Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, in particular to a drying machine for paper production. Background Art

[0002] Paper is the most commonly used item in our daily life. Whether reading, reading newspapers, writing or painting, we have to touch paper. Paper is also indispensable in industrial, agricultural and national defense production. Paper is a sheet-like fiber product used for writing, printing, painting or packaging. It is generally made of a water suspension of plant fibers that has been pulped, interlaced on a net, initially dehydrated, compressed and dried. It can be seen that the drying process required in the papermaking process is indispensable, and it is mostly completed by a papermaking dryer.

[0003] The common way of using a commonly used paper dryer is to install the dryer on both sides of a conveyor belt so that the conveyor belt passes through the inside of the dryer, and the dryer can dry the paper placed on the conveyor belt. However, when a commonly used dryer is in use, the high-temperature gas used for drying inside the dryer is unevenly distributed, causing the temperature at different positions inside the dryer to vary. This will result in the inability to dry the paper evenly during use, affecting the drying effect of the paper. Utility Model Content

The output shaft of the second motor 19 passes through the interior of the protective groove 9 and is connected to one end of the installation shaft 14 close to the inner wall of the protective groove 9 through a coupling. Fixing holes 15 are opened at the bottom of both ends of the chassis 3. The fixing holes 15 are located below the protective groove 9. The protective groove 9 can provide better protection for the fan blades 12 when in use.

[0024] As a technical optimization solution of the utility model, connecting plates 7 are installed on the opposite surfaces of the two support plates 2, grooves 6 are opened at the middle ends of the tops of the two support plates 2, and a conveyor belt 5 is installed between the two mounting plates 1. The two ends of the conveyor belt 5 are respectively located inside the two grooves 6. When in use, the staff can place paper on the conveyor belt 5 and transport the paper through the conveyor belt 5. During transportation, the first heating plate 10 located inside the chassis 3 can dry the paper.

[0025] As a technical optimization solution of the utility model, the conveyor belt 5 is located above the connecting plate 7, and a rotating shaft 16 and a connecting shaft 18 are respectively installed at the two ends of the interior of the conveyor belt 5. The two ends of the rotating shaft 16 are respectively rotatably installed on the opposite surfaces of the two mounting plates 1. The rotating shaft 16 can support one end of the conveyor belt 5 when in use.

[0026] As a technical optimization solution of the utility model, a fixing sleeve 17 is installed on the connecting shaft 18, and the outer walls of the fixing sleeve 17 and the rotating shaft 16 are both in contact with the inner wall of the conveyor belt 5. The conveyor belt 5 is located at the bottom of the chassis 3, and the tops of both ends of the conveyor belt 5 are respectively located inside the two fixing holes 15.

[0027] As a technical optimization solution of the utility model, a second heating plate 13 is installed inside the conveyor belt 5, and the top of the second heating plate 13 is abutted against the inner top of the conveyor belt 5. The two ends of the second heating plate 13 are respectively installed on the opposite surfaces of the two mounting plates 1. The second heating plate 13 can support the middle end of the conveyor belt 5 when in use to prevent the middle end of the conveyor belt 5 from deformation during use. At the same time, the bottom of the paper can also be heated and dried through the conveyor belt 5.

[0028] As a technical optimization solution of the utility model, one end of the connecting shaft 18 passes through the mounting plate 1 and is connected to the output shaft of the first motor 8 through a coupling. The first motor 8 is installed on the side of the mounting plate 1. Support rods 4 are installed at both ends of the bottom of the two support plates 2. The output shaft of the first motor 8 can drive the connecting shaft 18 and the fixed sleeve 17 to rotate.

[0029] When the utility model is in use, the staff places the paper to be dried on one end of the conveyor belt 5, and the staff starts the first motor 8. The output shaft of the first motor 8 drives the connecting shaft 18 and the fixed sleeve 17 thereon to rotate.

When the conveyor belt 5 rotates, the paper on the top thereof can be transported, so that the paper moves to the inside of the chassis 3 through the fixed holes 15 at both ends of the chassis 3.

[0030] When in use, the first heating plates 10 located at the top of the chassis 3 can heat the air inside the chassis 3. When the paper moves to the inside of the chassis 3, the high-temperature air inside the chassis 3 can heat and dry the surface of the paper. When the high-temperature air inside the chassis 3 dries the paper, the output shaft of the second motor 19 located at both ends of the chassis 3 can drive the mounting shaft 14 located inside the protective groove 9 on the inner wall of the chassis 3 to rotate. When the mounting shaft 14 rotates, it can drive the several blades 12 thereon to rotate through the mounting sleeve 11, and the several blades 12 can blow the high-temperature air inside the chassis 3, so that the high-temperature air inside the chassis 3 flows, and the temperature at different positions inside the chassis 3 is the same, so as to prevent the temperature of the position near the first heating plate 10 inside the chassis 3 from being high when in use, while the temperature at the bottom of the chassis 3 is low, resulting in poor heating and drying effect of the paper.

[0031] When in use, the second heating plate 13 located inside the conveyor belt 5 can provide good support for the middle end of the conveyor belt 5 to prevent the middle end of the conveyor belt 5 from being dented and deformed during use. At the same time, the second heating plate 13 can heat the conveyor belt 5 to prevent excessive moisture on the surface of the conveyor belt 5. At the same time, the bottom of the paper can be heated and dried through the conveyor belt 5. When in use, the first heating plate 10 and the second heating plate 13 cooperate with each other to improve the drying efficiency of the paper and make the drying of the paper more uniform.
