Under the cooperation of the second turntable 8, the movable plate 9 can drive the blocking plate 11 to move downward, so that the blocking plate 11 drives the stirring rod 12 to move into the material. At the same time, under the cooperation of the transmission mechanism 5 and the first turntable 6, the telescopic rod 7 can drive the stirring rod 12 to rotate through the second turntable 8, so that the stirring rod 12 can stir the material, effectively preventing the situation where the preheating effect inside the material is not good, increasing the preheating effect of the device, and improving the quality of subsequent tableware manufacturing, thereby reducing the production cost. Under the action of the blocking plate 11, the material can be prevented from being sprayed out when the stirring rod 12 is stirring, thereby reducing the waste of material. A discharge plate 13 is installed in the inner cavity, and a limiting groove 14 is provided on the surface of the discharge plate 13. The number of the limiting grooves 14 is several, so that multiple materials can be preheated at the same time, which speeds up the preheating speed of the staff. A moving mechanism 15 is provided at the bottom of the discharge plate 13. Under the action of the moving mechanism 15, the preheated material can be pulled out of the shell 2, effectively preventing the staff's hands from being scalded due to the high air temperature inside the shell 2, improving the safety of the staff, and thus increasing the use effect of the device. A handle 16 is fixed on one side of the discharge plate 13, and the handle 16 can facilitate the staff to pull the discharge plate 13 out of the shell 2.

[0026] The transmission mechanism 5 includes a first belt pulley 51, the top of the first belt pulley 51 is fixedly connected to the bottom of the bevel gear set 4, the upper part of the first belt pulley 51 is slidably connected with a timing belt 52, one side of the timing belt 52 is slidably connected with a second belt pulley 53, one side of the second belt pulley 53 is provided with a third belt pulley 54, the bottom of the second belt pulley 53 is mutually transmission-connected with the bottom of the third belt pulley 54 through the timing belt 52, the bottoms of the first belt pulley 51, the second belt pulley 53 and the third belt pulley 54 are all fixedly connected to the top of the first turntable 6, with the cooperation of the stepping motor 3 and the bevel gear set 4, the first belt pulley 51 can drive the second belt pulley 53 to rotate through the timing belt 52, and the lower half of the second belt pulley 53 is transmission-connected with the third belt pulley 54 through the timing belt 52. The third belt pulley 54 can be rotated, so that the first turntable 6 drives the stirring rod 12 to rotate through the telescopic rod 7, so that the stirring rod 12 can stir the material, making the material preheated more comprehensively, effectively preventing the situation where the inside of the material cannot be heated, thereby increasing the use effect of the device.

[0027] The moving mechanism 15 includes a fixed plate 151, the bottom of which is fixedly connected to the top of the preheating component 1, a slide groove 152 is provided on the surface of the fixed plate 151, and a slider 153 is slidably connected to the surface of the slide groove 152, and the top of the slider 153 is fixedly connected to the bottom of the discharge plate 13, and the cross-sectional shape of the slider 153 is T-shaped. There are three sliders 153 and they are equidistantly designed along the surface of the fixed plate 151. With the cooperation of the fixed plate 151 and the slide groove 152, the staff can pull the discharge plate 13 out of the interior of the shell 2 through the slider 153, and can pull the discharge plate 13 out of the interior of the shell 2, which is convenient for the staff to take out the material box, effectively preventing the staff's hands from being scalded due to the excessive preheating temperature inside the shell 2, thereby improving the safety of the staff and increasing the use effect of the device.

After the discharge plate 13 is pulled out of the shell 2, the staff puts the prepared material into the limit groove 14, and then pushes the discharge plate 13 into the shell 2. The movable plate 9 moves downward through the hydraulic rod 10, and at the same time, the telescopic rod 7 is extended to make the second turntable 8 drive the stirring rod 12 to move downward through the blocking plate 11, so that the stirring rod 12 moves to the inside of the material, and the bottom of the blocking plate 11 and the top of the material box are fitted together to prevent the material from spilling when the stirring rod 12 is stirring. When the material starts to be heated, the staff steps With the cooperation of the motor 3 and the bevel gear set 4, the first belt pulley 51 can drive the second belt pulley 53 to rotate through the timing belt 52, so that the first belt pulley 51 and the first turntable 6 at the bottom of the second belt pulley 53 can rotate at the same time, and at the same time, the second belt pulley 53 drives the third belt pulley 54 to drive the first turntable 6 to rotate through the timing belt 52 of the lower part, and so on, so that multiple first turntables 6 can be rotated at the same time, and then the first turntable 6 drives the second turntable 8 to drive the stirring rod 12 to rotate through the telescopic rod 7, so as to stir the material and make the preheating more comprehensive. When the preheating is completed, the staff will pull out the discharge plate 13 and take out the material box inside the limit groove 14.
