Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper production, and in particular to a corrugated roller group with a heat dissipation function. Background Art

[0002] Corrugated paper plays an important role in our daily life. Whether it is express delivery or packaging, cartons made of corrugated paper are very common. Corrugated rollers are important components for producing corrugated paper, usually including main corrugated rollers and press rollers. The main corrugated rollers cooperate with the press rollers to squeeze the base paper into a corrugated shape, and then the base paper and the face paper are glued to the corrugated base paper through the subsequent gluing process to complete the basic corrugated paper processing. The main corrugated roller needs to be heated during the pressing process, but in order to ensure the processing accuracy, the press roller needs to be kept at room temperature as much as possible to reduce deformation. However, after a long period of processing, the press roller will usually gradually heat up under the drive of the main corrugated roller, affecting the processing accuracy of the base paper. Summary of the invention

[0033] The present invention is described in detail below in conjunction with specific embodiments.

[0034] In the present invention, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it 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 invention can be understood according to the specific circumstances. The directional words that appear in the present invention are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present invention 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.

[0035] like Figures 1 to 13 As shown, the present invention provides a corrugated roller group with heat dissipation function, including a frame 1, on which a meshing corrugated roller 2 and a paper pressing roller 3 are arranged, end covers 5 are arranged at both ends of the paper pressing roller 3, and a heat dissipation component 4 is installed on the end cover 5, and the heat dissipation component 4 includes a heat dissipation motor 40 and an impeller 41; a through hole 51 is arranged in the end cover 5, and the impeller 41 is installed in the through hole 51 through a support frame 44, and the heat dissipation motor 40 is used to drive the impeller 41 to rotate; a heat dissipation cavity 38 is arranged inside the paper pressing roller 3, and the heat dissipation cavity 38 is connected with the through hole 51, and a plurality of heat dissipation fins 30 are installed in the heat dissipation cavity 38, and the end cover 5 is provided with an air outlet 50 near the heat dissipation fin 30.

[0036] Heating the corrugated roller 2 can effectively improve the processing efficiency of corrugated paper. However, since the corrugated roller 2 usually needs to be used in conjunction with the paper pressing roller 3, and the paper pressing roller 3 does not need to be heated, the temperature of the paper pressing roller 3 will gradually increase under the effect of heat transfer after long-term contact operation. Due to the thermal expansion and contraction effect, the external dimensions of the paper pressing after heating will change slightly. These slight changes may affect the accuracy of the corrugated paper. Through the above design scheme, when processing, the heat dissipation motor 40 drives the impeller 41 to rotate, and guides the outside air into the heat dissipation cavity 38 inside the paper pressing roller 3. The heat sink 30 in the heat dissipation cavity 38 can quickly conduct the heat of the paper pressing roller 3. The airflow will take away a lot of heat when passing through the heat sink 30, so that the temperature of the paper pressing roller 3 is reduced, and the airflow that takes away the heat will be blown out through the air outlet 50.

[0037] In this embodiment, the heat sink 30 includes a bonding plate 31, a vertical plate 32 and a guide plate 33. The bonding plate 31 is bonded to the inner wall of the heat dissipation cavity 38, and a plurality of groups of limit strips 37 are arranged on the inner wall of the heat dissipation cavity 38. The bonding plate 31 is provided with a slide groove 36 corresponding to the limit strips 37. The bonding plate 31 is evenly provided with a plurality of vertical plates 32, and an air duct 35 is formed between adjacent vertical plates 32, and the air duct 35 corresponds to the air outlet 50. The vertical plate 32 is provided with a guide plate 33 at the end away from the bonding plate 31, and the guide plate 33 is provided with an opening 34 on the side away from the end cover 5.

[0038] Through the above-mentioned design scheme, the bonding plate 31 is closely attached to the inner wall of the heat dissipation cavity 38 under the guidance of the limiting strip 37. In actual use, thermal conductive silicone grease can be filled between the bonding plate 31 and the inner wall of the heat dissipation cavity 38 to further improve the thermal conductivity efficiency. The vertical plate 32 on the bonding plate 31 can increase the contact area between the heat sink 30 and the airflow, thereby improving the heat dissipation efficiency and ensuring that the flowing air can take away more heat. The guide plate 33 can guide the airflow entering the heat dissipation cavity 38 from the through hole 51. Under the guidance of the guide plate 33, the airflow enters the heat dissipation cavity 38 and enters the air duct 35 through the opening 34 on the guide plate 33. When the airflow passes through the air duct 35, it can take away a large amount of heat and then blow out from the air outlet 50.

[0039] In this embodiment, the end cover 5 is connected to the frame 1 through a sliding frame 11 . The sliding frame 11 can slide on the frame 1 , and a bearing 10 is installed between the sliding frame 11 and the end cover 5 .

[0040] In this embodiment, a limiting groove 12 is provided on the frame 1, a protrusion 16 is provided on the sliding frame 11, and the protrusion 16 can slide in the limiting groove 12. An adjusting screw 14 is also provided above the sliding frame 11, and the adjusting screw 14 is used to control the sliding of the sliding frame 11 on the frame 1, thereby controlling the paper pressing roller 3 to approach or move away from the corrugated roller 2; a limiting elastic member 15 is sleeved on the adjusting screw 14, and one end of the limiting elastic member 15 is against the sliding frame 11, and the other end is against the frame 1.

[0041] Through the above design, the user can control the distance between the paper pressing roller 3 and the corrugating roller 2 by rotating the adjusting screw 14, and control the processing efficiency of the corrugated paper by changing the distance between the two.

[0042] In this embodiment, a mounting frame 13 is provided on the sliding frame 11, and the heat dissipation motor 40 is installed on the mounting frame 13; a rotating shaft 43 is provided on the end cover 5, and the rotating shaft 43 is installed in the through hole 51 through a supporting frame 44, and the rotating shaft 43 is fixedly connected to the rotor of the heat dissipation motor 40, and at least one set of impellers 41 is fixedly installed on the rotating shaft 43.

[0043] In this embodiment, two heat dissipation cavities 38 are provided in the paper pressing roller 3. The two heat dissipation cavities 38 are not communicated with each other, and six groups of heat dissipation fins 30 are installed in each heat dissipation cavity 38; the two heat dissipation cavities 38 are respectively communicated with the through holes 51 in the two groups of end covers 5.

[0044] In this embodiment, a plurality of groups of blades 42 are evenly distributed on the impeller 41 .

[0045] In this embodiment, the heat sink 30 is made of a metal material with high thermal conductivity, such as copper, aluminum, etc. The metal material with high thermal conductivity can ensure that the temperature of the paper pressing roller 3 can be quickly transferred to the heat sink 30, thereby improving the heat dissipation efficiency.

[0046] Compared with the prior art, the present invention provides a corrugated roller group with a heat dissipation function. The heat dissipation motor 40 can drive the impeller 41 to rotate to guide the outside air into the through hole 51. The outside air enters the heat dissipation cavity 38 through the through hole 51, enters the air duct 35 through the opening 34, and finally blows out from the air outlet 50. When the airflow passes through the air duct 35, it can effectively take away the heat conducted by the vertical plate 32, thereby ensuring that the paper pressing roller 3 can be maintained at a normal temperature and preventing the deformation of the paper pressing roller 3 from affecting the processing accuracy.

[0047] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
