[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0042] The core of the present invention is to provide a filling system of a strip packing machine and a strip packing machine, which can improve the filling efficiency of viscous liquids.

[0043] For a specific embodiment of the filling system of the bagging machine provided by the present invention, please refer to Figures 1 to 6 , including an import module 3, a buffer tank 1 and a filling module 2.

[0044] The inlet module 3 is used to supply materials (e.g., liquid medicine), cleaning liquids such as purified water, clean compressed gas, etc. to the buffer tank 1. It should be noted that in this embodiment, the material is a viscous liquid as an example for use, specifically liquid medicine, but the material type cannot be limited to this, for example, it can also be food or a thin liquid.

[0045] The filling module 2 is used to receive the material discharged from the buffer tank 1 and then supply it to the strip packing machine body 8. Figure 2 As shown, the filling module 2 includes a first filling pipeline 21 , a pump body 22 , a second filling pipeline 23 , a filling needle 24 , and an oscillator 25 .

[0046] The first filling pipeline 21 is connected to the outlet of the buffer tank 1. The first filling pipeline 21 is a first straight pipe arranged vertically. Since the first straight pipe has no corners, the material does not need to turn during the flow process, which can improve the smoothness of the material flow and has strong adaptability to various materials. The oscillator 25 is connected to the first filling pipeline 21.

[0047] The pump body 22 is connected to the outlet of the first filling pipeline 21. Specifically, the first filling pipeline 21 is connected to the bottom of the buffer tank 1, and the pump body 22 is located directly below the first filling pipeline 21 and the buffer tank 1. The buffer tank and the pump body 2 are directly connected up and down to ensure the material loading amount. The pump body 22 is specifically a ceramic pump with excellent acid and alkali resistance, which can resist the erosion of various strong acids and strong alkalis, and prevent the pump body 22 from rusting and cracking.

[0048] The second filling pipeline 23 is connected to the outlet of the pump body 22, and the driving force is provided by the pump body 22. The filling needle 24 is connected to the outlet of the second filling pipeline 23.

[0049] This filling system is suitable for viscous liquids. When the buffer tank 1 discharges the material, it first passes through the vertical first filling pipeline 21. The first filling pipeline 21 can ensure that the viscous liquid flows smoothly downward under the gravity and the oscillation of the oscillator 25. Then, driven by the pump body 22, it can smoothly flow through the second filling pipeline 23 to reach the filling needle 24. The filling operation is performed through the filling needle 24, which has a high filling efficiency for viscous liquids, thereby improving the production efficiency of the strip packaging machine.

[0050] like Figure 2 , Figure 5 and Figure 6 As shown, the oscillator 25 drives the first filling pipeline 21 to oscillate, thereby preventing the drug liquid from being too viscous and failing to flow from the buffer tank 1 to the inlet of the pump body 22 in time, thereby affecting the filling amount. The oscillator 25 is specifically a high-frequency oscillator.

[0051] Specifically, a plurality of first filling pipelines 21 are provided, and the outer side of each first filling pipeline 21 is respectively connected to an oscillator 25. The oscillator 25 is provided on an oscillation bracket 251, and the oscillator 25 is supported at a suitable height by the oscillation bracket 251, and can be specifically clamped, snap-fitted, or screwed.

[0052] Specifically, at least two oscillators 25 are disposed on one oscillation support 251. For example, Figure 2 As shown, the bottom of the oscillation bracket 251 is fixed to the top of the strip wrapping machine body 8, and can be specifically connected by bolts. The top of the oscillation bracket 251 is installed with an oscillator 25, and specifically two oscillators 25 can be connected.

[0053] For viscous liquid materials, due to the large flow resistance in the pipeline, the first filling pipeline 21 and the second filling pipeline 23 need to be as short as possible, as straight as possible, and as large as possible in inner diameter to ensure the flow rate. Figure 2 As shown, the second filling pipeline 23 includes a second straight tube 231 and a filling hose 232 connected between the outlet of the second straight tube 231 and the filling needle 24 , and the inlet of the second straight tube 231 is connected to the outlet of the pump body 22 .

