Description

Technical Field

[0001] The present invention relates to the field of air-cushion conveyors, and particularly to an end-sealing device for an upper and lower integrated air chamber of a fully enclosed air-cushion conveyor. Background Art

[0002] In traditional fully enclosed air-cushion conveyors, it is necessary to separately design upper and lower air chambers, and the upper and lower air chambers are in a separately separated state. In order to ensure airtightness, sealing plates are respectively added to the upper and lower air chambers, which is labor-consuming and material-consuming, and also increases the space required for installation.

[0003] In order to simplify the structure and reduce energy consumption, the upper and lower air chambers can be combined to obtain an upper and lower integrated air chamber. The biggest problem with the upper and lower integrated air-cushion conveyor is the sealing at the end. Since the return conveyor belt passes through the inside of the air chamber, sealing has become the biggest problem. If there is no effective sealing measure at the end of the air chamber, a large amount of compressed air inside the air chamber will leak, resulting in the inability to form an effective air film between the conveyor belt and the pan groove plate, and thus the air-cushion conveyor cannot work properly and needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide an end-sealing device for an upper and lower integrated air chamber of a fully enclosed air-cushion conveyor, which performs movable sealing at the end of the upper and lower integrated air chamber, does not affect the operation of the return part of the conveyor belt, and improves the sealing effect.

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

[0006] An end-sealing device for an upper and lower integrated air chamber of a fully enclosed air-cushion conveyor, comprising: a box body, a conveyor belt inlet trough body, and a floating sealing plate. The top of the box body is provided with a cover plate for sealing. The conveyor belt inlet trough body is horizontally arranged on the front end face of the box body. An inlet corresponding to the conveyor belt and extending to the inside of the box body is provided in the conveyor belt inlet trough body. An outlet is provided on the back of the box body. The conveyor belt is imported into the box body from the inlet and exported from the outlet. Sealing pads located above and / or below the conveyor belt are provided in the inlet. The box body is filled with particulate matter for sealing. The floating sealing plate is arranged inside the box body and sleeved on the conveyor belt, and the floating sealing plate fits with the inner wall of the box body to achieve sealing of the outlet.

[0007] Wherein, a flange is provided at the end of the conveyor belt inlet trough body, and a plugging plate is provided at the end of the upper and lower integrated air chamber. The flange is installed behind the plugging plate, and a square groove corresponding to the inlet is provided on the plugging plate.

[0008] Wherein, the particulate matter is plastic foam particles.

[0009] Wherein, clamping grooves corresponding to the conveyor belt are provided on the floating sealing plate.

[0010] Among them, an L-shaped bent plate extending backward above the conveyor belt is arranged on the floating sealing plate.

[0011] Among them, brushes are arranged above and below the conveyor belt behind the box body. Bolts connected to the brushes are arranged on the floating sealing plate, and through holes corresponding to the bolts are arranged on the back of the box body.

[0012] Beneficial effects of the present invention: A fully enclosed air cushion conveyor upper and lower integrated air chamber end sealing device specially designs a sealing cushion plate to reduce the airflow in the upper and lower integrated air chamber from entering the box body, and uses the particulate matter in the box body for flow resistance, increasing the resistance of the gas flowing in the box body. Finally, the floating sealing plate floats up and down, left and right with the conveyor belt and keeps fitting with the inner wall of the box body, improving the sealing effect of the outlet and ensuring the airtightness of the upper and lower integrated air chamber.

[0014] Figure 2 is Figure 1 A-A cross-sectional view of

[0015] Figure 3 is a schematic structural diagram of the upper and lower integrated air chamber. Detailed Embodiments

[0016] The following Figures 1 to 2 is combined with

[0017] such as Figure 1 and Figure 2 The fully enclosed air cushion conveyor upper and lower integrated air chamber end sealing device shown includes: a box body 1, a conveyor belt inlet trough body 4 and a floating sealing plate 7. In this embodiment, a cover plate 2 is arranged on the top of the box body 1 for sealing, and a sealing ring is arranged at the connection to avoid air leakage problems.

[0018] The conveyor belt inlet trough body 4 is horizontally arranged on the front end face of the box body 1. An inlet 11 corresponding to the conveyor belt is arranged in the conveyor belt inlet trough body 4 and extends to the inside of the box body 1. As Figure 2 and 3 shown, a flange 6 is arranged at the end of the conveyor belt inlet trough body 4, and a plugging plate 13 is arranged at the end of the upper and lower integrated air chamber 12. The flange 6 is installed behind the plugging plate 13. A square groove 14 corresponding to the inlet 11 is arranged on the plugging plate 13, which is beneficial for the introduction of the conveyor belt 5.

[0019] An outlet is arranged on the back of the box body 1. In this embodiment, the return part of the conveyor belt 5 is introduced into the box body 1 from the inlet and exported from the outlet. AsFigure 2 As shown, a sealing backing plate 10 located below the conveyor belt 5 is provided in the inlet 11. The sealing backing plate 10 is fixed by screws and is convenient to replace after wear, which can reduce the gap of the inlet 11 and reduce the airflow in the upper and lower integrated air chamber 12 from entering the box body 1.

[0020] The box body 1 is filled with particulate matter 3 for sealing. In this embodiment, the particulate matter 3 is plastic foam particles, which are light in self-weight and reduce the resistance of the conveyor belt 5. However, they can block the flow and increase the resistance of the gas flowing in the box body 1, which is beneficial to reducing the air leakage problem.

[0021] The floating sealing plate 7 is arranged in the box body 1 and sleeved on the conveyor belt 5. A clamping groove corresponding to the conveyor belt 5 is arranged on the floating sealing plate 7, so that the floating sealing plate 7 sways up and down, left and right along with the conveyor belt 5. Moreover, driven by the conveyor belt 5, the floating sealing plate 7 always keeps in contact with the inner wall of the box body 1 to achieve the sealing of the outlet.

[0022] In this embodiment, an L-shaped bent plate 15 extending backward above the conveyor belt 5 is arranged on the floating sealing plate 7 for guiding and limiting the particulate matter 3, so that the particulate matter 3 accumulates on the surface of the conveyor belt 5 to improve the airtightness. Brushes 8 located above and below the conveyor belt 5 are arranged at the rear of the box body 1 for cleaning the conveyor belt 5 and reducing the outflow of the particulate matter 3. Bolts 9 connected to the brushes 8 are arranged on the floating sealing plate 7, and through holes corresponding to the bolts 9 are arranged on the back of the box body 1. The diameter of the through holes is larger than the diameter of the bolts 9, so that the brushes 8 move up and down, left and right along with the floating sealing plate 7 to ensure the cleaning of the conveyor belt 5.
