Technical Field

The invention relates to the field of air cushion conveyors, in particular to an upper and lower integrated air chamber end sealing device of a fully-closed air cushion conveyor.

Background

In the traditional totally-enclosed air cushion conveyor, an upper air chamber and a lower air chamber need to be designed independently, the upper air chamber and the lower air chamber are in an independent separated state, and in order to ensure air tightness, sealing plates are respectively added to the upper air chamber and the lower air chamber, so that labor and material are wasted, and the space required by installation is increased.

In order to simplify the structure and reduce the energy consumption, the upper air chamber and the lower air chamber can be combined to obtain an upper integrated air chamber and a lower integrated air chamber, the biggest problem of the upper integrated air cushion conveyor and the lower integrated air cushion conveyor is the sealing of the end parts, and the return conveyor belt penetrates through the air chambers, so the sealing becomes the biggest problem. If the end part of the air chamber is not provided with an effective sealing measure, compressed air in the air chamber can be leaked in a large amount, so that an effective air film cannot be formed between the conveying belt and the disc trough plate, and the air cushion conveyor cannot work normally and needs to be improved.

The invention aims to provide an upper and lower integrated air chamber end sealing device of a totally-enclosed air cushion conveyor, which is used for movably sealing the end part of an upper and lower integrated air chamber, does not influence the operation of a return part of a conveying belt, and improves the sealing effect.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides an upper and lower integral type air chamber tip sealing device of totally closed air cushion conveyer, includes: the leading-in cell body of box, conveyer belt and floating seal plate, the box top is provided with the apron and seals, the leading-in cell body of conveyer belt transversely sets up the preceding terminal surface at the box, be provided with the import that corresponds with the conveyer belt that extends to the box inboard in the leading-in cell body of conveyer belt, the box back is provided with the export, the leading-in box of conveyer belt follow import to derive from the export, be provided with the sealed backing plate that is located conveyer belt top and/or below in the import, it seals to have the particulate matter to fill in the box, floating seal plate sets up in the box and overlaps establishes on the conveyer belt, floating seal plate and the laminating of box inner wall realize.

The end part of the conveying belt lead-in groove is provided with a flange, the end part of the upper-lower integrated air chamber is provided with a plugging plate, the flange is arranged behind the plugging plate, and the plugging plate is provided with a square groove corresponding to an inlet.

Wherein the particulate matter is plastic foam particles.

Wherein, the floating sealing plate is provided with a clamping groove corresponding to the conveying belt.

Wherein, an L-shaped bent plate which extends backwards to the upper part of the conveying belt is arranged on the floating sealing plate.

The rear of the box body is provided with brushes positioned above and below the conveying belt, the floating sealing plate is provided with a bolt connected with the brushes, and the back of the box body is provided with a through hole corresponding to the bolt.

The invention has the beneficial effects that: the utility model provides an upper and lower integral type air chamber tip sealing device of totally closed air cushion conveyor, the sealed backing plate of having designed very much, the air current that reduces in the upper and lower integral type air chamber gets into the box to utilize the particulate matter in the box to carry out the choked flow, increase the resistance of gaseous flow in the box, float about the conveyer belt through floating seal plate at last, and keep with the laminating of box inner wall, promote the sealed effect of export, ensure the gas tightness of upper and lower integral type air chamber.
