Description

Technical Field

[0001] The utility model belongs to the technical field of functional roller devices, and particularly relates to a cooling device for a glue roller. Background Art

[0002] Sizing rollers are often used in coating, laminating and other processes. For example, when applying a functional coating on the surface of paper, in order to quickly cool and shape the coating, the sizing roller often needs to be used in conjunction with a cooling device.

[0003] The existing utility model patent with application number 202321613832 discloses a glue roller cooling device, which conducts heat from the surface of the glue roller through heat dissipation fins and injects coolant through the inlet and outlet holes to take away the heat.

[0004] The above device has the following defects: it needs to continuously supply coolant for cooling the glue roller, which consumes a large amount of coolant. If the coolant is cooled and recovered, it needs to consume a lot of electricity; the efficiency of heat conduction through the cooling fins is low, and the heat dissipation effect is poor. Utility Model Content

[0005] The purpose of the present invention is to solve the problem of large resource consumption and poor heat dissipation effect of the glue roller cooling device described in the above background technology. A new glue roller cooling device is proposed here, which has good heat dissipation effect and consumes less resources.

[0006] A technical solution adopted to achieve the above purpose is a sizing roller cooling device, the cooling device comprising:

[0007] A glue roller body, wherein an annular cavity is provided in the glue roller body, and a through hole is provided on one side of the rotating shaft of the glue roller body, and the through hole is connected to the annular cavity;

[0008] A cooling pipe, wherein the cooling pipe is arranged in the annular cavity and the through hole;

[0009] A connecting piece connected to the cooling pipe;

[0010] A circulation pump is connected to the connecting piece through a pipeline.

[0011] Furthermore, the connecting part includes a shell, a connecting pipe and a connecting ring, a first inlet and an annular slide rail are provided on one side of the shell, a first outlet and a second outlet are provided on the other side of the shell, the connecting pipe is arranged inside the shell, the connecting pipe connects the first inlet and the first outlet, the connecting ring is slidably fitted with the annular slide rail, and a second inlet is provided on the connecting ring.

[0012] In the above technical solution, the cooling pipe is used to transport the cooling liquid. The cooling pipe is arranged on the surface of the glue roller body and can exchange heat with the surface of the glue roller to the greatest extent, thereby achieving a good cooling effect.

[0013] Furthermore, one end of the cooling pipe is rotatably connected to the first inlet, and the other end of the cooling pipe is detachably connected to the second inlet.

[0014] In the above technical solution, one end of the cooling pipe is located on the center line of the glue roller body and is connected to the first inlet for transporting the coolant, and the other end is transported through the connecting ring for transporting the coolant. Compared with transporting the coolant from both ends of the glue roller, the device footprint is reduced, which is conducive to saving space.

[0015] Furthermore, the first outlet is connected to the water inlet of the circulation pump through a pipeline, and the second outlet is connected to the water outlet of the circulation pump through a pipeline.

[0016] Furthermore, the glue roller cooling device also includes a cooling device, the first outlet is connected to the water inlet of the circulation pump through a pipeline, the water outlet of the circulation pump is connected to the water inlet of the cooling device through a pipeline, and the water outlet of the cooling device is connected to the second outlet through a pipeline.

[0017] In the above technical solution, the coolant can be cooled by the cooling device and recycled.

[0018] Furthermore, a plurality of spherical microcapsules are provided in the cooling tube, and the interior of the spherical microcapsules is hollow.

[0019] Furthermore, the spherical microcapsules are filled with phase change materials.

[0020] In the above technical solution, by filling the cooling tube with phase change material, the surface of the glue roller is driven by the coolant to absorb heat, and at the same time, the heat is released to the air during the rotation of the glue roller body. At this time, the cooling tube and the circulation pump can form a loop, and there is no need to set up a cooling device, which greatly reduces energy consumption.

[0021] Furthermore, the cooling pipe located in the annular cavity is arranged in a wave shape.

[0022] In the above technical solution, the wave-shaped cooling pipe is provided to increase the contact area between the cooling pipe and the surface of the sizing roller body, thereby enhancing the cooling effect.

[0023] Furthermore, the glue roller cooling device also includes a motor, and the output end of the motor is connected to the rotating shaft on the other side of the glue roller body through a belt transmission.

[0024] The advantages of the present invention are:

[0025] 1. The utility model directly arranges the cooling pipe on the surface of the sizing roller body, which greatly increases the contact area and has a better cooling effect.

[0026] 2. The utility model forms a circulation loop of the cooling pipe and the circulation pump by arranging microcapsules filled with phase change material in the cooling pipe. There is no need to constantly introduce coolant or cool the coolant for recovery, which greatly reduces resource consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The cooling pipe is arranged in the annular cavity and the through hole. The inlet of the cooling pipe enters the interior of the sizing roller body from the through hole, then enters the annular cavity for winding, and then passes through the through hole. The through hole is in the shape of an "8", and one mouth of the through hole is located at the center of the rotating shaft.

[0038] like Figure 4 As shown, the connecting piece consists of a shell 301, a connecting pipe 302 and a connecting ring 303. A first inlet 304 is provided at the center of the left side of the shell, and an annular slide rail 305 is provided with the center of the left side as the center of the circle. A first outlet 306 and a second outlet 307 are provided on the right side of the shell. The connecting pipe is arranged inside the shell, and the connecting pipe connects the first inlet and the first outlet. The connecting ring slides with the annular slide rail, and a second outlet 308 is provided on the connecting ring.

[0039] The first outlet is connected to the water inlet of the circulation pump through a pipeline, the second outlet is connected to the water outlet of the circulation pump through a pipeline, one end of the cooling pipe is rotatably connected to the first inlet, and the other end of the cooling pipe is detachably connected to the second inlet.

[0040] A number of spherical microcapsules are arranged in the cooling tube. The interior of the spherical microcapsules is hollow and filled with phase change material. The phase change material can be selected from acetate trihydrate or sodium sulfate decahydrate, etc. The specific type can be selected according to the type of sizing.

[0041] like Figure 3 As shown, in this embodiment, the cooling pipe located in the annular cavity is arranged in a wave shape.

[0042] In this embodiment, the output end of the motor and the rotating shaft portion on the other side of the glue roller body are driven by a belt.

[0043] Example 2

[0044] like Figure 2 As shown, the structure of the glue roller cooling device is the same as that of Example 1, except that the glue roller cooling device is further provided with a cooling device, the first outlet of which is connected to the water inlet of the circulation pump through a pipeline, the water outlet of the circulation pump is connected to the water inlet of the cooling device through a pipeline, the water outlet of the cooling device is connected to the second outlet through a pipeline, and the cooling pipe, the circulation pump and the cooling device form a circulation loop.

[0045] The working principle of this utility model:

[0046] Cooling liquid and spherical microcapsules are introduced into the cooling tube, and the cooling liquid is circulated in the cooling tube by a circulating pump. When the glue roller rotates, the external glue coating mechanism contacts part of the surface of the glue roller to perform the gluing operation. At this time, the phase change material in the spherical microcapsules in the contact part of the glue roller and the glue coating mechanism undergoes phase change and absorbs heat, and disperses the heat through the cooling liquid and circulating flow. The spherical microcapsules in the part not in contact with the glue roller and the glue coating mechanism release heat for dissipation.
