Description

Technical Field

[0001] This invention belongs to the field of gynecological gel tube filling technology, specifically a filling mechanism for a gynecological gel tube filling machine. Background Technology

[0002] Gynecological gels are a type of gel-based medication specifically designed for gynecological inflammation. They are mild in texture and easily absorbed locally, primarily used to treat common gynecological conditions such as bacterial vaginosis, yeast infections, and chronic cervicitis. They effectively inhibit the growth of pathogenic microorganisms and relieve discomfort such as itching, odor, and abnormal discharge. Filling is a crucial step in the production process. A specialized filling device is used to precisely fill the finished gel in measured quantities. This device not only accurately controls the dosage and ensures the packaging is airtight but also prevents the gel from coming into contact with external contaminants during filling, thus guaranteeing the safety and clinical efficacy of the medication.

[0003] Existing gynecological gel tube filling machines have significant deficiencies in terms of cleaning and preventing cross-contamination: the connection point of the filling nozzle that contacts the gel is difficult for operators to clean from the outside due to the gaps in the sealing ring and the structural design. Regular cleaning methods are inaccessible, so manual disassembly and cleaning are usually required. However, the disassembly process is time-consuming, resulting in low cleaning efficiency. Furthermore, improper operation can easily lead to incomplete cleaning, and residual gel can cause cross-contamination between batches, making it difficult to meet the aseptic standards for gynecological gel production and posing risks to product quality and safety. In order to address the above problems, this invention proposes a filling mechanism for a gynecological gel tube filling machine. Summary of the Invention

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention enables the stirring shaft, stirring paddle, two sets of stirring blades, and scrapers to rotate synchronously inside the storage tank by starting the drive motor. When the two sets of stirring blades rotate, they can stir the gel in the middle of the storage tank, and when the stirring paddle rotates, it can stir the gel at the bottom of the storage tank. This design can maintain the stability of the gel viscosity and prevent particle sedimentation. When the two sets of scrapers rotate, they can clean the inner surface of the storage tank, and can scrape off the gel attached to the tank wall in real time, avoiding the situation where residual gel stays on the tank wall for a long time and deteriorates. Furthermore, no additional treatment of stubborn residues on the tank wall is required during subsequent cleaning, which can reduce the risk of cross-contamination between batches.

[0020] 2. This invention allows the valve body to connect to an external cleaning solution. Rotating the valve stem causes the valve ball to rotate inside the valve body. When the flow hole is perpendicular to the inside of the upper and lower ends of the valve body, the cleaning solution enters the interior of the tapered inner hole through the flushing pipe. The tapered inner hole creates a vortex that flows towards the discharge pipe. This design allows operators to clean the interior of the tapered inner hole and the discharge pipe without disassembling the filling pipe, significantly reducing cleaning time and the risk of cross-contamination.

[0021] 3. This invention can use a cylinder to push the limiting plate to fix the position of the gel tube to be filled, thereby improving the stability of the filling process and preventing the gel tube from shifting between the position and the discharge pipe during filling. Pulling the pull plate can cause the fixing pin to disengage from the inside of the fixing groove. At this time, pulling the limiting plate can cause the mounting block to disengage from the inside of the mounting base. This design allows the operator to replace the limiting plate in a relatively time-saving and labor-saving manner when it is worn. Attached Figure Description

[0031] 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.

[0032] like Figures 1 to 8 As shown, this embodiment of the invention provides a filling mechanism for a gynecological gel tube filling machine, including a support structure 1. The support structure 1 includes a support base 11, a transmission mechanism 12 installed inside the upper surface of the support base 11, a feeding baffle 13 fixedly connected to one end of the upper surface of the support base 11, and a feeding port 14 fixedly connected to the outer surface of one end of the support base 11.

[0033] The storage structure 2 includes a support frame 21, a storage tank 22, a drive motor 24, a stirring blade 26, a scraper 27, a stirring paddle 28, a second conveying pump 29, a conveying pipe 210, an electric push rod 213, and a connecting frame 214. The stirring blade 26, the scraper 27, the electric push rod 213, and the connecting frame 214 are each provided in two sets. The lower surface of the support frame 21 is fixedly connected to the other end of the upper surface of the support base 11.

