Obviously, the embodiments described 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.

[0032] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] In the description of the present invention, it should be understood that the terms "upper" and "lower" 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 operated in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0034] The purpose of the utility model is to provide a high-viscosity filling and plugging device, which can avoid the problems of complex operation and low filling precision, so as to improve the production efficiency and quality of high-viscosity liquid filling products.

[0035] See also Figure 1 To achieve the above-mentioned purpose, the present invention provides a high-viscosity filling and plugging device, including a frame 100, a filling component and a plugging component.

[0036] The frame 100 is provided with a vacuum support 110 that can move vertically, and a filling channel 111 and a plugging channel 112 are provided on the vacuum support 110. A container 120 that can move horizontally is provided below the vacuum support 110 so that the filling channel 111 and the plugging channel 112 can be connected to the corresponding container 120.

[0037] The filling assembly includes a filling needle 210 located above the filling channel 111 and a first vacuum assembly 220 connected to the filling channel 111. The filling needle 210 is used to fill liquid into the container 120. By controlling the pressure of the filling needle 210, accurate filling of high-viscosity liquids can be achieved.

[0038] Among them, a first sleeve 113 is provided at the bottom of the filling channel 111, and the first sleeve 113 is used to connect the filling channel 111 and the container 120. When the vacuum support 110 moves downward, the first sleeve 113 is connected to the top of the corresponding container 120 to achieve a sealed connection between the container 120 and the filling channel 111.

[0039] In addition, the high-viscosity filling and plugging device also includes a liquid storage tank connected to the filling needle 210 through a second pipeline. The second pipeline is provided with a pump body for controlling the flow of liquid. The pump body can be a plunger pump, a peristaltic pump, etc. to ensure the injection volume of the liquid.

[0040] The second pipeline should use pipes with high smoothness and good inner wall cleanliness to reduce liquid residue in the pipeline, and appropriately shorten the pipeline length to reduce wind resistance and further improve transmission efficiency.

[0041] See also Figure 2The stoppering assembly includes a stoppering rod 310 located above the stoppering channel 112 and a second vacuum assembly 320 connected to the stoppering channel 112. The stoppering rod 310 is used to install the stopper above the liquid in the container 120. By controlling the pressure of the stoppering rod 310, the stable insertion of the stopper is achieved.

[0042] A second sleeve 114 is provided at the bottom of the plugging channel 112. The second sleeve 114 is used to connect the plugging channel 112 and the container 120. When the vacuum support 110 moves downward, the second sleeve 114 is connected to the top of the corresponding container 120 to achieve a sealed connection between the container 120 and the plugging channel 112.

[0043] Among them, the supply of the plug is realized through the plug supply mechanism 400, and the plug supply mechanism 400 is provided with a plug supply position corresponding to the top of the plugging channel 112. By flipping the plug supply mechanism 400, the plug is transferred from the plug supply position to the top of the plugging channel 112.

[0044] The container tray with the container 120 installed is moved to the bottom of the vacuum support 110, and the vacuum support 110 is lowered to a preset position so that the filling channel 111 and / or the stopper channel 112 are connected to the corresponding container 120. Then the filling needle 210 is lowered, and the first vacuum component 220 vacuums the container 120. The filling needle 210 fills a fixed amount of liquid into the container 120 and gradually rises. After the liquid is allowed to stand, the filling needle 210 moves up to the initial position, and the stopper rod 310 moves down to press the stopper to the upper part of the stopper channel 112. The second vacuum component 320 vacuums the container 120 filled with the liquid through the stopper channel 112. After the liquid stabilizes, the stopper rod 310 continues to move down to drive the stopper to be pressed into the liquid surface. Then the stopper rod 310 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 high-viscosity liquid filling products.

[0045] 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 210 descends to the bottom of the preparation container 120, 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 120 is vacuumed. After the vacuum is stable, the plunger pump starts filling, and the filling needle 210 rises while filling. After the filling needle 210 and the plunger pump are in place, they are sucked back. Wait for t2 until the liquid medicine is completely still, the filling needle 210 rises and leaves the filled container 120, and the filling is completed.

[0046] 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), and the stopper is provided by the stopper supply mechanism 400. With the stopper supply mechanism 400 stable, the stoppering rod 310 descends to push the stopper into the stoppering channel 112, and the stoppering rod 310 rises and returns to the initial position. After the stoppering rod 310 returns, the stopper supply mechanism 400 starts to return. After the stopper supply mechanism 400 leaves, the second sleeve 114 falls and covers the container 120, and the container 120 is vacuumed. After waiting for time t3, the vacuum control diaphragm valve is cut off, and after waiting for t4 until the liquid stabilizes, the stoppering rod 310 pushes the stopper into the pipe mouth of the container 120, and after waiting for t5 until the stopper rushes to the liquid surface, the stoppering rod 310 and the second sleeve 114 rise and leave the container 120, and the stoppering is completed.

