Abstract
Description
Technical Field
[0001] This invention belongs to the field of filling equipment, and more specifically, it is a filling equipment for the production of dopamine hydrochloride. Background Technology
[0002] The filling equipment for the production of dopamine hydrochloride is a device used in the filling and processing of dopamine hydrochloride solution to fill, heat melt and seal ampoules used to hold dopamine hydrochloride solution. It is mainly composed of three parts: a conveying device, a filling device and a heat melt sealing device.
[0003] Patent document CN116409741A discloses a filling device for the production of dopamine hydrochloride, including a fixed base, a sealing machine, and a filling machine. The sealing machine and the filling machine are both fixedly installed on the upper outer surface of the fixed base. The sealing machine is located on one side of the filling machine. The front end of the sealing machine and the filling machine is provided with a conveying component for conveying ampoules. The conveying component includes two sets of fixed card holders and two sets of movable card holders. The two sets of movable card holders are movably installed inside the two sets of fixed card holders. It can complete the filling and sealing operation of multiple ampoules containing dopamine hydrochloride solution at one time, thereby effectively improving the ampoule sealing efficiency of the filling device, preventing the ampoules from tilting to both sides, and preventing the dopamine hydrochloride solution from spilling out.
[0004] The aforementioned equipment has certain shortcomings in the filling operation of dopamine hydrochloride solution. When filling multiple ampoules simultaneously, misalignment of the bottle necks during the filling process can easily occur, causing dopamine hydrochloride to spill out. Furthermore, simultaneous filling of multiple bottles is prone to errors, reducing the filling effect. Secondly, the equipment uses a clamping structure to seal the ampoules after heat fusion, requiring a halt to the conveying process during sealing, resulting in low efficiency. It also lacks a continuous sealing structure, making it impossible to complete the sealing operation synchronously during ampoule conveying. Additionally, during the filling and sealing operation of dopamine hydrochloride solution, some glass waste is generated after sealing the ampoule necks. The equipment lacks a waste cleaning structure, causing residual waste to affect subsequent sealing operations and reducing its stability during use. Summary of the Invention
[0005] The purpose of this invention is to provide a filling device for the production of dopamine hydrochloride, which can solve the existing problems.
[0006] The problem solved by this invention is:
[0007] 1. When it fills multiple ampoules at the same time, misalignment of the bottle mouths is likely to occur during the filling operation, which makes it easy for dopamine hydrochloride to spill out. At the same time, errors are likely to occur when filling multiple bottles simultaneously, which reduces the filling effect.
[0008] 2. Secondly, the above-mentioned equipment uses a clamp structure to seal the ampoules after hot melting. The sealing operation requires stopping the conveying, which is inefficient. It does not have a continuous sealing structure and cannot complete the sealing operation simultaneously during the ampoule conveying process.
[0009] 3. At the same time, during the filling and sealing operation of dopamine hydrochloride solution, some glass waste will be generated after the ampoule mouth is sealed. The above-mentioned equipment does not have a waste cleaning structure, so the waste residue will affect the subsequent sealing operation and reduce its stability during use.
[0010] The objective of this invention can be achieved through the following technical solutions:
[0011] A filling device for producing dopamine hydrochloride includes a sealing component, a heater, a filling rack, and a fixed base. The heater is fixedly installed on the upper outer surface of the fixed base. The sealing component is located on one side of the heater, and the filling rack is located on the other side of the heater. A filling device is movably installed on the inner side of the filling rack. The filling device includes a positioning plate, a lifting pressure plate, and a connecting plate. The lifting pressure plate is movably installed on the upper part of the connecting plate. Several sets of injection pumps are arranged between the lifting pressure plate and the connecting plate. The positioning plate is fixedly installed on the lower part of the connecting plate. A first cutting plate is movably installed on the inner side of the sealing component. A second cutting plate is movably installed on the upper part of the first cutting plate. The first and second cutting plates are perpendicularly tangent to each other. Both the first and second cutting plates have arc-shaped cuts on their sides.
