In addition, terms such as "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0036] It should be noted that, without conflict, different features in the embodiments of the present application can be combined with each other.

[0037] To solve the technical problems mentioned in the foregoing background art, the inventors have innovatively designed the following technical solutions. The specific implementation solutions of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Please refer to Figure 1 , Figure 1 which is one of the schematic diagrams of a foaming system 1 provided for this embodiment. The foaming system 1 includes a foaming platform 10 disposed in a foaming area A on a foaming production line, and a material injection assembly 20 and a foaming assembly 30 located on the foaming platform 10. The material injection assembly 20 is connected to the foaming assembly 30, and the foaming assembly 30 is used to foam the object to be foamed through the material injection assembly 20.

[0039] In this embodiment, the foaming production line generally includes a die-changing area (not shown in the figure) and a foaming area A arranged in sequence. The die-changing area is generally used to replace the mold for the object to be foamed, and then the object to be foamed after the mold replacement is moved to the foaming area A for the foaming process to achieve the heat preservation performance of the object to be foamed. The object to be foamed can be the refrigerator door body or the refrigerator box body of a refrigeration device (such as a refrigerator).

[0040] Among them, the foaming assembly 30 includes at least one foaming machine (which can include Figure 1Among the first foaming machine 300 and the second foaming machine 310), the foaming machine includes a plurality of foaming agent accommodating chambers for accommodating different types of foaming agents (the first foaming machine 300 includes a first foaming agent accommodating chamber 3001, and the second foaming machine 310 includes a second foaming agent accommodating chamber 3101). The feeding assembly 20 includes a plurality of feeding units arranged along the extending direction of the foaming platform 10 (which may include Figure 1 the first feeding unit 210 and the second feeding unit 220 in the figure). The feeding unit includes at least one feeding nozzle (the first feeding unit 210 includes a first feeding nozzle 2101, and the second feeding unit 220 includes a second feeding nozzle 2201). The feeding nozzles are respectively communicated with the corresponding foaming agent accommodating chambers through pipelines. Among them, adjacent two feeding units are arranged with a gap.

[0041] In the related art, the traditional foaming process usually has only a single foaming system. That is to say, the traditional foaming process usually adopts a foaming machine that can only carry one type of foaming agent and a single feeding nozzle connected to the foaming machine, and can only realize the foaming process of a refrigeration device (such as a refrigerator) with one energy consumption level at the same time, reducing the production efficiency. And, since the types and proportions of the foaming agents used for the heat preservation performance of refrigeration devices (such as refrigerators) with different energy consumption levels are different, therefore, the traditional foaming process cannot realize the foaming processes of refrigeration devices (such as refrigerators) with different energy consumption levels at the same time. However, the foaming assembly 30 in the foaming system 1 of this embodiment can provide different types of foaming liquids corresponding to the refrigerator door body or the refrigerator box body of refrigeration devices (such as refrigerators) with different energy consumption levels for the feeding assembly 20, and simultaneously foam the objects to be foamed with different energy consumption levels through a plurality of feeding units arranged with gaps on the foaming platform 10, so that the foaming processes of refrigeration devices (such as refrigerators) with different energy consumption levels can be realized at the same time, significantly improving the production efficiency.

[0042] Further, please refer to again Figure 1 In the extending direction of the foaming platform 10, the extending direction of the foaming platform 10 is as shown by the arrow in Figure 1 the figure. The foaming assembly 30 and the feeding assembly 20 are sequentially arranged on the foaming platform 10. Among them, the position of the feeding assembly 20 on the foaming production line is at the front end of the foaming assembly 30.

[0043] In this embodiment, on the foaming production line, the foaming platform 10 is usually in a "long strip" shape and is arranged along the extending direction of the foaming production line. The foaming assembly 30 is used to generate different foaming liquids, and the foaming liquid is a mixture of the foaming agents in multiple foaming agent accommodating chambers in the foaming machine in a certain proportion. The feeding assembly 20 is responsible for conveying different foaming liquids into the object to be foamed. The feeding assembly 20 and the foaming assembly 30 are arranged in sequence on the foaming production line. For example, the foaming assembly 30 and the feeding assembly 20 can be arranged side by side on the foaming platform 10, or the foaming assembly 30 and the feeding assembly 20 can be arranged offset on the foaming platform 10.

[0044] It should be noted that the specific setting methods of the foaming assembly 30 and the feeding assembly 20 are not specified here and need to be set according to the actual situation.

