[0002] In the prior art, when producing plastic pellets, the plastic strips continuously extruded by the plastic extruder are generally immersed in the water of a water tank, the water in the water tank cools the plastic strips, and then the cooled plastic strips are cut into plastic pellets by a plastic pelletizer.

[0003] However, sometimes, based on actual production needs, such as: in order to shorten the production line, or to reduce the plastic pelletizer to reduce equipment costs. A cutter will be installed on the outside of the extruder head of the plastic extruder, and then the cutter will rotate on the outside of the extruder head, so that the extruded plastic can be directly cut into pellets on the outside of the extruder head. Depending on the different properties of the extruded plastic, it is sometimes necessary to preliminarily cool the extruded plastic at the extruder head to avoid sticking to the cutter. However, the existing immersion tank cannot preliminarily cool the extruded plastic directly at the extruder head. Summary of the invention

[0004] The utility model aims to provide a plastic particle cooling device, which can directly perform preliminary cooling on the extruded plastic at the extrusion head of a plastic extruder, so that a cutter can directly cut the extruded plastic into particles outside the extrusion head.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The plastic particle cooling device comprises: a spray head for spraying water mist toward an extrusion head of a plastic extruder, a water tank located below the spray head for receiving water flow and plastic particles, a conveying network chain for conveying plastic particles from inside the water tank to outside the water tank, and a heat dissipation fan for blowing air toward a downstream section of the conveying network chain; wherein the spray head is connected to a water source through a hose and is equipped with an adaptor valve; the upstream section of the conveying network chain is located below the liquid level of the water tank, and the downstream section is located above the liquid level of the water tank; the water tank is connected to a water pump, and a filter is provided at the connection point.

[0009] Optionally, the first locking nut is provided with an extended handle.

[0010] Optionally, the rotating frame includes: a main frame, and a clamping member cooperating with the main frame to clamp the spray head; the main frame and the clamping member are connected by bolts; and the shaft is arranged on the main frame.

[0011] Optionally, the first slide is installed on the second slide; the first slide is provided with a first mounting hole, the second slide is provided with a second mounting hole corresponding to the first mounting hole, and adapted with bolts; the first mounting hole or the second mounting hole is arranged as a strip hole extending in the left-right direction.

[0012] Optionally, the sink is provided with a vertical frame extending upward, and the second slide is installed on the vertical frame; the second slide is also provided with a third mounting hole, and the vertical frame is provided with a fourth mounting hole corresponding to the third mounting hole and adapted with bolts; the third mounting hole or the fourth mounting hole is arranged as a strip hole extending in the up and down directions.

[0015] The working principle of the utility model is as follows: the spray head sprays water mist toward the extrusion head of the plastic extruder, and the extruded plastic can be preliminarily cooled at the extrusion head. The water mist sprayed onto the extrusion head will eventually drip downwards and fall into the water tank together with the cut plastic particles. The plastic particles will be cooled in the water tank for two stages and then transported to the outside of the water tank through the conveying net chain. The heat dissipation fan will blow air to the downstream section of the conveying net chain to perform three-stage cooling and preliminarily dry the plastic particles: on the one hand, the water droplets on the surface of the plastic particles can be blown into the water tank; on the other hand, the heat of the plastic particles can be taken away by the airflow, and at the same time, the water on the surface of the plastic particles can be accelerated to evaporate to further take away the heat of the plastic particles. The water in the water tank can be pumped out through the pumping pipe to avoid overflow.

[0016] It can be seen that the beneficial effect of the utility model is that the extruded plastic can be preliminarily cooled directly at the extrusion head of the plastic extruder, so that the cutter can directly cut the extruded plastic into particles outside the extrusion head. In addition, the plastic particles can be preliminarily dried while being cooled by the heat dissipation fan, so that the residual water on the surface of the plastic particles is reduced, so that the downstream deep drying of the plastic particles is more convenient and quick.
