The heating element uses a gas heater device, and different heating modes are selected according to process requirements. The heated air is quickly distributed in the whole drying area through the fan 2, the heat efficiency is improved, the top of the air heating mechanism 3 is provided with a ventilation opening, the top of the air heating mechanism 3 is provided with a ventilation opening, which ensures that the heated hot air can flow uniformly and be discharged smoothly, prevents local temperature from being too high and causes equipment damage, and the inside of the placing plate 4 is provided with a plurality of through holes, the inside bottom of the shell 1 is provided with a circulating air inlet 5, the inside of the shell 1 is provided with a gas conveying groove 6, and the bottom of the gas conveying groove 6 is fixedly connected with a circulating air outlet 7, the circulating air inlet 5 is used to introduce hot air into the drying area, and the gas conveying groove 6 guides the hot air to the circulating air outlet 7, and finally the air is sent back to the air heating mechanism 3 by the circulating air outlet 7, so that the air can be uniformly distributed to the whole drying area, thereby realizing more efficient hot air circulation, the top of the circulating air outlet 7 is fixedly connected outside the air heating mechanism 3, four rotating shafts I 8 are rotatably connected in the inside of the shell 1, as a fixing frame, the feeding door 9 is fixed in the feeding port of the shell 1, the feeding door 9 is rotatably connected outside the rotating shaft I 8, the connection between the feeding door 9 and the rotating shaft I 8 is rounded, two insulating plates are fixedly connected on one side close to the two air heating mechanisms 3, and a full empty space is formed between the two insulating plates.

[0029] Working principle: first, the pulp layer paper enters the shell 1 through the feeding door 9, the feeding door 9 is connected with the feeding port of the shell 1, and is rotated through the rotating shaft I 8. When the pulp layer paper enters the equipment, it will be placed on the placing plate 4 in the inside of the shell 1, and the placing plate 4 has a plurality of through holes to ensure that the hot air can pass through the paper uniformly. The function of the placing plate 4 is to support the pulp layer paper, so that it can maintain a stable position during the drying process, and avoid affecting the drying effect due to movement;

[0030] At the same time, the hot air heating mechanism installed in the shell 1 starts to work. Two fans 2 provide air flow through air supply, and the air is heated to the required temperature through the air heating mechanism 3. The fan 2 distributes the hot air to the drying area to ensure that the air flows uniformly and effectively heats the pulp layer paper. The flow of the heated air is smooth, is transmitted to the circulating air outlet 7 through the gas conveying groove 6 of the shell 1, and is returned to the air heating mechanism 3, thereby forming a hot air circulation system, improving the drying efficiency;

[0031] In the drying process of the pulp layer paper, the turnover mechanism plays a key role.

The clamping assembly is composed of a rotary motor 21, a lead screw 20, a clamping plate 18 and a copying plate 17. The oblique angle design of the copying plate 17 can effectively clamp the pulp layer paper. The clamping plate 18 drives the lead screw 20 to rotate through the rotary motor 21, and then the clamping plate 18 slides through the external screw of the lead screw 20, so as to turn over the pulp layer paper and realize the simultaneous heating of both sides. The rotation of the clamping assembly is driven by the rotating gear 14 and the tooth wall 13. The rotating force is transmitted to the clamping plate 18 through the rotating shaft 15, and the pulp layer paper is turned over to realize the simultaneous heating of both sides.

[0032] After the turnover process, the hot air continues to heat the two sides of the pulp layer paper through the through hole of the placing plate 4, so as to avoid the warping or incomplete drying caused by uneven heating. In addition, the circulating air inlet 5 and the circulating air outlet 7 in the equipment form an effective air reflux system. The circulating air inlet 5 introduces hot air into the drying area, and the circulating air outlet 7 discharges the used hot air. Finally, the air heating mechanism 3 reheats and recycles the used hot air. This circulation system reduces energy waste and improves the thermal efficiency of the equipment.
