[0019] The technical solutions 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 part of the embodiments of the present application, rather than all of the embodiments.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0021] like Figure 1-3As shown, a kiln safety device includes a furnace cabinet 1 and a lifting platform 2, and also includes a rotating shaft 3, a supporting plate 4 and a protective cover 6. The lifting platform 2 is rotatably connected to multiple rotating shafts 3, and the rotating shaft 3 is connected to a driving component for driving it to rotate. Multiple supporting plates 4 are evenly and fixedly arranged along the axial direction of the rotating shaft 3, and each supporting plate 4 is provided with multiple through holes 5. Multiple protective covers 6 are arranged in the furnace cabinet 1 for accommodating the supporting plates 4.

[0022] Specifically, multiple rotating shafts 3 synchronously fix and support multiple horizontally arranged support plates 4, multiple workpieces can be placed on the support plates 4, so that multiple workpieces can be heated at one time, and the support plates 4 enter the protective cover 6. When the support plates 4 are driven to rotate, the workpieces on the support plates 4 are prevented from falling due to the protection of the protective cover 6.

[0023] like Figure 3 As shown, the protective cover 6 is cylindrical with mesh holes on the surface, and the mesh holes allow heat to flow.

[0024] Preferably, the rotating shaft 3 is axially arranged vertically, and the bottom end of the rotating shaft 3 extends out of the bottom of the lifting platform 2 and is connected to the driving assembly.

[0025] Specifically, a plurality of support plates 4 are arranged along the axial direction of the rotating shaft 3 to achieve multi-layer storage of workpieces, and heat can also flow to the multi-layer workpieces.

[0026] like Figure 1 As shown, the driving assembly includes a transmission shaft 10, a first bevel gear 12 and a second bevel gear 13. There are four rotating shafts 3, and the bottom end of each rotating shaft 3 is fixedly provided with a second bevel gear 13. There are two transmission shafts 10, and both ends of the transmission shafts 10 are fixedly provided with a first bevel gear 12, and the first bevel gears 12 are meshed with the second bevel gears 13 one by one.

[0027] Specifically, the transmission shaft 10 connected to the two first bevel gears 12 can synchronously rotate the two first bevel gears 12, and at the same time, the two first bevel gears 12 can synchronously drive the two second bevel gears 13 to rotate. Therefore, the two transmission shafts 10 synchronously drive the four first bevel gears 12 to rotate, so that the four second bevel gears 13 rotate synchronously, and then the four rotating shafts 3 rotate.

[0028] like Figure 1 As shown, the driving assembly also includes a motor seat 8, a third bevel gear 9 and a shaft seat 11. The motor seat 8 is fixedly connected to the bottom of the lifting platform 2, and the motor 7 is fixedly installed on the motor seat 8. The output shaft of the motor 7 is provided with two third bevel gears 9. The shaft seat 11 is fixedly connected to the bottom of the lifting platform 2, and the transmission shaft 10 is rotationally connected to the shaft seat 11. The two third bevel gears 9 are meshed one by one with the two first bevel gears 12 on the same side.

[0029] Specifically, the motor 7 drives the third bevel gear 9 to rotate, the third bevel gear 9 meshes to drive the first bevel gear 12 to rotate, and the first bevel gear 12 meshes to drive the second bevel gear 13 to rotate.

[0030] like Figure 2 As shown, the support plate 4 is disc-shaped so that it will not touch the protective cover 6 when rotating, and at the same time can have a larger receiving area.

[0031] In the above structure, the workpiece to be heated is placed on the support plate 4. The multi-layer support plate 4 can hold multiple workpieces. Then the lifting platform 2 is driven to lift and enter the furnace cabinet 1. At this time, the support plate 4 enters the protective cover 6. During heating, if the workpiece to be heated is unevenly heated, the motor 7 is started to drive the third bevel gear 9 to find, and the third bevel gear 9 is engaged to drive the first bevel gear 12 to rotate. After the first bevel gear 12 rotates, the transmission shaft 10 rotates synchronously, which also causes the transmission shaft 10 to rotate synchronously away from the first bevel gear 12 at one end of the third bevel gear 9. At this time, the first bevel gears 12 on the two transmission shafts 10 rotate synchronously, and the engagement drives the second bevel gear 13 to find synchronously. After the second bevel gear 13 rotates, it drives the rotating shaft 3 to rotate, and then the support plate 4 rotates, so that the workpiece on the support plate 4 is heated more evenly. At the same time, during rotation, the support plate 4 is in the protective cover 6, and the protective cover 6 can protect the workpiece on the support plate 4 from falling.

[0032] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
