Description

Technical Field

[0001] The utility model relates to the technical field of cold water rollers, and specifically relates to a double-layer cold water roller facilitating heat dissipation. Background Art

[0002] A cold water roller is a roller device used in the calendering of films or the coating of adhesive tapes. Its function is to reduce the temperature of materials by introducing cooling water, thereby reducing the deformation caused by the shrinkage of hot materials during cooling. The role of the cold water roller is to reduce the temperature of the materials through the cooling process before the materials are wound into rolls, so as to achieve the purpose of reducing material deformation. This device is widely used in various applications to help improve the quality and performance of products.

[0003] According to a disclosed highly efficient heat dissipation double-layer cold water roller (publication number: CN217764066U), in the above application, the water roller includes an outer sleeve. A cavity is provided inside the outer sleeve, and a rotary condenser tube is provided to replace the traditional cavity structure. This design enables the cold water roller to be cooled and cooled comprehensively when rotating. Compared with the traditional cavity structure that can only cool half of the part, the cooling efficiency is greatly improved. In addition, the cold water roller also has a user-friendly design, and a temperature warning component is provided to monitor the temperature of the cold water roller.

[0004] However, in the actual use process of the above cold water roller, due to the low heat conduction property of air, when the outer sleeve rotates, the condenser tube cannot effectively come into close contact with the surface of the roller, resulting in low heat conduction efficiency. This gap limits the direct heat exchange between the cooling water and the roller, thereby reducing the cooling effect. In view of this, we propose a double-layer cold water roller facilitating heat dissipation. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double-layer cold water roller facilitating heat dissipation to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A double-layer cold water roller facilitating heat dissipation, including an outer sleeve, wherein a cooling component is arranged on the inner wall of the outer sleeve, and the cooling component includes:

[0007] A water retaining ring, the outer sleeve is in threaded connection with a limiting sleeve, and the limiting sleeve is sleeved with the water retaining ring;

[0008] A mounting seat, the limiting sleeve is sleeved with the mounting seat, the outer wall of the mounting seat abuts against the water retaining ring, the mounting seat is sleeved with a water inlet pipe, the water inlet pipe is fixedly connected with a heat exchange pipe, one end of the heat exchange pipe away from the water inlet pipe is fixedly connected with a water outlet pipe, and the water outlet pipe is sleeved with the mounting seat;

[0009] The spoiler, a connecting rod is fixedly connected to the inner wall of the outer sleeve, and one end of the connecting rod away from the outer sleeve is fixedly connected to the spoiler. A guiding strip is fixedly connected to the surface of the spoiler.

[0010] Preferably, a convex ring is fixedly connected to the inner wall of the outer sleeve.

[0011] Preferably, an arc-shaped groove is formed on the surface of the mounting seat, and the arc-shaped groove is sleeved with a water retaining ring. The water retaining ring has a certain elasticity. When the water retaining ring is worn, the water retaining ring is elastically deformed to push it further against the mounting seat, thereby preventing water leakage from the gap between the outer sleeve and the mounting seat.

[0012] Preferably, the guiding strip is arranged obliquely on the surface of the spoiler, enabling the coolant to flow horizontally and improving the uniform distribution of the coolant.

[0013] Preferably, a plurality of groups of spoilers are provided, and the plurality of groups of spoilers are arranged in a circumferential manner at equal intervals inside the outer sleeve.

[0015] Compared with the prior art, the present utility model provides a double-layer cold water roll that is convenient for heat dissipation, and has the following beneficial effects:

[0016] 1. For this double-layer cold water roll that is convenient for heat dissipation, through the heat exchange tube, spoiler, and guiding strip provided, the coolant and water can conduct heat directly, improving the heat exchange efficiency. The outer sleeve rotates under the action of an external driving device, thereby driving the spoiler to rotate. Due to the different surface areas of the upper and lower sides of the spoiler, the flow rates of the coolant on the upper and lower sides of the spoiler are different, forming a pressure difference, thereby promoting the circulation of the coolant, that is, the coolant at a lower temperature near the heat exchange tube flows to the vicinity of the inner wall of the outer sleeve, thereby promoting the heat exchange efficiency. The guiding strip is arranged obliquely on the surface of the spoiler, enabling the coolant to flow horizontally, improving the uniform distribution of the coolant, and further improving the heat exchange efficiency. At the same time, by rotating the limit sleeve, the water retaining ring can be replaced, extending the service life of the cold water roll.

[0017] 2. For this double-layer cold water roll that is convenient for heat dissipation, through the convex ring provided, the contact area between the outer sleeve and the coolant is increased, improving the heat conduction efficiency between the coolant and the outer sleeve, enabling the coolant to more effectively absorb the heat inside the outer sleeve, preventing the outer sleeve from overheating, maintaining a suitable working temperature on the surface of the roll, and thus improving the heat dissipation efficiency and working performance of the cold water roll.