[0012] As a further technical solution of the present invention, the upper middle position of the lifting pressure plate is driven by a hydraulic rod, and the lifting pressure plate and the connecting plate are elastically connected by a spring rod. A piston rod for use with the injector is fixedly installed at the lower end of the lifting pressure plate. When the hydraulic rod drives the lifting pressure plate to move downward, the calibration plate passes through the ampoule and adjusts its filling position. At the same time, the calibration plate contacts the bottom top rod, so that the calibration plate is in the corresponding position. At this time, under the influence of the spring rod, the lifting pressure plate continues to move downward. The lifting pressure plate squeezes the piston rod, so that several sets of injectors can complete the quantitative delivery at the same time. With the help of the needle structure at the bottom of the injector, the dopamine hydrochloride solution is injected into the ampoule. After the injection is completed, the lifting pressure plate drives the injector to move upward. The spring rod drives the lifting pressure plate and the connecting plate to separate, thereby resetting the piston rod.
[0013] As a further technical solution of the present invention, limiting rods are provided at the four corners of the upper end of the lifting pressure plate, and several sets of elastic clamps are movably installed on the inner side of the calibration plate. The outer surface of one end of the elastic clamp is an arc-shaped groove structure. When the filling device performs the filling operation, the two sets of elastic clamps can respectively clamp and fix the two sides of the ampoule, so as to prevent it from tilting during filling and improve its filling accuracy.
[0014] As a further technical solution of the present invention, the surfaces of several sets of injectors are connected by infusion pipes, and the several sets of infusion pipes are distributed vertically. The injectors on both sides are respectively equipped with inlet pipes and outlet pipes. Solenoid valves are installed at the ends of the inlet pipes and outlet pipes. The raw material tank pumps the dopamine hydrochloride solution into the interior of several sets of injectors in sequence through the inlet pipes and infusion pipes. The vertically distributed infusion pipes can fill several sets of injectors in sequence. When several sets of injectors are filled, the excess dopamine hydrochloride solution will flow back into the interior of the raw material tank through the outlet pipe. By closing the solenoid valves, overflow during injection is prevented, thereby completing the injection operation of several sets of injectors simultaneously.
[0015] As a further technical solution of the present invention, the middle of the first cutting disc and the second cutting disc are both driven by a rotating rod. One end of the rotating rod is provided with a motor, and the other end of the rotating rod is provided with a connecting frame. The connecting frame has an overall T-shaped structure. The connecting frame can play an auxiliary fixing role for the other end of the rotating rod, thereby improving the stability of the first cutting disc and the second cutting disc when rotating. The T-shaped connecting frame facilitates the fixing of the surface of the sealing component.
[0016] As a further technical solution of the present invention, a waste tray is fixedly installed on one side of the sealing component, and a discharge hopper is fixedly installed on the upper part of the waste tray. The discharge hopper is inclined and located below the first cutting disc. A fan is provided on the outer side surface of the sealing component. When the first and second cutting discs perform a rolling cut sealing operation on the hot melt area of the bottle mouth, the cut glass will fall onto the horizontally set first cutting disc, and the glass shards will be discharged into the waste tray for collection through the discharge hopper.
[0017] As a further technical solution of the present invention, a scraper is installed on the upper part of the first cutting disc, and a fan-shaped material outlet is provided on the surface of the first cutting disc. The user drives the rotating rod to rotate by a motor, so that the rotating rod drives the first cutting disc to rotate. When glass slag falls onto the first cutting disc, the scraper can push the glass slag into the fan-shaped material outlet during the rotation of the first cutting disc, and then let it fall down into the discharge hopper through the fan-shaped material outlet.
[0018] As a further technical solution of the present invention, an arc-shaped scraper is fixedly installed on the outer surface of one end of the scraper, and a scraper head for use with the first cutting disc is provided at the lower part of the arc-shaped scraper. By setting the arc-shaped scraper, it can block the glass slag on the upper part of the first cutting disc when the first cutting disc rotates, so that the glass slag can be scraped into the fan-shaped material outlet. Secondly, the scraper head can clean the arc-shaped groove on the surface of the first cutting disc when the first cutting disc rotates, thereby improving the rolling cutting effect of the first and second cutting discs.
[0019] As a further technical solution of the present invention, the elastic clamp and the positioning plate are movably connected by an elastic rotating shaft, and a roller is movably installed at one end of the elastic clamp. By using the roller, the bottle can be pulled out from between the two sets of elastic clamps when the elastic clamp moves upward.
