Description

Technical Field

[0001] The utility model relates to the technical field of cold water rollers, in particular to a cold water roller with uniform heat exchange. Background Technique

[0002] The cold water roller, also known as the cooling roller, is a roller through which cooling water is passed. When calendering films or adhesive tapes are coated, in order to reduce the deformation caused by the shrinkage of hot materials during cooling when the finished product is wound into a roll, the material is passed through the cooling roller before winding to cool it down to reduce the deformation of the material.

[0003] Some devices on the market generally use connecting blocks connected to the water receiving pipes to prevent the water receiving pipes from directly contacting the water-cooled rollers. During use, the rotation of the roller body does not drive the rotation of the water receiving pipes, thus avoiding the phenomenon of the water pipe being wound into the rotating shaft when the cold water roller rotates, and improving the safety of production.

[0004] However, during the actual use of the above devices, when changing the water inside the roller body, the cold water and hot water inside the roller body will be mixed together, resulting in unstable temperature inside the roller body, which makes the cold water roller unable to cool the product well. In view of this, we propose a cold water roller with uniform heat exchange. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cold water roller with uniform heat exchange to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cold water roller with uniform heat exchange, including a rotating shaft, a roller body is fixedly connected to the outer surface of the rotating shaft, a cooling structure is arranged on one side of the roller body, and the cooling structure includes:

[0007] A transmission groove, a transmission groove is opened inside the roller body, the transmission groove is arranged in a frustum shape, a cooling groove is opened inside the roller body, a water inlet hole is opened on the inner wall of the transmission groove, and a drainage part is fixedly connected to the inner wall of the cooling groove near the water inlet hole;

[0009] A dispersing part, a dispersing part is fixedly connected to the outer surface of the rotating shaft, the dispersing part is arranged in a fan shape, a flow dividing part is fixedly connected to the outer surface of the rotating shaft, and the flow dividing part is arranged in a frustum shape.

[0010] Preferably, the position of the water inlet tank corresponds to the position of the water inlet pipe, and the water inlet tank communicates with the transfer tank, which enables the water inside the water inlet pipe to enter the transfer tank through the water inlet tank.

[0011] Preferably, the position of the water outlet tank corresponds to the position of the water outlet pipe, and the water outlet tank communicates with the cooling tank, which enables the water inside the cooling tank to enter the water outlet pipe through the water outlet tank.

[0012] Preferably, the dispersing members are evenly distributed in a curve driving array on the outer surface of the rotating shaft, and the dispersing members are arranged inside the transfer tank, which enables the dispersing members to disperse the water inside the transfer tank when the rotating shaft rotates.

[0013] Preferably, a movable groove is formed at one end of the roller body, a movable member is rotatably connected inside the movable groove, a threaded rod is fixedly connected to one side of the movable member, and a nut is threadedly connected to the outer surface of the threaded rod.

[0014] Preferably, one end of the threaded rod penetrates through the seal, and the size of the movable groove is adapted to the size of the movable member.

[0015] Compared with the prior art, the present utility model provides a cold water roller with uniform heat exchange, and has the following beneficial effects:

[0016] 1. For this cold water roller with uniform heat exchange, in order to avoid non-uniform heat exchange when the equipment changes water, the water inlet pipe fills cold water into the transfer tank. At the same time, the dispersing members rotate with the rotating shaft to make the cold water rotate, and the transfer tank is arranged in a frustum shape, with its small-diameter end close to the water inlet pipe. Thus, when the cold water rotates, it fits with the inner wall of the transfer tank, which enables the hot water inside the cooling tank to be cooled first, so that the equipment can maintain a good heat exchange effect. At the same time, the cold water inside the cooling tank is transmitted out through the water outlet pipe, and the cold water inside the transfer tank enters the cooling tank through the diversion member and the water inlet holes, so that the equipment can still maintain uniform heat exchange well when changing water.

[0017] 2. For this cold water roller with uniform heat exchange, in order to prevent the water pipes from affecting the rotation of the equipment, the side of the seal close to the roller body is in contact with the movable member. The movable member is rotatably connected inside the movable groove formed at one end of the roller body, and the threaded rod arranged on one side of the movable member penetrates through one side of the seal and the seal is limited by the nut. Thus, when the equipment rotates, the movable member rotates inside the movable groove and the seal does not rotate, which enables the water inlet pipe and the water outlet pipe not to affect the rotation of the equipment.

[0025] In the embodiment of the present utility model, a transmission groove 6 is opened inside the roller body 2, the transmission groove 6 is arranged in a frustum shape, so that the cold water can be poured into the transmission groove 6 by the water inlet pipe 4, and at the same time, the dispersing member 9 rotates with the rotating shaft 1 to make the cold water rotate, and the transmission groove 6 is arranged in a frustum shape, and the small-diameter end of the transmission groove 6 is close to the water inlet pipe 4, so that when the cold water rotates, it fits with the inner wall of the transmission groove 6, which enables the hot water in the cooling groove 7 to be cooled first, so that the device can maintain a good heat exchange effect. A cooling groove 7 is opened inside the roller body 2, a water inlet hole 10 is opened on the inner wall of the transmission groove 6, and a water guiding member 11 is fixedly connected to the inner wall of the cooling groove 7 near the water inlet hole 10.

[0026] Furthermore, a water inlet groove 12 is formed at one end of the roller body 2. The position of the water inlet groove 12 corresponds to that of the water inlet pipe 4. The water inlet groove 12 communicates with the transmission groove 6, which enables the water inside the water inlet pipe 4 to enter the transmission groove 6 through the water inlet groove 12. A water outlet groove 13 is formed at one end of the roller body 2. The position of the water outlet groove 13 corresponds to that of the water outlet pipe 5. The water outlet groove 13 communicates with the cooling groove 7, which enables the water inside the cooling groove 7 to enter the water outlet pipe 5 through the water outlet groove 13. A sealing ring 14 is arranged inside the water inlet groove 12. A sealing member 3 is fixedly connected to one side of the sealing ring 14.

[0027] In the present utility model, during use, the water inlet pipe 4 fills cold water into the transmission groove 6. At the same time, the dispersing member 9 rotates together with the rotating shaft 1 to rotate the cold water. The transmission groove 6 is frustum-shaped, and the small-diameter end of the transmission groove 6 is close to the water inlet pipe 4. Thus, when the cold water rotates, it fits with the inner wall of the transmission groove 6, which enables the hot water inside the cooling groove 7 to be cooled first, enabling the device to maintain a good heat exchange effect. At the same time, the cold water inside the cooling groove 7 is transmitted out through the water outlet pipe 5. The cold water inside the transmission groove 6 passes through the flow dividing member 8 and enters the cooling groove 7 through the water inlet holes 10, so that the device can still maintain uniform heat exchange well when changing water.

[0028] Furthermore, when the device rotates, one side of the sealing member 3 close to the roller body 2 contacts the movable member 16. The movable member 16 is rotatably connected inside the movable groove 15 formed at one end of the roller body 2. A threaded rod 17 arranged on one side of the movable member 16 penetrates through one side of the sealing member 3 and the sealing member 3 is limited by using a nut 18. Thus, when the device rotates, the movable member 16 rotates inside the movable groove 15 to prevent the sealing member 3 from rotating, which enables the water inlet pipe 4 and the water outlet pipe 5 not to affect the rotation of the device.

[0029] The above text generally describes the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
