Multiple sets of blades are spirally arranged on the outside of the inner cylinder and fixedly connected to the inner cylinder. The inner cylinder is arranged inside the outer cylinder and rotatably connected to the outer cylinder. Two adjacent blades, the inner cylinder, and the outer cylinder form an airflow channel. The air jet orifice is opened on the inner cylinder and communicates with the airflow channel. The air jet orifice can spray air relative to the tube blank.

[0007] A cooling system is provided on the outer cylinder, which can input cold air into each of the airflow channels to supply air to the airflow channels and drive the inner cylinder to rotate.

[0008] Furthermore, the plurality of jet holes are equidistantly arranged along the helical trajectory of the blade.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0029] This embodiment describes an air-cooling device for an RTP tube, which relates to the field of RTP tube processing technology. By providing blades 123 between the inner cylinder 121 and the outer cylinder 110, gas can drive the blades 123 to rotate the inner cylinder 121 relative to each other, thereby uniformly cooling the tube blank located in the inner cylinder 121. This results in uniform cooling of the tube blank, increases the cooling speed, and promotes the forming of the tube blank.

[0030] Please see Figures 1 to 6 The air-cooling device for RTP tube in this embodiment includes an air-cooling cylinder 100 and a cooling system 200. The air-cooling cylinder 100 can uniformly cool the tube blank, and the cooling system 200 can cool the delivered air, thereby increasing the cooling speed and promoting the forming of the tube blank.

[0031] The air-cooled cylinder 100 includes an outer cylinder 110 and an air-cooling unit 120. The air-cooling unit 120 includes an inner cylinder 121, jet nozzles 122, and blades 123. Multiple sets of blades 123 are spirally arranged on the outside of the inner cylinder 121, and the inner sides of the blades 123 are fixedly connected to the inner cylinder 121. The inner cylinder 121 is enclosed within the outer cylinder 110 and rotatably connected to the outer cylinder 110. The outer cylinder 110 is fixed and serves as an integral support structure, isolating external interference. The inner cylinder 121 is rotatably connected to the outer cylinder 110 and can rotate with the airflow. Adjacent blades 123, the inner cylinder 121, and the outer cylinder 110 form an airflow channel. The jet nozzles 122 are opened on the inner cylinder 121 and communicate with the airflow channel. The airflow in each airflow channel can pass through the jet nozzles 122 to clean the tube blank. The airflow flowing along the airflow channel can act on the blades 123, driving the inner cylinder 121 to rotate relative to each other, so that the position of the jet hole 122 can rotate relative to the tube blank, so that the cold air continuously changes the jet angle, avoiding the generation of uneven cold and hot spots, and achieving 360° uniform cooling.

[0032] The cooling system 200 is installed on the outer cylinder 110. The cooling system 200 can supply air independently to each airflow channel. The generated supercooled air can drive the inner cylinder 121 to rotate relative to each other, and can also cool the tube blank through the jet hole 122.

[0033] In some embodiments, please refer to Figure 2 and Figure 3 Multiple jet holes 122 are equidistantly arranged along the spiral trajectory of the blades 123. The arrangement of the spiral trajectory of the blades 123 ensures that the jet holes 122 provide uniform airflow coverage along the surface of the tube blank, avoiding cooling dead zones caused by concentrated or uneven airflow distribution in traditional air-cooled systems. The cold air from each jet hole 122 is evenly sprayed onto the tube surface in a spiral manner, ensuring that no cooling area is missed.

[0034] Meanwhile, the jet holes 122 are equidistantly arranged along the spiral trajectory, which optimizes the cold air jet angle and airflow path, effectively increasing the contact time between the airflow and the pipe surface and improving the cooling efficiency. The cooling effect is even more significant for the tube blank part with a large heat capacity.

[0035] Uniform cooling allows the tube blank to enter the shaping stage more stably, reducing shape defects or degradation of physical properties caused by uneven cooling. Especially in the production of RTP tubes, the difference in cooling rate between the inside and outside of the tube wall affects the final molding quality, and the equidistant jet hole 122 design helps to optimize this process.

[0036] In some embodiments, the side of the blade 123 away from the inner cylinder 121 is spaced apart from the inner wall of the outer cylinder 110. This gap provides an airflow channel, allowing sufficient space for the airflow to expand and distribute evenly as it flows between the inner cylinder 121 and the outer cylinder 110. Because of this gap, the airflow does not create unnecessary resistance at the edge of the blade 123, avoiding localized airflow turbulence and improving airflow stability.

[0037] By designing an appropriate gap between the blade 123 and the inner wall of the outer cylinder 110, friction and resistance of the airflow can be reduced. The airflow can flow relatively smoothly through this gap to the surface of the tube blank, avoiding compression or local stall of the airflow.

[0038] In some embodiments, please continue reading Figure 2 and Figure 3 Both ends of the outer cylinder 110 are provided with flanges 111. The flanges 111 can effectively enhance the firmness of the connection between the inner and outer cylinders 110 and prevent loosening or misalignment between the inner and outer cylinders 110 during rotation or use. Since the flanges 111 of the outer cylinder 110 form a natural positioning structure, the inner cylinder 121 maintains a fixed and stable relative position within the outer cylinder 110.

[0039] The flange 111 is connected to the inner cylinder 121 via a sealed bearing. The use of the sealed bearing further improves the sealing between the inner cylinder 121 and the outer cylinder 110, preventing airflow leakage in the channel. The sealed bearing not only ensures the smooth rotation of the inner cylinder 121, but also ensures that the cooling airflow flows completely along the airflow channel without leakage from the connection point, thereby improving the cooling effect.

