[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0045] In the description of the present invention, it should be understood that the terms "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0046] The purpose of the present invention is to provide a medical viscosity liquid filling and stoppering system, which can avoid the problems of complex operation and low filling precision, so as to improve the production efficiency and quality of the viscosity liquid filling products.

[0047] See also Figure 1 To achieve the above-mentioned purpose, the present invention provides a medical viscosity liquid filling and stoppering system, including a workbench 100, a filling and stoppering component, a vacuum transmission component and a stopper supply component.

[0048] The workbench 100 is provided with a moving mechanism for horizontally moving the container 110 , and the moving mechanism can drive the container 110 to move to the bottom of the vacuum support 400 described below for subsequent filling and plugging processes.

[0049] The filling and plugging assembly is arranged on the workbench 100, and includes a filling mechanism 200 for filling liquid into the container 110 and a plugging mechanism 300 for adding a plug to the container 110. One of the filling mechanism 200 and the plugging mechanism 300 is provided with a vacuum support 400 that can move vertically, and the vacuum support 400 is provided with a filling channel and a plugging channel that can be connected to the corresponding container 110.

[0050] The vacuum transmission assembly includes a stoppering vacuum assembly 500 connected to the stoppering channel and a filling vacuum assembly 600 connected to the filling channel.

[0051] The plug supply assembly includes a plug supply mechanism 700 and a plug removal mechanism for transferring the plug to the top of the plugging channel.

[0052] See also Figure 4 and Figure 6 , wherein the plug removal mechanism includes a support frame 810, a rotating shaft 820 and a plug supply plate 830, the support frame 810 is arranged on the workbench 100; the rotating shaft 820 is arranged at the end of the support frame 810 away from the workbench 100, the rotating shaft 820 is arranged horizontally and can rotate around its own axis; one end of the plug supply plate 830 is sleeved on the rotating shaft 820 to rotate with the rotating shaft 820, and the end of the plug supply plate 830 away from the rotating shaft 820 is provided with a groove for fixing the plug.

[0053] The plug supply mechanism 700 includes a conveying position 710, a hopper 720 for storing plugs, and a conveying channel 730 for transferring the plugs from the hopper 720 to the conveying position 710. The bottom of the conveying position 710 is detachably connected to a top plug plate 740, which is used to push the plugs of the conveying position 710 tightly to the plug supply plate 830 flipped over above the conveying position 710.

[0054] The plug of the hopper 720 is transferred to the conveying position 710 through the conveying path 730, and the plug supply plate 830 can be rotated with the rotating shaft 820 to above the conveying position 710, and its trough body is correspondingly located above the plug. The top plug plate 740 set at the bottom of the conveying position 710 is lifted up to allow the plug to enter the corresponding trough body. Thereafter, the plug supply plate 830 can be rotated with the rotating shaft 820 to above the plugging channel, so that the following plugging rod 340 can press the plug into the upper end of the plugging channel for subsequent plugging of the container 110.

[0055] It should be noted that the plug supply plate 830 and the top plug plate 740 are designed to be quick-release, and no wrench is required to replace the specification parts. The plugs are fixed by vacuum adsorption to ensure accuracy during the transmission process. The number of troughs and plugging channels corresponds one to one to ensure the efficiency of single plug delivery.

[0056] The container 110 is moved horizontally to the bottom of the vacuum support 400, and the vacuum support 400 is moved downward to connect the filling channel and the plugging channel to the corresponding container 110. The filling channel is then vacuumed by the filling vacuum assembly 600 so that the filling mechanism 200 can fill the corresponding container 110 with liquid. The plug removing mechanism transfers the plug of the plug supply mechanism 700 to the top of the plugging channel and presses it into the top of the plugging channel through the plugging mechanism 300. The plugging channel is then vacuumed by the plugging vacuum assembly 500 so that the plug can be pressed into the liquid surface after the liquid level in the subsequent container 110 stabilizes. This can avoid the problems of complicated operation and low filling accuracy, thereby improving the production efficiency and quality of filling products with viscous liquids.

