[0027] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals always represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0028] The following disclosure provides many different embodiments or examples for implementing different solutions of the present utility model.

[0029] Referring to Figures 1 to 4 As shown, in an embodiment of the present utility model, a feeding device for an air cushion belt conveyor includes a cover plate 1 located above the conveyor belt 100. A feeding port 11 is provided on the cover plate 1. Two guide plates 2 are rotatably provided inside the cover plate 1, and the two guide plates 2 are located on both sides of the feeding port 11 along the conveying direction of the conveyor belt 100.

[0030] A driving mechanism 3 is provided on the cover plate 1, and the driving mechanism 3 is connected to the guide plate 2 to drive the guide plate 2 to swing.

[0031] When the guide plate 2 rotates to the first posture, the guide plate 2 can block the materials splashed from the conveyor belt 100.

[0032] When the guide plate 2 swings to the second posture, the guide plate 2 does not block the materials conveyed by the conveyor belt 100 from passing below it.

[0033] When the intermediate feeding port 11 is operating, the guide plate 2 is in the first posture. When the intermediate feeding port 11 is not operating, the guide plate 2 is in the second posture. Based on this structure, the guide plate 2 is made more flexible and adapted to the intermediate feeding port 11.

[0034] Specifically, a mounting bracket 4 is provided inside the cover plate 1, and the guide plate 2 is hinged to the mounting bracket 4.

[0035] When the guide plate 2 is in the first posture, the end of the guide plate 2 far from the mounting bracket 4 can be in contact with or very close to the tape of the conveyor belt 100, thereby preventing the materials on the tape from splashing out.

[0036] When the guiding plate 2 is in the second posture, the end of the guiding plate 2 away from the mounting bracket 4 can be in contact with or very close to the cover plate 1. At this time, the guiding plate 2 does not obstruct the materials on the conveyor belt 100 from passing below it.

[0037] In this embodiment, the driving mechanism 3 includes a pull rod 31 movably arranged on the cover plate 1. The pull rod 31 is connected to the guiding plate 2, and pulling the pull rod 31 drives the guiding plate 2 to swing.

[0038] Generally, two pull rods 31 are arranged for one guiding plate 2, which can make the guiding plate 2 more stable when being pulled.

[0039] In this embodiment, a lifting ring 21 is arranged on the guiding plate 2, and a hook part 311 is arranged at one end of the pull rod 31 close to the guiding plate 2. The hook part 311 hooks the lifting ring 21, and by pulling the pull rod 31, the hook part 311 can pull the lifting ring 21 to move.

[0040] Lifting rings 21 are arranged at both ends of the guiding plate 2 along the conveying direction of the conveyor belt 100, and the two pull rods 31 correspond to the two lifting rings 21 one by one.

[0041] In this embodiment, an operation port is arranged on the cover plate 1, and a sealing cover 12 is installed in the operation port. A through hole is arranged on the sealing cover 12, and the pull rod 31 passes through the through hole. Therefore, the pull rod 31 can be pulled externally to directly adjust the position of the guiding plate 2.

[0042] In this embodiment, a tension spring 5 is arranged between the mounting bracket 4 and the guiding plate 2.

[0043] When the guiding plate 2 is in the first posture, the tension spring 5 is stretched. At this time, the tension spring 5 has a tendency to make the guiding plate 2 approach the belt of the conveyor belt 100, so that the guiding plate 2 can maintain the first posture.

[0044] When the guiding plate 2 is in the second posture, the tension spring 5 is also stretched. At this time, the tension spring 5 has a tendency to make the guiding plate 2 approach the cover plate 1, so that the guiding plate 2 can maintain the second posture.

[0045] When the pull rod 31 pulls the guiding plate 2, it overcomes the pulling force of the tension spring 5 to make the guiding plate 2 swing and switch different postures.

[0046] In this embodiment, an observation window 13 facing the guiding plate 2 is arranged on the cover plate 1 for observing the situation of the guiding plate 2.

[0047] In this embodiment, the guiding plate 2 includes a hard plate body and an elastic plate body. The hard plate body is hinged to the mounting bracket 4, and the elastic plate body is fixed on the hard plate body. The elastic plate body contacts the belt of the conveyor belt 100 and will not scratch the belt. At the same time, the position of the elastic plate body on the hard plate body is adjustable, and the length of the elastic plate body extending from the hard plate body can be adjusted.

[0048] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
