[0037] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] Embodiment 1

[0039] As Figure 1 、 Figure 2 shown, a gypsum board drying device, which is used in cooperation with an adsorption manipulator. When the gypsum board 40 is lifted to the top of the drying chamber 10, the adsorption manipulator penetrates through the discharge port 12 to adsorb and take out the gypsum board 40; it includes:

[0040] A drying chamber 10, the lower part of the drying chamber 10 is provided with two relatively distributed feed ports 11, the upper part of the drying chamber 10 is provided with a discharge port 12, and a plurality of groups of air ducts 13 are arranged through the drying chamber 10, and the air ducts 13 are communicated with an external hot air conveying system;

[0041] A horizontally arranged material conveying assembly 20, the material conveying assembly 20 includes at least two groups of rotatably arranged rollers one 21, and a conveyor belt 22 sleeved on the rollers one 21. The width of the conveyor belt 22 is smaller than the width of the gypsum board 40, and the conveyor belt 22 penetrates through the two feed ports 11 and the conveying direction is the same as the length direction of the gypsum board 40;

[0042] Two groups of lifting assemblies 30 longitudinally arranged inside the drying chamber 10, the two groups of lifting assemblies 30 are distributed on both sides of the width direction of the material conveying assembly 20. The lifting assembly 30 includes at least two groups of rotatably arranged rollers two 31, and a lifting belt 32 sleeved on the rollers two 31. Through holes are provided on the lifting belt 32 to ensure the circulation effect of hot air in the drying chamber 10, and a plurality of groups of support members 34 are arranged on the outer side wall of the outer ring of the lifting belt 32;

[0043] Among them, in this embodiment, the height of the drying chamber 10 and the rotation speed of the lifting belt 32 are adjusted according to the actual use situation to ensure that the drying process can be completed when the gypsum board 40 moves from bottom to top through the drying cavity. The area between the two groups of lifting assemblies 30 and the conveyor belt 22 is the drying cavity. The conveyor belt 22 conveys the gypsum board 40 to the bottom of the drying cavity, and the lifting belt 32 drives the support member 34 to move to the bottom of the drying cavity to contact the lower end surface of the gypsum board 40. The support member 34 continues to move to drive the gypsum board 40 to move synchronously through the drying cavity to complete the drying work.

[0044] A drying method for the gypsum board drying device, including the following steps:

[0045] S1. Feeding: Place the gypsum board 40 on the conveyor belt 22 outside the drying chamber 10, and the conveyor belt 22 conveys the gypsum board 40 to the bottom of the drying chamber; the traveling direction of the conveyor belt 22 is as shown by the arrow in Figure 1 ;

[0046] wherein, the length direction of the gypsum board 40 is consistent with the conveying direction of the conveyor belt 22, and both ends of the gypsum board 40 are located outside the conveyor belt 22;

[0047] S2. Lifting and drying: The lifting belt 32 rotates to drive the support member 34 to move to contact the lower end surface of the gypsum board 40 at the bottom of the drying chamber, and the support member 34 continues to move to drive the gypsum board 40 to move synchronously through the drying chamber to complete the drying work; the traveling direction of the lifting belt 32 is as shown by the arrow in Figure 2 ;

[0048] S3. Taking the material: The lifting belt 32 drives the gypsum board 40 to move to the top of the drying chamber through the support member 34, and the gypsum board 40 is taken out from the discharge port 12 by using an external tool.

[0049] In the gypsum board drying device of this technical solution, hot air required for drying work is introduced into the drying chamber 10 through the air duct 13, the gypsum board 40 is conveyed to the bottom of the drying chamber through the feeding assembly 20, and the lifting assembly 30 drives the gypsum board 40 to pass through the drying chamber from bottom to top to complete the drying work, ensuring the continuity of the drying work of the gypsum board 40 and saving drying time and drying space.

[0050] As shown in Figure 1 , Figure 2 the drying chamber 10 is set as a bottom preheating section, a middle drying section, and a top cooling section; the air duct 13 is arranged corresponding to the three sections of the bottom preheating section, the middle drying section, and the top cooling section of the drying chamber 10.

