[0029] Plastics are important organic synthetic polymer materials with wide applications in daily life. Before injection molding, plastic granulation is usually required to improve product quality and processing convenience. In granulation of plastic materials, the materials are first mixed, then extruded into strips using an extruder. The extruded strips are then cooled in a water tank to harden for subsequent pelletizing. However, if the strips are immersed in the water for too short a time, they will not cool completely; if the immersion time is too long, the strips will have excessive moisture content. Furthermore, the strips will carry some water outside the tank after exiting, causing water accumulation and affecting product quality.

[0030] In this regard, one embodiment of this application provides a cooling device that can be used in a plastic granulation system to cool the strips extruded from an extruder.

[0031] like Figure 1 As shown, the cooling device 10 includes a water tank 100, a feed plate 200, and an air-cooling component 300. The water tank 100, as a water-cooling mechanism, primarily cools the extruded material strip from the extruder. Figure 1As shown, the water tank 100 has a feed end 110 and a discharge end 120 arranged opposite to each other. The feed end 110 is located near the extruder, and the discharge end 120 is located near the pelletizer. After the material strip is extruded from the extruder at high temperature, it will enter the water tank 100 through the feed end 110 of the water tank 100 for cooling under the traction of the pelletizer, and then continue to leave the water tank 100 through the discharge end 120 of the water tank 100 under the traction of the pelletizer.

[0032] The water tank 100 can be a rectangular water tank, an elliptical water tank, or a racetrack-shaped water tank, etc., and this application does not impose specific restrictions.

[0033] Optionally, the upper end of the water tank 100 is provided with a flange for mounting the feed plate 200 and the air-cooling component 300. The flange facilitates the installation of the feed plate 200 and the air-cooling component 300. Of course, in some other embodiments, the installation of the feed plate 200 and the air-cooling component 300 can be achieved by increasing the thickness of the side wall of the water tank 100.

[0034] like Figure 2 As shown, the feed plate 200 has multiple drainage holes 200a and can extend from the discharge end 120 toward the feed end 110 and be laid above the water tank 100. After the material strip leaves the discharge end 120 of the water tank 100 under the traction of the pelletizer, it can pass through the feed plate 200 and finally be pelletized by the pelletizer.

[0035] Optionally, the cooling device 10 also includes several guide wheels (not shown in the figures), which are disposed within the water tank 100 and can convey the material strip from the feed end 110 to the feed plate 200. The guide wheels guide the movement of the material strip, ensuring that the material strip can move smoothly from the feed end 110 of the water tank 100 to the discharge end 120 under the traction of the pelletizer, and then from the discharge end 120 to the feed plate 200. Optionally, the guide wheels are rotatably disposed within the water tank 100. This makes the conveying of the material strip less labor-intensive and reduces friction between the guide wheels and the material strip. This application does not impose specific limitations on the number of guide wheels or their arrangement in the water tank 100, as long as it effectively ensures that the material strip can be smoothly conveyed from the feed end 110 of the water tank 100 to the feed plate 200 under the traction of the pelletizer.

[0036] The air-cooling component 300 is positioned above the water tank 100 and can blow air onto the feed plate 200. When the water-cooled strip moves on the feed plate 200, the air-cooling component 300 blows cold air onto the strip on the feed plate 200, which can both continue to cool the strip and blow off the moisture on the strip so that the moisture on the strip can fall back into the water tank 100 through the drain hole 200a on the feed plate 200.

[0037] Optionally, the air-cooled component 300 can be a fan, with the fan's outlet facing the material feeding plate 200 laid on the water tank 100.

[0038] The size of the material walking plate 200 extending from the discharge end 120 to the feeding end 110 is adjustable, and the height of the air cooling member 300 is adjustable. When the temperature of the strip extruded by the extruder is high, the size of the material walking plate 200 extending from the discharge end 120 to the feeding end 110 is adjusted to be small, and the distance between the material walking plate 200 and the extruder is increased, so that the water passing time of the strip in the water tank 100 is increased, and the cooling effect of the strip is ensured. In this case, because the water passing time of the strip in the water tank 100 is too long, the water attached to the strip is too much when the strip leaves the water tank 100. In this case, the height of the air cooling member 300 is adjusted to be small (or the air volume of the air cooling member is increased at the same time), and the blowing strength of the air cooling member 300 to the strip is increased, so that the water on the strip can be effectively blown into the water tank 100. When the temperature of the strip extruded by the extruder is low, the size of the material walking plate 200 extending from the discharge end 120 to the feeding end 110 is adjusted to be large, and the height of the air cooling member 300 is adjusted to be large.

