DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figure 1-3 As shown, the utility model proposes a silicon carbide ceramic support plate drying device, the rotating assembly 4 includes a driving member 41 and a rotating member 42 driven by the driving member 41 to drive multiple trays 5 to rotate synchronously. The driving member 41 includes a motor 411 connected to the drying box 1; the driving end of the motor 411 penetrates the drying box 1 and is connected to the top plate 412; multiple placement racks 3 are provided with through slots 301; the rotating member 42 includes a support plate 421 slidably connected to the multiple placement racks 3 in a one-to-one correspondence; the trays 5 are movably arranged on the support plates 421 in a one-to-one correspondence; the upper ends of multiple support plates 421 are connected to connecting columns 1 423; the uppermost connecting column 1 423 is connected to the top plate 412, and the upper ends of the remaining connecting columns 1 423 are connected to connecting plates 424; multiple connecting plates 424 are connected to the upper adjacent support plates 421 through connecting columns 2 425; the connecting columns 2 425 are arranged in the through slots 301. The driving member 41 drives the rotating member 42 to drive the multiple trays 5 to rotate synchronously, so that the ceramics on the multiple trays 5 can be evenly heated, avoiding the uneven heat distribution in the drying box 1, which causes the ceramics to crack due to different degrees of drying in different parts, affecting the ceramic output rate. In addition, the component is arranged on the placement rack 3, which improves the stability of the component and avoids the situation where the ceramics fall over and break due to shaking during rotation. At the same time, the component does not block the placement space above the tray 5, nor does it hinder the removal of the tray 5. Only one set of motors 411 can drive multiple trays 5 to rotate synchronously, which also greatly reduces energy consumption.

[0022] Further, an annular groove 302 is provided on the placement rack 3; a plurality of balls 422 arranged in the annular groove 302 are hinged at the lower end of the support plate 421, and the balls 422 roll in the annular groove 302 to make the support plate 421 slide on the placement rack 3. The friction between the support plate 421 and the corresponding placement rack 3 is reduced, so that the slide of the support plate 421 on the placement rack 3 is smoother, and the slide of the support plate 421 is prevented from being blocked.

[0023] Embodiment 2

[0024] like Figure 4 As shown, the silicon carbide ceramic support plate drying device proposed by the utility model, compared with the first embodiment, this embodiment also includes: two groups of blowing components 6 are symmetrically arranged about the drying box 1. The air blown by the blowing components 6 has a larger range, thereby making the air in the drying box 1 circulate more quickly.

[0025] Further explanation, a gear ring is provided at the side wall of the top plate 412; the blowing assembly 6 includes a gear 61 meshingly connected with the gear ring on the top plate 412; a connecting rod 62 is connected to the lower end of the gear 61; a plurality of fan blades 63 are connected to the connecting rod 62, and are also rotatably connected to a plurality of connecting blocks 64 provided on the drying box 1. The driving member 41 drives the plurality of fan blades 63 to rotate synchronously and blow air, which can accelerate the air circulation in the drying box 1, so that the heat emitted by the heating mechanism 2 is more quickly transmitted to the drying box 1, avoiding a large difference in the degree of drying of the ceramics due to excessive concentration of the heat source, and improving the drying efficiency of the ceramics.

[0026] The working principle of the utility model is as follows: when drying, first place the ceramic on the tray 5, then turn on the heating mechanism 2 to heat and dry the ceramic. At this time, start the motor 411, the motor 411 drives the top plate 412 to rotate, thereby driving the support plate 421 to rotate, and the ball 422 rolls in the annular groove 302, so that the support plate 421 slides on the placement rack 3. Make the sliding of the support plate 421 on the placement rack 3 smoother, and avoid the sliding of the support plate 421 being blocked. The driving member 41 drives the rotating member 42 to drive multiple trays 5 to rotate synchronously, so that the ceramics on the multiple trays 5 can be evenly heated, and avoid uneven heat distribution in the drying box 1, which causes the ceramics to crack due to different degrees of drying in different parts, affecting the ceramic output rate. The rotation of the top plate 412 simultaneously drives the gear 61 meshed with it to rotate, thereby driving the connecting rod 62 to rotate, and then driving the fan blade 63 to rotate, blowing air into the drying box 1. By driving the multiple groups of fan blades 63 to rotate synchronously and blow air through the driving member 41, the air circulation in the drying box 1 can be accelerated, and the heat emitted by the heating mechanism 2 can be transmitted to the drying box 1 more quickly, avoiding large differences in the degree of drying of the ceramics due to excessive concentration of heat sources, while improving the drying efficiency of the ceramics.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