[0045] Furthermore, please refer again to Figure 1 , when the object to be foamed is the door body of a refrigeration device, the feeding assembly 20 of this embodiment further includes a first feeding bracket 200. The feeding assembly 20 further includes a first feeding unit 210 and a second feeding unit 220. The first feeding unit 210 includes a first feeding gun head 2101, and the second feeding unit 220 includes a second feeding gun head 2201. In the extending direction of the foaming platform 10, the first feeding gun head 2101 and the second feeding gun head 2201 are sequentially arranged on the first feeding bracket 200. In this way, the double-gun head design with the first feeding gun head 2101 and the second feeding gun head 2201 sequentially arranged on the foaming platform 10 can perform the foaming process on different objects to be foamed (such as the refrigerator door body) at the same time, significantly improving the production efficiency. Moreover, both the first feeding gun head 2101 and the second feeding gun head 2201 are connected to different foaming assemblies 30, and the foaming assembly 30 can provide different foaming liquids corresponding to door bodies with different energy consumption levels for the first feeding gun head 2101 and the second feeding gun head 2201. Among them, the implementation methods between the first feeding gun head 2101 and the second feeding gun head 2201 and the foaming assembly 30 can be different.

[0046] In an implementation manner of this embodiment, please refer to Figure 2 , Figure 2 This is the second schematic diagram of a foaming system 1 provided by this embodiment. The foaming assembly 30 includes a first foaming machine 300. The first foaming machine 300 is connected to the first feeding gun head 2101, and the first foaming machine 300 is also connected to the second feeding gun head 2201.

[0047] Among them, the first foaming machine 300 includes a plurality of first foaming agent accommodating chambers 3001 for accommodating different types of foaming agents. The plurality of first foaming agent accommodating chambers 3001 communicate with the first injection gun head 2101 and the second injection gun head 2201. The first foaming machine 300 foams the object to be foamed (such as the refrigerator door body) through the first injection gun head 2101 or the second injection gun head 2201.

[0048] In this embodiment, the first foaming machine 300 communicates with both the first injection gun head 2101 and the second injection gun head 2201. Different foaming agents in the plurality of first foaming agent accommodating chambers 3001 of the first foaming machine 300 can support the foaming liquid required by objects to be foamed with different energy consumption levels. In this case, the first injection gun head 2101 and the second injection gun head 2201 generally include a plurality of feeding channels and an injection gun head mixing chamber. The first foaming machine 300 includes devices such as a raw material tank and a metering pump. When the operator determines the relevant foaming parameters required for the object to be foamed (such as the refrigerator door body), the different foaming agents in the plurality of first foaming agent accommodating chambers 3001 in the first foaming machine 300 are controlled to be transported to the injection gun head mixing chamber through the metering pump in a preset certain proportion through the feeding channels, and after being mixed in the injection gun head mixing chamber, they are injected into the object to be foamed through the first injection gun head 2101 and the second injection gun head 2201. Among them, the relevant foaming parameters include parameters such as the required proportion of foaming agent and the foaming agent injection amount. Thus, the above foaming system 1 can realize the foaming process of objects to be foamed with different energy consumption levels (such as the refrigerator door body) at the same time through the first injection gun head 2101 and the second injection gun head 2201.

[0049] In another implementation manner of this embodiment, please refer to Figure 1 , the foaming assembly 30 includes a first foaming machine 300 and a second foaming machine 310. The first foaming machine 300 is connected to the first injection gun head 2101, and the second foaming machine 310 is connected to the second injection gun head 2201.

[0050] Among them, the first foaming machine 300 includes a plurality of first foaming agent accommodating chambers 3001 for accommodating different types of foaming agents. The second foaming machine 310 includes a second foaming agent accommodating chamber 3101 for accommodating one type of foaming agent. The first foaming agent accommodating chambers 3001 communicate with the first injection gun head 2101, and the second foaming agent accommodating chamber 3101 communicates with the second injection gun head 2201. The first foaming machine 300 foams the object to be foamed (such as the refrigerator door body) through the first injection gun head 2101, and the second foaming machine 310 foams the object to be foamed (such as the refrigerator door body) through the second injection gun head 2201.

[0051] In this embodiment, the types of blowing agents in the first blowing agent accommodating chamber 3001 of the first blowing machine 300 may be different from those in the second blowing agent accommodating chamber 3101 of the second blowing machine 310. The first blowing machine 300 is connected to the first injection gun head 2101, and the second blowing machine 310 is connected to the second injection gun head 2201. The blowing agents in the multiple first blowing agent accommodating chambers 3001 of the first blowing machine 300 and the blowing agent in one second blowing agent accommodating chamber 3101 of the second blowing machine 310 can support the blowing liquid required for objects to be blown (such as refrigerator door bodies) with different energy consumption levels.

