[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0040] like Figure 1-6 As shown, a conveyor roller integrating heating and cooling includes an outer roller 1 and an inner roller 2 coaxially arranged. The inner roller 2 includes an inner roller support 21, which includes a partition 211 and an inner roller support 212 connected to both ends of the partition 211. A fixed shaft 213 is provided at one end of the inner roller support 212 away from the partition 211. The inner roller support 21 is fixedly connected to the outside through the fixed shaft 213.

[0041] The outer roller 1 is driven to rotate by an external motor. The outer roller 1 includes an outer roller wall 11, which is sleeved on the outside of the inner roller support 21. The two ends of the outer roller wall 11 are rotatably connected to the inner roller support 21 through the outer roller bearing 3.

[0042] The partition 211 divides the chamber between the outer roller wall 11 and the inner roller support 21 into a heating chamber 10 and a cooling chamber 20.

[0043] The fixed shaft 213 has a first through hole 213a that connects the heating chamber 10 to the outside, and a second through hole 213b that connects the cooling chamber 20 to the outside.

[0044] Pipe interfaces 4 are respectively provided on the ports of the first through hole 213a and the second through hole 213b.

[0045] In this embodiment, an external motor drives the outer roller wall 11 to rotate, thereby conveying the film. Due to the arrangement of the cooling chamber 20 and the heating chamber 10, different areas of the rotating outer roller wall 11 are heated and cooled, thereby realizing the heating or cooling of the conveyed film through a single conveying roller, simplifying the equipment structure, reducing the equipment operating space, and improving the film production efficiency.

[0046] In this embodiment, the heating chamber 10 is equipped with a heating component to conduct heat to the outer roller 1, or it is connected to an external heating oil system to conduct heat to the outer roller 1 through the heating oil; the cooling chamber 20 is connected to an external cooling water system or cooling air system to conduct cold energy to the outer roller 1 through the cooling water or cooling air.

[0047] In this embodiment, the fixed shaft 213 can be fixedly connected to the external frame via the outer roller fixing block 5.

[0048] Furthermore, such as Figure 1 , 2 As shown, the outer roller 1 also includes an outer roller support 12 fixedly connected to both ends of the outer roller wall 11, and the outer roller support 12 is rotatably connected to the fixed shaft 213 through the outer roller bearing 3.

[0049] The inner roller 2 also includes an inner roller wall 22, which is located between the outer roller wall 11 and the inner roller 2. The inner roller wall 22 is sealed to the inner roller support 21. The inner roller wall 22 is used to seal the heating chamber 10 and the cooling chamber 20 to the outer roller wall 11.

[0050] The heating chamber 10 is connected to an external heating oil system through a first through hole 213a, and the cooling chamber 20 is connected to an external cooling water system through a second through hole 213b.

[0051] In this embodiment, the inner roller wall 22 and the inner roller support 21 are sealed and welded together. During operation, heating oil and cooling water are circulated into the heating chamber 10 and the cooling chamber 20 respectively, thereby heating and cooling different areas of the outer roller 1, so as to realize the heating or cooling of the conveyed film through a single conveying roller.

[0052] In the above structure, the heat conduction between the outer roller wall 11 and the inner roller wall 22 is radiation conduction. The gap between the mating surfaces of the roller walls is 0.2 mm to 0.5 mm. The material of the mating surfaces of the rollers is a material with good thermal conductivity to facilitate heating or cooling.

[0053] Furthermore, such as Figure 1 , 3 As shown in Figure 4, a high-density elastic wear-resistant sealing ring 6 is provided between the inner roller support 21 and the outer roller wall 11. The high-density elastic wear-resistant sealing ring 6 is used to seal the heating chamber 10 and the cooling chamber 20 with the outer roller wall 11.

[0054] The heating chamber 10 is equipped with an infrared heating tube group 30 or is connected to an external heating oil system through a first through hole 213a. The cooling chamber 20 is connected to an external cooling water system or cooling air system through a second through hole 213b.

[0055] In this embodiment, when the heating chamber 10 is connected to the external heating oil system through the first through hole 213a, and the cooling chamber 20 is connected to the external cooling water system through the second through hole 213b, the heat transfer between the outer roller 1 and the inner roller 2 can be conducted through contact. A high-density elastic wear-resistant sealing ring 6 is used to replace the inner roller wall 22 and is installed on the inner roller bracket 21 to seal the heating chamber 10 and cooling chamber 20 with the outer roller wall 11. This allows for relative rotation of the outer roller 1, and the heating oil and cooling water can directly contact the outer roller wall 11 to conduct heat.

[0056] Furthermore, such as Figure 4 As shown, the heating chamber 10 is equipped with an infrared heating tube group 30 and a first temperature sensor 40, the cooling chamber 20 is connected to an external cooling gas system through a second through hole 213b, and a second temperature sensor 50 is installed inside the cooling chamber 20.

[0057] In this embodiment, the heating chamber 10 is equipped with an infrared heating tube group 30 and a first temperature sensor, and the cooling chamber 20 is connected to an external cooling gas system; the outer roller 1 is directly and controllably heated and cooled by infrared heating and cooling gas.

[0058] Furthermore, such as Figure 5 , 6 As shown, the two ends of the outer roller wall 11 are rotatably connected to the inner roller support 212 via the outer roller bearing 3;

[0059] The inner roller 2 also includes a plurality of first small rollers 7 rotatably disposed in the heating chamber 10, and a plurality of second small rollers 8 rotatably disposed in the cooling chamber 20;

[0060] The first small roller 7 or the second small roller 8 is provided with connecting shafts 71 at both ends, and the connecting shafts 71 are provided with a third through hole 71a that communicates with the inner cavity of the first small roller 7.

[0061] The connecting shaft 71 is rotatably connected to the shaft hole of the inner roller support 212, and a mounting bearing 60 is provided between the connecting shaft 71 and the shaft hole; the first small roller 7 and the second small roller 8 are in contact with the inner wall of the outer roller wall 11.

[0062] Each end of the connecting shaft 71 is provided with a rotating connector 9;

[0063] The inner cavity of the first small roller 7 is connected to the external heating oil system through the third through hole 71a and the rotary connector 9; the inner cavity of the second small roller 8 is connected to the external cooling water system through the third through hole 71a and the rotary connector.

[0064] In this embodiment, the heat conduction between the outer roller 1 and the first small roller 7 is through contact conduction. The rotation of the outer roller 1 drives the first small roller 7 and the second small roller 8 to rotate. At the same time, the heat of the hot oil in the first small roller 7 is conducted to the outer roller 1 through contact, and the cooling energy of the cooling water in the second small roller 8 is conducted to the outer roller 1 through contact. This achieves heating and cooling of the outer roller 1. In addition, the size of the heating and cooling area of ​​the conveyor roller can be adjusted by adjusting the number of small rollers and the selection of heating and cooling.

[0065] Furthermore, such as Figure 5 , 6 As shown, the first small roller 7 or the second small roller 8 is provided with an external drive protrusion 72, and the inner side of the outer roller wall 11 is provided with an internal drive concave tooth 11a. The external drive protrusion 72 and the internal drive concave tooth 11a are meshed and connected to each other.

[0066] In this embodiment, the outer roller 1 can be rotated by driving the first small roller 7 or the second small roller 8 to rotate through an external driver, thereby realizing the transport of the film.

[0067] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