[0054] At this time, the second straight tube 231 has no corners, and the material does not need to turn during the flow process, which can improve the smoothness of the material flow. The filling hose 232 is used as a transition between the second straight tube 231 and the filling needle 24, which can reduce the difficulty of assembling the pipeline between the second straight tube 231 and the filling needle 24.

[0055] The second straight tube 231 is placed horizontally, and the first straight tube and the second straight tube are arranged in an L shape. In addition, the first straight tube and the second straight tube 231 can also be an integrated round tube with the same diameter at all places, or a square tube, etc. Of course, in other embodiments, the second straight tube 231 can also be an arc tube, a curved tube, etc.

[0056] It should be noted that the filling hose 232 should be made of a harder material among hoses, and should be specifically adapted to the type of material to ensure that during the filling process, the material will not cause the filling hose 232 to expand, deform, or become damaged, and the filling amount will not be inaccurate.

[0057] When the liquid medicine to be filled is viscous, air may be sealed in the liquid medicine after it enters the buffer tank 1, resulting in inaccurate filling. Figure 1 As shown, on the buffer tank 1, in order to ensure the smooth flow of materials and exhaust air, a stirring device 11, a water bath heating device 13, and an electric heating device 12 are arranged, or only one or two of them may be arranged.

[0058] The stirring device 11 is a stirring motor extending into the buffer tank 1, which operates in real time to ensure that the material in the buffer tank 1 is stirred in real time. The stirring of the stirring device 11 can remove the gas in the liquid medicine and increase the fluidity of the liquid medicine.

[0059] The water bath heating device 13 may include a water layer arranged on the outer layer of the buffer tank 1, such as Figure 1 As shown, the water-passing layer can wrap the side and bottom of the buffer tank 1, and has a hot water inlet 131 connected to the top of the water-passing layer and a hot water outlet 132 connected to the bottom of the water-passing layer. Hot water enters the water-passing layer through the hot water inlet 131 and is then discharged from the hot water outlet 132. The hot water can be directly used as existing hot water, such as hot water in other processes in the production process.

[0060] Among them, the electric heating device 12 can be set at the bottom of the buffer tank 1 and started as needed, for example, timed start, or control the start time and temperature according to the flow rate of the material in the filling module 2, or start when there is no hot water but there is a heating demand.

[0061] By adding the heating function through the water bath heating device 13 and the electric heating device 12, the viscosity of the viscous liquid medicine can be reduced due to the increase in temperature, thereby increasing the fluidity of the liquid medicine.

[0062] In addition, a pressurizing port is provided on the buffer tank 1 for pressurizing the buffer tank 1. The buffer tank 1 is connected to compressed gas to increase the filling pressure of the liquid medicine, and specifically, an external air pump can be connected.

[0063] Specifically, during the pressurization control, the pressurization process can be controlled in combination with the detection value of the liquid level sensor 17 of the buffer tank 1. The liquid level sensor 17 can use laser detection. When the liquid level sensor 17 in the buffer tank 1 detects that the liquid level of the material therein rises to the set liquid level, the buffer tank 1 is pressurized until the liquid level drops to a certain distance below the set liquid level, ensuring that the material moves downward, and avoiding excessive resistance caused by excessive amount of stored material and excessive viscosity, ensuring that pressure is provided to the material in a timely manner to assist the movement of the material.

[0064] In addition, the buffer tank 1 has a plurality of discharge ports 14, for example, 6. Each discharge port 14 of the buffer tank 1 is connected to a different filling module 2. By selecting a buffer tank 1 with a plurality of discharge ports 14, the buffer tank 1 can be used to directly supply materials to a plurality of second filling pipelines 23, such as Figure 6 As shown, six discharge ports 14 are arranged at the bottom of the buffer tank 1 , and the six filling modules 2 are connected to the discharge ports 14 one by one.

