Description

Technical Field

[0001] This invention relates to the field of surface treatment technology, and in particular to a surface treatment device for thin-walled shells used in the manufacture of photovoltaic prefabricated cabins. Background Technology

[0002] A prefabricated photovoltaic (PV) module is a modular box structure that integrates the core equipment of a PV power generation system. It highly integrates PV combiner, inverter, and monitoring devices within the prefabricated module, employing a factory prefabrication and on-site hoisting method, which significantly shortens the construction cycle.

[0003] In the manufacturing process of photovoltaic prefabricated cabins, surface grinding equipment is often used to treat the surface of thin-walled shells. Currently, common surface grinding equipment generates a lot of heat by rubbing against the surface of the thin-walled shell during grinding. Cooling is usually achieved by spraying cooling water, but this requires a pump, which is costly and wasteful of water resources. Furthermore, the thin-walled shell has no internal support during processing, making it more prone to deformation and affecting the quality of the finished product. Before grinding, a fixing structure is usually required to fix the thin-walled shell, and then the surface grinding equipment is controlled to grind it. After grinding, the fixing structure must be removed before the next round of operation can begin. The surface of the thin-walled shell is still hot after grinding, making it difficult to remove quickly and hindering continuous surface treatment of the thin-walled shell. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of common surface grinding equipment, which generates a large amount of heat during grinding due to friction with the surface of thin-walled shells. Cooling is usually achieved by spraying cooling water, but this requires a pump, which is costly and wasteful of water resources. Furthermore, the thin-walled shells lack internal support during processing, making them more prone to deformation and affecting the quality of the finished product. Moreover, it is difficult to achieve continuous processing of the surface of thin-walled shells. Therefore, this invention proposes a surface treatment device for thin-walled shells used in the manufacture of photovoltaic prefabricated cabins.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A thin-walled shell surface treatment device for manufacturing photovoltaic prefabricated cabins includes a thin-walled shell surface treatment mechanism, wherein the thin-walled shell surface treatment mechanism is provided with multiple grinding auxiliary mechanisms;

[0007] The thin-walled shell surface treatment mechanism includes a bottom shell and a grinding assembly. A feeding assembly is provided in the bottom shell. An arc-shaped strip is fixedly connected to the side wall of the bottom shell. An annular plate is fixedly connected to the bottom wall of the bottom shell. Two continuous raised parts are provided on the annular plate.

[0008] The grinding auxiliary mechanism includes a support assembly for placing the thin-walled shell. An active hydraulic assembly is provided on the support assembly and is connected to a liquid storage shell. The liquid storage shell is placed on the support assembly, and an autonomous expansion and positioning assembly is connected above the liquid storage shell. The active hydraulic assembly moves to the arc-shaped strip through the lateral wheel, allowing liquid to enter the liquid storage shell. At this time, the autonomous expansion and positioning assembly automatically expands to position the thin-walled shell.

[0009] The liquid storage shell is equipped with a water conveying assembly inside. A spray assembly is connected to the top of the water conveying assembly. The spray assembly is located inside the self-expanding positioning assembly. The water conveying assembly moves to the raised part of the annular plate through the moving wheels, so that the water conveying assembly sprays water upward through the spray assembly and cools the thin-walled shell through heat exchange via the self-expanding positioning assembly.

[0010] Preferably, the polishing assembly includes a fixing frame, which is fixedly connected to the bottom shell. An electric push rod is fixedly installed above the fixing frame, and a polishing machine is installed at the bottom end of the electric push rod.

[0011] Preferably, the feeding assembly includes a motor, which is fixedly installed in the bottom shell. The output shaft of the motor is fixedly connected to a feeding disc, which is rotatably mounted on the bottom shell via bearings.

[0012] Preferably, the support assembly includes a support plate, which is mounted on the feeding tray, the liquid storage shell is mounted on the support plate, and four limiting blocks are fixedly connected above the support plate.

[0013] Preferably, two support wheels are fixedly connected to the bottom of the support plate, and a horizontal plate is fixedly connected between the two support wheels, with the support wheels rolling on the bottom wall of the bottom shell.

