Description

Technical Field

[0001] This utility model relates to the field of plastic particle cooling technology, and in particular to a plastic particle cooling device. Background Technology

[0002] Plastics, as a type of polymer compound, come in many varieties, such as polyethylene and polypropylene, and have a wide range of applications. The molding and processing flow of plastic granules includes batching, mixing, feeding, extrusion, pelletizing, cooling, conveying, vibration separation, and collection.

[0003] Traditional plastic granule cooling devices have some drawbacks. In the plastic granule cooling process, conventional duct cooling methods require the material to be kept in a stacked state, which can easily lead to a central accumulation effect. Under the action of gravity, the granules gather towards the central area, resulting in uneven airflow distribution. The central area has high density, which affects the heat exchange efficiency, while the edge area suffers from insufficient heat dissipation due to airflow short circuits. This uneven heat dissipation directly affects key indicators such as the crystallinity and moisture content of the material. Utility Model Content

A crossbar 2 is fixedly connected to the inner wall of the support 1. An installation groove 3 is opened at the upper end of the crossbar 2. The cooling auxiliary mechanism 7 includes a cooling chamber 71 fixedly connected to the inner side of the support 1. A vent hole 72 is opened at one end of the cooling chamber 71. A support frame 73 is fixedly connected to the upper end of the support 1. A rotating shaft 74 is movably connected to the inner side of the support frame 73. A transmission device 75 is installed at one end of the rotating shaft 74. A motor 76 is installed at one end of the transmission device 75 near the lower side of the rotating shaft 74. An adjuster 77 is movably connected to the inner side of the transmission device 75. A tipping rod 78 is movably connected to the inner side of the cooling chamber 71. A bolt 79 is threadedly connected to the inside of the adjuster 77.

[0022] In this embodiment, the upper end of the cooling chamber 71 is movably connected to the upper cover plate 710 via a rotating shaft damping, and the lower end of the cooling chamber 71 is movably connected to the lower cover plate 711 via a rotating shaft damping. Locking buckles are installed at both the upper and lower ends of the cooling chamber 71. The rotating shaft 74 passes through the interior of the cooling chamber 71 and is movably connected to the cooling chamber 71. The front end of the tipping rod 78 is fixedly connected to the rear end of the rotating shaft 74. The transmission device 75 includes two sets of slots and a set of belts. The lower end of the motor 76 is fixedly connected to the inner bottom of the bracket 1. The adjuster 77 is placed at the upper end of the crossbar 2. The bolt 79 extends into the inner side of the mounting groove 3 and is threadedly connected to the mounting groove 3. The upper cover plate 710 is in contact with the locking buckle, and the lower cover plate 711 is in contact with another set of locking buckles.

[0023] Specifically, the top cover 710 is opened, plastic granules are poured into the cooling chamber 71, and then the top cover 710 is closed. The rotation of the top cover 710 is limited by the locking buckle. Then the motor 76 is started, which drives the rotating shaft 74 to rotate via the transmission 75. The rotating shaft 74 drives the tipping rod 78 to rotate within the cooling chamber 71, thereby causing the tipping rod 78 to flip over the plastic granules piled up in the cooling chamber 71, allowing the plastic granules to be cooled evenly by airflow. By starting the motor 76, which drives the rotating shaft 74 via the transmission 75, and causing the rotating shaft 74 to drive the tipping rod 78 to rotate within the cooling chamber 71, the purpose of making it easier for the tipping rod 78 to flip over the plastic granules piled up in the cooling chamber 71 can be achieved, thereby allowing the plastic granules to be cooled evenly by airflow.

[0024] In this embodiment, the fan 4 is placed at one end of the support 1. The upper end of the fan 4 is fixedly connected to the connecting chamber 5. The upper end of the connecting chamber 5 is equipped with the air duct 6. One end of the air duct 6 is equipped with the connecting pipe 8. One end of the connecting pipe 8 is fixedly connected to one end of the cooling chamber 71. The connecting pipe 8 and the cooling chamber 71 are interconnected. The inner side of the support 1 near the lower side of the cooling chamber 71 is fixedly connected to the unloading rack 9.

[0025] Specifically, the blower 4 is started, blowing air into the connecting chamber 5, and the air in the connecting chamber 5 flows into the air duct 6, and then the air flows through the connecting pipe 8 into the cooling chamber 71, thus cooling the plastic granules in the cooling chamber 71. Then the locking buckle is opened and the lower cover 711 is opened, so that the cooled plastic granules fall onto the unloading rack 9, making it easier for workers to collect the cooled plastic granules.

[0026] Working principle:

[0027] In use, first close the lower cover 711, then use the locking buckle to limit the rotation of the lower cover 711, and then open the upper cover 710 to pour the plastic granules into the cooling chamber 71. Then close the upper cover 710 again, and use the locking buckle to limit the rotation of the upper cover 710. Then start the fan 4 to blow air into the connecting chamber 5, and let the air in the connecting chamber 5 flow into the air duct 6, and then let the air flow into the cooling chamber 71 through the connecting pipe 8, so as to cool the plastic granules in the cooling chamber 71. Then start the motor 76, so that the motor 76 drives the rotating shaft 74 to rotate through the transmission 75, and the rotating shaft 74 drives the tilting mechanism. The material rod 78 rotates inside the cooling chamber 71, causing the tipping rod 78 to flip over the plastic granules piled up inside the cooling chamber 71, allowing the plastic granules to be cooled evenly by airflow. Then, the locking buckle is opened, and the lower cover plate 711 is opened, allowing the cooled plastic granules to fall onto the unloading rack 9, making it easier for workers to collect the cooled plastic granules. By starting the motor 76, the motor 76 drives the rotating shaft 74 to rotate through the transmission 75, and the rotating shaft 74 drives the tipping rod 78 to rotate inside the cooling chamber 71, which can facilitate the tipping rod 78 to flip over the plastic granules piled up inside the cooling chamber 71, thereby allowing the plastic granules to be cooled evenly by airflow.
