Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to the water cooling tank of a strip-drawing water-cooled pelletizing production line. Background Technology

[0002] In a plastic extrusion and water-cooled pelletizing production line, the water-cooling tank is a crucial component for the initial shaping and cooling of molten material. Its function is to rapidly cool the extruded plastic strips after they have passed through the die, bringing their temperature down to a suitable range for pelletizing, thus ensuring the molding quality and dimensional stability of the plastic pellets. With increasingly stringent requirements for plastic pellet quality control, the uniformity, cooling efficiency, and temperature control accuracy of the water-cooling process have become critical factors affecting the stable operation of the entire production line.

[0003] Currently, common water-cooled tank structures mainly consist of a long tank body, a water tank, inlet and outlet ports, and supporting components. Cooling water flows into the tank body through the inlet pipe, passes through the entire cooling channel, and exits through the outlet. During the cooling process, the plastic strips are arranged in a straight line within the tank, surrounded and cooled by the cooling medium. Some devices, to enhance the cooling effect, also add an insulation layer to the outside of the tank body or employ a constant-temperature circulation device to maintain the overall water temperature. The overall structural design emphasizes the continuity of the water flow path and the reduction of flow resistance to ensure stable operation of the plastic strips during the cooling process and a certain degree of temperature control.

[0004] However, existing water-cooled tank devices generally lack sophisticated independent flow control structures, leading to uneven distribution of cooling water and coarse temperature regulation during the flow of cooling water within the tank. Especially in applications involving long distances or simultaneous cooling of multiple plastic strips, localized areas may experience poor cooling due to low water flow velocity or heat accumulation, thus affecting the pelletizing consistency and product quality stability of the entire production line. The difficulty in differentiated control at different locations also limits the application of this type of equipment in high-precision plastic particle production processes. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water cooling tank for a strip-drawing water-cooled pelletizing production line, which aims to improve the existing structure's lack of an independent flow control structure, resulting in coarse temperature regulation of the cooling medium, local cooling imbalance, and difficulty in achieving precise temperature control.

[0009] Through the above technical solution, the motor drives the fixed disk to move the baffle back and forth. The baffle breaks the laminar flow of water, promotes the formation of turbulent flow, and improves the heat exchange efficiency. The sliding block and the limiting plate work together to control the movement range of the baffle and ensure stable and reliable movement.

This effectively avoids the problem of insufficient or uneven local cooling caused by water flow short circuits in traditional structures. At the same time, controllable adjustment components are set outside each water inlet pipe. Through an electric push rod driving a rack and pinion to drive a gear-linked sliding plate, the opening of the valve plate is dynamically adjusted, realizing independent control of the cooling water flow in each zone. This meets the differentiated cooling intensity requirements of different plastic melting bars or production processes, and improves the accuracy of temperature control and the adaptability of the cooling device.

[0023] 2. In this invention, by setting a reciprocating baffle inside the water-cooling tank, setting heat dissipation fins on the outside, and coating the inner wall with thermally conductive silicone grease, the three elements work synergistically to effectively enhance the overall heat transfer performance of the cooling structure. The reciprocating disturbance of the baffle breaks the laminar flow of the water, forming turbulent flow, which improves the heat exchange efficiency between the water and the molten strip. The heat dissipation fins expand the outer surface area of ​​the water-cooling tank, enhancing its heat dissipation capacity with the environment. The thermally conductive silicone grease fills the thermal interface between the tank and the water, improving the overall thermal conductivity, thereby shortening the cooling response time, improving cooling uniformity, and meeting the needs of high-speed or high-precision cooling conditions.

[0024] 3. In this utility model, a cooling circuit consisting of a water pump, a water tank, and a control box is also provided. Combined with temperature sensors and frequency conversion control technology, a closed-loop adjustable intelligent cooling device is constructed. The device automatically adjusts the speed and flow rate of the water pump by collecting the cooling water temperature signal in real time, ensuring constant temperature and rapid response during the cooling process. This effectively solves the problems of large temperature fluctuations, slow adjustment, and low energy efficiency of traditional water cooling devices. At the same time, the bottom column and support structure ensure good overall equipment stability, facilitates installation and maintenance, and is suitable for various industrial plastic melting bar cooling scenarios.