[0065] Among them, each filling module 2 can be set to be the same, which can ensure that the amount of medicine in each filling module 2 is basically consistent. At this time, the material discharged from the buffer tank 1 directly reaches the inlet of the pump body 22 through the first filling pipeline 21, and then is discharged to the second filling pipeline 23 and the filling needle 24.

[0066] The buffer tank 1 may be a trough-type buffer tank with a plurality of discharge ports 14. In other embodiments, a circular buffer tank may also be used.

[0067] At this time, compared with the buffer tank 1 with one discharge port 14, it is beneficial to shorten the liquid stroke of the filling module 2: for the buffer tank 1 with one discharge port 14, when discharging, a main discharge pipe is required to be connected to the buffer tank 1, and then a plurality of branch pipes are respectively connected to the outlet of the main discharge pipe for liquid separation to supply different filling modules 2. Compared with the buffer tank 1 in this embodiment that is directly connected and supplies multiple filling modules 2, when the straight-line distance between the discharge port 14 and the filling needle 24 is the same, the former method requires liquid separation, and the liquid stroke is longer, while the latter method adopted in this embodiment can set the liquid stroke more flexibly and can be set to a smaller stroke, which is more suitable for the filling of viscous liquids with large flow resistance and slow flow rate, and can reduce the loss of filling volume and filling resistance caused by material adhesion to the pipeline.

[0068] Among them, the filling system also includes an import module 3, such as Figure 1 and Figure 4As shown, the inlet module 3 includes a first valve V1, a second valve V2, a feed pipe 31 and a cleaning pipe 32. The first valve V1 and the second valve V2 can be pneumatic valves. The inlet module 3 can be connected to the chuck port of the buffer tank cover. The inlet module 3 is located above the buffer tank 1 to clean the strip bag machine from a high place.

[0069] The first valve V1 is a T-type valve, including a side inlet 91, a side outlet 92 and a bottom outlet 93, and can control the side inlet 91 to be connected to the side outlet 92 or to be connected to the bottom outlet 93. Optionally, in this T-type valve, the side inlet 91 and the bottom outlet 93 can be kept in a connected state, and the opening and closing of the side inlet 91 and the side outlet 92 can be controlled by opening and closing the T-type valve. The use of a T-type valve can reduce the number of blind-end filling pipelines and prevent the filling pipeline from being uncleanly cleaned.

[0070] The cleaning pipe 32 is connected between the lateral outlet 92 and the cleaning port 15 of the buffer tank 1. The cleaning liquid can enter the buffer tank 1 through the lateral inlet 91 of the first valve V1, the lateral outlet 92, and the cleaning pipe 32 to clean the buffer tank 1. Specifically, the cleaning pipe 32 is used for the cleaning liquid to enter the filling and cleaning related pipelines, and is connected to the corresponding chuck port of the buffer tank cover, and is used to clean the liquid tank and the liquid filling pipeline. The cleaning liquid is mostly purified water.

[0071] The feed pipe 31 is connected between the bottom outlet 93 and the feed port of the buffer tank 1, and the second valve V2 is provided on the feed pipe 31 to control the on-off of the feed pipe 31. The material can enter the buffer tank 1 through the side inlet 91 of the first valve V1, the bottom outlet 93, and the feed pipe 31 to realize the feeding of the buffer tank 1, and the second valve V2 can control the on-off of the material on the feed pipe 31 to improve the accuracy of the control of the feeding amount.

[0072] The feed pipe 31 is a third straight pipe arranged vertically to ensure smooth downward flow of the material.

[0073] In addition, if Figure 1 As shown, the inlet module 3 further includes a spray ball 33 , which is disposed at the cleaning port to improve the cleaning effect on the buffer tank 1 .