[0039] It can be seen that the cooling device 10 of the present application can adjust the size of the material walking plate 200 extending from the discharge end 120 to the feeding end 110 and the height of the air cooling member 300 according to the temperature of the strip extruded by the extruder, so that the water cooling effect of the water tank 100 and the air cooling effect of the air cooling member 300 to the strip can be ensured, the strip can be effectively and quickly cooled, the water on the strip can be effectively blown into the water tank 100 by the air cooling member 300, the ground water and water resource waste can be avoided, and the quality of the final product can be ensured.

[0040] As shown in FIG. 1, Figure 1 In some embodiments of the present application, the material walking plate 200 is made of shape memory material, and is wound on the side of the discharge end 120 in the original state. When the plastic is granulated, the material walking plate 200 can be laid on the top of the water tank 100 by applying a force to the material walking plate 200. The laying amount of the material walking plate 200 can be adjusted according to the temperature of the strip extruded by the extruder, and the material walking plate 200 not laid can be wound on the side of the discharge end 120 of the water tank 100 without occupying too much space. When the plastic granulation is finished, the force applied to the material walking plate 200 is removed, and the material walking plate 200 is reset according to its own characteristics, so that the material walking plate 200 is wound on the side of the discharge end 120 without occupying too much space.

[0041] Optionally, the material walking plate 200 can be made of high-strength shape memory alloy, such as nickel-titanium alloy.

[0042] Further, as shown in FIG. 1, Figure 1As shown, in some embodiments, a rotatable reel 400 is provided on the side of the discharge end 120, the first end of the feed plate 200 is connected to the reel 400, and the second end of the feed plate 200 can be laid on top of the water tank 100. The rotatable reel 400 facilitates the storage and unfolding of the feed plate 200.

[0043] During plastic granulation, to prevent the second end of the feed plate 200 from being wound onto the roll 400 without external force, in one embodiment, the top surface of the water tank 100 (i.e., the upper surface of the flange of the water tank 100 mentioned above) is provided with a plurality of first mounting positions spaced apart along the direction from the feed end 110 to the discharge end 120, and the second end of the feed plate 200 can be connected to any of the first mounting positions. After the amount of feed plate 200 laid is set according to the temperature of the strip when it is extruded from the extruder, the second end of the feed plate 200 can be connected to the corresponding first mounting position to fix the second end of the feed plate 200 and prevent the second end of the feed plate 200 from retracting.

[0044] Optionally, such as Figure 1 As shown, the top surface of the water tank 100 is provided with an inclined first buckle 130 at the first mounting position, and the second end of the feed plate 200 is provided with an inclined second buckle 210. The second buckle 210 is engaged with the first buckle 130. The engagement of the first buckle 130 and the second buckle 210 facilitates quick assembly and disassembly of the second end of the feed plate 200 from either of the first mounting positions.

[0045] Optionally, the water tank 100 has a first buckle 130 on both sides in the width direction, and the feed plate 200 has a second buckle 210 on both sides in the width direction, with the first buckle 130 and the second buckle 210 on the same side engaging. It should be noted that the direction from the feed end 110 to the discharge end 120 of the water tank 100 is the length direction of the water tank 100, and the width direction of the water tank 100 is perpendicular to the length direction of the water tank 100.

[0046] To ensure that the second end of the feed plate 200 lies flat on the water tank 100, such as Figure 1 As shown, in one embodiment, a guide wheel 500 is also provided on the side of the discharge end 120. The guide wheel 500 is located above the reel 400 and allows the feed plate 200 to pass through. The guide wheel 500 can guide the unfolding or retraction of the second end of the feed plate 200, and can also support the second end of the feed plate 200 to ensure that the second end of the feed plate 200 can be laid flat on the water tank 100.

[0047] Optionally, the guide wheel 500 is rotatably disposed on the side of the discharge end 120. This makes it easier to unfold or retract the second end of the feed plate 200.

