[0024] Example 1:

[0025] A conveying belt centering guide mechanism, referring to Figures 1-3, including the mounting structure 1 and the guide structure 2, the guide structure 2 includes two guide plates 21 which are spaced apart along the width direction of the conveying belt and are located above the conveying belt m, the two guide plates 21 limit the moving path of the material on the conveying belt, a gap between the end portions of the two guide plates 21 forms a discharge port 22 on the conveying belt m for the material to pass through, the guide plates 21 are rotationally mounted on the mounting structure 1, and any guide plate 21 can be rotated away from the other guide plate 21 under the impact of the material to increase the discharge port 22, and the guide plate 21 is provided with an elastic adjusting assembly 3, which has an elastic member 31 acting on the guide plate 21, for applying an elastic force to the guide plate 21 when the guide plate 21 rotates, to drive the guide plate 21 to elastically reset.

[0026] In the embodiment, when the size of the material is smaller than the size of the discharge port 22, the material can be directly conveyed to the designated position through the discharge port 22. However, when the size of the material is larger than the discharge port 22, the material moving on the conveying belt m will collide with the guide plate 21, the guide plate 21 will rotate under the impact of the material, so as to increase the discharge port 22, so that the material of large size can pass through the discharge port 22. At the same time, the elastic member 3 can apply an elastic force to the guide plate 21, and after the material passes through the discharge port 22, the guide plate 21 is driven to elastically reset, so that the discharge port 22 can maintain the original size, avoiding the position deviation of the material of small size. Compared with the prior art, different sizes of materials can be controlled on the designated position of the conveying belt without manual intervention, which has strong applicability, simple structure, low cost and is convenient for large-scale use in industry.

[0027] It should be noted that the size of the material directly affects the compression degree of the guide plate 21, the larger the size, the stronger the collision force on the guide plate 21, the higher the compression degree of the elastic member 31, and the greater the elastic feedback force, which is finally balanced at a certain position to form a discharge port 22 width matched with the material to ensure that the material passes through the discharge port 22.

[0028] In the embodiment, the elastic adjusting assembly 3 includes a positioning plate 32, the positioning plate 32 is arranged on the side of the guide plate 21 away from the material, and the elastic member 31 is arranged between the guide plate 21 and the positioning plate 32. When the guide plate 21 is rotated outward, the elastic member 31 is compressed to generate an elastic restoring force in the direction of the guide plate 21, so as to drive the guide plate 21 to reset. The elastic member 31 here can be a spring or a columnar body made of an elastic material.

[0029] In the embodiment, the direction of the elastic force applied by the elastic member 31 to the guide plate 21 is perpendicular to the rotation axis of the guide plate 21. At this time, the elastic force can be completely converted into an axial constraint force on the guide plate 21, so that the elastic member 31 can be maximally utilized to limit the rotation of the guide plate 21, and energy loss is reduced.

[0030] In the embodiment, the two guide plates 21 are symmetrically arranged along the central axis of the conveying belt m, and therefore, the position of the discharge port 22 is formed at the middle position of the conveying belt m in the width direction, so that the objects output by the discharge port 22 can be output from the middle position of the conveying belt m, avoiding the material from falling when being output from the conveying belt m.

[0031] In the embodiment, the mounting structure 1 includes two mounting frames 11 arranged on the two sides of the conveying belt m, and the conveying belt m is located between the two mounting frames 11. One end of each of the two guide plates 21 is rotatably connected to the two mounting frames 11, and the other end is located above the conveying belt m. In addition, at least one connecting piece is arranged between the two mounting frames 11, and the two mounting frames 11 can be connected as a whole through the connecting piece, which helps to improve the structural stability of the mounting structure 1.

[0032] In the embodiment, the side of the guide plate 21 close to the material is provided with a buffer assembly for contacting the material. The buffer assembly can absorb the impact force of the material when contacting the material, thereby reducing the impact of the guide plate 21 on the material on the conveying belt m. On the one hand, the wear of the guide plate 21 is reduced, which helps to improve the service life thereof. On the other hand, the material on the conveying belt m is prevented from being damaged by excessive impact, thereby playing a role in protecting the material. Specifically, the buffer assembly includes a plurality of buffer wheels 23 rotatably connected to the guide plate 21. The plurality of buffer wheels 23 are arranged along the extension direction of the guide plate 21. When the buffer wheels 23 contact the material, the buffer wheels 23 and the material are in rolling contact, i.e., the rolling friction therebetween. Compared with sliding friction, the rolling friction has a lower friction coefficient, which can reduce the friction force when the material contacts the buffer wheels 23, thereby avoiding damage to the surface of the object. At the same time, the plurality of buffer wheels 23 are arranged along the extension direction of the guide plate 21, which can uniformly disperse the impact force received by each buffer wheel 23, thereby improving the service life of the equipment.

[0034] A conveying device includes the conveying belt centering guide mechanism and the conveying belt m in embodiment 1.

Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for some technical features.
