AI Technical Summary
In the existing lunch box raw material drying device, the air volume received by the pulp board raw material and the conveyor belt is small, resulting in low drying efficiency and reduced efficiency when piles of raw materials accumulate.
A tape conveyor is equipped with a feeding mechanism, which disperses the raw materials of the pulp board through the rotating feeding plate and guides the air flow blown out by the blowing head. The raw materials are dried in combination with hot air components to ensure uniform heating.
The drying efficiency of pulp board raw materials is improved, and the drying uneven problem caused by local overheating or accumulation is avoided, thereby achieving faster drying effect.

Description
Technical Field
[0001] The utility model relates to the technical field of lunch box raw material processing, in particular to a lunch box raw material drying device. Background Art
[0002] Pulp lunch boxes are widely used in the fast food and fast food industries due to their biodegradability, low pollution, and low price. During the production of pulp lunch boxes, the partially dried pulp board raw materials need to be pressed and formed, and then dried, sterilized, and shaped before they can be packaged, transported, and used. To improve drying efficiency, current lunch box raw material drying equipment uses a conveyor belt and a hot air blower to dry the pulp raw materials while conveying them. However, the part of the pulp board raw material that is in direct contact with the conveyor belt is exposed to less air, so it takes longer to ensure that all the pulp board raw materials are fully dried. When the pulp board raw materials accumulate on the conveyor belt, the drying efficiency of the pulp board raw materials will also decrease. Utility Model Content

The multiple material-diverting plates 607 are provided to increase the material-diverting rate.
[0027] The hot air component 5 includes a fan 501, a heater 505, and a screen plate 504. The screen plate 504 is fixedly mounted on the inner wall of the drying box 1. The upper surface of the screen plate 504 is flush with the bottom inner wall of the discharge port 3. The output end of the fan 501 is connected to a diverter pipe 502 through a pipeline. The diverter pipe 502 is located in the drying box 1. The right side of the diverter pipe 502 is connected to a ventilation pipe 503.

[0031] Working principle: When in use, turn on the three belt conveyors 4, turn on the fan 501 and the heater 505, and the belt conveyor 4 transports the raw materials. The fan 501 generates airflow, which is diverted by the diverter pipe 502 and enters the ventilation pipe 503, and then enters the drying box 1 from the exhaust hole on the ventilation pipe 503. The heater 505 heats the heating wire 506, and the heated heating wire 506 heats the airflow passing through it, thereby generating hot air. The hot air flows from bottom to top and dries the raw materials on the belt conveyor 4. At the same time, the motor 602 is turned on to drive the rotating shaft 605 to rotate, and the rotating disk 606 rotates the belt conveyor 4. The movable material stripping plate 607 rotates, and the rotating material stripping plate 607 lifts the pulp board raw materials on the belt conveyor 4 to prevent the pulp board raw materials from being in contact with the belt conveyor 4 at one part, which leads to the problem that this part cannot be dried in time. It can also disperse the piles of pulp board raw materials, and the air flow in the ventilation pipe 503 enters the diversion bin 10 from the connecting pipe 9, and then enters the blowing head 604 from the air inlet pipe 11, and blows from the blowing head 604 to the lifted raw materials, so that the lifted raw materials move along the conveying direction of the belt conveyor 4, so that the raw materials can fall onto the belt conveyor 4 and continue to be conveyed by the belt conveyor 4.
[0032] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
