Therefore, a suitable support structure can be selected according to the parts to be cleaned and installed in the operating unit 10, so that the cleaning machine 1 can be suitable for cleaning detachable parts of filling machines of different models.

[0036] Figure 3 A perspective view of the cleaning machine 1 is shown from the other side thereof, showing a medium conveying unit of the cleaning machine 1. The medium conveying unit is configured to convey the cleaning medium and / or the drying medium to the accommodation space of the heating unit 20. Figure 3 As shown, the medium conveying unit of the cleaning machine 1 includes a cleaning medium conveying unit L1 and a drying medium conveying unit L2. The cleaning medium conveying unit L1 includes a liquid inlet pipeline, a liquid supply pipeline L11, a pump 61, a liquid outlet pipeline L12 and a liquid return pipeline L14.

[0037] A liquid inlet line (not shown in the figure) is connected between the cleaning medium source and the heating unit 20, and is used to transport the cleaning medium to the accommodation space of the heating unit 20. In the embodiment shown in the figure, the cleaning medium includes water and a cleaning liquid. The cleaning machine includes a first liquid inlet P1, which is used to be connected to a water source to supply water as a first cleaning medium to the accommodation space of the heating unit 20 through a first liquid inlet line 51. In addition, a second liquid inlet P2 is provided on the wall of the heating unit 20, and the second liquid inlet P2 is used to connect to a second liquid inlet line (not shown in the figure). The second liquid inlet line is connected between the cleaning liquid source and the second liquid inlet P2 on the heating unit 20 to introduce the cleaning liquid into the accommodation space of the heating unit 20 through the second liquid inlet P2.

[0038] Figure 4FIG. 1 shows a partial pipeline of the cleaning medium delivery unit L1, wherein the second liquid inlet P2 and the second liquid inlet pipeline are not shown. Figure 3 and Figure 4 As shown, one end of the liquid supply line L11 is connected to the liquid outlet of the heating unit 20 (not shown in the figure), and the other end of the liquid supply line L11 is connected to the inlet of the pump 61. In the example shown in the figure, the liquid supply line L11 is connected to the inlet of the pump 61 via the line 52. The liquid supply line L11 is provided with a valve V1 so that the liquid supply line L11 is selectively connected to the inlet of the pump 61. The outlet of the pump 61 is connected to the liquid outlet line L12 via the outlet line 53. The pump 61 is configured to selectively pump cleaning medium (water or cleaning liquid) from the accommodating space of the heating unit 20 via the liquid supply line L11, and deliver the cleaning medium to the operating unit 10 via the liquid outlet line L12. The opening and closing of the valve V1 can be controlled accordingly by the controller in the control cabinet 40 of the cleaning machine 1 according to the cleaning operation performed.

[0039] The liquid outlet pipeline L12 is connected between the outlet pipeline 53 of the pump 61 and the operating unit 10 , so that the cleaning medium pumped by the pump 61 can be transported to the operating unit 10 through the liquid outlet pipeline L12 .

[0040] The liquid outlet pipeline L12 includes a main pipe 54 connected to the outlet pipe 53 of the pump 61 and a plurality of distribution pipes branching from the main pipe 54. In the example shown in the figure, the liquid outlet pipeline L12 includes four distribution pipes, namely, distribution pipes 55-58. Distribution pipes 55 and 56 branch from the main pipe 54 and extend into the operating unit 10 on one side, while distribution pipes 57 and 58 branch from the main pipe 54 and extend into the operating unit 10 on the other side. Each of the distribution pipes 55-58 is connected to a plurality of branch pipes spaced apart from each other. Figure 5 Distribution pipe 57 and distribution pipe 58 are shown. Figure 5As shown, the distribution pipe 57 is connected with three branch pipes spaced apart from each other, i.e., branch pipes 571, 572, 573, to deliver the cleaning medium to different positions in the operating unit 10. The liquid outlet ends of the branch pipes 571-573 are each equipped with at least one flushing nozzle. In the example shown in the figure, the liquid outlet ends of the branch pipes 571-573 are each equipped with two flushing nozzles 71, 73 spaced apart from each other in the height direction, so that the cleaning medium is sprayed to different heights in the operating unit 10, so that the components placed at different heights in the operating unit 10 can be effectively cleaned. Preferably, the flushing nozzles 71, 73 are rotatable flushing nozzles, so that the cleaning liquid can be sprayed in different directions as needed. Similarly, the distribution pipe 58 is also connected with three branch pipes spaced apart from each other, i.e., branch pipes 581, 582, 583, and each branch pipe is equipped with two flushing nozzles 72, 74 spaced apart from each other in the height direction. The distribution pipe 57 and the distribution pipe 58 are staggered in the height direction in the operating space 10. However, the present invention is not limited thereto. In other embodiments of the present invention, distribution pipe 57 and distribution pipe 58 may be arranged in other ways, as long as they do not interfere with each other. Distribution pipes 55 and 56 on the other side of operating unit 10 have a corresponding arrangement to distribution pipes 57 and 58. Through the above arrangement of distribution pipes 55-58, cleaning medium can be delivered to different locations within operating unit 10, thereby cleaning components at different locations within operating unit 10.