[0014] Preferably, the active hydraulic component includes a housing, which is fixedly connected to a transverse plate, and the housing is connected to a liquid storage tank via a pipe;

[0015] A first piston is provided in the outer casing, and an extension rod is fixedly connected to one side of the first piston. The extension rod extends out of the outer casing and is fixedly connected to a transverse wheel. A first spring is fixedly connected between the first piston and the outer casing.

[0016] Preferably, a refrigeration component is installed inside the liquid storage tank.

[0017] Preferably, the self-expanding positioning component includes a double-layer rubber airbag, which is installed above the liquid storage shell. The double-layer rubber airbag is disposed in a thin-walled shell, and multiple temperature-conducting columns are provided in the double-layer rubber airbag. Supporting material is filled in the same space as the double-layer airbag and the temperature-conducting columns.

[0018] Preferably, the spray assembly includes a connector and a horizontal plate. The horizontal plate is rotatably mounted on the connector via a bearing and is connected to the connector. Multiple spray heads are tangentially arranged on the horizontal plate, and a spray head structure is connected above the horizontal plate.

[0019] Preferably, the water delivery assembly includes a water delivery cylinder, which is fixedly installed in the liquid storage shell. A one-way valve is installed below the water delivery cylinder. A second one-way pipe and a one-way drainage pipe are connected above the water delivery cylinder. The one-way drainage pipe extends downward to the lower part of the inner cavity of the liquid storage shell. The second one-way pipe is connected to a connector, which is installed at the top of the water delivery cylinder and is connected to a first one-way pipe. The first one-way pipe is connected to the lower part of the water delivery cylinder.

[0020] The water delivery cylinder is equipped with a second piston inside. A second spring is fixedly connected between the second piston and the bottom wall of the water delivery cylinder. A piston rod is fixedly connected below the second piston. The piston rod extends out of the water delivery cylinder and is fixedly connected to the moving wheel.

[0021] Compared with the prior art, the present invention provides a thin-walled shell surface treatment device for manufacturing photovoltaic prefabricated cabins, which has the following beneficial effects:

[0022] 1. This thin-walled shell surface treatment equipment for photovoltaic prefabricated cabin manufacturing uses a feeding assembly to drive a support assembly to rotate, thereby moving the support assembly to the position of the thin-walled shell and allowing it to reach the grinding area for smooth surface treatment. The uniform transfer of the thin-walled shell enables continuous processing, and the alternating switching of multiple support assemblies ensures continuous feeding and achieves multi-station synchronization. Furthermore, the movement of the feeding assembly moves the transverse wheel onto the arc-shaped strip. At this point, the active hydraulic assembly inputs liquid into the storage tank, causing the liquid inside to rise and press the gas above upwards. This causes the double-layered rubber airbag to expand and fit against the inner cavity of the thin-walled shell, providing excellent internal support and reducing the risk of thermal deformation during surface treatment.

[0023] 2. This thin-walled shell surface treatment equipment for photovoltaic prefabricated cabin manufacturing uses a feeding assembly to rotate, causing the moving wheels to follow and move to the raised part. This allows the water conveying assembly to draw liquid from inside the storage tank and continuously spray it onto the double-layered rubber airbags via the spraying assembly. The double-layered rubber airbags facilitate heat exchange in the thin-walled shell, and the heat-conducting columns further enhance the heat exchange effect, making it easier to cool the surface-treated workpiece. This method effectively cools the thin-walled shell, reduces equipment usage, lowers overall costs, and facilitates subsequent material handling after cooling. Furthermore, the sprayed liquid can be returned to the storage tank, ensuring liquid recycling.

[0024] 3. This thin-walled shell surface treatment equipment for photovoltaic prefabricated cabin manufacturing uses a feeding assembly to drive the support assembly to rotate and feed materials. When one end of the active hydraulic assembly moves onto the arc-shaped strip, the active hydraulic assembly inputs liquid into the storage tank, increasing the liquid volume and allowing gas to be lifted into the double-layer rubber airbag. The double-layer rubber airbag expands and fits into the inner cavity of the thin-walled shell, achieving the positioning of the thin-walled shell. Secondly, when the water conveying assembly moves to the raised part, it can spray liquid upwards through the spraying assembly. Because the double-layer rubber airbag fits into the inner cavity of the thin-walled shell, it is more conducive to the heat exchange and cooling operation of the thin-walled shell. Moreover, since the support material is polyvinyl alcohol hydrogel, the material hardens when the temperature is below 10℃. In the heat exchange process, the support material hardens, which can effectively shape the double-layer rubber airbag and further ensure the stability of the support for the thin-walled shell, making the thin-walled shell less prone to deformation.

