Technical Field

[0001] The utility model relates to the technical field of papermaking ovens, and particularly relates to a self-cleaning papermaking oven net. Background Art

[0002] With the progress of technology, in some paper mills, a circulating hot air oven is used to dry some paper molds and paperboards in the papermaking industry, greatly improving the production efficiency.

[0003] After most existing circulating hot air ovens are used for a period of time, a large amount of impurities will accumulate on the oven net due to long-term use, which is extremely easy to block the oven net, thus seriously affecting the air volume and drying effect, resulting in too long drying time, increased production cost and decreased production efficiency. Therefore, workers need to regularly disassemble and clean the oven net to keep the oven net unblocked and ensure the stability of the ventilation volume and drying efficiency. However, the manual cleaning process is relatively complex, time-consuming and laborious, seriously affecting the production efficiency. Therefore, a self-cleaning papermaking oven net is proposed to solve the above problems. Summary of the Utility Model

Detailed implementation manners

[0022] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a self-cleaning paper-making oven mesh, including an oven housing 1, a second motor 15 is fixedly connected to one side of the oven housing 1, a fixed block 18 is fixedly connected to the inside of the oven housing 1, a bidirectional lead screw 16 is rotatably connected to one side of the fixed block 18, the bidirectional lead screw 16 is fixedly connected to the output end of the second motor 15, a hot air blower 9 is fixedly connected to the top of the oven housing 1, an exhaust pipe 13 located inside the oven housing 1 is fixedly connected to the air outlet of the hot air blower 9, the exhaust pipe 13 is telescopic, an air outlet hood 14 is fixedly connected to one end of the exhaust pipe 13, a threaded block 17 is fixedly connected to one side of the air outlet hood 14, and the threaded block 17 is threadedly connected to the bidirectional lead screw 16;

[0024] Among them, the threaded block 17 abuts against the inner wall of the oven housing 1 to prevent the threaded block 17 from rotating when the bidirectional lead screw 16 rotates;

[0025] Start the hot air blower 9 and the second motor 15. The output end of the second motor 15 drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 drives the threaded block 17 to move reciprocally. The threaded block 17 drives the air outlet hood 14 to move reciprocally;

[0026] This setting can make the air outlet hood 14 swing reciprocally during the operation of the oven, so that the air outlet hood 14 can blow air into the device internally in multiple directions reciprocally, achieving the purpose of uniform heating, improving the drying speed, and accelerating the production efficiency.

[0027] On one side of the oven shell 1, a first motor 2 is fixedly installed. Inside the oven shell 1, two first rotating shafts 3 are rotatably connected. An oven mesh 4 is rotatably connected to the two first rotating shafts 3. The oven mesh 4 is made of Teflon material. One of the first rotating shafts 3 is fixedly connected to the output end of the first motor 2. One end of the first rotating shaft 3 fixedly connected to the output end of the first motor 2 is fixedly sleeved with a first gear 5. Inside the oven shell 1, a second rotating shaft 7 is rotatably connected. One end of the second rotating shaft 7 is fixedly connected to a second gear 6. The second gear 6 and the first gear 5 are meshed. A cleaning brush 8 is fixedly connected to the second rotating shaft 7;

[0028] The oven mesh 4 is made of Teflon material, which has good air permeability, high temperature resistance, anti-bending fatigue, saves heat source consumption, improves drying efficiency, has a long service life, and reduces production costs.

[0029] After drying is completed, take out the finished product on the surface of the oven mesh 4, and then start the first motor 2. The output end of the first motor 2 drives the first rotating shaft 3 to rotate. The first rotating shaft 3 drives the oven mesh 4 to rotate. While the first rotating shaft 3 rotates, it drives the first gear 5 to rotate. The first gear 5 drives the second gear 6 to rotate. The second gear 6 drives the second rotating shaft 7 to rotate. The rotation of the second rotating shaft 7 drives the cleaning brush 8 to rotate. At this time, the cleaning brush 8 can clean the dust and impurities on the surface of the oven mesh 4, avoiding blockage caused by excessive dust and impurities on the surface of the oven mesh 4, thus ensuring the ventilation effect of the oven mesh 4, making its drying efficiency stable, eliminating the need for manual disassembly and cleaning of the oven mesh 4, saving manpower, and improving production efficiency.

[0030] One side of the hot air blower 9 is threadedly connected with a dust collection box 10. One side of the hot air blower 9 is fixedly connected with a second air inlet pipe 19. The second air inlet pipe 19 is slidably connected inside the dust collection box 10. One side of the second air inlet pipe 19 is fixedly connected with a filter element 20. The filter element 20 is slidably connected inside the dust collection box 10. One side of the dust collection box 10 is fixedly connected with a first air inlet pipe 11. One end of the first air inlet pipe 11 that does not contact the dust collection box 10 is fixedly connected with a dust suction port 12;

[0031] During the cleaning process of the cleaning brush 8, the hot air blower 9 is started to suck the dust and impurities cleaned by the cleaning brush 8 from the first air inlet pipe 11 into the dust collection box 10 through the dust suction port 12. The setting of the dust collection box 10 can collect the dust and impurities cleaned by the cleaning brush 8 together. The setting of the filter element 20 prevents the second air inlet pipe 19 from sucking the dust inside the dust collection box 10 back into the oven interior, causing secondary pollution. Moreover, the dust collection box 10 is detachable, facilitating its cleaning, eliminating the need for manual cleaning of impurities every time the cleaning brush 8 finishes cleaning the oven mesh 4, avoiding secondary pollution to the oven interior caused by secondary dust cleaning, improving the cleaning efficiency, and improving production efficiency.

[0032] The hot air blower 9 sucks the hot air in the drying oven through the first intake pipe 11 and the second intake pipe 19, and then discharges the hot air into the drying oven through the outlet pipe 13, which not only maintains the air circulation in the drying oven, but also improves the drying efficiency. There is no need to reheat the outside air, saving the power consumption of the hot air blower 9 and reducing the production cost.

[0033] Working principle: Start the first motor 2. The output end of the first motor 2 drives the first rotating shaft 3 to rotate. The first rotating shaft 3 drives the drying oven mesh 4 to rotate. While the first rotating shaft 3 rotates, it drives the first gear 5 to rotate. The first gear 5 drives the second gear 6 to rotate. The second gear 6 drives the second rotating shaft 7 to rotate. The rotation of the second rotating shaft 7 drives the cleaning brush 8 to rotate. At this time, the cleaning brush 8 can clean the dust and impurities on the surface of the drying oven mesh 4.

[0034] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
