[0002] With the development of society and the progress of science and technology, the papermaking industry is also constantly seeking more efficient, environmentally friendly production methods. In the many links of paper production, drying and setting is one of the important steps to ensure product quality. Traditional paper drying and setting methods mostly use hot air drying or steam heating and other ways. Although these traditional methods can meet the basic drying requirements of paper, they have certain limitations in energy consumption, efficiency and the impact on paper quality.

[0003] First, in terms of energy consumption, traditional drying methods usually consume a large amount of heat energy to evaporate the moisture in the paper, which not only leads to waste of energy, but also increases production costs. Secondly, in terms of drying efficiency, due to the limited heat transfer efficiency of hot air or steam, the drying speed is slow, affecting the overall efficiency of the production line.

[0004] Therefore, the present application proposes a paper drying and setting device to solve the above technical problems. SUMMARY

[0005] The main purpose of the utility model is to solve the above-mentioned shortcomings, provide a paper drying and setting device, which uses microwave heating supplemented by heating roller pressing to dry and set the paper, reducing energy consumption while improving overall drying efficiency.

DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] As shown in Figures 1-6 The utility model provides a kind of paper drying setting device, comprising:

[0026] Two groups of hot press roller assemblies 1, symmetrically set at the both ends of base 2, for paper heat pressing drying;

[0027] Protective cover 3 is fixedly arranged at the top of base 2;

[0028] Multiple microwave generators 4 are evenly arranged and fixedly arranged at the top of protective cover 3, for outputting microwave to the cavity formed between base 2 and protective cover 3;

[0029] Isolation cover 5 is fixedly arranged at the top of protective cover 3 and completely covers multiple microwave generators 4;

[0030] A moisture absorption and exhaust assembly 6 is arranged on the isolation cover 5 and is used to exhaust the moisture generated during the drying of the paper.

[0031] In use, the paper is input from the heat press roller assembly 1 at one end of the base 2 and is output from the heat press roller assembly 1 at the other end. The heat press roller assembly 1 functions to dry and shape the paper and also functions to convey the paper. Since the heat press roller assembly 1 directly contacts the paper, the heat transfer efficiency is high. The paper between the two heat press roller assemblies 1 is subjected to the microwave emitted by the microwave generator 4, and the internal moisture is evaporated. Unlike the traditional conduction or convection heating method, the microwave can penetrate the paper to the inside, so that the paper is heated inside and outside at the same time, the drying speed is accelerated, the uniformity of drying is ensured, the shape and structure of the material are better maintained, and the heat loss is reduced.

[0032] The microwave generator 4 and the heat press roller assembly 1 jointly heat the paper, which improves the drying efficiency and reduces the energy consumption due to the high thermal efficiency of the two heating methods. The protective cover 3 and the isolation cover 5 prevent the microwave from overflowing, the moisture generated during the drying of the paper passes through the protective cover 3 and the isolation cover 5, is absorbed by the moisture absorption and exhaust assembly 6, and is exhausted.

[0033] In an embodiment, the heat press roller assembly 1 includes an upper heat press roller 101 and a lower heat press roller 102 rotatably arranged at one end of the base 2, a set of synchronous gears 103 fixedly arranged at the end portions of the upper heat press roller 101 and the lower heat press roller 102 and meshing with each other, and a sprocket 104 fixedly arranged at the other end of the lower heat press roller 102. The sprockets 104 between the two heat press roller assemblies 1 are drivingly connected through a chain 7, and one of the heat press roller assemblies 1 is drivingly connected with a driving assembly 8. The driving assembly 8 includes a speed reduction motor 81 fixedly arranged on the base 2 and a driving gear 82 fixedly arranged at the output end of the speed reduction motor 81 and meshing with the synchronous gear 103 on the lower heat press roller 102.

[0034] In this way, the speed reduction motor 81 drives the driving gear 82 to rotate, the driving gear 82 drives the synchronous gear 103 meshing therewith to rotate, the synchronous gear 103 drives the other synchronous gear 103 meshing therewith to rotate, so that the upper heat press roller 101 and the lower heat press roller 102 in the same heat press roller assembly 1 rotate in opposite directions. The lower heat press roller 102 in the heat press roller assembly 1 rotates while driving the lower heat press roller 102 in the other heat press roller assembly 1 to rotate in the same direction through the sprocket 104 and the chain 7. The lower heat press roller 102 drives the upper heat press roller 101 meshing therewith to rotate in the opposite direction, so that the two heat press roller assemblies 1 rotate synchronously, the paper is subjected to heat press drying and conveying.

[0035] In an embodiment, a plurality of supporting rollers 9 are rotatably arranged on the base 2 and are uniformly arranged between the two heat press roller assemblies 1 to support the paper.

[0036] In this way, the part of the paper between the two groups of hot pressing roller assemblies 1 is supported by the supporting roller 9, so as to avoid the paper from falling due to its own weight, which adversely affects the conveying and hot pressing.

[0037] In an embodiment, the base 2 is provided with a height-adjustable straightening assembly 10, which comprises a long strip-shaped limiting hole 1001 symmetrically formed on both sides of the base 2, a rotating support 1002 with both ends slidingly inserted into the limiting hole 1001, a pressing roller 1003 rotatably arranged on the rotating support 1002, a stud 1004 fixedly arranged at one end of the rotating support 1002 penetrating through the limiting hole 1001, and a positioning block 1005 fixedly arranged on the base 2 for penetrating the stud 1004.

[0038] In this way, by arranging the straightening assembly 10, the part of the paper between the two groups of hot pressing roller assemblies 1 is in a straightened state, which avoids the paper from being folded during the conveying and drying process, thereby affecting the product quality. The positioning of the straightening assembly 10 can be completed by fixing the stud 1004 on the positioning block 1005 using a bolt, which ensures that the pressing roller 1003 abuts and presses the paper, so that the paper is in a straightened state. The height of the pressing roller 1003 is adjusted by adjusting the length of the stud 1004 inserted into the positioning block 1005, so as to adjust the pressing degree of the pressing roller 1003 on the paper, thereby ensuring that the paper is straightened without being broken.

[0039] In an embodiment, the top of the protective cover 3 is provided with a through hole 11, and the moisture absorption and air exhaust assembly 6 comprises a multi-channel air suction pipe 61 communicated with the top of the isolation cover 5, a flow collection pipe 62 communicated with the multi-channel air suction pipe 61, and an air exhaust fan 63 arranged on the flow collection pipe 62.

[0040] In this way, after the air exhaust fan 63 is turned on, the moisture generated due to the drying of the paper in the protective cover 3 is subjected to suction and passes through the through hole 11 and the isolation cover 5 into the multi-channel air suction pipe 61, and is then discharged after being collected by the flow collection pipe 62, thereby ensuring the dryness of the inside of the device.

[0041] In an embodiment, the two sides of the protective cover 3 are provided with a plurality of transparent windows 12.

[0042] In this way, the operator can observe the drying condition of the paper in the protective cover 3 in real time through the transparent windows 12.

[0043] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that the present application can be implemented in other embodiments without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the present application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

[0044] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0045] In addition, "a plurality of" means two or more. In addition, the technical solutions among various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the protection scope required by the present application.
