DETAILED DESCRIPTION

[0017] In order to enable the personnel in the technical field to better understand the present application scheme, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by the personnel in the art without making creative efforts should belong to the scope of protection of the present application.

[0018] Reference Figure 1The embodiment discloses a batch paper anti-wrinkle drying device, which avoids paper wrinkling during paper drying. The device comprises a drying chamber 1, in which the drying process of the paper 8 to be dried is completed. The drying effect of the paper 8 is greatly related to the temperature and humidity of the environment. In a suitable environment, the problems of rapid dehydration or low drying efficiency of the paper 8 can be avoided. In the embodiment, an air conditioning device 2 is arranged in the drying chamber 1 to control the temperature and humidity in the drying chamber 1. The embodiment discloses a suitable temperature and humidity range, wherein the temperature in the drying chamber 1 is 15-30 DEG C, and the humidity is 40-65%. The air conditioning device 2 comprises an air conditioner 21 to ensure that the temperature in the drying chamber 1 meets the setting. The air conditioning device 2 further comprises an exhaust fan 22 and a humidifier 23 to control the humidity in the drying chamber 1 to meet the setting.

[0019] To better place the paper 8 to be dried, a bracket assembly 3 is arranged in the drying chamber 1. In the embodiment, at least one hollow protective screen 4 for supporting the paper 8 to be dried is arranged on the bracket assembly 3. Specifically, the bracket assembly 3 comprises a stand 31 and a support frame 32. The support frame 32 is movably connected to the stand 31 through a wedge-shaped pipe 5 and can rotate relative to the stand 31, thereby facilitating the taking and placing of the paper 8. Further, a plurality of air-permeable parts are formed in the surface of the support frame 32. The hollow protective screen 4 is laid on the support frame 32 and allows gas flow through the air-permeable parts, thereby achieving the same drying efficiency on the front and back surfaces of the paper. To dry a batch of paper 8, the support frame 32 is provided in a plurality of forms. The plurality of support frames 32 are arranged in an overlapped manner at a certain distance, so as to ensure the water evaporation efficiency while drying the batch of paper 8.

[0020] Because the water content of the paper 8 to be dried and other chemical substances possibly remaining in the paper 8 before drying can cause corrosion or other reactions to the substances directly contacting the paper 8, the hollow protective screen 4 directly contacting the paper 8 needs to be made of inert materials. For example, the hollow protective screen 4 can be made of stainless steel, polyethylene, polypropylene, Teflon or a combination of the above materials to adapt to different parts of the paper 8. To improve the drying efficiency of the paper 8, a plurality of openings 6 are arranged on the hollow protective screen. In the embodiment, the area of the openings 6 of the hollow protective screen accounts for at least 80% of the total area of the hollow protective screen. The area of the air-permeable parts formed on the support frame 32 is greater than the area of the openings 6 of the hollow protective screen 4, thereby achieving the same drying speed on the front and back surfaces of the paper 8. When the paper 8 starts to dry, the water content of the paper 8 is high. To avoid the paper 8 sagging through the openings 6 due to gravity and to avoid leaving grid marks on the paper 8, the openings 6 of the hollow protective screen 4 are circular or polygonal in shape. The openings 6 can also be individually set according to different parts of the paper 8. The density of the openings 6 can also be optimized to provide sufficient support for the paper 8.

[0021] It should be noted that the evaporation rate of moisture in the paper 8 body and the paper 8 edge is different when the paper 8 is drying, and if the paper 8 is not physically treated, it will cause the paper 8 to wrinkle, so it is necessary to balance the drying speed of the paper 8 edge and the inside, and the present embodiment is provided with a water absorption plate 7 in the drying device, which is movably arranged on the hollow protective screen 4, and after the paper 8 to be dried is laid on the hollow protective screen 4, the water absorption plate 7 is pressed on the edge of the paper 8 to be dried, so as to absorb the moisture of the paper 8 edge, and balance the moisture drying speed inside the paper 8 by water absorption. In the present embodiment, the water absorption plate 7 is a wooden plate, which can also be a wooden strip, and the material can be beech, oak, sandalwood, elm, white oak, etc., or a plurality of the above materials.

[0022] In summary, by laying the paper 8 to be dried on the hollow protective screen 4, the moisture on the front and back surfaces can be evaporated synchronously, and at the same time, by pressing the water absorption plate 7 on the edge of the paper 8 to be dried, the moisture on the edge of the paper 8 can be absorbed, which can effectively avoid the deformation of the paper 8 caused by the different evaporation rates of the moisture on the edge and other parts of the paper 8.