[0057] In this embodiment, the vacuum support 400 is provided with two spaced-apart plugging channels and two spaced-apart filling channels. The two plugging channels are respectively connected to a plugging vacuum assembly 500. The two filling channels are interconnected through a first pipe, and the filling vacuum assembly 600 is connected to the first pipe.

[0058] The vacuum support 400 features a single-channel filling and dual-channel stoppering design. During the filling process, both filling channels share a common filling vacuum assembly 600, while during the stoppering process, each channel corresponds to a different stoppering vacuum assembly 500. This ensures a stable vacuum environment during both the filling and stoppering processes. The absence of additional squeezing during the filling process does not affect final accuracy and does not introduce any additional bubbles. The dual-channel stoppering design eliminates bubbles and provides exceptional stability, eliminating the risk of microbubbles or liquid intrusion into the stopper during the single-channel stoppering process.

[0059] See also Figure 2The plugging vacuum assembly 500 and the filling vacuum assembly 600 both include a vacuum pump 510, a vacuum tank 520 connected to the vacuum pump 510, and a transmission assembly connected to the vacuum tank 520 through a first pipeline 540. The transmission assembly includes a capsule filter 531 for filtering vacuum, a diaphragm valve 532 for controlling the vacuum on and off, a reducer 533 located between the capsule filter 531 and the diaphragm valve 532, a pressure transmitter 535 connected to the diaphragm valve 532 through a second pipeline 534, and a pipe joint 536 connected to the diaphragm valve 532.

[0060] When vacuum pump 510 is activated, it transmits vacuum to vacuum tank 520, where it then passes through capsule filter 531 to filter out impurities. The vacuum is then controlled on and off by diaphragm valve 532. Vacuum pump 510 is equipped with a separate control switch, allowing for air volume adjustment without contacting the internal sterile environment. Filling and stoppering use independent air paths, preventing fluctuations in vacuum suction and facilitating independent adjustment of air volume for filling and stoppering.

[0061] See also Figure 5 The filling mechanism 200 includes a first vertical frame 210 that is arranged on the workbench 100 and can move vertically, a filling needle connected to the first vertical frame 210 through a first fixed plate 220 and located above the filling channel, a liquid storage tank connected to the filling needle through a second pipe, and a pump body 230 arranged in the second pipe to control the circulation of the liquid. The pump body 230 can adopt a plunger pump, a peristaltic pump, etc. to ensure the injection volume of the liquid. A first sleeve is provided at the bottom of the filling channel. The first sleeve is used to connect the filling channel and the container 110. When the vacuum support 400 moves downward, the first sleeve is connected to the top of the corresponding container 110 to achieve a sealed connection between the container 110 and the filling channel.

[0062] During the filling process, the plunger pump cooperates with the vacuum device to achieve accurate transmission of the liquid. When the plunger pump starts working, the vacuum device removes the air in the plunger pump to form a certain vacuum degree, thereby ensuring that the liquid can be smoothly sucked into the pump body 230.

[0063] See also Figure 3The stoppering mechanism 300 includes a second vertical frame 310 that is arranged on the workbench 100 and can move vertically, a second fixed plate 320 connected to the top of the second vertical frame 310, a third fixed plate 330 that is sleeved on the middle of the second vertical frame 310 and can move relative to the second vertical frame 310, and a stoppering rod 340 that is arranged at the bottom of the second fixed plate 320 and is located above the stoppering channel. The vacuum support 400 is detachably connected to the third fixed plate 330. A second sleeve is provided at the bottom of the stoppering channel, and the second sleeve is used to connect the stoppering channel and the container 110. The stoppering rod 340 is used to add a stopper to the top of the liquid in the container 110. By controlling the pressure of the stoppering rod 340, stable insertion of the stopper is achieved. A detector 321 for detecting the top position of the stoppering rod 340 is provided on the second fixed plate 320. When the top of the stoppering rod 340 exceeds the preset position, the detector 321 can issue an alarm for the staff to make adjustments.

[0064] The servo motor controls and coordinates the movement of the first fixing plate 220 , the second fixing plate 320 and the third fixing plate 330 relative to the workbench 100 , ensuring that each stopper and each filling needle can be accurately inserted into the target container 110 and completing the filling process.

