Description

Technical Field

[0001] The invention relates to a three-dimensional drying room without a circulation bracket. Background Art

[0002] After the batch processing of the integrated panels is completed, the outer surface of the integrated panels needs to be painted to improve the aesthetics and surface quality of the integrated panels. The integrated panels need to be left for a period of time after painting, and the subsequent processing steps can only be carried out on the integrated panels after the paint is completely dry. However, most of the existing integrated panels are dried naturally or by a drying device. The disadvantages of using the naturally dried integrated panels are: 1. The drying time is long, which makes the production and processing efficiency of the integrated panels low; 2. The painted integrated panels dried under natural conditions will be adhered to the integrated panels after painting due to the influence of the working environment, which is not conducive to the aesthetics of the integrated panels; the disadvantages of using a drying device to dry the integrated panels are: 1. Heat is easily lost, and a large amount of hot air will surge out, which is easy to cause damage to external equipment and human body; 2. The structure of the existing drying device is not compact, and the drying process cannot achieve continuous cycle operation, resulting in low thermal efficiency and low drying efficiency; 3. In actual use, the existing drying device needs to dry one side of the integrated panel first, and then turn the integrated panel over to dry the other side after the drying is completed. This method is relatively complicated to operate and has a large workload.

[0003] Chinese patent document number CN211989371U disclosed in 2020 a mechanical paint spraying device with fast drying. The specific disclosed type includes a bottom plate, a box body is fixed on the top of the bottom plate by supporting legs, and the interior of the box body is divided into a spraying chamber, a first drying chamber, and a second drying chamber from right to left by partitions; the top of the box body is penetrated by an injection pipe extending into the interior of the spraying chamber, and the injection pipe is located inside the spraying chamber. One end of the injection pipe is connected to the spraying structure. Through the combined use of the spraying chamber, the first drying chamber, the second drying chamber, the injection pipe, and the spraying structure, it is possible to dry the paint in time after spraying. However, this structure still has the problem of easy heat loss and the inability to dry the other side of the wooden board at the same time.

[0004] Therefore, further improvements are necessary. Summary of the Invention