[0048] like Figure 1As shown, in some embodiments of the present application, the top surface of the water tank 100 is provided with a mounting member 600, which is provided with a plurality of second mounting positions in the up-down direction, and the air cooling member 300 can be mounted on any second mounting position. The air cooling member 300 can be mounted on the corresponding second mounting position according to the temperature of the material strip when it is extruded from the extruder, so as to adjust the height of the air cooling member 300.

[0049] Optionally, as shown, Figure 2 As shown, the two sides of the top surface of the water tank 100 in the width direction are each provided with a mounting member 600, and the mounting member 600 on each side is provided with 2 in the direction from the feeding end 110 to the discharging end 120. In this way, the air cooling member 300 can be reliably arranged above the water tank 100. It should be noted that, in order to clearly describe the number and arrangement of the mounting member 600, the air cooler is not shown.

[0050] Optionally, as shown, Figure 1 As shown, the mounting member 600 is provided with an inclined third buckle 610 on the second mounting position, and the air cooling member 300 is provided with an inclined fourth buckle 310 at the air outlet thereof, and the third buckle 610 and the fourth buckle 310 are buckled. Through the buckling of the third buckle 610 and the fourth buckle 310, the air cooling member 300 and the mounting member 600 can be quickly disassembled, and the height of the air cooling member 300 can be adjusted.

[0051] As shown, Figure 1 As shown, in some embodiments of the present application, the cooling device 10 further comprises a support member 700 for supporting the water tank 100. The height of the water tank 100 can be increased by the support member 700, so that the feeding end 110 of the water tank 100 is aligned with the discharge port of the extruder.

[0052] Optionally, as shown, Figure 1 As shown, the support member 700 comprises a plurality of stand columns 710 arranged at the bottom of the water tank 100. The support member 700 of this structure is simple in structure and easy to assemble. The stand columns 710 can be connected with the water tank 100 by welding, screwing or the like.

[0053] The number and arrangement of the stand columns 710 are not limited in the present application, as long as the water tank 100 can be effectively supported. For example, two stand columns 710 are arranged on the left and right sides of the water tank 100, and one stand column 710 is arranged at the end of each side.

[0054] On the other hand, an embodiment of the present application provides a plastic granulation system, which comprises an extruder, a granulator and the cooling device 10 as described in any one of the above. The extruder is arranged close to the feeding end 110 of the cooling device 10, and the granulator is arranged close to the discharging end 120 of the cooling device 10.

[0055] The plastic pelletizing system of the present application can adjust the size of the material guide plate 200 extending from the discharge end 120 to the feeding end 110 and the height of the air cooling member 300 according to the temperature of the material strip when it is extruded from the plastic extruder, so as to ensure the water cooling effect of the water tank 100 on the material strip and the air cooling effect of the air cooling member 300 on the material strip, effectively and quickly cool the material strip, effectively blow the water on the material strip into the water tank 100 by the air cooling member 300, avoid the waste of ground water and water resources, and ensure the quality of the final product.

[0056] As shown in the drawings, Figure 1 In some embodiments of the present application, the material guide plate 200 is made of shape memory material and is wound on the side of the discharge end 120 in the original state. When the plastic is pelletized, the material guide plate 200 can be laid on the top of the water tank 100 by applying a force to the material guide plate 200. The laying amount of the material guide plate 200 can be set according to the temperature of the material strip when it is extruded from the plastic extruder. The material guide plate 200 that is not laid can be wound on the side of the discharge end 120 of the water tank 100 without occupying too much space. When the plastic pelletizing is completed, the force applied to the material guide plate 200 is removed. The material guide plate 200 is reset according to its own characteristics and is wound on the side of the discharge end 120 without occupying too much space.

[0057] Optionally, the material guide plate 200 can be made of high-strength shape memory alloy, such as nickel-titanium alloy.

[0058] Further, as shown in the drawings, Figure 1 In some embodiments, a rotatable reel 400 is arranged on the side of the discharge end 120. The first end of the material guide plate 200 is connected to the reel 400, and the second end of the material guide plate 200 can be laid on the top of the water tank 100. The rotatable reel 400 facilitates the storage and deployment of the material guide plate 200.

