The electric heating wire 24 is located on the side of the fan blade 23 close to the shelf, and a protective net 25 is also provided between the electric heating wire 24 and the shelf. When the electric heating wire 24 is energized to generate heat, the multiple worms 20 respectively drive the multiple transmission shafts 21 to rotate by meshing with the multiple worm gears 22 during the rotation process, and the multiple fan blades 23 rotate accordingly to blow hot air toward the shelf. The protection net 25 is provided to separate the electric heating wire 24 from the shelf to prevent contact and burns between the electric heating wire 24 when the shelf is manually placed or taken out;

[0055] An adjusting mechanism is connected to the shelf and is used to drive the layer plate 8 to tilt. The adjusting mechanism includes a first reciprocating screw 16 fixedly connected to the bottom end of another column 7, a screw sleeve 17 screwed to the outside of the first reciprocating screw 16, a first gear 18 fixedly sleeved on the outside of the screw sleeve 17, and a tooth arc 19 fixedly connected to the top of the partition plate 5. The first gear 18 cooperates with the tooth arc 19. The outside of the screw sleeve 17 is rotatably connected to a support block, which is fixed to the top of the bottom plate 10. The outside of the first reciprocating screw 16 is sleeved with a guide sleeve, which is fixed to the top of the bottom plate 10. The column 7 and the layer plate 8 are connected by a connecting mechanism, which includes a connecting block 12 fixedly sleeved on the outside of the column 7, an active groove 13 radially penetrating the layer plate 8 and opened inside the layer plate 8, two slide grooves 14 opened inside the layer plate 8 along the length direction of the active groove 13, and two slide grooves 14 respectively fixed to the two ends of the connecting block 12 The two connecting shafts 15 on the side outer wall and the two slide grooves 14 are both connected to the movable groove 13 and symmetrically arranged on both sides of the movable groove 13. The two connecting shafts 15 are respectively abutted against the inside of the two slide grooves 14. During the rotation of the bottom plate 10, the first gear 18 is driven to perform an orbital motion around the axis of the bottom plate 10. When the first gear 18 is meshed with the tooth arc 19, the screw sleeve 17 is driven to rotate, thereby driving the first reciprocating screw 16 to move upward, and then driving the column 7 at the top of the first reciprocating screw 16 to move upward. The connecting shaft 15 can slide and rotate in the slide groove 14, driving the layer plate 8 to tilt. When the first gear 18 is meshed with the tooth arc 19 again next time, the first reciprocating screw 16 is driven to reset downward, and the layer plate 8 is reset accordingly, and then the layer plate 8 can automatically tilt during the rotation process, thereby effectively improving the uniformity of noodle drying on the top of the layer plate 8.

[0056] The lifting mechanism is installed below the driving disk 6 and is used to drive the shelf to move. The lifting mechanism includes a disk 26 arranged below the driving disk 6, four lifting columns 27 fixedly connected to the top of the disk 26, a driving sleeve 28 rotatably connected to the inner wall of the bottom of the box body 1, and a second reciprocating screw 29 screwed inside the driving sleeve 28. The top ends of the four lifting columns 27 extend to the inside of the four positioning holes 9 respectively. An annular groove 30 is provided at the bottom of the disk 26. A slider 31 is slidably connected to the inside of the annular groove 30 along its annular track. The top end of the second reciprocating screw 29 is fixedly connected to the bottom of the slider 31. When the driving disk 6 rotates, it passes through the positioning holes 9 and the lifting column 27. The connection function of the lowering column 27 drives the disc 26 to rotate synchronously, and the annular groove 30 rotates along the outside of the slider 31 accordingly, and the slider 31 remains stationary. When the driving sleeve 28 rotates, it drives the second reciprocating screw 29 to move upward, and then drives the four lifting columns 27 to move upward along the inside of their respective positioning holes 9 through the disc 26, and pushes out the roller 11 located inside the positioning hole 9, thereby separating the layer shelf from the positioning hole 9, thereby facilitating the removal of the layer shelf. When it is necessary to drive the lifting column 27 to reset, the driving sleeve 28 is continued to be driven to rotate, and the second reciprocating screw 29 moves downward accordingly, thereby driving the lifting column 27 on the top of the disc 26 to reset downward;

[0057] The driving mechanism is installed below the partition 5 and is used to drive the heating mechanism, the driving disk 6 and the lifting mechanism to operate. The driving mechanism includes a motor 32 installed on the inner wall of the bottom of the box body 1, a second gear 33 fixedly sleeved on the outside of the output shaft of the motor 32, a third gear 34 fixedly sleeved on the outside of the worm 20, a driving shaft 35 fixedly connected to the bottom of the driving disk 6, two fourth gears 36 fixedly sleeved on the outside of the output shaft of the motor 32 and the outside of the driving shaft 35, and a one-way gear 37 installed on the outside of the driving sleeve 28. The disc 26 is sleeved on the outside of the driving shaft 35. The diameter of the second gear 33 is larger than that of the third gear 34. The diameter of the second gear 33 is meshed with the third gear 34, and the two fourth gears 36 are meshed with each other, one of the fourth gears 36 is meshed with the one-way gear 37, and the output shaft thereof is driven to rotate by the starting motor 32, and the worm 20 is driven to rotate by the meshing effect between the second gear 33 and the third gear 34, and the drive shaft 35 is driven to rotate by the meshing effect between the two fourth gears 36, thereby driving the drive disk 6 and the shelf to rotate. At this time, the one-way gear 37 rotates accordingly, but the drive sleeve 28 does not rotate. When the control motor 32 drives its output shaft to rotate in the opposite direction, the drive sleeve 28 will rotate.

[0058] Working principle: When in use, the noodles are placed on the top of the layer plate 8. When placing the layer shelf, the four rollers 11 at the bottom of the bottom plate 10 are placed inside the positioning holes 9 of the driving disk 6. The output shaft of the motor 32 is driven to rotate by starting the motor 32. The worm 20 is driven to rotate by the meshing effect between the second gear 33 and the third gear 34. During the rotation process, the multiple worms 20 respectively drive the multiple transmission shafts 21 to rotate by the meshing effect between the multiple worm wheels 22. The multiple fan blades 23 rotate accordingly to blow hot air to the layer shelf. The drive shaft 35 is driven to rotate by the meshing effect between the two fourth gears 36, and then the drive disk 6 and the layer shelf are driven to rotate. During the rotation of the plate 10, the first gear 18 is driven to perform an orbital motion around the axis of the bottom plate 10. When the first gear 18 is meshed with the tooth arc 19, the screw sleeve 17 is driven to rotate, thereby driving the first reciprocating screw 16 to move upward, and then driving the column 7 at the top of the first reciprocating screw 16 to move upward. Through the sliding and rotatable function of the connecting shaft 15 in the slide groove 14, the layer plate 8 is driven to tilt. When the first gear 18 is re-engaged with the tooth arc 19 next time, the first reciprocating screw 16 is driven to reset downward, and the layer plate 8 is reset accordingly. Then, the layer plate 8 can automatically tilt during the rotation process, thereby effectively improving the uniformity of noodle drying on the top of the layer plate 8.

[0059] When the shelf needs to be removed, the control motor 32 drives its output shaft to rotate in the opposite direction, and the drive sleeve 28 rotates accordingly, driving the second reciprocating screw 29 to move upward, and then drives the four lifting columns 27 to move upward along the inside of their respective positioning holes 9 through the disc 26, pushing out the roller 11 located inside the positioning hole 9, and then separating the shelf from the positioning hole 9, thereby facilitating the removal of the shelf.
