Description

Technical Field

[0001] This utility model belongs to the field of plastic fiber preparation technology, specifically a cooling and molding box for plastic fiber preparation. Background Technology

[0002] A cooling molding box for plastic fiber preparation is a device used to cool and mold plastic fibers. The outer shell of the cooling molding box is generally made of metal, and a chiller is commonly used as the cooling source. It can provide stable low-temperature cooling water, and the water temperature can be adjusted according to the cooling requirements of the plastic fibers, generally between 5-15℃. By controlling the cooling water temperature, the cooling rate of the plastic fibers can be precisely controlled, thus affecting its molding quality. Before entering the cooling molding box, the plastic fibers are usually in a high-temperature molten state. When they enter the molding die inside the box through the conveying system, the cooling system begins to function. Cold water circulates in the cooling pipes, carrying away heat from the die and the plastic fibers. The heat from the plastic fibers is conducted to the die through contact with the die, and the die then transfers the heat to the cooling water in the cooling pipes. As heat is continuously dissipated, the temperature of the plastic fibers gradually decreases, changing from a molten state to a solid state, thus completing the cooling molding process. However, the following defects still exist:

[0003] In the process of plastic fiber preparation, the heat dissipation inside the molding cavity is only achieved through water cooling, which is a single heat dissipation method. Utility Model Content

[0025] Depend on Figure 1-6 The present invention relates to a cooling molding box for preparing plastic fibers, comprising a cooling molding box 1, a feed pipe 2 installed on one side of the cooling molding box 1, a discharge pipe 3 installed on the other side of the cooling molding box 1, a molding cavity 4 opened inside the cooling molding box 1, the two ends of the molding cavity 4 being connected to the feed pipe 2 and the discharge pipe 3 respectively, a top air cooling component 5 installed at the top of the cooling molding box 1, and a water cooling circulation component 6 provided inside the cooling molding box 1.

[0026] The top air-cooled assembly 5 includes a cooling box 501 fixedly installed on the top of the cooling molding box 1. Heat-conducting plates 502 are equidistantly installed on the top of the cooling molding box 1. The heat-conducting plates 502 are located inside the cooling box 501 and are used to transfer heat from the molding cavity 4 to the cooling box 501. Three fan boxes 503 are equidistantly installed on the top of the cooling box 501. Cooling fans 504 are installed inside the fan boxes 503. Exhaust holes 505 are evenly opened on one side of the cooling box 501.

[0027] The water-cooled circulation assembly 6 includes two symmetrically arranged connecting grooves 601 inside the cooling and forming chamber 1. A diversion groove 603 is formed at the bottom end of each connecting groove 601. Cooling channels 604 are equidistantly arranged between the two diversion grooves 603 and are located on the outside of the forming cavity 4. Connecting pipes 602 are symmetrically installed on both sides of the cooling and forming chamber 1. Each connecting pipe 602 is connected to one of the two diversion grooves 603. A cooling water tank is located between the two connecting pipes 602, and each connecting pipe 602 is connected to one of the two ports of the cooling water tank. A connecting slot 601 is respectively disposed below two fan boxes 503 located on both sides above the cooling box 501. A top slot 605 is formed at the top of the connecting slot 601, extending into the interior of the cooling box 501. A rotating piston rod 606 is rotatably mounted inside the top slot 605, with its outer wall tightly against the inner wall of the top slot 605. The top of the rotating piston rod 606 is fixedly connected to the output shaft of the cooling fan 504, and a rotating sleeve 607 is fixedly mounted at the bottom of the rotating piston rod 606. The fan box 503... An internal cooling fan 504 is installed, which provides air cooling when turned on. Two connecting slots 601 inside the cooling molding box 1 are located below the cooling fans 504 on both sides. A rotating piston rod 606 is installed between the output shaft of the cooling fan 504 and the rotating sleeve 607, allowing the cooling fan 504 to drive water cooling and air cooling simultaneously, improving the cooling effect. The rotating sleeve 607 is positioned between the connecting pipe 602 and the diversion slot 603, with its outer wall in close contact with the inner wall of the connecting slot 601. Fan blades 608 are installed at equal angles on the inner wall of the rotating sleeve 607. A cooling box 501 is set at the top of the cooling molding box 1. The heat conduction plate 502 can conduct heat inside the molding cavity 4. The cooling fan 504 drives the air to flow continuously through the heat conduction plate 502, which facilitates the cooling of the inside of the molding cavity 4. At the same time, the cooling channels 604 are equally spaced on the outside of the molding cavity 4. When the rotating sleeve 607 rotates, the fan blades 608 rotate, which drives the cooling water to flow continuously through the cooling channels 604, further realizing the cooling and achieving dual cooling of air cooling and water cooling.

[0028] Working principle: When working, the feed pipe 2 is first connected to the plastic fiber extrusion equipment. During use, the plastic fiber is continuously extruded from the feed pipe 2 into the molding cavity 4. Inside the molding cavity 4, the plastic fiber is cooled and shaped. Finally, the solidified plastic fiber is extruded from the discharge pipe 3.

[0029] During cooling, the heat-conducting plate 502 transfers the heat inside the molding cavity 4 to the cooling box 501. The cooling fans 504 are turned on, which drives the outside air from the fan box 503 into the cooling box 501 and then exhausts it from the exhaust port 505. During the air circulation, the heat on the surface of the heat-conducting plate 502 is carried away, thereby cooling the plastic fibers inside the molding cavity 4.

[0030] Since a cooling water tank is connected between the two connecting pipes 602, after adding cooling water to the cooling water tank, the cooling water enters the distribution groove 603 and the cooling channel 604. When the cooling fan 504 is turned on, it drives the rotating piston rod 606 to rotate, which in turn drives the rotating sleeve 607 to rotate. The rotating sleeve 607 is located inside the connecting groove 601, and the inner wall of the rotating sleeve 607 is equipped with fan blades 608 at equal angles, thereby driving the cooling water to circulate continuously, so that the cooling water cools the molding cavity 4, thereby improving the cooling molding effect.