[0020] As a further technical solution of the present invention, a conveyor belt is provided at the upper middle part of the fixed base, a raw material tank and a gas tank are respectively installed inside the fixed base, and a receiving box is fixedly installed at the output end of the conveyor belt.
[0021] The beneficial effects of this invention are:
[0022] 1. By setting up a filling device and a calibration plate, the filling equipment for the production of dopamine hydrochloride can simultaneously complete the quantitative filling operation of multiple bottles of dopamine hydrochloride solution, avoiding filling errors. At the same time, it can simultaneously correct the filling position of multiple bottles of dopamine hydrochloride solution to prevent tilting and improve filling accuracy.
[0023] During operation, the raw material tank pumps dopamine hydrochloride solution sequentially into several sets of injectors via the inlet and outlet pipes. The outlet pipes, distributed vertically, fill each set of injectors in turn. When several sets of injectors are full, excess dopamine hydrochloride solution flows back into the raw material tank through the outlet pipe, creating a circulating conveying structure between the injectors and the raw material tank. By closing the solenoid valve, overflow during injection is prevented. The hydraulic rod drives the lifting plate downwards, allowing the alignment plate to pass through the ampoule. Two sets of elastic clamps securely hold the ampoule on both sides, preventing tilting during filling. To improve the accuracy of the filling process, the filling position is adjusted, and the calibration plate is brought into contact with the bottom rod, ensuring the calibration plate is in the correct position and preventing it from moving further down. At this time, the lifting plate continues to move down due to the influence of the spring rod. The lifting plate squeezes the piston rod, allowing several sets of injectors to complete the quantitative delivery simultaneously. In conjunction with the needle structure at the bottom of the injector, the dopamine hydrochloride solution is injected into the ampoule. After the injection is completed, the lifting plate moves the injector up, and the spring rod drives the lifting plate and connecting plate to separate, thereby resetting the piston rod for future use. This allows for the simultaneous injection operation of several sets of injectors.
[0024] 2. By setting up a first cutting disc and a second cutting disc, the filling equipment for the production of dopamine hydrochloride has a continuous rolling sealing structure, replacing the traditional clamp sealing structure, thereby improving the working efficiency of the sealing operation.
[0025] In use, the hot-melted ampoules are conveyed to the inside of the sealing component via a conveyor belt. The first and second cutting discs are independently driven by motors to rotate. A connecting frame provides auxiliary fixation to the other end of the rotating rod, improving the stability of the first and second cutting discs during rotation. When the end of the ampoule passes between the first and second cutting discs, the hot-melt section of the ampoule is rolled and cut using the first and second cutting discs. The first and second cutting discs are perpendicularly tangent to each other, and their rotation directions are opposite, ensuring the ampoule... The ampoule can pass between the first and second cutting discs. The arc-shaped cuts of the first and second cutting discs make the end of the ampoule arc-shaped after rolling and cutting. The rolling and cutting between the first and second cutting discs compresses the end of the ampoule, so that the heat-melted part can be sealed quickly. At the same time, excess glass material is removed, so that it falls onto the horizontally set first cutting disc. With the rotation of the first cutting disc, it is discharged. Through the first and second cutting discs, the sealing operation can be completed quickly during the conveying process after the ampoule is heat-melted, which improves the filling and sealing efficiency.
[0026] 3. By setting up a scraper and a discharge hopper, the use of the first cutting disc is optimized when the filling equipment for the production of dopamine hydrochloride is used, so that the surface of the first cutting disc has an auxiliary cleaning structure, which can automatically complete the cleaning operation of glass residue.
[0027] During operation, the user drives the rotating rod to rotate via a motor, which in turn rotates the first cutting disc. When glass shards fall onto the first cutting disc, the scraper pushes the shards into the fan-shaped feed inlet during the rotation of the first cutting disc. The shards then fall downwards into the discharge hopper and are discharged into the waste tray for collection. Furthermore, the scraper head cleans the arc-shaped grooves on the surface of the first cutting disc as it rotates, preventing glass residue from adhering to these grooves and improving the cutting effect of both the first and second cutting discs.