[0047] Preferably, the container 120 is made of a polypropylene syringe. Compared with glass syringes, PP syringes are easier to control in shape and have a variety of styles. For example, if the slope at the tail transition is not smooth enough, residual tiny bubbles will often be generated. Therefore, the filling and stoppering process is also customized for such situations to ensure that corrections can be made at any time by adjusting the time, pushing speed, and vacuum frequency under different shapes.

[0048] The entire filling and stoppering process is precisely controlled by a PLC control system, ensuring accuracy and stability at every step. The system also includes a detection unit and an alarm device. The detection unit identifies the liquid and stopper in container 120, while the alarm device generates a signal to stop the filling needle 210 and stoppering rod 310. If any anomaly occurs during the filling and stoppering process, the alarm device immediately sounds an alarm and automatically stops operations, ensuring production safety.

[0049] See also Figure 3 In this embodiment, two spaced-apart plugging channels 112 are provided on the vacuum support 110, and the two plugging channels 112 are respectively connected to the second vacuum component 320. Through the one-to-one correspondence between the plugging channels 112 and the second vacuum component 320, the vacuum in the container 120 is extracted during the plugging process.

[0050] Two spaced-apart filling channels 111 are provided on the vacuum support 110. The two filling channels 111 are interconnected through a first pipe. The first vacuum component 220 is connected to the first pipe so that the two filling channels 111 are connected to the same first vacuum component 220 to realize the extraction of vacuum in the container 120 during the filling process.

[0051] The vacuum support 110 features a single-channel design for filling and a dual-channel design for plugging. Specifically, during the filling process, the two filling channels 111 share a common first vacuum assembly 220, while during the plugging process, the two plugging channels 112 each correspond to a different second vacuum assembly 320. This ensures a stable vacuum environment during both the filling and plugging processes. The absence of additional squeezing during the filling process does not affect final accuracy and does not generate additional bubbles. The dual-channel design eliminates bubbles during plugging, ensuring high stability and avoiding the risk of micro-bubbles or liquid intrusion into the plug that can occur during single-channel plugging.

[0052] The frame 100 includes a first fixing plate 130 for fixing the filling needle 210 and a second fixing plate 140 for fixing the stopper rod 310 . The first fixing plate 130 and the second fixing plate 140 are spaced apart and can both move vertically relative to the vacuum support 110 .

[0053] The vacuum support 110 is installed on the third fixed plate, and the third fixed plate is located below the first fixed plate 130 or the second fixed plate 140. During the filling process, when the third fixed plate descends to a preset position, the first fixed plate 130 and the second fixed plate 140 move along a preset trajectory to perform liquid filling and subsequent plugging.

[0054] The filling needles 210 correspond one-to-one to the filling channels 111 , and the stoppering rods 310 correspond one-to-one to the stoppering channels 112 . In this embodiment, it is preferred that two filling needles 210 perform filling and two stoppering rods 310 perform stoppering simultaneously to improve production efficiency.

[0055] In addition, considering that the filling liquid is a high-viscosity liquid, the filling needle 210 is structured using fluid polishing so that the filling needle 210 has a smooth outer wall.

[0056] In summary, the high-viscosity filling and plugging device provided by the present application includes a frame 100, a filling assembly and a plugging assembly. The frame 100 is provided with a vacuum support 110 that can move vertically, and a filling channel 111 and a plugging channel 112 are provided on the vacuum support 110. A container 120 that can move horizontally is provided below the vacuum support 110 so that the filling channel 111 and the plugging channel 112 can be connected to the corresponding container 120; the filling assembly includes a filling needle 210 located above the filling channel 111 and a first vacuum assembly 220 connected to the filling channel 111. The filling needle 210 is used to The stopper assembly includes a stopper rod 310 positioned above a stopper channel 112 and a second vacuum assembly 320 connected to the stopper channel 112. The stopper rod 310 is used to place a stopper above the liquid in the container 120. The vacuum support 110 is provided with two spaced-apart stopper channels 112, each connected to a second vacuum assembly 320. The vacuum support 110 is provided with two spaced-apart filling channels 111, interconnected by a first pipe. The first vacuum assembly 220 is connected to the first pipe. By precisely controlling parameters such as filling speed and vacuum level, and optimizing the overall process, the filling speed of high-viscosity liquids is increased, significantly improving production efficiency and reducing production costs in large-scale production environments. Designed specifically for the characteristics of PP syringes, combined with precise filling processes and parameter control, this ensures accurate filling of high-viscosity liquids, improving product quality while reducing unnecessary rework. It ensures the stability of the filling process and reduces product quality problems caused by operational errors or equipment failures.