[0074] The inlet module 3 can be used for cleaning after the production is completed, and purified water and compressed gas can be passed through. Purified water is used to clean part of the liquid inlet pipe, and compressed gas is used to purge and clean the inlet module 3. In addition, the cleaning pipe 32 can also be used as a pressurization port for compressed gas, which is used to pressurize the buffer tank 1 during filling production. If the drug liquid is too viscous and affects the filling production, the flow rate of the drug liquid can be increased by pressurizing the buffer tank 1 to meet the production requirements.

[0075] Of course, in addition to using the above-mentioned cleaning structure in the filling system, manual cleaning can also be combined to ensure the cleaning quality.

[0076] During the cleaning process, in order to achieve sewage discharge, such as Figure 1 , Figure 2 and Figure 4 As shown, the sewage outlet 16 of the buffer tank 1 is connected to the first sewage pipe 4, the first sewage pipe 4 is provided with a third valve V3, a water receiving tank 5 is provided below the filling needle 24, the outlet of the water receiving tank 5 and the outlet of the first sewage pipe 4 are both connected to the second sewage pipe 6, and the second sewage pipe 6 is provided with a fourth valve V4. In addition, a conductivity detection meter 61 can also be provided on the second sewage pipe 66. After cleaning, the cleaning liquid in the second sewage pipe 6 can be discharged to the floor drain. The third valve V3 and the fourth valve V4 can specifically be pneumatic valves.

[0077] The filling system in this embodiment refers to Figure 4 Flow path, working principle includes:

[0078] 1. Filling process: feeding liquid medicine - closing the first valve V1 - opening the second valve V2 - feeding pipe 31 - buffer tank 1 - first filling pipeline 21 - pump body 22 - second filling pipeline 23 - filling needle 24 - packaging bag.

[0079] 2. Cleaning process:

[0081] 2. Buffer tank 1 cleaning: purified water - first valve V1 (open) - second valve V2 (closed) - cleaning ball - buffer tank 1 - third valve V3 (open) - fourth valve V4 (open) - floor drain. The purpose of this step is to use purified water as the medium to rotate and flush the buffer tank 1 through the spray ball 33 of the buffer tank 1, and then discharge the sewage from the buffer tank 1.

[0082] 3. Cleaning of filling needle 24: After production is completed and buffer tank 1 is cleaned, this process is executed, namely: purified water - first valve V1 (closed) - second valve V2 (open) - buffer tank 1 - pump body 22 - filling needle 24 - water tank 5 - fourth valve V4 (open) - floor drain. At this time, the cleaning medium is purified water, which cleans the filling needle 24, guide tube and other structures at the terminal. At the same time, the cleaning liquid is collected in the water tank 5 - fourth valve V4 (open) - discharged to the floor drain.

[0083] The filling system in this embodiment can provide the strip wrapping machine with filling and cleaning functions for materials such as viscous liquid medicines. It has stable filling, high cleaning cleanliness, simple structure, high integration, and small space occupation.

[0084] In addition to the above-mentioned filling system, the present invention further provides a strip wrapping machine, which includes a strip wrapping machine body 8 and a filling system. The filling system can specifically be the filling system provided in any of the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly.

[0085] At this time, in the strip wrapping machine, the buffer tank 1 is located at the highest point of the strip wrapping machine, and gravity can be used to increase the filling assistance of viscous liquid medicines, increase the flow rate, and improve the filling efficiency. In addition, the buffer tank 1 and the pump body 22 and other equipment are placed above the strip wrapping machine body 8, which can effectively reduce the equipment footprint and is suitable for pharmaceutical factories with insufficient factory area but relatively high factory height.

[0086] In addition, the buffer tank 1 and / or the pump body 22 can be arranged on the filling support frame 7, and the filling support frame 7 is arranged above the filling support frame 7 to meet the height requirements of the buffer tank 1 and / or the pump body 22. In addition, the buffer tank 1 and / or the pump body 22 can also be arranged above the filling lifting assembly 26, specifically, the filling lifting assembly 26 fills the support frame 7 to meet the height requirements of the equipment.
