Description

Technical Field

[0001] This utility model relates to the technical field of cooling in the production of plastic masterbatch, specifically a cooling device for the production of plastic masterbatch. Background Technology

[0002] During the plastic granulation process, the plastic strips extruded from the extruder die need to be cooled before granulation. Currently, the plastic strips are usually cooled by a cooling water tank.

[0003] A search revealed that Chinese utility model patent CN210851265U discloses a cooling water tank for plastic strips used in masterbatch production. The tank includes a main body with two symmetrically arranged connecting holes on its inner sidewall for fixing connecting rods. A plastic strip separation mechanism is provided between the two connecting rods, and a thrust assembly is rotatably connected to each connecting rod. By providing a plastic strip separation mechanism between the two connecting rods, individual plastic strips can be placed in a separation limiting ring groove during use, separating the gaps between each plastic strip and preventing them from easily tangling together in the cooling water tank when the plastic strips are long, thus improving the cooling efficiency. However, the above-mentioned prior art solution results in a large amount of water adhering to the outer wall of the plastic strips after cooling. Plastic strips with a large amount of water adhering to them can easily affect pelletizing when they enter the pelletizer. Therefore, a cooling device for plastic masterbatch production is needed to reduce the impact on pelletizing. Utility Model Content

[0022] 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.

[0023] Example

[0024] Please see Figures 1-4 A cooling device for producing plastic masterbatch includes a cooling water tank 1 and a plastic strip 2, and also includes a conveying mechanism and a drying mechanism, with the drying mechanism installed at the top of the conveying mechanism;

[0025] The conveying mechanism includes a mounting platform 3 and a conveying shaft 4. A mounting plate 5 is provided at the top of the mounting platform 3. The conveying shaft 4 is rotatably connected to the mounting plate 5, and the clinker strip is located on the conveying shaft 4.

[0026] The drying mechanism includes a mounting cover 6, a blower 7, a first connecting pipe 8, a heating box 9, an electric heating wire 10, a second connecting pipe 11, and a first drying cover 12. The bottom end of the mounting cover 6 is connected to the top end of the mounting platform 3, the blower 7 is connected to the top end of the mounting cover 6, the heating box 9 is connected to the top end inside the mounting cover 6, the output end of the blower 7 is connected to the heating box 9, the electric heating wire 10 is installed inside the heating box 9, the top end of the second connecting pipe 11 is connected to the heating box 9, and the bottom end of the second connecting pipe 11 is connected to the first drying cover 12. The first drying cover 12 is located above the plastic strip 2, and a drying port 13 is provided on the side of the first drying cover 12 facing the plastic strip 2. Firstly, the setting of the drying mechanism can dry the plastic strip 2 in a timely manner after it has cooled down. Powering on and starting the blower 7, it delivers air to the heating chamber 9, energizing the motor heating wire 10. After heating by the electric heating wire 10, the air is conveyed through the second connecting pipe 11 to the first drying hood 12. Hot air is blown onto the plastic strip 2 through the drying port 13, quickly removing moisture from the outer wall of the plastic strip 2 and preventing water-laden plastic strip 2 from entering the pelletizer. This ensures the normal operation of the pelletizer and improves pelletizing quality and efficiency. Secondly, the mounting platform 3 and mounting plate 5 in the conveying mechanism provide a stable mounting structure for the conveyor shaft 4, allowing the plastic strip 2 to be smoothly conveyed on the conveyor shaft 4. Combined with the drying mechanism, this enables continuous operation of conveying and drying the cooled plastic strip 2, improving the continuity and efficiency of the production process. Furthermore, this structural design is reasonable, facilitating equipment installation, maintenance, and operation, and possesses high practicality and economy.

