[0002] Gypsum board is one of the materials widely used in modern construction. During the production process, the wet gypsum board needs to be dried by drying equipment. In the existing gypsum board drying equipment, the gypsum board is generally dried by a wind box (bellows). Specifically, a wind box is set at the upper part and the lower part of the gypsum board conveying path, and a plurality of air outlets are opened on the surface of the wind box. The external air source is connected to the wind box to supply air. The air is blown from the air outlet of the wind box to the surface of the gypsum board to dry the gypsum board. For example, the application number is 201410142297.5, the application date is April 10, 2014, and the patent name is "Gypsum Board Drying Equipment".

[0003] However, the air box structure for drying gypsum boards, including the above-mentioned technical solutions, generally has the following defects: the existing air boxes are all integral, and the external air source is directly connected to the air box as a whole to supply air. Although the integral air box has the advantages of low processing cost and easy installation, it is difficult to disassemble and maintain it. Once the air outlet of the air box is blocked or the air box itself is damaged, the air box needs to be disassembled as a whole, and when the width of the gypsum board changes, it is difficult to adjust the air box in time to meet the drying requirements. Therefore, designing an air box structure that is easy to disassemble and maintain and repair has become an urgent problem to be solved in this field. Utility Model Content

[0023] Figures 1 to 5 This is the best embodiment of the present invention, Figures 1 to 5 The utility model is further described.

[0024] like Figure 1 As shown, a wind box mechanism of a gypsum board drying device (hereinafter referred to as the wind box mechanism) includes a mounting plate 1 and a fixing frame 4 arranged at intervals. In the gypsum board drying device, the mounting plate 1 and the fixing frame 4 are fixed at intervals in the gypsum board drying device along the transportation direction of the gypsum board.

[0025] Several air boxes 3 are installed between the mounting plate 1 and the fixing frame 4. Multiple air boxes 3 are spaced apart between the mounting plate 1 and the fixing frame 4. Each air box 3 passes through the surface of the mounting plate 1 and extends to the fixing frame 4. Locking mechanisms 2 corresponding to the number of air boxes 3 are arranged on the surface of the mounting plate 1. After the air boxes 3 are installed in place, they are locked by the locking mechanisms 2.

[0026] Combine Figures 2 and 3 The locking mechanism 2 includes a locking plate 5 fixed to the upper part of the mounting plate 1 by a locking bolt 6. The locking plate 5 is rotatably connected to the mounting plate 1 and is vertically turned outward at the air inlet of the air box 3 to form a card plate 7. After the air box 3 is installed in the mounting plate 1, the card plate 7 is clamped on the surface of the mounting plate 1, and the locking plate 5 is rotated to clamp the card plate 7 on the surface of the mounting plate 1 to achieve the fixation of the air box 3.

[0027] Combine Figure 5The mounting plate 1 is a rectangular plate-like structure with a plurality of mounting holes 11 formed on its surface. A locking hole 12 is provided above each mounting hole 11. The locking hole 12 is a threaded hole that is threadedly connected to the locking bolt 6. The locking bolt 6 passes through the locking plate 5 and is screwed into the locking hole 12, completing the installation of the locking plate 5.

[0028] The mounting plate 1 is the air inlet end of the air box mechanism. The size of the mounting plate 1 is connected to the air supply port in the gypsum board drying equipment. After the mounting plate 1 is connected to the air supply port, the air supply to the air box 3 is realized. Figure 4 As shown, the wind box 3 is a rectangular tubular structure with one end open. The above-mentioned clamping plate 7 is arranged at the open end of the wind box 3. The closed end of the wind box 3 is closed by a fixing plate 8. A plurality of air jet holes 10 are opened on the end surface of the wind box 3 body facing the gypsum board. The dry gas entering from the open end of the wind box 3 is ejected from the air jet holes 10 after entering the wind box 3 to dry the gypsum board.

[0029] The diameter of the air box 3 gradually decreases from the open end (mounting plate 7) to the closed end (fixing plate 8). Specifically, the height of the air box 3 gradually decreases from the open end (mounting plate 7) to the closed end (fixing plate 8). The opening area of the mounting hole 11 on the surface of the mounting plate 1 is larger than the area of the fixing plate 8 and smaller than the area of the mounting plate 7, allowing the closed end of the air box 3 to pass through the mounting hole 11 and extend to the fixing frame 4.

[0030] The fixing plate 8 also serves to fix the air box 3. After extending to the fixing frame 4, the fixing plate 8 is fixed by a plurality of fixing bolts 9, thereby achieving the effect of tightening the air box 3 and fixing the closed end of the air box 3 at the same time, playing a double insurance role and facilitating adjustment and repair.

[0031] The specific working process and working principle are as follows:

[0032] Arrange the corresponding number of air boxes 3 according to the number of mounting holes 11 on the surface of the mounting plate 1, rotate the locking plate 5 to clear the mounting holes 11, and then pass the air boxes 3 through the mounting holes 11. At this time, the fixing plate 8 passes through the mounting holes 11 along with the box body of the air box 3 and extends to the fixing frame 4. At the same time, the fixing bolts 9 are used to fix the fixing plate 8 to the fixing frame 4. At this time, the clamping plate 7 is clamped at the opening of the mounting hole 11 and fits against the surface of the mounting plate 1. Rotate the locking plate 5 to clamp the clamping plate 7 to the surface of the mounting plate 1, and the air boxes 3 are fixed.

[0033] The mounting plate 1 is connected to the air supply port of the drying equipment to realize air supply to the air box 3. The dry gas entering from the open end of the air box 3 is ejected from the air jet hole 10 after entering the air box 3 to dry the gypsum board.

[0034] As can be seen from the above, in this wind box mechanism, the wind boxes 3 are designed as multiple independent detachable structures, which facilitates the disassembly and assembly of the wind boxes 3 and realizes rapid maintenance of the wind boxes 3. Different numbers of wind boxes 3 can be set according to the width of the gypsum board, which has higher applicability.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