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0038] like Figure 1As shown, a filling device for producing dopamine hydrochloride includes a sealing component 7, a heater 8, a filling rack 10, and a fixed base 1. The heater 8 is fixedly installed on the upper outer surface of the fixed base 1. The sealing component 7 is located on one side of the heater 8, and the filling rack 10 is located on the other side of the heater 8. A filling device 9 is movably installed on the inner side of the filling rack 10. The filling device 9 includes a positioning plate 12, a lifting pressure plate 18, and a connecting plate 19. The lifting pressure plate 18 is movably installed on the upper part of the connecting plate 19. Several [partitions] are arranged between the lifting pressure plate 18 and the connecting plate 19. The injection unit 14 and the calibration plate 12 are fixedly installed on the lower part of the connecting plate 19; the first cutting plate 26 is movably installed on the inner side of the sealing component 7, and the second cutting plate 28 is movably installed on the upper part of the first cutting plate 26. The first cutting plate 26 and the second cutting plate 28 are perpendicularly tangent to each other. The sides of the first cutting plate 26 and the second cutting plate 28 are provided with arc-shaped cuts. The heater 8 is provided with a spray head inside, which is supplied with gas by the gas tank 3. During the movement of the ampoule, the mouth part of the ampoule is sprayed with heat to make the mouth part melt, which facilitates the subsequent sealing operation.
[0039] To solve the problem of multiple-bottle quantitative filling during its filling operation, such as Figure 2 As shown, the upper middle part of the lifting plate 18 is driven by the hydraulic rod 17. The lifting plate 18 and the connecting plate 19 are elastically connected by the spring rod 15. The lower end of the lifting plate 18 is fixedly installed with the piston rod 23 used in conjunction with the injector 14. When the hydraulic rod 17 drives the lifting plate 18 to move down, the alignment plate 12 passes through the ampoule and adjusts its filling position. At the same time, the alignment plate 12 contacts the bottom top rod, so that the alignment plate 12 is in the corresponding position. At this time, under the influence of the spring rod 15, the lifting plate 18 continues to move down. The lifting plate 18 squeezes the piston rod 23, so that several sets of injectors 14 can complete the quantitative delivery at the same time. With the help of the needle structure at the bottom of the injector 14, the dopamine hydrochloride solution is injected into the ampoule. After the injection is completed, the lifting plate 18 drives the injector 14 to move up. The spring rod 15 drives the lifting plate 18 and the connecting plate 19 to separate, thereby resetting the piston rod 23.
[0040] To solve the problem of multi-bottle limit calibration during its filling operation, such as Figure 3 As shown, limit rods 16 are provided at the four corners of the upper end of the lifting pressure plate 18. Several sets of elastic clamps 13 are movably installed on the inner side of the alignment plate 12. The outer surface of one end of the elastic clamp 13 is an arc-shaped groove structure. When the filling device 9 performs the filling operation, the two sets of elastic clamps 13 can respectively clamp and fix the two sides of the ampoule bottle to prevent it from tilting during filling and improve the accuracy of its docking and filling.
[0041] To solve the problem of multiple-bottle quantitative filling during its filling operation, such as Figure 2As shown, the surfaces of several sets of injectors 14 are connected by infusion pipes 20. The infusion pipes 20 are arranged vertically. The injectors 14 on both sides are equipped with inlet pipes 22 and outlet pipes 21, respectively. Solenoid valves are installed at the ends of the inlet pipes 22 and outlet pipes 21. The raw material tank 2 pumps the dopamine hydrochloride solution into the interior of several sets of injectors 14 in sequence through the inlet pipes 22 and the infusion pipes 20. The vertically arranged infusion pipes 20 can fill several sets of injectors 14 in sequence. When several sets of injectors 14 are full, the excess dopamine hydrochloride solution will flow back into the interior of the raw material tank 2 through the outlet pipes 21. When it passes through, the solenoid valve is closed to prevent it from being discharged during injection, thereby completing the injection operation of several sets of injectors 14 at the same time.