[0034] The filling structure 3 includes a connecting seat 31, a first connecting port 32, a second connecting port 33, a filling pipe 34, a flushing pipe 36, a tapered inner hole 37, a discharge pipe 38, a valve body 39, and a valve ball 310. The outer surfaces on both sides of the connecting seat 31 are fixedly connected to the opposite ends of the two sets of electric push rods 213. The second connecting port 33 is connected to the interior of one end of the second delivery pump 29. A one-way valve is installed at the lower end of the tapered inner hole 37.

[0035] The limiting structure 4 includes a cylinder 41, a mounting base 42, a mounting block 43, a fixing groove 44, a limiting plate 45, a fixing base 46, and a fixing pin 47. The cylinder 41 is installed on the other end of the upper surface of the support base 11.

[0036] The support base 11 is equipped with a servo motor, and the output shaft of the servo motor is fixedly connected to the center of the lower surface of the transmission mechanism 12. Starting the servo motor can drive the transmission mechanism 12 to rotate and transport the gel tube. After filling, the external capping mechanism can seal the filled gel tube. When the gel tube moves to the discharge port 14, the discharge baffle 13 will push the gel tube to fall into the discharge port 14.

[0037] like Figures 2 to 3As shown, the storage tank 22 is fixedly connected to the upper end of the support frame 21. A first delivery pump 23 is installed on the outer surface of one side of the storage tank 22, and the outlet of the first delivery pump 23 is connected to the interior of the storage tank 22. The drive motor 24 is installed on the upper surface of the storage tank 22, and a stirring shaft 25 is fixedly connected to the output shaft of the drive motor 24. The bearing of the stirring shaft 25 is connected to the interior of the upper surface of the storage tank 22.

[0038] The external gel is extracted by the first delivery pump 23 and delivered to the storage tank 22. The drive motor 24 is started to drive the stirring shaft 25 to rotate inside the storage tank 22. The connection between the stirring shaft 25 and the upper surface of the storage tank 22 is equipped with a static double-end mechanical seal, which can improve the sealing of the storage tank 22 and improve the stability of the stirring shaft 25 during rotation. The drive motor 24 has a power of 0.5-1.5kW and a speed of 100-300r / min, which is dynamically adjusted according to the viscosity of the gel. For every 1000cP increase in viscosity, the speed increases by 50r / min.

[0039] like Figures 2 to 3 As shown, two sets of stirring blades 26 are fixedly connected to the outer surfaces of both sides of the stirring shaft 25, and two sets of scrapers 27 are fixedly connected to one end of the two sets of stirring blades 26 near the inner surface of the storage tank 22. The outer surfaces of the two sets of scrapers 27 are attached to the inner surface of the storage tank 22, and a stirring paddle 28 is fixedly connected to the outer surface of the lower end of the stirring shaft 25.

[0040] When the stirring shaft 25 rotates, it can drive the stirring paddle 28, the two sets of stirring blades 26 and the scraper 27 to rotate synchronously. The two sets of stirring blades 26 can form axial and radial compound stirring in the middle of the storage tank. In view of the high viscosity characteristics of gynecological gel, it can break the cohesion inside the gel and prevent viscosity stratification caused by static or local temperature differences. When the stirring paddle 28 rotates, it can prevent the gel deposited at the bottom of the storage tank 22 from hardening and prevent particles from settling. When the two sets of scrapers 27 rotate, they can clean the inner surface of the storage tank 22, and can scrape off the gel attached to the tank wall in real time, avoiding the situation where residual gel stays on the tank wall for a long time and deteriorates. Furthermore, no additional treatment of stubborn residues on the tank wall is required during subsequent cleaning.

[0041] like Figures 2 to 3 As shown, the second delivery pump 29 is installed on the lower surface of the storage tank 22. The inlet of the second delivery pump 29 is connected to the interior of the lower surface of the storage tank 22, and the delivery pipe 210 is connected to the outlet of the second delivery pump 29.

[0042] The second delivery pump 29 can extract the gel inside the storage tank 22 and deliver it through the delivery pipe 210 to the inside of the tapered inner hole 37 and the discharge pipe 38.

[0043] like Figures 2 to 3As shown, connecting rods 211 are fixedly connected to both sides of the front surface of the support frame 21, and fixing plates 212 are fixedly connected to the upper ends of the two sets of connecting rods 211. Two sets of electric push rods 213 are respectively installed on the lower surfaces of the two sets of fixing plates 212. One end of the push rod inside the two sets of electric push rods 213 is fixedly connected to the upper surface of the two sets of connecting frames 214, and the ends of the two sets of connecting frames 214 away from the connecting seat 31 are slidably connected to the outer surfaces of the two sets of connecting rods 211.