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Example 1: Refer to Figures 1-9 A thin-walled shell surface treatment device for manufacturing photovoltaic prefabricated cabins includes a thin-walled shell surface treatment mechanism 100, and a plurality of grinding auxiliary mechanisms 200 are provided on the thin-walled shell surface treatment mechanism 100.

[0040] The thin-walled shell surface treatment mechanism 100 includes a base shell 101 and a grinding assembly 102. The grinding assembly 102 includes a fixing frame 1021, which is fixedly connected to the base shell 101. An electric push rod 1022 is fixedly installed above the fixing frame 1021, and a grinding machine 1023 is installed at the bottom end of the electric push rod 1022. The fixing frame 1021 can control the electric push rod 1022, ensuring its stability and allowing the electric push rod 1022 to smoothly adjust the position of the grinding machine 1023, thereby enabling the grinding machine 1023 to smoothly grind the thin-walled shell. The shell is subjected to surface grinding. A feeding assembly 103 is provided in the bottom shell 101. The feeding assembly 103 includes a motor 1031, which is fixedly installed in the bottom shell 101. The output shaft of the motor 1031 is fixedly connected to a feeding disc 1032. The feeding disc 1032 is rotatably mounted on the bottom shell 101 through bearings. The motor 1031 drives the feeding disc 1032 to rotate, which in turn drives the grinding auxiliary mechanism 200 to rotate, thereby driving the thin-walled shell to perform feeding operations. An arc-shaped strip 105 is fixedly connected to the side wall of the bottom shell 101.

[0041] The grinding auxiliary mechanism 200 includes a support assembly 201, which includes a support plate 2011 mounted on the feeding disc 1032. A liquid storage shell 203 is mounted on the support plate 2011. Four limiting blocks 2013 are fixedly connected to the top of the support plate 2011. The support plate 2011 ensures the placement of the thin-walled shell, and the limiting blocks 2013 correspond to the four corners of the thin-walled shell, thus enabling precise alignment and positioning of the thin-walled shell. Two support wheels 2012 are fixedly connected to the bottom of the support plate 2011, supporting the support plate 2011 and assisting the support disc and feeding disc 1032 in smooth movement. A transverse plate 2014 is fixedly connected between the two support wheels 2012. The support wheels 2012 roll on the bottom wall of the bottom shell 101. The support assembly 201 is used to place the thin-walled shell. An active hydraulic assembly 202 is provided on the upper part. The active hydraulic assembly 202 includes a housing 2021, which is fixedly connected to the transverse plate 2014. The housing 2021 is connected to the liquid storage shell 203 through a pipe. A first piston 2025 is provided in the housing 2021. An extension rod 2022 is fixedly connected to one side of the first piston 2025. The extension rod 2022 extends out of the housing 2021 and is fixedly connected to the transverse wheel 2023. By rolling the transverse wheel 2023, the movement resistance between the transverse wheel and the arc strip 105 can be reduced. The transverse wheel 2023 moves the arc surface position of the arc strip 105. As the arc surface curvature increases, the transverse wheel 2023 can move. The transverse wheel 2023 can drive the first piston 2025 to move through the extension rod 2022, so that the liquid enters the liquid storage shell 203. In turn, the gas above the liquid storage shell 203 can be pressed into the double-layer rubber airbag 2051, so that the double-layer rubber airbag 2051 supports the thin-walled shell.