[0052] It should be noted that the first blowing agent accommodating chamber 3001 of the first blowing machine 300 and the second blowing agent accommodating chamber 3101 of the second blowing machine 310 may be respectively connected to the first injection gun head 2101 and the second injection gun head 2201. The first blowing agent accommodating chamber 3001 of the first blowing machine 300 and the second blowing agent accommodating chamber 3101 of the second blowing machine 310 may also be connected to both the first injection gun head 2101 and the second injection gun head 2201. Moreover, the opening and closing between the first blowing agent accommodating chamber 3001 and the first injection gun head 2101 and the second injection gun head 2201 can be controlled by valves, and the opening and closing between the second blowing agent accommodating chamber 3101 and the first injection gun head 2101 and the second injection gun head 2201 can also be controlled by valves.

[0053] In another implementation manner of this embodiment, please refer to Figure 3 , Figure 3 FIG. 3 is a third schematic diagram of a foaming system 1 provided in this embodiment. The foaming assembly 30 includes a second blowing machine 310. The second blowing machine 310 is connected to the first injection gun head 2101 and is also connected to the second injection gun head 2201.

[0054] Among them, the second blowing machine 310 includes a second blowing agent accommodating chamber 3101 for accommodating one type of blowing agent. The second blowing agent accommodating chamber 3101 can switch different types of blowing agents. The second blowing agent accommodating chamber 3101 is connected to the second injection gun head 2201 and is also connected to the second injection gun head 2201. The second blowing machine 310 foams the object to be blown (such as a refrigerator door body) through the first injection gun head 2101 or the second injection gun head 2201.

[0055] In this embodiment, the second blowing machine 310 is connected to both the first injection gun head 2101 and the second injection gun head 2201. The number of the second blowing machines 310 may be multiple. An operator can manually switch the foaming system and realize the foaming process of objects to be blown (such as refrigerator door bodies) with different energy consumption levels at the same time through the first injection gun head 2101 or the second injection gun head 2201.

[0056] It should be noted that the above-mentioned foaming system 1 can ensure that the injection starting point of different objects to be foamed (such as the refrigerator door body) only needs to be set once, reducing the foaming switching time of the refrigerator door body in the foaming production line and further improving the production efficiency of the refrigerator door body foaming.

[0057] In addition, the first foaming machine 300 and the second foaming machine 310 can be directly arranged on the foaming platform 10, making full use of the existing foaming platform 10, reducing the floor area occupied by the first foaming machine 300 and the second foaming machine 310, and improving the space utilization rate of the foaming system 1.

[0058] In another implementation manner of this embodiment, please refer to Figure 1 , the foaming assembly 30 includes a first foaming machine 300 and a second foaming machine 310, and the first foaming machine 300 and the second foaming machine 310 are connected to the injection gun head.

[0059] Among them, the first foaming machine 300 includes a plurality of first foaming agent accommodating chambers 3001 for accommodating different types of foaming agents, the second foaming machine 310 includes a second foaming agent accommodating chamber 3101 for accommodating one type of foaming agent, the injection gun head is communicated with the first foaming agent accommodating chamber 3001, the injection gun head is also communicated with the second foaming agent accommodating chamber 3101, and the first foaming machine 300 and the second foaming machine 310 foam the object to be foamed through the injection gun head.

[0060] In this embodiment, the number of the injection gun heads can be one, the first foaming machine 300 and the second foaming machine 310 are both communicated with the injection gun head, and the different foaming agents in the plurality of first foaming agent accommodating chambers 3001 of the first foaming machine 300 and the foaming agent in the one second foaming agent accommodating chamber 3101 of the second foaming machine 310 can support the foaming liquid required by objects to be foamed (such as refrigerator door bodies) with different energy consumption levels. In this way, when the object to be foamed (such as the refrigerator door body) reaches the foaming area A, it can be flexibly switched according to the foaming liquid required by the object to be foamed, so as to realize the foaming process of the refrigerator door body of refrigeration equipment (such as refrigerators) with different energy consumption levels.

