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 1-4 The utility model provides an embodiment: a plastic pellet extruder with a cooling effect, comprising a cooling trough 1, two sets of support frames 2 are fixedly installed on the left and right edges of the cooling trough 1, a first guide wheel 3 is rotatably connected to the support frame 2, a linkage component 4 is provided in the cooling trough 1, and a drying component 5 is provided on the right side of the cooling trough 1;

[0025] The linkage assembly 4 includes a fixed rod 41, a roller 42, a rotating blade 43, a water inlet pipe 44 and a water outlet pipe 45. Four sets of fixed rods 41 are provided inside the cooling trough 1. The surface of the fixed rod 41 is provided with a roller 42. Two sets of rotating blades 43 are provided on both sides of the roller 42. The right side of the cooling trough 1 is provided with a water inlet pipe 44, and the left side of the cooling trough 1 is provided with a water outlet pipe 45.

[0026] By arranging the linkage component 4 and the drying component 5, the present device solves the problem that using static liquid water for cooling is not conducive to rapid heat dissipation, may also increase the possibility of loss of water-soluble substances, and has a poor cooling effect.

[0027] Furthermore, the drying assembly 5 includes a drying box 51, a partition 52, a second guide wheel 53 and a fan 54. The drying box 51 is fixedly connected to the right side of the cooling tank 1. The partition 52 is installed in the drying box 51. The upper surface of the partition 52 is fixedly connected to two sets of second guide wheels 53. Four sets of fans 54 are fixedly installed on both sides of the top of the drying box 51. Figure 3 As shown, this structure is used to allow the monofilament to pass through the drying box 51 and the surfaces of the two sets of second guide wheels 53, and the liquid on the surface of the monofilament is dried by the four sets of fans 54 on the top.

[0028] Furthermore, both ends of the fixing rod 41 are fixedly connected to the inner wall of the cooling tank 1, the roller 42 is rotatably connected to the fixing rod 41, the inner sides of the two sets of rotating blades 43 are fixedly connected to the outer surface of the roller 42, and the water inlet pipe 44 and the water outlet pipe 45 are connected to the interior of the cooling tank 1. Figure 2 As shown, the structure is used to pass the monofilament through the surface of four groups of rollers 42 in sequence. When the monofilament moves, the rollers 42 and the rotating blades 43 are driven to rotate on the surface of the fixed rod 41. When the rotating blades 43 rotate, the liquid in the cooling tank 1 flows, thereby taking away the heat of the monofilament and improving the cooling effect. The liquid inside the cooling tank 1 can be circulated and replaced through the water inlet pipe 44 and the water outlet pipe 45 respectively provided on both sides of the cooling tank 1.

[0029] Furthermore, the bottom of the drying box 51 is movably connected to the collecting box 6 on the lower side of the partition 52. The surface of the partition 52 is provided with holes at equal intervals. The diameter of the partition 52 is adapted to the inner diameter of the collecting box 6. Figure 3 As shown, this structure is used to dry the monofilament through the fan 54, so that the liquid on the surface falls on the surface of the partition 52 and flows into the collection box 6 through the holes in the partition 52. The liquid is collected for easy recycling and avoids waste.

[0030] Furthermore, the surface of the first guide wheel 3 is fixedly connected to the limit plate 8 at equal intervals, and the interior of the first guide wheel 3 is fixedly installed with a temperature sensor 7. Figure 4 As shown, the structure is used to separate the monofilaments on the surface of the first guide wheel 3 through the limiting plate 8, and to detect the monofilaments passing through the cooling tank 1 through the temperature sensor 7 to prevent the monofilament temperature from being out of the specified range.

[0031] Furthermore, the fixing rods 41 are staggered and installed with each other, and a baffle is installed at the center of the roller 42. Figure 4As shown, the structure is used to stagger the fixing rods 41 to drive the liquid at different positions to flow, effectively taking away and dispersing a large amount of heat, thereby achieving a better cooling effect.

Figure 2 As shown, this structure is used to increase the air flow between the fans 54 by interlacing the fans 54, reduce the generation of eddies and dead corners, and thus improve the overall drying efficiency.

[0033] Working principle: When used, Figure 1 and Figure 2 As shown, the monofilament passes through the first guide wheel 3 and the four sets of rollers 42 in sequence. When the monofilament moves, the rollers 42 and the rotating blades 43 are driven to rotate on the surface of the fixed rod 41. When the rotating blades 43 rotate, the liquid in the cooling tank 1 flows, thereby taking away the heat of the monofilament and improving the cooling effect. The liquid inside the cooling tank 1 can be circulated and replaced through the water inlet pipe 44 and the water outlet pipe 45 respectively provided on both sides of the cooling tank 1. Figure 3 As shown, the monofilament passes through the drying box 51 and the surface of the two sets of second guide wheels 53, and the liquid on the surface of the monofilament is dried by the four sets of fans 54 on the top. At the same time, the liquid on the surface falls on the surface of the partition 52 and flows into the collection box 6 through the holes in the partition 52. The liquid is collected for recycling and avoids waste. The above is the entire working principle of the utility model.
