[0027] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0028] like Figure 1-5 As shown, the utility model comprises a frame 1, a buffer plate installed on the frame 1 and located below the conveyor belt 2, and an air supply mechanism for supplying air between the buffer plate and the conveyor belt 2. The air supply mechanism supplies air to form an air film between the buffer plate and the conveyor belt 2. The air film has a strong buffering capacity and is fluid, so that the buffering force on the conveyor belt 2 is more evenly distributed, thereby improving the reliability of buffering.

[0029] The air supply mechanism includes a transmission roller 3 located below the conveyor belt 2 and the roller surface is in contact with the conveyor belt 2, and an air compressor 4 connected to the transmission roller 3. The transmission roller 3 is arranged along the width direction of the conveyor belt 2. Both ends of the transmission roller 3 are rotatably mounted on the frame 1, the input shaft of the air compressor 4 is connected to one end of the transmission roller 3, a plurality of air outlets 5 are arranged at the bottom of the buffer plate, and the air outlet of the air compressor 4 is connected to the air outlet 5. Specifically, the air outlet of the air compressor 4 is connected to each air outlet 5 through an air hose. The transmission roller 3 rotates continuously with the continuous transmission of the conveyor belt 2. The rotation of the transmission roller 3 drives the air compressor 4 to work and delivers the generated compressed air to the air outlet 5. The air is discharged through each air outlet 5 to form a layer of air film between the buffer plate and the conveyor belt 2.

[0030] In this embodiment, the input shaft of the air compressor 4 is connected to one end of the transmission roller 3 through a coupling, which increases the stability of the connection between the air compressor 4 and the transmission roller 3. The air compressor 4 is a piston air compressor. The air outlet of the air compressor 4 is connected to a plurality of air hoses through an air supply pipe, and each air hose is connected to a corresponding air outlet 5. The plurality of air outlets 5 are evenly distributed at the bottom of the buffer plate.

[0031] In this embodiment, the driving roller 3 is located behind the buffer plate, and the front-to-back direction is defined by the conveying direction of the conveying belt 2, and the conveying direction of the conveying belt 2 is from front to back.

[0032] The buffer plate includes a concave arc plate 6 and a buffer layer 7 covering the upper surface of the arc plate 6, and the buffer layer 7 is made of rubber. The arc plate 6 includes a bottom plate 61 and side plates 62 respectively located on both sides of the bottom plate 61 and hinged to the bottom plate 61. The arc plate 6 is connected to the frame 1 through a lifting device, and the lifting device includes two groups of supporting mechanisms, and the two groups of supporting mechanisms respectively support the two ends of the arc plate 6, and each group of supporting mechanisms includes a lower channel steel 12 arranged along the width direction of the frame 1 and inverted, and the upper channel steel 10 is opened upward and located above the lower channel steel 12. Rubber pads 11 for supporting the upper channel steel 10 are respectively placed at both ends of the lower channel steel 12, and the lower channel steel 12, the rubber pads 11 and the upper channel steel 10 are connected through bolts. The bottom plate 61 is welded and fixed to the upper channel steel 10. Further, connecting plates 13 are fixed at both ends of the lower channel steel 12, and each connecting plate 13 is connected to the frame 1 by bolts.

[0033] A plurality of V-shaped rollers 14 are installed on the bottom surface of the upper channel steel 10, and a track 15 for the V-shaped rollers 14 to travel is installed on the top surface of the lower channel steel 12, and limit blocks 16 are provided at both ends of the track 15. When the rubber pad 11 supports the upper channel steel 10, the V-shaped rollers 14 do not contact the track 15. When the rubber pad 11 is removed, the upper channel steel 10 falls and the V-shaped rollers 14 contact the track 15. After the rubber pad 11 is removed, the upper channel steel 10 can be dragged to achieve displacement of the arc plate 6, which is convenient for inspection and maintenance.

[0035] During specific operation, as the conveyor belt 2 is continuously driven, the transmission roller 3 is driven to rotate continuously. The rotation of the transmission roller 3 drives the air compressor 4 to compress the air and transmit the compressed air to the air outlet 5. The air is discharged through each air outlet 5 to form an air film between the buffer plate and the conveyor belt 2. The air film has a strong buffering capacity and is fluid. The buffering force of the conveyor belt 2 is more evenly distributed, thereby improving the buffering stability.

[0036] The utility model has a simple structure. The conveyor belt 2 drives the driving roller 3 to rotate so that the air compressor 4 supplies air to between the buffer plate and the conveyor belt 2, and an air film is formed between the buffer plate and the conveyor belt 2, thereby enhancing the buffering effect. The air compressor 4 does not need to be powered by a power supply, thereby realizing unpowered air supply, saving energy and reducing consumption, and reducing production costs.
