[0002] A calender is a device widely used in multiple industries, especially playing an important role in fields such as textile and printing. It is mainly used to improve the glossiness and flatness of the material surface. Through continuous rolling, under the combined action of temperature, pressure, and speed, the material surface reaches an ideal gloss effect. A calender usually includes a printed matter conveying mechanism, mechanical transmission, an electrical control system, etc. Among them, the hot pressing roller and the pressure roller are key components. A calendering belt is clamped between them, and the calendering treatment of the material is achieved through heating and pressurization. During the operation process, the operator needs to adjust parameters such as temperature, pressure, and speed according to specific requirements to obtain the best calendering effect.

[0003] After the rubber roller of the calender has been used for a long time, grooves will be generated, resulting in uneven thickness of the calendered product and inability to meet the product technical performance requirements. When grooves are generated on the rubber roller, the heating roller needs to be heated to 120 °C, and the rubber roller is pressed flat through high temperature and high pressure. After the rubber roller is pressed flat, it takes a long time to cool down with a blower. For this reason, a circulating water cooling device for a calender is proposed. Content of the Utility Model

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 and Figure 5 shown, the present utility model provides a technical solution for a calender circulating water cooling and temperature reduction device, including an equipment frame 1, a positioning pillar 4 fixedly installed on the equipment frame 1, a heating roller 2 movably installed on the equipment frame 1, a rubber roller 3 movably installed below the heating roller 2, a cooling mechanism 5 connected to the rubber roller 3. The cooling mechanism 5 includes a heat absorption pipeline 505 fixed inside the rubber roller 3, a heat dissipation mechanism 6 fixedly installed at the upper end of the buffer box 501, and heat dissipation fins 604 fixedly installed on the heat dissipation copper pipe 603. By the combined use of the cooling mechanism 5 and the heat dissipation mechanism 6, the cooling liquid can circulate to cool the rubber roller 3, improving the speed of roller cooling.

[0023] As Figure 2 and Figure 3As shown, a cooling mechanism 5 is connected to the rubber roller 3. The cooling mechanism 5 includes a heat absorption pipeline 505 fixed inside the rubber roller 3. On one side of the equipment frame 1, a buffer box 501 is fixedly installed. Inside the buffer box 501, a turbine pump 502 is fixedly installed. A delivery pipeline 503 is connected to the turbine pump 502, and the delivery pipeline 503 is communicated with the heat absorption pipeline 505. On one side of the heat absorption pipeline 505, there is a liquid inlet 506, and on the other side of the heat absorption pipeline 505, there is a liquid outlet 507. Rotating connectors 504 are provided on both the liquid inlet 506 and the liquid outlet 507.

[0024] Specifically, the drive motor 602 can drive the drive shaft 607 to rotate. After the drive shaft 607 rotates, it will drive the impeller inside the turbine pump 502 to rotate. After the impeller inside the turbine pump 502 rotates, it will pump the coolant in the buffer box 501 into the heat absorption pipeline 505. After the coolant is pumped into the heat absorption pipeline 505, it will exchange heat with the rubber roller 3, quickly reducing the temperature of the rubber on the surface of the rubber roller 3.

[0025] As Figure 2 , Figure 4 and Figure 5 shown, the heat dissipation mechanism 6 includes a positioning frame 601 fixedly installed above the buffer box 501. Inside the positioning frame 601, a heat dissipation copper pipe 603 and a positioning rod 609 are fixedly installed. Heat dissipation fins 604 are fixedly installed on the heat dissipation copper pipe 603. A fan blade 605 is movably installed on the positioning rod 609. A drive motor 602 is fixedly installed at the upper end of the positioning frame 601. The output end of the drive motor 602 is fixedly installed with a drive shaft 607, and the end of the drive shaft 607 is connected to the drive end of the turbine pump 502. On one side of the drive shaft 607, there is a transmission shaft 608. Helical gears 606 are provided on both the drive shaft 607 and the transmission shaft 608, and the helical gears 606 are meshed with each other in pairs.

[0026] Specifically, the drive shaft 607 can drive the transmission shaft 607 to rotate. When the transmission shaft 607 rotates, it will drive the fan blade 605 to rotate. After the fan blade 605 rotates, it will drive the air to quickly blow towards the heat dissipation fins 604, thereby driving away the heat on the heat dissipation fins 604, reducing the temperature of the coolant. After the temperature of the coolant is reduced, it will flow back into the buffer box 501 again, enabling the coolant to be recycled.

[0027] Working principle: When in use, first start the drive motor 602. After starting the drive motor 602, it will drive the drive shaft 607 to rotate. After the drive shaft 607 rotates, it will drive the impeller inside the turbine pump 502 to rotate. After the impeller inside the turbine pump 502 rotates, it will pump the coolant in the buffer box 501 into the heat absorption pipeline 505. After the coolant is pumped into the heat absorption pipeline 505, it will exchange heat with the rubber roller 3, rapidly reducing the temperature of the rubber on the surface of the rubber roller 3. After the temperature of the rubber on the surface of the rubber roller 3 decreases, the temperature of the coolant will increase. After the temperature of the coolant increases, it will flow through the heat dissipation copper pipe 603. When the high-temperature coolant flows through the heat dissipation copper pipe 603, it will conduct heat to the heat dissipation fins 604. When the heat is conducted to the heat dissipation fins 604, the drive shaft 607 will drive the transmission shaft 607 to rotate under the action of the helical gear 606. Since helical gears 606 are provided on both the drive shaft 607 and the transmission shaft 608, and the helical gears 606 are meshed pairwise, when the transmission shaft 607 rotates, it will drive the fan blade 605 to rotate. After the fan blade 605 rotates, it will drive the air to quickly blow towards the heat dissipation fins 604, thereby driving away the heat on the heat dissipation fins 604 and reducing the temperature of the coolant. After the temperature of the coolant decreases, it will flow back into the buffer box 501 again. Repeating this cycle can improve the speed of roller cooling.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
