Description

Technical Field

[0001] The present invention relates to the field of air cushion conveyors, and in particular to a fully enclosed double-air cushion upper and lower integrated air cushion conveyor. Background Art

[0002] In traditional fully enclosed air cushion conveyors, the upper and lower air chambers need to be designed separately. The upper and lower air chambers are in a separate state. In order to ensure airtightness, sealing plates are added to the upper and lower air chambers respectively, which is labor-intensive and material-intensive and increases the space required for installation.

[0003] In addition, the upper and lower air chambers have complex structures and large volumes, and their overall rigidity and strength are poor, resulting in a short service life and increased operation and maintenance costs. The sealing structure has poor stability and is prone to air leakage, which increases energy consumption and needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide a fully enclosed double-air cushion upper and lower integrated air cushion conveyor, which simplifies the structure, reduces the cost, and ensures air tightness and structural stability.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A fully enclosed double-air-cushion upper and lower integrated air-cushion conveyor, comprising: an integrated air chamber, a bracket, a tail cover, and a head sealing cover, wherein the bracket is arranged at the bottom of the integrated air chamber for support, and the tail cover and the head sealing cover are arranged at both ends of the integrated air chamber, and a conveyor belt passing through the integrated air chamber and extending into the head sealing cover is arranged in the tail cover, and the integrated air chamber comprises an upper plate trough plate, a lower plate trough plate, a cover shell and two parallel and spaced side plates, the upper plate trough plate is arranged between the two side plates and is located below the outgoing part of the conveyor belt, the cover shell is located above the outgoing part of the conveyor belt, and the two side edges of the cover shell are respectively connected to the outer side surfaces of the corresponding side plates, the lower plate trough plate is arranged between the two side plates and is located below the return part of the conveyor belt, and a bottom plate located below the lower plate trough plate is arranged between the two side plates.

[0007] Wherein, transmission rollers corresponding to the conveyor belts are respectively arranged in the tail cover and the head sealing cover.

[0008] The integrated air chamber adopts a segmented structure, including several sub-air chambers connected in sequence, and adjacent sub-air chambers are connected by flanges.

[0009] Wherein, the upper plate trough plate and the lower plate trough plate are respectively provided with air holes.

[0010] The cross section of the upper plate trough is an arc-shaped structure with a concave middle portion.

[0011] It also includes an air supply pipeline, which is located below the bottom plate and extends along the length of the air chamber. Air pipes connected to the air supply pipeline are arranged at intervals on the bottom plate, and valves are respectively provided on the air pipes.

[0012] The beneficial effects of the present invention are as follows: a fully enclosed double-air-cushion upper and lower integrated air-cushion conveyor, in which the upper plate trough plate and the lower plate trough plate share side plates to form an upper and lower integrated double-air-cushion structure, which simplifies the structure, saves material, manufacturing and installation costs, reduces deadweight, can enhance overall strength and rigidity, effectively reduce volume, save installation space, and make its structure more compact and reasonable.

[0015] The following combination Figures 1 to 2 The technical solution of the present invention is further illustrated by specific embodiments.

[0016] like Figure 1 and Figure 2 The fully enclosed double-air-cushion upper and lower integrated air-cushion conveyor shown includes: an air supply pipe 17, an integrated air chamber 1, a bracket 6, a tail cover 2, and a head sealing cover 4. In this embodiment, the integrated air chamber 1 extends upward from the bottom, and the bracket 6 is arranged at the bottom of the integrated air chamber 1 for support, and the structure is stable.

[0017] The tail hood 2 and head sealing hood 4 are located at both ends of the integrated air chamber 1 to enhance airtightness. A conveyor belt 3 is installed in the tail hood 2, extending through the integrated air chamber 1 and into the head sealing hood 4. A hopper is provided on the tail hood 2 to facilitate material delivery, which is then conveyed via the conveyor belt 3. Drive rollers 5 corresponding to the conveyor belts 3 are installed in each of the tail hood 2 and head sealing hood 4, respectively, and are driven by motors.

[0018] like Figure 2 As shown, the integrated air chamber 1 includes an upper plate trough 13, a lower plate trough 15, a housing 11, and two parallel and spaced side plates 12. The upper plate trough 13 is disposed between the two side plates 12 and below the upper portion of the conveyor belt 3. Air holes are provided on the upper plate trough 13, forming an air cushion through the upper plate trough 13 to support the bottom of the conveyor belt's outward section 31. The cross-section of the upper plate trough 13 is an arc-shaped structure with a concave center to accommodate deformation of the conveyor belt's outward section 31 after blanking.

[0019] In this embodiment, the cover 11 is located above the conveyor belt outward section 31, and the two side edges of the cover 11 are respectively connected to the outer side surfaces of the corresponding side panels 12 to enhance the protective effect. The lower plate trough 15 is set between the two side panels 12 and located below the conveyor belt return section 32. The lower plate trough 15 is provided with air holes, and an air cushion is formed by the lower plate trough 15 to support the bottom of the conveyor belt return section 32, reducing running resistance and friction problems. Figure 2 As shown, the upper plate trough plate 13 and the lower plate trough plate 15 share two side plates 12 to form an upper and lower integrated double air cushion structure, which simplifies the structure, saves material, manufacturing and installation costs, and reduces dead weight.

[0020] A bottom plate 19 is located between the two side panels 12, below the lower plate trough plate 13, to enhance sealing and structural strength. The air supply pipe 17 is located below the bottom plate 19 and extends along the length of the air chamber 1. Air pipes 18 connected to the air supply pipe 17 are spaced apart on the bottom plate 19. Air is supplied to the top of the bottom plate 19 through the air pipes 18. The airflow escapes upward through the lower plate trough plate 15, forming an air cushion corresponding to the return section 32 of the conveyor belt. The airflow escaping from both sides of the return section 32 then escapes upward through the upper plate trough plate 13, forming an air cushion corresponding to the forward section 31 of the conveyor belt. Valves 16 are provided on each of the air pipes 18 to facilitate regulating the air supply flow rate at different sections, providing good adaptability.

[0021] In this embodiment, the integrated air chamber 1 adopts a segmented structure, including several sub-air chambers connected in sequence, and flanges 14 are provided between adjacent sub-air chambers to connect them, so as to facilitate changing the length of the integrated air chamber 1 to adapt to the on-site installation environment.

[0022] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