[0044] The activation of the two sets of electric push rods 213 can drive the two sets of connecting frames 214 to move longitudinally in sync, and drive the filling structure 3 to move synchronously as a whole. The two sets of electric push rods 213 are linked by a synchronous controller model SYN-2D. The sliding connection between the two sets of connecting rods 211 and the two sets of connecting frames 214 can effectively improve the stability of the filling structure 3 when it moves as a whole, and can prevent it from shaking during movement.

[0045] like Figures 4 to 6 As shown, the first connecting port 32 and the second connecting port 33 are respectively opened inside the connecting seat 31. The upper surface of the filling tube 34 is fixedly connected to the lower surface of the first connecting port 32. The filling tube 34 has a tapered inner hole 37 inside, and the inner diameter of the upper inlet gradually changes from 8mm to 3mm at the lower outlet. A connecting hole 35 is opened inside one side of the upper surface of the filling tube 34, and the connecting hole 35 is connected to the interior of the second connecting port 33 and the tapered inner hole 37. The flushing tube 36 is fixedly connected to the interior of the other side of the upper surface of the filling tube 34. The flushing tube 36 is connected to the interior of the first connecting port 32 and the tapered inner hole 37. The lower surface of the filling tube 34 is fixedly connected to the discharge tube 38, and the interior of the discharge tube 38 is connected to the interior of the tapered inner hole 37.

[0046] The gel inside the delivery pipe 210 can be transported to the interior of the tapered inner hole 37 through the second connecting port 33. The tapered inner hole 37 adopts a linear gradient slope of 0.05mm / mm, and the inner wall is polished with a roughness Ra≤0.8μm to avoid gel retention. The tapered inner hole 37 forms a smooth gradient structure with a coarse inlet and a fine outlet, so that after the gel enters from the wide-diameter inlet, it forms an accelerated flow guiding effect along the inner wall of the tapered inner hole 37: the flow velocity smoothly increases from 0.5m / s at the inlet end to 1.2m / s at the outlet end, further avoiding local turbulence and retention. At the same time, the gradient structure can reduce the contact area between the gel and the hole wall, which can reduce the probability of gel adhesion to the hole wall.

[0047] like Figures 4 to 5As shown, the lower end of the valve body 39 is fixedly connected to the upper surface of the connecting seat 31. The interior of the valve body 39 is connected to the first communication port 32. The valve ball 310 is rotatably connected to the interior of the valve body 39. The interior of the valve ball 310 is provided with a flow hole 311, and the flow hole 311 is connected to the interior of the valve body 39. A valve stem 312 is fixedly connected to the outer surface of one side of the valve ball 310, and the valve stem 312 is hinged to the interior of one side surface of the valve body 39.

[0048] The valve body 39 has a sealing gasket inside, which is attached to the outer surface of the valve ball 310. This improves the sealing performance of the valve ball 310 when it is in a sealed state. Rotating the valve stem 312 can drive the valve ball 310 to rotate inside the valve body 39. When the flow hole 311 is perpendicular to the inside of the upper and lower ends of the valve body 39, the cleaning solution enters the interior of the tapered inner hole 37 through the flushing pipe 36. The tapered inner hole 37 forms a spiral downward flushing trajectory along the hole wall of the tapered inner hole 37, covering the entire hole wall area from the inlet end to the outlet end of the tapered inner hole 37. The centrifugal force of the spiral flow can peel off and carry away the gel residue attached to the hole wall of the tapered inner hole 37, which can effectively reduce the amount of gel residue on the hole wall.

[0049] like Figure 7 As shown, the rear surface of the mounting base 42 is fixedly connected to one end of the push rod inside the cylinder 41, the mounting block 43 is slidably inserted into the interior of the front surface of the mounting base 42, the fixing groove 44 is opened in the interior of the upper surface of the mounting block 43, and the rear end of the limiting plate 45 is fixedly connected to the front end of the mounting block 43.

[0050] The starting cylinder 41 can push the limiting plate 45 to fix the position of the gel tube to be filled, thereby improving the stability of the filling process. The surface of the front end of the limiting plate 45 is provided with a flexible silicone layer with a hardness of 50-60 Shore A. Since the silicone has good elasticity and a high coefficient of friction, it can prevent the tube from sliding. It can also absorb the pressure and disperse the pressure through the elastic deformation of the silicone, preventing excessive local pressure, thereby avoiding damage to the gel tube during the limiting process.

