[0002] Corrugated paper plays a vital role in our lives today. Whether used for express delivery or packaging, cartons made from corrugated paper are extremely common. Corrugating rollers are key components in corrugated paper production and typically consist of a main corrugating roller and a press roller. These rollers work together to squeeze the paper into shape. During corrugated paper processing, the main corrugating rollers typically need to be heated to a certain temperature. High temperatures can easily cause slight deformation of the main corrugating rollers, affecting the accuracy of the corrugated paper. To maximize accuracy, the press rollers are kept at room temperature. However, after prolonged processing, the temperature of the press rollers can slowly rise due to the influence of the main corrugating rollers or the corrugated paper, further reducing the accuracy of the produced corrugated paper.

[0021] The present invention will be described in detail below with reference to specific embodiments.

[0022] In the present utility model, unless otherwise expressly provided and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are for the purpose of better explaining the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0023] like Figures 1 to 9 As shown, the utility model provides a high specific heat capacity press roller, including a press roller body 1, a cavity 2 is provided inside the press roller body 1, and a high specific heat capacity liquid is filled in the cavity 2. Heat dissipation plates 3 are evenly installed in the cavity 2, and the side walls of the heat dissipation plates 3 are in contact with the inner walls of the cavity 2. A plurality of heat dissipation fins 30 are provided on the heat dissipation plates 3; end covers 6 are provided at both ends of the press roller body 1, and a sealing gasket 5 is provided between the end cover 6 and the press roller body 1; a plurality of groups of mounting plates 4 are evenly provided on the press roller body 1, and a plurality of groups of heat pipes 40 are evenly provided on the mounting plates 4.

[0024] In this embodiment, the high specific heat capacity liquid filled in the cavity 2 is a coolant, and the heat sink 3 and the heat sink fins 30 can be made of copper or aluminum.

[0025] Through the above design, when the paper pressing roller cooperates with the corrugating roller to perform extrusion molding, the temperature of the area where the paper pressing roller body 1 meets the corrugating roller gradually increases. The heat sink 3 made of copper or aluminum can improve the heat transfer efficiency of the paper pressing roller body 1, allowing the temperature of the paper pressing roller body 1 to be quickly transferred to the cavity 2. The heat sink 30 on the heat sink 3 can effectively increase the contact area with the coolant. Heat is transferred from the contact area between the paper pressing roller body 1 and the corrugating roller to the heat sink 3, and then transferred to the coolant through the heat sink 30. The coolant has a large specific heat capacity, and more energy is required to raise the temperature to a certain level. This is used to control the temperature of the paper pressing roller body 1 and extend the time required for the paper pressing roller body 1 to heat up.

[0026] The heat pipe 40 accelerates temperature transfer, quickly transferring the temperature of the contact area to the entire platen roller body 1, maintaining a consistent temperature throughout the entire platen roller body 1 and preventing a rapid increase in temperature at the contact area between the platen roller body 1 and the high-temperature corrugating roller during a temporary shutdown. Because the heat pipe 40 is conventional technology, it is not described in detail in this embodiment.

[0027] In this embodiment, 10 groups of mounting seats 10 are provided on the inner wall of the cavity 2, and a group of heat sinks 3 are installed on each group of mounting seats 10; limiting rails 11 are provided on both sides of the mounting seats 10, and limiting grooves 31 that fit the limiting rails 11 are provided on the heat sink 3.

[0028] With the above-mentioned design, when installing the heat sink 3, the worker only needs to align the limiting groove 31 with the limiting rail 11, and then slowly push the heat sink 3 into the mounting seat 10, so that the heat sink 3 is close to the inner wall of the cavity 2 of the paper pressing roller body 1 to ensure that heat can be transferred from the paper pressing roller body 1 to the heat sink 3.

[0029] In this embodiment, three groups of mounting plates 4 are evenly arranged in the paper pressing roller body 1. The number of heat pipes 40 on the mounting plates 4 is proportional to the length of the paper pressing roller body 1. The number of heat pipes 40 increases by one for every 100 mm increase in the length of the paper pressing roller body 1.

[0030] In this embodiment, a plurality of through holes are evenly arranged on the paper pressing roller body 1 , the end cover 6 and the sealing gasket 5 , and locking rods 7 are installed in the through holes.

[0031] With the above design, when assembly is required, the user needs to install the heat pipe 40 in the mounting plate 4, then install the mounting plate 4 with the heat pipe 40 into the paper pressing roller body 1, then install the heat sink 3 in the cavity 2, and then sequentially install the sealing gasket 5 and end cap 6 on one end. When adding coolant, the user only needs to stand up the paper pressing roller body 1 with the end with the end cap 6 facing downward, wait until the cavity 2 is filled with coolant, and then sequentially install the sealing gasket 5 and end cap 6 on top to seal the coolant in the cavity 2. The sealing gasket 5 can prevent coolant leakage. When installing the end cap 6, the user can first use the locking rod 7 in conjunction with the nut to secure it, and then use welding or other methods to completely fix the end cap 6 to the paper pressing roller body 1.

[0032] In this embodiment, at least ten heat sinks 30 are evenly mounted on each set of heat sink plates 3 , and the extension lines of each set of heat sinks 30 pass through the axis of the paper pressing roller body 1 .

[0033] In this embodiment, 15 heat sinks 30 are provided on the heat sink 3 , which improves the heat transfer efficiency and prevents the heat sink 30 on the heat sink 3 from being overcrowded and affecting the heat transfer efficiency.

[0034] The utility model provides a high specific heat capacity press roller. Compared with the prior art, the high specific heat capacity liquid filled in the cavity 2 can improve the heat-bearing capacity and prolong the time for the temperature of the press roller to rise. The heat pipe 40 on the press roller body 1 can accelerate the speed of heat transfer and avoid the temperature at the junction of the press roller body 1 and the corrugated roller being too high to affect the accuracy.

[0035] In the absence of conflict, the above embodiments and features therein may be combined with each other.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