[0041] Preferably, each of the distribution pipes 55-58 is provided with a valve so that the cleaning medium can be supplied to a predetermined area in the operating unit 10 as needed for targeted cleaning. Figure 4 As shown, the distribution pipe 55 is provided with a valve V3, the distribution pipe 56 is provided with a valve V4, the distribution pipe 57 is provided with a valve V5, and the distribution pipe 58 is provided with a valve V6. Thus, the supply of cleaning medium to the corresponding area within the operating unit 10 can be controlled by controlling the opening and closing of the corresponding valves. The opening and closing of valves V3-V6 can be controlled accordingly by the controller in the control cabinet 40 of the cleaning machine 1 according to the cleaning operation being performed. Preferably, a manual valve V2 is also provided on the main pipe 54. The manual valve V2 can be manually controlled by the operator to connect other cleaning spray guns to manually spray cleaning medium when needed, thereby providing flexibility and targeted cleaning operations.

[0042] The inlet of the liquid return line L14 is connected to the liquid outlet pipe of the operating unit 10 through a valve (at Figure 6 ), and the outlet of the liquid return line L14 is connected to the inlet of the pump 61 via the line 52. The liquid return line L14 is configured to selectively communicate with the liquid outlet pipe of the operating unit 10, so that the cleaning medium in the operating unit 10 can be pumped out by the pump 61 and supplied to the operating unit 10 again for recycling.

[0043] The cleaning machine 1 is also provided with a liquid discharge line L13. Figure 6 FIG. 1 shows a perspective view of the cleaning machine 1 viewed from another angle, showing the arrangement of the drain line L13 and the return line L14 of the cleaning medium delivery unit L1. Figure 6 As shown, the inlet of drain line L13 is connected to the liquid outlet pipe 15 of operating unit 10 via valve V7. Preferably, a water collection tray (not shown) within operating unit 10 is installed at an angle at the bottom of operating unit 10, and liquid outlet pipe 15 is connected to a drain port (not shown) provided at the inclined bottom portion of the water collection tray, facilitating discharge of fluid within operating unit 10 through liquid outlet pipe 15. The inlet of return line L14 is connected to the liquid outlet pipe 15 of the operating unit via valve V8, and the outlet of return line L14 is connected to the inlet of pump 61 via pipe 52. Return line L14 and supply line L11 share pipe 52, which is connected to the inlet of pump 61. By controlling the opening and closing of valves V7 and V8, fluid within operating unit 10 (waste liquid or recyclable cleaning medium) can be selectively discharged into drain line L13 or return line L14. When valve V7 is open and valve V8 is closed, the drain line L13 is connected to the outlet pipe 15 of the operating unit 10, while the return line L14 is disconnected from the outlet pipe 15. Therefore, the fluid (waste liquid) within the operating unit 10 flows into the drain line L13 through the outlet pipe 15 and is discharged from the cleaning machine 1 through the drain port P3. When valve V7 is closed and valve V8 is open, the drain line L13 is disconnected from the outlet pipe 15 of the operating unit 10, while the return line L14 is connected to the outlet pipe 15. Therefore, the fluid (recyclable cleaning medium) within the operating unit 10 flows into the return line L14 through the outlet pipe 15 and is then supplied to the operating unit 10 via pump 61 for recycling. The opening and closing of valves V7 and V8 can be controlled by a controller within the control cabinet 40 of the cleaning machine 1 according to the operation being performed.

[0044] Preferably, the cleaning medium delivery unit L1 further includes a filter 63. Figure 3 and Figure 4 As shown, the filter 63 is arranged between the outlet pipe 53 of the pump 61 and the main pipe 54 of the liquid outlet pipe L12, and is used to filter impurities in the circulating cleaning medium to avoid clogging the valves and flushing nozzles arranged on the downstream pipe.

[0045] Return to see Figure 3 The drying medium conveying unit L2 of the medium conveying unit includes a fan 65 and an air flow channel ( Figure 3(not shown in the figure). The fan 65 is configured to introduce external gaseous medium as a drying medium into the heating unit 20. In the example shown in the figure, the fan 65 is configured to introduce external air as a drying medium into the heating unit 20 and into the heating elements of the heating unit 20. The fan 65 may be, for example, an axial flow fan. The heated drying medium (dry air) is introduced into the operating unit 10 through the air flow channel, drying the cleaned components within the operating unit 10 and removing water vapor from the operating unit 10.