[0059] During the plastic pelletizing, in order to avoid the second end of the material guide plate 200 from being wound on the reel 400 without external force, in an embodiment, the top surface of the water tank 100 (i.e. the upper surface of the flange of the water tank 100 mentioned above) is provided with a plurality of first mounting positions in the direction from the feeding end 110 to the discharge end 120. The second end of the material guide plate 200 can be connected to any first mounting position. When the laying amount of the material guide plate 200 is set according to the temperature of the material strip when it is extruded from the plastic extruder, the second end of the material guide plate 200 can be connected to the corresponding first mounting position to fix the second end of the material guide plate 200 and avoid the second end of the material guide plate 200 from retracting.

[0060] Optionally, as shown in the drawings, Figure 1As shown, the top surface of the water tank 100 is provided with an inclined first buckle 130 at the first mounting position, and the second end of the feed plate 200 is provided with an inclined second buckle 210. The second buckle 210 is engaged with the first buckle 130. The engagement of the first buckle 130 and the second buckle 210 facilitates quick assembly and disassembly of the second end of the feed plate 200 from either of the first mounting positions.

[0061] Optionally, the water tank 100 has a first buckle 130 on both sides in the width direction, and the feed plate 200 has a second buckle 210 on both sides in the width direction, with the first buckle 130 and the second buckle 210 on the same side engaging. It should be noted that the direction from the feed end 110 to the discharge end 120 of the water tank 100 is the length direction of the water tank 100, and the width direction of the water tank 100 is perpendicular to the length direction of the water tank 100.

[0062] To ensure that the second end of the feed plate 200 lies flat on the water tank 100, such as Figure 1 As shown, in one embodiment, a guide wheel 500 is also provided on the side of the discharge end 120. The guide wheel 500 is located above the reel 400 and allows the feed plate 200 to pass through. The guide wheel 500 can guide the unfolding or retraction of the second end of the feed plate 200, and can also support the second end of the feed plate 200 to ensure that the second end of the feed plate 200 can be laid flat on the water tank 100.

[0063] Optionally, the guide wheel 500 is rotatably disposed on the side of the discharge end 120. This makes it easier to unfold or retract the second end of the feed plate 200.

[0064] like Figure 2 As shown in some embodiments of this application, the top surface of the water tank 100 is provided with a mounting member 600, and the mounting member 600 is provided with a plurality of second mounting positions spaced apart in the vertical direction. The air-cooling component 300 can be installed in any of the second mounting positions. The height of the air-cooling component 300 can be adjusted by installing the air-cooling component 300 in the corresponding second mounting position according to the temperature of the material strip when it is extruded from the extruder.

[0065] Optionally, such as Figure 1 As shown, mounting members 600 are provided on both sides of the top surface of the water tank 100 in the width direction, with two mounting members 600 on each side spaced apart along the direction from the feed end 110 to the discharge end 120. This arrangement allows the air-cooled component 300 to be reliably positioned above the water tank 100. It should be noted that, for the sake of clear description of the number and arrangement of the mounting members 600, the air-cooled unit is not shown.

[0066] Optionally, such as Figure 1As shown, the mounting member 600 is provided with an inclined third buckle 610 at the second mounting position, and the air cooling member 300 is provided with an inclined fourth buckle 310 at the air outlet of the air cooling member 300, and the third buckle 610 is buckled with the fourth buckle 310. Through the buckling of the third buckle 610 and the fourth buckle 310, the air cooling member 300 and the mounting member 600 can be quickly disassembled, and the height of the air cooling member 300 can be adjusted.

[0067] As shown, Figure 1 In some embodiments of the present application, the cooling device 10 further comprises a support member 700 for supporting the water tank 100. Through the support member 700, the height of the water tank 100 can be increased, so that the feed end 110 of the water tank 100 is aligned with the discharge port of the extruder.

[0068] Optionally, as shown, ​ The support member 700 comprises a plurality of vertical columns 710 arranged at the bottom of the water tank 100. The support member 700 of this structure is simple in structure and easy to assemble. The vertical columns 710 can be connected with the water tank 100 by welding, screwing or other methods.

[0069] The number and arrangement of the vertical columns 710 are not limited in the present application, as long as the water tank 100 can be effectively supported. For example, two vertical columns 710 are arranged on the left and right sides of the water tank 100 respectively, and one vertical column 710 is arranged at the end of each side.