[0027] Please see Figures 1-4 The system also includes a third connecting pipe 14 and a second drying hood 15. The input end of the second connecting pipe 11 is connected to the drying chamber, and the output end of the second connecting pipe 11 is connected to the second drying hood 15. The second drying hood 15 is located below the plastic strip 2, and a drying port 13 is provided on the side of the second drying hood 15 facing the plastic strip 2. The third connecting pipe 14 and the second drying hood 15 allow hot air to dry the plastic strip 2 not only from above but also from below. The second connecting pipe 11 introduces heated air into the second drying hood 15, and the plastic strip 2 is dried from the drying port 13 below, achieving double-sided drying of the plastic strip 2. Compared to drying only from above, double-sided drying can more comprehensively and quickly remove moisture from the outer wall of the plastic strip 2, further improving the drying effect and efficiency, ensuring better surface dryness of the plastic strip 2, providing better material conditions for subsequent pelletizing, and reducing pelletizing quality problems caused by residual moisture.

[0028] Please see Figures 1-4An annular limiting groove 16 is provided on the conveyor shaft 4, within which the plastic strip 2 is conveyed. This design ensures the plastic strip 2 is precisely positioned within the groove during conveying. This effectively prevents the plastic strip 2 from shifting or slipping during transport, guaranteeing its stability along the conveying path. Simultaneously, stable conveying helps the drying mechanism to uniformly dry the plastic strip 2, improving drying consistency and reliability. Furthermore, compared to the problem of easy tangling of the plastic strip 2 in existing technologies, the annular limiting groove 16 also prevents the plastic strips 2 from intertwining, further enhancing the orderliness and efficiency of the production process.

[0029] Please see Figures 1-4 Both the first drying hood 12 and the second drying hood 15 are equipped with fixing rods 17, which are connected to the mounting cover 6. The fixing rods 17 on the first drying hood 12 and the second drying hood 15, connected to the mounting cover 6, provide a stable installation method for the drying hoods. This fixing structure ensures that the drying hoods remain stable during operation and will not shake or shift due to the flow of hot air or other external forces. A stable drying hood ensures that hot air is consistently blown out from the drying port 13 and accurately acts on the surface of the plastic strip 2, thereby guaranteeing the stability and reliability of the drying effect. This avoids problems such as uneven drying and incomplete drying in some areas caused by unstable drying hoods, further improving drying quality and the overall performance of the equipment.

[0030] Please see Figures 1-4 A controller 18 is installed on the mounting cover 6, and the controller 18 is electrically connected to the electric heating wire 10. The controller 18 allows for convenient and precise control of the working status of the electric heating wire 10. Operators can flexibly adjust the heating power of the electric heating wire 10 according to actual production needs, thereby controlling the heating temperature of the air inside the heating chamber 9. A suitable heating temperature ensures effective drying of the plastic strips 2 while avoiding excessively high or low temperatures that could negatively impact drying efficiency and energy waste. This intelligent control method improves the operability and adaptability of the equipment, better meeting the drying needs under different production conditions and enhancing the equipment's practicality and production efficiency.

[0031] In summary, when using this cooling equipment for plastic masterbatch production, firstly, the drying mechanism allows for timely drying of the plastic strips 2 after cooling. Powering on and starting the blower 7 delivers air to the heating chamber 9, energizing the motor heating wire 10. After heating by the electric heating wire 10, the air is conveyed through the second connecting pipe 11 to the first drying hood 12. Hot air is blown onto the plastic strips 2 through the drying port 13, quickly removing moisture from the outer wall of the plastic strips 2 and preventing water-laden plastic strips 2 from entering the pelletizer, thus ensuring the normal operation of the pelletizer and improving pelletizing quality and efficiency. Secondly, the mounting platform 3 and mounting plate 5 in the conveying mechanism provide a stable mounting structure for the conveyor shaft 4, allowing the plastic strips 2 to be smoothly conveyed on the conveyor shaft 4. This, combined with the drying mechanism, enables continuous operation of the cooled plastic strips 2 while being conveyed and dried, improving the continuity and efficiency of the production process. Furthermore, this structural design is reasonable, facilitating equipment installation, maintenance, and operation, and possesses high practicality and economy.

[0032] The blower 7, electric heating wire 10, and controller 18 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, so we will not go into detail here. The blower 7, electric heating wire 10, and controller 18 are equipped with matching control switches. The installation position of the control switches is selected according to actual usage requirements to facilitate operation and control by the operator.

[0033] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
