[0002] A heat exchange roller is a device used in industrial production to achieve heat exchange, conveying heat transfer media such as water, oil, or steam through internal channels. In the production process of lithium battery separators, heat exchange rollers are commonly used to control the temperature of the separator.
[0003] Existing heat exchange rollers generally include a roller body and two rotary joints connected to both ends of the roller body. A heat exchange channel is provided inside the roller body. One rotary joint is connected to an inlet pipe, and the other is connected to an outlet pipe. Both the inlet and outlet pipes are connected to the heat exchange channel. In use, the heat exchange medium enters the heat exchange channel through the inlet pipe for heat exchange, and then flows out through the outlet pipe. For example, patent CN215983406U discloses an internal jet cooling roller that uses this structure. However, in the prior art, the heat exchange medium inlet and outlet are located at opposite ends of the roller, and the rotary joints generally only have one or the other inlet pipe installed. When it is necessary to place the inlet and outlet pipes at the same end of the roller, the existing rotary joints cannot meet the requirements. Summary of the Invention

[0008] The outer periphery of the connector body is provided with a sealing part protruding in the circumferential direction.
[0009] Furthermore, the inlet pipe mounting hole and the outlet pipe mounting hole are coaxial and their central axes are collinear with the central axis of the connector body; the inlet pipe mounting hole penetrates the second chamber; the outlet pipe mounting hole is located on the side of the second chamber opposite to the first chamber, and the inner diameter of the outlet pipe mounting hole is larger than the outer diameter of the inlet pipe mounting hole.
[0010] Furthermore, the inner diameter of the liquid outlet pipe mounting hole is the same as the inner diameter of the second chamber.
[0011] Furthermore, the outer diameter of the end of the connector body facing away from the first chamber gradually increases from the end face toward the sealing portion, and the maximum outer diameter of the end is smaller than the outer diameter of the sealing portion.
[0012] Furthermore, a positioning boss is provided at one end of the connector body opposite to the second chamber.
[0013] Furthermore, the first chamber has an opening on the side opposite to the second chamber, and a sealing plate is sealed to the opening of the first chamber.
[0014] Furthermore, the central axis of each of the first through holes is arranged radially along the first chamber.
[0015] Furthermore, the central axis of the second through hole and the central axis of the second chamber are located in the same plane and are set at an angle.
[0016] The beneficial effects of this utility model are as follows: The rotary joint side blocking plate of this utility model can seal the end of the inner cylinder and the outer cylinder of the heat exchange roller, preventing the heat exchange medium in the heat exchange channel from flowing out; by opening the inlet pipe mounting hole and the outlet pipe mounting hole, the joint body can be connected to the inlet pipe and the outlet pipe together; in addition, by opening the first chamber and the second chamber in the joint body, and connecting the first chamber to the inlet end of the heat exchange channel through the first through hole, and connecting the second chamber to the outlet end of the heat exchange channel through the second through hole, the heat exchange medium can be smoothly entered and exited from the same end of the roller.

[0018] Figure 2 This is a perspective view of a rotary joint side blocking plate provided by this utility model. Detailed Implementation
[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 2As shown, a rotary joint side sealing plate includes a joint body 10, in which a first chamber 1 and a second chamber 2 are arranged axially at intervals; the first chamber 1 is connected to an inlet pipe mounting hole 4, and the second chamber 2 is connected to an outlet pipe mounting hole 5; a plurality of first through holes 11 and a plurality of second through holes 21 are alternately opened circumferentially on the outer periphery of the joint body 10; the first through holes 11 are connected to the first chamber 1; the second through holes 21 are connected to the second chamber 2; and a sealing part 3 is protruding circumferentially on the outer periphery of the joint body 10.
[0021] Specifically, in this embodiment, the connector body 10 is cylindrical. A positioning boss 6 protrudes from the end of the connector body 10 opposite to the second chamber 2; this positioning boss 6 allows for positioning of the inner cylinder end of the heat exchange roller. The sealing part 3 is used for a sealed connection with the inner side of the outer cylinder of the heat exchange roller. In use, the connector body 10 and the sealing part 3 can seal the space between the inner cylinder end and the outer cylinder of the heat exchange roller to prevent the heat exchange medium in the heat exchange channel from flowing out. The first through hole 11 is used to connect with the inlet end of the heat exchange channel, and the second through hole 21 is used to connect with the outlet end of the heat exchange channel.
[0022] As a preferred embodiment of this invention, the inlet pipe mounting hole 4 and the outlet pipe mounting hole 5 are coaxial, and their central axes are collinear with the central axis of the connector body 10. The inlet pipe mounting hole 4 penetrates the second chamber 2; the outlet pipe mounting hole 5 is located on the side of the second chamber 2 opposite to the first chamber 1, and the outer diameter of the outlet pipe mounting hole 5 is larger than the outer diameter of the inlet pipe mounting hole 4. In this embodiment, the inner diameter of the outlet pipe mounting hole 5 is the same as the inner diameter of the second chamber 2.
[0023] In this embodiment, the inlet pipe mounting hole 4 is used to install the inlet pipe, and the outlet pipe mounting hole 5 is used to install the outlet pipe 8 sleeved on the outside of the inlet pipe, so that the inlet pipe is connected to the first chamber 1 and the outlet pipe 8 is connected to the second chamber 2, thereby realizing that the heat exchange medium enters and exits at the same end of the roller.
[0024] In this embodiment, the outer diameter of the end of the connector body 10 facing away from the first chamber 1 gradually increases from the end face toward the sealing part 3, and the maximum outer diameter of the end is smaller than the outer diameter of the sealing part 3. This structure ensures the structural strength of the connection between the connector body 10 and the outlet pipe 8, while preventing the end of the connector body 10 facing away from the first chamber 1 from contacting the inner surface of the outer cylinder of the heat exchange roller, thus reducing assembly difficulty.
[0025] In this embodiment, the first chamber 1 has an opening on the side opposite to the second chamber 2, and a sealing plate 7 is sealed at the opening of the first chamber 1 to prevent the heat exchange medium in the first chamber 1 from flowing out from the opening.
[0026] As a preferred embodiment of the present invention, the radial cross-section of the first chamber 1 is circular; the central axis of each first through hole 11 is arranged radially along the first chamber 1, so that the heat exchange medium in the first chamber 1 can quickly flow into the heat exchange channel through the first through hole 11.
[0027] As a preferred embodiment of the present invention, the radial cross-section of the second chamber 2 is circular; the central axis of the second through hole 21 and the central axis of the second chamber 2 are located on the same plane and are set at an angle, so that the heat exchange medium in the heat exchange channel can quickly flow into the second chamber 2 through the second through hole 21.
[0028] This utility model provides a rotary joint side blocking plate that can seal the inner cylinder end and outer cylinder of the heat exchange roller, preventing the heat exchange medium in the heat exchange channel from flowing out. By opening the inlet pipe mounting hole 4 and the outlet pipe mounting hole 5, the joint body 10 can be connected to both the inlet pipe and the outlet pipe 8. By opening the first chamber 1 and the second chamber 2 in the joint body 10, and connecting the first chamber 1 and the inlet end of the heat exchange channel through the first through hole 11, and connecting the outlet end of the heat exchange channel and the second chamber 2 through the second through hole 21, the heat exchange medium can smoothly enter and exit from the same end of the roller.