[0061] Furthermore, please refer to Figure 4 , Figure 4This is the fourth schematic diagram of a foaming system 1 provided in this embodiment. When the object to be foamed is the box body of a refrigeration device, the injection component 20 of this embodiment further includes a plurality of second injection brackets 230, the number of injection gun heads of the injection unit is multiple, and the multiple injection gun heads are respectively arranged on the plurality of second injection brackets 230. In this way, during the foaming process of the refrigerator box body, the multiple injection gun heads are respectively arranged on the second injection brackets 230, and there are gaps between the injection gun heads in different injection units, so that the foaming processes of different refrigerator box bodies can be carried out at the same time, significantly improving the production efficiency.

[0062] It should be noted that the second injection gun heads 2201 between different injection units do not interfere with each other.

[0063] Further, please refer to Figure 4 again. The injection component 20 includes a third injection unit 240 and a fourth injection unit 250. The third injection unit 240 includes a third injection gun head 2401, a fourth injection gun head 2402, a fifth injection gun head 2403 and a sixth injection gun head 2404. The third injection gun head 2401, the fourth injection gun head 2402, the fifth injection gun head 2403 and the sixth injection gun head 2404 are respectively fixed on the plurality of second injection brackets 230.

[0064] The fourth injection unit 250 includes a seventh injection gun head 2501, an eighth injection gun head 2502, a ninth injection gun head 2503 and a tenth injection gun head 2504. The seventh injection gun head 2501, the eighth injection gun head 2502, the ninth injection gun head 2503 and the tenth injection gun head 2504 are respectively fixed on the plurality of second injection brackets 230.

[0065] In this embodiment, when the object to be foamed is the box body of a refrigeration device, four injection gun heads are respectively used in the third injection unit 240 and the fourth injection unit 250 to implement the foaming process of the refrigerator box body.

[0066] Further, please refer to Figure 4 again. The foaming component 30 includes two first foaming machines 300 and a second foaming machine 310. The first foaming machine 300 and the second foaming machine 310 are connected to the injection gun heads in the third injection unit 240, and the first foaming machine 300 and the second foaming machine 310 are also connected to the injection gun heads in the fourth injection unit 250.

[0067] Among them, the first foaming machine 300 includes a first foaming agent accommodating chamber 3001 for accommodating different types of foaming agents. The second foaming machine 310 includes a plurality of second foaming agent accommodating chambers 3101 for accommodating one type of foaming agent. The first foaming agent accommodating chamber 3001 is communicated with the injection gun head in the third injection unit 240, and the first foaming agent accommodating chamber 3001 is also communicated with the injection gun head in the fourth injection unit 250. The second foaming agent accommodating chamber 3101 is communicated with the injection gun head in the third injection unit 240, and the second foaming agent accommodating chamber 3101 is also communicated with the injection gun head in the fourth injection unit 250. The first foaming machine 300 and the second foaming machine 310 foam the object to be foamed through the injection gun head in the third injection unit 240 or the injection gun head in the fourth injection unit 250.

[0068] In this embodiment, the first foaming machine 300 and the second foaming machine 310 can be respectively communicated with the third injection gun head 2401, the fourth injection gun head 2402, the fifth injection gun head 2403, and the sixth injection gun head 2404 in the third injection unit 240, and the seventh injection gun head 2501, the eighth injection gun head 2502, the ninth injection gun head 2503, and the tenth injection gun head 2504 in the fourth injection unit 250. The first foaming machine 300 and the second foaming machine 310 can also be communicated with all of the third injection gun head 2401, the fourth injection gun head 2402, the fifth injection gun head 2403, and the sixth injection gun head 2404 in the third injection unit 240, and the seventh injection gun head 2501, the eighth injection gun head 2502, the ninth injection gun head 2503, and the tenth injection gun head 2504 in the fourth injection unit 250.

[0069] In this way, it is ensured that the different types of foaming agents in the multiple first foaming agent accommodating chambers 3001 of the first foaming machine 300 and the one type of foaming agent in the second foaming agent accommodating chamber 3101 of the second foaming machine 310 can support the foaming agents required for objects to be foamed (such as refrigerator cabinets) with different energy consumption levels, and the foaming process of objects to be foamed (such as refrigerator cabinets) with different energy consumption levels can be realized at the same time.

[0070] In this embodiment, the foaming system 1 may further include a control component (not shown in the figure). The control component is connected to the foaming component 30 and the injection component 20. The operator can pre-select the injection component 20 corresponding to the object to be foamed by using the control component according to the type of the object to be foamed. At the same time, relevant foaming parameters of the foaming component 30 corresponding to the object to be foamed are set.
