Description

Technical Field

[0001] The invention relates to a drying device, in particular to a paper drying device. Background Art

[0002] When people use ink, gouache, watercolor or acrylic and other materials to create color works, they need to wait a certain amount of time for the work to dry after the creation is completed. However, when the time for waiting for the work to dry is limited, such as art students taking art exams, due to limited conditions, they cannot complete the drying of the work within the specified time or use ordinary hair dryers to dry the paper of the work. Subsequent uncontrollable conditions may damage the work that is not completely dried, which will affect the final score of the work to a certain extent, especially when drying with non-professional tools such as ordinary hair dryers. Due to uneven drying and excessively high temperature, the work material may crack, color distort, uneven paper stretching, etc. At present, there is no special paper drying device for art exams in the market application, and the strategy of using natural drying of works generally does not have enough time. Art students generally use ordinary hair dryers, small fans and other non-professional tools to dry or blow dry the paper of their works. Summary of the invention

[0019] Reference Figure 1, a paper drying device comprises: a drying shell 100, wherein an upper baffle 110 and a lower baffle 120 are sequentially arranged in the drying shell 100 from top to bottom, wherein the upper baffle 110 and the lower baffle 120 sequentially divide the interior of the drying shell 100 from top to bottom into an upper ventilation cavity, a drying cavity, and a lower ventilation cavity, wherein the upper baffle 110 is provided with a plurality of upper ventilation holes 111, and the lower baffle 120 is provided with a plurality of lower ventilation holes 121, and a first ventilation port 130 and a second ventilation port 140 are opened on one side wall of the drying shell 100, and with the first ventilation port 130 and the second ventilation port 140 facing the left relative direction, a third ventilation port 150 and a fourth ventilation port 160 are arranged on the right side wall of the drying shell 100, wherein the first ventilation port 130 and the third ventilation port 150 are respectively communicated with the upper ventilation cavity, and the second ventilation port 140 and the fourth ventilation port 160 are respectively communicated with the lower ventilation cavity, and the drying A side wall of the shell 100 is provided with a feed port interconnected with the drying cavity, and a sealing plate is detachably connected to the drying shell 100, and the sealing plate is used to seal the feed port; a left air-guiding shell 200, a right side wall of the left air-guiding shell 200 is provided with a first air inlet 210 and a first air outlet 220, the first air inlet 210 is interconnected with the first vent 130, and the first air outlet 220 is interconnected with the second vent 140; a right air-guiding shell 300, a left side wall of the right air-guiding shell 300 is provided with a second air inlet 310 and a second air outlet 320, the second air inlet 310 is interconnected with the fourth vent 160, and the second air outlet 320 is interconnected with the third vent 150; a fan 400, so that a circulating airflow is formed in the left air-guiding shell 200, in the upper ventilation cavity, in the right air-guiding shell 300 and between the lower ventilation cavity; a heating element 500 is located in the circulating airflow.

[0020] As can be seen from the above, the paper to be dried is placed into the drying chamber from the feed port, and the fan 400 forms a circulating airflow in the left air guide housing 200, the upper ventilation cavity, the right air guide housing 300 and the lower ventilation cavity, and uses the heating element 500 to heat the circulating airflow. When the circulating airflow passes through the upper ventilation cavity and the lower ventilation cavity, the circulating airflow will separate part of the hot airflow into the drying cavity to dry the paper in the drying cavity. When the airflow enters the drying cavity from the upper air guide cavity through the upper ventilation hole 111 of the upper baffle 110, the upper ventilation hole 111 will weaken the wind force and output a breeze to avoid strong wind blowing directly on the paper and affecting the finished work. Similarly, when the airflow enters the drying chamber from the lower air guide cavity through the lower ventilation holes 121 of the lower baffle 120, the lower ventilation holes 121 will weaken the wind force and output a breeze. In addition, after the airflow entering the drying chamber from the upper ventilation holes 111 collides with the lower ventilation holes 121, it will affect turbulence in the drying chamber, making the temperature in the drying chamber more uniform, which can fully dry the paper and improve the drying efficiency of the paper. Therefore, the present invention can not only efficiently dry the paper, but also reduce the impact of the finished work on the paper, so that the work can be kept as authentic as possible, with a high overall safety factor and high reliability. After drying, the paper can be taken out from the feed port.

[0021] One or more fans 400 can be selected, and they can mainly make the air flow.

[0024] In order to improve the convenience of loading the paper into the drying space, the lower baffle 120 is slidably connected to the inner wall of the drying shell 100, and the lower baffle 120 can slide in and out of the feed port, such as a guide rail is provided on the lower baffle 120, and a guide groove connected to the guide rail is provided on the inner wall of the drying shell 100, and the sliding is achieved by the mutual connection of the two. When the paper to be dried is placed in the drying cavity, the lower baffle 120 can be pulled out of the drying shell 100, and then the paper is placed on it, and then the lower baffle 120 is pushed back into the drying cavity, which is more convenient to use.

[0025] A support plate is provided in the drying chamber, and a plurality of support plates are connected between the support plate and the lower baffle 120, and air holes are provided on the surface of the support plate. The airflow entering the drying chamber from the lower air holes can better dry the paper on the support plate, and the air holes can provide a channel for the airflow to flow, and the airflow blows to the support plate and then diffuses to the surroundings from the air holes, so as to avoid the problem of blowing through the paper when the wind blows the paper from below because there is not enough space at the bottom of the paper for the airflow to pass through.

[0026] In order to facilitate the fixing of the paper, in this embodiment, a plurality of spring clips are arranged on the top surface of the support plate. The spring clips on the support plate can be used to fix the paper again to prevent the paper from being blown over and folded by the circulating airflow during the drying process.
