DETAILED DESCRIPTION

[0025] The core of the utility model is to disclose a filling and cleaning system for a strip bag machine, so as to improve the production and cleaning efficiency of the strip bag machine equipment and reduce its area occupation in the factory.

[0026] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0027] like Figure 1-3As shown, the filling and cleaning system of the strip wrap machine provided by the embodiment of the utility model includes a main body 10 and a piping system, wherein the piping system is used to provide a medicine flow path and a cleaning liquid flow path for the medicine liquid tank 110 and the filling equipment and other components in the strip wrap machine main body 10, thereby realizing the medicine filling and cleaning functions of the strip wrap machine. It should be noted that the piping system is entirely arranged on the top of the strip wrap machine and remains in position throughout the entire working cycle of the strip wrap machine. Correspondingly, when the strip wrap machine is positioned in the factory, it is only necessary to consider the position occupied by its bottom in the factory, without considering the space occupied by subsequent access equipment in the factory, thereby improving the convenience of its positioning.

[0028] As for the pipeline system specifically, the pipeline system at least includes a medicine liquid inlet pipe 20, a cleaning liquid inlet pipe 30, a compressed air pipe 40, a breathing air pipe 50, a filling pipeline 60 and a discharge pipeline 80. Each pipeline is adjusted separately to meet the filling and cleaning requirements of the strip wrapping machine. Specifically, the two ends of the medicine liquid inlet pipe 20 are respectively connected to the external medicine liquid and the medicine liquid tank 110 of the strip wrapping machine. At the same time, it is preferred that the external medicine liquid enters the medicine liquid inlet pipe 20 by pumping to make the medicine liquid flow smoother, and the medicine liquid inlet pipe 20 is connected to the chuck port on the medicine liquid tank 110 to be connected to the medicine liquid tank 110, thereby ensuring the sealing of the medicine liquid inlet pipe 20 after being connected to the medicine liquid tank 110.

[0029] The two ends of the cleaning liquid inlet pipe 30 are respectively connected to the top of the liquid medicine tank 110 and the cleaning liquid supply equipment, so that it can be opened when cleaning the pipeline system and the liquid medicine tank 110 and other components, so that the external cleaning liquid enters the liquid medicine tank 110 for cleaning, and flows through the liquid medicine tank 110 to the positions of other structural components. The purpose of the cleaning liquid inlet pipe 30 being connected to the top of the liquid medicine tank 110 is to allow the cleaning liquid to completely pass through the area of ​​the liquid medicine tank 110, thereby achieving complete cleaning of the liquid medicine tank 110.

[0030] The compressed air pipe 40 and the breathing air pipe 50 are both connected to the medicine liquid tank 110, wherein the compressed air pipe 40 is used to input compressed gas into the medicine liquid tank 110 so that the compressed gas enters the medicine liquid tank 110 and subsequent pipelines. The compressed air pipe 40 is opened when cleaning the pipeline system and components such as the medicine liquid tank 110 to pressurize the cleaning liquid so that the cleaning liquid can clean the target area more fully and thoroughly. The first end of the compressed air pipe 40 is sealed and connected to the medicine liquid tank 110, and the second end thereof can be connected to a compressed gas generating device, such as an air compressor, a vacuum generator or a gas booster pump, to provide a stable and sufficient amount of compressed gas for the cleaning system.

[0031] The breathing air pipe 50 remains open during the process of filling the medicine liquid. This is because most medicine liquid pumps use self-priming pumps, so the pressure balance in the medicine liquid tank 110 needs to be maintained during the filling process to ensure a smooth filling process. The first end of the breathing air pipe 50 is sealed and connected to the medicine liquid tank 110, and the second end is provided with a respirator to connect to the outside.

[0032] The filling pipeline 60 is used to transfer the liquid medicine in the liquid medicine tank 110 to the filling device 120. Specifically, the first end of the filling pipeline 60 is connected to the liquid medicine tank 110 to receive the liquid medicine, and the filling pipeline 60 is provided with a first branch pipe 610 and a second branch pipe 620 after being connected to the liquid medicine tank 110. The first branch pipe 610 is directly connected to the drainage pipeline 80, and the drainage pipeline 80 is connected to the waste liquid discharge position such as the floor drain. The drainage pipeline 80 is always open to ensure that the residual liquid of the entire pipeline system can be discharged smoothly. The first branch pipe 610 is used to discharge the liquid from the drainage pipeline 80. The purpose is that when the waste liquid or cleaning liquid in the medicine tank 110 is discharged, it can be directly connected to the floor drain and discharged smoothly; the conduction path of the second branch pipe 620 passes through the guide pipe of the strip packaging machine and the filling equipment 120, and is also connected to the drainage pipeline 80. The second branch pipe 620 is used to transport the medicine in the filling pipeline 60 to several filling equipment 120 after being smoothly diverted through the guide pipe, so as to output and perfuse the medicine through the filling equipment 120. At the same time, the waste liquid, residual liquid, etc. generated during the filling process can flow to the drainage pipeline 80 for discharge.

[0033] It should also be noted that each pipeline and branch pipe is provided with a valve for adjusting the opening and closing state of the corresponding pipeline to achieve independent control of the opening and closing state of a single pipeline. For example, in the case of the filling pipeline 60, valves are provided on its main pipe and two branch pipes to adjust the opening and closing of the corresponding positions.

