Problems solved by technology

Although it can improve the drying speed of gouache painting, its existing problems are: 1. Due to repeated smearing of gouache brush and ink, if it is dried and heated by a contact electric heating plate, the thicker place and the thinner place where the pen and ink are smeared, The paper will inevitably be distorted and deformed, and the whole paper will be heated unevenly due to the inconsistent thickness of the actual pen and ink. The temperature of the local area of ​​the gouache painting will be too high, which will easily damage the quality of the gouache painting and easily cause local distortion of the gouache painting.
2. The drying efficiency of the above-mentioned dryers is low. One dryer can only dry one gouache painting at a time, and the drying efficiency is low. In order to improve the drying efficiency, the number of dryers can only be increased, which leads to the fact that the dryer occupies a large area in the examination room. Large area

Embodiment 1

[0035] figure 1 It is a schematic diagram of the overall structure of the present invention, figure 2 Yes figure 1 A-A cross-sectional view, image 3 Yes figure 1 The B-B direction sectional view of the figure, combined with the accompanying drawings, it can be seen that the integrated dryer for drying gouache paintings includes an oven 1, and one side of the oven 1 is provided with an oven door 3 that can be opened and closed, and the oven door 3 A fan group 12 and an electric heat source group 11 are arranged on the opposite side of the wall, and the fan group 12 can blow the heat of the electric heat source group 11 into the oven 1, and several layers of drawing papers for fixing gouache paintings are arranged in the oven 1. Grid frame 9, described drawing paper fixing grid frame 9 can be pulled out from oven 1 and pushed in oven 1, and the air outlet side of described fan group 12 is provided with baffle plate 10, and described baffle plate 10 The wind blown out by th...

Embodiment 2

[0052] This embodiment discloses a gouache painting drying device with another structural form. The difference between it and Embodiment 1 is that, in order to obtain a uniform wind speed in Embodiment 1, baffles are used, while in this embodiment, a baffle is formed in an oven. A slow flow area, so that the air flow can enter the drying area in a laminar flow, so as to ensure that the air flow will not cause fluctuations in the vertical direction. At the same height, the flow rate of the air flow is consistent, specifically as Figure 4 As shown, including the oven, the oven is divided into four areas distributed sequentially along the airflow direction by three vertical partitions arranged vertically: the hot air area, the slow air area, the drying area, and the return air area, and the return air area passes through The dehumidification module communicates with the air inlet of the hot air area; wherein: a fan is arranged at the air inlet of the hot air area, and an electric...

Abstract

The invention discloses a gouache drying method and device. According to the gouache drying device, in order to obtain even hot air, a baffle plate is arranged in a drying oven, and even an air buffer area is arranged; and meanwhile, when a gouache is dried, a spoiler is arranged to enable airflow to be capable of evenly and transversely flowing along the gouache. Thus, the gouache drying method and device can effectively solve the problem of image distortion caused by uneven partial heating of the gouache.

Description

technical field [0001] The invention belongs to the technical field of product drying, in particular to a drying method and device for gouache painting. Background technique [0002] In view of the current situation of the art college entrance examination and high school entrance examination every year, each examination room usually prepares 4-5 hair dryers in order to speed up the drying of the drawing paper when conducting the gouache painting examination. However, the hair dryers are low in efficiency and loud in noise, which affects other people. Normal drawing and answering questions. And if the wind power of the hair dryer is too large and uneven during the drying process, it will affect the effect of the gouache painting. At the same time, if the wind power of the hair dryer is too small, the drying time will be longer. There is also the Chinese patent CN203864319U "a kind of contact type gouache drying machine for art examination", which includes a base and a cover....
