Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production and processing, in particular to a corrugated paper base paper heating device. Background Art

[0002] Corrugated cardboard is widely used today due to its structural strength and light weight. It typically has three, five, or seven layers. Three-layer corrugated cardboard contains one layer of corrugated paper and two layers of face paper. Five-layer corrugated cardboard contains two layers of corrugated paper, two layers of face paper, and a layer of core paper between the two layers. Seven-layer corrugated cardboard contains three layers of corrugated paper, two layers of face paper, and two layers of core paper. Whether it's corrugated paper, face paper, or core paper, the raw material can be called base paper. To facilitate subsequent processing, the base paper usually undergoes a preheating process. Current corrugated cardboard processing equipment typically uses rollers with heating functions to heat the base paper. Due to the path the base paper travels, the area of ​​contact between the roller and the base paper typically only occupies 50% to 80% of the roller surface, while heat from areas not in contact with the base paper is wasted.

[0041] The present invention will be described in detail below with reference to specific embodiments.

[0042] 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.

[0043] like Figures 1 to 15 As shown, the utility model provides a corrugated paper heating device, including a heating plate 1, with bridge frames 2 installed at both ends of the heating plate 1, and guide rollers provided on the bridge frames 2; the bottom of the heating plate 1 is an arc surface 10, and multiple groups of pipes 11 are evenly arranged near the arc surface 10, and adjacent pipes 11 are connected to each other. An insulation board 12 is also provided on the side of the heating plate 1 away from the arc surface 10.

[0044] In this embodiment, the heat insulation board 12 is in an arc shape, the center of the arc coincides with the center of the arc formed by the axes of the multiple groups of pipes 11 , and arc-shaped heat conducting parts are provided at both ends of the heat insulation board 12 .

[0045] Through the above design scheme, the pipe 11 can allow high-temperature steam to flow, and the heat carried by the high-temperature steam will be transferred to the heating plate 1. After the heating plate 1 is heated by the high-temperature steam, the temperature of the heating plate 1 will increase. Under the obstruction of the insulation plate 12, the heat of the heating plate 1 will be concentrated on the arc surface 10 to prevent the heat from dissipating everywhere, thereby improving the utilization rate of heat.

[0046] The arc-shaped insulation board 12 ensures a consistent distance from the pipe 11, preventing localized overheating. The heat-conducting sections at both ends guide heat away from the edges, limiting its escape from the arc surface 10. When preheating the base paper, the paper can be placed against the arc surface 10 under the guidance of guide rollers. Because the guide rollers allow the paper to completely adhere to the arc surface 10, the contact area between the two can reach over 95%, effectively improving heat utilization.

[0047] In this embodiment, the heat insulation board 12 may be made of heat insulation cotton or heat insulation foam.

[0048] In this embodiment, the guide rollers include a front roller 3 and a rear roller 4 , and the front roller 3 and the rear roller 4 are respectively installed at two ends of the bridge frame 2 .

[0049] In this embodiment, the front roller 3 is connected to the bridge frame 2 through the front adjustment frame 5. A main threaded hole 20 and an adjustment threaded hole 21 are provided on the bridge frame 2 near the front roller 3. The front adjustment frame 5 is provided with a fixing hole 80 corresponding to the main threaded hole 20, and the front adjustment frame 5 is provided with an adjustment groove 81 corresponding to the adjustment threaded hole 21; an adjustment block 7 is provided on the front adjustment frame 5, and the adjustment block 7 is fixedly connected to the front adjustment frame 5, and an adjustment screw 8 is provided on the adjustment block 7 corresponding to the bridge frame 2.

[0050] In this embodiment, the rear roller 4 is connected to the bridge frame 2 through the rear adjustment frame 6. The rear adjustment frame 6 is L-shaped. A main threaded hole 20 and an adjustment threaded hole 21 are provided on the bridge frame 2 near the rear roller 4. The rear adjustment frame 6 is provided with a fixing hole 80 corresponding to the main threaded hole 20, and the rear adjustment frame 6 is provided with an adjustment groove 81 corresponding to the adjustment threaded hole 21; an adjustment block 7 is provided on the rear adjustment frame 6, and the adjustment block 7 is fixedly connected to the rear adjustment frame 6. The adjustment block 7 is provided with an adjustment screw 8 corresponding to the bridge frame 2.

[0051] According to the above design, when preheating is required, the base paper must first pass through the front roller 3 and then reach the arc surface 10 of the heating plate 1, and then be guided by the rear roller 4 to the next process; the front roller 3 and the rear roller 4 can both be fine-tuned by the corresponding front adjustment frame 5 or rear adjustment frame 6. When fine-tuning the front roller 3 is required, the user can first loosen the screws on the main threaded hole 20 and the adjustment threaded hole 21, so that the front adjustment frame 5 or the rear adjustment frame 6 can rotate with the main threaded hole 20 as the center of the circle. After reaching the required angle, tighten the screws on the main threaded hole 20 and the adjustment threaded hole 21 to perform preliminary locking. Then, turn the adjustment screw 8 so that the adjustment screw 8 is against the bridge frame 2 to further lock the front roller 3. The fine-tuning method of the rear roller 4 is the same as that of the front roller 3.

[0052] In this embodiment, cover plates 9 are provided at both ends of the heating plate 1 .

[0053] In the first embodiment, two groups of adapter interfaces 90 are provided on the cover plate 9 on one side of the heating plate 1 . The number of pipes 11 in the heating plate 1 is plural and two adjacent groups of pipes 11 are connected end to end.

[0054] High-temperature steam enters from one set of adapter interfaces 90 , flows through multiple sets of pipes 11 in sequence, and then flows out from another set of adapter interfaces 90 . The multiple pipes 11 can ensure that the adapter interfaces 90 are all located on the cover plate 9 on one side.

[0055] In the second embodiment, a set of adapter interfaces 90 are provided on the cover plates 9 at both ends of the heating plate 1 . The number of pipes 11 in the heating plate 1 is odd and two adjacent sets of pipes 11 are connected end to end.

[0056] The high-temperature steam enters from the adapter interface 90 on one set of cover plates 9 , flows through the multiple sets of pipes 11 in sequence, and then flows out from the adapter interface 90 on another set of cover plates 9 .

[0057] In the third embodiment, a set of adapters are provided on the cover plates 9 at both ends of the heating plate 1 , at least two sets of pipes 11 are provided in the heating plate 1 , and all the pipes 11 are interconnected.

[0058] The high-temperature steam enters from the adapter interface 90 of one set of cover plates 9 , flows through all the pipes 11 at the same time, and then converges and flows out from the adapter interface 90 on another set of cover plates 9 .

[0059] In this embodiment, a copper tube 13 is provided in the pipeline 11 . The copper tube 13 can improve the heat transfer efficiency and protect the pipeline 11 from being damaged by steam.

[0060] The utility model provides a corrugated paper base paper heating device. Compared with the prior art, the adapter interface 90 is connected to the steam pipe 11. The high-temperature steam enters the pipe 11 through the adapter interface 90 to heat the heating plate 1. The heat insulation plate 12 in the heating plate 1 can control the heat to converge on one side of the arc surface 10. Before processing, the base paper needs to pass around the front roller 3 and then be close to the arc surface 10, and then pass around the rear roller 4 for output. The base paper will be heated when it is close to the arc surface 10. The heat insulation plate 12 can effectively guide the direction of heat transfer and reduce heat waste.

[0061] In the absence of conflict, the above embodiments and features therein may be combined with each other.

[0062] 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.
