Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A drainage component is installed inside the cooling roller 1, which passes through the hollow end 2 and extends to the outside of the blocking member 5. The drainage component is used to quickly drain the water in the inner cavity of the cooling roller 1;

[0028] A sleeve assembly is provided at the end of the drainage assembly, and the sleeve assembly is used to protect the outer ends of the drainage pipe 6 and the water inlet pipe 7.

[0029] In this embodiment: when the device is used to cool plastic products, the water inlet pump connected to the water inlet pipe 7 is turned on, the water inlet pump pumps cooling water into the interior of the water inlet pipe 7, and sprays it into the inner wall surface of the cooling roller 1 through the nozzle 8, so as to quickly cool the cooling roller 1, so that the plastic products passing through the outer surface of the cooling roller 1 are quickly cooled and formed, and the cooling water that contacts the inner wall of the cooling roller 1 falls downward after a heat exchange reaction and falls into the drainage component. The drainage component extracts the cooling water after the heat exchange and discharges it to the outside of the device, thereby avoiding the accumulation of cooling water on the inner wall of the cooling roller 1 after the heat exchange.

[0030] Please refer to Figure 2 and Figure 3, the drainage assembly includes: a drainage pipe 6, a receiving plate 9, an inclined surface 10, a raised portion 11 and a guide surface 12;

[0031] The drain pipe 6 is inserted from the outside of the connection cover 4 into the inner cavity of the hollow end head 2 and the connection head 3, and extends to the inner cavity of the cooling roller 1. The inner cavity of the cooling roller 1 is provided with a receiving plate 9, and the top edge of the receiving plate 9 is formed with a slope 10;

[0032] A bulge 11 protruding upward is formed at the bottom of the inner cavity of the receiving plate 9, and guide surfaces 12 are formed on both sides of the bulge 11, and a water accumulation space is formed between the guide surface 12 and the end plate of the receiving plate 9;

[0033] The end of the receiving plate 9 is located in the water accumulation space.

[0034] In this embodiment: when the cooling water after heat exchange is discharged, the drainage pump connected to the drainage pipe 6 is started, and the drainage pump pumps out the cooling water accumulated in the water accumulation space through the drainage pipe 6;

[0035] After the cooling water cools the inner wall of the cooling roller 1, the cooling water falls downward into the receiving plate 9 under the action of gravity. When part of the cooling water contacts the inclined surface 10 and the raised portion 11, the cooling water is guided into the water accumulation space through the contact between the inclined surface 10 and the guide surface 12, so that the drain pipe 6 can better extract the cooling water after heat exchange.

[0036] Please refer to Figure 3 , the casing assembly includes: a first support frame 13 and a second support frame 14;

[0037] The No. 1 support frame 13 is used to protect one end of the drain pipe 6 , and the No. 1 support frame 13 is used to protect one end of the water inlet pipe 7 . The water inlet pipe 7 is inserted into the inner cavity of the connector 3 from the outside of the connecting cover 4 and extends to the inner wall of the other connecting cover 4 .

[0038] In this embodiment: a No. 1 support frame 13 with a hollow structure is connected to a water inlet pipe opening on a connecting cover 4, and two No. 2 support frames 14 are respectively connected to the drainage pipe openings on the two connecting covers 4. Therefore, the No. 1 support frame 13 and the No. 2 support frame 14 are fixedly connected to the connecting cover 4, which can protect the position where the drainage pipe 6 and the water inlet pipe 7 enter the interior of the device.

[0039] Please refer to Figure 2 The water inlet pipe 7 is located in the inner cavity of the cooling roller 1 and is equidistantly provided with a plurality of nozzles 8. The nozzles 8 filled with water are used to cool the rotating cooling roller 1.

[0040] In this embodiment: the water pump connected to the water inlet pipe 7 is started. Under the pressure of the water pump, cooling water enters the interior of the water inlet pipe 7 and is sprayed out from multiple nozzles 8. The sprayed cooling water contacts the inner wall surface of the cooling roller 1, thereby achieving a heat exchange cooling effect.

[0041] Please refer to Figure 3 The outer wall of the plugging member 5 is provided with a static seal, the inner wall of the hollow end 2 is provided with a dynamic seal, and the plugging member 5 is provided with holes and grooves for inserting the water supply and drainage pipe 6 and the water inlet pipe 7.

[0042] In this embodiment: when the hollow end head 2 rotates with the cooling roller 1, the static seal on the blocking member 5 and the dynamic seal on the outer wall of the hollow end head 2 always keep in contact with each other, thereby achieving a rotating sealing effect;

[0043] The drain pipe 6 and the water inlet pipe 7 are inserted into the device from the outside, and the holes and grooves on the blocking member 5 can avoid the problem of the drain pipe 6 and the water inlet pipe 7 being blocked during insertion.

[0044] Please refer to Figure 2 A support ring is formed on the top of the end plate of the receiving plate 9, and the support ring is sleeved on the outside of the water inlet pipe 7. The end plate of the receiving plate 9 is located below the support ring and is provided with a connecting hole for inserting the water supply and drainage pipe 6.

[0045] In this embodiment: the receiving plate 9 is connected to the water inlet pipe 7 and the drain pipe 6, and the water inlet pipe 7 and the drain pipe 6 will not rotate with the cooling roller 1, so the receiving plate 9 always remains stationary, and can receive the cooling water dripping downwards no matter how the cooling roller 1 rotates.

[0046] Please refer to Figure 2 , the bottom end of the receiving plate 9 does not contact the inner wall of the cooling roller 1.

[0047] In this embodiment, reducing the contact area between the receiving plate 9 and the cooling roller 1 can better reduce the friction between the two, thereby further reducing wear.

[0048] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
