[0027] At present, microwave drying machines are mainly used for drying food and pharmaceutical raw materials, and drying materials such as powder, granules, flakes, strips, plates, and small blanks. The material conveying device structure mainly utilizes a conveyor belt, one end of which is fixedly connected to a driving roller, and the other end of the tensioning shaft is connected to the bracket. The middle conveyor belt is hung on the middle passive roller.

[0028] The conveyor belt type conveying device is not convenient for transporting stone plates with large weight and size, and the installation and maintenance of the conveyor belt are relatively difficult, resulting in increased transportation costs and small carrying capacity. Therefore, a conveying device is proposed for transporting stone plates in a microwave drying machine.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a plate conveying device for a microwave drying machine includes a conveying line frame 1, a roller shaft 2 and a driving mechanism.

[0031] A plurality of rollers 2 are arranged on the upper part of the conveyor line frame 1. The rollers 2 are evenly distributed along the conveying direction of the conveyor line frame 1. The spacing between the rollers 2 is 250 mm. Vertical bearing seats 4 are arranged at both ends of the rollers 2. The rollers 2 are installed on the conveyor line frame 1 through the vertical bearing seats 4. A plurality of plastic rollers 21 and a plurality of plastic spacers 22 are arranged on the outer side of the rollers 2. Adjacent plastic rollers 21 are separated by the plastic spacers 22. The outer diameter of the plastic rollers 21 is larger than the plastic spacers 22. The plastic rollers 21 are in contact with the plate through the plastic rollers 21 and support the plate.

[0032] The driving mechanism includes a reduction motor 3, which is arranged at the lower part of the conveyor frame 1, and the reduction motor 3 is located at the starting end of the conveyor frame. The output end of the reduction motor 3 is provided with an output sprocket 31, and the end of the roller shaft 2 located at the starting end of the conveyor frame 1 is provided with a first sprocket 23. The output sprocket 31 and the first sprocket 23 are connected by a long chain 32, which serves as a power roller shaft;

[0033] The ends of the rollers 2 located at the starting and ending ends of the conveyor line frame 1 are provided with second sprockets 24 (i.e., the first roller 2 and the last roller 2), and the ends of the remaining rollers 2 are provided with double-row sprockets 25, and the double-row sprockets 25 are connected to the adjacent double-row sprockets 25 or the second sprockets 24 through short chains 26;

[0034] The reduction motor 3 is used to drive the first roller shaft 2 to rotate via a long chain 32 , and the roller shafts 2 are connected via a double-row sprocket 25 and a short chain 26 .

[0035] Anti-leakage mounting side plates 51 are provided on both sides of the upper part of the conveyor line frame 1. A plurality of holes are opened on the anti-leakage mounting side plates 51 for the roller shaft 2 to pass through. The vertical bearing seat 4 is located on the outer side of the anti-leakage mounting side plates 51 for easy maintenance of the outer vertical bearing seat 4. An anti-leakage mounting bottom plate 52 is provided at the bottom of the anti-leakage mounting side plates 51.

[0036] Preferably, a stopper 6 is provided at the end of the conveyor line frame 1 to prevent the plate from falling. There may be multiple stoppers 6 installed on the conveyor line frame 1 .

[0037] Preferably, a plurality of guide wheels 7 are provided on both sides of the starting end of the conveyor line frame 1 for guiding and conveying the plates.

[0038] Preferably, a sensor 8 is provided at the starting end of the conveyor line frame 1. The sensor 8 can be an infrared sensor. The sensor 8 is used to detect whether the material enters the microwave dryer (i.e., whether it leaves the starting end of the conveyor line frame 1). The sensor 8 can be connected to an external system to record the number of conveyed stone slabs.

[0039] When in use, the reduction motor 3 is started, and the reduction motor 3 drives the conveying sprocket 31 to rotate, so as to drive the long chain 32 to rotate, thereby driving the first roller 2 to rotate, and the first roller 2 drives the next roller 2 to rotate through the short chain 26, so that all rollers 2 rotate, thereby completing the power transmission of the entire conveyor line;

[0040] The stone slab is placed on the roller 2 at the starting end of the conveyor line for conveying, and the roller 2 drives the stone slab to move into the microwave cavity of the microwave dryer to absorb microwave heating. After heating, the roller 2 drives the stone slab to move to the end of the conveyor line and is blocked by the block 6 to complete the conveying.
