Description

Technical Field

[0001] This utility model relates to the field of cooling roller technology, specifically a cooling roller for circulating cooling water. Background Technology

[0002] Cooling rollers are rollers through which cooling water is introduced. When coating calendered films or adhesive tapes, in order to reduce deformation caused by shrinkage during the cooling process, the material is passed through cooling rollers before winding to reduce deformation. In existing cooling rollers, the coolant typically enters from one side, circulates through a single-flow heat-conducting pipe, and flows out from the other side. Because the coolant first contacts one end of the cooling roller and then exits from the other end, the temperature at one end of the cooling roller is lower than that at the other end, resulting in low uniformity of cooling temperature. Utility Model Content

[0003] The purpose of this invention is to provide a cooling roller for circulating cooling water to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A cooling roller for circulating cooling water includes a cooling roller body. One end of the cooling roller body is fixedly connected to an end pipe. An annular pipe is fixedly connected to the inner wall of the cooling roller body. Multiple dispersion tubes 1 and multiple dispersion tubes 2 are arranged circumferentially and equidistantly within the annular pipe. The dispersion tubes 1 and 2 are arranged opposite to each other and are staggered. One end of each dispersion tube 1 and dispersion tube 2 is embedded in and passes through the annular pipe. One end of the end pipe is provided with a connector. A liquid inlet pipe is provided inside the cooling roller body. One end of the liquid inlet pipe is fixedly connected to the connector. The other end of the liquid inlet pipe is fixedly connected to a collecting ring. A through hole 2 is opened at the other end of the liquid inlet pipe. The other ends of both dispersion tubes 1 and dispersion tubes 2 are fixedly connected to the collecting ring.

[0006] Furthermore, both ends of the cooling roller body are provided with support seats, and the other end of the cooling roller body is fixedly connected to a support shaft. The end tube and the support shaft are rotatably sleeved with the top end of the adjacent support seat.

[0007] Furthermore, the end tube has an outward protrusion at the middle position, and the inner wall of the outward protrusion has a through hole. The outer wall of the end tube is rotatably connected to the outward protrusion, and one side of the outward valve is fixedly connected to the adjacent support.

[0008] Furthermore, a sealing plate 1 is fixedly connected to the inner wall of one end of the ring pipe, and a sealing plate 2 is fixedly connected to the inner wall of the other end of the ring pipe. One end of the sealing plate 2 is fixedly connected to the inner wall of the other end of the cooling roller body. An end cavity 1 is provided between the sealing plate 2 and the other end of the cooling roller body, and an end cavity 2 is provided between the sealing plate 1 and one end of the cooling roller body.

[0009] Furthermore, multiple outlet tubes are fixedly connected in an annular shape at equal intervals between the first and second sealing plates, and the two ends of the outlet tubes are respectively connected to the first end cavity and the second end cavity.

[0010] Furthermore, both ends of the outer side wall of the cooling roller are fixedly fitted with protruding rings.

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-5 In this embodiment of the present invention, a cooling roller for circulating cooling water includes a cooling roller body 100. One end of the cooling roller body 100 is fixedly connected to an end pipe 120. An annular pipe 200 is fixedly connected to the inner wall of the cooling roller body 100. Multiple dispersion pipes 250 and multiple dispersion pipes 260 are equidistantly arranged in annular pattern within the annular pipe 200. The dispersion pipes 250 and 260 are arranged opposite to each other, and are staggered. One end of each dispersion pipe is embedded in and passes through the annular pipe 200. A connector 123 is provided at one end of the end pipe 120. An inlet pipe 230 is provided inside the cooling roller body 100. One end of the inlet pipe 230 is fixedly connected to the connector 123, and the other end of the inlet pipe 230 is fixedly connected to a collection point. The ring 240 and the liquid inlet pipe 230 have a through hole 231 at the other end. The other ends of the dispersion pipe 1 250 and the dispersion pipe 260 are fixedly connected to the collecting ring 240. A sealing plate 1 210 is fixedly connected to the inner wall of one end of the ring pipe 200. A sealing plate 220 is fixedly connected to the inner wall of the other end of the ring pipe 200. One end of the sealing plate 220 is fixedly connected to the inner wall of the other end of the cooling roller body 100. An end cavity 170 is provided between the sealing plate 220 and the other end of the cooling roller body 100. An end cavity 280 is provided between the sealing plate 1 210 and the cooling roller body 100. Multiple outlet pipes 270 are fixedly connected in an annular shape at equal intervals between the sealing plate 1 210 and the sealing plate 220. The two ends of the outlet pipes 270 are connected to the end cavity 170 and the end cavity 280, respectively.

[0022] Specifically, during use, coolant is input through inlet pipe 230, allowing it to enter the collecting ring 240. When the cooling roller body 100 rotates, it drives the ring pipe 200 to rotate synchronously. Under the action of hydraulic and centrifugal forces, the coolant in the collecting ring 240 enters the first dispersion pipe 250 and the second dispersion pipe 260. Through the staggered arrangement of the first dispersion pipe 250 and the second dispersion pipe 260, and their relative arrangement, some coolant passes through the first dispersion pipe 250 into the second end cavity 180, and some coolant passes through the second dispersion pipe 260 into the end cavity 180. Inside cavity 170, the coolant cools the annular pipe 200 as it passes through dispersion pipe 250 and dispersion pipe 260. The annular pipe 200 cools the cooling roller body 100, thus cooling the outer wall of the cooling roller body 100. Since the coolant passes through the annular pipe 200 from one end to the other, the cooling degree at one end of the annular pipe 200 is higher than that at the other end, resulting in a large temperature difference between the two ends of the annular pipe 200. Therefore, through the relative and staggered arrangement of dispersion pipe 250 and dispersion pipe 260, the cooling degree at both ends of the outer wall of the cooling roller body 100 is more uniform.

[0023] Example 1

[0024] like Figures 3-5 As shown, in this embodiment, both ends of the cooling roller body 100 are provided with support seats 160, and the other end of the cooling roller body 100 is fixedly connected to a support shaft 130. The end tube 120 and the support shaft 130 are rotatably sleeved with the top end of the adjacent support seat 160. The middle position of the end tube 120 is provided with an outward protrusion 121. The inner wall of the outward protrusion 121 is provided with a through hole 122. The outer side wall of the end tube 120 is rotatably connected to the position of the outward protrusion 121. One side of the outward protrusion 150 is fixedly connected to the adjacent support seat 160. Both ends of the outer side wall of the cooling roller body 100 are fixedly sleeved with convex rings 140. The distance between the two convex rings 140 is the same as the length of the ring tube 200.

[0025] In this embodiment, after the coolant enters the first end cavity 170, it enters the second end cavity 180 through the outlet pipe 270. Then, the coolant enters between the end pipe 120 and the inlet pipe 230 and is discharged outward from the outlet valve 150. The working area of ​​the outer wall of the cooling roller body 100 is restricted by the setting of the convex ring 140, so that the working area of ​​the outer wall of the cooling roller body 100 coincides with the contact area of ​​the ring pipe 200.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
