It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastic granulator refers to a device that uses high-temperature melting, plasticizing, and extrusion processes to change the physical properties of plastics according to different uses, to achieve plasticization and molding of plastics, and to make plastic raw materials into granular products suitable for secondary processing. After the plastic granules are processed, special cooling devices are required for rapid cooling.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 In this embodiment, a plastic granulator with a cooling device includes a granulator shell 1, a feed port 2 is provided at the top of the granulator shell 1, a conveying pipe 3 is fixedly connected to one side of the feed port 2, and a cooling box 4 is connected to the end of the conveying pipe 3 away from the granulator shell 1. A cooling mechanism 5 is provided in the cooling box 4. Plastic is added to the granulator shell 1 through the feed port 2, and the plastic is granulated in the granulator shell 1. After the plastic is added to the granulator shell 1, the plastic is softened by heating and then extruded by a spiral device. The softened extruded plastic is formed after passing through a mold. The formed plastic is cut into granules and discharged from the granulator shell 1 to the cooling box 4 through the conveying pipe 3. The formed plastic is cooled in the cooling box 4 and discharged through the discharge pipe after cooling.

[0025] Specifically, the cooling mechanism 5 includes a water pump 501, a water pump 501 is installed on the top of the cooling box 4, a water pipe 502 is connected between the cooling box 4 and the water pump 501, a water supply pipe 503 is connected to the water outlet of the water pump 501, a branch pipe 504 is connected to the bottom of the water supply pipe 503, a spray head 505 is connected to the bottom of the branch pipe 504, a motor 506 is fixedly installed on the side wall of the cooling box 4, a rotating rod 507 is fixedly installed on the output shaft of the motor 506, a connecting rod 508 is fixedly installed on the outside of the rotating rod 507, and a container frame 509 is fixedly installed on the outside of the connecting rod 508. After entering the cooling box 4 from the granulator housing 1, the cooling water contained in the cooling box 4 will cool the plastic particles. At this time, in order to prevent the accumulation of plastic particles, the motor 506 can be controlled to drive the holding frame 509 to rotate. The holding frame 509 continuously holds the plastic particles in the cooling water. At the same time, the spray head 505 on the top sprays and cools the plastic particles in the holding frame 509. After cooling, the plastic particles re-enter the cooling water, thereby reducing the accumulation of plastic particles in the cooling water, so as to achieve uniform cooling. At the same time, the spraying water is the cooling water pumped out by the water pump 501, which is recycled.

[0026] Specifically, a plurality of water leakage holes are evenly arranged on the holding frame 509, and the number of the holding frame 509 is more than five. By setting a plurality of water leakage holes, the heated water can be leaked, so that the plastic particles in the holding frame 509 are continuously sprayed and cooled by the coolant with a lower temperature, and the cooling effect is good.

[0027] Specifically, a water inlet pipe 6 is installed on the side wall of the cooling box 4, and a water outlet pipe 7 is installed on the side wall of the cooling box 4. The water inlet pipe 6 is provided to continuously add new cooling water to reduce the temperature inside the cooling box 4, and the water outlet pipe 7 is used to discharge the cooling water.

[0028] Specifically, a temperature sensor 8 is installed inside the cooling box 4, and a controller is provided outside the granulator housing 1. The temperature sensor 8 is electrically connected to the controller. The temperature sensor 8 is used to detect the temperature of the coolant and send the detected data to the controller. The temperature of the coolant can be understood through the display screen on the controller, which facilitates the replacement of the coolant.

[0029] To sum up, the plastic granulator with a cooling device is provided with a cooling mechanism 5. When the plastic enters the cooling box 4 from the granulator housing 1, the cooling water contained in the cooling box 4 will cool the plastic particles. At this time, in order to prevent the accumulation of plastic particles, the motor 506 can be controlled to drive the holding frame 509 to rotate. The holding frame 509 continuously holds the plastic particles in the cooling water. At the same time, the spray head 505 on the top sprays and cools the plastic particles in the holding frame 509. After cooling, the plastic particles re-enter the cooling water, thereby reducing the accumulation of plastic particles in the cooling water, so as to achieve uniform cooling. At the same time, the water used for spraying is the cooling water pumped out by the water pump 501, which is recycled and solves the problem that the accumulation of plastic makes it inconvenient to cool the plastic evenly.