[0051] like Figures 7 to 8 As shown, the fixing base 46 is fixedly connected to the upper surface of the mounting base 42, the fixing pin 47 is slidably inserted into the interior of the lower surface of the fixing base 46, the outer surface of the fixing pin 47 is attached to the inner surface of the fixing base 46, the pull plate 48 is slidably inserted into the interior of the front surface of the fixing base 46, and the rear end of the pull plate 48 is fixedly connected to the upper end of the front surface of the fixing pin 47, the lower end of the fixing pin 47 is slidably inserted into the interior of the upper surface of the mounting base 42, and the lower end of the fixing pin 47 is inserted into the interior of the fixing groove 44.

[0052] When the lower end of the fixing pin 47 is provided with the interior of the fixing groove 44, the position of the mounting block 43 can be fixed to prevent it from moving inside the mounting base 42 or detaching from the mounting base 42. Pulling the pull plate 48 can cause the lower end of the fixing pin 47 to detach from the interior of the fixing groove 44. At this time, pulling the limiting plate 45 can cause the mounting block 43 to detach from the interior of the mounting base 42, making it easier for the operator to disassemble and install the limiting plate 45. The lower surface of the pull plate 48 is provided with anti-slip texture, which can increase the friction between the pull plate 48 and the operator's hand and prevent the operator from slipping when pulling the pull plate 48.

[0053] like Figure 8 As shown, the upper surface of the fixing pin 47 elastically abuts against the compression spring 49, and the upper end of the compression spring 49 elastically abuts against the upper surface inside the fixing seat 46.

[0054] The compression spring 49 can exert a continuous downward force on the fixing pin 47, thus effectively improving the stability of the fixing pin 47 when it is inserted into the fixing groove 44.

[0055] Working principle and usage process: First, the first conveying pump 23 in the storage structure 2 draws external gel and delivers it to the storage tank 22. The drive motor 24 is started to drive the stirring shaft 25, stirring paddle 28, two sets of stirring blades 26, and scraper 27 to rotate synchronously. The stirring blades 26 stir the gel in the middle of the storage tank 22, the stirring paddle 28 stirs the gel at the bottom of the storage tank 22 to prevent particle sedimentation, and the scraper 27 scrapes off the gel residue attached to the inner wall of the storage tank 22. Then, the two sets of electric push rods 213 in the storage structure 2 are started to push the connecting frame 214 to move the filling structure 3 as a whole to adjust the filling position. At the same time, the servo motor of the support seat 11 in the support structure 1 is started, driving the transmission mechanism 12 to rotate and deliver the gel tube to be filled to the corresponding filling position. Then, the cylinder 41 in the limiting structure 4 is started to push the mounting seat 42, mounting block 43 and limiting plate 45 to move. The flexible silicone layer at the front end of the limiting plate 45 limits the gel tube to be filled. The position is fixed to prevent displacement during filling. Then, the second conveying pump 29 in the storage structure 2 is started to draw the gel from the storage tank 22. The gel enters the tapered inner hole 37 through the conveying pipe 210, the second connecting port 33 and the connecting hole 35 in the filling structure 3, and is guided to the discharge pipe 38 along the tapered inner hole 37. The discharge pipe 38 completes the filling of the gel tube. After filling, the conveying mechanism 12 continues to convey the gel tube to the subsequent process. When cleaning is required, the valve body 39 is connected to the external cleaning solution. The valve stem 312 is rotated to drive the valve ball 310 so that the flow hole 311 is perpendicular to the upper and lower ends of the valve body 39. The cleaning solution enters the tapered inner hole 37 through the flushing pipe 36 and forms a vortex to flow towards the discharge pipe 38, thereby cleaning the tapered inner hole 37 and the inside of the discharge pipe 38. If the limiting plate 45 is worn, the pulling plate 48 is pulled to drive the fixing pin 47 to disengage from the fixing groove 44. The limiting plate 45 can then be pulled to disengage the mounting block 43 from the mounting seat 42 for replacement.

[0056] However, as is well known to those skilled in the art, the working principles and wiring methods of the discharge baffle 13, the first conveying pump 23, the drive motor 24, the second conveying pump 29, the electric push rod 213, and the cylinder 41 are commonplace and belong to conventional methods or common knowledge. Therefore, they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