[0065] The container is moved to the bottom of the vacuum support 400, and the vacuum support 400 is lowered to a preset position so that the filling channel and / or the stopper channel are connected to the corresponding container 110. Then the filling needle is lowered, and the filling vacuum assembly 600 vacuums the container 110. The filling needle fills a fixed amount of liquid into the container 110 and gradually rises. After the liquid is allowed to stand, the filling needle moves up to the initial position, and the stopper rod 340 moves down to press the stopper to the upper part of the stopper channel. The stopper vacuum assembly 500 vacuums the container 110 filled with liquid through the stopper channel. After the liquid stabilizes, the stopper rod 340 continues to move down to drive the stopper to be pressed into the liquid surface, and then the stopper rod 340 returns to its original position. This can avoid the problems of complicated operation and low filling accuracy, thereby improving the production efficiency and quality of filling products with viscous liquids.

[0066] The filling needles correspond to the filling channels one by one, and the stoppering rods 340 correspond to the stoppering channels one by one. In this embodiment, it is preferred that the two filling needles perform filling synchronously and the two stoppering rods 340 perform stoppering synchronously to improve production efficiency.

[0067] Filling process: At the beginning, the corresponding formula is selected and downloaded according to the filling volume and filling method (the formula includes relevant parameters of time, position, speed and vacuum degree), the rotary valve is rotated to the liquid inlet, the plunger pump rod descends and is pressed into the liquid, the filling needle descends to the bottom of the preparation container 110, and after the plunger pump rod descends into place, wait for t1, the rotary valve is rotated to the liquid outlet, and the filled container 110 is vacuumed. After the vacuum is stable, the plunger pump starts filling, and the filling needle rises while filling. After the filling needle and plunger pump are in place, they are sucked back. Wait for t2 until the liquid medicine is completely still, the filling needle rises and leaves the filled container 110, and the filling is completed.

[0068] Stoppering process: At the beginning, the corresponding formula is selected and downloaded according to the filling volume and stoppering method (the formula includes relevant parameters of time, position, speed and vacuum degree), the stopper is provided by the stopper supply mechanism 700, and the stopper supply plate 830 transfers the stopper to the top of the stoppering channel. After the stopper supply plate 830 is stable, the stoppering rod 340 descends and pushes the stopper into the stoppering channel. The stoppering rod 340 rises and returns to the initial position. After the stoppering rod 340 completes its return, the stopper supply plate 830 begins to flip away, the second sleeve falls and covers the filled container 110, and the filled container 110 is vacuumed. After waiting for time t3, the vacuum control diaphragm valve 532 is cut off, and after waiting for t4 until the liquid stabilizes, the stoppering rod 340 pushes the stopper into the pipe mouth of the container 110, and after waiting for t5 until the stopper rushes to the liquid surface, the stoppering rod 340 and the second sleeve rise and leave the container 110, and the stoppering is completed.

[0069] In addition, this embodiment also includes a pumpless filling assembly 900 arranged on the workbench 100. The pumpless filling assembly 900 is located on the side of the filling mechanism 200 away from the plugging mechanism 300, and the filling vacuum assembly 600 and the plugging vacuum assembly 500 are respectively located on both sides of the filling and plugging assembly.

[0070] In summary, the medical viscosity liquid filling and plugging system provided by this application has standardized the design of all processes related to filling and plugging, including vacuum transmission, filling, plugging and other links, which not only improves production efficiency, but also ensures the stability and precision of filling and plugging. During the filling process, a unique vacuum suction process design is adopted to ensure that each filling needle can be accurately inserted into the target container 110 and complete the precise filling process. An independent air path is used during the plugging process, making the plugging effect more stable and more precise. Through the precise displacement control and coordinated action execution of the servo motor, it is ensured that each plug and each filling needle can be accurately inserted into the target container 110 and complete the filling process, which not only improves production efficiency but also ensures product quality. The entire system adopts a modular design, which makes it easy to disassemble and replace the various components. It is not only suitable for large-scale production lines, but also for small production sites.

[0071] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
