Description

Technical Field

[0001] This utility model relates to the technical field of dual air cushion conveyors, specifically a dual air cushion conveyor. Background Technology

[0002] An air cushion conveyor is a device that uses air cushion technology for material transport. It is widely used in various industries, including coal, power, metallurgy, chemical, machinery, grain, light industry, ports, and building materials. Particularly in the port industry, air cushion conveyors are commonly used at bulk grain loading and unloading terminals, demonstrating excellent bulk material transport capabilities. Its basic principle is to form a thin but strong air film between the conveyor belt and the supporting surface using high-pressure air, thereby supporting the conveyor belt and the material on it, achieving continuous material transport.

[0003] Currently, the internal space of the air cushion in air cushion conveyors is designed as a connected, integrated structure. The large internal space of the air cushion expands, and when subjected to external pressure, such as the weight of the conveyor belt, the expansion of the air cushion causes deviations, resulting in an overall imbalance in the support provided by the air cushion to the conveyor belt, affecting the stability of the air cushion conveyor. Furthermore, dust on the conveyor belt surface can easily interfere with the operation of the air cushion conveyor, reducing its practicality. Utility Model Content

[0004] The purpose of this invention is to provide a double air cushion conveyor, which can make the air cushion conveyor more stable and can also clean the dust on the conveyor belt in a timely manner.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double air cushion conveyor, including a base, with conveying baffles on opposite sides of the top of the base, two conveying baffles, and conveying rollers at opposite ends between the two conveying baffles, two conveying rollers, and a conveyor belt wrapped between the two conveying rollers. A servo motor is mounted on one end of each conveying baffle via a motor frame, and the output end of the servo motor is connected to one end of the conveying roller via a coupling. Two support partitions are provided between the two conveying baffles, and a balancing air cushion is provided on the side of each support partition that is far from the support partition, two balancing air cushions, with the side of the balancing air cushion far from the support partition in contact with the inner surface of the conveyor belt.

[0006] Preferably, the balancing air cushion consists of an air cushion layer, connecting adhesive dots, air bladders, balancing channels, and inflation holes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, a double air cushion conveyor includes a base 1. Two conveying baffles 2 are provided on opposite sides of the top of the base 1. Two conveying rollers 81 are provided at opposite ends between the two conveying baffles 2. A conveyor belt 7 is wrapped between the two conveying rollers 81. A servo motor 8 is mounted on one end of each conveying baffle 2 via a motor frame. The output end of the servo motor 8 is connected to one end of each conveying roller 81 via a coupling. Two supporting partitions 3 are provided between the two conveying baffles 2. Two balancing air cushions 4 are provided on the side of each supporting partition 3 that is far from the supporting partitions 3. The side of the balancing air cushion 4 that is far from the supporting partitions 3 is fitted against the inner surface of the conveyor belt 7. The balancing air cushions 4 of the double air cushion conveyor provide flat expansion support for the conveyor belt 7, increasing the flatness and stability of the conveyor.

[0021] Specifically, the balancing air cushion 4 consists of an air cushion layer 41, connecting adhesive points 42, air bladders 43, a balancing channel 44, and an inflation hole 45. The air cushion layer 41 has two layers, and the edges of the two air cushion layers 41 are integrally connected. The sides of the two air cushion layers 41 that are close to each other are connected by connecting adhesive points 42. The two air cushion layers 41 are connected by connecting adhesive points 42 to form several connected air bladders 43. A balancing channel 44 is formed between two adjacent connecting adhesive points 42. An inflation hole 45 is provided on one side of the balancing air cushion 4. The inflation hole 45 is connected to the air bladders 43. Air is inflated into the air bladders 43 inside the air cushion layer 41 through the air outlet 45. The inflation is carried out through the balancing channel 44 between the connecting adhesive points 42, so that the air bladders 43 are connected and inflated. The balancing air cushion 4 is inflated and expanded in a balanced manner, and the balancing air cushion 4 and the conveyor belt 7 are flatter.

[0022] Furthermore, the connecting adhesive dots 42 are evenly distributed in a regular polygonal shape, and the airbags 43 are evenly arranged in a regular polygonal structure, so that the airbags 43 with multi-space structure inside the balancing air cushion 4 provide support and balance.

[0023] Furthermore, the inflation port 45 is connected to the inflation pump 6 via the connecting pipe 5. The connecting pipe 5 is equipped with a control valve. The inflation pump 6 inflates the airbags 43 between the air cushion layers 41 through the air outlet 45 via the connecting pipe 5. After inflation, the control valve on the connecting pipe 5 is closed, making it convenient to inflate the balance air cushion 4.

[0024] Furthermore, a limiting strip 10 is provided on the side of the balancing air cushion 4 away from the supporting partition 3. The two sides of the limiting strip 10 are set with a recessed groove structure. A limiting groove is provided on the side of the conveyor belt 7 close to the balancing air cushion 4. The limiting strip 10 is slidably disposed inside the limiting groove. The conveyor belt 7 is conveyed at the upper limit of the limiting strip 10 of the balancing air cushion 4 through the limiting groove. The structure between the conveyor belt 7 and the balancing air cushion 4 is compact.

[0025] Furthermore, a cleaning plate 11 is provided between the two conveying baffles 2 below the conveyor belt 7. A dust collector is provided on the top of the cleaning plate 11. The dust collector can be a dust removal cleaning brush or a dust removal suction port. The dust removal suction port is connected to the dust removal bag through a suction pipe. The dust removal bag is connected to the dust removal fan through a dust removal pipe. The dust on the conveying surface of the conveyor belt 7 is cleaned by the cleaning brush or the dust removal suction port. A support base 9 is provided at the bottom of the machine base 1, and the machine base 1 is stably supported.

[0026] Furthermore, the top of the two conveyor baffles 2 is higher than the top of the conveyor belt 7, and the conveyor baffles 2 are higher than the conveyor belt 7, which can prevent the materials conveyed on the conveyor belt 7 from falling off.

[0027] The usage method of this embodiment is as follows: the servo motor 8 drives the conveyor roller 81 to rotate, and the conveyor belt 7 wrapped around the conveyor roller 81 and the balance air cushion 4 continuously transports between the two conveyor baffles 2. The conveyor belt 7 is conveyed at the upper limit of the limit strip 10 of the balance air cushion 4 through the limit slot. The air pump 6 inflates the airbags 43 between the air cushion layers 41 through the air outlet 45 through the connecting pipe 5. The inflation flows through the balance channel 44 between the connecting glue points 42, so that the airbags 43 are connected and inflated. The balance air cushion 4 is inflated and expanded in balance, that is, the balance air cushion 4 on the support baffle 3 provides overall support and balance for the conveyor belt 7. After inflation, the control valve on the connecting pipe 5 is closed. During the conveying operation, the conveyor belt 7 passes through the cleaning plate 11 below to perform cleaning treatment such as dust removal on the conveying surface of the conveyor belt 7.
