[0006] Preferably, coolant delivery connectors are rotatably mounted at both ends of the roller drive end, and through holes communicating with the connecting hole and the coolant jacket are opened in the coolant delivery connector.

[0007] Preferably, the fastening end is sealed to both the roll body and the roll drive end, and the flow channel connecting hole is an annular structure.

[0008] Preferably, the portion of the connecting hole that connects to the flow channel connecting hole has a cross-shaped hole structure.

[0009] Preferably, the outer cooling cover of the roll has a fan-shaped structure, and the coolant jacket corresponds to the installation position of the cooling airflow delivery pipe and the air-cooled fan.

[0010] Preferably, a fan is screwed to the outer side of the outer cooling cover of the roll, and a connecting pipe is connected to the air outlet of the fan, and the connecting pipe is connected to the cooling airflow delivery pipe through a pipe fitting.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This coolable roll combines internal liquid cooling and external air cooling, and uses an external cooling cover with a coolant jacket to fix the cooling airflow delivery pipe, which further improves the cooling effect of the roll, ensures production quality, and extends the service life of the equipment. The external cooling cover is fixed to the coolant delivery connector, allowing the connector to simultaneously supply coolant to both the coolant flow channel and the coolant jacket. This ensures efficient internal cooling while improving external cooling performance, and the external cooling cover also provides cooling and protection for the air-cooled fan.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a coolable roll, including a roll body 1, with parallel coolant channels 101 evenly spaced on the side of the roll body 1, and roll drive ends 3 integrally formed at both ends of the roll body 1. Each roll drive end 3 has a connecting hole 301, and a fastening end 2 is fitted onto the roll drive end 3. The fastening end 2 has a channel connecting hole 201 that communicates with the coolant channels 101 and the connecting hole 301. The fastening end 2 is sealed to both the roll body 1 and the roll drive end 3. The channel connecting hole 201 has an annular structure, allowing the coolant channels 101 to flow through the channel connecting hole 201. The 01 and the connecting hole 301 are reliably connected to ensure the entry and exit of coolant. The part where the connecting hole 301 connects with the flow channel connecting hole 201 has a cross-shaped hole structure. This structure ensures that the connecting hole 301 can evenly distribute the coolant into the flow channel connecting hole 201, and then the flow channel connecting hole 201 evenly distributes the coolant into the coolant flow channel 101. A roll outer cooling cover 4 is provided above the roll body 1, and a coolant jacket 401 is provided inside the roll outer cooling cover 4. Coolant delivery connecting seats 5 are rotatably installed at both ends of the roll drive end 3, and through holes communicating with the connecting hole 301 and the coolant jacket 401 are opened in the coolant delivery connecting seats 5. This structure connects the roll body 1 to the cooling system pipeline via the coolant delivery connector 5. The coolant delivery connector 5 also serves to rotate and position the roll body 1, and securely mounts the outer cooling cover 4. The inner side of the outer cooling cover 4 is equipped with a cooling airflow delivery pipe 7, and cooling air nozzles 701 are evenly spaced on the cooling airflow delivery pipe 7, pointing towards the roll body 1. A fan 6 is screwed to the outer side of the outer cooling cover 4, and the outlet of the fan 6 is connected to a connecting pipe 601. The connecting pipe 601 and the cooling airflow delivery pipe 7 are connected via fittings. This structure utilizes existing... Some air-cooled fans 6 can perform air cooling, so that the cold air nozzles 701 spray cold air to the outside of the roll body 1, accelerate the air flow, and achieve the purpose of cooling. The roll outer cooling cover 4 has a fan-shaped structure, and the coolant jacket 401 corresponds to the installation position of the cooling air flow pipe 7 and the air-cooled fan 6. This structure allows for the installation and positioning of the cooling air flow pipe 7 and the air-cooled fan 6 through the roll outer cooling cover 4. At the same time, the coolant flows in the coolant jacket 401, which can achieve the cooling treatment of the installation position of the air-cooled fan 6, protect the air-cooled fan 6, and remove the heat of the area covered by the roll outer cooling cover 4, ensuring the cooling effect of the roll body 1.

[0019] Working principle: When using this coolable roll, the roll body 1 first connects to the drive mechanism through the roll drive end 3 during operation, realizing the rotation of the roll body 1. Coolant enters the connecting hole 301 and the coolant jacket 401 through the coolant delivery connector 5. The coolant in the connecting hole 301 enters the flow channel connecting hole 201 and is distributed in the coolant flow channel 101. The fastening end 2 is used for sealing and fastening the flow channel connecting hole 201 and the coolant flow channel 101. The coolant in the coolant jacket 401 flows through the installation position of the cooling air delivery pipe 7 and the air-cooled fan 6 and then enters the coolant delivery connector 5 at the outlet end. The roll outer cooling cover 4 is used for the installation and positioning of the cooling air delivery pipe 7 and the air-cooled fan 6. The cold air generated by the air-cooled fan 6 enters the cooling air delivery pipe 7 through the connecting pipe 601 and is then sprayed onto the outer surface of the roll body 1 by the cold air nozzle 701, realizing the efficient cooling treatment of the roll body 1, thereby completing a series of operations.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