[0023] As Figures 1-4 shown, the present utility model provides a technical solution: a double-layer cold water roller facilitating heat dissipation, including an outer sleeve 1, and a cooling assembly is arranged on the inner wall of the outer sleeve 1. The cooling assembly includes a limiting sleeve 2, a water blocking ring 3, a mounting seat 4, a water inlet pipe 5, a heat exchange pipe 6, a water outlet pipe 7, a connecting rod 8, a spoiler 9, a flow guiding strip 10, and a convex ring 11.

[0024] In an embodiment of the present utility model, the outer sleeve 1 is threadedly connected to the limiting sleeve 2, the limiting sleeve 2 is sleeved with the water blocking ring 3, a mounting seat 4 is sleeved inside the limiting sleeve 2, the outer wall of the mounting seat 4 abuts against the water blocking ring 3, an arc-shaped groove is formed on the surface of the mounting seat 4, the arc-shaped groove is sleeved with the water blocking ring 3, and the water blocking ring 3 has a certain elasticity. When the water blocking ring 3 is worn, the water blocking ring 3 pushes itself further against the mounting seat 4 through elastic deformation, thereby avoiding water leakage from the gap between the outer sleeve 1 and the mounting seat 4. The mounting seat 4 is sleeved with the water inlet pipe 5, the water inlet pipe 5 is fixedly connected to the heat exchange pipe 6, the end of the heat exchange pipe 6 far from the water inlet pipe 5 is fixedly connected to the water outlet pipe 7, the water outlet pipe 7 is sleeved with the mounting seat 4, a connecting rod 8 is fixedly connected to the inner wall of the outer sleeve 1, one end of the connecting rod 8 far from the outer sleeve 1 is fixedly connected to the spoiler 9, the number of the spoilers 9 is provided with several groups, and several groups of spoilers 9 are arranged in an equidistant circular arrangement inside the outer sleeve 1. The spoiler 9 is not in contact with the heat exchange pipe 6, and the heat exchange pipe 6 is spirally wound around the inner wall of the outer sleeve 1, thereby improving the heat exchange efficiency. The surface of the spoiler 9 is fixedly connected with a flow guiding strip 10, and the flow guiding strip 10 is arranged obliquely on the surface of the spoiler 9, enabling the coolant to flow horizontally and improving the uniform distribution of the coolant. A convex ring 11 is fixedly connected to the inner wall of the outer sleeve 1.

[0025] The outer surface material of the outer sleeve 1 comes into contact, and the material transfers heat through the outer sleeve 1 into the coolant stored inside the outer sleeve 1. Cold water enters the heat exchange tube 6 through the water inlet pipe 5. The cold water in the heat exchange tube 6 absorbs the heat of the coolant and is discharged through the water outlet pipe 7. The coolant and water can conduct heat directly, improving the efficiency of heat exchange. The outer sleeve 1 rotates under the action of an external driving device, thereby driving the spoiler 9 to rotate. Due to the different surface areas of the upper and lower sides of the spoiler 9, the flow rates of the coolant on the upper and lower sides of the spoiler 9 are different, forming a pressure difference, which further promotes the circulation of the coolant. That is, the coolant at a lower temperature near the heat exchange tube 6 flows towards the inner wall of the outer sleeve 1, thereby promoting the heat exchange efficiency. The guide strip 10 is inclined on the surface of the spoiler 9, enabling the coolant to flow laterally, improving the uniform distribution of the coolant, and further improving the heat exchange efficiency.

[0026] In addition, a convex ring 11 is fixedly connected to the inner wall of the outer sleeve 1. The setting of the convex ring 11 increases the contact area between the outer sleeve 1 and the coolant, improving the heat conduction efficiency between the coolant and the outer sleeve 1, enabling the coolant to more effectively absorb the heat inside the outer sleeve 1, preventing the outer sleeve 1 from overheating, maintaining a suitable working temperature on the surface of the roller, and thus improving the heat dissipation efficiency and working performance of the cold water roller.

[0027] In the present utility model, during use, the outer surface material of the outer sleeve 1 comes into contact, and the material transfers heat through the outer sleeve 1 into the coolant stored inside the outer sleeve 1. Cold water enters the heat exchange tube 6 through the water inlet pipe 5. The cold water in the heat exchange tube 6 absorbs the heat of the coolant and is discharged through the water outlet pipe 7. The coolant and water can conduct heat directly. The outer sleeve 1 rotates under the action of an external driving device, thereby driving the spoiler 9 to rotate. Due to the setting of the spoiler 9, the sizes of the spaces below and above the spoiler 9 in the inner cavity of the outer sleeve 1 are different, so that the flow rates of the coolant on the upper and lower sides of the spoiler 9 are different, forming a pressure difference, which further promotes the circulation of the coolant. The guide strip 10 is inclined on the surface of the spoiler 9, enabling the coolant to flow laterally, improving the uniform distribution of the coolant. Further, the setting of the convex ring 11 increases the contact area between the outer sleeve 1 and the coolant, improving the heat conduction efficiency between the coolant and the outer sleeve 1, enabling the coolant to more effectively absorb the heat inside the outer sleeve 1.

[0028] The above has generally described 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 art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