[0051] In the gypsum board drying device of this technical solution, according to the characteristic that hot air moves upward when using hot air drying, the feeding port 11 is arranged at the bottom of the drying chamber 10, the discharge port 12 is arranged at the top of the drying chamber 10, and a situation where the temperature is low at the bottom, high in the middle, and second highest at the top is formed inside the drying chamber 10. During the process of the gypsum board 40 being lifted upward, the preheating, drying, and cooling processes are sequentially completed through the bottom preheating section, the middle drying section, and the top cooling section, matching the drying characteristics of the gypsum board 40 and ensuring the drying and forming effect of the gypsum board 40.

[0052] As shown in Figure 1As shown, the lifting assembly 30 further includes a driving member 33 disposed outside the drying chamber 10. In this embodiment, the driving member 33 can be set as a motor. The driving member 33 penetrates through the side wall of the drying chamber 10 and is connected to one group of the second rollers 31. The setting of the driving member 33 provides power for the rotation of the second roller 31. At the same time, the driving member 33 is assembled outside the drying chamber 10 to avoid the high temperature inside the drying chamber 10 from affecting the working performance of the driving member 33.

[0053] As Figure 3 、 Figure 4 As shown, the support member 34 includes a housing 341. A groove 342 is provided inside the housing 341. The open end of the groove 342 is the end of the housing 341 away from the lifting belt 32. Two sets of shielding members are provided inside the groove 342. The shielding member includes a leaf spring 343. The movable end of the leaf spring 343 is connected to a heat-resistant belt 344. The movable end of the heat-resistant belt 344 penetrates through the open end of the groove 342 and is connected to a side plate 345. Permanent magnets A 346 and permanent magnets B 347 are respectively provided on the side plates 345 of the two lifting assemblies 30. The movable end polarities of the permanent magnets A 346 and the permanent magnets B 347 are inconsistent. In this embodiment, the permanent magnets A 346 and the permanent magnets B 347 specifically select appropriate permanent magnet types according to the drying temperature inside the drying chamber 10 to avoid the permanent magnets from failing during use.

[0054] When the housing 341 moves to the bottom of the drying chamber, specifically when the housing 341 contacts the lower end surface of the gypsum board 40 and the housing 341 passes over the conveyor belt 22, the permanent magnets A 346 and the permanent magnets B 347 attract each other and adsorb, and at the same time drive the heat-resistant belt 344 to extend out of the groove 342. The two heat-resistant belts 344 and the two housings 341 form a matrix structure to cover the edges of the gypsum board 40. At this time, the leaf spring 343 is stretched. When the side plate 345 moves to face the top wall, side wall, and bottom wall of the drying chamber 10, the distance between the permanent magnets A 346 and the permanent magnets B 347 increases. Under the action of the leaf spring 343, the heat-resistant belt 344 drives the side plate 345 to return to the initial state.

[0055] In the gypsum board drying device of this technical solution, a shielding member is added. The heat-resistant belts 344 in the two shielding members and the two housings 341 form a matrix structure to shield the edges of the gypsum board 40, slowing down the drying speed of the edges. To a certain extent, it solves the problem in the prior art that the drying speeds of the four sides and the center of the gypsum board are different (the drying speed of the four sides is faster), which may cause cracking or bulging phenomena.

[0056] As Figure 3 As shown, the ends of the two side plates 345 located inside the same housing 341 are connected to form a support plate to ensure the synchronization of the movement of the two shielding members.

[0057] In the present technical solution, the side plate 345 is used to support the edge of the gypsum board 40 and drive the gypsum board 40 to move upward through the drying chamber to complete the drying work. There is a problem that the middle part of the gypsum board 40 has a tendency to collapse downward under the action of gravity, which affects the quality of the gypsum board 40. In this regard, as Figure 3 and Figure 5 shown, an expansion rod 348 is provided between the middle part of the support plate and the groove body 342; with the setting of the expansion rod 348, when the permanent magnet A 346 and the permanent magnet B 347 drive the side plate 345 to move, the expansion rod 348 synchronously extends or contracts, so that the side plate 345 remains in a horizontal state, and the side plate 345 maintains a certain height to support the middle part of the gypsum board 40, reducing the tendency of the middle part of the gypsum board 40 to collapse downward under the action of gravity and ensuring the finished product quality of the gypsum board 40.

[0058] At the same time, in the gypsum board drying device of the present technical solution, the gypsum board 40 moves upward through the drying chamber to complete the drying work, and hot air is used as the drying source. During the drying process, the hot air moves upward, giving an upward pressure to the middle part of the gypsum board 40 to a certain extent and slowing down the tendency of the middle part of the gypsum board 40 to collapse downward.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