[0046] Figure 7 Another perspective view of the washing machine 1 is shown, wherein the door 12 of the operating unit 10 and the door 21 of the heating unit 20 are not shown in order to illustrate the arrangement inside the heating unit 20. Figure 7 As shown, the heating unit 20 includes an accommodating space S defined therein. The accommodating space S is configured to receive a cleaning medium and / or a drying medium to be supplied to the operating unit 10. Preferably, the heating unit 20 further includes one or more liquid level detection elements disposed in the accommodating space S for detecting the liquid level in the accommodating space S. In the example shown in the figure, the heating unit 20 includes three liquid level detection elements 23 disposed at different heights in the accommodating space S. The liquid outlet (not shown in the figure) of the accommodating space S is connected to the liquid supply line L11, preferably as shown in FIG. Figure 3 As shown in FIG, it is selectively connected to the pipeline 52 via the liquid supply pipeline L11, and thus connected to the inlet of the pump 61.

[0047] like Figure 7 As shown, the heating unit 20 further includes a heating element 22 disposed in the accommodating space S. The heating element 22 is configured to heat the cleaning medium and / or drying medium in the accommodating space S. In one example, the heating element 22 may be an electric heating plate. The heated or unheated cleaning medium (water or cleaning liquid) in the accommodating space S can be pumped by the pump 61 through the liquid supply line L11 and pumped to the liquid outlet line L12, and then supplied to the operating unit 10. The heated drying medium (dry air) in the accommodating space S is transported to the operating unit 10 through the air flow channel formed between the accommodating space S and the operating unit 10. As Figure 7 As shown, a partition 24 is provided between the accommodating space S of the heating unit 20 and the operating unit 10. The upper portion of the partition 24 is provided with a plurality of through holes. The through holes in the partition 24 connect the accommodating space S with the operating unit 10, thereby forming an airflow channel for the drying medium delivery unit L2, which delivers the heated drying medium into the operating unit 10 for drying the cleaned components therein.

[0048] The above describes the structure and connection of each unit of the cleaning machine 1. The following describes the process of using the cleaning machine 1 to clean the detachable parts of the filling machine.

[0049] First, the parts to be cleaned are placed on the support structure 10 in the operating unit 10. Then, the corresponding button on the control cabinet 40 is operated to start and automatically perform the cleaning process. The cleaning process includes a first rinsing stage, a cleaning stage, a second rinsing stage, a third rinsing stage, and a drying stage.

[0050] During the first rinse phase, room-temperature water is supplied to the operating unit 10 for the initial rinse of the components. First, the first liquid inlet P1 is connected to a water source (e.g., a tap), allowing water, serving as the first cleaning medium, to be introduced into the accommodating space S of the heating unit 20 via the first liquid inlet line 51. When the liquid level detection element 23 detects that the water level in the accommodating space S has reached a predetermined level, the first liquid inlet line 51 stops supplying water to the heating unit 20. The valve V1 of the liquid supply line L11 opens, allowing the water flowing into the accommodating space S to flow out of the liquid supply line L11. During this phase, the heating element 22 of the heating unit 20 is inoperative, and the water in the accommodating space S is not heated. Instead, the water is pumped from the accommodating space S at room temperature through the liquid supply line L11 and line 52 by the pump 61. The water then flows out of the pump 61, passes through the outlet line 53, the filter 63, and the liquid outlet line L12, and is delivered to various locations within the operating unit 10 for the initial rinse of the components. During the first rinse phase, valve V7 of drain line L13 is open, and valve V8 of return line L14 is closed. After rinsing the components, the ambient temperature water supplied to operating unit 10 flows from outlet pipe 15 of operating unit 10 into drain line L13 and out of cleaning machine 1 through drain port P3. In one example, during the first rinse phase, the components within operating unit 10 may be rinsed twice with ambient temperature water.

[0051] Next, during the cleaning phase, heated cleaning fluid is supplied to the operating unit 10 to clean the components. The second liquid inlet P2 communicates with a second liquid inlet line (not shown) connected to a cleaning fluid source, thereby introducing the cleaning fluid, serving as the second cleaning medium, at room temperature into the accommodating space S of the heating unit 20. When the liquid level detection element 23 detects that the cleaning fluid level in the accommodating space S has reached a predetermined level, the second liquid inlet line stops supplying cleaning fluid to the heating unit 20. During the cleaning phase, the heating element 22 of the heating unit 20 operates to heat the cleaning fluid in the accommodating space S, thereby enhancing its cleaning effectiveness. After the cleaning liquid in the storage space S is heated to the desired temperature (e.g., 65°C), valve V1 on the liquid supply line L11 opens. The heated cleaning liquid is pumped by pump 61 through the liquid supply line L11 and line 52, flows out of pump 61, passes through outlet line 53, filter 63, and liquid outlet line L12, and is delivered to various locations within the operating unit 10 to clean the components within the operating unit 10. During this period, valve V7 on the liquid discharge line L13 closes, and valve V8 on the liquid return line L14 opens. After cleaning the components, the heated cleaning liquid supplied to the operating unit 10 flows from the liquid outlet pipe 15 of the operating unit 10 into the liquid return line L14, and is then supplied back to the operating unit 10 via pump 61 for recycling. In one example, during the cleaning phase, the cleaning liquid can be used to clean the components within the operating unit 10 24 times, with each cleaning cycle lasting 3 seconds.

