown, the conveyor belt 9 is fixedly connected to the filling machine body 1 via conveyor belt fixing plates 2 on both sides. The first fixing seat 5, the second fixing seat 12, and the adjusting plate 3 are fixedly connected to the two sets of conveyor belt fixing plates 2.

[0054] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