[0042] To solve the problem of continuous sealing during its filling operation, such as Figure 4 As shown, the middle of the first cutting disc 26 and the second cutting disc 28 are both driven by a rotating rod 29. One end of the rotating rod 29 is equipped with a motor 27, and the other end of the rotating rod 29 is equipped with a connecting frame 24. The connecting frame 24 has an overall T-shaped structure. The connecting frame 24 can play an auxiliary fixing role for the other end of the rotating rod 29, thereby improving the stability of the first cutting disc 26 and the second cutting disc 28 when rotating. The T-shaped connecting frame 24 facilitates the fixing of the surface of the sealing component 7.
[0043] To solve the problem of continuous sealing during its filling operation, such as Figure 5 As shown, a waste tray 4 is fixedly installed on one side of the sealing component 7, and a discharge hopper 25 is fixedly installed on the upper part of the waste tray 4. The discharge hopper 25 is inclined and located below the first cutting tray 26. A fan 6 is provided on the outer side surface of the sealing component 7. When the first cutting tray 26 and the second cutting tray 28 perform a rolling cut sealing operation on the hot melt area of the bottle mouth, the cut glass will fall onto the horizontally set first cutting tray 26, and the glass shards will be discharged into the waste tray 4 for collection through the discharge hopper 25.
[0044] A scraper 30 is installed on the upper part of the first cutting disc 26. The surface of the first cutting disc 26 is provided with a fan-shaped material outlet 31. The user drives the rotating rod 29 to rotate through the motor 27, so that the rotating rod 29 drives the first cutting disc 26 to rotate. When glass shards fall onto the first cutting disc 26, the scraper 30 can push the glass shards into the fan-shaped material outlet 31 during the rotation of the first cutting disc 26, and then let them fall down into the discharge hopper 25 through the fan-shaped material outlet 31.
[0045] To solve the problem of continuous sealing during its filling operation, such as Figure 6As shown, an arc-shaped scraper 32 is fixedly installed on the outer surface of one end of the scraper 30. The lower part of the arc-shaped scraper 32 is provided with a scraper head 33 for use with the first cutting disc 26. By setting the arc-shaped scraper 32, it can block the glass slag on the upper part of the first cutting disc 26 when it rotates, so that the glass slag can be scraped into the fan-shaped material outlet 31. Secondly, the scraper head 33 can clean the arc-shaped groove on the surface of the first cutting disc 26 when it rotates, thereby improving the rolling cutting effect of the first cutting disc 26 and the second cutting disc 28.
[0046] like Figure 7 As shown, the elastic clamp 13 and the positioning plate 12 are movably connected by an elastic rotating shaft 35. A roller 34 is movably installed at one end of the elastic clamp 13. By using the setting of the roller 34, the bottle can be pulled out from between the two sets of elastic clamps 13 when the elastic clamp 13 moves upward.
[0047] A conveyor belt 11 is provided at the upper middle part of the fixed base 1. The raw material tank 2 and the gas tank 3 are installed inside the fixed base 1 respectively. A receiving box 5 is fixedly installed at the output end of the conveyor belt 11.
[0048] Working principle: When it fills multiple ampoules at the same time, misalignment of the bottle mouths is likely to occur during the filling operation, which makes it easy for dopamine hydrochloride to spill out. At the same time, errors are likely to occur when filling multiple bottles simultaneously, which reduces the filling effect.
[0049] Therefore, by setting up the filling device 9 and the calibration plate 12, when the filling equipment for the production of dopamine hydrochloride is used, it can simultaneously complete the quantitative filling operation of multiple bottles of dopamine hydrochloride solution, avoid filling errors, and at the same time, it can simultaneously correct the filling position of multiple bottles of dopamine hydrochloride solution, prevent them from tilting, and improve its filling accuracy.
