[0028] The circulating cooling mechanism comprises a water tank 6 arranged at a bottom of the cooling cylinder 2, a water inlet pipe 7 fixedly communicated with one side of the cooling cylinder 2, one end of the water inlet pipe 7 fixedly communicated with one side of the water tank 6 through a water pump, a water outlet pipe 8 fixedly communicated with a top of the cooling cylinder 2, one end of the water outlet pipe 8 fixedly communicated with a distribution tank 9, a water return pipe 10 fixedly communicated with a bottom of the distribution tank 9, one end of the water return pipe 10 fixedly communicated with one side of the water tank 6, a cooling mechanism arranged on one side of the water tank 6, and an exhaust mechanism arranged on a top of the water tank 6.

[0029] In the embodiment, the color master batch is generally melted and extruded by the extruder 1, and then pelletized. However, the existing pelletizing device does not have the function of cooling the extruded raw material when pelletizing, and the raw material still has heat that cannot be solidified, which affects the pelletizing effect. Therefore, by arranging the circulating cooling mechanism, the water in the water tank 6 can be pumped into the inside of the cooling cylinder 2 through the water inlet pipe 7, and when the raw material is extruded from the extruder 1, it can be directly cooled underwater, thereby being quickly solidified. At the same time, the motor 4 is started to drive the pelletizing cutter 5 to rotate, so as to achieve the effect of underwater pelletizing. The motor 4 continuously supplies water into the cooling cylinder 2, and when the cooling cylinder 2 is full of water, the pelletized color master batch is driven by the water flow and falls into the distribution tank 9 through the water outlet pipe 8. The color master batch is retained on the screen 29, and the water flow reenters the water tank 6 through the water return pipe 10. By the underwater pelletizing mode, the pelletizing effect is effectively improved.

[0030] The problem that the existing pelletizing device does not have the function of cooling the extruded raw material when pelletizing, and the raw material still has heat that cannot be solidified, which affects the pelletizing effect is solved.

[0031] The inner wall of the distribution tank 9 is fixedly connected with a screen 29, and one side of the distribution tank 9 is fixedly communicated with a discharge pipe 30 through an electromagnetic valve.

[0032] In the embodiment, by arranging the screen 29 and the discharge pipe 30, the color master batch can be screened out when the water flow and the color master batch pass through the distribution tank 9, and the color master batch can be discharged from the discharge pipe 30 by opening the electromagnetic valve.

[0033] Preferably, a second one-way valve is fixedly installed on the surface of the water inlet pipe 7.

[0034] In this embodiment, by setting the second one-way valve, which is a valve that can only enter water into the cooling cylinder 2, the backflow of the raw material after cutting can be avoided. Embodiment 2

[0035] Please refer to Figure 2 , Figure 5 and Figure 6 On the basis of embodiment one, this embodiment takes into account that the water temperature will also rise when the extruded raw material is cooled by circulating water, and thus the raw material cannot be quickly cooled, affecting the cutting effect. The cooling mechanism in this application includes a refrigeration box 11 fixedly connected to one side of the water tank 6, a refrigeration fin 12 is installed inside the refrigeration box 11, two conduction rods 13 are fixedly connected to one side of the refrigeration fin 12, a mounting bracket 14 is fixedly connected to the top of the water tank 6, a motor 15 is fixedly installed on the top of the mounting bracket 14, the output end of the motor 15 penetrates into the inside of the water tank 6 and is fixedly connected with a rotating rod 16, and two stirring leaves 17 are fixedly connected to the surface of the rotating rod 16.

[0036] In this embodiment, it is considered that the water temperature will also rise when the extruded raw material is cooled by circulating water, and thus the raw material cannot be quickly cooled, affecting the cutting effect. Therefore, by setting the cooling mechanism, the temperature of the conduction rod 13 can be reduced by starting the refrigeration fin 12, and the cold of the conduction rod 13 can be transmitted to the inside of the water tank 6 to cool the water in the water tank 6. At the same time, the motor 15 is started to drive the rotating and stirring leaves 17 to rotate, so that the hot water flowing back is quickly mixed with the cold water in the water tank 6, and then the water is circulated into the cooling cylinder 2 to cool the raw material, further improving the cutting effect.

[0037] The problem that the water temperature will also rise when the extruded raw material is cooled by circulating water, and thus the raw material cannot be quickly cooled, affecting the cutting effect, is solved.

[0038] The material of the conduction rod 13 is copper, and one end penetrates into the inside of the water tank 6.

[0039] In this embodiment, by setting the material of the conduction rod 13 as copper, the cold generated by the refrigeration fin 12 can be transmitted to the water in the water tank 6 for rapid cooling. Embodiment 3

[0041] In the embodiment, the exhaust mechanism is arranged, so that the cam 26 is driven to rotate while the motor 15 rotates, when the protruding end of the cam 26 contacts with the pressing plate, the pressing plate, the pushing rod 24, the pushing block 23 and the piston 22 are pushed to move, and the gas in the gas collecting box 18 is compressed. When the gas collecting in the gas collecting box 18 reaches the limit of the one-way pressure valve, the compressed gas enters the water tank 6 through the transmission pipe 20, and the hot gas in the water tank 6 is quickly discharged through the exhaust pipe 21, so as to further cool the water.

[0042] It should be noted that the first one-way valve is a valve that can only inlet air into the gas collecting box 18, and the one-way pressure valve is a valve that can only inlet air into the transmission pipe 20.

At the same time, the motor 4 is started to drive the cutting knife 5 to rotate, so as to achieve the effect of underwater cutting. The motor 4 continuously supplies water to the inside of the cooling cylinder 2, when the cooling cylinder 2 is full of water, the cut color master batch is also dropped into the distribution box 9 under the driving of the water flow through the drain pipe 8, the color master batch is stopped on the screen 29, and the water flow enters the water tank 6 again through the backwater pipe 10. The underwater cutting effectively improves the cutting effect.

[0046] At the same time, the temperature of the conducting rod 13 is lowered by starting the refrigeration sheet 12, and the conducting rod 13 transmits cold to the inside of the water tank 6, and the water in the water tank 6 is cooled. At the same time, the motor 15 is started, and the rotating and stirring blades 17 are rotated, so that the hot water flowing back is quickly mixed with the cold water in the water tank 6, and then the raw material is cooled in the cooling cylinder 2, and the effect of cutting is further improved.

[0047] At the same time of the rotation of the motor 15, the cam 26 is rotated, and when the convex end of the cam 26 contacts the pressing plate, the pressing plate, the pushing rod 24, the pushing block 23 and the piston 22 are pushed to move, and the gas in the gas collecting box 18 is compressed. When the gas collecting in the gas collecting box 18 reaches the limit of the one-way pressure valve, the compressed gas enters the inside of the water tank 6 through the transmission pipe 20, and the hot gas in the water tank 6 is quickly discharged through the exhaust pipe 21, and the water is further cooled.

[0048] It should be noted that the motor 4, the water pump, the refrigeration sheet 12, the motor 15 and the electromagnetic valve are devices or equipment existing in the prior art or devices or equipment that can be realized in the prior art, and the power supply of the motor 4, the water pump, the refrigeration sheet 12, the motor 15 and the electromagnetic valve and its principle are clear to those skilled in the art, and will not be described in detail.
