Description

Technical Field

[0001] This disclosure relates to the field of polymer material processing equipment technology, and in particular to a water channel structure for an extruder barrel and an extruder barrel. Background Technology

[0002] During extruder operation, the cooling effect of the barrel is crucial to product quality and equipment performance. Currently common extruder barrel cooling system designs have several shortcomings: While designs with multiple channels in one direction simultaneously providing water inlet and outlet offer large water volume and robustness, suitable for rapid cooling, they result in significant temperature differences between the two ends of the barrel, leading to uneven cooling and affecting product quality stability. While circulating water systems can achieve more uniform barrel temperature, they suffer from small cross-sectional areas in individual pipes, making them prone to clogging and causing cooling system failure. Furthermore, they are unsuitable for applications requiring rapid cooling, as water vaporization can impede flow and temporarily disable the cooling system. These problems limit the efficient and stable operation of extruders and urgently need to be addressed. Utility Model Content

[0003] This application provides a water channel structure for an extruder barrel that achieves uniform cooling, avoids cooling system failure due to water channel blockage, meets the need for rapid cooling, and improves the overall performance of the extruder and product quality.

[0004] One embodiment of this application provides a water channel structure for an extruder barrel, including a water channel disposed inside the barrel. The water channel consists of 22 pipes, with two adjacent pipes merging into a single passage, forming an overall circulating water channel structure. Cooling water enters from one end, circulates five times inside the barrel, and then exits from the other end.

[0005] In the waterway structure provided according to at least one embodiment of the present disclosure, the pipe diameter is 11mm to 12mm.

[0006] Another embodiment of this application provides an extruder barrel, including a barrel body, wherein the barrel body is provided with the water channel structure described in any of the above claims.

[0007] According to at least one embodiment of the present disclosure, the extruder barrel has a pipe diameter of 12 mm.

[0008] According to at least one embodiment of the extruder barrel provided in this disclosure, the cross-sectional area of ​​each single passage of the water channel is 6×6×3.14×2 = 230 square millimeters.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] 1. The circulating water channel structure allows the cooling water to circulate multiple times within the barrel, which can more effectively remove heat from various parts of the barrel. Compared with the design of multiple water channels entering and exiting in one direction at the same time, it greatly reduces the temperature difference between the two ends of the barrel, ensuring uniform barrel temperature and improving the quality stability of extruded products.

[0011] 2. The design of combining two water channels as a pathway improves the water channels' resistance to blockage. Even if one water channel becomes blocked, the other water channel can still flow normally, avoiding the problem of the entire cooling system failing due to the failure of a single water channel and enhancing the reliability of the cooling system.

[0012] 3. The larger single-channel cross-sectional area (230 square millimeters) significantly increases water flow compared to the 5×5×3.14 = 80 square millimeter single-pipe cross-sectional area in a circulating water system. This allows for the passage of large volumes of water when rapid cooling is required, reducing the risk of cooling system failure due to water vaporization, improving cooling efficiency, and making it suitable for rapid cooling applications in extruders.

[0015] This application provides a water channel structure for an extruder barrel that achieves uniform cooling, avoids cooling system failure due to water channel blockage, meets the need for rapid cooling, and improves the overall performance of the extruder and product quality.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] like Figure 1 As shown in the embodiment of this application, the water channel structure for the extruder barrel includes a water channel 20 disposed inside the barrel. The water channel 20 consists of 22 pipes. Two adjacent pipes are merged into one passage, forming a circulating water channel structure. Cooling water enters from one end, circulates five times inside the barrel, and then exits from the other end.

[0018] In some embodiments, the pipe diameter is 11mm to 13mm, preferably 12mm.

[0019] Example 1

[0020] During the manufacturing process of the extruder barrel, 22 water channels with a diameter of 12mm are precisely machined. This ensures the machining accuracy of the water channels and prevents deviations from affecting the cooling effect.

[0021] The two pipes are merged into one channel and installed according to the designed circulating water circuit structure; the cross-sectional area of ​​each single channel is 6×6×3.14×2 = 230 square millimeters. Reliable sealing measures are used at the connection points to prevent cooling water leakage.

[0022] like Figure 2 As shown, during extruder operation, cooling water enters the water channel from the inlet end 21 of the barrel, circulates five times inside the barrel along the designed circulation path, and then exits from the outlet end 22. The flow rate and temperature of the cooling water are controlled and adjusted according to the extruder's operating status to achieve optimal cooling. If any blockage is detected in a water channel during the cooling process, it can be promptly identified using detection equipment. Due to the dual-channel design, the other water channel can still maintain the normal operation of the cooling system. In this case, the blocked water channel can be repaired or cleaned to ensure the continuous and stable operation of the cooling system.