[0034] Working principle: When the water cooling tank of the strip-making and pelletizing production line is needed, multiple partition plates 9 are first fixedly connected to the inner wall of the water cooling tank body 3, which can divide the internal space of the tank into multiple independent cooling zones. The cooling zones exchange limited water flow through the holes on the partition plates 9, so that the cooling water flows in an orderly and slow transition state in the tank, avoiding the short flow phenomenon caused by a single water flow channel. This helps to control the water flow path and flow rate in each area, thereby improving the stability and uniformity of cooling. At the same time, the water inlet pipe 16 fixedly connected to the outer wall of the water cooling tank body 3, together with the adjustment component, can further realize the precise control of the flow rate. The electric push rod 11 drives the rack 23 to move, and the rack 23 drives two gears 22 to rotate simultaneously, respectively driving the sliding plate 20 to slide along the sliding rod 21, thereby adjusting the opening of the internal pipe 10 of the valve plate 18, realizing the dynamic control of the flow rate of the water inlet pipe 16. Through these structures, the cooling water flow rate of each zone can be adjusted separately according to the cooling intensity requirements of different plastic strips, realizing differentiated temperature control and significantly improving the adaptability and accuracy of cooling. Furthermore, to further improve cooling efficiency and heat exchange response speed, a turbulence structure is set inside the water-cooled tank body 3, and multiple heat dissipation fins 5 are set on the outside and coated with thermally conductive silicone grease on the inner wall. The three work together to significantly improve the heat transfer efficiency of the entire cooling structure. The motor 6 drives the fixed disk 25 to rotate through the rotating shaft 29. The outer wall of the fixed disk 25 is connected to the second fixed block 30. One end of the second fixed block 30 is connected to another fixed disk 25. The outer wall of the second fixed block 30 is slidably connected to the inner wall of the sliding block 28. One end of the sliding block 28 is inserted into the limiting plate 31 and fixedly connected to the inner wall of the turbulence plate 27. This allows the fixed block 30 to slide on the inner wall of the sliding block 28 when the motor 6 rotates. During the rotation, the second fixed block 30 is slidably moved through the limiting hole on the inner wall of the limiting plate 31. With the limit setting, the baffle 27 can slide back and forth under the guidance of the arc plate 26. When the baffle 27 moves in the water, it breaks the original water flow state and forms water flow turbulence, thereby accelerating the heat exchange process between the water and the plastic strip, improving cooling uniformity, shortening the cooling response time, and adapting to the cooling speed requirements of different production rhythms. At the same time, the outer wall of the water cooling tank body 3 is provided with multiple heat dissipation fins 5. By increasing the surface area in contact with air, the heat exchange efficiency between the water cooling tank and the external environment is improved, effectively promoting the release of heat from the inside of the tank to the outside. In order to further reduce the thermal resistance between the cooling water and the tank, a layer of thermally conductive silicone grease is coated on the inner wall surface of the water cooling tank body 3. This silicone grease layer can improve the thermal conductivity between the tank material and the coolant. Finally, a water pump 12 is installed outside the water-cooled tank body 3, and a water tank 13 is connected to its input end. By forming a closed cooling loop, the cold water is circulated. To improve the energy efficiency and adaptability of the cooling device, frequency conversion control technology is used to adjust the speed of the water pump 12. The cold water flow rate can be automatically adjusted according to the actual cooling load to reduce energy consumption while ensuring the cooling requirements of the melting bar. At the same time, a temperature sensor 17 is installed on the outer wall of the pipe 10 to collect water temperature data of different cooling areas in real time. After the temperature signal is transmitted to the control box 14, the internal control device automatically adjusts the working state of the water pump 12 to ensure that the cooling water flow and temperature are always kept within the set range. This realizes dynamic monitoring and closed-loop regulation of the cooling device, improves the temperature control accuracy and response speed, and significantly reduces energy consumption, effectively solving the problem of large temperature fluctuations in traditional cooling devices.
