Description

Technical Field

[0002] A cooling water circulation device for an electrothermal extruder is an auxiliary device specifically designed for controlling temperature and ensuring stable operation of this type of extruder. Its main task is to remove excess heat generated during the extrusion process, thereby preventing overheating of the barrel, heating zone, or electrothermal jacket, and ensuring the quality of plastic melt and equipment safety.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5A cooling water circulation device for an electrothermal melt-sleeve extruder includes a main body 1, an installation mechanism, and an internal circulation mechanism. The installation mechanism includes a cooling pipe 2, a heat-conducting frame 3, a contact pipe 4, an inner tube 5, and a fixing component. Both ends of the cooling pipe 2 are fixedly connected to the main body 1. The heat-conducting frame 3 is installed inside the cooling pipe 2 and is connected to the cooling pipe 2. The contact pipe 4 is installed inside the heat-conducting frame 3 and is rotatably connected to the heat-conducting frame 3. The inner tube 5 is installed inside the contact pipe 4 and is connected to the contact pipe 4. The fixing component includes a fixing frame 6, an installation frame 7, and a spring 8. The fixing frame 6 is installed on the contact pipe 4 and is slidably connected to the contact pipe 4. The installation frame 7 is installed on the main body 1 and is slidably connected to the main body 1 and threadedly engaged with the contact pipe 4. The spring 8 is fixedly installed inside the contact pipe 4, and its other end is fixedly connected to the fixing frame 6.

[0031] In this embodiment, the mounting mechanism includes a cooling pipe 2, a heat-conducting frame 3, a contact pipe 4, an inner tube 5, and a fixing assembly. In use, the main body 1 is first installed onto the cylindrical heating pipe on the extruder. Then, the heat-conducting frame 3 is installed into the connecting groove 17 of the connecting frame 16. During the installation of the heat-conducting frame 3, the contact pipe 4 is also installed. The mounting bracket 7 can then be installed on one end of the connecting groove 17. The heat-conducting frame 3 is then fixed, and the fixing bracket 6 is pulled, causing the fixing bracket 6 to slide on the contact pipe 4 and compress the spring 8. The contact pipe 4 can then be rotated so that the external thread 20 at one end of the contact pipe 4 engages with the threaded hole 21 on the mounting bracket 7. Finally, the heat-conducting frame 3 is released, and the fixing bracket 7 is rotated continuously. After the external thread 20 and threaded hole 21 are connected, the fixed bracket 6 can be adjusted so that the positioning rod 19 on the fixed bracket 6 is directly aligned with the positioning hole 18 on the heat conduction frame 3. Then the fixed bracket 6 is released so that the positioning rod 19 is connected with the positioning hole 18 again, thereby fixing the position of the contact tube 4. This prevents the connection with the mounting bracket 7 from being interrupted due to vibration during mechanical operation. If the contact tube 4 cannot contact the heating tube on the extruder, an embedded tube 5 can be installed on the heating tube so that the embedded tube 5 contacts the heating tube and the contact tube 4 to complete the temperature transfer. All of the above components, including the contact tube 4, the connecting bracket 16, and the embedded tube 5, are made of heat-conducting materials.

[0032] In this embodiment, the internal circulation mechanism includes a water tank 9, a flow guide 10, a fan 11, and a temperature guide frame 12. During use, the heating pipe operates, the temperature rises, and the booster pump 22 installed on the main body 1 starts running. The connecting pipe 23 at the bottom of the booster pump directly pressurizes the coolant in the water tank 9 into the cooling pipe 2, allowing the coolant to flow more rapidly in the cooling pipe 2. However, if the coolant doesn't dissipate heat over time, the temperature of the coolant in the water tank 9 will rise. At this time, the fan 11 installed in the mounting slot 24 inside the main body 1 starts running. The fans 11 on both sides of the main body 1 rotate in the same direction, which can guide the flow... Outside air is drawn into component 10, passes through the temperature guide plate 25 on the temperature guide frame 12, and is discharged into the flow guide component 10, finally entering the air. Under the action of the flow guide component 10, the incoming air and the outgoing air will not mix, thus not raising the temperature of the surrounding air, so that the temperature inside the water tank 9 can be effectively maintained. Moreover, if it is necessary to change to a different type of coolant, the coolant can be drawn out from the drain pipe 15 of the water tank 9 and refilled into the inlet pipe 14. Furthermore, under the action of the support frame 13, the height of the water tank 9 and the main body 1 can be the same as the heating pipe of the corresponding extruder.

[0033] Example 2:

[0034] In summary, during use, the main body 1 needs to be installed onto the cylindrical heating tube on the extruder first. Then, the heat-conducting frame 3 can be installed into the connecting groove 17 of the connecting frame 16. During the installation of the heat-conducting frame 3, the contact tube 4 is also installed. At this point, the mounting bracket 7 can be installed on one end of the connecting groove 17. The heat-conducting frame 3 can be fixed first, and then the fixing bracket 6 can be pulled, causing the fixing bracket 6 to slide on the contact tube 4 and compress the spring 8. The contact tube 4 can then be rotated so that the external thread 20 at one end of the contact tube 4 engages with the threaded hole 21 on the mounting bracket 7. Then, the heat-conducting frame 3 is released, and the fixing bracket 6 is rotated continuously. After the external thread 20 and threaded hole 21 are properly connected, the fixing bracket 6 can be adjusted so that the positioning rod 19 on the fixing bracket 6 is directly aligned with the positioning hole 18 on the heat conduction bracket 3. Then, the fixing bracket 6 is released, allowing the positioning rod 19 to reconnect with the positioning hole 18, thus fixing the position of the contact tube 4. This prevents the connection with the mounting bracket 7 from being interrupted due to vibration during mechanical operation. If the contact tube 4 does not contact the heating tube on the extruder, an inner tube 5 can be installed on the heating tube, allowing the inner tube 5 to contact both the heating tube and the contact tube 4, completing the temperature transfer. The contact pipe 4, connecting frame 16, and embedded pipe 5, among other components, are all made of thermally conductive materials, while the flow guide 10 is made of thermally insulating material. During device operation, the heating pipes work, the temperature rises, and the booster pump 22 installed on the main body 1 starts operating. The connecting pipe 23 at the bottom of the booster pump directly pressurizes the coolant in the water tank 9 and directs it into the cooling pipe 2, allowing the coolant to flow more rapidly within the cooling pipe 2. However, if the coolant doesn't dissipate heat over time, the temperature of the coolant in the water tank 9 will rise. At this point, the fan 11 installed in the mounting slot 24 inside the main body 1 starts operating. The fans 11 on both sides of the main body 1 rotate in the same direction. Outside air can be drawn in through the guide member 10, discharged into the guide member 10 after passing through the temperature guide plate 25 on the temperature guide frame 12, and finally enter the air. Under the action of the guide member 10, the incoming air and the outgoing air will not mix, thus not raising the temperature of the surrounding air, so that the temperature inside the water tank 9 can be effectively maintained. Moreover, if it is necessary to change to a different type of coolant, the coolant can be drawn out through the drain pipe 15 of the water tank 9 and refilled through the inlet pipe 14. Furthermore, under the action of the support frame 13, the height of the water tank 9 and the main body 1 can be the same as the heating pipe of the corresponding extruder.

For all the fixed connections mentioned above, welding is preferred.
