Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to an upper and lower integrated air chamber structure of a double 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 air tightness, 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. The upper and lower air chambers have complex structures and large volumes, and the overall rigidity and strength are poor, resulting in a short service life, which increases the operation and maintenance costs. The sealing structure has poor stability and is prone to air leakage, which increases energy consumption.

[0003] In addition, due to factors such as long conveyor lines and unstable air supply, some air cushion conveyors cause frequent contact between the conveyor belt and the disc groove plate, which accelerates the wear of the conveyor belt and reduces its service life, which requires improvement. Summary of the invention

[0004] The object of the present invention is to provide an upper and lower integrated air chamber structure for a double air cushion conveyor, which simplifies the structure, reduces the cost, improves the stability, and reduces the wear of the conveyor belt.

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

[0006] A double air cushion conveyor upper and lower integrated air chamber structure, comprising: an upper plate groove plate, a lower plate groove plate and two side plates spaced parallel to each other, the upper plate groove plate is arranged between the two side plates, the lower plate groove plate is arranged between the two side plates and is located below the upper plate groove plate, a bottom plate is arranged between the two side plates and is located below the lower plate groove plate, the upper plate groove plate and the lower plate groove plate respectively comprise a ball, a first clamping plate and a second clamping plate, the first clamping plate is attached to the upper surface of the second clamping plate, the first clamping plate and the second clamping plate are provided with concentric first air holes, the ball is arranged between the first clamping plate and the second clamping plate, the top of the ball protrudes above the first clamping plate, the bottom of the ball protrudes below the second clamping plate, and the ball is provided with a plurality of radially extending second air holes.

[0007] Wherein, air pipe joints are arranged at intervals below the bottom plate.

[0008] Wherein, the bottom surface of the first clamping plate and the top surface of the second clamping plate are provided with spherical grooves corresponding to the balls.

[0009] Wherein, the balls are steel balls.

[0010] Wherein, the first clamping plate and the second clamping plate are fixed by welding or bolts.

[0011] Wherein, the cross section of the upper plate trough is an arc-shaped structure with a concave middle portion.

[0012] The beneficial effects of the present invention are as follows: a double air cushion conveyor with an integrated upper and lower air chamber structure, in which the upper plate trough plate and the lower plate trough plate share a side plate for sealing, and have a simple structure, good air tightness, and high structural stability, which is beneficial to reducing installation and operation and maintenance costs. An air cushion is formed by using the first air hole and the second air hole on the ball bearing to support the conveyor belt. When the conveyor belt contacts the upper plate trough plate or the lower plate trough plate due to an abnormality, the ball bearing is used to provide rolling support for the conveyor belt, thereby reducing the wear of the conveyor belt and extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the structure of the present invention;

[0014] Figure 2 yes Figure 1 A partial enlarged view of the middle and lower plate trough. DETAILED DESCRIPTION

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

[0016] like Figure 1 The double air cushion conveyor upper and lower integrated air chamber structure shown comprises: an upper plate groove plate 2, a lower plate groove plate 5 and two parallel side plates 3 spaced apart from each other. The upper plate groove plate 2 is arranged between the two side plates 3 to support the bottom surface of the conveyor belt outward portion 1. The cross section of the upper plate groove plate 2 is an arc-shaped structure with a concave middle portion to adapt to the deformation of the conveyor belt outward portion 1 after blanking.

[0017] The lower plate slot plate 5 is arranged between the two side plates 3 and below the upper plate slot plate 2 to support the bottom surface of the conveyor belt return portion 4. In this embodiment, the upper plate slot plate 2 and the lower plate slot plate 5 share the side plate 3 for sealing, forming an upper and lower integrated air chamber with a simple structure, good air tightness, and high structural stability, which is conducive to reducing installation and operation and maintenance costs.

[0018] A bottom plate 6 is provided between the two side plates 3 and is located below the lower plate groove plate 5 to form a sealing structure. In the present embodiment, an air pipe joint 12 is provided below the bottom plate 6 to facilitate connection with the air supply pipeline and input of compressed air to the top of the bottom plate 6, which is conducive to forming air cushions on the upper plate groove plate 2 and the lower plate groove plate 5 respectively.

[0019] like Figure 2 As shown, in this embodiment, the upper plate groove plate 2 and the lower plate groove plate 5 respectively include a ball 7, a first clamping plate 8 and a second clamping plate 10, the first clamping plate 8 is attached to the upper surface of the second clamping plate 10, and a double-layer structure is formed. The first clamping plate 8 and the second clamping plate 10 are fixed by welding or bolts, and the structure is firm.

[0020] The first clamping plate 8 and the second clamping plate 10 are provided with concentric first air holes 9, which are conducive to forming an air cushion. The ball 7 is arranged between the first clamping plate 8 and the second clamping plate 10. The bottom surface of the first clamping plate 8 and the top surface of the second clamping plate 10 are provided with spherical grooves corresponding to the ball 7 to position and roll the ball 7. The top of the ball 7 protrudes above the first clamping plate 8, and the bottom of the ball 7 protrudes below the second clamping plate. The ball 7 is provided with a plurality of radially extending second air holes 11. The first air holes 9 and the second air holes 11 are used to form an air cushion to support the conveyor belt.

[0021] In this embodiment, the ball bearings 7 are steel balls with low rolling friction. When the conveyor belt contacts the upper plate groove plate 2 or the lower plate groove plate 5 due to an abnormality, the ball bearings 7 can be used to provide rolling support for the conveyor belt, thereby reducing the wear of the conveyor belt and extending its service life.