[0050] During operation, the raw material tank 2 pumps dopamine hydrochloride solution sequentially into several sets of injectors 14 through the inlet pipe 22 and the delivery pipe 20. The vertically distributed delivery pipes 20 can fill several sets of injectors 14 in sequence. When several sets of injectors 14 are full, the excess dopamine hydrochloride solution will flow back into the raw material tank 2 through the drain pipe 21, forming a circulating conveying structure between the injectors 14 and the raw material tank 2. By closing the solenoid valve, overflow of the injectors 14 during injection is prevented. The hydraulic rod 17 drives the lifting plate 18 to move down, allowing the alignment plate 12 to pass through the ampoule. Two sets of elastic clamps 13 can respectively clamp and fix the two sides of the ampoule to prevent it from tilting during filling and lift it. To ensure accurate filling, the filling position is adjusted, and the positioning plate 12 is brought into contact with the bottom top rod, so that the positioning plate 12 is in the corresponding position and the positioning plate 12 is prevented from moving further down. At this time, under the influence of the spring rod 15, the lifting pressure plate 18 continues to move down. The lifting pressure plate 18 squeezes the piston rod 23, so that several sets of injectors 14 can complete the quantitative delivery at the same time. With the help of the needle structure at the bottom of the injector 14, the dopamine hydrochloride solution is injected into the ampoule. After the injection is completed, the lifting pressure plate 18 drives the injector 14 to move up. The spring rod 15 drives the lifting pressure plate 18 and the connecting plate 19 to separate, thereby resetting the piston rod 23 for its next use. Thus, the injection operation of several sets of injectors 14 can be completed at the same time.
[0051] Secondly, the above-mentioned equipment uses a clamp structure to seal the ampoules after hot melting. The sealing operation requires stopping the conveying, which is inefficient. It does not have a continuous sealing structure and cannot complete the sealing operation simultaneously during the ampoule conveying process.
[0052] Therefore, by setting up a first cutting disc 26 and a second cutting disc 28, the filling equipment for the production of dopamine hydrochloride has a continuous rolling sealing structure when in use, replacing the traditional clamping sealing structure, thereby improving the working efficiency of its sealing operation.
[0053] In use, the hot-melted ampoules are conveyed to the sealing member 7 via conveyor belt 11. Motor 27 independently drives the first cutting disc 26 and the second cutting disc 28 to rotate. Connecting bracket 24 provides auxiliary fixation to the other end of the rotating rod 29, improving the stability of the first and second cutting discs 26 and 28 during rotation. When the end of the ampoule passes between the first and second cutting discs 26 and 28, the hot-melt portion of the ampoule is rolled and cut using the first and second cutting discs 26 and 28. The first and second cutting discs 26 and 28 are perpendicularly tangent to each other, and their rotation directions are opposite. Conversely, this allows the ampoule to pass between the first cutting disc 26 and the second cutting disc 28. The arc-shaped cuts of the first cutting disc 26 and the second cutting disc 28 make the end of the ampoule arc-shaped after rolling and cutting. The rolling and cutting between the first cutting disc 26 and the second cutting disc 28 compresses the end of the ampoule, allowing the hot-melt part to be sealed quickly. At the same time, excess glass material is removed, allowing it to fall onto the horizontally set first cutting disc 26. With the rotation of the first cutting disc 26, it is discharged. Through the first cutting disc 26 and the second cutting disc 28, the sealing operation can be quickly completed during the conveying process after the ampoule is hot-melted, improving its filling and sealing efficiency.
[0054] Meanwhile, during the filling and sealing of dopamine hydrochloride solution, some glass waste is generated after the ampoule neck is sealed. The aforementioned equipment lacks a waste removal structure, causing the waste residue to affect subsequent sealing operations and reducing its stability during use.
[0055] Therefore, by setting up a scraper 30 and a discharge hopper 25, the use of the first cutting disc 26 is optimized when the filling equipment for the production of dopamine hydrochloride is used, so that the surface of the first cutting disc 26 has an auxiliary cleaning structure, which can automatically complete the cleaning operation of glass residue.
[0056] During operation, the user drives the rotating rod 29 to rotate via the motor 27, which in turn drives the first cutting disc 26 to rotate. When glass shards fall onto the first cutting disc 26, the scraper 30 pushes the glass shards into the fan-shaped feed inlet 31 during the rotation of the first cutting disc 26. The glass shards then fall downwards into the discharge hopper 25 through the fan-shaped feed inlet 31 and are discharged into the waste tray 4 for collection through the discharge hopper 25. Furthermore, the scraper head 33 cleans the arc-shaped grooves on the surface of the first cutting disc 26 during its rotation, preventing glass shards from adhering to the arc-shaped grooves on the surface of the first cutting disc 26 and improving the rolling cutting effect of the first cutting disc 26 and the second cutting disc 28.