[0042] A first spring 2024 is fixedly connected between the first piston 2025 and the outer shell 2021. The first spring 2024 drives the first piston 2025 to return to its original position, allowing the first piston 2025 to introduce liquid from the reservoir 203 into the outer shell 2021. The active hydraulic component 202 is connected to the reservoir 203. A cooling component 204 is installed inside the reservoir 203 to cool the returning liquid, thereby ensuring continuous use of the liquid. The reservoir 203 is mounted on the support component 201. A self-expanding positioning component 205 is connected above the reservoir 203. The self-expanding positioning component 205 includes a double-layer rubber airbag 2051, which is expandable. Furthermore, the gas can be expanded into a double-layer rubber airbag 2051, which can smoothly support the thin-walled shell. The double-layer rubber airbag 2051 is installed above the liquid storage shell 203 and is located in the thin-walled shell. Multiple temperature-conducting columns 2052 are provided in the double-layer rubber airbag 2051. The temperature-conducting columns 2052 can increase the temperature conduction points, thereby facilitating heat exchange and improving the cooling effect on the thin-walled shell. The double-layer airbag and the temperature-conducting columns 2052 are filled with support material 2053 in the same space. The horizontal wheel 2023 of the active hydraulic component 202 moves to the arc-shaped bar 105, so that the liquid is input into the liquid storage shell 203. At this time, the self-expansion positioning component 205 automatically expands to position the thin-walled shell.

[0043] The liquid storage shell 203 is equipped with a water conveying assembly 206. The top of the water conveying assembly 206 is connected to a spray assembly 207. The spray assembly 207 is located inside the self-expanding positioning assembly 205. The water conveying assembly 206 moves to the raised part 106 of the annular plate 104 via the moving wheels 2066, so that the water conveying assembly 206 sprays upward through the spray assembly 207, and the thin-walled shell is cooled by heat exchange through the self-expanding positioning assembly 205.

[0044] In this embodiment: the feeding disc 1032 is driven to rotate by the motor 1031, and the feeding disc 1032 drives the support plate 2011 to rotate, so that the support plate 2011 moves the position of the thin-walled shell, so that the thin-walled shell reaches the grinding area, and the surface treatment operation can be carried out smoothly. The uniform speed transfer of the thin-walled shell can realize continuous processing operation, and the alternating switching of multiple support components 201 can also meet the continuous feeding and achieve the effect of multi-station synchronization. Secondly, the movement of the feeding component 103 causes the transverse wheel 2023 to move onto the arc strip 105. At this time, the transverse wheel 2023 is squeezed by the arc strip 105 to move the extension rod 2022, and the first piston 2025 moves to input liquid into the liquid storage shell 203. The liquid inside the liquid storage shell 203 rises, which in turn can push the gas above upward, causing the double-layer rubber air bag 2051 to expand and fit into the inner cavity of the thin-walled shell, thereby providing a good internal support for the thin-walled shell, thereby reducing the problem of thermal deformation that easily occurs when the thin-walled shell is subjected to surface treatment.

[0045] Example 2: Refer to Figure 7 and Figures 9-11 A surface treatment device for thin-walled shells used in the manufacture of photovoltaic prefabricated cabins includes a spray assembly 207. The spray assembly 207 includes a connector 2071 and a horizontal plate 2072. The horizontal plate 2072 is rotatably mounted on the connector 2071 via bearings. The horizontal plate 2072 can maintain stable rotational movement through the bearings, and the horizontal plate 2072 is connected to the connector 2071. Multiple spray heads 2073 are tangentially arranged on the horizontal plate 2072. Through the tangential design of the spray heads 2073, the impact force generated by the sprayed liquid can smoothly drive the device. The horizontal plate 2072 rotates, thereby increasing the spray area on the double-layer rubber airbag 2051 while maintaining the uniformity of spraying, which facilitates heat exchange operations. The top of the horizontal plate 2072 is connected to the nozzle structure 2074. An annular plate 104 is fixedly connected to the bottom wall of the bottom shell 101. The annular plate 104 is provided with two continuous raised parts 106. Through the design of the raised parts 106, the moving wheel 2066 can squeeze and smoothly drive the first piston 2025 to move, thereby facilitating the upward water conveyance operation of the first piston 2025.

[0046] The autonomous expansion positioning component 205 includes a double-layer rubber airbag 2051, which is installed above the liquid storage shell 203. The double-layer rubber airbag 2051 is located in a thin-walled shell and has multiple temperature-conducting columns 2052.