[0034] The filling and cleaning system of the strip wrapping machine provided by the utility model integrates the pipeline system on the top of the body 10 of the strip wrapping machine, so that the pipeline system does not occupy additional space on the ground, and the medicine liquid filling and cleaning process of the strip wrapping machine is realized through a set of pipeline systems. Specifically, the pipeline system is divided into a plurality of pipelines with independent control of opening and closing, so that part of the pipelines simultaneously bear the functions of filling the medicine liquid tank 110 and cleaning the system, while the other part of the pipelines are used in different action processes. Since the pipeline part used for the cleaning system borrows the original filling pipeline 60, the setting cost of the cleaning pipeline is reduced, and a normal setting is performed, that is, when the system needs to be cleaned, it is only necessary to adjust the valve to change the opening and closing state of the corresponding pipeline, and there is no need to connect complex cleaning equipment. It is convenient and efficient when switching functions. Similarly, the process of switching to the filling production state after cleaning is completed is also easy to operate, thereby improving the production and cleaning efficiency of the strip wrapping machine equipment.

[0035] In order to enable the medicine liquid tank 110 to be cleaned more thoroughly during the cleaning process, the medicine liquid tank 110 is provided with a spray ball chuck port at the top thereof. The chuck port structure is used to firmly fix the spray ball to ensure that the spray ball will not fall off during the cleaning process, thereby ensuring the continuity and stability of cleaning. The cleaning liquid inlet pipe 30 is preferably made of corrosion-resistant material to ensure stable performance after long-term contact with the cleaning liquid. At the same time, the cleaning liquid inlet pipe 30 is directly connected to the spray ball chuck port to ensure that the cleaning liquid can flow to the spray ball without hindrance; the spray ball chuck port sprays the cleaning liquid evenly onto the inner wall of the medicine liquid tank 110 through its nozzle, thereby achieving a comprehensive and efficient cleaning effect, reducing the cleaning dead corners of the medicine liquid tank 110 during the cleaning process, and helping to improve the cleanliness of the medicine liquid tank 110.

[0036] Furthermore, in some embodiments of the present invention, the equipment for filling the drug solution is a plurality of filling needles arranged at intervals. Correspondingly, the piping system also includes a cleaning dispensing tube 70. The cleaning dispensing tube 70 is designed to divert the cleaning liquid to each filling needle so that each filling needle can be completely cleaned, while avoiding possible cross contamination and improving the safety of subsequent filling of the drug solution.

[0037] On the basis of the above-mentioned embodiment, the cleaning dispensing tube 70 is preferably raised. When the cleaning dispensing tube 70 diverts the cleaning liquid to each filling needle, the flow resistance of the diverted liquid will be large due to the small cross-sectional size of the filling needle. By raising the height of the cleaning dispensing tube 70, the horizontal height of the cleaning liquid can be increased first, and it can smoothly enter the filling needle under a certain pressure, which helps the cleaning liquid to flow in the tube and prevents the cleaning liquid from being retained, thereby further improving the sanitary conditions and cleaning effect of the system.

[0038] Taking into account that in some embodiments of the utility model, the guide tube and the filling device 120 need to operate independently, the guide tube and the filling device 120 (such as a filling needle, etc.) are independently arranged on two branch pipes. At the same time, the two branch pipes are respectively provided with opening and closing valves to allow separate opening and closing control of the pipelines where the guide tube and the filling device 120 are located. This independent setting and control design improves the flexibility of the system and the convenience of operation, so that the cleaning process can be adjusted according to actual needs, and also improves the convenience of maintenance of the guide tube and the filling device 120, which are both equipment that require regular maintenance and overhaul.

[0039] Since liquid leakage often occurs at the filling device 120, or liquid medicine drips between two infusions, in some embodiments of the utility model, a water receiving trough 130 is also designed at the bottom of the filling device 120. The receiving trough is a U-shaped trough structure, and the projection range of the water receiving trough 130 in the vertical direction covers the outlet area of ​​the filling device 120 to ensure that the liquid flowing out of the filling device 120 can be effectively collected. The bottom or one side of the open end of the water receiving trough 130 is smoothly connected to the drainage pipeline 80 to ensure that the collected liquid can be effectively discharged to avoid liquid accumulation and potential cross contamination. The setting of the water receiving trough 130 helps to keep the filling area dry and clean, and can also avoid liquid accumulation in the working environment, thereby improving working conditions.

[0040] Furthermore, in the filling and cleaning system provided in the embodiment of the utility model, the turning area of ​​each pipeline is designed to be a right angle, so that the pipeline structure can be cleaned and specific pipelines can be easily inspected and replaced, and the appearance is simpler. In addition, the valves on the straight pipelines adopt a T-type valve structure, which is convenient for fluid switching and flow direction control in the pipeline, reduces blind-end pipelines, and avoids the problem of unclean cleaning of the filling pipeline 60; the pipeline structure in the right-angle turning area enhances the stability of the pipeline and reduces the fluid dynamics loss caused by turning, and the T-type valve structure provides a more intuitive and convenient fluid control method, which improves the operational flexibility and response speed of the system.

[0041] In addition, in the filling and cleaning system provided in the embodiment of the utility model, it is preferred that the cleaning liquid supplied into the cleaning liquid inlet pipe 30 is treated purified water, and the purified water is filtered and disinfected before entering the pipeline to ensure the high purity and sterility of the cleaning liquid; supplying purified water as the cleaning liquid ensures that the inner walls of the medicine tank 110 and the filling equipment 120 will not be contaminated by impurities in the water, thereby improving the quality and safety of the final product. At the same time, the low corrosiveness of purified water also helps to extend the service life of the equipment.