[0052] After the cleaning is completed, the second rinsing stage begins. In the second rinsing stage, the cleaned parts are rinsed with water at room temperature to remove the cleaning liquid remaining on the parts. The second rinsing stage is similar to the first rinsing stage. The heating element of the heating unit 20 does not work, and water at room temperature is supplied to the operating unit 10 to rinse the cleaned parts. During this period, the valve V7 of the drain line L13 is opened, and the valve V8 of the return line L14 is closed. After rinsing the parts, the water at room temperature supplied to the operating unit 10 flows from the liquid outlet pipe 15 of the operating unit 10 into the drain line L13 and is discharged from the cleaning machine 1 through the drain port P3. In one example, in the second rinsing stage, the cleaned parts can be rinsed twice with water at room temperature.

[0053] Next, in the third rinse phase, heated water is supplied to the operating unit 10 for high-temperature rinsing of the cleaned components. During this phase, water is supplied to the storage space S of the heating unit 20 via the first liquid inlet line 51. The heating element 22 of the heating unit 20 then operates to heat the water within the storage space S. When the water within the storage space S is heated to the desired temperature (e.g., 70°C), the valve V1 on the liquid supply line L11 opens, and the heated water is pumped by the pump 61 through the liquid supply line L11 and line 52. The heated water then flows from the pump 61, passes through the outlet line 53, the filter 63, and the liquid outlet line L12, and is delivered to various locations within the operating unit 10 for high-temperature rinsing of the components within the operating unit 10. During this period, valve V7 of drain line L13 is open, and valve V8 of return line L14 is closed. After high-temperature rinsing of the components, the heated water supplied to operating unit 10 flows from outlet pipe 15 of operating unit 10 into drain line L13 and out of cleaning machine 1 through drain port P3. In one example, during the third rinse phase, the components within operating unit 10 can be rinsed twice with heated water.

[0054] Finally, in the drying phase, a drying medium (dry air) is supplied to the operating unit 10 to dry the cleaned components. A blower 65 draws external air into the accommodating space S of the heating unit 20, blowing it onto the heating element 22 of the heating unit 20. After being heated by the heating element 22, the air then enters the operating unit 10 through the airflow channel (through holes in the partition 24) between the accommodating space S and the operating unit 10, drying the cleaned components within the operating unit 10 and removing any water vapor. This completes the component cleaning process.

[0055] The above shows the structure of the cleaning machine 1 according to the first embodiment of the present invention and the process of using the cleaning machine 1 to clean the detachable parts of the filling machine. The cleaning machine 1 according to the present invention can automatically clean the detachable parts of the filling machine, and can heat the cleaning medium to improve the cleaning effect. After cleaning, the cleaned parts can also be dried using a drying medium without the need for workers to manually clean them. This greatly improves the cleaning efficiency, reduces labor costs, and makes it easy to control the degree of cleanliness of the cleaning. In addition, the cleaning machine 1 according to the present invention can realize the recycling of the cleaning liquid through the above-mentioned design of the medium conveying unit and the heating unit, and allows the various operating stages of the cleaning process to be carried out very coherently, and even partially simultaneously, thereby further improving the cleaning efficiency. For example, in the cleaning machine 1 according to the present invention, the prepared cleaning agent is directly supplied to the heating unit 20 and supplied to the operating unit 10 after being heated. There is no need to prepare the cleaning liquid during the cleaning process and then heat the prepared cleaning liquid and supply it to the cleaning unit. Therefore, there is no need to wait for the cleaning liquid to be prepared during the cleaning process, allowing the various stages of the entire cleaning operation to be performed more continuously. For example, while the cleaning liquid is being circulated to clean the components in the operating unit 10, the drying medium to be used can be heated in the heating unit 20.

[0056] While exemplary embodiments of the cleaning machine of the present invention have been described in detail herein, it should be understood that the present invention is not limited to the specific embodiments described and illustrated above. Those skilled in the art will be able to make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. All such modifications and variations are intended to fall within the scope of the present invention. Furthermore, all components described herein may be replaced by other technically equivalent components.
