[0002] EVA is the English abbreviation of ethylene-vinyl acetate copolymer. It is a random copolymer composed of non-polar, crystalline ethylene monomers and highly polar, non-crystalline vinyl acetate monomers (also known as VA). EVA has a wide range of applications. my country's annual market consumption is increasing. Shoe materials are the main application field of EVA resin in my country. In the EVA resin used in shoe materials, the vinyl acetate content is generally 15% to 22%. Because EVA resin blended foam products have the properties of softness, good elasticity, and chemical corrosion resistance, they are widely used in the soles and interior materials of mid-to-high-end tourist shoes, mountaineering shoes, slippers, and sandals.

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] As shown in the figure, the present embodiment provides a cooling device for preparing EVA particles, including a fixed inclined plate 1, which is slightly inclined at a certain angle, which is conducive to the subsequent unloading of the cooling device, and a support plate 2 and a support plate 6 are respectively installed on the top outer wall of the fixed inclined plate 1, and a support main shaft 3 is rotatably connected to the support plate 2, and a fixed side plate 4 is installed at one end of the support main shaft 3, and a cooling roller 5 is installed on one side wall of the fixed side plate 4, and air holes are respectively opened on the side walls of the cooling roller 5, and an air outlet transverse pipe 7 is fixedly installed on the support plate 2 6, and an air outlet disk 8 is installed on the side wall of the air outlet transverse pipe 7, and a side cover 11 is slidably connected to the side wall of the air outlet transverse pipe 7, and a cooling air box 9 and a blower 12 are respectively arranged on the top outer wall of the fixed inclined plate 1, and the cooling air box 9 and the air outlet disk 8 are respectively provided with jet holes, and the jet holes on the air outlet disk 8 and the air outlet transverse pipe 7 are connected to the side wall of the air outlet transverse pipe 7. The pipe 7 is connected, the output end of the blower 12 is connected to the cooling air box 9, and a cooling coil 10 is arranged inside the cooling air box 9. The cooling coil 10 has two ends, one end of which is connected to an external cooling water source, and the other end transports the water back to the cooling tower. A driving motor 17 is arranged on the top outer wall of the fixed inclined plate 1, and the output end of the driving motor 17 is connected to a driving pulley 19. A driven pulley 18 is installed at one end of the support main shaft 3 away from the fixed side plate 4, and the driven pulley 18 is connected to the driving pulley 19 through a transmission belt. Support side plates 13 are respectively installed on the side walls of the cooling drum 5, and a threaded rod 14 is installed on one side wall of the support side plate 13. A locking nut 15 is connected to the thread on the outer surface of the threaded rod 14. A clamping groove 16 is opened on the side cover 11, and a feed hole is opened on the side wall of the cooling drum 5, and a material cover 20 is arranged on the feed hole.

[0022] When it is necessary to cool the particles, the particles to be cooled can be added to the cooling drum 5 through the feeding holes on the side wall of the cooling drum 5. After the feeding is completed, the material cover 20 is installed, and air is blown into the cooling air box 9 through the blower 12, so that the air is cooled by the cooling coil 10 and then ejected from the jet holes on the top of the cooling air box 9, so that the particles inside the cooling drum 5 can be cooled. At the same time, the driving pulley 19 is driven to rotate by the driving motor 17, so that the supporting main shaft 3 can drive the cooling drum 5 to rotate through the fixed side plate 4. The air inside the cooling air box 9 can also enter the air outlet cross pipe 7 and be ejected through the jet holes on the air outlet plate 8. When the cooling drum 5 is rotating and the air outlet plate 8 is stationary, the air outlet plate 8 It can stir the particles inside the cooling drum 5 and blow out air through the air outlet plate 8, so that the cooling device can effectively cool the particles in the center of the cooling drum 5. When unloading is required, first slightly loosen the locking nut 15 and rotate the side cover 11 so that the large head of the snap-in groove 16 is aligned with the locking nut 15. Then the side cover 11 can be pulled open so that the side cover 11 no longer covers the side of the cooling drum 5, so that the particles inside the cooling drum 5 can flow out from one end of the cooling drum 5. The unloading method of the cooling device can not only unload the materials effectively, but also there will be no dead corners in the cooling drum 5 that cannot be cooled by the cooling air, which can further improve the cooling effect of the cooling device on the particles.

[0023] A limit ring 23 is installed on the side wall of the cooling drum 5, and a support frame 21 is installed on the top outer wall of the fixed inclined plate 1. A support wheel 22 is rotatably connected to the support frame 21. The support wheel 22 supports one end of the cooling drum 5, which is conducive to improving the stability of the cooling drum 5 when it rotates. A guide plate 25 is set on the top outer wall of the fixed inclined plate 1. The material flowing out of one end of the cooling drum 5 falls onto the guide plate 25 and is guided away by the guide plate 25. A sealing gasket 24 is installed on one side wall of the side cover 11. The sealing gasket 24 is conducive to improving the sealing performance between the side cover 11 and the side wall of the cooling drum 5.

[0024] When the utility model is in use, the particles to be cooled are added into the cooling drum 5 through the feeding holes on the side wall of the cooling drum 5, and then the material cover 20 is covered, and then the driving pulley 19 is driven to rotate by the driving motor 17, so that the supporting main shaft 3 can drive the cooling drum 5 to rotate through the fixed side plate 4, and the blower 12 is used to blow air into the cooling air box 9, so that the air is cooled by the cooling coil 10 and then ejected from the jet holes on the top of the cooling air box 9, so that the particles inside the cooling drum 5 can be cooled. At the same time, the air can also enter the air outlet transverse pipe 7, and then be ejected through the jet holes on the air outlet plate 8. The cooling drum 5 rotates while the air outlet plate 8 is stationary, so that the air outlet plate 8 It can stir the particles inside the cooling drum 5 and blow out air through the air outlet plate 8, so that the cooling device can also effectively cool the particles in the center of the cooling drum 5. When unloading is needed, the locking nut 15 is slightly loosened and the side cover 11 is rotated to align the large end of the snap-in groove 16 with the locking nut 15. Then the side cover 11 can be pulled so that it no longer covers the side of the cooling drum 5, so that the particles inside the cooling drum 5 can all flow out from one end of the cooling drum 5. This unloading method can not only unload the materials effectively, but also there will be no dead corners in the cooling drum 5 that cannot be cooled by the cooling air, thereby further improving the cooling effect of the cooling device on the particles.