[0047] The water delivery assembly 206 includes a water delivery cylinder 2061, which is fixedly installed in the liquid storage shell 203. A one-way valve 2062 is installed below the water delivery cylinder 2061. The one-way valve 2062 and the one-way drainage pipe 2069 maintain one-way water inflow, preventing liquid backflow. The one-way valve 2062, in conjunction with the one-way drainage pipe 2069, allows for switching the drainage operation up and down. A second one-way pipe 2068 and the one-way drainage pipe 2069 are connected above the water delivery cylinder 2061. The one-way drainage pipe 2069 extends downwards to the lower part of the inner cavity of the liquid storage shell 203. The second one-way pipe 2068 communicates with a connector 2071, which is installed at the top of the water delivery cylinder 2061 and communicates with a first one-way pipe 2067. The first one-way pipe 2067 and the second one-way pipe 2068 maintain one-way water outflow. The first one-way pipe 2067 and the second one-way pipe 2068 work together to switch the water outlet up and down. The first one-way pipe 2067 is connected to the lower part of the water delivery cylinder 2061. The water delivery cylinder 2061 is equipped with a second piston 2063. A second spring 2064 is fixedly connected between the second piston 2063 and the bottom wall of the water delivery cylinder 2061. The second spring 2064 can drive the second piston 2063 to return to its original position downwards, so that the second piston 2063 can push the liquid in the lower cavity of the water delivery cylinder 2061 out through the first one-way pipe 2067. A piston rod 2065 is fixedly connected to the lower part of the second piston 2063. The piston rod 2065 extends out of the water delivery cylinder 2061 and is fixedly connected to the moving wheel 2066. The rolling property of the moving wheel 2066 can reduce the movement resistance with the raised part 106 and maintain the smooth movement of the moving wheel 2066.

[0048] In this embodiment: the feeding assembly 103 rotates, causing the moving wheel 2066 to move to the raised portion 106. The moving wheel 2066 drives the piston rod 2065 and the second piston 2063. The second piston 2063 draws liquid through the one-way valve 2062 and forces the liquid into the connector 2071 through the second one-way pipe 2068. When the moving wheel 2066 moves to the recess of the raised portion 106, the second spring 2064 drives the second piston 2063 to reset, allowing the liquid to be output through the first one-way pipe 2067. The second piston 2063 also introduces liquid into the water delivery cylinder 206 through the one-way drainage pipe 2069. The liquid output from the upper chamber of 1 enters the horizontal plate 2072. Due to the tangential design of the spray head 2073, the spray head 2073 rotates to spray. The liquid is also sprayed onto the double-layer rubber air bag 2051 through the spray head structure 2074. The double-layer rubber air bag 2051 then facilitates heat exchange in the thin-walled shell. The heat-conducting column 2052 can increase the heat exchange effect, making it easier to cool down the surface-treated workpiece. This method can effectively cool down the thin-walled shell, reduce equipment usage, lower overall costs, and facilitate subsequent material handling after cooling. Furthermore, the sprayed liquid can be returned to the liquid storage tank 203, thus ensuring the recycling of the liquid.

[0049] Example 3: Reference Figures 2-7 A thin-walled shell surface treatment device for manufacturing photovoltaic prefabricated cabins includes a thin-walled shell surface treatment mechanism 100. The thin-walled shell surface treatment mechanism 100 includes a bottom shell 101 and a grinding assembly 102. A feeding assembly 103 is provided in the bottom shell 101. An arc-shaped strip 105 is fixedly connected to the side wall of the bottom shell 101. An annular plate 104 is fixedly connected to the bottom wall of the bottom shell 101. Two continuous protrusions 106 are provided on the annular plate 104.

[0050] The grinding auxiliary mechanism 200 includes a support component 201, which is used to place the thin-walled shell. An active hydraulic component 202 is provided on the support component 201. The active hydraulic component 202 is connected to the liquid storage shell 203, which is located on the support component 201. An autonomous expansion positioning component 205 is connected above the liquid storage shell 203. The active hydraulic component 202 moves to the arc-shaped bar 105 through the transverse wheel 2023, so that liquid is input into the liquid storage shell 203. At this time, the autonomous expansion positioning component 205 automatically expands to position the thin-walled shell.

[0051] The liquid storage shell 203 is equipped with a water conveying assembly 206. The top of the water conveying assembly 206 is connected to a spray assembly 207. The spray assembly 207 is located inside the self-expanding positioning assembly 205. The water conveying assembly 206 moves to the raised part 106 of the annular plate 104 via the moving wheels 2066, so that the water conveying assembly 206 sprays upward through the spray assembly 207, and the thin-walled shell is cooled by heat exchange through the self-expanding positioning assembly 205.