[0040] By using sealed bearings, the connection between the inner cylinder 121 and the outer cylinder 110 becomes smoother, reducing wear caused by friction. Sealed bearings provide low-friction rotation, ensuring that the inner cylinder 121 does not generate unnecessary heat and loss during rotation, thus extending the system's service life.

[0041] The combination of the flange 111 and the sealed bearing effectively prevents external impurities, dust, or other contaminants from entering the space between the inner and outer cylinders 110. Maintaining the cleanliness of the internal channels ensures smooth airflow for cooling, preventing a decrease in cooling efficiency or equipment damage due to the accumulation of contaminants.

[0042] In some embodiments, please refer to Figures 2 to 4The cooling system 200 includes a cooling unit 210, an air duct 220, and multiple connectors 230. The connectors 230 are equidistantly arranged around the central axis of the outer cylinder 110 and are connected to the flange 111, allowing airflow to be evenly distributed into each airflow channel. This avoids concentrated or uneven distribution of cold air, ensuring sufficient and uniform cooling for every area of ​​the tube blank. The two ends of the air duct 220 are connected to the cooling unit 210 and the connectors 230, respectively. The cooling unit 210 is connected to the airflow channels via the air duct 220 and the connectors 230, enabling efficient connection and airflow control between the cooling unit 210 and the airflow channels. The cooling unit 210 delivers cold air to the multiple connectors 230 through the air duct 220, and then evenly distributes the cold air into each airflow channel, forming an orderly and continuous cooling process.

[0043] The air duct 220 can adjust the air pressure and volume as needed to ensure that the cooling effect remains stable under different production conditions.

[0044] Multiple connectors 230 are equidistantly arranged around the central axis of the outer cylinder 110, allowing airflow to be evenly distributed into each airflow channel. This avoids the concentration or uneven distribution of cold air, ensuring that every area of ​​the tube blank receives sufficient and uniform cooling.

[0045] In some embodiments, please refer to Figure 6 The cooling unit 210 includes a water tank 211, a spiral coil 212, and a fan 213. The spiral coil 212 is submerged in the water tank 211, where the water acts as a cooling medium and transfers heat through the surface of the spiral coil 212. This combination of the spiral coil 212 and the water tank 211 allows for effective heat transfer from the cooling water flowing through the spiral coil 212, accelerating the heat exchange process and significantly improving cooling efficiency.

[0046] Water, as a cooling medium, has a high specific heat capacity, allowing it to absorb a large amount of heat in a short time, thus making the cooling effect more significant. The spiral coil 212 design also increases the contact area between the water and the heat source, further enhancing the cooling capacity.

[0047] The two ends of the spiral coil 212 are connected to the fan 213 and the air duct 220, respectively. By cooperating the cooling medium (water) with the spiral coil 212 and the fan 213, the cooling unit 210 simplifies the use of redundant components such as cooling water pumps and cooling pipes in the traditional cooling system 200. The entire cooling system 200 achieves heat exchange through the spiral coil 212 and the water tank 211, reducing the complexity of the system and the difficulty of maintenance.

[0048] The cooling intensity can be flexibly controlled by adjusting the speed of the fan 213 and the flow rate of the cooling water. The combination of the spiral coil 212 and the water tank 211 ensures more precise adjustment of the cooling intensity, thereby meeting the requirements of cooling temperature and speed in different production processes.

[0049] In some embodiments, please refer to Figure 1 A multi-way adapter 240 is provided between the spiral coil 212 and the air duct 220. One end of the multi-way adapter 240 is connected to the spiral coil 212, and the other end of the multi-way adapter 240 is connected to multiple air ducts 220 respectively.

[0050] The multi-port adapter 240 allows cooling airflow to be evenly distributed into multiple air ducts 220, ensuring uniform distribution of cooling airflow in multiple airflow channels. In this way, cooling air can be evenly delivered to multiple connectors 230 and airflow channels, avoiding the concentration of cooling air in certain areas and improving the overall efficiency of the cooling system 200.

[0051] The multi-port adapter 240 distributes cooling airflow evenly, preventing airflow concentration within a single air duct 220 and reducing airflow resistance and pressure loss in localized areas. Compared to a traditional single air duct 220 system, multiple parallel air ducts 220 effectively reduce pressure fluctuations in the system, making the cooling system 200 more stable and reducing the load on the fan 213.

[0052] An air-cooling device for RTP tubes also includes supports 300. Two supports 300 are connected to both ends of the outer cylinder 110, respectively. The function of the supports 300 is to stabilize and support the outer cylinder 110, ensuring the stability of the entire air-cooling device during operation. The outer cylinder 110 typically bears a certain amount of wind pressure and mechanical force. The supports 300 distribute this force to both ends of the device, preventing the outer cylinder 110 from deforming or shifting due to excessive load. The connection of the supports 300 makes the overall structure of the air-cooling device more robust and able to withstand greater mechanical stress, especially under the stability requirements of high-speed rotation and cooling processes.

[0053] Workflow: First, the blower 213 is started, and the cold air cooled by the water tank 211 is input into multiple connectors 230. The multiple connectors 230 are set with different airflow channels. The cold air is sprayed out from the jet hole 122 while driving the inner cylinder 121 to rotate. Then, the initially formed tube blank gradually passes through the inner cavity of the inner cylinder 121. The rotating and sprayed cold air can uniformly cool the tube blank and promote the rapid cooling and forming of the tube blank.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