[0052] In this embodiment: the feeding component 103 drives the support component 201 to rotate and feed material. When one end of the active hydraulic component 202 travels onto the arc-shaped bar 105, the active hydraulic component 202 inputs liquid into the liquid storage shell 203, increasing the liquid volume and lifting the gas into the double-layer rubber airbag 2051. The double-layer rubber airbag 2051 expands and fits into the inner cavity of the thin-walled shell, achieving the positioning of the thin-walled shell. Secondly, the water conveying component 206 travels to the raised part 106 and can spray liquid upward through the spraying component 207. Since the double-layer rubber airbag 2051 fits into the inner cavity of the thin-walled shell, it is more conducive to the heat exchange and cooling operation of the thin-walled shell. Moreover, since the support material 2053 is polyvinyl alcohol hydrogel, the material hardens when the temperature is below 10°C. In the heat exchange, the support material 2053 hardens, which can effectively shape the double-layer rubber airbag 2051 and further ensure the stability of the support for the thin-walled shell, making the thin-walled shell less prone to deformation.

[0053] Working principle: When treating the surface of the thin-walled shell of the photovoltaic prefabricated cabin, the thin-walled shell is placed on the support plate 2011, and the limiting block 2013 positions the thin-walled shell. Then, the motor 1031 drives the feeding plate 1032 to rotate, and the grinding auxiliary mechanism 200 rotates with the feeding plate 1032. When the transverse wheel 2023 moves to the arc strip 105, the arc surface of the arc strip 105 presses the transverse wheel 2023 to move. The transverse wheel 2023 drives the extension rod 2022 to move. The extension rod 2022 drives the first piston 2025 to move. The first piston 2025 drives the first spring 2024 to deform, and the first piston 2025 inputs the liquid in the outer shell 2021 into the liquid storage shell 203. As the liquid increases, the gas above the liquid storage shell 203 continuously enters the double-layer rubber airbag 2051. The double-layer rubber airbag 2051 expands and inflates, so that the double-layer rubber airbag 2051 adheres to the inner cavity of the thin-walled shell for retention.

[0054] Subsequently, the movable wheel 2066 moves to the raised portion 106, causing the movable wheel 2066 to drive the piston rod 2065 to rise. The piston rod 2065 drives the second piston 2063 to rise, and the second piston 2063 causes the second spring 2064 to deform. The second piston 2063 draws liquid from the inside of the liquid storage shell 203 through the one-way valve 2062, and pushes the liquid above the second piston 2063 into the connector 2071 through the second one-way tube 2068. When the movable wheel 2066 moves to the recess between the two raised portions 106, the second spring 2064 drives the piston to return to its original position. At this time, liquid is introduced into the upper cavity of the water supply cylinder 2061 through the one-way drainage pipe 2069, and the second piston 2063 can also input liquid into the connector 2071 again through the first one-way pipe 2067. In this way, through the raised part 106, the water supply component 206 continuously supplies water upward, and then enters the horizontal plate 2072 to spray out. The spray head 2073 is tangentially designed so that it can rotate to spray. At the same time, the spray head structure 2074 sprays liquid synchronously, so that the liquid is sprayed into the inner cavity of the double-layer rubber air bag 2051, and the support material 2053 hardens to shape the double-layer rubber air bag 2051.

[0055] Secondly, since the electric push rod 1022 pre-adjusts the grinding machine 1023 to a suitable position, the thin-walled shell can be surface-treated by the grinding machine 1023. Since the grinding and spraying operations are carried out simultaneously, the heat generated during the grinding process can be exchanged and cooled by the double-layer rubber airbag 2051. After cooling, the liquid flows back to the liquid storage shell 203 and is further cooled by the cooling component 204. The thin-walled shell continues to be conveyed. When the moving wheel 2066 disengages from the arc strip 105, the first spring 2024 drives the first piston 2025 to reset, so that the liquid flows back to the outer shell 2021. When the thin-walled shell is conveyed to the initial position, the thin-walled shell is then taken out. The feeding component 103 drives the support component 201 to switch movements, thereby enabling continuous processing of the thin-walled shell.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
